Abstract
Description
Technical Field
[0001] This utility model relates to the field of experimental equipment technology, and in particular to an experimental animal grasping device. Background Technology
[0002] In pharmacological experiments, the selection of animal models and the design of experimental procedures are crucial for ensuring the effectiveness and safety of drug development. Existing equipment relies on close-range manual operation, and operators are at high risk of being scratched by animals (12%-15%). Rodent teeth and claws can easily tear through conventional glove materials, potentially leading to bacterial infections or viral transmission.
[0003] Traditional methods require capturing the mouse using a mouse catcher before transferring it to a separate, secured device. This process carries the risk of the sample falling off due to struggling. Furthermore, the simultaneous movement of the catching device and the securing device during placement can easily injure the small animal, hindering accurate data collection. Utility Model Content

[0017] Furthermore, rotating arms are connected to both sides of the rotating shaft, and a protruding post is pivotally connected to the side of the rotating arm facing the outside of the box body;
[0018] The box body is provided with sliding grooves on both sides corresponding to the rotating arm, and the protrusion is provided in the sliding groove;

[0020] Furthermore, the bottom wall of the box body is also provided with a through lower outlet, which is connected to the side outlet;
[0021] The chute includes a first horizontal section arranged laterally, a vertical section disposed with the first horizontal section, and a second horizontal section connected to the other side of the vertical section;
[0022] The vertical section is provided along the height direction of the box body;
[0023] The second horizontal section extends to one end of the side outlet. When the second driving part drives the rotating shaft to slide to the vertical section, the second clamping plate rotates 90°. When the rotating shaft slides to the second horizontal section, the second clamping plate is located at the lower outlet, and the second clamping plate rotates 180°.
[0024] Furthermore, the storage assembly includes a cylinder connected to the box body, support columns spaced apart inside the cylinder body, and a plurality of rubber sleeves fitted onto the outside of the support columns.
[0025] The cylindrical body is arranged along the length of the box body, and the opening faces the guide tube;
[0026] The cylinder is also provided with an elastic element, which is located between the inner wall of the box and the rubber sleeve.
[0027] Furthermore, the top cover is provided with a curved groove, and a sliding slider is provided in the groove, with each slider corresponding to a rubber sleeve;
[0028] The connector is located between the rubber sleeve and the slider; the opening of the groove is located on the same side as the side outlet, and when the second clamping plate moves away from the side outlet, the connector and the slider disengage from the groove.

The gripper assembly includes a plurality of grippers that are driven to open and close relative to each other.
[0030] When the gripper assembly is in the retracted state, the gripper extends between the rubber sleeve and the support column; the fifth drive unit drives the gripper assembly downward to one side of the guide tube, and the fourth drive unit drives the fifth drive unit to rotate 180°;
[0031] When the grippers are in an extended state, the gripper covers the head of the experimental sample and gradually retracts, and the rubber sleeve slides down to the neck of the experimental sample.
[0032] Furthermore, the gripper assembly also includes a four-jaw cylinder, with the grippers respectively connected to the movable ends of the four-jaw cylinder;
[0033] The front end of the gripper is provided with a baffle, and several baffles form a circular retaining ring to prevent the rubber sleeve from sliding backward.
[0034] The jaws have a tapered section at the end, which gradually decreases in size towards the end.
[0035] Compared with the prior art, this utility model has the following advantages:
[0036] The experimental animal grasping device of this invention uses a guide tube to directly align the container holding the experimental sample with the guide tube. As the experimental sample moves to the end of the guide tube, a sensor sends a signal, and the first clamping component clamps and fixes the head of the experimental sample to prevent it from retracting. Simultaneously, the sleeve component removes the rubber sleeve and moves to the head of the experimental sample, placing the rubber sleeve over the head. The connecting component then constrains the head of the experimental sample to the end of the guide tube. At this point, the first clamping component releases, and the second clamping component moves to the guide tube. The first linear module drives the sleeve component to move away from the guide tube, and the second clamping component clamps and fixes the body of the experimental sample, thus achieving omnidirectional fixation of the experimental sample.
