The utility model relates to a silver-containing antibacterial band-aid, which sequentially comprises a silver-containing ion cotton fiber layer, a liquid absorbing layer, a backing layer and a backing support protective layer from inside to outside, wherein the backing layer comprises a plurality of strip-shaped backings which are mutually independently stuck to the outer side of the liquid absorbing layer, and two ends of each strip-shaped backing extend out of the liquid absorbing layer to be stuck to the skin around a wound; the backing support protective layer is attached to the outer side of the backing layer. The strip backing material has good flexibility, and when being used for special parts such as joints, fingertips and the like, each strip backing can be pulled independently to generate small-amplitude displacement relative to the liquid absorption layer, so that the strip backing material can be attached to the special parts such as joints, fingertips and the like, the situation of hemming and falling off is prevented, and the use performance of the band-aid is improved while the appearance of the band-aid is enriched. The silver ion-containing cotton fiber layer directly contacting the wound surface has good antibacterial effect, and silver ions in the liquid absorbing layer can play a role in inhibiting bacteria, so that bacteria are prevented from breeding in the liquid absorbing layer and reverse osmosis to the wound surface to cause infection, and the wound healing can be promoted.
Description
Technical Field
The utility model relates to the field of medical instruments, in particular to a silver-containing antibacterial band-aid.
Background
The adhesive bandage is generally used for small wounds which are shallow in surface, clean and tidy in wound, have little bleeding and do not need to be sutured, plays roles in temporarily stopping bleeding and protecting the wound surface from being infected, and plays a role in paying attention to bacteriostasis in the actual production process.
Silver ion is used as a bacteriostatic agent, has the advantages of safety, broad spectrum, long-acting property, no tolerance bacteria and remarkable bacteriostatic effect, and is an ideal bacteriostatic agent.
The modern slow-release silver ion gel material has the effects of cleaning and inhibiting bacteria on wounds, active silver ions slowly enter wound exudates from the dressing in a low quantity, and a certain concentration is kept in the exudates for a long time so as to kill most bacteria in the wounds and prevent wound infection; meanwhile, the dressing has strong absorption effect on wound exudates, and plays roles of keeping proper temperature and humidity of wounds, avoiding external pollution, protecting bare nerve endings and relieving pain.
However, the existing band-aid on the market has the following defects: firstly, the limited bactericidal effect leads to slower healing speed of wounds; secondly, due to the physiological structural characteristics, the common adhesive bandage cannot well treat the wounds at the joint parts, and the situation of hemming and falling frequently occurs.
Disclosure of Invention
The utility model aims to provide a silver-containing antibacterial band-aid, which solves the technical problems that the band-aid in the prior art is limited in sterilization effect and cannot be well attached to joint parts.
In order to achieve the above purpose, the present utility model provides the following technical solutions:
the silver-containing antibacterial band-aid comprises a silver-containing ion cotton fiber layer, a liquid absorbing layer, a backing layer and a backing support protective layer from inside to outside, wherein the backing layer comprises a plurality of strip-shaped backings which are mutually independent and adhered to the outer side of the liquid absorbing layer, and two ends of each strip-shaped backing extend out of the liquid absorbing layer to be adhered to skin around a wound; the backing support protective layer is attached to the outer side of the backing layer.
Further, the liquid absorbing layer is a polyurethane silver ion dressing layer.
Further, the backing layer is a medical adhesive-containing polyurethane film backing layer.
Further, the strip-shaped backings are arranged in parallel, and the backing support protection layer is rectangular.
Further, a release layer is arranged on the inner side of the silver ion-containing cotton fiber layer.
Compared with the prior art, the utility model has the following beneficial effects:
1. the strip-shaped backing material which is made of the polyurethane film and is arranged in parallel has good flexibility, and when being used for special positions such as joints and fingertips, each strip-shaped backing material can be independently pulled to generate small-amplitude displacement relative to the polyurethane silver ion dressing layer, so that the strip-shaped backing material can be more attached to the special positions such as joints and fingertips, the situation of hemming and falling off is prevented, the service performance of the band-aid is improved, and the appearance of the band-aid is enriched.
2. The silver ion-containing cotton fiber layer directly contacting the wound surface has the advantage of good antibacterial effect. The polyurethane silver ion dressing layer is used as a liquid absorbing layer, wherein silver ions can play a role in inhibiting bacteria, and bacteria are prevented from breeding in the liquid absorbing layer and reverse osmosis to a wound surface to cause infection, so that wound healing can be promoted.
The device has the advantages of scientific and reasonable structure, safe and convenient use and great help for people.

Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.
The embodiment of the silver-containing antibacterial band-aid comprises the following components:
the silver-containing antibacterial band-aid comprises a silver-ion-containing cotton fiber layer 1, a polyurethane silver ion dressing layer 2, a medical adhesive-containing polyurethane film backing layer 4 and a backing support protective layer 5 from inside to outside in sequence, wherein the inner side of the silver-ion-containing cotton fiber layer 1 is stuck with a release layer 3 which needs to be torn off during use.
The polyurethane film backing layer 4 containing medical adhesive comprises a plurality of strip-shaped backings, the outer side faces of the strip-shaped backings are coated with medical adhesive, the strip-shaped backings are attached to the back face of the polyurethane silver ion dressing layer 2 at intervals, and the plurality of strip-shaped backings are parallel to enable the polyurethane film backing layer 4 containing medical adhesive to be in a hollowed-out mode. The backing support protective layer 5 is rectangular, and is attached to the outer side of the medical adhesive-containing polyurethane film backing layer 4 to play a role in supporting and protecting.
The strip-shaped backing material which is made of the polyurethane film and is arranged in parallel is good in flexibility, when being used for special positions such as joints and fingertips, each strip-shaped backing material can be pulled independently to generate small-amplitude displacement relative to the polyurethane silver ion dressing layer 2, so that the strip-shaped backing material can be attached to the special positions such as joints and fingertips more, the situation that the rolled edges fall off is prevented, and the use performance of the band-aid is improved, and meanwhile the appearance of the band-aid is enriched.
The silver ion-containing cotton fiber layer 1 directly contacting the wound surface has the advantage of good antibacterial effect. The polyurethane silver ion dressing layer 2 is used as a liquid absorbing layer, wherein silver ions can play a role in inhibiting bacteria, and bacteria are prevented from breeding in the liquid absorbing layer and reverse osmosis to a wound surface to cause infection.
