It is provided with an upper infusion tube on the upper end of the outer casing of the drip pot, and a puncture needle is arranged on the upper end of the upper infusion tube. There is an elastic valve cylinder inside the shell, and the inner and upper end of the elastic valve cylinder is provided with a drop control tube for observing the dripping speed of the infusion, the upper middle part of the elastic valve cylinder is provided with an elastic valve seat, and the lower end of the elastic valve seat is provided with a conical gear-shaped elastic spring. Valve, the lower part of the elastic valve cylinder is provided with an upper cross base, the upper cross base is provided with a middle film cross, and the lower end of the middle film cross is provided with a lower film cross, the elastic valve seat, the upper, middle and lower film crosses are combined with the elastic valve cylinder to form an elastic Filtration and purification combination, the lower end of the drip pot is provided with a lower infusion tube, the lower end of the lower infusion tube is provided with an infusion connector, and the lower end of the infusion tube connector is provided with a scalp vein needle. The invention has simple structure, ingenious design, and low processing and production costs , It is safe to use and the effect is obvious.

Description

Technical field [0001] The invention relates to an intravenous infusion set, specifically an intravenous infusion set provided with a spring-elastic double valve, an elastic rubber membrane control device and a purification filter. Background technique [0002] Intravenous infusion set is an important equipment for clinical medical treatment, which plays a major role in the treatment and rehabilitation of patients. Due to the defects of structure and design, the intravenous infusion set currently in use has the following shortcomings in clinical use. One is the lateral position or infusion of patients. When the affected limb is raised, it is easy to cause blood reflux in the infusion needle; second, during infusion, if the medicine in the infusion bottle is dripping, if the infusion bottle is not replaced in time, air or blood will enter the dropper. When the infusion bottle is replaced and the infusion is continued, the air in the infusion tube will enter the human blood vessels...

Problems solved by technology

[0002] Intravenous infusion set is an important equipment for clinical medical treatment, which plays a major role in the treatment and rehabilitation of patients. Due to the defects of structure and design, the current intravenous infusion set has the following shortcomings in clinical use. When the affected limb is raised, it is easy to cause blood reflux in the infusion needle; the second is that during infusion, if the liquid medicine in the infusion bottle drips and the infusion bottle is not replaced in time, the dropper will enter the air or the blood will return. When the infusion bottle is replaced and the infusion is continued, the air in the infusion tube will enter the blood vessels of the human body, which will adversely affect the recovery of the human body. When the nurse adds medicine to the infusion bottle first, it is inevitable that other drug impurities, bacteria, and viruses will enter the infusion bottle and enter the human body through the infusion set, which will also cause harm to the patient.
