Definitions
- Method and apparatus for rapidly inflating an inflatable chamber in particular a chamber of a support device, such as a mattress.
- the present invention provides a method of rapidly inflating an inflatable chamber with an inflation fluid, said chamber having a given inflation volume, comprising a step of inflating said chamber to a predetermined inflation pressure. , characterized in that the inflation itself is carried out in two stages, a first stage known as rapid inflation at high flow rate and at low pressure to fill the volume of said chamber essentially completely, and a second stage of inflation at low flow rate but at high pressure to obtain said predetermined inflation pressure in said chamber.
- the aforementioned chamber is part of a support device, in particular for supporting the body of a patient, this support device comprising preferably a mattress.
- the large flow rate used for rapid inflation of the first step is carried out at a flow rate equal to or greater than 50 l / min, better equal or greater at 100 l / min, more preferably still more than 200 l / min and more preferably still more than 300 l / min.
- the aforementioned second inflation means at low flow rate at high pressure comprises at least one compressor, for example of the membrane vibrator type delivering a flow rate of the order of 10 l / min at a pressure of the order of 40 mbar to obtain a predetermined pressure in the chamber of the order of 20 mbar, advantageously in air.
- the rapid inflation of the chamber during the first stage is preferably obtained in an extremely short time of the order of 1 min and the pressurization to the predetermined pressure with the second inflation means, such as that a compressor is produced in an equally short time of the order of 1 to 4 min, which results in a total inflation time at the predetermined inflation pressure of less than 5 min.
- the cushions or tubes can be deflated alternately individually, sequentially, in particular one in two, one in three, one in four or one in n. It is thus understood that the invention finds application in any type of inflatable chamber.
