Publication number: 20120285463Abstract: A patient interface for patient ventilation comprises a frame portion and a head strap system. The frame portion is for surrounding oral and nasal regions of a patient. The head strap system is configured for coupling from a left lateral portion of the patient interface, around a posterior skull of a patient, and to a right lateral portion of the frame portion such that in response to donning of the patient interface, the head strap system supplies a securing force to secure the frame portion in a position over nasal and oral cavities of the patient, the head strap is also configured to retain a head-shape when not in use to enable intuitive donning on the patient.Type: ApplicationFiled: May 11, 2011Publication date: November 15, 2012Inventors: Thomas Dillingham, Christopher M.

Patent number: 8281785Abstract: Breathing equipment (10) for use in conventional operating room procedures comprises a flexible breathing bag (12) connected at one end (12.1) via a gas redirecting connector (14) to a gas guiding tube (16) and at the opposite end to a flexible exhaust gas bridging tube (18) forming part of a gas removal conduit (20) used for the remote venting of exhaled gas via a remote discharge tube (22) also forming part of the conduit (20). A breathing piece (28) is situated at the free end of the tube (16). An inhalation gas supply tube (24) passes within the tube (22) and via the connector (14) into the gas guiding tube (16) up to a position of discharge in close proximity of a user. The connector (14) is formed to cause exhaled gases from the piece (28) to pass along the tube (16) and through the bag (12) prior to remote venting to enable use of the ‘feel’ of the bag (12) during breathing assistance.Type: GrantFiled: April 28, 2006Date of Patent: October 9, 2012Inventor: Pawel Wisniewski
