Clamping device for an operation

A technology of clamping device and protrusion, which is applied in the direction of hypodermic injection equipment, flow control, non-electric variable control, etc., can solve the clamping range (the clamping range is narrowed, the inner cavity of the tube cannot be fully blocked, and the blocking is not enough). Sufficient and other issues

Example Embodiment

[0041] Hereinafter, the present invention will be specifically described with reference to the drawings, but the present invention is not limited to the specific examples described below. Fig. 1 is a side view showing the clamping device of the present invention. In FIG. 1, the clamping device of the present invention connects the upper end portion 11, the bent portion 14 provided with the tube insertion hole 15, the bottom portion 12, and the rising end portion 13 provided with the tube insertion hole 16 at the front end of the upper end portion 11. It has a locking protrusion 25. On the other hand, on the front end side of the rising end 13, there is a locking groove 18 on the inner side, and the locking groove 18 and the locking protrusion 25 are detachably engaged with each other to form an annular body. Inside the annular body, there is a first protrusion 21 extending downward on the lower surface of the upper end portion 11, and a second protrusion 22 facing the first protru...

Abstract

The invention provides a well-qualified clamping device which presses, with high operational efficiency, a clamping tube in one operation in a manner of preventing the tube from transverse deviation, avoids deviation at the time of engagement between a locking projecting portion and a locking groove portion, and improves rate of finished products and shortens finishing period by reducing cost of moulds so as to realize reduction of the cost. In the clamping device of the invention, inner sides of an upper end (11) and a bottom (12) include a first projecting portion (21) and a second projecting portion that are opposite to each other, and also includes a downwards-extending pressing portion (23) nearby, a front end (24) of the pressing portion (23) is formed with square or quadrate projections (23a), (23b) in a crotched manner. Further, the bottom (12) in an extending direction of the pressing portion (23) includes a incision portion (17).

Description

technical field [0001] The present invention relates to a clamping device capable of clamping a tube in one operation, correcting and preventing the lateral deviation of the tube while clamping the tube, and preventing the clamping protrusion and the clamping groove from The offset of the two locking parts at the same time is the so-called one-time operation clamping device. Background technique [0002] The conventional clamping device is used as a fluid switching device for stopping or flowing a fluid such as blood or medical solution flowing in a tube such as a blood circuit tube or a blood transfusion tube. Especially in the blood circuit, since the clamping device is used for various purposes depending on the type of the tube diameter, the clamping device produces a tube deviation during use, and when the tube is blocked, it is extruded from the clamping part, so that the clamping device Insufficient occlusion. In addition, as the engagement protrusion and the engagem...
