Description

A new type of contraceptive device Technical Field

[0001] This invention relates to the field of livelihood products, specifically to a novel contraceptive device. Background Technology

[0002] Currently, condoms used on the market consist of a condom body and a ring. When using a condom, the ring needs to be manipulated by hand to get the condom on the penis, resulting in complete coverage of the penis and preventing direct contact between the penis and the vaginal wall, thus reducing the pleasure.

[0003] To address the aforementioned issues, a new type of contraceptive device is proposed that is convenient to wear, hygienic, safe, and increases the contact area. Technical solutions

[0004] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned technology and provide a novel contraceptive device.

[0005] A novel contraceptive device includes a cannula, a protective cover, a collection bag, a collar, and a connecting line. The protective cover is located at the top of the cannula, the collection bag is connected to the cannula, the protective cover is located between the collection bag and the cannula, and the collar is connected to the protective cover via the connecting line.

[0006] The cannula, protective cover, and collar are all flexible.

[0007] The liquid collection bag is shrinkable;

[0008] The connecting line is flexible.

[0009] Furthermore, the connecting line is linear.

[0010] Furthermore, the bottom end of the cannula is provided with a smooth transition surface. Beneficial effects

[0011] Advantages of this invention: This invention has a reasonable structure, is convenient, safe and hygienic to wear. The protective cover and the ring are connected by a connecting line, which replaces the full-coverage design of existing ordinary condoms, greatly increases the contact area and improves the user experience.

[0012] The catheter effectively guides the flow of semen. It is in close contact with the vagina, ensuring a good seal and preventing semen from leaking out of the outer wall of the catheter. The smooth, curved surface at the rear end of the catheter effectively guides the semen, preventing leakage and improving contraceptive efficacy.

[0013] The protective shield prevents the collection bag from entering the penile urethra when the penis enters the vagina. Attached Figure Description

[0014] Figure 1 is a cross-sectional schematic diagram of a novel contraceptive device according to the present invention;

[0015] Figure 2 is a schematic diagram of the protective shield of a novel contraceptive device of the present invention.

[0017] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0018] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0019] In the description of the embodiments of the present invention, if a feature is referred to as "setting", "fixing", "connecting", or "installing" on another feature, it can be set, fixed, or connected directly to the other feature, or it can be set, fixed, connected, or installed indirectly on the other feature.

[0020] In the description of the embodiments of the present invention, the term "several" means one or more, and the term "multiple" means two or more. The terms "greater than," "less than," and "exceeding" should be understood as excluding the stated number, while the terms "above," "below," and "within" should be understood as including the stated number. The terms "first" and "second" should be understood as distinguishing technical features, and not as indicating or implying relative importance, or implicitly specifying the number of indicated technical features or the order of the indicated technical features.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.

[0022] A novel contraceptive device includes an insertion tube 1, a protective cover 2, a collection bag 3, a collar 4, and a connecting line 5. The protective cover 2 is located at the top of the insertion tube 1. The collection bag 3 is connected to the insertion tube 1. The protective cover 2 is located between the collection bag 3 and the insertion tube 1. The collar 4 is connected to the protective cover 2 via the connecting line 5.

[0023] The cannula 1, protective cover 2, and collar 4 are all flexible;

[0024] The liquid collection bag 3 is shrinkable;

[0025] The connecting line 5 is elastic.

[0026] The connecting line 5 is linear.

[0027] The bottom end of the cannula 1 of the present invention is provided with a smooth transition curved surface 6, that is, the bottom edge of the cannula 1 cannot have sharp corners, so as to ensure that when the cannula 1 is inserted into the urethra, it will not cause stinging pain or damage to the inner wall of the urethra.

[0028] The number of collars 4 in this invention can be increased, as shown in Figure 1, with four collars integrated. The combination of multiple collars ensures both secure wearing and comfortable wearing.

[0029] The protective cover 2 of the present invention only needs to cover the penile urethral opening and fits tightly to the periphery of the penile urethral opening, so that a large area of ​​the penile head is exposed, without completely covering the penile head, increasing the contact area between the penile head and the vagina, and improving the experience. As shown in Figure 2, when worn, the protective cover 2 can prevent the collection bag from entering the penile urethra when the penis enters the vagina.

[0030] When using this invention, the collar 4 is placed on the base of the penis, the insertion tube 1 is slowly inserted into the penile canal through the smooth transition curved surface 6, the protective cover 2 is placed tightly against the urethral opening of the glans penis, and the connecting line 5 between the collar 4 and the protective cover 2 is wrapped around the penis, thus completing the wearing process.

[0031] Semen flow direction: When semen is expelled, it enters the cannula 1 through the smooth transition curved surface 6 end of the cannula 1 and flows into the elastic collection bag 3.

[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0033] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
