A laryngeal mask airway (LMA) device includes a backplate, an inflatable balloon, an airway tube, and a non-inflatable skeleton, which extends anteriorly from the backplate, and which is shaped so as to define a skeleton anterior side that has a pre-formed shape. A distal end of an inflation tube is coupled in fluid communication with (i) an interior of the inflatable balloon for supplying air to the inflatable balloon, and (ii) at least a portion of the skeleton anterior side. The inflatable balloon is shaped so as to define an inflatable annular cuff which (a) covers at least a portion of the skeleton anterior side, and (b) has a cuff anterior side that is configured to form a seal around a laryngeal inlet of a patient when the inflatable annular cuff is disposed at an LMA-insertion location within a throat of the patient. Other embodiments are also described.

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 esophagus 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).

An artificial airway device 1 to facilitate lung ventilation of a patient, comprising an airway tube 2 including an airway lumen 3, a mask 4 at one end of the airway tube, the mask including a backplate 5 and having a peripheral formation 6 capable of forming a seal around the circumference of the laryngeal inlet, the peripheral formation surrounding a hollow interior space or lumen 7 of the mask and the airway lumen 3 opening into the lumen of the mask, wherein the airway tube 2 comprises an outer tube part 201 and an inner core 202, the inner core 202 defining partly or completely the airway lumen.

A laryngeal mask airway device (LMA) is disclosed comprising a ventilation conduit having operatively upper and lower ends, and a mask at the operatively lower end of the ventilation conduit. The mask has an inner surface forming a receptacle that is in fluid communication with the ventilation conduit, and an outer oropharyngeal surface facing away from the receptacle. The device includes a separate oropharyngeal suction conduit having an operatively lower end forming a collector defining a plurality of suction openings that extends across the oropharyngeal surface of the mask. In use secretions may be drawn through the suction openings into the oropharyngeal suction conduit for removal from the patient through the oropharyngeal suction conduit.

Intubation devices and methods of intubating a patient are provided. The intubation devices include a laryngeal mask airway (LMA) component having a mask portion and a tube portion and an endotracheal tube (ETT) component positioned in the laryngeal mask airway (LMA) component having a translatable and/or rotatable endotracheal tube. The endotracheal tube can be translated and/or rotated by a manipulation rod extending through the laryngeal mask airway (LMA) component and mounted to the endotracheal tube (ETT). The intubation devices may include inflatable cuffs adapted to manipulate the positioning or orientation of the endotracheal tube and/or to seal openings about the endotracheal tubes. Various ports, passages, and conduits are provided to enhance the use and manipulation of the intubation device.

The invention relates to a positioning sputum suction laryngeal mask. The positioning sputum suction laryngeal mask comprises a mask body and a mask body tube, wherein the mask body comprises a mask body bottom plate and a mask main body arranged on the mask body bottom plate, a central region in the mask main body is provided with a mask body cavity communicated with the mask body tube, a stomach decompression tube corresponding to the stomach mouth is arranged on the back side of the mask body bottom plate, and the stomach decompression tube is isolated from the mask body cavity through the mask body bottom plate. The positioning sputum suction laryngeal mask also comprises a connection suction mechanism capable of realizing negative pressure suction in a gas supply process. The connection suction mechanism comprises a suction connecting tube which is arranged in the mask body bottom plate, and the end, located in the mask body bottom plate, of the suction connecting tube is communicated with the stomach decompression tube. The positioning sputum suction laryngeal mask can be effectively positioned, has lower complexity and usage costs, can ensure the ventilation and sealing effect without air inflation in use, can realize suction of secretions in a ventilation process, can avoid airway blockage caused by epiglottis, and can improve the stability and reliability in use.

A nasal cannula assembly is disclosed having a face mount part, in use resting against a user's face, which includes at least one nasal prong capable of being fitted into a person's nares. The cannula assembly also includes a manifold part, in fluid communication with the face mount part, having a single horizontal side gases entry. In particular, this cannula assembly is for supplying heated, humidified gases to a patient suffering from COPD. A tie or lanyard is disclosed for use with a breathing assistance apparatus such as a nasal cannula, face or nasal mask or tracheostomy connector. The tie or lanyard transfers the weight of the conduits supplying gases to the breathing assistance apparatus from the breathing assistance apparatus and distributes it onto the neck of the patient.

A placement device is provided for causing a catheter to be placed inside of a body. The placement device includes an insertion unit, a transmission unit and a supply member. The supply member includes a supply unit main body, and a projection. A through-hole is formed on the inner peripheral surface of the supply unit main body at a position closer to a distal end side of the supply portion main body than the projection, and the through-hole communicates with an inside of the supply unit main body at the distal end side of the supply unit main body.

A mask assembly is provided for delivering gas to a patient that includes a mask body and a breathing circuit interface. The mask body includes an opening for reception of the gas and includes a seal structure for sealingly engaging with the face of the patient and surrounding at least the nose and mouth of the patient. The breathing circuit interface includes a first portion rotatably connected with the mask body and a second portion that is constructed and arranged to releasably connect with a conduit for delivering the gas to the patient through the opening.
