Description

A device for collecting defibrinated blood from cattle and sheep Technical Field

[0001] This utility model relates to the field of blood collection devices, and more specifically, to a device for collecting defibrinated blood from cattle and sheep. Background Technology

[0002] Blood agar plates, also known as blood agar plates or blood plates, are agar plates rich in animal blood components. They are commonly used in microbiology experiments to detect the reactions of different bacteria to blood components. The preparation of blood agar plates requires a large amount of defibrinated blood from healthy sheep or cows.

[0003] In the prior art, Chinese utility model patent CN222550937U discloses a bovine and ovine defibrinated blood collection device, which includes a glass bottle, a sealing cap, a vacuum interface, and glass beads placed inside the bottle. When using this device, one end of a rubber tube must be sealed to the vacuum interface, and the other end connected to a vacuum pump via a sealing structure. After the bottle is evacuated to a negative pressure state, the operator must manually tie a knot in the middle of the rubber tube and cut it to seal the tube and maintain the vacuum inside the bottle. However, this manual knotting method has the following shortcomings in actual operation: the sealing performance of the knot depends entirely on the tightness of the knot. If the knot is not tight or is pulled by external force, it is easy to leak air, disrupting the vacuum environment inside the bottle and causing blood collection failure. Moreover, the excess shortened rubber tube section after knotting easily leads to material waste. Therefore, we propose a bovine and ovine defibrinated blood collection device to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to solve the problem of inconvenience in using some current bovine and ovine defibrinated blood collection devices.

[0005] To achieve the above-mentioned objectives and improve the aforementioned problems, this utility model provides a bovine / ovine defibrinated blood collection device, comprising a bottle body, a base on the lower side of the bottle body, a connecting tube fixedly connected to the surface of the bottle body, the connecting tube communicating with the interior of the bottle body, a sealing plug at the end of the connecting tube, two first connecting blocks fixedly connected to the surface of the sealing plug, two second connecting blocks fixedly connected to the surface of the connecting tube, guide rods fixedly connected to the surfaces of the two second connecting blocks, the two first connecting blocks slidably sleeved on the outside of the two guide rods, a spring fixedly connected between the first and second connecting blocks, and the spring movably sleeved on the outside of the guide rods, a connecting pipe provided on the outside of the connecting tube, a sealing mechanism provided on the outside of the connecting tube, and a shaking mechanism provided on the surface of the base.

[0006] As a preferred technical solution of this application, the sealing mechanism includes a fixing ring, which is fixedly sleeved on the outside of the connecting pipe, and the outer surface of the fixing ring is provided with external threads.

[0007] As a preferred technical solution of this application, the inner ring surface of the connecting pipe is provided with an internal thread, the connecting pipe and the fixing ring are connected by the mating of the external thread and the internal thread, the connecting pipe is rotatably fitted with a connecting sleeve, and the connecting sleeve is fixedly fitted with a connecting tube.

[0008] As a preferred technical solution of this application, the base is provided with a fixing plate inside, the surface of the fixing plate is provided with a groove, the inner wall of the groove is provided with a rubber pad, and the groove is adapted to the bottle body.

[0009] As a preferred technical solution of this application, the shaking mechanism includes four rotating disks, which are rotatably connected to the adjacent surfaces of the two vertical plates on both sides of the base. Two fixed plates are fixedly connected to the lower surface of the fixed disk, and support rods are rotatably connected to both ends of the two fixed plates. The support rods are rotatably connected to the adjacent rotating disks, and the support rods are located at the eccentricity of the rotating disks.

[0010] As a preferred technical solution of this application, a cavity is provided inside the left vertical plate of the base, and two drive shafts are rotatably connected inside the cavity. Both drive shafts rotatably pass through the interior of the base, and the two drive shafts are respectively fixedly connected to two rotating disks on the left side.

[0011] As a preferred technical solution of this application, a synchronous pulley is fixedly sleeved at one end of each of the two drive shafts located inside the cavity, and a synchronous belt is sleeved on the outside of the two synchronous pulleys.

[0012] As a preferred technical solution of this application, a micro motor is fixedly connected to the surface of the base, and the output shaft of the micro motor rotates through the interior of the cavity and is fixedly connected to one of the transmission shafts.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In the scheme of this application:

[0015] 1. Through the cooperation of the sealing plug, first connecting block, second connecting block, guide rod, spring, fixing ring, and connecting pipe, after vacuuming is completed, the staff only needs to loosen the connecting pipe to separate it from the fixing ring. The spring can then automatically push the sealing plug into the end of the connecting pipe to achieve a seal by its own elasticity. There is no need to manually tie knots or cut the rubber tube, which simplifies the operation process, reduces the difficulty of operation, and avoids the risk of air leakage caused by loose knots or external pulling. This significantly improves the reliability of vacuum maintenance and the success rate of blood collection.

