Description

Technical Field

[0001] The utility model relates to the technical field of biomedical research, in particular to a cage for rat injection. Background Art

[0002] In the field of biomedical research, rats are commonly used as experimental animals and are widely used in drug screening, physiological and pathological research, gene function analysis, etc. In these studies, intraperitoneal injection and anesthesia are common experimental operations.

[0003] Traditional rat intraperitoneal injection or anesthesia operations usually place the rat on an open operating table, and the experimenter manually fixes the rat for injection. However, this method has many shortcomings. First, rats often have strong stress reactions during the injection process, such as struggling, screaming, etc., which not only increases the difficulty of the experimental operation, but also may affect the accuracy of the experimental results. Secondly, because rats have sharp teeth, experimenters are prone to bites during the operation, which not only causes physical harm to the experimenters, but also may cause psychological fear and resistance. Therefore, in order to solve the above problems, we propose a cage for rat injection. Utility Model Content

[0004] The utility model aims to solve the defects in the prior art and provides a cage for rat injection.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] Furthermore, an abdominal support bar is fixedly installed on the rear side of the cage body, and the abdominal support bar is an arc-shaped structure. A through groove is opened on one side of the cage body, and the through groove is connected to the arc-shaped opening. The through groove is located on one side above the abdominal support bar.

[0008] Furthermore, the bottom of the cage body is composed of a plurality of bottom cross bars installed at equal distances.

[0009] Furthermore, the tail fixing assembly includes a mounting plate, which is obliquely installed inside the mounting frame, and a plurality of slots are equidistantly provided on one side of the inside of the mounting plate. A pressing plate is rotatably installed on one side of the top of the mounting plate, and a plurality of arc-shaped clamping strips are equidistantly fixedly installed on one side of the pressing plate, and the plurality of arc-shaped clamping strips are adapted and correspond to the plurality of slots.

[0010] Furthermore, two special-shaped springs are fixedly installed between the pressing plate and the mounting plate.

[0011] Furthermore, anti-skid pads are provided on the top of the mounting plate and on one side of the arc-shaped clamping strip close to the top of the mounting plate.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The utility model can reduce the stress response of rats and protect experimenters from harm. The tail fixing component of the utility model can effectively fix the tail of the rat, lift the rear part of the rat, and expose the abdomen of the rat, which is convenient for experimenters to perform injections. It can effectively assist experimenters in performing intraperitoneal injections or anesthesia on rats, avoid the struggle of rats and bite experimenters during the injection process, and improve the accuracy and safety of experimental operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 3 It is a top view of the utility model.

[0018] In the figure: 1, cage body; 2, arc-shaped opening; 3, tail fixing assembly; 4, belly support bar; 5, bottom cross bar; 6, mounting frame; 7, mounting plate; 8, slot; 9, arc-shaped clamping strip; 10, special-shaped spring; 11, pressing plate; 12, through slot. DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0020] Reference Figure 1-3A cage for rat injection includes a cage body 1, the front and rear sides of the cage body 1 are both open structures, an arc-shaped opening 2 is opened on the rear side of the top of the cage body 1, a mounting frame 6 is fixedly installed on the rear side of the top of the cage body 1, and an inclined tail fixing component 3 is fixedly installed on one side inside the mounting frame 6, and the tail fixing component 3 is located above the rear side of the arc-shaped opening 2.

[0021] When performing intraperitoneal injection on rats, the rats can be first put into the cage 1. The cage 1 can be made into various specifications to adapt to rats of different body shapes, so that the rats can only have a small struggling space after entering the cage 1. After the rats are put in, the tails of the rats can be lifted to make the abdomen of the rats tilt upwards, and the tail fixing component 3 can be used to clamp the tail of the rats to keep the rats in the lifted state, and the abdomen of the rats will face the rear side of the cage 1, which is convenient for the experimenter to perform injection;

[0022] The bottom of the cage 1 is composed of a plurality of bottom cross bars 5 installed at equal intervals. When the rat's tail is lifted, the rat will struggle and flee forward due to its own habits. At this time, the rat's front paws will grasp the cross bar at the bottom of the cage 1, and the internal space of the cage 1 does not have the conditions for the rat to turn around, so the rat's struggling amplitude will be effectively reduced, making it easier for the experimenter to perform the injection.

[0023] An abdominal support bar 4 is fixedly installed on the rear side of the cage body 1. The abdominal support bar 4 is an arc-shaped structure. A through groove 12 is opened on one side of the cage body 1. The through groove 12 is connected to the arc-shaped opening 2. The through groove 12 is located on one side above the abdominal support bar 4.

[0024] The abdomen of the rat can be supported by the abdomen support bar 4, which can improve the stability of the abdomen of the rat; when placing the rat into the cage 1, the rat's tail can be first lifted and placed in the through groove 12. By pulling the rat's tail, the rat can be dragged into the cage 1, thereby effectively avoiding biting the experimenter in the process of placing the rat into the cage 1.

[0025] The tail fixing assembly 3 includes a mounting plate 7, which is tiltedly mounted inside the mounting frame 6. A plurality of slots 8 are evenly spaced on one side of the mounting plate 7. A pressing plate 11 is rotatably mounted on one side of the top of the mounting plate 7. A plurality of arc-shaped clamping strips 9 are evenly and fixedly mounted on one side of the pressing plate 11. The plurality of arc-shaped clamping strips 9 are adapted and correspond to the plurality of slots 8. Two special-shaped springs 10 are fixedly mounted between the pressing plate 11 and the mounting plate 7. Anti-skid pads are attached to the top of the mounting plate 7 and to the side of the arc-shaped clamping strip 9 close to the top of the mounting plate 7.

[0026] The tail fixing assembly 3 can be used to fix the back of the rat. The test personnel can press down the pressing plate 11 to rotate the arc-shaped clamping strip 9 on one side of the pressing plate 11 and move it out of the slot 8. At this time, the rat's tail is placed between the arc-shaped clamping strip 9 and the mounting plate 7. Then, the pressing plate 11 is slowly released. The pressing plate 11 and the arc-shaped clamping strip 9 will be reset under the action of the special-shaped spring 10. The rat's tail will be clamped and fixed by the arc-shaped clamping strip 9 and the mounting plate 7, so that the rear of the rat can be lifted and the abdomen of the rat can be exposed. The anti-slip pad can be provided to increase the friction between the coccyx fixing assembly 3 and the rat's tail, which can prevent the rat's tail from detaching therefrom and reduce damage to the rat's tail.
