[0001] This invention relates to the field of gastrointestinal motility testing, and more specifically, to a veterinary intestinal motility testing device with a fixation function. [Background Technology]

[0002] Animals are excellent experimental models for simulating human behavior and physiological functions. In basic research on digestive system diseases, intestinal motility testing is an important method for assessing the digestive system. During experiments, because animal activity is difficult to control subjectively, some animal experiments even require multiple personnel to operate together, especially with smaller rodents such as rats and mice. Current methods for detecting intestinal motility in rodents typically involve manually injecting steel balls into the intestines of mice and recording the time it takes for the mouse to expel the balls. However, existing injection devices are very inconvenient to use. The rat's tail movements during injection interfere with the device's normal operation, and existing devices are prone to damaging the animal's intestinal mucosa. The steel balls are also difficult to inject into the rat's intestines, and operators may be bitten by the animal. Therefore, there is an urgent need to design an intestinal motility testing device that can immobilize the animal and facilitate the injection of steel balls. [Summary of the Invention]

DETAILED DESCRIPTION

[0028] The specific embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0029] The specific embodiments of the present application are described in detail below with reference to the accompanying drawings. Figures 1 to 6 The specific embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0030] The present application describes a kind of intestinal tract dynamic detection device with fixing function for veterinary, for being used when carrying out intestinal motility detection to mouse, steel ball is injected into mouse intestinal tract, and the intestinal motility health condition of mouse is judged according to the discharge time of steel ball.

[0031] As shown in Figure 1 、 3 The present application is a kind of intestinal tract dynamic detection device with fixing function for veterinary, including bottom plate 1, the bottom plate 1 is provided with tail part limiting mechanism 2, the tail part limiting mechanism 2 is connected with injection mechanism 3;

[0032] The tail part limiting mechanism 2 includes the clamping member 22 for clamping animal tail, overturning member 21 for clamping member 22 setting and driving clamping member 22 displacement;

[0033] The injection mechanism 3 comprises a sliding piece 31 which is in sliding connection with the bottom plate 1, and an injection piece 32 which is arranged on the sliding piece 31;

[0034] The turnover member 21 is connected with the sliding piece 31 and drives the sliding piece 31 to slide on the bottom plate 1, thereby adjusting the position of the injection piece 32;

[0035] The injection piece 32 comprises a sleeve 321 which contains medical lubricant, and an insertion part 322 which is arranged at one end of the sleeve 321 close to the tail limiting mechanism 2, wherein the insertion part 322 is made of silica gel material, and a steel ball containing part 323 which is detachably connected in the sleeve 321, wherein the steel ball containing part 323 is arranged with a steel ball, and one end of the steel ball containing part 323 is in communication with the insertion part 322, and the other end of the steel ball containing part 323 is in communication with the sleeve 321, and a pushing part 324 which is in sliding connection in the sleeve 321, wherein when the device is not used, the pushing part 324 is located at the communicating end of the steel ball containing part 323 and the insertion part 322, and the pushing part 324 extends out of the sleeve 321 from the other end of the sleeve 321, and when the pushing part 324 slides to push the medical lubricant, the medical lubricant is output along the channel of the sleeve 321, the steel ball containing part 323 and the insertion part 322, and at the same time, the steel ball in the steel ball containing part 323 is also output along the channel.

[0036] Through the arrangement of the tail limiting mechanism 2, the tail of the mouse is first clamped by the clamping member 22 before the steel ball is injected, and then the tail is turned up by the turnover member 21, so that the anus of the mouse is exposed, and then the sliding piece 31 is driven to move close to the mouse during the turning process of the turnover member 21, the sliding piece 31 drives the injection piece 32 to insert into the anus of the mouse, and when the insertion part 322 is inserted for a certain distance, the steel ball needs to be injected, the movement of the turnover member 21 is stopped, then the pushing part 324 is pulled to push the medical lubricant in the sleeve 321 into the steel ball containing part 323, so that the steel ball is more easily pushed into the intestine of the mouse through the insertion part 322, and the insertion part 322 is made of silica gel material, which reduces the damage to the intestinal mucosa of the mouse.

[0037] Further, as Figure 1As shown, the flipping mechanism 21 includes two mounting blocks 211 symmetrically fixedly connected to the base plate 1. Each mounting block 211 has a rotating shaft 212 rotatably connected to it. The two rotating shafts 212 are coaxial and pass through the corresponding mounting block 211. One end of one rotating shaft 212 away from the other mounting block 211 is fixedly connected to the output end of a motor 213. The motor 213 is fixedly connected to the base plate 1. Adjacent ends of the two rotating shafts 212 are respectively fixedly connected to flipping rods 214. One end of each flipping rod 214 away from the rotating shaft 212 is fixedly connected to the clamping member 22. With the flipping rods 214, after the clamping member 22 clamps the mouse's tail, the rotation of the output end of the motor 213 causes the rotating shaft 212 to drive the flipping rods 214 to flip. The flipping rods 214 drive the tail to flip through the clamping member 22, facilitating the exposure of the anus.

