Abstract
Embodiments of negative pressure wound therapy systems and methods are disclosed. In some embodiments, an apparatus includes a housing enclosing a source of negative pressure and a controller configured to operate the source of negative pressure to provide negative pressure wound therapy to a wound. The housing can also include a communications controller configured to wirelessly transmit and receive data using a communications antenna positioned on an antenna board. The antenna board can be mounted to a communications board that include the communications controller. The antenna board can be electrically connected to the communications board via a single connector on the communications board. The antenna's ground plane can be positioned on the communications board.
Core Innovation
The invention provides an apparatus for applying negative pressure to a wound using a housing that supports a negative pressure source and electronic control circuitry. The negative pressure source provides negative pressure via a fluid flow path to a wound covered by a wound dressing, and provides negative pressure in accordance with a set of negative pressure wound therapy parameters comprising a negative pressure set point. The electronic control circuitry causes the negative pressure source to provide negative pressure at the negative pressure set point.
The apparatus further includes communications circuitry supported by the housing, controlled by the electronic control circuitry, and configured to transmit first data and receive second data via an antenna. The first data comprises at least one of a location of the housing, one or more logs corresponding to provision of negative pressure, or one or more alarms caused by provision of negative pressure. The second data comprises at least one of data for tracking the location of the housing, data for adjusting the set of negative pressure wound therapy parameters, or data for upgrading software or firmware.
The communications and antenna circuitry are implemented as first and second printed circuit boards that cooperate to form a wireless antenna. The first printed circuit board includes a ground area, while the second printed circuit board includes a conductive area configured to radiate electromagnetic waves, and the conductive area and the ground area together form the antenna configured to wirelessly transmit the first data and receive the second data.
Claims Coverage
Two independent claims are identified: one directed to an apparatus for applying negative pressure to a wound and one directed to an apparatus for treating a wound. Across these independent claims, the inventive features include negative pressure wound therapy controlled at a set point and a wireless communications system in which first and second printed circuit boards with a conductive area and a ground area together form an antenna for bidirectional wireless exchange of therapy-related data and update/adjustment data.
Negative pressure source at a negative pressure set point
A negative pressure source supported by the housing and configured to provide negative pressure via a fluid flow path to a wound covered by a wound dressing, the negative pressure source configured to provide negative pressure in accordance with a set of negative pressure wound therapy parameters comprising a negative pressure set point; electronic control circuitry configured to cause the negative pressure source to provide negative pressure to the wound at the negative pressure set point.
Bidirectional wireless communications for therapy data and updates
Communications circuitry supported by the housing and controlled by the electronic control circuitry, configured to transmit first data via an antenna comprising at least one of a location of the housing, one or more logs corresponding to provision of negative pressure, or one or more alarms corresponding to provision of negative pressure, and receive second data via the antenna comprising at least one of data for tracking the location of the housing, data for adjusting the set of negative pressure wound therapy parameters, or data for upgrading software or firmware.
A two-board antenna formed by conductive area and ground area
Antenna circuitry supported by the housing comprising a second printed circuit board electrically connected to a first printed circuit board, the second printed circuit board including a conductive area configured to radiate electromagnetic waves, wherein the conductive area and the ground area together form the antenna configured to wirelessly transmit the first data and receive the second data.
Dressing over the wound in a treatment apparatus
The apparatus for treating a wound further comprises a dressing configured to be placed over a wound.
The independent claims cover a negative pressure wound therapy apparatus with electronic control operating at a negative pressure set point, paired with wireless communications in which bidirectional first and second data are transmitted and received via an antenna formed by a conductive area and a ground area on electrically connected printed circuit boards.
