Description

Technical Field

[0001] This utility model relates to the technical field of oral infusion in mice, and more specifically, to an oral infusion operating table for mice. Background Technology

[0002] Currently, oral infusion in mice mostly relies on manual operation by laboratory personnel. They use tools such as tweezers to open the mouth of the anesthetized mouse and then administer the infusion.

[0003] However, manually opening the mouse's mouth with tweezers or other tools to administer the infusion can easily cause soft tissue damage. Furthermore, the procedure can cause the mouse's neck to rotate, leading to infusion misalignment. In addition, prolonged handling increases the probability of operator error due to fatigue. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies where manual opening of a mouse's mouth for infusion can easily cause damage to the soft tissue of the mouse's mouth and cause deviations in the infusion position. This invention provides a mouse mouth infusion operating table that can replace manual opening of the mouse's mouth. In the process of opening the mouse's mouth, this table can not only avoid damage to the soft tissue of the mouse's mouth, but also avoid the problem of position deviations caused by the rotation of the mouse's head during infusion.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A mouse oral drip administration table is provided, comprising a base, an adjusting component fixedly mounted on the base, and a first occlusal articulator and a second occlusal articulator mounted on the base. The first occlusal articulator and the second occlusal articulator are used to hook the upper and lower incisors of a mouse, respectively. The first occlusal articulator and / or the second occlusal articulator are slidably connected to the base to allow the first occlusal articulator and the second occlusal articulator to move closer or further apart from each other. The adjusting component is connected to the first occlusal articulator and / or the second occlusal articulator to drive the first occlusal articulator and / or the second occlusal articulator to slide on the base.

[0006] In use, the mouse oral infusion operating table of this invention first uses an adjusting component to bring the first and second occlusal arches closer together until they are in contact. At this point, the experimenter gently manipulates the anesthetized mouse's upper and lower jaws to slightly open the mouse's mouth. Once the mouse's mouth is open, its upper and lower incisors are hooked onto the first and second occlusal arches, suspending the mouse on the operating table. Then, the adjusting component moves the first and second occlusal arches further apart, increasing the angle of the mouse's mouth opening until it is wide enough for oral infusion. Because the mouse is suspended on the occlusal arches by its upper and lower incisors, the medication can be precisely infused into the mouse's mouth. After the infusion is complete, the adjusting component brings the first and second occlusal arches closer together until they are in contact, and then the mouse is removed from the occlusal arches.

[0007] In use, the mouse oral dripping operating table of this utility model is suspended on the occlusal frame by the upper and lower incisors. The distance between the first and second occlusal frames can be adjusted by the distance adjustment component, thereby adjusting the opening angle of the mouse's mouth. Furthermore, the mouse suspended on the occlusal frame keeps its body in an upright position due to its own gravity, so the dripping solution can be accurately dripped into the mouse's mouth during oral dripping.

[0008] Furthermore, the first occlusal articulation device includes a first hanging rod for hooking the upper or lower incisors of the mouse, and a first and second support rods installed at both ends of the first hanging rod, the bottoms of which are connected to the base; the second occlusal articulation device includes a second hanging rod for hooking the upper or lower incisors of the mouse, and a third and fourth support rods installed at both ends of the second hanging rod, the bottoms of which are connected to the base. When the mouse is suspended on the occlusal articulation device, its upper and lower incisors are hooked onto the first and second occlusal rods, respectively.

