阻止するためのクランプに関する。[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a tube clamp. More specifically, it relates to a clamp for temporarily blocking the flow of medicinal solutions, urine, blood, etc. by tightening tubes such as infusion sets, urine bags, femoral vein catheters, and arteriovenous shunts of blood circuits.

まう。<Prior art and its problems> A tube clamp consisting of a pair of plate-shaped pressing plates 1, an engaging part 2, and a support part 3 as shown in FIG. This type of tube clamp is used as a clamp, but when operating the clamp, the force applied to the finger pressing the clamp increases as the bending elasticity of the support part 3 increases, and the position of the tube approaches the engagement part 2. The larger it becomes. On the other hand, as shown in Fig. 7, the clamping force F of the clamp is expressed as the sum of the force f A applied to the support part 3 and the force f B applied to the engaging part 2, so the bending elasticity of the support part is greater than the force f A. If the size is too small, the press plate 1 will be pushed out and cause a clamping failure.
従つて締付力を大きくするためには支持部３の
曲げ弾性をより大きくする必要があり、またクラ
ンプの操作性を良くするためには（すなわち指に
加わる力を小さくするためには）、チユーブの位
置は操作者が自由に選択できるわけであるから、
支持部３の曲げ弾性をより小さくするかまたは押
圧板１をより長くする必要がある。 Therefore, in order to increase the clamping force, it is necessary to increase the bending elasticity of the support part 3, and in order to improve the operability of the clamp (that is, to reduce the force applied to the fingers), Since the position of the tube can be freely selected by the operator,
It is necessary to make the bending elasticity of the support part 3 smaller or to make the press plate 1 longer.
そして支持部３の曲げ弾性をより大きくするた
めには、曲げ弾性率の大きい材料を使用したり、
支持部３の断面積を大きくすればよいが、支持部
３の曲げ弾性をより大きくした場合、クランプの
操作に、より大きな力を必要とし問題であつた。 In order to further increase the bending elasticity of the support part 3, a material with a high bending elastic modulus may be used,
It is possible to increase the cross-sectional area of the support part 3, but if the bending elasticity of the support part 3 is increased, a larger force is required to operate the clamp, which is a problem.
このため支持部３の曲げ弾性を大きくし押圧板
１の長さを必要以上に長くすることによつて指先
に加わる力を低下させた例もあるが、寸法が大き
くなりすぎるので実用上問題があつた。 For this reason, there are examples of reducing the force applied to the fingertips by increasing the bending elasticity of the support part 3 and making the length of the press plate 1 longer than necessary, but this poses a practical problem because the dimensions become too large. It was hot.
本考案の目的は上記の問題点を解決することに

供することにある。 The purpose of the present invention is to solve the above-mentioned problems, and to provide a tube clamp that has a large clamping force and good operability (that is, can be operated with a small force).

完成した。<Means for Solving the Problems> As a result of intensive study in view of the above-mentioned problems, the inventor of the present application has designed the support portion to include an elastic portion that applies an opening force to the pressing plate, and a structure that is contained within this elastic portion. The present invention was completed by coming up with the idea of configuring the device with a supporting part provided.

なることがない。<Function> Since the tube clamp of the present invention is constructed as described above, the tightening force F when clamping the tube is the sum of the force f A applied to the support hinge 4 and the engaging portion 2 as shown in FIG. The force f A applied to the support hinge 4 acts to pull the hinge 4 to both sides. The plastic material used for the clamp is thin at the support hinge 4, and has sufficient flexibility in the bending direction, while being highly rigid in the stretching direction. Changes are extremely small. Therefore, even if the force f A is applied to the support hinge 4 when the tube is tightened, the press plate 1 will not be pushed apart and the clamp will not be defective.

る。 The pressing plate 1 is a tube tightening portion and is formed into a plate shape. A reinforcing part 6 is provided on the outside of the pressing plate 1 so that the pressing plate 1 will not be deformed even if the tightening force is increased, and a gripping part 7 is formed at the end of the reinforcing part 6 on the side of the engaging part 2. ing. Furthermore, on the inside of the pressing plate 1, a mountain-like protrusion 8 is provided on one side to improve clamping performance by reducing the clamping area of the tube, and on the other side, the tube does not protrude toward the support portion 3 side. A tube stop 9 is provided as shown in FIG.

比較的肉薄に形成されている。 The support part 3 has a support hinge 4 that supports the force that presses and spreads the pressure plate 1 caused by tightening the tube.
and an elastic hinge 5 that applies an opening force to the pressing plate 1. The support hinge 4 is formed thin so as to have sufficient flexibility in the bending direction and high rigidity in the stretching direction. Since it has the function of supporting the force that pushes and spreads the clamp, the bending elasticity can be reduced compared to conventional tube clamps of the same type, and therefore the press plate 1 can be opened and closed with appropriate flexibility. It is formed relatively thin.
