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 ...
