AI Technical Summary

Technical Problem

Existing portable blood glucose meters are cumbersome to operate, requiring users to drip blood onto the test strip themselves, and the lancet is prone to accidental injury.

Method used

Design a rapid blood collection structure for a blood glucose meter that utilizes capillary action and magnetic adsorption to automatically drop blood onto the test strip. A tilting positioning slider and a push rod mechanism ensure stable pushing of the blood collection needle and automatic detection.

Benefits of technology

The blood glucose testing process has been simplified, with blood dripping onto the test strip automatically, avoiding accidental injury and improving ease of operation and safety.

Abstract

The utility model relates to a blood sampling structure belongs to blood glucose appearance technical field, concretely is a kind of rapid blood sampling structure of blood glucose appearance, including shell, the outside of shell is provided with test paper, the inside of shell is provided with blood sampling subassembly, the inside of shell is provided with ejection assembly;The utility model, push the inside of fixed block to jack, the position of jack is stuck by positioning sliding block, when needing blood sampling, positioning sliding block is lifted up and is staggered with the side wall of puncture needle, the elastic push of ejection spring moves jack and puncture needle outward, so that puncture needle punctures the skin of patient, when blood overflows from puncture, since the tip of puncture needle is immersed in blood, blood enters the inside of capillary through communicating hole by capillary principle, finally, drop on the side wall of test paper by the end of puncture needle, reach the effect that the blood glucose of patient is detected automatically;Solve the problem that the blood glucose detection operation process of existing is complicated.