[0037] In addition, the grasping device uses a first clamping component, a sleeve component, and a second clamping component to clamp the experimental sample, fixing the body and head of the experimental sample to prevent the animal from struggling and falling out of the device. By setting up a rubber sleeve and a connector, the experimental sample can be placed on the external fixing device by manually pulling the connector and the second clamping component, which not only prevents the animal from falling out, but also eliminates the need for close-range operation, thus improving the safety of the operator.

[0060] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0061] This embodiment relates to a laboratory animal grasping device, which, as a whole, is as follows: Figures 1 to 3 As shown, the gripping device includes a housing with an inner cavity, a guide tube 1 disposed in the inner cavity, a first clamping assembly 2 disposed at the tail end of the guide tube 1, a second clamping assembly 3 slidably connected to the bottom of the housing, and a first driving part 4 for driving the second clamping assembly 3 to slide. The first clamping assembly 2 is used to clamp the head of the experimental sample, and a sensor for monitoring the experimental sample is provided at the tail end of the guide tube 1.
[0062] The box also includes a storage assembly 5, within which a rubber sleeve 6 is installed. A connecting assembly 7, which moves the rubber sleeve 6 to the head of the experimental sample, is also located inside the box. An elastic connector 8, connected to the rubber sleeve 6, is located on the top of the box. A first linear module 9 is located on the top of the box, which drives the connecting assembly 7 to slide along the length of the box. A second clamping assembly 3 is used to clamp the body of the experimental sample.
[0063] In this embodiment, the experimental animal grasping device uses a guide tube 1 to directly align the container holding the experimental sample with the guide tube 1. As the experimental sample moves to the tail of the guide tube 1, a sensor sends a signal, and the first clamping component 2 clamps and fixes the head of the experimental sample to prevent it from retracting. Simultaneously, the sleeve component 7 removes the rubber sleeve 6 and moves it to the head of the experimental sample, placing the rubber sleeve 6 on the head. The connecting piece 8 then constrains the head of the experimental sample to the end of the guide tube 1. At this point, the first clamping component 2 releases, and the second clamping component 3 moves to the guide tube 1. The first linear module 9 drives the sleeve component 7 to move away from the guide tube 1, and the second clamping component 3 clamps and fixes the body of the experimental sample, thus achieving omnidirectional fixation of the experimental sample.
[0064] In addition, the grasping device uses a first clamping component 2, a sleeve component 7, and a second clamping component 3 to clamp the experimental sample, fixing the body and head of the experimental sample to prevent the animal from struggling and falling out of the device. By setting up a rubber sleeve 6 and a connector 8, the experimental sample can be placed on the external fixing device by manually pulling the connector 8 and the second clamping component 3, which not only prevents the animal from falling out, but also eliminates the need for close-range operation, improving the safety of the operator.
[0065] Based on the above overall description, an exemplary structure of the experimental animal grasping device in this embodiment is as follows: Figures 1 to 3 As shown, the first drive unit 4 includes a motor connected to the outside of the housing, a lead screw connected to the motor, the lead screw passing through the housing and threadedly connected to the sliding plate 301 described below. The motor rotates forward and backward to drive the sliding plate 301 to move back and forth, thereby adjusting the position of the second clamping assembly 3 to facilitate the gripping of the experimental sample. Specifically, the second clamping assembly 3 clamps the experimental sample below the abdomen, and its clamping range can be changed by adjusting the clamping plate described below.
[0066] like Figures 1 to 4 As shown, the box includes a box body 10 with an opening at the top and a top cover 11 that is fastened to the top of the box body 10. Along the length of the box body, one side of the box body is provided with an inlet 12 that communicates with the guide tube 1, and the side of the box body opposite to the inlet 12 is provided with a side outlet 13.
[0067] In addition, such as Figures 2 to 6 As shown, the first clamping assembly 2 includes a second linear module 15, which includes two linear guides with opposite directions of movement. A first clamping plate 201 is connected to each linear guide, and the first clamping plate 201 has arc-shaped receiving holes 16. The second linear module 15 drives the two first clamping plates 201 to move closer to or further away from the center of the guide tube 1, so that the head of the experimental sample is clamped within the receiving space enclosed by the two receiving holes 16.
