Description

Technical Field

[0001] The invention belongs to the technical field of blood sampling for prevention and control, and in particular relates to a blood sampling device for animal disease prevention and control. Background Art

[0002] Animal diseases have an important impact on the breeding industry and public health. In order to effectively control the spread and epidemic of animal diseases, animal disease prevention and control centers at all levels need to conduct regular disease monitoring and testing of livestock and poultry within their jurisdiction. This includes monitoring the prevention of major animal diseases such as foot-and-mouth disease, swine fever, and avian influenza, to ensure animal health, prevent diseases from causing significant losses to the breeding industry, and protect humans from potential public health risks.

[0003] In the work of animal disease prevention and control, blood testing is a vital task. By collecting blood samples from animals, various components in the blood can be analyzed to understand the health status of the animals. During the blood drawing process, the negative pressure principle in the blood collecting tube is the key to the smooth entry of blood into the tube. However, if the negative pressure in the blood collecting tube is too large, the blood will flow into the tube quickly, causing hemolysis, which will affect the subsequent laboratory test results. On the contrary, if the negative pressure is too small, the speed at which blood flows into the tube will slow down, and the blood may even not flow into the tube smoothly. Therefore, the negative pressure and capacity in the blood collecting tube are certain. In the blood collection process of some large animals, in order to analyze and back up the blood samples more comprehensively, staff are often required to insert the blood collecting needle into multiple blood collecting tubes during the blood drawing process to ensure that the collected blood samples reach a sufficient amount. This undoubtedly increases the workload of the staff during the blood drawing process and prolongs the time of the blood drawing process. Summary of the invention

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-6 The present invention provides a technical solution: a blood sampling device for animal disease prevention and control, comprising a limit plate 1, the front of the limit plate 1 is slidably connected to two limit cylinders 4, the interior of the limit plate 1 is provided with two second through grooves 17, the inner walls of the two second through grooves 17 are slidably connected to a pair of piston rods 18, the ends of the pair of piston rods 18 that are away from each other are fixedly connected to the outer surface of the limit cylinder 4, and the telescopic springs 19 arranged in the two second through grooves 17 are fixedly connected to the outer surface of the piston rod 18, the telescopic spring 19 is also called spring telescopic or elastic telescopic, which is a mechanical component that works based on the elastic principle, which can be deformed when subjected to external force and return to its original state after the external force disappears, and this component is usually made of elastic materials such as spring steel, and has the characteristics of simple structure, safety, reliability, long service life, etc. Figure 5The middle telescopic spring 19 is in a natural state. The coordination between the second through groove 17, the piston rod 18 and the telescopic spring 19 is conducive to driving the two limit cylinders 4 to approach each other, so that the two limit cylinders 4 can clamp the blood drawing hose 9 in front of the limit plate 1, and it is also more convenient for the blood drawing hose 9 to be separated from the limit of the device. The output ends of the motor 8 fixedly connected to the back of the two limit cylinders 4 extend to the inside of the limit cylinder 4 and are fixedly connected to the cross rotating plate 2. The two motors 8 rotate in opposite directions, so that the output ends of the two motors 8 can drive the extrusion wheel 3 to squeeze the outer surface of the blood drawing hose 9, thereby driving the blood inside the blood drawing hose 9 from one end to the other end. The motor 8 does not contact the penetration of the limit cylinder 4 to prevent the motor 8 from generating friction with the penetration of the limit cylinder 4 when working. The inner walls of the two cross rotating plates 2 are rotatably connected with a group of extrusion wheels 3, and a group of extrusion wheels 3 are in a ring array. The side surface of the two limit cylinders 4 that is close to each other is provided with a first through groove 5 adapted to the cross rotating plate 2 and the extrusion wheel 3. The extrusion wheel 3 penetrates the first through groove 5 and is slidably connected to the outer surface of the blood drawing hose 9.

