Description

TECHNICAL FIELD

[0001] The application relates to a sickbed device, in particular to a movable sickbed. BACKGROUND

[0002] Before operation, a patient needs to be transferred to an operation trolley and then to an operating room. Some critically ill patients cannot complete the transfer process by themselves. After operation, the patient needs to be transferred from the operation trolley to the sickbed. During operation, the patient needs to be anesthetized, and the patient's limbs are weak after waking up from anesthesia, so the patient cannot complete the transfer process by himself. In the above process, manpower is often used to transfer the patient. During the transfer, multiple people need to cooperate to carry the patient. Due to the synchronization of manpower, the patient is easy to be injured again during the transfer process. Especially for some critically ill patients, secondary injury will directly affect the subsequent treatment or operation effect. If the patient has a tube or instrument inserted in the body, it is not convenient to move. In the invention patent with the application number CN202011207784.7, a movable sickbed device is disclosed, which comprises a fixed sickbed, a movable bed and a transfer plate.
