Abstract
The utility model discloses a kind of water-proof breathable properties foil electret, be made up of three-decker, innermost layer is foil electret, intermediate layer is medical pressure-sensing glue-line, outermost layer is the PU film with waterproof and breathable performance, and outermost layer PU membrane area is greater than the foil electret area of innermost layer, is fixed by medical pressure-sensing glue-line and human body.The utility model is rational in infrastructure, effectively can solve existing foil electret long duration of action easily causes uncomfortable reaction and limitation of activity problem in patient pain position.
Description
Technical field
The utility model relates to a kind of external application type medical pain relieving water-proof breathable properties foil electret.
Background technology
Electret is the functional material with long term storage polarization charge ability.Histoorgan such as skin, bone, muscle and the neural blood vessel etc. of human body have good electret.Research finds, electret effect is the base attribute of human life activity; Electret state (charge polarization of tissue) is present in the overall process of vital movement.The adjustment of tissue electret state, change control the biological phenomena such as activation resulting from transmission, the biologically of cell, electrolytical balance, enzyme function of nerve signal effectively.
Tissue sustain damage or pathology time, its biological electret state will be damaged, and changes originally normal polarized state, produces demarcation potential poor, affect normal vital movement, occur the phenomenons such as swelling, pain, heating.Foil electret has very strong negative electrical charge polarization performance, and the electret state effectively can correcting the pain of injury or diseased region is unbalance, recovers the normal electret state of tissue, thus eliminates or alleviating pain.Foil electret in the market adopts medical proof fabric to fix mostly, poor air permeability and can not waterproof, and long duration of action is in patient pain position, and patient can produce sense of discomfort; In addition, because medical proof fabric has certain thickness and poor flexibility, when acting on patient articular position, certain impact can be produced on the autonomic activities of patient.
The purpose of this utility model is to provide a kind of water-proof breathable properties foil electret of easy to use, waterproof and breathable, external application type.
The utility model is achieved through the following technical solutions:
A kind of water-proof breathable properties foil electret, it is characterized in that: be made up of three-decker, innermost layer is foil electret, intermediate layer is medical pressure-sensing glue-line, outermost layer is the PU film with waterproof and breathable performance, and outermost layer PU membrane area is greater than the foil electret area of innermost layer, is fixed by medical pressure-sensing glue-line and human body.
Foil electret is a kind of electronegative polytetrafluoroethylene (PTFE) or polyhexafluoropropylene or both copolymer electret films; PU film thickness is 0.01-0.03mm.Due to the gas permeability of PU film, act on patient pain position patient and can not produce any discomfort sense; Its water proofing property and superthin structure design can make patient's daily routines unrestricted.
Beneficial effect of the present invention is: solve existing foil electret long duration of action easily causes uncomfortable reaction and limitation of activity problem in patient pain position.
Accompanying drawing explanation
With reference to the accompanying drawings the present invention is described in further detail below.
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
As shown in Figure 1, a kind of water-proof breathable properties foil electret, is made up of three-decker, and innermost layer is foil electret 2, and intermediate layer is medical pressure sensitive adhesive 3, and outermost layer is PU film 1.Innermost layer is foil electret 2 is that PU film 1 is connected by intermediate layer medical pressure sensitive adhesive 3 with outermost layer, and wherein foil electret is a kind of electronegative polytetrafluoroethylene (PTFE) or polyhexafluoropropylene or both copolymer electret films; Outer PU film is waterproof ventilated membrane, and thickness is 0.01-0.03mm.And outermost layer PU membrane area is greater than the foil electret area of innermost layer, is fixed by medical pressure-sensing glue-line and human body.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but any change is done in its shape or structure; all have identical with the application or akin technical scheme, all drops within protection domain of the present utility model.