[0038] Furthermore, such as Figure 1 As shown, the clamping member 22 includes a fixed rod 221 fixedly connected between the two flipping rods 213. The fixed rod 221 has an electromagnetic groove 222 communicating with the external space. When the flipping rod 213 is parallel to the base plate 1, the opening of the electromagnetic groove 222 faces away from the base plate 1. Two electromagnetic sliders 223 are slidably connected in the electromagnetic groove 222. When the device is not in use, the two electromagnetic sliders 223 are located at the two ends of the electromagnetic groove 222 respectively. When the mouse is fixed on the base plate, the mouse is located on the side of the fixed rod 221 away from the injection mechanism 2. When the mouse's tail is on the fixed rod 221, the electromagnetic sliders 223 are activated, causing the two electromagnetic sliders 223 to move towards the center of the fixed rod 221, clamping the mouse's tail. Then, in conjunction with the flipping of the flipping mechanism 21, the mouse's anus is exposed, while preventing the tail from obstructing the injection process.

[0039] It should be noted that the electromagnetic groove 222 and the electromagnetic slider 223 are existing technologies and will not be described in detail here.

[0040] Furthermore, such as Figure 1As shown, the elastic reset member includes two symmetrically formed T-shaped grooves 311 in the base plate 1. The length direction of the T-shaped grooves 311 is perpendicular to the axis of the fixed rod 221, ensuring that the sliding member 31 can slide towards the mouse. A T-shaped sliding block 312 is slidably connected in each T-shaped groove 311. A first spring 313 is connected between each T-shaped sliding block 312 and the side wall of the corresponding T-shaped groove 311 away from the tail restraint mechanism 2. A sliding member 31 is fixedly connected between the two T-shaped sliding blocks 312. The sliding member 31 includes a fixed... A cylinder 314 is connected to each of the T-shaped sliding blocks 312, the axis of the cylinder 314 is perpendicular to the base plate 1, a fixing plate 315 is fixedly connected between two cylinders 314, and a pull rope 4 is connected between each cylinder 314 and the fixing rod 221. The injection component 32 is disposed on the fixing plate 315. When the fixing rod 221 moves, the cylinder 314 is moved by the pull rope 4, the cylinder 314 moves the fixing plate 315 towards the mouse, and the fixing plate 315 moves the injection component 32 towards the mouse.

[0041] It should be noted that the pull rope 4 is made of a flexible material.

[0042] like Figure 5 As shown, the end of the insertion part 322 away from the sleeve 321 is rounded.

[0043] Furthermore, such as Figure 6 As shown, the insertion part 322 is a hollow cylindrical shape. The rounded corners make it easier to insert into the anus of a mouse and prevent it from scratching the mucosa when moving in the mouse's intestines.

[0044] Furthermore, such as Figure 6 As shown, the sleeve 321 is cylindrical and is fixedly connected to the center of the fixing plate 315. The axis of the sleeve 321 is perpendicular to the fixing plate 315. The sleeve 321 has a cylindrical space inside and two circular holes are opened at both ends. The two circular holes are coaxial. The circular hole near the tail limiting mechanism 2 communicates with the insertion part 322, and the circular hole away from the tail limiting mechanism 2 is used to disassemble the steel ball receiving part 323 to facilitate the addition of steel balls and lubricant.

[0045] Furthermore, such as Figure 6As shown, the steel ball receiving part 323 includes a cylinder 3231 with one open end. The cylinder 3231 is inserted into the sleeve 321 through a circular hole away from the tail limiting mechanism 2. The open end of the cylinder 3231 communicates with the insertion part 322. A stop block 3234 is fixedly connected to the closed end of the cylinder 3231. The stop block 3234 abuts against the end of the sleeve 321. The stop block 3234 is made of magnetic material. The end of the sleeve 321 away from the tail limiting mechanism 2 is also made of magnetic material. The stop block 3234 and the end of the sleeve 321 are magnetically attracted. Several through holes 3232 are opened in the cylinder 3231. The through holes 3232 communicate with the sleeve 321. The through holes 3232 are close to the cylinder 3231. At the closed end of 31, a ring 3233 is provided on the side of the through hole 3232 near the open end of the cylinder 3231. The ring 3233 is fixedly connected to the inner wall of the cylinder 3231. The steel ball is located on the side of the ring 3233 away from the through hole 3232, and the diameter of the steel ball is larger than the inner diameter of the ring. When the medical lubricant enters the cylinder 3231 through the through hole 3232, the lubricant first fills the part between the ring 3233 and the closed end of the cylinder 3231, so that the lubricant has sufficient pushing force on the steel ball, avoiding the steel ball remaining inside the cylinder 3231, which would affect the experimental results. At the same time, the lubricant also lubricates the steel ball during the pushing process, making it easier for it to pass through the insertion part 322 made of silicone material.

