Description

The big rat holder of behavioristics's experiment

Technical field

This utility model belongs to experiment and uses the equipment technical field, is specifically related to a kind of big rat holder that is used for the experiment of all kinds of behavioristicss.

Background technology

Experiment behavioristics is the behavior by means of the experimentation animal.In experiment behavioristics, usually use a model.In the making of model and later every experimental implementation process, thereby the capital is caused to stimulate to laboratory animal inevitably and is caused the various stress of animal, this will badly influence the accuracy of experiment, will hinder the experimental implementation that the experimenter carries out when serious.In addition, the experiment of many behavioristicss often requires to carry out under quiet environment.Therefore,, stimulate, guarantee the accuracy of experiment and reduce as far as possible again on the other hand carrying out behavioristics when experiment fixing laboratory animal on the one hand.

Summary of the invention

The purpose of this utility model is to provide a kind of environmental stimulus that reduces, and guarantees to test the big rat holder of behavioristics's experiment of accuracy.

Big rat holder is used in the behavioristics's experiment that the utility model proposes, and it comprises bracing frame, cylindrical shell, and bracing frame is made up of base plate and top board, and both locate by the side plate support fixation in the side.On the bracing frame side plate hole is arranged, have crotch on the top board, cylindrical shell is hung on the crotch, base plate is arranged with fixedly pillar, is used to bind the control of the fixedly tightness of band; Cylindrical shell is arranged in bracing frame, cylinder top has ventilation and administration port, this port stretches in the hole on the side plate of bracing frame, be used for animal breath, anesthesia and oral administration etc., the side of cylindrical shell has for animal foot and passes the through hole of cylindrical shell and the through hole that binding is brought into out, and the rear portion of cylindrical shell is with respect to animal (rat) tail position, is provided with the steady seat of lengthening formula and is used for the animal tail and fixes, steady seat top, cylindrical shell rear portion is provided with rotary door, can prevent the animal escape after shutting.

This utility model also can be lumped together by above-mentioned some (as 3-10) single fixture combination, can carry out a plurality of rat experiments simultaneously.

This utility model holder has solved arresting in the rat experiment process, injection and per os, extremity administration and other experimental implementation preferably, make that animal periphery environment of living in experimentation is comparatively suitable, thereby reduce the interference of environmental stimuli as far as possible, guaranteed the accuracy of experimental implementation experiment.

Number in the figure: 1 is bracing frame, and 2 is cylindrical shell (retainer body), and 3 is fixed leg, and 4 are breathing, administration port, and 5 is the animal limb through hole, 6 are binding band through hole, and 7 are the steady seat of lengthening, and 8 is door, and 9 is crotch, 10 are the binding band, and 11 is top board, and 12 is side plate, and 13 is base plate.

The specific embodiment

Support frame structure is seen shown in Figure 2.Bracing frame side plate 12 has hole, and top board 11 has crotch 9, can make things convenient for the loading and unloading of holder cylindrical shell, is arranged with fixed leg 3 above the base plate 13, is used to bind the control of the fixedly tightness of band.Its specification is as follows: length=100mm, and height=70mm, wide=270mm, top fixed hook spacing 120mm, nearside panel link up with apart from limit 80mm, and the distally hook is apart from close opposite side 70mm.The bottom fixed leg is divided into 3 rows, and every row has fixed leg 8-10 approximately, fixed leg spacing 10mm, and array pitch 30mm, nearside panel fixed leg is apart from side panel 120mm.

Retainer body (cylindrical shell) structure is seen shown in Figure 3.Whole cylindrical, cylinder top has ventilation and administration port 4, be used for animal breath, anesthesia and oral administration etc., the bottom surface of cylindrical shell has the through hole 5 that passes cylindrical shell for animal foot, the side has the through hole 6 that outlet is brought in binding into, and the rear portion of cylindrical shell is equipped with the steady seat 7 of lengthening formula with respect to animal (rat) tail position, is used for the animal tail and fixes, there is rotary door 8 steady seat top, cylindrical shell rear portion, can prevent the animal escape after shutting.Its specification is as follows: cylindrical shell length overall=250mm, the administration port of wherein ventilating is long 10mm, the cylindrical shape of diameter 30mm (operation instruction sees accompanying drawing 6 explanations for details), the steady seat of rear portion lengthening 7 long 50mm, it on it rotary door 8, cylindrical shell side, bottom surface are that through hole is respectively applied for the binding band and animal foot passes, and the cylindrical shell middle part has the groove mouth of wide about 20mm, can be used for fixing or other experimental implementation.

The holder bottom surface is seen shown in Figure 4, and the bottom surface has through hole 5, and is pre-small post-large, and the front and back limb of corresponding laboratory animal penetrates respectively.Front side through hole spacing 40-45mm, rear side through hole spacing 50-55mm; Front and back side through hole is ellipse, and front side through hole length axial length is respectively 15mm, 10mm, and rear side through hole length axial length is respectively 25mm, 20mm.

Retainer body (rear side) is seen shown in Figure 5.Binding is with 10 front ends that hook is arranged, and passes cylindrical shell by side through hole 6 and can link with the fixed leg 3 of different distance and adjust the tightness of binding animal from interior, and binding is with 10 length also can in the light of actual conditions set up on their own.

Rat places cylindrical shell during use, closes to the doorstep in case it is escaped, and the cylindrical shape port 4 of barrel front end can see through bracing frame lateral aperture and extraneous UNICOM, convenient breathing, administration of anaesthesia etc.This administration port can be detachable screw thread mouth, and the metal string bag is contained in the centre, can place the ether cotton balls of anesthesia usefulness etc. every wire netting, and anesthetized animal also can carry out the administration of women's head-ornaments portion or other experimental implementation etc. by this mouth simultaneously safely and fast.

Fig. 7 provides the combined fixator diagram.Bracing frame can be as shown in Figure 2,4 or more mostly be a monoblock and produce in batches.
