PNEUMATIC PRESSURE CONTROL DEVICE FOR PRESSURE ULCER PREVENTION MATTRESS

摘要

PURPOSE: A pneumatic pressure control device for Pressure Ulcer Prevention mattress is provided to set pneumatic pressure supplied to each aircell based on the body information showing the physical state of user.;CONSTITUTION: A mattress comprises: a control unit (100) of a pneumatic pressure control device for Pressure Ulcer Prevention mattress; a pneumatic pressure setting unit (110) setting up the pneumatic pressure standard mode of each aircell (20); a computation and the DB module (120) determined the air pressure information of each aircell is stored; an operation mode control part (130) controlling the operation of the solvalve (40) and pump for air compressed (50); a pneumatic pressure measurement module (121) about each aircell in which the body of user contacts at the upper part of the air matrix (10); a DB module records the base pressure information the primary volume pressure of the divided aircell inside through the pressure measuring sensor (30). And the pneumatic pressure displacement module (122) which is based the fixed pneumatic pressure with the pneumatic pressure measurement module and measures the air pressure change amount according to the time variation and the pressure displacement. The air pressure control module (123) which transmits the signal in the operation mode control part in order to control the pneumatic pressure with the pneumatic pressure displacement module in the aircell (20) corresponding to the fixed pressure displacement and controls the pneumatic pressure is included.;COPYRIGHT KIPO 2013;[Reference numerals] (110) Pneumatic pressure setting unit; (120) DB module; (121) Pneumatic pressure measurement module; (122) Pneumatic pressure displacement module; (123) Air pressure control module; (130) Operation mode control part; (20) Aircell; (30) Pressure measuring sensor; (40) Solvalve; (50) Pump for air compressed
