Wheel chair description
BACKGROUND OF THE INVENTION
The present invention provides the structure of an adjustable,
multi-purpose type of sick bed that can serve as a wheel-chair for
sitting or lying on and is easily assembled and disassembled, on
which the patient may take a bath, urinate or discharge bowel movement
comfortably. The bed stand, that is, the mattress, is composed of
three web-like sections which are pivotally associated with each
other. On the underside of each of the forward and rear sections
is provided a rocker gear adjustment means such that, by adjusting
the frontal section of the bed to tilt upwardly and adjusting the
rear section thereof to tilt downwardly therewith, the sick bed
can be converted into a wheel-chair as needed. In a position in
the central section of the bed is provided a hollow-set soft urn
in association with a sump and drainage underneath. The urn to accommodate
discharge of urine and feces as eliminated by the patient lying
in the bed in a manner as comfortable as if it were his or her private
toilet. For this purpose, a plastic covering may be hung vertically
to conceal the underside of the frontal section and of the rear
section of the spring mattress together. With a drainage pipe connected
to the sump, this also permits the patient to take a bath in the
bed, the sullied bath water being confined by the covering shields
to flow to the drainage pipe for exhaust. Thus, the bed can be maintained
clean and convenient for reclining afterwards.
While advances in medical sciences have come to such a point as
to bring much benefits to human beings by relieving their pains
and contributing to their health, there is no denying that a thoughtfully
designed, ideally structured sick bed is also indispensable. Various
services to patients suffering from body amputation and disability,
who have to rely on the bed all the time at times during their illness
or even all their life, are concerned in addition with medical support.
A conventional sick bed is generally of such a structure that incorporates
a fixed type level plank mattress, so that when the patient is unable
to walk on foot and has to remain in bed for one reason or another,
but has to take pills or have his meals at mealtime, the pillows
have to be stacked higher to bring the patient's head higher than
the rest of his body in order to feel comfortable while taking the
pill or his food. Yet the patient can hardly feel comfortable enough
by such efforts of adjustment, and it is a nuisance and inconvenience
to have to do so. Thus, the prior proposal has been made to provide
a sick bed that permits slight rotative adjustment of the head position.
Still, such a design is subject to the following shortcomings.
1. The lack of the provision of a weblike spring mattress and of
a hollow sink in the center of the bed means the patient will have
to be assisted by the nurse or some non-patient to get to the toilet
or when he needs to have his body cleaned and must be assisted back
to the bed again. Such assistances are truly a bothersome burden
for the assistants, who have to be constantly attentive lest the
patients fall down en route. If the patient remains in bed for body
cleaning, while this may be all right in cool weather, in some climates
it is hardly practicable in summer when it is so hot that the body
has to get soaked through in a shower or bathtub in a toilet room
or lavatory in order to avoid skin disease and foul smells.
2. For the entire sick bed only the head position is provided a
rotative movement of a small amplitude. While this relieves the
trouble of having to stack the pillows high. The bed cannot be converted
to a wheel-chair that would best benefit the patient if he wishes
to lift himself to read or write, or simply to sit up at least once
in a while. When he is restricted from body movement by foot, this
failure is particularly a pity for those patients who can take solace
in reading in a comfortable sitting position.
3. The bed stand, being integral with the castor support by welding,
as such cannot be taken apart, takes more space and permits little
flexibility for handling and being transported form one place to
another, incurring much labor charge and much inconvenience.
4. The necessity to fix an injection fixture and food tray beside
the sick bed, which usually occupies space overlapping the aisle,
when the patient is injected or having his meal in bed, affects
passage by the medical staff in moving from one ward to the next.
It is in view of the foregoing shortcomings and drawbacks of conventional
sick beds, that the inventor betook himself to work for improvements
therefor, and eventually succeeded in the presentation of the present
invention.
SUMMARY OF THE INVENTION
Accordingly, the primary objective of the present invention is
to provide such an adjustable, multi-purpose wheel-chair type of
sick bed, of which the spring mattress is composed of three sections,
the forward and the rear sections each being provided with a rocker
gear adjustment means, which can function to adjust the tilt slope
of both sections with respect to the bed stand, so that the mattress
may be converted virtually form a level position to a wheel-chair,
so that the patient in bed can shift from a reclined posture to
a sitting posture without supports or assistances from other people,
all by himself.
