Description

Technical Field

[0001] The present invention relates to the technical field of blood filtration, and in particular to a blood filtration system and a blood filtration method. Background Art

[0002] Blood transfusion is an important rescue and treatment measure in clinical practice. It can save the patient's life, but it may also cause harm to the patient. Modern blood transfusion requires the removal of white blood cells to ensure the safety of blood transfusion. The leukocyte filtration of blood bags needs to be performed through a blood bag system that sets up blood bags and collection bags.

[0003] For example, the blood bag system disclosed in the patent document with announcement number CN202554575U includes a catheter, a blood introduction part, a filter, a clamping piece, a blood recovery bag, and a bypass flow path. The catheter is used for blood to pass through. The blood introduction part is arranged at the upper end of the catheter, and the blood recovery bag is arranged at the lower end of the above-mentioned catheter. The filter is installed on the catheter, which can remove white blood cells from the blood and filter the blood flowing from the blood introduction part to the blood recovery bag. The bypass flow path bypasses the filter and is connected to the catheter. The clamping piece is arranged on the catheter and the bypass flow path, and can block the catheter and the bypass flow path by clamping the catheter and the bypass flow path. Through the above settings of the blood bag system, before performing blood leukofiltration, the blood bag system is first suspended by the blood introduction part, and then the clamping piece clamps the bypass flow path. During leukofiltration, the blood in the blood introduction part flows into the catheter by gravity, and is leukofiltered by the filter when passing through the filter. After leukofiltration, the blood enters the blood recovery bag, and finally the leukofiltered blood is collected.

[0004] Although the blood bag system can be used to filter blood and collect filtered blood, when entering the white filtering process, the suspended blood inlet part, i.e., the air inlet valve of the blood bag, needs to be manually broken off to allow the blood to flow out of the blood bag. This requires a lot of manpower in the early stage of blood filtering, and the efficiency is reduced by manual breaking, resulting in low white filtering efficiency, which makes it difficult to meet the white filtering needs of large quantities of blood in the blood station. Summary of the invention

[0009] In some embodiments, the limiting member and the hanging member are arranged at an angle with the width direction of the frame, so that the blood bag can be hung obliquely relative to the frame.

[0010] In some embodiments, the hanging unit also includes a first gravity sensing module, which is connected to the frame and the hanger and electrically connected to the adjustment drive component for sensing the gravity of the hanger so that the adjustment drive component drives the hanger to rise after hanging the blood bag.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] Modern blood transfusion requires the removal of white blood cells to ensure transfusion safety. White blood cells in the blood are generally removed by filtration, referred to as leukocyte filtration. Since the existing leukocyte filtration work is mainly performed by manual operation and the amount of blood in the blood station is large, the leukocyte filtration work of blood in the existing technology requires a large amount of manpower and has low leukocyte filtration efficiency, which is difficult to meet the leukocyte filtration needs of the blood station.

[0021] In order to solve the technical problems that the blood leukofiltration process in the prior art consumes a lot of manpower and has a low leukofiltration efficiency, such as Figure 1 As shown, the present invention provides a leukofiltration system, which is used to suspend a blood bag device 10a to leukofiltration blood. The blood bag device 10a includes a blood bag 11a, a catheter 12a, a leukofiltration module 13a and a collecting bag 14a. The catheter 12a connects the blood bag 11a and the collecting bag 14a. The leukofiltration module 13a is connected to the catheter 12a to leukofiltration the blood flowing therethrough. The leukofiltration system can realize automatic leukofiltration of blood, reduce the manpower consumed in blood leukofiltration, and improve the leukofiltration efficiency of blood.

[0022] The bleaching system provided by the embodiment of the present invention is as follows: Figure 1 As shown, it includes a frame 10, a hanging unit 20, a supporting unit 30 and a breaking unit 40. The hanging unit 20 is installed on the top of the frame 10 and is used to hang the blood supply bag 11a; the supporting unit 30 is installed on the top of the frame 10 and is used to support the collecting bag 14a; the breaking unit 40 is installed on the hanging unit 20 and is used to break the air inlet valve 111a of the blood bag 11a.

[0023] Specifically, the white filter system is provided with a frame 10, a hanging unit 20, a supporting unit 30 and a breaking unit 40. The hanging unit 20 and the supporting unit 30 are respectively installed at the top and the bottom of the frame 10. The hanging unit 20 can hang the blood bag 11a of the blood bag device 10a, and the supporting unit 30 can support the collecting bag 14a of the blood bag device 10a. When performing white filter work, the blood bag 11a filled with blood is hung on the hanging unit 20, and the air inlet valve 111a of the blood bag 11a is connected to the breaking unit 40, so that the blood bag device 10a is installed on the white filter system. After the installation of the blood bag device 10a is completed, the breaking unit 40 breaks the air inlet valve 111a on the blood bag 11a to allow gas to enter the interior of the blood bag 11a, so that the blood can enter the catheter 12a from the blood bag 11a, and then flow through the leukofiltration module 13a, and flow into the collecting bag 14a after leukofiltration by the leukofiltration module 13a. The blood filtered by the collecting bag 14a is collected to achieve blood leukofiltration. By breaking the breaking unit 40, the air inlet valve 111a on the blood bag 11a can be broken without manual work, which effectively reduces the manpower required for blood leukofiltration and speeds up the blood leukofiltration efficiency.

[0024] It can be understood that the hanging unit 20 can be any structure such as a hook, a hanging rod 51, etc., on which the blood bag 11a can be hung.

[0025] In one embodiment, if Figure 1-2 As shown, the hanging unit 20 includes a hanging rack 21 and an adjusting driving member 22. The hanging rack 21 is slidably connected to the top of the rack 10 along the height direction of the rack 10, and is used to hang the blood bag 11a. The adjusting driving member 22 is connected to the hanging rack 21, and is used to drive the hanging rack 21 to slide and adjust the height of the hanging rack 21. Specifically, before the white filter is performed, the blood bag 11a is hung by the hanging rack 21. After the hanging of the blood bag 11a is completed, the adjusting driving member 22 drives the hanging rack 21 to rise, and then the position of the blood bag 11a is adjusted to be higher, thereby accelerating the flow rate of blood and improving the white filter efficiency of blood.

[0026] In this embodiment, in order to facilitate the hanging of the blood bag 11a, in the early stage of hanging the blood bag 11a, the hanging rack 21 is at a height position adapted to the height of the human body.

[0027] It can be understood that the hanger 21 can be any structure such as a hook, a hanging rod 51, etc., on which the blood bag 11a can be hung.

