The elastic hollow tube includes two internal chambers inside the hollow tube that are connected by at least one damping hole, such that the hollow tube is configured to offer resilient resistance to the user's vaginal compression when fluid in the tube is forced, by the user's vaginal compression, from a first one of the internal chambers, through the damping hole, into a second one of the internal chambers.

## Background
FIELD OF THE INVENTION
This invention relates to an exercising device for use by woman for the vaginal muscles or pelvic muscles, which are the group of muscles involved in women's sexual response.
BACKGROUND OF THE INVENTION
The current publicly known solution for vaginal relaxation caused by birth of children is surgery. It is painful for the patient and it can't strengthen the muscle around the vagina. Its cost is high. Now there is no exercising device for vaginal muscle.
In the prior art, various exercise devices have been developed in an attempt to address the vaginal flaccidity or relaxation caused by childbirth.
In U.S. Pat. No. 4,574,791, a vaginally-inserted member is connected by a flexible cable to an exterior support body which allows the vaginally-inserted member to reciprocate inside the vagina when the user contracts and relaxes the vaginal muscles.
Additional prior art includes U.S. Pat. No. 4,687,002, U.S. Pat. App. Pub. No. 2002/0142895, U.S. Pat. App. Pub. No. 2002/0142896, U.S. Pat. No. 4,050,449, U.S. Pat. No. 5,865,715, U.S. Pat. No. 5,531,226, German Pat. App. No. DE29910732U1, and Int. Pat. Appl. No. PCT/AU92/00228.
In the prior art, the resistance of the devices is fixed, and cannot be changed by the user.
SUMMARY OF THE INVENTION
The object of this invention is to provide an exercising device, by using which women can strengthen their vaginal muscle and solve the problem of vaginal relaxation and thus improve the sexual feeling.
One preferred embodiment of the device of the present invention comprises a lid, an elastic tube and fluid. The lid is joined to the inner side of the tube, forming a sealed chamber where said fluid is sealed within. The sealed chamber has a partition component whose peripheral surface is attached to the inner surface of the sealed chamber. The partition component divides the sealed chamber into two chambers. The partition component has at least one damping hole which connects the two chambers.
To improve the device, the sealed chamber has a brace which joins the partition component in its center hole, forming a rotatable structure. The partition component is attached with a resistance control element which is fixed on the brace. The resistance control element and the partition component have a closely touched interface.
When exercising, the user puts the device into the vagina and tries to squeeze the tube with vaginal muscles and then relaxes the muscles. Repeating the hold and relax exercise will strengthen the group of muscles and the problem of vaginal relaxation will be solved. The vaginal muscles will become stronger as the exercise goes on.
To improve the effect of the vaginal exercise, tubes of different diameters will be provided to the same client. It's especially useful for young mothers who just give gave birth to children. Users can choose to use different tubes according to their own condition at different exercise stage. By doing so, users can change the squeezing power and choose tubes of appropriate size according to the size of their vaginas. For those who have the problem of vaginal relaxation, tubes of larger diameter will be used at the beginning stage. As the group of vaginal muscles grows stronger, tubes of smaller size will be used.
To maintain a rigid shape and make it possible for users to put the device into their vagina, a brace made of hard material, such as engineering plastic, can be added to the tube. To make it easier to put the tube into vagina, lubricant such as water or vitamin E will be put on the tube's surface. The shape of the tube can be made like the man's penis. Improvement can be made to make the device also function as a massager.

DESCRIPTION OF THE PREFERRED EMBODIMENT
The first embodiment is illustrated in the drawing FIG. 1. The elastic tube I is cylindrical, the left end of which is formed as a hemisphere to simulate the glans. The brace 2 is a shaft, whose left end is formed as a shell and right end is conglutinated with the tube 1 to form a sealed chamber. Fluid is sealed in the chamber. The brace 2 can maintain a rigid shape of the device and make it possible for users to put the device into their vagina. When the group of vaginal muscles squeezes the tube 1, the resistance of the device comes from the elastic deformation of the tube 1 and the fluid sealed inside. The tube 1 can be made of elastic material such as rubber, silica gel or other suitable materials. The brace 2 can be made of hard material, such as engineering plastic, metals or other suitable materials. The change of the pressure which is given by the hand to the outer part of the tube 1 will effect the change of the device's resistance. Different resistance at different exercising stages will make for the strengthening of muscles.
The second embodiment is illustrated in the drawing FIG. 2, 3, 4. The elastic tube 1 is conglutinated with the lid 7. They form a sealed chamber with the brace 2, the retainer 6 and the seal 8. The fluid is sealed in the chamber. The partition component 4 is conglutinated with the tube 1 on its round side. The brace 2 is a shaft, whose left end is formed as a shell to protect the tube's left end. The resistance control element 5, the first retainer 3 and the second retainer 6 are fixed on the brace 2.
The resistance control element 5 and the partition component 4 have a closely touched same-shaped interface. The resistance control element 5 has at least one gap. The partition component 4 is longitudinally fixed on the brace 2 by the first retainer 3 and the resistance control element 5. The lid 7 and the seal 8 are longitudinally fixed on the brace 2 by the second retainer 6. The seal 8 can prevent the inner fluid from leaking out while the brace 2 rotates in the lid 7. The damping element 10 has a cone-shaped side as shown in the FIG. 3. It fits in the cone-shaped hole in the partition component 4. There is a damping hole on the damping element 10. The damping element 10 is limited in the hole of the partition component 4 by the third retainer 9 which is a crossed element. When the vaginal muscle squeezes the left chamber of the tube 1, the damping element 10 will be pressed into the cone-shaped hole of the partition component 4 by the fluid in the left chamber. The fluid in the left chamber will be squeezed into the right chamber of the tube 1 through the damping hole on the damping element 10. So, in this embodiment, the resistance comes mainly from the damping of the fluid by the damping hole. Because the interface of the damping element 10 and the partition component 4 is cone-shaped, when the fluid in the right chamber flows into the left chamber under the pressure of the hand on the right chamber of the tube 1, the damping element 10 will move left to the position of the retainer 9. In this condition, the sectional area of the fluid that passes through the partition component 4 is much larger than when the fluid flows from the left chamber to the right chamber. So the fluid can be quickly pressed back to the left chamber. This structure works like a check valve. As seen in FIG. 4, there can one or more such kind of damping hole on the damping element 10. While the brace 2 rotates relatively to the tube 1, the resistance control element 5 will rotate relatively to the partition component 4. When the resistance control element 5 rotates through different angles, different number of damping holes will be covered by the resistance control element 5. So when the fluid goes from the left chamber to the right chamber, the resistances of the device at different positions are different. So, by rotating the brace 2, the resistance of the device can be changed. The device can offer different resistance for the user. As the vaginal muscle grows stronger, the user can choose stronger resistance for their exercise. Stronger resistance will help the muscle grow stronger. The fluid in the right chamber can go back to the left chamber while the user's hand squeezes the right chamber.
The third embodiment is illustrated in the drawing FIGS. 5 and 6. The tube 1 is conglutinated with the brace 2 at the right end. The elastic parts 11 and 12 are joined by four semi-ellipses, formed like a football. They can be made of rubber. The brace 2 goes through the center of the elastic parts 11 and 12. In this case, the resistance of the device comes from the elastic deformation of the elastic parts.
