Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a vaginal dilator and irrigator. Background Technology

[0002] Vaginal dilation is used to prevent and alleviate vaginal mucosal fibrosis, scar contracture, stenosis, and adhesion closure caused by radiotherapy. It maintains the normal vaginal cavity shape, length, and elasticity, reduces vaginal secretion accumulation and secondary infections, and facilitates regular gynecological follow-ups, sampling, and necessary intracavitary diagnostic and therapeutic procedures after radiotherapy. It also relieves symptoms such as local pain and discomfort during intercourse, effectively improving patients' long-term quality of life and reproductive health. The vaginal dilator and irrigator combines flexible and controllable dilation, precise constant temperature and pressure irrigation, and intelligent monitoring. It is suitable for vaginal irrigation in preoperative gynecological cleaning, postoperative care, post-radiotherapy vaginal care, adjuvant treatment of infectious diseases, and daily hygiene maintenance. To meet a wide range of clinical needs, this device can effectively remove vaginal secretions, necrotic tissue, pathogenic microorganisms, and residual drugs, while effectively preventing vaginal stenosis and adhesions after radiotherapy. It achieves safer, more comfortable, precise, and efficient vaginal dilation and cleaning care, and can be expanded to include functions such as medication application. It creates favorable conditions for examination, treatment, and wound healing. In order to achieve safe and gentle dilation of the vaginal wall, fully expose the folds of the inner wall, ensure that the rinsing solution can fully cover the vaginal wall and avoid incomplete rinsing, and at the same time ensure gas sealing during dilation to prevent leakage, thereby improving the safety and effectiveness of rinsing, a vaginal dilator and irrigator is needed.

[0003] Currently, the most common clinical methods of vaginal irrigation rely on traditional irrigation devices, which typically consist of a simple catheter or nozzle with a water outlet. During the procedure, the catheter is inserted into the vagina, and irrigation fluid is injected through an external pressure source. The problem with this method is that the vaginal wall is not a smooth lumen; its surface has numerous folds. Simple water spraying makes it difficult for the irrigation fluid to fully and evenly reach and clean the deep folds and fornix, easily creating irrigation dead zones, resulting in incomplete cleaning and affecting the treatment effect or the quality of preoperative preparation. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a vaginal dilator and irrigator that solves the problem that simple water spraying is insufficient to clean deep folds and fornix areas, easily creating blind spots and resulting in incomplete cleaning.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a vaginal dilator and irrigator, comprising a handle, a connecting nozzle slidably connected to the inner wall of the handle, a connecting groove formed on the outer wall of the connecting nozzle, a water channel sealing ring fitted on the outer wall of the connecting nozzle, a water spray pipe fixedly connected to the top of the connecting nozzle, an air bladder fitted on the outer wall of the water spray pipe, a large-end sealing boss at the bottom of the air bladder, a small-end sealing boss at the top of the air bladder, the outer wall of the large-end sealing boss being tightly fitted to the bottom of the water spray pipe, the outer wall of the small-end sealing boss being tightly fitted to the top of the water spray pipe, a locking device slidably connected inside the handle, a locking spring being provided inside the locking device, one end of the locking spring being fixedly connected to the inner wall of the handle, and the other end being fixedly connected to the end of the locking device, the inner wall of the locking device engaging with the inner wall of the connecting groove, water holes formed inside both the handle and the connecting nozzle, and an air intake assembly being provided at the end of the handle, the air intake assembly being slidably connected to the bottom of the water spray pipe.

[0006] Preferably, the air intake assembly includes an air nozzle, the outer wall of which is fixedly disposed through the end of the handle, the outer wall of which is slidably connected to the bottom of the water spray pipe, and an air passage sealing ring is fitted on the outer wall of the air nozzle.

[0007] Preferably, the top end of the water spray pipe is threaded with a nozzle, and the inside of the nozzle is slidably connected with a lower hammer and an upper hammer, the outer wall of the lower hammer is in contact with the water outlet of the water spray pipe, and the outer wall of the upper hammer is in contact with the water outlet of the nozzle.

[0008] Preferably, a vibration spring is provided inside the nozzle.

[0009] Preferably, one end of the vibration spring is fixedly connected to the outer wall of the lower hammer, and the other end is fixedly connected to the outer wall of the upper hammer.

[0010] Preferably, an air pump and a water pump are fixedly connected to the inner wall of the handle, and an air inlet pipe is fixedly provided at both the input and output ends of the air pump.

[0011] Preferably, the outer wall of the air intake pipe is fixedly connected to the inner wall of the handle and the air nozzle, respectively.

