[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0048] Example 1: As shown in the figure, a smart blood collection device for fish includes an operating table 1, and also includes...

[0049] Anesthesia pool 2 is set on operating table 1. Anesthesia pool 2 contains anesthetic solution, which is ethyl m-aminobenzoate methanesulfonate solution.

[0050] The support platform 3 is set on the operating platform 1 via the lifting mechanism 13 and is located above the anesthesia pool 2. The support platform 3 is equipped with a limiting mechanism 4 for fixing the fish body.

[0051] The blood collection syringe 5 is mounted on the operating table 1 via the displacement mechanism 14, giving the blood collection syringe 5 freedom of movement in the up and down, left and right, front and back and circumferential directions. The blood collection syringe 5 is also connected to a drainage tube 6.

[0052] The turntable 7 is rotatably connected to the operating table 1 via the rotating mechanism 15. The turntable 7 has multiple placement holes evenly arranged circumferentially, and centrifuge tubes 8 are placed at the placement holes.

[0053] The lifting plate 9 is mounted on the operating table 1 via the lifting mechanism 16. The lifting plate 9 is provided with a needle 10 for inserting into the centrifuge tube 8, and the needle 10 is connected to the centrifuge tube 8.

[0054] The image acquisition module 11 is set on the operating table 1 and is used to acquire images of the fish on the support platform 3 and feed them back to the control module 12. The control module 12 is used to control the operation of the lifting mechanism 13, the displacement mechanism 14, the rotation mechanism 15 and the lifting mechanism 16.

[0055] The lifting mechanism 13 includes a base plate 17, a first motor 18, a first lead screw 19, a lead screw nut 20, and a fixing plate 21. The base plate 17 is vertically fixed on the operating table 1. The first motor 18 is fixed at the upper end of the base plate 17. The first lead screw 19 is coaxially fixed with the output shaft of the first motor 18. The lead screw nut 20 is fixed inside the fixing plate 21 and threadedly engaged with the first lead screw 19. A guide unit 22 is also provided between the fixing plate 21 and the base plate 17. The support platform 3 is fixed to the fixing plate 21 through an L-shaped plate 23.

[0056] In the above structure, a screw mechanism is used to achieve precise and stable lifting and lowering movement. The first motor 18 drives the first screw 19 to rotate. Through the threaded engagement with the screw nut 20, the fixed plate 21 and the support platform 3 produce smooth lifting and lowering movements with high precision and stable movement. The guide unit 22 guides the fixed plate 21 and the support platform 3 to produce only vertical movements. Combined with the screw mechanism, the movement direction and precision of the entire lifting system are well controlled.

[0057] The intelligent blood collection device for fish also includes a cover plate 24 for covering the anesthesia pool 2. The cover plate 24 is mounted on the operating table 1 via a sliding mechanism 25. The sliding mechanism 25 includes a guide rail 26, a slider 27, a second lead screw 28, and a nut seat 29. The guide rail 26 is fixed on the operating table 1 and located on one side of the anesthesia pool 2. The slider 27 is slidably mounted on the guide rail 26. The second lead screw 28 is rotatably mounted on the operating table via a bearing seat and located on the other side of the anesthesia pool 2. The nut seat 29 is threadedly engaged with the second lead screw 28. The cover plate 24 is connected between the slider 27 and the nut seat 29. A linkage mechanism 30 is provided between the second lead screw 28 and the first lead screw 19. The linkage mechanism 30 is used to drive the second lead screw 28 to rotate forward when the support platform 3 moves upward, so that the cover plate 24 covers the anesthesia pool 2. When the support platform 3 moves downward, it drives the second lead screw 28 to rotate in reverse, so that the cover plate 24 moves away from the anesthesia pool 2.

