Abstract
The invention belongs to the technical field of articles for wound dressings and particularly relates to a micro-negative-pressure super-absorption wound dressing. The micro-negative-pressure super-absorption wound dressing comprises a first surface layer, a second surface layer opposite to the first surface layer, and the first surface layer which is made of anti-adhesion mesh films contacts with skin; peripheral edges of the first surface layer and the second surface layer are connected to form a cavity, and a medical foam layer and a liquid lock layer are formed in the cavity and connected with each other; the medical foam layer is close to the first surface layer and connected with the same, and the liquid lock layer is close to the second surface layer and connected with the same. The micro-negative-pressure super-absorption wound dressing has the advantages of high absorbability, capability of continuously absorbing a great amount of exudates to form a micro-negative-pressure environment, reduction of wound impregnation, realization of dual adjustment functions including water locking and wound moisture conservation, capability of providing a better environment for wound healing and avoidance of wound adhesion and wound secondary damages.
Description
Technical field
The invention belongs to wound dressing apparatus technical field, particularly relate to a kind of tiny structure super-absorbent wound dressing.
Background technology
At present, hindering the refractory wound surface such as scald wound, various types of ulcer, pressure ulcer, in the treatment of various surgical site infections and trauma wound, the particularly exudative wound surface of all kinds of camber, common means adopt common wound dressing and gauze.Common wound dressing and gauze, in the process used, also exist defect: one is, because its absorbing fluid is limited in one's ability, so can not continue, a large amount of absorbing wound exudate, cause wound surface to flood, wound dressing and yarn and the adhesion of wound surface phase, be unfavorable for wound healing; Two are, because its absorbing fluid is limited in one's ability, so need frequent replacing wound dressing and gauze, thus bring secondary damage to wound surface; Three are, do not possess lock water function, can not provide the good environment promoting wound healing.
Summary of the invention
The object of the invention is to solve above-described technical problem, one is provided to have high-absorbable, can continue, absorb transudate in a large number, form tiny structure environment, reduce wound surface dipping, water can be locked and keep wound surface humidity dual regulation, the better environment promoting wound healing is provided, wound surface is non-caked, and avoid the tiny structure super-absorbent wound dressing of wound secondary injury, its technical scheme is as follows:
Tiny structure super-absorbent wound dressing, is characterized in that, described tiny structure super-absorbent wound dressing comprises opposing the second top layer in contact the first top layer of skin and the first top layer, and the first top layer is anti nethike embrane; First top layer forms cavity after being connected with the periphery edge place on the second top layer, is provided with Medical foam layer and lock liquid layer in cavity; Medical foam layer is connected with lock liquid layer, and Medical foam layer closes on the first top layer and is connected in the first top layer, and lock liquid layer closes on the second top layer and is connected in the second top layer.
Optimal way is, described imbibition, lock liquid layer are the mixture of hydroscopic high-molecular resin and cotton fiber.
Optimal way is, the second described top layer is non-woven fabrics.
First top layer of the present invention can be connected by any-mode with the second top layer, comprises and bonding together, and can be integral adhesive, also can be part bonding (such as dot adhesive or strip are bonding).First top layer contacts with wound surface, and anti nethike embrane can make itself and wound surface adhesion, avoids wound secondary injury during replacing.
Medical foam layer of the present invention can be connected by any-mode with lock liquid layer, and comprising and bonding together, can be integral adhesive, also can be part bonding (such as dot adhesive or strip are bonding).Medical foam layer is adjoining with the first top layer and be connected with the first top layer, and can increase the flexibility to wound, when dressing is used, wound is more comfortable, compliance good and have protective pad decompressing effect concurrently.Lock liquid layer closes on mutually with the second top layer and is connected in the second top layer, and the mixture of hydroscopic high-molecular resin and cotton fiber can make that dressing continues, a large amount of absorbing wound exudate, avoids wound to flood; And original position can retain transudate, there is lock water function, the humidity of this wound surface environment in cavity can be regulated, thus promote wound healing; The absorption transudate continued can form tiny structure environment in subenvironment, produces barometric gradient, accelerates wound healing.Lock liquid layer has water suction and lock water dual-use function.
Medical foam layer of the present invention can be connected by any-mode with the first top layer, comprises and bonding together, and can be integral adhesive, also can be part bonding (such as dot adhesive or strip are bonding).
Lock liquid layer of the present invention can be connected by any-mode with the second top layer, comprises and bonding together, and can be integral adhesive, also can be part bonding (such as dot adhesive or strip are bonding).
The invention has the beneficial effects as follows: there is high-absorbable, can continue, absorb transudate in a large number, form tiny structure environment, reduce wound surface dipping, water can be locked and keep wound surface humidity dual regulation, the better environment promoting wound healing is provided, wound surface is non-caked, avoids wound secondary injury.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Detailed description of the invention
Embodiment is illustrated below in conjunction with Fig. 1:
As shown in Figure 1, tiny structure super-absorbent wound dressing, it is anti nethike embrane that described tiny structure super-absorbent wound dressing comprises opposing the second top layer, top layer 2, first 1 in contact the first top layer 1 of skin and the first top layer 1; First top layer 1 forms cavity 3 after being connected with the periphery edge place on the second top layer 2, is provided with Medical foam layer 4 and lock liquid layer 5 in cavity 3; Medical foam layer 4 is connected with lock liquid layer 5, and Medical foam layer 4 closes on the first top layer 1 and is connected in the first top layer 1, and lock liquid layer 5 closes on the second top layer 2 and is connected in the second top layer 2.Described lock liquid layer is the mixture of hydroscopic high-molecular resin and cotton fiber.The second described top layer is non-woven fabrics.
Wherein the periphery edge place on the first top layer and the second top layer adopts medical pressure-sensitive adhesive to be mutually bonded together.All to be bondd by medical pressure-sensitive adhesive between Medical foam layer and lock liquid layer or part adhesive is fixed together.
The occupation mode that the present invention is concrete: 1, uses front normal saline to clean a wound, and dries periwound skin gently; 2, this dressing of choice for use 2cm larger than wound covers wound; 3, after absorbing transudate, this dressing dilation is close to dressing replaceable during edge.
It is fixing that the present invention can coordinate self adhesive bandage suitably to pressurize at dressing extenal fixation, is more conducive to the laminating of dressing and wound surface, healing acceleration.
Result of use of the present invention is that gauze absorbs the 10-20 of transudate ability doubly.
In the present invention, unless otherwise clearly defined and limited, the term such as term " connection ", " fixing " should be interpreted broadly.Such as, can be fixedly connected with, also can be that dismounting connects, or one connects; It can be mechanical connection; Can be directly be connected, also can be indirectly be connected by intermediary.For the ordinary skill in the art, above-mentioned term concrete meaning in the present invention can be understood as the case may be.
