초록 ▼

A resuscitation and inhalation device which can be used alternatively in each of two modes. The flow of oxygen or gas is controlled by a control valve, itself controlled by a movable member acted upon by the pressure of oxygen or gas in a chamber after having flowed past the control valve. On meeting a preset maximum pressure, the valve member moves to close the control valve. The movable valve member is acted upon by a magnetic field which is adjustable, and the magnetic field strength sets the pressure at which the valve member moves. Oxygen or gas is admitted to the control valve by two alternative inlet valves, one for resuscitation with only oxygen or gas flowing through the mask, and one for inhalation, with a mixture of oxygen or gas and air or a second gas being fed through the mask.

대표청구항 ▼

A resuscitation and inhalation device, comprising: a chamber, a gaseous flow control valve to control flow of a gas to said chamber and a first magnetic member associated with said gaseous flow control valve; a movable valve member, acted upon by pressure of gas in said chamber, said movable valve member including a further magnetic member, said movable valve member being biased to act on said gaseous flow control valve to move it to an open position; one of said magnetic members being magnetized, the magnetic field of the magnetized member acting upon the other magnetic member to restrain movement of said movable valve member by said pressure of gas in said chamber; alternate first and second gaseous inlet valves for admitting a first gas under pressure to said gaseous flow control valve; operation of a first of said alternate inlet valves permitting flow only when manually held in an actuated position; operation of a second of said alternate inlet valves permitting continuous flow of gas to said gaseous flow control valve; a mixing chamber; gaseous access means for admitting a second gas to said mixing chamber; and seating means associated with said first alternate inlet valve for closing said gaseous access means on operation of said first inlet valve, whereby on operation of said first inlet valve, said first gas can flow to a connector for flow to a mask, and on operation of said second alternate inlet valve, said first gas is mixed with said second gas in said mixing chamber prior to flowing to said connector and to said mask.
