摘要
The invention discloses a micro-negative pressure foam dressing and a manufacturing method thereof, the dressing comprises a exothermic agent layer, an isolation component covering on the exothermic agent layer, an elastic memory piece disposed under the exothermic agent layer, a liquid absorbing negative pressure pad disposed under the elastic memory piece, a contact layer disposed under the liquid absorbing negative pressure pad, a sealing film disposed between the liquid absorbing negative pressure pad and the contact layer, and a bottom release film disposed under the contact layer; and in this invention, heat generated by a exothermic agent layer causes an elastic memory piece to expand downward to compress a foam layer, and after the heat dissipates completely, a micro-negative pressure is generated since a sealed environment is formed by a sealing film, a contact layer and a wound surface without a need for the VSD negative pressure technology, which is simple to operate, simple in structure, low in cost, small in volume and portable.
