Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a hysterography tube. Background Art

[0002] Hysterography is a medical examination method that injects a high-density substance into the uterine cavity through the cervical canal. During the hysterography process, the hysterography tube, as a key medical device, is responsible for injecting the contrast agent into the uterine cavity, ensuring that the contrast agent can be smoothly distributed and developed, so as to help doctors understand the morphology and patency of the uterus and fallopian tubes.

[0003] The existing Chinese patent, publication number: CN 204246660 U discloses a hysterosalpingography tube, including a tube, the interior of which is divided into an airbag channel and an injection channel, the end of the airbag channel is provided with an airbag, and the front end is provided with an airbag channel plug. The closest distance between the end of the injection channel and the airbag after expansion is 1 cm, and a hole is opened in the center of the end of the end, and an injection channel plug is provided at the front end, and the diameter of the hole is 1.1 mm. The utility model can avoid the problem that the end of the injection channel is too long, causing the radiography tube to press against one side of the uterine horn, so that the fallopian tube that may be visualized is not visualized, resulting in a false positive manifestation of one side of the fallopian tube occlusion.

[0004] The hysterography tube in the above patent, when the tube is located inside the uterine cavity, the structure of the hysterography tube is likely to cause discomfort to the cervix, and when injecting contrast agent, the discharge position and discharge angle of the contrast agent cannot be adjusted, so that the distribution effect of the contrast agent is uneven, affecting the imaging quality. In addition, for different patients, the fitting state of the contrast catheter cannot be adjusted, which affects the airtight sealing effect of the balloon, so that the contrast agent is likely to leak out of the uterine cavity. Therefore, a hysterography tube is proposed to address the above problems. Summary of the invention

[0005] The problem solved by the present invention is to provide a hysterography tube with a simple structure and multiple functions. When in use, it can have a good sealing effect on the cervix, thereby effectively preventing the contrast agent from leaking out of the uterine cavity. At the same time, it can reduce the discomfort caused by the contrast agent to the inner wall of the uterine cavity during discharge, making the contrast agent discharge more uniform, thereby effectively improving the imaging quality of the uterine cavity and fallopian tubes.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Specific examples are given below.

[0037] See also Figure 1 to Figure 12A uterine radiography tube includes a radiography catheter 1, wherein a liquid injection branch 2 is fixedly installed at the center of one end of the radiography catheter 1, and a liquid injection valve 3 is connected and installed on one side of the outside of the radiography catheter 1, and a liquid injection terminal 4 is connected and installed at one end of the liquid injection valve 3, and an expansion component 8 is arranged at the outside of the center of one end of the radiography catheter 1, and the expansion component 8 is located on the outside of the liquid injection branch 2, and a limit component 9 is arranged on the outside of the liquid injection branch 2, and the limit component 9 is convenient for storing the expansion component 8, thereby improving the convenience of storage. A guide component 6 is arranged at the center of the interior of the radiography catheter 1, and the guide component 6 passes through the liquid injection branch 2 and is connected to the outside, and a liquid spray component 7 is arranged at the center of the other end of the radiography catheter 1, and the liquid spray component 7 can effectively prevent the radiography catheter 1 from impacting the inner wall of the uterus when discharging contrast agent, and can also make the contrast agent discharge more uniform. The guide component 6 facilitates the adjustment of the bending angle of the contrast catheter 1, thereby facilitating the conformation of the contrast catheter 1 to the inner wall of the uterus. After the contrast catheter 1 is located at a suitable position, the expansion component 8 facilitates the blocking of the cervix, and the injection valve 3 and the injection end 4 facilitate the injection of contrast agent into the injection branch 2. The contrast agent is filled in the uterine cavity through the contrast catheter 1 and the spray component 7, which facilitates the visualization of the uterine cavity and the fallopian tube.

