A mouse rewarming device

Abstract

This utility model discloses a mouse rewarming device, comprising: a resuscitation and rewarming unit, including multiple layers of rewarming components for rewarming multiple groups of mice, and a transfer component located on one side of the outlet of the rewarming components for transferring mice out of the rewarming components after rewarming and resuscitation; and a collection unit located at the outlet of the transfer components for accommodating mice that have escaped from the transfer components. The collection unit has multiple layers corresponding to the rewarming components. By placing mice requiring rewarming and rewarming within the rewarming components, with each group of mice placed in a corresponding layer within the rewarming components, the mice, after waking up, will move from the rewarming components to the transfer components, and then from the transfer components into the collection unit. This ensures that the layer in which the mice enter the collection unit is the same as the corresponding layer in the rewarming components, thereby automatically collecting the revived mice and preventing confusion between the collected groups of mice.

Description

Technical Field

[0001] This utility model relates to the field of mouse rewarming technology, specifically a mouse rewarming device. Background Technology

[0002] Mice are important scientific research animals. With the development of experimental techniques, many experiments involving long-term surgical procedures, such as the establishment of mouse cerebral artery embolism models and stereotactic injection into the brain, require general anesthesia of mice. Under normal physiological conditions, the body temperature of homeothermic animals is maintained in dynamic balance under the regulation of the hypothalamus. When the ambient temperature drops, mice will maintain their body temperature by curling up their abdomens to maintain normal physiological functions. After general anesthesia, mice become less sensitive to low-temperature environments, and mice under general anesthesia cannot produce self-protective postures to maintain body temperature. The core temperature of the body drops, and physiological functions are severely damaged. Especially when the experimental environment is low, it has a great adverse effect on the survival rate of mice and the surgical results. Therefore, after the operation of mice, it is necessary to rewarm them until they wake up.

[0003] Currently, there is no dedicated device for postoperative rewarming of mice. Typically, researchers place mice on a flat electric blanket for rewarming. Electric blankets are safe, convenient, and space-saving. However, when multiple mice have undergone surgery and are still unconscious, placing them all on an electric blanket can easily cause confusion between groups of mice. Furthermore, during the natural awakening process, researchers need to continuously monitor the mice, which takes a lot of time. If not careful, awakened mice may escape, causing a rodent infestation in the laboratory. Therefore, a mouse rewarming device has been designed to solve the above problems.

[0004] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Utility Model Content

[0005] The purpose of this invention is to provide a mouse rewarming device to solve the problems mentioned in the background art, such as the electric blankets used in the prior art being prone to mouse confusion when rewarming multiple unconscious mice, and the mice escaping during the rewarming process, causing a rodent infestation in the laboratory.

[0008] The rewarming unit includes a rewarming component with multiple layers for rewarming multiple groups of mice, and a transfer component located on one side of the outlet of the rewarming component for transferring the mice out of the rewarming component after rewarming and rewarming.

[0009] A collection unit, located at the outlet end of the transfer component, is used to contain mice that have escaped from the transfer component. The collection unit has multiple layers, corresponding one-to-one with the rewarming component.

[0010] Furthermore, the rewarming component includes:

[0019] The upper end of the thrust spring is pressed against the lower end of the limiting block to push the lower end of the conductive rod to separate from the energized rod.

[0020] Furthermore, the transfer component includes:

[0021] A transition frame is fixedly connected to the rear end of the front-mounted receiving cabinet. The transition frame is provided with transfer channels corresponding to the layers where the receiving slots are located, for transferring the awakened mice out of the receiving slots in each layer.

[0022] Multiple transition channels are provided, each corresponding to a transfer channel. The transition channels are connected to one end of the transition frame opposite to the front receiving cabinet, and are used to transfer mice in the transfer channels to the collection unit.

[0023] Furthermore, the collection unit includes:

[0024] The collection cabinet is fixedly connected to the outlet end of the transition channel;

[0025] The collection tank, which has multiple layers inside the collection cabinet and corresponds one-to-one with the transition channel, is used to collect mice transferred out of the transition channel.

