Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a transfer bed. Background Art

[0002] When rescuing some emergency patients, it is necessary to keep the patients in a specific position. For example, for patients with acute heart failure, the patient's position must be adjusted first, and the patient's legs must be allowed to hang down to reduce venous return, reduce the heart load, and relieve symptoms such as dyspnea. The best position for rescue may also be different in different conditions. Given that critically ill patients have rapid changes in their condition, certain uncertainties, and unpredictability, rescue often requires the patient to switch positions quickly in a short period of time due to changes in their condition, and critically ill patients often need to be transferred during in-hospital diagnosis and treatment. If during rescue, the nursing staff moves the patient from a lying position on the bed to a position with legs hanging down on a chair, or moves the patient from a position with legs hanging down on a chair to a lying position on the bed according to the patient's real-time condition and transfer requirements, the operation is time-consuming and laborious, which may easily delay the best time for rescue. In addition, since patients undergoing rescue often need to be connected to multiple types of emergency equipment, the convenience and efficiency of moving the patient will be affected, and moving the patient during rescue may easily aggravate the patient's discomfort.
