Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a clamp for clamping and closing a medical tube or the like.

(Prior Art) Conventionally, in the case of this type of clamp, as shown in FIGS. 4 and 5, the clamping portions A, A of opposing tubes formed in the center of the clamp are as follows:
Since the tube C was parallel or sloped upward, when the tube C was inserted into the section from the upper opening B and clamped at the lower end of the clamping parts A and A, the opposing clamping parts The pressing force with which the tube C is clamped by the clamping parts A and A is necessarily weak against the upper part of the tube because the clamping parts A and A are inclined upwardly due to the presence of the tube C as described above. The tube C clamped as shown in Fig. 5 is
In some cases, a hollow gap D was formed in the upper part of the tube C.

(Problem to be solved by the invention) Therefore, for example, if the tube C is connected to a blood bag or the like, blood will flow into the gap D, and therefore the effect of fastening the drain to the tube is not necessarily sufficient. It wasn't.

In view of the above-mentioned conventional technology, in order to complete the connection of the clamp to the tube and eliminate the void created inside the tube during fastening, the shape of the clamping part of the clamp for the tube was improved, and the flow path was improved. The aim is to completely eliminate the blockage.

(Means for Solving the Problems) The present invention for solving the above problems consists of tube clamps having elasticity, one end of which is open as an opening for tube insertion, and the other end of which forms a closed space. In a clamp that is provided with a stop part and can close the flow path of the tube when the tube is held between the stop parts, the interval between the closed ends of the stop part is wider than the interval between the tube insertion openings. , and the interval between the clamping portions is formed to be gradually tapered from the closed end toward the tube insertion opening.

(Function) As described above, the tube is inserted from above and the shape between the clamping parts to be fastened is a narrow trapezoid shape that gradually tapers upward. When fastened at the lower end between the clamping parts, the clamp has some elasticity, so the pressure from the tube causes the upper part of the clamping part to
Although the gap widens slightly and becomes somewhat parallel, it does not spread beyond the lower end, so the tube is completely fastened and fixed without creating any voids inside the tube, and blood, etc., can get inside the tube at the fastened part. There is no inflow.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

Fig. 1 is a front view showing the whole of the crevice according to the present invention, and Fig. 2 is a longitudinal sectional view of the same. In providing the clamping parts 1, 1 of the opposing tubes, the interval between the clamping parts 1, 1 is gradually tapered upward, that is, the clamping parts 1, 1 of the opposing tubes are formed so as to gradually taper upward. The width 1a of the lower end interval between the stopper parts 1, 1 is wider than the upper ends of the stopper parts 1, 1 of the opposing tubes, that is, the tube insertion part 1b, and the tube 2 is When installing it between the clamping parts 1, 1, as shown in Fig. 3,
Insert the tube 2 through the opening 3 provided at the upper end of the clamp, then insert the tube 2 into the clamping part 1,
Insert the tube through the tube insertion part 1b between 1, push it to the lower end, and attach it between the clamping parts 1 and 1.
When the tube 2 is attached, the clamp, which is flexible, has some elasticity, so if the gap between the clamping parts 1 and 1 is slightly enlarged upward, the tube 2 will be completely fastened and fixed to the clamp, and at this time, the clamping part will be tightened and fixed. As mentioned above, the parts 1 and 1 are directed upward toward each other and the distance between them is tapered, so that due to this shape, the tube 2 does not have a gap when fastened, as shown in FIG. 3, as in the conventional case. It never happens.

(Effect of the invention) The present invention having the above configuration differs from the conventional tube in which the spacing between the clamping parts is parallel or opens upward, and is instead opened downward, that is, the spacing between the parts is opposite to each other. Since the spacing between the lower ends of the clamping part is wider than the tube insertion part at the upper end, even when the tube is fastened at the lower end of insertion, even if it opens slightly upward due to the elasticity of the gripper itself, the upper end will be wider than the tube insertion part at the upper end. In order to prevent the tube from becoming wider, the tube is inserted and fastened from a place having a predetermined composition ratio, and the tube is completely occluded without creating any void inside the tube, so that, for example, the inflow of blood, etc. By simply having a small configuration of only the tube clamping part, the desired tube fastening effect can be easily obtained, and since the clamp is integrally molded with resin etc., it can be easily molded as before. In this way, the tube can be completely fastened by simple molding without requiring any special process operations compared to the conventional method.
