Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a vaginal irrigation 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 extrusion irrigators and electric irrigators. The straight-head extrusion irrigator has a simple structure, which is composed of an irrigation bottle and an irrigation tube connected by a screw thread at the bottle mouth, and the operation method is to manually squeeze the irrigation bottle to generate liquid pressure. The electric irrigator generates a stable liquid flow through electric drive, but its overall device is complex and requires frequent cleaning and maintenance. From an anatomical perspective, the vaginal wall has a rich transverse fold structure and a large extensibility. The width of the vagina varies according to the physiological state, and clinical data shows that there are also obvious differences in the vaginal width between nulliparous women and parous women. Existing irrigators cannot fully clean according to the differences of different populations to the same extent, and only the irrigation path from the vaginal fornix down to the vaginal orifice can more effectively remove deep secretions and pathogens. Especially for critically ill patients, such as those with a pseudomembrane on the vaginal mucosa, warm water needs to be used to wash away the pseudomembrane first, and then drug treatment is carried out. This step-by-step irrigation process leads to a long and inefficient switching during treatment. There are still many deficiencies in the existing devices in realizing this irrigation path.

[0003] Existing irrigation devices have various technical limitations. The straight-head extrusion irrigator is difficult to operate and prone to overflow during the liquid medicine perfusion process, and manual extrusion will also cause unstable flow, and the irrigation effect is significantly affected by the operator's technical level. In the busy working environment of medical institutions, this operation difficulty reduces the work efficiency of medical staff; in the scenario of patients' home self-care, non-professionals are difficult to master the correct technique, often resulting in incomplete irrigation or improper operation. In the case of a complex vaginal fold structure, it is difficult to achieve a comprehensive and thorough irrigation path. Fixed-point irrigation cannot achieve the same effect as moderate swinging in removing secretions between vaginal folds. Even if traditional electric irrigators can provide a stable liquid flow, if the contact area between the irrigation liquid and the vaginal mucosa is not increased, irrigation dead angles are still difficult to avoid. Existing devices generally ignore the individual differences in vaginal width, fail to provide an adaptive irrigation solution, and at the same time, the cleaning and maintenance work is cumbersome and there is a risk of cross-infection.

The three - mode design of the rinsing unit adapts to various clinical scenarios. The rinsing path from the inside out and from top to bottom and the swing mechanism with adjustable amplitude fit well with the characteristics of vaginal anatomy. Since the head of the rinsing tube is closer to the mucosal layer in the vaginal radial direction and has a larger overall contact area, at the same liquid output pressure, the rinsing force is stronger and it can comprehensively rinse and remove the secretions between the transverse folds. In addition, the device adopts a modular structure, which can support the compatible application of traditional rinsing bottles and rinsing tubes. It can be used as a disposable consumable, eliminating the need for cleaning, and also has a check function to isolate the liquid inside and outside the bottle, avoiding internal contamination for multiple uses, reducing the use cost and the risk of cross - infection. For those who need step - by - step rinsing, such as critically ill patients, the rapid liquid replacement effect of this device significantly improves the operation and treatment efficiency. In addition, the adjustable swing amplitude of the rinsing tube can adjust the cleaning plan according to individual patient differences, reducing the discomfort during the treatment process and improving patient compliance.

[0045] Further, it further includes a plug-in battery 3 inserted into one end of the motor cockpit 111.

[0046] Reference Figure 14 In this embodiment, a straight - head extrusion type rinser is further provided, which includes a rinsing bottle 4 and a rinsing tube 5. The rinsing bottle 4 is matched with a sealing cover 151, and the rinsing tube 5 is matched with a connecting ring 26.

[0047] In an embodiment provided by the present application, the housing 11 is a columnar housing, both the head and the tail are penetrated to the outside. A motor cockpit 111 is fixed at the bottom of the housing 11. The motor is fixed inside the motor cockpit 111 through a motor bracket, and the shaft end faces upward and extends into the housing 11. The motor is also equipped with a speed - regulating board, which is placed on the outer wall of the side of the motor cockpit 111 for turning on / off and controlling the motor speed.

[0048] Preferably, a plug - in battery 3 can be installed at the bottom of the motor cockpit 111 for supplying power to the motor. The battery pack also has a power display screen.

[0049] As an alternative embodiment, the motor used is a DC brushless reduction motor with a speed of 600 r / min.

[0050] As an alternative embodiment, the plug - in battery 3 is internally provided with a 12V DC lithium - battery pack, which supports charging and discharging.