[0009] Further, the base includes a first fixed plate and a second fixed plate arranged in parallel. The first support rod and the third support rod are slidably mounted on the first fixed plate, and the second support rod and the fourth support rod are slidably mounted on the second fixed plate. The adjusting assembly includes an active part mounted on the first fixed plate, which can drive the first support rod and the third support rod to slide on the base. The top and bottom of the first fixed plate are provided with first sliding grooves for the first support rod and the third support rod to slide. The top of the first support rod and the top of the third support rod are slidably connected to the first sliding groove at the top of the first fixed plate, and the bottom of the first support rod and the bottom of the third support rod are slidably connected to the first sliding groove at the bottom of the first fixed plate. The top and bottom of the second fixed plate are provided with second sliding grooves for the second support rod and the fourth support rod to slide. The top of the second support rod and the top of the fourth support rod are slidably connected to the second sliding groove at the top of the second fixed plate, and the bottom of the second support rod and the bottom of the fourth support rod are slidably connected to the second sliding groove at the bottom of the second fixed plate. The arrangement of the first fixed plate and the second fixed plate can further prevent the support rod from tilting or falling over during the sliding process. While both the first and second occlusal frames can slide on the base, it can also be configured such that only the first or second occlusal frame can slide on the base. In this case, the support rod of the occlusal frame that cannot slide is fixedly installed on the fixed plate.

[0010] Further, the active part includes a disc rotatably connected to the first fixed plate and a stopper mounted on the first fixed plate. The stopper prevents the disc from rotating. The disc has two guide grooves, which are symmetrically arranged about the center of the disc. The first fixed plate has a limiting groove with its axis parallel to the horizontal plane. The bottom of the first support rod and the third support rod are both provided with guide rods. The two guide rods pass through the limiting groove and extend into the two guide grooves respectively, and are slidably connected to the two guide grooves respectively. The axis of the guide groove on the disc can be a straight line that does not coincide with the radius of the disc or an arc whose center does not coincide with the center of the disc. When it is necessary to adjust the distance between the first engagement frame and the second engagement frame, the disc is rotated, and the two guide grooves on the disc rotate with the disc. Since the guide rods on the first support rod and the third support rod are slidably connected to the guide grooves through the limiting grooves, the guide rods are located at the intersection of the limiting grooves and the guide grooves. After the disc rotates, the intersections of the two guide grooves and the two limiting grooves will move closer or further apart, causing the guide rods on the first and third support rods to move closer or further apart. This movement of the guide rods on the first and third support rods in turn causes the first and third support rods to move closer or further apart, which in turn causes the first and second engagement frames to move closer or further apart. Furthermore, the driving component can also be a gear, with its upper and lower ends respectively fixedly connected to the guide rods on the first and third support rods via a rack.

[0011] Furthermore, the side wall of the disc is provided with several slots, which are arranged equidistantly in a circle around the axis of the disc. The anti-reverse component is rotatably connected to the first fixed plate and can engage with the slots. An elastic element for driving the anti-reverse component to reset is also connected to the anti-reverse component, and the other end of the elastic element is fixedly connected to the first fixed plate. When the anti-reverse component engages with the slot, it prevents the disc from continuing to rotate. The slot can be shaped like ratchet teeth, and the end of the anti-reverse component that engages with the slot is a pawl, thus preventing the disc from reversing during unidirectional adjustment. A handle is also provided at the end of the anti-reverse component away from the pawl, allowing the experimenter to rotate the anti-reverse component by turning the handle to release the pawl from the slot.

[0012] Furthermore, it also includes a connecting rod and a driven part. The driven part is mounted on the second fixed plate and can drive the second support rod and the fourth support rod to slide on the base. The two ends of the connecting rod are fixedly connected to the active part and the driven part, respectively. The driven part can move synchronously with the active part, thereby driving the second connecting rod to move synchronously with the first connecting rod, and the fourth connecting rod to move synchronously with the third connecting rod, making the sliding of the first and second engagement frames more stable. The structure of the driven part and the way in which the driven part drives the second and fourth connecting rods are the same as the structure of the active part and the way in which the active part drives the first and third connecting rods. That is, the driven part is also a disc with two guide grooves. The second fixed plate, like the first fixed plate, also has a limiting groove. The bottom of the second and fourth support rods also has guide rods. The guide rods at the bottom of the second and fourth support rods also pass through the limiting grooves on the second fixed plate and extend into the two guide grooves on the driven part, respectively, and are slidably connected to the two guide grooves.

[0013] Furthermore, the diameters of the first and second hanging rods are 1mm-1.5mm. When the diameters of the first and second hanging rods are between 1mm and 1.5mm, it is easier to hook the upper and lower incisors of the mouse onto the first and second hanging rods.

