Patented Oct. 27, 1970 Sheet HUMAN BIRTH CONTROL APPLIANCE Its primary aim and practical application is fundamentally designed for use in cases where pregnancies follow too soon one after the other and which require to be restricted or avoided for reasons of health. as well as in cases where pregnancy is desired to be guided, planned or controlled for economic reasons as in over-populated areas of the world where voluntary population control programs are in operation.

CONTRACEPTIVES THEIR PRESENT STANDING AND UTILITY SHORTCOMINGS AND DEFICIENCIES The shortcomings and deficiencies of existing contraceptives can be easily traced and described. For example, in the case of the contraceptive appliance for women commonly known as a pessary, comprising a rubber cap or cover to be inserted by hand and fitted over the mouth of the uterus, there is in rtself a distinct lack of utility and perfection because of its liability to slip off the uterus during intercourse and because of its discomfort and danger in causing likely hurt to the uterus, if fitted too tightly in an attempt to prevent it from slipping. Also, like almost every other known intrauterine device that has to be inserted by a physician or highly trained nursetechnician so that it is not pushed through the wall of the uterus, the pessary entails an adverse and unpleasant manner of application by hand which is in itself an undesirable encroachment on individual privacy since it requires to be usually inserted in the first instance by a medically qualified person or gynaecologist in order to demonstrate its use. At the same time, its long period of inner retention creates an additional handicap for its user in maintaining general hygiene. cleanliness, well-being and comfort. Therefore, on account of the pessarys uncertain ability to remain comfortably lodged over the mouth of the uterus, particularly during intercourse. the actual purpose of its function becomes wholly defeated and it can not claim true security against conception. Furthermore, in common with every other known type of intrauterine device irrespective of whether it is the loop, the condom or a diaphragm, the pessary also offers no protection whatsoever against venereal infection by means of the genitals, apart from its unreliable use as a so called contraceptive.

Similarly in the case of the contraceptive used by men, commonly known as a rubber prophylactic or sheath to be fitted and stretched over the male organ. there is again no true surety and safety against conception nor does it offer any true safeguard against venereal infection. By its very compulsion in having to remain stretched, taut and expanded all the time during coitus-thereby increasing its breakage hazard as compared to unstretched. untaut and unexpanded rubber-its elastic capacity is jeopardised and it becomes liable to burst or tear during use. Consequently, it is no longer risk-free.

Also, due to its constantly stretched, taut and-expanded dissatisfaction in sensitivity to the user, because it constantly Another method for contraception, expediently used nowadays by some women, consists in taking so called oral contraceptives commonly known as the pill" in order to produce ovulation restraints each and every month. This process offers even less satisfaction and more risk than its already described counterparts. In its attempt to negate nature with the aid of chemical compounds whereby the normal birth process in the human female is disturbed by means of biological conversions and hormonal interferences so that the fertilizable egg from a womans ovaries is prevented from fulfilling its monthly cyclic release, it is not surprising to find that, like most medicines, the pills produce incidental effects. Experience has shown that the most common complaints are gain in weight (ironically a condition which most women prefer to avoid), nausea, breast tenderness and break-through bleeding combined with the risk of falling pregnant if a woman has skipped a pill or two, or even if she may sometimes change her brand of pills.

Added to this list of disturbing and alarming disadvantages, the Medical Council in Britain recently reported the risk of thromboembolic disorders and vascular complications from the use of the pill. It is, therefore, not (llffiCUIt' to understand why only 24 percent of American women make use of the pill or so called oral contraceptives. The final prognosis of the effect of these compounds and their chemical reaction in the human body-either good or bad-still remains controversial and can not be generalized. Despite having come into general use since l96l, many medical practitioners have been concemed about their safety and any valid conclusion must await accurate data on a much larger group studied for at least l0 years or more.

Thus, the true evaluation of oral contraceptives and what further possible risk or long-range side effects may be discovered in the future by users of any chemical compounds- -irrespective of whether they are to be taken before or after intercourse-is not yet discemable nor ascertainable. The whole issue is tied up with the factor of time, extending perhaps into many years, to determine if even future off-spring is free from any detrimental after effects as the direct result of oral contraceptive methods practiced one or two generations ago.

MY INVENTION My invention is, therefore, an appliance which overcomes and removes the deficiencies and shortcomings of all hitherto used contraceptives. Briefly. the new appliance is simply a mechanical barrier between the human genitals. It is dual in its function and serves both man and woman simultaneously. Also, both use it at one and the same time and in conjunction with each other.

