Description

Technical Field

[0001] This invention relates to the field of medical assistive device technology, and in particular to a sterilization device and method for female assisted reproductive care. Background Technology

[0002] In the process of implementing assisted reproductive technologies in women, thorough and safe cleaning and disinfection of the reproductive tract, especially the vagina, is a crucial preliminary step. This procedure aims to reduce the risk of infection and provide a clean physiological environment for subsequent procedures such as embryo transfer. Currently, the commonly used clinical methods for disinfection often involve medical staff manually wiping with cotton swabs dipped in disinfectant, or flushing with a syringe connected to a catheter. However, these existing methods have some shortcomings:

[0003] 1. Patients usually need to maintain a specific position during disinfection. However, due to individual differences in body shape, nursing chairs or beds are difficult to fully conform to the patient's body curves, which can cause the rinsing solution to easily flow out along the gaps between the body and the chair. This not only contaminates the operating environment but may also soak the patient's clothes, causing discomfort.

[0004] 2. Existing nursing disinfection devices either have fixed nozzles (which create cleaning dead zones) or motor-driven telescopic rotation. Motors are prone to electric leakage in humid environments, and the complex transmission mechanism is extremely difficult to thoroughly disinfect and clean, easily accumulating dirt and grime. However, in humid environments, there is a risk of electric leakage, posing a safety hazard to patients and medical staff.

[0005] 3. Once existing medical waste fluid suction devices adhere to human tissue, doctors usually need to manually pull them out by touch or step on a switch to turn off the negative pressure device. This delay of a few seconds is enough to cause congestion, purpura, or even tearing and bleeding of the fragile reproductive tract mucosa.

[0006] Therefore, there is a need for a nursing sterilizer that can better adapt to the patient's body shape, achieve safe and thorough cleaning, and avoid mucosal damage. Summary of the Invention

[0007] This invention addresses the serious safety hazards of electric leakage from electric flushing nozzles in humid environments during pre-operative care and rinsing in women undergoing assisted reproductive technology; the tendency of negative pressure suction devices to attract and damage the fragile reproductive tract mucosa, causing congestion, purpura, or even tearing and bleeding; and the tendency of rinsing waste liquid to leak along the gaps between the patient's body and the seat, contaminating the operating environment and the patient's clothing. Existing devices cannot simultaneously solve the clinical pain points of safe, non-electric flushing, non-damaging suction, and leak-proof sealing. Therefore, this invention proposes a sterilizer and method for women undergoing assisted reproductive technology care.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A sterilization device for female assisted reproductive care, comprising:

[0010] A nursing chair, wherein the nursing chair is provided with a cushion mechanism, the cushion mechanism including an inner ring airbag fixed on the nursing chair and an annular storage tray surrounding the inner ring airbag;

[0011] A cleaning cylinder is disposed on the nursing seat. The cleaning cylinder contains a rinsing mechanism, which includes a sliding ring, a turntable, and a fixed ring. The sliding ring is slidably and sealingly connected to the inner wall of the cleaning cylinder. The turntable is rotatably connected to one end of the sliding ring. The fixed ring is fixed inside the cleaning cylinder. The sliding ring is provided with a sealing plate I for closing the fixed ring.

[0012] A suction cylinder is provided on the nursing seat. The suction cylinder has a suction structure inside, and the suction structure includes a suction tube that communicates with the suction cylinder.

[0013] In one possible design, the nursing chair includes a base, a backrest, and two armrests. The backrest is fixed to the top of the base and located between the two armrests. A spherical seat and a spherical pad for supporting the patient are fixed to one side of the backrest. The inner airbag and the annular storage tray are both fixed to the top of the spherical seat.

[0014] In one possible design, the flushing mechanism further includes a cross-shaped mounting bracket fixed within the sliding ring, a rotating shaft that rotates through the cross-shaped mounting bracket, and a turbine fixed to one end of the rotating shaft. The other end of the rotating shaft is fixedly connected to the turntable, and the outer wall and end face of the turntable are provided with multiple spray holes.

[0015] After the external flushing fluid enters the cleaning cylinder, the hydraulic pressure pushes the sealing plate I and drives the sliding ring and the turntable to move out of the cleaning cylinder. At the same time, when the flushing fluid flows through the turbine, it drives the turbine to rotate the turntable, so that the flushing fluid is sprayed out from the rotating nozzle to flush the vaginal wall at multiple angles.

[0016] In one possible design, the inner wall of the cleaning cylinder is provided with an annular groove, and a retaining ring is slidably connected in the annular groove and fixedly sleeved on the outer wall of the sliding ring. A spring I is sleeved on the outer wall of the sliding ring, and the two ends of the spring I abut against one side of the inner wall of the annular groove and one side of the retaining ring, respectively, to drive the sliding ring to reset when the flushing liquid stops, so that the sealing plate I re-closes the fixed ring.

[0017] In one possible design, an inner tube is fixed inside the sliding ring, and a through hole I is provided inside the inner tube to connect the fixed ring and the turbine. The diameter of the through hole I gradually decreases along the flow direction of the flushing fluid to form an acceleration channel. A spiral guide plate for generating spiral flow of the flushing fluid is fixed inside the through hole I. The flushing fluid, after being accelerated and spirally guided, acts together on the turbine to drive the turbine to rotate.

