Abstract
Description
Technical Field
[0001] This invention relates to blood sterilization and treatment technology, specifically to an ultraviolet swing-type blood processor suitable for blood bags. Background Technology
[0002] Blood bags are disposable biomedical transparent flexible polyvinyl chloride (PVC) containers designed to collect, process, store, transfer, separate, and transfuse whole blood and blood components. The blood bag system consists of a blood bag, a donor tube (consisting of a needle with a cap), a blood bag braid, a puncturable and non-sealable transfusion canister, and clamps. Currently, after blood collection, blood bags are placed in blood bag processing equipment and subjected to continuous ultraviolet irradiation treatment using an irradiation device to kill pathogens and bacteria in the blood bag, while reducing the risk of transfusion-related complications in later transfusions.
[0003] Blood irradiation devices, as specialized medical equipment used to irradiate blood, work by using high-energy gamma rays or X-rays to inactivate immune-active T lymphocytes in the blood, but have little effect on the function of red blood cells, platelets, and the activity of coagulation factors.
[0004] To ensure the effectiveness and adequacy of blood bag irradiation, a shaking device is typically used to agitate the blood bags during the irradiation process. This ensures that ultraviolet light reaches all parts of the blood, effectively inactivating any pathogens present. Shaking the blood bag also helps to evenly mix the blood components, preventing any areas from being under-irradiated. This ensures that the entire bag of blood is exposed to ultraviolet light, thus improving sterilization efficiency. Furthermore, shaking the blood bag helps to remove air bubbles, distributing the blood more evenly within the bag for uniform irradiation.
[0005] When using existing ultraviolet swing-type blood processing devices, it becomes difficult to maintain continuous irradiation of all blood bags while shaking them to the same degree when the number of blood bags increases. Currently, most blood bags on the market are arranged in an array for simultaneous irradiation. However, the shaking of blood bags in an array is centered on the central axis of the array. This results in blood bags further away from the axis shaking much more than those closer to the axis, leading to inconsistent shaking and irradiation levels. Summary of the Invention
[0006] The purpose of this invention is to provide an ultraviolet swing-type blood processing device suitable for blood bags, so as to overcome the above-mentioned shortcomings of the prior art.

[0026] Furthermore, the irradiation detection assembly includes a translation drive component 2 fixedly installed on the side of the partition 1 away from the swaying frame assembly. The output end of the translation drive component 2 is fixedly installed with a drive shaft 3, and one end of the drive shaft 3 slides through the partition 1 and is fixedly installed with a detection component.
[0027] A control cabinet is fixedly installed on one side of the main unit, and a touch screen is fixedly installed on one side of the control cabinet.
[0028] Compared with the prior art, the present invention provides an ultraviolet swing-type blood processing device suitable for blood bags. By setting a turntable and distributing several blood bag fixing components in a circular array on it, it solves the problem that when the number of blood bags increases, it is difficult to maintain continuous irradiation treatment on all blood bags while shaking multiple blood bags to the same degree. At the same time, it avoids the situation in the current market where multiple blood bags are distributed in an array and shaken with the central axis of the array as the center, resulting in blood bags far from the axis shaking much more than blood bags close to the axis shaking, which further leads to uneven shaking degree and uneven irradiation degree of blood bags.
[0029] This ultraviolet swing-type blood processor for blood bags uses a rotary drive component to intermittently rotate a drive shaft and gear one, which in turn meshes with gear two and a sleeve to intermittently rotate. The sleeve's rotation, in conjunction with bevel gear one, drives bevel gear two and a turntable to intermittently rotate. This allows medical personnel to sequentially place blood bags onto the blood bag fixing assembly for secure placement, avoiding the problem of difficulty in placing blood bags individually in designated positions when the door is narrow or the main unit has limited space. Simultaneously, the rotary drive component two, in conjunction with drive shaft two, rotates the rotating plate. In conjunction with the connecting rod, the power rod and the L-shaped folding rod are driven to reciprocate and rotate. The L-shaped folding rod drives the second bevel gear and the turntable to reciprocate and rotate. At the same time, the second bevel gear rotates and meshes with the first bevel gear, so that the turntable and the second bevel gear reciprocate and rotate around the axis of the turntable. This ensures that the blood bags on the blood bag fixing assembly are shaken sufficiently, while switching the shaking position of each blood bag during the shaking process, so as to continuously adjust the shaking degree of the blood bags on each blood bag fixing assembly. At the same time, the first bevel gear is further utilized to reduce the setting of internal mechanical structure, simplify the device structure, and reduce maintenance costs.
