Description

technical field [0001] The invention relates to a veterinary oral spacer, belonging to the technical field of animal husbandry and veterinary related equipment. Background technique [0002] With the development of large-scale and intensive animal husbandry, higher and higher requirements have been put forward for breeding management and veterinary medical level. In the process of animal husbandry, due to the needs of drug injection, oral examination, gastric lavage, etc., the oral cavity of the livestock needs to be opened, and this operation will be difficult to complete without the aid of tools. To this end, people have invented oral spacers for opening the mouths of livestock. [0003] The existing oral spreader has the following problems when using it: first, when using it, the mouth of the animal needs to be slightly opened, and then the mouth spreader is inserted into the mouth of the animal, and then the mouth spreader is operated. The mouth of the livestock is ope...

Problems solved by technology

[0003] The existing oral spreader has the following problems in use: first, when in use, the animal’s mouth needs to be slightly opened to a gap, then the oral spreader is inserted into the animal’s mouth, and then the oral spreader is operated to handle Open the mouth of livestock, but in general, it is difficult for livestock to cooperate, and even injuries may occur. Therefore, the existing oral retractors have the problem of being difficult to insert into the oral cavity of livestock; secondly, in the process of using the oral retractor In this case, the animal may react violently, which can easily lead to the detachment of the oral retractor from the animal's mouth
