Description

Technical Field

[0001] This invention belongs to the field of blood filtration technology, and more specifically, relates to a portable anti-clogging blood filtration integrated module and its usage method. Background Technology

[0002] Leukocytes in blood products easily lead to febrile nonhemolytic transfusion reaction (FNHTR), which is the most significant factor causing adverse transfusion reactions, accounting for approximately 52.1% of all adverse transfusion reactions. Leukocyte filtration (hereinafter referred to as "leukocyte filtration") can remove 99.9% of leukocytes from the blood, effectively preventing FNHTR. In practice, the demand for blood leukocyte filtration is high, but existing leukocyte filtration processes suffer from significant operational inconveniences, resulting in low efficiency. Therefore, this paper proposes a device that optimizes the blood leukocyte filtration process in terms of assembly efficiency and filtration effect, which is of great significance for blood product preparation.

[0003] To solve the above problems, the current working principle and process of the leukocyte filtration device (blood leukocyte filtration monitor) is as follows: after manually entering the blood donation code of the mother bag blood (whole blood before leukocyte filtration) into the system, it is suspended on the weighing hook of the leukocyte filtration monitor. The easy-break plug is opened to allow the blood to flow down, and the blood passes through the built-in white blood cell filter to remove white blood cells.

[0004] The above-mentioned method of using an existing multi-functional integrated white blood filter monitor to assist in white blood filtration simplifies the operation to a certain extent, but there are still the following technical problems or areas for improvement: (1) The operation process requires scanning the blood donation code, but the equipment currently on the market is all manual scanning and has not achieved automatic scanning, resulting in low operation efficiency. One reason is that one device has 24 to 40 workstations and the distance between adjacent workstations is relatively close; the second reason is that when white blood filtration is performed, the blood bag is hung vertically on the weighing hook, and the blood donation code label on the blood bag is easily blocked and not easily automatically identified; (2) The operation process requires breaking the easily broken plug to allow the blood to flow out of the pipeline. Currently, it is mainly done manually. Manual plug breaking has the disadvantages of low operation efficiency and high intensity; although there are automatic plug breaking devices applied to blood separation equipment, due to the difference in blood bag specifications, the automatic plug breaking position is difficult to determine accurately, and the blood bag position changes due to the synchronous reciprocating movement of the upper and lower plug breaking actuators, etc., the applicability of this device to the white blood filter monitor is not strong, and the plug breaking failure rate is high. Summary of the Invention

[0005] To address the aforementioned deficiencies or improvement needs of existing technologies, this invention provides a portable, anti-clogging integrated blood filtration module. By flipping the blood bag over so that the barcode faces the built-in scanner, it not only achieves automatic scanning, eliminating the tedious manual scanning operation, but also effectively avoids interference from adjacent blood bags, achieving one-to-one scanning. Furthermore, by setting a height adjustment mechanism to move the blood bag up and down, it solves the technical problem of difficulty in accurately installing easily broken stoppers into the stopper-breaking device due to different blood bag sizes. In addition, before the blood flows down for filtration, this invention controls the rotation and tilt of the blood bag, causing the blood clots inside the bag to shift to one side, preventing the technical problem of clot blockage during filtration, and greatly improving the success rate of blood bag filtration.

[0013] Preferably, the tilting bag anti-clogging unit includes:

[0014] A motor mounting slot is formed in the first-order side slot, and a tilting drive motor is fixed to the motor mounting slot in a direction perpendicular to the surface of the motor mounting slot. The output end of the tilting drive motor is fixedly connected to the center of the mounting base plate.

[0015] Preferably, the mother bag hanging assembly includes:

[0029] According to a second aspect of the present invention, a method of using a portable anti-clogging blood filtration integrated module includes the following steps:

[0030] S100: Insert the external positioning end into the bottom mounting port, and use the set screw as the clamping and positioning part to install and fix the external positioning end to this module, in preparation for performing the blood filtration task;

[0031] S200: Hang the mother bag with the barcode facing the window scanning port onto the hanging bag hook, and insert the blood catheter into the first limit card, the follow-up card and the second limit card. When the pressure sensor senses a stable pressure change, start the barcode scanner to scan the mother bag.

