Disclosed is a multifunctional balloon dilatation catheter for intracorporeal membrane oxygenation, comprising: a catheter hub, a dilatation balloon, and M channels. The M channels comprise at least a balloon dilatation channel for dilating the narrowed part of the airway, a positioning & detection channel for positioning or detecting while inserting, a supply channel for continuous oxygen supply or drug administration to the patient, and a secretion removal channel for removing secretions from the airway. The catheter hub is a multi-channel connection device, through which the M channels are respectively connected to the external therapeutic devices of the catheter. The catheter is inserted into a bronchiole of the lungs. When using the catheter for emergency treatment of patients with pneumonia, especially COVID-19, measures such as airway dilatation, oxygen supply, sputum suction and biopsy can be simultaneously performed, thereby improving the survival rate of patients and reducing lung damage.

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.

Airway devices, systems, and methods are provided that can achieve ventilation of lungs through a mask that seals around the glottis and connects to a flexible airway channel, while also providing evacuation of gastric and/or pharyngeal body fluid and/or blood during upper airway surgeries or procedures.

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.

An add-on device and method for an Endo-Tracheal Tube (ETT), the add-on device including a lengthy body having a major arc-shaped cross section sized and shaped to tightly fit over an ETT, at least one longitudinal cavity passing along the lengthy body, including a distal suction cavity ending with a suction inlet at a distal end of the lengthy body; and a distal suction outlet channel extending from a proximal end of the lengthy body, the channel is a continuous extension of the distal suction cavity and configured to provide suction to the distal suction cavity. The add-on device senses moisture at a distal end of the add-on device, and in case of detection of excessive wetness, provides suction to the distal end of the device through a cavity passing along the device, the suction is provided via a suction outlet channel extending from a proximal end of the device.

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.
