Patent number: 11865254Abstract: An oscillating positive expiratory pressure apparatus having a housing defining a chamber, a chamber inlet, a chamber outlet, a deformable restrictor member positioned in an exhalation flow path between the chamber inlet and the chamber outlet, and an oscillation member disposed within the chamber. The deformable restrictor member and the oscillation member are moveable between an engaged position, where the oscillation member is in contact with the deformable restrictor member and an disengaged position, where the oscillation member is not in contact with the deformable restrictor member. The deformable restrictor member and the oscillation member move from the engaged position to the disengaged position in response to a first exhalation pressure at the chamber inlet, and move from the disengaged position to an engaged position in response to a second exhalation pressure at the chamber inlet.Type: GrantFiled: April 20, 2020Date of Patent: January 9, 2024Assignee: Trudell Medical InternationalInventors: Jerry Grychowski, Martin P. Foley

Patent number: 10716700Abstract: A nasal insert includes a housing having a circumferential wall defining an interior passage. The wall has a longitudinal gap extending along a length thereof, with an outer peripheral dimension of the housing being adjustable by varying the gap. A valve is in communication with the interior passage and limits a fluid flow through the interior passage in at least one direction. In another embodiment, a nasal insert includes a user interface having a tubular housing defining an interior cavity open at opposite ends. An exterior surface of the housing is adapted to interface with a nasal vestibule of a user. A base is received in the interior cavity of the housing and includes an exit port. A cap is connected to the base and has an input port. A valve member is disposed in an interior passage defined by at least one of the cap and base, with the valve member being moveably received in the interior passage. Methods of using and assembling the nasal inserts also are provided.Type: GrantFiled: July 20, 2017Date of Patent: July 21, 2020Assignee: Trudell Medical InternationalInventors: Martin P.

Patent number: 10709852Abstract: A delivery device includes a toroidal shaped housing defining an interior chamber and a central open space. The housing includes an input port communicating with the interior chamber and a delivery port positioned on an inner periphery of the housing. The delivery port is in fluid communication between the interior chamber and the central open space. The delivery port is spaced from the input port, which is adapted to receive an aerosolized medicament. In another aspect, a kit includes an outer ring-like housing component and a plurality of differently configured inner ring-like housing components mateable with the outer ring-like housing to form a holding chamber. A method of delivering an inhalable substance is also provided. A mask, including mounting and sealing portions is also provided, together with a method of manufacturing such a mask. Delivery devices include various alternative adapters to be used with a mask and a substance dispenser.Type: GrantFiled: September 15, 2015Date of Patent: July 14, 2020Assignee: Trudell Medical InternationalInventors: Daniel Engelbreth, Martin P.

Patent number: 10220176Abstract: Ventilator circuit aerosol delivery systems used to administer medication to a patient are disclosed. In one implementation, a metered dose inhaler (“MDI”) ventilator assembly may include a housing that defines an interior space, an inhalation port that defines an inhalation passageway in communication with the interior space, an exhalation port that defines an exhalation passageway in communication with the interior space, a patient port that defines a patient passageway in communication with the interior space, and a MDI receptacle positioned on the housing and in communication with the interior space. The MDI receptacle is operative to receive a MDI container and dispense an aerosolized medication within the MDI container into the interior space so that during inhalation, an inhalation flow including the aerosolized medication may flow through the inhalation port, the interior space, and the patient port.Type: GrantFiled: October 14, 2014Date of Patent: March 5, 2019Assignee: TRUDELL MEDICAL INTERNATIONALInventors: Martin P.
