  • Publication number: 20140058344
    Abstract: An integrated system for assessing wound exudates from the wound of a patient is described. The system may contain functionality to detect, process and report various wound parameters. The system also may make treatment determinations based on these findings. The system may detect one or more physiological values of the wound exudates from the wound of the patient. The system may means for comparing the one or more detected physiological values to predetermined physiological values in order to obtain a comparison result in real time. The system may include a processor 15 which provides an electronic signal based on a comparison result in which the electronic signal may correspond to guidelines for treating the wound 13. The system may be integrated with other wound treatment devices, such as negative pressure wound therapy devices (NPWT) 9.

  • Publication number: 20140052063
    Abstract: The body has a fluid inlet port for receiving pressurized fluid and a fluid outlet port connected to the retention balloon. A first passage connects the fluid inlet port and the fluid outlet port. A second passage in the body is connected to the balloon fluid return path and is at the pressure of the retention balloon. A valve prevents fluid flow through the first passage when actuated. The valve includes a pressure-responsive member movable to a position to obstruct fluid flow in response to fluid pressure in the second passage exceeding the predetermined level. Flexible means such as a membrane defines a normally open portion of the first fluid passage, which is closed by the moveable means bearing on the membrane when pressure exceeding the predetermined level actuates the valve.

  • Publication number: 20130304006
    Abstract: A stand-alone system for assessing wound exudates from the wound of a patient is described. The system contains functionality to detect, process and report various wound parameters. The system also may make treatment determinations based on these findings. The system may detect one or more physiological values of the wound exudates from the wound of the patient. The system may also compare detected physiological values to predetermined physiological values, in order to obtain a comparison result in real time. The system may include a processor (15) which provides an electronic signal based on the comparison result in which the electronic signal may corresponds to guidelines for treating the wound (3). The system described may be an accessory, which may be used on its own, or in conjunction with other wound treatment devices (9).

  • Publication number: 20130304007
    Abstract: An apparatus (10) for controlling flow of fluid from a wound site of a patient may include a chamber (28) connectable to a wound site and a reservoir (16). The chamber (28) may have a first deformed state, and a second state in which it is not deformed or less deformed than in the first state. The chamber (28) may be adapted to manage fluid flow between the wound site and the reservoir (16) during transition of the chamber (28) between the first state and the second state. An actuator element (64) of the apparatus (10) may be adapted to operate on the chamber (28) to transition the chamber (28) from the second state to the first state.

  • Publication number: 20130296762
    Abstract: A self-sealing dressing (10) for application to skin of a human may include a substrate (12) including elastomeric material, and a cold flow adhesive layer (18) coupled to the substrate. The adhesive layer (18) may be adapted to adhere to skin of a human to form a substantially gas impermeable seal between the adhesive layer (18) and the skin that is maintained during repeated flexure and/or extension of the dressing. A maximum thickness of the combination of the substrate (12) and the adhesive layer (18) may be about 25 um.

  • Publication number: 20130217649
    Abstract: A wound dressing having anti-microbial activity comprises a first fibre capable of bonding with silver (1) cations. The wound dressing comprises a blend of the first fibre to which silver (1) cations are bonded and a second fibre which is substantially free from silver. The wound dressing comprises from 0.01 to 5.0 percent by weight of silver (1) cations, based on the weight of fibre.

  • Patent number: 8500707
    Abstract: A drainable ostomy pouch includes a collection portion and a drain chute extending from the collection portion having a discharge opening for permitting emptying of contents from the pouch. The drain chute is foldable between an open condition in which the drain chute is extended from the collection portion, and a closed condition in which the drain chute is folded towards the collection portion; and a pocket for receiving at least a portion of the drain chute when the drain chute is in its closed condition.

  • Publication number: 20130152309
    Abstract: An antibacterial wound dressing is based on or derived from gel-forming fibres such as carboxymethyl cellulose or alginate fibres having silver ions linked thereto at some but not all of the exchangeable sites such that the distribution of silver ions over the exchangeable sites is substantially uniform. The silvered fibres for the wound dressing can be prepared by contacting an assembly of precursor gel-forming fibres having exchangeable sites under conditions which do not cause irreversible gelling of the fibres with an amount of a solution containing silver ions so as to link silver ions at some but not all of the exchangeable sites, the whole of the assembly of precursor gel-forming fibres being contacted essentially simultaneously with the entire solution containing silver ions.

  • Patent number: 8439883
    Abstract: The ostomy system includes a pouch that is adhesively coupled to a mounting wafer. The mounting wafer has a landing zone film formed of releasable plastic and the pouch has a face plate with a resealable adhesive that secures to the landing zone of the mounting wafer. The landing zone of the mounting wafer includes one portion that is immovable with respect to the body surface that the mounting wafer is secured to and another portion that is deflectable away from the body surface. The deflectable portion of the landing zone, also referred to as the floating landing zone, is sized for gripping between the fingers during pouch separation from the mounting wafer. Gripping of the floating landing zone during pouch separation helps isolate the pouch separation force from the abdominal area underlying the mounting wafer. The mounting wafer also includes indicia border lines that facilitate alignment of the pouch face plate with the mounting wafer.

  • Patent number: 8388586
    Abstract: An ostomy appliance is disclosed with an inflatable seal for sealing against the stoma. The inflatable seal has a first inflatable chamber portion for fitting inside the stoma to seal against the internal tissue. The inflatable seal also has a second inflatable chamber portion for sealing externally against the stoma and peristomal skin. In one embodiment, a tube extends through the inflatable seal to provide a communication passage for discharge of body waste without removing the inflatable seal. The tube floats with respect to an adhesive mounting member to allow a waist between the first and second inflatable chamber portions to self-locate in the stoma.

  • Patent number: 8382732
    Abstract: An ostomy coupling is disclosed comprising a floatable coupling part. The coupling part is supported with respect to an adhesive wafer by means of a flexible support collar that permits displacement of the coupling part in a floatable manner. The flexible collar comprises plastics film and has bistable shapes. The collar is configured to hold the coupling part stably in (i) an extended position spaced from the adhesive wafer, to facilitate an ostomate to manually brace the coupling part in order to relieve the attachment force when an ostomy appliance is press fitted to the coupling part, and (ii) in a retracted position close to the adhesive wafer.

  • Patent number: 8366695
    Abstract: An adapter is disclosed for an ostomy coupling. The adapter provides a floatable coupling characteristic to an ostomy body fitment that has a non-floatable coupling part. The adapter comprises a first coupling part for attaching to the non-floating coupling part of the body fitment, a second coupling part for releasably attaching to an ostomy appliance, and a flexible collar between the first and second coupling parts. The flexible collar permits the second coupling part to be displaced away from the first coupling part, thereby creating a space for an ostomate to manually brace the second coupling part against an attachment force when an appliance is fitted.
