Anti-extrusion drip transfusion safety control device

Abstract

The invention relates to an anti-extrusion drip transfusion safety control device which mainly comprises a floating detent plug device and a drip storage cup, wherein the floating detent plug device is arranged in the drip storage cup and floats above a liquid outlet of the drip storage cup; the floating detent plug device floats up and down under the action of floating power and can block the liquid outlet of the drip storage cup when the liquid level falls so as to stop the liquid; and an internal support sleeve is arranged in the drip storage cup to prevent the pressed deformation of the drip storage cup, thereby avoiding the situation that the floating detent plug device is obstructed when floating up and down.

Description

technical field [0001] The invention relates to an anti-squeeze infusion safety control device, especially a control device suitable for infusion sets that can effectively block drips and air, prevent blood from flowing back, and prevent loss of function when squeezed by external forces. . Background technique [0002] The existing drip syringe control device, in order to solve the problem of avoiding air injection into the human body when the injection is about to be injected, such as the Chinese Patent Publication No. CN2601096, discloses a piston for dripping, wherein the drip plug is placed in the bottle as a whole. In the middle, and the top of the drip plug is a cavity so that the drip plug floats on the top of the drip liquid. When the drip liquid is about to be used up, the drip stopper drops to the mouth of the bottle with the liquid level and is sealed with the bottle wall by the shape of the drip stopper. However, since the drip stopper is smaller than the inner ...

AI Technical Summary

Problems solved by technology

When the drip liquid is about to be used up, the drip stopper drops to the bottle mouth with the liquid level and is sealed with the bottle wall by the shape of the drip stopper. However, since the drip stopper is relatively small compared to the inner diameter of the drip bottle, when the drip bottle is shaken under force The drip stopper will roll arbitrarily in the bottle and cannot effectively seal the bottle wall to achieve the stopper effect

[0003] Another example is the Chinese patent announcement number CN2654146, which discloses a control device for drip syringes, which is mainly a floating body container with a hollow cylindrical body. Floating on the surface of the liquid, but due to the poor design of the floating body container, in order to maintain the continuous operation of the drip syringe, it is necessary to set an additional water hole at the appropriate position on the lower edge of the floating plate to ensure that the floating body container will not sink into the liquid due to overflow

[0004] The suction cup at the lower end of the floating container needs to follow the suction of the drainage to make the concave suction cup form a spherical shape and then close the outlet of the drip storage cup. It cannot directly absorb the outlet that is pressed tightly on the bottom of the drip storage cup
