Description
Technical field
The present invention relates to a kind of medical supplies, are based on a variety of high molecular materials or with it more particularly, to one kind for load
The structure of composite membrane (thin slice) of body composition generates the dressing and its production technology that oxygen is wound oxygen supply.
Background technique
After people are injured, wound care can be carried out using wound dressing.It is well known that oxygen rises in the agglutination of wound
Important function：It can control the growth and diffusion of bacterium；Simultaneously because the destruction of wound perimeter capillary causes cell hypoxia
It is unfavorable for cytothesis；And external oxygen supply is conducive to the regeneration of cell to accelerate the healing of wound.Wound traditional at present applies
Material is unable to reach this effect.Following three kinds can be divided by its material therefor and function：1, inertia dressing：It is created with protection
Face has the advantages that absorbability, production are simple and cheap；2, double acting dressing：This kind of dressing can be using caused by it
Local environment promotes wound healing, has stronger absorption function.Such as the absorbing film made of polyamino Ethyl formate material,
Or the netted water imbibition polymer of 3 D stereo being made of gelatin, polysaccharide, more dielectric compounds and methacrylic resin, or
It is made of polyurethane and polyoxyethylene glycol porous foam.3, biological active dressing：Using high molecular material with
The associativity dressing that biomaterial is processed into through new and high technology method, have double-layer structure, outer layer application high molecular material,
Provide the barrier function for being equivalent to epidermis；The main material that internal layer is selected is collagen, chitosan and calcium alginate, has biology
Compatibility, preferable water imbibition, gas permeability, adhesion and antibacterial, anastalsis.
Although traditional dressing can protect wound, promoting wound healing in various degree, since wound is in agglutination
In anaerobic condition, healing effect is often bad.
Therefore, it is badly in need of a kind of dressing that can independently supply oxygen at present, provides oxygen-enriched environment for wound, reduce because of capillary
It is destroyed rear cell indolence due to anoxic, mitigates patient pain.
Summary of the invention
It is an object of the invention to overcome drawbacks described above of the existing technology, a kind of oxygen supply dressing is provided, dressing is passed through
Oxygen-enriched environment is provided for wound.
To achieve the above object, technical scheme is as follows：
A kind of wound dressing of structure of composite membrane (thin slice) oxygen supply based on multiple material composition, which is characterized in that by upper
It arrives down successively mainly by anti-gas-leak protective film, water cushion of attracting deposit, supplies oxygen film (thin slice) and permeable water-absorbent material composition；The oxygen supply film
(thin slice) (3) are composite membrane (thin slice) structure of air-and water-permeable, and oxygen supply film (thin slice) (3) is to include oxidant (example：Percarbonic acid
Sodium) and catalyst (example：Manganese dioxide) etc., the outer porous film of package.
Preferably, permeable water-absorbent material is good penetrability, and guidance liquid quickly enters the material for oxygen layer, such as hot wind nonwoven
Cloth, surface are coated with soft silicone, also can surface cover sodium alginate.
Preferably, supplying oxygen oxidant in film (thin slice) (3) is SODIUM PERCARBONATE), catalyst is manganese dioxide etc..
Preferably, water suction water storage pad is made of high-molecular gel.
Preferably, dressing includes at least one oxygen supply film (thin slice) structure, and multiple oxygen supply film (thin slice) structures can arrange
Combination.
Preferably, the material for having certain surface tension can be selected in anti-gas-leak protective film, can accommodate more oxygen, simultaneously
Certain high pressure oxygen environment is formed in wound surface, or carries out certain structure design.
It is a kind of that generate oxygen based on a variety of high molecular materials or the structure of composite membrane formed using it as carrier (thin slice) be to hurt
The preparation for oxygen layer of the dressing of confession oxygen, carries out in closed dry environment.
Good seal between the anti-gas-leak protective film and patient skin of dressing.
It can be seen from the above technical proposal that the present invention has beneficial effect：
(1) oxygen supply film (thin slice) reacts after meeting wound fluid and can provide oxygen for wound, is conducive to accelerate wound
Mouth agglutination；Mitigate patient pain.
(2) dressing outermost layer is anti-gas-leak protective film, plays dust-proof, waterproof, anti-gas-leak, antipollution effect.
(3) dressing includes at least one oxygen supply film (thin slice) structure, and multiple oxygen supply film (thin slice) structures can be with permutation and combination.
(4) attract deposit water cushion can the chemical reactants such as water after absorbing reaction, oxygen can also be stored, keep wound oxygen dense
Degree.
(5) permeable water-absorbent material absorbs wound exudate, keeps wound surface clean, by the water of permeable water-absorbent material into
Enter for oxygen layer, chemically reacted with for oxygen layer, compound solution enters water cushion of attracting deposit and will not flow back after reaction, and generating oxygen can
Passed through with two-way, so that oxygen be made to be able to enter wound, promotes cell growth.
(6) permeable water-absorbent material surface, which can cover sodium alginate, can also be coated with the similar materials such as soft silicone, straight with skin
Contact.The effect of soft silicone (also referred to as Silica hydrogel) is to make dressing adhesion skin, makes patient no when opening or mitigates pain
Pain.Therefore, the distinguishing feature that the present invention has.

As shown in Fig. 3,4,5, multiple oxygen supply film (thin slice) structural arrangement combinations.It can be cut according to wound size when use
It cuts；When handling minor cut or wound, dressing area is small, uses single sodium carbonate peroxide film (thin slice)；When for big wound, dressing
Area is big, may be designed to multiple sodium carbonate peroxide films (thin slice) and is arranged in a combination, if you need to shear, only need to according to shape of wound and
Size shears the dressing of corresponding size, opens inner layer protective film 1, and be fixed on skin, notices that edge reserves the anti-of one fixed width
Moisture film 1 is to realize sealing；The dressing is easy to use.
The above, the preferable specific embodiment only of the invention in art of wound dressings, the present invention can also cure
Other field is learned to apply such as solid oxygen ventilator, for oxygen layer control structure can equal control oxygen production quantity, to solve
The certainly defect of similar solid aerator at present, scope of protection of the present invention is not limited thereto, any to be familiar with the art
Technical staff is subject to equivalent replacement in the technical scope that the present invention discloses according to the technical scheme of the invention and its inventive conception
Or change, it should be covered by the protection scope of the present invention.
