Special extrusion-force-adjustable injector for veterinarians

Abstract

The invention discloses an extrusion-force-adjustable injector special for veterinarians. The extrusion-force-adjustable injector comprise an injection tube; a push rod is inserted into the top of theinjection tube; the bottom of the push rod is fixedly connected with a liquid push plate; the bottom of the liquid pushing plate is fixedly connected with an extrusion rod; an injection needle is inserted into the bottom of the injection tube; the left side of the injection needle is engaged with a clockwork spring wheel; a pull rod is rotatably connected to the bottom of the spring rod; an ejector rod is slidably connected to the surface of an inner wheel of a ratchet wheel; an inflation plate is fixedly connected to one side, away from the ratchet wheel, of the ejector rod; an inflation boxis slidably connected to the side face of the inflation plate; and an inflation pipe is fixedly connected to one side, away from the injection needle, of the inflation box. According to extrusion-force-adjustable injector special for veterinarians, through cooperative use of the extrusion rod and a clamping rod, the effects that the extrusion force borne by the needle head is automatically adjusted and the needle head is prevented from being continuously inserted into an animal when the animal reacts violently are achieved.

Description

technical field [0001] The invention relates to the technical field of veterinary medicine, in particular to a veterinary special syringe with adjustable extrusion force. Background technique [0002] A veterinarian is a doctor who prevents, diagnoses, and treats diseases for animals. Specifically, a veterinarian is a type of worker who uses medical methods to promote the coordination between the body of animals (including wild animals, poultry, livestock, and aquatic animals) with microorganisms and the natural environment. With such a booming pet market, veterinarians are very important. [0003] After the animal is sick, the veterinarian needs to use a syringe to inject the drug into the animal. However, during the injection process, the animal may react violently, causing the needle to go deep again after being inserted into the animal, and eventually the animal may be injured due to too deep insertion , so a syringe that can prevent the needle from being inserted too d...
