Abstract

With the insulin pump provided by the present invention, a user (patient) can obtain sufficient drug effects by introducing an appropriate amount of drug solution into a living body. The insulin pump (100) has an injection unit (disposable injection unit 110), an infusion unit (120) (disposable infusion unit 120A and reusable infusion unit 120B), a detection unit (140) and a control unit (150). Here, the control unit restricts the action of filling the infusion unit (infusion tube 121) or the injection unit (cannula 111) with insulin (S) by the infusion set (infusion set 122) and / or injecting insulin (S) into the infusion unit (infusion set 122) based on the detection result of the detection unit. The action of administering insulin in a living body.

Description

technical field [0001] The present invention relates to a drug solution administration device used for administering a drug solution into a living body. Background technique [0002] As a device for administering a drug solution such as insulin, there is known a portable drug solution administration device that administers a drug solution over time while being attached to the skin of a user (patient) to be administered. In the drug solution administration device, as an administration operation, it is possible to continuously and automatically administer a preset amount of drug solution to the patient, or to increase the amount of drug solution based on instructions from the patient during meals or exercise. With such a medical solution administration device, the patient can be properly administered with an appropriate amount of the medical solution, and can perform activities with a sufficient effect of the drug. [0003] However, if the administration operation is performe...
