  • Patent number: 8528547
    Abstract: A respiratory therapy device including a housing, a flow diverter structure, a high frequency pressure port (HF port), and an entrainment port. The housing defines a primary passageway having a patient interface side. The flow diverter structure is in fluid communication with the primary passageway and is characterized by the absence of a venturi tube. The HF port is configured for fluid connection to a source of oscillatory gas flow, and is fluidly associated with the flow diverter structure. The entrainment port is openable to ambient air, and is fluidly associated with the flow diverter structure. With this construction, the device is configured such that flow characteristics of gas flow from an external source are altered upon interacting with the flow diverter structure to create a pressure drop for drawing in ambient air through the entrainment port in delivering a percussive pressure therapy to the patient side.

  • Patent number: 8529576
    Abstract: A curable material delivery cannula device and method are disclosed. The device includes a cannula and a hub. The cannula includes an open proximal end, a deflectable segment forming a pre-set curve, a lumen, and side orifice(s) adjacent, and proximally spaced from, the distal end and fluidly connected to the lumen. When inserted within a guide cannula, the deflectable segment straightens. When distally extended from the guide cannula, the deflectable segment reverts to the curved shape, which may be used to create a void in the bone for receiving curable material. The distal end has a blunt tip for non-traumatic interface with bodily material. During use, curable material, such as bone cement, is delivered from the side orifice(s) in a radial direction relative to the lumen.

  • Patent number: 8523839
    Abstract: An intravenous fluid pump (IV) contains a disposable part including a fluid chamber having a resilient top membrane and a non-disposable part including a piston abutting a resilient membrane and a vacuum chamber fitted on top of the resilient top membrane. An external pump is used to create vacuum in the vacuum chamber, resulting in the resilient top membrane being held taut. The flow rate through the pump is relatively independent of changes in the pressure of IV fluid on the upstream and the downstream due to changes in the relative elevation of the fluid reservoir and the patient with respect to the fluid pump.

  • Patent number: 8522780
    Abstract: A portable ventilator uses a ROOTS-type blower as a compressor to reduce both the size and power consumption of the ventilator. Various functional aspects of the ventilator are delegated to multiple subassemblies having dedicated controllers and software that interact with a ventilator processor to provide user interface functions, exhalation control and flow control servos, and monitoring of patient status. The ventilator overcomes noise problems through the use of noise reducing pressure compensating orifices on the ROOTS-type blower housing and multiple baffling chambers. The ventilator is configured with a highly portable form factor, and may be used as a stand-alone device or as a docked device having a docking cradle with enhanced interface and monitoring capabilities.

  • Patent number: 8511638
    Abstract: A connector is disclosed that has a housing having a fluid path from a first port through an internal cavity to a second port. The connector also includes a plug that has first and second positions within the internal cavity, where the plug blocks the fluid path between the first port and the internal cavity when in the first position. The plug has a diaphragm that separates the internal cavity into a first volume that is vented and a second volume that includes the fluid path. The plug also includes a biasing element that is disposed within the first volume and that urges the plug toward the first position. Displacement of the plug from the first position toward the second position opens the fluid path and increases the second volume.

  • Patent number: 8505871
    Abstract: An electrically activated access valve arrangement having a male connector, a female connector, and a valve. In certain embodiments, the male connector includes a conductive element, and the female connector includes contacts. Insertion of the male into the female connector completes a circuit and sends an electrical signal to the valve. This transitions the valve from the normally closed position to the opened position. In certain embodiments, the male connector has a connection port that connects to a connection port of the female connector. A pump, such as an infusion pump, sends an electrical signal through the connection ports, which causes the valve to transition from the normally closed position to the opened position. The electrically activatable valve of the connectors is prevented from opening if mated with conventional male and female luers.

  • Patent number: 8506552
    Abstract: An automatic pump relay system includes controllers coupled to drivers for sequentially discharging fluid from a plurality of medication containers into a coupler having a reflux barrier from which fluid is administered to a patient. The internal fluid pressure of the coupler is determined by a pressure sensing device or devices that provide signals to the controllers that, based at least on the sensor signals, cause the drivers to operate in reverse and forward directions so as to rapidly decrease and raise the fluid pressure within the coupler during a relay from an empty syringe to a filled syringe, thereby avoiding bolus formation and an interruption in infusion therapy. Independently operable syringes pumps are contemplated to be connected in relay fashion to form a modular system. An associated method is also disclosed wherein a fluid administration pressure is stored for use as a reference during a syringe changeover.
