Embodiment Construction

[0049] figure 1 a) shows a bottom view of the suction connection 10 of the wound treatment device according to the invention, figure 1 b) shows a plan view of the suction connection 10 of the wound treatment device according to the invention, figure 1 c) shows a cross-sectional view of the suction connection 10 of the wound treatment device according to the invention.

[0050] figure 1 The suction adapter 10 shown in has a flange-shaped application region 11 with a disc-shaped flat application surface 12 without protrusions. The application surface 12 is penetrated by a suction opening 14 . Furthermore, a likewise circular suction opening 14 is arranged in the central region of the application surface 12 . The suction opening 14 is connected to a connecting device 20, which is formed as a pipe joint and makes it possible to deflect the flow of exudate liquid perpendicular to the application surface 12 by 90°, so that the direction of the liquid flow after the deflection is...

Abstract

#CMT# #/CMT# The arrangement has a covering unit i.e. reciprocally open film tube, fixed on skin that surrounds a wound. The covering unit produces a closed wound space that comprises the wound. A suction connection (10) produces a vacuum in the wound space, and the covering unit is partially permeable to water vapor. The covering unit comprises a transparent covering film, where a thickness of the covering lies within a range of 1-100 micrometer. Adherent attaching units are attached to the covering unit for adherent fastening of the covering unit at the skin surrounding the wound. #CMT#USE : #/CMT# Wound care arrangement for use in vacuum therapy for healing chronic wounds at a forearm at a body of a patient. #CMT#ADVANTAGE : #/CMT# The suction connection produces the vacuum in the wound space, and the covering unit is partially permeable to the water vapor, thus enabling healing of the wounds in a reliable manner while enabling prevention of excessive drainage of the wound. The covering unit is produced in a simple manner. The arrangement enables prevention of contamination of the wound. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a rear view of a suction connection of a wound care arrangement. 10 : Suction connection 11 : Flange-shaped equipment area 20 : Pipe socket 30 : Suction hose #CMT#POLYMERS : #/CMT# The covering unit is made of polyurethane polymer i.e. aromatic polyurethane polymer.

Description

technical field [0001] The present invention relates to a wound treatment device comprising a covering device fixable to the periwound skin for forming a closed wound space containing the wound, and a suction connection through which a negative pressure is created in the wound space, the invention also relates to a device for Covering means for the wound treatment device. Background technique [0002] The aforementioned wound treatment devices are mainly used in so-called vacuum therapy procedures. The healing of chronic wounds has been found to be particularly enhanced by applying negative pressure at the wound site. It has also proven to be advantageous if the wound is covered or filled with open-cell foam or gauze as filling material and the wound is covered so that a closed wound space containing the wound and possible filling material is formed and the covering device A suction connection is provided on the side facing away from the wound or filling material, via whic...
