Description BACKGROUND OF THE INVENTION
This invention relates to a blood bag for use in collecting blood
and a blood collecting tube receiving member to be attached to the
blood bag.
Blood collection is generally done by using a blood bag. Collected
blood is transfused to a patient as it is (all components of blood).
Alternatively, only the necessary components separated from the
blood by centrifugation are transfused. Collected blood is examined
in order to avoid infection of an infectious disease, for example,
post-transfusion hepatitis such as hepatitis B and non-A non-B hepatitis,
AIDS (acquired immuno-deficiency syndrome), venereal disease, etc.
For this examination, after collecting blood into the blood bag,
the blood collecting needle of the blood bag system is withdrawn
from the donor and then pierces a sealing member (rubber plug) of
a blood collecting tube the interior of which is depressurized to
collect a sample of the blood in the blood bag. The sample of blood
is subjected to necessary tests.
On the blood collecting tube is a label having the same serial
number as a label stuck on the blood bag so as to check the blood
in the blood collecting tube being the same as that in the blood
bag. In many cases, however, plural blood collection works using
blood bags are parallelly done, for example, in a car for blood
donation. In such a car for blood donation, there are confusedly
present plural blood collecting tubes containing different blood.
As a result, there is a possibility that labels are erroneously
stuck on the blood collecting tubes. Besides, in the case that labels
are previously stuck on the blood collecting tubes prior to blood
collection works, there is a possibility that blood is collected
into a blood collecting tube from a wrong blood bag, that is, a
blood bag provided with the label having a different serial number
from that of the label on the blood collecting tube into which blood
is collected. Such erroneous affixation of labels or confusion of
blood bags is dangerous because blood having an infectious disease
may be transfused for mistaking it for safe blood.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide
a blood bag wherein, before lables are stuck on, a blood collecting
tube into which blood has been collected from this blood bag is
not confused with another blood collecting tube into which blood
has been collected from another blood bag, or after labels are stuck
on, blood is not collected from another blood bag into a blood collecting
tube which has a label having the same serial number as a label
stuck on this blood bag, so as to avoid the danger that blood having
an infectious disease is transfused for mistaking it for safe blood.
The above object is attained by a blood bag comprising a blood
collection container; a tube communicating with the blood collection
container and provided with a blood collecting needle at its distal
end; and a blood collecting tube receiving member attached to the
tube detachably or movably along the tube.
The above object is attained by a blood bag comprising a blood
collection container; a first tube communicating with the blood
collection container and provided with a blood collecting needle
at its distal end; a blood components container; a second tube connecting
the blood collection container to the blood components container;
and a blood collecting tube receiving member attached to the first
or second tube detachably or movably along the tube.
The above object is attained by a blood collecting tube receiving
member to be attached to a blood bag, comprising a blood collecting
tube mounting portion for mounting a blood collecting tube detachably,
and an attachment portion to the blood bag.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The blood bag of the present invention will be described with reference
to an embodiment shown in the drawings.
The blood bag 1 of the present invention comprising a blood collection
container 2; a tube 4 communicating with the blood collection container
2 and provided with a blood collecting needle 3 at its distal end;
and a blood collecting tube receiving member 5 attached to the tube
4 detachably or movably along the tube 4.
The blood bag of the present invention will be described with reference
to an embodiment shown in FIGS. 1 and 2.
The blood collection container 2 of the blood bag 1 is generally
called a master bag, in which anticoagulant is contained and which
is capable of receiving blood. In this example, the blood collection
container 2 is made of flexible synthetic resin into a bag. Anticoagulant
liquid contained therein may be well-known ACD liquid or CPD liquid.
The blood collection container 2 is made of flexible synthetic resin
having some extent of oxygen-permeability such as flexible vinyl
chloride resin and silicone resin because it is used as a red blood
cell reservoir after blood collection. A label 25 is affixed on
the surface of the blood collection container 2. The label 25 includes
labels 26 and 27 to be stuck on blood collecting tubes.
A first tube 4 is connected to the blood collection container 2
so as to be in fluid communication with the interior of the blood
collection container 2. The first tube 4 is made of flexible synthetic
resin such as flexible vinyl chloride resin and silicone resin like
the the blood collection container 2. A blood collecting needle
3 which is stabbed in a donor is attached to the distal end of the
tube 4. The blood collecting needle 3 comprises a hub 10 mounted
to the distal end of the first tube 4 in a liquid-tight manner,
a puncture needle mounted to the hub 10 and a protector 12 for
protecting the puncture needle 11. The protector 12 is detachably
attached to the hub 10 in a liquid-tight manner so as to prevent
anticoagulant in the blood collection container 2 from flowing out.
