Pressure-adjustable pessary

Abstract

The invention discloses a pressure-adjustable pessary. The pressure-adjustable pessary comprises an inflatable air bag, wherein the air bag is made of medical rubber or medical silica gel, an air cock is arranged on the air bag, the air cock comprises a hard cavity and a one-way valve body, the one-way valve body is located in the inner space, one end of the one-way valve body is provided with an air inlet hole, a connecting part is arranged on the air inlet hole, and the connecting part can be detachably connected with an air delivery pipe. The pressure-adjustable pessary has the beneficial effects that when inflation is needed, the air delivery pipe and an inflation pump are connected with the connecting part, air is inflated for the air bag by virtue of the air cock through the inflation pump, pressure in the air bag increases continuously, a sealing part and a first limiting convex edge tightly attach to each other continuously, and finally, the airtight sealing purpose is realized. Meanwhile, the air delivery pipe can be detached. When the pessary needs to be taken out, the whole one-way valve body can be pressed towards the inside direction of the air bag by hands, and then air flow in the air bag flows towards gaps among the hard cavity by the one-way valve body, so that the size of the air bag becomes small.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a pressure-adjustable pessary. Background technique [0002] At present, pessary is generally used for the treatment of patients with pelvic floor dysfunction, and surgical treatment is performed for particularly severe cases. Pessary is an economical, simple, safe and effective method for the treatment of uterine prolapse. That is, it can participate in general labor, so it is very popular among patients. [0003] However, the currently used pessaries cannot be individualized, and the medical personnel check the size of the top of the vagina to select different sizes of pessaries, which causes some patients to suffer from local discomfort due to compression or the pessaries are easy to fall off and have no therapeutic effect.

Problems solved by technology

[0003] However, the currently used pessary cannot be individualized, and the medical staff checks the size of the top of the vagina to choose a pessary of different size, which leads to some patients with local discomfort due to compression or the pessary is easy to fall off and has no therapeutic effect.

[0004] The Chinese invention patent with the publication number CN204890306U discloses an inflatable pessary, but this solution still has shortcomings. The plastic tube and the inflation valve are not detachable, and the plastic tube is directly placed in the vagina, which is easy to dislodge bacteria outside the body. If it is brought into the vagina to cause infection, the inflatable valve needs to be pasted and fixed on the body surface, which will increase the discomfort of the patient
