Description

Technical Field

[0001] This invention relates to the field of experimental equipment technology, and in particular to a portable detection device for detecting small animal back climbing. Background Technology

[0002] Low back pain is a common chronic pain caused by intervertebral disc degeneration and soft tissue injury in the lower back. Early research mainly focused on large animals, but this was costly and time-consuming. In recent years, more and more animal models of low back pain have been used, but effective methods for behavioral assessment are still lacking.

[0003] Current behavioral tests for back pain in mice commonly use the Von Frey mechanical pain sensitivity test and passive gait analysis. The former is subject to strong subjective judgment, while the latter relies on a treadle to force the mouse to move. The detection effect is not good when the mouse has significant back pain symptoms. Therefore, there is currently a lack of dedicated equipment that can detect back pain behavior based on the animal's willingness to move voluntarily.

[0004] In view of this, the present invention provides a portable small animal back climbing detection device that rapidly and directly reflects the threshold level of back pain in mice without human interference. Summary of the Invention

[0005] To address the aforementioned problems, this invention proposes a portable detection device for detecting small animals climbing on their backs and waists.

[0006] This invention is achieved through the following technical solution: This invention proposes a portable small animal back climbing detection device, comprising a triggering device, a climbing frame, and an observation cover, wherein: The triggering device includes a timer and a sensing component. The triggering device is located at a certain distance from the sensing component. The triggering device is located at the bottom of the climbing frame and is fixed to it by the observation cover. The triggering device includes a triggerable sensing plate. The triggering device is used to control the timer to stop after the triggerable sensing plate is triggered.

[0007] Furthermore, the triggering device also includes a base plate located at the bottom of the triggerable sensing plate, and the base plate is fixedly connected to the observation cover.

[0008] Furthermore, the triggering device also includes a reinforcing rod, and the bottom of the triggerable sensing plate is provided with a triggerable sensing groove, the groove cooperating with the reinforcing rod, the reinforcing rod being arranged horizontally and its two ends being rotatably connected to the observation cover, so that the triggerable sensing plate and the base plate have a certain angle.

[0009] Furthermore, both the base plate and the triggerable sensing plate are provided with magnets, and one side of the base plate and one side of the triggerable sensing plate are attracted by the magnets.

[0010] Furthermore, the observation cover is composed of multiple acrylic plates connected together, and the observation cover has a missing surface.

[0011] The beneficial effects of this invention are: (1) The portable small animal back climbing detection device proposed in this invention uses a climbing frame in conjunction with a triggerable sensor plate and a timer to detect the behavior of small animals. The device is more compact and lightweight. At the same time, it can avoid the traditional passive detection of back pain values ​​in a specific machine, which is not a spontaneous behavior of small animals, and can directly reflect the threshold level of back pain in animals.

[0012] (2) The portable small animal back climbing detection device proposed in this invention uses a timer, a base plate and a triggerable sensor plate to form a triggering device. When the small animal falls from the climbing frame, it will land on the triggerable sensor plate, causing the magnet on the base plate to detach from the magnet on the triggerable sensor plate. The timer stops timing after the magnet detaches from the magnet. The timing is stopped by the animal falling, which can avoid human timing error. The timing stops more accurately the moment the magnet detaches from the magnet. Attached Figure Description

The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0014] To more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0015] Please refer to Figures 1-4 This invention proposes a portable small animal back climbing detection device, comprising a triggering device, a climbing frame 1, and an observation cover 2, wherein: The triggering device includes a timer 6 and a sensing component. The triggering device is a certain distance away from the sensing component. The triggering device is located at the bottom of the climbing frame 1 and is fixed to it by the observation cover 2. The triggering device includes a triggerable sensing plate 4. The triggering device is used to control the timer 6 to stop after the triggerable sensing plate 4 is triggered.

[0016] Specifically, the back pain model severely affects the motor abilities of mice, primarily through climbing and grasping. The duration and distance the animal spends climbing on the climbing frame 1 are measured. One animal with back pain and one with normal back pain are placed in the device, and timer 6 is activated. When the animal falls, a triggerable sensor 4 is activated, stopping timer 6. The pain threshold of the animal with back pain is compared by comparing the climbing time of the two animals. This invention utilizes the climbing frame 1 in conjunction with the triggerable sensor 4 and timer 6 to detect animal behavior. The device is more compact and lightweight, and it avoids the traditional passive detection of back pain values ​​in specific machines, which is not based on spontaneous animal behavior. This invention is applicable to back pain detection in small, climbing animals such as mice, tree shrews, and marmosets.

[0017] Furthermore, the triggering device also includes a base plate 5, which is located at the bottom of the triggerable sensing plate 4 and is fixedly connected to the observation cover 2.

[0018] Specifically, the base plate 5, the observation hood 2, and the climbing frame 1 form a semi-enclosed space. The base plate 5 is used to support the bottom and also forms a triggering device.

[0019] Furthermore, the triggering device also includes a reinforcing rod 3, and the bottom of the triggerable sensing plate 4 is provided with a triggerable sensing groove 8. The groove cooperates with the reinforcing rod, and the reinforcing rod 3 is arranged horizontally and its two ends are rotatably connected to the observation cover 2, so that the triggerable sensing plate 4 and the base plate 5 have a certain angle.

[0020] Specifically, the reinforcing rod 3 is set horizontally, and the triggerable sensing groove 8 is attached to the reinforcing rod 3. The two sides of the reinforcing rod 3 are connected to the observation cover 2. The reinforcing rod 3 can rotate and drive the triggerable sensing plate 4 to rotate. During the experiment, the triggerable sensing plate 4 can be rotated to adjust to the triggerable state.

[0021] Furthermore, both the base plate 5 and the triggerable sensing plate 4 are provided with magnets 7, and one side of the base plate 5 and one side of the triggerable sensing plate 4 are attracted by the magnets 7.

[0022] Specifically, the magnet 7 is attracted to one side, forming an angled structure between the base plate 5 and the triggerable sensor plate 4. When a small animal falls from the climbing frame 1, it will land on the triggerable sensor plate 4, causing the magnet 7 on the base plate 5 to detach from the magnet 7 on the triggerable sensor plate 4. The timer 6 stops timing after the magnet 7 detaches from the magnet. The timing is stopped by the animal falling, which avoids human timing errors. The timing stops more accurately the moment the magnet detaches from the magnet.

[0023] Furthermore, the observation cover 2 is composed of multiple acrylic plates connected together, and the observation cover 2 has a blank surface.

[0024] Specifically, taking a quadrilateral testing device as an example, acrylic plates are set on the left, right and rear sides of the base plate 5, with a notch on the front to place experimental animals.

[0025] In practical use, the triggerable sensor plate 4 inside the device is adjusted to the triggerable state, that is, the magnet 7 is attracted and forms a suspended style through the reinforcing rod 3. Then, two animals are prepared, one with back pain and the other with normal back pain. The two animals are placed in the device. When the animals are climbing on the climbing frame 1, the timer 6 is pressed to record the duration. When the animals fall, they will fall onto the triggerable sensor plate 4, causing the magnet 7 to detach and the timer 6 to stop automatically. The pain threshold of the animal with back pain is compared by comparing the climbing time of the two animals.

[0026] Of course, the present invention may have many other embodiments. Based on this embodiment, other embodiments obtained by those skilled in the art without any creative effort are all within the scope of protection of the present invention.
