Therefore, the elastic electret composite membrane has the advantages of being simple in structure and convenient to use. Particularly, the electret composite membrane extends well when used in human body parts where the range of movements are large. The relative displacement of injured human body parts is difficult, thereby improving the treatment outcome of the electret membrane.
Description
Technical field
The utility model relates to a kind of foil electret, is specifically related to a kind of rubber-like electret composite membrane.
Background technology
Electret is meant ability long term storage electric charge and keeps the functional material of polarized state.Because most of biological tissues such as skin, blood or protein and large biological molecule all are biological electrets; They are keeping intrinsic electrical phenomena all the time in the organism metabolic processes, with existing the behavior of electricity to be called biological electret state in large biological molecule or the biological tissue.Research shows; The change of biological tissue's electret state can cause the generation and the development of linked groups's disease; And the electrostatic effect and the little electric current that utilize electret to produce can make the electret state of the relevant damaged tissues of organism be able to repair, thereby reach the purpose of treatment disease.
In the prior art, electret is prepared as foil electret, then foil electret is fixed on the organism damaged part, thereby reach the effect of treatment.But, at present, when foil electret being fixed on the bigger position of human synovial or other movable amplitude, because foil electret is to lean on the adhesive plaster of periphery to be bonded on the skin; Area is smaller, and the position activity is too big when pasting, when exceeding deformation range and the adhesion of common adhesive plaster; And foil electret do not have elasticity, and not flexible is so obscission takes place in regular meeting; Or the adhesive plaster modification is excessive, can not bounce back, and cause foil electret can not be close to skin.。
The utility model content
Defective to the prior art existence; The utility model provides a kind of rubber-like electret composite membrane; Has advantage simple in structure and easy to use; When especially it being applied in the bigger position of physical activity amplitude, relative displacement takes place with respect to the human body damaged part is difficult in the electret composite membrane, thereby has improved the result of treatment of foil electret.
The technical scheme that the utility model adopts is following:
The utility model provides a kind of rubber-like electret composite membrane, comprising: foil electret, isolation tunic and adhesive parts; One side of said isolation tunic is fixedly connected with the adhesive faces of said adhesive parts, and the another side of said isolation tunic is fixedly connected with a side of said foil electret.
Preferably, the area of said foil electret is less than the area of said isolation tunic, and the area of said isolation tunic is less than the area of said adhesive parts.
Preferably, said isolation tunic is the rubber-like nonwoven; Said adhesive parts is the unidirectional spun laced fabric adhesive plaster that degree of drawing is arranged.
Preferably, the elasticity direction of said nonwoven is identical with the draw direction of said spun laced fabric adhesive plaster.
Preferably, the mode that is fixedly connected with a side of said foil electret of the another side of said isolation tunic is bonding.
Preferably, the mode that is fixedly connected with a side of said foil electret of the another side of said isolation tunic is that single-point is bonding.
Preferably, the bonding adhesive spots of said single-point is positioned at the center position of said isolation tunic.
Preferably, a side of the another side of said isolation tunic and said foil electret is bonding through double faced adhesive tape.
Preferably, also comprise: barrier paper; Said barrier paper is bonded at the another side of said foil electret.
Preferably, said foil electret is microporous teflon membran or polypropylene superfine fiber film or nitrocellulose microporous membrane.
The beneficial effect of the utility model is following:
The utility model provides a kind of rubber-like electret composite membrane; Has advantage simple in structure and easy to use; When especially it being applied in the bigger position of physical activity amplitude; Therefore relative displacement takes place with respect to the human body damaged part is difficult, thereby has improved the result of treatment of foil electret owing to have good extensibility in the electret composite membrane.
Description of drawings
The structural representation of the rubber-like electret composite membrane that Fig. 1 provides for the utility model;
Wherein, 1-foil electret; 2-isolates tunic; The 3-adhesive parts.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated:
As shown in Figure 1, the utility model provides a kind of rubber-like electret composite membrane, comprising: foil electret, isolation tunic and adhesive parts; One side of said isolation tunic is fixedly connected with the adhesive faces of said adhesive parts, and the another side of said isolation tunic is fixedly connected with a side of said foil electret.Wherein, isolating the mode that the another side of tunic is fixedly connected with a side of foil electret is that single-point is bonding, for example: bonding etc. through double faced adhesive tape, generally in the middle part.For increasing the fastness that foil electret uses, the area of foil electret is isolated the area of the area of tunic less than adhesive parts less than the area of isolating tunic.
In addition, for increasing the extensibility of electret composite membrane, isolate tunic and can select the rubber-like nonwoven for use; Adhesive parts is selected the unidirectional spun laced fabric adhesive plaster that degree of drawing is arranged for use.And the elasticity direction of nonwoven is identical with the elasticity direction of spun laced fabric adhesive plaster.Be the power loss that prevents to store in the foil electret, need be in the another side of foil electret bonding one deck barrier paper.In addition, in the utility model, foil electret can be microporous teflon membran or polypropylene superfine fiber film or nitrocellulose microporous membrane.Through the film of above-mentioned three kinds of materials, can effectively store electric charge.
The method for using of the rubber-like electret composite membrane that the utility model provides is:
At first divest the barrier paper that the foil electret another side adheres to, make foil electret be close to the human body damaged skin then, at this moment, because the adhesive parts employing is unidirectional resilient spun laced fabric adhesive plaster; Therefore, need to guarantee that the flexible direction of spun laced fabric adhesive plaster is consistent with the limb activity direction, simultaneously; Note to guarantee that limbs are not closely contacting with foil electret under the extended state, through the viscosity position foil electret is fixed on the surface of damaged skin then, like this; When limbs became bent, adhesive plaster was stretched, and was resilient owing to isolate tunic; So spun laced fabric adhesive plaster and isolation tunic overall length stretch, at this moment; Because of foil electret is that single-point adheres to isolating tunic, so the foil electret of innermost layer need not receive pulling force, adhesive plaster is enough dealt with modification power; When limbs are stretched, be resilient owing to isolate tunic, the adhesive plaster of pulling back is oppressed at foil electret, guarantees that foil electret is close to skin.
Therefore, the rubber-like electret composite membrane that the utility model provides has advantage simple in structure and easy to use; When especially it being applied in the bigger position of physical activity amplitude; Therefore relative displacement takes place with respect to the human body damaged part is difficult, thereby has improved the result of treatment of foil electret owing to have good extensibility in the electret composite membrane; And the utility model takes all is the raw material that market is prone to buying, is prone to mechanization large-scale production.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be looked the protection domain of the utility model.