[0058] In the above structure, the slider 27 and guide rail 26 are used to achieve smooth sliding of the cover plate 24. The slider 27 can move closer to or away from the anesthesia pool 2 under the guidance of the guide rail 26, thereby driving the cover plate 24 to produce corresponding movements. The second lead screw 28 and nut seat 29 are used to drive the slider 27 toward or away from the anesthesia pool 2. The second motor controls the forward and reverse rotation of the second lead screw 28, driving the nut seat 29 and slider 27 to produce corresponding movements, which has the characteristics of high transmission accuracy and smooth movement. The bearing seat is used to allow the second lead screw 28 to rotate freely, reducing the frictional resistance in mechanical movement and improving the movement efficiency of the mechanism. The linkage mechanism 30 can link the rotation of the second lead screw 28 with the rotation of the first lead screw 19. In this way, when the support platform 3 is raised or lowered, it can automatically drive the cover plate 24 to move in coordination with it, closing or opening the anesthesia pool 2 to prevent the anesthesia pool from being contaminated, making the system highly automated.

[0059] The linkage mechanism 30 includes a first bevel gear 31, a second bevel gear 32, a commutator 33, a first pulley 34, a second pulley 35, and a synchronous belt 36. The lower end of the first lead screw 19 extends downwards from the operating table 1 and meshes with the first bevel gear 31. The second bevel gear 32 meshes with the first bevel gear 31, and a rotating shaft is coaxially fixed on the second bevel gear 32. The commutator 33 is fixed below the operating table 1 and has an input shaft and an output shaft. The input shaft of the commutator 33 is fixed to the rotating shaft, and the output shaft of the commutator 33 is coaxially fixed to the first pulley 34. The second pulley 35 is coaxially fixed to the second lead screw 28, and the synchronous belt 36 connects the first pulley 34 and the second pulley 35.

[0060] In the above structure, bevel gear transmission is used to achieve motion transmission and speed matching between the first lead screw 19 and the second lead screw 28. Bevel gears have variable gear ratios; by selecting first bevel gears 31 and second bevel gears 32 with different gear ratios, the rotational speeds of the first lead screw 19 and the second lead screw 28 can be matched. A commutator 33 is used to convert the axial motion of the first lead screw 19 into the rotational motion of the second lead screw 28, allowing it to achieve the corresponding function by either lifting or rotating the first lead screw 19. A pulley and a synchronous belt 36 are used to drive the second lead screw 28. The output shaft of the commutator 33 drives the first pulley 34 to rotate, which in turn drives the second pulley 35 via the synchronous belt 36, ultimately driving the second lead screw 28, which is coaxial with the second pulley 35, to rotate, thereby driving the sliding of the cover plate 24.

[0061] In practice, the steps are as follows:

[0062] 1. When it is necessary to perform blood collection on the fish, the first motor 18 first drives the first lead screw 19 to rotate, thereby lowering the support platform. When the first lead screw 19 rotates, it will cause the second bevel gear 32 to rotate through the first bevel gear 31.

[0063] 2. The rotation of the second bevel gear 32 drives the shaft and the input shaft of the commutator 33 to rotate, while the output shaft of the commutator 33 rotates in the opposite direction, thereby driving the first pulley 34 to rotate. Since the first pulley 34 and the second pulley 35 are connected by the synchronous belt 36, when the first pulley 34 rotates, it will cause the second pulley 35 to rotate, and the rotation of the second pulley 35 drives the second lead screw 28 to rotate forward.

[0064] 3. The forward rotation of the second lead screw 28 causes the nut seat 29 to move to one side, driving the slider 27 to slide away from the anesthesia pool 2 on the guide rail 26, which in turn drives the cover plate 24 to open the anesthesia pool 2. At this time, the support platform 3 is completely lowered and the cover plate 24 is completely opened to open the anesthesia pool 2.

[0065] 4. After the operation is completed, the fish body needs to be removed from the anesthesia pool 2 and the cover plate 24 needs to be closed. At this time, the first motor 18 drives the first lead screw 19 to reverse, and the movement direction of the related mechanisms is opposite to the above process. Finally, the second lead screw 28 reverses, causing the cover plate 24 to move under the drive of the slider 27, closing the anesthesia pool 2, until the support platform 3 is also raised and lowered to the highest position under the drive of the first lead screw 19.

[0066] 5. At this point, a complete work cycle is completed. The lifting and lowering of the support platform 3 realizes the removal and return of the fish body, while the opening and closing of the cover plate 24 is coordinated with the lifting and lowering of the support platform 3 to automatically complete the opening and closing of the anesthesia pool 2.

