An ultra-portable therapy system for treating a tissue site with negative pressure is disclosed. In some embodiments, the therapy system may include a wound dressing, a low-profile conduit, a therapy unit, and a communications device. Some embodiments may also include aspects of a therapy network, including communications networks and a remote monitoring center.

Embodiments of apparatuses and methods for determining an emplacement of sensors in a wound dressing are disclosed. In some embodiments, a wound dressing includes a plurality of sensors configured to measure wound or patient characteristics. One or more processors are configured to receive wound or patient characteristics data as well as emplacement data. The received data can be used to determine an emplacement of the plurality of sensors, the wound dressing, or a wound. The sensors can include a set of nanosensors. The wound dressing can include pH sensitive ink which can be utilized for determining a placement of the wound dressing and determining a pH associated with the wound. The wound dressing can be used in a negative pressure wound therapy system.

A system and apparatus for the collection of serous or serosanguinous fluid from a percutaneous site after surgery. A pump unit with one or more pumps or powered sources provide continuous negative pressure suction to draw fluid from the percutaneous site and pumps the fluid into disposable reservoirs with one-way valves that are easy to handle while maintaining sterility and a seal to prevent the loss of vacuum. Air is continuously removed from the reservoirs. Measurement and analysis of the output is performed automatically. Additionally, through such a peristaltic pump device, controlled collection of measured surgical and/or bodily fluid from a subject patient may be undertaken allowing for more effective and closer analysis, as well.

Embodiments of apparatuses and methods for providing negative pressure wound therapy to multiple wounds are disclosed. In some embodiments, an apparatus includes a negative pressure source configured to couple via a plurality of fluid flow paths to a plurality of wound dressings. The plurality of flow paths includes a plurality of calibrated leaks. The apparatus also includes a controller configured to determine a total rate of flow in the plurality of fluid flow paths and compare the total rate of flow to a plurality of thresholds associated with the plurality of calibrated leaks to determine one or more operating conditions, such as a blockage in one or more of the plurality of flow paths. An indication of the operating condition can be provided.

The present disclosure generally relates to a mobile negative pressure wound therapy (NPWT) device comprising a negative pressure pump, where the NPWT device is adapted to generate an alarm signal in case of an abnormal operation of the NPWT device. The present disclosure also relates to a corresponding method for operating such anNPWT device and a thereto related computer program product.

Disclosed herein are embodiments of a wound treatment apparatus employing hydrophobic and hydrophilic dressing materials and/or coating of the layers of a wound dressing. In some embodiments, the hydrophobic and hydrophilic dressing materials and/or coating controls the migration of fluid within the wound dressing.

Embodiments of negative pressure wound therapy systems and methods are disclosed. In one embodiment, an apparatus includes a housing, a negative pressure source, a canister, an antenna, and one or more controllers. The negative pressure source can provide negative pressure via a fluid flow path to a wound dressing. The canister can be positioned in the fluid flow path and collect fluid removed from the wound dressing. The antenna can be supported by the housing and wirelessly communicate with an electronic device. The antenna can be oriented in the housing to face downward toward the ground when the negative pressure source is providing negative pressure. The one or more controllers can activate and deactivate the negative pressure source and transmit first data to the electronic device using the antenna or receive second data from the electronic device using the antenna.

A chemical pump assembly useful for negative pressure therapy includes a chemical pump housing having an inner chamber, a reactor located within the inner chamber, an opening provided in the chemical pump housing, a first pull tab which extends from the inner chamber to ambient through the opening, and a removable layer connected to the first pull tab. The reactor is configured to react with a selected gas found in air so as to consume the selected gas when exposed to air in the inner chamber. The removable layer shields the reactor from air in the inner chamber atmosphere until the removable layer is removed.

Embodiments of negative pressure wound therapy systems and methods for operating the systems are disclosed. In some embodiments, a system includes a negative pressure source, a wound dressing configured to be positioned over a wound, and optionally a canister configured to store fluid aspirated from the wound. The negative pressure source, wound dressing, and canister (when present) can be fluidically connected to facilitate delivery of negative pressure to the wound. The system can be configured to automatically detect whether the canister is positioned in the fluid flow path between the negative pressure source and the dressing while negative pressure source provides negative pressure to the wound dressing. Operation of the system can be adjusted based on whether presence of the canister has been detected. For example, a value of an operational parameter can be set to indicate that the canister is present.

A container for a portable surgical drain system to receive a fluid from a drain at a surgical site is disclosed. The container includes a drain hub having at least one sensor and a cartridge removably coupled to the drain hub in fluid communication with the drain to provide a suction source to draw and receive the fluid from the surgical site. The at least one sensor detects a characteristic of the fluid in the cartridge.
