Various characteristics of a gas flow can be sensed at the end of a respiratory conduit near the patient interface using a sensing module. The sensing module can be removable from the patient end of the respiratory conduit for ease of use and ease of cleaning. The sensor module can transmit sensor data over the same wires used to heat the respiratory conduit.

A negative pressure respiratory treatment hood for human medical patients. A rigid hood, preferably of unitary fabrication from a clear material, is positioned over the patient's head. The patient's body extends out of an opening in a front wall of the hood. A hinged door may be attached to the front wall of the hood, and is closed and partially closes the opening, and a shroud is sealing connected to the hood and is draped over the patient so as to form a pressure seal. A negative pressure source is connected to the hood and forms a negative pressure environment around the patient's head. Access openings have a resilient material across them, with small openings in the resilient material, to permit access to the patient by medical personnel and/or medical equipment.

The present invention relates to a device (100) and a system for positive pressure ventilation (PPV) and continuous positive airway pressure (CPAP) treatment comprising a fresh gas flow inlet (2), arranged to receive a fresh gas flow from a fresh gas flow tube (22) connectable thereto; a patient interface end (3), arranged to be connected with a patient interface; an outlet (4) having an open end (5); a variable flow CPAP generator (6) comprising first, second and third connection portions (10, 11, 12), wherein the first connection portion is connected with the fresh gas flow inlet, the second connection portion is connected with the patient interface end, and the third connection portion is connected with the outlet, wherein the generated CPAP level is adjusted by varying the fresh gas flow to the variable flow CPAP generator. The device further comprises an internal leakage channel (9) arranged to extend between the fresh gas flow inlet and at least one of the patient interface end and the outlet, such to create an internal fresh gas leakage flow there between, bypassing the first connection portion of the variable flow CPAP generator, which is added to the fresh gas flow provided by the variable flow CPAP generator in the PPV mode. A simplified device and system is provided, respectively, which is easy to use and allows for a rapid switch between PPV and CPAP treatment without change of equipment.

A method and apparatus deliver a variable flow of oxygen to a patient. The apparatus may include a flow control valve, a pressure sensor to detect a patient's breathing pressure and ambient pressure, an oxygen flow analyzer to measure oxygen flow to the patient, and a processor to analyze the breathing pressure values, ambient pressure value, and oxygen flow rate values and to determine when a patient is inhaling. When the processor determines the patient is inhaling, the processor calculates an optimal oxygen flow rate to deliver to a patient, which may depend on a pre-selected flow rate and an oxygen backlog, and the processor sends a signal to the flow control valve to deliver the optimal oxygen flow rate to the patient.

The present invention relates to a plurality of ventilation devices, to ventilation devices having visualization apparatuses, and to methods for operating the ventilation devices. The intent is to minimize the energy input into the at least one airway of a patient as a result of the ventilation.

Module for housing electronic and electromechanical medical equipment including a portable digital camera and processing circuitry with machine vision and machine learning software for automatically documenting healthcare events and healthcare equipment operations in the electronic health record.

A device, system and method related to a pneumatic system for fluid analysis. The device, system and method comprise a connection interface for a fluid analyzer unit, a connection interface for a pump unit, a flow sensor and a pressure sensor. The device, system and method further comprises a control unit for calculating a pump stroke force or amplitude, and/or pump frequency based on measurements from the flow sensor and the pressure sensor for obtaining a constant flow through the pneumatic system.

A measurement device and a method for monitoring a condition of a patient. The measurement device includes: a gas-guide apparatus, connected between an medical gas provider and a patient and configured to deliver medical gas from the medical gas provider to the patient; and at least one sensing apparatus, placed on an outer surface of the gas-guide apparatus and configured to detect real-time measurement data of the medical gas passing through the gas-guide apparatus. In this way, the at least one sensing apparatus is placed on the outer surface of the gas-guide apparatus, since the measurement data is a relative value which indicates a change of internal environment of the gas-guide apparatus, this can also avoid a problem of contamination compared with setting a sensor inside a respiratory device, thus improving the security of the measurement.
