Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a finger-clip monitor for radiotherapy. Background Art

[0002] Radiotherapy is one of the three major means of cancer treatment. 80% of cancer patients need radiotherapy. Due to the high dose of radiation in radiotherapy, it will cause great harm to non-treatment personnel. Therefore, during the treatment process, only the cancer patient can be left in the radiotherapy room, and the operator in the control room can only observe the patient's limb movements from a distance through the camera to judge the patient's physical condition. It is impossible to directly monitor the patient's vital signs, such as ECG waveform, blood oxygen saturation and other vital signs, which poses a great safety hazard. Therefore, we propose a finger clip monitor for radiotherapy to solve the above problems. Utility Model Content
