Abstract
The utility model discloses a rat constraining device. The rat constraining device comprising a constraining frame and a constraining cylinder; the constraining frame comprises a base and supports which are fixed on bilateral sides of the base; a horizontal rod is connected between the supports; the constraining cylinder is fixed on the horizontal rod; the constraining cylinder comprises an inner sleeve and an outer sleeve which are mutually nested; a cylinder cover covers at one end of the inner sleeve; the other end of the inner sleeve is inserted into the outer sleeve with a sealed end. The rat constraining device solves the problems that testing results are not accurate and the efficiency is low due to the fact that testing devices are not standard when models such as rat depression and chronic stress are produced.
Description
Technical field
This utility model belongs to a kind of biotic experiment equipment, is specifically related to a kind of rat restraint device.
Background technology
During the models such as making rat depression and chronic stress, usually to carry out the chronic unpredictability minimal irritation of serial CUMS() stimulate or CUS stimulation (chronic unpredictable sexual stimulus).A kind of stimulation mode commonly used in stimulating course is fettered rat.According to the experiment needs, rat need to be placed on to a relatively airtight environment, limit its activity.In scientific experiment, method commonly used is that rat is filled in a homemade container or in carafe at present.Operate so lack of standardization and easily cause experimental error: the narrow degree varies of on the one hand homemade container size is difficult to reach the requirement of experiment, causes experimental result inaccurate; On the other hand, because number of containers is limited, complete after a rat at every turn and carry out again next only operation, expend time in.
The utility model content
When solving models such as making the depressed and chronic stress of rat, experimental facilities is lack of standardization cause cause the problems such as result of the test is inaccurate, efficiency is low, this utility model has designed a kind of rat restraint device.
The technical scheme that this utility model addresses the above problem is: a kind of rat restraint device, comprise constraint frame and constraint cylinder, the support that the constraint frame comprises base and is fixed on the base both sides, connect cross bar between support, the constraint cylinder is fixed on cross bar, the constraint cylinder comprises two mutually nested inner and outer sleeves, and inner sleeve one end cap has cover, in the outer sleeve that other end intercalation is at one end sealed.Its advantage is: this device mainly comprises constraint frame and two parts of constraint cylinder, can fix at most a plurality of constraint cylinders on the constraint frame.Open the lid of constraint cylinder during use, the rat of crawl is placed in the constraint cylinder, according to the size of rat, after regulating the position of constraint cylinder inner and outer sleeves, cover the lid of constraint cylinder.
Described rat restraint device, rack surface has the sliding tray vertical with base, and is connected with cross bar by bolt.Its advantage is: can regulate by bolt the height of cross bar.
Described rat restraint device, arrange a plurality of constraint cylinders on cross bar, cross bar is spirally connected fixing with the constraint cylinder.Its advantage is: can fetter many rats at every turn simultaneously, heighten conventional efficient.Each constraint cylinder is fixed on fixed mount by the screw of bottom, and the constraint cylinder can conveniently unload and load onto.
Described rat restraint device, inner and outer sleeves adopts respectively the lucite one to form.Its advantage is: lucite has fabulous light transmission, the convenient observation, and mechanical strength is higher, and certain heat-resisting tolerance to cold is arranged, and corrosion-resistant, insulating properties are good.
Described rat restraint device, outer sleeve surface has screw, and controls the relative position of inner and outer sleeves by screw.Its advantage is: can regulate the position of inner and outer sleeves, then by screw, be fixed and get final product.
Described rat restraint device, the base below is rubber mat fixedly.Its advantage is: while keeping test, and the stability of base and support.
This device is simple to operate, while being used for carrying out rat constraint stimulation test, can accomplish simple and convenient and standard.
The accompanying drawing explanation
Fig. 1 is this utility model structural front view;
Fig. 2 is this utility model structure side view;
Fig. 3 is this utility model constraint barrel structure schematic diagram;
In figure, 1, the constraint frame; 1-1, base; 1-2, support; 2, constraint cylinder; 2-1, inner sleeve; 2-2, outer sleeve; 3, cross bar; 4, cover; 5, sliding tray; 6, bolt; 7, screw; 8, callosity.
The specific embodiment
Below in conjunction with accompanying drawing, structure of the present utility model is explained in detail to explanation, as Fig. 1 is this utility model structural front view; A kind of rat restraint device, comprise constraint frame 1 and constraint cylinder 2, the support 1-2 that the constraint frame comprises base 1-1 and is fixed on the base both sides, connect cross bar 3 between support, the constraint cylinder is fixed on cross bar, the constraint cylinder comprises two mutually nested inner sleeve 2-1 and outer sleeve 2-2, and inner sleeve one end cap has cover 4, as Fig. 3 is this utility model constraint barrel structure schematic diagram; In the outer sleeve that other end intercalation is at one end sealed.Rack surface has the sliding tray vertical with base 5, as Fig. 2 is this utility model structure side view; And be connected with cross bar by bolt 6.Arrange a plurality of constraint cylinders on cross bar, cross bar is spirally connected fixing with the constraint cylinder.Inner and outer sleeves adopts respectively the lucite one to form.Outer sleeve surface has screw, and controls the relative position of inner and outer sleeves by screw 7.The base below is rubber mat 8 fixedly.
The constraint frame is made by steel matter, and the constraint cylinder is made by transparent lucite; Can fix 4 constraint cylinders on each constraint frame; Below base, there are four rubber mats to be screwed on base.Support welding is on base.Each constraint cylinder is fixed on cross bar by the screw of bottom, and will fetter cylinder can unload, and the rat of crawl is placed in to constraint cylinder inner sleeve, after regulating the position of constraint cylinder inner sleeve and outer sleeve, covers the lid of constraint cylinder; Regulate the cross bar height, then will fetter on wound packages and fetter frame.
Technique scheme has only embodied the optimal technical scheme of technical solutions of the utility model; those skilled in the art have all embodied the principle of utility model to some changes that wherein some part may be made, within belonging to protection domain of the present utility model.
