Medical air mattress

摘要

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.

主权项

1. A medical air mattress comprising:
a lower bedspread having two sides, a front end, and a back end; two inclined air cells positioned longitudinally on the lower bedspread and extending parallel to one another between the front end and the back end of the lower bedspread, and positioned respectively near the two sides of the lower bedspread; a mattress body positioned across the inclined air cells, the mattress body comprising multiple body air cells and multiple head air cells parallel to each other and arranged in a row to form an air cell row, the head air cells are arranged at a head end in the air cell row, the body air cells and the head air cells are positioned non-parallel to the inclined air cells; an upper bedspread covering the mattress body and connected to the lower bedspread and having guardrail sleeves, respectively formed adjacent to the edges of two sides of the upper bedspread, each guardrail sleeve having at least one sleeve body; a guardrail unit mounted in the guardrail sleeves and comprising multiple guardrail air cells mounted respectively in the sleeve bodies of the guardrail sleeve; and, a pumping assembly to control inflating and deflating connected to and configured to selectively inflate the inclined air cells, the body air cells, the head air cells and the guardrail air cells independently from one another, the pumping assembly comprising: a pump; an inclined pipeline connecting the pump with the inclined air cells; an odd body pipeline connecting the pump with the body air cells and the head air cells at odd rows of the air cell rows; an even body pipeline connecting the pump with the body air cells and the head air cells at even rows of the air cell rows; a guardrail pipeline connecting the pump with the guardrail air cells, the guardrail pipeline is connected to a body alternating-valve such that air can only flow from the pump to the guardrail pipeline, the body alternating-valve is connected between the pump with the body pipeline and the guardrail pipeline, the multiple guardrail air cells are independently deflatable from the mattress body; and a rapidly releasing valve connected to the odd body pipeline and the even body pipeline.
