Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a fallopian tube catheter for hydrotubation and fallopian tube angiography. Background Art

[0002] At present, the main examinations for the patency of the fallopian tubes include: hysterosalpingography, hysterosalpingography, hysterosalpingography, hysteroscopy and laparoscopy. Among them, hysteroscopy and laparoscopy need to be performed under general anesthesia in the operating room, which are complicated to operate, expensive, have anesthesia risks, are more traumatic, and are prone to postoperative adhesions. Hysterosalpingography needs to be performed under X-ray, and the patient's body is exposed to radiation hazards. In addition, iodized oil has the risk of allergies, and iodized oil is not easily metabolized from the human body, so at least 3 months of contraception is required before preparing for pregnancy again.

[0003] In comparison, hysterosalpingography is more economical, simple and easy to operate, causes less harm to the patient's body, and the accuracy of the test results is comparable to that of hysterosalpingography. It has now become the preferred examination item for screening the patency of the fallopian tubes. Patients with tubal infertility require a disposable fallopian tube perfusion and angiography tube during the examination of the patency of the fallopian tubes. In addition, this operation can also clear and treat patients with mild fallopian tube obstruction.

[0004] However, the currently used fallopian tube perfusion and angiography tubes are not easy to judge whether the fallopian tubes are unobstructed during the examination process, especially when judging whether the fallopian tubes are unobstructed or not, the judgment can only be based on the feel of the injector, which is not very objective. Moreover, after detecting fallopian tube blockage, it is also impossible to directly determine which side of the fallopian tube is blocked, and it is impossible to accurately clear the blocked fallopian tube. Utility Model Content

[0005] The utility model aims to provide a fallopian tube perfusion and salpingography catheter, which has the advantages of simple and reasonable structure, easy operation during use, and can more accurately judge whether the fallopian tube is unobstructed. In addition, it can accurately locate the blocked fallopian tube in the case of fallopian tube obstruction and perform dredging treatment on the blocked fallopian tube.

[0006] In order to achieve the above purpose and other related purposes, the utility model provides the following technical solutions:

[0007] A fallopian tube catheter for hydrotubation and salpingography, comprising

[0008] A liquid injection tube, wherein the liquid injection port and the liquid outlet are provided on the liquid injection tube, and a micro pressure sensor is provided at the end of the liquid injection tube near the liquid outlet;

[0009] An air injection tube, the air injection tube being fixed on the liquid injection tube; the air injection tube having an air inlet at one end and a blocking portion for blocking the fallopian tube opening at the other end; in an inflated state, the blocking portion is turned outward toward a side away from the liquid injection tube;

[0010] An operating wire is arranged on the gas injection tube and one end of the operating wire is connected to the blocking part. Pulling the operating wire can adjust the eversion angle of the blocking part.

[0011] Through the above technical scheme, liquid is injected through the injection port of the injection tube, and the liquid flows into the uterine cavity through the liquid outlet hole; air is injected into the air injection tube through the air intake, and the blocking part is everted close to the fallopian tube opening, and the eversion angle of the blocking part is adjusted by pulling the operating wire, so that the blocking part blocks the fallopian tube opening; when the liquid is continuously injected into the uterine cavity, the micro pressure sensor is used to monitor the pressure in the uterine cavity, so as to determine whether the unblocked fallopian tube is blocked, thereby improving the accuracy and objectivity of diagnosis.

[0012] In one embodiment of the present invention, the blocking portion includes an active air tube connected to the air injection tube and a balloon connected to the active air tube.

[0015] In the uninflated state, the two active tracheas are moved closer to the middle, and the two balloons are deflated and overlapped;

[0016] In the inflated state, the two active tracheas are respectively turned outward to both sides, and the two balloons are separated after being spherical.

[0017] Through the above technical solution, the two blocking parts respectively control the opening or closing of the fallopian tubes on both sides; thus avoiding the discomfort caused by the frequent rotation of the injection tube when only one blocking part controls the opening or closing of the fallopian tubes on both sides;

[0018] In the uninflated state, the two active tracheae move closer to the middle, the two balloons overlap in a deflated state, and the overall end is tapered, which makes it easier to insert the catheter into the uterine cavity and easier for doctors to operate the lower tube, making it more comfortable to use.

[0019] After the catheter is inserted into the uterine cavity, air is ventilated into the air injection tube. After the two active air tubes are ventilated, they are respectively turned outward to both sides. After the two balloons are ventilated, they become spherical and are separated by the traction of the two active air tubes. The two inflated blocking parts are respectively directed toward the two fallopian tubes, thereby facilitating the two blocking parts to independently control the openness or closure of the two fallopian tubes.

[0025] Through the above technical solution, the rubber ring is arranged at the external cervical os, thereby preventing the tube from falling out due to excessive uterine cavity pressure.

[0026] In one embodiment of the utility model, a pressure value feedback screen electrically connected to a micro pressure sensor is provided on the injection tube near one end of the injection port, and a timer is connected to one side of the pressure value feedback screen.

[0027] Through the above technical solution, the time can be monitored while monitoring the intrauterine pressure, thereby reducing errors and increasing diagnostic accuracy and objectivity.

[0028] In one embodiment of the present invention, a plurality of liquid outlet holes are formed on the side wall of the liquid injection tube.

[0029] Through the above technical solution, the injection flow rate in the uterine cavity is ensured.

[0030] In one embodiment of the present invention, an air injection pipe and a blocking portion are provided on one side of the liquid injection pipe.

[0031] Through the above technical scheme, the eversion angle of the blocking part is adjusted by pulling the operating wire, so that the blocking part blocks the opening of the fallopian tube; when the fluid is continuously injected into the uterine cavity, the micro pressure sensor is used to monitor the pressure in the uterine cavity, so as to determine whether the unblocked fallopian tube is blocked; according to the specific situation, the openings of the fallopian tubes on both sides are blocked in turn with the blocking part, and then the injection tube is rotated to turn the blocking part to the fallopian tube close to the other side and block the opening of the fallopian tube, and when the fluid is continuously injected into the uterine cavity, the micro pressure sensor is used to monitor the pressure in the uterine cavity at this time, so as to analyze the pressure values ​​in the uterine cavity twice, and then determine the patency of the fallopian tubes on both sides; improve the accuracy and objectivity of diagnosis; in addition, if one side of the fallopian tube is blocked, the opening of the fallopian tube on the unobstructed side can be blocked by the blocking part, and the fallopian tube on the blocked side can be dredged and treated by continuously injecting fluid into the uterine cavity.

[0032] As described above, the fallopian tube catheter and salpingography catheter of the utility model has the following beneficial effects:

[0033] 1. The two blocking parts are used to control the opening or closing of the two fallopian tubes respectively.