[0030] This UV-Vibrating Swing Blood Processor for Blood Bags uses a translational drive to retract a movable rod, which in turn retracts a push plate. The elastic element releases its tension and retracts a longitudinal rod, causing it to reposition and translate. The two longitudinal rods then converge to gather the blood bag's ferrule and donor tube. Simultaneously, as the longitudinal rods converge, a fixing pin causes a protrusion to rotate eccentrically. Once the longitudinal rods reach their near-limit distance, the eccentrically rotated protrusion abuts against a downward-moving U-shaped frame. This downward movement of the U-shaped frame, in conjunction with a sliding frame, further gathers the blood bag. The blood bag's braid and the donor tube are pressed down and fixed, which not only achieves the first binding and then pressing and fixing of the tube, improving the convenience and ease of tube binding, but also prevents the longitudinal rod from descending and doing work on the tube when binding the tube, thus avoiding the situation where the tube is pulled hard during binding. This avoids the situation where the tube is pulled and deformed or the connection between the tube and the blood bag is broken, which is caused by the traditional method of using elastic elements to adjust the pressing of the tube while binding the tube.

A door is rotatably mounted on the front of the main unit housing 1. A switch transmission signal device is installed inside the main unit housing 1 near the door. When medical personnel open the door, the switch transmission signal device detects the door moving away and transmits a signal to the control cabinet 7. The control cabinet 7 then activates a rotation drive 81 until a light shield 85 completely closes the irradiation port. The device also includes:
[0068] Irradiation assembly 2, which is installed inside the upper part of the main unit housing 1;
[0069] The swaying frame assembly 3 is installed below the irradiation assembly 2 and can limit and fix the blood bags. The irradiation assembly 2 can irradiate all the blood bags on the swaying frame assembly 3.

The L-shaped folding rod 10 rotates back and forth around the long axis and drives the second bevel gear 14 and the turntable 31 to rotate back and forth. At the same time, the second bevel gear 14 rotates and meshes with the first bevel gear 13, so that the turntable 31 and the second bevel gear 14 rotate back and forth around the axis of the turntable 31, so as to fully shake the blood bags on the blood bag fixing assembly 32, and continuously adjust the degree of shaking of the blood bags on each blood bag fixing assembly 32.

The end of the L-shaped folding rod 10 away from the drive component 5 is connected to the inner cavity of the main unit box 1 through a connecting seat. The connecting seat provides support for the end of the L-shaped folding rod 10.
[0076] Medical staff can activate the rotary drive component 51. The rotary drive component 51 drives the drive shaft 1 and gear 1 52 to rotate intermittently and mesh with gear 2 53 and sleeve 11 to rotate intermittently. The rotation of sleeve 11, in conjunction with bevel gear 1 13, drives bevel gear 2 14 and turntable 31 to rotate intermittently. At this time, the power component 2 is not activated, which can provide fixed support for the L-shaped folding rod 10. As the turntable 31 rotates, medical staff can place blood bags on the blood bag fixing component 32 for limiting and fixing. The outer side of the L-shaped folding rod 10 is rotatably mounted with bevel gear 2 14 which is fixedly connected to the bottom of the turntable 31. The outer side of the sleeve 11 is fixedly mounted with bevel gear 13 which meshes with bevel gear 2 14.

The output end of the rotary drive component 51 is fixedly installed with a drive shaft 52 via a coupling. A gear 52 is fixedly installed on the outside of the drive shaft 52. A gear 53 that meshes with the gear 52 is fixedly installed on the outside of the sleeve 11.
[0079] The second power component includes a second rotary drive component 54 fixedly installed on one side of the partition. The second rotary drive component 54 may also include, but is not limited to, a stepper motor or a servo motor. The second rotary drive component 54 is electrically connected to an external power supply and is controlled by an external PLC programming program. The output end of the second rotary drive component 54 is fixedly installed with a second drive shaft via a coupling. A rotating plate 55 is fixedly installed at one end of the second drive shaft. A connecting rod 56 is rotatably installed on one side of the rotating plate 55. A power rod 57, which is rotatably connected to the end of the connecting rod 56, is fixedly installed on the outer side of the L-shaped folding rod 10.
