Intelligentized insulin pen

Abstract

The invention provides an intelligentized insulin pen, comprising a housing, a blood glucose testing module, a control module, an insulin storehouse, an insulin refrigeration module, and an insulin injection module. The blood glucose testing module comprises a MEMS blood glucose testing electrode which can be repeatedly used. The MEMS blood glucose testing electrode is provided with a microgroove, and a reference electrode, a working electrode, and a counter electrode are made in the microgroove. The blood glucose testing module comprises an electrode cleaning fluid and an electrode cleaning conduit, used to clean the blood glucose testing electrode. The insulin dose injected by the insulin injection module can be obtained by calculating a blood glucose value which is measured by the blood glucose testing module, and can be manually adjusted on the basis. The insulin pen solves a problem in the prior art that a blood glucose testing test strip cannot be reused, and a problem that blood glucose concentration of a diabetic cannot control dose of the injected insulin, and the insulin pen also solves problems in the prior art that an insulin pen needs refrigeration and is not convenient to carry with a user.

Description

technical field [0001] The invention belongs to household medical equipment, in particular to an intelligent insulin pen. Background technique [0002] Diabetic patients need to inject insulin for blood sugar control. Generally, before insulin injection, a blood sugar test is required to adjust the dosage of insulin according to the level of blood sugar concentration. Existing blood glucose meters use disposable blood glucose test strips, which are discarded after a blood glucose test and cannot be used any longer. The price of domestic blood glucose test strips is generally 1-2 yuan each, such as Sinocare, Aike, Yuyue, Yicheng, etc. The price of imported blood glucose test strips is generally 2-5 yuan each, such as Johnson & Johnson, Abbott, Omron , Bayer, Roche, etc. Severe diabetic patients need to measure blood sugar 3-4 times a day, and disposable blood glucose test strips will bring a certain economic burden to diabetic patients. If a reusable blood glucose detectio...

Problems solved by technology

[0005] The present invention proposes an intelligent insulin pen, which solves the problem in the prior art that the blood glucose detection test strips cannot be reused, and the problem that the blood glucose concentration of diabetic patients cannot control the dosage of injected insulin, and solves the problem in the prior art. Insulin pens need to be refrigerated, which is inconvenient to carry around

[0006] The inventive idea of ​​the present invention is: aiming at the problem that the blood glucose detection test strips in the prior art cannot be reused, the present invention designs a blood glucose detection electrode based on the MEMS (Micro-Electro-Mechanical System, Micro-Electro-Mechanical System) processing technology, A microgroove is etched on the surface of the base material by deep etching technology, and then a working electrode, a reference electrode and a counter electrode are photoetched in the microgroove by a photolithography process, and a sufficient amount of catalytic material (such as glucose oxidase or nanocatalytic Material) is fixed on the surface of the working electrode, and a protective layer is added to the outer layer of the catalytic material, such as polyurethane, polyurethane, Nafion, polyvinylidene fluoride, polycarbonate, cellulose acetate, polyvinyl chloride, polytetrafluoroethylene, etc.