[0028] In one embodiment, if Figure 1-3As shown, the hanger 21 includes a hanging support frame 211, a limiting member 212, a hanging member 213 and an elastic member 214. The hanging support frame 211 is slidably connected to the frame 10, the limiting member 212 is fixed to the hanging support frame 211, and is used to connect the limiting hole of the blood bag 11a. The hanging member 213 is slidably connected to the hanging support frame 211 and is opposite to the limiting member 212, and is used to hang the blood bag 11a. The two ends of the elastic member 214 are respectively connected to the hanging support frame 211 and the hanging member 213. Specifically, a socket is provided at the bottom of the blood bag 11a, and a hanging port is provided at the top of the blood bag 11a. When hanging the blood bag 11a, the blood bag 11a is first hung on the hanging piece 213 through the hanging port at the top, and then the elastic force of the elastic member 214 is overcome to pull the blood bag 11a in the direction of the limiting member 212, and then the blood bag 11a is hung on the limiting member 212 through the socket. The blood bag 11a is limited to complete the hanging of the blood bag 11a. By sliding the hanging member 213 and setting the elastic member 214, the hanger 21 can be adapted to the hanging of blood bags 11a of any size, and the blood bag 11a can be stabilized, thereby expanding the application scope of the white filtration system and improving the practical performance of the white filtration system.

[0029] In this embodiment, Figure 1-3 As shown, the suspension support frame 211 includes a horizontal mounting frame 2111 and a vertical frame 2112. The horizontal mounting frame 2111 is fixed to the frame 10 and extends in the width direction of the frame 10. The vertical frame 2112 is vertically fixed to the end of the horizontal mounting frame 2111 and extends in the height direction of the frame 10. The stopper 212 is fixed to the horizontal mounting frame 2111, and the hanging member 213 is slidably connected to the vertical frame 2112. Specifically, the horizontal mounting frame 2111 can realize the fixation of the suspension support frame 211 and the frame 10. The vertical frame 2112 can be provided with a sliding member to suspend the blood bag 11a. The vertical frame 2112 can be extended in the height direction of the frame 10, thereby adjusting the hanging height of the blood bag 11a to accelerate blood leukofiltration.

[0030] In this embodiment, Figure 1-3 As shown, the hanging member 213 includes a mounting block and a hook, the mounting block is slidably connected to the stand 2112, and the hook is fixed to the mounting block. Specifically, the mounting block can realize the sliding connection between the hanging member 213 and the stand 2112, and the hook can hang the blood bag 11a and limit the blood bag 11a to ensure the stability of the blood bag 11a.

[0031] It can be understood that the stand 2112 can be provided with structures such as slide rails or slide grooves for the hanging part 213 to slide.

[0032] In one embodiment, if Figure 1-3As shown, the stand 2112 is provided with a supply slide bar 2113, and the supply hanger 213 is sleeved on the supply slide bar 2113 and slidably connected to the supply slide bar 2113. Specifically, the supply hanger 213 can adjust the distance between the supply hanger 213 and the stopper 212 by sliding along the supply slide bar 2113, so as to adapt to the hanging of blood bags 11a of any size.

[0033] It can be understood that the elastic member 214 can be any elastic member with elastic properties such as a spring sheet, a rubber band, etc.

[0034] In one embodiment, if Figure 1-3 As shown, the elastic member 214 is a tension spring, one end of the elastic member 214 is fixed to the column, and the other end of the elastic member 214 is fixed to the supply hanger 213, and pulls the supply hanger 213. Specifically, the upward traction force of the tension spring on the supply hanger 213 can only tighten the suspended blood bag 11a, so that the suspended blood bag 11a remains stable.

[0035] It can be understood that the adjusting driving member 22 can be any driving component such as a cylinder, a hydraulic cylinder, etc. that can drive the bracket 21 to slide.

[0036] In one embodiment, if Figure 1-2 As shown, the adjustment drive member 22 includes a first motor 221 and a first screw rod 222. The first screw rod 222 is rotatably connected to the frame 10 and extends in the height direction of the frame 10. The first motor 221 is fixed to the frame 10 and connected to the first screw rod 222, and is used to drive the first screw rod 222 to rotate. The hanger 21 is threadedly connected to the first screw rod 222 through a screw nut. Specifically, when adjusting the height direction of the hanger 21, the first motor 221 drives the first screw rod 222 to rotate, which can drive the hanger 21 to move axially along the first screw rod 222, thereby realizing the adjustment of the height direction of the hanger 21 and ensuring the stability of the hanger 21 when sliding.

[0037] In one embodiment, if Figure 1-2 As shown, a first slide rail 11 is provided on the top of the rack 10, and the first slide rail 11 extends in the height direction of the rack 10. The hanger 21 is provided with a first slider 2114, and the hanger 21 is slidably connected to the first slide rail 11 through the first slider 2114. Specifically, the connection between the first slider 2114 and the first slide rail 11 can improve the stability between the hanger 21 and the rack 10, thereby ensuring the stable sliding of the hanger 21 along the height direction of the rack 10.

[0038] In one embodiment, if Figure 1-3As shown, the stopper 212 and the hanging member 213 are arranged at an angle with the width direction of the frame 10, so that the blood bag 11a can be hung obliquely relative to the frame 10. Specifically, by hanging the blood bag 11a obliquely, the space occupancy rate of the blood bag 11a can be effectively reduced, so that more blood bags 11a can be hung in a limited space, thereby filtering more blood at one time and accelerating the white blood filtration efficiency of the blood.

[0039] In this embodiment, Figure 1-3 As shown, the horizontal mounting frame 2111 fixes one end of the vertical frame 2112 and extends in the length direction of the frame 10, so that the horizontal mounting frame 2111 fixes one end of the vertical frame 2112 and can form an angle with the width direction of the frame 10, thereby enabling the limiter 212 and the vertical frame 2112 to form an angle with the width direction of the frame 10, and finally realizing the inclined suspension of the blood bag 11a.

[0040] In this embodiment, Figure 1-3 As shown, there are two limiters 212, and the hanging member 213 is disposed between the two limiters 212. Specifically, through this arrangement, shaking of the blood bag 11a can be avoided, and the stability of the blood bag 11a during the hanging process can be ensured.

[0041] In one embodiment, the hanging unit 20 further includes a first gravity sensor module (not shown in the figure), which is connected to the frame 10 and the hanger 21, and is electrically connected to the adjustment drive 22, and is used to sense the gravity of the hanger 21, so that the adjustment drive 22 drives the hanger 21 to rise after the blood bag 11a is hung. Specifically, the first gravity sensor sends a hanging gravity signal to the controller, and after the blood bag 11a is hung, the first gravity sensor senses the increase in gravity of the hanger 21, so that the controller controls the adjustment drive 22 to drive the hanger 21 to rise to the highest position, thereby accelerating the white filtration of the blood.

