Technical Field

[0001] The present invention relates to the technical field of blood collection devices, and particularly to a veterinary blood collection device for livestock farming. Background Art

[0002] In the field of livestock farming, the health monitoring and disease diagnosis of animals are key links to ensure farming efficiency and animal welfare. As an important diagnostic method, blood testing can provide key information on various aspects such as the physiological state, nutritional status, and disease infection of animals. Therefore, accurately and efficiently collecting animal blood samples is crucial for veterinarians' diagnosis and treatment decisions.

[0003] The patent with the publication number CN221865705U relates to a blood collection device for livestock veterinarians with a disinfection function, including a blood collection tube. A piston rod is arranged inside the blood collection tube. A blood collection needle is installed at the bottom position of the blood collection tube. A quantitative mechanism is arranged on the surface of the blood collection tube. The quantitative mechanism consists of a quantitative component and a guide rod. A stable support mechanism is arranged outside the blood collection tube. The stable support mechanism consists of a stable support component and a buffer pad. A disinfection mechanism is arranged outside the blood collection needle. The disinfection mechanism consists of an alcohol cotton and a connecting component. This device makes the blood collection device more functional during use, improves the stability of the blood collection device during use, and also improves the convenience of quantitative blood collection of the blood collection device. However, during the process of collecting blood from animals, it is easy for the blood collection needle to fail to be firmly fixed due to the shaking of the animal, and thus it is easy to cause harm to the animal during blood collection. Therefore, a veterinary blood collection device for livestock farming is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a veterinary blood collection device for livestock farming in view of the above deficiencies in the prior art.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a veterinary blood sampling device for animal husbandry, comprising a shell, the bottom of the shell is fixedly connected with a suction cup, the inner wall of the shell is slidably connected with a pull handle, the inner wall of the shell is slidably connected with a straight rod 1, the inner wall of the shell is fixedly connected with a disc, the bottom of the disc is fixedly connected with an inner barrel, the inner wall of the shell is fixedly connected with a fixed groove, the inner wall of the pull handle is fixedly connected with an arc plate, the bottom of the straight rod 1 is fixedly connected with a circular rubber plate, the inner wall of the fixed groove is provided with a needle tube, the bottom of the pull handle is slidably connected with an L-shaped plate, the top of the disc is fixedly connected with a support plate 1, the inner wall of the support plate 1 is rotatably connected with a rotating plate, the inner wall of the disc is slidably connected with a semicircular plate, the inner wall of the disc is slidably connected with a straight rod 2 through a spring, the inner wall of the shell is provided with a disinfection device for sterilization, and the outer wall of the shell is fixedly connected with a support plate 1.

When starting to draw blood from livestock, the hair of the livestock where blood needs to be drawn is cleaned first to ensure that the skin surface is clean, so that the device can be firmly fixed on the skin surface of the livestock, avoiding the pain of blood drawing during the blood drawing process, causing the livestock to shake due to emotional excitement, resulting in damage to the livestock by the needle. At the same time, the livestock can be automatically acupunctured, so that the depth, angle and position of the acupuncture can be accurately controlled, reducing the situation of blood drawing failure or improper blood drawing site due to human operation errors.

[0006] Preferably, the disinfection device includes a square block fixedly connected to the inner wall of the housing. A first sliding rod is slidably connected to the inner wall of the housing through a spring. A first inclined block is fixedly connected to the rear of the first sliding rod. An inclined plate is slidably connected to the inner wall of the inner barrel. A disinfection box is fixedly connected to the inner wall of the housing. A second sliding rod is slidably connected to the inner wall of the disinfection box through a spring. A second inclined block is fixedly connected to the top of the second sliding rod. A pressing plate is fixedly connected to the bottom of the second sliding rod. A liquid spraying pipe is fixedly connected to the bottom of the disinfection box.

