Abstract

Abstract A new concept of pregnancy and disease prevention is provided by a medicated tampon in the form of a soft, porous foam ball, which is easily insertable into the vagina to cover the cervical area and which is impregnated with a safe spectrum of antibiotics for control of venereal disease and with a contraceptive for control of pregnancy. The tampon may be inserted before intercourse to remain in place during intercourse.

Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 105 words
A moist medicated vaginal tampon for contraceptive and venereal disease control comprising a soft, porous foam ball of substantially spherical configuration in the uncompressed state and of a size and compressibility to fit snugly within the vagina of a human female to cover the cervix area while permitting intercourse to take place, said spherical configuration permitting easy insertion without the necessity of orientation, said porous foam ball being impregnated with a solution containing an amount of an antibiotic selected from the group consisting of salts of bacitracin, neomycin, polymyxin B and mixtures thereof effective to control venereal disease and a contraceptively effective amount of nonoxynol.
Claim 2
Dependent Claim 105 words
A moist medicated vaginal tampon for contraceptive and venereal disease control comprising a soft, porous foam ball of substantially spherical configuration in the uncompressed state and of a size and compressibility to fit snugly within the vagina of a human female to cover the cervix area while permitting intercourse to take place, said spherical configuration permitting easy insertion without the necessity of orientation, said porous foam ball being impregnated with a solution containing an amount of an antibiotic selected from the group consisting of salts of bacitracin, neomycin, polymyxin B and mixtures thereof effective to control venereal disease and a contraceptively effective amount of nonoxynol.
Claim 3
Dependent Claim 32 words
The vaginal tampon as defined in claim 1, wherein the shape is a foam ball of a soft, foamed material selected from the group consisting of polyurethanes, polyesters, polyethers and mixtures thereof.
Claim 4
Dependent Claim 21 words
The vaginal tampon as defined in claim 1, wherein the antibiotic agent comprises zinc bacitracin, neomycin sulphate and polymyxin B sulphate.
Claim 5
Dependent Claim 25 words
The vaginal tampon as defined in claim 1, wherein the impregnating solution comprises a mixture of water and glycerin containing said antibiotic and contraceptive agents.
Claim 6
Dependent Claim 21 words
The vaginal tampon as defined in claim 1, wherein the impregnating solution is buffered to a pH value of about 4.5.
Claim 7
Dependent Claim 18 words
The vaginal tampon as defined in claim 1, wherein the foam ball has a diameter of about 15/8".
Claim 8
Dependent Claim 18 words
The vaginal tampon as defined in claim 1, wherein the solution comprises about 10% by weight of nonoxynol.
Claim 9
Dependent Claim 32 words
The vaginal tampon as defined in claim 1, which further comprises a string connected to the shape of porous material adapted for easy removal of the tampon from its site of application.
Claim 10
Dependent Claim 17 words
The vaginal tampon as defined in claim 1, which is contained singly in a moisture proof package.
Claim 11
Dependent Claim 38 words
A method for preventing pregnancy which comprises the step of applying to the vaginal cavity of a mammalian female the vaginal tampon as defined in claim 1 precoitus and retaining it in the vaginal cavity during sexual intercourse.
Claim 12
Dependent Claim 39 words
A method for contraceptive and venereal disease control which comprises the step of applying to the vaginal cavity of a human female the vaginal tampon as defined in claim 18 and retaining it in the vaginal cavity during intercourse.
Claim 13
Dependent Claim 121 words
A moist medicated vaginal tampon for contraceptive and veneral disease control comprising a porous foam ball of substantially spherical shape adapted to be inserted into the vagina prior to sexual intercourse without the necessity of an applicator and to be retained in the vagina during such intercourse, said ball being of a soft, light weight foam material having a very fine porosity and being impregnated with a solution of water and glycerin containing per ounce the following antibiotics in approximately the amounts specified, 12,000 units of zinc bacitracin, 85 mgm. of neomycin sulphate, 250,000 units of polymycin B sulphate, together with the spermicide nonoxynol in 10% concentration in the solution, and said solution being buffered to a pH of approximately 4.5.
Claim 14
Dependent Claim 121 words
A moist medicated vaginal tampon for contraceptive and veneral disease control comprising a porous foam ball of substantially spherical shape adapted to be inserted into the vagina prior to sexual intercourse without the necessity of an applicator and to be retained in the vagina during such intercourse, said ball being of a soft, light weight foam material having a very fine porosity and being impregnated with a solution of water and glycerin containing per ounce the following antibiotics in approximately the amounts specified, 12,000 units of zinc bacitracin, 85 mgm. of neomycin sulphate, 250,000 units of polymycin B sulphate, together with the spermicide nonoxynol in 10% concentration in the solution, and said solution being buffered to a pH of approximately 4.5.
Claim 15
Dependent Claim 38 words
A method for preventing pregnancy which comprises the step of applying to the vaginal cavity of a mammalian female the vaginal tampon as defined in claim 12 precoitus and retaining it in the vaginal cavity during sexual intercourse.
Claim 16
Dependent Claim 81 words
A moist, medicated vaginal tampon for contraceptive and venereal disease control, comprising a shape of physiologically inert, soft, porous, light weight foam material which is insertable in the vagina prior to intercourse without the necessity of an applicator, said shape being impregnated with a solution comprising per one ounce about 12,000 units of zinc bacitracin, 85 mgm. of neomycin sulphate and 250,000 units of polymyxin B sulphate for venereal disease control and with a contraceptively effective amount of a contraceptive agent.
Claim 17
Dependent Claim 81 words
A moist, medicated vaginal tampon for contraceptive and venereal disease control, comprising a shape of physiologically inert, soft, porous, light weight foam material which is insertable in the vagina prior to intercourse without the necessity of an applicator, said shape being impregnated with a solution comprising per one ounce about 12,000 units of zinc bacitracin, 85 mgm. of neomycin sulphate and 250,000 units of polymyxin B sulphate for venereal disease control and with a contraceptively effective amount of a contraceptive agent.
