Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a disposable pressure detection salpingography kit. Background Art

[0002] In the field of diagnosis and treatment of gynecological diseases, fallopian tube patency examination is one of the important means to assess female fertility. At the same time, fallopian tube obstruction unblocking treatment also brings hope of fertility to many patients. However, the current means of fallopian tube patency examination have significant defects, and there is a general lack of monitoring mechanism for the internal pressure of the uterus and fallopian tubes. During the unblocking treatment of fallopian tube obstruction, there is also no effective means of pressure monitoring and quantification. When doctors operate, they can only rely on personal feel and clinical experience to control the unblocking pressure, and it is difficult to form a unified treatment standard value. This situation leads to large differences in operations between different doctors, and the lack of objectivity and consistency in the examination and treatment results, which not only affects the accuracy of diagnosis and treatment, but also is not conducive to the exchange and promotion of medical technology. Therefore, there is an urgent need for a device that can realize pressure monitoring and quantification during fallopian tube examination and treatment to improve the standardization level of medical operations. Summary of the Invention

[0003] The purpose of the present invention is to provide a disposable pressure detection hysterosalpingography kit, which, through integrated pressure monitoring function and closed structure design, can realize real-time monitoring and precise control of the internal pressure of the uterus and fallopian tubes, thereby quantifying the means of fallopian tube examination and treatment, providing a unified and standardized pressure value reference for clinical operations, and improving the accuracy and consistency of examination and treatment.

[0004] In order to solve the above technical problems, the present invention provides a disposable pressure detection salpingography kit, which includes a catheter, a pressure measuring device, a Y-shaped connector, a dispenser, and a plug. The three interfaces of the Y-shaped connector are respectively connected to the catheter, the pressure measuring device, and the dispenser to form a complete pressure monitoring and drug delivery system.

[0005] Furthermore, the catheter is one of a hysterosalpingography balloon catheter, a dredging tube, and a microcatheter. Preferably, when a hysterosalpingography balloon catheter is used, it includes a catheter body, one end of the catheter body is provided with an injection hole, and a balloon is provided near the end of the injection hole. The other end of the catheter body is provided with an air flushing cavity and an injection cavity. The air flushing cavity is connected to the balloon for filling the balloon; the injection cavity is connected to the injection hole for injecting contrast agent or therapeutic drugs.

[0006] Furthermore, the pressure measuring device is a pressure gauge, which is connected to the catheter through a Y-type connector and can display the pressure value inside the uterus and fallopian tube in real time when injecting drugs or contrast agents, providing doctors with intuitive pressure monitoring data.

[0007] Furthermore, the Y-type connector is a Luer connector. As a standardized medical connector, the Luer connector achieves sealing through a threaded connection. The anti-detachment structure of its port can ensure that the components are firmly connected under pressure to prevent them from falling off.

[0008] Furthermore, the hysterosalpingography balloon catheter includes a catheter body, one end of which is provided with an injection hole, a balloon is provided on the catheter body at the end with the injection hole, and the other end of the catheter body is provided with an air flushing cavity and an injection cavity, the air flushing cavity is connected to the balloon, and the injection cavity is connected to the injection hole.

[0009] Furthermore, the hysterosalpingography kit also includes a plug, which is arranged on the catheter body. When the catheter body is inserted into the uterine cavity, the balloon can block the internal opening of the cervix and the plug blocks the external opening of the cervix, ensuring that no pressure is leaked during inspection and treatment.

[0010] Furthermore, the dispenser is provided with a locking device, which can prevent the piston on the dispenser from rebounding.

[0011] Furthermore, the locking device includes a limiting mechanism arranged on the curled edge of the dispenser outer shell and a ratchet arranged on the core rod of the dispenser. The limiting mechanism can fix the position of the piston in the outer shell through the ratchet, so that when injecting various types of examination and treatment drugs, the internal pressure of the uterine fallopian tube can be fixed without the doctor continuously applying manual pressure, thereby avoiding reflux of drugs and pressure relief.

[0012] Furthermore, the limiting mechanism includes a limiting body, a spring, a first limiting block, and a second limiting block. The limiting body is provided with a cavity with an open end. The spring and the first limiting block are arranged in the cavity of the limiting body. One end of the spring abuts against the inner wall of the upper end of the cavity, and the other end of the spring abuts against the first limiting block. The second limiting block is arranged at the open end of the cavity through a slot. When in use, the second limiting block is pulled open, and the elastic force of the spring pushes the first limiting block to pop out. The first limiting block cooperates with the ratchet to lock the piston.

[0013] The present invention monitors the internal pressure of the uterus and fallopian tubes in real time through a pressure gauge, converting the operation that originally relied on the doctor's feel and experience into objective and quantitative data, so that the pressure values during fallopian tube examination and treatment can be accurately read, providing a reliable basis for clinical diagnosis and treatment. Standardized operations provide unified pressure standard values, reducing operational differences between different doctors, promoting the standardization of fallopian tube examination and treatment techniques, and facilitating the exchange and promotion of medical technology. The double-sealed structure of the balloon sealing the internal cervical os and the plug sealing the external cervical os, combined with the anti-detachment sealing design of the Luer connector, ensures that pressure will not leak during the examination and treatment process, ensuring the accuracy of pressure monitoring and the treatment effect. The locking device of the dispenser can fix the piston position, avoiding the doctor from manually pressurizing for a long time, reducing the doctor's operating burden, and at the same time preventing the reflux of the medicine and pressure relief, thereby improving the stability and efficiency of the operation.