[0018] In one possible design, the suction structure further includes a fixed plate fixed to one end of the suction cylinder and a sealing plate II fixed to one end of the suction tube. One end of the suction tube is fixedly inserted through the fixed plate, and the sealing plate II is provided with multiple suction holes. The outer wall of the suction tube is provided with a pressure relief hole, and a protruding tube is fixed inside the suction tube. An annular groove is formed between the protruding tube and the inner wall of the suction tube. A piston plate is slidably connected in the annular groove. A sealing ring for sealing the pressure relief hole is fixed on one side of the piston plate, and the other side of the piston plate is connected to the inner wall of the annular groove through a spring II. The side wall of the annular groove is provided with a through hole II communicating with the inside of the suction tube.

[0019] When the suction hole adsorbs the mucous membrane, causing a sharp increase in negative pressure, the increased negative pressure acts on the piston plate through the through hole II, causing it to overcome the elastic force of the spring II, drive the sealing ring to move and open the pressure relief hole to break the vacuum. After the negative pressure returns to normal, the spring II drives the sealing ring to re-close the pressure relief hole.

[0020] In one possible design, the cushion mechanism further includes an outer ring airbag fixed to the top of the annular storage tray, and the bottom of the inner ring airbag is connected to the bottom of the outer ring airbag through multiple connecting pipes.

[0021] When the patient sits down, the inner airbag is squeezed, causing the gas inside to flow into the outer airbag through the connecting tube. The outer airbag inflates and conforms to the curves of the patient's groin and buttocks, forming a flexible, sealed barrier that fits the patient's body shape.

[0022] In one possible design, the outer wall of the spherical base is provided with a guide channel, the top of which extends to the annular gap between the inner ring airbag and the annular storage tray, and a collection tray located below the bottom of the guide channel is fixed to the top of the base for collecting waste liquid guided by the guide channel.

[0023] In one possible design, a camera is fixed to the outer wall of the suction tube via a mounting plate. The camera is used to capture images of the inside of the vagina when the suction tube is inserted into the patient's vagina to help position the end of the suction tube to the point of waste accumulation.

[0024] Through the above-mentioned technical solution, this invention not only solves the problems of easy leakage of electricity, easy damage to the mucosa, and easy leakage of waste liquid in the existing technology, but also achieves the technical effect of completing the entire process of adaptive sealing, safe flushing, and non-damaging aspiration without any additional power or electrical components, using the patient's own gravity and flushing fluid pressure as the only power source. At the same time, it is suitable for patients of different body types and completely eliminates the three major safety risks of leakage of electricity, mucosal damage, and waste liquid leakage.

[0025] A method for using a sterilizing device for female assisted reproductive care includes the following steps:

[0026] The patient sits on a spherical seat with their back against the backrest, supported by a spherical cushion, with their feet resting on the footrests at the top of the armrests, exposing their perineum.

[0027] The buttocks compress the inner air bladder, and the gas flows into the outer air bladder through the connecting tube, causing it to inflate. It fits the root of the thigh and forms a seal with the annular storage tray. Waste liquid collects in the annular gap and flows into the collection tray through the guide channel.

[0028] Insert the cleaning tube into the vagina. The rear end is connected to the peristaltic pump through a soft tube. After starting, the flushing fluid pressure overcomes the spring I and pushes open the sealing plate I, causing the sliding ring, inner tube, cross mounting bracket and turntable to move forward and extend. At the same time, the retaining ring slides in the annular groove to compress the spring I. The flushing fluid flows through the fixed ring and enters the inner tube. It is accelerated through the through hole I and guided to rotate by the spiral guide plate. The impact turbine drives the rotating shaft to rotate the turntable. The spray nozzle sprays the flushing fluid to flush from multiple angles.

[0029] After the pump is turned off, spring I returns to its original position, pushing the retaining ring to slide in the opposite direction, which in turn drives the sliding ring and other components to return to their original positions. The sealing plate I then re-closes, and the turntable retracts. After the rinsing is completed, the peristaltic pump is turned off. After the turntable automatically returns to its original position, the cleaning tube is pulled out of the patient's vagina. At this time, the residual rinsing fluid and sloughed tissue debris in the vagina gather at the posterior fornix of the vagina.

[0030] Holding the suction tube, with the assistance of a camera, insert the end of the suction tube into the vagina and position it in the posterior fornix. Activate the negative pressure device. Waste fluid is drawn in through the suction holes on the sealing plate II. If the suction holes adsorb the mucosa, the negative pressure increases and is conducted through the through hole II to the piston plate in the annular groove. This overcomes the elasticity of spring II, causing the piston plate to retract and exposing the pressure relief hole to the sealing ring. Outside air enters, the negative pressure disappears, and the mucosa detaches. After the mucosa detaches, the negative pressure returns, spring II pushes the piston plate back to its original position, the sealing ring closes the pressure relief hole, and suction continues.