[0026] The second cabinet door, located at the outlet end of the transition trough, is used to seal the mice inside the transition trough.

[0027] A one-way gate mechanism, located at the exit end of the transition channel, is used to block mice after they enter the collection tank.

[0028] Furthermore, the collection cabinet has an opening on the side corresponding to the one-way door mechanism to connect the collection trough with the transition channel;

[0029] The one-way door mechanism includes a rotating door for blocking the opening, and a limiting shaft is inserted into the upper part of the rotating door. The limiting shaft is fixedly connected to the side wall of the collection tank by a bracket.

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] Please see Figure 1-6 This utility model provides a technical solution:

[0043] A mouse rewarming device, comprising:

[0044] The awakening and rewarming unit 1 includes a rewarming component 11 with multiple layers for rewarming multiple groups of mice, and a transfer component 12 located on one side of the outlet of the rewarming component 11 for transferring the mice that have been rewarmed and awakened from the rewarming component 11 out of the rewarming component 11.

[0045] Collection unit 2, located at the outlet end of transfer component 12, is used to contain mice that have escaped from transfer component 12. Collection unit 2 has multiple layers corresponding to the rewarming component 11.

[0046] It should be noted that: the mice that need to be rewarmed are placed in the rewarming component 11, and each group of mice is placed in the corresponding layer of the rewarming component 11. After the mice are rewarmed, they will run from the rewarming component 11 to the transfer component 12, and then from the transfer component 12 into the collection unit 2, so that the layer in the collection unit 2 where the mice are located is the same as the corresponding layer in the rewarming component 11. This achieves automatic collection of the rewarmed mice, and the collection of mice from different groups can avoid confusion.

[0047] As an improvement, such as Figure 1-2As shown, the rewarming component 11 includes:

[0048] Front-mounted storage cabinet 111;

[0049] The receiving slot 112 is located inside the front receiving cabinet 111. The receiving slot 112 has multiple layers and multiple slots are provided at each time, for accommodating mice from different experimental groups waiting to wake up.

[0050] The first cabinet door 113 is located at the inlet end of the receiving groove 112 and is used to close the inlet of the receiving groove 112.

[0051] A heating pad 114 is disposed at the bottom of each of the receiving slots 112 for rewarming mice to be awakened.

[0052] Furthermore, such as Figure 2-3 As shown, a conductive rod 1141 for supplying power to the heating pad 114 is fixedly connected to the lower end of the heating pad 114, and a recess groove 1111 is provided at the bottom of the front receiving cabinet 111.

[0053] The conductive rod 1141 is slidably inserted into the retraction groove 1111;

[0054] A limiting block 1142 is fixedly sleeved on the outside of the conductive rod 1141 and inside the retraction groove 1111 for limiting the conductive rod 1141;

[0055] The lower end of the retraction groove 1111 is connected to a live rod 1144, and a thrust spring 1143 is sleeved on the outside of the live rod 1141 and inside the retraction groove 1111.

[0056] The upper end of the thrust spring 1143 is pressed against the lower end of the limiting block 1142, which is used to push the lower end of the conductive rod 1141 to separate from the energized rod 1144.

[0057] Furthermore, such as Figure 4-5 As shown, the transfer component 12 includes:

[0058] The transition frame 121 is fixedly connected to the rear end of the front receiving cabinet 111. The transition frame 121 is provided with a transfer channel 1211 corresponding to the layer where the receiving slot 112 is located, which is used to transfer the awakened mice out of the receiving slot 112 in each layer.

[0059] Multiple sets of transition channels 122 are provided, each corresponding to a transfer channel 1211. The transition channel 122 is connected to one end of the transition frame 121 opposite to the front receiving cabinet 111, and is used to transfer mice in the transfer channel 1211 into the collection unit 2.