In the blood bag 1 of this example, a second tube 6 is connected
to the blood collection container 2. A blood component collection
container 7 is connected to the other end of the second tube 6.
The blood component collection container 7 is generally called a
slave bag. The blood bag is set in a centrifugal machine after blood
collection to separate blood collected in the blood collection container
2 into, for example, plasma component and blood cell component.
The blood component collection container 7 is used for collecting
the component separated into the upper part of the blood (for example,
plasma component).
The second tube 6 is provided with a breakable communicating member
13 to prevent anticoagulant in the blood collection container 2
from flowing in the blood component collection container 7 before
blood collection. Each of the blood collection container 2 and blood
component collection container 7 is provided with a blood outlet
8. The blood outlet 8 is closed and allows a connector of a transfusion
set (not shown) to penetrate.
In the blood bag 1 of this example, a blood collecting tube receiving
member 5 is attached to the first tube 4 detachably and movably
along the tube 4 as shown in FIGS. 1 and 2. The blood collecting
tube receiving member 5 may be attached to the first tube either
detachably or movably unlike this example.
It is preferable that the blood collecting tube receiving member
5 is capable of receiving more than two blood collecting tubes 15.
The reason is that the same blood is generally collected in more
than two blood collecting tubes according to different blood collection
manners in blood tests.
The blood collecting tube receiving member 5 of the example shown
in FIGS. 1 and 2 has holes 18 each of which allows the bottomed
tube 16 of a blood collecting tube 15 to be inserted therein and
is smaller than the sealing member 17 of the blood collecting tube
15. The blood collecting tube receiving member 5 also has an attachment
portion 19 to the first tube 4. The hole 18 preferably has the inner
diameter substantially equal to the outer diameter of the bottomed
tube 16 so as to hold the blood collecting tube 15 in slidable contact
with the outer surface of the bottomed tube 16. The blood collecting
tube receiving member 5 is attached to the tube 4 detachably and
movably along the tube 4. The blood collecting tube receiving member
5 can be made of a material having some extent of rigidity, for
example, polypropylene, polyethylene, vinyl chloride resin or polystyrene,
facilitating manipulation.
The blood collecting tube receiving member 5 is not limited to
this example but may have a hole 30 for the tube 4 passing through
so that the blood collecting tube receiving member 5 is attached
to the tube 4 not detachably but movably along the tube 4 as shown
in FIG. 3. In the case of the blood collecting tube receiving member
5 undetachable from the tube 4 like this example, the blood collecting
tube receiving member 5 is preferably made of a material not injuring
the blood bag upon centrifugation of the blood bag 1 for example,
elastomer such as flexible vinyl chloride resin and polyurethane,
or rubber material such as silicone rubber and latex rubber.
The blood collecting tube receiving member 5 may have such a large
hole 30 as to allow the blood collecting needle to pass through
as shown in FIG. 4 though the blood collecting tube receiving member
5 has a similar shape to that of FIG. 3. Thereby, the blood collecting
tube receiving member 5 is detachable from the tube 4.
Alternatively, the blood collecting tube receiving member 5 may
have a weak portion 32 extending from the hole 30 to the outer edge
of the blood collecting tube receiving member 5 as shown in FIG.
5 though the blood collecting tube receiving member 5 has a similar
shape to that of FIG. 3. Thereby, when the blood collecting tube
receiving member 5 is pulled, it is cut at the weak portion 32 so
as to be detached from the tube 4.
The tube 4 of the blood bag 1 is subjected to a heat seal operation
after blood collection. In the heat seal operation, blood in the
tube 4 is divided into four to eight sections between the portion
of the tube 4 at which the blood collecting needle is attached and
the vicinity of the blood collection container in order that the
blood is used in cross matching tests. In this case, the blood collecting
tube receiving member 5 does not obstruct the heat seal operation
because it is attached to the tube 4 detachably or movably along
the tube 4.
The blood collecting tube receiving member 5 may be attached to
the second tube 6 connecting the blood collection container 2 to
the blood component collection container 7.
In this manner, by attaching the blood collecting tube receiving
member 5 to the first or second tube 4 or 6 detachably or movably
along the tube, the tube position easy for blood collection into
the blood collecting tube 15 can optionally be selected, facilitating
the blood collection work.
