Patent number: 7337777Abstract: A simple and compact device permits a single rescuer to quickly place a prone patient's airway in an optimal, open configuration. The device consists of a reversibly collapsed neck support that can rapidly be placed underneath the neck of an unconscious patient lying prone on his back. The collapsed support can be inflated to returned it to a not collapsed state for elevating a portion of the patient's neck. The support is shaped to come to an apex so that the pressure is applied to a restricted region of the neck. When gentle elevating pressure is applied to a small region of the neck, the neck “fulcrums” with the head remaining in contact with the ground and the free portion of the neck being elevated. This results in the optimum extension to open the airway without having to pull on the patient's jaw. Once the airway is open, it is relatively simple to place a tight fitting resuscitation mask over the patient's mouth.Type: GrantFiled: March 29, 2005Date of Patent: March 4, 2008Inventor: Steven Islava

Patent number: 7032596Abstract: A cardiopulmonary resuscitation device and method that combines artificial, emergency ventilation of a patient's lungs with chest compressions on the patient's sternum area. The device includes a self-inflating bag having a top side, a bottom side, and an outlet port through which the content of the bag is forced when the top side of the bag is pushed toward the bottom side of the bag; target indicia on the self-inflating bag to indicate the proper position of the self-inflating bag on the patient's sternum area and to indicate the proper location on the self-inflating bag for applying force to the top side of the self-inflating bag; a face mask for placement over the patient's mouth and nose; and a tube extending from the outlet port of the self-inflating bag to the face mask.Type: GrantFiled: April 6, 2004Date of Patent: April 25, 2006Inventors: Darrell K. Thompson, Phyllis D. Thompson

Patent number: 6986349Abstract: A method for increasing circulation in a breathing person utilizes a valve system that is interfaced to the person's airway and is configured to decrease or prevent respiratory gas flow to the person's lungs during at least a portion of an inhalation event. The person is permitted to inhale and exhale through the valve system. During inhalation, the valve system functions to produce a vacuum within the thorax to increase blood flow back to the right heart of the person, thereby increasing cardiac output and blood circulation.Type: GrantFiled: August 19, 2002Date of Patent: January 17, 2006Assignee: Advanced Circulatory Systems, Inc.Inventor: Keith G. Lurie

Publication number: 20040200473Abstract: A demonstration device comprises a base having a front side, a back side, a respiratory port, a circulation port, a heart port and at least one lung port. The heart port is fluidly connected to the circulation port, and the lung port is fluidly connected to the respiratory port. A compressible member is sealed to the front side of the base to define a chamber over the lung port and the heart port. A lung member is disposed over the lung port, and a heart member is disposed over the heart port. In this way, when the compressible member is compressed and released, the lung member deflates and inflates and the heart member deflates and inflates.Type: ApplicationFiled: April 8, 2003Publication date: October 14, 2004Applicant: CPRx LLCInventors: Keith G. Lurie, Michele D. Perpich, Thomas E. Kramer

Patent number: 6776160Abstract: An intake valve includes a bladder having a face piece coupled to one end and an opening formed in the other end, a cover attached to the other end of the bladder and having a port coupled to an air reservoir and having a hub coupled to a container, which may be used for pumping air into the bladder when the air in the air reservoir has been consumed. The cover has a check valve for air to flow into the cover when the container is expanded, and for pumping air into the bladder when the container is squeezed. Another check valve may be used for outward flowing of excess air.Type: GrantFiled: May 14, 2002Date of Patent: August 17, 2004Assignee: Galemed CorporationInventor: Chih Hua Wang

Patent number: 6776156Abstract: A method for administering a drug to a patient comprises coupling a valve system to the patient's airway. The valve system is configured to prevent or impede respiratory gases from flowing into the lungs for at least some time such that the intrathoracic pressure is less than atmospheric pressure. A drug is introduced into the patient, and the intrathoracic pressure is lowered using the valve system to cause blood to flow into the thorax and thereby increasing vital organ perfusion to enhance the circulation of the drug.Type: GrantFiled: September 28, 2001Date of Patent: August 17, 2004Assignee: Advanced Circulatory Systems, Inc.Inventors: Keith G. Lurie, Wolfgang Voelckel

Publication number: 20040094150Abstract: A manually-operable resuscitator operable also to inject medication into air being supplied to a patient. The said resuscitator has a resiliently compressible air bag having an inlet and an outlet. The inlet has a one-way valve through which air passes into the bag from the atmosphere and a patient valve through which air flows in passing from the bag to the patient. The patient valve has a one-way valve member through which air flows in passing from the bag to the patient. The patient valve also has a passage extending from the atmosphere to the interior thereof adjacent to the one-way valve member and upstream thereof through which medication can be injected into the air as it passes from the bag to the one-way valve member.Type: ApplicationFiled: July 7, 2003Publication date: May 20, 2004Inventor: Stephen Flynn

Patent number: 6691703Abstract: A resuscitation device for providing a barrier between a rescuer and a patient requiring mouth-to-mouth resuscitation. This resuscitation device includes an inflatable portion which when inflated extends in the breathing direction between the rescuer and the patient so as to be placed around at least one breathing organ of the victim. An inflation member receives airflow from the rescuer to inflate the inflatable portion. In this resuscitation device, a valve assembly permits airflow from the rescuer to the patient and diverts the exhalation and body fluids of the patient from reaching the rescuer. An additional barrier member can also be provided for shielding the rescuer from the patient.Type: GrantFiled: January 31, 2001Date of Patent: February 17, 2004Assignee: Laerdal Medical CorporationInventors: Larry T. McKinney, James R. Traut, John G. Cline, Sean Landis Phillips, Andrew Serbinski, Mirzat Koc, Mark Rosen
