BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to a device for transvaginal haemostasis, in particular to a pessary for transvaginal haemostasis with a hemostatic function in which the radial dimension of the balloon body of the pessary can be changed.

2. Description of the Related Art

Pelvic organs include a uterus, a vagina, a bladder and an intestine. Uterine prolapse is the prolapse of one of the pelvic organs, and is particularly referred to the situation that the uterus prolapses into the vagina and even out of the body. Uterine prolapse is caused by increased abdominal pressure and reduced support of the pelvis cavity, which mainly happens to women who suffer from a long-term cough, are pregnant or obese, or are on their feet for a long time or under a vaginal surgery. During the pregnancy, since the abdomen becomes larger, the abdominal pressure increases, and it is required to squeeze the fetus out of the vaginal opening of the pelvis cavity during parturition, the support of the pelvis cavity tends to reduce. On the other hand, the vaginal surgery causes damage to the muscles and nerves of the vagina, which also leads to reduction in the support of the pelvic cavity. Thus, uterine prolapse is commonly seen in women who are pregnant or under a viginal surgery, or have multiple births.

The most common approaches to treat the uterine prolapse is to cut the entire uterus or to push the uterus back to the original position by a vaginal surgery. The risk of a hysterectomy is low and the recovery is quick, but it puts a lot of pressure on the patient. If the uterus is pushed back to the original position by the vaginal surgery, the pressure of the patient is small, but the recurrence rate of the uterine prolapse is high. Therefore, in order to prevent a uterine prolapse after birth or a recurrence of the uterine prolapse after surgery, the uterine prolapse after birth or vaginal surgery can be prevented by inserting a pessary into the vagina to support the uterus along with performing a pelvic floor exercise to train the muscles of the pelvic organs and to therefore increase the support force of the pelvic cavity.

The existing pessaries can support the uterus and prevent uterine prolapse only after parturition or vaginal surgery, but cannot achieve hemostasis after parturition or vaginal surgery. In general, hemostasis is achieved by inserting the existing pessary into the vagina and filling the vagina with a filler to stop bleeding, which leads to a complex procedure and cannot stop bleeding in time. Because the existing pessaries are in a variety of dimensions, the doctor needs to spend a lot of time on the selection of the dimension. This will, particularly in the case where hemostasis is urgently required, impede the health of the woman or leads to a threat to the life of the woman after parturition or under vaginal surgery, while the patient also needs to spend a lot of money purchasing the pessaries with different dimensions for testing purposes.

Accordingly, it is necessary to improve the existing pessaries to reduce the time on selecting a pessary with a proper dimension as well as the cost in using the pessaries of various dimensions, while reducing the complexity in stopping the bleeding after the surgery and achieving a timely stop of the bleeding.

SUMMARY OF THE INVENTION

In order to solve the problems above, the invention aims to provide a pessary for transvaginal haemostasis, the dimension of the pessary can be changed according to needs, and the pessary has a hemostatic function.

The invention provides a pessary for transvaginal haemo stasis, including a balloon body and a support body. The balloon body is made of an expandable material. The balloon body is provided with a cavity having a filling hole to permit fluid to be filled into or drawn out of the cavity through the filling hole. The balloon body is provided with a first end and a second end. The balloon body is provided with at least one hollow passage running through the first end and the second end of the balloon body and not intercommunicating with the cavity. An outer surface of the balloon body is provided with at least one channel also running through the first end and the second end of the balloon body. The support body is with an engaging end and a support end. The engaging end is engaged with the second end of the balloon body. The support body is provided with a through-hole intercommunicating with the passage. An outer surface of the support body is provided with at least one concave portion corresponding to the channel.

The outer surface of the balloon body is provided with at least one ring protrusion, therefore the balloon body can form a better positioning effect with an inner wall of the vagina.

A cross section of the ring protrusion is in a circular shape or a semi-circular shape, therefore reducing the damage to the vagina portion without uncomfortable feeling upon the insertion and withdrawal.

A radial dimension of the balloon body after a radial expansion is larger than the radial dimension of the support body, therefore the balloon body can exert a larger pressure effect on the vaginal wall.

The outer surface of the support body is in flush connection with the outer surface of the balloon body, therefore reducing the damage to the vagina portion without uncomfortable feeling upon the pessary is inserted into the vagina portion.

The outer surface of the support body is provided with an angle-guiding portion at the support end, therefore the pessary is inserted into the vagina portion with a smooth effect.

The through-hole of the support body is provided with an angle-guiding portion at the support end, therefore the pessary is inserted into the vagina portion with a smooth effect.

A surface of the concave portion is in flush connection with the channel of the balloon body, therefore reducing the damage to the vagina portion without uncomfortable feeling upon the pessary is inserted into the vagina portion.

The through-hole is in flush connection with a tube wall of the passage, therefore a uterine secretion can be smoothly guided out of the through-hole and the passage.

The filling hole is formed at the first end of the balloon body, therefore the fluid can be conveniently filled into the balloon body.

Accordingly, the pessary for transvaginal haemostasis of the invention can be positioned at a predetermined position in the vagina through the balloon body. In addition, since the balloon body and the support body jointly support the uterus, the support for the uterus is assisted to prevent the pessary from coming off. In addition, when the pessary for transvaginal haemostasis is used after surgery, not only the uterine prolapse can be prevented, but also pressure can be exerted on the vaginal wall by the balloon body to achieve hemostasis under high pressure. Furthermore, the pessary for transvaginal haemostasis of the invention permits the balloon body to be filled with a proper amount of the fluid according to different requirements of the user. This can achieve the advantages of quick adjustment in the dimension of the balloon body, the reduction of time on selecting a pessary with a proper dimension, as well as the reduction of the cost for purchasing the pessaries of various dimensions.
