Description

Technical Field

[0002] In the field of modern tumor treatment, patients hospitalized in hospitals often face special medical conditions and potential risks after taking anticancer drugs. Many anticancer drugs, especially some targeted drugs or chemotherapy drugs labeled with radionuclides, will make the patient himself a radiation source. For example, when some iodine-131 labeled drugs are used to treat thyroid cancer, the drugs will continue to emit radioactive rays in the body, causing radiation effects on the surrounding environment and personnel. During their hospitalization, these patients will inevitably need to undergo various examinations, treatments, and transfers between wards.

[0003] Currently in the traditional medical environment, there is a lack of effective protective equipment specifically for the transfer of patients with radiation source characteristics after taking anti-cancer drugs. Ordinary beds cannot prevent the spread of radiation during the transfer process, which exposes medical staff, other patients in the same ward and other people in the hospital to unnecessary radiation risks. In addition, due to long-term and frequent contact with radiation source patients, the accumulated radiation dose of medical staff may cause serious damage to their physical health, such as increasing the risk of cancer, blood system diseases and genetic diseases. For other patients in the same ward, radiation exposure may interfere with their own treatment process, affect their physical recovery, and even cause new health problems.

[0004] Therefore, it is necessary to propose a radiation-proof bed for patient transfer to effectively reduce the radiation hazard of radiation source patients to the surrounding environment and personnel during the transfer process, ensure the safety and orderly operation of the medical environment, and improve the radiation protection level of the entire medical process.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Embodiment 1: In the present invention, referring to Figure 1 - Fig.10 Shown: A radiation-proof bed for patient transfer, comprising: The rotating adjustment component 3 is symmetrically installed at the left and right ends of the sterile radiation-resistant protective cover 5, with a power source at one end and no power source at the other end, and is used to automatically unfold when a patient needs to be transferred, so that the sterile radiation-resistant protective cover 5 and the side radiation protection plate 4 can be connected after the patient is placed on the bed 9; The adjustment component 10 is installed at the left and right ends of the frame of the bed body 9, one end is movable, and the other end is fixed. Before the patient is transferred, the movable adjustment component 10 is rotated to make room for the patient. After the patient is transferred, the movable adjustment component 10 is adjusted back to form a docking with the side end of the sterile anti-radiation protective cover 5; The dynamic source monitoring and adjusting protection component 8 is installed on the inner wall surface of the sterile radiation-resistant protective cover 5, and after forming a lateral fixed-point displacement along the length side of the sterile radiation-resistant protective cover 5, it is dynamically located inside the sterile radiation-resistant protective cover 5 after covering to form an adjustment according to the monitoring data fed back by the radiation source detection sensor, so as to protect the radiation source at a fixed point; A bed frame structure 1 is used to form a mobile carrier when transferring a patient.

[0022] In a specific scheme: when transferring a patient with radiation source characteristics after taking anti-cancer drugs, the entire radiation-proof bed is in a sealed protective state, so that the rotating adjustment component 3 is in a retracted state, and the sterile radiation-proof protective cover 5 and the edge radiation protection plate 4 are closely connected to form a closed protective space to protect the internal bed body 9. When the patient transfer instruction is received and the transfer position is reached, the motor located at the power source end of the rotating adjustment component 3 is started, driving the rotating adjustment component 3 to gradually unfold, separate the sterile radiation-proof protective cover 5 and the edge radiation protection plate 4, and expose the space above the bed body 9. At the same time, one end of the movable setting in the adjustment component 10 on the bed body 9 begins to rotate and rotates outward at a suitable angle and speed to make enough space for the patient to enter. After the medical staff places the patient steadily on the bed body 9, the movable end of the adjustment component 10 begins to return to its position, rotates back to the position corresponding to the side end of the sterile radiation-proof protective cover 5 according to the preset path and speed, and performs precise docking. , through the positioning sensor and external logic controller on the adjustment component 10, the accuracy and tightness of the docking are ensured to prevent gaps from causing radiation leakage. When the patient is exposed to the external environment during the transfer process, the dynamic source monitoring and adjusting protection component 8 continuously monitors the radiation source. When a radiation source is detected, the optimal protection position is immediately calculated according to the position information of the radiation source, and the lateral fixed-point displacement mechanism is started to quickly move to the corresponding position along the length side of the sterile anti-radiation protection cover 5, and the protection action is carried out to isolate the radiation source from the patient. After the patient is successfully transferred to the bed 9 and the adjustment component 10 completes the docking, the rotation adjustment component 3 starts the reverse action, and the sterile anti-radiation protection cover 5 and the edge radiation plate 4 are closed again to restore to the initial closed protection state. At this time, the dynamic source monitoring and adjusting protection component 8 continues to dynamically adjust the protection according to the real-time position of the radiation source to ensure that the patient is always in the best protection state during the entire transfer process and subsequent movement.

