Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a vaginal douching device. Background Art

[0002] Gynecological vaginal irrigation technology plays an irreplaceable and important role in clinical treatment and personal hygiene maintenance. As an important means of local treatment, vaginal irrigation can effectively remove pathogenic microorganisms, abnormal secretions and drug residues, and improve the vaginal microenvironment. Traditional vaginal irrigation devices are mainly divided into two categories: straight-head squeeze-type irrigators and electric irrigators. Straight-head squeeze-type irrigators have a simple structure and consist of a irrigating bottle and a irrigating tube connected by a threaded bottle mouth. The operation method is to manually squeeze the irrigating bottle to generate liquid pressure. Electric irrigators use electricity to generate a stable liquid flow, but the overall device is complex and requires frequent cleaning and maintenance. From an anatomical perspective, the vaginal wall has a rich transverse fold structure and great elasticity. The width of the vagina varies depending on the physiological state. Clinical data show that the width of the vagina of non-parous women is significantly different from that of parous women. Existing douches cannot completely clean to the same extent according to the differences between different populations. Moreover, only the flushing path from the vaginal vault to the vaginal opening can more effectively remove deep secretions and pathogens. Especially for critically ill patients, such as those with pseudomembranes on the vaginal mucosa, they need to first flush with warm water to remove the pseudomembrane and then receive drug treatment. This step-by-step flushing process leads to lengthy switching and low efficiency during treatment. Existing devices still have many shortcomings in achieving this flushing path.

[0003] Existing flushing devices have many technical limitations. Straight-head squeeze-type irrigators are difficult to operate and prone to overflow during the process of liquid infusion. Manual squeezing will also cause unstable flow, and the flushing effect is significantly affected by the operator's technical level. In the busy working environment of medical institutions, this operational difficulty leads to reduced work efficiency of medical staff; and in the patient's home self-care scenario, it is difficult for non-professionals to master the correct techniques, which often leads to incomplete flushing or improper operation. In the case of complex vaginal fold structures, it is difficult to achieve a comprehensive and thorough flushing path. Fixed-point flushing cannot be compared with moderate swinging in terms of the effect of clearing secretions between vaginal folds. Even if traditional electric irrigators can provide a stable liquid flow, if the contact area between the flushing liquid and the vaginal mucosa is not increased, flushing dead corners are still difficult to avoid. Existing devices generally ignore individual differences in vaginal width and fail to provide adaptive flushing solutions. At the same time, cleaning and maintenance work is cumbersome and there is a risk of cross-infection. Summary of the Invention

[0027] Beneficial Effects of the Present Invention: By combining this invention with a straight-head squeeze-type irrigator, it significantly improves clinical effectiveness and operational ease. The liquid storage unit leverages the compressibility of the straight-head squeeze-type irrigator and a check valve to implement pull- and push-type aspiration mechanisms, respectively addressing the difficulties of difficult drug infusion and overflow in conventional devices. It also ensures stable drug flow during the irrigation process and enhances the impact on secretions. The irrigation unit's three-mode design adapts to various clinical scenarios. The inside-out and top-down irrigation paths and adjustable swing mechanism are well-suited to the characteristics of vaginal anatomy. Because the irrigation tube head is closer to the radial mucosa of the vagina and the overall contact area is larger, the irrigation force is stronger at the same fluid output pressure, while also fully irrigating and clearing secretions between transverse folds. Furthermore, the modular structure of this device supports the compatible use of traditional irrigation bottles and irrigation tubes, making it disposable and cleaning-free, while also providing a check valve to isolate the liquid inside and outside the bottle, preventing contamination and allowing for multiple uses, reducing usage costs and the risk of cross-infection. For patients who require step-by-step flushing, such as those with critical illnesses, the device's rapid solution replacement significantly improves operational and treatment efficiency. Furthermore, the adjustable swing amplitude of the flushing tube allows for tailored cleaning regimens based on individual patient differences, alleviating discomfort during treatment and improving patient compliance.

[0055] The support bracket 14 includes a moving groove 141 disposed on a surface thereof and a pair of blocking pieces 142 fixed to side walls of the moving groove 141 .

