Definitions

• the invention relates to an adhesive bandage for intravenous peripheral cannulas made of a microporous material with a recess for receiving the cannula.
• Adhesive bandages of the above type are known. They are used to fix venous catheters that are used over a long period of time and are also intended to cover the puncture site in a sterile manner and protect them against the penetration of microorganisms and prevent the occurrence of phlebitis and other complications. In the case of long-term and long-term venous catheterization, the permanent correct seating of the catheter should also be guaranteed. Adhesive bonds of this type must be permeable to sweat and oxygen and at the same time prevent the penetration of liquids.
• Adhesive bonds of this type are also intended to guarantee a firm fit of the venous catheter, to be permeable to sweat and oxygen, to prevent the penetration of microorganisms and liquids, to be skin-friendly even after a longer period of time and, moreover, to be washable and inscribable in a simple and safe manner.
• the amounts of active ingredient required are in the range from 1 to 10 mg / d, preferably from 3 to 7 mg / d; an amount in the range of 5 mg GTN / d is particularly preferred.
• the anti-inflammatory substance is preferably arranged in the adhesive dressing near the puncture site.
• the anti-inflammatory substance can also be arranged over the entire area of the adhesive bond or at several individual locations.
• the anti-inflammatory substance is preferably applied to the skin-side material of the adhesive dressing or is present on or in a carrier arranged on the inside; however, it can also be contained in the material of the adhesive dressing itself if the controlled release to the skin is guaranteed. Measures to control the delivery rate of the transdermally active substance are known to the person skilled in the art. If necessary, the anti-inflammatory substance is protected against external penetration by a barrier layer, such as an impermeable film used for this purpose.
• the adhesive dressing according to the invention is suitable for all forms of conventional cannulas for intravenous peripheral use, for example for butterfly or winged cannulas, but also for wingless cannulas and for cannulas with injection valves.
• Common sweat and oxygen-permeable materials serve as the material for the adhesive dressing, which reliably cover the puncture site and protect against the penetration of microorganisms and liquids.
• Hypoallergic microporous films are particularly suitable for this purpose, for example based on urethane or based on polymeric fluorinated hydrocarbons.
• the adhesive bandage according to the invention preferably contains in its central area, ie above the puncture site of the cannula, a transparent field or window made of a material which is customary for this, for example OpSite, through which the puncture site can be checked at any time.
• a transparent field or window made of a material which is customary for this, for example OpSite, through which the puncture site can be checked at any time.
• the cutout in the adhesive dressing for example in the form of a U-shaped incision, makes it easier to fix conventional wing cannulas by pushing the two side wings under the adhesive dressing parts adjacent to the cutout.
• the adhesive dressing in the area of this recess is provided with a holder for wingless casings. equipped.
• This holder has the form of adhesive strips which sandwich the inserted cannula at the top and bottom and fix it to the sides of the microporous material delimiting the recess.
• These adhesive adhesive strips protrude from both sides of the adhesive dressing parts delimiting the cutout and are adhesively coated on mutually facing sides. They should be long enough that they can reach the opposite side of the adhesive dressing from the side of the adhesive dressing from which they originate, beyond the cannula and recess, and can be fixed there by adhesive.
• the holder ensures a firm connection of the cannula to the two sides of the adhesive dressing, which adjoin the recess.
• a pair of opposing adhesive strips is present in the region of the cutout, but two or more pairs of adhesive strips can also be present.
• FIG. 1 shows an adhesive bandage according to the invention in accordance with a preferred embodiment with a transparent window
• the cannula is inserted in the region of the recess 2 and penetrates in the region of the window 3 the skin. It is either held by wings, which are pushed under the two adjacent to the recess 2, the parts 7 of the material 1 and fixed there by adhesive, or glued to the skin via normal adhesive strips outside the adhesive band area. The corners of the adhesive bond are rounded to complicate or prevent unwanted detachment of the adhesive bond from the skin in the corners.
• the anti-inflammatory material is arranged in the area of the porous material 1 of the adhesive dressing on the underside (not visible).
• Fig. 2 shows a further embodiment of the adhesive dressing according to the invention made of the opaque microporous material 1 with the recess 2, the transparent window area 3 and an inserted cannula 4.
• the cannula 4 is in the region of the recess 2 by adhesive strips 5, 5 'which Both sides of the recess 2 project from the adjacent sides of the material 1, held in place by adhesive, a strip 5 bridging the recess 2 on one side of the cannula and the strip 5 'on the opposite side (covered in FIG. 1) , so that the cannula is sandwiched by the two strips and fixed to the adjacent sides 7 of the adhesive bond.
• the adhesive bandage has an area in the area of the window 3 in which the anti-inflammatory agent is arranged.
• the anti-inflammatory agent can also be arranged in the areas 6 'or 6' ', for example in the form of spots or supports coated with GTN, which are optionally secured by a barrier material to prevent the substance from passing through the adhesive dressing to the outside.
• the adhesive bandages according to the invention have the customary dimensions, for example approximately 75 x 120 mm with a window size of 55 x 45 mm and a recess tapering towards the center of 10 mm in initial width and 75 mm in length.
• these dimensions can vary depending on the area of application and, for example for children, can be significantly smaller.