[0032] S300: Controls the rotation of the height adjustment drive motor, thereby driving the height adjustment drive screw to rotate, causing the hook connecting block to move downward, so that the mother bag moves downward slowly. When the mother bag moves down to the bottom of the bag and contacts the bag edge pressure sensor, the easy-break plug under the mother bag is inserted into the first limit card head and the follow-up card head, and the height adjustment drive motor is stopped through the signal feedback of the bag edge pressure sensor.

[0033] S400: Controls the tilting drive motor to rotate and tilt, so that the mounting base plate and the mother bag tilt together, causing the blood clots in the mother bag to be biased to one side of the mother bag, in order to prevent leakage and blockage during the whitening process.

[0034] S500: Controls the reciprocating rotation of the stopper drive motor, which in turn drives the stopper drive gear, transmission rack, and stopper driven gear in sequence, ultimately driving the stopper rotating block to reciprocate left and right to break the easily broken stopper and allow blood to flow down.

[0035] S600: When blood flows to the light rod probe, the light rod probe senses the blood flow and thus shuts off the plug drive motor;

[0036] S700: When the pressure sensed by the pressure sensor drops to the first preset value, it indicates that the main part of blood filtration in the mother bag has been completed. At this time, the tilting drive motor is controlled to rotate back to the center, so as to allow the residual blood in the bag to seep down as much as possible and prevent waste of blood resources.

[0037] S800: When the pressure sensed by the pressure sensor drops to the second preset value, it indicates that the blood filtration process in the blood bag is complete. At this time, the control adjusts the drive motor to rotate, lifting the mother bag and causing the easy-break stopper to disengage from the anti-shake stopper assembly. The staff can then remove the empty blood bag, thus completing one filtration task.

[0038] In summary, compared with the prior art, the above-described technical solutions conceived by this invention can achieve the following beneficial effects:

By flipping the blood bag over so that the barcode faces the built-in scanner, it not only achieves automatic scanning, eliminating the tedious manual scanning operation, but also effectively avoids interference from adjacent blood bags, achieving one-to-one scanning. Furthermore, by setting a height adjustment mechanism to move the blood bag up and down, it solves the technical problem of existing blood bags of different sizes making it difficult to accurately install easily broken stoppers into the stopper-breaking device. In addition, before the blood flows down for filtration, this invention controls the blood bag to rotate and tilt, causing the blood clots inside the bag to shift to one side, preventing the technical problem of clot blockage during filtration, and greatly improving the success rate of blood bag filtration.

[0071] A height-limiting sensing support rod fixed to the upper surface of the side base block 421, and a bag edge pressure sensor 422 disposed on the upper surface of the height-limiting sensing support rod.

[0072] like Figure 2 As shown, in this embodiment of the invention, the anti-shake plug assembly 430 includes:

[0073] A first limiting head 432 is fixedly disposed in the middle gap of the pair of side base blocks 421, a prying block 433 is disposed close to the bottom of the first limiting head 432, a follower head 4331 is fixedly disposed on the upper surface of the prying block 433, and a prying drive assembly 434 drives the prying block 433 to reciprocate.

[0080] like Figures 6-11As shown, the working principle of this invention is as follows: First, the external positioning end is inserted into the bottom mounting port 101, and the external positioning end is fixed to the module using a set screw as the clamping positioning part 102, in preparation for performing the blood filtration task; then, the mother bag holding the barcode is hung on the hanging bag hook 412 with the window scanning port 451 facing the direction, and the blood catheter is inserted into the first limiting head 432, the follower head 4331 and the second limiting head 441. When the pressure sensor 501 senses a stable pressure change, the barcode scanner 452 is started to scan the mother bag. Next, the height adjustment drive motor 4131 is controlled to rotate, thereby driving the height adjustment drive screw 4132 to rotate, causing the hook connecting block 411 to move downward, so that the mother bag moves downward slowly. When the mother bag moves down to the bottom of the bag and contacts the bag edge pressure sensor 422, the easy-break plug at the bottom of the mother bag is inserted into the first limit clip 432 and the follower clip 4331, and the height adjustment drive motor 4131 is stopped by the signal feedback from the bag edge pressure sensor 422. Then, the tilting drive motor 301 is controlled to rotate and tilt, so that the mounting base plate 400 and the mother bag move together. The system tilts together, causing the blood clots in the mother bag to shift to one side, preventing leakage and blockage during the filtration process. Next, the stopper-opening drive motor 4341 reciprocates, sequentially driving the stopper-opening drive gear 4342, transmission rack 4343, and stopper-opening driven gear 4345, ultimately causing the stopper-opening block to reciprocate left and right to open the easily broken stopper, allowing blood to flow. Then, when the blood reaches the light rod probe, it senses the blood flow and shuts off the stopper-opening drive motor 4341. Following this, the pressure sensor... When the pressure sensed by pressure sensor 501 drops to the first preset value, it indicates that the main part of blood filtration in the mother bag has been completed. At this time, the tilting drive motor 301 is controlled to rotate back to the center, so as to allow the residual blood in the bag to seep down as much as possible and prevent blood resources from being wasted. When the pressure sensed by pressure sensor 501 drops to the second preset value, it indicates that the blood filtration in the blood bag has been completed. At this time, the lifting drive motor 4131 is controlled to rotate, lifting the mother bag and causing the easy-break stopper to disengage from the anti-shake stopper assembly 430. The staff can then remove the empty blood bag, thus completing one filtration task.

