Tube placement in non-invasive ventilation

摘要

Described herein is a mask for delivery of gas, such as oxygen, to a patient and useable in a naso-gastric intubation procedure without disruption of the seal between the mask and the patient's face. The body of the mask includes a fenestration or opening through which the naso-gastric tube may be inserted. The fenestration is preferably shaped to support the tube in a manner that is comfortable for the patient and that eliminates or minimizes the amount of gas lost to the atmosphere outside the mask. In at least some embodiments, the fenestration is closed when a tube is not inserted therethrough so that the mask may be used normally without loss of the gas through the fenestration.

主权项

1. A non-invasive ventilation patient interface, said patient interface comprising:
a frame configured for coupling with a head strap system, wherein said head strap system is configured for supplying a securing force to secure said patient interface in a position over a respiratory opening of a patient; a facial skin interface coupled with said frame and comprising a removable skin-contacting portion configured for interfacing with facial skin of said patient, the facial skin interface comprises ends terminating, when in use, on opposing lateral edges of a nasal bridge of said patient; a self-sealing tube insertion region coupled with the removable skin-contacting portion and configured (i) for self-sealing about a tube disposed between said facial skin and said removable skin-contacting portion such that said securing force is diverted around said tube while said tube is in said self-sealing tube insertion region and (ii) to self-seal an opening, that receives the tube, by expanding to fill the opening when the tube is not present such that leakage of gases through the opening is restricted; and an adhesive disposed in the self-sealing tube insertion region within the opening such that the self-sealing tube insertion region adheres to the tube when the tube extends through the opening.
