Description

Technical Field

[0001] The present application relates to the field of medical devices, and in particular to an umbrella-shaped inflatable pessary. Background Art

[0002] Pelvic organ prolapse is the abnormal position and dysfunction of organs caused by the descent of pelvic organs due to abnormal pelvic floor muscles and fascia tissues. With the progress of an aging society and the high attention paid by people in modern society to physical health and quality of life, the incidence of pelvic organ prolapse continues to rise. Pessaries are a non-invasive mechanical device inserted into the vagina that provides physical support for the vaginal wall and prolapsed organs, maintains the normal anatomical position of prolapsed organs and tissues, and achieves the purpose of treatment. Due to the advantages of pessaries such as non-invasiveness, low cost, wide range of use, and few complications, they are internationally recognized as the first-line non-surgical treatment for pelvic organ prolapse.

[0003] The pessaries currently used include support pessaries and filling pessaries. Support pessaries are mainly ring-shaped, and filling pessaries include horn-shaped pessaries, donut-shaped pessaries and cube-shaped pessaries. However, the above-mentioned pessaries are mostly manufactured in an integrated molding method, with fixed size and volume. Patients often need to try on different types of pessaries, resulting in a waste of resources. Moreover, when inserting and removing the pessary, the patient needs to fold the pessary in half by hand so that the folded width adapts to the width of the vaginal opening so that it can be smoothly inserted or removed from the vagina. However, in order to ensure its mechanical support, the above-mentioned pessary has a hard texture, which makes it difficult for patients to fold it in half, increasing the difficulty of operation, and most patients give up using pessaries due to the inconvenience and pain of the insertion and removal process. In addition, due to the different degrees of prolapse and different vaginal anatomical conditions of different patients, there are also many patients who cannot find a suitable type of pessary.

[0004] Chinese invention patent CN219306884U discloses an adjustable, self-removable, inflatable pessary, which includes a lifting part and an inflatable part. The lifting part is an inverted umbrella, which is inserted into and out of the body, expanded and contracted through a support component, an expansion bracket, and an adjustment component, and inflated through the inflatable part. The retractable and retractable components of the pessary are relatively complex, and it needs to be kept in the body during use, which is not very comfortable to use. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide an umbrella-shaped inflatable pessary, which is easy to take and put and has high comfort in use.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: an umbrella-shaped inflatable pessary, including a pessary body and a delivery catheter, the delivery catheter is roughly placed outside the pessary body, the pessary body includes an umbrella-shaped head and an inflation cylinder, a connecting hose is arranged between the umbrella-shaped head and the inflation cylinder, a one-way air valve is arranged in the connecting hose, and the umbrella-shaped head is an inflatable air bag.

[0007] Furthermore, the umbrella-shaped head is made of latex. The umbrella-shaped head has an upper bottom surface and a lower bottom surface, and a connecting channel is provided between the upper bottom surface and the lower bottom surface, and the connecting channel is isolated from the inner side of the umbrella-shaped head. When the umbrella-shaped head is inflated to the maximum extent, the overall height is 35mm-45mm, and the diameter of the lower bottom surface is 51mm-76mm. The delivery catheter comprises an outer catheter and an inner catheter that are relatively movable. The length of the outer catheter is 28 mm-32mm, the diameter of the outer catheter is 20mm, the length of the inner catheter is 32-38mm, and the length of the inner catheter is slightly longer than that of the outer catheter. The one-way air valve is made of latex, and the one-way air valve comprises an air valve lumen, a valve plate, a movable valve leaf and a cover. The inflation cylinder is detachably connected to the connecting hose.

[0008] The beneficial effects that the present invention can achieve are: The present application places an uninflated pessary in a delivery catheter. As the delivery catheter enters the vagina, the inner catheter is pushed, and the uninflated pessary in the outer catheter is inserted into the patient's vagina, making it more convenient and quick to place and use. The one-way air valve is connected to the inflator to inflate the air, and the umbrella-shaped head with a small top and a large bottom gradually expands and increases in the patient's body, and has a high degree of adaptability to the human body. While the side wall of the inflated umbrella-shaped head provides support through gas pressure, its soft latex material also ensures the comfort of the patient during use. The size of the umbrella-shaped head can be controlled by the gas filled in, which serves the purpose of adapting to different degrees of prolapse and different vaginal volumes, and reduces the waste of the pessary caused by repeated trial wearing. The pessary of the present invention is placed in the vagina through a delivery catheter, and the catheter has a small diameter, which is easy to put into the vagina. The one-way air valve ensures that there is no air leakage after inflation. When taking it out, the air valve is pinched by hand, and the gas leaks out after the air valve is deformed, and the pessary shrinks, which is easy to take out. BRIEF DESCRIPTION OF THE DRAWINGS
