A system for determining the gender and/or fertility status of avian eggs including a sampling apparatus and an electromagnetic radiation transmitter and detector. In certain embodiments, the transmitter operates in the terahertz range. The sampling apparatus can be coupled to an avian egg. The sampling apparatus includes a vacuum source, a gas collection device, and a membrane that can be positioned in the passageway coupling the vacuum source to the gas collection device. The membrane is capable of capturing volatile organic compounds. The sampling apparatus applies a vacuum from the vacuum source to the gas proximate to the avian egg and directs the gas captured from the vicinity of the egg toward the membrane. Subsequently, the membrane is positioned within the electromagnetic radiation emitted by the transmitter, generating a spectrum which can be analyzed to determine whether the egg is fertile or infertile, and if fertile, whether the egg is male or female. In an embodiment, the captured volatile organic compounds are transferred to a sample chamber where the captured gas is analyzed.

An in-line tester (100) comprising: an inlet (16), connectable, in use, to an aspirator tube (18); an outlet (20) connectable, in use, to a vacuum source (22); and a chamber (14) interposed between the inlet (16) and the outlet (20), the chamber (14) comprising: a first tester (108) arranged such that fluids drawn into the chamber (14) by the vacuum source (22) come into contact therewith; a second tester (122) arranged such that fluids drawn into the chamber (14) by the vacuum source (22) pass through it; and a reservoir (114) interposed between the first tester (108) and the second tester (122); wherein the first tester (108) comprises a first colorimetric substance adapted to exhibit a colour change in the presence of a target substance, and wherein the second tester (122) comprises colorimetric capnometer, which exhibits a colour change in the presence of carbon dioxide, the in-line tester (100) further comprising a liquid-stop device (52) which, when dry, permits the passage of gas from the inlet (16) to the outlet (20), but when wetted by a liquid, inhibits or prevents the passage of fluids from the inlet (16) to the outlet (20).

The various embodiments herein provide a device for analyzing a rectum gas discharge. The device comprises a central bag, a peripheral bag, and an electronic unit. The central bag comprises a gas inlet and a gas outlet on directionally opposite ends of a central bag surface. The peripheral bag is housed in a container and radially encapsulates the central bag. The electronic unit comprises a pressure sensor and a connector for further connecting a monitoring unit. The pressure sensor is attached over a surface of the peripheral bag. The central bag is attached to an anal canal of a patient and expands on ingestion of discharged rectal gas from the anal canal. The peripheral bag expands with the central bag resulting in activation of the pressure sensor to measure a gas collected in the central bag.

A system is provided for collecting and logging the frequency of flatulence of a person in a selected time period as well as the duration of each occurrence of flatulence. The log entries provide determination of the body cells signaling of the person indicative of the person's health condition whereby underlying diseases may be detected and treated in their early stage.

Identifying gut microbiota in a specific site of the gut through production of a measurable response following introduction of a challenge agent to the specific site of the gut is disclosed. A system embodiment includes, but is not limited to, a composition including the challenge agent; and an emissions analysis device including a body structure defining an orifice configured to receive a biofluid; a sensor operably coupled to the orifice and configured to detect at least one analyte from the biofluid and generate one or more sense signals, the one or more sense signals associated with the measurable response; circuitry operably coupled to the sensor and configured to receive the one or more sense signals associated with the measurable response; and a reporter operably coupled to the circuitry and configured to generate one or more communication signals associated with at least one targeted microbe.

The health monitoring toilet system includes an extendable, retractable, and rotatable wand with sensors on the head section. The sensors may include a variety of cameras and gas sensors for inspecting a user's urogenital, perineal, and anal region for health assessment. The wand may comprise a bidet wand. The bidet wand may also dispense cleansing and therapeutic substances. The toilet system may include a controller which may store the sensor readings as well as protocols for moving the wand to acquire optimal sensor readings. The controller may be accessible by a healthcare provider for diagnostic and treatment purposes. The toilet system may identify each user to store sensor reading acquired for different users in the controller.

Abnormal S-nitrosothiol metabolism is involved in many different diseases, ranging from asthma to septic shock. A critical limitation of current methods for quantifying S-nitrosothiols present in vivo is that samples need to removed be from the body for analysis. The technology of the present disclosure determining S-nitrosothiol levels in situ using ultraviolet light to cleave the SN bond, releasing the nitric oxide, collecting the nitric oxide, and measuring the nitric oxide.

Transdermally emitted gasses are detected by applying a dermal sampling strip to the skin of a biological subject, capturing the gasses in a vapor space in the dermal sampling strip, and analyzing for at least one such gas captured in the vapor space of the dermal sampling strip. Analysis is preferably performed using an electrocatalytic cell, which can be mounted on the dermal sampling strip and form a wall of the vapor space.

A method is disclosed comprising providing a biological sample on a swab, directing a spray of charged droplets onto a surface of the swab in order to generate a plurality of analyte ions, and analysing the analyte ions.

A vapor sensor comprises a housing with an inlet opening in fluid communication a sensor element within the housing. Standoff member(s) are positioned to maintain a gap between the inlet opening and a skin site. An operating circuit is in electrical communication with the sensor element and communicatively coupled to and output member. In use, the output member generates a sensory output indicative to an operator regarding concentration of alcoholic vapor in the ambient atmosphere proximate the skin site upon receiving communication from the operating circuit.
