  • Patent number: 9022746
    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.

  • Publication number: 20140174443
    Abstract: One or more embodiments of the presently described invention provides a ventilator including a timing device, an electric power source and a flow control device. The timing device is electronically controlled and is capable of controlling a period of time that a fluid is delivered to a patient. The timing device can control this period of time using a solenoid. The flow control device controls a rate of flow that the fluid is delivered to the patient. The flow control device can control the rate of flow using a plurality of orifices. The timing device and flow control device are separate from one another and each is capable of being operated independent of the other.

  • Publication number: 20130055887
    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.

  • Patent number: 7530365
    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.

  • Publication number: 20070215158
    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.

  • Publication number: 20070103290
    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.
