Принадлежит: CHINA MEDICAL UNIVERSITY

A liquid trap cup is provided. The liquid trap cup comprises a hollow cup tube with a upper portion and a lower portion, a piston element with a top portion and a tail portion and a liquid discharge structure, in which the piston element is arranged airtight in the lower portion and is movable between a start point and an end point of the lower portion so as to control the opening and the closing of the liquid discharge structure. A liquid trap assembly using the liquid trap cup is provided. The liquid trap assembly comprises said liquid trap cup and a multi-necked adapter tube with an expanded-plate structure, in which expanded-plate structure can be tightly sealed with the liquid trap. When applying the liquid trap assembly to a breathing system, it can simply drain the liquid collected in the liquid trap cup without disassembling the liquid trap assembly so as to prevent the infection problems of patients and reduce the burden of the medical staff.

Принадлежит: LUNG ASSIST Inc

An MIE apparatus has a blower, a direction valve, an oscillator, and a mask hose connector. The blower is connected to the direction valve, which is connected to the oscillator, which is connected to the hose connector. During insufflation, a direction valve connects exhaust of a blower to an oscillator, causing positive pressure at the hose connector. During exsufflation, the direction valve connects the blower intake to the oscillator, causing negative pressure at the hose connector. The oscillator is a butterfly valve with a 360° rotating disc. During insufflation, the disc is fixed to steadily modulate the airflow. During exsufflation, the oscillator is inactive or in flutter mode. When inactive, the disc is fixed to allow maximum air flow. In flutter mode, the disc continuously rotates so that the air flow rapidly alternates between maximum and minimum.

A modularized respiratory treatment apparatus provides various respiratory pressure treatments. The apparatus may be formed by discrete connectable modules such as a flow generator module, alarm module and/or humidifier module. Each module may include its own external casing or housing to independently retain or enclose the respective components that serve the function of the module. Different modules may be adapted with different components and functionalities and may be readily coupled using standardized gas and electrical connection configurations that have flow and communication paths that extend through the modules. When coupled, operation of the respiratory treatment apparatus may be controlled by detection of different modules, such as the alarm module that generates visual and/or audible alarms based on detected conditions, so as to selectively enable or disable different respiratory treatments. The discrete modules of the medical treatment apparatus may include tamper resistant locking mechanisms to impede unauthorized separation of some modules.

Systems and methods are described for application of a transitory corrective modification to a hot-wire anemometer flow voltage and/or calculated flow rate to compensate for transient thermal response of the anemometer during a change in mixture of a mixed gas being measured. According to one embodiment a method of applying the transitory corrective modification is provided. An output signal of an exhalation flow sensor of a medical ventilator is received. The flow sensor includes a hot-wire anemometer. The output signal is indicative of a rate of flow of expired gas by a patient. Transient thermal response of the hot-wire anemometer is compensated for by applying a corrective modification to the output signal or a value based thereon. The corrective modification is based at least in part on a fraction of inspired oxygen (FiO2) being supplied by the medical ventilator to the patient. 118.-. (canceled)19. A method comprising:one or more flow sensor processing modules of a medical ventilator receiving an output signal of an exhalation flow sensor including a hot-wire anemometer, the output signal indicative of a rate of flow of expired gas by a patient;the one or more flow sensor processing modules compensating for transient thermal response of the hot-wire anemometer resulting from a change in concentration of gas types included within the expired gas by applying a corrective modification to the output signal or a value based thereon that is based at least in part on a mixed gas being supplied to the patient by the medical ventilator; andwherein the one or more flow sensor processing modules are implemented in one or more microprocessors and one or more computer-readable media, the one or more computer-readable media having instructions tangibly embodied therein that are executable by the one or more microprocessors.20.

According to various embodiments, methods and systems for determining pressure in the lungs may employ intracuff pressure measurements. The intracuff pressure measurements may calibrated or adjusted based on a set of calibration coefficients or a set of calibration curves, which may reflect patient parameters and cuff/tube geometry factors. The resulting calibration may be used to determine a more accurate estimate of lung pressure, which in turn may be used to control a ventilator and provide breathing assistance to a patient. Also provided are tracheal tubes with couplers or other memory devices for storing calibration information. Such tubes may allow calibration at the level of an individual tracheal tube to account for changes in tube geometry and individual patient factors.