[0046] Furthermore, such as Figure 5 , 6As shown, the pushing part 324 includes a sliding disc 3241 that is slidably and sealingly connected to the sleeve 321. The sliding disc 3241 is slidably and sealingly fitted onto the cylinder 3231. A second spring 3242 is connected between the sliding disc 3241 and the end of the sleeve 321 away from the tail limiting mechanism 2. The second spring 3242 is fitted onto the cylinder 3231. Two connecting rods 3243 are symmetrically and fixedly connected to the sliding disc 3241. Each connecting rod 3243 extends out of the sleeve 321 in a direction away from the mouse. The connecting rod 3243 is slidably and sealingly connected to the sleeve 321. A pull plate 3244 is fixedly connected to the extended ends of the two connecting rods 3243. Each 3244 has an opening for removal. The stop 3234 can pass through the extraction hole 3245. When it is necessary to inject steel balls into the intestine, the pull plate 3244 is pulled away from the mouse. The pull plate 3244 drives the sliding disk 3241 to move through the connecting rod 3243. The sliding disk 3241 squeezes lubricant into the cylinder 3231 and compresses the second spring 3242 at the same time. After the extrusion is completed, the pull plate 3244 is released, and the sliding disk 3241 returns to its original position under the action of the second spring 3242. When it is necessary to add steel balls to the cylinder 3231, the stop 3234 is pulled to separate the stop 3234 from the sleeve 321 and the cylinder 3231 is taken out from the extraction hole 3245.

[0047] Furthermore, the outer surface of the insertion part 322 is provided with scale lines along the axial direction, and the 0 scale line is located at the end of the insertion part 322 away from the sleeve 321; in use, the depth of the insertion part 322 into the intestine is determined according to the scale lines, thereby determining whether to inject steel balls.

[0048] Furthermore, such as Figure 1 , 4As shown, a fixing mechanism 5 is provided on the base plate 1. The fixing mechanism 5 includes two symmetrically arranged leg fixing mechanisms 51. The symmetrical planes of the two leg fixing mechanisms 51 coincide with the symmetrical planes of the two T-shaped grooves 311, which facilitates the insertion of the injection component 32 into the mouse's anus. Each leg fixing mechanism 51 includes a U-shaped component 511 slidably connected to the base plate 1. The U-shaped component is located between the two mounting blocks 211. The two straight sections of the U-shaped component 511 penetrate the base plate 1. A connecting plate 512 is fixedly connected between the extended ends of the two straight sections of the U-shaped component 511. An electric push rod 513 is fixedly connected between the connecting plate 512 and the base plate 1. When it is necessary to fix the mouse, the mouse's leg is placed between the two straight sections of the U-shaped component. The electric push rod 513 is activated, and the electric push rod 513 extends, thereby driving the U-shaped component to move closer to the mouse's leg through the connecting plate 512, thereby fixing the mouse's leg. During the injection process, the mouse moves around randomly.

[0049] Furthermore, such as Figure 2 , 3 As shown, the fixing mechanism 5 also includes a head fixing mechanism 52. The head fixing mechanism 52 includes two lifting members symmetrically arranged on the base plate 1, and a limiting member fixedly connected between the lifting members to restrict the head. Each lifting member includes a mounting rod 521, and the two mounting rods 521 are respectively provided with lifting slots 522 with opposite openings. A lifting block 523 is slidably connected in each lifting slot 522. A third spring 524 is connected between each lifting block 523 and the side wall of the lifting slot 522 near the base plate 1. A magnetic switch 525 is fixedly installed at the same position of the two lifting slots 522. The magnetic switch 523 is electrically connected to the motor 213. When the lifting block 523 is in contact with the head, a magnetic switch 525 is installed in the same position of the two lifting slots 522. When the magnetic switch 525 abuts, the magnetic switch 525 and the lifting block 523 are magnetically attracted, and a start signal is sent to the motor 213. The limiting member includes a semi-circular ring 526 fixedly connected between the two lifting blocks 523, and the center of the semi-circular ring 526 is on the symmetrical plane of the two leg fixing mechanisms 51. After the mouse's legs are fixed, the semi-circular ring 526 is pushed to move closer to the base plate 1. When the lifting block 523 abuts the magnetic switch 525, the pushing of the semi-circular ring 526 stops, and the mouse's head is fixed. Before this, the mouse's legs have been fixed. At this time, the magnetic switch 525 sends a start signal to the motor 213 to carry out the next injection operation.

[0050] Furthermore, a protective sleeve made of rubber material is fixedly fitted onto the restrictor to prevent injury to the mouse when the restrictor restricts the mouse's head.

[0051] Furthermore, such asFigure 4 As shown, four matrix-arranged support legs 6 are fixedly connected to the back of the base plate 1, which support the entire device.

[0052] It should be noted that the back side of the base plate 1 is the side opposite to the mounting surface of the tail limiting mechanism 2.

[0053] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements and additions without departing from the method of the present invention, and these improvements and additions should also be considered within the scope of protection of the present invention.
