    • The present invention relates to a positive pressure ventilation device. Particularly, although not exclusively, a positive pressure neonate resuscitation device and a mobile bedside trolley comprising the same. The positive pressure ventilation device comprises a housing; an air inlet and a gas outlet, each located in said housing, said air inlet and said fluid outlet being in fluid communication; an oxygen concentrator, located between said air inlet and said gas outlet operable to receive air from said air inlet via said motorised pump and to increase the concentration of oxygen present in said fluid which is delivered to said fluid outlet;said oxygen concentrator comprising: a compressor having a motorised pump to draw air into said air inlet; two or more chambers, each containing a nitrogen adsorbent operable and to extract nitrogen from ambient air entering said two or more chambers to provide oxygen-enriched gas to said gas outlet; and at least one valve to alternate the flow of air between said two or more chambers; wherein the device further comprises means to regulate the frequency at which said at least one valve alternates the flow of air between said two or more chambers of said oxygen concentrator to alter the composition of gas delivered to the gas outlet. Wherein the composition of gas delivered to the device outlet is variable between ambient air and air supplemented with greater than 21 % O2.

    • An inflatable mattress for supporting patients comprises two inflatable longitudinal tubes (1, 2) extending along the respective longitudinal edges of the mattress and a plurality of inflatable transverse tubes (3, 3'). Each transverse tube (3 or 3') has adjacent its end an aperture (9a), with the longitudinal tube (1) extending through the aligned apertures (9a) at one side of the mattrress and the longitudinal tube (2) extending through the aligned apertures (9a) at the other side of the mattress. The transverse tubes are selectively inflatable in various modes under microprocessor control.
    • 用于支撑患者的可充气床垫包括沿着床垫的相应纵向边缘延伸的两个可充气纵向管道(1,2)和多个可充气的横向管道(3,3')。 每个横管(3或3')在其端部附近具有孔(9a),纵向管(1)延伸穿过垫子一侧的对齐的孔(9a),并且纵管(2)延伸穿过 在床垫的另一侧的对准孔(9a)。 在微处理器控制下,横管可以各种模式选择性充气。