[0051] Preferably, a lead - screw slide 12 is further fixed inside the housing 11. The lead - screw slide 12 is composed of a lead screw, a lead - screw nut, a slide, and a pair of linear guide rails, which are common technical means for those skilled in the art. Specifically, the lead screw is fixedly connected to the motor shaft end through a coupling, and the other end of the lead screw is radially fixed through 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 lead screw, which are fixed on the inner walls on both sides of the housing 11 and are symmetrically distributed. The lead - screw nut is matched with the lead screw, the center of the slide is fixed and sleeved on the lead - screw nut, and both sides of the slide are sleeved on the two straight rods through linear bearings. When the motor rotates, it can drive the slide to reciprocate along the axis direction of the lead screw.

[0052] As an alternative embodiment, the lead - screw slide 12 adopts a lead - screw pair with a lead of 1 mm. When the effective stroke of the lead - screw nut is 60 mm, under the drive of the motor, the traveling speed of the lead - screw nut is 10 mm / s, and it takes about 6 s to complete a one - way movement. Since the length of the body of the rinsing bottle 4 (excluding the threaded mouth) is about 70 mm, and the length after compression is about 10 mm, that is, the effective compression distance of the rinsing bottle 4 is about 60 mm, which is also the effective stroke of the lead - screw nut.

[0053] Preferably, a supporting seat 13 is also fixed on the surface of the sliding table. The supporting seat 13 is plate-shaped, and its two sides extend towards the linear guide rail. At least a pair of symmetric and through adjusting grooves 131 are formed on the two side surfaces of the supporting seat 13, and a pressing rod 132 can pass through the adjusting grooves 131, and the pressing rod 132 can be fixed at any position of the adjusting grooves 131. The surface of the supporting seat 13 is used to bear the bottom position of the flushing bottle 4, and the two symmetrically distributed pressing rods 132 can clamp the corrugated grooves on the flushing bottle 4. When the lead screw nut moves, the supporting seat 13 can be driven by the sliding table to move linearly, and then the flushing bottle 4 can be compressed and stretched through the pressing rods 132, so as to control the inflow and outflow of the liquid inside the flushing bottle 4.

[0054] As a preferred embodiment, a gasket conforming to the radian of the flushing bottle 4 is also provided at the position where the surface of the supporting seat 13 contacts the flushing bottle 4, and at the bottom position of the flushing bottle 4, a push plate is fixed on the surface of the supporting seat 13, which can ensure the effectiveness of the compression force and the force application position when the flushing bottle 4 is compressed.

[0055] As a preferred embodiment, the pressing rod 132 is selected as a full-thread screw rod, and two nuts are installed on both sides of the notch of the adjusting groove 131 to fix the pressing rod 132. In addition, the contact friction between the pressing rod 132 and the flushing bottle 4 can be increased.

[0056] Preferably, a supporting bracket 14 is also fixed in the axial direction of the housing 11. When the flushing bottle 4 is placed inside through the placing opening 112 provided on the side wall of the housing 11 and the bottom of the flushing bottle 4 fits the surface of the above-mentioned push plate, the supporting bracket 14 is located at the connection between the threaded opening and the bottle body of the flushing bottle 4. Both ends of the supporting bracket 14 are fixedly connected to the inner wall of the housing 11. A through moving groove 141 is also formed on the surface of the supporting bracket 14, and the retaining pieces 142 are fixed on the supporting bracket 14 along the vertical direction through conventional bolts and nuts, and the positions of the two retaining pieces 142 are controlled by moving the conventional bolts and nuts in the moving groove 141. The retaining pieces 142 and the supporting bracket 14 form a semi-surrounding structure for clamping the connection between the threaded opening and the bottle body of the flushing bottle 4.

[0057] Preferably, the infusion assembly 15 is directly placed inside the housing 11, at the position between the supporting 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 three-way pipe 152 is also fixed on the outer end surface of the sealing cap 151 and is communicated with each other. Two check valves 153 are also fixed and communicated on the remaining two pipes of the three-way pipe 152. The communication directions of the two check valves 153 are opposite. In addition, hoses 154 are respectively fixed at the other ends of the two check valves 153.

[0058] 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, 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 the pressure rod 132, only one check valve 153 can perform the discharge action, and the corresponding hose 154 here is used for liquid supply.

[0059] 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.

[0060] As an optional implementation, the three-way pipe 152 and the check valve 153 can be replaced by a three-way valve. One of the valve ports of the three-way valve is fixedly connected and communicated 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, so when suction and discharge actions are required, the connection paths of the two routes need to be switched specifically.