[0016] 2. Through the coordinated structure of the micro motor, drive shaft, synchronous pulley, synchronous belt, rotating disk, support rod, fixing plate, and fixing disc, the automatic reciprocating swing of the blood collection bottle is achieved, replacing the traditional manual shaking method. The micro motor drives the eccentrically arranged support rod to perform circular motion through the synchronous belt, causing the bottle to produce a compound swing motion. The glass beads roll evenly and slowly inside the bottle, resulting in good consistency of blood fiber entanglement and high defibrination efficiency. At the same time, it frees up the operator's hands, reduces labor intensity, and is suitable for batch defibrinated blood preparation scenarios. Attached Figure Description

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0026] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] Example 1

[0029] Please refer to Figures 1, 2, 3, 4, and 5. A bovine / sheep defibrinated blood collection device includes a bottle body 1, a base 2 on the lower side of the bottle body 1, a connecting pipe 3 fixedly connected to the surface of the bottle body 1, the connecting pipe 3 communicating with the interior of the bottle body 1, a sealing plug 4 at the end of the connecting pipe 3, two first connecting blocks 5 fixedly connected to the surface of the sealing plug 4, two second connecting blocks 6 fixedly connected to the surface of the connecting pipe 3, guide rods 7 fixedly connected to the surface of each of the two second connecting blocks 6, the two first connecting blocks 5 slidably sleeved on the outside of the two guide rods 7, a spring 8 fixedly connected between the first connecting blocks 5 and the second connecting blocks 6, and the spring 8 movably sleeved on the outside of the guide rods 7, a connecting pipe 9 on the outside of the connecting pipe 3, a sealing mechanism on the outside of the connecting pipe 3, and a shaking mechanism on the surface of the base 2.

[0030] In the above embodiment, under natural conditions, the spring 8 itself will pull the two first connecting blocks 5 and the sealing plug 4 toward one side of the connecting pipe 3, that is, the sealing plug 4 is firmly inserted into the interior of the connecting pipe 3.

[0031] Furthermore, when no operation is performed, the spring 8 is in a compressed state, causing the sealing plug 4 to be inserted into the end of the connecting tube 3. During the vacuuming operation, the external vacuuming equipment evacuates air from the inside of the connecting tube 3 through the connecting tube 9, reducing the air pressure inside the connecting tube 9, while the bottle body 1 maintains the initial atmospheric pressure, thereby creating a pressure difference on both sides of the sealing plug 4. This pressure difference is sufficient to overcome the elastic force of the spring 8, pushing the sealing plug 4 further out of the connecting tube 3, opening the air passage, and extracting the air from the bottle body 1.

[0032] When the vacuuming is completed, the air pressure inside the connecting pipe 9 rises back up. At this time, the inside of the bottle 1 is under negative pressure, and a pressure difference is formed on both sides of the sealing plug 4. This pressure difference is in the same direction as the return force of the spring 8, and together they push the sealing plug 4 to be quickly and tightly inserted into the end of the connecting pipe 3 to achieve a seal.

[0033] The bottle 1 contains 30 to 50 glass beads (not shown) with a diameter of 3 mm, which are used for fiber removal. Since this is a technical means known to those skilled in the art, it will not be described in detail here.

[0034] Furthermore, as shown in Figures 1, 2, 3, 4, and 5, the sealing mechanism includes a fixing ring 10, which is fixedly sleeved on the outside of the connecting pipe 3, and the outer surface of the fixing ring 10 is provided with an external thread 11.

[0035] Furthermore, as shown in Figures 1, 2, 3, 4, and 5, the inner ring surface of the connecting pipe 9 is provided with an internal thread 12. The connecting pipe 9 and the fixing ring 10 are connected by the mating of the external thread 11 and the internal thread 12. The connecting pipe 9 is rotatably fitted with a connecting sleeve 13, and the connecting sleeve 13 is fixedly fitted with a connecting pipe 14. In actual use, the operator connects the connecting pipe 14 to the external vacuum equipment, then fits the connecting pipe 9 on the outside of the fixing ring 10, and rotates it to make it threadedly connected, thereby realizing the connection between the connecting pipe 14 and the connecting pipe 3, which facilitates the vacuuming work.

[0036] Example 2

[0037] The bovine and ovine defibrinated blood collection device provided in Example 1 is further optimized. Specifically, as shown in Figures 1, 2, 3, 4, and 5, a fixing plate 15 is provided inside the base 2. A groove 16 is formed on the surface of the fixing plate 15. A rubber pad is provided on the inner wall of the groove 16. The groove 16 is adapted to the bottle body 1. By placing the bottle body 1 inside the groove 16, the rubber pad inside the groove 16 will be squeezed, thereby further improving the stability of the bottle body 1 inside the groove 16.

