Vibration detection device for insulin injection pen needle

Abstract

The invention discloses a vibration detection device for an insulin injection pen needle, and relates to the field of vibration detection. The device comprises a supporting frame which is internally provided with a strip-shaped sliding groove; a driving mechanism which is provided with a connecting ball and a lower pressing plate, wherein the driving mechanism is installed above the supporting frame, penetrates through the supporting frame and extends to the position below the supporting frame; a shaking mechanism provided with a shaking unit, wherein the top end of the shaking mechanism is connected into the sliding groove of the supporting frame in a sliding mode, extends downwards and is used for shaking the injection pen needle; and a lead screw mechanism which is mounted at one end of the supporting frame, penetrates through the inner wall of the supporting frame sliding groove and is used for driving the shaking mechanism to clamp the injection pen needle. By arranging the shaking mechanism with the shaking unit, the insulin pen can swing back and forth while vibrating up and down, and more complex vibration conditions are created, so that the detection quality is improved, and defective products are further prevented 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, ...
