Abstract
The utility model discloses a rat bounding cylinder. The rat bounding cylinder comprises a cylinder body which is in a straight cylinder shape and a cylinder head which is in a conical cylinder shape; the cylinder body is provided with a plurality of injection through holes; the bottom of the cylinder body is provided with a rat inlet; the front end of the cylinder head is provided with a rat breathing hole; the cylinder body is fixedly connected with the cylinder head through two semicircular clamps; connecting portions of the cylinder body and the cylinder head are provided with abutting joint protruding edges; grooves which are used for locking the abutting joint protruding edges of the cylinder body and the cylinder head are formed in the semicircular clamps respectively; one ends of the two semicircular clamps are hinged together through a pin shaft; the other ends of the two semicircular clamps are fixed through a locking bolt and a locking nut. According to the rat bounding cylinder, a rat can be fixed in the cylinder for injection or blood operation, the rat can be rapidly and conveniently taken out after the operation is achieved, and harm to the rat is not produced in the taking-out process.
Description
Technical field
This utility model relates to a kind of medical experiment equipment, especially a kind of rat restraint device of injecting for rat is fixed up or drawing blood operation.
Background technology
In the time rat being injected or draw blood operation, because rat build is larger, tooth is sharp, careless slightly will being bitten by rat.CN201275157Y discloses and has a kind ofly held Mus device for anaesthesia experiment white mouse, this device comprises transparent plastic Mus cylinder, the cover for clamping Mus body, described cover is tightly placed in the outer wall of Mus cylinder opening, the stack shell of described Mus cylinder is provided with several through holes inserting for anaesthetic needle, and this Mus device of holding that is used for anaesthesia experiment white mouse has advantages of simple in structure, easy to use, safe.But, while adopting this device to fetter rat, rat can be tried one's best and be climbed to Mus cylinder front end, therefore, can be very difficult in the time rat being taken out after injection or blood drawing EO, sometimes even rat tail is broken and rat can not be pulled out in cylinder, easily rat is damaged, affect the carrying out of subsequent experimental.
Utility model content
The technical problem that utility model will solve is: a kind of rat constraint cylinder is provided, this rat constraint cylinder can be fixed on rat enforcement injection or blood drawing operation in cylinder, after EO, can quickly and easily rat be taken out, taking-up process can not damage rat.
The technical scheme that technical solution problem is taked: a kind of rat constraint cylinder, comprise straight tube shape cylindrical shell and cone barrel cylinder head, on cylindrical shell, be provided with multiple injection open-works, be provided with rat import at cylinder body bottom, be provided with rats breathing hole at a cylinder front end, cylindrical shell and cylinder head are connected and fixed by two semicircle anchor ears, connecting portion at cylindrical shell and cylinder head is provided with respectively docking chimb, in semicircle anchor ear, be provided with the groove of cylindrical shell and the locking of cylinder head docking chimb, two semicircle anchor ear one end are hinged by bearing pin, and the other end is fixed by clamping screw, nut.
Beneficial effect: rat constraint cylinder of the present utility model, owing to having adopted described rat constraint cylinder to comprise straight tube shape cylindrical shell and cone barrel cylinder head, on cylindrical shell, be provided with multiple injection open-works, be provided with rat import at cylinder body bottom, be provided with rats breathing hole at a cylinder front end, cylindrical shell and cylinder head are connected and fixed by two semicircle anchor ears, connecting portion at cylindrical shell and cylinder head is provided with respectively docking chimb, in semicircle anchor ear, be provided with the groove of cylindrical shell and the locking of cylinder head docking chimb, two semicircle anchor ear one end are hinged by bearing pin, the other end passes through clamping screw, the technical scheme that nut is fixing, before to rat execution injection or blood drawing operation, utilize two semicircle anchor ear docking to be fixed into integrative-structure straight tube shape cylindrical shell and cone barrel cylinder head, experimental rat is introduced in cylinder from the rat import of cylinder body bottom, rat creeps active to cylinder head place, and head is tightly inserted into a pneumostome place for head, now, by the injection open-work on cylindrical shell, rat is implemented to injection or blood drawing operation, when injection or blood drawing finish after, the clamping screw of outwarding winding, nut, two semicircle anchor ears are opened, now, straight tube shape cylindrical shell and cone barrel cylinder head are separated, rat can be discharged fast, and by rat take out process in without firmly pullling, avoid in taking-up process, rat being come to harm, make rat can continue follow-up experiment.
Brief description of the drawings
Below in conjunction with detailed description of the invention, rat constraint cylinder of the present utility model is described in further detail.
Fig. 1 is the structural representation of rat constraint cylinder of the present utility model.
Detailed description of the invention
As shown in Figure 1, rat constraint cylinder of the present utility model, comprise straight tube shape cylindrical shell 8 and cone barrel cylinder 2, on cylindrical shell, be provided with multiple injection open-works 9, be provided with rat import 10 at cylinder body bottom, be provided with rats breathing hole 1 at a cylinder front end, cylindrical shell and cylinder head are connected and fixed by two semicircle anchor ears 6, connecting portion at cylindrical shell and cylinder head is provided with respectively docking chimb 5, in semicircle anchor ear, be provided with the groove 4 of cylindrical shell and the locking of cylinder head docking chimb, two semicircle anchor ear one end are hinged by bearing pin 3, and the other end is fixing by clamping screw, nut 7.
