The disclosed embodiments relate to the design of a preconcentrator system for preconcentrating air samples. This preconcentrator system includes a plurality of preconcentrators that preconcentrate the air samples prior to chemical analysis, and a delivery structure comprising a manifold that selectively routes a sample airflow to the plurality of concentrators so that the plurality of preconcentrators receive a sample airflow concurrently or individually.

A breath analyzer, a system, and a computer program for administering a breath analysis to a donor and recording a breath analysis result. Embodiments of the invention authenticate that the breath analysis was performed correctly, preserves the breath analysis results by communicating with other devices, and presents the breath analysis results by superimposing them on recorded video data. The breath analyzer includes a breath receptor for receiving a breath sample from the donor, an analyzing element for determining a breath analysis result, a communications element for sending information indicative of the breath analysis result to a recording device manager, and a housing for securing the components in a handheld device. The system comprises the breath analyzer, a recording device manager for synchronizing the recordings, and at least one ancillary camera for recording the breath analysis.

A rapid-testing mask is worn by a user, and includes a covering portion, a strap portion and a rapid-testing portion. The covering portion is provided to cover the mouth and the nose of the user. The covering portion includes an inner layer close to the user and an outer layer opposite to the user. The strap portion is connected to the covering portion and is worn on the user. The rapid-testing portion is arranged on the inner layer of the covering portion, and receives a gas exhaled from the mouth or the nose of the user to generate an indication signal according to the gas. The indication signal is a rapid-testing result of whether the user is suffering from diseases of pneumonia, influenza and COVID-19 (Coronavirus disease 2019), to monitor health status of the user in real time.

In an embodiment, an apparatus (100) is described. The apparatus comprises an infrared, IR, generating system (102). The IR generating system comprises a first IR source (104) configured to produce IR radiation for forming a first IR beam (106) in a first spectral band. The IR generating system further comprises a second IR source (108) configured to produce IR radiation for forming a second IR beam (110) in a second spectral band. The apparatus further comprises a beam manipulation system (112) configured to combine a beam path of the first and second IR beams and direct the first and second IR beams along the beam path through a gas sample region (114). The apparatus further comprises an IR detection system (116) configured to detect an intensity of the first and second IR beams after passage through the gas sample region. The IR detection system is configured to produce a signal (118) from which an indication of a concentration of a target gas in the gas sample region can be derived.

A pulmonary neuromuscular metrics device that allows the measurement of pulmonary neuromuscular metrics, that is, breathing power, force, and work (that is, energy expended), in patients with neuromuscular conditions. The device may be used in the medical office or remotely at a patient's house, thereby allowing the patient to be followed medically without the need for more frequent and repeated office visits.

The invention refers to a patch cable for connecting a respiratory module (103) to a breathing adapter (101) being, e.g., part of a capnography system. The patch cable (110) comprises a) a module connector (113), b) an adapter connector (114) comprising a light detector, c) a light guide, and d) an electric cable for directing an electric detection signal generated by the light detector from the adapter connector to the module connector. The adapter connector is configured such that an end of the light guide is positioned to provide the light into a gas cavity of the breathing adapter. The adapter connector is adapted such that the light detector detects light provided by the end of the light guide that has interacted with the gas provided in the gas cavity, when the adapter connector is connected to the breathing adapter. This, allows to improve the accuracy of respiratory gas detection.

A personal respiratory isolation system (PRIS) provides a personal, negative pressure environment for a patient or user that reduces contamination and spread of pathogens exhaled by the patient into the environment. The PRIS includes an enclosure to receive the patient's head (such as a hood and a drape) and a negative pressure source which draws ambient air into the interior of the enclosure and draws air within the enclosure's interior (including the exhalations of the patient, including any contaminants and/or pathogens) out of the enclosure via a fluid port into a container for biohazard processing or disposal. The PRIS may allow positive air pressure therapeutic treatments to be delivered to the patient within the negative pressure environment, and the PRIS may maintain a constant pressure within the interior of the enclosure. The PRIS may include a transparent, hinged face shield for ease of patient observation and/or access.

An airway adaptor includes: a gas passage into which a respiratory gas of a subject is to flow; a respiratory gas introducing portion which is configured to guide the respiratory gas expired from at least one of nostrils and a mouth of the subject, to the gas passage; and an airway case on which a temperature sensor that is configured to detect a temperature change of the respiratory gas flowing into the gas passage is mountable.

The present disclosure presents methods, systems and devices for performing capnography (respiratory CO.sub.2) monitoring using a respiratory CO.sub.2 sensor and a breath tracking mechanism for tracking and/or detecting phases of the breath wherein the measurements of the CO.sub.2 sensor may provide baseline CO.sub.2 values, and modulate/quantify the respiratory CO.sub.2 levels according to the baseline values.

Aspects relate to systems and methods for individualized content media delivery. An exemplary system includes a sensor configured to detect a biofeedback signal as a function of a biofeedback of a user, a display configured to present content to the user, and a computing device configured to control an environmental parameter for an environment surrounding the user as a function of the biofeedback signal, wherein controlling the environmental parameter additionally includes generating an environmental machine-learning model as a function of an environmental machine-learning algorithm, training the environmental machine-learning model as a function of an environmental training set, wherein the environmental training set comprises biofeedback inputs correlated to environmental parameter outputs and generating the environmental parameter as a function of the biofeedback signal and the environmental machine-learning model.
