Description

TECHNICAL FIELD The present invention relates to a method for filling a blood bag with a liquid, and particularly to prevent contamination of a liquid such as an anticoagulant of blood and a liquid medicine with the outside air, and mixing of foreign substances. The present invention provides a blood bag that does not occur and a method of filling a liquid into the blood bag. An example of the blood bag will be described below.

[Problems to be Solved by the Prior Art and Invention] Currently, as shown in FIG. 5, a medical bag 30 in which a blood component separation bag 32 and a drug solution bag 33 containing a drug solution are attached to a blood collection bag 31 is commercially available. However, the chemical solution bag 33 is
After filling the main body 33a with a chemical solution from the opening 34 through the liquid transfer tube 35, an adhesive is applied to the outer periphery of the opening 34 of the liquid transfer tube 35 to connect to the connection pipe 36, and the liquid transfer tube 37 is used. It was connected to the blood collection bag 31.

However, since the vicinity of the opening 34 of the liquid transfer tube 35 gets wet with the chemical liquid, the liquid transfer tube 35 is connected to the connecting pipe 36.
When connecting to, the adhesive may enter the inside of the chemical solution, or the liquid transfer tube 35 may be easily separated from the once connected connection tube 36, and the chemical solution may leak.

Then, the present inventor arrived at the following invention as a result of intensive studies to solve the above problems.

[Means for Solving the Problems] The present invention comprises a blood collection bag 2 having a blood collection tube 5 connected to the upper end thereof, a drug solution bag 3 for containing a drug solution, and a blood component separation bag 4, and a communication member 15 is provided at the upper end of the blood collection bag 2. The connecting pipe 12 is connected to the downstream side of the liquid transfer tube 7 connected via the liquid transfer tube 7, the blood component separation bag 4 is connected to one of the connecting pipes 12 via the liquid transfer tube 8, and the other end of the connecting pipe 12 is connected. The liquid medicine bag 3 is connected through the liquid transfer tubes 11 and 9, the connection pipe 13 is connected between the liquid transfer tube 11 and the liquid transfer tube 9, and the liquid medicine injection tube 10 is connected to the connection pipe 13. In the blood bag 1 having the communication member 14 arranged in the middle of the tube 11, the blood collection bag 5 is filled with an anticoagulant of blood from the opening 22 of the blood collection tube 5, and the blood collection needle 23 is attached to the opening 22. Sealing process A blood bag for filling the liquid by the step of filling the liquid medicine 3 into the liquid medicine bag 3 from the opening 25 of the liquid medicine injection tube 10 through the connecting pipe 13 and the liquid transfer tube 9 and heat-sealing and sealing the liquid medicine injection tube 10. A method for filling a liquid into a container is provided.

[Example] FIG. 1 shows a blood bag 1 of the present invention before being filled with a liquid.
Shows a schematic diagram of.

The blood bag 1 is composed of a blood collection bag 2, a drug solution bag 3, and a blood component separation bag 4, and these bags 2, 3, 4 are connected via liquid transfer tubes 7, 8, 9. A blood collection tube 5, a communication member 15, and an infusion port 16 are bonded to the upper end of the blood collection bag 2, and a liquid transfer tube 7 is attached to the communication section 15. A liquid transfer tube 9 and an infusion port 18 are attached to the upper end of the drug solution bag 3. The drug solution bag 3 is also attached to the upper end of the blood component separation bag 4.
Similarly, the liquid transfer tube 8 and the liquid transfer port 17 are attached.

Blood collection bag 2, drug solution bag 3, and blood component separation bag 4
As shown in FIGS. 1 and 2 (partially enlarged view of FIG. 1), a connecting pipe 12 is connected downstream of a liquid transfer tube 7 which is connected to the upper end of the blood collection bag 2 via a communication member 15. The blood component separation bag 4 is connected to one of the connecting tubes 12 via the liquid transfer tube 8, and the drug solution bag 3 is connected to the other of the connecting tubes 12 via the liquid transfer tubes 11 and 9.
Connection pipe between liquid transfer tube 11 and liquid transfer tube 9
13 is connected, the chemical liquid injection tube 10 is connected to the connection pipe 13, and the communication member 14 is arranged in the middle of the liquid transfer tube 11.

The blood collection bag 2, the drug solution bag 3 and the blood component separation bag 4 can be connected in the manner shown in FIGS. 3 and 4.

In the connection mode of FIG. 3, a T-shaped connection pipe 13a is arranged instead of the Y-shaped connection pipe 13 of FIG. 2, and the chemical liquid injection tube 10a is connected thereto.

The connection mode of FIG. 4 is the same as the connection pipe 13 of FIGS.
A connecting pipe 13b having a communication member 14b loaded therein instead of 13a.
(Y-shaped tube or T-shaped tube) is arranged and the chemical solution injection tube 10b is connected.

In the blood bag 1 of the present invention, the number of the drug solution bags 3 and the blood component separation bags 4 can be increased or decreased depending on the purpose of use. That is, when the whole blood component collected in the blood collection bag 2 is desired to be finely separated into platelets, plasma, white blood cells, etc., the numbers of the drug solution bag 3 and the blood component separation bag 4 can be increased.

Next, a method of filling the blood bag 1 with the liquid will be described. The liquid filling may be carried out simultaneously with the following two steps, or may be carried out after the step or, or the step or.

That is, as the first step: the nozzle 21 is attached to the opening 22 of the blood collection tube 5, the blood collection bag 2 is filled with the anticoagulant of blood through the blood collection tube 5, and the opening 22 is formed.
Attach blood collection needle 23 to and seal. The blood anticoagulant enclosed in the blood collection bag 2 is blocked from the flow path by the blood collection needle 23 and the communication member 15 and does not flow out to the outside.

As the second step: the nozzle 24 is replaced with the chemical injection tube 10.
Attached to the opening 25 of the, liquid medicine injection tube 10, connection tube 1
3. After passing through the liquid transfer tube 9, the drug solution bag 3 is filled with a physiological saline, a blood preservation solution such as SAG-mannitol as a drug solution, and the drug solution injection tube 10 is heat-welded and sealed.
Since the flow path is blocked by the communication member 14, the chemical liquid sealed in the chemical liquid bag 3 is unlikely to flow out.

[Effects of the Invention] As described above, according to the present invention, after the chemical solution is filled into the chemical solution bag 3 from the chemical solution injection tube 10, the chemical solution injection tube
Since 10 is sealed by heat welding, when the liquid transfer tube 35 is connected to the connection pipe 36 like the conventional blood collection bag 31, the adhesive enters the liquid medicine, and the liquid transfer tube 35 and the connection pipe 36.
Does not easily come off (in the present invention, when connecting the connection tube 11 to the connection tube 12, the connection tube 11
(The tip of is not wet with chemicals) Hygienic and safe separation of blood components can be performed.
