20170361058 · 2017-12-21 ·

The present technology relates generally to cough-assist devices with humidified cough assistance. In one example, a system includes a cough-assist device having a first phase configured to provide insufflating gas to a patient circuit and a second phase configured to draw exsufflating gas from the patient circuit. A humidifier is disposed between the cough-assist device and a distal end of the patient circuit, the humidifier including a chamber configured to contain heated water and fluidically coupled to the cough-assist device and the patient circuit. The system further includes a bypass configured to (a) direct insufflating gas from the cough-assist device through a first route to the patient circuit such that the insufflating gas is humidified in the chamber, and (b) route exsufflating gas from the patient circuit through a second route to the cough-assist device such that the exsufflating gas bypasses the chamber.

SYSTEMS AND METHODS FOR PREDICTING MASK LEAKS

A method of predicting an unintentional leak in a respiratory system during a sleep session includes causing, during the sleep session, pressurized air to be delivered from a respiratory device to a user via a conduit coupled to a user interface. The method also includes receiving historical first data associated with pressurized air delivered from the respiratory device during one or more prior sleep sessions; receiving current first data associated with the pressurized air being delivered from the respiratory device during the sleep session; receiving historical second data associated with the user during one or more prior sleep sessions; and receiving, via one or more second sensors, current second data associated with the user during the current sleep session. The method determines, a likelihood that an unintentional leak in the respiratory system will occur within a predetermined amount of time.

DEVICE FOR ARTIFICIAL RESPIRATION

The disclosed device serves for artificial respiration and has a blower connected to a control. The blower is held by a supporting part, which assumes the task of decoupling and other functions. The blower and the supporting part are arranged in a blower box. Both the control and the blower box are arranged in a housing. The control is connected to at least one indicating device and also to at least one operating element.

CONTROLLING A HIGH FLOW NASAL THERAPY DEVICE

Provided are concepts for controlling a high flow nasal therapy (HFNT) device used by a subject. In particular, physiological and movement parameter values of the subject are leveraged in order to generate a control signal for the HFNT device. These parameters may indicate an activity level of the subject, as well as the condition of the subject, providing information useful for setting appropriate operating conditions of the HFNT device. Thus, a means for automatically controlling a HFNT device based on needs of the subject may be provided, improving subject comfort during therapy, and ease of use of the HFT device.

Methods and systems for delivering gas to a patient

A system is provided for delivering gas to a patient during a medical procedure. The system comprises a heater arranged to heat at least one of the gas and a humidification liquid. The system comprises a controller arranged to control the system according to a first mode during delivery of a first flow rate of gas and a second mode during delivery of a second flow rate of gas. The controller monitors an electrical characteristic of the heater to select the mode of operation and/or to determine an operating state of the system.