[0042] In this embodiment, as the blood flows out of the blood bag 11a, the gravity of the blood bag 11a will gradually decrease. When the first gravity sensor 45 detects that the gravity of the blood bag 11a is reduced to a certain value, the controller controls the adjustment drive 22 to drive the bag body support frame 31 to descend, and lower the collection bag 14a, thereby facilitating the staff to take out the empty blood bag 11a from the hanger 21, reducing the manpower consumed in the process of taking the blood bag 11a, and improving the efficiency of taking the bag.

[0043] In one embodiment, the hanging unit 20 further includes an identification module (not shown in the figure), which is installed on the frame 10 and electrically connected to the adjustment drive 22, and is used to identify the height of a human body. Specifically, the identification unit identifies the height of the staff member hanging the blood bag 11a, and then sends an identification signal to the controller, so that the controller controls the adjustment drive 22 to drive the hanger 21 to move to a suitable height, thereby facilitating the staff member to hang the blood bag 11a, reducing the manpower required to hang the blood bag 11a, and improving the hanging efficiency of the blood bag 11a.

[0044] It can be understood that the support unit 30 can be any structure that can support the collecting bag 14a, such as a support frame for supporting the collecting bag 14a, or a scraper frame for hanging the collecting bag 14a.

[0045] In one embodiment, if Figure 1 and 4 As shown, the support unit 30 includes a bag support frame 31 and a support adjustment member 32. The bag support frame 31 is slidably connected to the bottom of the frame 10 and is used to support the collection bag 14a. The support adjustment member 32 is connected to the bag support frame 31 and is used to drive the bag support frame 31 to slide and adjust the height of the bag support frame 31. Specifically, the bag support frame 31 can be used to place the collection bag 14a and provide support for the collection bag 14a. After the collection bag 14a is placed on the bag support frame 31, the support adjustment member 32 drives the bag support frame 31 to descend, thereby lowering the terrain of the collection bag 14a on the bag support frame 31 and increasing the distance between the collection bag 14a and the blood bag 11a, thereby accelerating the blood transportation speed and improving the white filtration efficiency.

[0046] In one embodiment, if Figure 1 and 4 As shown, the bag body support frame 31 is provided with a receiving cavity 311, and the upper side of the receiving cavity 311 is opened for receiving the collecting bag 14a. Specifically, the collecting bag 14a can be placed in the receiving cavity 311 through the upper side opening of the receiving cavity 311, thereby ensuring the stability of the collecting bag 14a and spacing it from the adjacent collecting bag 14a to avoid mutual interference during the white filter operation.

[0047] In one embodiment, if Figure 1 and 4As shown, the support unit 30 also includes a second gravity sensing module 50, which is fixed to the bag support frame 31 and electrically connected to the support adjustment member 32, and is used for the collection bag 14a to be suspended and sense the gravity of the collection bag 14a, so that when the collection bag 14a is suspended, the support adjustment member 32 drives the bag support frame 31 to descend. Specifically, after the collection bag 14a is suspended on the second gravity sensing module 50, the second gravity sensing module 50 senses the gravity of the collection bag 14a. After sensing the gravity of the collection bag 14a, the second gravity sensing module 50 transmits the sensed gravity signal to the controller, so that the controller controls the support adjustment member 32 to drive the bag support frame 31 to descend, thereby increasing the distance between the collection bag 14a and the blood bag 11a, and accelerating the white blood cell filtration.

[0048] In this embodiment, since the lengths of the catheters 12a of the blood bag devices 10a are not the same, under normal circumstances, after the installation of the collecting bag 14a is completed, the support adjustment member 32 drives the bag body support frame 31 to descend to the lowest level. However, compared with the blood bag devices 10a with relatively short catheters 12a, when the support adjustment member 32 controls the bag body support frame 31 to descend, if the second gravity sensor senses that the gravity of the collecting bag 14a is weakened, it means that the catheter 12a is already in a straightened state, and the collecting bag 14a cannot be further lowered. At this time, the controller controls the support adjustment member 32 to stop driving the bag body support frame 31, and finally lowers the collecting bag 14a as much as possible.

[0049] In this embodiment, after the blood flows into the collecting bag 14a, the gravity of the collecting bag 14a will gradually increase. When the second gravity sensor 45 detects that the gravity of the collecting bag 14a reaches a certain value, the controller controls the support adjustment member 32 to drive the bag body support frame 31 to rise, thereby raising the collecting bag 14a. As a result, the staff only needs to bend slightly to take out the collecting bag 14a filled with blood, thereby reducing the manpower consumed in taking out the bag and improving the efficiency of taking out the bag.

[0050] In this embodiment, Figure 1 and 4 As shown, the second gravity sensing module 50 is provided with a hanging rod 51. Specifically, the top of the collection bag 14a can be hung on the hanging rod 51 of the second sensing module, and the bottom of the collection bag 14a is supported by the bag body support frame 31, so as to achieve the stability of the collection bag 14a, facilitate the stability of the white filtering process, and facilitate the second gravity sensing module 50 to sense the gravity of the collection bag 14a.

[0051] It can be understood that the support adjustment member 32 can be any driving component such as a cylinder, a hydraulic cylinder, etc. that can drive the bag body support frame 31 to slide.

[0052] In one embodiment, if Figure 1 and 4As shown, the support adjustment member 32 includes a second motor 321 and a second screw rod 322. The second screw rod 322 is rotatably connected to the frame 10 and extends in the height direction of the frame 10. The second motor 321 is fixed to the frame 10 and connected to the second screw rod 322, and is used to drive the second screw rod 322 to rotate. The bag body support frame 31 is threadedly connected to the second screw rod 322 through a screw nut. Specifically, when adjusting the height direction of the bag body support frame 31, the second motor 321 drives the second screw rod 322 to rotate, which can drive the bag body support frame 31 to move axially along the second screw rod 322, thereby realizing the adjustment of the height direction of the bag body support frame 31 and ensuring the stability of the bag body support frame 31 when sliding.

[0053] In one embodiment, if Figure 1 and 4 As shown, the bottom of the rack 10 is provided with a second slide rail 12, the second slide rail 12 extends in the height direction of the rack 10, and the bag body support frame 31 is provided with a second slider 312, and the bag body support frame 31 is slidably connected to the second slide rail 12 through the second slider 312. Specifically, the connection between the second slider 312 and the second slide rail 12 can improve the stability between the bag body support frame 31 and the rack 10, thereby ensuring the stable sliding of the bag body support frame 31 along the height direction of the rack 10.

[0054] In one embodiment, if Figure 1 and 4 As shown, the frame 10 is also provided with a guide rod 13, which extends in the height direction of the frame 10, and the bag body support frame 31 is slidably connected to the guide rod 13. Specifically, the guide rod 13 can provide a limit and guide for the sliding of the bag body support frame 31, thereby improving the stability of the bag body support frame 31 when sliding.

