Description

Technical Field

[0001] The present invention relates to the technical field of livestock breeding, and particularly relates to a veterinary medicine feeding device. Background Art

[0002] At present, the livestock industry is developing towards large-scale and standardized development. Through large-scale domestication and cultivation of economically valuable animals such as beasts and birds, and by utilizing their growth and reproduction functions, livestock products are obtained. When developing the livestock industry on a large scale, special attention should be paid to applying modern scientific concepts to carry out breeding measures such as epidemic prevention for animals such as beasts and birds to ensure the health and safety of livestock products. To prevent diseased poultry from circulating in the market and to ensure the safety of meat food for the people, local product quality inspection centers, quarantine stations and other department agencies will also strictly inspect the health of livestock and poultry in the farms within their jurisdiction.

[0003] During the process of livestock and animal breeding, livestock and poultry will get sick due to their own weakened resistance or environmental factors, and need to be diagnosed by a veterinarian. Once it is diagnosed that livestock and poultry have diseases, they often need to be treated with medicine. If the treatment is not timely, it will cause the death of livestock at best, and in severe cases, it will lead to the outbreak of infectious diseases, which will bring huge economic losses to the breeding industry. When a veterinarian feeds medicine to livestock and poultry, due to the strong self-protection awareness of animals and poor cooperation, the veterinarian has to force-feed the medicine, or can also use a medicine feeder to feed the medicine. Currently, the medicine feeder usually has a structure similar to a syringe, and the liquid medicine is injected into the mouth of livestock and poultry by pushing a piston. In order to facilitate the feeding of the liquid medicine, a pressing plate or a mouth-opening structure is usually provided at the injection port to open the mouth of livestock and poultry. The common mouth-opening structure includes two mounting plates connected by a spring or an elastic member. Although the above pressing plate and mouth-opening structure can play a certain role in opening the mouth of livestock and poultry, the elastic force of the spring is limited, so it cannot be used for livestock and poultry of quite different body sizes. At the same time, when opening the mouth of livestock and poultry through the spring, the animal may overcome the elastic force and forcibly close its mouth due to its self-protection awareness, resulting in damage to the teeth, gums or inner wall of the oral cavity of livestock and poultry.

When feeding medicine, that is, the slider 22 slides towards the end close to the support rod 31, so that the second push rod 54 drives the second piston 53 to move synchronously towards the end close to the support rod 31. When the second piston 53 moves, the air in the first chamber is pushed out and guided into the airbag 5 through the air tube 51, thereby playing a role in inflating the airbag 5. The airbag 5 can be inflated while the support rod 31 is being spread. In this embodiment, the movement of the slider 22 can, on the one hand, adjust the angle of the two support rods 31, and on the other hand, inflate the airbag 5.

[0030] Among them, the other structures of this embodiment are the same as those of Embodiment 1, which is only an optimization of Embodiment 1.