[0056] Furthermore, the infusion assembly 15 includes a sealing cover 151, a three-way pipe 152 fixed on the end surface of the sealing cover 151, a pair of check valves 153 fixed to two of the pipe openings of the three-way pipe 152 and with opposite passages, and a hose 154 fixed to the other end of the check valve 153.

[0057] Furthermore, the infusion assembly 15 includes a sealing cover 151, a three-way valve fixed at the end surface of the sealing cover 151, and a pair of hoses 154 fixed to the remaining two valve ports of the three-way valve; the three-way valve can control the connection between any two routes through the valve core.

[0060] The worm 244 includes a fastening bolt 2441 penetrating through the side wall thereof;

[0061] The worm 244 is located between the two concentric guide arms 231 .

[0062] Furthermore, the swing assembly 25 includes an adjustable swing arm 251 fixed to the end of the movable shaft 233 and a swing seat 252 penetrating the through slot 235;

[0063] The adjustable swing arm 251 includes an open slot 2511 formed on its surface, an adjusting bolt 2512 sleeved within the open slot 2511 , and a movable post 2513 engaged with the adjusting bolt 2512 ;

[0064] The swing seat 252 includes a swing arm 2521, a waist-shaped hole 2522 set through the center of the swing arm 2521, an arc block 2523 set at the connection of the swing arm 2521, a connecting pipe 2524 fixed to the bottom surface of the swing seat 252, a nozzle 2525 fixed to the other surface of the swing seat 252, and an arc limit plate 2526 set below the arc block 2523.

[0065] Furthermore, it also includes a plug-in battery 3 plugged into one end of the motor cabin 111.

[0066] Reference Figure 14 This embodiment also provides a straight-head squeeze-type flusher, which includes a flushing bottle 4 and a flushing tube 5 . The flushing bottle 4 cooperates with the sealing cover 151 , and the flushing tube 5 cooperates with the connecting ring 26 .

[0067] In one embodiment provided herein, the housing 11 is cylindrical, extending from end to end. A motor cabin 111 is secured to the bottom of the housing 11. The motor is secured within the cabin 111 via a motor bracket, with the shaft facing upward and extending into the housing 11. The motor is also equipped with a speed regulating plate, located on the side outer wall of the cabin 111, for opening and closing the motor and controlling its speed.

[0068] Preferably, a plug-in battery 3 can be installed at the bottom of the motor cabin 111 to power the motor, and the battery pack also has a power display screen.

[0069] As an optional implementation, the motor used is a 600r / min DC brushless reduction motor.

[0070] As an optional implementation, the built-in 12V DC lithium battery pack of the plug-in battery 3 supports charging and discharging.

[0071] Preferably, a screw slide 12 is also fixed inside the housing 11. The screw slide 12 is composed of a screw, a screw nut, a slide, and a pair of linear guide rails. This is a technical means commonly used by those skilled in the art. Specifically, the screw is fixedly connected to the motor shaft end through a coupling, and the other end of the screw is radially fixed by a bearing seat, and the bearing seat is fixed on the inner wall of the housing 11. There are also two straight rods on both sides of the screw that are fixed to the inner walls of the housing 11 on both sides and are symmetrically distributed. The screw nut cooperates with the screw, the center of the slide is fixed and sleeved on the screw nut, and the two sides of the slide are sleeved on the two straight rods through linear bearings. When the motor rotates, it can drive the slide to move back and forth along the axis of the screw.

[0072] As an alternative embodiment, the screw slide 12 utilizes a screw pair with a lead of 1 mm. When the effective stroke of the screw nut is 60 mm, the motor drives the screw nut at a speed of 10 mm / s, completing a single unidirectional movement in approximately 6 seconds. Since the rinse bottle 4 is approximately 70 mm long before the threaded opening and approximately 10 mm long after compression, the effective compression distance of the rinse bottle 4 is approximately 60 mm, which is also the effective stroke of the screw nut.

