Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of rat tail vein injection, and particularly relates to an animal restraint bag for rat tail vein injection. Background Art
[0002] In basic medical research and preclinical drug development, mice are widely used to observe the pharmacotoxicology of drugs and new compounds, as well as to study the etiology, pathogenesis, and pathology of diseases. These studies often require specific drug delivery methods, with tail vein injection being one of the most commonly used due to its high efficiency and direct effect on the circulatory system. However, existing methods for securing the mouse's tail, typically using a caging device or manual restraint, can cause the mouse to struggle during tail vein injection, resulting in insecure fixation and potentially leading to injection failure. Utility Model Content
[0003] Therefore, the utility model aims to solve the problem of unstable fixation in the prior art.
[0004] To this end, the technical solution adopted is that the utility model is an animal restraint bag for intravenous injection of drug administration into the rat tail, comprising: a bag body, the bag body is connected to one end of the sleeve, the other end of the sleeve is connected to the large diameter end of the conical tightening sleeve, the small diameter end of the conical tightening sleeve is provided with multiple openings at intervals along the circumferential direction, an adjusting tube is sleeved on the outer wall of the sleeve, one end of the adjusting tube is threadedly connected to the outer wall of the sleeve, a circular ring is provided on the inner wall of the other end of the adjusting tube, and the conical tightening sleeve is located inside the circular ring.
[0005] Preferably, the small diameter end of the conical tightening sleeve is provided with four openings at intervals along the circumferential direction.
[0006] Preferably, anti-slip grooves are provided on the outer wall of the adjustment tube.
[0007] Preferably, a base is provided on the outer wall of the sleeve, and a suction cup is provided on the base.
[0008] Preferably, a flexible pad is provided on the inner wall of the conical tightening sleeve.
[0009] Preferably, the bag body is conical.
[0010] The technical solution of the utility model has the following advantages: the tightening force during fixation can be adjusted by rotating the adjustment tube, so that the mouse's tail can be fixed for tail injection and medication. Since the diameter of the conical tightening sleeve can be adjusted, the tails of mice of different sizes can be fixed.
[0011] Other features and advantages of the present invention will be described in the following description, and in part will become apparent from the description, or will be understood by practicing the present invention. The purpose and other advantages of the present invention can be achieved and obtained by the structures particularly pointed out in the written description and the accompanying drawings.
[0012] The technical solution of the present invention is further described in detail below through the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] The accompanying drawings are used to provide a further understanding of the present invention and constitute a part of the specification. Together with the embodiments of the present invention, they are used to explain the present invention and do not constitute a limitation of the present invention. In the accompanying drawings:

[0017] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0018] It should be noted that when a component is referred to as being “fixed to” or “disposed on” another component, it can be directly on the other component or indirectly on the other component. When a component is referred to as being “connected to” another component, it can be directly or indirectly connected to the other component.
[0019] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship 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 orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0020] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.
[0021] The utility model provides an animal restraint bag for mouse tail vein injection. Figure 1-2 As shown, it includes: a bag body 1, which is connected to one end of a sleeve 2, the other end of which is connected to the large-diameter end of a tapered tightening sleeve 3. The small-diameter end of the tapered tightening sleeve 3 is provided with multiple openings 4 spaced circumferentially. An adjustment tube 5 is sleeved on the outer wall of the sleeve 2. One end of the adjustment tube 5 is threadedly connected to the outer wall of the sleeve 2. A ring 6 is provided on the inner wall of the other end of the adjustment tube 5, and the tapered tightening sleeve 3 is located inside the ring 6. The tapered tightening sleeve 3 is made of an elastic material, such as thermoplastic polyurethane.
[0022] The working principle and beneficial technical effects of the above technical solution are as follows: the mouse's head is placed in the bag body 1, the body is located in the sleeve 2, the tail is located in the conical tightening sleeve 3, and the tail is located outside the conical tightening sleeve 3. The adjusting tube 5 is rotated to move the adjusting tube 5 to the right, and the ring 6 moves to the right to tighten the conical tightening sleeve 3. Through elastic deformation, the gap of the opening 4 becomes smaller, thereby fixing the mouse's tail. The tightening force during fixation can be adjusted by rotating the adjusting tube 5, so that the mouse's tail can be fixed for tail injection. Since the diameter of the conical tightening sleeve 3 can be adjusted, the tails of mice of different sizes can be fixed.
[0023] In one embodiment, the small diameter end of the conical tightening sleeve 3 is provided with four openings 4 at intervals along the circumferential direction to facilitate processing and manufacturing. The outer wall of the adjusting tube 5 is provided with anti-slip grooves to increase friction and facilitate the person to hold the adjusting tube. A base 7 is provided on the outer wall of the sleeve 2, and a suction cup 8 is provided on the base 7. The suction force of the suction cup 8 facilitates the fixing or disassembly of the sleeve 2. A flexible pad is provided on the inner wall of the conical tightening sleeve 3 to reduce damage to the mouse's body caused by pressure so that it can be reused. The bag body 1 is conical, so that the mouse's head can have more room to move, reducing the struggle and anxiety of the mouse during tail injection.
[0024] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
