Description

Technical Field

[0001] The invention relates to the technical field of animal weightlessness experiments, and in particular to a wearable suspension device for animal weightlessness experiments. Background Art

[0002] In life science research, it is often necessary to keep experimental animals in a specific posture for observation, study or handling. Since animals are naturally active and difficult to control, researchers need to use restraints that can limit the body movement of animals to a certain extent to achieve the purpose of controlling animals. In simulated weightlessness research, in order to simulate the effects of microgravity on experimental animals, a specific suspension restraint system is particularly needed.

[0003] At present, the tail suspension model is mostly used in animal experiments simulating microgravity. In this traditional tail suspension model, the tail binding material often falls off due to excessive struggling of the animals, and researchers need to repeatedly perform the tail binding operation, which is not conducive to long-term research. In addition, the unstable suspension angle in the traditional tail suspension model is also a key problem that technicians in this field need to solve urgently. Some researchers use the method of threading the tail with a wire to reduce the problem of repeated binding, but this can easily cause systemic inflammation and affect the research results. In severe cases, it can cause the tail to break, and subsequent scientific research cannot be carried out. At the same time, this model also has problems such as low research efficiency, inability to collect animal physiological data in real time, and limited animal diet and water supply.

[0004] In view of this, the existing technology still needs to be improved and developed. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a wearable suspension device for animal weightlessness experiments, aiming to solve the problem that animal experiments simulating microgravity use a microgravity suspension method, but there is instability and in severe cases it will make the experiment impossible.

[0061] In view of the shortcomings of the prior art, this embodiment provides a wearable suspension device for animal weightlessness experiments, which can be specifically referred to as follows:

[0062] As attached Figure 1 , Attachment Figure 4 and attached Figure 5 As shown, a wearable suspension device for animal weightlessness experiments includes a suspension bracket 1, an I-shaped restraint garment 2 and a plurality of metal chains 3. The suspension bracket 1 is composed of a plurality of metal rods. A placement cavity is provided inside the suspension bracket 1. The placement cavity is used to place the experimental animal, and the experimental animal can move in the placement cavity. Specifically, the experimental animal is wrapped with an I-shaped restraint garment 2, and the I-shaped restraint garment 2 is wrapped around the abdomen of the experimental animal to fix the experimental animal. A plurality of metal chains 3 are also provided on the I-shaped restraint garment 2, one end of the metal chain 3 is provided on the top of the suspension bracket 1, and the other end is provided on the I-shaped restraint garment 2. By adjusting the length of the metal chain 3, the experimental animal can be suspended in the placement cavity to facilitate subsequent experiments.

[0063] As attached Figure 7As shown, the suspension bracket 1 can be connected to an external rotating device. Through the rotation, a weightlessness experiment can be simulated for experimental animals. The suspension bracket 1 is fan-shaped as a whole. Multiple suspension brackets 1 can be arranged adjacent to each other to form a circle, and experiments can be carried out on multiple experimental animals simultaneously, effectively improving the experimental efficiency.

[0064] At least two metal chains 3 are arranged on the I-shaped restraint garment 2, preferably four metal chains 3, with a metal chain 3 arranged on both sides of the tail and the head of the experimental animal. The angle of the experimental animal can be adjusted through the four metal chains 3 to facilitate the experiment and improve the stability of the experiment.

[0065] In this embodiment, the suspension device is used to simulate the whole-body and long-term suspension of rodent experimental animals (such as mice) during weightlessness training. The I-shaped restraint clothing 2 is made of soft material to ensure a gentle and soft restraint process for the animal, and the suspension bracket 1 is made of metal material.

[0066] Furthermore, the I-shaped restraining garment 2 can be made of elastic fabric.

[0067] In one embodiment of the present application, the metal chain 3 includes a plurality of chain links and two red buckles (not shown in the figure), and the plurality of chain links are arranged in sequence in a buckle shape, that is, the plurality of chain links are buckled together in sequence from top to bottom to form a chain, and the two adjacent chain links are detachably arranged; the length of the two chain links located at the head of the experimental animal is greater than the length of the chain link located at the tail of the experimental animal, so that the head of the experimental animal is lower than the tail, so as to facilitate the experiment; a red buckle is provided at each end of the chain formed by the plurality of chain links, and the red buckle is a prior art. The red buckle and the key chain have the same principle, that is, an opening is provided on one side thereof, and a closing member is rotated on one side of the opening, and the closing member is rotatably arranged at the opening by a torsion spring, and the opening can be opened by pressing the closing member; or the red buckle as a whole is formed into a closed annular member by bending, and the bending part has the ability of elastic deformation, and is sealed by abutting the two ends, and can also be opened by squeezing one end located inside, elastically deforming, and returning to the initial state after release, and continuing to close;

[0068] The red buckle at the top of the chain is buckled with the hanging bracket 1, that is, it is hung on the hanging bracket 1 through the red buckle, and the other end is buckled with the chain ring at the top of the chain; the red buckle at the bottom of the chain is buckled with the I-shaped restraining garment 2; thus, the experimental animal can be hung in the placement cavity through the metal chain 3 to facilitate observation and testing.