[0061] 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 a switch.

[0062] Preferably, the support end 21 is a prism or truncated cone shell structure, with two ends connected, and two symmetrical parallel plates 211 are fixed on both sides of the opening at the top of the support end 21, and the extension direction of the parallel plates 211 intersects with the axis direction of the housing 11 and is approximately perpendicular. Two pairs of symmetrically distributed shaft seats 212 are fixed on the two opposite surfaces of the two parallel plates 211, and the parallel optical axis 22 is installed on each pair of shaft seats 212.

[0063] Preferably, a long keyway 221 running through the head and tail is provided on the side wall of the parallel optical axis 22, a prism 222 is fixed at the end of the parallel optical axis 22, and a limiting plate 223 is fixed at the connection between the two, so when the parallel optical axis 22 passes through any pair of shaft seats 212, it can be positioned by the limiting plate 223, and the fixing block 224 is installed on the other surface of the limiting plate 223, can be passed through by the parallel optical axis 22, and is fixed on the parallel plate 211, and is used to limit the axial direction of the parallel optical axis 22. It should be noted that both parallel optical axes 22 can rotate in the circumferential direction after being limited.

[0064] As a preferred embodiment, the prism 222 is in the shape of a quadrangular prism or a hexagonal prism.

[0065] Preferably, the linear slider 23 is fixed with guide arms 231 distributed at four corners on its surface, a total of two pairs, which can be sleeved on the outer walls of two parallel optical axes 22 respectively. Therefore, the linear slider 23 can reciprocate along the axial direction of the parallel optical axes 22.

[0066] An activity shaft 233 penetrates and is sleeved at the central position of the linear slider 23. A positioning piece 232 is further provided at one end of the activity shaft 233 away from the linear slider 23. The positioning piece 232 is used for limiting the axial direction of one side of the linear slider 23, but does not affect the circumferential rotation of the activity shaft 233. The positioning piece 232 is fixed on the surface of the linear slider 23 by conventional bolts.

[0067] In addition, an arc-shaped block 234 is further fixed on the outer surface of the linear slider 23. The surface of the arc-shaped block 234 is used for guiding, and a through groove 235 is also provided on the arc-shaped block 234.

[0068] Preferably, a worm gear 241 and a gear 242 are respectively fixed on the activity shaft 233. The gear 242 is close to the positioning piece 232, and the worm gear 241 is close to the inner surface of the linear slider 23 on one side. The rack 243 can be fixed on any one of the parallel plates 211 and is located inside the parallel plate 211. The tooth surface of the rack 243 faces the gear 242, and the two are meshed. The worm 244 can be sleeved on any one of the parallel optical axes 22 and is located between two guide arms 231 in a concentric position. Constrained by the axial direction of the guide arms 231, it can be meshed with the worm gear 241.

[0069] It should be noted that a fastening bolt 2441 is installed inside the side wall of the worm 244 for fixing the worm 244 on the parallel optical axis 22. Different from the traditional use method, there needs to be a gap between the bottom of the fastening bolt 2441 and the surface of the long key groove 221. That is, when there is no constraint of the linear slider 23, the rotation of the parallel optical axis 22 can drive the worm 244 to rotate synchronously. At this time, the worm 244 can also move axially along the parallel optical axis 22.

[0070] When the parallel optical axis 22 installed with the worm 244 rotates, it can drive the worm 244, thereby driving the worm gear 241 to rotate. The worm gear 241 drives the gear 242 to rotate through the activity shaft 233, and then moves through the meshing of the gear 242 and the rack 243, thereby driving the entire linear slider 23 to move axially on the two parallel optical axes 22. Finally, the worm 244 also moves in the same direction because it is in the middle of the two guide arms 231.

[0071] As a preferred embodiment, the parameters selected for the worm gear 241 and the worm 244 are a module of 0.5 and a speed ratio of 20. That is, when the rotation speed of the parallel optical axis 22 is the same as that of the motor, the rotation speed of the worm gear 241 is 30 r / min, and the gear 242 is also at the same speed.

[0072] 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.

[0073] 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 left to continue flushing the vulva.

