Patent number: 5735271Abstract: Apparatus and methods are disclosed by which a closed ventilating system accommodates multiple access to the respiratory system of an intubated medical patient. Access to the respiratory system is accomplished via one or more access ports through an attached accessory device in order to ventilate the lungs of the patent with gas or gasses, aspirate secretions from the lungs, oxygenate the lungs, visually inspect selected parts of the respiratory system, sample sputum and gasses, sense parameters such as flow rates, pressure, and temperature, flush the respiratory tract with washing solution, and/or administer medication, gasses, and/or lavage. The embodiments of the present invention may have such accessory devices permanently fixed to the adaptor or may be removable and replaceable. Access control means may be provided whereby one or more access ports are selectively aligned with the adaptor in order to allow passage of an attached accessory device therethrough.Type: GrantFiled: May 22, 1996Date of Patent: April 7, 1998Assignee: Ballard Medical ProductsInventors: Rick D. Lorenzen, Darrel R. Palmer, William R. Houghton, Gerry A. Arambula, David Theron Van Hooser, Richard C. Lambert, Billy M. Jensen, Gene Stewart

Patent number: 5730123Abstract: Apparatus and methods are disclosed by which a closed ventilating system accommodates multiple access to the respiratory system of an intubated medical patient without comprising the closed character of the system. Access to the respiratory system through one or more access sites of the closed system apparatus is provided at proximal adapter ports to ventilate the lungs of the patient with gas or gases, to aspirate secretions from the lungs, to oxygenate the lungs to eliminate or reduce residual co.sub.2 therefrom, to visually inspect selected parts of the respiratory system, to sample sputum and gases, to sense parameters such as flow rates, pressure, and temperature, to flush with washing solution, and/or to administer medication, gases, and/or lavage.Type: GrantFiled: April 21, 1995Date of Patent: March 24, 1998Assignee: Ballard Medical ProductsInventors: Rick D. Lorenzen, Darrel R. Palmer, William R. Houghton, Gerry A. Arambula, David Theron Van Hooser, Richard C. Lambert, Billy M. Jensen, Gene Stewart

Patent number: 5133345Abstract: Apparatus for respiratory therapy, which is particularly useful in a neonatal context, and related methods, the apparatus comprising an adaptor for connection to the exposed fitting of an indwelling endotracheal tube of any one of several types to an aspirating apparatus which may include ventilating capacity. The adaptor includes an appendage by which a lavage solution can be selectively introduced into the lungs of a patient through the indwelling endotracheal tube to loosen secretions without necessarily interrupting the ventilation cycle or requiring that the ventilating circuit be broken. The apparatus also comprises a fitting at one end of an aspirating/ventilating apparatus which has low dead space, alleviating the incidence of inadvertent disconnection and trauma induced by unintended displacement of the end fitting and accommodating not only aspiration and ventilation but also monitoring of certain vital indicators to allow prompt medical response to contraindications.Type: GrantFiled: November 14, 1991Date of Patent: July 28, 1992Assignee: Ballard Medical ProductsInventor: Richard C. Lambert

Patent number: 5029580Abstract: An aspirating/ventilating or aspirating apparatus comprising multi-lumen catheter tubes, for evacuation of lung secretions and for other functions as well. Two and three lumen catheter tubes which comprise three unique distal catheter end structures are disclosed. Material comprising oxygen-containing gas is introduced into the lungs under positive pressure through a first lumen of the catheter tube at a predetermined rate while secretions (and gas) are simultaneously aspirated from the lung into a second lumen by force of negative pressure. Oxygen gas inflow is controlled to equal gas outflow to maintain the partial pressure of oxygen into the lung at a high respiratory level. In a first distal catheter end structure, an oxygen-containing gas is introduced through the first lumen as a circumscribing jet around the second lumen to provide fluid flow turbulence external to a second lumen to improve homogenization of localized secretions resulting in more efficient aspiration.Type: GrantFiled: July 18, 1990Date of Patent: July 9, 1991Assignee: Ballard Medical ProductsInventors: F. Richard Radford, Richard C. Lambert, Darrel Palmer

Patent number: 4938741Abstract: A ventilating/aspirating apparatus, and related methods, the apparatus comprising a catheter tube for evacuation of lung secretions wherein the distal end portion of the catheter tube is disposed at a substantial angle in respect to the remainder of the catheter tube whereby entry into the left lung of a patient may be predictably and accurately tended to without appreciable trauma to the patient. A removable angle retainer is provided for maintaining the configuration of the distal end portion of the catheter tube during storage, prior to use. Radiopaque indicia, selectively located within the wall of the catheter tube, is provided by which the entry of the distal end portion of the catheter tube into the lungs and particularly the left lung of the medical patient can be insured through accurate monitoring visually or by using available radiological techniques.Type: GrantFiled: October 31, 1989Date of Patent: July 3, 1990Assignee: Ballard Medical ProductsInventor: Richard C.
