When the present invention is in use, there are two methods of use, namely, adhering the positioning unit to the body of an animal requiring multiple injections, or using one positioning unit to sequentially use it on multiple animals. And the present invention is used for breeding animals that can realize the fast and stable bonding of the positioning unit, such as pigs, cattle, horses, etc., or to scrape off the long hair in some areas of other animals, so as to facilitate and realize the washing glue 14 and the like with the body surface. bonding.

The first method of use is to bond a positioning unit to each animal that needs multiple injection treatments. At this time, some adhesive tapes can also be used to strengthen the bonding and positioning ability. The marking stamp 15 can leave a mark on the body surface, even if it is dropped It can still be identified that the needle unit and the injection unit can be plugged and used for each injection.

The connection between the drug injection unit and the needle tube unit is realized by the plug connection between the docking port 21 and the plug port 7 and the plug pipe 12 and the butt pipe 20, and the plug pipe 12 and the butt pipe 20 are plugged and fixed to ensure a stable connection to the end. Turn on the electric push rod 10 and work for a short time, push the piston to push out the medicine part, so that the medicine enters the injection needle 11, and the air is discharged, and then press down and rotate the injection needle 11, the injection needle 11 penetrates the animal body subcutaneously along a circular trajectory, The length of piercing can be determined according to actual needs. After piercing a certain length, such as more than half of the length, the injection needle 11 is not easy to be separated. You can release your hand, turn on the electric push rod 10 again, and work slowly to inject the medicine in the syringe 3. In the animal body, after the injection is completed, the electric push rod 10 is controlled to work in the reverse direction, the output end is recovered, and the piston is driven to move. The setting of the valve 9 can meet the conversion requirements of injecting the medicinal liquid and extracting the medicinal liquid. Reverse rotation takes out the injection needle 11 from the animal body, exits along the circular trajectory, and pulls out the needle tube unit. The needle tube unit can be collected and sterilized for reuse. The procedure is the same when injecting the next animal.

The second method of use utilizes the feature that the washing glue 14 can be used multiple times, and uses a positioning unit to sequentially inject multiple animals, that is, the drug discharge tube 6 and the main shaft 19 are fixedly connected, and a new needle tube unit needs to be connected each time. , after connecting the positioning unit, the adhesive positioning is realized on the animal, and then the drug is injected. After the injection is completed, the injection needle 11 is withdrawn, the positioning unit is removed, and the injection is performed again with a new needle tube unit, and the remaining steps are similar to the first method. In the second method of the present invention, the drug injection unit and the positioning unit can be kept in a connected state all the time, and only a new needle tube unit needs to be plugged and connected each time, which is convenient to use and suitable for one-time injection.

In the first method of use of the present invention, when only one-time injection is performed, multiple positioning units can be arranged in batches and installed one-to-one at the same time, and then the first method is used for injection.

In the second method of use, the water-washing glue 14 can be cleaned by the brush 25, which is convenient for multiple use and easy to operate, and can simultaneously use the ink pad in the isolation tube 26 to feed the marking seal 15.

When the present invention is in use, the automatic withdrawal of the injection needle 11 can be realized by adding a torsion spring 27. The torsion spring 27 accumulates force when pressing down, and it is necessary to continuously apply pressure manually during the injection process. down, the injection needle 11 is automatically withdrawn. At the same time, a clamping device can be added together. During injection, the clamping device can achieve angular positioning of the main shaft 19. After the injection is completed, the clamping device is removed and rotated under the action of the torsion spring 27. The torsion spring 27 and the front plate 16 can be plugged and fixedly connected. When needed, plugged and fixedly connected. When not used, disconnected and the needle can be withdrawn manually, which can be selected and used according to different situations.

In the first method of use, since the positioning unit has been fixed on the animal body, the positioning plate 13 can be split into two parts, the left plate 28 and the right plate 29, that is, the left and right ends of the positioning plate 13 are connected in rotation. Through the rotation of the left plate 28, the injection position can be adjusted to avoid puncturing the same position all the time.

Both the positioning unit and the needle tube unit can be reused many times. In order to ensure that the injection needle 11 coincides with the circular trajectory when it rotates, each can be tested for the trajectory to ensure that the positioning unit and the needle tube unit can be used directly. Can be matched in sets.

The injection needle 11 is not limited to a quarter-circle length, and can be adjusted as required to ensure that the injection needle 11 is on a circular trajectory and can move along the circular trajectory. At the same time, the overall thickness of the positioning unit and the circular radius of the injection needle 11 also determine the shape of the injection needle 11 piercing the animal, the depth it can reach, etc., and they can be made in different models to improve practicability.

The present invention can be used in combination with an animal immobilization device, and in consideration of safety, the animal immobilization device is used to immobilize the animal to reduce animal activity. After the injection needle 11 of the present invention is pierced, the connection is stable, and it is not easy to run the needle, and the connection of the drug discharge tube 6 can provide a large amount of activity. Injections are also available.
