  • Patent number: 10758856
    Abstract: A filter includes (i) a filter body, (ii) a front cap associated with a first end of the filter body and coupled to and receiving smoke from a vacuum hose, (iii) a back cap associated with a second end of the filter body and having a filter exhaust sized and shaped to associate with and communicate suction from a smoke evacuation system, (iv) a compressed carbon reservoir disposed within the filter body between the front cap and the back cap, and (v) a flexible porous barrier disposed on at least a first side of the compressed carbon reservoir. The compressed carbon reservoir is under a compressive bias by the flexible porous barrier that transitions from a flexed state to a partially relaxed state in response to the compressed carbon reservoir reducing in volume.

  • Publication number: 20200214760
    Abstract: A filter connection for a smoke evacuation device includes a filter canister assembly and a socket. The filter canister assembly has a cross-sectional shape with only one line of symmetry that corresponds to a cross-sectional shape of the socket so that the filter canister can only be inserted into the socket in one orientation. One or more key notches on the filter canister may also ensure that the filter is properly installed. A seal creates an airtight boundary between the filter canister and a recess of the socket so that a sealed path in communication with the smoke evacuation device is established before the filter canister is fully inserted into the socket. An electronic connection is made between the filter canister and the socket after the airtight boundary is created.

  • Patent number: 10670306
    Abstract: Some heat pumps have displacers mechatronically-controlled via springs and coils acting upon a ferromagnetic plate. In some prior art heat pumps, the components are housed in hot parts of the heat pump and in others, the components are housed in a cold part of the heat pump, but the components are offset from a central axis of the heat pump. A heat pump with the mechatronic driver components collinear with a central axis of the heat pump has the components in a cold part of the heat pump.

  • Patent number: 10352272
    Abstract: A thermodynamic apparatus, such as a Stirling engine or a Vuilleumier heat pump, has a heat exchanger in which energy is exchanged between a working fluid and an exhaust gas stream. On top of the cylinder of the thermodynamic apparatus is a dome-shaped section. By incorporating the heat exchanger within the dome, the flow paths can be simplified, the number of separate components reduced, and overall weight reduced. Flow passages for the working fluid are embedded in the dome. Channels for the exhaust gases are formed in an outer surface. The passages and the channels are helically arranged, one clockwise and one counter clockwise. The dome can be cast with a core for the casting fabricated via three-dimensional printing. In some embodiments, the dome is made of fiber-reinforced material.

  • Publication number: 20190162186
    Abstract: 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.

  • Publication number: 20190159825
    Abstract: 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.