[0080] Since conventional blood bags typically have a blood bag loop and a donor tube, the shaking during irradiation can cause these loops and tubes to swing and even become entangled. To prevent damage or entanglement caused by excessive shaking, this technical solution uses a limiting and fixing method for the tubes. However, since the blood bag fixing components 32 are arranged in a ring array on top of the turntable 31, the orientation of the blood bag loop and donor tube is limited to either inward or outward. When the loop and donor tube are placed outward, although medical staff can easily manually gather and fix them by rotating the turntable 31, the resulting loop may not be properly secured. The blood bag braid and donor tube still need to be fixed to the turntable 31. However, to provide a fixed support point for the gathered blood bag braid and donor tube, the volume of the turntable 31 needs to be further increased. Simultaneously, with the increase in the size of the turntable 31, the blood bag braid and donor tube fixed on the outer side need to withstand greater inertial or centrifugal forces. Placing the fixing points of the blood bag braid and donor tube on the inner side firstly further utilizes the unused space in the center of the turntable 31, and secondly, the inertial force experienced by the blood bag braid and donor tube placed on the inner side will be greatly reduced. However, placing the blood bag braid and donor tube on the inner side undoubtedly increases the difficulty for medical personnel in gathering them. To overcome this technical difficulty, this application proposes the following solution: [The solution also includes...] Several bundle tube assemblies 9 are mounted on the turntable 31. Each bundle tube assembly 9 includes a sliding frame 91. Two symmetrically arranged longitudinal rods 92 are slidably mounted laterally on the inner wall of the sliding frame 91. The bottom of the two longitudinal rods 92 on opposite sides, near the push plate 99, is provided with an inclined surface. A U-shaped frame 93 is slidably mounted vertically on the opposite side of the two longitudinal rods 92. A spring (not shown in the figure) is fixedly installed between the U-shaped frame 93 and the longitudinal rods 92 to realize the automatic upward reset of the U-shaped frame 93 when the protrusion 97 does not press against the U-shaped frame 93. A rotating shaft 94 is rotatably mounted inside the sliding frame 91. Two inclined grooves 95 are symmetrically opened on the outer side of the rotating shaft 94. Fixing pins 96 that are slidably connected to the inner walls of the two inclined grooves 95 are fixedly installed inside the two longitudinal rods 92 respectively. Two protrusions 97 are fixedly installed on the outer side, respectively abutting against the bottom of the inner part of the two C-shaped frames 93. Two elastic elements 98 are symmetrically sleeved on the outer side of the rotating shaft 94. The elastic elements 98 include, but are not limited to, springs. The elastic elements 98 are fixedly connected to the inner side of the sliding frame 91 and the outer side of the longitudinal rod 92, respectively. A translation drive component 58 is fixedly installed on the side of the partition plate one near the power component two. The translation drive component 58 includes, but is not limited to, an electric telescopic rod or a hydraulic rod. The translation drive component 58 is electrically connected to an external power supply and is controlled by an external PLC programming program. A movable rod 12 connected to the inner wall of the L-shaped folding rod 10 is fixedly installed at the output end of the translation drive component 58. A push plate 99 that can abut against the bottom of one side of the two longitudinal rods 92 is fixedly installed at one end of the movable rod 12.The cross-section of the push plate 99 is an isosceles triangle, meaning that two inclined surfaces are symmetrically arranged on the side of the push plate 99 away from the movable rod 12, and these inclined surfaces are adapted to the inclined surface at the bottom of one side of the longitudinal rod 92.
[0081] As the turntable 31 rotates intermittently, the control cabinet 7 activates the translation drive 58. The translation drive 58 can be activated when the turntable 31 stops rotating and pushes out the movable rod 12. After the movable rod 12 extends, it cooperates with the push plate 99 to push the two longitudinal rods 92 along the inner wall of the sliding frame 91 and move them away from each other. At this time, the elastic element 98 contracts under force, and the longitudinal rods 92 cooperate with the fixing pins 96 to slide along the inclined groove 95, thereby driving the rotating shaft 94 and the protrusion 97 to rotate. The eccentric rotation of the protrusion 97 releases its contact with the bottom of the U-shaped frame 93, thus releasing the downward pressure on the U-shaped frame 93. When placing blood bags, medical personnel can place the blood bag's braid and donor tube between the U-shaped frame 93 and the sliding frame 91. Just before the turntable 31 is about to rotate again, the translation drive 58 drives the movable rod 12 to retract, and the movable rod 12 drives the push plate 99 to advance. When the blood bag is reset and retracted, the elastic element 98 is released from the force and drives the longitudinal rod 92 to reset and move. The two longitudinal rods 92 move closer to each other to concentrate and gather the blood bag braid and donor tube of the blood bag. At the same time, when the longitudinal rods 92 move closer to each other, they cooperate with the fixing pin 96 to drive the protrusion 97 to rotate eccentrically until the longitudinal rod 92 moves to the near limit distance. Then, the protrusion 97 rotates eccentrically and abuts against the U-shaped frame 93 and moves down. The U-shaped frame 93 moves down and can cooperate with the sliding frame 91 to press down and fix the blood bag braid and donor tube of the blood bag during the gathering. This process is repeated. The tube assembly 9 also includes a through groove 1 that is opened through the top of the turntable 31 and located on the side of each blood bag fixing assembly 32 near the bevel gear 14. The inner wall of the through groove 1 is horizontally slidably connected to the sliding frame 91. The two U-shaped frames 93 are also symmetrically arranged. A through groove 2 that is connected to the rotating shaft 94 is opened through one side of the U-shaped frame 93.
