Infusion system without steel needle

Abstract

The invention provides an infusion system without a steel needle, and relates to the technical field of medical instruments. The infusion system comprises an infusion bottle, a butt joint device and an infusion catheter, wherein the bottle opening of the infusion bottle is movably connected with one end of the infusion catheter through the butt joint device, an infusion connector is arranged at the other end of the infusion catheter, and a reinforcing device is further arranged between the infusion bottle and one end of the infusion catheter; the reinforcing device comprises a lower sleeve opening and an upper buckle, the lower sleeve opening is of a hollow tubular structure, the upper buckle is a circular ring with a notch, and one end of the lower sleeve opening is fixedly arranged on the infusion catheter; the upper buckle is movably arranged at the other end of the lower sleeve opening, and the infusion catheter is further provided with a liquid stopping buckle and a needle-free medicine adding opening. The system has the advantage that the puncture injury of a puncture outfit to a nurse or a patient can be eliminated, and secondary injury caused by puncture debris generated bythe puncture outfit to the patient can be eliminated.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a needleless infusion system. Background technique [0002] As the most commonly used equipment for medical care, infusion set is a key channel between the patient's vein and the therapeutic liquid. Especially in China, its use range is extremely wide. A good infusion set can help the patient recover as soon as possible, otherwise it will cause secondary damage and aggravate the patient's condition. Although the infusion sets circulating on the market are various in variety and have different functions, they are consistent in main structure. The infusion bottle (bag) is connected with the infusion pipeline by the puncture device, and the medicinal liquid is infused into the patient's body to treat the disease. This main structure has not changed since the infusion set was born, and its disadvantages are increasingly prominent in the clinical use process. First of all, w...

Problems solved by technology

In this process, in order to facilitate the puncture, the surface of the puncture device is made smooth and sharp, which is very easy for medical staff to cause injury during operation. At the same time, puncture debris will inevitably be generated during the puncture process. The puncture debris will enter the infusion container and mix with the liquid medicine. Cause secondary injury or even serious harm to human body

In recent years, although relevant patents have optimized trocars or connecting devices to reduce their disadvantages, such as adopting blunt puncture structures and adding puncture protection devices, etc., they have not fundamentally eliminated the use of trocars and solved the above problems