[0031] Beneficial effects: In this invention, the cushion mechanism uses the patient's own weight as a power source. Through the synergistic effect of the inner ring airbag, the connecting tube and the outer ring airbag, the outer ring airbag physically expands to form a flexible seal that conforms to the individualized body curve of the patient. This effectively prevents the flushing fluid from flowing out along the gap between the body and the seat, keeping the operating environment dry and clean. The design of the guide channel and the collection tray guides and collects the accumulated waste fluid in an orderly manner, avoiding secondary pollution.

[0032] In this invention, the rinsing mechanism adopts a purely mechanical structure, relying entirely on the flow pressure of the rinsing fluid to drive the extension, rotation, and reset of the turntable. During the rotation, the turntable rinses the vaginal wall from multiple angles through the spray holes on it, which can deeply clean the folds and fornix, resulting in a more thorough cleaning effect. The entire driving process requires no electricity, avoiding the risk of electric leakage that may be caused by using electric instruments in a humid environment, and significantly improving the safety of operation.

[0033] In this invention, the suction structure integrates an automatic safety pressure relief function. When the suction port at the end of the suction tube accidentally adsorbs the mucosa, causing an abnormal increase in negative pressure, the pressure relief port can be automatically opened to quickly break the vacuum environment and allow the mucosa to detach without damage. After the negative pressure returns to normal, the pressure relief port can be automatically closed to ensure the continuity of suction work, reduce the risk of damage to the reproductive tract mucosa caused by negative pressure suction, and demonstrate the protection of the patient's physiological structure.

[0034] This invention integrates a female assisted reproductive technology sterilizer that combines leak prevention, multi-angle hydrodynamic flushing, and negative pressure safety protection. Through its mechanical structure design, it utilizes gravity to form a dynamic seal, uses water flow to achieve non-electric multi-directional cleaning, and utilizes pressure difference changes to achieve automatic mucosal protection during the suction process. This sterilizer can adapt to patients of different body types, achieving vaginal cleaning and disinfection while ensuring operational safety and avoiding the risks of electric shock and mucosal damage. This provides strong support for the smooth implementation of assisted reproductive technology. Attached Figure Description

[0047] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0048] In one embodiment: Refer to Figure 1 and Figure 2 A sterilization device for female assisted reproductive care, relating to the field of medical auxiliary device technology, mainly includes a nursing seat, as well as a cushion mechanism, a rinsing mechanism and a suction structure disposed on the nursing seat.

[0049] Reference Figure 1 and Figure 2 The nursing chair forms the supporting foundation of the entire device. It consists of a base 1, a backrest 2, and two armrests 4. The base 1, as the part in contact with the ground, provides stable support. The two armrests 4 are symmetrically fixed to the top of the base 1. They not only provide support for the patient's arms but also provide a location for the placement of some subsequent components. The backrest 2 is also fixed to the top of the base 1 and is located between the two armrests 4. Its main function is to provide support for the patient. To improve the patient's comfort when sitting or lying down, a spherical seat 7 and a spherical pad 3 are fixed to one side of the backrest 2, that is, the side facing the patient. The spherical seat 7 is located under the patient's buttocks. Its curved design is designed to better fit the curve of the buttocks and bear the main weight of the patient when sitting. The spherical pad 3 is located on the backrest 2, corresponding to the patient's lower back. Its raised spherical structure can provide an effective support point for the patient's back and help the patient maintain stability during the disinfection process.

[0050] Reference Figures 2-4 The seat cushion mechanism is a key component in solving the problem of external leakage of the flushing fluid. This mechanism is installed on the spherical seat 7 of the nursing seat and specifically includes an inner ring airbag 8, an annular storage tray 9, and an outer ring airbag 10. The inner ring airbag 8 and the annular storage tray 9 are both fixed to the top of the spherical seat 7, and the inner ring airbag 8 is located inside the annular storage tray 9, forming an inner and outer ring structure. The outer ring airbag 10 is fixed to the top of the annular storage tray 9. The bottom of the inner ring airbag 8 and the bottom of the outer ring airbag 10 are fixedly connected by multiple connecting pipes 11. These connecting pipes 11 allow the inner cavity of the outer ring airbag 10 to communicate with the inner cavity of the inner ring airbag 8, and gas can flow freely between the two.

[0051] Specifically, when the patient sits on the spherical seat 7, their buttocks are directly pressed against the inner airbag 8. The patient's own weight will compress the inner airbag 8, causing the gas inside to be compressed. The compressed gas will be squeezed into the outer airbag 10 through the connecting tube 11. As the gas enters, the originally relatively loose outer airbag 10 will physically expand due to the increased internal air pressure, becoming full and expanding outward. These expanded outer airbags 10 are located precisely in the gap between the patient's groin and buttocks and the annular storage tray 9. They can closely fit the different curves of the groin and buttocks of different patients, forming an effective personalized physical sealing barrier. In this way, when performing vaginal irrigation, the irrigation fluid flowing out of the vaginal opening will be blocked by this sealing barrier formed by the connecting tube 11, and will not flow out from the gap between the body and the seat, thus avoiding the irrigation fluid from contaminating the operating environment and the patient's clothing. The waste fluid will temporarily accumulate in the annular gap formed by the inner airbag 8, the annular storage tray 9, and the expanded outer airbag 10.

