Description

Technical Field

[0001] This application relates to the field of blood separator technology, and in particular to a splash-proof blood component separator. Background Technology

[0002] After centrifugation, the blood in a whole blood bag will be divided into three layers: a plasma layer on top, a white membrane layer (platelets, very few in number and very thin), and a red blood cell layer at the bottom. A blood component separator is used to divide a bag of blood into several smaller bags or to separate the various components after centrifugation. Chinese utility model patent CN201132383Y discloses a plasma bag bubble squeezer, which separates the various components in the blood bag by squeezing with a squeeze plate.

[0003] During the process of squeezing the blood bag, excessive pressure can easily cause the blood bag to rupture. When the blood bag ruptures, it can cause blood to splatter, resulting in blood all around and on the outer surface of the blood component separator, which is inconvenient to clean. Utility Model Content

[0004] The purpose of this application is to provide a splash-proof blood component separator that can reduce the occurrence of blood splashing due to blood bag rupture.

[0005] The anti-splash blood component separator provided in this application adopts the following technical solution:

[0006] A splash-proof blood component separator, comprising:

[0007] Separator body;

[0008] A pressure plate is disposed on one side of the separator body and can move toward or away from the separator body, and there is a squeezing space between the pressure plate and the separator body;

[0009] A baffle is disposed above the pressure plate and is used to block the compression space.

[0010] Optionally, it also includes a support frame, which is fixed to the separator body, one end of the baffle is connected to the support frame, the other end of the baffle overlaps the separator body, and the baffle is inclined.

[0011] Optionally, the baffle is hinged to the support frame.

[0012] Optionally, a shield is also included, which is disposed on the side of the pressure plate away from the separator body and the bottom surface of the shield is lower than the top surface of the pressure plate, and the shield is fixed on the support frame.

[0013] Optionally, the shield can be detachably attached to the support frame.

[0014] Optionally, the shield includes a connecting part and a blocking part, wherein the connecting part is fixed to the blocking part and detachably connected to the top surface of the support frame.

[0015] Optionally, a plurality of the shields are provided, and the plurality of the shields are arranged horizontally on the support frame.

[0016] This application incorporates baffles and shields that can block splashed blood when a blood bag ruptures, thus reducing the amount of blood splattering and minimizing blood splashing on the operating parts of the separator. This facilitates cleaning of the blood on the separator body after the blood bag ruptures. Furthermore, the baffles and shields significantly reduce the area of ​​blood splashing, requiring only the removal of the baffles, shields, and a small amount of blood splashed on the ground, making cleaning quick and easy.

[0017] In this application, the mask is detachably connected to the support frame. When the mask is contaminated with blood, it can be removed and cleaned easily. Attached Figure Description

[0020] Figure 3 This is a schematic diagram of the structure of the baffle and shield in the embodiments of this application.

[0021] In the figure, 1 is the separator body; 11 is the extrusion surface; 12 is the hanging part; 2 is the pressure plate; 3 is the baffle; 4 is the support frame; 5 is the cover; 51 is the connecting part; and 52 is the shielding part. Detailed Implementation

[0022] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail below.

[0023] A splash-proof blood component separator, as described above Figure 1 and Figure 2The separator includes a separator body 1 and a pressure plate 2. The separator body 1 has a compression surface 11 on its side wall, and a hanging part 12 for hanging blood bags is fixed on the compression surface 11. In other embodiments, clamps or other structures can also be used to fix the blood bags to the compression surface 11. The pressure plate 2 can move towards or away from the separator, that is, move away from or towards the direction away from the compression surface 11. During the use of the separator, the blood bags are first fixed to the compression surface 11, and then the pressure plate 2 is controlled to move towards the compression surface 11, thereby squeezing the blood bags and separating the blood components within them.

[0024] Specifically, there is a compression space (not shown in the figure) between the pressure plate 2 and the compression surface 11. The blood bag is fixed on the compression surface 11, that is, it is located in the compression space. As the pressure plate 2 moves closer to or away from the compression surface 11, the compression space continuously increases or decreases, compressing the space where the blood bag is located, thereby squeezing the blood bag, that is, separating the blood inside the blood bag.

[0025] Specifically, the separator body 1 is equipped with a drive mechanism (not shown in the figure), which is connected to the pressure plate 2. Driven by the drive mechanism, the pressure plate 2 is moved. In this embodiment, the drive mechanism can be an electric telescopic rod. In other embodiments, it can also be a telescopic cylinder or other mechanism that can move the pressure plate 2 toward or away from the extrusion surface 11.

