Abstract
A water-proof flexible adhesive polyurethane film for medical purpose is composed of an antisticking bottom layer with overlapped and folded central opening, a central adhesive polyurethane film, and a surficial antisticking polyethene film with a color stripping belt at its one end. Its preparing process and application are also disclosed.
Description
Technical field:
The present invention relates to a kind of Surgidressing technology, particularly disclose a kind of processing technology of polyurethane film medical flexible water-proof adhesive plaster and using method, be widely used in the little wound of human body, scratch, fixed needle and conduit when also can be used for infusing.
Background technology:
Medical polyurethane (PU) bandage belongs to disposable use medical supplies, adopts the ventilative PU base material of import, and composite skins backing base material, bottom separate paper, makes through cutting, sterilize, packing.The medical wound patch that prior art manufacturer produces, adopting has glue part both sides each minute to cut away 1cm the PU base material to be used as peeling off mouth, to reach the purpose that the bottom separate paper is peeled off.Cross cutting one place that begins to speak on the backing base material of the top layer of PU base material is to reach the purpose that top layer backing base material is peeled off.The production and processing technology complexity of this kind medical wound patch, production equipment requires very high, needs special equipment, again because 1cm has respectively been cut on the both sides of PU material, causes effective usable floor area of material to reduce, so production cost is also very high.And complicated operation has the suspicion of inconvenience when in use.
Summary of the invention:
The objective of the invention is to disclose a kind of processing technology of polyurethane film medical flexible water-proof adhesive plaster and using method, product processing of the present invention is simple, and cost reduces, and is easy to use.
The present invention is achieved in that a kind of processing technology of polyurethane film medical flexible water-proof adhesive plaster, the water-proof adhesive plaster structure is bottom separate paper, middle level gluing polyurethane film, top layer polyethylene antiadhesion barrier, it is characterized in that: described bottom separate paper middle opening, the opening part separate paper is overlapping to be amounted to; Bonding coloured stripping tape on the polyethylene antiadhesion barrier one end limit, described top layer, described coloured stripping tape is longer than the top layer antiadhesion barrier.The using method of polyurethane film medical flexible water-proof adhesive plaster, it is characterized in that: begin to peel off the bottom separate paper from the overlapping folding section of bottom separate paper middle opening, then middle level gluing polyurethane film is sticked on desired area, begin to peel off top layer polyethylene antiadhesion barrier from coloured stripping tape again; The part of being longer than the top layer antiadhesion barrier with coloured stripping tape is that handgrip is peelled off the top layer antiadhesion barrier.
The invention has the beneficial effects as follows:
1, from the production cost, product raw material availability 100% of the present invention, and prior art raw material availability 78%, the present invention greatly reduces production cost of products;
2, from production equipment, product of the present invention can be produced on common production wound equipment, and the product of prior art will be produced on special equipment, and production and processing of the present invention is simpler;
3, on using method, the product of the prior art that product of the present invention compares has and uses advantage more easily.
Description of drawings:
Fig. 1 peels off bottom separate paper sketch map when being the prior art use;
Fig. 2 peels off top layer backing base material sketch map when being the prior art use;
Fig. 3 is a product structure sketch map of the present invention;
Fig. 4 is that the present invention peels off bottom separate paper sketch map when using;
Fig. 5 is that the present invention peels off top layer polyethylene antiadhesion barrier sketch map when using.
In the drawings: 1, bottom separate paper; 2, the overlapping part of amounting to of bottom middle opening; 3, middle level gluing polyurethane film; 4, top layer polyethylene antiadhesion barrier; 5, stripping tape.
The specific embodiment:
With reference to the accompanying drawings 1, the product that processing technique of the present invention obtained is a polyurethane film medical flexible water-proof adhesive plaster, and the water-proof adhesive plaster structure is bottom separate paper 1, middle level glue polyurethane film 3, top layer polyethylene antiadhesion barrier 4.
Bottom separate paper 1 middle opening, the central closing separate paper is overlapping to be amounted to, and wherein is pressed in an intermediary flanging, so just is easy to peel off bottom separate paper 1.Bonding coloured stripping tape 5 on the top layer polyethylene antiadhesion barrier 4 one end limits so also can easily begin top layer polyethylene antiadhesion barrier is peeled off from stripping tape.Coloured stripping tape 5 is green or red, also can be other colors.
The present invention from the production cost, raw material availability 100%, and the prior art raw material effectively use Rate 78%, the present invention greatly reduces the production cost of product; From production equipment, the product of prior art will be with PU 1cm is respectively cut on the both sides of material, must produce at special equipment, and product of the present invention can be at common production wound equipment Upper production, production and processing of the present invention is simpler; On using method, the product tool of the prior art that product of the present invention compares Use more easily advantage.