[0052] Reference Figure 1 and Figure 2 To handle these accumulated waste liquids, a guide channel 43 is provided on the outer wall of the spherical seat 7. The top opening of the guide channel 43 is directly opposite the bottom of the annular gap, which is used to receive the waste liquid in the annular gap and guide it downward. The bottom end of the guide channel 43 is located above the collection tray 5 fixed on the top of the base 1, so that the guided waste liquid can fall accurately into the collection tray 5, achieve centralized collection, and keep the operating area clean.

[0053] Reference Figures 5-7 The rinsing mechanism is the core component for achieving multi-angle, thorough cleaning of the vaginal interior. It is housed within a cleaning cylinder 13, one end of which is connected to an external peristaltic pump via a flexible tube 14. The peristaltic pump delivers rinsing fluid into the cleaning cylinder 13. The internal structure of the cleaning cylinder 13 is quite precise. A sliding ring 16 is slidably mounted on the inner wall of the cleaning cylinder 13 via a slide rail, achieving a sealed sliding motion between the sliding ring 16 and the inner wall of the cleaning cylinder 13. Inside the cleaning cylinder 13, a fixing ring 15 is fixedly installed. The sliding ring 16 is located on the side furthest from the connection end of the flexible tube 14. The end of the sliding ring 16 away from the fixed ring 15 is rotatably connected to a turntable 23 via a bearing or other means. Multiple small spray holes 27 are provided on the outer circumferential surface and the end face facing the patient of the turntable 23. Inside the sliding ring 16, a sealing plate I 20 is fixedly connected via a vertical rod. The sealing plate I 20 is located at the end of the sliding ring 16 closer to the fixed ring 15. In its initial state, under the pushing force of the spring I 19, the end face of the sealing plate I 20 will tightly press against the central hole of the fixed ring 15, thereby sealing the ring and preventing foreign objects from entering the cleaning cylinder 13 when rinsing is not performed.

[0054] Reference Figures 5-7In order to control the movement of the sliding ring 16, an annular groove 17 is provided on the inner wall of the cleaning cylinder 13. A retaining ring 18 is fixedly sleeved on the outer wall of the sliding ring 16, and the retaining ring 18 is located exactly in the annular groove 17 and can slide in the annular groove 17. A spring I 19 is also provided in the annular groove 17. The spring I 19 is sleeved on the outside of the sliding ring 16. One end of the spring I 19 abuts against the side wall of the annular groove 17, and the other end abuts against the side of the retaining ring 18. The spring I 19 always applies a pushing force to the retaining ring 18, pushing the retaining ring 18 to drive the entire sliding ring 16 to move away from the turntable 23, that is, so that the closing plate I 20 can maintain the closed state of the fixed ring 15.

[0055] Reference Figure 6 and Figure 7 Inside the sliding ring 16, there is a cross mounting bracket 24. A rotating shaft 25 is rotatably inserted through the center of the cross mounting bracket 24. At least one waterproof bearing (not shown in the figure) is embedded in the center hole of the cross mounting bracket 24. The rotating shaft 25 is rotatably connected to the cross mounting bracket 24 through the waterproof bearing. It can effectively withstand the radial and axial loads generated when the turbine 26 drives the turntable 23 to rotate, ensuring the smooth rotation of the turntable 23 and the service life of the device. One end of the rotating shaft 25, that is, the end away from the sealing plate I 20, is fixedly connected to the turntable 23. Therefore, the rotation of the rotating shaft 25 will drive the turntable 23 to rotate synchronously. The other end of the rotating shaft 25, that is, the end close to the sealing plate I 20, is fixedly installed with a turbine 26.

[0056] Specifically, medical personnel gently insert the front end of the cleaning tube 13, i.e., the end with the turntable 23, into the patient's vagina. Then, they activate an external peristaltic pump, and the flushing fluid is forced into the cleaning tube 13 through the tubing 14. The flushing fluid first reaches the fixing ring 15. Since the fixing ring 15 is initially sealed by the sealing plate I 20, the pressure of the flushing fluid gradually increases. When the pressure rises sufficiently to overcome the elasticity of the spring I 19, the flushing fluid pushes the sealing plate I 20, causing it to disengage from the fixing ring 15. The movement of the sealing plate I 20 then moves the entire sliding ring 1... 6. The inner tube 21, rotating shaft 25, and turntable 23 move together toward the inside of the vagina. At this time, the turntable 23 extends from the port of the cleaning tube 13 and enters the vaginal space. Simultaneously, the sealing plate I 20 releases the seal on the fixing ring 15, allowing the flushing fluid to pass through the fixing ring 15. As the sliding ring 16 moves, the retaining ring 18 fixed to it slides within the annular groove 17 and compresses the spring I 19. The flushing fluid continues to flow forward and enters the through hole I 22 of the inner tube 21. Due to the tapered structure of the through hole I 22 and the internal spiral guide plate 28, the flushing fluid is... The water is accelerated and forms a spiral flow. This water flow, carrying momentum and rotational characteristics, then impacts the turbine 26. The impact force of the water flow drives the turbine 26 to rotate. The rotation of the turbine 26 is transmitted to the rotating disk 23 through the rotating shaft 25, causing the rotating disk 23 to rotate slowly inside the vagina. At the same time, the flushing fluid is sprayed out from various nozzles 27 on the surface of the rotating disk 23. As the rotating disk 23 continues to rotate, the spray direction of the nozzles 27 on it also changes continuously, thereby enabling multi-angle and thorough flushing of the vaginal wall in all directions, including the folds and deep fornixes. The rinsing process relies entirely on the pressure of the water flow to drive the mechanical movement, eliminating the need for any electrical components such as motors. This fundamentally eliminates the potential safety hazard of electric leakage that may arise from using electrical appliances in humid environments. After rinsing, the peristaltic pump stops working, and the pressure of the rinsing fluid disappears. At this time, the compressed spring I19 begins to release energy, pushing the retaining ring 18, which in turn drives the sliding ring 16 and the sealing plate I20 to move in the opposite direction and reset. The sealing plate I20 then re-closes the fixing ring 15, and the turntable 23 is also retracted into the cleaning cylinder 13, ready for the next use.

