Abstract

The invention relates to the field of medical instruments, and particularly relates to an alarm circuit for preventing outsiders from entering an X-ray machine room. The alarm circuit for preventing outsiders from entering an X-ray machine room can automatically detect whether a person intrudes into the X-ray machine room or not, and effectively prevents X-rays from hurting people. According to the technical scheme, the alarm circuit for preventing outsiders from entering the X-ray machine room comprises a power supply circuit, a first key, an electronic switch circuit, a first indicator lamp circuit and the like; and the first key is connected with the input end of the electronic switch circuit, the input end of the first indicator lamp circuit is connected with the output end of the electronic switch circuit, and the output end of the electronic switch circuit is connected with the input end of the first infrared detection module. Through the action of a light emitting diode VD1, the medical staff can know that the alarm circuit for preventing outsiders from entering the X-ray machine roomstarts working.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an alarm circuit for preventing outsiders from entering an X-ray machine room. Background technique [0002] X-rays are mainly used in the initial screening of patients' chest, bone joints or lungs and other diseases, but X-rays also have certain side effects on the human body. If the X-ray exposure time is too long, it will cause certain damage to people's bodies. Therefore, when the patient is taking X-rays, it is necessary to prevent other people from intruding into the X-ray machine room, so as to avoid causing harm to people's bodies. [0003] However, the work of the hospital is relatively busy, and the medical staff cannot always pay attention to whether other people break into the X-ray machine room. If special medical staff are arranged to guard the X-ray machine room, when the guarding of the X-ray machine room takes too long It will produce a sense of fatigue and drow...
