Pad and protective film composition, the chamber wall of the gas storage are provided with aperture, aperture meet material that water can dissolve with/
Or ventilated membrane covering, gas storage memory storage have the high concentration oxygen of pressure.
Preferably, aperture meets material and the ventilated membrane covering that water can dissolve, and the material that chance water can dissolve is covered in
On the outside of ventilated membrane.
Preferably, air-filled pore is provided with the chamber wall of the gas storage, air-filled pore is equipped with check valve.
Preferably, the water absorption pad surface scribbles soft silicone.
Preferably, the material that the chance water can dissolve uses gelatin.
Preferably, the waterproof membrane uses polyethylene.
A kind of preparation method of gas storage of wound dressing based on gas oxygen supply comprises the following steps, gas
Aperture is pre-machined on the chamber wall of body storage container, and the material and/or ventilated membrane that can be dissolved with chance water cover.
Preferably, the material that meeting water can dissolve is covered in ventilative film outer surface.
The advantage of the invention is that：(1) oxygen plays an important role in the agglutination of wound：The growth of bacterium can be controlled
With diffusion；Be conducive to revascularization；Promote the formation of collagen, the present invention utilizes the high concentration oxygen stored in gas reservoir
Gas slowly discharges, and oxygen-enriched environment is provided for wound, so that accelerating wound healing process, mitigates patient's pain sense, and be conducive to
Scar is repaired, makes wound beautiful.(2) dressing outermost layer is waterproof membrane, plays dust-proof, waterproof, anti-gas-leak, antipollution effect.
(3) high-concentration oxygen in gas storage can be filled with advance, or be filled with by air-filled pore in Clinical practice.(4) inhale
Water cushion can absorb secretion and keep wound surface clean, micro- wet, while allow oxygen again by providing oxygen-enriched ring for wound
Border.(5) water absorption pad surface can scribble soft silicone, in direct contact with the skin.The effect of soft silicone (also referred to as Silica hydrogel) is to make
The non-sticky skin of dressing, makes patient no or mitigates feeling of pain when opening.(6) dressing has protective film, effectively prevents from storing, transports
When be contaminated, when use, opens, and it is convenient to facilitate.Therefore, the distinguishing feature that the present invention has.
