A system and process for an oxygen flow control system for supplemental oxygen is provided, including a system with an optical flow sensor and 3-way solenoid that operate to detect inhalation and deliver a microburst of oxygen that is electronically controlled based on one or more parameters.

A sleep system can introduce outside stimulus such as simulated heartbeat and/or respiration to induce a response from the sleeper which can cause the sleeper's body to mimic or mate up with the delivered heartbeat and/or respiration sequence. Simulated heartbeat and/or respiration introduced to the person's sleeping environment can guide the person from an awake state to a sleeping state, help the person transition between sleep stages, help the person maintain one or more sleep stages for longer or shorter durations, and gently guide the person from an asleep state to an awake state. The simulated heartbeat and/or respiration can also improve the quality of sleep that the person experiences in a given sleep phase.

Systems and methods for nitric oxide generation are provided. In an embodiment, an NO generation system can include a controller and disposable cartridge that can provide nitric oxide to two different treatments simultaneously. The disposable cartridge has multiple purposes including preparing incoming gases for exposure to the NO generation process, scrubbing exhaust gases for unwanted materials, characterizing the patient inspiratory flow, and removing moisture from sample gases collected. Plasma generation can be done within the cartridge or within the controller. The system has the capability of calibrating NO and NO.sub.2 gas analysis sensors without the use of a calibration gas.

Disclosed are systems and methods for influencing the mood of a person using a synthetic window. The system includes storing one or more excitement scenes and one or more calming scenes, where the excitement scenes when displayed on the display produce an excitatory environment and the calming scenes when displayed on the display produce a calming environment. The system also includes receiving input as to a type of mood of the person, selecting an excitement scene or a calming scene in response to the mood type received, and displaying the selected scene on the display.

A sleep-aiding audio signal updating method and apparatus in the artificial intelligence (AI) field is provided. The method includes: obtaining a first biological signal collected when a first audio signal in a sleep-aiding audio library is played, where the first biological signal is a biological signal of a first user; determining a sleep quality of the first user based on the first biological signal; and updating the sleep-aiding audio library based on the sleep quality of the first user, so that a sleep-aiding audio signal can be updated, to provide a proper sleep-aiding audio signal for a user, and ensure a sleep-aiding effect.

A system and process for the recovery of at least one halogenated hydrocarbon from a gas stream. The recovery includes adsorption by exposing the gas stream to an adsorbent with a lattice structure having pore diameters with an average pore opening of between about 5 and about 50 angstroms. The adsorbent is then regenerated by exposing the adsorbent to a purge gas under conditions which efficiently desorb the at least one adsorbed halogenated hydrocarbon from the adsorbent. The at least one halogenated hydrocarbon (and impurities or reaction products) can be condensed from the purge gas and subjected to fractional distillation to provide a recovered halogenated hydrocarbon.

A cloud platform comprises a receiving unit and a processing unit. The receiving unit is configured to receive at least one user respiration data set sent by at least one respirator device in at least one uploading cycle. The processing unit is configured to acquire a first user respiration data set sent by a user of one respirator device among at least one respirator device in one uploading cycle, statistically analyze the first user respiration data set on the basis of a stable state value set of the user, and send an alarm signal when the statistical analysis result is determined to be that the first user respiration data set meets a data exception standard. The disclosure provides an on-line user respiration data analysis solution in combination with disease diagnosis of an off-line respiration system, so that the worsening of a patient's conditions can be possibly found in time.

In some embodiments, an apparatus for providing negative pressure wound therapy to multiple wounds includes a negative pressure source configured to couple via a plurality of fluid flow paths to a plurality of wound dressings. The plurality of flow paths includes a plurality of calibrated leaks. The apparatus also includes a controller configured to determine a total rate of flow in the plurality of fluid flow paths and compare the total rate of flow to a plurality of thresholds associated with the plurality of calibrated leaks to determine one or more operating conditions, such as a blockage in one or more of the plurality of flow paths. An indication of the operating condition can be provided.

Provided are a blood purification system, etc., to enable more achieve more efficient purification of blood. A blood purification system includes a line through which a liquid containing blood or filtrate flows, a plasma separation device to separate a plasma component from blood flowing through the line, a factor separating device to separate a factor component which is a pathogenic factor from the plasma component, a detector to detect blood information relating to blood flowing through the line, a liquid control mechanism to control flow of liquid in the line based on control parameters, a parameter acquisition module to input the detected blood information into a learning model trained to output predetermined control parameters when predetermined blood information is input, and acquire control parameters output from the learning model, and a control module to control the liquid control mechanism based on the acquired control parameters.

The invention relates to a ventilation monitoring system comprising a ventilation data capturing device connected between a patient and a ventilator device dedicated to the patient, for collecting ventilation data between the patient and ventilator device; an on-site device; a remote device for communicating with the ventilation data capturing device and the on-site device; at least one processor; and at least one memory device coupled to the at least processor configured to: collect ventilation data from the ventilation data capturing device; transmit the collected ventilation data to the remote device/server for analysis; and generate output data comprising the instructions/commands for actioning on the ventilator device, to provide suitable ventilation support to the patient, or generate output data comprising the status of the ventilator device associated with the ventilation data capturing device.
