Description

Technical Field

[0001] The utility model relates to the technical field of animal husbandry, in particular to a blood sampling device for animal husbandry and veterinary medicine. Background Art

[0002] With the development of animal husbandry and the progress of society, the public has adopted more scientific livestock breeding methods, such as life and health testing of livestock, regular blood tests of livestock, checking of vital signs of livestock, monitoring of livestock disease prevention, and ensuring a clean breeding environment.

[0003] When collecting blood from large animals, if the needle is inserted too shallowly, blood cannot be drawn effectively. When drawing blood from small animals, if the needle is inserted too deeply, it is very easy to pierce and damage internal organs, causing harm to the animal and hindering the blood drawing work.

[0004] For example, the "A blood collection device for livestock and veterinary medicine" with the authorization announcement number "CN220089486U" is equipped with a movable ring connected to the outside of the syringe with a thread. The movable ring is rotated to move up or down, thereby driving the connecting rod, vertical rod, and abutment plate to move, and then adjusting the distance that the blood collection needle extends out of the abutment plate, making it convenient for the veterinarian to control the insertion depth of the needle.

[0005] Although the above scheme can control the depth of the needle inserted into the animal's body, it cannot control the amount of blood collected from the animal. During the use of the livestock and veterinary blood collection device, since the syringe is not provided with a quantitative structure and the animal is restless during the blood collection state, it is difficult to always observe the scale on the surface of the syringe, resulting in the difficulty in controlling the amount of blood collected, which is not conducive to livestock blood testing. Summary of the invention

[0006] The purpose of the utility model is to provide a blood sampling device for livestock and veterinary medicine, which can control the distance between the bottom of the piston and the bottom of the cylinder. The capacity formed between the bottom of the piston and the cylinder is the amount of blood drawn each time. In this way, the amount of blood drawn each time can be accurately controlled to avoid drawing too much or too little blood, so as to solve the problems raised in the above-mentioned background technology.

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.

[0026] See also Figures 1 to 3 The utility model provides a technical solution: a blood sampling device for animal husbandry and veterinary medicine, comprising a cylinder 1, a connecting rod 2 is slidably connected to the top of the cylinder 1, a pressing platform 3 is fixedly connected to the top of the connecting rod 2, a connecting head 4 is fixedly inserted at the bottom of the cylinder 1, a needle 5 is clamped at the bottom of the connecting head 4, a piston 6 is fixedly connected to the bottom of the connecting rod 2, the outer wall of the piston 6 is in contact with the inner wall of the cylinder 1, a first spring 9 is fixedly connected between the piston 6 and the top inner wall of the cylinder 1, a quantitative mechanism 7 is arranged on the top of the cylinder 1, the quantitative mechanism 7 is used to control the amount of blood collected, the quantitative mechanism 7 comprises two connecting frames 71 slidably connected to the top of the cylinder 1, the front sides of the two connecting frames 71 are fixedly connected to limiting blocks 72, the two limiting blocks 72 are respectively Located on both sides of the connecting rod 2, the quantitative mechanism 7 also includes a fixed block 73 fixedly connected to the top of the cylinder 1, and the left side of the fixed block 73 is rotatably connected to a bidirectional screw rod 74, and the outer walls of the bidirectional screw rod 74 are respectively threadedly connected to the two connecting frames 71 on both sides, and the two sides of the connecting rod 2 are inclined, and the side of the limiting block 72 close to the connecting rod 2 is also inclined. A groove 75 is provided on the top of the side where the two limiting blocks 72 are close to each other, and the inside of the two grooves 75 are slidably connected with an insert block 76, and a card slot 77 is provided on the top of the connecting rod 2. A second spring 78 is fixedly connected between the insert block 76 and the limiting block 72, and a pull rod 79 is fixedly connected to the side where the two insert blocks 76 are away from each other, and the outer walls of the two pull rods 79 are slidably connected to the limiting block 72.

