Description

Technical Field

[0001] The utility model relates to the technical field of animal husbandry and veterinary diagnosis and treatment, in particular to an animal oral cavity opener. Background Art

[0002] Animal husbandry refers to the production sector that raises livestock and poultry to obtain animal products or draft animals by grazing, confinement or a combination of the two. It includes livestock breeding, poultry breeding, economic animal domestication, etc. When animals are raised, they may occasionally suffer mouth injuries due to infection from ingesting debris and need treatment. At the same time, when treating sick animals, the animal's mouth needs to be opened to feed medicine, or the infected part of the mouth needs to be treated.

[0003] When performing oral treatment and feeding medicine to an animal, a mouth opener is needed to open the animal's mouth.

[0004] Oral expanders usually rely on grooves or convex plates to contact the animal's teeth and gums to limit the expander and prevent it from falling out of the mouth during use. Since the arrangement and size of the teeth and gums of animals of different sizes and species are different, only the corners of the two ends of the grooves or convex plates are in contact with the species' teeth and gums. Due to the small contact area, it is easy to cause damage to the animal's teeth and gums. Utility Model Content

[0005] The utility model provides an animal oral cavity opener to solve the problem in the prior art that, due to the different arrangement and size of the teeth and gums of animals of different sizes and species, only the two end corners of the groove or convex plate are in contact with the teeth and gums of the species, and the small contact area can easily cause damage to the teeth and gums of the animals.