A further object of the present invention is to provide such an
adjustable, multi-purpose wheel-chair type sick bed, whereof the
mattress is made of a weblike network. A plastic covering is provided
for hanging as a shielding fence enclosing the frontal and the rear
sections, so that the patient may take a bath right on the bed.
The sullied water of the bath flows into the sump for exit via a
drain from the sump.
A further objective of the present invention is to provide such
an adjustable, multi-purpose wheel-chair type of sick bed, wherein
a soft urn, serving the purpose of a bedpan, is provided in engagement
with a correspondingly curved hollow provided in the central portion
of the bed, to accommodate urination or stool discharge by the patient
in the bed, the excrement being collected by falling into the drainage
system via the sump. A urinal or toilet can be provided at the outlet
of the sump.
A further objective of the present invention is to provide such
an adjustable, multi-purpose wheel-chair type sick bed, which incorporates
a pair of handrests on both sides of the mattress to serve as guard
rails when the patient is sleeping in the bed. Such a pair of handrests
may serve to be rested upon by the patient's elbows when the sick
bed is converted to and serves the purpose of a regular wheeled
armchair, and incorporates a pair of handles as extensions of the
two handrests to serve the purpose of handles to facilitate pushing
when the sick bed is converted to a wheel-chair.
A further object of the present invention is to provide such an
adjustable, multi-purpose wheel-chair type sick bed, whereof a fixing
hole is provided in front of each handrest on both sides of the
middle of the sick bed, to facilitate the insertion of a supporting
stem to which objects such as an injection bottle, towels, cups,
etc., can rest upon. It is further possible to put a cushion board
between the pair of handrests abeam the handle, on which newspapers,
magazines, other things may be put for reading. This allows other
enjoyments by the patient in bed, including serving meals in bed,
without having to use additional floor space, so that the medical
staff may move around the ward with more ease.
A further objective of the present invention is to provide such
an adjustable, multi-purpose wheel-chair type sick bed, which is
made of module parts that can be assembled and disassembled with
equal ease, so that handling and transportation can be made with
the utmost convenience. This permits saving space and is convenient
at many times, even if the bed is in active use.
Other features and advantages of the present invention will emerge
from the following descriptions of embodiments which are given by
way of illustration, but are not intended to be in any way limiting,

DESCRIPTION OF PREFERRED EMBODIMENTS
Referring first of all to FIG. 1, it is seen that the adjustable,
multi-purpose wheel-chair type of sick bed of the present invention
is composed essentially of two handle rails 100, the bed planking
200, a sump 300, and two adjustment means 400.
We begin with a detailed description of the handle rail section
100. A pair opposite each other are provided, having a chassis rod
14 provided on the underside, and a bent handle section 10 on top.
The chassis lever 14 is integrated with the bent handle section
10 by two pillars 13 welded thereto. The handle rail section 100
is provided with a handrest 11 in the middle, and its tail end is
turned up for extension into a handpush 101 which is coupled with
handle 12. The chassis rod 14 is provided with wheels 15 at the
front and rear, and the wheels 15 are provided with stays 16, to
facilitate retention of the location of the wheels 15, as desired.
Reference is made to FIG. 2 for further descriptions of the assemblage
of other essential parts comprising the sick bed of the present
invention.
The chassis foundation of the bed has a pair of handle rails 100
fitted on either side, to permit fixing of the pillars 13 integrally
with the handle rails 100. The pillars 13 are secured by the adjustment
means 400 via the penetration holes 132 at the front of one pillar
13, and another adjustment means 400 is to be screwed to a passage
hole 133 at the rear of another pillar 13, below the handle rails
100, whereby the handle rails 100 and the adjustment means 400 serve
as the chassis of the bed.
As regards the bed planking 200, it is fitted between the two handle
railings 100 by having screws engaging the screw holes 2021 in the
middle section 202 of the bed, at an elevation approximately 20
cm below the handrest 11. A movable rod stay 242 is provided below
each of the front section 201 and the rear section 203, respectively,
to facilitate coupling with the adjustment means 400 of which the
detail will be given later in the text.
