Vibration detection device for needles of insulin injection pens

Abstract

The invention discloses a vibration detection device for the needle of an insulin injection pen, which relates to the field of vibration detection, comprising: a support frame with a long chute inside; Above the support frame and through the support frame, and extending to the bottom of the support frame; a shaking mechanism with a shaking unit, the top of the shaking mechanism is slidably connected to the inside of the chute of the support frame, and extends downward for the injection pen The needle vibrates; the screw mechanism installed at one end of the support frame and penetrating to the inner wall of the support frame chute is used to drive the shaking mechanism to clamp the needle of the injection pen. The present invention provides a shaking mechanism with a shaking unit, which enables the insulin pen to swing back and forth while vibrating up and down, creating more complex vibration conditions, thereby improving the quality of inspection and further preventing defective products from leaving the factory.

Description

technical field [0001] The invention relates to the field of vibration detection, in particular to a vibration detection device for insulin injection pen needles. Background technique [0002] The insulin pen saves patients from the cumbersome process of extracting insulin from the insulin bottle with a syringe, saves patients from the embarrassment of injecting insulin in public places, and brings convenience to patients with poor eyesight or even blindness. Vibration testing is performed to detect if insulin will leak from the needle site to avoid problems with defective products. [0003] However, the current vibration detection device cannot perform vibration detection under complex behaviors. The detection process is generally a reciprocating vibration up and down, and it is impossible to make the insulin injection pen vibrate in other directions during the vibration detection process, which makes the vibration detection unable to imitate complex Vibration conditions, ...

[0003] However, the current vibration detection device cannot perform vibration detection under complex behaviors. The detection process is generally a reciprocating vibration up and down, and it is impossible to make the insulin injection pen vibrate in other directions during the vibration detection process, resulting in the vibration detection being unable to imitate complex behaviors. Vibration conditions, which cannot further improve its detection quality
