A carrying case (500) and handle (504) for accommodating a portable topical negative pressure therapy apparatus (200) comprising a device (202) and a waste canister (204) separable therefrom, the waste canister having an aspiration conduit (274) emerging therefrom is described, the carrying bag comprising an apparatus receiving pouch (502), said pouch having opening and closing means (522, 524) at a lower portion thereof and said handle (504) being directly attached to said apparatus.

A new system for negative pressure wound therapy is described. The system includes a patient tube set connecting the wound dressing to the suction container. The patient tube set provides separate channels for applying suction to the wound site and sensing the therapeutic pressure at the wound site. A restrictor valve may also be included in order to introduce a small air leak into the system to prevent occlusions in the patient tube set.

Embodiments described herein relate to apparatuses, systems, and methods for the treatment of wounds, for example using multiple wound dressings in combination with negative pressure wound therapy. A negative pressure would therapy apparatus can include a negative pressure source and a controller. The negative pressure source can include inlets configured to couple via fluid flow paths to wound dressings. The fluid flow paths can include pressure sensors configured to measure pressure in the fluid flow paths. The pressure sensors can include a first pressure sensor configured to measure pressure in the first fluid flow path and a second pressure sensor configured to measure pressure in the second fluid flow path. The controller can be configured to operate the negative pressure source and provide, based on measured pressure, indication of at least one operating condition associated with at least one of the fluid flow paths.

A reduced pressure treatment system includes a control unit having a control system and a reduced pressure source. The reduced pressure treatment system further includes a manifold unit in fluid communication with the reduced pressure source and a component module to augment treatment. The component module is configured to communicate with the control system of the control unit, and the component module includes a first mounting region configured to be coupled to a complimentary mounting region of the control unit. The component module further includes a second mounting region identical to the complimentary mounting region of the control unit to allow a second component module to be coupled to the first component module.

Inline storage pouches and systems for receiving and retaining body fluids from an animal are presented. The inline storage pouch include a flexible pouch body has an interior portion with a fluid storage material disposed within the interior portion. In addition to receiving body fluids, the inline storage pouch may fluidly couple a pressure sensing conduit between a first port and a second port using a first bypass conduit. The first port may be a patient-port interface. The second port may be a device-port interface. Multiple sensors and bypass conduits may be included and associated with a microprocessor that is configured to locate blockages or determine when the inline storage pouch is full. Another inline storage pouch has two chambers and receives and discharges fluids from a pouch connector. Other pouches, systems, and methods are presented herein.

Embodiments of apparatuses and methods for determining a positioning of sensors in a wound dressing are disclosed. In some embodiments, a wound monitoring and/or therapy system can include a wound dressing and a plurality of sensors configured to measure one or more wound characteristics. The wound monitor system can also include at least one positioning device configured to indicate position and/or orientation in the wound of a sensor of the plurality of sensors. In some embodiments, a detector can be configured to determine, based on the positioning data, the position and/or orientation in the wound of the sensor of the plurality of sensors. In some embodiments, the plurality of sensors can be positioned on a strip or string of material in communication with the positioning device.

Embodiments of negative pressure wound therapy systems, apparatuses, and methods for operating the systems and apparatuses are disclosed. In some embodiments, a medical device is configured to detect an identity of a patient-contacting disposable connected to the medical device. The medical device automatically modifies one or more operational parameters of the medical device based on the identity of the patient-contacting disposable connected to the medical device. The medical device can include a user interface and modify automatically available selections in the user interface based on the identity of the patient-contacting disposable connected to the medical device.

Embodiments of negative pressure wound therapy apparatuses and methods for using such apparatuses are disclosed. In some embodiments, a negative pressure wound therapy apparatus includes a controller configured to determine a level of exudate in a canister (or a dressing) based at least in part on one or more characteristics of pressure signals generated by a negative pressure source and monitored by a pressure sensor. One such characteristic of the pressure signals can be amplitude, which may increase as a level of exudate in the canister (or dressing) increases. The canister (or dressing) can include a filter configured to become occluded in order to prevent overflow of the canister (or dressing). The controller can be additionally configured to detect and indicate a canister (or dressing) pre-full condition before the filter becomes occluded. More efficient and reliable operation of the negative pressure wound therapy apparatus can thereby be attained.

An apparatus for applying negative pressure to a wound is disclosed. The apparatus can include a housing, a pressure source, a canister, and a controller. The pressure source can be supported by the housing and provide negative pressure via a fluid flow path to a wound dressing positioned over a wound. The canister can collect exudate from the wound. The controller can monitor a parameter indicative of providing negative pressure to the wound dressing with the pressure source, determine from the parameter that the wound is treatable with a canisterless wound therapy apparatus, and output for presentation to a user a notification indicating that the wound is treatable with the canisterless wound therapy apparatus.

A wound therapy system and method for clearing fluids from a conduit includes a wound dressing apparatus, a pneumatic pump, a valve, and a controller. The wound dressing apparatus is fluidly coupled to a wound, the pump, and the valve. The controller is configured to determine a volume of instillation fluid that has been delivered to the wound, to operate the pneumatic pump and the valve to apply a negative pressure to the wound dressing apparatus to purge a first portion of the instillation fluid, and to operate the pneumatic pump and the valve during a purge operation to deliver a volume of air through the wound dressing apparatus that is approximately equal to or greater than the volume of instillation fluid to purge a second portion of the instillation fluid from the wound dressing apparatus.