The circumferential surface of the first sliding rod is slidably connected to the inner wall of the inner barrel. The front of the inclined plate is in contact with the rear of the second inclined block. The surface of the pressing plate is in contact with the inner wall of the disinfection box. When performing vacuum pumping for fixation, the first straight rod drives the inclined strip plate to move upward. The inclined strip plate is above the first inclined block, so that the circular rubber plate cannot move downward, fixing the position of the circular rubber plate and avoiding the situation that the circular rubber plate is pulled downward and reset due to the vacuum negative pressure generated by pumping, thus causing instability during blood collection. At the same time, the second sliding rod moves to drive the pressing plate to move, so that the iodophor stored in the disinfection box can be sprayed onto the skin surface of the puncture through the liquid spraying pipe, reducing the manual operation link of spraying iodophor and improving the efficiency of blood collection work.

At the same time, when the first sliding rod is fully pulled out, the notch of the exhaust plug will be in contact with the outside, so that the outside air flows into the interior of the housing, making the air pressure inside the housing communicate with the outside, and then the device can be detached.

[0008] Adopting the above technical solutions, the present invention can bring the following beneficial effects: 1. This veterinary blood collection device for livestock farming operates through the cooperation of a housing, a suction cup, a pull handle, a first straight rod, a disc, an inner barrel, a fixing groove, an arc-shaped plate, a round rubber plate, a syringe, an L-shaped plate, a first support plate, a rotating plate, a semi-circular plate, and a second straight rod. When starting to collect blood from livestock, first clean the hair at the blood collection site of the livestock to ensure the cleanliness of the skin surface, so that the device can be firmly fixed on the skin surface of the livestock, avoiding the situation that during the blood collection process, the stinging pain of blood collection causes the livestock to become agitated and shake, resulting in the needle causing harm to the livestock. At the same time, it can automatically puncture the livestock, enabling precise control of the puncture depth, angle, and position, reducing the situation of blood collection failure or improper blood collection site caused by human operation errors.

This veterinary blood collection device for livestock farming operates through the cooperation of a square block, a first sliding rod, a first inclined block, an inclined plate, a disinfection box, a second sliding rod, a second inclined block, a pressing plate, a liquid spraying pipe, and an inclined strip plate. When performing vacuum pumping for fixation, the first straight rod drives the inclined strip plate to move upward. The inclined strip plate is above the first inclined block, so that the round rubber plate cannot move downward, fixing the position of the round rubber plate and avoiding the situation that the vacuum negative pressure generated by pumping pulls the round rubber plate downward to reset, resulting in instability during the blood collection process. At the same time, the second sliding rod moves to drive the pressing plate to move, so that the iodophor stored in the disinfection box can be sprayed onto the skin surface of the puncture site through the liquid spraying pipe, reducing the manual operation link of spraying iodophor and improving the efficiency of blood collection work.

[0010] 3. This veterinary blood collection device for livestock farming operates through the cooperation of a straight plate, an elastic telescopic plate, a scraper, a fixing rod, a second support plate, a sliding block, and an exhaust plug. When spraying iodophor, it can automatically apply the sprayed iodophor, making the iodophor contact the skin of the blood collection site more fully, deeply removing dirt, grease, and microorganisms on the skin surface, further reducing the complexity of the worker's operation and improving the worker's work efficiency. At the same time, when the first sliding rod is fully pulled out, the notch of the exhaust plug will contact the outside, allowing the outside air to flow into the interior of the housing, making the air pressure inside the housing communicate with the outside, and thus enabling the device to be detached.