[0057] Reference Figures 8-10The suction structure is used to remove waste fluid from the vagina after rinsing. Its design is specifically focused on preventing damage to the delicate mucosa. This structure is housed within a suction cylinder 29. One end of the suction cylinder 29 is connected to an external negative pressure device (such as a negative pressure aspirator) via a flexible tube 14, while the other end is fixed to a mounting plate 30. One end of a suction tube 31 is fixedly inserted through this mounting plate 30 and connected to the interior of the suction cylinder 29. The other end of the suction tube 31, the end inserted into the patient's body, is fixed to a sealing plate II 35. The sealing plate II 35 has multiple small suction holes 34 for aspirating waste fluid. On the outer wall of the suction pipe 31, near the sealing plate II 35, multiple pressure relief holes 36 are provided. Inside the suction pipe 31, a convex pipe 37 is fixedly installed. The structure of the convex pipe 37 can be regarded as a combination of a circular annular plate perpendicular to the pipe axis and an annular cylinder extending along the pipe axis and connected to the inner edge of the circular annular plate. An annular space, namely an annular groove 38, is formed between the outer wall of the convex pipe 37 and the inner wall of the suction pipe 31. A piston plate 39 is provided in the annular groove 38. The structural design of the piston plate 39 allows it to make contact with the outer wall of the annular cylinder of the convex pipe 37 on the inner side. Currently, a sealed sliding connection is achieved, and a sealed sliding connection is also achieved on the outer side and the inner wall of the suction tube 31. On one side of the piston plate 39, that is, the side facing the sealing plate II 35, a sealing ring 42 is fixedly connected. The sealing ring 42 slides against the inner wall of the suction tube 31, and its position corresponds to the pressure relief hole 36. In the initial state, under the pushing force of the spring II 40, the sealing ring 42 just covers and seals these pressure relief holes 36. On the other side of the piston plate 39, that is, the side away from the sealing plate II 35, multiple springs II 40 are fixedly connected by multiple spring seats. The other ends of these springs II 40 are also connected by springs. The seat is fixed on the side wall of the annular slide groove 38. The function of the spring II 40 is to always push the piston plate 39, so that it drives the sealing ring 42 to move towards the closing plate II 35, and maintain the closed state of the pressure relief hole 36. According to the design requirements of this embodiment, the spring II 40 can be a compression spring. The specific parameters need to ensure that it remains closed under normal negative pressure, but can be pushed open under abnormal high pressure. A through hole II 41 is provided on the side wall of the annular slide groove 38. This through hole II 41 allows the internal space of the annular slide groove 38 to be connected with the internal main channel of the liquid extraction tube 31 at a specific position for transmitting negative pressure.

[0058] Reference Figure 9For ease of operation, a miniature camera 33 is fixed to the outer wall of the suction tube 31 via a mounting plate 32. The camera 33 faces the end of the suction tube 31, and the video it captures can be transmitted to an external monitor to help medical personnel observe the situation inside the vagina in real time and accurately locate the waste fluid accumulation point. The mounting plate 32 is also equipped with a miniature air nozzle (not shown in the figure), which is connected to an external air source and is used to blow the lens of the camera 33 before inserting the suction tube 31 to remove any possible rinsing fluid and ensure a clear field of view; alternatively, the camera 33 can be a one-piece molded miniature industrial camera with a built-in waterproof rating.

