Puncture outfit dropping bucket

Abstract

The invention discloses a puncture outfit dropping bucket which comprises an upper dropping bucket (1) and a lower dropping bucket (4), wherein a cylindrical puncture outfit (14) is fixedly arranged on the upper part of the upper dropping bucket (1); the bottom end of the upper dropping bucket (1) is provided with an annular groove (7); the upper dropping bucket (1) is connected with the lower dropping bucket (4) through a fastener (10); a gasket (2) is pressed in the annular groove (7) through the lower dropping bucket (4); a through hole (12) is formed in the middle of the gasket (2); a medicine membrane (3) is arranged on the upper surface of the gasket (2); and a lower duct (6) is provided with a vent hole (13). The puncture outfit dropping bucket has the beneficial effects that air in the infusion set can be automatically removed, and the puncture outfit dropping bucket is easy to operate, safe and reliable; due to the arrangement of the medicine membrane, automatic liquid stop after the infusion is ended is realized; and by adopting the split dropping bucket, multiple parts in the traditional structure are integrated into a component, so that the processing difficulty is reduced, and the processing cost and raw material cost are reduced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a trocar dripper. Background technique [0002] The infusion set is a commonly used medical device. After the infusion set is inserted into the medicine bottle and before entering the human body for puncture, the drip funnel of the infusion set must be lowered down the catheter until the venous needle is filled with liquid medicine and no air bubbles remain, so as to prevent the air bubbles from being injected into the human body. This process is called venting. At present, the infusion sets used in medical institutions require the medical staff to manually exhaust, that is, the medical staff inverts the drip funnel or strangles the drip funnel with one hand, then pinches the drip funnel with the other hand and releases it, and uses the elasticity of the drip funnel to restore the drug absorption , repeat several times until the medicine liquid is stored to about hal...

AI Technical Summary

Problems solved by technology

However, the liquid-stopping drug passing through the membrane and the exhaust pipe of the dripping funnel need to be integrally formed with the dropping funnel, which is difficult to process, the fixing effect of the liquid-stopping drug passing through the membrane is poor, and the structure of the device is not stable, easily deformed and damaged, which affects its normal use.
