Abstract: A compressor apparatus having a first compressor head for generating a first gas flow and a second compressor head for generating a second gas flow with a shuttling by-pass component in fluid flow communication between the first and second compressor heads for allowing the output of a portion of either the first gas flow or the second gas flow to be diverted to the other compressor head. The shuttling by-pass component allows a portion of the first gas flow to be diverted from the first compressor head to the second compressor head during an exhaust stroke of the first compressor head, while also allowing a portion of the second gas flow to be diverted from the second compressor head to the first compressor head during an exhaust stroke of the second compressor head in alternating sequence such that a more steady output of gas flow may be attained.

Abstract: A multiple valve compressor head having a casing defining an intake chamber in selective communication with a cavity through a plurality of one-way intake valves and an exhaust chamber in selective communication with the cavity through a plurality of one-way exhaust valves is disclosed. The casing further defines an inlet port for the entry of gas into the intake chamber and an outlet port for forcing out compressed gas from the exhaust chamber. In operation, the multiple valve compressor head is in operative engagement with a reciprocating diaphragm that draws the gas into the intake chamber and then the cavity during the intake stroke of the diaphragm, while expelling compressed gas from the cavity and through the outlet port during the exhaust stroke of the diaphragm.

Abstract: A surge prevention valve may be used to prevent the formation of an initial surge of high pressure. The valve may be located, for example, between a high pressure gas cylinder and a medical pressure regulator. The valve is provided with first and second valves located within a housing and integrating a pressurization orifice. The initial opening of the valve in an axial direction enables gas to flow through the pressurization orifice at a first flow rate. The full opening of the valve in the axial direction enables the gas to flow through the second valve at a second flow rate, which is much higher than the first flow rate. The controlled pressurization of the gas through the orifice delays the time during which the gas reaches full recompression. The valve may be further provided with a vent for venting pressurized gas away from a nominally closed top surface of the lower valve element.

Abstract: A mask restraining system used with a bag mask resuscitator for securely seating a mask on a patient's face is disclosed. The mask restraining system may include a retainer defining upper and lower slots adapted to engage first and second cords, respectively. The bag mask resuscitator may include hollow, flexible tubing having a distal end in communication with a resuscitation bag for forcing air through the flexible tubing and a proximal end in communication with a valve assembly that is rotatably engaged with the mask. The mask includes a port adapted to engage an aperture defined by the retainer in order to engage the mask to the retainer. The first and second cords may be engaged to the upper slots and lower slots, respectively, in order to securely seat the mask on the patient' face when the first and second cords are tightened relative to the retainer.

Abstract: A monitoring system to enable a facility to monitor variables for out-of-limit conditions and to signal in response to such an out-of-limit condition, including one or more monitoring panels or so-called alarm panels located for sensing one or more variables at one or more given location within a facility such as a hospital or laboratory to sense and respond to data associated with out-of-limit condition. The one or more panels recognize the existence of an out-of-limit condition so as to determine the nature of the out-of-limit condition, such as underpressure or overpressure, and provide the information regarding such condition so as to enable such a condition to be remedied. One or more panels are selectively provided with one or more circuit modules which can be selectively configured for sensing different conditions in the facility, and the modules provide an assembly of grouped modular configuration with each module monitoring multiple possible variables.

Abstract: A monitoring system including a computer system; a data converter connected to the computer system through a cable; one or more panels each connected to the data converter through one or more data lines; the one or more panels obtaining data by measuring a measurable component of a near or remote system. The computer system monitors the one or more panels to determine when an alarm condition exists and to provide data from the one or more panels.

Abstract: A bag mask resuscitator including flexible tubing having a proximal end and a distal end with the proximal end engaged to a resuscitation bag and the distal end adapted for engagement with a valve assembly is disclosed. The valve assembly includes a coupling member adapted for quick engagement and disengagement of the flexible tubing from the valve assembly using a simple action.

The valve may be located, for example, between a high pressure gas cylinder and a medical pressure regulator. The valve is provided with first and second valves located within a housing and integrating a pressurization orifice. The initial opening of the valve in an axial direction enables gas to flow through the pressurization orifice at a first flow rate. The fill opening of the valve in the axial direction enables the gas to flow through the second valve at a second flow rate, which is much higher than the first flow rate. The controlled pressurization of the gas through the orifice delays the time during which the gas reaches full recompression. The valve may be further provided with a vent for venting pressurized gas away from a nominally closed top surface of the lower valve element.

Abstract: A pressure regulator utilizing a gauge having rugged internal components. In one embodiment, the gauge has a low profile and is mounted to the regulator body. In another embodiment, the gauge is integral with the regulator body. In one preferred embodiment, the gauge includes a pressure pin and a bias, such as a spring. One side of the pressure pin communicates directly with the source pressure and is urged by the source pressure to move the pressure pin in a first direction, while the other side of the pressure pin is at a known pressure, such as ambient or atmospheric pressure, and is urged by the bias to move the pressure pin in a second direction opposed to the first direction. An indication of the position of the pressure pin is sensed by a user and is used to determine the source pressure or level. In one aspect, the indicator is a pointer or indicator mounted to move in response to movement of the pressure pin and mounted so that its position is visible (i.e., sensed by sight) to the user.