[0012] Preferably, both the input and output ends of the water pump are fixedly provided with water inlet pipes, and the outer wall of the water inlet pipes is fixedly connected to the inner wall of the handle and the water hole, respectively.

[0013] Preferably, a pull rope is fixedly connected to the outer wall of the airbag, and a control button is installed on the outer wall of the handle.

[0014] Preferably, both the air pump and the water pump are electrically connected to the control buttons.

[0015] Working Principle: When needed, first insert the spray hose and airbag into the end of the handle. At this time, the connector nozzle forms a tight fit with the inner wall of the handle under the action of the water channel sealing ring. The locking device is locked into the connecting groove under the elastic force of the locking spring, realizing a quick locking connection between the spray hose and the handle. Then, insert the spray hose and airbag into the vagina together, and start the air pump by pressing the inflation button on the control panel. The air pump delivers air to the air nozzle through the air inlet pipe. The air enters the airbag through the air passage at the bottom of the spray hose. As the air is continuously inflated, the airbag gradually expands from its initial contracted state. Its outer wall gently contacts the vaginal wall and slowly expands. During this process, the large sealing boss at the bottom of the airbag fits tightly with the bottom of the spray hose, and the small sealing boss at the top fits tightly with the top of the spray hose and the outer wall of the nozzle. With the help of the air passage sealing ring, gas leakage is effectively prevented, ensuring that the airbag expands stably to fully expose the folds of the vaginal wall. After the airbag has expanded to the required size, press... The flushing button in the control panel starts the water pump, which pumps the flushing solution into the spray pipe through the inlet pipe and water holes. The high-pressure water flow enters the spray pipe through the water holes in the handle and connector, first pushing open the lower hammer and then reaching the upper hammer, increasing the water pressure in the cavity. This pushes the lower hammer to seal the spray pipe outlet, and the upper hammer to open the nozzle, thus spraying water. After some water is sprayed out, the water pressure drops, and the lower hammer is pushed open again by the high-pressure water flow, entering the next cycle, thereby achieving phased atomization of the water flow. At the same time, when the water pressure impacts the lower hammer, it compresses the vibration spring and pushes the upper hammer to move synchronously, causing the upper hammer to detach from the nozzle outlet and release water. When the water pressure decreases, the vibration spring resets, causing the lower and upper hammers to rebound. The upper hammer re-fits the nozzle outlet, blocking the water flow, creating a pulsed water effect that enhances the flushing force and cleaning effect. The fitting structure between the lower hammer and the spray pipe outlet also prevents sewage backflow, ensuring hygiene and safety during the flushing process. After use, pull the spray hose and airbag out of the vagina together, press the locking device to compress the locking spring, and release the locking device from the connecting groove. Then the spray hose and airbag can be quickly removed from the handle, making it easy to thoroughly clean, disinfect or replace the airbag and spray hose to avoid cross-infection.

[0016] This invention provides a vaginal dilator and irrigator. It has the following beneficial effects: 1. This invention combines an expanding airbag with a water spray pipe. The airbag gradually inflates to gently expand the vaginal wall, exposing the folds of the vaginal wall. The large-end sealing boss and the small-end sealing boss are tightly fitted to both ends of the water spray pipe to ensure the sealing performance between the airbag and the water spray pipe, preventing gas leakage. This achieves the effect of rinsing the folds of the vaginal wall and avoiding incomplete rinsing.

[0017] 2. This invention achieves quick assembly and disassembly of the water spray pipe and handle through the locking mechanism of the locking device and the connecting groove. When it is necessary to replace or clean the airbag and water spray pipe, the locking device can be disengaged from the connecting groove by pressing the locking device to compress the locking spring, thus completing the disassembly operation. This effectively avoids bacterial growth and cross-infection caused by the inability to thoroughly clean the parts, greatly improving the convenience and hygiene safety of the product.

[0018] 3. The present invention uses a linkage structure of lower hammer, upper hammer and vibration spring. When the water flow impacts the lower hammer, it compresses the vibration spring to generate reciprocating vibration, forming a staged atomized water output. This allows the water flow to be sprayed out at a larger angle, which can obtain a larger flushing area and enhance the flushing force to the deep folds of the vaginal wall.

[0019] 4. This invention integrates an air pump, a water pump, and control buttons to achieve integrated intelligent control of airbag inflation and irrigation fluid delivery. Medical staff or users can easily switch working states by pressing the control buttons, achieving gentle airbag expansion and atomized irrigation fluid spraying to evenly cover the target area. This simplifies the operation process, achieves integrated intelligent control, avoids the tedium of manual adjustment, improves operational accuracy and safety, and is suitable for rapid clinical operation and home self-care scenarios.

