A device (1) for the tracheal intubation of and the administration of ventilation to a patient for rapid volume-compensating sealing of the trachea, wherein the sealing surfaces of a preferably fully and residually formed balloon-like film body (4) abut the wall of the trachea with a sealing pressure of the balloon (4) which is as constant as possible and follow the thoracic pressure acting on the balloon with the least possible time latency with regard to corresponding fluctuations of the balloon inflation pressure, and the trachea is kept sealed under such dynamic fluctuations or respiration synchronously alternating fluctuations of the balloon inflation pressure. This is enabled by a defined large lumen (7, 5) supply of the balloon inflation medium, the supplying lumen being measured in such a way that a sealing pressure-maintaining extracorporeal volume compensation that works in a time synchronous manner can be achieved in the sealing balloon element.

The present invention relates to a strap member (28a-c) for use in a patient interface (10) for supplying a pressurized flow of breathable gas to an airway of a patient (12), wherein the strap member (28a-c) is configured to secure the patient interface (10) to the head of the patient (12) and comprises: —a strap portion (38) having (i) a first side (40) that is configured to contact the face of the patient (12) during use, (ii) an internal chamber forming a cavity (30), and (iii) a plurality of openings (44) which are fluidly connected to the cavity (30) and arranged at the first side (40); and —a connector (32) for fluidly connecting the cavity (30) to the pressurized flow of breathable gas supplied to the airway of the patient (12).

An appliance (1) for enteral nutrition by means of a probe of the type comprising a tubular element of elongated shape and substantially flexible which defines a feeding channel open at the extremities for the introduction of nutritional substances in the stomach of a patient and which comprises at least a first inflatable balloon for detecting the pressure inside the oesophagus of a patient, the tubular element comprising at least a first inlet/outlet mouth for the air in/from the first balloon, the appliance (1) further comprising: at least a pneumatic circuit (3) having pumping means (4) associable at least with the first inlet/outlet mouth for inflating/deflating the first balloon; processing means (8) comprising: detection means which can be connected to the first balloon to detect the patient's oesophageal pressure (p.sub.es); reading means of the pressure of the respiratory tract (p.sub.aw) which can be connected to an external detection device; calculation means operatively connected to the detection means and to the reading means and able to calculate at least the transpulmonary pressure (p.sub.tp); graphic display means (10) operatively connected to the processing means (8) and able to display at least one of the oesophageal pressure (p.sub.es), the pressure of the respiratory tract (p.sub.aw) and the transpulmonary pressure (p.sub.tp).

The present invention relates generally to medical devices, methods, and kits. More particularly, the present invention relates to improved endotracheal tubes or patient ventilation tubes which prevent the leakage of proximal secretions to the distal airways.

Device for gravity-driven, particularly continuous, control of the filling pressure in a balloon catheter (3), comprising: a balloon reservoir that is statically loaded with a vertically guided weight guide or stamp (9) that weighs vertically on the balloon reservoir, wherein said weight guide or stamp is designed to carry vertically arranged and therewith plumb-vertically acting weight elements (8), and wherein the balloon reservoir is guided in a cylindrical shell (6).

A tracheostomy tube has an inflatable sealing cuff (11) towards its patient end (6) and a fluid-permeable cuff (31) mounted on the shaft (1) above the inflatable cuff. The fluid-permeable cuff (31) contains hydrogel granules (32) that absorb moisture in the trachea (T) and help reduces the amount of secretions leaking past the sealing cuff (11). When the tube is to be withdrawn from the trachea (T) the lower, inflatable cuff (11) is deflated allowing the upper, fluid-permeable cuff (31) to be flattened against the outside of the lower cuff.

A system for measuring cardiovascular data includes an elongate member having a channel, a first expandable member carried by the elongate member and movable between a collapsed state and an expanded state by adjustment initiated externally of a subject, a first sensor disposed on a surface of the elongate member, second and third sensors disposed on a surface of the first expandable, a first optical sensor located at a first location in relation to the distal end of the elongate member and configured for obtaining photoplethsmographic data, and wherein the first expandable member in its expanded state is configured to interface with the subject's larynx for delivery of at least oxygen gas into the respiratory system of the subject, and the second and third sensors are configured to contact tissue in proximity to the larynx when the first expandable member is in its expanded state.

A syringe assembly or inflation device that includes a detachable housing. A pressure-sensing syringe assembly or inflation device can include both a syringe barrel and a housing that is coupled to the syringe barrel in a locked configuration. The inflation device can transition from the locked configuration to the unlocked configuration in which the housing is separable from the syringe barrel. Related methods are also disclosed.

A cleaning catheter includes an inflatable element and an input module, which includes an inflation chamber coupled in fluid communication with the inflatable element. A flow regulator defines a suction port coupleable in fluid communication with a suction source. A mechanical suction-control button is configured to assume at least first and second spatial positions. A mechanical inflation-control button is configured to mechanically and non-electrically increase pressure in the interior of the inflation chamber during a transition of the mechanical inflation-control button from a first spatial position to a second spatial position; and a reversibly-engageable linking element, which is moveable with respect to the mechanical suction-control button and the mechanical inflation-control button, and is configured to assume at least a first spatial position, in which the linking element does not engage the mechanical suction-control button when the mechanical suction-control button is in its second spatial position; and a second spatial position.

An airway stabilization system attachable to any airway device to maintain an airway in a patient and which prevents clinically significant movement of the airway device with respect to the patient's vocal cords in response to the application of significant forces in any direction to the device, be they longitudinal, torsional/rotational or bending. The system includes an improved airway device and an improved securing device having interactive components that cooperate integrally with and engage one another to provide unparalleled strength and stability against movement. The securing device includes a unique stabilizer configured to releaseably engage a retention structure on the airway device with a simple twist. A connector device connects the system to a source of ventilatory air without constricting the airway device.