[0060] As an improvement, such as Figure 5-6As shown, the collection unit 2 includes:

[0061] Collection cabinet 21 is fixedly connected to the outlet end of the transition channel 122;

[0062] The collection tank 23 has multiple layers inside the collection cabinet 21, which correspond one-to-one with the transition channel 122, and is used to collect mice transferred out of the transition channel 122.

[0063] The second cabinet door 22 is located at the outlet end of the transition groove and is used to seal the mice in the transition groove.

[0064] A one-way gate mechanism 25 is located at the exit end of the transition channel 122 and is used to block mice after they enter the collection tank 23.

[0065] Furthermore, such as Figure 6 As shown, the collection cabinet 21 has an opening 211 on the side corresponding to the one-way door mechanism 25, which is used to connect the collection trough 23 with the transition channel 122.

[0066] The one-way door mechanism 25 includes a rotating door 252 for blocking the opening 211. A limiting shaft 251 is rotatably inserted into the upper part of the rotating door 252. The limiting shaft 251 is fixedly connected to the side wall of the collection tank 23 by a bracket.

[0067] The width of the revolving door 252 is greater than the width of the opening 211.

[0068] Furthermore, a food placement slot 24 for holding mouse food is provided at the bottom of the collection slot 23 and near the second cabinet door 22;

[0069] The revolving door 252 has a through hole 253 inside, which is used to diffuse the smell of food in the food placement slot 24 into the transition channel 122.

[0070] It should be added that the front holding cabinet 111 and the collection cabinet 21 in this utility model have ventilation holes through the sides to prevent the mice from suffocating in the front holding cabinet 111 and the collection cabinet 21. In addition, the front holding cabinet 111, the collection cabinet 21 and the transition frame 121 in this utility model are preferably made of transparent material to facilitate observation of the mice's activity status after they wake up.

[0071] It should be noted that: in the specific implementation process of this utility model, if... Figure 1-3As shown, multiple mice required for rewarming in each experimental group are placed in the corresponding compartments 112, with the mice positioned on top of the heating pad 114. The first cabinet door 113 is closed, and the weight of the mice causes the heating pad 114 to move the conductive rod 1141 downwards. The conductive rod 1141 compresses the thrust spring 1143 downwards via the limiting block 1142, causing the conductive rod 1141, previously separated from the charged rod 1144, to now be in contact with it. At this time, the electrified rod 1144 transmits electricity to the heating pad 114 through the conductive rod 1141, so that the heating pad 114 heats and rewarms the mouse. After the mouse wakes up and runs out of the heating pad 114, the thrust spring 1143 pushes the limiting block 1142, so that the electrified rod 1144 separates from the conductive rod 1141, and the heating pad 114 stops heating. Thus, the heating pad 114 can automatically heat the mouse and automatically cut off the power, saving energy.

[0072] like Figure 4-6 As shown, after the mouse wakes up and runs out of the heating pad 114, it will smell the food in the food placement slot 24, causing the mouse to enter the collection slot 23 through the transfer channel 1211 and the transition channel 122 in sequence. When the mouse enters the collection slot 23 through the transition channel 122, the mouse will push the rotating door 252 to rotate around the limiting axis 251, causing the opening 211 to open. When the mouse enters the collection slot 23 and runs towards the food placement slot 24, the rotating door 252 will close the opening 211 again around the limiting axis 251 under the action of gravity, so that the mouse that has entered the collection slot 23 cannot return to the transition channel 122. This can automatically collect the mouse and prevent the mouse from escaping after waking up, thus avoiding a laboratory rodent infestation.

[0073] like Figure 4-5 As shown, when it is necessary to remove the mouse from the collection tank 23, simply open the second cabinet door 22 to remove the mouse from the collection tank 23;

[0074] like Figure 2 , Figure 5-6 As shown, this invention ensures that mice from different experimental groups can be placed in the corresponding number of layers of the collection tank 23, the transition channel 122, and the receiving tank 112 by setting the number of layers accordingly, thus avoiding confusion between mice from different groups.