[0073] Preferably, a support seat 13 is fixed to the surface of the slide. The support seat 13 is plate-shaped, with both sides extending toward the linear guide rail. At least a pair of symmetrical and continuous adjustment grooves 131 are provided on both side surfaces of the support seat 13. Pressure rods 132 can pass through the adjustment grooves 131 and can be fixed at any position of the adjustment grooves 131. The surface of the support seat 13 is used to support the bottom of the rinse bottle 4, and the two symmetrically distributed pressure rods 132 can clamp the corrugated grooves on the rinse bottle 4. When the screw nut moves, the support seat 13 can be driven by the slide to move linearly, and the rinse bottle 4 is then compressed and stretched by the pressure rods 132, thereby controlling the inflow and outflow of liquid inside the rinse bottle 4.

[0074] As a preferred embodiment, a gasket that fits the curvature of the washing bottle 4 is provided at the position where the surface of the supporting seat 13 contacts the washing bottle 4, and a push plate is fixed on the surface of the supporting seat 13 at the bottom of the washing bottle 4, which can ensure the effectiveness of the compression force and force application position when compressing the washing bottle 4.

[0075] As a preferred embodiment, the pressing rod 132 is selected from full-thread screws, and the pressing rod 132 is fixed by installing two nuts on both sides of the notch of the adjusting groove 131. In addition, the contact friction of the pressing rod 132 on the flushing bottle 4 can be increased.

[0076] Preferably, a support bracket 14 is also fixed in the axial direction of the housing 11. When the rinse bottle 4 is placed into the interior through the opening 112 opened in the side wall of the housing 11, and the bottom of the rinse bottle 4 contacts the surface of the push plate, the support bracket 14 is located at the connection between the threaded opening on the rinse bottle 4 and the bottle body. The two ends of the support bracket 14 are fixedly connected to the inner wall of the housing 11. A through-movement groove 141 is also formed on the surface of the support bracket 14, and a baffle 142 is fixed to the support bracket 14 in the vertical direction using conventional bolts and nuts. The conventional bolts and nuts are moved in the moving grooves 141 to control the position of the two baffles 142. The baffles 142 and the support bracket 14 form a semi-enclosed structure for clamping the connection between the threaded opening on the rinse bottle 4 and the bottle body.

[0077] Preferably, the infusion assembly 15 is directly placed inside the housing 11, located between the support bracket 14 and the end opening of the housing 11. The sealing cap 151 can be screwed and sealed with the flushing bottle 4. A tee pipe 152 is fixed to the outer end surface of the sealing cap 151 and is interconnected. Two check valves 153 are also fixed to and connected to the remaining two pipes of the tee pipe 152. The two check valves 153 are connected in opposite directions. In addition, a hose 154 is fixed to the other end of each check valve 153.

[0078] When the flushing bottle 4 is connected to the infusion assembly 15, when the compressed flushing bottle 4 is stretched by the pressure rod 132, since the conduction directions of the two check valves 153 are opposite, only one check valve 153 can perform the suction action at this time, and the other is not connected, and the external liquid medium can be sucked through the corresponding hose 154; and when the flushing bottle 4 is filled with liquid medium, when the bottom of the flushing bottle 4 is pushed by the above-mentioned push plate and pressure rod 132, only one check valve 153 can perform the discharge action, and the corresponding hose 154 here is used for liquid supply.

[0079] The hose 154 used for suction can be led out from the storage port 112 and snapped into the buckle on the outer wall of the shell 11 for storage, and the other hose 154 is led out from the end opening of the shell 11.

[0080] As an optional embodiment, the three-way pipe 152 and the check valve 153 can be replaced with a three-way valve. One of the valve ports of the three-way valve is fixedly connected to and communicates with the outer end surface of the sealing cover 151, and the other two valve ports are directly fixedly connected to the two hoses 154. The valve core in the three-way valve can switch the connection between any two valve ports. Therefore, when suction and discharge operations are required, the two communication paths need to be switched specifically.

[0081] As an optional implementation, the three-way valve can be a three-way valve made of PC material with a pagoda hose socket, and the diversion of the liquid medium can be controlled by switching.

[0082] Preferably, the support end 21 is a prism-shaped or truncated cone-shaped shell structure with two through-holes. Two symmetrical parallel plates 211 are fixed on either side of the opening at the top of the support end 21. The parallel plates 211 extend in a direction that intersects and is approximately perpendicular to the axis of the housing 11. Two pairs of symmetrically distributed shaft seats 212 are fixed on opposing surfaces of the two parallel plates 211, with the parallel optical axis 22 mounted on each pair of shaft seats 212.

