Abstract
A wet-developing cotton dressing comprises a release layer, a liquid absorbing layer, an adhesive layer and a protective layer, wherein the liquid absorbing layer is arranged on the release layer, the adhesive layer is arranged on the liquid absorbing layer, and the protective layer is arranged on the adhesive layer; the utility model has the advantages that: the condition of the exudate can be observed at any time, medical staff can be reminded to timely replace dressings, and the workload of the medical staff is reduced.
Description
Technical Field
The utility model relates to the field of medical dressings, in particular to a wet foam-displaying dressing.
Background
The medical dressing is an important medical product, is usually applied to the wound of a patient in the treatment processes of operation, dressing change and the like, plays a role in stopping bleeding and protecting the wound, so that the wound can be quickly healed, the foam dressing has high absorption characteristic and excellent exudate locking capacity, can maintain the micro-humid environment for healing the wound, promotes the growth of endothelial cells and keratinocytes, and avoids the new granulation tissue from being mechanically damaged again in a closed environment, so that the pain of the patient is relieved, the healing of the wound is promoted, and the micro-acid environment in the closed state directly inhibits the growth of bacteria, is beneficial to the reproduction and the function of leucocytes, and can prevent and control infection.
Because a slightly closed environment needs to be maintained, the risk of bacterial infection is reduced, patients and medical staff cannot open the foam dressing to observe the state of an illness, the color of wound exudates is mostly not obvious, the color difference of the exudates needs to occur for a long time, and the difficulty is caused for the medical staff to observe the state of an illness. And when the absorption seepage area exceeds the wound area, the foam dressing should be replaced in time, and medical care personnel can replace the dressing in time without delaying the state of an illness by observing the dressing in real time.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a wet cotton dressing that shows bubble when the exudate infiltration, can appear obvious colour change fast, shows the exudate condition, makes medical personnel in time know the cotton dressing application current situation of bubble, and patient and family members also can in time remind medical personnel to change according to the observation result, and the help patient is recovered as early as possible.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the wet foam dressing comprises a release layer, a liquid absorbing layer, an adhesive layer and a protective layer, wherein the liquid absorbing layer is arranged on the release layer, the adhesive layer is arranged on the liquid absorbing layer, and the protective layer is arranged on the adhesive layer.
The wet foam-developing cotton dressing is characterized in that the leuco dye is uniformly dispersed in the adhesive layer, and the color developing agent is uniformly dispersed between the liquid absorbing layer and the adhesive layer.
The wet foam-developing cotton dressing is characterized in that the leuco dye is one or more of crystal violet, methyl red, phenolphthalein, bromocresol purple and bromocresol green, and the color developing agent is one or more of citric acid, sodium bicarbonate, sodium carbonate and metal hydroxide.
The wet foaming cotton dressing is characterized in that the adhesive layer is polyurethane pressure-sensitive adhesive, and the water vapor transmission rate is more than 2000g/day square meter.
The wet foam-displaying cotton dressing is characterized in that the release layer is made of single-sided silicon paper material.
The wet foam-displaying cotton dressing is characterized in that the liquid absorption layer is polyurethane foam.
The utility model has the advantages that:
1. the condition of the exudate can be observed at any time, and medical care personnel can be reminded to change dressings in time;
2. reducing the workload of medical staff.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
Detailed Description
As shown in fig. 1, a wet foam dressing comprises a release layer 1, a liquid absorbing layer 2, an adhesive layer 3 and a protective layer 4, wherein the liquid absorbing layer 2 is arranged on the release layer 1, the adhesive layer 3 is arranged on the liquid absorbing layer 2, and the protective layer 4 is arranged on the adhesive layer 3, and is characterized in that a wet developer 5 is uniformly dispersed between the adhesive layer 3 and the liquid absorbing layer 2, the wet developer 5 is formed by combining a leuco dye and a color developing agent, the adhesive layer 3 is solvent-free, the protective layer 4 is a transparent colorless polyurethane film, the leuco dye is uniformly dispersed in the adhesive layer 3, the color developing agent is uniformly dispersed between the liquid absorbing layer 2 and the adhesive layer 3, the leuco dye is one or more of crystal violet, methyl red, phenolphthalein, bromocresol violet and bromocresol green, the color developing agent is one or more of citric acid, sodium bicarbonate, sodium carbonate and metal hydroxide, the adhesive layer 3 is a polyurethane pressure-sensitive adhesive, the water vapor transmission rate is more than 2000g/day square meter, the release layer 1 is a single-sided silicon paper material, and the liquid absorbing layer 2 is polyurethane foam.
The present invention will be further explained by taking the leuco dye as phenolphthalein and the color-developing agent as sodium carbonate as an example.
Select leuco dyestuff to be phenolphthalein, the developer is sodium carbonate, mixes adhesive layer 3 and leuco dyestuff phenolphthalein in the high machine that mixes under the vacuum state and mixes evenly, uses the coating machine coating on the protective layer 4 of polyurethane film, through heating curing shaping in the vacuum drying oven, combines it together through the multiple equipment with the imbibition layer 2 of surperficial even spraying wine developer sodium carbonate, during the use, separation type layer 1 will the utility model discloses imbibition layer 2 covers in the wound, when the exudate infiltration, the exudate sees through imbibition layer 2 and produces the reaction with wet developer 5 and takes place the colour change, can observe the exudate condition outside protective layer 4, makes medical personnel in time know dressing application current situation, and patient and family members also can in time remind medical personnel to change according to the observation result, help patient's recovery.
Above is the utility model discloses a preferred embodiment, all rely on the utility model discloses the change that technical scheme made, produced functional action does not surpass the utility model discloses during technical scheme's scope, all belong to the utility model discloses a protection.