The sump 300 is located directly below the central section 202
of the bed, which is fixed to the pillar 13 relative to both handle
railings 100 by screws respectively.
The disclosure thus makes clear how the first advantage of the
sick bed of the present invention is achieved, that is, the bed
permits easy assembly and disassembly without having to use much
space, and easy transportation and handling.
Referring to FIG. 4, a detailed analytical view of the bed planking
200 portion of the invention is shown, in which the bed planking
200 comprises such parts as the bed frame 20, bed surface 26, surface
fitting 29, excremental urn 28, plastic covering 27 and strut 24.
The bed frame 20 is composed of a forward section 201, a middle
section 202, and a rear section 203. The framework of the forward
section 201 resembles the letter n shifted by ninety degrees in
the counterclockwise direction, and that of the rear section 203
resembles the letter n shifted by ninety degrees in the clockwise
direction. The middle section 202 has a square form and includes
the arched stems 21 curving down on both sides and four reinforcement
plankings 22 distributed equidistantly thereon, so as to reinforce
the structure of the middle section 202 to bear heavier loads.
For the embodiment of the forward section 201 and the middle section
202, reference is made to FIG. 3, in which is seen a coupling hole
2011 over the tail end of the front section 201, and a coupling
fin 2022 projecting on both sides of the middle section 202. Pin
holes are provided in both the coupling hole 2011 and the coupling
fin 2022. As the coupling fin 2022 is engaged into the coupling
hole 2011, for articulated coupling, the front section 201 can be
angularly adjusted with respect to the coupling. In much the same
procedure, the middle section 202 can be coupled with the rear section
203 by interactions of coupling holes with coupling tips and fins,
so that the rear section 203 may also secure angular adjustment
with respect to the coupling pins.
Once the forward section 201, the middle section 202 and the rear
section 203 have been assembled together to provide the bed frame
20, the surface or sheet 26 may be spread over the bed frame 20.
The surface 26 has a weblike 261 formation and made of plastic materials
of high strength, for being spread over the bed frame 20 with a
tight fit, with its perimeter wrapping over the lower side of the
bed frame and being locked in place by pressure from a number of
surface fixing pieces 29. In the center of the surface 26 is provided
an annular opening 262 for coupling with the excremental urn 28.
The excremental urn 28 is composed of an annular upper hollow hold
281 and a lower fixing ring 282. The upper hollow hold 281 is soft
and wide enough on top, for hanging over an annular access hole
262 in the center of the bed spread. Screw threads are provided
on the underside protruding down into the annular access hole 262,
and for being fixed by the lower fixing ring 282. As is seen by
reference to FIG. 2-1, the inner hole 2811 in the hollow hold 281
is the excremental stool for urination and excremental discharges
by the patient reclined on the bed.
A watertight plastic covering 27 is provided below the front section
201 and the rear section 203 of the bed spread, having a number
of hook rings 271 fixed at equal intervals over the three sides,
to facilitate hanging of the plastic covering 27 about the forward
section 201 and the rear section 203 of the bed stand when in use,
and for easy removal when not in use.
A pair of struts 24 are provided, below the forward section 201
and below the rear section 203, each including two supporting lugs
23, a shaft lever 241 and a stay rod 242. The support lug 23 looks
like an ear for locking to the base of surface fitting 29 below
the lower rims of both frames of the frontal section 201 and the
rear section 203. The shaft lever 241 couples with the stay rod
242, and both ends of the shaft lever 241 are fitted to the support
lugs 23 on either side. The stay rod 242 is configured like the
letter T, and the internal diameter of the cross sleev ing 2421
is greater than the outer diameter of the shaft lever 241 to bring
it to an articulated setting when fitted over the shaft lever 241.
