[0002] A blood separator is a device used to separate blood components. The specific separation process involves first centrifuging the blood at high speed to create layers, then using the blood separator to squeeze each layer of blood into a whole blood bag and input it into a corresponding collection bag, thus achieving the purpose of blood component separation. Blood separators are mainly of two types: automatic and manual. Automatic separators require electricity, while manual separators do not and can operate normally even during power outages.

[0003] However, existing blood separation devices still have shortcomings. For example, manual and electric blood separation devices are separate devices that are not integrated together, making them inconvenient to use and taking up a lot of space. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a blood separation device that can be used both automatically and manually, thus solving the technical problem that existing manual and electric blood separation devices are separate devices that are not integrated together, making them inconvenient to use and taking up a lot of space.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: This utility model provides a blood separation device that can be used both automatically and manually, comprising: Organism; A manual separation assembly includes a fixed plate and a movable plate. The fixed plate is disposed on the machine body, and the movable plate is rotatably connected to the machine body, forming a first clamping space between the movable plate and the fixed plate for clamping the blood mother bag. An automatic separation assembly is provided on the machine body. The automatic separation assembly includes a pressure plate and an electric drive unit. The pressure plate is slidably connected to the machine body and forms a second clamping space between it and the fixed plate. The electric drive unit is connected to the pressure plate and is used to drive the pressure plate to move closer to or away from the fixed plate.

[0006] In some embodiments, the pressure plate is located on the side of the fixed plate opposite to the movable plate.

[0007] In some embodiments, the manual separation assembly further includes a rotating shaft and a handle, the movable plate being connected to the rotating shaft, the rotating shaft being rotatably connected to the body, and the handle being connected to the rotating shaft.

[0008] In some embodiments, the manual separation assembly further includes a torsion spring disposed on the pivot and capable of accumulating elastic force when the movable plate rotates to expand the first clamping space. The torsion spring is also capable of releasing elastic force to drive the movable plate to rotate toward the fixed plate to compress the first clamping space.

[0009] In some embodiments, a third clamping space is formed between the side of the pressure plate facing away from the fixing plate and the machine body.

[0010] In some embodiments, the automatic separation assembly further includes a first blood bag fixing mechanism and a second blood bag fixing mechanism, wherein the first blood bag fixing mechanism is disposed on the side of the body facing the pressure plate, and the second blood bag fixing mechanism is disposed on the side of the fixing plate facing the pressure plate.

[0011] In some embodiments, the first blood bag fixing mechanism and the second blood bag fixing mechanism have the same structure. The first blood bag fixing mechanism includes a first hanging needle, a second hanging needle, a first movable pin, and a second movable pin. The first movable pin and the second movable pin are vertically arranged and are both located between the first hanging needle and the second hanging needle.

[0012] In some embodiments, both the first movable pin and the second movable pin are rotatably connected to the body and both have notches for the mouth of the blood mother bag to pass through. When the first movable pin and the second movable pin rotate in opposite directions, they can break the mouth of the blood mother bag.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] To address the technical problem that existing manual and electric blood separation devices are separate devices that are not integrated, making them inconvenient to use and space-consuming, this utility model provides a blood separation device that can be used both automatically and manually, integrating the manual and automatic blood separation devices together, making it convenient to use and occupying little space.

[0019] It should be noted that the automatic and manual blood separation device described in this utility model is used in, but not limited to, blood bags. For ease of explanation, this utility model only uses the application of the automatic and manual blood separation device in blood bags as an example. The principle of the automatic and manual blood separation device in other types of equipment is essentially the same as that in blood bags, and will not be described in detail here.

[0020] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a blood separation device that can be used both automatically and manually according to an embodiment of the present invention. The blood separation device includes a body 1, a manual separation component 2, and an automatic separation component 3. The manual separation component 2 includes a fixed plate 21 and a movable plate 22. The fixed plate 21 is disposed on the body 1, and the movable plate 22 is rotatably connected to the body 1, forming a first clamping space 23 between the movable plate 22 and the fixed plate 21 for clamping the blood mother bag 4. The automatic separation component 3 is disposed on the body 1 and includes a pressure plate 31 and an electric drive component 32. The pressure plate 31 is slidably connected to the body 1 and forms a second clamping space 33 between the pressure plate 31 and the fixed plate 21. The electric drive component 32 is connected to the pressure plate 31 and is used to drive the pressure plate 31 closer to or away from the fixed plate 21.

[0021] In this embodiment, the main body 1 serves as the supporting frame for the entire device, used to fix and install other components. The main body 1 mainly includes a base 11 and a base 12. The base 12 is mounted on the base 11 and is used to store circuit boards, drive components, and other parts. The manual separation component 2 is located on the base 11, and the automatic separation component 3 is located on the base 12. They are integrated together in this way and can be used simultaneously or separately, making them convenient to use and occupying little space.