[0055] In one embodiment, if Figure 1 and 4 As shown, the bag body support frame 31 is provided with a sliding frame 313 and a sliding sleeve 314, the sliding frame 313 is fixed to the bag body support frame 31, and the sliding sleeve 314 is fixed to the sliding frame 313 and sleeved with the guide rod 13. Specifically, the bag body support frame 31 can be slidably connected with the guide rod 13 through the sliding sleeve 314.

[0056] In one embodiment, if Figure 1 and 4 As shown, the bag body support frame 31 is further provided with a limiting frame 315, and the limiting frame 315 is sleeved on the guide rod 13. Specifically, the limiting frame 315 can further provide a limit for the bag body support frame 31, thereby improving the stability of the bag body support frame 31.

[0057] In this embodiment, the screw nut of the bag body support frame 31 is fixed to the limiting frame 315 .

[0058] It can be understood that the breaking unit 40 can be a driving member and a push rod, and the driving member drives the push rod to move toward the air inlet valve 111a of the blood bag 11a to break the air inlet valve 111a.

[0059] In one embodiment, if Figure 1-3 As shown, the breaking unit 40 includes a breaking piece 41 and a breaking drive module 42. The breaking piece 41 is rotatably connected to the bracket 21 and is used to connect the air inlet valve 111a of the blood bag 11a. The breaking drive module 42 is installed on the bracket 21 and is connected to the breaking drive module 42, and is used to drive the breaking drive module 42 to rotate so that the breaking drive module 42 breaks the air inlet valve 111a of the blood bag 11a. Specifically, after the blood bag 11a is hung on the hanger 21, the breaking drive module 42 drives the breaking piece 41 to rotate, so that the breaking piece 41 breaks the connected air intake valve 111a, thereby eliminating the need to manually break the air intake valve 111a, effectively reducing the manpower consumed in the breaking process of the air intake valve 111a, and achieving rapid breaking of the air intake valve 111a. After the air intake valve 111a is broken, the interior of the blood bag 11a can be connected to the external atmosphere through the valve port of the air intake valve 111a, so that the blood inside the blood bag 11a can flow out of the blood bag 11a, and the rapid breaking of the air intake valve 111a accelerates the white filtration of the blood.

[0060] It can be understood that the air intake valve 111a can be connected to the air intake valve 111a by providing a plug hole, and the breaking piece 41 is inserted into the plug hole of the air intake valve 111a, so that the breaking piece 41 can drive the air intake valve 111a to break by rotating.

[0061] In one embodiment, if Figure 1-3 As shown, the end of the breaking piece 41 is provided with a breaking opening 411, and the breaking opening 411 is provided for accommodating the air inlet valve 111a of the blood bag 11a. Specifically, when the blood bag 11a is suspended, the air inlet valve 111a of the blood bag 11a is installed in the breaking opening 411 of the breaking piece 41. After the blood bag 11a is suspended, the breaking driving module 42 drives the breaking piece 41 to rotate, so that the breaking piece 41 can break the air inlet valve 111a by rotating.

[0062] In this embodiment, Figure 1-3 As shown, a breaking head 412 is provided at the end of the breaking piece 41, and the breaking head 412 is detachably connected to the breaking piece 41, and the breaking opening 411 is provided at the breaking head 412. Specifically, by providing a detachable breaking head 412 at the end of the breaking piece 41, when breaking the intake valves 111a of different sizes, it is only necessary to adaptively replace the breaking head 412, so that the breaking unit 40 can adapt to the breaking of the intake valves 111a of any size, thereby improving the practical performance of the breaking unit 40.

[0063] In this embodiment, Figure 1-3 As shown, the breaking unit 40 further includes a locking bolt 43, the breaking head 412 is sleeved on the breaking piece 41, and the locking bolt 43 is threadedly connected to the breaking piece 41 and the breaking head 412 to lock the breaking head 412. Specifically, when replacing the breaking head 412, it is only necessary to disassemble the locking screw, and then remove the breaking head 412 from the breaking piece 41 and replace it.

[0064] In this embodiment, Figure 3 As shown, a positioning plane 413 is provided at the end of the breaking piece 41, and the positioning plane 413 is used to position the installation direction of the breaking head 412. Specifically, the positioning plane 413 positions the breaking head 412, and then the directions of the upper and lower sides of the breaking opening 411 can be positioned during the installation process, which provides convenience for the replacement of the breaking head 412.

[0065] In one embodiment, if Figure 3 As shown, the breaking unit 40 also includes a proximity switch 44 and a sensor 45. The sensor 45 is fixed to the breaking piece 41. The proximity switch 44 is fixed to the rack 21 and is close to the sensor 45, and is used to sense the sensor 45. When the proximity switch 44 senses the sensor 45, the breaking piece 41 breaks the air inlet valve 111a of the blood bag 11a. Specifically, during the process of breaking the air inlet valve 111a, the sensor 45 will gradually approach the proximity switch 44 through the rotation of the breaking piece 41. When the proximity switch 44 senses that the sensor 45 is approaching, it proves that the breaking piece 41 has broken the air inlet valve 111a of the blood bag 11a. At this time, the controller air breaking driver rotates in the opposite direction to drive the breaking piece 41 to reset. After the breaking piece 41 is reset, the breaking drive module 42 automatically stops working.

[0066] In this embodiment, the white filtering system is provided with a control button, and when the control button is pressed, the breaking driving module 42 is started.

[0067] It can be understood that the breaking drive module 42 can be any driving component such as a rotary cylinder or a motor that can drive the breaking piece 41 to rotate.

[0068] In one embodiment, if Figure 1-3 As shown, the breaking drive module 42 includes a breaking drive motor 421 and a transmission assembly 422. The breaking drive motor 421 is fixed to the rack 21. The transmission assembly 422 is connected to the breaking piece 41 and the shaft of the breaking drive motor 421, and is used to drive the breaking piece 41 to rotate by rotating the shaft of the breaking drive motor 421. Specifically, when the air intake valve 111a of the blood bag 11a is broken, the breaking drive motor 421 is started, and drives the breaking piece 41 through the transmission assembly 422 to achieve the breaking of the air intake valve 111a.

[0069] It can be understood that the transmission assembly 422 can be a transmission component such as a transmission gear, a transmission belt, etc. installed on the shaft of the breaking drive motor 421 and the breaking piece 41.

