First, the product name: Anti-decubitus mattress Second, the scope of application: This product is suitable for bedridden patients, to prevent patients from acne due to long-term bed. Third, the product structure consists of: This product is composed of inflatable cushion and air pump. The inflatable cushion is made of high frequency heat-sealable PVC cloth. It has a spherical air chamber. The air pump is connected to the inflatable cushion through joints, air pipes, air inlets, etc. Inflate the air chamber. V. Working principle: Through the inflator pump, the odd and even air chambers of the inflatable cushion are alternately filled and deflated, so that the patient's body bed part is in intermittent contact with the cushion surface to achieve an anti-acne effect. When the inflation pressure reaches 3 kPa, the cushioned micro-jet holes are evenly distributed. Emissions of gases outside the body improve air circulation under the body of the patient and enhance anti-acne effects. Sixth, the main technical indicators: 1, when filling and deflation: single pump air pump inflation 5min 5%, deflation 5min 5%, dual pump air pump 9min 5%, deflation 9min 5%; 2. Inflatable air pressure: 12kPa 0.5kPa (can be adjusted between 0 and maximum air pressure); 3, the most weight bearing: 120kg; 4, working noise: 24h 6. Inflatable pump power consumption:
