Example one
Referring to fig. 1-3, an embodiment of the present invention provides an automatic tracking protective curtain apparatus, including a lead protective device 100 (which may be used for protection against X-rays, etc. by using a similar manufacturing process as a lead curtain), a light detection device 200, a driving mechanism 300, a controller 400, a distance measuring device 500, a radiation emitting device 600, and a radiation detecting device 700.
The radiation emitting device 600 and the radiation detecting device 700 are disposed opposite to each other, and are controlled to keep synchronous movement under normal conditions, so as to ensure that the emitted radiation can be detected properly, and normal operation is not affected. The distance measuring device 500 is disposed at the bottom of the radiation emitting device 600 or the radiation detecting device 700 and is electrically connected to the controller 400. The distance measuring device 500 detects the height of the ray emitting device 600 or the ray detecting device 700 from the ground, and the length from the edge of the ray emitting device 600 or the ray detecting device 700 to the center emitting part or the detecting part is added, so that the distance from the center emitting part or the detecting part to the ground can be obtained, and the controller can move the lead protection device 100 to a proper position in advance to enable the lead protection device to be on the same straight line with the centers of the ray emitting device 600 and the ray detecting device 700.
The lead shielding device 100 includes two shielding members 101, each mounted to a driving mechanism 300, and the shielding members are moved in translation by the driving mechanism 300. The light detection device 200 in this embodiment is mounted on one of the protection members 101, and determines the distance to be avoided by acquiring the irradiation range of the visible light generated by the detection ray emission device 600 on one side. The controller 400 may synchronously move the two protection members 101 to translate the same distance in different directions by the driving mechanism 300. Wherein, the visible light is generated according to the ray emission angle preset by the ray emission device 600.
The automatic tracking protective curtain device of the embodiment can synchronize the lead protective device 100 to the initial position of the ray emitting device 600 through the distance measuring device 500, and then judge the irradiation area of the protective part 101 on one side through the light detection device 200, so that the two protective parts 101 synchronously move to the same distance towards the two sides through the driving mechanism 300, and the detection efficiency of the radiology department can be improved.

The light sensor 201 detects the visible light and transmits a signal to the signal processing unit 202, and the signal is transmitted to the controller 400 through the transmitting unit 203, indicating that the lead protection device 100 needs to be translated away from the irradiation area. Until the light sensor 201 fails to detect visible light, it is considered that the appropriate position has been moved. Referring to fig. 5, the signal processing unit may be formed by an analog-to-digital converter AD and a processor MCU, which are connected in sequence.
The front end of the optical detection device 200 may be provided with an optical filter for filtering out visible light with a specific wavelength (for example, filtering light with a wavelength of over 700 nm), so that the optical detection device 200 only detects the visible light emitted by the image device, thereby avoiding the interference of ambient light to the detection.
Before the detection, this protection curtain equipment can be started through medical personnel's button, also can set up the position that the sensor detected image equipment in addition, if detect image equipment and remove then think that the inspection is about to begin, then start protection curtain equipment and carry out the action that resets.
The reset action is performed during the start-up phase, which may include moving the lead shielding device 100 to a position (e.g., a centerline position) opposite to the radiation emitting device (typically a bulb) via the driving mechanism 300, so as to facilitate subsequent positioning and also to protect other parts that do not need to be detected from being directly irradiated by the radiation.
When the medical staff is finished, the medical staff can be reminded in acousto-optic modes such as a prompt tone, a highlight of a screen (or an icon), flashing and the like so as to prompt that the lead protection equipment 100 is moved to a proper position. Correspondingly, the automatically tracking protective curtain device of the embodiment may include an acousto-optic warning unit for generating an acousto-optic warning after the visible light passes through the controller.
