The present invention provides an improved visual laryngeal mask comprising a tube, an end of the tube is provided with a fixing seat. The fixing seat is provided with an airbag, and the fixing seat has a recess which is provided with an airway opening. An imaging cavity extends longitudinally inside an inner wall of the tube. The imaging cavity has a built-in imaging device, and the imaging cavity protrudes forward relative to the airway opening to form a stopper which prevents an epiglottis from blocking the imaging device. A front end of the stopper is concaved to form a recess, and an opening of the imaging cavity is located at a low point of the recess.

A liquid ventilation system includes a reservoir holding a perfluorochemical (“PFC”) fluid, and a suction pump connected to the reservoir to reduce pressure within the reservoir. A sensor is configured to measure an intra-lung pressure. An appliance is configured to be disposed within a patient. The appliance carries an injector to supply the PFC fluid through the appliance. An extraction valve is disposed on an extraction line between the appliance and the reservoir. The extraction valve is arrangeable between a first position enabling fluid communication from the appliance to the reservoir and a second position disabling fluid communication from the appliance to the reservoir.

An endotracheal tube apparatus according to an example of this disclosure includes a brace for attachment to a patient's face, a support extending from the brace and including a groove for receiving an endotracheal tube. A clamp surrounds the support and the endotracheal tube. The clamp is comprised of a polymeric material

A dispenser for powdery substances contained in a separate package that has a container part with removable container cover, wherein an aspirated air flow is further sucked predominantly through the container part after removal of the container cover from the container part, such that two air flows entering through slits in a lid that can be pivoted around a pivoting axis evacuate the container part from its two ends, and after merging enter a vortex chamber upstream from a mouthpiece. Outside air inlet openings for a third air flow are formed in a housing part covered by the lid in a radial extension to the pivoting axis.

A suction device for use with a medical device may include a suction device body and an extension. The suction device body may include a first lumen positioned therein and including a plurality of holes. The extension may include a second lumen positioned therein and may be coupled to the suction device body and configured to facilitate connection of the suction device body to a suction line. The second lumen may be in communication with/open to the first lumen and the suction line may be adapted for connection to a pump configured to apply a negative pressure to the first and second lumens. The suction device may evacuate fluids and/or solids from a patient in an area proximate to the suction device.

A suction-target guide pipe that is connected to a suction tube of a suction device includes a guide-pipe main body that includes a connecting portion to be connected to the suction tube, a lid that is provided at an end of the guide-pipe main body and that has an outer peripheral surface and an opening on a distal end side, the outer peripheral surface being formed of a tapered surface whose diameter increases from the distal end to a proximal end, and an end cap that is movable so as to open and close the opening of the lid via a connection cord that is connected to an end of the lid. These features are provided to more easily achieve minimally invasive suctioning of a suction target.

An airway device includes an outertube and a scope channel partially enclosed by the outertube. An intraluminal space in the outertube, not occupied by the scope channel, provides a passageway for air flow to the patient. An esophageal cuff is disposed distally on the scope channel. When inflated, the esophageal cuff secures the airway device in the proximal esophagus of the patient and helps to prevent gastric reflux by mechanically blocking gastric content from entering into the larynx. An inflatable bladder is attached at an anterior surface of the scope channel between the esophageal cuff and a distal opening of the outertube. When inflated, the bladder forms a tubular ring that pushes against the epiglottis and/or other soft tissue towards a wall of the hypopharynx to produce an unhindered air passage into the patient's trachea.

An airway management device comprising a body having a proximal end for receiving an oxygen supply tube and an distal end for insertion into a trachea of a patient; said body including a linear portion adjacent to the proximal end and a curved portion adjacent to the distal end; said body including an external shell and having a first bore through said shell for receiving the oxygen supply tube; wherein flexural strength for said airway management device is provided by said shell.

A fluid dispensing catheter includes an inner member defining a first passage and an outer member defining a second passage. The inner member is disposed within the second passage. The fluid dispensing catheter also includes a plug having a proximal section positioned within the first passage and a distal section extending distally from the proximal section. The distal section is positioned outside of the first passage and within the second passage.