[0059] During the aspiration procedure, medical personnel hold the aspiration cylinder 29 or aspiration tube 31 and, guided by the camera 33, gently insert the end of the aspiration tube 31 into the patient's vagina. The sealing plate II 35 is then accurately placed in the lower part of the vagina and the posterior fornix, where a temporary small pool of waste fluid naturally collects after flushing. The negative pressure device is then activated, creating negative pressure inside the aspiration cylinder 29 and aspiration tube 31. Under this negative pressure, the waste fluid in the small pool is drawn into the aspiration tube 31 through the suction holes 34 on the sealing plate II 35 and collected via the aspiration cylinder 29 and the tubing 14. During the process of transferring the fluid to the waste bottle, if the suction hole 34 accidentally adheres to the soft, moist vaginal mucosa, the suction hole 34 will be blocked. At this time, the negative pressure inside the suction tube 31 and the suction cylinder 29 will increase sharply and instantaneously. This sharply increased negative pressure will be quickly conducted to the annular groove 38 through the through hole II 41 and act on the piston plate 39. When this abnormal negative pressure force is greater than the preset elastic force of the spring II 40, it will overcome the resistance of the spring II 40 and pull the piston plate 39 and the sealing ring 42 backward together. The backward movement of the sealing ring 42 will cause it to... The previously covered pressure relief hole 36 is now exposed. Once exposed, outside air (or any small amount of liquid that may be present) will immediately rush into the suction tube 31 through these holes. The influx of air quickly disrupts the high vacuum inside the suction tube 31, causing the negative pressure at the suction hole 34 to drop sharply or even disappear. The adsorbed vaginal mucosa loses its strong negative pressure suction and, relying on its own elasticity and tissue tension, will naturally and undamagedly detach from the suction hole 34. After the mucosa detaches, the suction hole 34 becomes unobstructed again, and the negative pressure inside the suction tube 31 returns to normal. The pressure quickly returns to normal. At this point, the negative pressure in the annular groove 38 also disappears, and the elastic force of spring II 40 takes over again, pushing the piston plate 39 and sealing ring 42 forward to re-close the pressure relief hole 36. The entire suction system then returns to normal operation and can continue to suction waste liquid. This automatic pressure relief and reset process is completed instantly, effectively preventing iatrogenic damage such as congestion, purpura, or even tearing and bleeding of the patient's fragile reproductive tract mucosa caused by excessive negative pressure or prolonged suction, and greatly improving the safety of operation.

[0060] Reference Figure 2 and Figure 5 To optimize the operation process and improve ease of use, this sterilizer also includes some auxiliary designs. A footrest 6 is welded to the top of each of the two armrests 4. When the patient sits on the spherical seat 7, they can place their feet on the two footrests 6 respectively. This position allows for full exposure of the patient's perineum and vaginal opening, providing a clear view and convenient operating path for subsequent cleaning and suction operations by medical personnel. Each of the two armrests 4 also has a mounting ring 12 fixed to its top. When not in use, the cleaning cylinder 13 and the suction cylinder 29 can be placed in these two mounting rings 12 respectively. The mounting rings 12 provide support, ensuring the cleaning cylinder 13 and the suction cylinder 29 are securely placed for easy access by medical personnel. As mentioned earlier, the cleaning cylinder 13 and the suction cylinder 29 are each connected to external equipment via a flexible hose 14. One hose connects to a peristaltic pump for fluid supply, and the other connects to a negative pressure device for suction.

[0061] In another embodiment: Refer to Figure 6 and Figure 7 Inside the sliding ring 16, there is also a fixed inner tube 21. This inner tube 21 is located on one side of the rotating shaft 25 and the turbine 26. A through hole I 22 is opened inside the inner tube 21. The through hole I 22 is the main channel through which the flushing fluid flows. The shape of the through hole I 22 is designed so that the diameter is larger at the end near the closed plate I 20 and smaller at the end near the turbine 26. This tapered structure can reduce the cross-sectional area of ​​the flushing fluid when it flows through the inner tube 21. According to the principle of fluid continuity, this will increase the flow velocity of the flushing fluid. A spiral guide plate 28 is also fixedly installed on the inner wall of the through hole I 22. When the flushing fluid flows through, the spiral guide plate 28 will guide the liquid to generate a rotating flow.

[0062] Due to the tapering structure of the through-hole I22 and the internal spiral guide plate 28, the flushing fluid is accelerated and forms a spiral water flow. This water flow with momentum and rotational characteristics then impacts the turbine 26. The impact force of the water flow drives the turbine 26 to start rotating. The rotation of the turbine 26 is transmitted to the turntable 23 through the rotating shaft 25, causing the turntable 23 to rotate slowly inside the vagina.

[0063] A method for using a sterilizing device for female assisted reproductive care includes the following steps:

[0064] S1. Before the nursing procedure, the patient sits on the spherical seat 7 of the nursing chair, with his back against the backrest 2 and the spherical pad 3 providing support for his lower back. The patient places his feet on the footrests 6 at the top of the two armrests 4. This position fully exposes the patient's perineum and vaginal opening, providing a convenient operating path for subsequent cleaning and suction procedures.

[0065] S2. When the patient sits down, their buttocks directly contact and compress the inner ring airbag 8 in the seat cushion mechanism. The inner ring airbag 8 is filled with gas. Under the action of the patient's own weight, the inner ring airbag 8 is compressed, and its internal air pressure increases. Since the bottom of the inner ring airbag 8 and the bottom of the outer ring airbag 10 are fixedly connected and interconnected through multiple connecting pipes 11, the compressed gas flows from the inner ring airbag 8 into the outer ring airbag 10 through the connecting pipes 11. As the gas flows in, the outer ring airbag 10 gradually inflates. The inflated outer ring airbag 10 fits tightly against the gap between the patient's groin and buttocks and the annular storage tray 9, forming a personalized flexible physical sealing barrier. The sealing barrier can effectively prevent the flushing fluid flowing out of the vaginal opening from leaking out along the gap between the body and the seat during the subsequent flushing process. The waste fluid flowing out of the vagina temporarily gathers in the annular gap formed by the inner ring airbag 8, the annular storage tray 9, and the inflated outer ring airbag 10.

