[Problem to be solved by the invention]

However, in the method of closing the liquid sampling tube of a medical bag described in (2), it is troublesome to make a loop in the liquid sampling tube in advance, and tying this loop requires more force than expected, so it is difficult to tie it at the right time. If you do not do this, you will not be able to bleed air from the medical bag, and it will also look bad.

The room closing method (2) requires a heat or high-frequency sealer, which takes up space in a narrow clean bench, and changes the air flow inside the clean bench, resulting in undesirable results in terms of hygiene management.

The method of closing the chamber (2) requires placing an aluminum ring over the liquid sampling tube and caulking the aluminum ring using a bench or the like, which is inefficient in terms of workability.

In the chamber closing method (2), it is not possible to attach a clamp 1゛ or l'' to the liquid sampling tube 4 in advance, and it is necessary to attach a clamp l° or l'' to the liquid sampling tube 4 when closing the liquid sampling tube 4. troublesome. Also, these clamps 1°
and l'', both of which connect the liquid collection tube 4 to the protrusions 9 and 1.
Since the mechanism is to close the liquid sampling tube 4 by clamping it at 0, if tension is applied to the liquid sampling tube 4, the clamps 1° and 1'' will shift, resulting in insufficient closing of the liquid sampling tube 4. There is a possibility that this will happen.

The present invention has been made in view of the above circumstances, and provides a clamp that can be attached to a tube in advance, is easy to work with, can completely close the tube, and does not come off from the tube. [Means for Solving the Problems] In order to solve the above problems, the clamp of the present invention is a clamp that can close the flow path of the tube by closing the tube with pressure. The clamp has a tube insertion hole, is capable of clamping the tube inserted into the tube insertion hole and closing the tube, and is a fixture capable of clamping the tube and fixing the tube in a closed state. The device includes a pair of clamping bodies equipped with a mechanism, and a connecting portion that connects the pair of clamping bodies in an openable and closable manner.

Further, when tube press-closing protrusions are respectively provided on opposing surfaces of the pair of clamping bodies when the tube is press-closed by the clamp, the layer tube is completely closed.

(Function) According to the clamp configured as described above, the tube is passed through the tube insertion hole in advance, and when necessary, the tube is clamped by a pair of clamping bodies that are connected at the connecting part so as to be openable and closable. By fixing the pair of clamping bodies in this state with the fixing mechanism, the tube is closed and the clamp does not come off from the tube.Also, when the tube is closed, the tube pressure is applied to the opposing surfaces of the pair of clamping bodies. When necessary, use clamps each equipped with a closing protrusion to pinch the tube to close it and secure it with the fixing mechanism.
The tube is further closed, and even if a force is applied to pull the clamp out of the tube, the protrusion still prevents the clamp from coming off the tube.

(Example) Hereinafter, an example of the present invention will be described in detail based on FIGS. 1 to 7.

FIG. 1 is a perspective view of the clamp of the present invention in a fixed state;
FIG. 2 is a perspective view of the clamp in an open state, and FIG. 3 is a plan view of the clamp. In the drawings, reference numeral 1 indicates a clamp, and a clamp 1 is provided with tube insertion holes 2a and 3a, respectively, and a liquid collection tube (tube) 4 of a medical bag inserted into the tube insertion holes 28 and 3a. A pair of clamping bodies 2 that can be clamped and closed
and 3, a fixing mechanism 5 provided on the pair of clamping bodies 2 and 3 and capable of fixing the pair of clamping bodies 2 and 3 in a state where the liquid collection tube 4 is clamped and closed, and the pair of clamping bodies 2 and 3 in an openable and closable manner.

The pair of holding bodies 2 and 3 are made of synthetic resin or the like and are rectangular plates. These one clamping bodies 2 and 3 are connected by the connecting part 6 so as to be openable and closable, as described above. The connecting portion 6 of this pair of clamping bodies 2 and 3
As shown in FIG. 1, the side proximal end portion is cut out into a U-shape as a whole. The notches A and B are provided with a hole D, stopper portions 2b and 3b, and tube insertion holes 2a and 3a, respectively, in this order from the connecting portion 6 side.

This hole is designed to prevent the liquid collection tube 4, which is folded in half, from shifting from the approximate center of the width of the clamping bodies 2 and 3 when the pair of clamping bodies 2 and 3 of the clamp 1 are fixed by the fixing mechanism. It is set up for the purpose of The stopper portions 2b and 3b are for closing the liquid collection tube 4 folded in two. The tube insertion holes 2a and 3a are
When the liquid sampling tube 4 is passed through this, these tube insertion holes 2a and 3a are inserted to prevent the clamp 1 from slipping down.
The cross-sectional area of the tube 4 is approximately the same as that of the liquid collection tube 4. Tube holding parts 2c and 3c are provided at the tips of the pair of clamping bodies 2 and 3, respectively, so that when the liquid collection tube 4 is fixed with the clamp 1, no extra force is applied to the clamp 1. There is no such thing.

