Description

Technical Field

[0001] The invention relates to the technical field of panda blood sampling equipment and discloses a panda blood sampling device. Background Art

[0002] The giant panda is a species endemic to China, primarily found in the mountainous regions of Sichuan, Shaanxi, and Gansu. It is a rare and protected species in my country. Captive breeding has significantly increased the captive giant panda population. To protect the health of the giant pandas in captivity, regular blood draws from the pandas' forelimb veins are performed for complete blood and biochemical analysis.

[0003] In the prior art, when collecting blood from a panda, the panda is generally fixed and then the blood is collected manually. When the panda is fixed, the panda will have a large stress reaction, and the person collecting the blood may be scratched by the panda. In order to prevent the blood collectors from being scratched by the panda, they will wear thicker protective clothing. However, this makes it inconvenient for the blood collectors to carry out disinfection and blood collection work, resulting in low blood collection efficiency.

[0004] In order to solve the above problems, a panda blood collection device is proposed. Summary of the Invention

[0005] The present invention aims to provide a panda blood collection device to improve the efficiency of blood collection from pandas.

[0006] To achieve the above-mentioned object, the basic scheme of the present invention is as follows: a panda blood collection device, comprising an arm guard, wherein a plurality of restraint components are provided on the arm guard along its length direction; a plurality of airbag strips are provided on both sides of the arm guard, adjacent airbag strips are connected, and the airbag strips are connected to an air path system;

[0007] A collection port is provided at the bottom of the arm guard, paddles are provided on both sides of the collection port, and an elastic member is provided between the paddles;

[0008] A collection mechanism is provided below the collection port;

[0009] It also includes an input module and a controller electrically connected to the input module. The controller is electrically connected to the collection mechanism and the gas path system.

[0010] The principle and beneficial effects of the basic scheme are as follows: (1) The picks are brought close to each other, and then the arm guard is placed on any limb of the panda through the binding component. The operation time is short, and the blood collector can quickly move away from the panda, reducing the chance of the panda having a stress reaction. When the picks are released, the picks will push away the panda's hair near the collection port, avoiding panda hair being pulled out at the collection location, further reducing the chance of the panda having a stress reaction.

[0011] (2) The gas is delivered to a plurality of airbag strips through the input module, the controller and the control air path system, so as to adapt to limbs of different diameters and act as a cuff in conjunction with the restraint belt.

[0012] (3) The collection mechanism is controlled by the input module and the controller. The collection mechanism works and collects blood through the collection port toward the collection position of the panda. The purpose of intelligent collection is achieved by controlling the collection mechanism through the input module and the controller. The amount of blood collected can be quantified, and the entire process does not require direct operation by the collection personnel. When the panda has a stress response, the harm to the blood collection personnel can be reduced.

[0013] Furthermore, both sides of the guard arm are fixedly connected with a protective plate, the bottom of any one of the protective plates is fixedly connected with a driving member, the output shaft of the driving member is coaxially fixedly connected with a rotating shaft, the rotating shaft is rotatably connected to the guard arm, and the driving member is electrically connected to the controller;

[0014] The restraint assembly includes a winding roller coaxially fixedly connected to the rotating shaft and a through slot opened on the two protective plates. A restraint belt is rotatably connected in the through slot. One end of the restraint belt is fixed on the winding roller, and the other end of the restraint belt is fixed on the winding roller. The fixing directions of the two ends of the restraint belt are opposite.

[0015] Beneficial Effects: In the present invention, a drive element drives the rotating shaft and winding roller to rotate, which rewinds the ends of the restraint strap to tighten the strap, thereby stably attaching the arm guard to the panda's limb. While the strap is attached to the panda's limb, it is remotely controlled via an input module and controller, minimizing the risk of stress reactions from the panda during the strapping process and harming the blood collector.

[0016] Furthermore, the air circuit system includes an air pump, which is connected to a first solenoid valve fixed on the protective plate. The first solenoid valve is connected to any airbag strip, and any airbag strip is connected to a second solenoid valve. The controller is connected to the air pump, the first solenoid valve and the second solenoid valve.

[0017] Beneficial effects: The controller controls the operation of the air pump, which introduces gas into the airbag strip through the first solenoid valve. The gas introduction time can be controlled according to actual needs. When the panda blood collection is completed, the second solenoid valve is opened to release the gas in the airbag strip.

[0018] Furthermore, an arc-shaped hook is provided on the upper part of the paddle, and a Velcro is provided on the hook.

