Problems solved by technology

[0005] The liquid medicine storage uses the upper ribs inside the upper part and the lower ribs inside the lower part to control the buoyancy height and path of the float, but the liquid medicine storage needs to be composed of upper parts, lower parts, etc. The method of controlling the float by means of the upper and lower ribs cannot be used in a general drip reservoir, and the structure of the floating body and the sealing body of the float itself is complicated, and it needs to be designed corresponding to the size of the upper and lower ribs one by one, which is not only difficult to process high and limited

Abstract

The invention relates to a drip infusion fixer and a safety infusion water-sealing device. The device comprises a drip infusion fixer and a safety infusion water-sealing device. The drip infusion fixer is arranged in a drip storage cup, and the safety infusion water-sealing device floats above an injecta outlet. The safety infusion water-sealing device comprises a floating part and a blockage resisting part arranged below the floating part, wherein the floating part is provided with accommodation space and extends downwards to form a hollow connection part. The drip infusion fixer is provided with a positioning unit with a polygon shield, and is provided with a positioning hole at the centre. The floating part passes into the positioning hole through the connection part, and the tail end of the connection part is provided with an insertion hole. The blockage resisting part is fixed in the insertion hole through a convex part, and the bottom of the convex part is provided with a blockage resisting film.

Description

field of invention [0001] The present invention relates to an improvement of a drip infusion control device, especially to an improvement of a control device suitable for drip infusion sets, which can effectively block drips and air, and prevent blood backflow; and the control device is shaken or tilted or not , are not affected, but can ensure the anti-dripping effect. 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 sha...