The stay rod 242 is welded securely in a vertical direction from
the center of the cross sleeving 2421, and its tail end is fitted
with a coupling slot 2422 and a pin hole 2423. This facilitates
coupling with the link 472 in the bed layout adjustment means 400,
which detailed description will be given later in the text. Also,
to accommodate the adjusting direction of the forward section 201
as compared to that of the rear section 203, as seen in FIG. 6,
the length of the stay rod 242 below the front section 201 is longer
than the stay rod 242 below the rear section 203.
Referring to FIG. 5, an analytical perspective of the invention
sick bed is shown, wherein the bed adjustment means 400 is composed
of a master bearing mounting 40, a crucial plate 41 and a transmission
consisting of gear sets. The master bearing mounting 40 is a rectangular
member, having a passage hole 401 provided on each of the four corners,
to facilitate coupling with the pillar 13 fastened with screws on
the handle railing 100. The crucial plate 41 is a flat plate for
being screwed onto the central part of the master bearing support
40. Bearing mountings 42, 43 are provided on both ends of the crucial
plate 41 on both sides of the master bearing mounting 40 as well.
The four bearing mountings are colinear. A transmission shaft 44
is mounted in the bearing mountings 42, 43, the central position
of the transmission shaft 44 being fitted with a worm stem 441.
Both sides of the transmission shaft 44 are provided with square
heads 442. Below the center of the crucial plate 41 is provided
a bearing mounting 49, on the top of which are provided two internal
holes 491 to accommodate the bearing 50. At the bottom of the worm
gear 48 is provided a mandrel 482 for fitting in the bearing 50
for rotation. On top of the worm gear 48 is welded a bevel gear
481, such that the worm gear 48 engages with the worm stem 441 perfectly
as the mandrel 482 in the bottom of the worm gear 48 is inserted
into bearing 50. On both sides of the crucial plate 41 are provided
by projection an axle fitting block 45. The axle 46 couples into
the tubular shaft 47, to have both sides screwed to fixing holes
451 on both ends of the axle fitting block 45 by screws. The center
of the tubular shaft 47 has an inner opening, of which the inner
diameter is a little bit greater than the outer diameter of the
axle 46, such that the tubular shaft 47 can be articulated to a
desired setting upon engagement. To one side of the tubular shaft
47 is welded a bevel gear 471, for engagement with bevel bear 481
on top of the worm gear 48. To the tubular shaft 47 is welded a
link 472 having a pin hole 4721 provided on its top, to facilitate
coupling securely with the slot 2422 at the tail end of the stay
rod 242 on the rear section of the bed 203 upon engagement with
the link 472. A better understanding may be had by reference to
FIG. 5-1.
The assemblage of the various parts in association with the adjustment
means 400 is such that the coupling of link 472 with stay rod 242
controls pivoting of, for instance, the rear section 203 of the
bed stands as a result of the worm stem 441 being in transmission
with worm gear 48, when the rocker arm 6 is engaged onto any of
the four square heads 442 on any side of the transmission shafts
44 for rotation. The bevel gear 481 rotates the bevel gear 471 on
the transmissive tubular shaft 47, so as to result in up-and-down
swinging of the link 472. This, coupled with stay rod 242 interconnected
with the link 472, brings about angular displacement of the rear
section 203 of the bed.
The bed adjustment means in the forward section 201 and in the
rear section of the bed stand are identical, permitting also easy
regulation of the angular setting of the front section 201 of the
bed. According to results obtained from various experiments conducted
by the inventor, the front section 201 can be adjusted from the
level position to an upswung position of 80 degrees, referred to
as angle alpha, whereas the rear section 203 also permits adjustment
from a level, reference position to a downswung position of 80 degrees,
referred to as angle alpha, and in addition adjustment to an upswung
position of 20 degrees, referred to as angle beta, as is better
seen in FIG. 6. This makes it possible to adjust the head and the
legs of the patient reclined in bed to any angular displacement,
for his own benefit and as he pleases.
Thus, another important function of the subject invention has been
described, namely easy adjustment of the surface of the sick bed.
Referring once again to FIGS. 1 and 2, it is seen that the sump
300 is fitted crosswise by fastening it via the screw holes 131
onto the strutting supports, directly below the central section
202 of the bed. The width is about the same as the width of the
middle section 202, the interior sloping down in convergence to
a central drain 30 in the center.