[0019] Beneficial effect: Through the cooperation of the hook and the Velcro, more panda hair can be adhered, and the elastic part moves toward both sides of the opening to expose the skin near the collection port, without having to pull out the panda's hair, thereby reducing the panda's stress response.

[0020] Furthermore, the collection mechanism includes a bracket mounted on the protective arm, a sleeve is slidably fitted on the bracket, a syringe is tapered inside the sleeve, a first electric-controlled cylinder is fixedly connected to one side of the bracket, an output shaft of the first electric-controlled cylinder is fixedly connected to the sleeve, a second electric-controlled cylinder is fixedly connected to the other side of the bracket, the second electric-controlled cylinder is detachably connected to the piston of the syringe, and the first electric-controlled cylinder and the second electric-controlled cylinder are both electrically connected to the controller.

[0021] Beneficial effects: The syringe is fixed by the sleeve, and through the control of the controller, the first electric cylinder drives the sleeve and the syringe to move toward the collection port so that the syringe punctures the panda's vein, and the second electric cylinder drives the piston of the syringe to pull the piston so that the syringe draws blood. Due to the control of the controller, the movement stroke of the first electric cylinder and the second electric cylinder can be controlled to maximize the accuracy of puncture and blood drawing.

[0022] Furthermore, a connecting plate is fixedly connected to the output shaft of the second electric control cylinder, and a clamping plate is fitted in a horizontal sliding manner on the connecting plate. A groove is provided on the piston, and the clamping plate is engaged with the groove.

[0023] Beneficial effect: Through the cooperation of the clamping plate and the groove, the second electric control cylinder and the piston of the syringe can be detachably matched, so that the syringe with the panda's blood collected can be easily removed.

[0024] Furthermore, an elastic layer is provided on the inner side wall of the sleeve.

[0025] Beneficial effect: by squeezing the elastic layer with the syringe, the syringe can be further clamped on the sleeve to ensure the stability of the syringe.

[0026] Furthermore, an inverted U-shaped guide plate is provided on the bracket, a disinfection cavity is opened on the guide plate, the disinfection cavity is connected to a number of disinfection ports, a disinfection plate is slidably fitted in the disinfection cavity, a disinfection shaft is fixedly connected to the disinfection plate and slidably fitted with the disinfection plate, the disinfection shaft is fixedly connected to the sleeve, and the guide plate is clamped to the syringe barrel of the syringe.

[0027] Beneficial effect: When the sleeve moves toward the panda, the sleeve will drive the disinfection shaft and the disinfection plate to squeeze the disinfectant in the disinfection cavity, and the disinfectant will be sprayed toward the vicinity of the collection port through the through hole to disinfect the skin near the collection port.

[0028] Furthermore, a supply box is fixedly connected to the bracket, and the supply box is connected to a one-way valve through a pipeline. The one-way valve is fixed on the guide plate and is connected to the disinfection chamber.

[0029] Beneficial effect: When the first electric control cylinder drives the sleeve to reset, the sleeve drives the disinfection plate and the disinfection shaft to reset, so that a certain negative pressure is generated in the disinfection chamber, and the disinfectant in the supply box is sucked in through the one-way valve to replenish the disinfectant.

[0030] Furthermore, it also includes a battery, which is used to supply power to the gas system and the blood sampling mechanism.

[0031] Beneficial effect: Power is supplied to the gas system and the collection mechanism through the battery. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The following is further described in detail through specific implementation methods:

[0042] The figure marks in the drawings of the specification include: arm guard 11, protective plate 12, through groove 13, roller 14, restraint belt 15, air pump 16, first solenoid valve 17, limit groove 18, airbag strip 21, battery 22, second solenoid valve 23, motor 24, rotating shaft 241, winding roller 242, collection port 31, paddle 32, spring 33, Velcro 34, blood collection mechanism 41, bracket 411, guide plate 412, sleeve 413, second electric control cylinder 414, syringe 415, card plate 416, first electric control cylinder 417, supply box 418, one-way valve 51, disinfection chamber 52, disinfection plate 53, disinfection port 54, disinfection shaft 55.

