Abstract
The utility model relates to medical treatment and nursing articles, it applies more particularly to a kind of electret-type foam, is successively made of foil electret, foam dressing and adhered layer, the foam dressing is arranged in the foil electret, the foam dressing is medical polyurethane foam dressing, and the adhered layer is Silica hydrogel.Electret-type foam application provided by the utility model, is self-adhering-type, and structure is simple, easy to use, can absorb wound fluid, builds wet healing environment, meanwhile, by the stimulation of electric field, activating microcirculation and removing stasis medicinal, analgesia detumescence can effectively mitigate the pain of wound.
Description
Technical field
The utility model relates to medical treatment and nursing articles, apply in particular to a kind of electret-type foam.
Background technique
With the development of biomaterials art, the combination of biomaterial and electrostatic field, more and more by researcher's
Concern, electrostatic field can produce bioelectrical effect, have certain curative effect to muscle and soft tissue injury；However, clinical use compared with
More wound care modes for still adding gauze class for bandage, process is tedious for this mode, and the patient feels are uncomfortable.
And also in the exploratory stage, and in the market, there is presently no sizings using the mechanism of electrostatic partner treatment wound
Medical product does not also have use in clinical treatment.
Therefore, how to overcome disadvantage mentioned above, provide that a kind of haemostatic effect is significant, mitigates the hemostatic dressing plaster of patient suffering produces
Product are one it is necessary to and meaningful thing.
Utility model content
The purpose of the utility model is to overcome above-mentioned deficiencies in the prior art, and it is deposited to provide a kind of electret-type foam
Patch, structure is simple, easy to use, can absorb wound fluid, builds wet healing environment, meanwhile, it is living by the stimulation of electric field
Blood stagnation resolvation, analgesia detumescence, can effectively mitigate the pain of wound.To solve above-mentioned technical problem, technology provided by the utility model
Scheme are as follows:
A kind of electret-type foam application, is successively made of foil electret, foam dressing and adhered layer, the foam dressing
It is arranged in the foil electret, the foam dressing is medical polyurethane foam dressing, and the adhered layer is Silica hydrogel.
Further, there is micropore in the side of the foil electret, and is spaced apart with round point shape Silica hydrogel adhered layer, with wound
Mouthful contact, by micropore, foam dressing absorbing wound exudate in bag keeps a kind of wet healing environment for wound, together
When, electret film is rich in high-pressure electrostatic, contacts with wound, release electrostatic, and activating microcirculation and removing stasis medicinal, analgesia detumescence can effectively mitigate wound
The pain of mouth.Meanwhile the tack of Silica hydrogel, facilitate the use of patient.
Further, the foil electret is prepared by fluoroplastics, and surface potential value is 1000 ~ 2000V, and side is hole
Shape, aperture 0.5-1mm.
Further, the adhered layer is coated on electret film layer by gluing process, is distributed in round point shape, dot
Diameter is 0.5-1mm.
Further, the round point shape Silica hydrogel is spaced apart with electret film layer circular hole.
Further, the medical polyurethane foam dressing, with a thickness of 3mm-6mm, every gram of liquid absorption amount is 10-15 grams.
Further, the foil electret is bag-shaped, and the utility model technique is to be put in medical polyurethane foam dressing
It in foil electret, is sealed by hot pressing, hot pressing temperature is 200-220 DEG C.
The utility model has the beneficial effects that (1) polyurethane foam dressing, as liquid-adsorption layer, imbibition and water lock ability are strong, are
Wound creates Moist healing environment.(2) electret film layer, comprehensive high-voltage electrostatic field and micro-current generate biostimulation effect to human body
The principle answered, acts on wound, can active cell normal growth, promote local blood circulation, have relieve pain, reduce swelling
The effect of.(3) the sensitization rate to skin can be reduced as adhered layer using Silica hydrogel, and hydrophobicity is strong, meeting sweat there is no harm in umbilical dystocia
The viscosity of product can paste repeatedly.(4) technique uses dotted gluing, increases the permeability of adhered layer and skin, and gas permeability is strong.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of electret-type foam application of the utility model.
Description of symbols: 1, foil electret, 2, foam dressing, 3, adhered layer.
Specific embodiment
The utility model is described further below with reference to embodiment；Following embodiment is only used for clearly illustrating
The purpose of this utility model, technical solution and advantage can not limit the protection scope of the utility model with this.
Embodiment 1:
A kind of electret-type foam of the utility model apply as shown in Figure 1, successively by foil electret 1, foam dressing 2,
Adhered layer 3 forms, and the foam dressing 2 is arranged in the foil electret 1, and the foil electret 1 is prepared by fluoroplastics,
The foam dressing 2 is medical polyurethane foam dressing, and the adhered layer 3 is made of dotted Silica hydrogel.The foil electret 1 by
Fluoroplastics are prepared, and surface potential value is 1000 ~ 2000V, and side is poroid, aperture 0.5-1mm.The adhered layer 3 is
Silica hydrogel is coated on foil electret 1 by gluing process, is distributed in round point shape, and dot diameter is 0.5-1mm.The round point shape
Silica hydrogel is spaced apart with 1 circular hole of foil electret.The medical polyurethane foam dressing, with a thickness of 3mm-6mm, every gram of liquid absorption amount
It is 10-15 grams.The foil electret 1 be it is bag-shaped, the utility model technique is that medical polyurethane foam dressing 2 is put in electret
It in film 1, is sealed by hot pressing, hot pressing temperature is 200-220 DEG C.
It should be noted that it is clear that attached drawing of this specification or more is only to the description of the drawings and the specific embodiments
Ground illustrates examples for clearly illustrating the present invention, is not limitations of the embodiments of the present invention.It is all in the utility model
Spirit and principle within made any modifications, equivalent replacements, and improvements etc., should be included in the utility model claims
Protection scope within.