[0023] Embodiment 2: In the present invention, according to Figure 3 , Figure 4 , Figure 7 , Fig. 9 and Fig.10 As shown, the dynamic source monitoring and regulating protection component 8 includes: The transverse linear rail 81, the connecting rod 80, the semi-arc rack frame 83 and the connecting sliding connection seat 84, the transverse linear rail 81 is set as a group, and the other side is a guide sliding frame, which is used to cooperate with the transverse linear rail 81 to drive the two groups of semi-arc rack frames 83 fastened to the bottom of the connecting rod 80. The connecting sliding connection seat 84 is located outside the top frame of the two groups of semi-arc rack frames 83 to form a sliding connection, and the top surface of the connecting sliding connection seat 84 does not contact the inner wall surface of the sterile anti-radiation protective cover 5.

[0024] A bidirectional energy-saving protection motor 890 is installed inside the connecting sliding connection seat 84, and the left and right output ends of the bidirectional energy-saving protection motor 890 are connected to a speed control shaft 893, and the side end of the speed control shaft 893 is connected to a transmission gear 892. The transmission gear 892 and the two sets of semi-arc rack racks 83 form a meshing connection, and cooperate with the power output of the bidirectional energy-saving protection motor 890 to enable the transmission gear 892 to be dynamically adjusted along the arc trajectory of the two sets of semi-arc rack racks 83.

[0025] The bottom wall surface of the bidirectional energy-saving protection motor 890 is fastened with a radiation blocking adsorption arc plate 891 through a connecting column. The radiation source detection sensor is installed on the outside of the connecting column to form a circular array distribution. The side wall surface of the sliding connecting seat 84 is fastened with a control frame 85. The side end of the control frame 85 is connected to an electric adjustment arm 86. The bottom end of the electric adjustment arm 86 is connected to a 3D sensor and a camera 87. The bottom of the control frame 85 is fastened with a rotating adjustment frame 88. The bottom of the rotating adjustment frame 88 is installed with an ultrasonic disinfection structure 89.

[0026] In a specific solution, when the patient is being transferred, the radiation source detection sensor, 3D sensor and camera 87 start working to collect and monitor the radiation source diffused around the patient. The radiation source detection sensor is distributed in a ring array to monitor the radiation situation in all directions in real time. Once the radiation source is detected, the radiation intensity, direction and other information are transmitted to the external logic controller. At the same time, the 3D sensor and camera 87, under the control of the electric adjustment arm 86, scan the spatial environment and objects in the protection area to obtain detailed three-dimensional spatial information and visual image information, such as the patient's position, shape, layout of surrounding equipment, etc., and transmit these data to the external central control machine. The external central control machine receives the radiation After receiving the data from the source detection sensor, 3D sensor and camera 87, the built-in algorithm is used to accurately locate the radiation source, and a control instruction is issued according to the patient's position, protection requirements and the current state of the protection component, so that the two-way energy-saving protection motor 890 is started, and the power is transmitted to the transmission gear 892 through the speed control shaft 893. The transmission gear 892 starts to rotate along the arc trajectory of the two sets of semi-arc racks 83, thereby driving the radiation blocking adsorption arc plate 891 to be dynamically adjusted, so that when the patient is transferred and exposed to external scattered radiation, it can be timely positioned and moved to the key path between the radiation source and the external environment, forming an effective radiation shielding and adsorption barrier, so that the radiation blocking adsorption arc plate 891 is positioned according to the instructions of the external central control machine. The position and posture are precisely adjusted, and moved to the outside of the area with strong radiation close to the patient's body, so as to limit the radiation to the smallest range as much as possible and prevent it from spreading to the surrounding medical staff, other patients and medical equipment. At the same time, according to the surrounding equipment layout information obtained by the 3D sensor and camera 87, the radiation blocking adsorption arc plate 891 will avoid some important medical pipelines, instrument operation areas, etc., to avoid interference with normal medical treatment during the protection process. Moreover, during the movement, the speed of the transmission gear 892 is accurately controlled by the speed control shaft 893 to ensure that the radiation blocking adsorption arc plate 891 can reach the target position smoothly and quickly, and can stably maintain the appropriate position and angle after arriving, so as to continuously and effectively block Radiation, to ensure radiation safety during the patient transfer process, reduce the potential harm of radiation to the surrounding environment and personnel. After the transfer, the ultrasonic disinfection structure 89 at the bottom of the rotating adjustment frame 88 can be started according to the preset control command, so that the ultrasonic disinfection structure 89 emits ultrasonic disinfection mist to disinfect the internal space and surrounding areas formed by the sterile anti-radiation protective cover 5, remove possible contaminants such as bacteria and viruses, ensure overall hygiene and safety, and prepare for subsequent use. During the entire protection process, the radiation source detection sensor, 3D sensor and camera 87 continuously monitor the environment and continuously transmit new data to the external central control machine and external logic controller, so that when the position and intensity of the radiation source scattered by the patient changes,The external central control machine and the external logic controller will adjust the protection strategy in time, and drive the two-way energy-saving protection motor 890 and the electric adjustment arm 86 and other components again to dynamically adjust the position and posture of the radiation blocking adsorption arc plate 891 to ensure that the best protection effect is always maintained, so that the overall real-time monitoring and precise protection of dynamic radiation sources can be achieved, and the protection strategy can be adjusted in time according to the changes in the radiation source to ensure that the radiation emitted by the patient during the transfer process can be absorbed and blocked, reducing the exposure of medical staff, other patients in the same ward or other people in the hospital to the radiation risk emitted by the patient, ensuring medical safety and personnel health, effectively blocking the spread of radiation, and accurately positioning and dynamically adjusting to minimize interference with medical operations.

