Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, and in particular relates to a vaginal irrigation device. Background Technology
[0002] Vaginal douches, as an important medical device in modern gynecological diagnosis and treatment systems, have gained widespread recognition in the medical community both domestically and internationally for their clinical application value. Vaginal douches are commonly used medical devices in gynecological care, serving to clean the vaginal area with controlled douche solutions, assisting in the treatment of infections or maintaining local hygiene. As a common gynecological care method, vaginal douches play a vital role in both clinical treatment and daily health maintenance.
[0003] Currently, the spray nozzles of vaginal douches used in hospitals are all fixed-size rigid small holes. This design is not flexible enough, as it cannot automatically adjust the water flow direction and pressure. For example, when encountering deeper areas of the vagina or areas with folds, the water flow is easily unevenly distributed, and some corners are not cleaned. Especially when the patient is lying down or changing position, the water pressure will be significantly reduced, which makes it neither clean enough nor achieve the treatment requirement of thorough cleaning.
[0004] Therefore, we provide a vaginal irrigation device to solve the problems mentioned above. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a vaginal irrigation device, including a delivery pipe for conveying irrigation fluid, with irrigation pipes and a storage tank for storing irrigation fluid connected to both ends of the delivery pipe; a mesh tube is rotatably arranged on the inner wall of the irrigation tube along its circumference, and an impeller is fixed at one end of the mesh tube near the delivery pipe, the rotation axis of the impeller coinciding with the rotation axis of the mesh tube; several diversion holes are evenly distributed in a circumferential array on the circumferential side of the irrigation tube, and the diversion holes are arranged on the rotation path of the mesh on the mesh tube; as the diversion holes gradually move away from the inner wall of the irrigation tube, their inner diameter gradually decreases, and the degree of change of the inner diameter of different diversion holes is different.
[0006] The present invention is further configured such that the angle at which the diversion hole retracts from the inner wall of the flushing pipe toward the inner wall of the flushing pipe is between 0° and 45°.
[0007] The present invention is further configured such that the inner diameter of the diversion hole at the end near the inner wall of the flushing pipe is the same as the inner diameter of the mesh hole of the mesh pipe.
[0008] The present invention is further configured such that an elastic diaphragm is sealed to the end of the flushing pipe away from the delivery pipe, and the diameter of the elastic diaphragm when it is stretched and bulged is greater than the diameter of the flushing pipe.
[0009] The present invention is further provided that a baffle is fixed at one end of the conveying pipe connected to the rinsing pipe to prevent splashing of used rinsing liquid.
[0010] The present invention is further configured such that a miniature water pump is provided at the end of the delivery pipe away from the rinsing pipe, and the pumping end of the miniature water pump is inserted into the rinsing liquid inside the storage tank.
[0011] The present invention has the following beneficial effects: 1. The present invention provides multiple diversion holes of different sizes on the periphery of the flushing tube. The inner diameter of the diversion holes gradually decreases from near the inner wall of the flushing tube to away from the inner wall of the flushing tube. The further inward the diversion holes shrink, the greater the water flow velocity of the water outlet holes. Consequently, the flushing force of the flushing liquid flowing out of the flushing tube is also different. The lower the water flow velocity, the weaker the force, resulting in a gentler flush. The higher the water flow velocity, the stronger the force, which can flush away stubborn bacteria and improve the efficiency of vaginal flushing.
[0012] 2. This utility model uses the water flow of the flushing fluid to drive the impeller to rotate, which in turn drives the mesh tube to rotate, so that the mesh on the mesh tube alternately aligns with the diversion hole on the flushing tube. When there is an overlap between the mesh and the diversion hole, the flushing fluid will flow into the vagina through the diversion hole to flush, realizing periodic intermittent vaginal flushing and avoiding over-cleaning.
[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation
[0023] Please see Figure 1-4 This utility model is a vaginal irrigation device, including a delivery pipe 1 for delivering irrigation fluid, and irrigation pipes 2 and a storage tank 3 for storing irrigation fluid connected to both ends of the delivery pipe 1.