[0014] Furthermore, the first hanging rod is also provided with a first elastic piece for pressing the upper or lower jaw of the mouse. Each end of the first elastic piece has a first tensioning block that can be fixed to the first hanging rod, and the first tensioning block is slidably connected to the first hanging rod. The second hanging rod is also provided with a second elastic piece for pressing the upper or lower jaw of the mouse. Each end of the second elastic piece has a second tensioning block that can be fixed to the second hanging rod, and the second tensioning block is slidably connected to the second hanging rod. The elastic piece is a deformable metal sheet under force, and a soft silicone pad is provided on the part of the elastic piece that abuts against the mouse. The hanging rod passes through the tensioning block, and a tightening bolt is threaded onto the tensioning block. After the tightening bolt extends into the tensioning block, it abuts against the hanging rod. When the tightening bolt abuts against and presses against the hanging rod, the tightening bolt fixes the tensioning block to the hanging rod. The first and second elastic pieces can abut against the upper and lower jaws of the mouse respectively, further preventing the mouse from falling off the bite block.

[0015] Furthermore, a first buffer sleeve is fixedly fitted onto the first hanging rod, and the first buffer sleeve is located between the two first tensioning blocks; a second buffer sleeve is fixedly fitted onto the second hanging rod, and the second buffer sleeve is located between the two second tensioning blocks. The buffer sleeves on the hanging rods can further protect the mouse's oral cavity, and the buffer sleeves can be soft silicone sleeves or soft rubber sleeves.

[0016] Furthermore, a first height adjusting rod and a second height adjusting rod are respectively fixedly installed at both ends of the first hanging rod. The first height adjusting rod is slidably connected to the top of the first support rod and can be fixed to the first support rod, and the second height adjusting rod is slidably connected to the top of the second support rod and can be fixed to the second support rod. A third height adjusting rod and a fourth height adjusting rod are respectively fixedly installed at both ends of the second hanging rod. The third height adjusting rod is slidably connected to the top of the third support rod and can be fixed to the third support rod, and the fourth height adjusting rod is slidably connected to the top of the fourth support rod and can be fixed to the fourth support rod. The height adjusting rods allow the height of the bite frame to be adjusted, accommodating mice of more sizes. The hanging rod is provided with a socket for inserting the height adjusting rod, and a locking bolt is threaded onto the side wall of the socket to abut against the height adjusting rod. The locking bolt can compress the height adjusting rod to fix it inside the hanging rod.

[0017] Compared with the prior art, the beneficial effects of this utility model are: In use, the mouse oral dripping operating table of this utility model is suspended on the occlusal frame by the upper and lower incisors. The distance between the first and second occlusal frames can be adjusted by the distance adjustment component, thereby adjusting the opening angle of the mouse's mouth. Furthermore, the mouse suspended on the occlusal frame keeps its body in an upright position due to its own gravity, so the dripping solution can be accurately dripped into the mouse's mouth during oral dripping.

[0022] Example 1 This embodiment is a first embodiment of a mouse oral drip administration station, as follows: Figure 1 As shown, the device includes a base 1, an adjusting assembly 2 fixedly mounted on the base 1, and a first occlusal frame 3 and a second occlusal frame 4 mounted on the base 1. The first occlusal frame 3 and the second occlusal frame 4 are used to hook the upper and lower incisors of the mouse, respectively. The first occlusal frame 3 and / or the second occlusal frame 4 are slidably connected to the base 1 to allow the first occlusal frame 3 and the second occlusal frame 4 to move closer or further apart from each other. The adjusting assembly 2 is connected to the first occlusal frame 3 and / or the second occlusal frame 4 to drive the first occlusal frame 3 and / or the second occlusal frame 4 to slide on the base 1.