[0083] Preferably, a long keyway 221 is provided on the side wall of the parallel optical axis 22, extending from end to end. A prism 222 is fixed to the end of the parallel optical axis 22, and a limit plate 223 is fixed at the connection between the two. Therefore, when the parallel optical axis 22 passes through any pair of shaft seats 212, it can be positioned by the limit plate 223. The fixing block 224 is installed on the other surface of the limit plate 223, can be passed through by the parallel optical axis 22, and is fixed to the parallel plate 211 to limit the axial position of the parallel optical axis 22. It should be noted that both parallel optical axes 22 can rotate circumferentially after being limited.

[0084] As a preferred embodiment, the prism 222 is in the shape of a quadrangular prism or a hexagonal prism.

[0085] Preferably, the linear slider 23 has two pairs of guide arms 231 fixed on its surface and distributed at four corners, which can be respectively mounted on the outer walls of the two parallel optical axes 22, so that the linear slider 23 can move back and forth along the axial direction of the parallel optical axes 22.

[0086] A movable shaft 233 is passed through and sleeved on the center position of the linear slider 23. A positioning piece 232 is also provided on the end of the movable shaft 233 away from the linear slider 23. The positioning piece 232 is used to limit the unilateral axial position of the linear slider 23, but does not affect the circumferential rotation of the movable shaft 233. The positioning piece 232 is fixed to the surface of the linear slider 23 by conventional bolts.

[0087] In addition, an arc block 234 is fixed on the outward surface of the linear slider 23 . The surface of the arc block 234 is used for guidance, and a through slot 235 is formed on the arc block 234 .

[0088] Preferably, a worm gear 241 and a gear 242 are also fixed to the movable shaft 233, with the gear 242 positioned proximate to the positioning plate 232 and the worm gear 241 positioned proximate to the inward surface of the linear slider 23. The rack 243 can be fixed to any parallel plate 211 and positioned on the inner side of the parallel plate 211, with the tooth surface of the rack 243 facing the gear 242, and the two meshing with each other. The worm 244 can be mounted on any parallel optical axis 22 and positioned between two concentric guide arms 231. It is axially constrained by the guide arms 231 and can mesh with the worm gear 241.

[0089] It should be noted that a fastening bolt 2441 is installed in the side wall of the worm 244, which is used to fix the worm 244 on the parallel optical axis 22. However, different from the traditional usage method, a gap needs to be left between the bottom of the fastening bolt 2441 and the surface of the long keyway 221, that is, in the absence of the constraint of the linear slider 23, the rotation of the parallel optical axis 22 can drive the worm 244 to rotate synchronously, and at this time the worm 244 can also move axially along the parallel optical axis 22.

[0090] When the parallel optical axis 22 with the worm 244 installed rotates, it can drive the worm 244, thereby driving the worm wheel 241 to rotate, and the worm wheel 241 drives the gear 242 to rotate through the movable shaft 233, and then moves through the engagement of the gear 242 and the rack 243, and then drives the entire linear slider 23 to move axially along the two parallel optical axes 22. Finally, the worm 244, because it is between the two guide arms 231, also moves in the same direction.

[0091] As a preferred embodiment, the parameters selected for the worm wheel 241 and the worm 244 are module 0.5 and speed ratio 20. That is, when the speed of the parallel optical axis 22 is the same as that of the motor, the speed of the worm wheel 241 is 30 r / min, and the gear 242 also has the same speed.

[0092] As a preferred embodiment, the parameters selected for gear 242 are module 0.5, number of teeth 20, and the module of rack 243 is consistent with that of gear 242. Calculation shows that the displacement corresponding to one rotation of gear 242 is 31.4 mm / r, and the displacement of gear 242 per second is 15.7 mm / s, that is, the moving speed of linear slider 23 is 15.7 mm / s.

[0093] The length of the flushing tube 5 excluding the threaded opening is about 70 mm, that is, the effective stroke of the linear slider 23 is 70 mm, and the entire stroke is completed in about 4.45 seconds, that is, when the head of the flushing tube 5 exits the vaginal opening, there is still 1.5 seconds to continue flushing the vulva.

