摘要： A patient demand valve (12) is automatically cycled open to provide selected volumes of oxygen at selected intervals. A pneumatic controller (10) connected to an oxygen supply provides a control pressure to operate the demand valve (12), with the cycling provided by pneumatic timers (38). The oxygen supply to the patient is also through the controller (10) to the demand valve (12). A tidal volume flow control valve (46) provides an adjustable flow rate when open. In one embodiment, the patient demand valve is in an assembly which includes a safety subassembly (326), which incorporates a signaling device that indicates an over-pressure condition in the assembly as a result of a blockage of gas flow to the patient, and also includes a anti-suffocation valve (336).

摘要： A portable, battery-powered aspirator for use in emergency situations having an improved fluid container incorporating a recess for coiling an aspiration hose within the structural outline of the aspirator housing. A connection grommet in the housing between the container and a vaccum pump in the housing includes a stepped throughbore to alternately mate directly with a tube from the container or a different size fitting of an intermediate filter. A removable baffle in an outlet port from the pump reduces noise and vapor discharge. The pump generates a high vacuum pressure and runs efficiently to extend the usable life of the aspirator. An improved recharging unit releasably retains the aspirator on a shelf by simply sliding the aspirator straight back on guide rails. Flexible recharging terminals in the unit automatically align with angle power prongs extending from the rear of the aspirator.

摘要： A demand valve resuscitator having a reduced manual flow control. The resuscitator connects between a source of pressurized gas and a breathing mask. A patient may draw a flow of gas on demand through the resuscitator by inhaling. A pressure-responsive diaphragm (48) within a pressure chamber (30), actuated on demand or manually, acts on a tilt valve (32) in a gas intake port (56). Alternatively, an attendant may supply a reduced flow of gas to a patient by depressing a manual control button (106), which tilts the intake valve. The manual control (106) of the gas flow is overridden by excess pressure within the pressure chamber (30) of the resuscitator, and the button (106) must be released to reassert manual control. A baffle plate (75) in the pressure chamber (30) provides a venturi assist to reduce pressure adjacent the diaphragm (48) to enable the patient to obtain maximum gas flow on demand with slight inhale suction. An anti-suffocation valve (144) allows the patient to breathe ambient air in the absence of a predetermined gas inlet pressure. The anti-suffocation valve is disposed in an intake assembly (24) having an inlet fitting (22) capable of swiveling without affecting the operation of the tilt valve.
