Description

Technical Field

[0001] This utility model relates to the field of animal blood collection technology, and in particular to an auxiliary device for blood collection from cattle tails and a fully automatic blood collection system from cattle tails. Background Technology

[0002] In animal husbandry, the collection of animal blood samples is a crucial step in disease diagnosis, health monitoring, and genetic research. For cattle, the tail vein is one of the commonly used blood collection sites. However, due to the depth of the tail vein and the large size of cattle, manual blood collection requires restraint, further increasing the difficulty of the procedure. Traditional manual blood collection methods are not only inefficient but also carry certain risks, especially in large animals like cattle. Manual blood collection can cause significant stress to the animals, affecting their health and production performance, and may also lead to collection failure or sample contamination due to improper operation.

[0003] Currently, there are some auxiliary devices for ox tail blood collection on the market, but most of these devices still have some shortcomings. First, most existing devices are complex to operate, difficult to fix in the ox's tail, and require professional operation. Second, existing devices are mostly of a single size, often unable to adapt to cattle of different sizes, causing the animal to struggle during blood collection and affecting the blood collection effect. Third, because the ox's tail vein is located deep, existing blood collection needles often have difficulty accurately locating the vein, leading to blood collection failure or requiring multiple attempts, causing pain to the cattle. In addition, some automated blood collection devices are expensive to manufacture, which is not conducive to their widespread adoption in large-scale farming. Some blood collection devices also have requirements for blood collection tubes, only applicable to certain sizes of blood collection tubes, greatly limiting their applicability.

[0004] There are no effective solutions yet for the problems in the relevant technologies, such as the complex operation and unstable fixing of blood collection devices, the inability to adjust the blood collection devices according to the size of the cow's tail, and the limitation of the blood collection devices to only certain blood collection tubes.

[0282] How to use this utility model:

[0283] (a) Fixing the blood collection needle

[0284] The needle holder of the blood collection needle is placed in the third groove element 404. The fourth fixing element 405 is rotated, and the fourth rotating element 406 rotates relative to the third rotating element 402. The top of the needle holder of the blood collection needle enters the fourth groove element 408. The fourth fixing element 405 and the third fixing element 401 clamp the needle holder of the blood collection needle. The first locking element 403 and the second locking element 407 are used to lock the connection to fix the needle holder of the blood collection needle. Then, by operating the operating element 603, the central control element 601 starts the second power element 306 to drive the second lead screw element 307 to drive the second sliding element 308 to slide, which in turn drives the third sliding element 309 to drive the first fixing unit 400 into the first channel element 105.

[0285] (ii) Fixing the blood collection tube

[0286] The third power element 503 is activated by the central control element 601 through the operating element 603 to drive the third lead screw element 504 to rotate, thereby causing the sixth sliding element 505 and the fifth fixing element 506 to move relative to the third lead screw element 504, exposing the fifth fixing element 506; the fifth fixing element 506 is used to clamp the tube body of the blood collection tube, and the fourth limiting element 508 is used to fix the tube cap end of the blood collection tube, so that the tube cap end is located at the fourth limiting element 508, and the sealing element 509 is fixed to the fourth limiting element 508, thereby fixing the tube cap end of the blood collection tube, and the connection height between the sealing element 509 and the fourth limiting element 508 can be adjusted according to the specifications of the blood collection tube.

[0287] (iii) Clamped in the cow's tail

[0288] Pressing the first pressing element 102 and the second pressing element 202 causes the first rotating element 103 and the second rotating element 203 to rotate relative to each other, opening the first fixing element 101 and the second fixing element 201 and clamping the first fixing element 101 and the second fixing element 201 onto the cow's tail. The first groove element 106 and the second groove element 204 adjust the radial dimension of the closed loop formed by the first fixing element 101 and the second fixing element 201 according to the size of the cow's tail, so that the first fixing element 101 and the second fixing element 201 are fixed to the cow's tail.

[0289] (iv) Blood collection

[0290] The first power element 301 is activated by the central control element 601 via the operating element 603 to drive the first lead screw element 302 to rotate, thereby causing the first sliding element 303 to slide along the first lead screw element 302, so that the first sliding element 303 is located at the blood collection site; the second power element 306 drives the second lead screw element 307 to rotate, thereby causing the second sliding element 308 to slide along the second lead screw element 307, and causing the third sliding element 309 to move towards the cow's tail blood collection site until the blood collection needle pierces the cow's tail and stops moving. The blood collection needle collects blood from the cow's tail. The staff inserts the other end of the blood collection needle into the blood collection tube. When the blood collection volume meets the requirements, the blood collection is stopped by the operating element 603. The second power element 306 drives the second sliding element 308 and the third sliding element 309 to move the blood collection needle away from the cow's tail and into the channel element 105.

