Abstract
The utility model relates to a rat fixer relates to the experimental animals fixed network. One kind and be used for fixed rat to carry out the device that experiment operation such as blood and injection were got to the tail vein, including fixed cover of head and the fixed cover of afterbody. The fixed cover of its head has the cross section of reducing design and communicate with each other end to end, and its both sides are still with the fixed orifices, and is main according to the long and narrow bodily form of rat and design the fixed rat head of being convenient for, the cross section that the fixed cover of afterbody has the reducing design equally just communicates with each other end to end, and its somatic part both sides have fixed rope, and the rat afterbody passes through and then the operation with vertically the open -ended is convenient for through the groove, the part junction has elasticity end to end, and afterbody spare top links to each other with head spare afterbody. Can get operations such as blood, back end whip experiment, tenderness measurement by the simple and convenient rat afterbody vein that carries on of ten minutes through the device to time spent is short, and is with low costs.
Description
Technical field
This utility model relates to laboratory animal technique for fixing field, belongs to rat kind experimental tool, the experiment being mainly used for fixing rat and then operating on it.
Background technology
Because rat is used for various experimentation, but at present how the device that its afterbody gets the experiments such as blood is fixedly carried out for it and still lack simple and practical feature.Rat fixing device conventional at present, a part only has and is fixed the trunk of rat, lack necessary head to fix, or the space of components of fixing head is comparatively large, because rat head is long and narrow, tail is long close with height, disposition is slightly violent, if therefore not good to its stationary device, there is potential danger for experimentation personnel in this, and also increases the degree-of-difficulty factor of experiment.Be not specifically designed in current existing rat fixing device rat tails get the instrument of the operation such as blood or device too complicated, the used time expends time in longer, and cost is higher.
Summary of the invention
This utility model provides a kind of rat fixing device, to solve Problems existing in background technology.
The technical solution of the utility model is as follows: a kind of rat fixing device, carries out the experimental implementation such as tail venous blood sampling and injection, tail-flick test, tenderness measurement, comprise head fixed cover and afterbody fixed cover for fixing rat; Described head fixed cover adopts the head fixed cover body communicated end to end of variable diameter design to form with the fixing hole being positioned at described head fixed cover body both sides by cross section; Described afterbody fixed cover is adopted the afterbody fixed cover body communicated end to end of variable diameter design by cross section, is positioned at the described static line of afterbody fixed cover body both sides and the rat tails of longitudinal opening consists of groove.
The beneficial effect that this utility model obtains is: (1) structure is simple, to rat noinvasive, and especially convenient batch production; (2) cross section of head fixed cover of the present utility model and afterbody fixed cover all adopts variable diameter design, can be good at the health of the rat adapting to the different bodily form, can be good at rat being fixed within this utility model device, connection simultaneously between head fixed cover of the present utility model and afterbody fixed cover can regulate within the specific limits, the health of the rat of different length can be adapted to, thus there will not be rat head in experimentation, twist the operation hindering experimenter; (3) this utility model adopts the rat tails of longitudinal opening by groove, after rat is fixing, facilitates picking rat tails to carry out the experimental implementation such as tail venous blood sampling and injection, tail-flick test, tenderness measurement.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, this utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.

1 head fixed cover; 2 afterbody fixed covers; 3 head fixed cover bodies; 4 fixing holes; 5 static lines; 6 afterbody fixed cover bodies; 7 rat tailses pass through groove.
Detailed description of the invention
First, refer to shown in Fig. 1, a kind of rat fixing device, comprise head fixed cover 1, the afterbody fixed cover 2 be connected with head fixed cover 1 bottom; The cross section of described head fixed cover 1 expands gradually from top to bottom, and the cross section of described afterbody fixed cover 2 reduces gradually from top to bottom; Described head fixed cover 1 and afterbody fixed cover 2 are cavity structure, and the top of head fixed cover 1 and afterbody fixed cover 2 and bottom are all in hatch frame; The diameter of described afterbody fixed cover 2 is less than head fixed cover 1 slightly, and has certain elasticity, and the top of afterbody fixed cover 2 can enter the bottom of head fixed cover 1; There is static line 5 both sides of described afterbody fixed cover 2, and there is fixing hole 4 both sides of described head fixed cover 1, by described static line 5 through fixing hole 4, head fixed cover 1 and afterbody fixed cover 2 are linked together; Described afterbody fixed cover 2 there is a rat tails longitudinally opened the door by groove 7, after rat is fixing, conveniently pass through, outside groove 7 picking rat tails to device, to carry out related experiment by described rat tails.
Use procedure: experimenter utilizes rat to like the habit of holing, with left hand, head fixed cover 1 is placed on before rat, pierce after head fixed cover 1 until rat, the right hand is rapidly by afterbody fixed cover 2 insertion head fixed cover 1, according to the long distance regulating afterbody fixed cover 2 to enter of rat body, then static line 5 is fixed through fixing hole 4, carries out the experimental implementation such as tail venous blood sampling and injection, tail-flick test, tenderness measurement by rat tails by groove 7 picking rat tails.
Claims (1)
1. a rat fixing device, is characterized in that: comprise head fixed cover (1) and afterbody fixed cover (2); Described head fixed cover (1) is made up of head fixed cover body (3) and the fixing hole (4) that is positioned at head fixed cover body both sides; Described afterbody fixed cover (2) consists of groove (7) the rat tails of afterbody fixed cover body (6), the static line (5) being positioned at afterbody fixed cover body both sides and longitudinal opening.