As shown in FIG. 3, the fixing mechanism 5 consists of a female part 7 provided on both sides of the holding body 2 and a male part 8 provided on both sides of the holding body 3. By inserting the male part 8 into the female part 7 of the clamping body 2, these pair of clamping bodies 2 and 3 are fixed. If the clamping bodies 2 and 3 have some elasticity, by expanding the female part 8 of the clamping body 2 even after fixing, the clamping body 3 can be removed from the female part 7 of the clamping body 2. It is possible to remove the male part 8.

Next, a case will be described in which the clamp 1 having the above configuration is used in the liquid sampling tube 4 of a medical bag.

First, the liquid sampling tube 4 is passed through the tube insertion holes 2a and 3a of the pair of clamping bodies 2 and 3 of the clamp 1, respectively. Since the tube insertion holes 2a and 3a have substantially the same cross-sectional area as the liquid sampling tube 4, the clamp 1 will not slip off from the liquid sampling tube 4.

Next, after injecting the infusion into the medical bag, the liquid collection tube 4
With the medical bag facing upward, compress the medical bag by hand and remove the air inside the medical bag. After the interface between the air and the infusion agent passes through the clamp 1 in the liquid sampling tube 4, the pair of clamping bodies 2 and 3 of the clamp 1 are bent in the direction of the arrow C in FIG. 2 around the connecting portion 6.

The liquid sampling tube 4 does not shift from side to side due to the hole.
It is bent while remaining at the center, and as shown in FIG. 4, the male part 8 of the clamping body 3 is inserted into the female part 7 of the clamping body 2, and the pair of clamping bodies 2 and 3 are fixed.

By this operation, the liquid sampling tube 4 is folded in half as shown in FIG.
The chamber is closed by stopper parts 2b and 3b. Further, since the liquid sampling tube 4 is held within the tube holding parts 2c and 3c, the clamp 1 is fixed so that no unnecessary force is applied to the clamp 1.

In addition, the liquid sampling tube 4 closed by the clamp 1 is
Since the chamber is completely closed, as shown in Figure 6, unnecessary liquid collection tubes 4 with bottle needles etc. can be cut off. FIG. 7, which is convenient, shows another embodiment of the present invention. It is provided with protrusions 9 and 10 for use, and the protrusions 9 and 10 make it possible to caulk the liquid collection tube.
Note that even when the liquid sampling tube 4 is completely closed, the clamp 1 cannot be removed from the liquid sampling tube 4. That is, since the liquid sampling tube 4 is stopped by the stoppers 2b and 3b and further caulked by the protrusions 9 and 10, the liquid sampling tube 4 is only extended by external force and does not come off from the clamp 1 at all.

〔Effect of the invention〕

As described in detail above, the clamp of the present invention is a clamp that can close the flow path of the tube by compressing the tube, and the clamp has a tube insertion hole and a tube insertion hole. a pair of clamping bodies that are capable of clamping the inserted tube and compressing and closing the tube, and that are equipped with a fixing mechanism capable of clamping the tube and fixing the tube in a compressed and closed state; and the pair of clamping bodies. The duplex is equipped with a connecting part that connects the body so that it can be opened and closed, and the tube is passed through the tube insertion hole in advance, and when necessary, the duplex can be closed by being clamped by a pair of clamping bodies that are connected to the connecting part so that it can be opened and closed. However, by fixing the pair of clamping bodies in this state with the fixing mechanism, the tube is closed and the clamp does not come off from the tube. Therefore, this clamp can be attached to the tube in advance, and the tube can be closed with a single touch.The clamp is clamped and closed with the tube in a bent state, making it easy to work with and has a good appearance. The tube can be completely closed, and even if a strong force is applied to pull the clamp out of the tube, the tube will only extend, and the clamp will not be removed from the tube.

In addition, by using a clamp in which a pair of clamping bodies are provided with protrusions for tube compression and closing on opposing surfaces, in addition to the above-mentioned effects, the tube can be clamped and fixed when necessary. When the pair of clamping bodies are fixed by the mechanism, the tube is more strongly closed, and even if a strong force is applied to pull out the clamp from the tube, the tube only stretches, and the protrusion makes it even harder to remove the clamp from the tube. has the effect of
