Abstract
The utility model relates to a medical water-resistible and breathable film. The medical water-resistible and breathable film comprises a substrate layer, and a PTFE film layer is compounded on the substrate layer in the manner of hot-pressing. The medical water-resistible and breathable film is composed of the substrate layer and the PTFE film layer which is compounded on the substrate layer, the substrate layer has good breathability, the PTFE film layer is provided with a fibril-shaped microporous structure, the porosity rate is more than 85%, 1.4 billion micropores are formed in the PTFE film layer per square centimeter, and the micropores in the PTFE film layer is characterized of being good in breathability and water resistance. Therefore, the medical water-resistible and breathable film has the advantages of being good in breathability and water resistance, and the problem that an existing medial film is water-resistible but bad in breathability or breathable but bad in water-resistance is solved. When the medical water-resistible and breathable film is used, the substrate layer rubs with clothes on body or the air, static electricity is generated, and human body generates negative charges. A trace of negative charges can excite nerves of people, people can feel mental relaxed and pleasant, therefore, a patient has a good mood, and the patient can pull through quickly.
Description
Technical field
This utility model belongs to the medical products field, is specifically related to a kind of waterproof and breathable and can produces the waterproof ventilated membrane that is used for medical treatment of static.
Background technology
In the medical products technical field, medical film is a kind of important medical products, and it is a kind of medical assistant product.Medical film can be used for treatment of wounds, wound protection etc., existing medical film exists waterproof but breathability is poor, good permeability but problems such as waterproof difference, when treatment of wounds, though adopt waterproof but the medical film of breathability difference can prevent that sealing is to the invasion of wound, but breathability missionary society causes bad phenomenon such as wound healing rots slowly, serious meeting causes the skin of wound circumference to give birth to skin ulcer, and then increases the weight of the state of an illness; Though and adopt good permeability but the medical film of waterproof difference can well be breathed freely, owing to non-watertightly be easy to cause wound because of the inflammation infection that gets wet.Therefore, a kind of not only waterproof of exploitation but also ventilative medical film have very social meaning and value.
Summary of the invention
The purpose of this utility model is the waterproof ventilated membrane that is used for medical treatment that provides a kind of waterproof and breathable at the deficiencies in the prior art and can produce static.
The purpose of this utility model is achieved in that a kind of waterproof ventilated membrane for medical treatment, comprises substrate layer, and described substrate layer is provided with the PTFE rete, and described PTFE rete is compounded on the substrate layer by the compound mode of hot pressing.
Described substrate layer is the non-woven fabrics of every weight per square meter 60-80 gram.
The thickness of described PTFE rete is the 0.5-2 millimeter.
This utility model beneficial effect compared with prior art is: this utility model is made up of substrate layer and the PTFE rete that is compounded on the substrate layer, the substrate layer good permeability, the PTFE rete has fibril shape microcellular structure, porosity is more than 85%, every square centimeter has 1,400,000,000 micropores, and but the micropore on the PTFE rete has characteristics ventilative the energy waterproof, a kind of waterproof ventilated membrane for medical treatment of the present utility model so just has waterproof and ventilative advantage, has solved the waterproof that existing medical film exists but breathability is poor, good permeability but waterproof difference problem; Substrate layer adopts non-woven fabrics, non-woven fabrics will produce static with medicated clothing or the windage of health so in use, and then to human body generation negative charge, and the nerve that the negative charge of trace can stimulate the people, make people's mental relaxation, joyful, and then to the mood that patient brings, so just help patient to get well.
Description of drawings
Fig. 1 is the structural representation of a kind of waterproof ventilated membrane for medical treatment of this utility model.
Fig. 2 is the vertical view of Fig. 1.
Among the figure: 1, substrate layer 2, PTFE rete.
The specific embodiment
Below in conjunction with drawings and Examples this utility model is further described.
Embodiment 1
As depicted in figs. 1 and 2, a kind of waterproof ventilated membrane for medical treatment comprises substrate layer 1, and described substrate layer 1 is provided with PTFE rete 2, and described PTFE rete 2 is compounded on the substrate layer 1 by the compound mode of hot pressing.
This utility model is made up of substrate layer and the PTFE rete that is compounded on the substrate layer, the substrate layer good permeability, the PTFE rete has fibril shape microcellular structure, porosity is more than 85%, every square centimeter has 1,400,000,000 micropores, and but the micropore on the PTFE rete has characteristics ventilative the energy waterproof, a kind of waterproof ventilated membrane for medical treatment of the present utility model so just has waterproof and ventilative advantage, has solved the waterproof that existing medical film exists but breathability is poor, good permeability but waterproof difference problem; In use, the PTFE rete is contacted with human body skin, with substrate layer toward the outer side, substrate layer will produce static with medicated clothing or the windage of health so in use, and then to human body generation negative charge, and the nerve that the negative charge of trace can stimulate the people makes people's mental relaxation, joyful, and then to the mood that patient brings, so just help patient to get well.
Embodiment 2
As depicted in figs. 1 and 2, a kind of waterproof ventilated membrane for medical treatment comprises substrate layer 1, and described substrate layer 1 is provided with PTFE rete 2, and described PTFE rete 2 is compounded on the substrate layer 1 by the compound mode of hot pressing.
Described substrate layer 1 is the non-woven fabrics of every weight per square meter 60-80 gram.
The thickness of described PTFE rete 2 is the 0.5-2 millimeter.
This utility model is made up of substrate layer and the PTFE rete that is compounded on the substrate layer, the substrate layer good permeability, the PTFE rete has fibril shape microcellular structure, porosity is more than 85%, every square centimeter has 1,400,000,000 micropores, and but the micropore on the PTFE rete has characteristics ventilative the energy waterproof, a kind of waterproof ventilated membrane for medical treatment of the present utility model so just has waterproof and ventilative advantage, has solved the waterproof that existing medical film exists but breathability is poor, good permeability but waterproof difference problem; In use, the PTFE rete is contacted with human body skin, with substrate layer toward the outer side, and substrate layer is non-woven fabrics, and non-woven fabrics will produce static with medicated clothing or the windage of health so in use, and then human body is produced negative charge, and the nerve that the negative charge of trace can stimulate the people, make people's mental relaxation, joyful, and then to the mood that patient brings, so just help patient to get well.
