This 20 cm high mattress can entirely replace a common mattress. The air cell pressure is automatically adjusted and does not exceed the medium capillary pressure of 25 mmHg. The Dynamic TubusAir 18/3 is composed of 18 transversal inflatable air cells, which inflate and deflate in alternating intervals. The dynamic treatment therapy is alternating in every 3rd air cell. The treatment cycle can be set between 20 and 60 minutes. Each air cell is separately attached to the basis; if one air cell is damaged, it can be easily replaced with a new one. The mattress includes a 5 cm thick foam pad. The mattress cover is made of high-quality elastic incontinence-proof material, which prevents fluid penetration; however, the material is breathable and permeable to moisture. The mattress is equipped with a CPR valve for a rapid deflation in emergency situations such as resuscitation. If the patient has to be transported elsewhere, the mattress remains inflated for several hours after being disconnected from power supply. The mattress is suitable for patients with body weight from 20 to 200 kg.
