  • Publication number: 20200113621
    Abstract: An electrosurgical forceps includes first and second shaft members and first and second jaw members extending distally from the respective first and second shaft members. A pivot couples the first and second shaft members with one another such that the first and second shaft members are movable relative to one another between a spaced-apart position and an approximated position to move the first and second jaw members relative to one another between an open position and a closed position. The jaw members are configured to facilitate tissue treatment, tissue division, and blunt tissue dissection.

  • Patent number: 10567861
    Abstract: A housing has a bud portion abutting an elongated stem portion. The bud portion is to fit within an ear. The bud portion has a primary sound outlet at its far end that is to be inserted into an outer ear canal, and abuts the stem portion at its near end. A speaker driver is inside the bud portion. Electronic circuitry inside the housing includes a wireless communications interface to receive audio content over-the-air and in response provides an audio signal to the speaker driver. A rechargeable battery as a power source for the electronic circuitry is located inside a cavity of the stem portion. Other embodiments are also described and claimed.

  • Patent number: 7980246
    Abstract: An airway adapter suitable for use with patients having low tidal volumes, e.g., neonates, which minimizes deadspace in the airway and promotes smooth flow of gases through the adapter. The adapter includes a first portion adapted to couple to a tubular adapter, such as an endotracheal tube adapter, and a second portion adapted to couple to a ventilation tube. A longitudinally compressible member is coupled to the first portion to minimize deadspace in the adapter. A portion of the compressible member resiliently contacts and seals against a tubular adapter upon assembly of the airway adapter therewith.

  • Patent number: 7775207
    Abstract: An apparatus and method for affording a re-breathing capability to a breathing circuit. The apparatus includes a valve that permits air flow through or re-breathing in the breathing circuit. A CO2 sensor and an air flow sensor detects CO2 a rate of air flow in the breathing circuit, respectively. A processor computes a parameter based on the CO2 waveform feature and a volumetric CO2 waveform feature based on signals from the air flow sensor and/or the CO2 sensor. An alarm is triggered when the parameter deviates from a selected magnitude. In a further embodiment, at least one parameter associated with an energy source for actuating the valve is monitored. Deviation of the value from at least one selected value of the at least one parameter is corrected.

  • Patent number: 7748280
    Abstract: The invention provides a sidestream gas sampling apparatus having a gas sampling circuit and a set of reusable elements. The gas sampling circuit carries the gas sample from a main flow of gas, through a sample analysis area, and vents the gas sample to an analyzed gas destination. The reusable components provide motive forces to remove the gas sample through the gas sampling circuit and provide analysis components for the gas sampling apparatus while not making contact with the gas sample. As such, the reusable components do not become contaminated by the gas sample and do not have to be cleaned or sterilized between applications.

  • Publication number: 20100036272
    Abstract: A system (300) for measuring a metabolic parameter. The system includes an integrated airway adapter (20, 100, 200) capable of monitoring any combination of respiratory flow, O2 concentration, and concentrations of one or more of CO2, N2O, and an anesthetic agent in real time, breath by breath. Respiratory flow may be monitored with differential pressure flow meters under diverse inlet conditions through improved sensor configurations which minimize phase lag and dead space within the airway. Molecular oxygen concentration may be monitored by way of luminescence quenching techniques. Infrared absorption techniques may be used to monitor one or more of CO2, N2O, and anesthetic agents.

  • Patent number: 7659504
    Abstract: An optical gas sensor includes an optical element that is substantially transparent to both monitoring radiation and warming radiation. Such an optical element facilitates the removal of warming radiation from the optical gas sensor, thereby preventing an increase in the internal temperature of the sensor during use. Additionally, the warming radiation that is emitted from the optical gas sensor may be used to warm one or more windows of a sampling component that is configured for use with the sensor.

  • Patent number: 7549316
    Abstract: Sidestream gas sampling assembly that does not substantially degrade the waveform of expired gases. The gas sampling assembly includes a sample cell portion integrated with a filter portion for separating undesired liquid condensate from respiratory gases to be monitored. The gas sampling assembly is configured to receive expired gases through a gas sampling line, filter undesired liquid condensate from the expired gases through hydrophobic fiber elements and communicate the filtered gases to a sample chamber which is in close proximity to the filter where measurements may be taken thereof e.g., optical or infrared sensing mechanisms. The gases that are substantially free of liquid condensate are then exhausted from the sample chamber.

  • Patent number: 7294839
    Abstract: A sample cell, which is a component of a gas monitoring system, includes a sample cell body and a sample cell core installed therewith. The sample cell is coupled to a sampling tube that communicates with an airway of a patient. Gas from the sampling tube passes through the sample cell such that the flow profile remains substantially undisturbed. Within the sample cell, at least one optical aperture permits radiation to be emitted, pass through the gas in the sample cell core, and detected. In this manner, measurements of the partial pressure or concentration of a gas of interest are determined.

  • Patent number: 7137390
    Abstract: A filter assembly for use in sidestream gas sampling assembly. The filter assembly of the present invention includes a hydrophilic liner lining the inner perimeter of a housing for wicking moisture from the gases to be monitored prior to the gases reaching a sensing mechanism. The filter further includes a hydrophobic member positioned downstream of the hydrophilic liner. The hydrophobic disk acts as a second line of defense against moisture reaching the sensing mechanism. In one embodiment, the filter further include an absorbent layer positioned between the cylindrical housing and the hydrophilic layer to aid in wicking moisture from the gas stream. In a further embodiment, the hydrophobic disk is eliminated and the hydrophilic member is situated such that gas entering the filter assembly must pass through at least a portion the hydrophilic member.
