An RFID reader is configured to be worn on the arm of a user and includes a housing with a bottom surface for facing the arm of a user and a top surface facing away from the arm. A securement structure engages the arm of the user to secure the housing. An antenna is mounted within the housing and is angled with respect to the bottom surface of the housing for providing an RF field at an angle to the arm of a user to direct the RF field toward an item held by the arm. The antenna includes an indexing structure with multiple angular positions for orientation of the antenna. A key structure is positioned in the housing and configured for engaging the indexing structure at an angular position around the antenna to orient the antenna at a desired rotational orientation in the housing to tune the antenna. Grip structures are formed along the top surface of the housing for gripping an item held by a user that contains an RFID tag that is read by the RFID reader.

A user interface for a pulse oximetry device that calculates physiologic parameters of a subject including at least a subject's heart rate and SpO2, is disclosed wherein the interface comprises a graphical display of at least one raw data signal of the pulse oximetry device that maintains heart and breath rate components and a display of the calculated heart rate and SpO2 of the subject. The interface may further include a user selectable data averaging function in which the interface is configured to selectively obtain and display averages of at least some of the calculated physiologic parameters over a defined period. The interface may further include a user selectable noise suppression function for the displayed data.
摘要:
The present invention pertains to a pressure support system in which a flow or volume of gas is measured without using a dedicated flow element used in a conventional flow meter. Instead, the present invention provides a tortuous gas flow path in which a pressure differential is created between two points in the tortuous path. This pressure differential created by the gas flow path provides the necessary pressure drop for measuring the gas flow and/or gas volume passing through the pressure support system.

A humidifier for use with a pressure support system. The humidifier includes a body having an inlet, a fluid holding chamber, and an outlet. The inlet is positioned upstream and in fluid communication with the fluid holding chamber. The outlet is positioned downstream of and in fluid communication with the fluid holding chamber. A back-flow preventing valve is positioned upstream of the fluid chamber. The back-flow preventing valve is movable between an open position, in which the inlet is unblocked, and a closed position in which the inlet is blocked. In the closed position, the back-flow preventing valve prevents fluid, fluid vapor, or both from entering the pressure support via the inlet to the humidifier.

A restraining tube for small animals (preferably animals with tails) is designed to facilitate physiologic measurements of the animal through an integrated or associated sensor mount. The physiologic sensors include those for the measurement of pulse oximetry and other measurements such as breath rate, heart rate, pulse distention and breath distention, temperature to name a few. A tail engaging sensor mount geometry is provided for a particular pulse oximeter into the back plate of the tube. The immobility of the animal is especially important given the fact that pulse oximetry measurements are extremely susceptible to even the smallest motion artifact.

A small animal restraining tube comprises a tube configured to receive a small animal therein; a nosecone within the tube and coupled thereto and configured to abut the animal within the tube to confine the animal on one side of the tube; an endplate coupled to the tube and configured to confine a body portion of the animal on a side opposite the nosecone, whereby the body of the animal is confined within the tube between the nosecone and the endplate, the endplate including an opening there through configured to receive a tail of the animal when the animal is confined within the tube; and a tubular loader mechanism selectively coupled to the tube, wherein the loader mechanism is configured to selectively receive the animal therein and configured to transfer the animal to the retraining tube.
摘要:
A high frequency pressure oscillation device that selective restricts the flow of breathing gas to or from a patient to produce pressure spikes in the patient's airway that facilitate clearing secretions from the patient's airway. The device includes a patient circuit that defines a closed path between a source of breathing gas and the patient's airway. A valve is disposed in the patient circuit such that in an open position the path between the source of breathing gas and the airway of the patient is substantially unobstructed. When the valve is in a closed position, the path between the source of breathing gas and the patient's airway is at least partially obstructed to create the pressure spikes. An actuating system associated with the valve alternatively places the valve in the open position and in the closed position at a predetermined oscillation rate that is independent of patient effort.

A portable electronic device includes a body for housing processing circuitry, the body configured for being carried or worn by a user. A battery is coupled with the body for providing power to the processing circuitry. A flexible heater unit is disposed adjacent to the battery, the flexible heater unit is operable to generate heat when powered to transfer heat to the battery. A photonic power source is configured for being carried or worn by a user and operatively coupled with the flexible heater unit to provide electrical power to the flexible heater unit.
摘要:
A flow sensor is disclosed that measures a flow of fluid passing through a conduit and a flow resistive element for use in such a flow sensor. The flow sensor includes a housing having a main channel defined therethrough. A flow resistive element is disposed in the housing across the main channel. The flow resistive element includes a rigid body member having a first surface and a second surface. A plurality of unobstructed, wedge-shaped, openings are defined in the body member and extend through the rigid body member. In addition, a plurality of spokes extend from a central portion of the body member to its perimeter so that each spoke separates adjacent wedge-shaped openings from one another.
