The preferred technical scheme of the embodiment is as follows: the tail of the blowing needle is fixedly connected with a tail feather (not shown in the figure) for keeping the air flight stable.

Working process

In the embodiment, the experimental pig is taken as an example, and the anesthesia blow pipe is formed by connecting two front and rear blow pipes with the same inner diameter in a threaded manner and is provided with a laser positioner. The injection needle tube of the anesthesia blow needle is formed by refitting 5ml and 10ml injectors. Wherein the small pig (25-45kg) is treated with 5ml blow needle, and the vegetable pig (65-150kg) is treated with 10ml blow needle. Blow tubes also come in two sizes. Wherein a blow pipe matched with the 5ml blow needle is a PVC pipe with the outer diameter of 32mm and the wall thickness of 7 mm; a blow pipe matched with a 10ml blow needle is a PVC pipe with the outer diameter of 40mm and the wall thickness of 7.5 mm. When the tail feather injector is used for a long distance, tail feathers can be added at the tail of the injector to ensure the balance of the aerial flight.

Referring to fig. 6a-6b in detail, after the blow needle is assembled, anesthetic is extracted, and the side hole of the needle head is blocked by a rubber sleeve to expose the needle tip; the elastic rubber ring penetrates through the needle head through a round hole on the side wall of the elastic rubber ring and is sleeved on the handle part of the core rod of the injection needle tube along the axial direction of the injection needle tube; the anesthesia blow needle is arranged in the blow pipe through the threaded connection part of the anesthesia blow pipe; opening the laser positioner, aiming, and blowing out forcibly; the rubber sleeve which originally blocks the side hole of the needle head is blocked by the skin of an animal and slides backwards; while the needle tip pierces the skin and continues to advance toward the muscle layer. The medicine in the blow needle pushes the handle part of the core bar of the injection needle tube and the medicine liquid by the elasticity of the elastic rubber ring to complete the injection. The length of the rubber sleeve can be adjusted to meet different injection depths. Such as subcutaneous injection, intramuscular injection.

Note that:

1 before use, the laser positioner is calibrated.

2 the anesthetic blow needle is not aimed at the person.

3 when used for a long distance, the blowing needle can be added with tail feather, so as to ensure the stable flying in the air.