[0043] The embodiment is basically as shown in the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 , Attachment Figure 5 and attached Figure 6 As shown:

[0044] A panda blood collection device includes an arc-shaped guard arm 11, with a protective plate 12 fixedly connected to both sides by screws. A restraint assembly is provided on the guard arm 11 along its length. The restraint assembly includes a through slot 13 provided on the two protective plates 12, and a roller shaft 14 is rotatably connected in each through slot 13. A restraint belt 15 is sleeved on the roller shaft 14. In this embodiment, a driving member is also included. The driving member is a motor 24. The motor 24 is fixedly mounted on the bottom of the right protective plate 12. A rotating shaft 241 is coaxially fixedly connected to the output shaft of the motor 24. A plurality of winding rollers 242 are coaxially fixedly connected to the rotating shaft 241 along its length. The number of winding rollers 242 is equal to the number of restraint belts 15. One restraint belt 15 corresponds to one winding roller 242. One end of the restraint belt 15 is fixedly connected to one side of the winding roller 242, and the other end of the restraint belt 15 is fixedly connected to the other side of the winding roller 242. That is, the fixing directions of the two ends of the restraint belt 15 are opposite. In this embodiment, an arc-shaped groove is provided on the guard arm 11 for limiting the restraint belt 15 .

[0045] In this embodiment, the arm guard 11 is put on one of the panda's limbs, and then the motor 24 is started to drive the rotating shaft 241 and the winding roller 242 to rotate. The winding roller 242 drives the two ends of the restraint belt 15 to tighten, so that the arm guard 11 is tied to the panda's limb.

[0046] Several airbag strips 21 are fixedly connected to the inner wall side of the guard arm 11, and adjacent airbag strips 21 are connected through pipes. The guard arm 11 is provided with an air path system located at the lower part of the right protective plate 12. The air path system includes an air pump 16 fixedly installed on the protective plate 12. The air pump 16 is connected to a first solenoid valve 17. The first solenoid valve 17 is connected to any airbag strip 21, and any airbag strip 21 is connected to a second solenoid valve 23.

[0047] In this embodiment, the first solenoid valve 17 and the air pump 16 are opened, and the air pump 16 injects gas into the airbag strips 21 through the first solenoid valve 17 so that all the airbag strips 21 are filled with gas. Under the action of the gas, the airbag strips 21 expand and squeeze the panda's limbs, and cooperate with the restraint belt 15 to form a compression belt to squeeze the panda's limbs, thereby facilitating subsequent blood drawing.

[0048] A collecting port 31 is provided on the bottom side wall of the arm guard 11 , and paddles 32 are horizontally slidably connected to both sides of the collecting port 31 , and an arc-shaped hook is fixedly connected to the upper part of the paddle 32 , and a Velcro 34 is bonded and fixed to the hook. Several elastic members are provided between the paddles 32 , and the elastic members are springs 33 .

[0049] In this embodiment, the spring 33 is pre-compressed to bring the two paddles 32 closer together. After the arm guard 11 is put on the panda's limb (at this time, the Velcro 34 adheres to the panda's hair near the collection port 31), the paddles 32 are released to move the panda's hair near the collection port 31 toward the two sides of the collection port 31 to expose the panda's skin.

[0050] This embodiment also includes an input module, comprising a Bluetooth transmitter and a Bluetooth receiver. The Bluetooth receiver is mounted on the arm guard 11 and electrically connected to a controller, which can be a conventional PLC or single-chip microcomputer. The Bluetooth transmitter is signal-connected to an information input module, such as a mobile phone or computer. The design can be tailored to actual needs, with remote transmission methods. For example, a mobile phone can send control information to the Bluetooth receiver via the Bluetooth transmitter, and the controller performs control operations based on this control information. In this embodiment, the controller is electrically connected to the air pump 16, the first solenoid valve 17, the second solenoid valve 23, and the motor 24.

[0051] In this embodiment, for example, after the arm guard 11 is placed on a panda's limb, the blood collector transmits restraint and inflation information to a Bluetooth transmitter via a mobile phone. Upon receiving the restraint information, the controller controls the motor 24, which drives the rotating shaft 241 and the reel 242 to tighten the restraint strap 15, thereby stabilizing the arm guard 11 on the panda's limb. Upon receiving the inflation information, the controller controls the air pump 16 and the first solenoid valve 17 to open, injecting gas into the airbag strip 21 until the strip 21 expands to a certain degree. The controller then controls the air pump 16 to shut down and the first solenoid valve 17 to close. In this embodiment, the air pump 16 is a micro-pump 16, and the motor 24 is a micro-motor 24, both of which are currently available. When deflation is required, deflation information is input to the controller, which controls the second solenoid valve 23 to open, releasing the gas from the airbag strip 21.

