Problems solved by technology

Assuming that the injection rate is set to 1 unit / hour, the insulin pump will slowly and uniformly push the piston forward by 0.1mm within 1 hour. Since the distance of the piston advance is too short, it needs to maintain a constant speed. This requirement makes the electromechanical transmission part of the insulin pump extremely precise and Complicated and costly

Abstract

The invention discloses a self-destructive precision infusion device. The device comprises an infusion tube filled with medical liquid, an infusion needle arranged at the tail end of the infusion tubeand an injection mechanism arranged at the head end of the infusion tube; the injection mechanism comprises a piston which is inserted at the head end of the infusion tube and used for pushing the medicine liquid for feeding, a blade arranged at the end, away from the medical liquid, of the piston and a driving mechanism used for pulling the infusion tube separated by the blade for feeding; the blade is fastened with the driving mechanism and extends out of the infusion tube. Through the structural design and the arrangement of the infusion tube, the cross-sectional area of the piston can beeffectively reduced, the stroke of the piston can be effectively increased, and the liquid medicine injection precision can be effectively improved; in addition, through the arrangement of the injection mechanism, the product structure is greatly simplified, the injection precision is improved, and meanwhile the production cost of products is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a self-destruct precision transfusion device. Background technique [0002] In the medical field, a typical representative of portable high-precision human body liquid medicine infusion is an insulin pump, which is used to treat diabetic patients. Insulin is measured in "units", and each cc (or mL) is divided into 100 units, assuming that the concentration is the standard U-100. In this measurement method, one unit is equivalent to 10 μL. Usually, each drug reservoir stores 3ml of insulin, that is, 300 units, and looks like a short and thick small syringe. The total stroke of the drug reservoir piston is about 3cm, and the inner diameter is about 12mm. Assuming that the injection rate is set to 1 unit / hour, the insulin pump will slowly and uniformly push the piston forward by 0.1mm within 1 hour. Since the distance of the piston advance is too short, it needs to maintain...