[0067] This structure employs a motor drive and mechanical linkage to achieve coordinated and precise control of multiple mechanisms, which greatly simplifies the complexity of the control system and reduces its cost.

[0068] The displacement mechanism 14 includes a first crossbeam 37, a first movable seat 38, a second crossbeam 39, a second movable seat 40, a longitudinal beam 41, a third movable seat 42, and a clamping seat 43. The first crossbeam 37 is fixed on the operating table 1. The first movable seat 38 is movably connected to the first crossbeam 37 and can move left and right. A first driving assembly 56 for driving the first movable seat 38 to move left and right is provided between the first movable seat 38 and the first crossbeam 37. The second crossbeam 39 is horizontally fixed to the first movable seat 38 and can move back and forth. A second drive assembly 57 for driving the second moving seat 40 to move back and forth is provided on the second crossbeam 39 and between the second moving seat 40 and the second crossbeam 39. The longitudinal beam 41 is vertically fixed on the second moving seat 40. The third moving seat 42 is movable up and down and connected to the longitudinal beam 41. A third drive assembly 58 for driving the third moving seat 42 to move up and down is provided between the third moving seat 42 and the longitudinal beam 41. The clamping seat 43 is connected to the third moving seat 42 through the rotating assembly 44. The blood collection syringe 5 is fixed on the clamping seat 43.

[0069] In the above structure, a modular structure is adopted, including a first crossbeam 37, a first movable seat 38, a second crossbeam 39, a second movable seat 40, a longitudinal beam 41, a third movable seat 42, and a clamping seat 43. A first drive assembly 56, a second drive assembly 57, and a third drive assembly 58 are set between each movable seat to realize the design of three-dimensional precise positioning motion control. It has the advantages of wide working range, high positioning accuracy, stable mechanism and easy maintenance. It can flexibly and accurately realize the extensive movement of the syringe in three-dimensional space. The rotating assembly 44 is used to drive the blood collection syringe 5 to rotate, so as to better adapt to the fish body and perform blood collection operation.

[0070] The first drive assembly 56 includes a first drive motor, a first belt and two first drive wheels. The two first drive wheels are fixed to the first crossbeam 37 with a left-right interval. The first drive motor is fixed to the first crossbeam 37 and is used to drive one of the first drive wheels to rotate. The first belt is wound between the two first drive wheels and is fixed to the first movable seat 38. A first slide rail assembly is also provided between the first movable seat 38 and the first crossbeam 37.

[0071] The second drive assembly 57 includes a second drive motor, a second belt and two second drive wheels.

The second drive motor is fixed to the second crossbeam 39 and is used to drive one of the second drive wheels to rotate. The second belt is wound between the two second drive wheels and is fixed to the second movable seat 40. A second slide rail assembly is also provided between the second movable seat 40 and the second crossbeam 39.

[0072] The third drive assembly 58 includes a third drive motor, a third belt, and two third drive wheels. The two third drive wheels are fixedly mounted on the longitudinal beam 41 at an interval. The third drive motor is fixed to the upper end of the longitudinal beam 41 and is used to drive the upper third drive wheel to rotate. The third belt is wound between the two third drive wheels and is fixed to the third movable seat 42. A third slide rail assembly is also provided between the third movable seat 42 and the longitudinal beam 41.

[0073] The rotating assembly 44 includes a rotating motor 45, which is fixed on the third moving seat 42. The clamping seat 43 includes a mounting plate 46 and two clamping plates 47. The mounting plate 46 is fixed to the output shaft of the rotating motor 45. The two clamping plates 47 are respectively fixed to the upper and lower ends of the mounting plate 46. Each clamping plate 47 is provided with a clamping hole 48 and a notch 49 for connecting the clamping hole 48 to the outside. Each clamping plate 47 is also screwed with a locking bolt 50.

[0074] In the above structure, this drive assembly design using belt drive and slide rail guidance, along with the clamping seat 43 structure driven by the rotary motor 45, has the following advantages:

[0075] 1. Smooth and precise movement: The belt drive ensures smooth and continuous movement of the moving seat, while the slide rail guide further improves movement stability, enabling the syringe to achieve precise and smooth positioning and blood collection.

