Description

Technical Field

[0001] The invention belongs to the field of veterinary medical instruments, and in particular relates to an automatic ejection intramuscular injection device. Background Art

[0002] Intramuscular injection of drugs to wild animals has always been a very troublesome thing. Wild animals are highly vigilant and aggressive, so they cannot be directly injected intramuscularly. Generally, they need to be immobilized before intramuscular injection. In order to make it more convenient to inject drugs to wild animals intramuscularly, flying needle injection is generally used. Currently, flying needle injection is mainly to use a veterinary anesthesia blowpipe or anesthesia gun to launch a syringe, and then the syringe injects the drug solution into the animal's body.

[0003] The tranquilizer gun generally uses the high-pressure gas generated by gunpowder or the high-compressed gas stored in the gas tank as the power to push the syringe through the barrel to the target, and then the syringe injects the drug into the target. The tranquilizer gun belongs to the category of firearms, which is difficult to apply for equipment. The management and economic costs of storage and use are high. It is mainly a passive ambush and cannot actively pursue the target. The operator needs professional training. The tranquilizer gun has a great impact force and causes great damage to the animal, which is difficult to be widely used.

[0004] Veterinary anesthesia blowpipes use metal or plastic tubes as launch devices to put syringes into the tubes. People blow air into the tubes to push the syringes to accelerate in the tubes and then release them from the launch devices and launch them into the target. The syringes then inject the drugs into the target. Veterinary anesthesia blowpipes are widely used, but they have defects such as short use distance, difficulty in approaching target animals, inability to treat highly alert targets and long-distance targets, and difficulty in ensuring operator safety when facing more dangerous targets. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an automatic ejection intramuscular injection device which has a simple structure, is easy to use and store, has a low cost, is safe to operate, has a wide range of applications, and can deliver medication to a target at a long distance.

There is no need for the operator to approach the wild animal at close range, which ensures the safety of the operator and improves the hit rate. The ejection force is moderate, and it will not cause harm to the animal due to excessive ejection force like guns and other equipment.

[0034] In this embodiment, the ejection device 3 includes a cap 31, a spring 32, and a connector 33 for connecting the cap 31 and the spring 32.

When the limiting column 41 is placed horizontally in the cavity of the launch tube 1, the syringe 2 and the ejection device 3 are limited, so that they cannot be ejected. When it is necessary to launch, the limiting column 41 is pulled out of the through hole to release the limit, and at this time, the syringe 2 is ejected out under the action of the ejection device 3 to realize the launching process.

[0039] In this embodiment, the remote control component 6 includes a transmitting end and a receiving end. The transmitting end includes a transmitting antenna, a transmitting radio frequency module and a transmitting control circuit board for controlling the transmitting signal.
