Systems, apparatuses, and methods for providing negative pressure and/or instillation fluids to a tissue site are disclosed. Some embodiments are illustrative of an apparatus or system for delivering negative-pressure and/or therapeutic solution of fluids to a tissue site, which can be used in conjunction with sensing properties of fluids extracted from a tissue site and/or instilled at a tissue site. For example, an apparatus may comprise a dressing interface or connector that includes a pH sensor, a humidity sensor, a temperature sensor and/or a pressure sensor embodied on a single pad within the connector and proximate the tissue site to provide data indicative of acidity, humidity, temperature and pressure. Such apparatus may further comprise an ambient port for providing the pressure sensor and the humidity sensor with access to the ambient environment providing readings relative to the atmospheric pressure and humidity.

An apparatus and method for the controlled acceleration, and/or retardation of the body's inflammatory response comprises a foam pad for insertion into a wound site, a drape covering the foam pad, and a thermal control element configured to be placed proximate the wound site. The foam pad is placed in fluid communication with a vacuum source for promotion of the controlled acceleration or retardation of the body's inflammatory response. The thermal control element has a pair of flexible sheets for receiving a thermally conductive fluid.

A negative pressure therapy system is provided for inducing negative pressure in a portion of a urinary tract, the system including: (a) at least one ureteral catheter configured to be positioned within a ureter and/or kidney; (b) one or more sensor(s) configured to determine information about at least one of blood composition, blood flow, respiration, heart rate, glucose, protein, or creatinine; and (c) a controller configured to increase urine production by adjusting one or more operating parameters of a negative pressure source for inducing negative pressure through the at least one ureteral catheter into the urinary tract, based at least in part upon the information determined by the one or more sensor(s).

The present disclosure belongs to the field of treatment devices, and specifically relates to a medicated thread drainage treatment device. The treatment device includes a first treatment unit used for postoperative pain relief and drainage; a second treatment unit used for promoting quick healing of a wound; a third treatment unit used for preventing deep venous thrombosis; and an electropneumatic, negative-pressure, electric stimulation multipurpose therapy apparatus connected with the first treatment unit, the second treatment unit, and the third treatment unit and providing electropneumatic pressure, negative pressure, and electric energy. The present disclosure is used for postoperative quick healing and recovery; promotion of clinical use guidelines will greatly reduce and even eliminate the postoperative complications, particularly postoperative complications of pulmonary embolism, thus saving patients' lives.

Provided herein are rapid and effective local infection therapy methods, systems, and devices that significantly reduce the mortality, morbidity, and the cost of care in rare musculoskeletal infections. Continuous delivery of antibiotic therapy locally, at the infection site, reduces edema and provides antibiotic irrigation, significantly improving outcomes while reducing the need for systemic antibiotics.

Assemblies, systems, and methods convey fluid from an internal wound site or body cavity by applying negative pressure from a source outside the internal wound site or body cavity through a wound drain assembly that is placed directly inside the internal wound site or body cavity.

Dressings and kits for use in negative-pressure therapy are provided herein comprising one or more manifolds and a polymer film laminated to the one or more manifolds. At least one manifold is felted and the manifolds may be placed in a stacked configuration and differentially collapse under negative pressure. Methods of making and using the dressings are also provided herein.

Disclosed herein are systems and methods for providing reduced or negative pressure, and more particularly cyclical reduced pressure, to treat a wound. The system can include a wound dressing, a fluid collection container, a suction source, filters, and conduits. In addition, the system can include a control device and sensors. The sensors may be configured to monitor certain physiological conditions of a patient such as temperature, pressure, blood flow, blood oxygen saturation, pulse, cardiac cycle, and the like. Application of cyclical reduced pressure between two or more values below atmospheric pressure may be synchronized with the physiological conditions monitored by the sensors. Certain embodiments of the system utilize an air reservoir and one or more valves and pressure sensors or gauges to allow for rapid cycling of the level of reduced pressure within the wound dressing between two or more reduced pressure values.

Embodiments of negative pressure wound therapy systems, apparatuses, and methods for operating the systems and apparatuses are disclosed. In some embodiments, the apparatus includes a negative pressure source, a connector port, at least one switch, and a controller. The negative pressure source is connected through the connector port to either (i) a wound dressing having a canister configured to store fluid aspirated from the wound or (ii) a wound dressing without a canister between the connector port and the wound dressing. The controller determines, based on a signal received from the at least one switch, whether the canister is positioned in the fluid flow path and adjusts one or more operational parameters of negative pressure wound therapy based on the determination. The switch is activated by the connection of either the canister or canisterless wound dressing to the apparatus.

Embodiments of negative pressure wound therapy systems and methods for operating the systems are disclosed. In one embodiment, a negative pressure source can provide negative pressure via a fluid flow path to a wound dressing comprising a stabilizing structure. The stabilizing structure can be inserted into a wound and collapse upon application of negative pressure to the wound when the stabilizing structure is positioned in the wound. A controller can in turn determine a measure of collapse of the stabilizing structure from a pressure in the fluid flow path while the negative pressure source maintains a magnitude of the pressure in the fluid flow path within a negative pressure range. The controller can output an indication responsive to the measure of collapse.