[0076] 2. Flexible and convenient drive: Each drive component independently drives a moving seat, which makes its motion control flexible and independent, facilitates the coordinated control of different moving seats, and expands the control freedom of the entire system.

[0077] 3. The structure is simple and reliable. The belt drive and slide rail assembly are simple in structure, easy to use and reliable, which reduces the failure rate of the system and facilitates inspection and maintenance.

[0078] The syringe is held in place by two clamping plates 47 and locking bolts 50, which gives the blood collection syringe 5 strong stability and detachability, and facilitates precise control of the syringe position during blood collection.

[0080] In the above structure, cylinder 52 can generate continuous and stable thrust, enabling the lifting plate 9 to achieve precise and stable upward and downward movement, thereby driving the insertion needle 10 to insert into or move away from the centrifuge tube 8. When blood is taken from different fish, the insertion needle 10 can be replaced to prevent cross-contamination.

[0082] In the above structure, this design, which adds a liquid storage container 54, an infusion pump 53, and a three-way valve 55 to the blood collection system to achieve automatic liquid infusion of the blood collection syringe, has the following advantages:

[0083] 1. Continuous and stable infusion: The infusion pump 53 can continuously and stably deliver the anticoagulant solution from the reservoir 54 to the syringe, so that the syringe can continuously inject liquid without affecting the blood collection process due to liquid interruption. The anticoagulant can effectively inhibit the activity of blood coagulation factors and prevent the formation of clots in the collected blood during collection and transportation.

[0084] 2. The flow rate is controllable. The flow rate of the infusion pump 53 can be adjusted in real time through the control system. This allows for precise control of the fluid injection flow rate according to changes in the blood collection situation, ensuring the blood collection effect.

[0085] 3. Fast response speed: Compared with manual injection, automated infusion systems can respond quickly and adjust the fluid flow rate, which greatly improves the continuity and efficiency of blood collection operations.

[0086] 4. Reduced manual operation: Automated liquid delivery systems can replace manual liquid delivery operations, which greatly reduces the workload of operators, improves work efficiency, and reduces errors caused by manual operation.

[0087] The limiting mechanism 4 includes multiple straps fixed on both sides of the support platform 3, which can be used to bind the fish after it is placed on the support platform 3.

[0088] The second objective of this invention is to provide a method for using the intelligent blood collection device for fish based on Embodiment 1, comprising the following steps:

[0089] Step 1: Place the fish on the support platform and limit its position using the limiting mechanism;

[0090] Step 2: Use the lifting mechanism to immerse the fish in the anesthesia pool for 3-7 minutes to induce anesthesia;

[0091] Step 3: After anesthetizing the fish, raise the support platform using the lifting mechanism;

[0092] Step 4: Use the image acquisition module set on the control panel to acquire images of the fish and send the acquired images back to the control module;

[0093] Step 5: The control module analyzes the fish image, determines the blood collection location, and controls the displacement mechanism to drive the blood collection syringe to the blood collection location;

[0094] Step 6: Insert the blood collection syringe into the fish to collect blood, and at the same time open the drainage tube connected to the blood collection syringe to drain the blood;

[0095] Step 7: Control the rotating mechanism to rotate the turntable frame, rotate the centrifuge tube to the blood collection station, control the lifting mechanism to drive the lifting plate to descend, insert the needle into the current centrifuge tube, and realize the connection between the blood collection syringe and the centrifuge tube;

[0096] Step 8: After the current centrifuge tube has finished collecting blood, the lifting mechanism drives the lifting plate to rise, the needle separates from the centrifuge tube, the turntable rotates at an angle, and the next centrifuge tube moves to the blood collection station. Repeat step 7 until blood collection is finished.

[0097] This blood collection method uses image recognition to accurately locate the blood collection site and coordinates the control of the blood collection syringe through various drive mechanisms to ensure continuous and stable blood collection and automatic tube replacement. Because the centrifuge tube is in a negative pressure environment, the entire blood collection process is completed automatically. It has the advantages of high positioning accuracy, high degree of automation, high blood collection efficiency, fast response speed, good continuity, strong stability, reduced human error, and simplified operation, and can achieve efficient, accurate and continuous automatic blood collection.

[0098] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
