Abstract

Lubricating gel compositions manufactured from water-soluble polymers and distilled water can prevent not only pregnancy but also sexually transmitted diseases (STDs) including AIDS due to their roles as physical blocking walls and spermicides. Colloidal silver, which has germicidal effects in a wide range, can be added to these compositions. These lubricating gel compositions, which are harmless and non-irritating to the male urethra, can be called ''Urethral Condoms'' because they act like condoms when injected into male urethras, and are easily eliminated from urethras by urination. They can also be called ''Liquid Female Condoms'' because they act like female condoms when injected into vaginas, and are easily eliminated from vaginas by vaginal irrigators and the vaginal scrubbing sponge of this invention.

Description

Urethral condoms and liquid femidoms

[technical field]

The present invention relates to can be used for lubricant (lubricating gel) complex and apparatus during the sexual intercourse, wherein these lubricant composites not only also can be used as antibacterial and spermicide to the effect that pathogenic bacteria and sperm play the physical barrier wall.Therefore, these fluid products can prevent to comprise the STD (sexually transmitted disease (STD)) and the pregnancy of AIDS (acquired immunity deficiency syndrome) as condom and contraceptive diaphragm.

[background technology]

1. present, Nonoxynol-9 is the most widely used spermicide that is used to practise contraception.But because its chemical toxicity, it can cause highstrung male urethra stimulates and pain.Also knownly when using overfrequency, also may cause colpitis and ulcer.Though have been found that many other spermicides, not to the complete harmless spermicide of human body such as octoxynol 9, menfegol and suramin.This is that this scope is harmful too so because if the toxicity of spermicide is enough killed sperm.

At present, the best method that prevents various STD and AIDS is to use condom, plays the effect of physical barrier wall between pathogenic bacteria and human body epithelial tissue.But, condom detests the use condom because having reduced the therefore common people of the impression of property.On the contrary, the impression that lubricant can increasing property.But only use common lubricant to be helpless to prevent STD and AIDS.Therefore, many lubricants that contain chemical bactericide have been developed for the purpose that prevents STD and AIDS.For example, developed the lubricant that contains such as the antibacterial of sulfuration diazine silver (silversulfurdiazine), chlorination six pyridine gluconates (chlorohexidine gluconate), zinc gluconate, sodium lauryl sulphate and dextrin sulfate.Yet because these antibacterial may cause pain and stimulation to extremely responsive male urethra, they can not inject the male urethra that is subject to microorganism encroach responsive or the most unique for the male.Therefore, these antibacterial only can use in the urethra outside, and this will reduce their effectiveness.

Known collargol (colloidal silver) can kill the antibacterial and the virus that may cause disease more than 650 kinds in several minutes.Recently, can utilize the collargol that makes 2-15nm size and 1-10ppm concentration greater than the silver electrode of 99.99% purity in the distilled water electrolysis simply.

2. present, the catheter of being made by long and thin rubber pipe must insert in the male urethra very darkly and liquid chemical agent could be injected male urethra, prostate and bladder, these organs are diagnosed and treated.Yet, because inserting extremely responsive urethra, solid tube will cause violent pain, most of people detest this mode very much.Up to the present, other apparatuses or method can be injected male urethra with liquid very darkly in the absence of not inserting solid tube.

3. present, most popular vaginal douche constitutes by forming collinear elastic bottle (elastic bottle) and spray nozzle.Because the people must be in the bit position of standing or squat when using, use also uncomfortable.And because cleaning mixture is sprayed up when spray nozzle inserts vagina, at this moment gas usually sprays rather than cleaning mixture from elastic bottle, uses very inconvenient.Last because the cleaning mixture that hands may be easy to be overflowed is got wet, use also pretty troublesome.

[summary of the invention]

[technical problem]

1. develop a kind of lubricant composite, it can form the isolated pathogenic bacteria of similar contraceptive cover and the physical barrier wall of sperm at the human body epithelial tissue, plays the effect of antibacterial and spermicide, and harmless and non-stimulated to male urethra.

2. develop a kind of fluid injector that injects male urethra, it will not cause any pain of male urethra.

3. develop a kind of vaginal douche, it can be sitting on the lavatory seat and use very comfily, can not spray air rather than water, and water can not spilt on hand.

[technical scheme]

The inventor has solved the technical problem of above-mentioned proposition, and is as follows:

1. prevent the lubricant composite of conceived and STD:

The inventor finds that " distilled water is excellent spermicide to a surprising fact! ".By obtaining experimentally confirmation with the observation by light microscope sperm mixing the back with distilled water, explain by this available in theory osmotic shock by the inventor for this fact.

