Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to improvements in medical bags used to collect and preserve blood or to separate blood into various components.

(Prior Art) A currently used medical bag 30 has a blood sampling needle 33 attached to a parent bag 31 via a blood sampling tube 32, as shown in FIG. One or more child bags 35 are further attached to the parent bag 31 via a connecting tube 34.

The blood collection needle 33 includes a needle base 38 in which a needle cap 36 and a needle 37 are implanted, and a blood collection tube 32 is connected thereto.

(Problems to be Solved by the Invention) However, the medical bag 30 configured as described above is made of hard synthetic resin in order to coil the tubes, store them in a packaging container, and perform high-pressure steam sterilization. and the connection points of the tubes formed of soft synthetic resin, that is, the needle base 38 and the blood collection tube 32, the connection tube 34 and the connection tube 3
In the vicinity of the connection point 9, the tube made of soft synthetic resin was prone to breakage (see FIGS. 5a and 5b).

For this reason, when using this fold,
Blood, plasma, etc. stagnate, and especially in the case of highly viscous blood, clots are likely to occur, which is not preferable for blood collection operations that require rapid processing. In order to solve the above problems, the present inventor conducted intensive studies and arrived at the following idea.

(Means for Solving the Problems) The present invention has a tubular member made of a soft synthetic resin and a tubular member made of a hard synthetic resin, and a tubular protector is provided on the outer periphery of at least one of these connection points. The present invention provides a medical bag to which a medical bag is wrapped (fixed).

(Function) As described above, since the outer periphery of each connection point of the tubular member (tube) made of hard synthetic resin and soft synthetic resin is protected by the protector, each tubular member (tube) made of soft synthetic resin is protected by the protector. ) is rolled up into a spiral and stored in a packaging container, the load on each soft tubular member (tube) is significantly reduced, so blood, plasma, etc. can be transferred smoothly during use without bending. .

(Example) An example of the present invention will be described with reference to the drawings. FIG. 1 shows a schematic diagram of a medical bag 1 of the present invention.

A blood sampling needle 5 is attached to the parent bag 3 via a blood sampling tube 4. One or more child bags 9 are further attached to the parent bag 3 via a connecting tube 6, a connecting tube 7, and a Y-tube 8.

10 and 11 are protectors, which include a tubular member made of a hard synthetic resin, a tubular member made of a soft synthetic resin, a needle base 12 of the blood collection needle 5 (a tubular member made of a hard synthetic resin), and a blood collection tube 4 (a tubular member made of a soft synthetic resin). (a tubular member made of resin), a connecting tube 6 (a tubular member made of relatively hard synthetic resin (having elasticity to the extent that the communicating piece loaded inside can be broken when external pressure is applied)), and a connecting tube 7 (a tubular member made of soft synthetic resin) is wrapped (fixed) around the outer periphery of each connection point.

Next, an example of a protector used in the medical bag 1 of the present invention will be described.

FIG. 2 shows a first embodiment of the protector.
Its structure consists of each tubular member (each tube 4, 6, 7,
It consists of a gripper 14 of the needle base 12) and a connecting member 15, and the connecting member 15 has a fitting protrusion 16 and a fitting groove 17 formed symmetrically on the front and back sides.

The protector 13 configured as above is
It is attached to the medical bag 1 in the following manner. The gripping body 14 is attached to each tubular member (each tube 4, 6, 7,
After wrapping it around the outer periphery of the connecting portion of the needle base 12), the fitting protrusion 16 of the connecting member 15 is fitted into the fitting groove 17 and fixed.

FIG. 3 shows a second embodiment of the protector.

Its structure consists of each tubular member (each tube 4, 6,
7. The gripper 19 of the needle base 12) is symmetrically attached with magic tape (registered trademark) 20, 20 on the front and back surfaces thereof.

The protector 18 having the above configuration has a grip body 19 attached to each tubular member (each tube 4, 6, 7,
After wrapping around the needle base 12), the magic tapes (registered trademark) 20, 20 are aligned and fixed together.

FIG. 4 shows a third embodiment of the protector.

21 is a shrink tube made of a flexible, heat-resistant material such as vinyl chloride resin.

The contraction tube 21 is fixed to the outer periphery of the connection point of each tubular member (each tube 4, 6, 7, needle base 12), and then is firmly fixed to the connection point by high-pressure steam sterilization.

As mentioned above, protectors 13, 18, 21
The medical bag 1 is made by wrapping (fixing) around the outer periphery of at least one connection point between a tubular member made of a soft synthetic resin and a tubular member made of a hard synthetic resin. Even after each tubular member (tube) is spirally wound, stored in a packaging container, and subjected to high-pressure steam sterilization, the load applied to the tubular member (tube) made of soft synthetic resin that is prone to bending is , it is relaxed and absorbed by the protector, so no creases occur.

(Effects of the invention) As described above, this invention eliminates the bending of each tubular member (tube) made of soft synthetic resin, so there is no need to worry about blood clots occurring during use, and smooth blood and plasma flow. It is a device that has excellent effects such as being able to transport items such as the like and carrying out efficient work.
