Description

Technical Field

[0001] This invention relates to the field of vaginal examination auxiliary instruments, specifically to a sealing and leak-proof device for vaginal hydrocontrast imaging. Background Technology

[0002] Hysterosalpingography (HSG) is an imaging technique used to examine the female reproductive system (mainly the vagina). By injecting sterile fluid (usually saline) into the vagina, imaging techniques such as ultrasound are used to clearly display the shape and structure of the vagina, helping doctors to determine if any abnormalities are present.

[0003] Vaginal hydroponic imaging requires sealing the vaginal opening to prevent the flow of sterile fluid, and using sterile fluid to inflate the vagina so that imaging instruments such as ultrasound probes can observe the vagina.

[0004] Currently, in clinical practice, fluid-filled balloons are generally used for vaginal occlusion. This requires real-time monitoring of the amount of sterile fluid injected using an ultrasound probe. However, the expanded spherical occlusion device occupies a significant amount of vaginal space, affecting the scope of vaginal examination. Existing technology also limits the deflection angle of the ultrasound probe, impacting its examination range. Furthermore, insufficient adhesion between the balloon and the vaginal wall can lead to leakage of sterile fluid, preventing the vagina from being fully filled. All of these factors can affect the assessment of vaginal lesions to varying degrees.

[0005] Therefore, a sealing and leak-proof device for vaginal hydrography was proposed. Summary of the Invention

[0006] The present invention aims to provide a sealing and leak-proof device for vaginal hydroponic imaging that is easy to determine the irrigation status, has a smaller obstruction area to the vaginal wall, and can improve the probe's examination range.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] This invention provides a sealing and leak-proof device for vaginal hydrocontrast imaging, comprising a sealing ring, a probe inlet / outlet tube, and an annular piece sealingly connected between the sealing ring and the probe inlet / outlet tube. The sealing ring includes an outer air ring and an inner air ring with their end faces connected. The centerlines of the outer air ring and the inner air ring coincide, and an annular groove is formed between the outer and inner air rings. An air nozzle is connected to the end face of the outer air ring away from the inner air ring. The air nozzle is used to connect to an inflation hose or an inflation ball.

[0009] Preferably, an injection tube is connected to the annular plate, and a first check valve is provided at the end of the injection tube near the inner air ring.

[0010] Preferably, the probe inlet / outlet tube is an elastic tube with a duckbill valve at one end.

[0011] Preferably, the outer peripheral surface of the probe inlet / outlet tube away from the inner gas ring is provided with a convex ring.

[0012] Preferably, the inner wall surface of the probe inlet / outlet tube near the duckbill valve end is provided with an inwardly convex sealing ring plate perpendicular to the axis of the probe inlet / outlet tube. The inwardly convex sealing ring plate is a thin annular piece with a central insertion hole, the center of which coincides with the axis of the probe inlet / outlet tube.

[0013] Preferably, the inner wall of the duckbill valve and the surface of the inner convex sealing ring are pre-coated with a lubricant such as paraffin oil.

[0014] Preferably, a conduit is inserted into the probe inlet / outlet tube.

[0015] Preferably, the outer diameters of the inner and outer air rings are equal, and the wall thickness of the inner air ring is less than or equal to the wall thickness of the outer air ring.

[0016] Preferably, the outer circumferential surface of the inner air ring is provided with a sealing ring, which is a thin annular sheet concentric with the inner air ring.

[0017] Preferably, the outer circumferential surface of the probe inlet / outlet tube is provided with an irrigation mark indicating the extent of probe inlet / outlet tube extension. The irrigation mark is obtained through a certain amount of irrigation experiments, that is, when the irrigation mark on the probe inlet / outlet tube extends beyond the end face of the outer air ring, the vaginal wall can be expanded to the ideal examination state by physiological saline.

[0018] Preferably, the air nozzle is a rigid tube or a flexible tube.

[0019] Preferably, the annular plate is funnel-shaped, with the small-hole end fixedly and sealed to the outer circumferential surface of the probe inlet / outlet tube, and the large-hole end fixedly and sealed to the inner air ring.

[0020] Preferably, the sealing and leak-proof device is made of silicone in one piece.

[0021] Due to the adoption of the above technical solutions, the advantages of this invention are as follows:

[0022] 1. The thickness of the inner air ring placed at the vaginal opening provided by the present invention is significantly smaller than the thickness of the spherical sealing structure, thus the present invention covers a smaller area of ​​the vaginal wall.

[0023] 2. During the process of inserting the probe into the probe inlet and outlet tube for inspection, the annular plate is easy to bend and deform, thus the probe can be easily adjusted in all directions and at large angles. In addition, the sealing and leak-proof device provided by this invention has a small obstruction range on the vagina, which is beneficial to significantly improve the probe inspection range.

[0024] 3. The present invention can determine the degree of perfusion by observing whether the perfusion mark extends out of the outer air ring, making it easy to judge the perfusion status and more accurate in determining the degree of perfusion, reducing or eliminating the need to determine the degree of perfusion with the assistance of an ultrasonic probe.

[0025] 4. The present invention improves the leakage prevention effect by setting an inner convex sealing ring piece and a sealing ring piece that are easily deformed under pressure. Attached Figure Description
