Veterinary injector

Abstract

The invention provides a veterinary injector and belongs to the technical field of medical devices. The veterinary injector comprises an injection cylinder, an infusion hose, a needle seat, a needle, a limiting ring, a pivot-rotating device, a piston and a piston rod. The limiting ring is arranged on the output end face of the needle seat; the input end face of the needle seat is connected with the output end face of the injection cylinder through a plurality of first springs; and the pivot-rotating device comprises levers and pushing rods, the front ends of the levers are provided with a stop piece, and the rear ends of the levers are connected with one ends of the pushing rods in a pivoted mode. According to the veterinary injector, the needle with the hose is conveniently pricked into an animal body through the springs; the length of the needle into the animal body is limited through the limiting ring; meanwhile, the phenomenon that the needle shakes, thus the needle is deviated or falls off can be prevented through the limiting ring; through the pivot-rotating device, the needle pricking and injection action is sequentially completed at a time, and the situation that in the needle pricking process, a medicine is pushed out is avoided; and through the pivot-rotating device, the labor is relatively saved in medicine pushing, and operation is quite convenient.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a veterinary syringe. Background technique [0002] A veterinary syringe is a device designed specifically for injecting drugs into animals. When the existing veterinary medicine injects the animal with a syringe, the animal will struggle when the needle first enters the animal body. At this time, when the veterinarian continues to insert the needle into the animal body, the needle will be displaced due to the animal's struggle. Or the consequences of needle removal, more serious may lead to the needle breaking in the animal body. Generally, when injecting, the syringe plunger is pushed to inject the drug after the needle reaches the specified penetration depth. However, the current syringes often inject the drug when the syringe penetrates the skin and muscle of the animal. , did not reach the injection depth specified in the drug use operation, wasting the...

When the existing veterinary medicine injects the animal with a syringe, the animal will struggle when the needle first enters the animal body. At this time, when the veterinarian continues to insert the needle into the animal body, the needle will be displaced due to the animal's struggle. Or the consequences of needle removal, more serious may cause the needle to break in the animal body

Generally, when injecting, the syringe plunger is pushed to inject the drug after the needle reaches the specified penetration depth. However, the current syringes often inject the drug when the syringe penetrates the skin and muscle of the animal. , did not reach the injection depth specified by the drug use operation, wasting the drug and reducing the effect of treatment or prevention
