Detailed Description

The invention will now be described in detail with reference to fig. 1, wherein exemplary embodiments and descriptions of the invention are provided to explain the invention, but not to limit the invention.

As shown in fig. 1, the invention provides an adjustable vaginal mold, which comprises a flexible hollow mold sleeve 1 formed according to the shape of a vagina, wherein one end of the mold sleeve is provided with an opening 11, the other end of the mold sleeve is closed so as to adapt to the physiological requirements of men, an interlayer 12 is arranged in the sleeve wall of the mold sleeve, and the interlayer expands radially after being inflated, so that the diameter of the mold can be adjusted; the interlayer is internally provided with a sacculus 2, and the sacculus is expanded to axially extend the interlayer, so that the length of the die is adjustable. Therefore, the vaginal mold disclosed by the invention can adapt to the requirements of different individuals, and is not required to be provided with molds of different models, so that the cost can be saved, and the vaginal mold is convenient to use and strong in adaptability.

Preferably, the die sleeve 1 comprises a flexible hollow cylindrical inner layer 13, the outer end of the inner layer is provided with the opening, and the inner end of the inner layer is closed and is in a semi-spherical shape, so that the die sleeve can adapt to the physiological requirements of men; the outside of the inner layer is coated with a flexible second layer 14, and a closed interlayer is formed between the second layer and the inner layer. The interlayer is inflated to expand radially, so that the diameter of the hollow inner cavity of the inner layer can be changed, and the diameter of the inner cavity of the inner layer can be kept at a proper size through the inflation amount, so as to meet the physiological requirements of individuals.

Specifically, the inner end of the second layer is converged to the semi-spherical inner end of the inner layer, so that the inner end of the whole mold is ensured to be semi-spherical, the outer end of the second layer is connected with the outer end of the inner layer, and the outer end of the inner layer is ensured to have a larger opening; a ring pad 3 is radially arranged at the joint of the two, and the diameter of the inner cavity of the ring pad is larger than that of the opening, so that the formation of obstacles is avoided; the air valve 4 is embedded in the ring pad, and the air valve can adopt the existing air valve such as ball air valves and the like, so that the air valve is not exposed to the outside, and the damage is avoided; meanwhile, an external air source can be filled into the interlayer through the air valve, and an air filling needle is generally inserted into the air valve and then an air filling ball is used for filling air; other modes can be adopted to ensure that the gas is not leaked after the inflation.

Preferably, the saccule 2 is a plurality of air sacs axially arranged in the interlayer, and each air sac is axially abutted against the inner wall of the interlayer after being inflated and expanded, so that the interlayer is extended under the pressure action of the air sacs, and the length of the die is adjustable. And the air bags are simultaneously inflated through the first air valves 5 arranged on the ring pads, so that the stress on the inner wall of the interlayer is uniform, and the interlayer is easier to extend. In the implementation process, the plurality of air bags are arranged at intervals along the circumferential direction of the interlayer, for example, 6, 8, 12 air bags and the like are adopted, the outer ends of the air bags are communicated with an air ring 6 which radially surrounds the interlayer, the air ring is connected with a first air valve, an external air source enters the air ring through the first air valve, air in the air ring enters the plurality of air bags simultaneously, and the plurality of air bags are inflated simultaneously; the inner ends of the inflated air bags can simultaneously abut against the inner walls of the inner ends of the interlayer, the air bags axially expand along with continuous inflation, the inner ends of the flexible interlayer are abutted against and do not axially extend, and therefore length adjustment of the die is achieved.

Preferably, the second layer is externally wrapped with a flexible third layer 15, forming a closed outer space 16 between the third layer and the second layer, which outer space expands radially upon inflation. Therefore, under the condition that the interlayer is not inflated, the inner layer and the second layer can be attached together due to the flexibility, and the diameter of the hollow inner cavity of the inner layer is increased. In the implementation process, the inner end of the third layer is converged to the semi-spherical inner end of the inner layer, so that the inner end of the whole mould is ensured to be semi-spherical; the outer end of the third layer is connected to the ring pad, an external air source can be filled into the outer layer space through an additional air valve 7 embedded in the ring pad, and the additional air valve 7 and the interlayer air valve are consistent in design and function. The outer space inflation of the invention can be suitable for individuals with larger size, and in the implementation process, a fourth layer, a fifth layer and the like can be coated outside the third layer, thereby further improving the adaptability of the mould.

Correspondingly, a plurality of other air bags 8 are axially arranged in the outer space, and each other air bag is axially abutted against the inner wall of the outer space after being inflated. The principle, the function and the function of the other air bag and the outer layer space are consistent with those of the air bag and the interlayer. And the other air bags 8 are inflated simultaneously through the second air valve 9 arranged on the ring cushion, and the principle, the action, the function, the realization mode and the like of the air bags are the same as those of the first air valve. Thereby, the adjustment of the length of the large-diameter die is realized. In the implementation process, under the condition that the interlayer is not inflated, the plurality of air bags in the interlayer are attached to the interlayer, so that the increase of the diameter of the hollow inner cavity of the inner layer is not influenced. By adopting the mode, the invention realizes the independent control of the length and the diameter of the die and has stronger adaptability.

The ring pad is made of elastic material, so that the opening is ensured to have enough size. The inner layer, the second layer, the third layer, the ring pad, the air bag and the like are all made of medical rubber or medical silica gel, so that the whole mold can be guaranteed to have enough hardness, can be guaranteed to have better softness, and is suitable for stretching expansion. When in use, the interlayer or the outer space is inflated through the air valve or another air valve according to the size of an individual, whether the air bag is inflated or not is determined according to the individual so as to adjust the length of the mould to a proper position, and then the mould is placed in the vagina; after use, the disposable medical plastic can be taken out for cleaning, disinfecting and reusing, and can also be used once and then replaced with a new mold for treatment.
