Description

Safety condom

Technical field

This utility model relates to a kind of family planning apparatus, specifically, is a kind of condom.

Background technology

Condom is easy to use, can not only practise contraception, and can also play the effect of preventative disease and acquired immune deficiency syndrome (AIDS) simultaneously.The tradition condom is in use because its opening collar (crimping) is not enough to play support and sealing function, thereby in sexual life, easily produce condom and drop to phenomenon in the vagina, perhaps seminal fluid overflow phenomena, its result not only can make wife's side accidental pregnancy, and the chance of increasing property cross infection of disease easily; On the other hand, even selected suitable condom, and by the correct method use, but because ejaculation back the soft of penis contracts, condom still has and drops to the danger that reaches the seminal fluid spill and leakage in the vagina.In order to overcome condom above-mentioned defective in use, people have done many improvement when making condom, are that barrel diameter with condom is extended to and can contains scrotum down as the technical scheme of Chinese patent CN1317300A; Then be to adopt on former opening has the basis of the collar (crimping), to increase one or more ring again and strengthen and support and sealing function among the U.S. Pat 5715839A.Though these new condoms have solved the invention task, all ignored most of people's use habit and applied mental, the former condom has not existed the comfort of male in sexual life; And latter's dicyclo or polycyclic condom make men and women feel uneasy, uncomfortable equally in sexual life, and can produce the psychology of foreign body sensation.

The utility model content

Technical problem to be solved in the utility model is, a kind of use habit that can meet people is provided, and can effectively prevent to come off again and seminal fluid spill and leakage and make simple safety condom.

For achieving the above object, technical solution adopted in the utility model is: a kind of safety condom, constitute by an elastic cylinder that comprises opening and blind end, and described opening is provided with crimping, and described blind end is provided with sperm reservoir; This elastic cylinder is being divided into the extension cylindrical shell and is not extending cylindrical shell two parts with respect to the radix penis part position, the length of described extension cylindrical shell is not extend 1～2 times of length of cylindrical shell, and this extension cylindrical shell is stacked to relative radix penis part position from the crimping volume of opening and constitutes one and support sealing ring.

Compare with the condom of background technology, this utility model is owing to taked to increase considerably the measure of exntension tubs body length, make it be stacked to relative radix penis part position and form a support sealing ring naturally from opening crimping volume, this support sealing ring is owing to be folded the forming of extension cylindrical shell volume of sufficient length, quantitative change has produced qualitative change, and its support degree is very strong, is equivalent to dicyclo or the effect of going back more, therefore, sealing function is also outstanding manifests; In the use, this external diameter that supports sealing ring is obviously greater than the diameter of erection penis, under the dual function of radix penis part to its extruding and the contraction of vagina mouth, penis soft contracting whether no matter, this support sealing ring remains expansion state and is in outside the vagina mouth, has prevented effectively that therefore it from coming off and the extremely intravaginal danger of seminal fluid spill and leakage; On the other hand, this utility model is easy to use, meet custom, promptly the using method with traditional condom is the same, condom is placed on the penis, and exhibition is put to root of penis portion, and exhibition is not put part (yet promptly extending cylindrical shell) and formed the support sealing ring naturally at radix penis part, during sexual life, because of need not scrotum is encased, therefore do not influence men and women's comfort, overcome people simultaneously and be with the psychology of foreign body sensation using the sealing ring contraception.

In technique scheme, described extension cylindrical shell with do not extend cylindrical shell and be generally the equal diameter cylindrical shell, as a kind of improvement of the present utility model, also can make the reducing cylindrical shell, the diameter that promptly extends cylindrical shell is a bit larger tham or is slightly smaller than the diameter that does not extend cylindrical shell.

If greater than situation, its beneficial effect is except that the above, owing to extend cylindrical shell at obvious more the diameter of the external diameter of the relative formed support sealing ring of radix penis part greater than the erection penis, the slip-off preventing better effects if, the vagina mouth is massaged stimulation in addition, and its internal diameter and non-tight contact of radix penis part have reduced the sensation that male penis is fettered by transition;

If less than situation, its beneficial effect owing to extend cylindrical shell at the internal diameter of the formed support sealing ring of the radix penis part relatively diameter less than the erection penis, and has the constraint effect to it except that the above, therefore has the penile blood of slowing down back-flow velocity, the effect that prolongs sex time.

This utility model is compared with the condom of prior art, also has to make the advantage simple, that cost is low, promptly needn't change technological parameter and condition, needn't increase special installation, gets final product by traditional condom manufacture.
