An apparatus for treating a tissue site comprising a negative-pressure source configured to be fluidly coupled to the tissue site; an instillation source configured to be fluidly coupled to the tissue site; and a controller operatively coupled to the negative-pressure source and to the instillation source. The controller can be configured to operate the negative-pressure source and the instillation source to intermittently deliver negative pressure to the tissue site for a negative-pressure interval and deliver instillation fluid to the tissue site for an instillation interval. A purge volume of instillation fluid may be delivered to the tissue site at a purge frequency. In some examples, the purge volume may be delivered through the second fluid conductor and removed through the first fluid conductor during a negative-pressure interval.

The present invention relates to apparatuses and methods for treating a wound by applying reduced or negative pressure to the wound. The apparatus can include a wound cover, a fluid collection container, a vacuum pump, an inflation pump, and one or more conduits. The wound cover can be configured to move between at least a relatively rigid, generally raised position and a relatively flexible, generally collapsed position according to a predetermined program or in response to input from a user or one or more sensors. In some embodiments, the wound cover can be configured to move between at least the relatively rigid, generally raised position and the relatively flexible, generally collapsed position by adjusting the air pressure in one or more channels in the wound cover or by adjusting the length of piezoelectric or other length changing material supported by the wound cover.

The invention relates to a wound care arrangement comprising a covering unit that can be fixed on the skin surrounding a wound and that serves for producing a closed wound space comprising the wound, and a suction connection via which a vacuum can be produced in the wound space, wherein the covering unit is penneable to water vapor at least in sections.

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.

A dressing may comprise a manifold having a first planar surface and a second planar surface opposite the first planar surface, and a first layer adjacent to the first planar surface and a second layer adjacent to the second planar surface. The first layer and the second layer may be laminated to the first planar surface and the second planar surface, respectively. Pressure-responsive fluid restrictions through at least one of the first layer and the second layer may be adjacent to the manifold. The first layer and the second layer may also form a sleeve or an envelope around the manifold in some embodiments. At least one of the first layer and the second layer may be configured to be disposed between the manifold and a tissue site in use. In some examples, the dressing may have a smooth or matte surface configured to contact a tissue site.

The present invention provides devices and methods for creating and/or maintaining patency of the upper airway passage. The device is configured to fit under the chin of a subject at an external location corresponding approximately with the subject's internal soft tissue associated with the neck's anterior triangle. The device includes structural elements designed to optimize comfort, compliance and seal achieved through minimizing the pressure variation along the contact surface of the therapy device.

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.

An apparatus for negative-pressure treatment may include an enclosure having a variable volume, a port and an actuation surface, a first one-way valve configured to allow fluid ingress to the enclosure, a second one-way valve configured to allow fluid egress from the enclosure, and an actuator configured to apply a linear force to the actuation surface.

A dressing system for cooling skin or a wound site on a subject comprises a dressing having a reservoir for holding a liquid. The dressing may be configured for placement proximate to a postoperative surgical wound site of the subject or on the facial area of the subject. The dressing system includes a cooling chamber external to the dressing configured to cool the liquid. The dressing system includes a pump configured to circulate the liquid between the cooling chamber and the reservoir. The dressing system may include a suction element for applying suction at, or proximate to, the dressing for removing sweat or wound drainage.

A curable composition for use in wound care comprising, apportioned between at least one Part A and at least one Part B: one or more alkenyl-group containing polymers (i) having at least one alkenyl group or moiety per molecule, one or more SiH-containing polymers (ii) having at least one Si—H unit per molecule; and a catalyst (iii) for curing by addition of alkenyl-containing polymer (i) to SiH-containing polymer (ii), Part A and Part B independently having viscosity at 23° C. in the range 5-300 Pa.Math.s, preferably 10-100 Pa.Math.s, at a shearing rate of 10 s.sup.−1, and when combined in one Part having cure time at 23° C. in the range from 0.5 min to 25 min, wherein when dispensed into a location about a wound dressing, said wound dressing overlying a wound site and skin thereabout, said dispensing being so as to intimately contact and overlie an edge of said dressing and skin about said edge, the composition cures in contact with said edge and skin at 32° C. to an elastomer exhibiting zero or low tack at a time in the range from 0.5 to less than 30 minutes, apparatus for use with said composition comprising dispensing apparatus or wound dressing, a kit comprising the same, and methods of dispensing and curing the same and of using the same in sealing a wound dressing and in treating a wound site of a human in need thereof.
