Patent number: 9662001Abstract: A laryngoscope insertion section comprising a tube guide including at least an inferior tube guiding member and a superior tube guiding member, wherein the thickness of the insertion section in a first region is less than the external diameter of the largest diameter endotracheal tube in an operating range of endotracheal tube sizes plus the thickness of the inferior tube guiding member plus the thickness of the superior tube guiding member. Typically, the insertion section comprises an elongate member and the tube guide is lateral of the elongate member. Typically, an endotracheal tube is retained within the tube guide in flexural tension.Type: GrantFiled: November 30, 2015Date of Patent: May 30, 2017Assignee: Aircraft Medical LimitedInventors: Matthew John Ross McGrath, Morgan James Walker

Patent number: 9656035Abstract: Thus far, it has not been possible to produce laryngeal masks having a supraglottic tube as a one-piece unit. If the supraglottic tube (2) is provided with three lumens (4, 5, 6), the center one (6) of which has no passage to the respiration space (10), a solution is proposed. What is proposed is that the center guide lumen is provided with a longitudinal slit (8) extending from the distal end (9) to the laryngeal mask head (3). A connecting web can be attached between two cores or sliders forming the lumens, generating the desired stability in order to maintain the pressing power tool state without deformation.Type: GrantFiled: May 29, 2013Date of Patent: May 23, 2017Assignee: Singularity AGInventor: Werner F.

Device for evacuating and/or monitoring gas leaking from a patient during surgery or anesthetization
Patent number: 9622683Abstract: A system is described herein for evacuating gas as it is leaking from a patient's airway. The system comprises a gas evacuation flowpath configured for collecting a gas flow escaping from the patient when inserted into the patient's airway. A vacuum source is connected to the gas evacuation flowpath. Devices that may be employed as part of the system and a method for evacuating gas from a patient are also described.Type: GrantFiled: July 11, 2013Date of Patent: April 18, 2017Assignee: FINANCIAL CONSULTANTS LLCInventors: Peter James Wachtell, Kevin Gerard Shea, Owen Francis Shea -
Patent number: 9597472Abstract: An endotracheal tube comprising a flexible hollow tube with a spiral slit traversing a substantial length of the tube. The slit has edges that separate to create an opening by which the tube may be spiral wound onto a medical device, such as a fiber optic bronchoscope, that is in use in a pharynx passage. The angle of the slit is preferably in the range of 30-60 degrees.Type: GrantFiled: April 25, 2014Date of Patent: March 21, 2017Inventor: Irving Mizus

Patent number: 9579477Abstract: A tracheal tube apparatus includes a cannula having first and second ends. An inflatable cuff is formed on the cannula between the first and second ends. A conduit extends from the cuff for introducing an inflating fluid into the cuff when it is desired to inflate the cuff and removing inflating fluid from the cuff when it is desired to deflate the cuff. A gauge for indicating the inflation pressure of the cuff is coupled in the conduit.Type: GrantFiled: June 2, 2015Date of Patent: February 28, 2017Assignee: HANSA MEDICAL PRODUCTS, INC.Inventors: Eric D. Blom, Brad H. Quinn

Patent number: 9572752Abstract: A medical port assembly having a body assembly with a top wall, a bottom wall, first and second walls, and an interior wall. The body assembly further has an exterior wall and an interior adhesive wall. The interior adhesive wall has adhesive means. A permeable wall comprises a slit protected by an overlapping flap. The interior wall and the permeable wall define a cavity. A protective cover covers the interior adhesive wall and/or the cavity. The protective cover adheres to the adhesive. A feeding tube is positioned through the slit. The feeding tube has a distal end, an external retention ring, and at least one port defined as a feeding port, a medication port, or a fluid port. When not utilized, the feeding tube is stored within the cavity.Type: GrantFiled: July 1, 2015Date of Patent: February 21, 2017Inventor: Yvonne Garcia

Patent number: 9492310Abstract: A device for receipt in a user's mouth includes a tongue engagement element having a front region, a rear region, and side regions that define an opening for receiving a user's tongue, means for retaining the user's tongue in a forward position, and means for changing the size of the opening. The tongue engagement element is shaped such that when placed in a user's mouth, the rear region extends over the user's tongue and the front region extends under the user's tongue. A method of securing a tongue engagement element in a user's mouth includes moving an expanded tongue engagement element under a front region of a tongue and over a rear region of the tongue, and allowing the tongue engagement element to return toward a non-expanded state. The tongue engagement element acts to resist rearward motion of the tongue.Type: GrantFiled: October 2, 2013Date of Patent: November 15, 2016Assignee: Sleepy, Inc.Inventors: Joshua Makower, Earl A.