[0094] Preferably, the flexible shaft core 27 is a flexible power transmission member, one end of which is fixedly connected to the end of the lead screw via a coupling, while the other end is plugged into the prism 222 on the parallel optical axis 22 via a joint 271. Therefore, the joint 271 is fixedly connected to the other end of the flexible shaft core 27, and the surface of the joint 271 also reserves a prismatic hole of the same shape as the prism 222. Therefore, when the lead screw rotates, it can synchronously drive the parallel optical axis 22 to rotate through the flexible shaft core 27.

[0095] Preferably, the center of the lower surface of the adjustable swing arm 251 is fixed to the top of the portion of the movable shaft 233 exposed from the linear slider 23, so that when the movable shaft 233 rotates, the adjustable swing arm 251 is driven to rotate.

[0096] An open groove 2511 is also provided on the outer surface of the adjustable swing arm 251, and an adjusting bolt 2512 is placed inside. The neck of the adjusting bolt 2512 is supported by the annular protrusion in the open groove 2511, and the head is supported by the groove wall of the open groove 2511. Therefore, by limiting the head of the adjusting bolt 2512, the axial limitation of the entire adjusting bolt 2512 is achieved.

[0097] The open slot 2511 has a circular cross-section, and its opening on the surface of the adjustable swing arm 251 is narrower than the slot body. The movable post 2513 conforms to the shape of the slot body and fits over the stud portion of the adjusting bolt 2512, threadedly engaging with each other. The head of the movable post 2513 extends out of the opening on the surface of the adjustable swing arm 251. Rotating the adjusting bolt 2512 causes the movable post 2513 to move axially along the opening, facilitating adjustment of its position.

[0098] Preferably, a swing arm 2521 is fixed to one side of the swing seat 252, and the two are perpendicular to each other. A waist-shaped hole 2522 is formed through the swing arm 2521, and a circular arc block 2523 is fixed at the connection between the swing arm 2521 and the swing seat 252, the bottom of which is able to fit the arc surface of the inner wall of the arc block 234. The swing arm 2521 can pass through the through slot 235, and the column head of the movable column 2513 just passes through the waist-shaped hole 2522 and is tangent to the two side walls of the waist-shaped hole 2522. The circular arc limiting piece 2526 is fixed to the side wall of the circular arc block 2523, and the arc surface of the circular arc limiting piece 2526 fits the arc surface of the outer wall of the arc block 234, which is used to limit the swing seat 252 along the axis of the swing arm 2521.

[0099] Preferably, the connecting ring 26 is fixed on the surface of the swing seat 252 facing away from the movable shaft 233, and a nozzle 2525 is also fixed at the center of the connecting ring 26, and a connecting pipe 2524 is fixed at the center of the surface facing the movable shaft 233. The connecting pipe 2524 is connected to the nozzle 2525, and the other end of the hose 154 for discharging liquid is connected to and fixed to the connecting pipe 2524.

[0100] The connecting ring 26 is used for threaded connection with the flushing pipe 5 .

[0101] Reference Figure 13 When the adjustable swing arm 251 rotates, the column head part of the movable column 2513 can drag the swing arm 2521 to move, and the corresponding swing seat 252 will swing back and forth with the center O and along the trajectory of the arc block 234. At this time, the flushing pipe 5 will move back and forth within the swing width D.

[0102] It's important to note that vaginal width is highly flexible, with the normal range varying depending on physiological status. The vaginal width of nulliparous women is approximately 1.5-2.5 cm, while that of fertile women is 2.5-4 cm. Therefore, D3 is set to the maximum swing width, approximately 40 mm, D2 is set to 30 mm, and D1 is set to 20 mm. The swing range D depends on the position of the movable column 2513 on the adjustable swing arm 251, that is, the size of the trajectory C of the movable column 2513 during its circular motion. Trajectory C3 corresponds to the swing width of D3, C2 corresponds to D2, and C1 corresponds to D1.