[0026] Furthermore, the hanging part 12 on the extrusion surface 11 is located above the pressure plate 2. The drive mechanism is set inside the separator body 1 and the output end extends out of the separator body 1 and is fixed on the pressure plate 2. During daily storage, the drive mechanism can drive the pressure plate 2 to move closer to the extrusion surface 11, and finally make the pressure plate 2 fit against the extrusion surface 11, thereby reducing the space occupied by the separator and facilitating storage.

[0027] Reference Figure 2 and Figure 3 Furthermore, the separator also includes a baffle 3, which is positioned above the pressure plate 2 and serves to shield the compression space. Generally, blood bags have upper and lower seals, and the transmission pipes are inserted into the blood bag from these seals. Therefore, during compression, the upper and lower parts of the blood bag are prone to bursting open, causing blood to splash. The upper part of the separator body 1 is usually the operating area, and blood splashing onto this area is difficult to clean. By placing the baffle 3 above the compression space, when the upper part of the blood bag bursts open, the baffle 3 blocks the splashing blood, reducing blood splashing onto the operating area. When cleaning, only the baffle 3 and the compression surface 11 need to be cleaned, making cleaning more convenient. When the lower part of the blood bag bursts open, the blood splashes directly onto the ground, which is also relatively easy to clean, thus eliminating the need for the baffle 3.

[0028] In other embodiments, baffles 3 can also be provided on both sides of the pressure plate 2. When the blood bag bursts open on both sides, the baffles 3 on both sides can shield the blood and reduce the splashing of blood. Whether or not to provide baffles 3 can be adjusted according to the structure of the blood bag. When the blood bag is easy to burst open on both sides, the baffles 3 are provided on both sides of the pressure plate 2. Otherwise, they are not necessary.

[0029] Furthermore, the baffle 3 is inclined from top to bottom and away from the separator body 1. When blood splashes onto the baffle 3, the blood can flow along the baffle 3 away from the separator body 1, finally gathering at the lower edge of the baffle 3 and dripping onto the ground, further reducing the possibility of blood dripping onto the separator body 1. In other embodiments, the baffle 3 can also be horizontally arranged above the pressure plate 2, as long as it can block the compression space.

[0030] Specifically, a support frame 4 is fixedly connected to the separator body 1. One end of the baffle 3 is connected to the support frame 4, and the other end is attached to the separator body 1, thereby achieving the inclined setting of the baffle 3. In other embodiments, the baffle 3 can also be inclined by connecting it to the separator body 1 and attaching it to the support frame 4.

[0031] Furthermore, the baffle 3 is hinged to the support frame 4. Before placing the blood bag, the baffle 3 can be rotated to remove the obstruction of the compression space, making it easier to place the blood bag into the compression space. After the blood bag is fixed, the baffle 3 can be rotated again to overlap the separator body 1, and then the blood bag can be compressed. In other embodiments, the baffle 3 can be directly fixed to the support frame 4.

[0032] Furthermore, it also includes a shield 5, which is fixed on the support frame 4 and set on the side of the pressure plate 2 away from the separator body 1. The bottom surface of the shield 5 is lower than the top surface of the baffle 3. The baffle 3 blocks the blood splashing upwards, and the shield 5 blocks the blood splashing horizontally, further reducing the occurrence of blood splashing and facilitating cleaning.

[0033] Furthermore, the mask 5 is detachably connected to the support frame 4, which facilitates the removal and cleaning of the mask 5. In this embodiment, the mask 5 is detachably connected to the support frame 4 by bolts. In other embodiments, the mask 5 can be fixed to the support frame 4 by clips or other components, as long as the detachable connection between the mask 5 and the support frame 4 is achieved.

[0034] Furthermore, the shield 5 includes a connecting part 51 and a blocking part 52. The connecting part 51 and the blocking part 52 are fixedly connected to each other and are L-shaped. The connecting part 51 is horizontally laid on the top surface of the support frame 4 and is detachably connected to the support frame 4 by bolts. The blocking part 52 extends downward below the top surface of the pressure plate 2. By having the connecting part 51 laid flat on the top surface of the support frame 4, it is convenient to connect the connecting part 51 to the support frame 4, that is, it is convenient to fix the shield 5 to the support frame 4. In this embodiment, the shield 5 is first fixed to the support frame 4, and then the baffle 3 is hinged to the connecting part 51, thereby realizing the hinge between the baffle 3 and the support frame 4.

[0035] Furthermore, the number of covers 5 is set to several, and several covers 5 are horizontally arranged on the support frame 4. The separator can be equipped with multiple pressure plates 2 to squeeze and separate multiple blood bags at the same time. Each cover 5 corresponds to a pressure plate 2, so that when one blood bag ruptures, the blood-contaminated cover 5 can be removed and cleaned separately, while the other covers 5 can continue to work. In addition, the number of covers 5 is set to several, and the length of each cover 5 is small, which facilitates manufacturing, transportation and installation.

[0036] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
