Abstract: A blood pressure system that includes a compact monitor housing that contains a pneumatic circuit and an electrical circuit and a processor for inflating and deflating a cuff to provide blood pressure related data. A split connector allows the housing to interface both pneumatically and electronically with one or more independent cuffs and/or with one or more host stations. Each host station contains a dependent cuff and further electrical components to expand and enhance the systems output of related blood pressure data that is generated by either the independent or dependent cuffs.

Abstract: Adaptive attachments used in combination with a blood pressure cuff enable various blood pressure measurements to be taken in a hospital or other setting having various single and/or dual lumen manual or electronic blood pressure measuring equipment with a single patient-worn cuff.

Abstract: A blood pressure measurement apparatus for use in association with a blood pressure measuring cuff includes a housing having an upper shell and a lower shell defining an interior chamber and a replaceable module disposed within the interior chamber. The replaceable module houses a pump for inflating the blood pressure measuring cuff and a vent valve for venting the blood pressure measuring cuff. A cuff pressure sensor is provided within the interior chamber, either within or externally of the replaceable module. A control circuit for controlling the pump and the vent valve is provided on a circuit board disposed externally of the replaceable module. A power pack may be provided within the replaceable module for supplying electric power to the pump, the valve, the control circuit and other components within the interior chamber.

Abstract: A blood pressure monitoring system that includes a compact housing that contains a pneumatic circuit that is removably attached to an inflatable cuff by a hoseless connector so that the cuff can be inflated and deflated to provide blood pressure readings that are detected by a pressure sensor. A controller is also contained in the housing which controls the circuit activities and records blood pressure related data. The controller is linked via a bidirectional communication system with a processor that is contained in a host station which programs the controller and collects and records blood pressure related data. The communication system also allows the monitoring system to communicate over a wider network with other remote stations.

Abstract: The invention relates to a blood pressure monitor for measuring the blood pressure of a person including a blood pressure cuff. The blood pressure monitor also includes an electro-pneumatic package. The electro-pneumatic package includes a pump, a valve, a pressure sensor, and one or more accelerometers. A pneumatic mechanical coupling is configured to pneumatically and mechanically directly couple the blood pressure cuff to the electro-pneumatic package, wherein a signal from the one or more accelerometers configured to indicate an activity level of the person during a blood pressure measurement. A display is configured to display an indication of the activity level. The invention also relates to a blood pressure monitor wherein an electronics circuit is configured to receive the motion signal from the one or more accelerometers during a blood pressure measurement. The invention also relates to a method for detecting a motion artifact in a non-invasive blood pressure measurement.

Abstract: A pressure measuring apparatus includes a gage that is at least partially imbedded within a flexible elastomeric member disposed within an interior cavity of a device housing. A shock resistant member into which the gage is inserted permits fluid interconnection between the interior of the gage having a contained movement mechanism that is responsive to fluid pressure changes and a fluid source, such as an inflatable blood pressure cuff and further provides shock and/or impact resistance for a contained movement mechanism. Additional impact/shock absorption is provided by exterior features of the apparatus, including a peripheral bumper having a plurality of raised spring-like protrusions, and rubberized and contoured features of the device housing.

Abstract: A blood pressure measuring apparatus includes an inflatable cuff which can be wrapped about the limb of a patient. The sleeve includes a sealed interior capable of inflation, and an integrated inflation/measuring device. The integrated device is an elastomeric enclosure which retains a gage and a pneumatic bulb therein and hosing for fluidly interconnecting the pneumatic bulb, the inflatable cuff, and the gage.

Abstract: A heater for an indirectly heated vacuum tube cathode is formed of anisotropic pyrolytic graphite in which current passes through the graphite in the "c" direction.

Abstract: Apparatus for jumpering a first battery to a second battery. First and second jumper cables are connected to terminals of the batteries, each jumper cable being connected between corresponding polarity battery terminals to form an electrical path therebetween. A normally open set of contacts of a relay are series-connected with one of the jumper cables to hold the circuit path between the batteries open while the cables are being connected. This prevents the creation of sparks at the terminals of either battery. The relay is energized after the cables are connected to close the contacts and complete the circuit path between the batteries whereby one of the batteries may supply power to a load normally supplied by the other battery. The set of contacts are enclosed to prevent any sparks created during closure of the contacts from igniting any gases generated by the batteries.
