Description
Technical field
The invention belongs to medical applications production technical field, be specifically related to one and exempt from overlay film anti adsorptive pads and production technology thereof.
Background technology
In people's daily life, often can meet with all kinds of hemorrhagic wound, directly with adhesive bandage, wound is affixed on for minor cut or wound, large wound be needed to be cleaned a wound by the medical worker of hospital, and carries out disinfection, then with gauze wrapping, or stick all kinds of applying ointment or plaster.But such as adhesive bandage, the gauze or apply ointment or plaster of the dressing in prior art often to occur that when bleeding amount of wound is larger blood is through gauze or the seepage situation of applying ointment or plaster, especially, when wound healing easily and the dressing such as gauze stick together, so, when wound healing and when removing gauze, can patient pain be caused, even cause secondary hemorrhage.
Traditional wound dressing, based on gauze, when wound uses, along with the healing of time and wound, can produce adhesion, during replacing, patient is very painful, and easily causes secondary wound.New pattern compress on the market adds Antiadhesive film based on non-woven fabrics, and water absorption is high, and on the basis of gauze, performance is significantly improved, but does not possess functional, as moisture retention is poor, does not have the functions such as hemostasis, sterilization.And high-end functionality dressing, as non-weaving cloths such as chitin, alginic acid calcium salt, silver ions, although have the functions such as water suction, moisturizing, sterilization, hemostasis, water absorption is not enough, and expensive.
In published Chinese patent literature, be no lack of the technical information being seen in medical dressing, slightly with exemplify as Authorization Notice No. CN2438436Y (broad-spectrum antibiotic plaster), CN1291704C (a kind of method for designing of incision applicator for postoperation), CN2696662Y (a kind of incision applicator for postoperation), CN200960223Y (self-adhesive germ free applying strapping), CN201572340U (one can medicine adding plaster), CN201879911U (a kind of Self-bonding medical plaster), publication No. CN102166370A (protecting wound to apply ointment or plaster and preparation technology), CN202122720U (a kind of plaster), CN202235923U (medical application), publication No. CN102267266A (a kind of ventilated membrane for warm subsides, its preparation method and application), CN202173511U (protective plaster for wound temporary care), CN2512411Y (nano active carbon fibre medical dressing), CN2240347Y (antiseptic nonwoven fabric medical dressing), CN202605131U (carbon fiber nanometer silver non-woven fabric medical dressing), CN2313563Y (Medical sterilized dressing) and publication number CN1381275A (a kind of medical composite non-woven cloth), etc.Be not limited to medical dressing disclosed in these patents of exemplifying all belong to band pharmic function dressing or claim therapeutic dressing, thus do not belong to medical absorbents category.
The technical information belonging to medical absorbents category can be seen in equally in Chinese patent literature; as CN201308581Y recommendation has " medical application with multilayer water absorption structure "; this patent protects leaching membrane paper to form by four layers of water accepting layer and one deck; ground floor water entry (specifically can see Instructions Page 2 the 4 to 8 row of this patent) in upper and lower two-layer nonwoven; changing when this patent structure removes after patient's wound healing or in patient treatment procedure when applying ointment or plaster, can there is the anxiety of adhesion with wound in protection leaching membrane paper.And for example CN202136483U " medical application " that provide and CN201642330U " Medical non-woven fabric mat towel " introduced is equally because structure loses the anxiety rationally and in use existed with wound adhesion.
