JPS599643Y2 - Infusion bag - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to an improvement of an infusion bag to which an infusion set is connected.

Conventionally, infusion bags containing medicinal solutions such as glucose and Ringer's have been widely used, but when using this infusion bag, usually a separate infusion set is removed from the packaging bag, and the introducer needle of the set is connected to the infusion bag. It is necessary to insert it into the section.

Therefore, not only is the operation troublesome, but there is also a risk of contamination with microorganisms, foreign substances, pyrogen, etc.

For this reason, in the past, for example,
As proposed in Japanese Patent No. 0156, there are also cases in which an infusion bag and an infusion set are integrally connected.

However, since this device is made by bending the head of the connecting tube inside the bag to connect the bag and the set, especially when the bag is filled with a medicinal solution,
It is difficult to bend the head of the connecting tube, and there is a risk that fine cut pieces may get mixed into the chemical solution.

The present invention was proposed as a result of studies to solve these conventional drawbacks, and its basic feature is that the infusion set is connected to the communication part of the infusion bag via a communication mechanism.

Hereinafter, a specific embodiment of the present invention will be described with reference to the accompanying drawings. First, in FIG. A drip tube 3 and a clamp 4 are attached to a tube 7 made of Hewei resin, and an injection needle 6 is attached to the tip of the tube 7 via an octopus tube 5.

Such an infusion set 2 is connected to a communication portion 8 of an infusion bag 1 via a communication piece 9.

That is, as shown in FIG. 3, supports 10.11 are fixed at intervals within the communication portion 8, and the opening side end 9a of the communication piece 9 is fixed to the upper support 10. Further, the upper end of the tube 7 is fixed to the lower support 11.

The communication piece 9 is made of a relatively hard synthetic resin, and has a thin section 9b formed in the middle thereof, which can be easily cut by bending the sealed end 9C. There is.

It should be noted that the communication mechanism described above is an example of the present invention, and it goes without saying that the structure is not limited to the detailed structure or what is shown in the drawings.

Furthermore, in the embodiment shown in FIG. 1, the infusion set 2 is integrally connected to the infusion bag 1, but in the present invention, as shown in FIG. You may also do so.

This quick connector 20 does not need to have a special structure, and a conventionally known one is sufficient.

According to this embodiment, for example, when a patient cannot use a normal infusion set, the normal infusion set is removed at the quick connector 20 and the introduction needle of another infusion set is inserted into the introduction port 21 of the infusion bag 1. It is possible and convenient.

According to the present invention as described above, the infusion set is connected to the communication part of the infusion bag through the communication piece, so that when infusing the infusion, all that is required is to fold the communication piece 9 from above the communication part 8. The bag and the set can be easily communicated, and the communication piece 9 does not come into contact with the outside air, so it is extremely user-friendly.

Further, according to the present invention, the communicating piece 9 is located between the supports 10jl, and the sealed end 9C faces the infusion set tube 7 side, so that the cut piece of the communicating piece 9 is prevented from entering the tube 7. This can be prevented by the infusion set side supporter 11, and since the communicating piece 9 is supported by the upper supporter on the infusion bag side, the diameter of the communicating piece 9 can be easily changed within the range of the inner diameter of the communicating part 8. It is possible to do so.

Moreover, since the communication piece 9 is supported by the support body 10, when cutting the communication piece 9 at the thin wall portion 9b, the support body 10 is held and the communication piece 9 is cut with a finger or the like from the outside of the communication portion 8.
This has the advantage that it can be easily folded by simply pressing and bending the sealed end 9C.
