Connection device for use in the negative pressure therapy of wounds

The invention relates to a method for estimating a negative pressure at a wound site during a negative pressure wound therapy. The method comprises the steps of determining a negative pressure value by means of a pressure sensor, determining a pump speed associated with the electrical pump, multiplying the pump speed by a constant to obtain a modification value, and combining said modification value with the negative pressure value determined by means of the pressure sensor to obtain a modified negative pressure value. Said modified negative pressure value corresponds to the estimated negative pressure present at the wound site. The invention further relates to a negative pressure wound therapy system adapted to execute said method of estimating a negative pressure at a wound site.

Abdominal wound dressing comprising joining means

A connection device for use in the negative pressure therapy of wounds, includes a flexible conduit having at least two lumens and being constructed for impingement with negative pressure and/or fluid media; a coupling body made of an elastomeric flexible material, and non-detachably molded onto a wound-side end section of the conduit and being constructed for arrangement on a negative pressure bandage which covers the wound and seals the wound against the atmosphere, wherein the conduit communicates with a wound space through at least one opening in the coupling body; and a fluid inlet section for insertion through an opening in the negative pressure bandage into the wound space. The fluid inlet section is formed on the coupling body and protrudes over a walling of the coupling body, which walling faces the negative pressure bandage. The fluid inlet section is fluidly connected interiorly of the coupling body with a further lumen for delivering a fluid medium. The further lumen is formed inside the conduit or by a fluid delivery line leading to the coupling body.

Connection device for use in the negative pressure treatment of wounds

A connection device for use in the negative pressure therapy of wounds includes a flexible conduit which can be impinged with negative pressure and/or fluid media, the conduit having at least two lumens, a coupling body formed by an elastomeric flexible material which is non-detachably injection molded to a wound-side end section of the conduit, and being constructed for placement on a negative pressure bandage which covers and seals the wound negative pressure tight against the atmosphere, the conduit communicating through at least one opening in the coupling body with the wound space, and an end cap attached and preferably non-detachably fastened to the injection molded-on material of the coupling body, thereby sealing the coupling body tight against the outside.

The invention refers to a device for the negative pressure wound therapy comprising a cover material for the air-tight sealing of the wound and the wound surroundings; a means suitable for the generation of a negative pressure in the wound area, preferably a means for the functional connection of the wound area with a negative pressure source outside of the cover material in such a way that a negative pressure can be generated in the wound area and fluids can be drawn out of the wound area by suction; and a wound dressing, whereby the wound dressing contains an open-cell foam on the basis of a cross-linked polyorganosiloxane. The invention also refers to the use of open-cell foam on the basis of a cross-linked polyorganosiloxane for use in the negative pressure wound therapy, in particular in patients with a BMI of less than 18.
