Automatic Needle Pricking Device for Electric Needle Syringe

Abstract

The invention discloses an automatic needle inserting device of an electric injector with a needle. The automatic needle inserting device comprises a needle head installing plate, compression springs, a switch device, a screw, nuts, guide rails, a limiting top plate expanding and retracting device, a spring box rack and a shell rack. A needle head is installed on the needle head installing plate, the needle head installing plate and the spring box rack can slide on the guide rails, a nut is installed on the spring box rack, the screw rotates to drive the spring box rack to move left and right to compress a spring, the compressed spring provides power for sliding of the needle head installing plate, the switch device controls whether the needle head installing plate to slide or not, and the limiting top plate expanding and retracting device adjusts the human body piercing depth of the needle head. When a great deal of livestock on a farm is injected, the automatic needle inserting device can be used for replacing the manual needle inserting process and achieve automatic needle inserting, the labor intensity of an injection worker is greatly reduced, injection efficiency is improved, and the injection difficulty is reduced.

Description

technical field [0001] The invention relates to a veterinary instrument, in particular to an automatic needle pricking device for an electric syringe with a needle. Background technique [0002] An electric needle syringe is a syringe that uses a motor to push a piston to inject medicine. This type of syringe is typically used to vaccinate livestock on large scale farms. Electric syringes with needles generally include power supply, motor, transmission device, injection device, controller, etc. The injection is completed by converting the power of the motor into the thrust of the syringe piston, which does not require manual pushing of the piston, which reduces the labor intensity of injection workers . Most of the existing electric injectors use a screw structure as its transmission device, which converts the rotational motion of the motor into the linear reciprocating motion of the syringe piston. [0003] At present, the injection device of electric syringes with needl...

AI Technical Summary

Problems solved by technology

[0003] At present, the injection device of electric syringes with needles is basically the same as that of manual syringes, so the needle insertion method is the same as that of manual syringes. It requires injection workers to have relatively rich injection experience, which increases the workload of injection workers and is easy to cause injection problems. Part damage
