  • An air mattress or airbed is a mattress or sleeping pad consisting of one or more inflatable cells or tubes and may generally be categorized into a general purpose air mattress and a medical air mattress.
  • the medical air mattress is particularly suitable for a bedridden patient as it relieves local stress concentration and prevents bedsores.
  • an air mattress set generally comprises a mattress main body, a gas supplier and a gas communication device.
  • the mattress main body has one or more air tubes.
  • the gas supplier comprises an air pump with adjustable air supply and discharge settings.
  • the gas communication device is arranged between the mattress main body and the gas supplier to form air communication between the mattress main body and the gas supplier, such that the gas supplier can inflate or deflate the mattress main body to adjust the hardness/softness of the mattress main body.

  3. Die Gasversorgungsanordnung (100) nach Anspruch 1, wobei die Gaskommunikationsvorrichtung (10) relativ zum Gasversorger (20) zwischen einer ersten Ausrichtung (A) und einer zweiten Ausrichtung (B) schaltbar ist, und wobei die Gaskommunikationsvorrichtung (10) luftdicht an den Gasversorger (20) an der ersten Ausrichtung (A) angeschlossen ist und das Kupplungsglied (3) von der Kupplungsstruktur (22) an der zweiten Ausrichtung (B) ausgekuppelt ist.
  4. Eine Gasversorgungsanordnung (100) nach Anspruch 3, wobei die Kupplungsstruktur (22) einen oberen Kupplungsteil (221) und einen unteren Kupplungsteil (222) umfasst, das Gehäuse (11) eine obere Öffnung (16) und eine untere Öffnung (17) umfasst, die dem oberen Kupplungsteil (221) bzw. dem unteren Kupplungsteil (222) entsprechen, und wobei das Kupplungsglied (3) beweglich angeordnet ist, um die Einkupplung oder Auskupplung des oberen Kupplungsteils (221) und des unteren Kupplungsteils (3) durch die obere Öffnung (16) zu ermöglichen.
  5. Die Gasversorgungsanordnung (100) nach Anspruch 4, wobei an der ersten Ausrichtung (A) der obere Kupplungsteil (221) mit dem Kupplungsglied (3) durch die obere Öffnung (16) und der untere Kupplungsteil (222) mit dem Gehäuse (11) durch die untere Öffnung (17) eingekuppelt ist, und wobei an der zweiten Ausrichtung (B) der obere Kupplungsteil (221) vom Kupplungsteil (3) ausgekuppelt ist und der untere Kupplungsteil (222) beweglich mit dem Gehäuse (11) eingekuppelt ist (B).
  6. Die Gasversorgungsanordnung (100) nach Anspruch 1, wobei der Kupplungsteil (3) elastisch mit dem Gehäuse (11) verbunden ist.
  7. Die Gasversorgungsanordnung (100) nach Anspruch 1, die ferner ein manipulierbares Teil (5) zur Aktivierung des Kupplungsglieds (3) enthält.
  8. Die Gaskommunikationsvorrichtung (10) nach Anspruch 7, wobei das manipulierbare Teil (5) ein Druckknopf (51) ist.
  9. Die Gaskommunikationsvorrichtung (10) nach Anspruch 1, wobei das Freigabeglied (7) ein elastischer Stift ist.
  10. Die Gaskommunikationsvorrichtung (10) nach Anspruch 1, wobei das Freigabeglied (7) mindestens teilweise im Gehäuse (11) angeordnet ist.
  11. Ein Verfahren zum Einstellen der Gasversorgung für eine Luftmatratze in der Gaskommunikation mit einer Gasversorgungsanordnung (100), die einen Gasversorger (20) und eine Gaskommunikationsvorrichtung (10) enthält, wobei das Verfahren in der Auskupplung der Gaskommunikationsvorrichtung (10) vom Gasversorger (20) besteht, sodass sich das Freigabeglied (7) verformen kann, um die Auskopplung der Gaskommunikationsvorrichtung (10) vom Gasversorger (20) zu fördern.
