Detailed ways

The specific embodiments of the present utility model will be further described in detail below with reference to the accompanying drawings.

As shown in Figures 1 to 4, it includes a three-lumen tube 1 in the up-down direction. The three inner cavities of the three-lumen tube 1 are respectively an inflation chamber 2, a drainage chamber 3, and a medicine feeding chamber 4. The outer edge of the three-lumen tube 1 is The airbag 5 is provided on the side, and the airbag 5 is communicated with the upper end of the inflation cavity 2 through the inflation hole 6. The upper side of the drainage cavity 3 is provided with a first one-way valve 7 with an opening downward, and the upper side of the medicine feeding cavity 4 is provided with a second opening upward. For the check valve 8 , the opening pressure of the first check valve 7 is greater than the opening pressure of the second check valve 8 .

In order to prevent the gas in the airbag 5 from flowing out, the lower end of the inflatable cavity 2 is connected with a sealing device through the inflation tube 9. The sealing device includes a fixed sleeve 10 with an upward opening and coaxial with the inflatable tube 9. The support ring 11 at the lower end of the inflatable tube 9, the lower end surface of the support ring 11 is connected with a shielding plate 13 through a spring 12, the outer diameter of the shielding plate 13 is smaller than the inner diameter of the fixed sleeve 10, and the lower end surface of the shielding plate 13 can be in contact with the lower side wall of the fixed sleeve 10 The lower side wall of the fixed sleeve 10 is provided with an exhaust hole 14 that penetrates vertically. The inner diameter of the exhaust hole 14 is smaller than the outer diameter of the shielding plate 13 .

In order to facilitate the connection between the drainage cavity 3 and the negative pressure drainage bag, the lower end of the drainage cavity 3 is provided with a connecting head 16 through the drainage tube 15, and the connecting head 16 can be connected with the negative pressure drainage bag.

In order to facilitate the injection of medicinal liquid into the uterine cavity and prevent the medicine feeding cavity 4 from being polluted, the lower end of the medicine feeding cavity 4 is connected with a detachable sealing cover 18 through the medicine feeding tube 17 .

In order to prevent the device from hitting the inner wall of the uterine cavity, the upper end of the three-lumen tube 1 is hemispherical, and the upper end of the balloon 5 is flush with the upper end of the three-lumen tube 1 after inflation.

In order to fit the uterine cavity, the air bag 5 is inflated and inflated into a pear-shaped shape.

When the utility model is in use, after the patient completes the separation of intrauterine adhesions, the device is taken out, and the upper end of the device is extended into the patient's uterine cavity. Insert the nipple of the syringe into the exhaust hole 14, push the shielding plate 13 upward, the shielding plate 13 moves upward and squeezes the spring 12, the syringe is communicated with the inflation tube 9, and the gas in the syringe is injected into the inflation tube 9, and the gas passes through in turn. The inflation tube 9, the inflation cavity 2, and the inflation hole 6 enter the airbag 5, and the airbag 5 expands and adheres to the inner wall of the uterine cavity. 14, the shielding plate 13 moves downward under the pressure of the spring 12 and the gas in the air bag 5, and completely blocks the exhaust hole 14, the air in the air bag 5 cannot be discharged, and the air bag 5 maintains the inflated state to support the uterine cavity. It can prevent the uterine cavity from re-adhesion;

After the inflation is stopped, the connecting head 16 can be connected to the negative pressure drainage belt, the negative pressure device can be activated, the first one-way valve 7 is opened, and the liquid in the patient's uterine cavity is discharged outward and flows to the negative pressure drainage bag. A sealing cover 18 is installed at the lower end of the pipe 17, which is in a sealed state, and the second one-way valve 8 cannot be opened;

After the liquid in the patient's uterine cavity basically flows out, the negative pressure device is closed, the first one-way valve 7 is closed, the sealing cover 18 is removed, and the drug is injected into the patient's uterine cavity through the drug inlet tube 17, and the second one-way valve 8 is opened, The medicinal liquid enters the patient's uterus through the medicine feeding cavity 4. Since the opening pressure of the first one-way valve 7 is greater than the opening pressure of the second one-way valve 8, the first one-way valve 7 is closed when the second one-way valve 8 is opened. state, the medicinal liquid in the patient's uterine cavity cannot flow out from the drainage tube 15 to improve the therapeutic effect of the medicine. After the medicine is injected, the sealing cover 18 is installed on the lower end of the medicine feeding tube 17, and the second one-way valve 8 is closed;

When the patient needs to remove the device, the sealing device is removed, and the gas in the airbag 5 is discharged to the outside. If a small amount of gas remaining in the airbag 5 cannot be discharged, the inflation tube 9 can be connected with the negative pressure device, and the negative pressure device can be activated to remove the airbag 5. The gas inside is completely sucked out, so that the balloon 5 is in close contact with the outer edge of the three-lumen tube 1, and the device is pulled out from the patient's uterine cavity.

Compared with the prior art, the beneficial effect of the utility model is that: the three-lumen tube is respectively an inflation cavity, a drainage cavity and a medicine feeding cavity, which is convenient for drainage, and at the same time, medicine can be injected into the patient's uterine cavity before the patient removes the drainage tube, and the balloon After being inflated, it is a pear-shaped shape with a big upper and a small lower, which better fits the shape of the patient's uterine cavity, supports the uterine cavity, prevents the uterine cavity from re-adhesion, and prevents the drugs injected into the patient's uterine cavity from flowing out. , improve the therapeutic effect of the medicine, the structure is simple, the operation is convenient, the conception is novel, and the practicability is strong.
