Percutaneous sensor applying device

Abstract

The invention provides a percutaneous sensor applying device. The percutaneous sensor applying device comprises a base, a handle, a guide needle, a sensor unit, a support frame, a sensor bracket, a shuttling piece and a driving component, wherein the sensor unit comprises a sensor body and a sensor shell, and the sensor shell is provided with a through hole allowing the guide needle to pass through; the support frame is dismountably and fixedly mounted in the handle; the sensor bracket is coupled with the support frame and is used for supporting the sensor unit; the shuttling piece is used forsupporting and extending the guide needle passing through the through hole; the driving component is used for driving the shuttling piece to move towards a near end position; and when the handle moves to a second position from a first position, the support frame, the sensor bracket and the shuttling piece, as a whole, move to a most distal end position from a near end position, and when the support frame, the sensor bracket and the shuttling piece reach the most distal end position, the sensor bracket releases the sensor unit. Automatic penetrating and drawing out of the guide needle are realized, and besides, the percutaneous sensor applying device is simple to operate, comfortable to use, compact in structure, safe and reliable and favorable for popularization.

Description

Technical field [0001] The invention relates to a medical device for monitoring an analyte in a living body, in particular to a device for inserting an analyte sensor into the skin of a recipient. Background technique [0002] Diabetes is a disease caused by an abnormal condition of the pancreas in the patient's body, which cannot produce enough insulin. More severe patients may be accompanied by a series of complications in the later stage, such as kidney failure and skin ulcers. At the current medical level, no cure has been found for the disease, and blood sugar can only be controlled through diet or insulin. [0003] In most cases, diabetes uses traditional blood glucose meters and blood glucose test strips to monitor blood glucose values. The principle is to measure blood glucose by measuring the amount of current produced by the reaction of glucose in the blood and glucose oxidase in the test strip. Since the above blood glucose testing mostly uses fingertip blood, a diabet...

AI Technical Summary

Problems solved by technology

However, the structure of the applicator is relatively complicated, and the position accuracy of the sensor probe, guide needle and seal is very high, and the applicator is highly related to the structure of the sensor assembly, so it is difficult to cooperate with sensors from external manufacturers

The cost of the applicator is high, which is not conducive to the promotion and civilianization of products
