  • Patent number: 10172754
    Abstract: A medical air mattress has a mattress body and an upper bedspread. The mattress body is formed by multiple air cells including independent air cells parallelly arranged as an air cell row. The upper bedspread covers the mattress body. The independent air cells are connected to the independent deflating unit to be deflated independently. When the patient needs to use the bedpan, the independent air cells are deflated to form a recess for receiving the bedpan so that the patient needs not to move.

  • Patent number: 9566202
    Abstract: A medical air mattress has a mattress body, a lower bedspread and an upper bedspread. The mattress body is formed by multiple air cells substantially parallel arranged in a row forming an air cell row. The upper bedspread covers the mattress body and is securely connected to the lower bedspread. The mattress further comprises a pumping assembly with a pump and at least a pipeline connecting the pump with the air cells such that inflating and/or deflating of the air cells is controllable selectively.

  • Patent number: RE47680
    Abstract: A medical air mattress has a mattress body, a lower bedspread, an upper bedspread and a guardrail unit. The mattress body is formed by multiple air cells parallel arranged in an air cell row. The upper bedspread covers the mattress body and has two guardrail sleeves formed on the upper bedspread. The guardrail unit has multiple guardrail air cells mounted respectively in the guardrail sleeves. Since the guardrail sleeves are formed on the upper bedspread, the guardrail sleeves from each opposite side of the upper bedspread will draw each other to maintain the guardrail sleeves in position when pressed. Therefore, the guardrail sleeves do not fall down when pressed to remain providing optimal protection purpose.