[0022] The manual separation component 2 uses a purely mechanical structure to squeeze the blood mother bag 4 during use. It does not require electricity and can be used anytime and anywhere, making it particularly suitable for use during power outages, thus demonstrating its practicality. Specifically, first, rotate the movable plate 22 to open the first clamping space 23, place the blood mother bag 4 into the first clamping space 23, and then manually drive the movable plate 22 to rotate, which, in conjunction with the fixed plate 21, squeezes the blood mother bag 4, causing the stratified liquid in the blood mother bag 4 to flow sequentially into each of the daughter bags.

[0023] The automatic separation component 3 uses an electric motor to squeeze the blood mother bag 4 during use. Only manual intervention is required to place the blood mother bag 4 into the second clamping space 33 for fixation. The entire process is automated, eliminating the need for manual operation. It is convenient to use, highly efficient, and accurate. Specifically, after placing the blood mother bag 4 into the second clamping space 33, the control program is activated, controlling the electric drive component 32 to move the pressure plate 31 towards the fixing plate 21. The pressure plate 31 first contacts the blood mother bag 4, and as it continues to move, it squeezes the blood mother bag 4, sequentially squeezing the stratified liquid into each of the daughter bags.

[0024] In one embodiment, such as Figure 1 As shown, the pressure plate 31 is located on the side of the fixed plate 21 facing away from the movable plate 22. In this embodiment, the pressure plate 31 and the movable plate 22 are located on different sides of the fixed plate 21, so that the pressure plate 31 and the movable plate 22 do not interfere with each other during operation. They can independently complete the blood separation work of the blood mother bags 4 on each side, and can squeeze two blood mother bags 4 at the same time, which is beneficial to improving work efficiency. In other embodiments, the pressure plate 31 and the movable plate 22 can also be located on the same side of the fixed plate 21. However, in this embodiment, only one of the movable plate 22 and the pressure plate 31 can be used to squeeze the blood mother bag 4 at a time. This embodiment has a more compact structure and occupies less space.

[0025] In one embodiment, such as Figure 1As shown, the manual separation component 2 also includes a rotating shaft 24 and a handle 25. The movable plate 22 is connected to the rotating shaft 24, and the rotating shaft 24 is rotatably connected to the machine body 1. The handle 25 is connected to the rotating shaft 24. In this embodiment, a force is applied manually to the handle 25, causing the handle 25 to drive the rotating shaft 24 to rotate. In turn, the rotating shaft 24 drives the movable plate 22 to rotate, thereby adjusting the size of the first clamping space 23. This allows for convenient placement or removal of the blood mother bag 4 into or from the first clamping space 23. Furthermore, the blood mother bag 4 can be manually squeezed and separated by operating the handle 25.

[0026] In one embodiment, the manual separation component 2 further includes a torsion spring (not shown in the figure). The torsion spring is located on the rotating shaft 24 and can accumulate elastic force when the movable plate 22 rotates to expand the first clamping space 23. The torsion spring can also release the elastic force to drive the movable plate 22 to rotate toward the fixed plate 21 to compress the first clamping space 23. In this embodiment, by setting the torsion spring, the movable plate 22 can be operated more effortlessly. When the operator releases the handle 25, the torsion spring can automatically drive the movable plate 22 to rotate toward the fixed plate 21 to squeeze the blood mother bag 4, thereby improving the efficiency and convenience of manual separation.

[0027] In one embodiment, such as Figure 3 As shown, a third clamping space 34 is formed between the side of the pressure plate 31 facing away from the fixed plate 21 and the machine body 1. The third clamping space 34 in this embodiment can also be used to clamp the blood mother bag 4. Since the pressure plate 31 is located between the fixed plate 21 and the machine base 12, when the pressure plate 31 moves closer to the fixed plate 21, it also gradually moves away from the machine base 12; conversely, when the pressure plate 31 moves away from the fixed plate 21, it also gradually moves closer to the machine base 12. In this embodiment, both the fixed plate 21 and the machine base 12 can accommodate the blood mother bag 4. When the pressure plate 31 moves closer to or further away from the fixed plate 21, it can compress two blood mother bags 4, further improving work efficiency.