[0069] A connecting seam is provided on the chain link. By opening or closing the connecting seam, the entire chain can be disassembled and added, thereby changing the length of the metal chain 3 to adjust the angle of the body of the experimental animal; at the same time, the distance between the bottom of the metal chain 3 and the suspension bracket 1 can be shortened by changing the buckling position of the hook.

[0070] In one embodiment of the present application, as shown in the attached Figure 4 As shown, the I-shaped restraining garment 2 includes a wrapping portion 21, two first fixing portions 22, two second fixing portions 23 and a pocket 24. The wrapping portion 21 is rectangular and is provided with four through holes, which are respectively located at the four corners of the wrapping portion 21. The red buckle is connected to the side wall of the wrapping portion 21 through the through holes to lift the I-shaped restraining garment 2; two first fixing portions 22 and two second fixing portions 23 are respectively provided on both sides of the wrapping portion 21, the first fixing portions 22 and the second fixing portions 23 correspond one to one, and are located at the same end of the wrapping portion 21, the first fixing portions 22 and the second fixing portions 23 cooperate with each other to wrap the abdomen of the experimental animal; a pocket 24 is also provided on the outer surface of the wrapping portion 21, and the pocket 24 is used to place an experimental sensor for detecting the data of the experimental animal.

[0071] Specifically, the experimental sensor is first placed in the pocket 24, and then the wrapping part 21 is spread from the back of the experimental animal to both sides and wrapped around the abdomen of the experimental animal. The first fixing part 22 and the second fixing part 23 at both ends are intertwined, and the first fixing part 22 and the second fixing part 23 cooperate to restrain the wrapping part 21, so that the wrapping part 21 can firmly wrap the experimental animal to prevent the experimental animal from falling during the experiment, and then the experiment can be carried out.

[0072] The experimental sensor may be a photoelectric sensor, a light-sensitive sensor, a thermistor sensor, etc., so as to detect various vital sign parameters of the experimental animal, including but not limited to heartbeat or blood pressure, through the experimental sensor.

[0073] In this embodiment, the pocket 24 can be placed on the outer surface or the inner surface of the wrapping portion 21. When the pocket 24 is placed on the outer side of the wrapping portion 21, it is convenient to replace and repair the experimental sensor; when the pocket 24 is placed on the inner side of the wrapping portion 21, it is convenient to fix the experimental sensor to avoid falling during the experiment. The specific arrangement can be made according to the experimental requirements.

[0075] As attached Figure 2 and attached Figure 3As shown, the hanging bracket 1 includes a metal rod frame 12, a receiving tray 13 and a placing portion 4. The metal rod frame 12 is composed of a plurality of metal rods. The receiving tray 13 is arranged on the metal rod frame 12 and is located inside the metal rod frame 12 to cover the opening at the bottom of the metal rod frame 12 to prevent the excrement produced by the experimental animals from falling. A buckle is provided on the outer surface of the receiving tray 13, and the buckle is engaged with the metal rod frame 12 to fix the receiving tray 13 to the metal rod frame 12. A placing portion 4 is also provided on the metal rod frame 12, and the placing portion 4 is used to place food and water to meet the basic living needs of the experimental animals.

[0076] Since the experimental animals may be suspended for several days, a placement part 4 is required to place food and water. The experimental animals are suspended by a metal chain 3 in cooperation with an I-shaped restraining garment 2. The metal chain 3 is formed by buckling a plurality of chain links, so that the experimental animals have a certain range of activities. The I-shaped restraining garment 2 is wrapped around the abdomen of the experimental animals, and has no restraining effect on the head and limbs of the experimental animals. The experimental animals can be moved to the position of the placement part 4 by shaking, and can eat food and water to ensure the normal life needs of the experimental animals, so that the experimental data of the experimental animals can also be observed;

[0077] During the hanging process, the experimental animals will consume more food and water, and thus will produce excrement. In the present application, a receiving tray 13 is arranged inside the metal rod frame 12, and the experimental animals and the placement portion 4 are both located on the top of the receiving tray 13. The excrement of the experimental animals, as well as the water and food that fall, will all fall on the receiving tray 13, which is convenient for cleaning and avoids certain impacts during the weightlessness experiment of the experimental animals.

