Abstract
The utility model discloses a safety device for a computed tomography (CT) scanning room, and aims to provide a device for preventing persons besides a scanned person from radiation damage in the scanning room. The safety device for the CT scanning room comprises a door, a CT machine exposure switch and a buzzer, wherein the door is provided with a circuit switch; and the circuit switch is connected in series with the buzzer through a lead and then connected in parallel with the CT machine exposure switch and the buzzer. The safety device can ensure that a doctor can switch on the exposure switch only when other persons besides the scanned person are not in an examination room and a door of the examination room is closed completely.
Description
Technical field
This utility model relates to a kind of safety device, and more particularly, it is a kind of radioprotective safety device that is used for CT Scan Room.
Background technology
At present, not relating to staff's inlet/outlet in the CT Scan Room of various big hospital is connected with the exposure switch of CT machine, cause easily except that the other staff the person of being scanned also in inspection chamber or the inlet/outlet of inspection chamber when not closing, the doctor just presses the exposure switch, makes it to resting in the inspection chamber except that the personnel the person of being scanned and the personnel outdoors cause radiating harm.
The utility model content
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of safety device that can prevent to avoid except that the personnel the person of being scanned radiation hazradial bundle is provided.
In order to solve the technical problem of above-mentioned existence, this utility model adopts following technical proposals: a kind of CT Scan Room safety device, comprise the door of turnover inspection chamber and the exposure switch of CT machine, door is provided with contactor, and described contactor and exposure switch are connected mutually.
Owing to adopt the technique effect that technique scheme reached to be: because the door of CT Scan Room is provided with and the placed in-line contactor of CT machine exposure switch, the door that is inspection chamber must Close All Shi doctor could start the exposure switch, avoided the staff in CT Scan Room or do not shut the exposure switch that CT Scan Room door Shi doctor just presses the CT machine, prevented the staff in the CT Scan Room or the personnel outdoors cause radiating harm.
Further, described contactor compress switch for separating, electronic induction switch or light sensation switch.Above-described switch can reach door and cut out the effect of just connecting circuit under the situation fully, meets content of the present utility model.
Further, also comprise buzzer, described buzzer is connected with contactor, with the exposure switch in parallel.The effect of buzzer is to remind the people of the inside when the door of CT Scan Room is all shut, and prevents to can not get in CT Scan Room except that the personnel the person of being scanned the drawback of the feedback information of a Close All, reminds the CT scan indoor occupant in time to leave.
Further, described buzzer also is connected to one and is used to control the switch that buzzer stops to pipe; Or described buzzer can only pipe 3～5 seconds.Buzzer can be provided with a switch or adopt and stops the mode to pipe automatically on the working doctor platform, in order to avoid pipe for a long time the person of being scanned and doctor are impacted.
Description of drawings
Below in conjunction with the drawings and specific embodiments this utility model is described in further detail:
Fig. 1 is the structural representation of this utility model CT Scan Room safety device;
Fig. 2 is the circuit theory diagrams of this utility model CT Scan Room safety device.
The specific embodiment
In Fig. 1, the CT Scan Room safety device, the scanning room mainly is made up of operating room 1 and inspection chamber 2, the junction of operating room 1 and inspection chamber 2 is provided with the door 7 of lead glass dividing plate 5 and turnover operating room, described operating room inlet/outlet 7 is provided with contactor 8, also be provided with operating board 4 in the operating room 1, operating board 4 is provided with sudden and violent pass switch 3 and buzzer normally closed switch 10, be provided with the door 6 and the buzzer 9 of turnover inspection chamber in the inspection chamber 2, also be provided with contactor 8 on the door of turnover inspection chamber, described buzzer 9 is connected with contactor 8, in parallel with exposure switch 3, be connected with buzzer normally closed switch 10, buzzer can be the buzzer that stopped to pipe at 3～5 seconds, and described contactor 8 can be the decompress(ion) switch, electronic induction switch or light sensation switch.
Contactor 8 closures when the door 6 of turnover inspection chamber is closed with the door 7 of turnover operating room, buzzer 9 energized are sounded, play prompting and in inspection chamber 6, leave inspection chamber, and can play the prompting person of being scanned and carry out the effect of preparing of checking except that other personnel the person of being scanned; Operator just can guarantee in inspection chamber just to start when not having other personnel the person of being scanned the sound that buzzer normally closed switch 10 is closed buzzer, exposure switch 3 on the restart operation platform 4 carries out CT scan by the observation of lead glass dividing plate 5 to the person of being scanned.
Shown in Figure 2 is the circuit theory diagrams of CT Scan Room safety device, to connect to form series circuit by lead in parallel by the series circuit that lead connects to form with exposure switch 3 and CT machine 11 again for buzzer normally closed switch 10 and buzzer 9 among the figure, the circuit that back in parallel is formed is connected with two contactors 8 again, receive on the power supply again, buzzer 9 is sounded when two contactors, 8 closures, can play the prompting inspection chamber and leave inspection chamber except that the personnel the person of being scanned, in guaranteeing inspection chamber, the doctor disconnects buzzer normally closed switch 10 during no other staff, buzzer 9 stops to pipe and has avoided interference to checking, and the doctor restarts exposure switch 3 makes CT machine 11 begin the person of being scanned is scanned.
Above-described only is preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from this utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that this utility model is implemented.
