Abstract

The invention provides an insulin pump capable of automatically detecting the amount of medicine charged and a method for automatically detecting the amount of medicine charged. The insulin pump includes a casing, a control module, a DC servo motor, a drug delivery transmission assembly driven by the DC servo motor, and a cartridge for containing medicine. The drug delivery transmission assembly includes a screw rod and a push rod, which are used to convert the output torque of the DC servo motor into the axial torque of the push rod. In particular, a position switch is provided in the housing for detecting whether the cartridge entering the housing along with the push rod reaches a set position. The present invention realizes the automatic detection of the initial drug dosage of the drug cartridge, avoids the error caused by the visual inspection of the initial drug dosage in the prior art, improves the accuracy of data processing, and ensures that the insulin pump can control the regularity of normal pancreas secretion. Simulation effect.

Description

technical field

[0001] The invention relates to a method for automatic operation of a medical auxiliary automatic injection device, in particular to a method for automatically detecting the initial drug charge and a medical auxiliary automatic injection device for implementing the method. Background technique

[0002] Insulin pump is an important medical instrument for the treatment of diabetes that imitates the work of the normal pancreas of the human body and is manufactured on the principle of human bionics. Insulin pump, also known as open-loop artificial islets, adopts continuous subcutaneous insulin infusion method to continuously infuse the basal amount of insulin required by the human body in accordance with the normal pancreatic secretion law, and at the same time, timely inject large doses of insulin required before meals into the body. In vivo infusion to supply the needs of normal human body, so as to make blood sugar control stable, so that patients can return t...

Embodiment Construction

[0037] Further details will be given below in conjunction with the preferred embodiments shown in the accompanying drawings.

[0038] The present invention proposes a method for automatically detecting the amount of medicine based on an insulin pump, a preferred embodiment of the present invention, such as Figure 1 to Figure 4As shown, the insulin pump includes a casing 50 , a control module 40 , a DC servo motor 10 , a drug delivery drive assembly 20 driven by the DC servo motor 10 and a cartridge 30 for containing medicine. The cartridge 30 includes a cartridge 31 and a pusher piston 32 for pushing out the medicine. The drug delivery transmission assembly 20 includes a screw rod 22 and a push rod 21 for detachably connecting the medicine pushing piston 32 for converting the output torque of the DC servo motor 10 into the axial direction of the push rod 21. moment. The method comprises the steps of:

[0039] A. A position switch 60 is provided in the housing 50 for detect...
