Description

Technical Field

[0001] This utility model relates to the field of hysterosalpingography tubes, and in particular to a leak-proof hysterosalpingography tube. Background Technology

[0002] Hysterosalpingography (HSG) is a medical examination method that involves injecting a high-density substance into the uterine cavity through the cervical canal. During the procedure, the contrast tube is a key medical device responsible for injecting the contrast agent into the uterine cavity, ensuring that the contrast agent can be distributed and visualized smoothly, which helps doctors understand the morphology and patency of the uterus and fallopian tubes.

[0003] The existing hysterosalpingography (HSG) tubes are made of silicone. Due to their long length, once inserted into the uterus, the tubes are prone to movement or rotation when contrast agents are introduced, which can affect the administration of the contrast agents and cause discomfort to the patient.

[0004] Therefore, it is necessary to propose a leak-proof hysterosalpingography tube to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a leak-proof hysterosalpingography (HSG) tube to address the problem that existing HSG tubes are made of silicone tubing, which, due to their long length, are prone to movement or rotation after being inserted into the uterus and contrast agent is introduced. This can affect the introduction of the contrast agent and cause discomfort to the patient.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a leak-proof hysterosalpingography tube, comprising a first tube and a second tube, wherein the second tube extends into the interior of the first tube, and one end of both the first tube and the second tube is connected to a conical opening;

[0007] An expansion sleeve is fitted on the outer side of the other end of the second pipe. The expansion sleeve is umbrella-shaped and elastic. The first pipe is fitted on the outside of the second pipe. The expansion sleeve has multiple air bladders inside, all of which are connected to the inside of the first pipe. The multiple air bladders are evenly arranged around the outside of the first pipe. The end of the expansion sleeve away from the conical opening is connected to the end of the second pipe.

[0008] Preferably, the radius of the end of the expansion sleeve near the conical opening is larger than the radius of the end away from the conical opening, and a groove is provided on the side of the expansion sleeve near the conical opening, with multiple airbags disposed in the groove.

[0009] Preferably, a plurality of spherical bags are fixed to the outside of the second pipe, and the interior of the plurality of spherical bags is connected to the interior of the first pipe.

[0010] Preferably, each of the multiple airbags has an embedded groove on the side near the conical opening, the embedded groove is connected to the interior of the corresponding airbag, and an intercepting membrane is fixed inside the embedded groove.

[0011] Preferably, multiple spherical bags are distributed at equal intervals along the length of the second pipe.

[0012] Preferably, a plurality of fixing posts are fixedly connected to the outer side of the second pipe, and one end of the plurality of fixing posts is fixedly connected to the inner wall of the first pipe.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. The tip of the expansion sleeve can be inserted into the patient's uterus. By introducing gas into the first channel, the gas can enter the interior of multiple balloons through the first channel, causing the balloons to inflate. The inflated balloons can support the elastic expansion sleeve, making the expansion sleeve larger and able to be fixed in the uterus, facilitating the introduction of contrast agent through the second channel. Because the expansion sleeve itself has an umbrella-shaped structure, the outer arc surface of the expansion sleeve will not cause harm to the person when it is inserted into the uterus. At the same time, when the gas is expelled, the expansion sleeve automatically contracts, making it easy to remove.

[0015] 2. As gas is introduced, it also enters the interior of the spherical bag, causing the bag to inflate. This allows the second tube to fit snugly against the person's body, increasing friction and preventing the device from moving or rotating during contrast agent administration.

[0016] 3. In the actual operation of this utility model, other liquids, such as cleaning fluid, can also be introduced into the first pipe. As the amount of liquid gradually increases, the internal pressure of the first pipe increases, and the liquid will squeeze the intercepting membrane, eventually causing the intercepting membrane to rupture. At this time, the liquid can be smoothly discharged from the first pipe without affecting the delivery of contrast agent in the second pipe. Attached Figure Description

[0021] This utility model provides, for example Figures 1-3The leak-proof hysterosalpingography tube shown includes a first tube 1 and a second tube 2. The second tube 2 extends into the interior of the first tube 1. Specifically, the radius of one end of the second tube 2 gradually decreases and extends into the interior of the first tube 1, so that the first tube 1 can be fitted onto the outside of the second tube 2.

[0022] Furthermore, multiple fixing posts 9 are fixedly connected to the outside of the second pipe 2. One end of each fixing post 9 is fixedly connected to the inner wall of the first pipe 1. The first pipe 1 and the second pipe 2 are used to transport gas and contrast agent, respectively. The multiple fixing posts 9 can firmly fix the second pipe 2 inside the first pipe 1. While transporting gas, the first pipe 1 can protect the outside of the second pipe 2. Even if the second pipe 2 is ruptured, the contrast agent will not overflow, thus improving the leak prevention effect.

[0023] An expansion sleeve 4 is fitted on the outer side of the other end of the second pipe 2. The expansion sleeve 4 is umbrella-shaped and elastic. The first pipe 1 is fitted on the outer side of the second pipe 2. Multiple airbags 6 are provided inside the expansion sleeve 4. The multiple airbags 6 are all connected to the interior of the first pipe 1 and are evenly arranged around the outer side of the first pipe 1. The end of the expansion sleeve 4 away from the conical opening 3 is connected to the end of the second pipe 2. The radius of the end of the expansion sleeve 4 near the conical opening 3 is larger than the radius of the end away from the conical opening 3. A groove 5 is provided on the side of the expansion sleeve 4 near the conical opening 3, and the multiple airbags 6 are disposed in the groove 5.

[0024] The tip of the expansion sleeve 4 can be inserted into the patient's uterus. By introducing gas into the first tube 1, the gas can enter the interior of multiple airbags 6 through the first tube 1, causing the multiple airbags 6 to inflate. The inflated airbags 6 can support the elastic expansion sleeve 4, making the expansion sleeve 4 larger and able to be fixed inside the uterus, facilitating the introduction of contrast agent through the second tube 2. Since the expansion sleeve 4 itself has an umbrella-shaped structure, the outer arc surface of the expansion sleeve will not cause harm to the person when it is inserted into the uterus. At the same time, when the gas is expelled, the expansion sleeve 4 automatically contracts, making it easy to remove.

[0025] Multiple spherical bags 7 are fixed on the outside of the second pipe 2. The interior of the multiple spherical bags 7 is connected to the interior of the first pipe 1. The multiple spherical bags 7 are distributed at equal distances along the length of the second pipe 2.

[0026] At the same time as the gas is input, the gas also enters the interior of the spherical bag 7, causing the spherical bag 7 to inflate, so that the second tube 2 can fit into the body of the person, increasing friction and preventing the device from moving or rotating when the contrast agent is input.

[0027] Furthermore, one end of the first pipe 1 and the second pipe 2 are connected to a conical opening 3, and each of the multiple airbags 6 has an embedded groove on the side near the conical opening 3. The embedded groove is connected to the interior of the corresponding airbag 6, and an intercepting membrane 8 is fixed inside the embedded groove.

[0028] In the actual operation of this utility model, other liquids, such as cleaning fluid, can also be introduced into the first pipe 1. As the amount of liquid gradually increases, the internal pressure of the first pipe 1 increases, and the liquid will squeeze the intercepting membrane 8, eventually causing the intercepting membrane 8 to rupture. At this time, the liquid can be smoothly discharged from the first pipe 1 without affecting the delivery of contrast agent in the second pipe 2.
