Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of umbilical cord blood separation devices, in particular to a blood plasma separation clamp for umbilical cord blood separation. Background Technique
[0002] Umbilical cord blood is the blood remaining in the placenta and umbilical cord after the fetus is delivered, the umbilical cord is ligated and severed. Umbilical cord blood is rich in stem cells and can be used for stem cell transplantation instead of bone marrow. In order to facilitate the preparation of umbilical cord blood, umbilical cord blood will be separated. The common separation method is to use a blood plasma separation clamp to separate the blood, which is widely used in hospitals, blood stations, etc. After the plasma in the blood bag is stratified, the pressure of the plasma separation clamp can be used to squeeze out different components of the blood from top to bottom.
[0003] During the use of the blood plasma separation clamp, usually, since one corner of the clamping plate is installed on one side of the side plate, and a handle is installed outside the clamping plate, by pushing the handle upward, that is, the handle drives the clamping plate to squeeze the blood bag, the umbilical cord blood stored inside the blood bag can be driven to be separated. However, there are differences in the size of the blood bag and the content of the filled plasma inside. During the extrusion of the blood bag by the conventional plasma separation clamp, the blood bag can move to the lower end of the connection between the clamping plate and the side plate. When controlling the extrusion of the clamping plate, since there is an included angle between the clamping plate and the side plate, and the lower end of the blood bag moves between the included angles, the blood bag affects the continuous extrusion of the clamping plate, thereby affecting the separation effect of the blood bag. Moreover, after applying too much force to the clamping plate, the moving space of the blood bag between the side plate and the clamping plate is too low, resulting in the clamping plate squeezing and damaging the blood bag. Therefore, we propose a blood plasma separation clamp for umbilical cord blood separation. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0022] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , a blood plasma separation clamp for umbilical cord blood separation, including a base 1, a side plate 2 is fixedly connected to the side of the base 1, a push rod 7 is movably sleeved on the side of the base 1, the push rod 7 limits the position of the pressing plate 15, and at the same time, the control handle 8 is rotated. When the control handle 8 drives the push rod 7 to turn upward, the push rod 7 can push the pressing plate 15 to move inward, that is, the pressing plate 15 can perform separation processing on the blood bag. A vertical plate 9 is movably sleeved on the upper part of the base 1, the position of the vertical plate 9 can be adjusted, and the vertical plate 9 drives the distance between the pressing plate 15 and the side plate 2 to be adjusted. A connecting sleeve 12 is movably sleeved inside the front end of the vertical plate 9, and the connecting sleeve 12 can drive the angle of the pressing plate 15 to be adjusted. A first clamping plate 13 is fixedly connected to the front end of the side of the connecting sleeve 12, the first clamping plate 13 drives the position of the pressing plate 15 to be clamped and limited, the pressing plate 15 is clamped inside the first clamping plate 13, and a slide rail 16 is opened inside the side of the pressing plate 15, and the slide rail 16 provides a moving space for the first clamping plate 13 and the second clamping plate 17.
[0023] Refer to Figure 1 and Figure 5, a chute is provided inside the side plate 2. At the same time, a screw rod 3 is movably sleeved inside the chute. The end of the screw rod 3 is conical. A threaded sleeve 4 with a conical inner side at the end is threadedly sleeved outside the screw rod 3. A connecting rope 5 is movably sleeved on the screw rod 3. One side of the connecting rope 5 is fixedly connected to an elastic pull rope 6. The elastic pull rope 6 is sleeved outside the blood bag. By providing a chute inside the side plate 2, the position of the screw rod 3 inside the chute can be adjusted. According to the different sizes of the blood bags, the elastic pull rope 6 is controlled to be arranged outside the blood bag, and the position of the connecting rope 5 inside the screw rod 3 is adjusted. That is, the elastic pull rope 6 can tighten and fix the position of the blood bag on the side of the side plate 2. At the same time, the threaded sleeve 4 is rotated. Threaded movement occurs between the threaded sleeve 4 and the screw rod 3. At the same time, the threaded sleeve 4 drives the end of the screw rod 3 to be squeezed. After the end of the screw rod 3 is tightened, the screw rod 3 squeezes and limits the position of the connecting rope 5, improving the stability of the connecting rope 5 when its position is limited inside the screw rod 3.
