Abstract

A manually operated resuscitator is provided. The resuscitator has an inner member provided in an outer member. The inner and outer members have an arrangement of apertures and valves to enable ambient air to be drawn into the pump in its non-pressurizing stroke and on a pressurizing stroke the inner member is capable of discharging air. The pump is connected to a mask by a rigid conduit. The face mask is positionable over the nose and mouth of a patient so as to form a fairly airtight seal with the face of the patient. An exhale aperture is provided adjacent the face mask which enables the patient to exhale air to the exterior of the device. The dimensions and configuration of the pump and conduit are suitable for human resuscitation purposes. Furthermore, the construction is such that the user of the device can hold the mask with one hand and the outer cylindrical member can be held and reciprocated by the other hand of the user so that when ambient air is pumped from the pump to the face mask, an increased pressure is applied to the mask so as to enhance the seal between the mask and the face of a patient.
