Description

Technical Field

[0001] The utility model relates to the field of rat experimental equipment, in particular to a rat restraint bag. Background Art

[0002] When conducting experiments such as tail vein injection on rats, the rats need to be restrained first. Most traditional restraint methods are to place the rat inside a cylinder, expose the tail and then conduct experimental operations. However, since the cylinder has low elasticity and fixed size, it cannot adapt to rats of different sizes, and rats can easily move inside the cylinder, so restraining them is inconvenient, time-consuming and laborious, affecting the progress of the experiment.

[0016] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0017] In the description of the present invention, it should be noted that the terms "upper" and "lower" etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0018] like Figure 1 to Figure 2 As shown, the utility model provides a rat restraint bag for restraining rats during experiments. The rat restraint bag comprises a bag body 1, and the bag body 1 comprises two mutually connected and symmetrical bag surfaces 2. The bag body 1 is hollow inside for placing rats, and the two ends of the bag body 1 are respectively provided with a vent 3 and an opening 4 connected to the inside, and the length of the vent 3 is less than the length of the opening 4. When in use, the rat is placed in the bag body 1 from the opening 4, so that the head of the rat faces the vent 3 to facilitate the rat's breathing, and the tail is exposed from the opening 4, which is convenient for the rat's tail vein injection. The shape of the bag body 1 is trapezoidal, and a waist 5 inclined toward the opening 4 is provided on one side of the bag body 1 close to the vent 3, so as to fit the head of the rat and prevent the rat from moving significantly in the bag body 1. A folding portion 6 is provided near the opening 4 of the bag body 1, and the bag body 1 is folded at the folding portion 6 to adapt to the length of the rat. Two folding strips 7 are provided on the folding portion 6, and the folding strips 7 are made of metal. The two folding strips 7 are symmetrically arranged and connected to the bag surface 2 respectively, and the two folding strips 7 are parallel to the edge of the opening 4. The folding strips 7 can increase the stress, making it easier to open the opening 6 when in use, and also making it easier for the bag body 1 to be folded at the folding portion 6.

[0019] Further, the bag body 1 includes an upper bottom 8 and a lower bottom 9, the angle A between the extension line of the waist 5 and the extension line of the lower bottom 9 is 40-60 degrees, and the angle B between the waist 5 and the upper bottom 8 is 120-140 degrees. The length of the upper bottom 8 is 16-18 cm, the total length of the lower bottom 9 and the extension line of the lower bottom 9 is 27-29 cm, and the spacing between the upper bottom 8 and the lower bottom 9 is 12-13 cm. The size of the bag body 1 can be adjusted according to the size of the rat. The length of the folding strip 7 is 8-10 cm, the width of the folding strip 7 is 0.3-0.4 cm, the distance between the folding strip 7 and the upper bottom and the lower bottom is 1-2.5 cm, and the width of the folding portion 6 is 1 cm.

[0020] The best embodiment of the utility model is that the length of the upper bottom 8 of the bag body 1 is 17 cm, the total length of the lower bottom 9 and the extension line of the lower bottom 9 is 28 cm, the angle A between the extension line of the waist 5 and the extension line of the lower bottom 9 is 50 degrees, and the angle B between the waist 5 and the upper bottom 8 is 130 degrees. The bag body 1 can adapt to most rats.

[0021] The bag body 1 of the utility model is made of transparent EVA (ethylene-vinyl acetate copolymer) material, which can facilitate observation of the situation of the rat in the bag body 1.
