A laryngeal mask apparatus includes a mask portion, a breathing tube and a suction tube. The suction tube is adapted for connection to a suction-producing device. The suction tube further includes suction ports that suck fluids and secretions from the patient's hypopharyngeal region when suction is created within the interior of the suction tube. The breathing tube is adapted for connection to a ventilating system. Air flows through the breathing tube and into the mask portion. A capillary tube is positioned within the interior of the suction tube. When the mask portion is positioned within a patient's throat and suction is created within interior of the suction tube, the suction ports suck the fluids and secretions in the patient's hypopharyngeal region. At the same time, the suction tube and capillary tube cooperate to provide a stream of air that decreases the direct suction forces on the mucosa of the patient's throat that are caused by the suction ports. The laryngeal mask apparatus includes a scope tube having an interior and an inner tube disposed within the interior of the scope tube. The inner tube is sized for receiving a gastric tube.

An irrigating intraluminal suction inner cannula system for a tracheostomy tube may be a suction-powered system that may be used for suction alone or a combination of rinse and intraluminal suction for tracheostomy tubes in place of conventional catheter-based intraluminal suction. An inner cannula includes chambers, or regions, and holes that facilitate intraluminal suction and cleaning at multiple locations within the tracheostomy tube. It may be applied/actuated by a patient, healthcare worker, caretaker, or via an electronic system either on-demand or on regular or triggered intervals, in either inpatient/hospital or outpatient/ambulatory care setting.

An endotracheal tube (ETT) system and methods are provided. In at least one example, an ETT system may comprise, a tube, inflatable cuff coupled to the tube, and a restrictor. In at least one example the restrictor may comprise one more cavities. In a further example, a restrictor drainage assembly may be coupled to the restrictor, the restrictor drainage assembly configured to drain secretions that may be collected at a collection point formed by the restrictor when the ETT system is positioned in an airway of a patient and in an inflated state.

A nasopharyngeal cannula comprising a body formed by a tubular portion that is curved so as to be inserted into a patient's nostril and a collar for resting on the base of the patient's nostril is described. The cannula also comprises a main channel forming a fluid passage between the collar and the tubular portion of the body and two auxiliary channels formed in the body and extending from the collar into the main channel. Each auxiliary channel opens into the collar at an inlet/outlet port oriented radially in relation to the axis of the main channel such as to be oriented laterally on each side of the patient's nostril when the cannula is in place on the patient.

An intubation and supraglottic airway medical device. The device includes an air tube for ventilation, and a tube for guiding a fiber-optic-probe-scope to the distal end of the device. The distal end of the device is configured with a balloon around the tube system and between a bottom plate and the tube system such that when inflated the distal end of the air-tube is moved and thereby positioning the air-tube distal opening in front of a laryngeal inlet. Additionally, the balloon forms a seal with the surrounding tissue. The device includes a drainage loop and an esophageal blocker preventing aspiration. The air tube distal end can include a lifting plate configured to lift an epiglottis when the balloon is inflated.

A closed suction system module is provided. In one embodiment, the closed suction system module includes a coupling member configured to couple to a suction port of a multi-port manifold or endotracheal tube adapter (e.g., dual-port or tri-port adapter). In one embodiment, the closed suction system module includes a suction catheter configured to clean the interior surfaces of body-inserted tubes or artificial airways (alone or in addition to suctioning natural airways or portions of the respiratory tract or other body lumens). The suction catheter may include a cleaning portion at a distal portion of the suction catheter (e.g., near the distal end or tip of the suction catheter). In some embodiments, the cleaning portion includes at least one expandable cleaning member (e.g., balloon, sleeve, wiper).

Provided is an endotracheal tube, which comprises a baffle, an endotracheal tube body and a pharyngeal suction catheter and is integrally formed. The pharyngeal suction catheter is fixedly connected with an outer wall of the endotracheal tube body. One end of the pharyngeal suction catheter is bent to form a front bent portion, a port of the front bent portion is closed and a side wall of the front bent portion is provided with two suction ports. In the case of oral endotracheal intubation, the pharyngeal suction catheter is introduced to the bottom of the pharynx as the endotracheal tube body is inserted into the weasand, and the pharyngeal suction catheter can stay there for a long period of time, enabling high efficiency of removal of pharyngeal secretions, the reduction of discomfort and adsorption injury of the patient, and the reduction of nursing workload.

A method for guiding suction of an obstruction may comprise emitting sound waves from a sound generator into a tube, detecting returning acoustic reflections with at least one sound receiver, analyzing, using a processor, timings and amplitudes of the returning acoustic reflections to determine a location and size of an obstruction within the tube and a location of a tip of a suction catheter, and guiding the suction catheter to the obstruction.

The present invention discloses an artificial airway sputum scab cleaner including a connection hub, a display window, a detection tube, a sputum suction tube, a sputum suction device, a probe head a hooking device, a light beam device and a camera device; the hooking device includes a hooking channel, a hooking spoon, a push rod and a permanent magnet, an iron sheet, a first coil. The invention has the beneficial effects of simple operation, real-time monitoring, and accurate and rapid cleaning of foreign matters, thus greatly saving the treatment time, reducing the intensity of nursing work, reducing the occurrence of complications and greatly reducing the pains of patients.

Devices and methods for allowing for improved assisted ventilation of a patient. The methods and devices provide a number of benefits over conventional approaches for assisted ventilation. For example, the methods and devices described herein permit blind insertion of a device that can allow ventilation regardless of whether the device is positioned within a trachea or an esophagus. In addition, the methods and device allow for timed delivery of ventilations based on a condition of a thoracic cavity to increase the amount and efficiency of blood flow during a resuscitation procedure.