[0013] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0014] Please refer to Figures 1 - 9One embodiment of the present invention is: a veterinary blood sampling device for animal husbandry, comprising a shell 1, a suction cup 2 is fixedly connected to the bottom of the shell 1, a pull handle 3 is slidably connected to the inner wall of the shell 1, and a straight rod 4 is slidably connected to the inner wall of the shell 1. When starting to draw blood from the livestock, the hair of the part of the livestock where blood is to be drawn is first cleaned to ensure that the skin surface is clean. After the preparation work is completed, the suction cup 2 is adsorbed on the skin surface where blood is to be drawn. At this time, the straight rod 4 is pulled by the handle, and the movement of the straight rod 4 drives the circular rubber plate 9 to move, so that the air inside the shell 1 can be sucked away, so that the inside of the shell 1 is in a vacuum state, so that the device can be firmly fixed. The skin surface of livestock is prevented from shaking due to the pain of blood collection during blood collection, which may cause the livestock to be excited and shake, and the needle may cause harm to the livestock. The inner wall of the outer shell 1 is fixedly connected with a disc 5, and the bottom of the disc 5 is fixedly connected with an inner barrel 6. The inner wall of the outer shell 1 is fixedly connected with a fixed groove 7, and the inner wall of the pull handle 3 is fixedly connected with an arc plate 8. The bottom of the straight rod 4 is fixedly connected with a round rubber plate 9. The inner wall of the fixed groove 7 is provided with a needle tube 10. The bottom of the pull handle 3 is slidably connected with an L-shaped plate 11. The top of the disc 5 is fixedly connected with a support plate 12, and the inner wall of the support plate 12 is rotatably connected with a rotating plate 13. The inner wall of the disc 5 is slidably connected with a semicircular plate 14. The inner wall of the housing 1 is slidably connected with a straight rod 2 15 through a spring, the inner wall of the housing 1 is provided with a disinfection device 16 for sterilization, the inner wall of the housing 1 is provided with a smearing device 17 for cleaning the hair, the circumferential surface of the straight rod 1 4 is slidably connected with the disc 5, the inner wall of the inner barrel 6 is in contact with the circular rubber plate 9, the right side of the arc plate 8 is in contact with the circumferential surface of the housing 1, the needle tube 10 is in contact with the top of the L-shaped plate 11, the bottom of the rotating plate 13 is in contact with the top of the straight rod 2 15, the bottom of the semicircular plate 14 is in contact with the top of the needle tube 10, and the circular rubber plate 9 moves upward to contact with the straight rod 2 15, and generates an extrusion force on the straight rod 2 15 and pushes the straight rod 2 15 to move upward The straight rod 15 moves upward and contacts with the rotating plate 13, and pushes the rotating plate 13 to rotate counterclockwise. The rotating plate 13 rotates and contacts with the semicircular plate 14 and generates an extrusion force on the semicircular plate 14, so that the semicircular plate 14 moves downward. The downward movement of the semicircular plate 14 pushes the needle tube 10 to move downward, so that the livestock can be automatically acupunctured, so that the depth, angle and position of the acupuncture can be accurately controlled, and the situation of blood collection failure or improper blood collection site caused by human operation errors can be reduced. After the acupuncture is completed, the handle 3 is pulled, and the movement of the handle 3 drives the L-shaped plate 11 to move. The movement of the L-shaped plate 11 will drive the blood drawing handle of the needle tube 10 to move, and then the livestock blood can be collected.

[0015] The disinfection device 16 includes a square block 161 which is fixedly connected to the inner wall of the outer shell 1. A first sliding rod 162 is slidably connected to the inner wall of the outer shell 1 through a spring. A first inclined block 163 is fixedly connected to the rear part of the first sliding rod 162. An inclined plate 164 is slidably connected to the inner wall of the inner barrel 6. When performing vacuum pumping and fixing, the first straight rod 4 drives the inclined strip plate 1610 to move upward. When the inclined strip plate 1610 moves upward, it will contact the first inclined block 163 and exert a squeezing force on the first inclined block 163, forcing the first inclined block 163 to move forward. The forward movement of the first inclined block 163 drives the first sliding rod 162 to move, and the movement of the first sliding rod 162 will cause the spring to stretch. After the first inclined block 163 moves, the inclined strip plate 1610 continues to move until it reaches the top of the first inclined block 163. At this time, after the first inclined block 163 is no longer in contact with the inclined strip plate 1610, the spring resets and drives the first sliding rod 162 to move backward. The movement of the first sliding rod 162 drives the first inclined block 163 to move. At this time, the inclined strip plate 1610 is above the first inclined block 163, so that the circular rubber plate 9 cannot move downward, and the position of the circular rubber plate 9 can be fixed, avoiding the situation that the circular rubber plate 9 is pulled downward and reset by the vacuum negative pressure generated by pumping, which may cause instability during blood collection. A disinfection box 165 is fixedly connected to the inner wall of the outer shell 1. A second sliding rod 166 is slidably connected to the inner wall of the disinfection box 165 through a spring. A second inclined block 167 is fixedly connected to the top of the second sliding rod 166. A pressing plate 168 is fixedly connected to the bottom of the second sliding rod 166. A liquid spraying pipe 169 is fixedly connected and communicated with the bottom of the disinfection box 165. An inclined strip plate 1610 is fixedly connected to the inner wall of the first straight rod 4. The circumferential surface of the first sliding rod 162 is slidably connected to the inner wall of the inner barrel 6. The front part of the inclined plate 164 is in contact with the rear part of the second inclined block 167. The surface of the pressing plate 168 is in contact with the inner wall of the disinfection box 165. At the same time, when the circular rubber plate 9 moves, the circular rubber plate 9 will contact the inclined plate 164 and contact the inclined surface of the inclined plate 164, and then push the inclined plate 164 forward. The forward movement of the inclined plate 164 will contact the second inclined block 167 and exert a squeezing force on the second inclined block 167, forcing the second inclined block 167 to move downward. The downward movement of the second inclined block 167 drives the second sliding rod 166 to move, and the movement of the second sliding rod 166 drives the pressing plate 168 to move, so that the iodophor stored inside the disinfection box 165 can be sprayed onto the skin surface of the needle insertion through the liquid spraying pipe 169, reducing the link of manually spraying iodophor, and improving the efficiency of blood collection work. When the blood collection is completed, pull the pull rod provided on the surface of the first sliding rod 162 to release the limit on the circular rubber plate 9.

