An auto-occlusion safety device is provided for use in preventing rupture of infusion components during rapid infusion procedures. An occlusion valve is disclosed having a threshold pressure that is less than a rupture tolerance of the infusion system components. As the fluid pressure of the infusion system increases beyond the threshold pressure of the occlusion valve, the occlusion valve is automatically activated thereby occluding fluid flow upstream from a vulnerable infusion component. An accumulator is further disclosed for use in combination with the safety device to compensate for time delays in full activation of the occlusion valve.

The invention discloses a portable pressurized infusion device which comprises an elastic plate curled in an Archimedes spiral shape, a long-strip-shaped elastic liquid bag adheres to the interior of a spiral gap of the elastic plate in the length direction, and the liquid bag is communicated with an infusion tube. After liquid medicine is injected, the liquid bag expands to enable the elastic plate to be unfolded to be in a logarithmic spiral shape, and constant-pressure infusion is achieved by continuously extruding the liquid bag through elastic restoring force. A sealing mechanism and a self-sealing liquid injection head are arranged on the infusion tube, so that rapid liquid injection and safe liquid stopping are facilitated. The device is compact in structure, does not need a power supply or an inflating device, is simple and convenient to operate, and is suitable for rapid infusion treatment in environments with limited electric power and human resources, such as disaster rescue and mobile medical treatment.
