Further, the pockets with filler material are added along the shaft of the condom to enhance the shape and size of the user's penis.

[0008] Scott Praml in U.S. Pat. No. 6,895,967 B2 issued on May 24, 2005, entire contents of which are incorporated herein by reference, discloses a condom with an inner wall and outer wall defining an annular chamber. The chamber is connected with an internal airway and a removable handheld pump as the air source. The air travels along the internal airway into the air chamber, and allowing it to be inflated at desirable time. Air vents disposed at the base of the chamber allow for quick deflation. The handheld pump and associated flexible tube can be disconnected from the condom for reuse.

[0009] None of the devise is capable of expanding both circumferentially and longitudinally by a reservoir automatically squeezed between the users' body pressure to provide the option for controlling its expansion and to reach the desired size. This invention allows users to reach maximum comfort and pleasure during the sexual relations.

[0010] The present invention related to a condom with a fluid filled reservoir attached to the open end. A prophylactic or prosthetic device with the conventional function to prevent unwanted pregnancy and protect against communicable diseases, as well as provide controllable enlargement portions to increase sexual pleasure for both male and female users. The condom comprises a various number of inflatable tubular portions along the shaft of its length, and an inflatable dome shape chamber at the anterior portion. A reservoir filled with fluid is attached to the top portion of the condom base to supply the fluid to the inflatable portions. The fluid inside the reservoir will be automatically squeezed into the condom during the intercourse when body pressure at the pubic areas between the partners pushed against each partner.

[0011] The condom further includes one handheld feeding pump with a tube connected to the reservoir. The pump is functioning as the source of additional fluid for the reservoir. The fluid filled feeding pump could be manually activated by the user and injects additional fluid into the reservoir to further enlarge the condom. One receiving empty container with a relief valve is provided to release the fluid from the inflated portions per user's discretion to reduce the size of the condom anytime during the intercourse. The reservoir attachment along with its associated devices may apply to both male and female condoms according to its design.

[0012] In alternative embodiments, the condom includes a circular donut shape reservoir or an U shape reservoir that attached to the base or the open end of the condom along with several compartments inside for feeding a pre-determine amount of fluid to the inflatable portions. The reservoir is to be squeezed between the base of the penis and the vulva during the intercourse. The reservoir gradually injects the fluid into the inflatable portion of the condom through the connecting microtubules. Further, a sodium acetate heat pad is added inside the reservoir to heat the fluid when triggered, and to enhance the sexual enjoyment.

[0025] The preferred embodiments of the present invention described below relate to a male condom illustrated in FIG. 1 is formed of latex or polyurethane. The condom has an open end 10 with a ring, a closed anterior chamber 17 and a tubular wall 9 interconnecting both ends and is attached with inflatable tubular portions 16 along the shaft of the condom. The inflatable portions are used to increase the circumferential and the longitudinal size of the condom when fluid is injected into them. A reservoir 1 is attached to the top of the open end or the base of the condom above the condom ring 10, and there are several compartments 3 inside the reservoir 1 for pre-determined amount of fluid to be stored. Microtubules 15 connect the compartments to the designated inflatable portions of the condom. Furthermore, a sodium acetate heat pad 2 is attached inside the reservoir to heat the fluid when triggered.

[0026] An inflatable dome shape chamber 17 at the front end of the condom receives fluid from reservoir 1, once inflated, a substantially dome-shaped portion to be formed at the closed end, there are inflatable semispherical bumps 18 cover the dome to increase the sensation for female partner.

[0027] In alternative embodiments shown on FIG. 2, the condom includes a circular donut shape reservoir 20 & FIG. 3 or an upside down U shape reservoir 20 & FIG. 10 that attached to the base or the open end of the condom along with several compartments 22 inside for feeding a pre-determined amount of fluid to the inflatable portions, a circular sodium acetate heat pad 21 is included inside the reservoir. The reservoir is to be squeezed between the base of the penis and the vulva during the intercourse. While under body pressure, it gradually injects the heated fluid into the inflatable portions of the condom through the connecting microtubules 15.

[0028] A fluid filled handheld pump 5 with a control valve 6 are provided for adding fluid into the reservoir if needed. The handheld pump is connected with a tube 7 to the reservoir, and branches into microtubules 8 to distribute the fluid into the compartments in the reservoir. The diameters of the microtubules determine the amount of the fluid to be channeled into certain compartment.

[0029] A relief microtubules 19 and control valve 12 is provided to drain the excess liquid to the empty container 11 through relief tube 13 if needed in order to control the size of the inflatable portions.

[0030] The condom is packaged at a folding position FIG. 10, there are two ears 25 made of the same elastic material as the condom and attached to the interior wall at the middle section of the condom shaft. The ears to be held by both hands to help slip the condom onto the penis, after place half of the front end on the penis, and then the rest folded portion could be rolled over to complete the condom installation.

[0031] The condom should place over the penis and insert into the vagina of the female, prior to apply any of it functions. A control valve 6 is provided to stop the handheld pump from prematurely feed the liquid into the reservoir, and a clamp 4 is provided at the base of the reservoir to stop the fluid flow prior to the application of the condom. Once the condom is donned the penis, and after inserted into the vagina, the clamp 4 could be removed; the handheld pump control valve 6 could be click to open if needed.

[0032] The reservoir on FIG. 1 is designed to situate between the two partner's pubic area, it will automatically feed the fluid into the inflatable portions in the condom during the intercourse when it is squeezed between the partners at the pubic areas. The sodium acetate heat pad 2 could be triggered to lease the heat for the fluid inside the reservoir prior to the intercourse. A handheld pump 5 is connected with microtubules 8 to the reservoir; a single tube 7 is branched into a few microtubules 8 and feed the fluid into designated compartment 3 in the reservoir. The compartments 3 in the reservoir 1 store pre-determinated amount of fluid to each designated inflatable portion on the condom. The fluid filled handheld pump is able to continuously supply the reservoir with additional fluid and to be activated by the user if needed. The control valve 6 is also functioned to prevent backflow.

[0033] The handheld pump 5 is used to control the additional fluid for the reservoir, and the empty container 11 and the relief valve 12 is for reducing the size of the inflatable portions if needed during the coitus. By activating the relief valve 12, the fluid will drain away into the empty container through the relief tubules 19 & 23, which are connected from each inflatable portion to the container. There are also one way valves 14 inside each microtubule or at the inlet of the inflatable portions to prevent back flow to the reservoir while under pressure.

[0034] A close end dome shape (Section C-C) is specially designed to form a shallow pocket 24 at the bottom of the front end, so the space will not be squeezed out after the inflation, and is used for the storage of semen.

[0035] The condoms embodying the invention provide more fun and pleasure to use than those currently available. It will be understood that each of the elements described above, or two or more together, may also find a useful application in other types of constructions differing from the types described above.

[0036] While the invention has been illustrated and described as a reservoir attached, heat pad attached, inflatable and controllable condom for increasing the pleasure for the users, however, it is not limited to the details shown, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
