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: <20VA VII. Working conditions: 1, bad environment temperature: 5-40 °C; 2. Relative humidity: <85% 3, power conditions: 220V ± 22V, 50hz Eight, use method: 1. Place the air mattress on the sickbed or single bed (the surface of the bed surface cannot be pointed or hard to prevent the air cushion from being damaged) so that the air intake hole is located on the patient's foot; 2. Take the air pump out of the foam box, according to the situation, it can be placed on the desktop or under the bed with a solid position more than 20cm above the ground, and the use environment should be clean and dry; 3. Turn on the air pump power, turn on the power switch, and turn the pressure adjusting knob clockwise to the maximum state. The air outlet of the air pump has gas discharge, which is suitable for single pump air pump; 4. Connect one end of the airway tube to the air nozzle on the mattress, and connect the other end to the air outlet on the right side of the air pump. The connection should be firmly in place and no air leakage can occur. 5. The air mattress enters into the inflation work state. After inflating for 15-20 minutes, the pressure in the air bed can reach the normal state of use. If necessary, a bed sheet can be laid on the air mattress and the patient can be moved to the air cushion according to the needs of the patient. Adjust the air pump pressure adjustment knob to change the softness of the air heat; 6. Unfasten the snaps on both sides when you are in urine and excretion, and open the small air cushion at the hole. Then you can use it conveniently. Then return to the original position to restore the fluctuating state. 7, according to the needs of the patient can be used for 24 hours continuous inflation, or use as directed Nine, contraindications: Anti-decubitus gas bed has a thermal fluctuation function, the fracture surgery can not use this product. Tenth, safety precautions: 1.