[0070] In one embodiment, if Figure 1-3 As shown, the transmission assembly 422 includes a transmission rod 4221, a first transmission gear (not marked in the figure) and a second transmission gear (not marked in the figure), the transmission rod 4221 is rotatably connected to the bracket 21 and is arranged in parallel with the breaking piece 41, the first transmission gear is fixed to the transmission rod 4221, the second transmission gear is fixed to the breaking piece 41 and meshes with the first transmission gear, and the breaking drive motor 421 is connected to the transmission rod 4221. Specifically, the breaking drive motor 421 drives the transmission rod 4221 to rotate, and then drives the breaking piece 41 to decelerate its rotation through the transmission of the first transmission gear and the second transmission gear, thereby increasing the driving force of the breaking drive module 42 acting on the breaking piece 41, so that the breaking piece 41 can smoothly break the intake valve 111a.

[0071] In this embodiment, the transmission rod 4221 extends axially. Specifically, through the axial extension of the transmission rod 4221, the transmission rod 4221 can be provided with a plurality of first transmission gears, which can then mesh with a plurality of second transmission gears on the breaking piece 41, thereby achieving stable driving of the breaking piece 41.

[0072] In this embodiment, Figure 1-3 As shown, a universal joint head 4222 is provided at one end of the transmission rod 4221 close to the breaking drive motor 421, and the transmission rod 4221 is hinged to the shaft of the breaking drive motor 421 through the universal joint head 4222. Specifically, through the hinge connection between the transmission rod 4221 and the shaft of the breaking drive motor 421, the transmission rod 4221 can form an angle with the shaft of the drive motor and can extend in any direction, so that the transmission rod 4221 can transmit the breaking piece 41 extending in any direction. Through this arrangement, the folding segment can be arranged in the form of an angle with the width direction of the frame 10, so that the folding segment can break the air intake valve 111a of the obliquely suspended blood bag 11a, and while satisfying the suspension of more blood bags 11a, the air intake valve 111a of each suspended blood bag 11a is automatically broken, thereby achieving the technical effect of accelerating blood leukofiltration.

[0073] In this embodiment, Figure 1 As shown, the blood bag device 10a further includes a bypass tube 15a. Both ends of the bypass tube 15a are connected to the conduit 12a and are connected in parallel to the leukofiltration module 13a. The bypass tube 15a can be used to exhaust the collection bag 14a.

[0074] In one embodiment, if Figure 1As shown, the white filtering system also includes a clamping unit 60, an exhaust unit 70 and a heat sealing unit 80. The clamping unit 60, the exhaust unit 70 and the heat sealing unit 80 are all installed on the frame 10. The clamping unit 60 is used to clamp the conduit 12a or the bypass pipe 15a, the exhaust unit 70 is used to exhaust the collection bag 14a, and the heat sealing unit 80 is used to heat seal the conduit 12a.

[0075] Specifically, when the blood is filtered, the clamping unit 60 clamps the bypass tube 15a to prevent the blood from bypassing the filter module 13a and flowing out from the bypass tube 15a into the collection bag 14a. When all the blood in the blood bag 11a passes through the filter module 13a and enters the collection bag 14a, due to the remaining air inside the collection bag 14a, the clamping unit 60 clamps the catheter 12a, and the exhaust unit 70 exhausts the gas in the collection bag 14a. The gas passes through the bypass tube 15a and enters the empty blood bag 11a, thereby exhausting the collection bag 14a and completing the collection bag. After the blood bag 14a is exhausted, the heat sealing unit 80 heat seals the catheter 12a connected to the collecting bag 14a to seal the collecting bag 14a. Finally, the catheter 12a is torn off from the heat sealing point to separate the collecting bag 14a from the blood bag device 10a. Through the cooperation of the clamping unit 60, the exhaust unit 70 and the heat sealing unit 80 of the leukofiltration system, the automatic exhaust and heat sealing of the leukofiltration system can be achieved, thereby eliminating the need to separately transport the blood bag device 10a to the exhaust device and the heat sealing device for exhaust and heat sealing, thereby reducing the manpower required for subsequent treatment of blood leukofiltration and improving the treatment efficiency of leukofiltration blood.

[0076] It can be understood that the clamping unit 60 can be a robot installed on the frame 10. The robot clamps the bypass pipe 15a when performing the white filter operation, and clamps the conduit 12a above the white filter module 13a when performing the exhaust operation of the collection bag 14a.

[0077] In one embodiment, if Figure 1 and 5 As shown, the clamping unit 60 includes a white filter clamping module 61 and an exhaust clamping module 62 of the same structure. Specifically, when performing white filter work, the white filter clamping module 61 clamps the bypass pipe 15a, and when performing exhaust work, the exhaust clamping module 62 clamps the conduit 12a above the white filter module 13a.

[0078] In this embodiment, Figure 1 and 5-6, the white filter clamping module 61 and the exhaust clamping module 62 both include a clamping frame 611, a clamping frame 612 and a clamping drive 613. The clamping frame 611 is fixedly connected to the frame 10, the clamping frame 612 is opposite to the clamping frame 611, and the clamping drive 613 is connected to the clamping frame 612 for driving the clamping frame 612 to move toward or away from the clamping frame 611. Specifically, the filter clamping module 61 and the exhaust clamping module 62 are arranged so that when the blood bag device 10a is suspended, the conduit 12a of the blood bag device 10a located above the filter module 13a is placed between the clamping frame 611 and the clamping frame 612 of the exhaust clamping module 62, and the bypass pipe 15a is placed between the clamping frame 611 and the clamping frame 612 of the filter clamping module 61. When the filter operation is performed, the clamping drive 613 of the filter clamping module 61 drives the clamping frame 612 to move toward the clamping frame 611, pressing the bypass pipe 15a against the clamping frame. The fixing frame 611 isolates the bypass pipe 15a to prevent blood from passing through the bypass pipe 15a. When the exhaust operation is performed, the clamping drive 613 of the filter clamping module 61 drives the clamping frame 612 to move away from the clamping fixing frame 611 to loosen the bypass pipe 15a. The clamping drive 613 of the exhaust clamping module 62 drives the clamping frame 612 to move toward the clamping fixing frame 611, so that the clamping frame 612 presses the catheter 12a to the clamping fixing frame 611, thereby isolating the catheter 12a, so that the air discharged from the collection bag 14a will pass through the bypass pipe 15a.

[0079] In this embodiment, Figure 1 and 6 As shown, an extrusion groove 6111 is provided on one side of the clamping frame 611 close to the clamping frame 612. The clamping frame 612 can press the conduit 12a or the bypass pipe 15a into the extrusion groove 6111 by moving toward the clamping frame 611, thereby effectively isolating the conduit 12a or the bypass pipe 15a.

[0080] In this embodiment, the clamping driving member 613 is a cylinder.

