摘要： A liquid separator for a respiratory gas sample analyzer includes a closed container having a liquid trap filter chamber integral with the container. The liquid trap filter chamber includes an inlet compartment and an outlet compartment. The inlet compartment is interposed between a sample inlet port and a sample outlet port and includes a gas permeable, liquid impermeable filter element for separating liquid from a gas sample, the liquid separated from the gas sample passing to a collection chamber. The outlet compartment includes a further gas permeable, liquid impermeable trap filter element which is interposed between the collection chamber and a low pressure port, for preventing the flow of liquid' through the output compartment to the low pressure port.

摘要： An apparatus and method for noninvasively sensing parameters associated with the health of a fetus, the health of the placenta and the mother. The device includes a probe (10) for inserting the sensor within the uterus of the mother, and the probe (10) includes a flexible distal end portion (12) having an independent inclination to assume an outward spiral curvature relative to the fetus. The probe (10) has a transversely concave shaped channel to receive sensor cabling and control wires. The sensors (32, 33, 34) can measure heart rate, oxygen saturation, temperature, chemical parameters, electroencephalogram activity and other useful parameters. The probe (10) may also be used to infuse or remove fluid in the uterus.

摘要： This invention is an oximeter for non-invasive measure of the oxygen saturation in blood with increased speed and accuracy. The device includes a sensor unit (20) which can be attached to a patient, and an oximeter (10) which determines the oxygen saturation in the blood based on signals received from the sensor (20). In the present invention, the detected signal is immediately converted to a digital value (30).

摘要： An inline water trap including a filter component and a panel connector configured to interface with a patient gas monitor. In one embodiment the inline water trap indicates to the patient gas monitor that it is in place and that the patient gas monitor may begin intaking and analyzing the filtered patient sample. The inline water trap receives a patient sample and filters water and contaminants from the sample before allowing the remaining gas portion of the sample to pass through to the patient gas monitor, thereby protecting the patient gas monitor from damage. One embodiment of the inline water trap additionally contains an RFID tag to indicate to the patient gas monitor that the correct type of inline water trap is engaged.

摘要： This invention is an oximeter for non-invasive measuring the oxygen saturation in blood with increased speed and accuracy. The oximeter includes a number of features which increase the functionality of the device including a dynamic range control (62) for monitoring a range of inputs from low level signals encountered in fetal, and other applications to typical or high level signals; light emitting devices (70, 80, 100) of different wavelengths for filtering noise, and providing additional medial monitoring functions; and an improved method for calculating the oxygenation levels without the need to take peak and valley measurements. The device includes a sensor unit (20) which can be attached to a patient, and an oximeter (10) which determines the oxygen saturation in the blood based on signals received from the sensor. The sensor can include light emitting devices in three or more wavelengths to provide additional functions. The detected signal is immediately converted to a digital value.
