Animal saliva collecting device

Abstract

The invention discloses an animal saliva collecting device, comprising an adsorption soft colloid, a saliva receiving cover, a saliva collecting device and an evacuating device, wherein one end of the adsorption soft colloid is fixed in the saliva receiving cover and the other end is a free end for an animal to chew; the saliva collecting device comprises a saliva collecting box, and a saliva inlet of the saliva collecting box is connected with the saliva receiving cover by a collecting pipe; the evacuating device comprises a vacuum suction pump which is connected with the saliva collecting box by a vacuum pipeline. By utilizing the animal saliva collecting device, a large amount of saliva can be collected without narcotizing animals and fixing animals by external force and without an operation.

Description

technical field [0001] The invention relates to animal experiment equipment, in particular to an animal saliva collection device. Background technique [0002] Animal saliva not only contains various proteins, but also DNA, RNA, fatty acids, and various microorganisms. Various protein components in blood also exist in saliva, and saliva can reflect changes in the levels of various proteins in blood. Many diseases of animals can be diagnosed by saliva detection, such as dog rabies, swine fever, swine foot-and-mouth disease immune antibody detection; in addition, salivary gland bioreactor is a new type of bioreactor, the protein secreted by salivary glands is rich in saliva Therefore, it is necessary to collect saliva for detection and purification. [0003] The secretion of saliva in animals is not limited by sex and developmental period. Animals secrete saliva throughout their life, and the amount of saliva secreted by large animals is large; in addition, salivary gland bio...

Problems solved by technology

[0004] At present, the methods of saliva collection mainly contain the following: 1. The direct cotton ball collection method mainly puts cotton balls, cotton cloth or sponges, etc. Squeeze or centrifugal separation, this method is simple and easy to operate, without anesthesia, but the collection amount is small, and special personnel are required to collect, and it is difficult for animals to cooperate with personnel to collect under passive conditions

2. Intubation method. This method first anesthetizes the animal, injects pilocarpine, and then collects it through the opening of the salivary gland. It can collect more saliva without pollution, but each animal needs to be anesthetized and intubated, requiring more staff , The workload is heavy, and the collected saliva is not secreted under the normal conditions of the animals

4. Fistula operation method, which mainly separates the ducts of the parotid gland, submandibular gland, and sublingual gland through surgery, and then connects and collects them through the fistula. The saliva collected by this method is pollution-free and has a large amount of collection. It is a good collection method, but The operation is troublesome, and it will cause some harm to the animals. The fistula can not be kept in the body for a long time, and it is not suitable for the collection of a large number of animals.