[0068] In this embodiment, the second linear module 15 is provided with two linear guides arranged in opposite directions. The first clamping plate 201 has a planar plate structure, and the two receiving holes 16 are arc-shaped. In order to prevent damage to the experimental sample, compressible materials such as cotton or rubber need to be added into the receiving holes 16 to provide cushioning and protection. Secondly, a pressure sensor should also be provided on the first clamping plate 201 to control the extrusion force.
[0069] Furthermore, such as Figure 7As shown, the second clamping assembly 3 includes a sliding plate 301, a second driving part 302 connected to the sliding plate 301, a connecting block 303 disposed at the power output end of the second driving part 302, and a rotating shaft 304 pivotally connected to the connecting block 303. A third driving part 305 is connected to the rotating shaft 304. The third driving part 305 has two movable ends, and a second clamping plate 306 disposed opposite to each of the two movable ends is connected to the two movable ends respectively. In this embodiment, an extension plate 310 is provided on the rotating shaft 304, the third driving part 305 is connected to the extension plate 310, the extension plate 310 is sleeved on the rotating shaft 304, and is fixed by a locking screw.
[0070] In this embodiment, the second drive unit 302 is a hydraulic cylinder or a pneumatic cylinder. The rotating shaft 304 extends along the width direction of the housing 10. Preferably, the third drive unit 305 is a two-jaw pneumatic cylinder, and the second clamping plate 306 is arc-shaped. The two opposing second clamping plates 306 are separated before clamping. When located below the experimental sample, the third drive unit 305 starts to retract.
[0071] Furthermore, such as Figures 2 to 3 As shown, rotating arms 307 are connected to both sides of the rotating shaft 304. A protruding post 308 is pivotally connected to the side of the rotating arm 307 facing the outside of the housing 10. The housing 10 has sliding grooves 309 on both sides corresponding to the rotating arms 307, and the protruding post 308 is located within the sliding groove 309. When the second driving unit 302 drives the connecting block 303 to move, the protruding post 308 slides along the sliding groove 309, causing the second clamping plate 306 to approach the side outlet 13.
[0072] Preferably, such as Figures 2 to 3 As shown, the bottom wall of the box body 10 in this embodiment is also provided with a through lower outlet 14, which communicates with the side outlet 13. The slide 309 includes a first horizontal section 3091 arranged laterally, a vertical section 3092 disposed on the first horizontal section 3091, and a second horizontal section 3093 connected to the other side of the vertical section 3092. The vertical section 3092 is arranged along the height direction of the box body 10. The second horizontal section 3093 extends to one end of the side outlet 13. When the second driving part 302 drives the rotating shaft 304 to slide to the vertical section 3092, the second clamping plate 306 rotates 90°. When the rotating shaft 304 slides to the second horizontal section 3093, the second clamping plate 306 is located at the lower outlet 14 and rotates 180°.
[0073] With this configuration, as the second drive unit 302 drives the rotating shaft 304 to move, when the protrusion 308 slides along the first horizontal section 3091 of the slide groove 309, the second clamping plate 306 opens upwards, facilitating the gripping of the experimental sample. When the protrusion 308 slides to the vertical section 3092 of the slide groove 309, the second clamping plate 306 rotates 90° with the experimental sample, clamping the body of the experimental sample while restraining its head with the connecting rod and the rubber sleeve 6, thus effectively preventing the experimental sample from struggling or moving around.
[0074] Preferably, such as Figure 8 As shown, the top cover 11 is provided with a curved groove 1101, and a sliding slider 1102 is provided in the groove 1101. The slider 1102 is provided in a one-to-one correspondence with the rubber sleeve 6. The connecting member 8 is provided between the rubber sleeve 6 and the slider 1102. The opening of the groove 1101 is provided on the same side as the side outlet 13. When the second clamping plate 306 moves away from the side outlet 13, the connecting member 8 and the slider 1102 disengage from the groove 1101.
[0075] It should be noted that the connecting rod in this embodiment is made of elastic rubber material with a certain amount of elasticity to avoid damage to the experimental sample. When the rotating shaft 304 gradually slides to the second horizontal segment 3093, the connecting piece 8 and the slider 1102 are pulled away from the groove 1101. The box body 10 is provided with a vertical groove 1001 for the connecting rod to pass through. In this embodiment, the slider 1102 is a rectangular block that slides in the groove 1101.
