Hysteroscopic technology has been widely used in gynecological clinics. Although the uterine cavity communicates with the outside through the cervix and vagina, because the front and rear walls of the uterine cavity are closely attached, it needs to be inflated before peeping under the hysteroscope. The current main method is to inject liquid directly into the uterine cavity, and expand the uterine cavity under a certain fluid pressure. Specifically, take 5% glucose solution medium as an example to illustrate: firstly, dilate the cervix to the required size, place the hysteroscope into the internal os of the cervix along the direction of the uterine cavity, and at the same time inject 5% Glucose solution is injected into the uterine cavity, rinsed, and then infused with glucose solution into the uterine cavity to expand the uterus, usually 50-100 ml. After the uterine cavity is fully dilated, the hysteroscope can be used to observe the shape and endometrium of the official cavity, rotate the hysteroscope to check the various parts of the uterine cavity in sequence, and finally check the cervical canal, and then slowly withdraw from the cervix. During the examination, part of the swelling fluid may leak from the cervix, and the infusion of glucose solution must be maintained, and air embolism accidents caused by air inflow caused by the glucose droplet must be avoided. The above inspection process is inconvenient to operate, the patient suffers a lot, the angle of observation effect is not clear, and there is a risk of water intoxication or embolism.

Further, at least one inlet tube 4 is provided on the tube wall 13 of the main silicone tube 1, and the inlet tube 4 extends along the length direction of the main silicone tube 1 and at least partially extends into the balloon 3, so that The part of the air intake pipe 4 located inside the balloon 3 is provided with at least one vent hole 41 so that the air intake pipe 4 is in fluid communication with the balloon 3, and the part of the air intake pipe 4 located outside the balloon 3 is provided with an interface valve 42 , the inlet pipe 4 communicates with the inflation and deflation mechanism 2 through the interface valve 42 .

For the uterine cavity distension device provided above, when checking gynecological uterine cavity lesions, without inflating the balloon 3, the medical staff sends the balloon 3 into the uterine cavity with the help of the main silicone tube 1, and then operates the inflation and deflation mechanism 2 Inflate the balloon 3 through the air inlet tube 4, and the balloon 3 expands to expand the uterine cavity. At this time, insert the hysteroscope from the opening end 12 of the main silicone tube 1 until it reaches the sealing end 11 of the main silicone tube 1. Observation of uterine lesions through hysteroscopy provides a basis for diagnosis. The device is simple and convenient to operate, avoids cumbersome procedures during examination, and reduces uterine cavity and cervical trauma injuries to patients during examination. After the inspection is completed, the air is deflated by the inflation and deflation mechanism 2, and then the whole device is withdrawn from the uterine cavity.

Wherein, the sealing film layer 11a of the sealing end 11 of the main silicone tube 1 has a thickness smaller than that of the tube wall 13, and is preferably designed to be as thin as possible. The sealing film layer 11a can be integrally molded directly when the main silicone tube 1 is prepared; it can also be bonded to the main silicone tube 1 with another layer of film after the main silicone tube 1 is formed into an open shape by pasting or hot-melting. The silicone tube 1 forms a sealing film layer 11a.

Specifically, in this embodiment, the inflation and deflation mechanism 2 includes a connecting pipe 21 and an inflatable bag 22, one end of the connecting pipe 21 is connected to the intake pipe 4 through the interface valve 42, and the other end is connected to the air intake pipe 4. The inflatable bag 22 is connected; the inflatable bag 22 is provided with an inflation and deflation valve 23 , and the connecting pipe 21 is provided with an air pressure gauge 24 . When checking, the reading of the pressure gauge 24 can grasp the size of the intrauterine balloon 3 pressure, and if the air pressure is too large, the puerpera feels uncomfortable, and then can be properly deflated and decompressed by the inflation and deflation valve 23.

Specifically, as shown in FIG. 2 , in this embodiment, two inlet pipes 4 are provided on the pipe wall 13 of the main silicone tube 1 , and the two inlet pipes 4 communicate with each other and are respectively provided with vent holes 41 . Further, two air intake pipes 4 are distributed on the outer wall of the pipe wall 13 of the main silicone pipe 1 in a symmetrical manner around the circumference. It should be noted that, in some other embodiments, as shown in FIG. 3 , the air inlet pipe 4 can also be connected to the inner wall of the pipe wall 13 of the main silicone pipe 1. At this time, the vent hole 41 of the air inlet pipe 4 Pass through the tube wall 13 of the main silicone tube 1 and communicate with the inside of the balloon. Of course, it is conceivable that the air intake pipe 4 can also be directly opened in the pipe wall 13 of the main silicone pipe 1 . In addition, for the number of intake pipes 4, two are shown in this embodiment as an example. In other embodiments, only one intake pipe 4 may be provided, or more intake pipes may be provided. 4. When a plurality of intake pipes 4 are provided, these intake pipes 4 communicate with each other, and the plurality of intake pipes 4 can be distributed symmetrically or randomly.

Specifically, as shown in FIG. 2 , in this embodiment, the cross section of the intake pipe 4 is a part of a circular ring. In some other embodiments, the intake pipe 4 may also be configured to have a circular cross section.

In this embodiment, the open end 12 has a trumpet-shaped opening, so that detection instruments (such as a hysteroscope) can be inserted into the main silicone tube 1 more conveniently.

In another embodiment, the air pressure gauge 24 in the above-mentioned inflation and deflation mechanism 2 can be replaced with a flow meter, and the inflation bag 22 can be replaced with a liquid injector, and the inflation and deflation mechanism 2 can be used to pass liquid through the inlet The trachea 4 is injected into the balloon 3, and the injected liquid inflates the balloon 3 to achieve the purpose of dilating the uterine cavity, which can achieve the same effect.

The uterine cavity distension device provided above can inflate the uterine cavity by injecting gas or liquid to inflate the balloon, which can avoid the risk of water intoxication or embolism caused by the traditional method of inflating the uterus with water.

The uterine cavity distension device provided above can also be used for uterine cavity compression to stop bleeding. Intrauterine hemorrhage, especially postpartum hemorrhage, seriously threatens the life safety of puerpera. In clinical practice, drugs are usually used to promote uterine contraction and the uterine cavity is filled with gauze to compress the hemostasis. This method of hemostasis has disadvantages, specifically: gauze packing is difficult for hemostasis operation, and the force in the uterine cavity is uneven, which easily causes dead space, which leads to hemostasis failure. The clinical effect of relying solely on drugs to promote uterine contraction and hemostasis is also poor. However, the uterine cavity expansion device provided by the new embodiment of the present invention realizes compression and hemostasis of the uterine cavity by inflating the balloon, the force in the uterine cavity is uniform, and the pressure of the balloon on the uterine cavity can be adjusted. Furthermore, hemostatic drugs can also be coated on the outer surface of the balloon, which can realize drug hemostasis and compression hemostasis at the same time, and can be used for the treatment of intrauterine bleeding diseases. Furthermore, in order to monitor the hemostatic effect, the intrauterine hemostasis can be observed through hysteroscopy, and the hemostatic effect can be monitored in real time, which can effectively reduce the misjudgment of uterine bleeding and avoid life-threatening accidents such as maternal hemorrhage. Guaranteed the life safety of the puerpera.
