Abstract

The invention discloses an intelligent turning bed for bedridden patients, which relates to the technical field of medical equipment and comprises a bed body, a left-right adjusting mechanism, a fabric plate and a supporting mattress, wherein a worm and gear system is driven by a motor to realize the lifting of the left part and the right part of the bed surface, so that the smooth turning of the patients is assisted, and the labor intensity of nursing staff and the risk of pressure sores caused by improper turning are obviously reduced. The integrated perception module, the processing and control module, the man-machine interaction module and the power module in the support mattress adopt the film piezoresistive sensor to monitor the pressure of the key parts of the body surface of the patient in real time, combine the multilevel threshold algorithm to evaluate the risk of the pressure sore, and send out audible and visual alarm when the risk is high, remind the nursing staff to intervene in time. The system realizes the intelligent transition from passive nursing to active prevention, has the advantages of reasonable structure, simple and convenient operation, accurate early warning and the like, and is suitable for clinical nursing scenes of long-term bedridden patients.
