Abstract
Description
Technical Field
[0001] This utility model belongs to the field of laboratory animal equipment, and in particular relates to a guinea pig restraint frame. Background Technology
[0002] In scientific research and teaching experiments, especially in the development of medical devices and biomedicine, a large amount of basic research and experiments must be carried out. However, due to strict legal and ethical restrictions, it is difficult to conduct live human experiments. Such research and experiments can only be carried out using live laboratory animals. Since the gene sequence of guinea pigs is very similar to that of humans, guinea pigs are often used as laboratory animals in medical experiments.
[0003] Intravenous injections, blood sampling, and skin stimulation are common experimental procedures involving guinea pigs. Regardless of the method, the guinea pig must be securely restrained to ensure the experiment's success. However, guinea pigs are naturally active, and their claws are particularly sharp, making them difficult to control and prone to injuring experimenters. This significantly increases the difficulty and reduces efficiency of the experiments. Furthermore, once restrained, different parts of the guinea pig need to be manipulated, but since they cannot be moved, experimenters must place them at different heights or change their experimental positions according to the requirements, which is quite cumbersome.
[0004] Therefore, there is an urgent need for a guinea pig restraint system that can safely and stably restrain guinea pigs and facilitate the smooth conduct of guinea pig experiments. Utility Model Content
[0005] To address the shortcomings of existing technologies, this invention provides a guinea pig restraint frame that can safely and stably secure guinea pigs. This invention reduces the risks associated with restraining guinea pigs and prevents laboratory personnel from being scratched by them. Simultaneously, it significantly improves the efficiency of guinea pig experiments and reduces the workload of staff.
[0006] This utility model is implemented as follows: a fixing frame for laboratory guinea pigs includes a base plate, an operating table is provided above the base plate, and an adjustment frame is provided between the base plate and the operating table.

The clamp structure is set at the bottom of the operating table 5 and is composed of two oppositely arranged circular ring structures. The two circular ring structures can move relative to each other. When they are in contact, they form a clamp structure located below the adjustment hole 10. The internal diameter of the clamp structure is smaller than the diameter of the adjustment hole 10, so that the guinea pig's limbs can pass through and be fixed.
[0035] The control panel 5 is also equipped with an elastic band fixing frame 9, which is equipped with an elastic band to fix the guinea pig's body. The position of the elastic band fixing frame 9 is set according to actual needs, for example, it can be set on the outside of the control panel 5, and the number of elastic band fixing frames 9 can be two or more.
[0036] The adjustment frame includes two first supports 2 and two second supports 6. The two first supports 2 are arranged opposite each other, and the two second supports 6 are arranged opposite each other. The top of the first support 2 is fixed to the bottom of the operating table 5, and the bottom is fixed to the base plate 1. A hinged support is provided between the two first supports 2. The hinged support includes a connecting rod 3 and a sliding rod 4.
