Freestyle needleless precision control indwelling infusion system

Abstract

The invention relates to the technical field of medical instrument and specifically relates to a freestyle needleless precision control indwelling infusion system. The system comprises an infusion bagassembly which is composed of infusion long tubes connected in series, an infusion prolongation tube assembly and an indwelling infusion flexible tube assembly; the infusion bag assembly comprises anouter pressure box and an elastic infusion bag; the infusion prolongation tube assembly comprises an infusion prolongation tube and an accessory fine speed control valve, precision medicine tube, a positive pressure connector type needleless drug addition port and a Luer connector; the indwelling infusion flexible tube assembly comprises a positive pressure connector, a side hole steel needle, adirect current tube and an infusion hose connected to one end thereof; a side wall of the direct current tube extends slantly and is provided with an infusion branch tube; the direct current tube chamber is provided with medical silica gel pad; a stab-resistant locking assembly is installed on the side hole steel needle so that the needle tip is wrapped when the stab-resistant locking assembly getoff from the direct current tube. The invention fundamentally eliminates the risks existing in the existing infusion system, and provides the patient with a more reliable and safer infusion method, and at the same time ensures the safety of the medical staff and eliminates the risk of getting stabbed and infected.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a free-style steelless needle precision-controlled indwelling infusion system. Background technique [0002] The infusion set is a kind of device that treats liquid medicine or certain nutrients, blood products, etc., and supports nutrition into the body. The infusion set is mainly composed of a liquid storage bag, an infusion catheter, a flow adjustment unit, and a needle connected in sequence. . Current infusion sets are all made of disposable materials, which are convenient for clinical use and can reduce the risk of cross-infection. But the infusion of existing infusion set is to realize continuous infusion completely by the self-gravity of infusion product, and it needs to be suspended on the higher infusion stand. This method of relying on gravity infusion greatly restricts the patient's activities. Clinically, improper operation by a nurse or the patient's own re...

AI Technical Summary

Problems solved by technology

However, the infusion of existing infusion sets is completely dependent on the gravity of the infusion product itself to achieve continuous infusion, which needs to be hung on a higher infusion stand

This method of relying on gravity infusion greatly restricts the patient's activities. Clinically, improper operation by a nurse or the patient's own reasons may easily lead to clinical risks such as blood return or bulge. Especially in wartime or disaster emergency, it is easy to delay the infusion treatment and delay the most best time to treat

[0003] The steel needle and other puncture parts used in the traditional infusion set during the infusion process are very likely to cause harm such as needle rolling and swelling in clinical practice, and are easy to accidentally injure medical staff and collectors

At the same time, most of the existing infusion sets are made of PVC containing plasticizers. The infusion sets of this material have been proved to have potential carcinogenic risks. Therefore, those skilled in the art also urgently need a harmless infusion set to ensure the safety of patients. Infusion Safety