[0032] The outer surface of the limiting cylinder 4 is provided with a mobile power supply which is electrically connected to the motor 8. One end of the blood drawing hose 9 is fixedly connected to the needle, and the other end is fixedly connected to the blood collecting needle. The two limiting cylinders 4 are moved in opposite directions so that the blood drawing hose 9 is located in front of the limiting plate 1, and the blood drawing hose 9 is located between the two pairs of arc-shaped clamping rings 10. During the process, the telescopic spring 19 changes from a natural state to a stretched state, and subsequently the telescopic spring 19 changes from a stretched state to a natural state, so that the two limiting cylinders 4 are close to each other, and the two arc-shaped clamping rings 10 clamp the blood drawing hose 9. The extrusion wheel 3 contacts the outer surface of the blood drawing hose 9, and one end of the moving clamping plate 6 clamps the clamping plate 6 with the outer surface of the clamping block 7. During the process, the limiting ball 14 clamps with the inner wall of the limiting groove 16, so as to limit the two limiting cylinders 4 and advance the blood drawing. After the work is ready, the needle is inserted into the animal's blood vessel, and the blood collecting needle is connected to the blood collecting tube. When the motor 8 drives the cross-turn plate 2 and the extrusion wheel 3 to rotate, the rolling and squeezing of the extrusion wheel 3 on the outer surface of the blood drawing hose 9 is conducive to the continuous flow of blood from one end to the other end inside the blood drawing hose 9, so that the flow of blood is not affected by the negative pressure in the blood collecting tube or the blood collecting bag. After the blood collecting needle is inserted into the blood collecting tube, the blood drawing amount can be completed at one time. The device can be prepared before blood drawing, and the blood collecting tube can be replaced during the blood drawing process without being affected by the negative pressure inside the blood collecting tube, thereby reducing the workload of the staff during the blood drawing process and shortening the duration of the blood drawing process. The device is small and portable, and the blood drawing hose 9 connected inside the device is easy to replace, which prevents blood sample contamination caused by blood drawing from different animal individuals and can be reused.

[0033] The outer surfaces of the cross-turn plate 2 and the extrusion wheel 3 are not in contact with the inner walls of the limiting cylinder 4 and the first through groove 5, so as to prevent the motor 8 from driving the cross-turn plate 2 and the extrusion wheel 3 to rotate and generate friction with the inner walls of the limiting cylinder 4 and the first through groove 5. The two limiting cylinders 4 are adapted to the blood drawing hose 9 arranged in front of the motor 8. The extrusion wheels 3 close to each other in the two groups are in contact with the outer surface of the blood drawing hose 9. The upper and lower ends of the two limiting cylinders 4 are fixedly connected with symmetrical arc-shaped clamping rings 10. Each arc-shaped clamping ring 10 has a The inner walls are inlaid with arc-shaped rubber rings 11, which are clamped with the outer surface of the blood drawing hose 9. The ring formed by the left and right arc-shaped rubber rings 11 and the arc-shaped clamping ring 10 is adapted to the blood drawing hose 9. The outer surface of the blood drawing hose 9 is limited by the coordinated setting of the arc-shaped clamping ring 10 and the arc-shaped rubber ring 11. The clamping plate 6 hinged on the outer surface of one limiting cylinder 4 is clamped with the clamping block 7 set on the outer surface of the other limiting cylinder 4, and the clamping block 7 is fixedly connected to the outer surface of the limiting cylinder 4.

[0034] A pair of circular grooves 12 are provided on the back of the clamping plate 6. Compression springs 13 arranged on the inner walls of the two circular grooves 12 are fixedly connected to the limiting balls 14 which are slidably connected inside the circular grooves 12. A limiting groove 16 adapted to the limiting ball 14 is provided on the front of the right limiting cylinder 4. When the limiting ball 14 is engaged with the inner wall of the limiting groove 16, the compression spring 13 is in a natural state. The end of the compression spring 13 away from the limiting ball 14 is fixedly connected to the inner wall of the circular groove 12. Figure 4 The compression spring 13 is in a natural state, and the compression spring 13 provides a reset function for the limiting ball 14. The matching arrangement of the compression spring 13, the limiting ball 14 and the limiting groove 16 provides a limiting effect for the card plate 6. The front of the card plate 6 is inlaid with a rubber layer 15. The rubber layer 15 generally refers to a layer structure composed of rubber material, which is widely used in various products and equipment, and provides elasticity, sealing, wear resistance, corrosion resistance and other functions. The setting of the rubber layer 15 increases the friction on the front of the card plate 6, which facilitates the movement of the card plate 6.

