Medical apparatus with protection device

Abstract

The invention discloses a medical device with a protective device, which comprises a movable treatment table and a protective ring. The protective ring is fixed on the treatment table; the protective ring comprises an outer ring, an inner ring, a sensor and a first elastic mechanism, wherein the sensor and the first elastic mechanism are arranged between the outer ring and the inner ring; and the protective ring also comprises a pin shaft arranged on one of the outer ring and the inner ring and a chute arranged on the other one of the outer ring and the inner ring, wherein the pin shaft is extended into the chute and can slide in the chute. The protective ring is provided with the pin shaft, and the touch from each direction drives the outer ring to rotate around the pin shaft or drives the pin shaft to slide along the chute, so the protective ring can effectively trigger the sensor to generate signals to make the device enter a protection state so as to ensure the safety of a patient.

Description

technical field [0001] The invention relates to a medical device, in particular to a medical device with a protective device. Background technique [0002] Radiation therapy equipment includes a ray radiation device, a three-dimensional moving treatment couch and a positioning couch fixed on the treatment couch. When the radiotherapy system is used for radiotherapy, the patient is positioned on the positioning couch. With the three-dimensional movement of the treatment couch, the ray radiation device The emitted ray beams are concentrated in different treatment areas of the patient, and the ray radiation device rotates around the treatment bed to achieve fully automatic radiation therapy. Due to the limitation of radiation nuclear physical characteristics and radiation protection, the treatment space is designed within a certain range. The advanced ray radiation device may squeeze the patient, and there is a potential safety hazard. Contents of the invention [0003] The ...
