Aspects of the technology include methods and systems for performing remote adjustments to a ventilator with a remote device. A remote device may include an interactive display including a remote position indicator. The remote position indicator may be associated or correlated with a local ventilator position indicator. A selection and/or adjustment at the remote device (or an activation at the remote device) at the interactive display may result in a selection, adjustment, or activation at the ventilator. Information may be transmitted to the ventilator from the remote device to remotely adjust the ventilator. Additionally or alternatively, the remote device may additionally display a view of, or replicate, some or all portions of the ventilator display.

A portable medical ventilator using pulse flow from an oxygen concentrator to gain higher oxygen concentration includes a positive pressure source to deliver pressurized air to the patient and a negative pressure source to trigger the oxygen concentrator. A patient circuit attached to a patient interface mask connects the ventilator to the patient. The ventilator includes a controller module that is configured to generate a signal to the negative pressure device to trigger the concentrator to initiate one or more pulses of oxygen from the oxygen concentrator. The oxygen pulses are delivered to the patient interface directly through multi-tube or a multi lumen patient circuit. The oxygen does not mix with air in the ventilator or in the patient circuit and bypasses the leaks in the patient circuit and/or patient interface.

A cushion for a respiratory mask is provided. The cushion includes a face contacting portion, a non-face contacting portion and an intermediate region. The face contacting portion is formed from an open cell foam material and includes an opening to provide, in use, a source of breathing gas to a user's airways. The non-face contacting portion is formed from an elastomeric material. The intermediate region is formed between the face contacting portion and the non-face contacting portion. Open cells of the open cell foam material in the intermediate region are filled with the elastomeric material.

A patient interface includes a shell with a central opening configured to receive the pressurized flow of air, a foam cushion, and an elastomeric support portion that is attached to the shell, supports the foam cushion, and forms at least part of a chamber together with the shell and the foam cushion. The elastomeric support portion includes a side wall that forms a continuous perimeter around the chamber and a resiliently flexible lip that supports the foam cushion and extends from the side wall toward an interior of the chamber. The resiliently flexible lip has an outer perimeter that is anchored to the side wall and an unsupported inner perimeter. The foam cushion overhangs the inner perimeter of the resiliently flexible lip, and the shell is more rigid than the elastomeric support portion. In addition, the foam cushion is configured to directly contact and engage a portion of the patient's skin in use.

The present invention pertains to a device (1) for ventilating a patient, including an invasive mechanical ventilator (2) for periodically providing a breathing gas to an invasive patient interface (20), wherein a gas injector (4) for injecting nitric oxide supplied by a source of nitric oxide (3) into the breathing gas supplied by the invasive mechanical ventilator (2) is provided.

A ventilator (100) ventilates a patient (102) by a high-flow oxygen therapy via a tube system (104). The ventilator has at least one sensor element (110), at least one actuatable inhalation valve or exhalation valve (120) and a control unit (130). The sensor element is arranged and configured to determine and to output a measured variable (112) within the tube system. The measured variable indicates a gas flow within the tube system. The actuatable inhalation valve or exhalation valve is arranged and configured to make possible a flow of a breathing gas from a ventilation circuit (107) of the ventilator. The control unit regulates a ventilation pressure provided by the ventilator via the at least one sensor element and the at least one inhalation valve or exhalation valve such that a predefined maximum pressure is not exceeded in a predefined area (140) of the tube system.

A ventilation gas cooling apparatus is configured in a modular form adapted for selective removable engagement to a ventilator. The apparatus includes a gas inlet port, a gas delivery port, a pressure sensing port, and a thermoelectric cooler. The inlet port is fluidly connectible to a source of therapeutic breathing gas at an external end and is fluidly connectible to an inlet of the ventilator at an internal end. The delivery port is fluidly connectible to a patient circuit at an external end and is fluidly connectable to an outlet of the ventilator at an internal end. The pressure sensing port is fluidly connectible to both a pressure sensing port of the ventilator and to the patient circuit. The apparatus may further include a cooling fluid system operative to circulate either a gas or liquid coolant along at least a portion of a multi-lumen tube integrated into the patient circuit.

An improved fluid flow gauging device includes a light enhanced acrylic block flow tube to optimize visualization of pressure readings. An LED or other light source is fitted to the top of the flow tube and illuminates a float or bobbin from above to provide more accurate readings, especially in low light conditions such as modern operating rooms. In addition, the light enhanced flow tube provides a mechanical backup in the case of failure of newer electronic systems and visually matches the graphical flow display, simultaneously providing a double-check of the electronic system.

A heating apparatus includes a heating element (48) which converts electrical power to heat energy, a heatable element (44) having a first surface and a second surface, and a dielectric laminate layer (46) between the heating element and the first surface of the heatable element, wherein the dielectric laminate layer (46) is thermally conductive to transfer heat energy from the heating element (48) to the heatable element (44), and wherein the second surface of the heatable element is configured heat a liquid in a container.
