Abstract

The invention discloses a medical injection pump. The medical injection pump comprises a controller, an executer, a pump core, a medicinal bag and a remaining needle, wherein the medicinal bag is communicated with an input passage of the pump core and used for storing liquid medicament, and the remaining needle is communicated with an output passage of the pump core; the controller receives injection instruction, transforms the instruction into injection command identified by the executer and sends the injection command to the executer; and the executer controls the liquid medicament injectedby the pump core through the remaining needle according to the injection command sent by the controller. The medical injection pump provided by the invention is convenient for a patient to use, and improves the accuracy of injection.

Description

technical field [0001] The invention relates to a micropump, in particular to a medical injection pump. Background technique [0002] Existing medical syringe pumps include syringe pumps such as insulin pumps and analgesic pumps. [0003] Insulin pumps are the best way to treat diabetes, but due to the high price of existing insulin pumps, most diabetic patients have not yet had the opportunity to receive this advanced treatment method for effective treatment. [0004] figure 1 It is an exploded diagram of the composition of the existing insulin pump. In the existing insulin pump, the motor 101 drives the screw rod 105 to rotate through the transmission device 102, and the screw nut 106 moves axially through the cooperation of the silk stem and the nut to push the piston 104 of the syringe 103 to output the medicinal liquid to the infusion set matched with the syringe. middle. A display 107 and a keyboard 108 are also provided on the traditional insulin pump housing 109 ...