[0082] It also includes a gate assembly 8, which includes a rotary drive component 81 fixedly mounted on the top of the partition 2. The rotary drive component 81 includes, but is not limited to, a stepper motor or a servo motor. The rotary drive component 81 is electrically connected to an external power supply and is controlled by an external PLC programming program. A threaded rod 82 is fixedly mounted on the output end of the rotary drive component 81 via a coupling. A support base 83 rotatably connected to the outside of the threaded rod 82 is also fixedly mounted on the top of the partition 2. A threaded frame 84 threadedly connected to the outside of the threaded rod 82 is slidably mounted on the top of the support base 83. A light shield 85 is fixedly mounted on the side of the threaded frame 84 near the irradiation assembly 2. A cover box 86 is fixedly mounted on the top of the partition 2. An irradiation port is provided through the enclosure 86, and the irradiation port penetrates the enclosure 86. The area of the irradiation port is smaller than the cross-sectional area of the light shield 85. The light shield 85 slides through the enclosure 86 on one side and extends into the interior of the enclosure 86. At least two position sensors 87 arranged in an array are fixedly installed on the top of the partition plate 2 and on the side of the support base 83 away from the enclosure 86. The rotary drive component 3 81 can drive the threaded rod 82 to rotate and drive the threaded frame 84 to move laterally. At the same time, the position sensor 87 can monitor the translation limit distance of the threaded frame 84. When the position sensor 87 detects that the threaded frame 84 is close, it shuts down the rotary drive component 3 81 through the controller in the control cabinet 7.
[0083] The irradiation assembly 2 includes a shroud 21 fixedly mounted on the top of the enclosure box 86. Lamp holders 22 are fixedly mounted on both sides of the shroud 21, and a lamp tube 23 is fixedly mounted inside the shroud 21. The lamp tube 23 includes, but is not limited to, a mercury lamp. A heat sink 24 is fixedly mounted on the top of the shroud 21 above the lamp tube 23. The heat sink 24 includes, but is not limited to, metal heat sink fins. The heat sink 24 is common knowledge in the art and only needs to have the property of dissipating the heat when the lamp tube 23 is working. It will not be described in detail here. A reflector 25 is fixedly mounted inside the shroud 21 on one side above the lamp tube 23. A terminal block 26 is fixedly mounted on the top of each of the two lamp holders 22.
[0084] The translation drive component 2 41 is activated and pushes the detection component 42 out through the drive shaft 3 to detect the irradiation intensity of the lamp tube 23. After the detection is completed, the translation drive component 2 41, in conjunction with the drive shaft 3, drives the detection component 42 to retract. When the detected irradiation intensity is confirmed to be qualified, the medical staff can open the door of the main unit box 1. The irradiation detection component 4 includes the translation drive component 2 41, which is fixedly installed on the side of the partition 1 away from the swaying frame component 3. The translation drive component 2 41 includes, but is not limited to, an electric telescopic rod or a hydraulic rod. The translation drive component 2 41 is electrically connected to an external power supply and is controlled by an external PLC programming program. The output end of the translation drive component 2 41 is fixedly installed with the drive shaft 3, and one end of the drive shaft 3 slides through the partition 1 and is fixedly installed with the detection component 42. The detection component 42 includes, but is not limited to, an ultraviolet intensity detector, and the detection component 42 is electrically connected to an external power supply.
[0085] Medical staff turn on the lamp 23 in the irradiation component 2 via the touch screen 6. The lamp 23 is preheated for 10 to 20 minutes. Then, the irradiation detection component 4 is turned on via the touch screen 6. A control cabinet 7 is fixedly installed on one side of the main unit 1, and a touch screen 6 is fixedly installed on one side of the control cabinet 7.
