Description

Technical Field

[0001] This invention relates to the field of blood radiation treatment technology, and more specifically, to a blood irradiator. Background Technology

[0002] Blood irradiation is an important medical technology, primarily used to inactivate pathogens such as viruses, bacteria, and parasites in blood products to ensure the safety of blood transfusions. Blood irradiation typically uses radioactive isotopes (such as cobalt-60 or cesium-137) or X-ray tubes as radiation sources to kill or inactivate pathogens in blood products through high-energy radiation.

[0003] The basic principle of blood irradiation is to use high-energy radiation to destroy the DNA or RNA of pathogens, thereby rendering them unable to reproduce or causing them to die. Blood irradiation is usually carried out in specialized irradiation equipment, which is designed with shielding devices to prevent radiation leakage and protect the safety of operators.

[0004] Currently, the placement of blood bags during blood irradiation significantly impacts the uniformity of radiation dose. Horizontally placed blood bags may result in uneven radiation dose distribution in the blood. Since the radiation source is typically located in the center or on one side of the irradiation chamber, horizontally placed blood bags may receive radiation doses from different directions, leading to excessively high or low radiation doses in certain areas. This uneven radiation dose distribution may affect the inactivation effect of blood products, causing some pathogens to fail to be effectively inactivated. Secondly, if the blood bag is not rotated during irradiation, certain areas may receive excessively high radiation doses, resulting in localized over-irradiation of the blood products. Excessively high radiation doses may adversely affect the quality and safety of blood products, such as damaging blood cell or protein structures. Summary of the Invention

[0005] To overcome the above deficiencies, the present invention provides a solution that overcomes or at least partially solves the above technical problems.

[0006] This invention provides a blood irradiation device, including an irradiation processing mechanism. The irradiation processing mechanism comprises a body, an irradiation chamber, a door panel, a partition, a linkage bearing, a linkage shaft, and an anti-detachment block. The body has an irradiation chamber for irradiating blood bags inside. The front of the irradiation chamber is covered by a door panel that is hinged to the door via a door hinge. A partition is also fixedly installed on the inner wall of the irradiation chamber. The interior of the body, the door panel, and the partition are all filled with a lead material layer for isolation. Several linkage bearings are fixedly fixed along a ring on the surface of the partition. A linkage shaft is interference-fitted and fixed through the inner ring wall of the linkage bearing. An anti-detachment block is installed at the lower end of the linkage shaft.

[0007] The lower end of the linkage shaft is provided with a blood bag vertical positioning mechanism. The blood bag vertical positioning mechanism includes a sleeve, a connecting rod, a connecting plate, a side frame, a threaded sleeve, and a threaded knob. The sleeve is rotatably fitted onto the surface of the linkage shaft. The lower end of the sleeve is slidably fitted with the anti-dislodgement block. Connecting rods are symmetrically assembled on both sides of the outer ring wall of the sleeve. The lower ends of the two connecting rods distributed along both sides are fixedly installed with connecting plates. A side frame is assembled on one side of the outer wall of the linkage shaft.

[0008] Preferably, the connecting rod and the side frame are both L-shaped, and a threaded sleeve is fixedly installed through the vertical position of the side frame. A threaded knob is installed inside the threaded sleeve, and one end of the threaded knob is pressed against the outer wall surface of the rod sleeve.

[0009] Preferably, a motor is provided above the partition, the outer ring wall of the motor is fixedly installed at the top of the irradiation cavity by a bracket, and the motor is provided with a drive shaft inside.

[0010] Preferably, the motor shaft end is fixedly connected to a drive shaft via a coupling, a drive gear is fixedly sleeved on the surface of the drive shaft, and a linkage gear is fixedly sleeved on the surface of any one of the linkage shafts, with the drive gear meshing with several linkage gears.

[0011] Preferably, a carrier is fixedly installed on one side of the lower end of the connecting plate. The carrier has an L-shaped structure, and the lower end of the carrier is provided with a platform for vertically placing and receiving blood bags. A perforated hole for irradiation is opened in the middle of the carrier.

[0012] Preferably, a positioning plate is fixedly installed on the lower end of the connecting plate away from the shelf, and a threaded sleeve is fixedly installed through the middle of the positioning plate, with a threaded knob installed inside the threaded sleeve.

[0013] Preferably, a transition bearing is provided at the end of the threaded knob two near the shelf, and the inner ring wall of the transition bearing is connected to the threaded knob two by an interference fit. A clamping plate is installed on the side of the transition bearing away from the threaded knob two.

[0014] Preferably, limit rods are fixedly installed at both ends of the clamping plate, and a limit sleeve corresponding to the position of the limit rod is fixedly installed through the inside of the positioning plate, and the surface of the limit rod is slidably sleeved with the inside of the limit sleeve.

