Hole, the circumferential direction of 3 lower inner wall of mouse room is equipped with an annular air-pocket 5, has the rat-tail hole stretched out for rat-tail below annular air-pocket 5
6。
It further include the air charging system that can be inflated for annular air-pocket 5, air charging system is connected to annular air-pocket 5 by tracheae.
Air charging system is inflatable ball 4 in the present embodiment, it is further preferred that can be with the inflatable ball 4 of one-handed performance.It can certainly
Aforementioned inflatable ball 4 is substituted using the higher type of respiration air feeder of existing the degree of automation.Type of respiration air feeder is for example existing
Ventilator.
In the present embodiment, it is provided in separatory funnel 8 for urinating the sieve 9 for passing through and retaining mouse excrement for mouse, into one
Step is preferably: sieve 9 is the circular steel silk screen being arranged at 8 neck of separatory funnel.Certainly it can also be adopted for different needs
With other existing funnel devices with similar liquid separation function.
The fast collecting method of rat fresh excreta and urine involved in the present embodiment, can realize by aforementioned device
It can also be implemented separately comprising following steps:
I, it is nested with the rat standing posture lifted of holding fore paw and at the waist and belly of its body an annular air-pocket 5.Its
In, by the rat standing posture lifted of holding fore paw and an annular air-pocket 5 is nested at the waist and belly of its body can lead to
It crosses to stand rat and be realized in the mouse room 3 of such as aforementioned device.
Ii, annular air-pocket 5 is repeated inflation/deflation operation, by the contraction that swells repeatedly of annular air-pocket 5 to rat abdomen
Realize simulation massage to promote rat to void excreta and urine in portion.Wherein, inflation/deflation operation is repeated to annular air-pocket 5 can be with
It is realized by the inflatable ball 4 of such as aforementioned device.
Iii, pass through separatory funnel 8 and the collection rat excrement of collection vessel 10 and/or urine below rat.Wherein, divide
Liquid funnel 8 and collection vessel 10 are placed sequentially in the lower section of mouse room 3 as in aforementioned device.Separatory funnel 8 can be using such as
The structure recorded in aforementioned device.
Of the invention is not limited to the above embodiment, and the technical solution of above-mentioned each embodiment of the invention can be handed over each other
Fork combination form new technical solution, in addition it is all using equivalent replacement formed technical solution, all fall within the present invention claims guarantor
It protects in range.
