Technical Field
[0001] The utility model relates to a device for collecting blood from the anterior vena cava during pig feeding, belonging to the technical field of venous blood collecting devices for pigs. Background Art
[0002] In pig production, blood samples must be collected from pigs for both diagnosis and treatment of pig diseases and antibody testing. Commonly used blood collection sites include the pig's anterior vena cava, jugular vein and ear vein. The pig's anterior vena cava blood collection operation is fast and suitable for blood collection from piglets to breeding pigs. It can also collect high-quality blood samples. Blood samples can be used to monitor the antibody levels of pigs in pig farms to improve the accuracy of detection.
[0003] There are still some problems in the use of the existing venous blood sampling device for pigs. If venous blood is directly collected from pigs, the pigs will strongly resist. Therefore, blood is usually collected from the pigs while they are eating, and the blood sampling device is not operated manually. Therefore, the pigs need to be comforted at the same time, which makes the operation more troublesome. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] Example 1 Please refer to Figure 1-Figure 4 , the utility model provides a technical solution:
[0024] A device for collecting blood from the anterior vena cava during feeding of live pigs, comprising a fence frame 1, a door panel 2 is rotatably connected to the outer side of the fence frame 1, an electric telescopic rod 3 is fixedly installed on the outer side of the fence frame 1, a push rod 4 is fixedly connected to the outer side of the electric telescopic rod 3, a moving plate 5 is fixedly connected to the outer side of the push rod 4, a buffer spring 6 is fixedly connected to the outer side of the moving plate 5, a clamping plate 7 is fixedly connected to the outer side of the buffer spring 6, a lifting groove 8 is opened in the inner wall of the fence frame 1, a sliding rod 9 is slidably connected to the inside of the lifting groove 8, a food trough 10 is fixedly connected to the outer side of the sliding rod 9, a sliding block 11 is fixedly connected to the end of the sliding rod 9 away from the food trough 10, a stabilizing plate 12 is fixedly connected to the outer side of the fence frame 1, a fixing plate 13 is fixedly connected to the top of the stabilizing plate 12, a motor 14 is fixedly installed on the outer side of the stabilizing plate 13, a retracting rod 15 is fixedly connected to the output end of the motor 14, and a nylon rope 16 is wound around the outer side of the retracting rod 15.
[0025] Specifically, Figure 1 As shown, the electric telescopic rod 3 is symmetrically distributed on the outside of the fence frame 1, the pushing rod 4 crosses the inside of the fence frame 1, the movable plate 5 and the clamping plate 7 are symmetrically distributed inside the fence frame 1, the food trough 10 is installed on the inner wall of the fence frame 1 through the sliding rod 9, the retracting rod 15 is rotatably connected between the two fixed plates 12, and the bottom of the nylon rope 16 is fixedly connected to the top of the sliding block 11.
[0026] Furthermore, by driving the push rod 4 to move through the electric telescopic rod 3, the movable plate 5 outside the push rod 4 can be moved to any position inside the fence frame 1, so that pigs of different sizes can be clamped and processed, and a groove is opened inside the feeding trough 10, and the groove can clamp the pig's neck by moving the feeding trough 10 upward.
[0027] In this embodiment, a fence frame 1 is provided, and the door panel 2 is first opened to drive the pigs into the fence frame 1. At this time, the electric telescopic rod 3 is started to drive the push rod 4 to move. Since a moving plate 5 is fixedly connected to the outside of the push rod 4, the moving plate 5 is used in conjunction with the buffer spring 6, so that the clamping plate 7 clamps both sides of the pigs, and can clamp pigs of different sizes. When the clamping is completed, the pigs eat in the feed trough 10. At this time, By starting the motor 14, the motor 14 drives the folding rod 15 to rotate. Since a nylon rope 16 is wrapped around the outside of the folding rod 15, and the bottom of the nylon rope 16 is fixedly connected to the top of the sliding block 11, the nylon rope 16 will drive the sliding block 11 to move on the outside of the fence frame 1, so that the sliding block 11 drives the feeding trough 10 on the outside of the sliding rod 9 to move on the inner wall of the fence frame 1. When the feeding trough 10 moves upward, it can clamp the neck of the pig, thereby facilitating the subsequent blood collection process.
[0028] Example 2 Please refer to Figure 1 , Figure 2 and Figure 4 The difference between this embodiment and embodiment 1 is that: a collecting box 17 is fixedly connected to the outside of the fence frame 1, a scale 18 is fixedly connected to the outside of the collecting box 17, a catheter 19 is fixedly connected to the outside of the collecting box 17, an extraction pump 20 is fixedly connected to the outside of the catheter 19, a telescopic hose 21 is fixedly connected to the outside of the extraction pump 20, a needle 22 is fixedly connected to the outside of the telescopic hose 21, and a liquid outlet pipe 23 is fixedly connected to the outside of the collecting box 17.
[0029] Specifically, Figure 1-4 As shown, the catheter 19 crosses the interior of the fence frame 1, the extraction pump 20 is fixedly connected to the inner wall of the fence frame 1, the telescopic hose 21 and the needle 22 are located inside the fence frame 1, and one end of the liquid outlet tube 23 is fixedly connected to the inside of the collection box 17.
[0030] Furthermore, the characteristics of the telescopic hose 21 itself can enable the needle 22 to move inside the fence frame 1, so that the needle 22 is inserted into the neck of the pig, and by controlling the start and stop of the extraction pump 20, the amount of blood drawn can be controlled. Moreover, since a scale 18 is fixedly connected to the outside of the collection box 17, the extraction amount can be accurately seen.
[0031] In the present embodiment: by setting up a feeding trough 10, when the feeding trough 10 clamps the neck of the pig, the needle 22 is moved by the telescopic hose 21, so that the needle 22 is inserted into the neck of the pig. At this time, by starting the extraction pump 20, blood is collected from the pig, and the collected blood will enter the interior of the collection box 17 through the catheter 19. When the blood collection is completed, the collected blood can be collected through the liquid outlet tube 23, thereby achieving the effect of convenient blood collection.
[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
