Abstract: An end portion of a patient transport cot having a collapsible undercarriage is elevated by a lift device including a collapsible frame on caster wheels and supporting a power operated lift member. A head member is mounted on the lift member and supports adjustable hook members which releasably engage an end portion of the frame of the transport cot. In one embodiment, the lift member includes a fluid cylinder operated from a fluid supply tank through a control valve. In other embodiments, the lift member is operated by an electric motor driven mechanical actuator controlled by a switch. A support bracket provides for conveniently mounting the lift device on a door of a transport vehicle for storage.

Abstract: A disposable physiological fluid warmer formed as a small compact box which may be attached to a patient's arm. The warmer includes two chambers within the box containing a heat exchanger element constructed from a continuous length of stainless steel tubing in the form of two parallel coils which are connected to one another by a straight length of tubing. A passage is provided along one side of the box between the chambers such that a warming fluid may be introduced through an aperture in the box into one of the chambers, flow into the other chamber, and then exit the warmer through another aperture in the box. A physiological fluid to be warmed is supplied to the coils through a first flexible plastic inlet tube and discharged for infusion into a patient through a second flexible plastic tube. The second tube has a length of less than one foot in order to minimize the amount of heat lost from the fluid as it travels from the warmer to the patient.
