Description
Technical field
The utility model is related to a kind of dressing, especially a kind of maintains wound oxygen partial pressure to promote wound healing
Produce oxygen dressing.
Background technology
In wound healing process, fibroblastic propagation, Angiogenesiss, the synthesis of collagen and promoting epidermization are all
It is wherein important factor.Either unexpected occur or surgical operation caused by wound, injured in the near future, undifferentiated
Mesenchymal cell be transformed into animal migration fibroblast, it moves into and crosses impaired wound.It is currently known into fiber finer
Born of the same parents have aerobism, and fibroblast can produce collagen to promote wound healing after being upset.Confirmed by zooscopy,
The increase of collagen synthesis speed can occur under hyperoxic conditions.On the other hand, Angiogenesiss can be subject to hypoxic tissue gradient
Stimulation, new capillary vessel can upwardly extend towards the relatively low side of oxygen concentration.Epidermis generates plain rate also to be had with oxygen partial pressure
Close, for anoxia condition, under hyperoxic conditions, epitheliosis can have higher speed.
Because wound healing needs the participation of various cell, and the various growth factors of manufacture and collagen are required for fitting
When oxygen supply just can maintain the carrying out of whole wound healing process.When organizing oxygen partial pressure to be less than particular value, part
Cytosis needed for wound healing just cannot be carried out.According to existing research data, the phagocytosis of white blood cell must be in group
Knit competence exertion effect when oxygen partial pressure is more than 30mm Hg；Collagen needed for organization healing must be in wound oxygen partial pressure
Could synthesize more than during 30mm Hg；The sclerotin nucleus formation of fibroblast also must be more than 30mm Hg in local oxygen partial pressure
Shi Caineng is carried out.Additionally, when local oxygen partial pressure is less than 40mm Hg and does not have other auxiliary treatment, diabetic
Wound will be unable to restore.
Oxygen environment, in addition to can minimizing anaerobic bacteria flora by Developing restraint, can also reduce other pathogen
Concentration.There are three kinds of sources to healing wound tissue supply oxygen：In blood with hemoglobin chemistry combine oxygen, be dissolved in
Oxygen in blood plasma and the oxygen from outside is diffused into blood plasma or organizes.In the wound on surface, all of oxygen sources
All critically important.However, in the wound of high surface area, such as in ulcer wound, the tissue only at ulcer edge or its bottom
Can obtain being sufficiently fed of blood, and the granulation tissue in growing is not in the case of having oxygen to come in from outside diffusion, must
Must be by coming from the diffusion in blood vessel and blood plasma come oxygen supply, but this is a kind of relatively inefficient process.
For maintaining the hyperoxic conditions of wound tissue, in prior art, the existing product oxygen in order to provide oxygen to wound tissue applies
Material.Known product oxygen dressing generally uses foamed material as oxygen supporting substrate, so that oxygen is led in the way of external source of oxygen
Be transported to wound perimeter after crossing foamed material, or directly in the way of dissolved oxygen by oxygen storage in foamed material.However,
External source of oxygen need to configure air shooter, the not only more inconvenience and easily cause wound sense because of dealing with improperly when using
Dye.Additionally, although foamed material air permeability is good, because gas hold easily stored during because environment temperature change etc. factor and escape
Dissipate, therefore using foamed material as oxygen supporting substrate and maintain certain oxygen concentration to be not easy to, and connecing with wound body fluid
Touch and during discharging oxygen, general foamed material its partial pressure wayward and oxygen rate of release, therefore cannot obtain
Stable wound healing effect.
Therefore, need exist for the product oxygen dressing that a kind of oxygen partial pressure making wound circumference is more than 40mm Hg, it can avoid
Produce the reaction during storage of oxygen reactant to consume, and can avoid producing oxygen reactant or reacted product because with Wound contact and
Stimulate wound.
Utility model content
