Indwelling subcutaneous infusion apparatus capable of being repeatedly utilized

Abstract

The invention relates to an indwelling subcutaneous infusion apparatus capable of being repeatedly utilized. The apparatus comprises an emitter which consists of an emitting seat, an emitting barrel body, a compression spring A, a compression spring B, a steel needle, an indwelling needle and a trigger, the top of the compression spring A and the top of the compression spring B are respectively fixed at positions in the emitting barrel body, which are close to the top and the middle, the bottom of the compression spring A is fixed on a position of a steel needle pedestal, which is close to the bottom, the bottom of the compression spring B is fixed on the bottom end face of the emitting seat, a clamping table is fixed at a position of one side of the steel needle pedestal, which is close to the top, the clamping table is clamped on a fixed bulge on the inner surface of the emitting barrel body, which is close to the top, the trigger consists of a button hinged outside the emitting seat, a spring piece fixed on the inner end face of the button and a check block with an inclined plane structure, the lower surface of the steel needle pedestal is fixedly connected with the connecting seat through a detachable manner, and a connecting rod is fixed at the bottom of the connecting seat. According to the apparatus, the structural design is ingenious, the operation is simple and convenient, and the pain that a patient suffers from can be effectively relieved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a reusable indwelling hypodermic infusion set. Background technique [0002] Clinically, there are many patients who need long-term subcutaneous infusion, such as insulin infusion for diabetic patients and hormone infusion for patients with hypohormonal decline. The existing methods are to connect one end of the infusion tube to the machine and the other end to a very thin steel needle for implantation. Subcutaneous, continuous or intermittent infusion of drugs, because these patients are generally not hospitalized, the daily care is not specialized in hospitals, and usually the patients still have to live normally, so it is not convenient to operate and use, and the steel needles under the skin are comfortable It is very poor, and it is easy to break. If a very thin steel needle breaks on the body, it will cause great harm, and the cost of taking out the steel needle is ...

[0002] Clinically, there are many patients who need long-term subcutaneous infusion, such as insulin infusion for diabetic patients and hormone infusion for patients with hypohormonal decline. The existing methods are to connect one end of the infusion tube to the machine and the other end to a very thin steel needle for implantation. Subcutaneous, continuous or intermittent infusion of drugs, because these patients are generally not hospitalized, the daily care is not specialized in hospitals, and usually the patients still have to live normally, so it is not convenient to operate and use, and the steel needles under the skin are comfortable It is very poor, and it is easy to break. If a very thin steel needle breaks on the body, it will cause great harm, and the cost of taking out the steel needle is also very high. The patient's psychological fear is very strong; A reusable indwelling hypodermic infusion set similar to an intravenous indwelling needle, which is simple and convenient, and can effectively relieve patients' pain, is very necessary