[0081] In this embodiment, the exhaust unit 70 is electrically connected to the first gravity sensing module. When the gravity sensed by the first gravity sensing module is lower than a certain value, the controller controls the exhaust unit 70 to exhaust the collection bag 14a. When the gravity value sensed by the first gravity sensing module increases during the exhaust process of the collection bag 14a, the controller controls the exhaust unit 70 to stop exhausting the collection bag 14a. Specifically, during the white filtering operation, the gravity of the blood bag 11a gradually decreases. When the gravity of the blood bag 11a decreases to a certain value, it means that the blood inside the blood bag 11a has been completely emptied. At this time, the exhaust unit 70 starts and starts to exhaust the collecting bag 14a. When the gravity value sensed by the first gravity sensing module increases, it means that some blood has entered the conduit 12a on the upper side of the filtering module, which means that all the air in the collecting bag 14a has been exhausted. Therefore, through the electrical connection with the first gravity sensing module, the collecting bag 14a can be automatically exhausted, which facilitates the exhaust operation of the collecting bag 14a, improves the exhaust efficiency of the collecting bag 14a, and thus speeds up the processing efficiency of the blood after white filtering.

[0082] In this embodiment, after the exhaust unit 70 completes the exhaust of the collection bag 14a, the white filter clamping module 61 and the exhaust clamping module 62 clamp the catheter 12a and the bypass tube 15a at the same time to prevent blood reflux.

[0083] In this embodiment, the exhaust unit 70 not only exhausts the collection bag 14a after the white filtration operation is completed, but also can exhaust the collection bag 14a at a fixed time during the white filtration operation to improve the white filtration efficiency of the blood.

[0084] It can be understood that the exhaust unit 70 can be a driver and a pressure plate. The driver can exhaust the collection bag 14a by driving the pressure plate to press the collection bag 14a toward the collection bag 14a, thereby squeezing the gas in the collection bag 14a out of the collection bag 14a.

[0085] In one embodiment, the exhaust unit 70 includes a peristaltic pump 71, which is electrically connected to the first gravity sensing module. The peristaltic pump 71 includes an upper cover, a shell, a driver, a chuck and a fixed block; the upper cover is provided with an opening, and the upper cover is arranged above the shell. There are at least three drivers, and the drivers are all arranged in the shell. Each driver is respectively provided with a push rod, and the driver can drive the push rod to move downward or upward, and the push rod passes through the shell and extends into the interior of the upper cover; the number of chucks and fixed blocks is the same as the number of drivers, and the chucks are respectively fixed on the push rods, and the fixed blocks are arranged in the upper cover and fixedly connected to the shell, and the chucks are pressed against the fixed blocks when they move downward. When the collecting bag 14a is being vented, the elastic conduit 12a is passed through the opening of the upper cover, and the conduit 12a is located between the chuck and the fixed block. When the driver drives the push rod to retract downward, the push rod drives the chuck to press the conduit 12a against the fixed block, and the conduit 12a is pressed and deformed. Since the volume of the deformed part is reduced, the blood or liquid medicine inside the deformed part of the conduit 12a is squeezed to both ends; if one end of the conduit 12a is in a cut-off state at this time, since the resistance of the air flowing in this direction is large, the air in the deformed part of the conduit 12a will flow in the direction of the other end; when the driver drives the push rod to extend upward, the push rod drives the chuck to loosen, and the conduit 12a returns to its original state under the action of its own elasticity. At this time, the space inside the conduit 12a becomes larger, forming a negative pressure, and then the conduit 12a in the collecting bag 14a is sucked into the conduit 12a. After the air is sucked into the conduit 12a, it will bypass the leukoplastic filter module 13a from the bypass pipe 15a, and enter the conduit 12a above the leukoplastic filter module 13a, and finally enter the blood bag 11a.

[0086] In one embodiment, if Figure 1 and 5 As shown, the leukofiltration system further includes a straightening unit 90, which is fixed to the frame 10 and is used to straighten the conduit located at the lower side of the leukofiltration module 13a. Specifically, since the lengths of the conduits 12a of the blood bag devices 10a are different, the conduits of some blood bag devices 10a located at the lower side of the leukofiltration module 13a are in a bent state. Therefore, before the heat sealing unit 80 performs heat sealing, the straightening unit 90 straightens the conduit 12a in a bent state, thereby facilitating the heat sealing unit 80 to heat seal the conduit 12a.

[0087] In this embodiment, the straightening unit 90 is electrically connected to the second gravity sensing module 50. During the straightening process of the catheter under the white filter module 13a, if the second gravity sensing module 50 senses a decrease in gravity, the controller controls the straightening unit 90 to stop straightening the catheter 12a. Specifically, if the second gravity sensing module 50 senses a decrease in gravity during the straightening process of the catheter under the white filter module 13a, it means that the catheter 12a has generated a pulling force acting on the collection bag 14a, indicating that the catheter 12a is in a straightened state. At this time, the heat sealing unit 80 is started to heat seal the straightened catheter 12a.

[0088] In this embodiment, after the collection bag 14a is exhausted, the straightening unit 90 is started, and after the catheter on the lower side of the white filter module 13a is straightened, the heat sealing unit 80 is started to heat seal the catheter 12a, thereby achieving automatic heat sealing of the catheter 12a, effectively reducing the manpower required for heat sealing of the catheter 12a, and improving the heat sealing efficiency of the catheter 12a.

[0089] It can be understood that the straightening unit 90 can clamp the catheter on the lower side of the white filter module 13a through a robot, and then pull the catheter 12a by sliding or rotating the robot upward to achieve straightening of the catheter 12a.

[0090] In one embodiment, if Figure 1 and 5 As shown, the straightening unit 90 includes a winding drive 91 and a winder 92. The winder 92 is used to connect the catheter 12a. The winding drive 91 is connected to the winder 92 and is used to drive the winder 92 to rotate so that the winder 92 winds the catheter 12a and straightens the catheter 12a. Specifically, when the catheter 12a is straightened, the winding drive 91 drives the winder 92 to rotate so that the winder 92 drives the catheter 12a to be wound around the winder 92, thereby achieving the straightening of the catheter on the lower side of the white filter module 13a.

[0091] In this embodiment, the winding driving component 91 is a motor, and the winding driving component 91 is electrically connected to the second gravity sensor module 50 .

[0092] In one embodiment, if Figure 1 and 5 As shown, the winder 92 is provided with a winding hole 921 with an opening on one side. When the blood bag device 10a is suspended, the catheter of the blood bag device 10a located at the lower side of the leukofiltration module 13a enters the winding hole 921 through the side opening of the winding hole 921, so that during the rotation of the winder 92, the catheter 12a can be driven to be wound, thereby achieving the straightening of the catheter 12a.

