Description

Technical Field

[0001] The utility model relates to the technical field of medical teaching aids, in particular to a hysterosalpingography operation simulation teaching aid. Background Art

[0002] Contrast agents are chemicals injected into human tissues or organs to enhance imaging. These agents have a higher or lower density than surrounding tissue, creating a contrast that allows for the visualization of images using certain instruments. Examples include iodine preparations and barium sulfate, commonly used in X-ray observation.

[0003] Hysterosalpingography involves injecting a contrast agent into the uterine cavity through the cervix. This creates a clear artificial contrast with surrounding tissue on X-rays, allowing visualization of the tubal lumen and understanding the conditions within the uterus and fallopian tubes. This procedure not only indicates tubal patency and identifies any obstructions, but also allows visualization of the uterine cavity. This procedure is relatively safe, requires no anesthesia, and is painless, making it more acceptable to patients.

[0004] Doctors' low proficiency in hysterosalpingography can easily lead to pain during hysterosalpingography. Therefore, designing a teaching aid for hysterosalpingography simulation training has become an urgent problem in the field of medical teaching aid technology. Utility Model Content

[0005] The purpose of the utility model is to provide a hysterosalpingography operation simulation teaching aid, which can be used by doctors to perform hysterosalpingography simulation training on a uterine mold, thereby improving the doctors' hysterosalpingography proficiency, reducing the occurrence of hysterosalpingography pain caused by actual work, and recovering contrast agent through the liquid collection cavity of the liquid reservoir.

[0006] In order to achieve the above-mentioned purpose of the invention, the present invention adopts the following technical solutions:

[0007] A hysterosalpingography operation simulation teaching aid includes a uterine mold and a liquid reservoir. The uterine mold includes a uterine body, fallopian tubes, ovaries, cervix and vagina. The inner cavity of the uterus is connected to the vagina through the cervical canal opening. The inner cavity of the uterus is connected to two fallopian tubes respectively. The fallopian tube is provided with a liquid outlet at one end close to the ovary. The liquid reservoir is provided with a liquid collecting cavity. The liquid outlet and the liquid collecting cavity are connected so that contrast agent flows from the vagina to the liquid outlet and is collected in the liquid collecting cavity.

[0008] Compared with the existing technology, the hysterosalpingography operation simulation teaching aid adopting the above technical solution has the following beneficial effects:

[0009] 1. The utility model adopts the hysterosalpingography operation simulation teaching aid. The uterine mold imitates the human uterus. Doctors can perform hysterosalpingography simulation training on the uterine mold, thereby improving the doctor's hysterosalpingography proficiency and reducing the occurrence of hysterosalpingography pain in actual work.

[0010] 2. During the hysterosalpingography simulation operation, the doctor injects the contrast agent into the inner cavity of the uterus from the vagina. The contrast agent will flow through the two fallopian tubes to the liquid outlet, and the excess contrast agent will be collected in the liquid collection cavity of the reservoir for easy recovery of the contrast agent.

[0011] Preferably, the vagina and cervix are made of soft rubber. The vagina and cervix are elastic, so that the uterus mold can be more similar to the human uterus, and the doctor training effect is better.

[0012] Preferably, the uterus and fallopian tubes are made of translucent plastic, which is convenient for doctors to observe and use in teaching.

[0013] Preferably, the vagina and cervix are integrally formed, the uterine body, fallopian tubes, and ovaries are integrally formed, and the cervix is threadedly connected to the uterine body. The cervix and uterine body are detachably connected, so if the vagina and cervix of the uterine mold are damaged due to improper operation by the doctor, the vagina and cervix of the uterine mold can be replaced and continued use can be achieved.

[0014] Preferably, the reservoir is provided with a water purification chamber containing purified water. A pump gun is externally connected to the reservoir. The pump gun can be similar to an existing high-pressure water gun. The pump gun is used to spray the purified water from the water purification chamber. A reference to an existing high-pressure water gun (manufactured by Suzhou Kaizhuosheng Hardware & Electrical Equipment Co., Ltd.) can be used. After the hysterosalpingography simulation procedure is completed, the physician inserts the muzzle of the pump gun into the vagina and flushes the uterine mold with the pump gun. The purified water cleans the uterine mold and is then collected in the liquid collection chamber for easy waste disposal.

[0015] Preferably, transparent windows are provided on the side walls of the liquid collecting chamber and the water purification chamber, and the transparent windows are strip-shaped, and the length direction of the transparent windows is the same as the height direction of the liquid reservoir. The liquid volume in the liquid collecting chamber and the water purification chamber can be viewed through the transparent windows, making it convenient for doctors to replenish the water purification chamber and drain the liquid collecting chamber.

[0016] Preferably, a first sensor is provided on the side wall of the liquid collecting chamber, and a first indicator light is provided on the outer wall of the liquid reservoir. The first indicator light is electrically connected to the first sensor. When the liquid level in the liquid collecting chamber rises above the first sensor, the first indicator light is triggered to illuminate. The first sensor detects the liquid level in the liquid collecting chamber. When the liquid level in the liquid collecting chamber is excessive, the first indicator light alerts the doctor to drain the liquid collecting chamber promptly.

[0017] Preferably, a second sensor is provided on the lower side wall of the water purification chamber, and a second indicator light is provided on the outer wall of the liquid reservoir. The second indicator light is electrically connected to the second sensor.

The fluid outlet 16 and the fluid collection chamber 21 are connected, allowing the contrast agent to flow from the vagina 13 to the fluid outlet 16 and be collected in the fluid collection chamber 21. The uterine mold 1 simulates the human uterus. Doctors can use the uterine mold 1 to perform hysterosalpingography simulation training, improve their proficiency in hysterosalpingography, and reduce the occurrence of pain caused by hysterosalpingography in actual work. During the hysterosalpingography simulation operation, the doctor injects contrast agent into the inner cavity of the uterine body 11 from the vagina 13. The contrast agent will flow through the two fallopian tubes 14 to the liquid outlet 16, and the excess contrast agent will be collected in the liquid collecting cavity 21 of the reservoir 2 for easy recovery of the contrast agent.

[0027] The vagina 13 and the cervix 12 are made of soft rubber. The vagina 13 and the cervix 12 are elastic, so that the uterus mold 1 can be more similar to the human uterus, and the doctor training effect is better.
