Patient rehabilitation bed with wound surface adhesion prevention function

The invention provides a patient rehabilitation bed with a wound surface adhesion prevention function, and relates to the technical field of rehabilitation beds. Micropores communicated with an inner cavity of the mattress are uniformly distributed in the top end surface of the mattress; an air blower is installed in the left side of the rectangular supporting frame and electrically connected with the control box, an air outlet of the air blower is communicated with an inner cavity of the mattress through an air conveying pipeline, and after the air blower is started, air flow generated by the air blower is input into the inner cavity of the mattress through the air conveying pipeline and diffused out through the micropore part. Air flow separation is conducted on the contact portion of the skin of a patient and the mattress, adhesion caused by long-time contact is avoided, the wound area is prevented from being dragged during follow-up movement, and the problems that when the patient lies on the bed for recu
