Freestyle needleless precision control indwelling infusion system

Abstract

The present invention relates to the technical field of medical devices, in particular to a free-type steelless needle precise control indwelling infusion system, comprising an infusion bag assembly connected in series by an infusion extension tube, an infusion extension tube assembly and an indwelling infusion hose assembly; The infusion bag assembly includes an external pressure box and an elastic infusion bag; the infusion extension tube assembly includes an infusion extension tube and an attached fine speed control valve, a precision drug filter, a positive pressure connector type needle-free drug feeding port and a Luer connector; The tube assembly includes a positive pressure connector, a steel needle with a side hole, a direct-current tube and an infusion hose connected at one end. The side wall of the direct-current tube extends obliquely with an infusion branch tube. The anti-stab locking component is provided on it to wrap the needle tip when it is separated from the direct-current tube; the present invention fundamentally eliminates the risks existing in the existing infusion system, provides patients with a more reliable and safer infusion method, and ensures that medical staff The operation is safe, eliminating the risk of puncture injuries and infection.

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