[0066] S3. The waste liquid collected in the annular gap is guided downward through the guide channel 43 set on the outer wall of the spherical seat 7. The top opening of the guide channel 43 is directly opposite the bottom of the annular gap, receiving the waste liquid and guiding it to the bottom. The bottom end of the guide channel 43 is located above the collection plate 5 fixed on the top of the base 1. The waste liquid finally falls into the collection plate 5 to achieve centralized collection.

[0067] S4. Before the flushing operation begins, the medical staff holds the cleaning tube 13 and gently inserts the end with the rotating disc 23 into the patient's vagina through the vaginal opening. The rear end of the cleaning tube 13 is connected to an external peristaltic pump via a flexible tube 14. After the peristaltic pump is started, the flushing fluid enters the cleaning tube 13 through the flexible tube 14 under the pressure of the pump. The flushing fluid first reaches the fixing ring 15. In the initial state, the sealing plate I 20 is tightly pressed against the center hole of the fixing ring 15 by the pushing force of the spring I 19, sealing the flow channel of the flushing fluid. As the peristaltic pump continues to work, the pressure of the flushing fluid inside the cleaning tube 13 gradually increases. When the force of the liquid pressure acting on the sealing plate I 20 is greater than the elastic force of the spring I 19, the flushing fluid pushes the sealing plate I 20 away from the fixing ring 15. As the sliding ring 16 moves in the direction of 5, the sealing plate I 20 is fixedly connected to the sliding ring 16 via the vertical rod. Therefore, the movement of the sealing plate I 20 drives the entire sliding ring 16, inner tube 21, cross mounting bracket 24, rotating shaft 25 and turntable 23 to move synchronously towards the inside of the vagina. At this time, the turntable 23 extends out from the port at the front end of the cleaning tube 13 and enters the vaginal space. At the same time, the sealing plate I 20 disengages from the fixed ring 15, releasing the sealing of the fixed ring 15. The flushing fluid can continue to flow forward through the fixed ring 15. During the movement of the sliding ring 16, the retaining ring 18 fixedly sleeved on the outer wall of the sliding ring 16 slides in the annular groove 17 on the inner wall of the cleaning tube 13 and compresses the spring I 19 sleeved on the outer wall of the sliding ring 16. The spring I 19 stores elastic potential energy.

[0068] S5. The flushing fluid continues to flow forward through the fixed ring 15 and enters the inner tube 21 fixed inside the sliding ring 16. The inner tube 21 has a through hole I 22. The diameter of the through hole I 22 near the closed plate I 20 is larger than the diameter near the turbine 26, forming a tapered structure. According to the principle of fluid continuity, when the flushing fluid flows through this tapered channel, its flow cross-sectional area decreases and its flow velocity increases. At the same time, a spiral guide plate 28 is fixedly installed on the inner wall of the through hole I 22. Under the guidance of the spiral guide plate 28, the high-speed flushing fluid changes from a straight flow to a spiral flow. The flushing fluid with high kinetic energy and rotational momentum then impacts the turbine 26 fixed at the end of the rotating shaft 25. The impact force of the water flow on the turbine blades of the turbine 26 generates torque, driving the turbine 26 to start rotating around its own axis. The rotational motion of the turbine 26 The rotation of the rotating shaft 25, which is fixedly connected to the rotating shaft 25, is at the center of the cross-shaped mounting bracket 24. This rotation drives the turntable 23, which is fixedly connected to the other end of the rotating shaft 25, to rotate synchronously. The outer wall of the turntable 23 and the side facing the patient are provided with multiple spray holes 27. The rinsing fluid is sprayed out from these spray holes 27 under pressure. As the turntable 23 rotates continuously during the rinsing process, the spray direction of the spray holes 27 changes continuously, so that the rinsing fluid can rinse and clean the vaginal wall from multiple angles, including the longitudinal folds and the depths of the fornix. During the entire rinsing process, the extension, rotation and repositioning of the turntable 23 are entirely driven by the flow pressure of the rinsing fluid itself, without the intervention of any motor or other electrical components, which fundamentally eliminates the potential safety hazard of electric leakage that may be caused by using electrical appliances in a humid environment.

[0069] S6. When the flushing operation is completed, the medical staff turns off the peristaltic pump, and the pressure of the flushing fluid disappears. At this time, the compressed spring I19 releases its stored elastic potential energy, pushing the retaining ring 18 to slide in the reverse direction in the annular groove 17. The retaining ring 18 drives the sliding ring 16, the sealing plate I20, the inner tube 21 and the turntable 23 to move away from the inside of the vagina and reset. The sealing plate I20 re-abuts against the fixing ring 15, sealing the flushing fluid channel. At the same time, the turntable 23 is returned to the inside of the cleaning cylinder 13, waiting for the next use. At this time, the residual flushing fluid and shed tissue debris in the vagina gather at the posterior fornix of the vagina.

