Abstract
Description
Technical Field
[0001] This invention relates to a medical device, and more particularly to a pre-installed safety bag for women. Background Technology
[0002] Condoms are a commonly used family planning product, primarily used to prevent sexually transmitted infections and unintended pregnancies. Existing condoms are generally simple, thin latex sheaths. They are convenient to use. Their main disadvantages are reduced tactile / thermal sensation and a tendency to slip / leak. This sensory problem arises from the thickness of the condom and its tightness around the penis; slippage / leakage occurs when the penis is sufficiently swollen to maintain the condom's stretch. During intercourse, the male's thrusting is blocked by the condom, preventing stimulation of nerve endings on the penis surface and thus eliminating sexual pleasure. This leaves men feeling helpless and extremely dissatisfied. However, due to contraception or the need to prevent viral infections, men are often forced to use them, causing deep, hidden psychological harm. Consequently, some men refuse to use them for various "reasons," leading to frequent unintended pregnancies and even the spread of various sexually transmitted diseases, severely damaging the physical and mental health of their partners, family harmony, and even causing social harm. To eliminate the psychological harm to men and greatly improve the quality of experience, inventing a pre-installed female condom would be highly beneficial. Summary of the Invention
[0003] The purpose of this invention is to address the shortcomings of existing condoms by providing a pre-installed female condom that can give women a feeling of fullness and strong stimulation to their sensitive areas, thereby enhancing sexual pleasure for men.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: it includes an oral ring (1), a telescopic membrane (2) connected to the lower part of the oral ring (1), a guide connecting sleeve (8) connected to the lower part of the telescopic membrane (2), the guide connecting sleeve (8) connected to an anti-detachment component (9), and a liquid-holding bag (10) connected to the lower part of the anti-detachment component (9). The oral ring (1) is a silicone ring containing an elastic stainless steel ring, with an open membrane (12) in the middle, a micro-slit (15) in the middle of the open membrane (12), a U-shaped annular groove (7) between the telescopic membrane (2) and the guide connecting sleeve (8), expansion and contraction membrane strips (6) evenly spaced on the U-shaped annular groove (7), and massage protrusions (3) on the telescopic membrane (2).
[0005] A preferred technical solution of the present invention is as follows: the anti-detachment component (9) is provided with a one-way swing side ear (14), the one-way swing side ear (14) is a component wrapped with a plastic strip, and the plastic strip component has a notch (16). The lower part of the mouth ring (1) is connected to the one-way swing side ear (14) by a pull strap (5). The stretch membrane (2) is provided with hemispherical silicone particles (4).
[0006] This invention utilizes a safety bag with a U-shaped groove and a micro-slit opening membrane whose aperture is smaller than the outer diameter of the user's penis. When the penis is inserted into the micro-slit opening membrane and passes through the U-shaped annular groove into the guide connecting sleeve, the natural tensile strength of the silicone creates a tightening force around the penis, giving the user a feeling of tightness. Upon further insertion, the glans penis will feel resistance from the anti-dislodgement component, thus providing the user with a sense of full penetration. With further insertion, the elastic membrane attached to the vulva begins to stretch inward along its curved surface, creating a certain amount of soft pressure on the vulva and vaginal opening. The massage protrusions simultaneously stimulate the clitoral tissue and the hemispherical granules, providing a massage and stimulation effect on the sensitive nerves in various parts of the vulva, giving the woman a feeling of fullness and strong stimulation to various sensitive areas, thus achieving a pleasurable and satisfying experience. The entire process of using this safety bag provides a novel experience for both men and women, greatly enhancing the quality of their experience. Attached Figure Description

[0012] The present invention will now be further described with reference to the accompanying drawings in the embodiments of the present invention.
[0013] Reference Figure 1-3The present invention includes an opening ring (1), a stretchable membrane (2) connected to the lower part of the opening ring (1), a guide connecting sleeve (8) connected to the lower part of the stretchable membrane (2), the guide connecting sleeve (8) connected to an anti-detachment component (9), and a liquid-holding bag (10) connected to the lower part of the anti-detachment component (9). The opening ring (1) is a silicone ring containing an elastic stainless steel ring to prevent the safety bag from sliding into the body when stretched, ensuring the normal use of the safety bag. The opening ring (1) is a silicone ring containing an elastic stainless steel ring, with an opening membrane (12) in the middle, and a micro-slit (15) in the middle of the opening membrane (12). Figure 5 As shown, a U-shaped annular groove (7) is provided between the stretching membrane (2) and the guide connecting sleeve (8), and expansion and contraction membrane strips (6) are evenly spaced on the U-shaped annular groove (7). Massage protrusions (3) are provided on the stretching membrane (2).
[0014] The open membrane (12) and the U-shaped annular groove (7) are used to provide gripping force to the penis, giving the man a feeling of tightness. The sides of the oral ring (1) are curved. The anti-slip component (9) is provided with a one-way swinging ear (14), such as Figure 4 As shown, the unidirectional swing side ear (14) is a component wrapped with a plastic strip, and the plastic strip component has a notch (16). The plastic strip component has a notch (16). The lower part of the mouth ring (1) is connected to the unidirectional swing side ear (14) by a pull strap (5). The stretch membrane (2) is provided with hemispherical silicone particles (4).
[0015] The guide connecting sleeve is glued to the anti-slip component at one end, and extends to the right opening of the U-shaped annular groove at the other end, where it is glued to the stretching membrane and the expansion membrane. The guide connecting sleeve and the stretching membrane are designed to have poor tensile properties; regardless of the tension or deformation of the stretching membrane during insertion, the anti-slip component to the upper edge of the U-shaped annular groove will not undergo significant deformation. The anti-slip component prevents the safety bag from slipping out with the penis during intercourse, ensuring normal use of the safety bag. Its external structure is a partially spherical cross-section in the middle, with a diameter equal to the outer diameter of the guide connecting sleeve. It has a hole in the middle with a diameter equal to the inner diameter of the liquid-holding bag. The spherical cross-section has two symmetrical one-way swing ears, which can only swing towards the opening ring and not in the opposite direction. The internal structure of the ear is a "skeleton" with two one-way swings. The external material is silicone with a hardness of no more than 1, which serves to provide overall connection and reduce or eliminate the feeling of foreign objects. Before use, the safety bag can be inserted into the vagina by the male by placing it on the penis, or by either the male or female using a retractable special auxiliary tool to insert it into the appropriate position. After sexual activity, there are two easy ways to remove the condom: one is to gently pull any strap to slowly pull it out; the other is to use a tool, inserting it about ten centimeters deep, and then removing it along with the condom. Due to differences in body shape between men and women, users should choose condoms of different lengths and thicknesses to achieve more satisfactory results.
