Ultrasonic measuring device for insulin injection pen needle

Abstract

The invention discloses an ultrasonic measuring device for an insulin injection pen needle, and relates to the field of insulin injection pen injection flow detection. The ultrasonic measuring device comprises a hollow needle-shaped test needle mechanism, a connector and an ultrasonic mechanism, wherein the connector is fixedly connected to the top end of the test needle mechanism and used for being in threaded connection with the output end of an insulin pen, and the ultrasonic mechanism is provided with an induction mechanism. According to the ultrasonic measuring device, the test needle mechanism is arranged to replace an injection needle, the inner diameter and length specifications of the test needle mechanism are the same as those of an existing injection pen needle on the market, the outer diameter of the test needle mechanism is amplified, and detection is facilitated while detection is not affected; and a driving mechanism and the induction mechanism are arranged, when different test needle mechanisms are replaced, the test needle mechanism can be quickly clamped, the connector can be quickly in threaded connection with the insulin injection pen, the induction mechanism can be opened and closed under the action of the driving mechanism, and therefore damage to a probe due to friction is avoided.

Description

technical field [0001] The invention relates to the field of detecting the injection flow rate of an insulin injection pen, in particular to an ultrasonic measuring device for the needle of an insulin injection pen. Background technique [0002] The insulin pen saves patients from the cumbersome process of using a syringe to extract insulin from the insulin medicine bottle, saves patients from the embarrassment of injecting insulin in public places, and brings convenience to patients with poor eyesight or even blindness. Insulin injection pens are generally equipped with There are syringe pumps, which inject insulin into the human body through injection pens and needles. The speed of insulin injection has a very important impact on product performance, and it cannot be too fast or too slow. [0003] However, the needles equipped with insulin injection pens are very thin, which is very inconvenient to detect, and the existing ultrasonic measuring device cannot be used to dete...

AI Technical Summary

Problems solved by technology

[0003] However, the needles equipped with insulin injection pens are very thin, which is very inconvenient to detect, and the existing ultrasonic measuring device cannot be used to detect them. The reason is that the clamp-type measuring device cannot be clamped on such a thin needle. At the same time, If a conventional needle on the market is used to test it, the needle must be discarded after the test, resulting in high testing costs