[0038] The liquid spray assembly 7 includes an arc-shaped nozzle 71, which is fixedly installed at the center of the other end of the angiography catheter 1, and the interior of the arc-shaped nozzle 71 is connected to the interior of the angiography catheter 1. A protective frame 77 is provided at the center of the outside of the arc-shaped nozzle 71, and a baffle plate 79 is provided at the center of the inner side of the protective frame 77. An arc-shaped diverter seat 710 is fixedly installed at the center of the end face of the baffle plate 79, and a conical dispersion hole 711 is opened at the center of the end face of the baffle plate 79, and the conical dispersion hole 711 passes through the arc-shaped diverter seat 710. When the contrast agent is delivered to the arc nozzle 71 through the contrast catheter 1, it can be delivered to the baffle 79 at the center of the inner side of the protective frame 77 through the arc nozzle 71, and part of the contrast agent can be diverted through the arc diverter seat 710, so that the contrast agent is diffused from the surface of the arc diverter seat 710 at different angles and filled in the inside of the uterine cavity. Moreover, part of the contrast agent is discharged through the conical dispersion holes 711. When the developer passes through the conical dispersion holes 711, it first flows through the narrow hole and then flows through the wide hole, which can effectively reduce the discharge speed of the contrast agent, thereby avoiding the discomfort caused by the contrast agent sprayed from one end of the arc nozzle 71 on the inner wall of the cervix, so that the contrast agent can be fully filled, which is convenient for the visualization of the uterine cavity and the fallopian tube.

Four adjusting struts 76 are fixedly installed on one end of the protective frame 77 close to the angiographic catheter 1, and the four adjusting struts 76 respectively pass through the gap between the first anti-slip plate 73 and the second anti-slip plate 74 and are fixedly connected to the outer walls of the four rotating balls 75. The first anti-slip plate 73 and the second anti-slip plate 74 can limit the rotating balls 75, and facilitate the rotating balls 75 to rotate inside the spherical groove 72. When the position of the angiographic catheter 1 is adjusted inside the cervix, the protective frame 77 can be driven to move. When the protective frame 77 contacts the inner wall of the cervix, due to the continuous movement of the angiographic catheter 1, the protective frame 77 can rotate inside the spherical rotating groove 72 by adjusting the rotating ball 75 on one side of the support rod 76, so that the protective frame 77 can rotate and contact with the inner wall of the cervix, which is convenient for adjusting the position of the angiographic catheter 1, avoiding scratching and damage between the protective frame 77 and the inner wall of the cervix, and reducing discomfort.

[0040] The outer wall of the baffle plate 79 is fixedly mounted with mounting arms 78, and the other ends of the outer walls of the four mounting arms 78 are fixedly connected to the inner wall of the protective frame 77. The mounting arms 78 can improve the connection tightness between the protective frame 77 and the baffle plate 79, making the structure of the baffle plate 79 more stable.

A retainer 89 is fixedly installed at a position between the second expansion balloon 88 and the first expansion balloon 86 in the interior of the contrast catheter 1. A third expansion balloon 810 is installed between the outer side of the retainer 89 and the inner wall of the contrast catheter 1. A third balloon water pipe 811 is connected and installed at one end of the third expansion balloon 810, and one end of the third balloon water pipe 811 is communicated with the interior of the second balloon water pipe 87. A second sealing end cap 84 is installed on one side of the exterior of the expansion terminal 83 through a plastic belt, and the inner center of the second sealing end cap 84 is fitted and connected with the inner wall of one end of the expansion terminal 83. By setting the second sealing end cap 84, one end of the expansion terminal 83 can be easily blocked, thereby preventing dust and impurities from entering the interior of the expansion terminal 83, and improving the safety and sanitation effect of use.

[0043] Among them, after the angiography catheter 1 is placed inside the uterine cavity, the second inflation balloon 88 and the first inflation balloon 86 are respectively located at the position of the internal os of the cervix, and the inflation liquid is transported to the inflation branch 82 on the end face of the sealing seat 81 through the inflation end 83, and is transported to the first balloon water tube 85 and the second balloon water tube 87 through the sealing seat 81. The first balloon water tube 85 can make the inflation liquid expand the first inflation balloon 86 to block the cervix, and the second balloon water tube 87 can make the inflation liquid expand the second inflation balloon 88 to block the cervix. By setting up double balloons, the effect of the airtight sealing can be effectively improved. At the same time, the inflation liquid flowing to the third inflation balloon 810 through the third balloon water tube 811 can expand and lift the third inflation balloon 810 on the outside of the retaining frame 89, so that the position of the retaining frame 89 can be maintained, thereby avoiding the contrast agent being blocked due to the bending of the angiography catheter 1 caused by the bending of the cervical os.
