  • Patent number: 11504466
    Abstract: A medical gauze and gas flow assembly and method of applying a medical gauze with gas flow over a wound, provides a medical dressing cover that couples to a gas flow framing structure. The gas flow framing structure provides a flow of gas over a wound. A medical grade gauze material adheres to the lower surface of the medical dressing cover, so as to create spacing between the medical grade gauze material and the wound treatment area. The gas flow is directed between the medical grade gauze material and the wound treatment area. The gas flow vents to ambient though the gas permeable medical dressing cover. When degraded, the assembly is replaced or only the medical dressing cover and medical grade gauze material is replaced. The synergistic combination of a medical grade gauze material that is a gas permeable, with a gas flow structure that discharges gas over the wound enhances healing the wound.

  • Patent number: 11268656
    Abstract: A method for calculating the remaining usage time of a gas cylinder equipped with a pressure reducer, the method comprising the following steps: (a) measuring the pressure of the gas in the cylin-der; (b) calculating the variation of pressure of the gas in the cylinder over time while gas is out-putted; (c) calculating a remaining usage time Tr based on the measured pressure in the cylinder and the calculated variation of pressure. Step (c) takes into account characteristics of the pressure reducer relative to variations of its nominal flow rate along the decrease of its inlet pressure while emptying the cylinder.

  • Patent number: 11154682
    Abstract: A ventilation tube unit (2), for connection to a medical ventilator, includes an outer tube (4) with a tubular connection device (18) with a jacket-side branch (24, 28), for connecting a medical unit such as a water trap, arranged between a first outer tube part (20) and a second outer tube part (22). An inner line (6) is arranged within and extends with the outer tube (4) between two port connectors (8). Each outer tube part (20, 22) includes a variable-length outer tube part that can be varied between a compressed state and an expanded state. The connection device (18) is displaceable in the longitudinal direction (A) relative to the inner line (6) by a compression of one outer tube part (20) and a corresponding expansion of the other outer tube part (22). A ventilation system with at least one such ventilation tube unit is also provided.

  • Patent number: 11090458
    Abstract: The system includes an air flow generator configured to deliver an air flow at a positive therapeutic pressure during the treatment, and an expiratory valve with an open pressure connected to the air flow generator. The open pressure is dependent on the therapeutic pressure from the air flow generator. The expiratory valve further exerts a back pressure upon each exhalation from the patient sufficient to create a pneumatic splint in the patient's respiratory tract. The exhalation from the patient has a first half followed by a second half, and the back pressure is varied such that during the start of the first half, the back pressure is between 0 and 50% of a peak back pressure, and increases to a peak back pressure in the second half.

  • Patent number: 11083490
    Abstract: A system includes an access cannula, a deployment cannula having a plurality of engagement arms, and a containment bag. The deployment cannula is slidable within the access cannula between an initial condition, wherein the engagement arms are retained in a contracted configuration, and a deployed condition, wherein the engagement arms are disposed in an expanded configuration. The containment bag includes an open end portion configured to receive the first elongated tubular member and the second elongated tubular member. In the initial condition, a portion of the containment bag towards the open end portion is positioned adjacent at least one of the first elongated tubular member or the second elongated tubular member. In the deployed condition, the portion of the containment bag is expanded such that the portion of the containment bag is spaced-apart from the at least one of the first elongated tubular member or the second elongated tubular member.