[0291] (iv) Disassembly

[0292] The first cow tail fixing unit 100, the second cow tail fixing unit 200, the blood collection needle and the blood collection tube were removed by means of clamping the cow tail and fixing the blood collection needle and the blood collection tube. The blood collection needle was disposed of in accordance with the medical waste disposal requirements and the blood collection tube was preserved.

[0293] The technical effects of this utility model are as follows:

[0294] The device uses a first and second cow tail fixing unit to clamp the cow tail, and the radial dimension can be adjusted according to the size of the cow tail, reducing pressure on the cow tail. It is simple to operate and firmly fixed, solving the problems of complex operation and unstable fixation of blood collection devices, and the inability of blood collection devices to be adjusted according to the size of cow tails. The position adjustment unit can adjust the lateral and longitudinal positions of the first fixing unit to collect blood from the cow tail. The second fixing unit can fix blood collection tubes of different specifications, solving the problem that the blood collection device is only applicable to a certain type of blood collection tube and has limited use.

[0295] Example 2

[0296] This embodiment is a modified embodiment of embodiment 1.

[0297] like Figure 8 As shown, the ox tail blood collection auxiliary device also includes an elastic unit 700. The elastic unit 700 is rotatably connected to the first ox tail fixing unit 100 and the second ox tail fixing unit 200, respectively, and is used to open or close the connection between the second side of the first ox tail fixing unit 100 and the second side of the second ox tail fixing unit 200.

[0298] like Figure 9As shown, the elastic unit 700 includes a fifth rotating element 701 and an elastic element 702. The fifth rotating element 701 is rotatably connected to the first cow tail fixing unit 100 and the second cow tail fixing unit 200, respectively. The elastic element 702 is sleeved on the fifth rotating element 701, and its two ends are connected to the sides of the first cow tail fixing unit 100 and the second cow tail fixing unit 200, respectively, for opening or closing the connection between the first cow tail fixing unit 100 and the second cow tail fixing unit 200.

[0303] In some of these embodiments, the elastic element 702 is a return spring or a return torsion spring.

[0304] The usage method of this embodiment is as follows:

[0305] The difference between this embodiment and Embodiment 1 is that when the first fixing element 101 and the second fixing element 201 are clamped in the cow's tail, pressing the first pressing element 102 and the second pressing element 202 causes the first rotating element 103 and the second rotating element 203 to rotate relative to the fifth rotating element 701. The elastic element 702 deforms, and the first fixing element 101 and the second fixing element 201 open and clamp in the cow's tail. The first groove element 106 and the second groove element 204 adjust the radial dimension of the closed loop formed by the first fixing element 101 and the second fixing element 201 according to the size of the cow's tail. The elastic element 702 restores its deformation, thus fixing the temperature of the first fixing element 101 and the second fixing element 201 in the cow's tail.

[0306] Other usage methods are the same as in Example 1.

[0307] The technical effects of this embodiment are as follows:

[0308] The elastic unit can be used to stabilize the first cow tail fixing unit and the second cow tail fixing unit on the cow tail, making the fixation more secure.

[0316] In some embodiments, the support element 801 includes a base and a support rod. The base is connected to the first fixing element 101 (the second fixing element 201); the support rod is disposed on the side of the base and connected to the sixth fixing element 802.

[0317] The sixth fixing element 802 is connected to the support element 801 by a fixed connection. The fixed connection method includes, but is not limited to, integral molding.

[0318] The dimensions of the sixth fixing element 802 are matched with the dimensions of the support element 801. Generally, the radial dimension (e.g., outer diameter) of the sixth fixing element 802 is not smaller than the radial dimension (e.g., outer diameter) of the support element 801.

[0319] In some of these embodiments, the sixth fixing element 802 is a fixing base.

[0320] The dimensions of the third placement element 803 are matched with the dimensions of the sixth fixing element 802. Generally, the radial dimension (e.g., outer diameter) of the third placement element 803 is smaller than the radial dimension (e.g., outer diameter) of the sixth fixing element 802, and the height of the third placement element 803 is smaller than the height of the sixth fixing element 802.

[0321] In some of these embodiments, the third placement element 803 is a third clamping groove.

[0322] The dimensions of the fifth limiting element 804 are matched with the dimensions of the sixth fixing element 802. Generally, the radial dimension (e.g., outer diameter) of the fifth limiting element 804 is smaller than the radial dimension (e.g., outer diameter) of the sixth fixing element 802, and the height of the fifth limiting element 804 is smaller than the height of the sixth fixing element 802.

[0323] The dimensions of the fifth limiting element 804 are matched with the dimensions of the third placement element 803. Generally, the radial dimension (e.g., outer diameter) of the fifth limiting element 804 is larger than the radial dimension (e.g., outer diameter) of the third placement element 803.
