Description

TECHNICAL FIELD

[0001] The present application relates to a medical experimental equipment, in particular to a medical experimental large mammal fixing stretcher. BACKGROUND

[0002] In the field of life science research, we usually need to use some mammals, such as mice, rats, rabbits, pigs and macaques. Among them, small mammals such as mice, rats and rabbits are relatively easy to fix in the laboratory and are not easy to escape after being fixed. Even if they escape, they are easy to control. However, compared with small mammals such as mice, rats and rabbits, large mammals such as pigs and macaques face many problems during experiments. The present application is to solve the problems faced by large mammals and to ensure the smooth completion of experiments.

[0003] This medical experimental large mammal fixing stretcher mainly considers the following problems faced in the experimental process: 1. Generally, large mammals are large in size and weight, and it is not convenient to move them from the cage to the experimental table, so a medical experimental large mammal fixing stretcher is needed; 2. Generally, large mammals are large in size and weight, and if the anesthetic state cannot be maintained after using anesthetic drugs for anesthesia, the experimental animals, laboratory property and experimental personnel may be injured if the anesthesia fails unexpectedly, which may cause adverse consequences that are difficult to estimate, so a medical experimental large mammal fixing stretcher is needed; 3. Generally, large mammals are large in size and weight, and in the process of experiments, the material firmness of the stretcher itself needs to be considered, and some clinical experiments require perfect CT examination and magnetic resonance imaging (MRI) examination, especially the fixed plate material of magnetic resonance imaging (MRI) examination cannot contain ferromagnetic or conductive metal objects, so a medical experimental large mammal fixing stretcher is needed; 4. Generally, large mammals are used for some clinical experiments, such as large artery and vein puncture, laparotomy surgery, thoracotomy surgery and other surgical operations, which require flexible fixing points, so a medical experimental large mammal fixing stretcher is needed; 5. Generally, during the use of large mammals, it is not possible to use one fixing stretcher for one large mammal, which is economically poor for experimenters, so this medical experimental large mammal fixing stretcher needs to better adapt to different types and sizes of large mammals, so a medical experimental large mammal fixing stretcher is needed.