[0086] At the same time, a temperature sensor was added to detect the temperature of the cavity inside the main unit 1 and below the partition 2. When the temperature inside the cavity exceeds 38°C, the lamp tube 23 is turned off and the irradiation port gate assembly 8 is closed.
[0087] The exterior parts are manufactured using laser cutting and sheet metal bending processes. The fastening method involves internal bolt fastening, making the bolts invisible from the outside. All mechanical parts are modularly designed, simplifying equipment maintenance and upkeep. When cleaning the equipment, protruding parts are minimized to avoid dead corners during manual cleaning, further facilitating manual cleaning.
[0088] Working principle: In use, medical staff first turn on the lamp 23 in the irradiation assembly 2 via the touch screen 6. The lamp 23 preheats for 10-20 minutes. Then, the irradiation detection assembly 4 is turned on via the touch screen 6. The translation drive 41 is activated and pushes the detection element 42 out through the drive shaft 3 to detect the irradiation intensity of the lamp 23. After the detection is completed, the translation drive 41, in conjunction with the drive shaft 3, drives the detection element 42 to retract. Once the detected irradiation intensity is confirmed to be qualified, the medical staff can open the door of the main unit 1. When the door is opened, the door moves away from the switch to transmit signals. The device, control cabinet 7, starts the gate assembly 8 to close the irradiation port. Medical staff then start the rotary drive component 51. The rotary drive component 51 starts and drives the drive shaft 1 and gear 1 52 to rotate intermittently and meshes with gear 2 53 and sleeve 11 to rotate intermittently. The rotation of sleeve 11, in conjunction with bevel gear 1 13, meshes with bevel gear 2 14 and turntable 31 to rotate intermittently. At this time, the power component 2 is not started, so it can provide fixed support for the L-shaped folding rod 10. As the turntable 31 rotates, medical staff can place the blood bags on the blood bag fixing assembly 32 in sequence for limiting and fixing.
[0089] Simultaneously, as the turntable 31 intermittently rotates, the control cabinet 7 activates the translation drive component 58. The translation drive component 58 can be activated when the turntable 31 stops rotating and pushes out the movable rod 12. After the movable rod 12 extends, it cooperates with the push plate 99 to push the two longitudinal rods 92 to slide along the inner wall of the sliding frame 91 and move away from each other. At this time, the elastic element 98 is compressed by force, and the longitudinal rods 92 cooperate with the fixing pins 96 to slide along the inclined groove 95, so as to drive the rotating shaft 94 and the protrusion 97 to rotate. The eccentric rotation of the protrusion 97 releases the contact with the bottom of the U-shaped frame 93, so that the U-shaped frame 93 releases the downward pressing pressure. When placing the blood bag, the medical staff can place the blood bag braid and the donor tube in the U-shaped frame 93 and the sliding frame. Between the moving frames 91, just before the turntable 31 is about to rotate again, the translation drive 58 drives the movable rod 12 to retract, the movable rod 12 drives the push plate 99 to reset and retract, the elastic element 98 is released from the force and drives the longitudinal rod 92 to reset and translate, the two longitudinal rods 92 move closer to each other to concentrate and gather the blood bag braid and donor tube of the blood bag, and at the same time, when the longitudinal rods 92 move closer to each other, they cooperate with the fixing nail 96 to drive the protrusion 97 to rotate eccentrically until the longitudinal rod 92 moves to the near limit distance, the protrusion 97 rotates eccentrically and abuts the U-shaped frame 93 to move down, the U-shaped frame 93 moves down and can cooperate with the sliding frame 91 to press down and fix the blood bag braid and donor tube of the blood bag in the gathering, and repeat in this way;
[0090] After the blood bags are placed, medical staff can close the first rotary drive component 51 and start the second rotary drive component 54. At the same time, the gate assembly 8 is activated to open the irradiation port. The second rotary drive component 54, in conjunction with the second drive shaft, drives the rotating plate 55 to rotate. The rotation of the rotating plate 55, in conjunction with the connecting rod 56, drives the power rod 57 and the L-shaped folding rod 10 to rotate back and forth. The L-shaped folding rod 10 rotates back and forth around its long axis and drives the second bevel gear 14 and the turntable 31 to rotate back and forth. At the same time, the second bevel gear 14 rotates and meshes with the first bevel gear 13, so that the turntable 31 and the second bevel gear 14 rotate back and forth around the axis of the turntable 31, so as to fully shake the blood bags on the blood bag fixing assembly 32, and continuously adjust the degree of shaking of the blood bags on each blood bag fixing assembly 32.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
