Self-exhausting, liquid-stopping and liquid-purifying infusion apparatus and safe infusion method thereof

Abstract

The invention relates to a self-exhausting, liquid-stopping and liquid-purifying infusion apparatus and a safe infusion method thereof. The infusion apparatus comprises a bottle stopper puncture device, an air inlet seat, a short infusion guide tube, an annular water-stop, a dripping bucket part, a long infusion guide tube, a flow regulator, a Y-shaped injection part, a liquid medicine filter and a disposable intravenous infusion needle, wherein the dripping bucket part comprises a dripping bucket upper cover, a dripping bucket and a dripping bucket base; an exhaust column is arranged on the dripping bucket upper cover; a liquid stop film is arranged on a spacer layer on the lower part of the dripping bucket; an air inlet hole is formed in the dripping bucket base. By adopting the self-exhausting, liquid-stopping and liquid-purifying infusion apparatus and the safe infusion method thereof disclosed by the invention, the functions of automatically exhausting, automatically stopping liquid and purifying liquid through an infusion tube are realized, and the labor intensity of medical personnel is lowered.

Description

technical field [0001] The invention relates to a sterile medical device for clinical infusion, in particular to a self-exhausting, liquid-stopping and purifiable liquid infusion device and a safe infusion method thereof. Background technique [0002] At present, the common infusion in the medical field is mainly composed of a bottle stopper piercer protective cap, a bottle stopper piercer, a short infusion catheter, a short exhaust catheter, an air filter, a dropper, a drip funnel, a long infusion catheter, and a long infusion catheter. , a drug filter and a disposable intravenous needle. When using an ordinary infusion set for infusion, the dripping funnel must be squeezed manually to introduce the medicinal liquid from the infusion bottle into the dripping funnel. When the medicinal liquid enters the dripping funnel, the medicinal liquid will easily press the gas in the dripping funnel into the long infusion catheter At the same time, due to the surface tension of the in...

AI Technical Summary

Problems solved by technology

When using an ordinary infusion set for infusion, the dripping funnel must be squeezed manually to introduce the medicinal liquid from the infusion bottle into the dripping funnel. When the medicinal liquid enters the dripping funnel, the medicinal liquid will easily press the gas in the dripping funnel into the long infusion catheter At the same time, due to the surface tension of the inner wall of the infusion tube, a small amount of air bubbles are easily adsorbed on the inner wall, and the removal process is difficult, cumbersome, and time-consuming. If the air bubbles cannot be removed well, the air bubbles will enter the patient's body with the liquid medicine and easily cause air embolism. wait for danger

At present, the way for medical staff to exhaust air before infusion to patients is: after the cork piercer is inserted into the infusion bottle, the dripping funnel is turned upside down, and the medicinal liquid enters the dripping funnel by squeezing the dripping funnel by hand. After the medicinal liquid in the dripping funnel reaches a certain amount, , put down the drip funnel, and remove most of the air bubbles as much as possible. For the adsorption of air bubbles on the inner wall, the medical staff needs to repeatedly flick the infusion catheter to drive the air bubbles into the drip funnel. The whole process is time-consuming, laborious, and cumbersome, which increases the work intensity of the medi