[0024] A miniature water pump 9 is installed at the end of the delivery pipe 1 away from the flushing pipe 2. The pumping end of the miniature water pump 9 is inserted into the flushing liquid inside the storage tank 3.
[0025] Specifically, when using the device, first insert the flushing tube 2 into the vagina, then turn on the micro water pump 9 to draw the flushing liquid from the storage tank 3, and then deliver the flushing liquid to the flushing tube 2 along the delivery tube 1 to flush the inside of the vagina. There is no need to manually squeeze the flushing liquid into the flushing tube 2, which saves manpower.
[0026] Specifically, the end of the flushing pipe 2 away from the delivery pipe 1 is sealed with an elastic diaphragm 7, and the diameter of the elastic diaphragm 7 when it is stretched and bulged is greater than the diameter of the flushing pipe 2.
[0027] Specifically, the elastic diaphragm 7 is located at the innermost end of the vagina. In the initial state, the elastic diaphragm 7 is in a naturally contracted state. Then, the irrigation tube 2 is inserted into the vagina. When irrigation fluid is delivered into the irrigation tube 2, the irrigation fluid will expand the elastic diaphragm 7 and press against the inner wall of the vagina to prevent the irrigation tube 2 from falling out of the vagina, thus making it easier to insert the irrigation tube 2 into the vagina.
[0028] Furthermore, a baffle 8 is fixed at one end of the delivery pipe 1 that connects to the flushing pipe 2 to prevent splashing of the used flushing fluid.
[0029] Specifically, the rinsing solution that flows out of the vaginal opening after rinsing carries bacteria. It is blocked and drained by a baffle to prevent the used rinsing solution from splashing onto medical staff and causing bacterial infection.
[0030] Furthermore, a mesh tube 4 is rotatably provided on the inner wall of the flushing pipe 2 along its circumference. An impeller 5 is fixed at one end of the mesh tube 4 near the conveying pipe 1, and the rotation axis of the impeller 5 coincides with the rotation axis of the mesh tube 4.
[0031] The flushing pipe has several diversion holes 6 evenly distributed in a circular array on its two sides. The diversion holes 6 are set on the rotation path of the mesh on the mesh pipe 4.
[0032] Specifically, as the rinsing fluid flows from the delivery pipe 1 into the rinsing pipe 2, it passes through the impeller 5 and drives the impeller 5 to rotate, which in turn drives the mesh pipe 4 to rotate. This causes the mesh holes on the mesh pipe 4 to alternately align with the diversion holes 6 on the rinsing pipe 2. When there is an overlap between the mesh holes and the diversion holes 6, the rinsing fluid will flow into the vagina through the diversion holes 6 to rinse, thus achieving periodic intermittent rinsing of the vagina and avoiding over-cleaning.
[0033] Furthermore, as the diversion orifice 6 gradually moves away from the inner wall of the flushing pipe 2, its inner diameter gradually decreases, and the degree of change in the inner diameter of different diversion orifices 6 is different.
[0034] The angle at which the diversion hole 6 narrows inward from the inner wall of the flushing pipe 2 toward the inner wall of the flushing pipe 2 is between 0° and 45°.
[0035] The inner diameter of the diversion hole 6 near the inner wall of the flushing pipe 2 is the same as the inner diameter of the mesh hole in the mesh pipe 4.
[0036] Specifically, the flushing tube 2 has multiple diversion holes 6 of different sizes on its sides. The inner diameter of the diversion holes 6 gradually decreases from near the inner wall of the flushing tube 2 to away from the inner wall of the flushing tube 2. That is, one end is the same as the inner diameter of the mesh, and the other end gradually contracts inward. Some contract inward by 10°, some by 20°, etc., and the contraction range is between 0° and 45°. The more inward it contracts, the greater the water flow velocity of the outlet hole of the diversion hole 6. As a result, the flushing force of the flushing liquid flowing out of the flushing tube 2 is also different. The water flow velocity is low and the force is low, so the flushing is gentle. The water flow velocity is high and the force is strong, so it can flush away stubborn bacteria and improve the efficiency of vaginal flushing.
