In the transparent wound dressing, the water absorbing layer is four layers, and the width of the strip-shaped through hole is 1.5 mm.

Aforesaid transparent wound is applied ointment or plaster, paper frame formula is from type paper constitution and is had: and the release paper frame is positioned on the writing adhesive tape on the release paper frame.

The utility model discloses an useful part lies in:

The water absorption pad of the utility model is designed to be compounded by a plurality of layers of water absorption non-woven fabrics, thereby improving the liquid absorption capacity of the application and avoiding leakage;

The utility model arranges the through holes on the water-absorbing non-woven fabric, so that the application has ductility and can be stably fixed when being used at the position of the movable joint;

The utility model discloses be rectangular shape with the shape design of through-hole, the bar through-hole of lower floor is located the position between the bar through-hole of upper strata, and liquid is avoided piling up at the through-hole position to such design for the non-woven fabrics that absorbs water can in time absorb liquid.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

A transparent wound dressing comprising: the medical water-absorbing pad comprises an extension type water-absorbing pad 1, release paper 2 arranged below the extension type water-absorbing pad 1, a medical pressure-sensitive adhesive 3 connected to the extension type water-absorbing pad 1, a polyurethane film 4 connected to the medical pressure-sensitive adhesive 3, and paper frame type release paper 5 connected to the polyurethane film 4; the extension type absorbent pad 1 comprises: the plurality of water absorbing layers are arranged on the strip-shaped through holes 101 on each water absorbing layer; preferably, the water-absorbing layer is a water-absorbing nonwoven fabric layer, and the water-absorbing layer may also be made of other water-absorbing materials such as hydrocolloid, and the material is not limited. As an example, the thickness of the water-absorbent nonwoven fabric is 0.2 to 0.5 mm.

As shown in fig. 1, the strip-shaped through holes 101 provided in the respective layers are not communicated with each other; the strip-shaped through holes 101 on the lower layer are positioned between the strip-shaped through holes 101 on the upper layer; due to the design, liquid is prevented from being accumulated at the position of the through hole, and the liquid accumulated in the through hole of the lower layer can be absorbed by the water-absorbing non-woven fabric of the upper layer; so that the water-absorbing non-woven fabric can absorb liquid in time.

The length of the strip-shaped through hole 101 is determined according to the size of the water-absorbent non-woven fabric, and the distance between the edge of the through hole and the edge of the water-absorbent non-woven fabric is 1cm-2 cm.