[0028] Further, please refer to Figure 1 and Figure 2As shown, the automatic separation assembly 3 also includes a first blood bag fixing mechanism 35 and a second blood bag fixing mechanism 36. The first blood bag fixing mechanism 35 is located on the side of the base 12 facing the pressure plate 31, and the second blood bag fixing mechanism 36 is located on the side of the fixing plate 21 facing the pressure plate 31. In this embodiment, both the first blood bag fixing mechanism 35 and the second blood bag fixing mechanism 36 can be used to stably fix the blood mother bag 4, ensuring the stability and reliability of the blood mother bag 4 during the automatic separation process, preventing the blood mother bag 4 from shifting or falling off during separation, thereby ensuring the separation effect and quality. The blood mother bag 4 fixed by the first blood bag fixing mechanism 35 is located in the third clamping space 34, and the blood mother bag 4 fixed by the second blood bag fixing mechanism 36 is located in the second clamping space 33. When the pressure plate 31 moves in one direction, it can only squeeze one blood mother bag 4 at a time. When the pressure plate 31 moves toward the first blood bag fixing mechanism 35, it can squeeze the blood mother bag 4 fixed by the fixing mechanism. After squeezing the blood mother bag 4, the electric drive unit 32 can drive the pressure plate 31 to move toward the second blood bag fixing mechanism 36 to squeeze the blood mother bag 4 fixed by the second blood bag fixing mechanism 36.

[0029] Furthermore, such as Figure 2 As shown, the first blood bag fixing mechanism 35 and the second blood bag fixing mechanism 36 have the same structure. The first blood bag fixing mechanism 35 includes a first hanging pin 351, a second hanging pin 352, a first movable pin 353, and a second movable pin 354. The first movable pin 353 and the second movable pin 354 are vertically arranged and both are located between the first hanging pin 351 and the second hanging pin 352. In this embodiment, by setting the first hanging pin 351 and the second hanging pin 352, the hanging holes of the blood mother bag 4 can be hung to suspend and fix the blood mother bag 4. The first movable pin 353 and the second movable pin 354 can further fix the bag mouth of the blood mother bag 4, improving the stability of the fixation.

[0030] Furthermore, such as Figure 2As shown, both the first movable pin 353 and the second movable pin 354 are rotatably connected to the machine body 1, specifically to the machine base 12. Both the first movable pin 353 and the second movable pin 354 have notches for the mouth of the blood mother bag 4 to pass through. When the first movable pin 353 and the second movable pin 354 rotate in opposite directions, they can break the mouth 41 of the blood mother bag 4. This design not only secures the blood mother bag 4 but also allows for the breaking of the mouth 41, enabling the blood mother bag 4 to be sealed through the mouth 41 when not in use, preventing the blood stored in the blood mother bag from being contaminated by air. When blood separation from the blood mother bag 4 is required, the blood mother bag 4 can be connected to each of the daughter bags first, and then the mouth 41 can be broken to connect the blood mother bag 4 to each of the daughter bags. When the blood mother bag 4 is squeezed, the blood inside can be separated into the respective daughter bags for storage. The entire device has more diverse functions, reduces the inconvenience of needing additional tools to cut the mouth during blood separation, and improves work efficiency.

[0031] In one embodiment, such as Figure 4 As shown, the electric drive unit 32 includes a motor 321, a lead screw 322, a slider 323, and a slide bar 324. The slider 323 is slidably mounted on the machine body 1. The slide bar 324 connects the slider 323 and the pressure plate 31. The motor 321 is connected to the lead screw 322, and the lead screw 322 is threadedly connected to the slider 323. In this embodiment, the motor 321 drives the lead screw 322 to rotate, and the lead screw 322 then drives the slider 323 to slide along the machine body 1 via the thread. The slider 323 pushes the pressure plate 31 closer to or further away from the fixed plate 21 via the slide bar 324, thereby achieving automatic compression and separation of the blood mother bag 4. This electric drive method makes the automatic blood separation process more stable, precise, and controllable, and can be adjusted and controlled according to different blood separation requirements.

[0032] In one embodiment, such as Figure 1 As shown, there are multiple and identical manual separation components 2 and automatic separation components 3, all arranged along the length of the body 1. This embodiment, by arranging multiple manual separation components 2 and automatic separation components 3, enables the blood separation device to process multiple blood mother bags 4 simultaneously, greatly improving the efficiency of blood separation and meeting the needs of large-scale blood separation. It is particularly suitable for situations requiring rapid processing of large numbers of blood samples, such as hospitals and blood banks.

[0033] To better understand this utility model, the following is combined with... Figures 1 to 4 The technical solution of this utility model is described in detail below: The blood separation device provided by this utility model, which can be used both automatically and manually, has a manual separation component that allows for manual compression of the blood mother bag 4. Specifically, the blood mother bag 4 is first placed in the first clamping space 23, and then the movable plate 22 is manually driven to rotate and compress the blood mother bag 4. The automatic separation component 3 involves first placing the blood mother bag 4 in the second clamping space 33, and then using an electric drive component 32 to move the pressure plate 31 closer to the fixed plate 21 to compress the blood mother bag 4. Therefore, this application integrates the manual separation component 2 and the automatic separation component 3 together, allowing for simultaneous use to improve work efficiency. It is convenient to use and occupies little space.
