A kind of disposable hydrocolloid antibacterial applicationTechnical field
The present invention relates to the technical field of medical supplies, and in particular to a kind of disposable hydrocolloid antibacterial application.
Background technology
With the continuous development of scientific technology, new science and technology material is more and more, and the innovation and development of tech materials promote to be permittedMulti-product is updated and updated, and equally, Medical wound adhesive bandage is also constantly updating the replacement, to adapt to the need of medical industryWill.At present, in the market has a various Wound dressings, but these Wound dressings often deposit in some aspects insufficient and scarcePoint.Such as：The method of general therapeutic skin wound is pasted in gauze of the wound site covering provided with dressing, blend compounds bandIt is fixed.Oozed out because wound has liquid, dressing is made moist and fail, it is necessary to change in time.
Hospital often uses postoperative wound or wound after surgical site infections or processing patient wound are done to patientDressing cover, on the one hand shield, damaged once again when avoiding encountering foreign object wound or wound, obstruct air in puffball,Dirt directly contacts wound or wound；On the other hand the liquid body exudate of wound or wound is obtained dressing absorption, will not outflow, especiallySome carries the liquid of toadstool, such as fester, and flowing to healthy skin can be infected.
In the past, wound or wound dressing are typically covered using aseptic cotton, or add one layer of antiseptic gauze on aseptic cotton face,There is very big shortcoming in this dressing, on the one hand waste cotton, cotton yarn resource, it is bigger the shortcomings that be cotton, gauze often TontruMouth or wound adhesion, can cause wound, wound pain when separating, or even can pull the wound to have healed, wound, often will be verySlowly the peeling off adhesion part of careful, simply cuts off adhesion part sometimes and leaves adhesion part, so, constantly carryHigh liquid-absorbing energy and anti-blocking properties, it is Wound dressing technical problems to be solved.
The content of the invention
To be solved by this invention is the deficiencies in the prior art, and it is an object of the present invention to provide a kind of disposable hydrocolloid resistsBacterium applies.
The present invention is achieved through the following technical solutions：
A kind of disposable hydrocolloid antibacterial applies, including patch, protection sheet, paster, multiple successively in the patchConjunction has waterproof layer, water accepting layer, dressing layer and adhesive linkage, and patch is that can not be split with waterproof layer, water accepting layer, dressing layer, adhesive linkageEntirety, the protection sheet is pasted onto on the face of patch, and paster is pasted onto on the face of the adhesive linkage of patch, protection sheet and paster withDetachable connection between patch.
Preferred scheme, the paster are two panels, and two panels paster is fitted in the both sides of patch, is provided between paster overlapping respectivelyPortion, overlapping part is in the middle part of patch.
Preferred scheme, the patch are spun laced fabric.
Preferred scheme, the waterproof layer are one in water proof nonwoven cloth, polyethylene film, mould release membrance and plastic coatKind.
Preferred scheme, the water accepting layer are pharmaceutical polyvinyl alcohol film.
Preferred scheme, the size of the paster are not more than the size of patch, and the size of the protection sheet is not less than patchSize, can mutually it be torn between protection sheet and patch, the protection sheet is release liners or mould release membrance.
Preferred scheme, the dressing layer are methacrylated amylopectin, polyethylene glycol dimethacrylate, thirdThe gel that acrylamide is formed by curing by ultraviolet light.
Preferred scheme, the adhesive linkage are the gelatin of 4- vinyl benzoic acids esterification, methacrylated dextranPolymerization prepares the gel formed in the presence of free radical photo-initiation.
The antibacterial application of the present invention compared with prior art, has the following advantages and advantages：This antibacterial application existsWaterproof layer is provided with patch, the liquid that can effectively prevent outside enters the inside of application, has blocked entering for outside bacteriumEnter, ensure that the cleaning health of application, serve the effect of antibacterial, while waterproof layer does not influence washing one's face and rinsing one's mouth and taking a shower for user, carriesThe high usage experience of user.The water accepting layer of pharmaceutical polyvinyl alcohol film is additionally provided with this patch, water accepting layer can be effectiveThe fester or blood that absorb user wound, prevent wound to be infected again, ensure drying and the health of wound.In patchDressing layer is also compounded with, dressing layer contains the drug ingedient of gel, and the healing to wound has good therapeutic action.Patch withThe contact site of wound is provided with tack coat, and tack coat just has good adhewsive action, and application is firmly fitted in user'sOn the skin of wound, the service life of application is improved.

Embodiment
For the object, technical solutions and advantages of the present invention are more clearly understood, with reference to embodiment and accompanying drawing, to thisInvention is described in further detail, and exemplary embodiment of the invention and its explanation are only used for explaining the present invention, do not makeFor limitation of the invention.
Embodiment
As shown in figure 1, a kind of disposable hydrocolloid antibacterial application of the present invention, including patch 1, protection sheet, paster,Waterproof layer 2, water accepting layer 3, dressing layer 4 and adhesive linkage 5, patch 1 and waterproof layer 2, water accepting layer 3, dressing are compounded with patch 1 successivelyLayer 4, adhesive linkage 5 are the entirety that can not be split, and protection sheet is pasted onto on the face of patch, and paster is pasted onto the adhesive linkage of patch 1On face, detachable connection between protection sheet and paster and patch.Patch 1 is preferably but not limited to as spun laced fabric, spun laced fabric intensityIt is good, moist with high-hygroscopicity and speed.Waterproof layer 2 is preferably but not limited to have excellent for water proof nonwoven cloth, water proof nonwoven clothWater resistance, outside liquid intrusion is blocked, plays a part of antibacterial.Water accepting layer 3 is preferably but not limited to as pharmaceutical polyethyleneAlcohol film, pharmaceutical polyvinyl alcohol film not only has good water imbibition, and has good therapeutic action to wound, carriesThe high therapeutic effect of application.
Preferred embodiment scheme, the paster are two panels, and two panels paster is fitted in the both sides of patch, set between paster respectivelyThere is overlapping portion, overlapping part is in the middle part of patch.User only need to be from the middle bent patch 1 of application, patch 1 when in usePaster will be divided into two panels naturally, and user is easy to a paster and tears to come in patch 1, convenient for users to use, improvesThe usage experience of user.
Preferred embodiment scheme, the size of the paster are not more than the size of patch, and the size of the protection sheet is not less thanThe size of patch, can mutually it be torn between protection sheet and patch, the protection sheet is release liners or mould release membrance.
Preferred embodiment scheme, the dressing layer are methacrylated amylopectin, polyethylene glycol dimethyl alleneThe gel that acid esters, acrylamide are formed by curing by ultraviolet light.
Preferred embodiment scheme, the adhesive linkage are the gelatin of 4- vinyl benzoic acids esterification, methacrylated PortugalDextran polymerize the gel for preparing and being formed in the presence of free radical photo-initiation.
Above-described embodiment, the purpose of the present invention, technical scheme and beneficial effect are carried out furtherDescribe in detail, should be understood that the embodiment that the foregoing is only the present invention, be not intended to limit the present inventionProtection domain, within the spirit and principles of the invention, any modification, equivalent substitution and improvements done etc., all should includeWithin protection scope of the present invention.
