Scheme two, described condom, comprise what an elastomeric material was made, the condom cylindrical shell that blind end and opening are arranged, blind end has sperm reservoir, also include an elastic sealing ring, the outer ring diameter of described sealing ring is greater than the barrel diameter of condom, and sealing ring and condom opening are connected as a single entity.
In such scheme one or the scheme two, described sealing ring can be a ring body that cavity is arranged, and also can be solid ring body.
Above-mentioned described condom, the internal diameter of described sealing ring is slightly smaller than the barrel diameter of condom, also can be not less than the barrel diameter of condom.
In the scheme one, the connected mode of described sealing ring and opening crimping can be by impregnation method, also can connect by bonding or other modes.In the scheme two, the connected mode of described sealing ring and cartridge openings end can be dipping, bonding or other modes.
The described condom of such scheme has following beneficial effect:
Described condom has to prevent that condom from dropping to intravaginal and preventing the technique effect of seminal fluid spill and leakage, has the contraception of raising success rate, prevents the sexually transmitted disease (STD) cross infection, the advantage that prevents AIDS.Condom of the present utility model has changed and has leaned on the condom port to be attached to the fixedly anticreep mode of penis in the prior art, but has been supported in the supporting traction mode at vaginal orifice place by the sealing ring of condom opening.The change of this mode has not only solved the problem that prevents that condom from coming off, and has solved the problem of seminal fluid spill and leakage simultaneously.The sealing ring external diameter is obviously greater than the penis diameter, and sealing ring plays the supporting traction effect to condom, condom can not take place come off into the phenomenon of vagina.When male ejaculation, radix penis part adds that to the sealing ring squeezing action sealing ring is the shutoff vaginal orifice comparatively closely under the containing contraction of vagina mouth to sealing ring, and seminal fluid can not flow out condom.The male ejaculation penis is soft contract after because the supporting role of sealing ring, the condom opening is in diastole state all the time, sealing ring is the shutoff vaginal orifice closely, even this moment, the condom opening had the part seminal fluid, can not flow into intravaginal yet, thereby prevent seminal fluid spill and leakage phenomenon.
Described condom has the custom of meeting, and is easy to use, makes simple advantage.
The same, easy to use during use with traditional condom mode, meet custom.Utility model people is on probation by experiment, the described condom that has sealing ring, and the sensation for the women does not only have any discomfort can also increase the massage stimulation to the vagina mouth.Described condom owing to just increased a sealing ring, does not change other manufacturing parameter and condition of condom, makes simply, is easy to realize the mechanization operation, enhances productivity.
What deserves to be mentioned is that this utility model has overcome people use is had the sealing ring condom, think uncomfortable or the prejudice of foreign body sensation is arranged.