[0093] In one embodiment, if Figure 1 and 7As shown, the heat sealing unit 80 includes a segmented heat sealing drive 81 and a heat sealing module 82. The heat sealing module 82 is connected to the frame 10 by sliding along the height direction of the frame 10. The segmented heat sealing drive 81 is connected to the heat sealing module 82 and is used to drive the heat sealing module 82 to slide so that the heat sealing module 82 can perform multi-point heat sealing on the catheter 12a. Specifically, when performing the heat sealing work on the catheter on the lower side of the leukofiltration module 13a, the heat sealing module 82 can be driven by the segmented heat sealing drive member 81 to heat seal multiple points of the catheter 12a from bottom to top. After completing the heat sealing of each point of the catheter 12a, the catheter 12a can be disconnected through each heat sealing point. After the heat sealing point close to the collection bag 14a is disconnected, the collection bag 14a is sealed. After the other heat sealing points are disconnected, the catheter 12a can be divided into several sections of sub-tubes containing filtered blood. The blood in each sub-tube can be used as a sample for subsequent detection of the filtered blood. Therefore, through the automatic segmented heat sealing of the heat sealing unit 80, multi-segment sampling of the filtered blood can be achieved while sealing the collection bag 14a, which provides convenience for subsequent processing of the filtered blood.

[0094] It can be understood that the segmented heat sealing driving member 81 can be any driving component such as a cylinder, a hydraulic cylinder, etc. that can drive the heat sealing module 82 to rise and fall.

[0095] In one embodiment, if Figure 1 and 7 As shown, the segmented heat-sealing driving member 81 includes a third motor 811 and a third screw rod 812. The third screw rod 812 is rotatably connected to the frame 10 and extends in the height direction of the frame 10. The third motor 811 is fixed to the frame 10 and connected to the third screw rod 812, and is used to drive the third screw rod 812 to rotate. The heat-sealing module 82 is threadedly connected to the third screw rod 812 through a screw nut. Specifically, when performing segmented heat-sealing of the lower conduit 12a of the white filter module 13a, the heat-sealing module 82 first heat-seals the heat-sealing point close to the collection bag 14a. After completing the heat-sealing of the point, the third motor 811 drives the third screw rod 812 to rotate, which can drive the third screw rod 812 of the heat-sealing module 82 to move upward, and then the heat-sealing module 82 heat-seals the adjacent heat-sealing points above until all the heat-sealing points are completed.

[0096] In one embodiment, if Figure 1 and 7As shown in Figure 8, the heat-sealing module 82 includes a heat-sealing fixing frame 821, a heat-sealing driving member 822, a first heat supply block 823 and a second heat supply block 824. The first heat supply block 823 is fixed to the heat-sealing fixing frame 821. The second heat supply block 824 is arranged opposite to the first heat supply block 823 and forms a heat-sealing gap 825 with the first heat supply block 823. The heat-sealing driving member 822 is connected to the second heat supply block 824 and is used to drive the second heat supply block 824 to move toward or away from the first heat supply block 823. Specifically, when the blood bag device 10a is suspended, the catheter located at the lower side of the white filter module 13a is placed between the heat-sealing gaps 825. When the catheter 12a is heat-sealed, the heat-sealing driving member 822 drives the second heat supply block 824 to move toward the first heat supply block 823, so that the first heat supply block 823 and the second heat supply block 824 respectively heat-seal the catheter 12a on both sides of the catheter 12a, and finally complete the heat-sealing of the catheter 12a.

[0097] In one embodiment, if Figure 1 and 7 As shown in Figure 8, the heat sealing unit 80 further includes a guide head 83, which is fixed to the heat sealing fixing frame 821 and is located at the upper and lower sides of the heat sealing module 82. The guide head 83 is provided with a guide hole 831 with one side opening, and the guide hole 831 is in line with the heat sealing gap 825 for the conduit 12a to pass through. Specifically, the guide head 83 can provide guidance for the conduit 12a, and during the heat sealing work, limit the conduit 12a at the upper and lower sides of the heat sealing point of the conduit 12a, thereby improving the heat sealing quality of the conduit 12a.

[0098] In one embodiment, if Figure 1 and 7 As shown in Figure 8, the heat sealing unit 80 further includes a position sensor 84, which is fixed to the heat sealing fixing frame 821 and electrically connected to the third motor 811. Specifically, since the heat sealing unit 80 mainly performs heat sealing on the conduit 12a from bottom to top, after the exhaust of the collection bag 14a is completed, the third motor 811 drives the heat sealing module 82 to descend, and when the position sensor 84 senses the marked heat sealing position of the conduit 12a, the third motor 811 stops driving the heat sealing module 82, and the heat sealing module 82 starts to heat seal the conduit 12a from bottom to top.

[0099] In one embodiment, the white filter system further includes a drying unit (not shown in the figure), which is used to dry the surface of the conduit 12a before the heat sealing unit 80 performs the heat sealing operation on the conduit 12a. Specifically, since the temperature of the blood inside the blood bag 11a is relatively low when the blood bag 11a is taken out of the cold storage, the outer wall of the conduit is easily condensed to form water droplets. Therefore, in order to facilitate the heat sealing of the conduit 12a by the heat sealing unit 80, the conduit 12a is dried by the drying unit before the heat sealing unit 80 performs the heat sealing operation on the conduit 12a, which can facilitate the heat sealing of the heat sealing unit 80, thereby eliminating the need to wipe the outer wall of the conduit 12a before heat sealing, thereby facilitating the heat sealing operation of the conduit 12a.

[0100] The present invention also provides a whitening method, which is performed by a whitening system, such as Fig. 9 As shown, the following steps are included: The blood bag 11a is hung on the hanging unit 20, and the air inlet valve 111a of the blood bag 11a is connected to the breaking unit 40; The collection bag 14a is placed on the support unit 30; The breaking unit 40 breaks the air inlet valve 111a of the blood bag 11a; The blood in the blood bag 11a enters the catheter 12a, is filtered by the white filter module 13a, and then flows into the collection bag 14a and is collected by the collection bag 14a.

[0101] Specifically, by breaking the air inlet valve 111a in the blood bag 11a through the pre-white filtration breaking unit 40, the air inlet valve 111a on the blood bag 11a can be broken without manual work, which effectively reduces the manpower required for blood white filtration and can speed up the blood white filtration efficiency.

[0102] In one embodiment, before hanging the blood bag 11a on the hanging unit 20, the identification unit identifies the staff hanging the blood bag 11a, and the controller controls the adjustment drive member 22 to drive the hanger 21 to move to the head position of the staff, so as to facilitate the staff to hang, reduce the manpower required for hanging the blood bag 11a, and improve the hanging efficiency of the blood bag 11a.

