Patent number: 5845636Abstract: An apparatus and method for facilitating the respiration of a patient are disclosed which are particularly useful in treating mixed and obstructive sleep apnea and certain cardiovascular conditions, among others, by increasing nasal air pressure delivered to the patient's respiratory passages just prior to inhalation and by subsequently decreasing the pressure to ease exhalation effort. The preferred apparatus includes a patient-coupled gas delivery device for pressurizing the patient's nasal passages at a controllable pressure, and a controller coupled with the delivery device having a pressure transducer for monitoring the nasal pressure and a microcontroller for selectively controlling the nasal pressure. In operation, the controller determines a point in the patient breathing cycle just prior to inhalation and initiates an increase in nasal pressure at that point in order to stimulate normal inhalation, and subsequently lowers the nasal pressure to ease exhalation efforts.Type: GrantFiled: August 16, 1996Date of Patent: December 8, 1998Assignee: Puritan Bennett CorporationInventors: Roger A. Gruenke, Russell L. Trimble

Inspiratory airway pressure system controlled by the detection and analysis of patient airway sounds
Patent number: 5259373Abstract: An apparatus and method for facilitating the respiration of a patient detects patient airway sounds and resolves these sounds into audio component bands whereupon an analysis is performed to produce a trend value. In response, a pressure action is determined using the trend value for controlling the pressure delivered to a patient for preventing the onset of obstructive apnea.Type: GrantFiled: April 9, 1992Date of Patent: November 9, 1993Assignee: Puritan-Bennett CorporationInventors: Roger A.

Patent number: 4938212Abstract: A reliable, pulse-flow supplemental oxygen apparatus for alleviating respiratory ailments is provided which yields substantial savings in oxygen while giving the patient the physiological equivalent of a prescribed continuous stream of oxygen. The apparatus preferably includes a demand oxygen valve operated in a pulse mode by means of electronic control circuitry which, through an appropriate sensor, monitors the patient's breathing efforts and gives a variable "custom tailored" pulse volume of oxygen to the patient during the very initial stages of each inspiration.Type: GrantFiled: October 16, 1987Date of Patent: July 3, 1990Assignee: Puritan-Bennett CorporationInventors: James A. Snook, Thomas W. Nelson, Marilyn S. Wyble, Russell L. Trimble

The apparatus preferably includes a demand oxygen valve operated in a pulse mode by means of electronic control circuitry which, through an appropriate sensor, monitors the patient's breathing efforts and gives a variable "custom tailored" pulse volume of oxygen to the patient during the very initial stages of each inspiration. Pulse volume variability is based upon a measured parameter characterizing at least a part of one and preferably a plurality of the patient's preceding breaths; advantageously, the elapsed time interval of the patient's three preceding breath cycles is measured to effectively measure breath rate.Type: GrantFiled: October 16, 1987Date of Patent: June 12, 1990Assignee: Puritan-Bennett CorporationInventors: James A. Snook, Thomas W. Nelson, Marilyn S. Wyble, Russell L. Trimble

Patent number: 4782832Abstract: An improved nasal puff assembly is provided which is of particular benefit in the treatment of obstructive sleep apnea and which is characterized by a gas-delivery puff which fits only in the nose of the patient and is therefore of relatively small size and can be comfortably worn. The nasal puff of the invention advantageously includes a plenum chamber having an inlet and a pair of laterally spaced outlets; a pair of soft synthetic resin nares elements or pillows are operatively coupled with the spaced plenum outlets and are designed for ready adjustability so that the effective positions thereof can be altered individually for permitting custom fitting of the nares elements with respect to the nares of different patients. In this way a relatively small number of different sizes of nasal puff can be modified to meet the needs of virtually all patients.Type: GrantFiled: July 30, 1987Date of Patent: November 8, 1988Assignee: Puritan-Bennett CorporationInventors: Russell L. Trimble, Roger J. Dolida, Frederick R. Rose, Philip M. Metzler

Patent number: 4695954Abstract: A system, apparatus and method for dispsensing medications prescribed by a doctor or other medical personnel. A portable memory device (such as a magnetic card) is used to store data representing prescription information. Prescription information is encoded into the memory device by a programming device located in a pharmacy. A container having a plurality of individual compartments is filled at the pharmacy with medications in accordance with the prescription information. The portable memory device and filled container are transported together to a medication dispenser located near a patient. The dispenser includes apparatus which reads the prescription information from the memory device and makes medications within the individual compartments available to the patient only at prescribed times. The medication dispenser also includes apparatus for monitoring whether or not the patient is complying with the prescribed medication schedule. Patient compliance information is stored within the memory device.Type: GrantFiled: October 31, 1984Date of Patent: September 22, 1987Inventors: Robert J. Rose, Russell L. Trimble