DRAWINGS The attached drawings show, for illustration only, my invention and its style of use and application.

FIG. 1 is a front view of the dual contraceptive appliance showing its novel characteristic and distinguishing feature, the embodied and reversible proboscis,b, in its resting position before use.

condition during use, the said common prophylactic creates grips the male organ and constantly presses against innumera- I ble tiny super sensitive glands situated around and below the penis head which impairs their function in- -'s ensitivity and causes a sense of frustration and dissatisfaction to the user. Therefore, here again there is lack of perfection and safety so that the common prophylactic used by men is not only unsatisfactory in regard to human sensitivity and feeling, but also not fully safe in its use as a contraceptive.

FIGS. 36.;are enlfirged views of the base and top of the embodied and reversible proboscis, b, showing both the outside and the inside of its bellowslike folds, c, in their extended position. i

FIG. 7 is a cross section, viewed from above, showing half of the dual contraceptive appliance with its embodied and reversible proboscis, b, in its extended position and the opening, d, for the insertion of the leg when the appliance, FIG. 1, is worn by the user.

DESCRIPTION NOVEL CHARACI'ERISTIC AND DISTINGUISHING FEATURES The dual contraceptive appliance, FIG. 1, comprises a single one-piece unit, a, without any straps, tapes, press buttons, snap fasteners or other auxiliary tying or holding devices and in the overall shape of a panty, styled and fashioned like a popular bikini, to be worn during coitus by the woman, next to the skin and lower part of the body, and made from well known membraneous and transparent elastic or dermal thickness in the highest degree of strength, viscosity and expansion ratio. Its novel characteristic and distinguishing feature, whereby its duality is established, is an integrant and reversible cul-de-sac proboscis, b, disposed in the center at the crotch of the said appliance, and having circular shaped bellowslike folds, c, throughout its length, which remain folded before coitus when the said proboscis is in its resting postion, FIG. 1, and which unfold, stretch and extend during coitus when the said proboscis is in extended position, FIG. 2.

NOVELTY AND UTILITY During coitus, when the said dual contraceptive appliance, FIG. I, is worn by the woman, the penetration act of the male organ pushes the said proboscis, disposed in the center and at the crotch of the said appliance, FIG. I, into the vagina, whereby both enter the vagina passage together and wherein the male organ automatically covers itself with. the said proboscis which unfolds and becomes extended, FIG. 2. By this means a mechanical barrier is established between the respective human genitals and in this manner both man and woman use the said dual contraceptive appliance simultaneously and in conjunction with each other, whereby their genitals are fully protected and totally prevented from making any dermic contact with each other and whereby no human conception is physically possible.

At the same time by means of the said circular shaped bellowslike folds, c, throughout the length of the said proboscis,

there is freedom of movement within for the male organ whereby no grip, seizure of pressure is exercised against itssuper sensitive glands to impair their sensitivity and cause dissatisfaction or fnistration in feeling. Also, the said folds of the said proboscis physically provide much greater elastic stretch, expansion and extension ratio than that offered by plain tubular elastic without such folds, so that a point of limited elasticity can never by reached during intercourse and whereby no risk of breakage can ever arise at the time of coitus.

Therefore, by means of using during intercourse the aforementioned new and unique dual contraceptive appliance with reversible proboscis, the risk of undertaking any subsequent termination of pregnancy or abortioneither by pharmaceutical means or by surgery-is completely eliminated and human conception can be truly guided, planned or controlled with positive surety and without any fear of conception; without any fear of a breakage hazard; without any fear of interfering with the normal birth process of the human female; without any fear of creating ovulation restraints each month so as to cause eventual thromboembolic disorders; without any fear of vascular complications or other incidental effects which may prove detrimental to a woman's health; without any fear of diminishing or disturbing human physical sensitivity and without fear of harm to human health and well-being.


l. A dual contraceptive appliance comprising a single onepiece membraneous elastic unit in the overall shape and design of a garment closely akin to a bikini-styled panty, and having front and back sections joined together with leg openings through the bottom thereof as well as having an opening at the top thereof for engagement with the torso during wear, said panty also having a crotch portion with an integrant and reversible cul-de-sac proboscis which has circular shaped bellowslike folds throughout its length and said proboscis being transversely disposed at the center of said crotch portion for engagement with the genitals during use.