The excremental urn 28 is provided under a point in the central
area of the middle section 202 of the bed spread formed, together
with the sump 300. A flat plate 3 is positioned crosswise between
the pillars 13 on the chassis rod 14, and a urinal 5 is placed directly
below the central drain 30 in the sump 300 on the flat plate 3.
These are arranged to facilitate urination and excremental discharge
by the patient lying in bed. The excremental urn 28 serves for all
purposes and intents as a bed pan, so that the excrement may discharge
to the urinal below via the drain 30 in the sump 300.
This explains another feature of the sick bed of the present invention,
namely, the facilitating of natural elimination by the patient directly
from the bed, without having to leave the bed.
The enclosure defined by the plastic covering 27 hanging down the
front section 201 and the rear section 203 of the bed spread, in
relation to the weblike eyelets 261 on the bed surface 26, with
the sump 300 in the center, whereby a drainage pipe is connected
outdoors via the drain 30 in the sump 30, altogether accommodates
the patient on the bed to take a bath in the bed. The sullied bath
water finds its way out into the sump 300 by the openings 261 in
the web 26, and is laterally limited by the plastic covering 27,
to eventually pass out the drain 300.
This explains another feature of the sick bed of the present invention,
namely, the permitting of the patient to take a bath in bed, that
is, without having to leave the bed.
In addition to such significant advantages realized by the present
invention, to accommodate to the patient's having a meal in bed,
taking pills or reading pastimes, the bed stand is structured to
permit adjustment to a wheel-chair for such purposes. Furthermore,
an object support 2 can be removably provided as an extension form
the aisle side of the handrest 11, such as an object stand 2 supported
by reed inserts 7 on both ends of the bottom of the object stand
2. This facilitates fitting of such reed inserts 7 straddling over
the handrest 11 when the flat plate 2 is to be used, in a secured
position free from incidental displacing effects.
A fitting hole 102 is provided on either of the two handrests 11,
to facilitate fitting of cupboard or injection supports.
A flat board 4 is provided in front of the base chassis lever 14
relative to the two handrests 100, to accommodate setting of reading
materials thereon.
The disclosure thus makes clear how the many advantages provided
by the adjustable, multi-purpose wheel-chair type of sick bed of
the present invention to hospitalized patients, particularly those
patients who have to remain in bed the whole day due to disability
or amputation. The bed of the present invention is especially remarkable
in the following respects:
1. All constituent parts permit easy assembly and disassembly,
handling and transportation and saving of space.
2. The bed surface is structured in a weblike configuration for
facilitating ventilation, and for permitting the patient in bed
to take baths in bed by drawing down the plastic covering shields
removably fitted thereto.
3. An excremental urn is provided on the bed surface serving the
purpose of a regular bedpan, to facilitate discharge of urine and
feces by the patient in bed without departure from the bed.
4. A handrest portion is provided higher than the surface level
of the bed, to function as a protective means while the patient
is reclined in bed, to prevent the patient from rolling on the ground
during sleep, and to function as a handrest when the patient sits
up to have a meal or to read.
5. The surface of the bed and the bed stand are structured in three
sections, which, together with bed adjustment means provided in
addition, permit adjustment of the bed stand to any suitable position
as determined by the patient himself, even to be converted virtually
into a wheel-chair, so that the patient may be pushed or have himself
pushed outdoors to get some exposure to sunshine or for outdoor
activities by actuating the wheels underneath, by exertion of the
handrests or handles.
6. The fitting holes are provided on the handrest and extensions
thereof to accommodate cupboards or injection support, and a flat
board can be hung crosswise over the handrailings, to facilitate
the patient taking his meal in bed, or for enjoying reading in bed,
which can be easily removed when no longer needed for use for the
time being.
The disclosure thus makes clear the merits of the bed of the present
invention for use by hospitalized patients, particularly those suffering
from hemiplegia, cerebral congestion, other diseases whereby the
patient has lost control of himself for days, weeks, or longer,
or who has to linger in bed for long periods, for whom eating, body
cleaning, and natural discharges can be handled or taken care of
in bed, in a bed structured as claimed hereunder. |
