Description
Technical field
The present invention relates to medical dressing technical field, more particularly to a kind of compound porous light strong absorptive is medical to be inhaled
Water cushion.
Background technology
Medical absorbents are one kind of medical dressing, are the articles for use for coating wound, to cover sore, wound or other infringements
Medical material.With the physiopathologic further investigation to wound, medical absorbents are being updated and developed.
Traditional medical dressing, in the larger wound of cladding, covering amount of bleeding, the readily permeable dressing of blood, in wound
Accumulation, it is airtight, oppress wound, be unfavorable for the healing of wound, in addition when removing dressing also easily with wound adhesion, so as to make
Into patient pain, or cause the adverse reactions such as secondary bleeding.
The content of the invention
The present invention solves the technical problem of provide a kind of compound porous light strong absorptive medical absorbents, energy
Enough prevent that adsorptive pads from contacting to be embedded into wound for a long time with skin, cause secondary injury, by air-vent, produce splendid
Gas permeability, reduce wound exudate injury to wound, accelerating wound healing after wound accumulation.
In order to solve the above technical problems, one aspect of the present invention is：
A kind of compound porous light strong absorptive medical absorbents are provided, included successively for the thin of waterproof and breathable from top to bottom
Film, the cotton core layer with water absorbing properties and the antiblocking layers for fitting in affected part；Some proper alignments are provided with the cotton core layer
Air-vent.
In the preferred embodiment of the present invention, the air-vent for circular, square or hexagon.
In the preferred embodiment of the present invention, the area of the air-vent is 0.2 ~ 100mm2。
In the preferred embodiment of the present invention, the thickness of the barrier film and the antiblocking layers for 0.01 ~
0.03mm。
In the preferred embodiment of the present invention, the barrier film is medical poisonless level polyethylene with the antiblocking layers
Film.
In the preferred embodiment of the present invention, the barrier film is netted film with the antiblocking layers, uniformly
Distribution rule permeability hole.
In the preferred embodiment of the present invention, the cotton core layer is made up of hydroscopicity nonwoven fabric, the non-woven fabrics
Water absorbent rate is more than 8g/g.
In the preferred embodiment of the present invention, the non-woven fabrics is made up of high hygroscopicity fibre, the non-woven fabrics
Water absorbent rate is more than 50g/g.
The beneficial effects of the invention are as follows：The compound porous light strong absorptive medical absorbents of the present invention, are using superabsorbent
During water material, with strong absorptive, water absorption is more than 10 times of common medical absorbents, and antiblocking layers are prevented from adsorptive pads
Contact to be embedded into wound with skin for a long time, cause secondary injury；The setting of air-vent, has adsorptive pads in cotton core layer
There is excellent gas permeability, reduce the contact area with wound, reduce injury of the wound exudate to wound after wound accumulation,
So as to reduce the constriction to wound, accelerating wound healing.
Brief description of the drawings
Fig. 1 is the structural representation of a preferred embodiment of the present invention；
The mark of each part is as follows in accompanying drawing：1st, waterproof ventilated membrane, 2, cotton core layer, 3, antiblocking layers, 4, air-vent.
Embodiment
Presently preferred embodiments of the present invention is described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, apparent is clearly defined so as to be made to protection scope of the present invention.
A kind of compound porous light strong absorptive medical absorbents, include successively from top to bottom for waterproof and breathable every
Cotton core layer 2 from film 1, with water absorbing properties and fit in the antiblocking layers 3 in affected part.Some air-vents 4 are provided with through described
Cotton core layer 2, air-vent 4 it is in irregular shape, can be circular or square or triangle, the area one of air-vent 4
As in 0.2 ~ 100mm2, the area of air-vent 4 is preferably 1 ~ 30mm2。
The thickness of the barrier film 1 and the antiblocking layers 3 is 0.01 ~ 0.03mm, and the barrier film 1 prevents adhesion with described
Layer 3 is medical poisonless level polyethylene film, and the barrier film 1 is netted film, uniform distribution rule with the antiblocking layers 3
Permeability hole.
The cotton core layer 2 is made up of non-woven fabrics, can select superabsorbent fiber（SFA）Or biomaterial passes through acupuncture eedle
The non-woven fabrics being made is pierced, biomaterial can be chitin fiber either alginate fibre, all be natural macromolecular material,
To human body without any toxicity, it can use safely.Wherein alginate fibre has high-hygroscopicity simultaneously（It is absorbable heavy equivalent to itself
11 times of liquid of amount）, it is hemostatic（Wound exudate release Ca2+ is contacted, the formation of thrombokinase can be promoted, accelerate blood clotting
Process）, into colloidality（Absorbing wound exudate, occurs Na with sepage+/Ca2+Ion exchange, in wound surface one layer of stabilization of formation
Network gel, be wound build one be beneficial to tissue growth microenvironment）, promote wound healing（Slightly sour, anaerobic or hypoxemia,
The wound climate of appropriateness moistening promotes growth factor release, stimulates cellular proliferation, and improves the power of regeneration and cell of epidermal cell
It is mobile, promote wound healing）, biocidal property（Moistening, slightly sour environmental benefits play a role in neutrophil leucocyte, and enhancing is local to kill
Bacterium ability, reduces infection rate）, reduce local pain sense（The water gel that surface is formed can effectively protect nerve ending,
Avoid environmental stimuli；It is difficult and wound adhesion, easily removal）Deng performance.
The water absorption for the non-woven fabrics being fabricated to typically all requires more than 50g/g, therefore the water imbibition of cotton core layer 2 is fabulous, inhales
Water is at least 10 times of conventional absorbent paper material.
The compound porous light strong absorptive medical absorbents of the present invention, with strong absorptive, cotton core layer 2 uses superabsorbent water
The non-woven fabrics that fibrous material is made, water absorption can be more than 10 times of conventional absorbent paper pad；Antiblocking layers 3 are prevented from adsorptive pads
Contact to be embedded into wound with skin for a long time, cause secondary injury；Through the setting of the air-vent 4 of cotton core layer 2, make
Adsorptive pads have excellent gas permeability, reduce the contact area with wound, so as to reduce the constriction to wound.
Medical absorbents in the present invention, peel strength is not less than 1.0N/cm, and rate of water absorption is less than 6 seconds, and water absorbent rate is big
In 2000%.
Embodiments of the invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize this hair
Equivalent structure or equivalent flow conversion that bright specification and accompanying drawing content are made, or directly or indirectly it is used in other related skills
Art field, is included within the scope of the present invention.