[0070] S7. After rinsing, waste fluid needs to be aspirated. Before aspiration, the operator can turn on the external air source and pre-clean and dry the lens of camera 33 through a miniature air nozzle to ensure a clear image of the inside of the vagina. The medical staff holds the aspiration tube 29 and, with the assistance of the camera 33 fixed to the outer wall of the aspiration tube 31, inserts the end of the aspiration tube 31 into the patient's vagina through the vaginal opening. The real-time video image transmitted to the monitor by the camera 33 allows the medical staff to accurately position the sealing plate II 35 at the end of the aspiration tube 31 to the lower part of the vagina and the posterior fornix. This area is a temporary small pool formed by the natural collection of waste fluid after rinsing.

[0071] S8. After positioning, activate the external negative pressure device connected to the rear end of the suction cylinder 29 via the hose 14. The negative pressure device generates a stable negative pressure environment inside the suction cylinder 29 and the suction tube 31. Under this negative pressure, the waste liquid in the small liquid pool is sucked into the suction tube 31 through multiple suction holes 34 on the sealing plate II 35, and then drawn into the waste liquid collection container via the suction tube 31, the suction cylinder 29, and the hose 14. During the suction process, if a suction hole 34 on the sealing plate II 35 accidentally adheres to the soft and moist vaginal mucosa, the suction hole 34 will be blocked. The blockage of the suction hole 34 causes the negative pressure inside the suction tube 31 and the suction cylinder 29 to rise sharply and instantaneously. The abnormally increased negative pressure is rapidly conducted to the internal space of the annular groove 38 through the through hole II 41 on the side wall of the annular groove 38 between the inner wall of the suction tube 31 and the convex tube 37, and acts on the sealing sliding connection within the annular groove 38. When the negative pressure applied to the piston plate 39 is greater than the preset elastic force of the multiple springs II 40 connected to it, the negative pressure overcomes the elastic force of the springs II 40 and pulls the piston plate 39 away from the sealing plate II 35. A sealing ring 42 is fixedly connected to one side of the piston plate 39. The sealing ring 42 slides against the inner wall of the suction tube 31. In the initial state, it covers and seals the pressure relief hole 36 on the outer wall of the suction tube 31. The retraction of the piston plate 39 drives the sealing ring 42 to retract synchronously, thereby exposing the pressure relief hole 36, which was originally covered, to the internal space of the suction tube 31. After the pressure relief hole 36 is exposed, outside air rushes into the inside of the suction tube 31 through the hole, which quickly destroys the high vacuum inside the suction tube 31. The negative pressure at the suction hole 34 drops sharply or even disappears. After losing the strong negative pressure suction, the vaginal mucosa that was adsorbed naturally and undamagedly falls off from the suction hole 34 by relying on the elasticity and tension of its own tissue.

[0072] S9. After the mucosa sloughs off, the suction hole 34 becomes unobstructed again, and the negative pressure in the suction tube 31 quickly returns to normal. At this time, the abnormal negative pressure transmitted from the through hole II 41 in the annular groove 38 disappears, and the elastic force of the spring II 40 regains dominance, pushing the piston plate 39 and the sealing ring 42 to move and reset towards the sealing plate II 35. The sealing ring 42 covers and seals the pressure relief hole 36 again, and the negative pressure environment inside the suction system is restored. The waste liquid suction continues. This automatic pressure relief and reset mechanism is completed instantly, effectively preventing iatrogenic damage such as congestion, purpura, or even tearing and bleeding of the reproductive tract mucosa caused by prolonged or excessive negative pressure suction.

[0073] The sliding parts of this device, such as the sliding ring and cleaning cylinder, piston plate and annular groove, and retaining ring and annular groove, are all lubricated with medical food-grade grease. After use, each sliding part should be rinsed and cleaned with medical disinfectant. The integrity of the seals should be checked every 30 uses. If aging or jamming of the seals occurs, the seals should be replaced in time.

[0074] However, as is well known to those skilled in the art, the working principle and wiring method of camera 33 are conventional means or common knowledge, and will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0075] All parts that come into contact with the human body are made of medical-grade materials that meet the requirements of GB / T16886. The outer wall of the cleaning tube and the outer wall of the suction tube are covered with medical soft silicone sleeves, and the insertion end is rounded and smoothed to meet clinical safety requirements.

It fits the root of the thigh and forms a seal with the ring storage tray (9). The waste liquid collects in the ring gap and flows into the collection tray (5) through the guide channel (43). Insert the cleaning tube (13) into the vagina, and connect the peristaltic pump at the rear end through the hose (14). After starting, the flushing fluid pressure overcomes the spring I (19) to push open the sealing plate I (20), which drives the sliding ring (16), inner tube (21), cross mounting bracket (24) and turntable (23) to move forward and extend. At the same time, the retaining ring (18) slides in the annular groove (17) to compress the spring I (19).
