Description
【Technical field】
The present invention relates to sheath more particularly to a kind of sheaths and its manufacturing method containing nanometer materials.
【Background technology】
The preparation method of presently commercially available sheath is mostly based on homogenous material and single impregnation technology.Whether latex, poly-
Isoprene, polyurethane or silica gel, the aperture between these high molecular material groups is big, and porosity is high, there is from it is hundreds of very
To the natural void between thousands of nanometers.Large-sized wide about 3000 nanometers of the human sperm in such as head is being obstructed, that is,
It is significantly effective when contraception.But the smaller virus of grain size in obstructing body fluid, such as 42 nanometers of diameter B-type hepatitis
Poison, 50~55 nanometers of human papillomavirus, 120 nanometers of AIDS virus or even smaller particle virus when, just less
Guarantor leans on.The Testing Guidance for Male Condoms Made from New promulgated according to U.S. FDA
The 27 nanometer diameter virus breakthrough experiment of pressurized conditions Imitating listed in Material (June 29,1995) the result shows that,
Latex, polyisoprene, polyurethane, silica gel material sheath all can by 27 nanometer diameters virus penetrate.Even if so
In the case of normal and proper use of ordinary condom, there are still the risks that passability contact catches with body fluid contamination.
【Invention content】
In order to reduce the probability that certain nano level viruses pass through, the present invention provides a kind of contraceptions containing nanometer materials
Set and its manufacturing method.
A kind of manufacturing method of the sheath containing nanometer materials, includes the following steps：
Sheath matrix is placed in plasma environment and pre-processes by S1；
S2 forms the fluoride of one layer of Nano Particle on the surface of the sheath matrix.
In one embodiment,
In the step S2, the fluoride is formed in the outer surface of the sheath matrix；
Further include following steps upon step s 2：
S3 carries out shaping the sheath matrix with fluoride at a temperature of 100 DEG C to 200 DEG C, forms contraception
Set；
S4 cleans the sheath using ultrasound.
In one embodiment,
The fluoride is polytetrafluoroethylene (PTFE).
In one embodiment,
The molecular weight of the polytetrafluoroethylene (PTFE) is no more than 100,000 grades of molecular weight.
The present invention also provides a kind of sheaths using containing nanometer materials made from the manufacturing method, including keep away
The fluoride of one layer of Nano Particle is adhered on pregnant set matrix, the surface of the sheath matrix.
In one embodiment,
The fluoride is formed in the outer surface of the sheath matrix.
In one embodiment,
The thickness of the fluoride is between 0.1 to 1000000 nanometer.
In one embodiment,
The material of the sheath matrix is latex, polyisoprene, polyurethane or silica gel.
In one embodiment,
Along the radial direction of the sheath matrix, band-like annulus is equipped on the inside or outside of the sheath matrix, it is multiple
The band-like annulus is arranged along the length direction of the sheath matrix.
In one embodiment,
In the open end periphery of the sheath matrix there is stop member, the stop member to be erected in sheath matrix
Outer surface, the thickness of the stop member gradually successively decreases along the inside of the sheath matrix to outer direction.
The beneficial effects of the invention are as follows：
Pretreatment is carried out to sheath basis material after molding with plasma and surface is modified, fluoride can be improved
The conjugation of layer and base material.
The fluoride preferably polytetrafluoroethylene PTFE, because polytetrafluoroethylene PTFE has corrosion resistance, physiology lazy
Property and high-lubricity, be suitble to contact with human body mucous membrane in addition as medical instrument part implantation human body and have no adverse reaction.
It is preferred that relative molecular weight is smaller, for example, 100,000 grades of molecular weight polytetrafluoroethylene PTFE material, such manufactured goods
Aperture is small, can obstruct the virus of tens nanometer diameter.The friction coefficient of polytetrafluoroethylene (PTFE) is only 0.04, and high-lubricity makes do not have
It is necessary to physiology lubricating oil is added especially on body.
The temperature of high-temperature shaping is between 50 DEG C to 350 DEG C, preferably between 100 DEG C to 200 DEG C.Excessively high temperature may be led
It causes polytetrafluoroethylene PTFE cracking and generates noxious material.
The thickness of fluoride layer ensure that its elasticity and pliability, otherwise blocked up that body can be caused to lose elasticity and softness
Degree.
The contamination that body fluid can further be completely cut off perpendicular to the stop member of body, keeps both sides safer.
There are multiple band-like annulus along body vertical direction in the front-back direction, at least on the inside of open end and in the middle part of body
Side has band-like annulus.The internal diameter of the inside band-like annulus in body root and middle part is more smaller than penis outer diameter, to dorsal nerve of penis
Applying the external force slightly tightened influences, and the cerebripetal transmission of delay exciting signal reduces the sensibility of dorsal nerve of penis, improves
Ejaculation stimulus threshold achievees the purpose that the prolonging sexual action time to extend ejaculation latency, so band-like annulus is also named delay
Ring.In addition, the annulus in the middle part of body can also be after the overturning doubling of set inside and outside, the starting axis as wound body.
Within the preferred 140mm of maximum gauge of the outer of peltate annulus, sufficient shadowing effect can be provided, it is long then
Peltate annulus is caused to be difficult to be erected in the outside of sheath matrix.The thickness of the peltate annulus is along the inside of body to outer
Gradually successively decrease in direction so that peltate annulus is erected on the sheath matrix more to be stablized.
【Specific implementation mode】
The following further describes in detail the preferred embodiments of the invention.
Sheath includes men's and female condom.It is mostly leading with male in view of sexual behaviour, in the market with condom
Based on.As typical case, following embodiment refers to condom for man, unless it is that women is kept away that, which there is special explanation in certain places,
Pregnant set.
A kind of manufacturing method of the sheath containing nanometer materials of embodiment, includes the following steps：
S1 is placed in plasma environment sheath matrix, and plasma is made to be come into full contact with sheath matrix, to
Sheath matrix is pre-processed.
The material of sheath matrix after molding is subjected to plasma pretreatment and surface is modified, so as to improve fluorine
The conjugation of compound and the material of sheath matrix.
S2 forms the fluoride of one layer of Nano Particle on the surface of the sheath matrix.
The method for forming one layer of fluoride with Nano Particle can in the plating of the surface of sheath matrix or be covered with
