Description

Technical Field

[0001] This utility model relates to the field of animal experiments, and more specifically to a postoperative rehabilitation device for non-human primate laboratory animals. Background Technology

[0002] Currently, in the postoperative management of non-human primates undergoing neurosurgery or cranial surgery, it is common for animals to interfere with the wound due to their own behavior. Although pain can be relieved with analgesics postoperatively, non-human primates may still frequently touch the head wound area with their hands or feet due to instinctive drive and exploratory behavior, leading to tearing of sutures, wound contamination, or even infection. Existing techniques typically rely on physical isolation methods such as external dressings, collars, or restraints. However, because non-human primates possess strong grasping and removal abilities, traditional protective measures are often difficult to secure effectively, resulting in poor protective effect and insufficient continuity, failing to meet the actual needs of wound protection during postoperative recovery.

[0003] Therefore, there is currently a lack of a rehabilitation and protective device in the field that can effectively restrict head contact behavior, reduce the risk of infection, and be suitable for long-term postoperative management while ensuring the basic freedom of movement of laboratory animals. Summary of the Invention

[0004] The purpose of this invention is to provide a postoperative rehabilitation device for non-human primate laboratory animals, which can effectively prevent primate laboratory animals from touching their head wounds with their hands or feet while ensuring a certain degree of freedom of movement, thereby significantly reducing the risk of postoperative infection and promoting wound healing.

[0053] The main advantages of this utility model include:

[0054] (a) A head isolation plate with a rotating neck plate and neck opening is installed, allowing the animal's head to protrude and suspend above the plate while remaining out of reach of the hands. This effectively prevents the animal from scratching the postoperative wound while ensuring that the animal can rotate to a certain extent, thus reducing the risk of infection. The head isolation plate also improves the animal's comfort and adaptability through its rotatable structure, which is superior to traditional methods of forced restraint.

[0055] (b) The animal standing and handling environment has been further optimized. The U-shaped first panel opening structure and the second panel below it facilitate animals to sit or stand, increasing the animals' natural posture selection space; the movable windows on the side panels allow researchers to complete necessary experimental or care operations without disturbing the animal's overall posture, improving operational efficiency and animal welfare.

[0056] (c) The drinking device and top plate structure located above the head isolation plate ensure that the animal can still obtain basic physiological needs such as drinking water while in a fixed position, enhancing the adaptability of the equipment for long-term rehabilitation use. The drinking device is supported by a column and its position is adjustable to facilitate adaptation to different animals.

[0057] (d) The compression device in the enclosed space makes it easy to adjust the range of motion according to the size of the animal or the needs of the operation, and assists in completing operations such as fixation or medication; the waste collection container helps to collect excrement in a timely manner and keep the experimental environment clean; the moving device and side handle make the whole equipment easy to move and position in the laboratory, improving the practicality and ease of operation of the equipment.

[0058] Based on the above structure, this utility model can effectively meet multiple needs for the safety management, convenient care, and animal welfare protection of non-human primates during postoperative recovery.

[0059] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, the accompanying drawings are schematic diagrams, and therefore the apparatus and device of the present invention are not limited to the size or scale of the schematic diagrams.

[0060] Example

[0061] This embodiment provides a postoperative rehabilitation device for non-human primate laboratory animals, including: a side plate 1, a first plate 2, a head isolation plate 3, a squeezing device 12, a movable structure, a waste collection container 13, an activity window 8, a drinking device 9, and a protective ceiling, etc., which aims to provide a safe, stable, and controllable activity environment for primates during postoperative rehabilitation.

[0062] The head isolation plate 3 includes a rotating neck plate 4 and a fixing plate 5 attached to its periphery. The rotating neck plate 4 is used to attach an animal's neck collar, allowing it to rotate around its axis. After the collar is connected to the rotating neck plate 4, the animal's head protrudes above and outside the head isolation plate 3, allowing the animal to move in a circle around its own axis or around the rotating neck plate 4, thus retaining a certain degree of freedom of movement and avoiding pressure injuries or behavioral disorders caused by prolonged fixation.

[0063] The first board 2 has an opening at the front, forming a U-shaped structure, where the animal can stand or sit. Below the first board 2 is a second board 7 serving as a support platform, which, together with compression devices 12 located on both sides, restrains the animal's position. The compression devices 12 are controlled by a connected handle 17, allowing the animal to be confined to the front of the first board 2 (chair) as needed, facilitating procedures such as injections and oral medication administration. They also support adjustable activity space to adapt to the management needs of different rehabilitation stages.

[0064] To meet the natural behavior and care needs of laboratory animals, the front side panel 1 has two small movable windows 8, and each of the two side panels 1 has a large window. All windows are equipped with a double safety locking structure to ensure convenient operation while preventing animal escape. The drinking device 9 is located on the column above the head isolation panel 3 and can be adjusted or removed as needed to meet the basic physiological drinking needs of animals and also facilitate special medical control.

[0065] The equipment is equipped with four rotatable silent wheels at the bottom, each with a locking mechanism. Combined with the handle 16 at the rear of the equipment, this allows the entire set of equipment to move and position smoothly and quietly in different experimental environments. Below the second plate 7, there is also a waste collection container 13, which is detachable for easy regular cleaning, ensuring environmental hygiene and suitable for long-term use.

[0066] To prevent environmental interference to the exposed parts of the animal's head, a protective top plate 11 is installed above the rotating neck plate 4. It is made of high-quality acrylic glass, which is transparent and durable. It can block airflow and dust while maintaining a clear field of vision, making it easy to observe the animal's condition.

[0067] It should be noted that in the claims and specification of this patent, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one" does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
