Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, and particularly relates to a multifunctional bed applicable to boron neutron capture therapy. Background Technique
[0002] Boron neutron capture therapy (BNCT) is a radioactive therapy that uses neutrons to react with boron elements in tumors to produce highly lethal rays to destroy cancer cells. This treatment method has the following characteristics:
[0003] Targeted therapy: In BNCT, a boron-containing drug is injected into the patient. This drug has a strong affinity for cancer cells and can quickly accumulate in cancer cells, equivalent to "marking" the cancer cells, while having less distribution in other normal tissues;
[0004] High lethality: When neutrons are captured by boron in cancer cells, highly lethal alpha particles and lithium ions are produced. The ranges of these rays are very short, only the length of a single cancer cell, so they can accurately kill cancer cells without damaging surrounding tissues;
[0005] Short treatment cycle: The entire treatment process generally only requires one irradiation, and the total irradiation duration is within 0.5 hours, greatly reducing the treatment time and inconvenience;
[0006] Low side effects: Due to the high selectivity of boron drugs for tumor cells, the incidence and severity of adverse reactions after BNCT treatment are lower than those of conventional radiotherapy. Common side effects include mild skin radiation damage, oral mucositis, local hair loss, etc., but these symptoms are mild and can resolve on their own.
[0007] As an emerging cancer treatment method, BNCT has shown its unique advantages and treatment effects in some cases, especially in cases such as pediatric malignant brain tumors, recurrent occipital osteosarcoma, and thoracic mediastinal peripheral nerve sheath tumors, showing good treatment effects and low side effects.
[0008] When using radioactive boron neutrons to perform capture therapy on a patient's head, generally the patient needs to lie on a multifunctional bed for head treatment. Currently, when performing radioactive boron neutron capture therapy, it is often necessary to place radiation protection pads on the body parts that do not need treatment. The radiation protection pads are used to provide radiation protection for the parts of the patient that do not need treatment except the head. However, when using radiation protection pads to cover the parts that do not need treatment, they are prone to falling off, and when using radiation protection pads multiple times, medical staff are prone to forgetting and causing loss.

[0031] When performing boron neutron capture therapy on the patient's head, the person lies on the bed frame 9, and the patient's feet extend into the inner wall of the arc-shaped fixed cover 8. Then, the driving component drives the arc-shaped sliding cover 7 to slide towards the position of the patient's upper limb.

[0041] When it is necessary to adjust the height of the bed frame 9, start the adjustment motor 27. The adjustment motor 27 drives the screw rod 33 to rotate. When the screw rod 33 rotates, it will drive the rotating block 30 to slide along the fixed rod 31. The rotating block 30 is rotatably connected to the rotating frame 28. Furthermore, when the rotating block 30 moves left and right, the rotating frame 29 will rotate. When the rotating frame 29 rotates, the height of the bed frame 9 will change. When the rotating frame 29 rotates, the rotating plate 32 will rotate, enabling the rotating frame 29 to rotate stably.
[0042] Working principle: When performing boron neutron capture therapy on the patient's head, the person lies on the bed frame 9, and the patient's feet extend into the inner wall of the arc-shaped fixed cover 8. Then start the drive motor 15. The drive motor 15 drives the worm 18 to rotate. Since the worm gear 18 meshes with the worm 16, it drives the drive rod 17 to rotate. When the drive rod 17 rotates, it will drive two sets of active bevel gears 21 to rotate. Also, since the driven bevel gear 19 meshes with the active bevel gear 20, it drives two sets of drive screw rods 21 to rotate synchronously. When the drive screw rods 21 rotate, they will drive the moving block to slide with the arc-shaped sliding cover 7. Furthermore, through the drive assembly, the arc-shaped sliding cover 7 is driven to slide towards the patient's upper limb position. Anti-radiation coatings are applied on the outer surfaces of the arc-shaped fixed cover 8, the arc-shaped sliding cover 7, and the soft rubber isolation strip 34. The arc-shaped sliding cover 7 and the arc-shaped fixed cover 8 cooperate to form a protection chamber for the part below the patient's head, thereby achieving the purpose of anti-radiation isolation, avoiding the easy detachment of the anti-radiation pad when covering the parts that do not need treatment, and avoiding the loss of the anti-radiation pad due to the easy forgetting of medical staff.
[0043] The height adjustment component provided can adjust the height of the bed frame 9, effectively improving the functionality of this multifunctional bed body. When it is necessary to adjust the height of the bed frame 9, start the adjustment motor 27. The adjustment motor 27 drives the screw rod 33 to rotate. When the screw rod 33 rotates, it will drive the rotating block 30 to slide along the fixed rod 31. The rotating block 30 is rotatably connected to the rotating frame 28. Furthermore, when the rotating block 30 moves left and right, the rotating frame 29 will rotate. When the rotating frame 29 rotates, the height of the bed frame 9 will change. When the rotating frame 29 rotates, the rotating plate 32 will rotate, enabling the rotating frame 29 to rotate stably.
[0044] The provided infusion rod 6 facilitates the medical staff to perform infusion operations on the patient.