[0023] Specifically, such as Figure 2 and Figure 4 As shown, the first occlusal frame 3 includes a first hook 301 for attaching to the upper or lower incisors of a mouse, and a first support 302 and a second support 303 installed at both ends of the first hook 301. The bottoms of the first support 302 and the second support 303 are both connected to the base 1. The second occlusal frame 4 includes a second hook 401 for attaching to the upper or lower incisors of a mouse, and a third support 402 and a fourth support 403 installed at both ends of the second hook 401. The bottoms of the third support 402 and the fourth support 403 are both connected to the base 1.

[0024] The working principle or process of this embodiment is as follows: In this embodiment, the mouse oral infusion operating table is used by first adjusting the distance component 2 to bring the first occlusal frame 3 and the second occlusal frame 4 closer together until they are in contact. At this time, the experimenter gently moves the upper and lower jaws of the anesthetized mouse to slightly open the mouse's mouth. The mouse's upper and lower incisors are then hooked onto the first hook 301 of the first occlusal frame 3 and the second hook 401 of the second occlusal frame 4. The mouse can then be suspended on the operating table using its upper and lower incisors. Then, the distance component 2 is used to move the first occlusal frame 3 and the second occlusal frame 4 further apart, increasing the angle at which the mouse's mouth opens until it is wide enough for oral infusion. Since the mouse is suspended on the occlusal frame using its upper and lower incisors, the medication can be accurately dripped into the mouse's mouth. After the infusion is completed, the distance component 2 is used to bring the first occlusal frame 3 and the second occlusal frame 4 closer together until they are in contact, and then the mouse is removed from the occlusal frame.

[0025] The beneficial effects of this embodiment are as follows: In this embodiment, the mouse oral dripping operating table is used by suspending the mouse on the occlusal frame with its upper and lower incisors. The distance between the first occlusal frame 3 and the second occlusal frame 4 can be adjusted by adjusting the distance component 2, thereby adjusting the opening angle of the mouse's mouth. Furthermore, the mouse suspended on the occlusal frame keeps its body in an upright position due to its own gravity, so the dripping solution can be accurately dripped into the mouse's mouth during oral dripping.

[0026] Example 2 This embodiment is a second embodiment of a mouse oral drip administration station. This embodiment is based on the first embodiment, as follows: Figures 1-5 As shown, both the first occlusal frame 3 and the second occlusal frame 4 can slide on the base 1.

[0027] Specifically, the base 1 includes a first fixed plate 101 and a second fixed plate 102 arranged in parallel. The first support rod 302 and the third support rod 402 are slidably mounted on the first fixed plate 101, and the second support rod 303 and the fourth support rod 403 are slidably mounted on the second fixed plate 102. The top and bottom of the first fixed plate 101 are provided with first sliding grooves 111 for the first support rod 302 and the third support rod 402 to slide; the top and bottom of the second fixed plate 102 are provided with second sliding grooves 121 for the second support rod 303 and the fourth support rod 403 to slide.

[0028] Specifically, the adjusting assembly 2 includes an active part 5 mounted on the first fixed plate 101. The active part 5 can drive the first support rod 302 and the third support rod 402 to slide on the base 1. The active part 5 includes a disc 501 rotatably connected to the first fixed plate 101 and a stop member 502 mounted on the first fixed plate 101. The stop member 502 can prevent the disc 501 from rotating. The disc 501 is provided with two guide grooves 511, which are symmetrically arranged about the center of the disc 501. The first fixed plate 101 is provided with a limiting groove 112 parallel to the horizontal plane of the axis. The bottom of the first support rod 302 and the third support rod 402 are provided with guide rods 6. The two guide rods 6 pass through the limiting groove 112 and extend into the two guide grooves 511 respectively and are slidably connected to the two guide grooves 511 respectively.

[0029] Specifically, the axis of the guide groove 511 on the disk 501 is either a straight line that does not coincide with the radius of the disk 501 or an arc whose center does not coincide with the center of the disk 501.

[0030] Specifically, the side wall of the disc 501 is provided with a number of slots 512, which are arranged equidistantly in a circle around the axis of the disc 501. The anti-reverse member 502 is rotatably connected to the first fixing plate 101 and can engage with the slots 512. The anti-reverse member 502 is also connected to an elastic member 503 for driving the anti-reverse member 502 to reset. The other end of the elastic member 503 is fixedly connected to the first fixing plate 101.

