Abstract

The utility model relates to a medical dressing field, concretely a medical PU membrane of difficult emergence deformation. The utility model provides a medical PU membrane of difficult emergence deformation, includes the protection paper layer of top layer, is provided with the PU rete in the lower part of protection paper layer, the bottom of PU rete is provided with fixed stratum reticulare, fixed stratum reticulare inlays on the PU rete, is provided with the viscose layer in the lower part of fixed stratum reticulare, is provided with fixed paper layer in the lower part of viscose layer. The fixed net layer is of a rectangular net structure, and the protective paper layer and the fixed paper layer are both made of release paper. This kind of PU membrane sets up fixed stratum reticulare, can prevent effectively that the PU membrane from dragging when using and taking place deformation to and paste together.

Description

Medical PU membrane difficult to deform

Technical Field

The utility model relates to a medical dressing field, concretely a medical PU membrane of difficult emergence deformation.

Background

The polyurethane film (PU film) has better elasticity and high lightness, has incomparable advantages on the waterproof performance though the thickness is extremely thin, is a nontoxic and harmless environment-friendly material, has no harm to the skin of a human body, and is widely applied to the field of medical treatment. Particularly, in the field of medical dressings, the PU film has obvious advantages, but because the PU film is light and extremely thin, the PU film is easy to deform when being used in the medical dressings and is easy to curl and stick together when being made into the dressings for use, and the PU film is very inconvenient to use.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome not enough among the prior art, provide a medical PU membrane that is difficult for taking place deformation, this kind of PU membrane sets up fixed stratum reticulare, can prevent effectively that the PU membrane from dragging when using and taking place deformation to and paste together.

For solving the prior art problem, the utility model discloses a medical PU membrane of difficult emergence deformation, including the protection ply at top layer, be provided with the PU rete in protection ply's lower part, the bottom of PU rete is provided with fixed stratum reticulare, fixed stratum reticulare inlays on the PU rete, is provided with the viscose layer in the lower part of fixed stratum reticulare, is provided with fixed ply in the lower part of viscose layer.

Preferably, the fixed net layer is a rectangular net structure.

Preferably, the protective paper layer and the fixed paper layer are both made of release paper.

The utility model has the advantages that: the bottom of the PU film layer is provided with a fixed net layer which can be made of cotton threads or other chemical materials harmless to the skin. The fixed net layer is of a rectangular net structure, the PU film is divided into small rectangular blocks, positioning is carried out on the small rectangular blocks, deformation cannot occur easily even if the small rectangular blocks are dragged by external force, the shape is more stable, and operation is facilitated. Set up the protection paper layer at the top layer, can play the guard action, avoid external force to damage the PU rete, set up fixed paper layer at the bottom, play the guard action on the one hand, also play the support fixed action simultaneously. The PU film can be better fixed and adhered to the skin due to the existence of the adhesive layer, and the fixed net layer is clamped between the adhesive layer and the PU film layer, so that the fixed net layer is more stable.

Detailed Description

The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

The utility model provides a medical PU membrane of difficult emergence deformation, includes the protection ply 1 of top layer, is provided with PU rete 2 in the lower part of protection ply 1, the bottom of PU rete 2 is provided with fixed stratum reticulare 3, fixed stratum reticulare 3 inlays on PU rete 2, is provided with viscose layer 4 in the lower part of fixed stratum reticulare 3, is provided with fixed ply 5 in the lower part of viscose layer 4.

The fixed net layer 3 is a rectangular net structure, and the protective paper layer 1 and the fixed paper layer 5 both adopt release paper.

The utility model has the advantages that: the bottom of the PU film layer 2 is provided with a fixed net layer 3, the fixed net layer 3 can be made of cotton thread or other chemical materials harmless to the skin. Fixed stratum reticulare 3 is the network structure of rectangle, divides the PU membrane into individual little rectangular block, carries out the effect of location to it, even if meet external force and pull, can not take place deformation easily yet, and the shape is more stable, the operation of being convenient for more. Set up protection paper layer 1 at the top layer, can play the guard action, avoid external force to damage PU rete 2, set up fixed paper layer 5 at the bottom, play the guard action on the one hand, also play the support fixed action simultaneously. The PU film can be better fixed and adhered to the skin due to the existence of the adhesive layer 4, and the fixed net layer 3 is clamped between the adhesive layer 4 and the PU film layer 2, so that the fixed net layer 3 is more stable.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
