A thermal flow sensor integrated circuit for sensing flow in a channel based on temperature measurements, the integrated circuit having a temperature sensing element ( 30 ) on a front side of the integrated circuit arranged to face the channel, and a bond pad ( 60, 200 ) coupled electrically to the temperature sensing element, for making electrical contact off the integrated circuit, the bond pad being arranged to face away from the channel. By having the bond pad facing away from the channel, the space needed for the bond pad and any connections to it need not extend beyond the temperature sensing element and get in the way of the channel. Hence the temperature sensing element can be located closer to the channel or in the channel to enable measurements with better response time and sensitivity.

Принадлежит: RESPINOVA Ltd

The invention is a device for the introduction of a fluid into a human's airway. The air so introduced has a carefully modulated envelope of pressure vs. time, this envelope generally consisting of sequences of pressurized air packets of controlled frequency and pressures. The device produces these packets by means of pressurized air occluded by a shutter action which “chops” and interrupts the fluid stream. The vibrations induced by the device within human organs have been shown to have beneficial effects on various bodily systems, such as increase in heart rate variability, increase in absorbed oxygen, decrease in absorbed CO2, and the like.

Process for the automatic control of a respirator

Номер: US20120152249A1
Автор: Frank Sattler, Hans-Ullrich Hansmann, Marcus Eger, Tobias GLAW
Принадлежит: Draëger Medical GmbH

A process for the automatic control of a respirator with a changeover between phases of respiration (inspiration and expiration), by a control unit checking a breathing activity signal for a threshold criterion. If the threshold criterion is met, a changeover is made and the control unit controls the fan of the respirator such that a pneumatic respiration variable (airway pressure, flow) is brought from an actual value to a preset target value for the new phase of respiration. The control unit further divides the change in the respiration variable, from the actual value to the target value, into a plurality of partial steps and checks the current breathing activity signal for the threshold criterion after each partial step. If this threshold criterion is no longer met, the state of operation of the respirator returns to the state before the last changeover, and otherwise, continues with the next partial step.

Intermittent dosing of nitric oxide gas

Номер: US20120199123A1
Автор: Alex Stenzler, Bevin B. McMullin, Chris Miller
Принадлежит: Pulmonox Technologies Corp, Sensormedics Corp

A method and corresponding device are described for combating microbes and infections by delivering intermittent high doses of nitric oxide to a mammal for a period of time and which cycles between high and low concentration of nitric oxide gas. The high concentration of nitric oxide is preferably delivered intermittently for brief periods of time that are interspersed with periods of time with either no nitric oxide delivery or lower concentrations of nitric oxide. The method is advantageous because at higher concentration, nitric oxide gas overwhelms the defense mechanism of pathogens that use the mammalian body to replenish their thiol defense system. A lower dose or concentration of nitric oxide gas delivered in between the bursts of high concentration nitric oxide maintains nitrosative stress pressure on the pathogens and also reduces the risk of toxicity of nitric oxide gas.

A microfluidic device and sensing method that utilize a resonating tube configured to have sufficient sensitivity to be capable of sensing the volume of a gas present as bubbles in a liquid or the flow rate and/or density of a gas or gas mixture flowing through the tube. The tube has a freestanding tube portion supported above a surface of a substrate so as to be capable of vibrating in a plane normal to the surface of the substrate. As a gas-containing fluid flows through an internal passage of the tube, a drive signal vibrates the freestanding tube portion at a resonant frequency thereof. Coriolis-induced deflections of the freestanding tube portion are sensed relative to the substrate to produce an output corresponding to the sensed deflections, and the drive signal and/or the output are assessed to determine the volume, density and/or flow rate of the gas of the gas-containing fluid.

An apparatus is disclosed as part of a system for tracking and confirming delivery of a medicinal dose to a user. The apparatus includes a detector. The detector is secured to and communicatively coupled to the user and is capable of detecting a current flow through the user's body. The current flow is produced when the user makes contact with the apparatus. The apparatus includes at least two contact areas connected to a power source where a circuit and, hence, a current path is completed through the user's body as the user makes contact with the apparatus. The current flow is detected by the detector, which is coupled to the user. Also disclosed is an apparatus for tracking and confirming delivery of a medicinal dose to a user where the apparatus includes an acoustic detector. Upon loading the dose into a chamber an acoustic vibration is generated. The vibration is detected and correlated with a current flow that is produced when the user makes contact with the apparatus. The combined event of vibration detection and current flow detection confirms that the dose is loaded and the user is in contact with the apparatus and ready to receive the dose.

Compensation for unmeasurable inspiratory flow in a critical care ventilator

Номер: US20140014093A1
Автор: Jessica B. Payne, Matthew Michael Stephenson, Paul Hunsicker
Принадлежит: General Electric Co

A system and method for operating a ventilator to compensate for external gas flow reaching a patient from an external device, such as a nebulizer. A control unit of the ventilator monitors the gas flow rate from the ventilator and compares the gas flow rate from the ventilator to an expired gas flow rate from the patient. The difference between the inspired flow rate and the expired flow rate is due to the external device. The control unit modifies the operation of the ventilator to compensate for the external gas flow rate such that the flow of gas reaching the patient is maintained at a desired level.

This disclosure describes systems and methods for monitoring and evaluating ventilatory data to provide useful notifications and/or recommendations. Indeed, many clinicians may not easily identify or recognize data patterns and correlations indicative of certain patient conditions or the effectiveness of ventilatory treatment. Further, clinicians may not readily determine appropriate adjustments that may address certain patient conditions or the effectiveness of ventilatory treatment. Specifically, clinicians may not readily detect or recognize the occurrence of fluctuations in compliance during various types of ventilation. According to embodiments, a ventilator may be configured to monitor and evaluate diverse ventilatory parameters to detect an occurrence of and potential causes for fluctuations in compliance and may subsequently issue suitable notifications and/or recommendations. The suitable notifications and/or recommendations may further be provided in a hierarchical format such that the clinician may selectively access information regarding the fluctuation in compliance and/or potential causes for the fluctuation in compliance.