The blood collecting tube receiving member 5 may be constructed
as shown in FIGS. 6 and 7. FIG. 6 shows a front elevation of the
blood collecting tube receiving member 5 which receives blood collecting
tubes. FIG. 7 is a bottom view of FIG. 6. The blood collecting tube
receiving member 5 of this example has an attachment portion 19
for detachably holding the first or second tube 4 or 6 and two
pairs of fixing portions 20 for blood collecting tubes. This blood
collecting tube receiving member 5 is easy of manipulation because
it can be had in the state that two blood collecting tubes 15 are
fixed to it as shown in FIG. 6 and it is detached from the tube.
Because the blood collecting tube receiving member 5 can be attached
to any portion of the tube, the tube position easy for blood collection
into the blood collecting tubes 15 can optionally be selected. It
is thus possible that the blood collecting tube receiving member
5 previously fixing plural blood collecting tubes 15 is provided,
attached to an optional position of the tube 4 and after blood
collection, detached from the tube 4 together with the blood collecting
tubes 15.
In a preferred form of the blood collecting tube receiving member
5 it is possible to collect blood into the blood collecting tube,
stick labels on the blood collecting tubes, and check the serial
numbers of labels of the blood collecting tubes and blood bag in
the state that the blood collecting tube receiving member 5 is attached
to the blood bag 1. The order of steps of collecting blood into
the blood collecting tube and affixing the labels is optional. All
of the examples described above meet these requirments. Although
the blood collecting tube receiving member 5 is attached to the
tube in the examples described above, the blood collecting tube
receiving member 5 may be attached to, for example, the hub or protector
of the blood collecting needle 3.
The operation of the blood bag of the present invention will be
described with reference to the embodiment shown in FIGS. 1 and
2.
First, the blood collecting tube receiving member 5 is attached
to the blood bag 1. A blood collecting tube 15 is inserted in and
fixed to each of the holes 18 constituting the blood collecting
tube fixing portion of the blood collecting tube receiving member
5. Next, labels 26 and 27 for blood collecting tubes which are parts
of the label 25 stuck on the blood collection container 2 are peeled
off and then stuck on the surfaces of the bottomed tubes 16 of the
blood collecting tubes 15 respectively. At this time, it is checked
that the serial number of the labels of the blood collecting tubes
15 corresponds to that of the label of the blood collection container
2. Subsequently, the blood collecting needle 3 is stabbed into a
donor to collect blood into the blood collection container 2. After
the blood collecting needle 3 is withdrawn from the donor, it is
made to pierce the sealing member 17 of one of the blood collecting
tubes 15 to collect a part of the blood of the blood bag into the
blood collecting tube 15. The operation of collecting blood from
the blood bag is repeated twice. After this, the blood collecting
tubes 15 are separated from the blood collecting tube receiving
member 5 and necessary blood tests are carried out. At this time,
if the blood collecting tube receiving member 5 is detachable from
the tube 4 it may be detached together with the blood collecting
tubes 15. The labels 26 and 27 may be stuck on the blood collecting
tubes 15 after blood collection into the blood collecting tubes
15.
The blood bag of the present invention comprises a blood collection
container; a tube communicating with the blood collection container
and provided with a blood collecting needle at its distal end; and
a blood collecting tube receiving member attached to the tube detachably
or movably along the tube. Therefore, it is advantageous because,
before labels are stuck on, a blood collecting tube into which blood
has been collected from this blood bag is not confused with another
blood collecting tube into which blood has been collected from another
blood bag, or after labels are affixed, blood is not collected from
another blood bag into a blood collecting tube on which has been
affixed a label having the same serial number as a label on this
blood bag, so as to avoid a danger that blood having an infectious
disease is transfused by mistaking it for safe blood.
The blood bag of the present invention comprises a blood collection
container; a first tube communicating with the blood collection
container and provided with a blood collecting needle at its distal
end; a blood components container; a second tube connecting the
blood collection container to the blood components container; and
a blood collecting tube receiving member attached to the first or
second tube detachably or movably along the tube. Therefore, it
is advantageous because, before labels are stuck on, a blood collecting
tube into which blood has been collected from this blood bag is
not confused with another blood collecting tube into which blood
has been collected from another blood bag, or after labels are stuck
on, blood is not collected from another blood bag into a blood collecting
tube on which has been stuck a label having the same serial number
as a label stuck on this blood bag, so as to avoid the danger that
blood having an infectious disease is transfused by mistaking it
for safe blood.
The blood collecting tube receiving member of the present invention
to be attached to a blood bag, comprises a blood collecting tube
mounting portion for mounting a blood collecting tube detachably,
and an attachment portion to the blood bag. Therefore, it is advantageous
for the same reason as the above blood bag. |
