Description

Needle fixer for remote intramuscular injection of animals

Technical Field

The utility model relates to a veterinary appliance, in particular to a needle fixer for remote intramuscular injection of animals.

Background

In the livestock raising process, large-scale intramuscular injection water is often needed for curing or preventing various diseases caused by livestock infection, and medium-and large-scale livestock such as pigs, cattle, sheep, horses, donkeys and the like are surprised when being subjected to intramuscular injection.

In recent years, some devices for remotely injecting livestock have appeared on the market, namely, a long rod is used for grasping a needle, a person stands at a place with a certain distance from the livestock to quickly insert the needle into the livestock, the needle is provided with a hose connected with a hanging bottle or a syringe, the livestock can walk for a while after the needle is inserted, and the livestock can not walk after pain is relieved, so that the intramuscular injection of the medicine can be successfully completed.

These long-stick devices on the market also suffer from certain drawbacks, particularly the inability of the long-stick to effectively disengage from the needle after the needle has been pricked, sometimes even pulling the pricked needle out, resulting in a failed intramuscular injection.

Disclosure of Invention

Therefore, the utility model provides the universal needle fixer for the remote intramuscular injection of the livestock, which can lead the long rod to be effectively separated from the needle in time when the needle is inserted in a distance range of non-surprise or less-surprise livestock, and avoid the situation that the inserted needle is pulled out again, thereby improving the success rate of the remote intramuscular injection and overcoming the defects in the prior art.

The utility model provides a veterinary remote intramuscular injection universal needle fixer which is provided with a hand-held rod, a main sleeve and a clamp, and is characterized in that a core plate is arranged in the main sleeve, a clamp shaft and a clamp arm of the clamp are fixed on the core plate, the other clamp is exposed out of the main sleeve for being pressed to enable a jaw to clamp a needle, a reset spring is arranged between the two clamp arms to keep the force of stretching the two clamp walls, and the lower ends of the exposed clamp arms are bent and are provided with hooked teeth; a sliding sleeve is arranged beside the clamp fixing arm on the core plate, a contact-release rod is arranged in the sliding sleeve, the upper end of the contact-release rod extends out of the main sleeve so as to be in contact with livestock during intramuscular injection, a rack perpendicular to the contact-release rod is arranged at the middle section, the lower end of the contact-release rod is propped against the clamping spring, and the clamping spring keeps the pushing force of the rack so that the rack hooks the hooking teeth of the clamp; the lower end of the main sleeve is connected with the hand-held rod.

The part of the main sleeve mounting core plate is divided into a mounting opening in half, the mounting opening is provided with an arch plate with the same diameter as a cover plate, and the cover plate is connected or hinged with the main sleeve through screws.

The lower end of the main sleeve is provided with connecting threads which are movably connected with the hand-held rod.

The clamp jaw is provided with an anti-slip pad to prevent the head of the hand from slipping and skewing during clamping.

The anti-slip pad is a rubber sheet or a sponge pad.

Openings are arranged at the upper ends of the main sleeve and the cover plate so as to facilitate the installation of the needle head and the passage of the transfusion hose.

The upper end of the contact-release rod extends 3-9mm higher than the clamp when the needle is clamped, so that the needle can be enabled to be propped against the livestock to trigger the clamp to release after being effectively pricked, and the needle is separated from the clamp.

The lower end of the clamping spring is propped against the spring seat, the upper end of the clamping spring is propped against the rack, the spring seat is two protruding tables protruding from the core plate, and the lower end of the contact-release rod moves up and down between the two protruding tables. .

The hand-held rod, the main sleeve, the cover plate and the core plate are all made of materials such as plastics and metals, and the clamp shaft and the clamp fixing arm are fixed on the core plate by self-tapping screws.

The working principle of the utility model is as follows:

When in use, the hand pad rod is connected with the main sleeve, the prepared liquid medicine is filled into the infusion bottle or the syringe, the infusion hose is used for communicating with the injection needle, one hand holds the main sleeve and presses the touch-off rod to open the jaw, the needle is placed into the jaw, the inner pressure forceps expose the arm, and the forceps clamp the needle to implement remote intramuscular injection.

When the injection is performed, an operator slowly stretches the needle towards the needle at a place which is not surprised by livestock, the needle is forced to prick after approaching, the needle can immediately prop against the touch-release rod after being pricked into the livestock, the force of the clamping spring is overcome after the touch-release rod is pressed, the rack and the hook teeth are loosened, the clamp is opened immediately, the needle is separated from the clamp, the livestock can start to slightly harassment, the needle is quickly calm along with the alleviation of pain until the injection of the liquid medicine is completed, and the long-distance intramuscular injection is completed after the needle is drawn out.

The operation is repeated in this way, and the intramuscular injection of the whole livestock can be smoothly realized by only 1-2 people.

Therefore, the utility model can lead the long rod to be separated from the needle head in time and effectively when the needle is inserted in the distance range of the livestock which is not or less frightened, thereby avoiding the situation that the inserted needle head is pulled out again and obviously improving the success rate and the working efficiency of the remote intramuscular injection.
