BACKGROUND OF THE INVENTION
[0002] For medical safe reason, the principle of syringe treatment
is one-off used, then, used-syringe be sterilized and destroyed
carefully to avoid repeated use or hurt people by uncontrolled discard.
It is a highly risking period between syringe after used and before
destroyed. However, even kinds of safety syringe developed, medical
worker affect with fright of and to be aware that people hurt by
used-syringe accident still happen due to not proper safety syringe
designed or inconvenient syringe operated. Therefore, currently
critical issue is to resolve the shortcoming of prior art, and to
invent an operated simply, safe of new syringe designed and improve
the security of operation people during syringe used to destroy.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0016] Referring FIGS. 12 & 3 a present invention includes
a barrel 1 a plunger 2 a connecting member 3 and a cover cap 4.
Said barrel 1 is a hollow cylinder with injection liquid filled
inside, at a front arranged with a barrel tip 11 and a barrel joint
12. Said tip 11 contains an injection passage 111 for injection
transmission purpose. Said joint 12 made to connect said connecting
member 3 is an extended tube with a reduced diameter and associated
with a space as joint space 123 to a retaining flange 122. Said
joint 12 disposed to connect said injection passage 11 a linker
channel 121 having a retaining flange 122. At rear end of said
barrel 1 has a syringe handle flange 13 for easy handling. Said
plunger 2 at inside of said barrel 1 provides an outward pressure
to the inside liquid of said barrel 1 to pass through injection
passage 111 which located in barrel tip. Said the connecting device
of connected member 3 and said barrel joint 12 has two coaxial rings.
The one inner connecting ring 31 near to core for completely inlaid
to linker channel 121 associated with a fix flange 311 extended
at said inner ring 31 end for either tightly covering said linker
channel 121 or tight down in a thread connection. Besides, another
outer connecting ring 32 arranged at least an extending snapping
knob 321 which knob is projecting over said connecting member 3
and with side groove 322 enclosed at its two sides. Straight said
snapping knob 321 top part forms a tab fitting coupling 323 and
said tab-coupling 323 having another tab fitting as a coupling member
33 both of tab fittings are for coupling to the track of the socket
path. The elements of said connecting member 3 top part contain
a seat 34 a connecting joint 35 and a connected tip 36. Said seat
34 for bearing force from an elasticity element 37 located at periphery
of said member 3 a connecting joint 35 and a connected tip 36 located
at an inside of said connecting joint 35. A connected channel 38
is arranged between said connecting joint 35 and said connected
tip 36 for tight fixing, supporting to a locking tip 39. Said connected
channel 38 and said locking tip 39 could be connected in threading,
capping or extruded. Additionally, in the interior side of said
connected tip 36 has a central passage 361 linking to said injection
passage 111 and to a needle cannula 391 for liquid outlet. Said
cover cap 4 covering with said connecting member 3 an L-form socket
path, contains at least a socket track 41 and a start-side-socket
42. Said socket track 41 links an end-side-socket 43 associated
with a vertical direction and, on the direction to said barrel 1
has a guide socket 44 extending parallel with a socket track 41.
Said guide socket 44 is formed at interior side of said cover cap
4 for guiding said coupling member 33 into said end-side-socket
43 and said socket track 41. Said start-side-socket 42 arrange
a stopper cell 421 linking to said socket track 41 on another side
of said end-side-socket 43. Said cover cap 4 top part comprises
a tuber front 45 for settling said locking tip 39 in, containing
an open mouth as a tuber front mouth 451 for said needle cannula
391 passing through, further, to bear force from elasticity element
in said cap 4 interior top side. Shown in FIG. 4 before said cover
cap 4 capping said connecting member 3 said guide socket 44 directed
toward said coupling member 33 to lead said coupling member 33 filling
and moving by said end-side-socket 43 guide socket 44 then into
socket track 41. Further, shown as FIG. 5 to forward said coupling
member 33 into the end track of said socket track 41 "A"
mark. Shown as FIG. 6 said tab coupling 323 a tab-fit designed,
connects to said cover cap 4 and fills into another end track of
said socket track 41 "B" mark, at this moment, the space
between seat 34 of said connecting member 3 and interior side of
cover cap 4 is pressed hard by a elasticity element 37 additionally,
the assembly of said cover cap 4 and said connecting member 3 is
finished.
[0017] After-used-syringe is shown as FIG. 6 to FIG. 8 medical
worker pressing said coupling shield 321. Since said coupling shield
321 has said side groove 322 around at two sides of them which make
said coupling shield 321 easy to be pressed down and entering into
said joint space 123 of said barrel 1. Further more, shown as FIG.
3 said tab coupling 323 will be out of coupling and connecting
to said socket track 41 at meanwhile, said cover cap 4 forced by
said elasticity element 37 to be spring outward and to seal up said
needle cannula 391. In addition, said coupling member 33 moves by
the track of said socket track 41then, to be stock in the position
"B" (mark as B). Moreover, to turn said cover cap 4 to
guide said coupling member 33 to fill into said stopper cell 421
finally, to keep said cover cap 4 in safe guard status.
[0018] Another embodiment of present invention is shown as FIG.
9 and FIG. 10 said connecting member 3 has a press shield 324 which
is a flexible cover, project over said connecting member 3 and having
a tab coupling 325 for making a coupling connection relationship
to said cover cap 4. Said cover cap 4 in facing front to said press
shield 324 has an extending cover 46. At interior side of said
cover 46 arranges a track 461 for couple matching to said tab coupling
325 in a safeguard status, further, said locking tip 39 in associated
with said connecting member 3 being made extrusion. A needle cannula
391 places in said locking tip 39. A space as a linker channel 392
is surround said locking tip 39. Said locking tip 39 and the inside
of said cover cap 4 top are bearing the force from two end of elasticity
element 37.
[0019] The other embodiment is shown in FIG. 11A and B, a stopper
cell 422 straightly arranged at the end of said cover cap 4 or a
stopper cell 423 arranged on the one side of said socket track 41
end, to achieve fixing forward and operating simply purpose.
[0020] According the above, a feature of the present invention
is the provision a safe guard syringe by simple operation procedure,
for security of medical worker from using syringe to destroy. Additionally,
the present invention is more practically and safe, since there
is a two-dimension protection designed to ensure the safety of used-syringe.
[0021] Many changes and modifications in the above-described embodiment
of the invention can, of course, be carried out without departing
from the scope thereof. Accordingly, to promote the process in science
and the useful arts, the invention is disclosed and intends to be
limited only by the scope of the appended claims. |
