Problems solved by technology

[0002] At present, the sickbeds used in hospitals have single functions and can only be used for patients to rest in bed. Although more advanced sickbeds also have backrest lifting mechanisms, the handwheels are set at the feet of the sickbed. To make the patient sit up, the nursing staff must walk to the sickbed. When the patient sits up, the nursing staff cannot touch the patient, and the patient has no sense of security. At the same time, the existing lifting mechanism has a complex structure, the length of the screw rod is too large, the cost is high, and it is not easy to use. convenient