[0103] In one embodiment, before the breaking unit 40 breaks the air inlet valve 111a of the blood bag 11a, the adjusting driving member 22 drives the hanger 21 to rise through the gravity signal of the first gravity sensing module, and after the collection bag 14a is placed on the supporting unit 30, the supporting adjusting member 32 drives the bag support frame 31 to descend through the gravity signal of the second gravity sensing module 50. Specifically, by the rising of the hanger 21 and the descending of the bag support frame 31, the distance between the blood bag 11a and the collection bag 14a can be effectively increased, thereby improving the white blood filtration efficiency.

[0104] In one embodiment, when the bag support frame 31 is lowered, if the second gravity sensor senses that the gravity of the collection bag 14a is weakened, the controller controls the support adjustment member 32 to stop driving the bag support frame 31. The collection bag 14a is adjusted as low as possible.

[0105] In one embodiment, after all the blood in the blood bag 11a is filtered out and enters the collection bag 14a, when the second gravity sensor 45 detects that the gravity of the collection bag 14a reaches a certain value, the controller controls the support adjustment member 32 to drive the bag body support frame 31 to rise, so that the staff can take out the collection bag 14a easily.

[0106] In one embodiment, after the leukofiltration of the blood is completed, subsequent treatment of the leukofiltration blood is performed.

[0107] In one embodiment, if Fig.10 As shown, the steps of processing blood after leukofiltration include: The clamping unit 60 clamps the conduit 12a and releases the clamping of the bypass pipe 15a; The exhaust unit 70 exhausts the gas in the collection bag 14a; The heat sealing unit 80 heat seals the collecting bag 14a.

[0108] Specifically, the automatic exhaust of the exhaust unit 70 and the automatic heat sealing of the heat sealing unit 80 can effectively reduce the manpower required for the blood treatment process after leukofiltration and improve the efficiency of the blood treatment after leukofiltration.

[0109] In one embodiment, in the step of the exhaust unit 70 exhausting the collection bag 14a, when the gravity sensed by the first gravity sensing module is lower than a certain value, the clamping unit 60 clamps the conduit 12a and releases the clamping of the bypass pipe 15a, and the controller controls the exhaust unit 70 to exhaust the collection bag 14a. When the gravity value sensed by the first gravity sensing module increases during the exhaust process of the collection bag 14a, the controller controls the exhaust unit 70 to stop exhausting the collection bag 14a, so as to realize automatic exhaust of the collection bag 14a.

[0110] In one embodiment, after the exhaust unit 70 completes the exhaust of the collection bag 14a, the straightening unit 90 straightens the conduit located at the lower side of the white filter module 13a, and during the straightening process, if the second gravity sensor module 50 senses a decrease in the gravity value, the controller controls the straightening unit 90 to stop straightening the conduit 12a. The straightening unit 90 automatically straightens the conduit, which facilitates the heat sealing unit 80 to heat seal.

[0111] In one of the embodiments, during the step of heat sealing the collection bag 14a by the heat sealing unit 80, the segmented heat sealing driving member 81 drives the heat sealing module 82 to gradually rise, so that the heat sealing is performed on multiple points of the catheter 12a from bottom to top, thereby achieving segmented heat sealing of the catheter 12a at the lower side of the leukofiltration module 13a, thereby facilitating the sampling and detection of blood after leukofiltration.

[0112] In one embodiment, before the heat sealing unit 80 performs the step of heat sealing the collecting bag 14 a , the drying unit dries the conduit 12 a between the collecting bag 14 a and the white filter module 13 a to facilitate the heat sealing of the heat sealing unit 80 .

[0113] In order to better understand the present invention, the following Figures 1 to 8 The technical solution of the present invention is described in detail: before performing blood leukofiltration, the first motor 221 drives the hanger 21 to move to a suitable height, so that the staff can hang the blood bag 11a on the hanger 213 and the limiter 212, the air inlet valve 111a of the blood bag 11a is installed in the broken opening 411 of the broken piece 41, and the conduit 12a is sequentially penetrated by the exhaust clamping module 62, the straightening unit 90 and the heat sealing unit 80. After the blood bag is suspended, the first motor 221 drives the hanger 21 to rise through the gravity sensed by the first gravity sensor module, and the bypass pipe 15a is penetrated. The white filter clamping module 61 and the second motor 321 drive the bag support frame 31 to rise to a certain height, and the collecting bag 14a is placed in the accommodating chamber 311. The second motor 321 drives the bag support frame 31 to descend through the gravity sensed by the second gravity sensor module 50, thereby completing the suspension of the blood bag device 10a. Through the automatic lifting and lowering adjustment of the hanging rack 21 and the bag support frame 31, the manpower required for the suspension of the blood bag 11a can be reduced, the suspension efficiency of the blood bag 11a can be accelerated, and the blood bag 11a and the collecting bag 14a can be kept as far away as possible during the white filter operation, thereby significantly improving the white filter efficiency.

[0114] After the hanger 21 rises and the bag support frame 31 descends, the white filter clamping module 61 clamps the bypass tube 15a to perform white filter work. During the white filter work, the breaking drive module 42 drives the breaking piece 41 to rotate, breaks the air inlet valve 111a, and the blood in the blood bag 11a enters the catheter 12a, and then flows through the white filter module 13a, and flows into the collecting bag 14a after white filter through the white filter module 13a, and the blood after white filter is collected by the collecting bag 14a, and finally the blood white filter is completed.

[0115] After completing the white filtration of the blood, the filtered blood is subsequently processed. During the processing, when the gravity sensed by the first gravity sensing module is lower than a certain value, the exhaust clamping module 62 of the exhaust unit 70 clamps the catheter 12a, and the white filtration clamping module 61 releases the clamping of the bypass pipe 15a. The controller controls the peristaltic pump 71 to exhaust the collection bag 14a. When the gravity value sensed by the first gravity sensing module during the exhaust process of the collection bag 14a increases, the exhaust of the collection bag 14a is completed. At this time, the winding drive 91 of the straightening unit 90 drives the winder 92 to rotate, so as to straighten the catheter located at the lower side of the white filtration module 13a, and the second gravity sensing module Block 50 senses that the gravity value decreases and the catheter 12a is straightened. At this time, the controller controls the winding drive 91 to stop winding. After the winding drive 91 stops, the segmented heat sealing drive 81 drives the heat sealing module 82 to gradually rise, so that the heat sealing is performed on multiple points of the catheter 12a from bottom to top, thereby realizing the segmented heat sealing of the catheter 12a on the lower side of the leukofiltration module 13a, which is convenient for sampling and testing of the blood after leukofiltration. The automatic exhaust of the collection bag 14a by the exhaust unit 70 and the heat sealing of the catheter 12a by the heat sealing unit 80 can realize automatic exhaust and heat sealing of the blood after leukofiltration, thereby reducing the manpower required for the blood processing process and accelerating the blood processing efficiency.

Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the protection scope of the claims of the present invention.