For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0020] The present invention is further described in detail below with reference to the accompanying drawings.

[0021] like Figures 1 to 4 As shown, the disposable pressure detection salpingography kit includes a catheter 1, a pressure measuring device 2, a Y-type connector 3, a dispenser 4, and a plug 5. The three interfaces of the Y-type connector 3 are respectively connected to the catheter 1, the pressure measuring device 2, and the dispenser 4 to form a complete pressure monitoring and drug delivery system.

[0022] like Figure 7 、 Figure 8 As shown, the catheter 1 is one of the hysterosalpingography balloon catheter 11, the dredging tube 12, and the microcatheter 13. Preferably, when the hysterosalpingography balloon catheter is used, it includes a catheter body, one end of the catheter body is provided with an injection hole 112, and an end near the injection hole 112 is provided with a balloon 113, and the other end of the catheter body 111 is provided with an air flushing cavity 114 and an injection cavity 115. The air flushing cavity 114 is connected to the balloon 113 for filling the balloon; the injection cavity 115 is connected to the injection hole 112 for injecting contrast agent or therapeutic drugs.

[0023] The pressure measuring device 2 is a pressure gauge connected to the catheter via a Y-type connector. It can display the pressure value inside the uterus and fallopian tube in real time when injecting drugs or contrast agents, providing doctors with intuitive pressure monitoring data.

[0024] like Figure 10As shown, the Y-type connector 3 is a Luer connector. As a standardized medical connector, the Luer connector is sealed by a threaded connection. The anti-detachment structure of its port can ensure that the components are firmly connected under pressure to prevent them from falling off.

[0025] like Figure 9 As shown, the hysterosalpingography kit also includes a plug 5, which is provided with a through hole. The catheter body 111 passes through the through hole on the plug 5. The plug 5 can slide on the catheter body 111. When the catheter body is inserted into the uterine cavity, the balloon 113 can block the internal opening of the cervix, and the plug 5 blocks the external opening of the cervix, ensuring that no pressure leaks during inspection and treatment.

[0026] like Figure 5 、 Figure 6 As shown, the dispenser 4 is equipped with a locking device 41, which prevents the piston on the dispenser 4 from rebounding. The locking device 41 includes a limiting mechanism 42 provided on the curled edge of the dispenser's outer shell and a ratchet 43 provided on the core rod of the dispenser 4. The limiting mechanism 42, through the ratchet 43, can fix the position of the piston within the outer shell. Therefore, when injecting various examination and treatment drugs, the internal pressure of the uterus and fallopian tube can be maintained without the doctor having to continuously apply manual pressure, thus preventing drug backflow and pressure release. The limiting mechanism 42 includes a limiting body 421, a spring 422, a first limiting block 423, and a second limiting block 424. The limiting body 421 is provided with a cavity 425 with an open end. The spring 422 and the first limiting block 423 are arranged in the cavity 425 of the limiting body 421. One end of the spring 422 abuts against the inner wall of the upper end of the cavity 425, and the other end of the spring 422 abuts against the first limiting block 423. The second limiting block 424 is arranged at the open end of the cavity 425 through a slot. When in use, the second limiting block 424 is pulled open, and the elastic force of the spring pushes the first limiting block to pop out. The first limiting block cooperates with the ratchet to lock the piston.

[0027] When using the disposable pressure-detecting hysterosalpingography kit of the present invention for fallopian tube examination or treatment, the user first selects an appropriate catheter type, such as a hysterosalpingography balloon catheter, based on actual needs. The catheter is then slowly inserted into the uterine cavity through the vagina. Air is then inflated into the balloon via the inflating chamber, filling it and sealing the internal cervical os. The plug (made of a soft material) at the rear of the balloon is then pushed, its tapered shape conforming to the curve of the external cervical os. This plug is then pushed along the catheter, pressing against the external cervical os, achieving a double seal of the cervix without leaking pressure. Connect one end of the Y-connector to the catheter, and the other end to the pressure gauge of the pressure measuring device and the dispenser. Fill the dispenser with an appropriate amount of contrast agent or therapeutic medication and push the dispenser plunger to inject. The pressure gauge displays the real-time pressure reading inside the uterus and fallopian tubes. When the desired pressure is reached, the dispenser's locking mechanism, through the interaction of a stopper and ratchet, secures the piston position, maintaining stable pressure and preventing medication backflow and pressure loss. Based on the pressure reading on the pressure gauge and clinical experience, the physician can accurately determine the patency of the fallopian tubes and initiate effective unblocking treatment. The present invention is not limited to the above-mentioned specific implementation methods. Various changes made by ordinary technicians in this field based on the above-mentioned concept without creative work are all within the scope of protection of the present invention.