[0024] Reference Figure 1 , the push rod 7 is L-shaped. A control handle 8 is fixedly connected to the middle of the push rod 7. At the same time, a second clamping plate 17 is installed at the other end of the push rod 7. One end of the push rod 7 is installed outside the base 1. By rotating the control handle 8, the angle of the push rod 7 is adjusted. At the same time, a second clamping plate 17 is installed on the other side of the push rod 7. That is, the second clamping plate 17 is driven to rotate with one end of the push rod 7 as the center of the circle. Thus, the second clamping plate 17 can push the pressing plate 15 to move inward. That is, after the pressing plate 15 squeezes the blood bag, the cord blood placed in the blood bag can be separated and processed.
[0025] Reference Figure 2 , the second clamping plate 17 is movably sleeved inside the slide rail 16. The pressing plate 15 is located at the front end of the side plate 2. Due to the end of the push rod 7 moving in a circular motion, the angle of the pressing plate 15 can be pushed to be adjusted. At the same time, the second clamping plate 17 is sleeved inside the slide rail 16. That is, the second clamping plate 17 slides inside the slide rail 16, and when the pressing plate 15 is ensured to move inward, the stability of the device is improved.
[0026] Reference Figure 3 , a slide rod 10 is fixedly connected to the lower end of the vertical plate 9. And the slide rod 10 is installed inside the chute opened at the lower end of the base 1. A threaded rod 11 is threadedly installed inside the slide rod 10. The threaded rod 11 is arranged on both sides inside the base 1. By driving the slide rod 10 by the vertical plate 9 to be installed at the lower end of the base 1 and rotating the threaded rod 11, threaded movement occurs between the threaded rod 11 and the slide rod 10, and the vertical plate 9 can be pushed to move on the upper part of the base 1. By moving the vertical plate 9 inward, the distance between the lower end of the pressing plate 15 and the side plate 2 can be adjusted. That is, during the process of squeezing the blood bag, when the blood content and thickness inside the blood bag are different, the squeezing depth can be adjusted to avoid the distance between the side plate 2 and the pressing plate 15 being too small, resulting in too large a squeezing force and thus damaging the squeezed blood bag.
[0027] Reference Figure 4 , the connecting sleeve 12 is sleeved inside the front end of the vertical plate 9. The vertical plate 9 is vertically installed on the upper part of the base 1. By being arranged at the front end of the vertical plate 9 through the connecting sleeve 12, that is, the connecting sleeve 12 can rotate around the vertical plate 9. When rotating the control handle 8, the connecting sleeve 12 can be synchronously carried to rotate around the front end of the vertical plate 9 for processing.
[0028] Reference Figure 2 , a fastening bolt 14 is installed inside the side surface of the first clamping plate 13. The fastening bolt 14 passes through the first clamping plate 13 and is simultaneously fitted and installed inside the side surface of the slide rail 16. By sleeving the first clamping plate 13 on the side surface of the pressing plate 15, the position of the pressing plate 15 inside the first clamping plate 13 is controlled, that is, the height of the pressing plate 15 at the upper end of the base 1 is adjusted or the pressing plate 15 is disassembled and replaced. And by rotating the fastening bolt 14, the position between the first clamping plate 13 and the pressing plate 15 is spliced and limited.
[0029] Working principle: When in use, according to the different sizes of blood bags, rotate the threaded rod 11. The threaded rod 11 drives the vertical plate 9 to adjust its position on the upper part of the base 1. At the same time, control the position of the pressing plate 15 inside the first clamping plate 13, rotate the fastening bolt 14, and the fastening bolt 14 splices and limits the position between the first clamping plate 13 and the pressing plate 15. At the same time, control the blood bag to be placed on the side surface of the side plate 2, adjust the position of the screw rod 3, and tighten the installation connecting rope 5. Control the elastic pull rope 6 to be sleeved outside the blood bag to improve the stability of the blood bag when its position is limited on the side surface of the side plate 2. And rotate the control handle 8, the control handle 8 drives the push rod 7 to move to the other side. At the same time, the push rod 7 pushes the top end of the pressing plate 15 to rotate, and the pressing plate 15 can squeeze the blood bag clamped on the side plate 2. Thus, the blood bag can be driven to be separated.
