Abstract
The invention discloses an electret medical dressing, which mainly aims to overcome the defects of the conventional gauze dressing. Fluoroplastic is processed and refined to prepare a sponge bulking material, and a fluoroplastic electret sponge bulking material is prepared into electret medical dressings with different specifications and different shapes by electret technologies such as an electret corona method or a breakdown method and the like. The electret medical dressing has the characteristics of antibiosis, bactriostasis, antiphlogosis, pain relief, dust prevention, water prevention and high air permeability, and the effects of diminishing inflammation, preventing infection and promoting a wound to heal can be achieved without medicines. The electret medical dressing can resist acid, alkali and high temperatures, cannot be corroded and dissolved in solvents such as water, alcohol and the like, has stable performance, is nontoxic and innocent, is a novel medical product and is particularly suitable for the conditions of battle field emergency treatment, field emergency treatment and rescue and relief work.
Description
Technical field
The present invention discloses a kind of medical dressing with antibacterial bacteriostatic, is a kind of medical dressing of fluoroplastics electret specifically, belongs to field of medical products.
Background technology
Present medical wound is generally used the gauze dressing of sterilization; Apply on wound surface and bandage again; But the gauze dressing of sterilization mainly plays protection and nursing to wound, itself does not have the effect of antiphlogistic and bactericidal, just relies on medicine that Wound care is infected with anti-.
Summary of the invention
The present invention discloses a kind of have antibacterial bacteriostatic, anti-inflammatory analgetic function effect, the fluoroplastics electret medical dressing of dustproof and waterproof, good permeability.
The present invention solves the technical scheme that its technical problem takes; Fluoroplastics are processed refinement process adsorbing agent carrier; Described adsorbing agent carrier is a sponge varicosity material, adopts electret technical finesses such as electret corona method or puncture method, is processed into the electret medical dressing.
Described electret is the material to some properties, the dielectric substance of polarization and ability longer-term storage electric charge under effect of factors such as strong external electric field.In electret, there is the electrostatic field electric charge; The similar numerous passive collecting electrode of the hole of material, when airborne charged corpuscle especially submicron particle passed through these holes, quilt was stopped or is caught under the effect of electric field force; Neutral corpuscle in the air-flow is also effectively caught because of induction or polarization become dipole; Therefore, electret has outstanding blocking capability to dust, can stop the bacterial infection wound surface that dust carries.
Antibacterial and virus have natural electret state (electronegative) and are attached to usually on the airborne dust; Scatter propagation with air-flow; When they pass through the hole of electret; Because strong electrostatic field and little electric current that electret produces can stimulate antibacterial to make protein variations, Cytoplasm and the cell membrane of damage antibacterial, the surface texture that destroys antibacterial causes bacterial death.The electric field that electret forms has the obvious suppression effect to the breeding of each bacterioid.
Described fluoroplastics electret is the composite of polytetrafluoroethylene (PTFE), perfluoro second propylene (FEP), ethylene-tetrafluoroethylene copolymer materials such as (ETFE) or polytetrafluoroethylene (PTFE) and perfluoro second propylene (FEP); Adsorbing agent carrier is processed in the processing refinement; Adsorbing agent carrier is carried out the electret technical finesse, make it become electret.Described adsorbing agent carrier is the sponge varicosity material that above-mentioned fluoroplastics are processed.
Described fluoroplastics electret sponge varicosity material has good ventilative, water resistance, when the aperture of sponge varicosity material is chosen in 0.1-0.5 μ m; This diameter is the 1/2000-1/5000 of drop diameter; Be 700 times of water vapour molecule, therefore, the moisture of outside can not infiltrate; And the antiperspirant steam of health can unimpededly appear, and does not accumulate between skin and the sponge varicosity material.
The invention has the beneficial effects as follows; The electret medical dressing has the characteristic of good permeability, damp proof, antiinflammatory, antibacterial bacteriostatic; Its performance is much better than existing medication and soaks gauze dressing with the treatment nursing efficacy, and can be because of gauze and wound do not form a scab, and causing suffering to the patient makes troubles to treatment.The present invention also has the effect of antibacterial bacteriostatic, does not make medicament also can reach anti-inflammatory analgetic, aseptic effect.The present invention also has excellent water proofing property; Even moisture can not infiltrate infringement wound face or wound yet in a humid environment; And the electret medical dressing have acidproof, alkaline-resisting, high temperature resistant, do not receive solution such as the water insoluble and ethanol of burn into, stable performance, nontoxic, safe and reliable; Be a kind of novel therapeutic articles for use, use under particularly suitable first aid of battle field, field emergency, the rescue and relief work situation with naturopathy function.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is an electret medical dressing sketch map of the present invention.
The specific embodiment
As shown in Figure 1, fluoroplastics are processed refinement process sponge varicosity material, adopt electret technical finesses such as electret corona method or puncture method, make it become electret, the materials processing of electret sponge varicosity is become the difform medical dressing of different size.
Fluoroplastics electret medical dressing described in the present invention; Solved the deficiency that used medical dressing exists; Utilize the performance of its antibacterial bacteriostatic and dustproof and waterproof, good permeability; Realized not making medicament to prevent that traumatic infection from carrying out trauma care and nursing efficacy, cooperated with medicine and can obtain better therapeutic.That the electret medical dressing also has is acidproof, alkaline-resisting, high temperature resistant, do not receive solution such as the water insoluble and ethanol of burn into; Stable performance; Nontoxic, safe and reliable; Be a kind of novel therapeutic articles for use, use under particularly suitable first aid of battle field, field emergency, the rescue and relief work situation with naturopathy function.
Embodiment disclosed by the invention is preferred embodiment, does not limit practical range of the present invention, all in the principle that the present invention discloses variation, distortion, replacement, all belong to patent application protection domain of the present invention.
