Abstract

The invention relates to a disposable retaining needle type infusion apparatus, which comprises a bottle threading needle with an air filter, a drip bucket, a flow adjuster and a medical liquid filter connected in series by infusion catheters; the lower end of the medicinal liquid filer is connected with a medicating tee component; and the medicating tee component is connected with a vein retaining needle through a siphonium. The vein retaining needle comprises a retaining needle sleeve, a sleeve seat, a puncture needle tube and the siphonium; the rear end of the sleeve is connected with the sleeve seat; the inside of the sleeve seat is provided with a sealing plug; the puncture needle tube is hermetically inserted through the sealing plug and runs through the retaining needle sleeve and the sleeve seat; and the sleeve seat is laterally provided with a siphonium joint which is connected with the medicating tee component through the siphonium. The disposable retaining needle type infusion apparatus reasonably combines a traditional infusion apparatus and the vein retaining needle, is disposable, has a simple structure, reliable connection and convenient operation and use, has the characteristics of the vein retaining needle and is an ideal disposable retaining needle type infusion apparatus.

Description

technical field [0001] The invention relates to a medical device, in particular to a disposable indwelling needle infusion set. Background technique [0002] We know that a disposable infusion set is a commonly used medical device, which generally includes a bottle piercing needle, a drip funnel, a liquid flow regulator, a liquid medicine filter, and a connector, and they are connected in series by an infusion catheter. The infusion flow is regulated and controlled by a liquid flow regulator. The liquid medicine filter is generally composed of upper and lower shells and a microporous membrane purification layer. The microporous membrane purification layer is sandwiched between the funnel-shaped upper and lower shells. The liquid medicine is filtered and purified. During operation and use, a puncture infusion steel needle is connected through the connector and the connecting pipe. Since the tough puncture infusion steel needle is inserted into the patient's venous blood ves...
