Abstract

The invention relates to improvement of a safe drip transfusion control device, which mainly consists of a floating stopper device and a drip storage cup. The floating stopper device is arranged into the drip storage cup, floats above an injection outlet of the drip storage cup and comprises a floating piece, a floating body seat and a stopper ring, the floating body seat is arranged below the floating piece, the stopper ring is arranged below the floating body seat, the upside of the floating body is provided with a liquid-receiving groove is arranged above the floating body and is is inserted into a jack at the upper end of the floating body seat by an extension piece below the groove bottom of the liquid-receiving groove, the floating body seat is sleeved into the stopper ring by using a sleeve interface at the lower end, and the stopper ring has a thin film sufficient to cover the injection outlet of the drip storage cup and ensure the joint of the stopper.

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...
