Benefits of technology

This technology helps detect if there are any problems with an injection device's needles without having them be blocked by things around it or being hidden from viewing during operation. It also makes sure that this problem can be detected accurately while still providing reliable signals for accurate control over how much medicine needs to inject into patients.

Problems solved by technology

The technical problem addressed by this patented technology relating to an improved method for detecting if there are any issues with current methods that involve sensitivity to rotation caused by the movement during injection procedures.

Abstract

The invention discloses a needle-cylinder-state detection device for a high pressure injector. The needle-cylinder-state detection device comprises a rotating part and a fixing part. The rotating part comprises a rotating body, a buckling block, a plurality of grooves formed in the other end of the rotating body, a first limiting block arranged on the outer side of the rotating body, a second limiting block arranged on the outer side of the rotating body and an opto-coupling light shielding clamping jaw arranged between the first limiting block and the second limiting block; the fixing part comprises a fixing body, a first limiting column, a second limiting column, a first detection optocoupler adjacent to the first limiting column, a second detection optocoupler adjacent to the second limiting column and elastic column plug pieces arranged on the fixing body and fixedly matched with the grooves. According to the needle-cylinder-state detection device for the high pressure injector, needle-cylinder state detection is free of blind area, using is convenient, and the reliability of needle-cylinder detection signals is guaranteed.