[0027] Embodiment 3: In the present invention, according to Figure 1 - Figure 5 As shown, the rotation adjustment component 3 includes: The side guard 31, the left frame 32, the right frame 33 and the rotation control drive connector 34, the right frame 33 is installed on the left frame surface of the bed body 1, the side end of the rotation control drive connector 34 is connected to the driving control motor, the middle end of the left frame 32 and the right frame 33 is installed with a rotating ring, the bottom end surface of the rotating ring is slidably connected with a connecting groove frame 36, the interior of the connecting groove frame 36 is installed with a friction wheel 37, and the friction wheel 37 and the inner ring diameter surface of the rotating ring form a contact setting.

[0028] The bottom end of the connecting groove frame 36 is fastened with a connecting adjustment column. The driving and regulating motor drives the connecting groove frame 36 and the friction wheel 37 to slide and connect along the bottom end surface of the rotating ring by rotating the regulating driving connector 34 in cooperation with the connecting adjustment column. The side wall surface of the connecting groove frame 36 is fastened with a connecting connecting fixture 38, and the side end of the right frame 33 is fastened with the inner ring rail groove arc frame 35.

[0029] The inner wall surface of the side end of the sterile radiation-resistant protective cover 5 is fastened with a connector 11, the connecting piece 38 and the connector 11 are fastened together, and the two ends of the side of the sterile radiation-resistant protective cover 5 are located inside the grooves on the side surface of the inner ring rail groove arc frame 35 to form a sliding connection.

[0030] In a specific solution, when the patient needs to be transferred, after receiving the start signal, the driving and regulating motor starts to work, and the power of the driving and regulating motor is transmitted to the connecting and adjusting column through the rotating and regulating driving connector 34, thereby driving the connecting slot frame 36 to start moving. Since the friction wheel 37 is in contact with the inner diameter surface of the rotating ring, when the connecting slot frame 36 moves, the friction wheel 37 will roll along the bottom end surface of the rotating ring, thereby driving the rotating ring to rotate. As the rotating ring rotates, the sterile anti-radiation protective cover 5 closely connected to the rotating ring also starts to move, and the sterile anti-radiation protective cover 5 also starts to move. The two ends of the side of the radiation protection cover 5 slide along the slots of the inner ring rail groove arc frame 35. Under the connection of the connecting fastener 38 and the connecting member 11, the sterile radiation protection cover 5 is smoothly rotated at an angle, so that the sterile radiation protection cover 5 and the edge radiation protection plate 4 are separated, gradually exposing the bed 9. Then, the lateral displacement guide rail at the bottom of the bed 9 drives the bed 9 with the cooperation of the automatic locking bracket. After the electric extension displacement is moved to the transferred equipment, the automatic locking bracket is opened and separated from the bed 9, so that the bed 9 The device is transferred to the target in an electric, stable and precise extension displacement, and then returns to its original position under the action of the lateral displacement guide rail, which effectively reduces the bumps, shaking and improper touching of the patient's body that may occur during manual transportation, and ensures the radiation protection safety of the patient during the transfer process, and improves the efficiency and stability of the transfer process, reduces the operating difficulty and labor intensity of medical staff, and minimizes the adverse effects of the transfer operation on the patient's condition and the radiation hazards to the surrounding environment and personnel. In this process, the drive and control motor accurately controls the movement of the rotation and control drive connector 34 according to the preset control feedback information (such as rotation angle, speed, etc.), ensuring the extension and rotation of the sterile anti-radiation protective cover 5. The opening and closing actions are smooth and orderly, without any jamming or shaking, thus avoiding any impact on surrounding equipment or personnel. Later, when the patient needs to be transferred to the bed 9 again, the lateral displacement guide rail drives the automatic locking bracket to the bottom of the bed 9 again, and the automatic locking bracket and the bed 9 form a self-locking structure, driving the bed 9 back to the inner space of the sterile anti-radiation protective cover 5. Then the driving and regulating motor is reversed, and the connecting groove frame 36 drives the friction wheel 37 to roll in the opposite direction along the rotating ring in the opposite order of actions, pulling the sterile anti-radiation protective cover 5 back to its original position and precisely docking it with the border radiation protection plate 4. During the return process, the position and state of the sterile anti-radiation protective cover 5 are also monitored in real time by sensors to ensure that it is accurately restored to its initial closed state to ensure radiation protection performance.