[0035] A bottom plate 20 is arranged on the back of the limiting plate 1, and a square groove 21 and two card grooves 22 are opened on the front of the bottom plate 20. A group of suction cups 23 are fixedly connected to the back of the bottom plate 20, and an air-tight cavity is arranged inside the suction cups 23. When the suction cups 23 are in contact with the surface of the object, a sealed space is formed between the rubber material and the surface of the object. When the entrance of the suction cups 23 separated from the external environment is closed, air is extracted from the cavity isolated from the outside world to form a negative pressure area. When the negative pressure adsorption force is greater than the contact force between the object and the surface, the object will be tightly adsorbed. Attached to the suction cup 23, this is because the negative pressure on the surface of the suction cup 23 will produce a vacuum effect, which firmly fixes the object on the suction cup 23. The square groove 21 is adapted to the limiting plate 1, so that the limiting plate 1 is conveniently connected to the inside of the square groove 21. The card slot 22 is adapted to the motor 8, so that the motor 8 is conveniently connected to the inside of the card slot 22. The inner wall of the card slot 22 is inlaid with an annular magnet 24. The magnet is a kind of magnet that can attract metals. Its main components include atoms such as iron, cobalt, and nickel. The internal structure of these atoms is special and has magnetic moment itself. The outer surface of the motor 8 is fixedly connected A protective metal ring 25 adapted to the annular magnet 24 is connected, the outer ring of the protective metal ring 25 is made of iron, the inner ring is made of aluminum alloy, the inner wall of the aluminum alloy is fixedly connected to the motor 8, the iron material of the outer ring can be adsorbed with the annular magnet 24, the annular magnet 24 can be adsorbed on the outer surface of the protective metal ring 25, the alloy material can effectively shield the external magnetic field, and its application is mainly concentrated in the field of electronic equipment and communications. The setting of the protective metal ring 25 plays a certain role in preventing interference with the operation of the motor 8, thereby reducing the influence of the annular magnet 24 on the motor 8, and preventing The coordinated arrangement of the protective metal ring 25 and the annular magnet 24 is conducive to the clamping connection between the motor 8 and the inner wall of the slot 22. A through hole 26 is provided on the inner wall of the slot 22. The opening of the through hole 26 is conducive to the heat dissipation of the motor 8. The base plate 20 is adsorbed on a platform such as a desktop through the suction cup 23. After the blood drawing hose 9 is clamped, the two limiting cylinders 4 are placed on the outer surface of the base plate 20, so that the motor 8 is clamped inside the slot 22, and the limiting plate 1 is clamped inside the square groove 21, thereby limiting the device parallel to a platform such as a desktop, reducing the influence of the device's own gravity on the blood drawing hose 9.

[0036] Working principle: When in use, the motor 8 is connected to the mobile power supply, and the two limiting cylinders 4 are moved in opposite directions, so that the blood drawing hose 9 is located in front of the limiting plate 1, and the blood drawing hose 9 is located between the two pairs of arc-shaped clamping rings 10. During the process, the telescopic spring 19 changes from a natural state to a stretched state, and subsequently the telescopic spring 19 changes from a stretched state to a natural state, so that the two limiting cylinders 4 are close to each other, and the two arc-shaped clamping rings 10 clamp the blood drawing hose 9, and the extrusion wheel 3 is connected to the outer surface of the blood drawing hose 9. One end of the moving clamping plate 6 makes the clamping plate 6 clamped with the outer surface of the clamping block 7, and during the process, the limiting ball 14 is connected to the inner surface of the limiting groove 16. The walls are clamped to limit the two limiting cylinders 4. When the motor 8 drives the cross-turn plate 2 and the extrusion wheel 3 to rotate, the rolling and squeezing of the extrusion wheel 3 on the outer surface of the blood drawing hose 9 is beneficial to the continuous flow of blood inside the blood drawing hose 9 from one end to the other. The device can be prepared before blood drawing, and the blood collecting tube can be replaced during the blood drawing process without being affected by the negative pressure inside the blood collecting tube, thereby reducing the workload of the staff during the blood drawing process and shortening the duration of the blood drawing process. The device is small and portable, and the blood drawing hose 9 clamped inside the device is easy to replace, which prevents blood sample contamination caused by blood drawing from different animal individuals and can be reused.
