AI Technical Summary
The existing radiology protective doors cannot completely shield the rays, resulting in patients who may be subjected to trace radiation when outside the door and lack alarm function. At the same time, when the radiation inside the door is too large, there is a risk of radiation damage, and metal objects on the patient cannot be detected.
A radiological protective door system with alarm function is designed, including a radiation alarm setting on the front side of the protective door leaf and a wraparound metal detection mechanism designing a back side of the door frame. Through the linkage between the radiation monitor and the acousto-light alarm, the radiation in the radiation chamber is monitored and alarmed, and the metal objects on the patient are detected before entering.
It effectively avoids the risk of radiation from patients outside the door, and reminds patients to stay away from the protective door through the alarm function; at the same time, the detection mechanism can ensure that there are no metal objects before the patient enters the radiation room, reducing the safety risks caused by metals in the radiation room.

Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of radiation protection doors, and particularly relates to a radiology protection door system with an alarm function. Background Art
[0002] Radiology protection doors are used in radiology equipment rooms. Radiology protection doors, also known as medical lead doors, are commonly used in places that require radiation protection such as radiology departments, laboratories, operating rooms, physical examination centers, CT rooms, DR rooms, and dental clinics. The weight of ordinary protection doors is about 50 kg - 100 kg; the weight of radiology protection doors is 200 kg - 500 kg. The filling material of the door body of ordinary protection doors is wood board and honeycomb paper; the filling material of the door body of radiology protection doors is wood board and lead plate, and lead plate is a metal with a high density. In addition, radiology protection doors can not only prevent theft but also prevent the penetration of rays, avoiding radiation damage to the body.
[0003] Although radiology protection doors have the ability to prevent the penetration of rays compared with ordinary protection doors, the protection doors currently used in radiology departments have the following defects: Since the protection doors cannot completely shield the rays, patients outside the protection doors will still receive a small amount of radiation within the safe range. If the radiation dose inside the radiology room behind the door is excessive or too intense, there will be a risk of radiation damage to the space behind the protection door, and the current protection doors do not have the ability to give a prompt alarm; Secondly, since patients need to remove the metal objects on their clothes before radiology examinations or treatments, and there may be small and unnoticed metal objects on the patients' clothes, combined with the fact that the current protection doors do not have the ability to detect the metal objects on the patients' bodies, those skilled in the art hereby propose a radiology protection door system with an alarm function. Summary of the Invention
[0004] The purpose of the present invention is to provide a radiology protection door system with an alarm function for solving the existing technical problems proposed in the above background art.
[0005] The technical solution adopted by the present invention to achieve the above purpose is as follows:
[0006] A radiology protection door system with an alarm function includes a protection door mechanism. Above the front surface of the protection door mechanism, a radiation alarm is provided, and a surrounding metal detection mechanism is provided on the rear end surface of the protection door mechanism;
[0007] The protection door mechanism includes a ground rail embedded and fixed inside the ground, an electric push-pull device fixed to the wall, and a protection door leaf that moves horizontally left and right between the ground rail and the electric push-pull device. And on the left rear side of the top surface of the ground rail, a door frame fixed to the front port of the door opening is provided;
[0008] The surrounding metal detection mechanism includes an arched tunnel fixed to the rear end port of the door frame, a driving motor fixedly connected to the upper surface of the arched tunnel, and a rotating ring rotatably arranged in the top area of the inner cavity of the arched tunnel. A vertical plate is fixedly connected to the bottom surface of the rotating ring, and several groups of metal detectors are fixedly connected to the inner surface of the vertical plate. Specifically, before the patient enters the radiotherapy room through the protective door leaf and the door frame, the patient stands at the middle position of the inner cavity of the arched tunnel, and the driving motor drives the transmission shaft to rotate to drive the rotating ring to slowly rotate several circles, so that several groups of metal detectors on the inner side of the vertical plate surround the patient several times, thereby detecting whether there are metal objects on the patient's clothes or in the body.
[0009] The radiation alarm includes a bottom case fixed to the upper part of the front side surface of the protective door leaf, an end cover fixed to the front end face of the bottom case, and a sound and light alarm fixedly connected to the inner cavity of the bottom case. A battery for powering the sound and light alarm is arranged inside the bottom case. Specifically, after the pulling end of the electric push-pull device pulls the protective door leaf to move horizontally left and right, the protective door leaf will block the front port of the door frame, and the rear end face of the protective door leaf will contact the sealing strip on the front end face of the door frame. During the horizontal movement of the protective door leaf left and right, the rollers at the bottom of the protective door leaf will move along the slide rail on the top of the ground rail. Since a layer of lead plate is filled inside the protective door leaf, the lead plate will block the radiation in the radiotherapy room from escaping to the outside. After the radiation dose monitor is tightly clamped in the groove by relying on the tension of the arc-shaped elastic piece, the detection end of the radiation dose monitor will face the inside of the radiotherapy room. When the radiation dose in the room is too high, the radiation dose monitor will transmit the detected data to the radiation alarm, and after the battery powers the sound and light alarm, the sound and light alarm will generate an alarm sound and a warning light to prompt the patient outside the door to stay away from the protective door.
[0010] In the technical solution of the above-mentioned radiology protection door system with an alarm function, preferably: a door handle is fixedly connected to the left side position of the front end face of the protective door leaf, and 4-6 groups of rollers embedded in the ground rail for sliding are fixedly connected to the bottom surface of the protective door leaf.

[0014] In the above technical solution of a radiology protection door system with an alarm function, preferably: several sealing strips are adhesively fixed to the front end face of the door frame through an adhesive, and a slide rail for the rollers at the bottom of the protection door leaf to roll is arranged on the upper surface of the ground rail.
[0015] In the above technical solution of a radiology protection door system with an alarm function, preferably: the front end face of the arched tunnel is fixedly connected to the rear end port of the door frame, and the top surface of the arched tunnel is fixedly connected to the outer surface of the driving motor.
[0016] In the above technical solution of a radiology protection door system with an alarm function, preferably: the output end of the driving motor is connected through a coupling to a transmission shaft passing through the arched tunnel, and the bottom end of the transmission shaft is connected to 4 connecting rods arranged in an annular array, and the inner ring surface of the rotating ring is fixedly connected to the outer ends of the connecting rods.
[0017] In the above technical solution of a radiology protection door system with an alarm function, preferably: a circular hole for the transmission shaft to pass through and rotate is opened in the middle area inside the arched tunnel, and a bearing is arranged inside the circular hole.
[0018] In the above technical solution of a radiology protection door system with an alarm function, preferably: the power supply wire and the signal transmission line of the metal detector are both connected to the control terminal through an electric slip ring, and there is a distance of 2 - 4 cm between the outer surface of the vertical plate and the inner cavity side wall of the arched tunnel.
[0019] As can be seen from the above technical solution, compared with the prior art, the present invention provides a radiology protection door system with an alarm function, and the present invention has the following beneficial effects:
[0020] In the technical solution of the present invention, a radiation alarm with a sound and light alarm function is arranged on the outer side of the protection door leaf, and a radiation monitor is clamped and arranged on the inner side of the protection door leaf. Relying on the mutual linkage of the two, after the radiation monitor monitors the radiation dose inside the radiology department, a sound and light alarm prompt is provided to the patients waiting outside the door through the radiation alarm, avoiding the patients outside the door from being affected by radiation; secondly, a tunnel leading to the inside of the radiology department is designed at the rear side of the door frame, and a surrounding metal detection mechanism is arranged in the tunnel, so that the patient can detect metal objects on the body before entering the radiation detection, avoiding the metal on the patient from being brought into the radiology department.