[0078] As attached Figure 3 As shown, the metal rod frame 12 includes two U-shaped brackets 121 and a fixing plate 122. The two U-shaped brackets 121 are arranged at an angle, and the openings of the two U-shaped brackets 121 are located at the angle. The top and bottom of the open ends of the two U-shaped brackets 121 are respectively connected through a fixing plate 122, that is, a notch is formed at the angle of the metal rod frame 12, and a fixing hole 123 is provided on the fixing plate 122. The fixing plate 122 at the upper and lower ends of the notch can be connected to an external rotating device; the other ends of the two U-shaped brackets 121 are connected by a connecting rod, that is, the connecting rod is located at the bottom of the U-shaped bracket 121, and the two ends of the connecting rod are respectively fixed on one side wall of the two U-shaped brackets 121 facing each other.

[0080] In this embodiment, the U-shaped bracket 121 is formed by bending a metal round rod, and the diameter of the metal round rod is the same as the internal diameter of the buckle to facilitate the buckling of the two. At the same time, a larger or thinner metal round rod can also be selected according to data such as the weight of the experimental animal in the experiment. A fixing piece is provided on the top of the U-shaped bracket 121 to facilitate the fixing of the buckle of the metal chain 3 on the U-shaped bracket 121.

[0081] In this embodiment, the middle position of the two U-shaped brackets 121 is open. When multiple suspension devices are placed adjacent to each other to form a disk shape (such as the attached Figure 7 As shown), two adjacent placement cavities are connected. In order to prevent the experimental animals in adjacent placement cavities from being affected by each other, a partition is provided on one of the U-shaped brackets 121. The partition is detachably provided on the U-shaped bracket 121 so that the two adjacent placement cavities are isolated to prevent the experimental animals from affecting each other. At the same time, a plurality of circular holes are provided on the partition to improve the comfort of the experimental animals in the placement cavity.

[0082] As attached Figure 2 and attached Figure 6 As shown, a groove 14 is provided inside the receiving plate 13, and a baffle 15 is provided inside the groove 14. The baffle 15 divides the groove 14 into a first collecting groove and a second collecting groove, wherein the first collecting groove is located at the bottom of the experimental animal to facilitate the collection of the excrement of the experimental animal, and the second collecting groove is located at the bottom of the placement portion 4 to collect food residues or dripping water droplets, etc.; a hollow plate 16 is provided at the bottom of the first collecting groove, and the hollow plate 16 covers the top of the first collecting groove. The side wall of the hollow plate 16 overlaps the side wall of the receiving plate 13 and the baffle 15 to close the first collecting groove. A plurality of holes are opened on the hollow plate 16. The setting of the holes is used to facilitate the excrement to fall into the first collecting groove, so as to facilitate subsequent experimental analysis and research.

[0084] A drinking bottle is detachably provided on the drinking portion 41, one end of which passes through the drinking portion 41 and is located in the placement cavity. Under the action of the metal chain 3, the experimental animal can move in a small range and grab the drinking bottle through its limbs to drink water; the food portion 42 is hollowed out, and its interior can be used to place solid food. The experimental animal can eat and drink through the hollowed-out food portion 42.

[0085] In this embodiment, as shown in the attached Figure 3 As shown, the drinking portion 41 includes two first support rods 411, one end of the first support rod 411 is arranged on the metal rod frame 12, and the other end is connected to the food portion 42, so that the drinking portion 41 is located between the two U-shaped brackets 121, the two first support rods 411 are arranged one high and one low, and a plurality of bending rods 412 are arranged along the length direction of the two first support rods 411, the two ends of the bending rod 412 are respectively arranged on the two first support rods 411, and the plurality of bending rods 412 are arranged at intervals along the length direction of the first support rods 411, that is, there is a gap between two adjacent bending rods 412, so as to facilitate the fixing of the drinking bottle and pass one end of the drinking bottle through the drinking portion 41;

[0087] In this embodiment, as shown in the attached Figure 3 As shown, the food portion 42 includes two second support rods 421, a plurality of V-shaped rods 422 and two vertical plates 423. One end of the two second support rods 421 is set on the metal rod frame 12, and the other end is connected to the two first support rods 411. The two first support rods 411 correspond to the two second support rods 421 one by one, and the heights are also the same. The first support rod 411 is connected to the second support rod 421, and the two ends of the first support rod 411 and the second support rod 421 are respectively connected to the two U-shaped brackets 121, which can not only be used for The placement portion 4 can also be used to reinforce the two U-shaped brackets 121 to improve their stability; the two second support rods 421 are provided with a plurality of V-shaped rods 422 spaced apart along their length direction, and cooperate with the two second support rods 421 to form a V-shaped groove, and the V-shaped groove is used to place solid food; vertical plates 423 are also provided on both sides of the V-shaped groove, and the vertical plates 423 can prevent food from falling from both sides of the V-shaped groove; experimental animals can eat solid food through the gaps between adjacent V-shaped rods 422.