[0015] Preferably, an irradiation source lifting mechanism is provided at the lower end of the irradiation cavity. The irradiation source lifting mechanism includes a lifting groove and a cylinder. The lower end of the irradiation cavity has a lifting groove, and a cylinder is fixedly installed at the lower end of the lifting groove. A piston rod for extension and retraction is provided inside the cylinder.

[0016] Preferably, the irradiation source lifting mechanism further includes a mounting plate and an X-ray tube. The piston rod end of the cylinder is fitted with a mounting plate, and an X-ray tube for blood irradiation is fixedly installed on the upper end of the mounting plate.

[0017] The targeted solution provided by this invention has the following beneficial effects:

[0018] 1. This solution achieves safe, uniform and efficient irradiation treatment of blood bags through overall structural design. Its body shell, door panel and internal partition are all filled with lead material layer, which can form a comprehensive radiation shield during irradiation, effectively prevent radiation leakage and ensure the safety of operators and the surrounding environment. After the door panel is tightly closed with the body, the irradiation chamber is in a completely closed state, further ensuring the reliability of physical isolation and radiation protection for irradiation operations.

[0019] 2. As described in 1, each blood bag has an independent linkage shaft, which is driven by a motor and rotates synchronously through a gear set. This allows the blood bag to rotate at a uniform speed in a vertically positioned state. This design enables the X-rays emitted from the center of the X-ray tube to irradiate all surfaces of the blood bag evenly, significantly improving the consistency of irradiation and the treatment effect, and avoiding irradiation blind spots or uneven doses that may occur due to a fixed irradiation angle.

[0020] 3. As described in 2, the blood bag is placed vertically on the carrier and clamped at the top by an adjustable clamping mechanism to ensure that it will not shift during rotation. At the same time, the X-ray tube can be raised and lowered to the optimal irradiation position by the cylinder, which not only improves the irradiation efficiency but also avoids long-term radiation damage to key components such as the motor and extends the service life of the equipment.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example

[0034] Reference Figures 1-7This invention provides a technical solution: a blood irradiation device, including an irradiation processing mechanism 1. The irradiation processing mechanism 1 includes a body 10, an irradiation chamber 11, a door panel 12, a partition 13, a linkage bearing 14, a linkage shaft 15, and an anti-detachment block 16. The body 10 has an irradiation chamber 11 inside for irradiating blood bags. The front of the irradiation chamber 11 is covered by a door panel 12 that is hinged to the door via a door hinge. A partition 13 is also fixedly installed on the inner wall of the irradiation chamber 11. The shell of the body 10, the door panel 12, and the partition 13 are all filled with a lead material layer for isolation. Several linkage bearings 14 are fixedly fixed along a ring on the surface of the partition 13. The inner ring wall of the linkage bearings 14 is interference-fitted and... A linkage shaft 15 is fixed through the body, and an anti-detachment block 16 is installed at the lower end of the linkage shaft 15. The shell and door panel 12 of the machine body 10 can completely shield the inside of the irradiation chamber 11 during blood pressure irradiation to ensure the safety of the irradiation process. Each blood bag is equipped with an independent linkage shaft 15 after vertical positioning. The linkage shaft 15 can rotate based on the linkage bearing 14, which can realize the self-rotation adjustment of the blood bag after vertical clamping and positioning. Thus, when the X-ray tube 33 in the center position is irradiated, it can ensure that the irradiation of each position of the blood bag is uniform. The partition 13 can shield and protect the motor 101 during use to avoid long-term irradiation and reduce the service life of the motor 101.

[0035] A blood bag vertical positioning mechanism 2 is provided at the lower end of the linkage shaft 15. The blood bag vertical positioning mechanism 2 includes a sleeve 20, a connecting rod 21, a connecting plate 22, a side frame 23, a threaded sleeve 24, and a threaded knob 25. The sleeve 20 is rotatably sleeved on the surface of the linkage shaft 15. The lower end of the sleeve 20 is slidably fitted with the anti-detachment block 16. Connecting rods 21 are symmetrically mounted on both sides of the outer ring wall of the sleeve 20. The lower ends of the two connecting rods 21 distributed along both sides are fixedly installed with connecting plates 22. A side frame 23 is mounted on one side of the outer wall of the linkage shaft 15. The sleeve 20 can be based on... The linkage shaft 15 rotates, allowing for easy manual adjustment of the rotation position of the carrier 201 when positioning the blood bag and the carrier 201 at the initial stage of irradiation. The connecting rod 21 ensures the stable installation of the connecting plate 22 and the rod sleeve 20. After rotational adjustment, the threaded knob 25 can be used to move the threaded sleeve 24 relative to the threaded knob 24. The threaded knob 25 can be used to tighten the rod sleeve 20. Thus, when the linkage shaft 15 rotates to adjust the blood bag later, it can prevent the connecting plate 22 from rotating arbitrarily, which would affect the normal self-rotation adjustment of the blood bag.