[0031] Specifically, the slot 512 can be shaped like a ratchet tooth, and the end of the anti-reverse component 502 that engages with the slot 512 is a pawl 521, while the other end is provided with a handle 522.

[0032] Specifically, it also includes a connecting rod 7 and a driven part 8 that moves synchronously with the driving part 5. The driven part 8 is mounted on the second fixed plate 102 and can drive the second support rod 303 and the fourth support rod 403 to slide on the base 1. The two ends of the connecting rod 7 are fixedly connected to the driving part 5 and the driven part 8, respectively. The structure of the driven part 8 and the way in which the driven part 8 drives the second and fourth connecting rods 7 to move are the same as the structure of the driving part 5 and the way in which the driving part 5 drives the first and third connecting rods 7 to move.

[0033] The working principle or process of this embodiment is as follows: When it is necessary to adjust the distance between the first bite frame 3 and the second bite frame 4, the disc 501 is rotated. As the disc 501 rotates, the two guide grooves 511 on it follow its rotation. Since the guide rods 6 on the first support rod 302 and the third support rod 402 are slidably connected to the guide grooves 511 through the limiting groove 112, the guide rods 6 are located at the intersection of the limiting groove 112 and the guide groove 511. After rotating the disc 501, the intersection of the two guide grooves 511 and the two limiting grooves 112 will move closer or further apart, causing the guide rods 6 on the first support rod 302 and the third support rod 402 to move closer or further apart. This movement of the guide rods 6 on the first support rod 302 and the third support rod 402 will cause the first support rod 302 and the third support rod 402 to move closer or further apart, which in turn will cause the first bite frame 3 and the second bite frame 4 to move closer or further apart. The rotation of the disk 501 of the driving part 5 drives the driven part 8 to move synchronously via the connecting rod 7. The movement of the driven part 8 drives the second support rod 303 to move synchronously with the first support rod 302, and the fourth support rod 403 to move synchronously with the third support rod 402. When the pawl 521 engages with the slot 512, it prevents the disk 501 of the driving part 5 from continuing to rotate.

[0034] The beneficial effects of this embodiment are as follows: The ratchet 521 on the anti-reverse component 502 prevents the disc 501 from reversing during unidirectional adjustment, and the handle 522 makes it easier for the experimenter to operate. The driven part 8 can drive the second link 7 to move synchronously with the first link 7, and the fourth link 7 to move synchronously with the third link 7, thereby making the sliding of the first engagement frame 3 and the second engagement frame 4 more stable.

[0035] Example 3 This embodiment is a third embodiment of a mouse oral drip operating table. The difference between this embodiment and embodiment two is that the first occlusal frame 3 can slide on the base 1, and the second occlusal frame 4 is fixed on the base 1.

[0036] Specifically, the first support rod 302 is slidably mounted on the first fixed plate 101; the second support rod 303 is slidably mounted on the second fixed plate 102; the third support rod 402 is fixedly mounted on the first fixed plate 101; and the fourth support rod 403 is fixedly mounted on the second fixed plate 102. The top and bottom of the first fixed plate 101 are provided with sliding grooves for the first support rod 302 to slide; the top and bottom of the second fixed plate 102 are provided with sliding grooves for the second support rod 303 to slide.

[0037] Specifically, the active part 5 can drive the first support rod 302 to slide on the base 1. The active part 5 includes a disc 501 rotatably connected to the first fixed plate 101 and a stop member 502 installed on the first fixed plate 101. The stop member 502 can prevent the disc 501 from rotating. The disc 501 is provided with a guide groove 511. The first fixed plate 101 is provided with a limiting groove 112 parallel to the horizontal plane. The bottom of the first support rod 302 is provided with a guide rod 6. The guide rod 6 passes through the limiting groove 112 and extends into the guide groove 511 and is slidably connected to the guide groove 511.

