The present disclosure pertains to a portable handheld pressure support system configured to deliver a pressurized flow of breathable gas to the airway of a subject. The pressure support system is configured to treat COPD and/or other patients suffering from dyspnea and/or other conditions. The pressure support system is configured to be small and lightweight so that a subject may carry the system and use the system as needed without requiring a device to be worn on the face. The present disclosure contemplates that the portable handheld pressure support system may be used to treat symptoms and/or conditions related to dyspnea, and/or for other uses. In one embodiment, the system comprises one or more of a pressure generator, a subject interface, one or more sensors, one or more processors, a user interface, electronic storage, a portable power source, a housing, a handle, and/or other components.

A catheter connector assembly which may be included with a corporeal drainage system, and a method of draining fluid from a bodily cavity. The catheter connector assembly may include a catheter connector and a drainage line connector. The catheter connector may include a connector body with a coupling feature, a deformable sealing element, and a retaining member. The drainage line connector may include a drainage line body first and second hinge clips, and an actuator. The actuator is designed to deform the deformable sealing element when the drainage line connector is coupled to the catheter connector.

A multipurpose device for preventing or treating deep vein thrombosis, extremity edema, and breathing conditions is provided herein. The multipurpose device includes a respiratory device, such as a flutter valve or a spirometer, having a mouthpiece or nasal breathing piece, a pump connected to the respiratory device by first tubing, a release valve connected to the pump by second tubing, and one or more third tubing(s) connected to the release valve.

A medical vaporizer is provided. In one embodiment, dual-purpose sensors are employed, such as in a configuration in which one is positioned in the mixed gas flow channel and one is positioned in the main gas flow channel. The sensors provide measurements that may be used to determine both gas flow and gas concentration in the mixed and main gas channels, even when the identity and/or properties of the gas in the main gas channel are unknown. The measurements derived from the dual-purpose sensors may be used to measure and report the total anesthetic being delivered at the vaporizer output and/or improve vaporizer accuracy.

The present application provides a portable gas supply device and a respiratory assistance system. The portable gas supply device comprises a gas source and a gas transport unit; the gas source is configured to provide purified air; the gas transport unit comprises a gas transport mechanism, a buffer airbag, and a first gas check mechanism; the gas transport mechanism has a gas passage, an inlet end of the gas passage being connected to the gas source, and an outlet end thereof being used for outputting the purified air; the buffer airbag is communicated with the gas passage or the gas source; the first gas check mechanism is mounted in the gas passage and is configured to be in one-way conduction from the inlet end to the outlet end.

A CPAP device includes a flow generator including an outlet, a humidifier including an inlet, and an adaptor connector between the outlet of the flow generator and the inlet of the humidifier. The connector includes a flexible and conformable sealing portion that is movable to accommodate misalignment.

The invention allows for considerably improving the efficiency of inhalation treatment of various diseases and conditions in pulmonology, therapy, intensive treatment, anesthesiology, and sports medicine and is provided with new integral technical solutions while employing the opportunities of microelectronic technology and modern components. A modular structure of the apparatus simplifies its manufacture, ensures the ease of setting it up, and operation in various operating modes. When using the invention, monitoring of the ventilation indicators and patient condition with achieving his high safety level may be ensured; in sports medicine a problem of rehabilitation and training of athletes with the background of extreme loads and increased ventilation indicators is solved.

A patient interface for sealed delivery of a flow of air to ameliorate sleep disordered breathing may include: a seal-forming structure to form a pneumatic seal with the entrance to the patient's airways; a positioning and stabilising structure to maintain the seal-forming structure in sealing contact with an area surrounding the entrance to the patient's airways; a plenum chamber pressurised at a pressure above ambient pressure in use; a connection port for the delivery of the flow of breathable gas into the patient interface; and a device positioned within a breathing chamber defined, at least in part, by the seal-forming structure and the plenum chamber, wherein the device divides the breathing chamber into a posterior chamber and an anterior chamber, and wherein the device comprises a plurality of apertures such that turbulence of the air in the posterior chamber is less than turbulence in the air in the anterior chamber.

The invention relates to an ergonomic foot pedal and to apparatuses for manual ventilation. In an embodiment, the invention provides a compact and integrated foot pedal that enables a care provider to provide positive pressure ventilation to a subject's airways and lungs, and to optionally apply suction for the purpose of aspirating mucous, secretions, meconium, blood, fluids or other such materials from a patientspecifically from airways.

A patient interface for delivering breathable gas to a patient includes a sealing portion including a nose tip engagement portion adapted to form a seal with the patient's nose tip, an upper lip engagement portion adapted to form a seal with the patient's upper lip and/or base of the patient's nares, and nostril engagement flaps adapted to form a seal with the patient's nares. The nose tip engagement portion, the upper lip engagement portion, and the nostril engagement flaps are all structured to extend or curve outwardly from a supporting wall defining an air path.
