Disposable sensitive blood return infusion apparatus for children

Abstract

The invention relates to a disposable sensitive blood return infusion apparatus for children. The disposable sensitive blood return infusion apparatus for the children comprises a bottle insertion pin, a liquid stopping card, a drip bottle, a multifunctional micro-adjuster, a sensitive blood return device and an intravenous needle; a bottom medical liquid outlet inside the drip bottle is provided with a medical liquid precise filter cap which can automatically discharge bubbles; the medical liquid precise filter cap is in a cylindrical shape or a bell jar shape. According to the scheme of the disposable sensitive blood return infusion apparatus for the children, small particles are prevented from blocking a filter screen, gas inside a large infusion bag is avoided from entering an infusion tube and discharged gas is smoothly discharged through a liquid blocking transparent film when the intravenous needle discharges gas inside the medical liquid, outflowing medical liquid is stored inside an automatic liquid blocking protection cover, the workload of operators is reduced, and environmental sanitary pollution is avoided; the intravenous needle is prevented from being separated from the infusion apparatus, capacity is expanded and pressure is reduced through the sensitive blood return device in the infusion apparatus, the success rate of first puncture is guaranteed, physical and mental labor of medical operators can be greatly saved, the working benefit is improved, and a patient can be avoided from pain of puncture for a plurality of times.

Description

technical field [0001] The invention relates to a medical device, in particular to a disposable precise and sensitive blood return infusion set for children. Background technique [0002] The existing disposable infusion set, especially the one-time use infusion set for children, when performing clinical infusion, when performing infusion treatment for patients who need intravenous injection of antibiotics and other drugs, medical personnel need to use it first when performing infusion. The syringe dilutes the powdered medicine in the medicine bottle, and then injects the diluted medicine solution into the liquid storage bag. The diluted medicine solution cannot be fully diluted, resulting in some fine particles beyond the safe diameter entering the patient's body , especially for infants or children, due to the thinner veins, these fine particles will cause serious damage when they enter their bodies. The precision filters currently on the market have a small filtration are...

[0002] The existing disposable infusion set, especially the one-time use infusion set for children, when performing clinical infusion, when performing infusion treatment for patients who need intravenous injection of antibiotics and other drugs, medical personnel need to use it first when performing infusion. The syringe dilutes the powdered medicine in the medicine bottle, and then injects the diluted medicine solution into the liquid storage bag. The diluted medicine solution cannot be fully diluted, resulting in some fine particles beyond the safe diameter entering the patient's body , especially for infants or children, due to the thinner veins, these fine particles will cause serious damage when they enter their bodies. The precision filters currently on the market have a small filtration area, which is easy to block during the infusion process and cannot be drained. Phenomena such as gas, especially some precision filters design vent holes on the filter, which will affect the volatilization of the drug effect and reduce the function of the liquid medicine. The liquid medicine flows out from the needle tip of the vein, which pollutes the environment and sanitation
