Publication number: 20110224587Abstract: Apparatus for automatic delivery of chest compressions and ventilation to a patient, the apparatus including: a chest compressing device configured to deliver compression phases during which pressure is applied to compress the chest and decompression phases during which approximately zero pressure is applied to the chest a ventilator configured to deliver positive, negative, or approximately zero pressure to the airway; control circuitry and processor, wherein the circuitry and processor are configured to cause the chest compressing device to repeatedly deliver a set containing a plurality of systolic flow cycles, each systolic flow cycle comprising a systolic decompression phase and a systolic compression phase, and at least one diastolic flow cycle interspersed between sets of systolic flow cycles, each diastolic flow cycle comprising a diastolic decompression phase and a diastolic compression phase, wherein the diastolic decompression phase is substantially longer than the systolic decompression phase.Type: ApplicationFiled: May 26, 2011Publication date: September 15, 2011Inventor: Gary A. Freeman

Publication number: 20110098612Abstract: In one embodiment, the invention provides a medical method for treating a person and comprises repeatedly compressing the person's chest. While repeatedly compressing the person's chest, the method further includes repeatedly delivering a positive pressure breath to the person and extracting respiratory gases from the person's airway using a vacuum following the positive pressure breath to create an intrathoracic vacuum to lower pressures in the thorax and to enhance blood flow back to the heart.Type: ApplicationFiled: July 26, 2010Publication date: April 28, 2011Applicant: Advanced Circulatory Systems, Inc.Inventor: Keith G. Lurie

Patent number: 7837636Abstract: A transmission device transforms an alternate rotational movement of an alternately rotating element into a linear reciprocating movement. The device includes a linear reciprocating element connected to the rotating element, and a first pivoting element having a first fixed pivot point connected to the linear reciprocating element. The transmission device includes a second pivoting element connected to the first pivoting element. A ball member, which may be connected to a CPR piston, is attached to the second pivoting element. A third pivoting element having a second fixed pivot point is connected to the second pivoting element.Type: GrantFiled: October 23, 2006Date of Patent: November 23, 2010Assignee: Laerdal Medical ASInventors: Øyvind Tjølsen, Viggo Lauritz Norum, Karl Patrik Mandelin

Patent number: 7806118Abstract: A cardiopulmonary resuscitation device that combines ventilation of a patient's lungs with chest compressions on the patient's sternum area. The device includes a self-inflating bag having an outlet port through which the content of the bag is forced when bag is compressed; target indicia on the bag to indicate the proper position of the bag on the patient's sternum area and to indicate the proper location on the bag for applying force to the top side thereof; a face mask for placement over the patient's mouth and nose; and a tube extending from the bag to the face mask. The device may include indicia for indicating the amount of pressure applied to the self-inflating bag, and a backboard including belt/motor structure for providing repeated and rapid chest compression and forced ventilation of the patient's lungs.Type: GrantFiled: January 6, 2006Date of Patent: October 5, 2010Inventors: Darrell K. Thompson, Phyllis D. Thompson

Patent number: 7785280Abstract: An apparatus for high frequency chest wall oscillation (HFCWO) comprises a patient interface which includes an expandable air chamber and an air pulse generator in fluid communication with the patient interface. The air pulse generator includes a variable displacement air chamber and programmable controller which controls the air pulse generator to vary the frequency and volume of air pulses delivered to the patient interface such that HFCWO therapy may be programmed for a particular patient.Type: GrantFiled: October 9, 2006Date of Patent: August 31, 2010Assignee: Hill-Rom Services, Inc.Inventor: John A. Kivisto

Publication number: 20100113990Abstract: A pneumatic device for cardiopulmonary resuscitation assist includes a back plate and a compressing member. The back plate has two securing members mounted respectively on two sides of the back plate. The compressing member includes a mounting plate and a bladder. The mounting plate is detachably connected to the back plate and has an upper surface, a lower surface, a gas passage and two securing straps. The gas passage is formed on the upper surface of the mounting plate. The securing straps are respectively mounted on two sides of the mounting plate and respectively connected selectively to the securing members. The bladder is mounted on the lower surface of the mounting plate and communicates with the gas passage. The bladder can compress a patient's chest continuously and stably when repeatedly inflating the bladder, and this provides a good cardiac massage and prevents hurting the patient's ribs.Type: ApplicationFiled: November 3, 2008Publication date: May 6, 2010Inventor: Ti-Li CHANG

Publication number: 20090306556Abstract: A chest compression system and method of use for respiratory therapies such as cystic fibrosis, including an air flow generator, a pulse frequency control component having a fan blade for producing a series of air pulses communicated to a patient-worn garment during a therapy session. The system further includes one or more patient physiologic sensors capable of capturing patient information during the therapy session. The sensors may include a blood oximeter or a mouthpiece used to evaluate pulmonary function. An airway congestion monitoring system provides airway and lung congestion trend analysis. Adjustments are made to the series of air pulses based on a patient's therapy session data.Type: ApplicationFiled: June 10, 2009Publication date: December 10, 2009Inventors: Leland G. Hansen, Greg White

Patent number: 7618383Abstract: A chest brace and method of using same that prevents the chest wall from buckling inwards during patient breathing by providing a distending force on the patient's thorax. The chest brace also restores the normal anterior-to-posterior chest dimensions by providing a distending force in this direction. The chest brace includes an anterior member adapted to overly a patient's chest. An adhesive mechanism secures the anterior member to a surface of such a patient. A support structure is coupled to the anterior member such that, in use, the support structure imparts a force on the anterior member in a manner so as to distend a thorax of such a patient.Type: GrantFiled: October 15, 2007Date of Patent: November 17, 2009Assignees: The Penn State Research Foundation, Respironics, Inc.Inventors: Charles Palmer, Jerome Matula, Jr., Lance Busch, Eugene N.
