Description

Umbrella-shaped anti-falling infusion joint

Technical Field

The utility model relates to the technical field of medical treatment, specifically an umbelliform anticreep infusion connects.

Background

The infusion solution or large-volume injection solution is large-dose injection solution which is infused into a human body by intravenous drip, and the dose is more than 100ml at one time. It is a branch of injection, usually packaged in glass or plastic infusion bottles or bags, and contains no bacteriostatic agent. When in use, the dropping speed is adjusted by the infusion apparatus, and the medicine is continuously and stably infused into the body.

The quality requirement of infusion is basically consistent with that of injection, but the injection quantity of the product is larger, so the requirements of sterility, pyrogen-free property and clarity are more strict. Furthermore, the following quality requirements should also be noted: firstly, on the basis of ensuring the curative effect and the product stability, the pH value is close to the pH value of human blood, and acid-base poisoning can be caused by overhigh or overlow pH value; ② the osmotic pressure should be isotonic or hypertonic; thirdly, no bacteriostatic agent is added in the transfusion, and the quality is stable in the storage process; fourthly, the medicine has no toxic and side effect, can not have foreign protein and antihypertensive substance which cause anaphylactic reaction, can not cause abnormal change of hemogram after being transfused into human bodies, and can not damage liver and kidney functions, and the like.

Venous transfusion is the most common treatment mode clinically, however, generally the transfer line is in the institute during direct syringe needle through its pipeline end inserts infusion bag or infusion bottle, lack the fixed measure, when the patient appears rocking or dragging at the infusion in-process, lead to the terminal syringe needle of infusion to deviate from easily, lead to the infusion to break off, the syringe needle is also contaminated easily, the syringe needle after the pollution is inserted back can pollute the infusion, infusion safety risk has been increased, nurse's work load has also been increased, an umbelliform anticreep infusion connects has consequently been designed.
