AI Technical Summary

Technical Problem

Existing automatic syringes cannot provide the best injection depth according to different patients and injection sites, and there are problems such as waste of medicine, incorrect injection and complex operation when injecting on your own.

Method used

An intelligent automatic syringe with adjustable injection depth is designed, using a movable sheath and ratchet mechanism, combined with connecting rods and push rod teeth, to achieve dynamic adjustment of injection depth, and is equipped with identification devices, control devices and prompt devices to realize drug information identification, precise exhaust and automatic injection.

Benefits of technology

It realizes the independent selection of injection depth according to different patients and injection sites, accurately identifying drug information and intelligently adjusting injection parameters, reducing waste of drug fluid, improving the reliability and safety of injections, and supporting the intelligent interconnection of injection records.

Abstract

The present application provides an intelligent automatic injector with adjustable injection depth, including an injection depth adjustment mechanism, which includes: a push rod, which is configured to be able to push forward or retract backward, and the push rod is provided with push rod teeth; a ratchet, which is configured so that when the push rod is pushed forward, the ratchet is not rotated by the push rod teeth, and when the push rod is retracted backward, the ratchet is rotated by a predetermined angle by the push rod teeth; a connecting rod, which is provided with a connecting rod stopper, the connecting rod is configured to be able to move forward and retract backward along its longitudinal axis, and when retracting backward, the connecting rod stopper can abut against the ratchet and cannot continue to retract, and when the connecting rod contacts the ratchet at different positions, the length of the connecting rod extending from the housing is different; the connecting rod is configured to be able to contact the second end of the sheath, so that when the sheath is pressed on the injection site, it can retract with the retraction of the connecting rod, thereby exposing the needle of the prefilled injection syringe. According to the present application, the injection depth can be adjusted to achieve intelligent exhaust and injection.