[0081] In this embodiment of the invention, by flipping the blood bag over so that the barcode faces the built-in scanner, automatic scanning is achieved, eliminating the tedious manual scanning operation. This also effectively avoids interference from adjacent blood bags, enabling one-to-one scanning. Furthermore, by setting a height adjustment mechanism to move the blood bag up and down, the technical problem of difficulty in accurately installing easily broken stoppers onto the stopper-breaking device due to different blood bag sizes is solved. Additionally, before the blood bleaching process, the invention controls the rotation and tilt of the blood bag, causing the blood clots inside to shift to one side, preventing clot blockage during bleaching and greatly improving the success rate of blood bag bleaching.

[0082] In this embodiment of the invention, by adopting the design concept of "fixed top and moving bottom", a first limiting card head and a stopper-breaking rotating block are set up. By controlling the rotation of the stopper-breaking rotating block, the operation of breaking the easily broken stopper can be effectively completed. At the same time, under the limiting action of the first limiting card head in the stationary state, the technical problem of the traditional stopper-breaking device being broken both up and down, causing the upper blood bag to swing, is avoided, thus improving the stability of the whitening process.

10. A method of using a portable, anti-clogging integrated blood filtration module, characterized in that, Includes the following steps: S100: Insert the external positioning end into the bottom mounting port (101), and use the set screw as the clamping positioning part (102) to install and fix the external positioning end to this module, in preparation for performing the blood filtration task; S200: Hang the mother bag with the barcode facing the window scanning port (451) on the hanging bag hook (412), and insert the blood catheter into the first limit card head (432), the follow-up card head (4331) and the second limit card head (441). When the pressure sensor (501) senses a stable pressure change, start the barcode scanner (452) to scan the mother bag. S300: Control the height adjustment drive motor (4131) to rotate, thereby driving the height adjustment drive screw (4132) to rotate, causing the hook connecting block (411) to move downward, so that the mother bag moves downward slowly. When the mother bag moves down to the bottom of the bag and contacts the bag edge pressure sensor (422), the easy-break plug under the mother bag is inserted into the first limit card head (432) and the follower card head (4331), and the height adjustment drive motor (4131) is stopped by the signal feedback from the bag edge pressure sensor (422). S400: Control the tilting drive motor (301) to rotate and tilt, so that the mounting base plate (400) and the mother bag tilt together, so that the blood clot in the mother bag is biased to one side of the mother bag, in order to prevent leakage and blockage during the whitening process. S500: Controls the reciprocating rotation of the plug-opening drive motor (4341), thereby sequentially driving the plug-opening drive gear (4342), transmission rack (4343), and plug-opening driven gear (4345) to drive the plug-opening rotating block to reciprocate left and right, so as to open the easily broken plug and allow blood to flow down. S600: When blood flows to the light rod probe, the light rod probe senses the blood flow and thus shuts off the plug drive motor (4341); S700: When the pressure sensed by the pressure sensor (501) drops to the first preset value, it indicates that the main part of blood filtration in the mother bag has been completed. At this time, the tilting drive motor (301) is controlled to rotate back to the center, so as to allow the residual blood in the bag to seep down as much as possible and prevent waste of blood resources. S800: When the pressure sensed by the pressure sensor (501) drops to the second preset value, it indicates that the blood filtration work in the blood bag is completed. At this time, the control adjusts the drive motor (4131) to rotate, lifts the mother bag, and makes the easy-break plug disengage from the anti-shake plug-breaking assembly (430). The staff takes out the empty blood bag, thus completing one filtration task.
