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 can include 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.

Oxygen mask

An airway adaptor includes: an airway case; and an expired gas guiding portion which is connected to the airway case to introduce a respiratory gas to the airway case. The airway case includes: a first respiratory gas flow path in which the respiratory gas flows in a first direction; and a second respiratory gas flow path in which the respiratory gas flows in a second direction opposite to the first direction.

Airway adaptor

A flow analyzer includes a flash lamp configured to irradiate a flow cell having a flow path with flash light, the flow path having a predetermined width, an imaging section configured to take images of the flow cell that is irradiated by the flash lamp such that the predetermined width is included in an imaging range, an evaluator configured to detect edges indicating respective sides of the flow cell from an image of a fluid that is taken by the imaging section and to evaluate the fluid passing through the flow cell based on a relationship between a width between the detected edges and the predetermined width, and an output section configured to output a result of the evaluation by the evaluator.

Flow analyzer, flow cytometer and flow analyzing method

The present invention provides a device for displaying respiratory conditions of a subject on a monitor having a first parameter acquisition unit () for acquiring a first respiration parameter representing a respiratory condition of the subject; a second parameter acquisition unit () for acquiring a second respiration parameter representing a respiratory condition of the subject, said second respiration parameter differing from said first respiration parameter; and a display controlling unit () for displaying, on the monitor, a chart representing a relationship between the first respiration parameter acquired by said first parameter acquisition unit and the second respiration parameter acquired by said second parameter acquisition unit; wherein the chart represents the relationship between the first respiration parameter and the second respiration parameter in each respiration cycle, and a plurality of charts for preceding respiration cycles and charts for subsequent respiration cycles are displayed so as to adjoin one another successively in a prescribed direction.

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.

A method of measuring a pH of a solution includes: emitting light beams of two wavelengths from one side of a measuring region of a solution into which an indicator is mixed, while pulsating the solution in the measuring region; receiving at least one of transmitted light beams and reflected light beams of the emitted light beams on the other side of the measuring region, while pulsating the solution in the measuring region; obtaining absorbances of the two wavelengths based on the received at least one of the transmitted light beams and the reflected light beams; obtaining an absorbance ratio from the obtained absorbances; and calculating a pH value of the solution based on the obtained absorbance ratio and an absorbance ratio/pH value correspondence database which is previously stored.

Method and apparatus for measuring PH of solution

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.

Artificial ventilation apparatus

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.

A sensor main unitis axially split into three sub-segments. A light-emitting elementis attached to one end portion, and a light-receiving elementis attached to the other end portion. A respiratory flow pathis formed so as to penetrate through the center portion. The sensor main unitis attached to a position on the face below the nostrils, and respiratory gas from the nostrils is guided into the respiratory flow pathand is caused to cross over the optical axis connected the light-emitting elementand the light-receiving element, thereby measuring a carbon dioxide gas in the respiratory gas.

A bite block includes: a first wall defining a hole into which a conduit pipe is to be inserted; a second wall surrounding the first wall to define a flow path with the first wall; and a sample port communicating with the flow path.

Bite block

A nasal mask is adapted to attached on a face of a subject so as to cover a nose of the subject. A shell has a contact edge adapted to be brought into close contact with the face of the subject, thereby forming a sealed space therein. An attachment portion is disposed in the shell and has an inner space. The attachment portion is configured to detachably engage with a sensor disposed outside the shell and operable to measure concentration of carbon dioxide gas expired from the nostrils. A guide member is disposed inside the shell and forming a passage adapted to introduce expired gas from the nostrils into the inner space. The shell is formed with an inlet adapted to introduce external gas into the sealed space. The expired gas is guarded by the guide member from the external gas introduced through the inlet. The attachment portion is formed with an outlet adapted to discharge the expired gas from the inner space to the sealed space.