[0016] Working principle: When starting to collect blood from livestock, first clean the hair at the blood collection site of the livestock to ensure the cleanliness of the skin surface. After the preparatory work is completed, adsorb the suction cup 2 on the skin surface for blood collection. At this time, pull the first straight rod 4 through the handle. The movement of the first straight rod 4 drives the movement of the circular rubber plate 9, so that the air inside the outer shell 1 can be pumped out, making the inside of the outer shell 1 in a vacuum state. Thus, the device can be firmly fixed on the skin surface of the livestock, avoiding the livestock getting agitated and shaking due to the pain of blood collection during the blood collection process, which may cause damage to the livestock by the needle. At the same time, when the circular rubber plate 9 moves upward, it will contact the second straight rod 15 and exert a squeezing force on the second straight rod 15 to push the second straight rod 15 upward. The upward movement of the second straight rod 15 will contact the rotating plate 13 and push the rotating plate 13 to rotate counterclockwise. The rotation of the rotating plate 13 will contact the semi-circular plate 14 and exert a squeezing force on the semi-circular plate 14, causing the semi-circular plate 14 to move downward. The downward movement of the semi-circular plate 14 will push the syringe 10 downward, so that the livestock can be automatically pricked, enabling precise control of the pricking depth, angle, and position, reducing the situation of blood collection failure or improper blood collection site caused by human operation errors. After the pricking is completed, pull the pull handle 3. The movement of the pull handle 3 drives the movement of the L-shaped plate 11. The movement of the L-shaped plate 11 will drive the blood extraction handle of the syringe 10 to move, and then the blood of the livestock can be collected.

[0017] When performing vacuum pumping and fixing, the straight rod 4 drives the inclined strip plate 1610 to move upward. When the inclined strip plate 1610 moves upward, it will contact the first inclined block 163 and exert a squeezing force on the first inclined block 163, forcing the first inclined block 163 to move forward. The forward movement of the first inclined block 163 drives the movement of the first sliding rod 162, and the movement of the first sliding rod 162 will cause the spring to stretch. After the first inclined block 163 moves, the inclined strip plate 1610 continues to move until it reaches the top of the first inclined block 163. At this time, after the first inclined block 163 no longer contacts the inclined strip plate 1610, the spring resets and drives the first sliding rod 162 to move backward. The movement of the first sliding rod 162 drives the movement of the first inclined block 163. At this time, the inclined strip plate 1610 is above the first inclined block 163, so that the circular rubber plate 9 cannot move downward, and the position of the circular rubber plate 9 can be fixed, avoiding the situation that the circular rubber plate 9 is pulled downward and reset by the vacuum negative pressure generated by pumping, which may cause instability during blood collection. At the same time, when the circular rubber plate 9 moves, the circular rubber plate 9 will contact the inclined plate 164 and contact the inclined surface of the inclined plate 164, thereby pushing the inclined plate 164 to move forward. The forward movement of the inclined plate 164 will contact the second inclined block 167 and exert a squeezing force on the second inclined block 167, forcing the second inclined block 167 to move downward. The downward movement of the second inclined block 167 drives the movement of the second sliding rod 166, and the movement of the second sliding rod 166 drives the movement of the pressing plate 168, so that the iodophor stored in the disinfection box 165 can be sprayed onto the skin surface of the needle insertion through the liquid spraying pipe 169, reducing the link of manual spraying of iodophor and improving the efficiency of blood collection work. When the blood collection is completed, pull the pull rod provided on the surface of the first sliding rod 162 to release the limit on the circular rubber plate 9.

