Technical field
This utility model relates to animal experiment device capable, more particularly, relates to a kind of experimental provision of analyzing rat footprint.
Background technology
Zoopery is important means and a method medically commonly used, can understand and verify some medical experiment results by zoopery.At present, the animal spinal cord damage test is undertaken by rat and corresponding experimental provision mostly, footprint analysis experiment is an important indicator of motor function recovery after the assessment Spinal Cord Injury in Rats of widely using in the world, traditional experimental provision is such: it is a narrow horizontal channel that can only allow rat walk forward, lay markd blank sheet of paper in the horizontal channel, to get rid of rat ground zero and the irregular footprint interference experiment result when the terminal point.When this experimental provision carries out footprint analysis experiment to rat, contaminate with nontoxic redness and black dyes respectively at the front and back of rat sole.The current experiments device is troublesome poeration not only, and the toe seal that rat stays on blank sheet of paper is also unintelligible.Owing to sole before and after the rat is smeared reasons such as pigment is deep mixed, also can cause footprint to measure problems such as inaccurate.
Summary of the invention
At the deficiencies in the prior art, the purpose of this utility model provides a kind of device of analyzing the laboratory animal footprint, and it not only can make rat move on the runway of regulation, and can gather rat footprint data easily.
The purpose of this utility model is achieved in that a kind of device of analyzing the laboratory animal footprint, comprises cabinet, and the straight-line runway of suitable rat is arranged in the cabinet, and the footprint signal plate is arranged at the bottom of runway; The footprint signal plate is a dianegative, and perhaps the footprint signal plate is provided with signal of telecommunication sensing element and signal output mechanism.
On the basis of technique scheme, this utility model also has following further scheme:
Described footprint signal plate and cabinet constitute separable structure.
Described signal of telecommunication sensing element is a touch screen.
Described footprint signal plate surface is arranged with 10 electrodes at least.
The corresponding camera head of described dianegative.
Described dianegative is by the corresponding camera head of illuminator.
Advantage of the present utility model is as follows:
Because, being provided with the suitable straight-line runway of rat in the cabinet, the footprint signal plate is arranged at the bottom of runway; The footprint signal plate is a dianegative, and perhaps the footprint signal plate is provided with signal of telecommunication sensing element and signal output mechanism.So, when the footprint signal plate is dianegative, can use video camera to see through the footprint that dianegative photographs rat easily; When the footprint signal plate is provided with signal of telecommunication sensing element and signal output mechanism, can convert the footprint of rat to the signal of telecommunication, can import Computer Processing to the signal of telecommunication by the signal output mechanism.This utility model can use the shooting mode to obtain the rat footprint image easily, perhaps obtains and can be saved great amount of manpower and material resources when carrying out the spinal cord injury zoopery by the signal of telecommunication of Computer Processing.