[0052] A collection mechanism is provided below the collection port 31, and the collection mechanism includes a bracket 411 fixedly mounted on the guard arm 11, a sleeve 413 fixedly connected to the bracket 411, an elastic layer made of elastic material is provided on the inner wall of the sleeve 413, and a syringe 415 is matched with the inner taper of the sleeve 413, the needle tube of the syringe 415 faces the collection port 31, and the piston of the syringe 415 faces below the collection port 31. The sleeve 413 is matched with the taper of the syringe 415 and the elastic layer so that the syringe 415 can be removed from the sleeve 413. A first electrically controlled cylinder 417 is fixedly connected to bracket 411. The output shaft of first electrically controlled cylinder 417 is fixedly connected to sleeve 413. A second electrically controlled cylinder 414 is fixedly connected to bracket 411. The output shaft of second electrically controlled cylinder 414 is fixedly connected to a support plate. A clamping plate 416 is horizontally slidably connected to the support plate. The piston of syringe 415 has a groove, and clamping plate 416 extends into the groove to engage with the groove. Both first and second electrically controlled cylinders 417 and 414 are electrically connected to a controller.

[0053] In this embodiment, when blood collection information is input to the controller via the input module, the controller controls the first electrically controlled cylinder 417 to move the sleeve 413 upward, which in turn drives the syringe 415 upward to puncture the vein at the collection port 31. The second electrically controlled cylinder 414 then drives the support plate and the clamping plate 416 downward, thereby driving the piston of the syringe 415 downward to draw blood from the panda. In this embodiment, the controller controls the movement of the first electrically controlled cylinder 417 and the second electrically controlled cylinder 414, thereby determining the puncture depth and the amount of blood drawn, achieving relatively precise control. After blood collection is complete, removal information is input to the controller via the input module, causing the first electrically controlled cylinder 417 to disengage the sleeve 413 and syringe 415 from the panda.

[0054] After completing the blood collection from the panda, the input module and controller are used to control the second solenoid valve 23 to deflate the restraint strip, and to control the motor 24 to drive the rotating shaft 241 and the winding roller 242 to rotate in opposite directions, so that the restraint belt 15 is loosened, making it easier for the arm guard 11 to separate from the panda's limbs. The blood collection personnel then reclaim the arm guard 11, and disinfect and press the collection site on the panda to reduce bleeding at the collection site.

[0055] A guide plate 412 is fixedly connected to the bracket 411. A through hole is formed in the guide plate 412, into which the barrel of the syringe 415 extends. As the syringe 415 moves upward, it is guided by the guide plate 412, ensuring stable movement. A disinfection chamber 52 is defined in the guide plate 412. A disinfection plate 53 slides vertically within the disinfection chamber 52. The disinfection plate 53 is provided with a disinfection shaft 55, which slides with the guide plate 412 and is fixedly connected to the sleeve 413. Several disinfection ports 54 are formed in the guide plate 412, communicating with the disinfection chamber 52. A supply tank 418 is fixedly connected to the bracket 411. This supply tank 418 is connected to a one-way valve 51 via a pipeline. The one-way valve 51 is fixedly mounted on the guide plate 412 and communicates with the disinfection chamber 52.

[0056] In this embodiment, when the sleeve 413 moves upward, it drives the disinfection shaft 55 and the disinfection plate 53 to squeeze the disinfectant in the disinfection chamber 52 and spray it onto the panda's skin near the collection port 31 through the disinfection port 54. When the sleeve 413 moves downward, it drives the disinfection shaft 55 and the disinfection plate 53 downward, and draws disinfectant from the supply tank 418 through the one-way valve 51 to replenish the disinfection chamber 52.

[0057] In this embodiment, a battery 22 is fixedly installed below the left protective plate 12, and the battery 22 supplies power to the input module, the controller, the collection mechanism and the gas circuit system.

[0058] In this embodiment, the collection mechanism is stabilized by the first electric cylinder 417 and the second electric cylinder 414, which can prevent the panda from touching the syringe 415 and minimize damage to the panda. The air system and the motor 24 are installed on the west side of the protective plate 12. When the panda drives the guard arm 11 to move horizontally, the probability of damage to the air system and the motor 24 can be reduced, thereby ensuring the safety of the entire device.

[0059] In this embodiment, the entire blood collection device is remotely controlled to avoid harm to blood collectors and reduce the probability of pandas having a stress reaction.

[0060] The above is only an embodiment of the present invention, and common knowledge such as the specific structure and / or characteristics of the scheme is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
