Description

pressure adjustable pessary

technical field

The invention relates to the technical field of medical devices, in particular to a pressure-adjustable pessary.

Background technique

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.

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.

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. If it is brought into the vagina to cause infection, the inflatable valve needs to be pasted and fixed on the body surface, which increases the discomfort of the patient. However, if the plastic tube is pulled out by force, the air pressure of the blind end cuff cannot be released when taking it out, so that it is convenient to take it out.

After the air pressure in the air bag increases, the sealing portion and the first limiting convex edge can be continuously connected. snug fit.

Its beneficial effect is that since the connection part can be detachably connected with the air delivery tube, when inflation is required, the air delivery tube and the air pump can be connected with the connection part, and then the air bag can be inflated through the air nozzle through the air pump, and the During the process, the air flow is filled into the airbag through the air outlet hole with the one-way valve disc, the pressure in the airbag will continue to increase, and the pressure of the air pressure will act on the entire one-way valve body in reverse, making the one-way valve The body moves closer to the first limiting convex edge of the hard chamber, so that the sealing part and the first limiting convex edge can be continuously and closely attached to finally realize airtightness. After inflating to the patient's comfort level, the airbag can be well fixed in the patient's vagina to stop inflating. At the same time, the air delivery tube can be disassembled, and only the airbag is retained in the patient's vagina.

When it is necessary to take out the pessary, you can directly press the entire one-way valve body toward the inside of the airbag by hand, so that the sealing part is slightly separated from the first limiting convex edge, and the airflow in the airbag can pass through the one-way valve The body flows out to the gap between the hard chambers, so that the volume of the air bag becomes smaller, so that it is easy to take out.

In some embodiments, a first sealing ring is provided on the first limiting protrusion, and a second sealing ring is provided on the sealing part. The beneficial effect is that after the two sealing rings are provided, the sealing rings can be made of rubber material, so as to achieve a good sealing effect.

In some embodiments, the first sealing ring and the second sealing ring have different diameters. The beneficial effect is that two sealing effects can be realized at the same time because the diameters of the two are different, so that the sealing effect is better.

In some embodiments, the connection part is in the form of clamping or threaded connection. Its beneficial effect is that it can be connected and disassembled more conveniently in the form of clamping or threaded connection. Operation is easier.

In some embodiments, the hard chamber sinks into the airbag, and the first limiting protrusion is flush with the surface of the airbag. The beneficial effect is to ensure that the hard cavity does not protrude from the air bag, causing discomfort to the patient.

In some embodiments, the outer side of the hard chamber is provided with an integrated positioning lip, and the positioning lip is attached to the surface of the airbag. The beneficial effect is that the hard chamber can be fixed on the surface of the airbag after the integral positioning convex edge is provided.

In some implementations, the contact surface between the sealing portion and the first limiting lip is set on an inclined plane. The beneficial effect is that, as the air pressure in the airbag increases, the contact pressure between the sealing part and the first limiting lip will become larger and better to achieve a better airtight effect.

In some embodiments, the balloon is an annular balloon. The beneficial effect is that there can be a hole for liquid to flow through in the middle of the air bag, so that some dirt in the vagina can be easily discharged.

In some embodiments, the airbag is provided with a liquid flow hole, and the liquid flow hole is located at the side of the hard chamber. The beneficial effect is that it facilitates the discharge of some vaginal dirt.

In some embodiments, an air leakage hole is provided on the second limiting protrusion. The beneficial effect is that, when taking it out, even if the one-way valve body is pressed down too much, even if the one-way valve body is closely attached to the second limiting convex edge, the gas in the airbag can leak out through the air leakage hole, Finally, it flows out to the gap between the hard chambers through the one-way valve body.