[0036] The connecting rod 21 and the side frame 23 are both L-shaped. A threaded sleeve 24 is fixed through the vertical position of the side frame 23. A threaded knob 25 is installed inside the threaded sleeve 24. One end of the threaded knob 25 is pressed against the outer wall of the rod sleeve 20. Since the threaded knob 25 is a manual structure, it can be adjusted by hand by turning it and the threaded sleeve 24.

[0037] Among them, a motor 101 is installed above the partition 13. The outer ring wall of the motor 101 is fixedly installed at the top of the irradiation chamber 11 by a bracket. The motor 101 has a rotating shaft for driving. After the power is turned on, the motor 101 can make the rotating shaft rotate. The motor 101 is a servo motor and is equipped with a servo controller. The speed and other parameters of the motor 101 can be set by a remotely connected processor, so that the rotation of the blood bag during irradiation is more adapted.

[0038] The motor 101 has a drive shaft 102 fixedly connected to its shaft end via a coupling. A drive gear 103 is fixedly sleeved on the surface of the drive shaft 102. A linkage gear 104 is fixedly sleeved on the surface of any linkage shaft 15. The drive gear 103 meshes with several linkage gears 104. When the motor 101 rotates, it can drive the drive shaft 102 to rotate and cause the drive gear 103 to rotate. Simultaneously, the drive gear 103 can mesh with multiple linkage gears 104, thereby enabling the linkage gear 104 to drive the corresponding linkage shaft 15 to rotate, thus achieving stable rotation of the blood bag.

[0039] The connecting plate 22 has a fixedly installed carrier 201 on one side of its lower end. The carrier 201 has an L-shaped structure and a platform at the lower end for vertically placing blood bags. The carrier 201 has a perforated hole 202 in the middle for irradiation to pass through. When the blood bags are placed vertically, they can be supported by the platform at the lower end of the carrier 201. The perforated hole 202 ensures that both the front and back sides of the blood bags can be irradiated during irradiation.

[0040] Among them, a positioning plate 203 is fixedly installed on the lower end of the connecting plate 22 away from the side of the shelf 201. A threaded sleeve 204 is fixedly installed through the middle of the positioning plate 203. A threaded knob 205 is installed on the internal thread of the threaded sleeve 204. The threaded knob 205 can be moved based on the threaded sleeve 204. The positioning plate 203 can ensure the stability of the position of the threaded sleeve 204.

[0041] Among them, the threaded knob 205 is provided with a transition bearing 209 at the end near the carrier 201. The inner ring wall of the transition bearing 209 is connected to the threaded knob 205 by an interference fit. A clamping plate 208 is installed on the side of the transition bearing 209 away from the threaded knob 205. When the threaded knob 205 rotates, it can rotate stably based on the transition bearing 209 and push the clamping plate 208 to move and adjust. Thus, the clamping plate 208 can cooperate with the carrier 201 to clamp and position the upper end of the blood bag when it is placed vertically. The transition bearing 209 can ensure the rotational stability of the threaded knob 205 when the clamping plate 208 moves.

[0042] Both ends of the clamping plate 208 are fixedly installed with limit rods 207. The positioning plate 203 has a limit sleeve 206 corresponding to the position of the limit rod 207 through it. The surface of the limit rod 207 is slidably sleeved with the inside of the limit sleeve 206. By sliding the limit rod 207 inside the limit sleeve 206, the horizontal movement of the clamping plate 208 can be stabilized.

[0043] The irradiation cavity 11 has an irradiation source lifting mechanism 3 at its lower interior end. The irradiation source lifting mechanism 3 includes a lifting groove 30 and a cylinder 31. The irradiation cavity 11 has a lifting groove 30 at its lower interior end. The cylinder 31 is fixedly installed at its lower interior end. The cylinder 31 has a piston rod for extension and retraction. When irradiation is required, the piston rod of the cylinder 31 can be extended so that the X-ray tube 33 can be extended from the lifting groove 30 and moved to the center position of the vertically placed blood bags for simultaneous irradiation of multiple blood bags.

