Description
Technical 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 permitted
Multi-product is updated and updated, and equally, Medical wound adhesive bandage is also constantly updating the replacement, to adapt to the need of medical industry
Will.At present, in the market has a various Wound dressings, but these Wound dressings often deposit in some aspects insufficient and scarce
Point.Such as：The method of general therapeutic skin wound is pasted in gauze of the wound site covering provided with dressing, blend compounds band
It 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 patient
Dressing 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, especially
Some 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 Tontru
Mouth or wound adhesion, can cause wound, wound pain when separating, or even can pull the wound to have healed, wound, often will be very
Slowly the peeling off adhesion part of careful, simply cuts off adhesion part sometimes and leaves adhesion part, so, constantly carry
High 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 resists
Bacterium 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 patch
Conjunction 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 linkage
Entirety, 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 with
Detachable 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 respectively
Portion, 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 coat
Kind.
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 patch
Size, 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, third
The 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 dextran
Polymerization 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 exists
Waterproof layer is provided with patch, the liquid that can effectively prevent outside enters the inside of application, has blocked entering for outside bacterium
Enter, 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, carries
The 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 effective
The fester or blood that absorb user wound, prevent wound to be infected again, ensure drying and the health of wound.In patch
Dressing layer is also compounded with, dressing layer contains the drug ingedient of gel, and the healing to wound has good therapeutic action.Patch with
The contact site of wound is provided with tack coat, and tack coat just has good adhewsive action, and application is firmly fitted in user's
On the skin of wound, the service life of application is improved.