[0076] like Figure 7 As shown, the length of the extension plate 310 in this embodiment is calculated based on the elasticity of the connecting rod. Since the second clamping plate 306 is first pushed out of the box 10 from the side outlet 13, and the slider 1102 disengages from the opening of the top cover 11 from the groove 1101, the second clamping plate 306 carries the experimental sample and rotates again. The opening of the second clamping plate 306 faces downwards, that is, the head of the experimental sample faces downwards. The experimenter holds the connecting rod at one end and fixes the fixing device for fixing the experimental sample on the experimental sample. The clamping range of the second clamping plate 306 can be adaptively avoided according to the shape of the fixing device.
[0077] Secondly, in many experiments, the experimental sample can be directly anesthetized after being grasped. In this embodiment, the head of the second clamping plate 306 clamping column is fixed by the operator manually pulling the rubber sleeve 6, which can realize the injection when the grasping device grasps the sample to the position of the lower outlet 14, and the second clamping plate 306 is released after the anesthesia is completed.
[0078] Furthermore, such as Figure 5As shown, the storage component 5 includes a cylindrical body 501 connected inside the box body 10, support columns 502 spaced apart inside the cylindrical body 501, and several rubber sleeves 6 sleeved on the outside of the support columns 502. The cylindrical body 501 is arranged along the length direction of the box body 10 and the opening faces the guide tube 1. An elastic element 503 is also provided inside the cylindrical body 501. The elastic element 503 is located between the inner wall of the box body 10 and the rubber sleeves 6.
[0079] Still Figure 5 As shown, the elastic element 503 is a telescopic spring. After one rubber sleeve 6 is used, the elastic element 503 gradually pushes the subsequent rubber sleeve 6 to facilitate disengagement. In this embodiment, the rubber sleeve 6 is made of rubber with a small elasticity. When the gripper 703 assembly abuts against the support post 502, it can be easily inserted into the inner ring of the rubber sleeve 6.
[0080] In addition, such as Figure 5 As shown, the sleeve assembly 7 includes a fourth drive unit 701 connected to the movable end of the second linear module 15, a fifth drive unit 702 located at the power output end of the fourth drive unit 701, and a gripper 703 assembly connected to the power output end of the fifth drive unit 702. The gripper 703 assembly includes several grippers 703 that are driven to open and close relative to each other. When the gripper 703 assembly is in the retracted state, the grippers 703 are inserted between the rubber sleeve 6 and the support column 502; the fifth drive unit 702 drives the gripper 703 assembly downward to one side of the guide tube 1, and the fourth drive unit 701 drives the fifth drive unit 702 to rotate 180°. When the grippers 703 are in the extended state, the grippers 703 cover the head of the experimental animal and gradually retract, causing the rubber sleeve 6 to slide down to the neck of the experimental animal.
[0081] Furthermore, the gripper 703 assembly also includes a four-jaw cylinder 705, with the grippers 703 respectively connected to the movable ends of the four-jaw cylinder 705. A baffle is provided at the front end of each gripper 703, and several baffles form a circular retaining ring 704 to prevent the rubber sleeve 6 from sliding backward. A tapered section 7031 is provided at the end of each gripper 703, and the tapered section 7031 gradually decreases in size towards the end. For ease of implementation, the fifth drive unit 702 in this embodiment uses a four-jaw cylinder 705; in other embodiments, a dedicated connecting rod gripper 703 can also be used directly. Figure 5 As shown, the gripper 703 in this embodiment is provided with a tapered section 7031, which facilitates the sleeve 6 to be fitted onto the gripper 703 and to detach when fitted onto the head of the experimental sample.
[0082] The specifications of the rubber sleeve 6 in this embodiment need to be adapted to the selection of the experimental sample. The first clamping plate 201 and the second clamping plate 306 are set according to the smaller experimental sample, and the cotton or rubber protective sleeves mentioned above need to be added at the contact point with the experimental sample.
[0083] In addition, this embodiment also includes a control system, such as a PLC controller. The aforementioned sensors are connected to the control system via signals, and each power source is electrically connected to the control system to achieve the purpose of fully automatic grasping of experimental animals.
[0084] In addition, to increase security, pivotable and outward-folding doors are installed at the side outlet 13 and the lower outlet 14 in this embodiment. By setting the flip doors, the sealing performance of the gripping device is increased.
[0085] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
