An exemplary suction catheter is provided. The suction catheter includes a body defining a tubular structure, the body including a proximal end and a distal end on opposing sides of the body. The suction catheter includes a first suction hole formed in the body and spaced from the distal end by a first distance, a second suction hole formed in the body and spaced from the distal end by a second distance, a third suction hole formed in the body and spaced from the distal end by a third distance, and a fourth suction hole formed in the body and spaced from the distal end by a fourth distance. The fourth distance is greater than the first, second and third distances, the third distance is greater than the first and second distances, and the second distance is greater than the first distance.

The present invention provides medical devices comprising at least one visualization device sealed to, attached to or otherwise combined with at least one of the following second devices: an oral airway, ventilating mask, urinary catheter, trocar, a tool tube, and a medical glove. The present invention also provides methods for rapid and accurate placement of a medical device in a patient and continuous real time monitoring, including a remote monitoring, of the patient after the placement.

A pulmonary secretion clearing airway structure and related airway management system is disclosed that has a double lumen portion which each lumen of the double lumen portion operably secured to an airway management system so that inspiratory fluid (air/oxygen mixtures, with or without added water vapor) is delivered to the distal end of the ventilation catheter through one of the two lumens and expired inspiratory fluid, pulmonary secretions, and pulmonary fluids are removed from the patient through the other lumen. The expiratory fluid pathway preferably includes a secretion collection system for removing the pulmonary secretions and the like from the pathway, thereby improving operation and safety of the system. The airway structure can be a ventilation catheter or a supraglottic airway system such as laryngeal mask and the like.

A sanitary extubation cover used to cover an endotracheal tube and a patient's face in order to accommodate sanitary extubation. The sanitary extubation cover includes a mask and a cover which covers the endotracheal tube. If the patient coughs, the cough would be directed into the mask and the endotracheal tube (which is covered by the cover) but contaminants from the cough would be suppressed from spreading into the open air.

A connector a medication dispenser includes a first portion coupling the connector to the medication dispenser and a second portion configured to couple the connector to a breathing apparatus. The first portion has a first opening with a first shape and a first size. The second portion has a second opening with a second shape and a second size that are different from the first shape and the first size of the first opening, respectively.

A cannula plugging device for rehabilitation after tracheotomy relates to the field of medical devices. The cannula plugging device includes a plugging device bracket. An outer wall of the plugging device bracket is fitted with a ring-shaped outer airbag. An inner wall of the plugging device bracket is fitted with a ring-shaped inner airbag. Two inflation tubes connecting the outer airbag and the inner airbag respectively are fitted on the plugging device bracket. The present invention makes the outer airbag and the inner wall of tracheotomy cannula pressed together by inflating the outer airbag. By gradually inflating the inner airbag and adjusting the size of the inner diameter of the lumen, the opening of the trachea gradually changes, so that the patient can gradually adapt to the process of plugging the cannula.

A sanitary extubation cover used to cover an endotracheal tube and a patient's face in order to accommodate sanitary extubation. The sanitary extubation cover includes a mask and a cover which covers the endotracheal tube. If the patient coughs, the cough would be directed into the mask and the endotracheal tube (which is covered by the cover) but contaminants from the cough would be suppressed from spreading into the open air. The mask can have an air cushion at the bottom of the mask in order to securely press against the patient's face. The mask can also have a solid silicone base at the bottom of the mask in order to securely press against the patient's face.

An endotracheal tube has a curved tube body and an oblique cutting surface. The curved tube body has a front end, and the curved tube body has a center axis, an inner axis and an outer axis. The oblique cutting surface has a tip, and the oblique cutting surface is located at the front end and has the following characteristics: the oblique cutting surface has a circular projection surface in the vertical plane and a tip projection point on the circumference of the circular projection surface, the inner axis has an inner axis projection point on the circumference of the circular projection surface, and the tip projection point and the inner axis projection point have an angle θ, where 15°<θ<45°.

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 insertion guide facilitates insertion of an endotracheal tube (ETT) into the trachea of a patient instead of the esophagus of the patient. The ETT includes an elongated, somewhat flexible, generally hollow tube and the insertion guide includes an elongated, solid and relatively rigid shaft that is configured to be positioned within the hollow tube of the ETT. The shaft is provided with a radiused portion and/or an angled portion adjacent a distal end of the insertion guide that protrudes outwardly beyond a distal end of the ETT. The radiused portion and/or the angled portion of the shaft facilitate insertion of the distal end of the ETT past the epiglottis and into the trachea of the patient instead of into the esophagus of the patient.
