Description
Technical field
The present invention relates to animal physiological active material acquisition devices, and in particular to dog or cat class saliva collecting device.
Background technique
The method for acquiring saliva from animal oral cavity at present mainly spit follow the example of, swab stick method, intubation and modus operandi.
Spit that follow the example of be to clamp the fillers such as cotton balls, sponge with pliers and be put into animal mouthful that it is allowed to chew, by cotton balls, sponge etc.
Saliva on filler separates acquisition by way of being centrifuged or squeezing.This method is easy to operate, without anesthesia and other energy
Device, but collecting amount is few, saliva may be stained with hair or impurity, pollute saliva sample, and in collection process, do not have
The device of any fixed animal oral cavity, animal are not easy cooperation and collect.
Swab stick method is placed in swab stick in animal mouthful, and along insertion acquisition cotton head on the inside of cheek, acquisition cotton head is anti-with cheek
Multiple friction obtains saliva, and this method is swift to operate, and without starting acquisition position, but collecting amount is few, needs multi collect ability
Meet subsequent survey or test demand.
Intubation needs preparatory anesthetized animal, injects pilocarpinum, is then open and is intubated by salivary gland and received
Collection, it is more and pollution-free which collects saliva, but needs to anaesthetize every animal to be collected, needs professional technician, workload
Greatly, the saliva in addition collected is secreted under animal normal condition, and the saliva amount of collection is unable to estimate, and influences the standard of experiment
True property.
Modus operandi mainly with lower jaw gland, the parotid gland, sublingual gland or cheekbone gland conduit in operation separating animal's oral cavity, then passes through
Fistula is attached collection, and it is a kind of good collection method that the saliva that this method is collected is pollution-free, collecting amount is big, but hand
Art process is complicated, and has certain damage to animal, and fistula cannot retain for a long time in vivo, is not also suitable for a large amount of dynamic
Object acquires saliva.In addition, the major defect of above-mentioned acquisition device is that animal is not fixed firmly, if anesthesia is bad, it is easy to make
It is incomplete at saliva acquisition.