[0027] By adopting the above technical solution, the detachable connection method of the needle 5 can be but is not limited to a snap-on connection. When it is necessary to draw blood from an animal, the pressing platform 3 is first pressed by hand so that the bottom of the piston 6 is close to the bottom of the cylinder 1. A round block adapted to a flat-blade screwdriver is fixed to the left side of the two-way screw rod 74. By inserting an external screwdriver into the flat-blade hole of the round block, the two-way screw rod 74 can be rotated to move the connecting frame 71 with the limiting block 72 until the inclined part of the limiting block 72 fits the inclined parts on both sides of the connecting rod 2. Due to the inclination of both sides of the connecting rod 2, the connecting rod 2 gradually widens from top to bottom. When the inclined part of the limiting block 72 fits the inclined parts on both sides of the connecting rod 2, the piston 6 can be prevented from moving upward due to the elastic force of the first spring 9. At this time, the round block is slowly rotated in the other direction by an external flat-blade screwdriver, and the two-way screw rod 74 is slowly rotated in the other direction, so that the two limiting blocks 72 move away from each other, thereby The piston 6 moves upward slowly, and the cylinder 1 can be made of transparent plastic material, and its outer wall is provided with scales. The piston 6 is moved to a suitable position according to the scales. At this time, the capacity formed between the bottom of the piston 6 and the cylinder 1 is the amount of blood drawn each time, so that the amount of blood drawn each time can be accurately controlled to avoid excessive or insufficient blood drawing. When preparing for blood drawing, the pressing platform 3 is pressed by hand so that the bottom of the piston 6 fits the bottom of the cylinder 1. At this time, the insert block 76 is just aligned with the slot 77. Under the elastic force of the second spring 78, the insert block 76 is inserted into the slot 77, thereby limiting the piston 6 and the connecting rod 2. At this time, the needle 5 can be inserted into the animal's body, and the pull rod 79 is pulled away from the insert block 76. Under the elastic force of the first spring 9, the piston 6 and the connecting rod 2 move upward until the inclined part of the connecting rod 2 is limited by the limiting block 72. In this way, negative pressure is generated at the bottom of the piston 6, and blood drawing can be completed for the animal.

[0028] Specifically, Figure 1 , Figure 2 and Figure 4 As shown, a depth limiting mechanism 8 is provided at the bottom of the cylinder 1, and the depth limiting mechanism 8 is used to control the insertion depth of the needle 5. The depth limiting mechanism 8 includes ear plates 81 fixedly connected to the bottom of both sides of the cylinder 1, and a slide 82 is slidably connected inside the ear plate 81. The bottom of the slide 82 is fixedly connected to a support plate 83, and a through groove 84 is provided in the middle part of the support plate 83. The bottom of the outer wall of the slide 82 on the left side is provided with a thread, and a thread block 85 is threadedly connected at the threaded portion. The top of the thread block 85 is rotatably connected to a swivel 86, and a measuring plate 87 is fixedly connected to the left side of the swivel 86. The left side of the support plate 83 is fixedly connected to a mounting plate 88, and the left side of the measuring plate 87 is slidably connected to the mounting plate 88.

[0029] By adopting the above technical solution, when drawing blood, first slide the support plate 83 to the point where the distance from the bottom of the cylinder 1 is the largest, then fit the support plate 83 to the skin of the animal, press the cylinder 1, and insert the needle 5 into the skin of the animal. In the preparation stage, the threaded block 85 can be rotated by an external wrench to control the distance between the top of the swivel 86 and the ear plate 81. When the cylinder 1 is pressed to insert the needle 5 into the skin of the animal, when the bottom of the ear plate 81 contacts the top of the swivel 86, the needle 5 cannot be inserted further. In this way, the insertion depth of the needle 5 can be controlled by rotating the threaded block 85, and a scale can be set on the right side of the mounting plate 88. When the threaded block 85 is rotated to make the threaded block 85 and the swivel 86 move up and down, the measuring plate 87 moves up and down accordingly. By comparing the position of the measuring plate 87 with the scale, the insertion depth of the needle 5 can be obtained, thereby controlling the insertion depth of the needle 5.

[0030] Working principle: By rotating the bidirectional screw rod 74, the two limiting blocks 72 can be controlled to move, so that the distance between the bottom of the piston 6 and the bottom of the cylinder 1 can be controlled. The capacity formed between the bottom of the piston 6 and the cylinder 1 is the amount of blood drawn each time, so that the amount of blood drawn each time can be accurately controlled to avoid excessive or insufficient blood drawing. When preparing for blood drawing, the pressing platform 3 is pressed by hand so that the bottom of the piston 6 fits the bottom of the cylinder 1. At this time, the insert block 76 is just aligned with the slot 77. Under the elastic force of the second spring 78, the insert block 76 is inserted into the slot 77, thereby limiting the piston 6 and the connecting rod 2. Then the support plate 83 is fitted to the skin of the animal, and the cylinder 1 is pressed so that the needle 5 is inserted into the skin of the animal. The pull rod 79 is pulled away from the insert block 76. Under the elastic force of the first spring 9, the piston 6 and the connecting rod 2 move upward until the inclined part of the connecting rod 2 is restricted by the limiting block 72. In this way, negative pressure is generated at the bottom of the piston 6, and blood drawing can be completed for the animal.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