The inventor finds that also " the water-soluble polymer molecule can form the physical barrier wall that is difficult to pass through to pathogenic bacteria and sperm to another surprising fact on the human body epithelial tissue in addition! ".This fact is confirmed that it in theory also can followingly make an explanation by the inventor indirectly in the following clinical trial that illustrates 1 and 2:

Plain derivant such as the sodium carboxymethyl cellulose (SCMC) of known fiber, hydroxyethyl-cellulose (HEC) and hydroxypropyl emthylcellulose (HPMC) are wherein safest water-soluble polymers, its can be on their chain in aqueous solution load anion and polarity.Therefore, as shown in Figure 1, these polymer molecules are easy to adsorb and form the physical barrier wall between load on their the surface protein molecule are by cation and polar human body epithelial tissue and microorganism.In addition, it is 10-20nm that equispaced between the polymer chain in these aqueous solutions is estimated, (human immunodeficiency virus, the average-size of diameter=125nm) is much smaller than HIV.Therefore, almost all pathogenic microorganism can not penetrate these intensive physical barrier walls easily and stick on the human body epithelial tissue.This situation be similar on the meadow ball since very thick and intensive lawn can't kiss the earth situation.It only is the physical characteristic that the ling-chain ion polymer molecule may have this uniqueness.

Therefore, the lubricant composite that is made by water-soluble polymer and distilled water not only can form the physical isolation wall on the human body epithelial tissue, also have the spermicide effect.In order further to improve the prevention effects that they resist STD, also can add collargol with broad-spectrum bactericidal action.The inventor finds that collargol does not cause any stimulation to male urethra.

In fact, of the present inventionly also can be effective to be injected in the male urethra, be subjected to the urothelial tissue of microorganism encroach with protection the most easily or separately the non-stimulated lubricant composite of male urethra.This as shown in Figure 3 available fluid injector of the present invention is realized.Therefore, because these fluid products play the effect of the condom of urethra, they also can be called as " urethral condoms ".Same, the lubricant composite that injects vagina can be called as " liquid femidoms ".Urethral condoms can be gone out by urinating easily, and liquid femidoms can be gone out by the vaginal douche of the present invention shown in Fig. 4-7.In addition, these lubricant composites also can be used for more playing a protective role of wide spectrum than condom or contraceptive diaphragm, because they can be applied to genitals and anal at an easy rate, go up or on every side.

1: one unmarried man of middle age of clinical trial tests about 90 times with urethral condoms and about 50 women, and the average probability report that its STD infects is 36.4%.By injecting 2ml lubricant composite of the present invention (not having collargol) and apply lubricant composite on its Glans penis in each its urethra of sexual intercourse forward direction, he does not infect STD, even once all do not have.

2: one 25 years old single womans of clinical trial, menstrual cycle is irregular, and the experience that artificial abortion was arranged, by before each sexual intercourse, 12ml lubricant composite of the present invention (not having collargol) being injected its vagina also afterwards with portable vaginal douche flushing of the present invention, successfully contraception in 16 months.

2. to the fluid injector of male urethra injection:

Shown in Fig. 2 and 3, the shape of injection nozzle (1) is that radius is respectively half elliptic (shape of rugby) or the proximate with it shape of 4-9mm, 5-12mm and 10-30mm, and is much bigger than the radius of urethra outlet.Injection nozzle is thinner than the urethra outlet on one side, on one side thicker than the urethra outlet.Therefore, when thin end of nozzle inserted male urethra, it only was that part enters male urethra.When exporting the nozzle of slight pressing part insertion in the other direction towards urethra, the slit between urethra outlet and the nozzle can seal fully.Subsequently, lentamente liquid is injected male urethra by the piston of pushing syringe.Urethra becomes full state (9) from flat state (7).If injection continues, the liquid of injection (10) can arrive prostate and bladder.The similar folding pipe of also available and dentifrice tube replaces syringe as pressure generator.

3. vaginal douche:

Fig. 4 shows the prototype of portable vaginal douche.It is made up of the long spray nozzle neck (2) that is connected with bottle cap of elastic bottle (1), 10-40cm and the long nozzle (3) of 1-5cm of cylindrical or truncated cone shape or both combinations.Fig. 5 shows the vaginal douche in the use when spray nozzle inserts vagina.The spray nozzle neck in the straight back that has kept 1-6cm along the crooked consumingly 60-120 degree of the shape of introitus vaginae.Subsequently, it is once more along abdominal part crooked smoothly 10-60 degree on same direction.Thereafter, its crooked smoothly in the opposite direction 10-60 degree is so that the operation of irrigator is more convenient.As shown in Figure 4, spray nozzle and spray nozzle neck one time-out look and have looked like to raise the Naja of head.Hand-held elastic bottle can easily find introitus vaginae by the contact of spray nozzle and spray nozzle is inserted in the vagina.When spray nozzle is in the vagina, can be easily by coming washing vagina up hill and dale before and after the mobile spray nozzle.Since spray nozzle neck (2) along the shape of introitus vaginae crooked consumingly the 60-120 degree, prevent that spray nozzle (3) from inserting in the vagina too far.Be different from existing portable irrigator, before using up whole flushing liquors, can not spray air.At this moment because elastic bottle is inverted, flushing liquor accumulates in the exit of bottle.Shown in Fig. 6 and 7, the spray nozzle neck can replace elastic bottle to be connected on the water pipe with flexible pipe and pressure-control valve.