[0103] The adjustable swing arm 251 has graduated grooves on both sidewalls. These grooves correspond to the three positions of the center of the movable column 2513, corresponding to the positions when the flushing tube 5 swings 40mm, 30mm, and 20mm, for reference. Due to individual differences, it is necessary to manually adjust the adjustment bolt 2512 to control the movable column 2513 to the position that suits your needs and alleviate discomfort.

[0104] As a preferred embodiment, the maximum radius trajectory of the moving column 2513 when performing circular motion is limited to trajectory C3, that is, no matter how it is adjusted, it will not exceed C3.

[0105] It should be noted that the vaginal irrigation device of the present invention can realize three modes:

[0106] When flushing the vulva, it is necessary to disconnect the connection between the soft shaft axis 27 and the parallel optical axis 22. At this time, the flushing tube 5 is not installed, and the swing seat 252 has not deflected. At this time, the flushing bottle 4 is filled by suction, and then the flushing bottle 4 is compressed by the screw slide 12. The liquid in the bottle is discharged from the nozzle 2525 through the hose 154. The nozzle 2525 is aligned with the vulva position for automatic flushing.

[0107] During traditional flushing, it is necessary to disconnect the connection between the soft shaft axis 27 and the parallel optical axis 22. At this time, the flushing tube 5 is installed, and the swing seat 252 does not deflect. At this time, the flushing bottle 4 is filled by suction, and then the flushing tube 5 is placed into the vagina. The flushing bottle 4 is then compressed by the screw slide 12, and the liquid in the bottle is sent into the flushing tube 5 through the hose 154 and the nozzle 2525. The liquid can be discharged through the hole at the end of the flushing tube 5, thereby achieving flushing of the vagina.

[0108] During all-round flushing, the flushing bottle 4 is first sucked and filled, and then the soft shaft axis 27 is connected to the parallel optical axis 22. At this time, the flushing tube 5 is installed, and the swing seat 252 does not deflect. At this time, the flushing tube 5 is placed in the vagina, and then the flushing bottle 4 is compressed by the screw slide 12. The liquid in the bottle is sent into the flushing tube 5 through the hose 154 and the nozzle 2525. At the same time, the flushing tube 5 will move back and forth according to the preset swing width and gradually withdraw from the vagina, thereby realizing all-round flushing of the vagina.

[0109] In summary, the present invention significantly improves clinical efficacy and operational ease by combining it with a straight-head squeeze-type irrigator. The liquid storage unit leverages the compressibility of the straight-head squeeze-type irrigator in conjunction with a check valve to implement a pull-and-push suction mechanism, respectively addressing the difficulties of difficult drug infusion and easy overflow in traditional devices. It also ensures the stability of the drug flow rate during the irrigating process and enhances the impact on secretions. The irrigating unit's three-mode design adapts to various clinical scenarios. The inside-out and top-down irrigating paths and the adjustable swing mechanism are well-suited to the characteristics of vaginal anatomy. Because the head of the irrigating tube is closer to the radial mucosa of the vagina and the overall contact area is larger, the irrigating force is stronger at the same liquid output pressure, while also being able to fully irrigate and remove secretions between the transverse folds. Furthermore, the modular structure of this device supports the compatible use of traditional irrigating bottles and irrigating tubes, allowing it to be treated as a disposable consumable, eliminating the need for cleaning, while also providing a check valve to isolate the liquid inside and outside the bottle, preventing contamination within the bottle and allowing for multiple uses, reducing usage costs and the risk of cross-infection. For patients who require step-by-step flushing, such as those with critical illnesses, the device's rapid solution replacement significantly improves operational and treatment efficiency. Furthermore, the adjustable swing amplitude of the flushing tube allows for tailored cleaning regimens based on individual patient differences, alleviating discomfort during treatment and improving patient compliance.

[0110] The device's ease of use not only reduces the burden on medical staff but also allows patients to easily master its use at home, expanding its application scenarios. By integrating the reservoir and flushing units, it achieves a stable supply of liquid medication, automated flushing path control, multi-mode application scenario adaptation, and low-cost consumable replacement, significantly improving the effectiveness, convenience, and safety of vaginal douching.

[0111] Therefore, the present invention has comprehensive technical advantages in improving flushing effects, simplifying operating procedures, reducing usage costs and enhancing adaptability.
