Description

A kind of dulcet nano silver antibiotic band-aid of tool
(1) technical field
The invention belongs to medical instruments field, in particular to the bandage of a kind of nanometer silver antimicrobial with aromatic odor.
(2) background technique
Bandage, also known as " hemostasis plaster " are common surgical medicine and indispensable outer of every household in daily life Wound response suddenly handles good assistant.The effect of being chiefly used in the processing of fritter wound, there is quick-acting haemostatic powder, protect the surface of a wound, prevent infection.But Only these functions or not ideal enough, such as the smell that existing bandage is not all pleasant, some even there are also peculiar smell, To cause undesirable influence to the wounded.
In recent years, people increasingly close the medical effect of the aromatic essential oils such as Forest Bath, aromatotherapy, phytocide Note.As that studies fragrance gos deep into, it has been found that fragrance is releived intense strain, pressure relief and the effects of urge people excited. For example vanilla, cloves, lavender, peppermint, turpentine oil etc. have sedation, yellow chamomile, lavender have bactericidal effect.
In addition, common bandage is only made of adhesive plaster, water absorption layer and separation layer, there is no functional component in product structure, Therefore also without bactericidal effect, although also there is the bandage of many nanometer silver antimicrobials at present, nano silver is easy to be lost, China Patent CN200920117403.9 devises a kind of nano silver antibiotic band-aid, and method therefor is coated or seeped on intermediate base layer The nanometer silver compound of saturating nano silver or silver ion, surface covers medical nethike embrane on it, and medical nethike embrane serves as barrier, prevents Nano silver is lost, but is only coated and permeated, and nano silver and intermediate base layer substance cannot be made to be firmly combined, even if one layer of covering Medical nethike embrane is still difficult to ensure that nano-Ag particles are not lost.
(3) summary of the invention
Aiming at the problems existing in the prior art, the present invention devises one kind with pleasant aromatic odor and can resist for a long time The bandage of bacterium, and use microcapsules technology, maintain essence stability and lasting lasting, ensure that nano-Ag particles do not flow It loses.
Technical scheme is as follows:
The dulcet nano silver antibiotic band-aid of a kind of tool, comprising: substrate, water absorption layer, microcapsule layer, medicine layer, anti-sticking Paper；

Further, the substrate is additionally provided with several regularly arranged air holes, and the air hole, which is set on the substrate, to be compounded with Water absorption layer, microcapsule layer, medicine layer medium position at；
Further, the separate paper is two panels, is respectively arranged on substrate both ends, and overlapped coverage medicine layer.
In the present invention,
The water absorption layer, microcapsule layer, medicine layer can be compound on substrate by medical pressure-sensing glue sticking；
The water absorption layer is nonwoven cloth material；
The drug ingedient of the medicine layer is antibiosis anti-inflammatory drug；
The microcapsules are using natural polymer chitosan and gelatin as cyst wall, using essence essential oil and nano silver as capsule Core；
The microcapsules the preparation method comprises the following steps:
(1) essence essential oil is taken, drying nano silver powder and emulsifier sodium lauryl sulfate is added, in 8000~10000r/ 15~45min is stirred under the rate of min, forms uniform lotion；
The quality dosage of the nano-silver powder is the 0.1~1% of essence essential oil quality；
The quality dosage of the emulsifier is the 1~2% of system gross mass；
The essence essential oil such as flavoring rose essence, cream jasmin france, lemon extract, lavender oil or orange flavor；
(2) chitosan aqueous acetic acid and aqueous gelatin solution are prepared, by lotion obtained by step (1) and emulsifier Span-80 It is added to 20~40min of emulsification in chitosan aqueous acetic acid, aqueous gelatin solution and glutaraldehyde are then added dropwise respectively, at 60 DEG C Stirring 2~4h of solidification, filters, and filter cake is washed with deionized, and is freeze-dried up to microcapsules；
In the chitosan aqueous acetic acid, the mass fraction of chitosan is 1~2%, the volume fraction of acetic acid is 1~ 3%；
In institute's gelatin water solution, the mass fraction of gelatin is 1~3%；
Lotion obtained by the step (1), chitosan aqueous acetic acid, aqueous gelatin solution volume ratio be 1~2:1:0.5~ 1；
The volumetric usage of the emulsifier Span-80 be chitosan aqueous acetic acid and aqueous gelatin solution total volume 1~ 5%；
The volumetric usage of the glutaraldehyde is the 5~10% of chitosan aqueous acetic acid and aqueous gelatin solution total volume.
(4) Detailed description of the invention
Fig. 1 is the structural schematic diagram in bandage section of the invention；
Fig. 2 is the structural schematic diagram of substrate；
