Description

Mouse living body fixing device suitable for laboratory

Technical Field

The utility model relates to a mouse live body fixing device suitable for laboratory.

Background

At present, in a laboratory, the rats are generally directly held and fixed by hands when the rats are subjected to gastric lavage and injection administration. The most common administration mode in the laboratory is oral gavage administration, and the method is usually applied to multi-disciplinary animal modeling such as physiology, pharmacology and the like. For beginners, the experiment termination is often caused by injuring the airway or esophagus of the rat, inserting blood vessels, or even injuring the internal organs of the mouse due to over-force holding the rat, hand trembling and the like.

The existing fixing device for the rats is mainly concentrated on the fixation of the rats in the tail vein test, can only be used for the fixation of the tail vein test, and related fixing equipment for rat administration does not appear.

The technical scheme of the utility model lies in: a mouse living body fixing device suitable for a laboratory comprises an outer barrel, wherein an inner barrel is arranged in the outer barrel, the inner barrel is connected with the outer barrel through a plurality of fixing rods, a fixing mechanism is arranged in the inner barrel, and an elastic net mechanism is arranged at the bottom of the outer barrel.

Further, fixed establishment is provided with at least one central spring including setting up two splint in the inner tube between two splint, be provided with the pressing handle on the splint.

Further, the pressing handle comprises at least one push rod fixed on the clamping plate, the push rod penetrates through the inner cylinder and the outer cylinder in sequence, and the tail end of the push rod is provided with a handheld handle.

Furthermore, a cover plate is arranged right above the spring, two ends of the cover plate are fixed to the top of the inner cylinder, and the cover plate is made of plastic steel.

Furthermore, the one side that inner tube and splint are relative is provided with the latex pad, the splint also is provided with the latex pad with the relative one side of inner tube.

Further, the elastic net mechanism comprises a fine metal net, a plurality of shaking springs are arranged on the periphery of the fine metal net, and the other ends of the shaking springs are fixed on the inner wall of the outer cylinder.

Further, the mouse pad also comprises a cover cloth covering the surface of the mouse.

Compared with the prior art, the utility model has the advantages of it is following: the novel structure is simple, easy to use and can be operated by one hand; the fixing mechanism is arranged to fix the four claws of the mouse, so that the mouse is prevented from moving around in the experiment process; the elastic net mechanism is arranged, so that the four claws of the rats are prevented from being injured due to tension and sloshing; the latex pad is arranged, so that the four claws of the mouse are prevented from being injured due to extrusion; because the fixed posture of the rats is similar to the normal crawling posture, the psychological burden on the rats is avoided.

Detailed Description

In order to make the aforementioned features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below, but the present invention is not limited thereto.

Refer to fig. 1-2.

A mouse living body fixing device suitable for a laboratory comprises an outer barrel, wherein an inner barrel is arranged in the outer barrel, the inner barrel is connected with the outer barrel through a plurality of fixing rods, a fixing mechanism is arranged in the inner barrel, and an elastic net mechanism is arranged at the bottom of the outer barrel. The fixing mechanism is arranged to fix the mouse on the upper portion of the inner barrel, the four claws of the fixing mechanism stretch into the fixing mechanism, the elastic net mechanism is arranged to prevent the claw of the mouse from being injured, and meanwhile, the elastic net which can be gripped is arranged on the claw of the mouse.

In this embodiment, fixed establishment is including setting up two splint in the inner tube, and the fixed of mouse claw is realized to being close to each other through splint and inner tube, is provided with at least one center spring between two splint to realize that the splint is close to the inner tube, be provided with on the splint and press the handle, the handle on two splint deviates from each other, with the central spring of promotion splint compression, provides the space for the claw of mouse is visited into.

In this embodiment, press the handle including being fixed in an at least push rod on the splint, inner tube and urceolus are worn out in proper order to the push rod, the end of push rod is provided with handheld handle to in operation, the injury rodent is avoided to the control dynamics.

In this embodiment, a cover plate is arranged right above the spring, two ends of the cover plate are fixed to the top of the inner cylinder to prevent the hair or abdomen of the mouse from being clamped by the spring to cause damage, and the cover plate is made of plastic steel so as to facilitate water washing and keep the temperature of the abdomen of the mouse with a low heat transfer coefficient.

In this embodiment, the rubber pad is disposed on the surface of the inner cylinder opposite to the clamping plate, and the rubber pad is also disposed on the surface of the clamping plate opposite to the inner cylinder, so as to protect the mouse claw from being damaged.

In this embodiment, the elastic net mechanism includes a fine metal net for the mouse to grip, and a plurality of shaking springs are disposed on the circumference of the fine metal net, and the other ends of the shaking springs are fixed on the inner wall of the outer cylinder to achieve the tightness of the elastic net and leave a moving space for the mouse claw.