[0020] 5. By setting a pull cord, after the airbag is inflated and expanded, the airbag can be gently pulled to adjust its position smoothly. This also prevents the airbag from falling off when it is pulled out, which facilitates the adjustment of the airbag's position and assists in its removal. This ensures the safety and convenience of the operation process, improves the patient's comfort, and ensures the smooth progress of vaginal dilation and irrigation. Attached Figure Description

An air bladder 12 is fitted onto the outer wall of the water spray pipe 5. A large-end sealing boss 13 is provided at the bottom end of the air bladder 12, and a small-end sealing boss 14 is provided at the top end of the air bladder 12. The outer wall of the large-end sealing boss 13 is flush with the bottom end of the water spray pipe 5. The outer wall of the small end sealing boss 14 is tightly attached to the top of the water spray pipe 5. The handle 1 is slidably connected to the locking device 6. The locking device 6 is equipped with a locking spring 7. One end of the locking spring 7 is fixedly connected to the inner wall of the handle 1, and the other end is fixedly connected to the end of the locking device 6. The inner wall of the locking device 6 is engaged with the inner wall of the connecting groove 3. Water holes 15 are opened inside the handle 1 and the connecting nozzle 2. An air intake component is provided at the end of the handle 1. The air intake component is slidably connected to the bottom of the water spray pipe 5. Specifically, the handle 1 facilitates easy operation of the entire device, allowing medical staff to perform vaginal dilation and irrigation with one hand, thus improving usability. The sliding connection between the connector 2 and the handle 1 enables flexible installation of the spray pipe 5, quickly connecting it to the handle 1 and ensuring overall structural stability. The locking mechanism between the connecting groove 3 and the locking device 6 positions and fixes the connector 2, preventing the spray pipe 5 from loosening during use and ensuring operational safety. The sealing ring 4 provides waterproofing between the connector 2 and the handle 1, preventing water leakage and ensuring stable irrigation pressure. The spray pipe 5 delivers water precisely, ensuring the irrigation water reaches the vaginal wall for thorough cleaning. The inflation of the airbag 12 expands the vaginal wall, fully exposing the folds of the vaginal wall and facilitating the contact and cleaning of the rinsing solution. The sealing engagement of the large-end sealing boss 13 and the small-end sealing boss 14 seals and fixes the airbag 12, preventing air leakage and ensuring stable dilation. The locking device 6 and the locking spring 7 work together to quickly lock and unlock the connecting nozzle 2, facilitating the disassembly and cleaning of the spray pipe 5 and the airbag 12 and preventing cross-infection. The water hole 15 circulates the rinsing solution, continuously providing water for rinsing and ensuring a clean effect. Through the cooperation of these components, convenient disassembly and operation are achieved, cross-infection is effectively avoided, and the thoroughness of rinsing is improved, making it suitable for clinical use scenarios of vaginal dilation and rinsing.

[0025] Please see the appendix Figure 3 and attached Figure 4 The air intake assembly includes an air nozzle 16. The outer wall of the air nozzle 16 is fixedly disposed through the end of the handle 1. The outer wall of the air nozzle 16 is slidably connected to the bottom of the water spray pipe 5. An air passage sealing ring 17 is fitted on the outer wall of the air nozzle 16. Specifically, the inflation action of the air nozzle 16 causes the airbag 12 to expand, achieving vaginal dilation and meeting clinical operation requirements; the sealing action of the airway sealing ring 17 causes the air nozzle 16 and the water spray pipe 5 to seal, preventing air leakage during inflation and ensuring stable expansion of the airbag 12. Both the waterway sealing ring 4 and the airway sealing ring 17 are made of medical-grade silicone material to ensure safe use.