[0038] Furthermore, as shown in Figures 1, 2, 3, 4, and 5, the shaking mechanism includes four rotating disks 18. The four rotating disks 18 are rotatably connected to the adjacent surfaces of the two vertical plates on both sides of the base 2. Two fixed plates 17 are fixedly connected to the lower surface of the fixed disk 15. Support rods 19 are rotatably connected to both ends of the two fixed plates 17. The support rods 19 are rotatably connected to the adjacent rotating disks 18, and the support rods 19 are located at the eccentric position of the rotating disks 18. By rotating the rotating disks 18, the support rods 19 can be driven to perform circular motion, thereby driving the fixed plates 17 and the fixed disks 15 to perform a compound oscillating motion including up-down and left-right components. This allows the glass beads inside the bottle 1 to slowly roll, entangle the blood fibers in the blood, form a blood fiber core, and achieve the purpose of separating blood fibers. This can turn fresh blood into defibrinated blood, realizing the purpose of producing defibrinated blood on-site.

[0039] Furthermore, as shown in Figures 1, 2, 3, 4, and 5, a cavity 20 is provided inside the left vertical plate of the base 2. Two drive shafts 21 are rotatably connected inside the cavity 20. Both drive shafts 21 rotatably pass through the interior of the base 2, and the two drive shafts 21 are respectively fixedly connected to the two rotating disks 18 on the left side.

[0040] Furthermore, as shown in Figures 1, 2, 3, 4, and 5, a synchronous pulley 22 is fixedly sleeved at one end of each of the two drive shafts 21 inside the cavity 20, and a synchronous belt 23 is sleeved on the outside of the two synchronous pulleys 22.

[0041] Furthermore, as shown in Figures 1, 2, 3, 4, and 5, a micro motor 24 is fixedly connected to the surface of the base 2. The output shaft of the micro motor 24 rotates through the cavity 20 and is fixedly connected to one of the transmission shafts 21. The micro motor 24 is started by an external controller. The rotation of the output shaft of the micro motor 24 can drive the transmission shaft 21 connected to it to rotate. The rotation of the transmission shaft 21, along with the transmission of the synchronous pulley 22 and the synchronous belt 23, can drive the other transmission shaft 21 to rotate. The rotation of the two transmission shafts 21 can drive the rotation of the two rotating disks 18 on the left side.

[0042] The process of using the bovine and ovine defibrinated blood collection device provided by this utility model is as follows:

[0043] First, cover the bottle opening of bottle 1 with the sealing cap to seal the top opening. Before vacuuming, the sealing plug 4 is tightly pressed against the end of the connecting tube 3 by the elastic force of the spring 8, so that the connecting tube 3 is in a closed state and the inside of bottle 1 is isolated from the outside atmosphere.

[0044] Then, the staff connects the connecting pipe 14 to the external vacuum equipment, and puts the connecting pipe 9 on the outside of the fixing ring 10. The connecting pipe 9 and the fixing ring 10 are threaded together by the cooperation of the external thread 11 and the internal thread 12. Then the vacuum equipment is started. The vacuum equipment evacuates the air inside the connecting pipe 3 through the connecting pipe 14, the connecting pipe 9, and the fixing ring 10. As the vacuuming proceeds, the air pressure inside the connecting pipe 14 gradually decreases, while the bottle body 1 still maintains the initial atmospheric pressure, thus forming a pressure difference on both sides of the sealing plug 4. The high pressure side inside the bottle body 1 pushes the sealing plug 4 to overcome the elastic force of the spring 8, so that the sealing plug 4 moves along the guide rod 7 towards the outside of the connecting pipe 3 and automatically disengages from the end of the connecting pipe 3. The connecting pipe 3 then opens, and the air inside the bottle body 1 is extracted through the connecting pipe 3, the fixing ring 10, the connecting pipe 9, the connecting sleeve 13, and the connecting pipe 14. It opens automatically under the action of pressure difference without manual operation.

[0045] Once the required negative pressure is reached inside the bottle 1, the operator turns off the vacuum equipment and loosens the connecting pipe 9, separating it from the fixing ring 10. During this process, the air pressure inside the connecting pipe 9 rises, creating a negative pressure inside the bottle 1. A pressure difference is formed on both sides of the sealing plug 4. This pressure difference is aligned with the return force of the spring 8. Under the action of the spring 8 and the pressure difference, the first connecting block 5 is pulled to slide along the guide rod 7, jointly pushing the sealing plug 4 to quickly and tightly insert into the end of the connecting pipe 3, achieving a tight seal on the connecting pipe 3 and maintaining the vacuum state inside the bottle 1. The entire process does not require manual knotting or cutting of the rubber tube; the automatic opening and closing of the air passage can be completed solely by the pressure difference change and the elastic return of the spring 8.

[0046] Finally, blood is collected after sterilization. After blood collection, the bottle 1 is placed in the groove 16 on the surface of the fixed plate 15. The micro motor 24 is started. The micro motor 24 drives the rotating plate 18 to rotate through the transmission shaft 21, the synchronous pulley 22, and the synchronous belt 23. The rotating plate 18 drives the fixed plate 17 and the fixed plate 15 to perform compound reciprocating motion through the eccentrically set support rod 19. The glass beads inside the bottle 1 slowly roll during the motion, wrapping the blood fibers in the blood to form a blood fiber core, realizing the separation of blood fibers, and converting fresh blood into defibrinated blood.
