Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to a radiation-proof lead door. Background Art
[0002] At present, according to the environmental evaluation of the lead doors in the operation rooms of relevant departments (radiotherapy department, CT room, nuclear medicine department, etc.) of hospitals and related institutions, it is found that the current lead doors and the ground cannot completely coincide without radiation leakage. One current solution is to add lead strips with a certain thickness on the ground outside the lead door. Although this method can pass the environmental evaluation, it is easy to trip patients and it is not suitable for wheelchairs and flat cars to pass through.
[0003] In the prior art, Chinese Patent CN220336784U discloses a radiation-proof self-shielding protection lead door, which includes a limit frame. The outer surface of the limit frame is fixedly connected with a drive box. The inner surface of the drive box is provided with a servo motor. The output end of the servo motor is fixedly connected with a drive shaft. The side of the drive shaft away from the servo motor is fixedly connected with a threaded rod. The threaded rod is rotatably connected in the inner cavity of the limit frame. The outer surface of the threaded rod is threadedly connected with a protection lead door body. The top of the limit frame is provided with a maintenance box. The outer surface of the maintenance box is hinged with a dust-proof door. This radiation-proof self-shielding protection lead door, through the cooperation of the limit frame, drive box, servo motor, drive shaft, threaded rod, protection lead door body, maintenance box, dust-proof door, handle, electric push rod, pressing plate, sponge block and guiding pipe, achieves the effect of facilitating the uniform maintenance of the protection lead door body and extending the service life of the protection lead door body as much as possible. This technology cannot achieve complete coincidence with the ground, and there will still be radiation leakage.
[0004] Chinese Patent CN220285609U discloses a protection lead door for radiation protection, which includes moving tracks. There are two moving tracks. The middle parts of the opposite surfaces of the two moving tracks are respectively provided with moving grooves. The middle parts of the front groove walls and the middle parts of the rear groove walls of the two moving grooves are respectively provided with limit grooves. Two moving mechanisms are respectively slidably connected in the two moving grooves. The lower ends of the upper two moving mechanisms and the upper ends of the lower two moving mechanisms are jointly fixedly connected with a radiation-proof lead door. The upper part of the front end of the radiation-proof lead door is inserted and fixedly connected with an observation window. The left part of the front end of the radiation-proof lead door is fixedly connected with a door handle. The utility model discloses a protection lead door for radiation protection. By setting the moving mechanism, the lead door moves more smoothly, improving the stability of the lead door. By setting the radiation-proof lead door and the reinforcing plate, the radiation-proof effect of the lead door is strengthened, improving the overall structural strength of the lead door. This technology prevents radiation leakage, but it is not conducive to the passage of patients' wheelchairs and hospital beds, etc.
[0005] Chinese Patent CN216588362U discloses a highly secure radiation-proof door with a shielding function for the bottom gap of the door, which includes a transmission frame installed on the wall and a shielding door that is in transmission connection with the transmission frame. The bottom surface of the shielding door is fixedly connected with a plurality of gear teeth. A chute and a placement groove are provided on the ground corresponding to the shielding door. This new type of highly secure radiation-proof door with a shielding function for the bottom gap of the door is configured such that the gear teeth on the shielding door are meshed with the first gear, and the transmission device is meshed with the first gear and fixedly connected to the shielding baffle. When closing the shielding door, the gear teeth drive the first gear to rotate, causing the second gear in the transmission device to drive the third gear to rotate. The third gear makes the rack plate push the shielding baffle upward, sealing and protecting the gap under the shielding door, thereby preventing electromagnetic radiation from leaking out through the gap under the shielding door and avoiding the phenomenon of electromagnetic radiation leakage. When the shielding door is opened, the shielding baffle descends to facilitate people's passage. This technology solves the problems of radiation protection and passage, but the grooves are not conducive to cleaning and are prone to debris accumulation, leading to equipment damage.
[0006] Therefore, we propose a radiation-proof lead door, which achieves the technical effects of preventing ray leakage of the lead door, facilitating the passage of wheelchairs and hospital beds, and avoiding the problems of cleaning and equipment damage caused by grooves.