[0038] The working principle or process of this embodiment is as follows: When it is necessary to adjust the distance between the first bite frame 3 and the second bite frame 4, the disc 501 is rotated. As the disc 501 rotates, the guide groove 511 on the disc 501 rotates with it. Since the guide rod 6 on the first support rod 302 is slidably connected to the guide groove 511 through the limiting groove 112, the guide rod 6 is located at the intersection of the limiting groove 112 and the guide groove 511. After rotating the disc 501, the intersection of the guide groove 511 and the limiting groove 112 will move closer to or further away from the second bite frame 4, causing the guide rod 6 on the first support rod 302 to move closer to or further away from the second bite frame 4. This movement of the guide rod 6 on the first support rod 302 towards or away from the second bite frame 4 causes the first support rod 302 to move closer to or further away from the second bite frame 4, which in turn causes the first bite frame 3 to move closer to or further away from the second bite frame 4.

[0039] Other features, working principles, and beneficial effects of this implementation are consistent with those of Example 2.

[0040] Example 4 This embodiment is the third embodiment of a mouse oral drip administration station. This embodiment is based on embodiments one to three, such as... Figure 2 and Figure 4 As shown, the other structures of the control panel are further defined.

[0041] Specifically, the first hanging rod 301 is also provided with a first elastic piece 11 for pressing the upper or lower jaw of the mouse. Both ends of the first elastic piece 11 are provided with first tension blocks 12 that can be fixed to the first hanging rod 301, and the first tension blocks 12 are slidably connected to the first hanging rod 301. The second hanging rod 401 is also provided with a second elastic piece 13 for pressing the upper or lower jaw of the mouse. Both ends of the second elastic piece 13 are provided with second tension blocks 14 that can be fixed to the second hanging rod 401, and the second tension blocks 14 are slidably connected to the second hanging rod 401. The elastic piece is a deformable metal sheet under force, and a soft silicone pad is provided on the part of the elastic piece that abuts against the mouse. The hanging rod passes through the tension block, and a tightening bolt is threaded onto the tension block. After the tightening bolt extends into the tension block, it abuts against the hanging rod. When the tightening bolt abuts against and presses against the hanging rod, the tightening bolt fixes the tension block to the hanging rod.

[0042] Specifically, the diameters of the first hanging rod 301 and the second hanging rod 401 are 1mm-1.5mm. A first buffer sleeve 9 is fixedly sleeved on the first hanging rod 301, and the first buffer sleeve 9 is located between the two first tension blocks 12; a second buffer sleeve 10 is fixedly sleeved on the second hanging rod 401, and the second buffer sleeve 10 is located between the two second tension blocks 14.

[0043] Specifically, a first height adjusting rod 16 and a second height adjusting rod 15 are fixedly installed at both ends of the first hanging rod 301. The first height adjusting rod 16 is slidably connected to the top of the first support rod 302 and can be fixed to the first support rod 302. The second height adjusting rod 15 is slidably connected to the top of the second support rod 303 and can be fixed to the second support rod 303. A third height adjusting rod 18 and a fourth height adjusting rod 17 are fixedly installed at both ends of the second hanging rod 401. The third height adjusting rod 18 is slidably connected to the top of the third support rod 402 and can be fixed to the third support rod 402. The fourth height adjusting rod 17 is slidably connected to the top of the fourth support rod 403 and can be fixed to the fourth support rod 403. The hanging rod is provided with a socket for inserting the height adjusting rod. A locking bolt that abuts against the height adjusting rod is threaded on the side wall of the socket. The locking bolt can compress the height adjusting rod to fix the height adjusting rod inside the hanging rod.

[0044] The beneficial effects of this embodiment are as follows: When the diameters of the first hook 301 and the second hook 401 are between 1mm and 1.5mm, it is easier to hook the upper and lower incisors of the mouse onto the first hook 301 and the second hook 401. The first elastic plate 11 and the second elastic plate 13 can respectively abut against the upper and lower jaws of the mouse, further preventing the mouse from falling off the occlusal frame. The soft silicone sleeves on the hooks further protect the mouse's oral cavity. The height adjustment rod makes the height of the occlusal frame adjustable, accommodating mice of more sizes.
