Publication number: 20230340958Abstract: A system for noise and vibration management of a smoke evacuation system includes a pump that compresses air and produces a pressure differential within an airflow path. The pump may be a sealed, positive displacement pump. The system includes vibration absorption mechanisms disposed between inner and outer housings, as well as on the outside surface of the outer housing. Methods of controlling and regulating a motor of the system to preserve the lifespan of the motor and maintain consistent airflow rates throughout the smoke evacuation system include varying a supply of electrical current to the motor so that it can operate at variable performance levels. Orifices are opened and closed in order to relieve resistance pressures within the airflow path due to clogging and blockages.Type: ApplicationFiled: July 3, 2023Publication date: October 26, 2023Inventors: Chad S. Frampton, Shawn K. Horner, Darcy W. Greep, Frederick Shelton, Jason Harris, David Yates, Roger Millis

Patent number: 11617611Abstract: An electrosurgical instrument has dual zone smoke evacuation for providing efficient capture and evacuation of smoke generated during an electrosurgical procedure. A hand piece with a proximal and a distal end is coupled to a front piece having a distal opening leading into an interior conduit. An extendable section is at least partially disposed within the interior conduit and extends distally out of the distal opening of the front piece. The extendable section is selectively translatable within the interior conduit. A negative pressure source enables the capture and evacuation of smoke through both the extendable section and the interior conduit.Type: GrantFiled: May 18, 2017Date of Patent: April 4, 2023Assignee: Megadayne Medical Products, Inc.Inventors: Darcy W.

Patent number: 11446416Abstract: Embodiments of the present invention relate to the field of pressurized fluid delivery devices for use in medical procedures. In particular, a fluid delivery pump comprises at least one compressive member configured to apply a force to a fluid reservoir. The at least one compressive member is associated with a flexible envelope, such that the flexible envelope may move the compressive member. The flexible envelope may be substantially air-tight so that it may be pressurized. When a negative pressure is created inside the flexible envelope, the flexible envelope may change volume, applying a force to the at least one compressive member. The at least one compressive member may then apply a force to the fluid reservoir and the fluid is forced out of the reservoir.Type: GrantFiled: November 13, 2019Date of Patent: September 20, 2022Assignee: Megadyne Medical Products, Inc.Inventors: Paul R. Borgmeier, Darcy W. Greep, Shawn K. Horner, Chad S. Frampton

Patent number: 11446078Abstract: A portable, battery powered electrosurgical wave generator is usable in performing electrically driven medical procedures. The wave generator can be small and lightweight to enable a user to carry and use the wave generator in non-operating room type settings. The wave generator can include a control unit that generates output signals in each of a cutting mode, coagulation mode, and a bipolar mode. The control unit can use a single circuit structure to generate the output signals for the cutting, coagulation, and bipolar modes. The output signals can be generated solely from a voltage produced by an incorporated battery within the generator.Type: GrantFiled: July 18, 2016Date of Patent: September 20, 2022Assignee: Megadyne Medical Products, Inc.Inventors: Roger Millis, Ryan D.

Patent number: 11389225Abstract: A radio frequency (RF) current sensor for remotely activating a smoke evacuation device in an electrosurgical system includes a sensor body with a cable interfacing sidewall and a retaining member. The cable interfacing sidewall and the retaining member define a retention pocket for receiving a cable communicating RF current. The RF current sensor additionally includes a sensor element for detecting RF current in the cable and a sensor cable in electrical communication with the sensor element. The RF current sensor can operate in at least two modes, depending on whether the cable communicates RF current to a monopolar or bipolar electrosurgical instrument, but regardless of the operation mode, the sensor cable can communicate an activation signal and a current signal derived from the detected RF current to the smoke evacuation device, which activates or adjusts the period of time and/or the smoke evacuation flow rate of a vacuum source.Type: GrantFiled: November 29, 2017Date of Patent: July 19, 2022Assignee: Megadyne Medical Products, Inc.Inventors: Chad S.

Patent number: 11305223Abstract: A fluid trap for minimizing the escape of contaminated fluids from the fluid trap when an orientation of the fluid trap changes during removal or transport includes a front cover, a rear cover coupled to the front cover, and an interior chamber defined by the front and rear covers. The front cover defines an inlet port extending a first distance into an interior chamber of the fluid trap. The rear cover defines an exhaust port extending a second distance away from the rear cover of the fluid trap and positioned above the inlet port when the fluid trap is in an upright position. The interior chamber has a maximum fluid volume defined as the lesser of a fluid reservoir volume, a front cover volume, and a rear cover volume.Type: GrantFiled: July 23, 2020Date of Patent: April 19, 2022Assignee: Megadyne Medical Products, Inc.Inventors: Shawn K.

Patent number: 11141577Abstract: A universal fluid system connector creates an airtight seal between a variety of smoke evacuation system receptacles and various hoses. The universal connector includes a body, a seal having a plurality of radially extending flexible fins, and a swivel. A plurality of fins on the seal are disposed along the length of the body with the outer edges of the fins forming a frustoconical shape. The fins also include one or more flexion zones of various stiffness and one or more flexible fin extensions. The fins deform against the inner wall of a receptacle and form an airtight friction fit between the universal connector and the receptacle, regardless of the taper angle, size, threads, or other features of the receptacle.

Publication number: 20210077753Abstract: A method of using a nebulizer includes connecting a medicine vial containing a medicine solution to the nebulizer and reading a medicine conductivity and/or pH value from the medicine vial. The conductivity and/or pH of the medicine solution is measured and compared with the medicine conductivity and/or pH value. When the medicine conductivity and/or pH value and the measured conductivity and/or pH of the medicine solution match, the flow rate value and dosage timings are read from the medicine vial; and the mesh is activated at the medicine flow rate value to produce a plume of particles of a medicine solution at the beginning of an inhalation. The active mesh is deactivated to stop making particles by manually or at a calculated time. The activation of the active mesh is restricted to approved users by means of an authentication code or biometric feature information.Type: ApplicationFiled: November 20, 2020Publication date: March 18, 2021Inventors: Donald M.