[0026] Please see the appendix Figure 1 - Appendix Figure 6The top end of the water spray pipe 5 is threaded with a nozzle 11. Inside the nozzle 11, a lower hammer 8 and an upper hammer 10 are slidably connected. The outer wall of the lower hammer 8 is in contact with the outlet of the water spray pipe 5, and the outer wall of the upper hammer 10 is in contact with the outlet of the nozzle 11. A vibration spring 9 is installed inside the nozzle 11. One end of the vibration spring 9 is fixedly connected to the outer wall of the lower hammer 8, and the other end is fixedly connected to the outer wall of the upper hammer 10. Specifically, the high-pressure water flow impacts the lower hammer 8, causing it to detach from the outlet of the spray pipe 5, allowing water to smoothly enter the nozzle 11. The lower hammer 8, by adhering to the outlet of the spray pipe 5, seals the water path, preventing water leakage and backflow of wastewater, ensuring hygienic and safe rinsing. The expansion and contraction of the vibration spring 9 causes the lower hammer 8 and upper hammer 10 to reciprocate, coordinating with water pressure changes to achieve water circulation. The upper hammer 10, by adhering to and detaching from the outlet of the nozzle 11, controls the water flow, regulating the spray rhythm and creating a phased atomized water effect. This process is achieved through the nozzle 11... The various components house the entire pulse structure, ensuring stable operation and achieving atomization of the water flow to enhance the rinsing coverage. High-pressure water propels the upper hammer 10, opening the nozzle 11 and allowing the atomized water to spray out smoothly, thus increasing rinsing power. The vibration spring 9 resets the lower hammer 8 and upper hammer 10, maintaining circulation and ensuring a continuous and stable pulse water flow. The coordinated action of the lower hammer 8 and upper hammer 10 enables phased water spraying, improving rinsing effectiveness while avoiding waste caused by continuous water flow.

[0027] Please see the appendix Figure 3 - Appendix Figure 5 An air pump 18 and a water pump 21 are fixedly connected to the inner wall of the handle 1, and an air inlet pipe 19 is fixedly provided at both the input and output ends of the air pump 18. The outer wall of the air inlet pipe 19 is fixedly connected to the inner wall of the handle 1 and the air nozzle 16, respectively. A water inlet pipe 22 is fixedly provided at both the input and output ends of the water pump 21, and the outer wall of the water inlet pipe 22 is fixedly connected to the inner wall of the handle 1 and the water hole 15, respectively. Specifically, the handle 1 carries the air pump 18 and water pump 21, which helps to stably install the core components, achieving a compact overall structure and easy handheld operation. The air pump 18 delivers gas, ensuring stable gas flow and providing sufficient air supply to the airbag 12 for smooth inflation. The air inlet pipe 19 conducts gas, ensuring precise gas delivery and preventing gas leakage, thus ensuring efficient gas delivery to the air nozzle 16. The water pump 21 delivers liquid, ensuring stable flow of the flushing fluid, providing sufficient power for flushing operations and ensuring flushing effectiveness. The water inlet pipe 22 conducts liquid, ensuring precise delivery of the flushing fluid, preventing leakage and ensuring smooth delivery of the flushing fluid to the water hole 15. The input end of the water pump 21 can be connected to an extension pipe, which can be connected to an infusion bag or flushing fluid container to achieve continuous fluid supply and adapt to different volumes and types of flushing fluid. Both the air pump 18 and water pump 21 use miniature silent pump bodies, resulting in low noise during operation, reducing disturbance to patients and improving the user experience.

[0028] Please see the appendix Figure 1 - Appendix Figure 4 A pull rope 20 is fixedly connected to the outer wall of the airbag 12, and a control button 23 is installed on the outer wall of the handle 1; the air pump 18 and the water pump 21 are both electrically connected to the control button 23. Specifically, control buttons 23 include an inflation button, a flushing button, and a power switch. Air pump 18 is electrically connected to the inflation button, and water pump 21 is electrically connected to the flushing button. Pressing the inflation button on control buttons 23 starts and stops air pump 18, ensuring stable gas delivery to the air nozzle 16. This causes the airbag 12 to gradually inflate from its initial contracted state, resulting in gentle contact and slow expansion of the outer wall of the airbag 12 against the vaginal wall, fully exposing the folds of the vaginal wall. Pressing the flushing button on control buttons 23 starts and stops water pump 21, ensuring the flushing fluid is stably pumped into the spray pipe 5 through the inlet pipe 22 and water hole 15. The power switch on control buttons 23 starts and stops both air pump 18 and water pump 21. The device achieves flexible control of its operating status and ease of use. The three buttons on control button 23 have clearly defined functions, namely starting air pump 18, starting water pump 21, and starting / stopping the entire device. This results in simple and easy-to-understand operation, adaptability to different usage steps, and improved user experience. Since air pump 18 and water pump 21 are electrically connected to control button 23, they ensure stable transmission of control signals, achieving synchronization between button operation and device operation with sensitive response. The pull rope 20 fixed to the outer wall of airbag 12 enables the airbag 12 to quickly retract and reset after use, facilitating the removal of airbag 12 and improving ease of use. It also prevents airbag 12 from falling off when pulled out. The pull rope 20 is made of medical-grade flexible material.
