A capnometer includes an airway adaptor for letting a respiratory gas pass therethrough, a light source for holding the airway adaptor and irradiating with infrared radiations the respiratory gas passing through the airway adaptor, a detecting portion having an infrared radiation detector for detecting the infrared radiations that have passed through the respiratory gas, and a monitor body for measuring the concentration of respiratory carbon dioxide gas by receiving a signal from the detecting portion, wherein an angle is defined between the channel of the airway adaptor and a display surface of the monitor body.
Abstract:
An oxygen mask can include an oxygen supply unit and an attachment unit which is to be attached to a periphery of a nose or a nose and a mouth of a patient. The attachment unit includes an opening which communicates with external air and which is formed at a position to which, when the oxygen mask is attached to the patient, at least one of the nose and the mouth of the patient is opposed.
Abstract:
An artificial ventilation apparatus includes: a connecting portion which is connected to a respiratory system of a patient; an inspiratory circuit which is a flow path for flowing a gas from a ventilator to the connecting portion; an expiratory circuit which is a flow path for guiding a gas exhausted from the connecting portion to an exhaust portion of the ventilator; an expiratory valve which blocks a flow of a gas from the exhaust portion toward the connecting portion; a carbon dioxide concentration sensor which is disposed in a circuit that is provided at a downstream side of the expiratory valve and which detects a carbon dioxide concentration; and an alarm outputting unit which outputs an alarm based on an output of the carbon dioxide concentration sensor.
Abstract:
An adaptor is adapted to be attached on a face of the subject to collect expiration gas of the subject. An airway case is formed with a chamber, and adapted to be coupled with a carbon dioxide sensor so that carbon dioxide in the expiration gas flowing through the chamber is detected by the carbon dioxide sensor. Nasal tubes are adapted to be inserted into nostrils of the subject when the adaptor is attached on the face of the subject. The nasal tubes are adapted to lead nasal expiration gas of the subject to the chamber. A mouth guide is adapted to lead oral expiration gas of the subject to the chamber when the adaptor is attached on the face of the subject. A branch tube is communicating with the nasal tubes and adapted to lead pressure generated by the nasal expiration gas to an external pressure sensor.

Abstract:
A system, flow meter, and method for measuring gas flow information, such as respiratory information. In an exemplary embodiment, the flow meter may include a cylindrical body that allows the respiratory gas to flow through and at least one hot wire disposed within the cylindrical body. Further, the flow meter may include a bridge circuit that includes the at least one hot wire as a resistive element and an extraction circuit that extracts a signal from the bridge circuit indicating the respiratory volume. A first filter and second filter may be disposed at an output side of the extraction circuit, and a detection circuit may be included that detects the respiratory flow rate from the output signal of the first filter and detects sound, such as snoring from the output signal of the second filter.
Abstract:
A probe is adapted to emit light having at least one wavelength as irradiation light with respect to a measured portion on a biological body in order to measure a biological signal. A light emitting element is configured to emit the light having the at least one wavelength. A light guiding member is provided with: a first end face, being light-reflective and having a first part opposing the light emitting element and a second part surrounding the first part; a second end face, being light-reflective and intersecting the first end face; and a third end face, being light-permeable, opposing the first end face and intersecting the second end face. The light guiding member is configured such that at least part of the light emitted from the light emitting element is reflected by at least one of the first end face and the second end face, and emitted from the third end face as the irradiation light. A light receiving element is configured to receive light reflected by the measured portion. A section shape of the first end face in a direction along an optical axis of the light emitting element is such a shape that at least the second part is coincident with a circumference of an ellipse intersecting a minor axis of the ellipse, and the optical axis of the light emitting element is coincident with the minor axis of the ellipse.
Abstract:
Windows 2 which allow infrared light to be transmitted therethrough are opened at opposed positions of side walls of a flow tube 1, respectively. A hexagonal frame 6 is air tightly attached to each of the apertures. Each frame 6 is protruded from the inner face of the flow tube 1. A transparent window on which an anti-fogging layer 5 is formed stretches on the inner face of each of the frame 6, so that waterdrops flowing through the flow tube 1 are caused to flow along both the sides of the frame 6, thereby preventing the waterdrops from flowing over the anti-fogging layer 5.
Abstract:
A capnometer is disclosed with a light sourse for irradiating a respirtory gas, a thermal detector for sensing the transmission of the infrared radiation, a switch device for turning the radiation source on and off in a predetermined period, a memory device for storing output from the thermal deterctor, and a control device for picking up a maximum value of the detection signal from the thermal detector for the present inspiration phase. The maximum value is stored in the memory device and the difference is calculated between a subsequently issued detection signal and the stored maximum value to compensate for drift that has occurred in the thermal detector.