[0018] Please refer to Figures 1 - 9, on the basis of the above embodiments, in another embodiment of the present invention, the coating device 17 includes a straight plate 171, the straight plate 171 is fixedly connected to the inner wall of the inclined plate 164, an elastic telescopic plate 172 is fixedly connected to the inner wall of the straight plate 171, a scraping plate 173 is fixedly connected to the telescopic end of the elastic telescopic plate 172, a fixing rod 174 is fixedly connected to the inner wall of the inner barrel 6, and a second support plate 175 is fixedly connected to the right side of the elastic telescopic plate 172. When spraying iodophor, the movement of the inclined plate 164 drives the movement of the straight plate 171, the movement of the straight plate 171 drives the movement of the elastic telescopic plate 172, and the movement of the elastic telescopic plate 172 drives the movement of the second support plate 175 to improve the stability between the elastic telescopic plate 172 and the straight plate 171. The movement of the elastic telescopic plate 172 drives the movement of the scraping plate 173, so that the sprayed iodophor can be automatically smeared, enabling the iodophor to come into contact with the skin of the blood collection site more fully, deeply removing dirt, grease and microorganisms on the skin surface, further reducing the complexity of the worker's operation and improving the worker's work efficiency. A sliding block 176 is fixedly connected to the circumferential surface of the first sliding rod 162, an exhaust plug 177 is fixedly connected to the inner wall of the sliding block 176, the bottom of the straight plate 171 is in contact with the top of the second support plate 175, the inner wall of the fixed end of the elastic telescopic plate 172 is slidably connected to the fixing rod 174, the rear part of the sliding block 176 is in contact with the circumferential surface of the inner barrel 6, and the circumferential surface of the exhaust plug 177 is in contact with the inner wall of the outer shell 1. At the same time, when it is necessary to release the fixation of the device after blood collection is completed, the first sliding rod 162 needs to be completely pulled out. The movement of the first sliding rod 162 drives the movement of the sliding block 176, and the movement of the sliding block 176 drives the movement of the exhaust plug 177. After the first sliding rod 162 is completely pulled out, the notch of the exhaust plug 177 will be in contact with the outside, so that the outside air flows into the inside of the outer shell 1, making the air pressure inside the outer shell 1 communicate with the outside, and thus the device can be detached.

[0019] Working principle: When spraying iodophor, the inclined plate 164 moves to drive the straight plate 171 to move. The movement of the straight plate 171 drives the elastic telescopic plate 172 to move. The movement of the elastic telescopic plate 172 drives the second support plate 175 to move, so as to improve the stability between the elastic telescopic plate 172 and the straight plate 171. The movement of the elastic telescopic plate 172 drives the scraper 173 to move, so that the sprayed iodophor can be automatically smeared, enabling the iodophor to come into contact with the skin of the blood collection site more fully, deeply removing dirt, grease and microorganisms on the skin surface, further reducing the tediousness of the worker's operation, improving the worker's work efficiency. At the same time, when it is necessary to release the fixation of the device after blood collection is completed, the first sliding rod 162 needs to be completely pulled out. The movement of the first sliding rod 162 drives the sliding block 176 to move. The movement of the sliding block 176 drives the exhaust plug 177 to move. After the first sliding rod 162 is completely pulled out, the notch of the exhaust plug 177 will be in contact with the outside world, so that the outside air flows into the interior of the housing 1, making the air pressure inside the housing 1 communicate with the outside world, and then the device can be detached.
