Safety vein infusion control device

Abstract

The invention discloses a safety vein infusion control device which mainly comprises a floating stop plug device and a drop storage cup, wherein the floating stop plug device is arranged in the drop storage cup and floated above an injection outlet of the drop storage cup, the floating stop plug device comprises a hollow floater and a water stop cover unit arranged below the floater, a hollow connector extending downwards is arranged in the floater, an annular groove is formed on the periphery of the connector, a jack is arranged at the lower end of the connector, the water stop cover unit isinserted into the jack through a connecting lug at the top end, the water stop cover unit is provided with a containing space and a stop plug film on the bottom, and the stop plug film can cover the injection outlet of the drop storage cup so as to be stuck on a stop plug.

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...

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
