Description

Animal farm animal is injected with anesthesia flying needle
Technical Field
The invention relates to an anesthesia flying needle for injecting animals in the field of livestock raising.
Background
In the daily nursing of animals, how to inject the medicine into the animals is always a matter which troubles veterinarians, especially for wild animals with large body size, violent characters and strong commonness, before the veterinarian approaches the animals, the animals need to be anesthetized and calmed by using an anesthetic flying to perform subsequent work.
The existing anesthesia flying needle is disclosed as 'an animal anesthesia flying needle' in Chinese patent CN106137452B, the anesthesia flying needle comprises an injection device and a launching device, the injection device comprises a needle head and a needle tube, a first piston and a first connecting rod are arranged in the needle tube, the tail end of the first connecting rod is positioned outside the needle tube, an elastic resetting device used for applying an acting force towards the needle head to the first connecting rod is arranged between the tail end of the first connecting rod and the needle tube, the needle head comprises a needle stem and a needle point, the needle point is of a sealing structure, a side hole is arranged on one side of the needle stem, and a sliding block capable of sliding back and forth along the needle stem is arranged around the side hole. The launching device comprises a launching cylinder, a pressure cylinder, a second piston and a second connecting rod, wherein the inner diameter of the launching cylinder is smaller than that of the pressure cylinder, the launching cylinder is communicated with the pressure cylinder, and the second piston is located in the pressure cylinder.
When the needle is used, firstly, the medicine is extracted, the sliding block is manually moved away, the sliding block enables the side hole in the needle stem to be opened, the side hole is soaked in the medicine liquid, the tail end of the first connecting rod is stretched backwards, the medicine liquid is sucked in the needle tube, then the sliding block is manually moved, the sliding block is enabled to plug the side hole, and at the moment, the elastic resetting device is in an energy storage state; and secondly, launching the flying needle, placing the needle tube in a launching barrel of the launching device, launching the flying needle by pressing a second piston, pushing the sliding block to move backwards by the skin of the animal when the flying needle is inserted into the animal, so as to leave the side hole, releasing energy by the elastic resetting device, and injecting the medicine in the needle tube into the animal by the first piston.
However, in use, the existing anesthetic flying needle has the following problems: in the first step of medicine extraction, the slide block needs to be moved manually to open the side hole, and after the medicine extraction is finished, the slide block needs to be moved manually to close the side hole, so that the process is troublesome, and the slide block dipped with the medicine is not easy to operate by hands; in the process of launching the minute needle by the launching device in the second step, the diameter of the tail end of the first connecting rod is consistent with that of the needle tube, so that the tail end of the first connecting rod directly bears the gas pressure of the pressure tube, however, the force transmission path after the tail end of the first connecting rod is stressed is that the tail end of the first connecting rod transmits the stress to the first piston through the first connecting rod, the first piston is transmitted to the needle tube through the medicament in the needle tube, finally, the needle tube is stressed and flies out, the whole force transmission path is long, and the compressible part is arranged in the force transmission path, so that the launching of the whole launching device has certain time delay after the second piston is pressed, aiming at animal injection, the finding of a proper injection opportunity is not easy, the launching time delay of the launching device can possibly cause the animal to be out of place, the failure of the minute needle injection is caused, in addition, in the process of loading the needle tube into the launching device, it is not easy to determine when the needle cannula is assembled in place.