[0031] Embodiment 4: In the present invention, according to Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown, the adjustment component 10 includes: The side fixed rotating frame 101, the first arm frame 102 and the second arm frame 103, the side fixed rotating frame 101 is fastened to the side end frame surface of the bed body 1, the side ends of the left first arm frame 102 and the second arm frame 103 are fastened to the side radiation protection plate 4, and are located at the side end of the side fixed rotating frame 101 to form a rotation connection, the side ends of the right first arm frame 102 and the second arm frame 103 are inserted and connected to the right side cover edge of the sterile anti-radiation protective cover 5, and the side wall surface of the sterile anti-radiation protective cover 5 is slidably connected with a movable adjustable radiation protection plate 6.

[0032] Electric control wheels 2 are arranged at the four ends of the bottom of the bed frame structure 1, and a synchronous hydraulic rod 7 is fastened to the bed side end of the bottom frame of the bed frame structure 1. A pneumatic pushing guide rod 12 is installed at the other side end of the bottom frame of the bed frame structure 1, and a scissor-type lifting frame 13 is installed at the side end of the pneumatic pushing guide rod 12. The pneumatic pushing guide rod 12 forms a synchronous operation with the synchronous hydraulic rod 7 under the cooperation of an external logic controller.

[0033] After the sterile anti-radiation protective cover 5 rotates and passes through the first arm 102 and the second arm 103 on the right side, the movable adjustable radiation protection plate 6 contacts the side end of the synchronous hydraulic rod 7, and the movable adjustable radiation protection plate 6 is forced to be accommodated and adjusted inside the side end of the sterile anti-radiation protective cover 5.

[0034] In a specific scheme, after receiving the patient transfer instruction, the bed frame structure 1 starts to prepare for the patient to enter. First, the pneumatic push guide rod 12 starts to work under the signal drive of the external logic controller, pushing the scissor lift 13 to extend, and adjusting the height of the bed frame structure 1 to a suitable position, so as to facilitate the transfer of the patient to the bed frame structure 1 under the cooperation of the above-mentioned lateral displacement guide rail and the automatic locking bracket, and the synchronous hydraulic rod 7 performs synchronous hydraulic lifting according to the unfolding and lifting height of the scissor lift 13. At the same time, the side end of the sterile anti-radiation protective cover 5 where the first arm 102 and the second arm 103 on the right side are located begins to rotate. This rotation process is realized by the external logic controller controlling the corresponding rotation adjustment component 3. As the sterile anti-radiation protective cover 5 rotates, the movable adjustable radiation protection plate 6 begins to move relative to the synchronous hydraulic rod 7. When the sterile anti-radiation protective cover 5 rotates to a certain angle, the movable adjustable radiation protection plate 6 contacts the side end of the synchronous hydraulic rod 7. Due to the continued rotation of the sterile anti-radiation protective cover 5, the movable adjustable radiation protection plate 6 is affected by the synchronous hydraulic rod 7. The force is applied to the side end of the sterile radiation protection cover 5 for storage and adjustment. In this process, the protection performance of the entire radiation protection bed or the synchronous rate of lifting and lowering is avoided to be affected by the storage speed being too fast or too slow. At the same time, the first arm 102 and the second arm 103 on the left side are also driven by the corresponding control motor to drive the edge radiation plate 4 to perform appropriate rotation displacement to make enough space for the patient to enter. When the patient and the bed body 9 are transferred to the bed frame structure 1, the edge radiation plate 4 on the left side is also between the first arm 102 and the second arm 103. 3, so that the sterile anti-radiation protective cover 5 starts to rotate in the opposite direction and returns to its original position. During the rotation and return process of the sterile anti-radiation protective cover 5, the movable adjustable radiation shield 6 is separated from the force contact with the synchronous hydraulic rod 7, and gradually extends from the storage position to the initial state, and the sterile anti-radiation protective cover 5 is connected with the side wall surface of the edge radiation shield 4 to ensure that the protective performance of the radiation bed is fully restored. Then the electric control wheel 2 of the bed frame structure 1 transfers the patient to the designated location according to the preset route according to the instruction of the external logic controller.