[0044] The irradiation source lifting mechanism 3 also includes a mounting plate 32 and an X-ray tube 33. The piston rod end of the cylinder 31 is fitted with the mounting plate 32, and the upper end of the mounting plate 32 is fixedly fitted with an X-ray tube 33 for blood irradiation. The irradiation distance of the X-ray tube 33 is: the core components of the X-ray tube 33 are the cathode and the anode. The cathode is usually made of tungsten wire. When current passes through the tungsten wire, the tungsten wire is heated to a high temperature, thereby emitting electrons. The emitted electrons are accelerated under the action of the high voltage electric field between the cathode and the anode. The anode is usually made of a high melting point metal, such as tungsten, molybdenum or copper. When the high-speed electrons collide with the anode target, two main interactions occur. When the high-speed electrons approach the atomic nucleus of the target, due to the Coulomb force of the atomic nucleus, the direction and speed of the electrons will change. The target material undergoes a change, losing some kinetic energy, which is released as X-rays, producing a continuous spectrum of X-rays. When high-speed electrons collide with target atoms, they may knock inner-shell electrons out of their atomic orbitals, creating electron vacancies. Outer-shell electrons will then jump to the inner shell to fill the vacancies, releasing X-rays with specific energies, called characteristic X-rays. The energy of characteristic X-rays is related to the elemental type of the target material, and each element has specific characteristic X-ray spectral lines. Through these two interactions, X-ray tube 33 produces X-rays. Continuous spectrum X-rays have a wider energy range, while characteristic X-rays have specific energies. The X-rays produced by X-ray tube 33 can be controlled and adjusted using devices such as collimators and filters. The aforementioned X-ray irradiation is a conventional technique.

[0045] Operating Method: The irradiation processing mechanism 1 of the blood irradiator in this solution achieves comprehensive radiation shielding through the lead material layer filling the body 10, door panel 12, and partition 13. The irradiation cavity 11 serves as the core processing space. The door panel 12 on its front, when closed by hinges, ensures safe isolation during the irradiation process. The partition 13 is fixed to the inner wall of the irradiation cavity 11, separating the upper and lower spaces and protecting the upper motor 101 from radiation. The linkage shaft 15 is mounted via a linkage bearing 14 on the partition 13, allowing for... The inner ring of the bearing rotates, and the anti-detachment block 16 prevents the shaft from falling off. Each linkage shaft 15 corresponds to a blood bag positioning unit. The uniformity of irradiation is ensured by self-rotation adjustment. The motor 101 is fixed to the top of the irradiation chamber 11 by a bracket. Its rotating shaft is connected to the drive shaft 102 by a coupling. The drive gear 103 on the drive shaft 102 meshes with the linkage gear 104 on the linkage shaft 15, so that when the motor 101 starts, it drives all the linkage shafts 15 to rotate synchronously, so as to achieve uniform irradiation of the blood bag.

[0046] The blood bag vertical positioning mechanism 2 is sleeved onto the surface of the linkage shaft 15 via a sleeve 20, allowing for manual adjustment of the initial angle. The sleeve 20 is connected to the connecting plate 22 via connecting rods 21 on both sides to ensure stability. The side frame 23 is fixed to one side of the linkage shaft 15, and its threaded sleeve 24 and threaded knob 25 are used to fasten the sleeve 20. When the threaded knob 25 is manually tightened, its end presses against the outer wall of the sleeve 20 to prevent the connecting plate 22 from rotating accidentally during irradiation. The carrier 201 at the lower end of the connecting plate 22 has an L-shaped structure. A blood bag support platform is provided, with a central perforation 202 to ensure that irradiated light penetrates both sides of the blood bag. A positioning plate 203 is fixed to the other side of the connecting plate 22. The screw movement of the threaded sleeve 204 and the threaded knob 205 pushes the clamping plate 208 to move. The limiting rods 207 at both ends of the clamping plate 208 cooperate with the limiting sleeve 206 to ensure stable horizontal movement. The transition bearing 209 ensures that the clamping plate 208 is smoothly pushed forward when the threaded knob 205 is rotated, thereby working with the carrier 201 to clamp the upper end of the blood bag and achieve vertical fixation.

[0047] The irradiation source lifting mechanism 3 is located at the bottom of the irradiation chamber 11. The lifting and lowering of the X-ray tube 33 is controlled by the cylinder 31 in the lifting groove 30. When the piston rod of the cylinder 31 extends, it pushes the mounting plate 32 to rise, so that the X-ray tube 33 extends from the lifting groove 30 to the center of the blood bag placement area. The X-ray tube 33 serves as the irradiation source and synchronously irradiates the blood bags that are vertically positioned around it after it is raised. After the blood bags are fixed by the carrier 201 and the clamp 208, they rotate with the linkage rod 15. Combined with the center irradiation of the X-ray tube 33, it is ensured that all surfaces of the blood bags receive a uniform dose. After the irradiation is completed, the piston rod of the cylinder 31 retracts, driving the X-ray tube 33 back into the lifting groove 30 for safe storage. Throughout the process, the partition 13 shields the X-rays from affecting the motor 101, while the lead layer of the body 10 and the door panel 12 completely prevents radiation leakage.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
