Abstract

The utility model discloses a mouse fixing device, which is formed by a rectangular transparent plastic box and a steel-wire-mesh flat board bottom. The mouse fixing device is characterized in that hind limb fixing holes for fixing hind limbs are arranged at the position which is 2.5-3.5 millimeters away form the tail end of the rectangular transparent plastic box, and a U-shaped pressing plate is disposed on the upper end of the rectangular transparent plastic box. The pressing plate is provided with hind limb fixing holes, and the height of the pressing plate can be adjusted according to requirements to limit movements of a mouse and fix hind limbs of the mouse. A tail plate is formed by steel-wire-mesh blocking slices and can be opened and closed, and a bottom plate is formed by steel wire meshes and connected with the rectangular transparent plastic box through a screw and can be opened and closed. The mouse can be directly placed into the mouse fixing device to be fixed. The mouse fixing device is suitable for beginners to use, and simultaneously facilitates a plurality of experimental operations of lab assistants to the mouse, such as intraperitoneal injections, caudal intravenous injections and the like. The whole mouse fixing device has simple structure and low production cost, is convenient to use and easy to carry, and avoids being bit by the mouse.

Description

A kind of little rat holder

Technical field

This utility model relates to the device of a kind of fixedly mice, specifically relate to a kind of in laboratory the fixing little rat holder of white mice.

Background technology

Mice is a kind of medical research laboratory animal commonly used, be multidisciplinary laboratory animals commonly used such as medical science, biology, pharmacology, pathology, need protect it during extracting bites, administration can be directly arrested in of short duration operations such as intraperitoneal administration, but when intraperitoneal administration or tail vein injection or tail venesection etc. are operated repeatedly as need, need the long period to fix, need to use corresponding little rat holder.Holder commonly used had plastic cylinder dress holder, scalable length holder was arranged in the test in the past, but exist mouse web portion fully not expose, be unfavorable for problems such as experimental implementation, simultaneously slick holder is unfavorable for that mice puts into, especially for the student that can not arrest mice, arrest mice and put it into itself and also have very big difficulty.In addition, general simple and easy little rat holder can not limit the activity of mice in holder by regulating, and fixedly there is the control method complexity in assorted mice, and price is more expensive, has hindered its application in teaching and experiment.For solving mice the problems referred to above, designed the little rat holder of this utility model.

Summary of the invention

Problem to be solved in the utility model provide a kind of simple in structure, easy to use, be beneficial to experimental implementation, prevent the little rat holder that mice is bitten.

For addressing the above problem, the technical scheme that this utility model adopted is:

Little rat holder, constitute by the dull and stereotyped end of rectangle transparent plastic box, steel wire, it is characterized in that: described rectangle transparent plastic box front end is shorter, and the rear end is higher, apart from tail end 2.5-3.5 centimeters the one fixing fixed hindlimb hole of mouse hind leg is arranged, there is a U type pressing plate upper end, the fixed hindlimb hole is arranged on the pressing plate, can adjust screw as required, to regulate U type pressing plate height, and then limit the activity of mice, and mouse hind leg is fixed.Tailgate is made by steel wire, can open and close, and the centre has one than macropore, mousetail can be taken out, and uses for tail vein injection.Base plate is made by steel wire, is tabular, is connected by screw with the rectangle transparent plastic box, can open and close.

This utility model can be put into mice fixing by opening tailgate; In the time of also can creeping to steel wire flat board base plate, the rectangle Transparent Plastic Box Lid of top be closed, need not contact mice and can realize putting into mice, be fit to very much the abecedarian and use by mice.Base plate and tailgate steel mesh structure porous make things convenient for the laboratory technician mice to be implemented kinds of experiments operations such as lumbar injection, tail vein injection simultaneously.This utility model has changed the thinking of in the past only being placed mice by tail end, adopts rear end and bottom all can open the thinking of placement flexibly.In addition, the fixing restriction that reaches the mice range of activity for mouse hind leg, adopted the U type pressing plate that can adjust height to implement, can realize fixed hindlimb and the active restriction of mice well, this regulative mode is the more simple easy operating of operation of the little rat holder of scalable more in the past.Whole fixer structure is simple, and production cost is low, and is easy to use, be easy to carry about with one, and prevents biting of mice.

The specific embodiment

When needing fixedly mice, can open mice holder tailgate, mice is put into, the steel wire tailgate is covered.Simultaneously adjust the top pressing plate, the activity of restriction mice, and fixing mouse hind leg according to mice size and experiment demand.As the needs tail vein injection, mousetail is taken out from tail end steel wire baffle plate space, during as the need lumbar injection, mouse hind leg can be taken out earlier fixingly from the space, steel wire circle hole of fixed hindlimb, see through steel wire then mice is carried out lumbar injection.

For arresting the unskilled primary operator of mice, can directly bottom baffle be opened, mice crawls into the top, bottom, directly the plastics semicircular cylinder is covered, and regulates the pressing plate of top, and the restriction mice is movable to get final product.

Claims

1. little rat holder, constitute by the dull and stereotyped end of rectangle transparent plastic box, steel wire, it is characterized in that: described rectangle transparent plastic box has the fixing fixed hindlimb hole of hind leg apart from tail end 2.5-3.5 centimeters, there is a U type pressing plate upper end, the fixed hindlimb hole is arranged on the pressing plate, can adjust height as required, tailgate and base plate are made of steel wire, all be connected by screw, can open and close with the rectangle transparent plastic box.