[0074] Preferably, the flexible shaft core 27 is a flexible power transmission member, one end of which is fixedly connected to the tail of the lead screw through a coupling, and the other end is plugged into the prism 222 on the parallel optical axis 22 through a joint 271, so the joint 271 is fixedly connected to the other end of the flexible shaft core 27, and a prism hole with the same shape as the prism 222 is reserved on the surface of the joint 271. Therefore, when the lead screw rotates, it can synchronously drive the parallel optical axis 22 to rotate through the flexible shaft core 27.

[0075] 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.

[0076] 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.

[0077] The cross section of the open slot 2511 is circular, and its opening on the surface of the adjustable swing arm 251 is narrower than the slot body. The moving column 2513 is adapted to the shape of the slot body and is sleeved on the stud part of the adjusting bolt 2512. The two are threadedly matched, and the column head part of the moving column 2513 extends out of the opening on the surface of the adjustable swing arm 251. When the adjusting bolt 2512 is rotated, the moving column 2513 can be moved along the axial direction of the opening, so that the position of the moving column 2513 can be adjusted.

[0078] Preferably, an oscillating arm 2521 is fixed to one side of the oscillating seat 252, and the two are perpendicular to each other. A waist-shaped hole 2522 is formed through the oscillating arm 2521. An arc-shaped block 2523 is fixed at the connection between the oscillating arm 2521 and the oscillating seat 252, and the bottom of which can fit with the arc surface of the inner wall of the arc-shaped block 234. The oscillating arm 2521 can pass through the through groove 235. At this time, the head of the moving 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 arc-shaped limiting piece 2526 is fixed on the side wall of the arc-shaped block 2523, and the arc surface of the arc-shaped limiting piece 2526 fits with the arc surface of the outer wall of the arc-shaped block 234, which is used for limiting the oscillating seat 252 along the axial direction of the oscillating arm 2521.

[0079] Preferably, the connecting ring 26 is fixed to the surface of the oscillating seat 252 facing away from the movable shaft 233. A nozzle 2525 is also fixed at the center of the connecting ring 26. A connecting pipe 2524 is fixed at the center of the surface facing the movable shaft 233. The connecting pipe 2524 is communicated with the nozzle 2525. The other end of the hose 154 for discharging liquid is communicated with and fixed to the connecting pipe 2524.

[0080] The connecting ring 26 is used for threaded connection with the flushing pipe 5.

[0081] Refer to Figure 13 , when the adjustable oscillating arm 251 rotates, the head part of the moving column 2513 can drive the oscillating arm 2521 to move. Correspondingly, the oscillating seat 252 will swing reciprocally with the center O and along the track of the arc-shaped block 234. At this time, the flushing pipe 5 will reciprocally move within the swing width D.

[0082] It should be noted that the vaginal width has significant elasticity, and the normal range varies according to the physiological state. The vaginal width of non-childbearing women is about 1.5 - 2.5 cm, while that of childbearing women is 2.5 - 4 cm. Therefore, D3 is set as the maximum swing width, about 40 mm, D2 is set as 30 mm, and D1 is set as 20 mm. The swing range D depends on the position of the moving column 2513 on the adjustable oscillating arm 251, that is, depends on the size of the track C when the moving column 2513 makes a circular motion. The track C3 corresponds to the swing width of D3, C2 corresponds to D2, and C1 corresponds to D1.

[0083] Scale grooves are formed on the two side walls of the adjustable oscillating arm 251. The scale grooves respectively correspond to the three positions where the center of the moving column 2513 is located, that is, the positions when the flushing pipe 5 swings 40 mm, 30 mm, and 20 mm, for reference. Due to differences among individuals, it is necessary to manually adjust the adjusting bolt 2512 to control the moving column 2513 to a position that suits one's own conditions to reduce discomfort.

[0084] As a preferred embodiment, the trajectory of the maximum radius when the moving column 2513 makes a circular motion is restricted to trajectory C3, that is, no matter how it is adjusted, it will not exceed C3.

[0085] It should be noted that the vaginal irrigation device involved in the present invention can achieve three modes: When irrigating the vulva, it is necessary to disconnect the connection between the flexible shaft center 27 and the parallel optical axis 22. At this time, the irrigation tube 5 is not installed, and the swing seat 252 does not deflect. At this time, the irrigation bottle 4 is filled by suction, and then the irrigation bottle 4 is compressed by the lead 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 to automatically irrigate.

[0086] During traditional irrigation, it is necessary to disconnect the connection between the flexible shaft center 27 and the parallel optical axis 22. At this time, the irrigation tube 5 is installed, and the swing seat 252 does not deflect. At this time, the irrigation bottle 4 is filled by suction, and then the irrigation tube 5 is inserted into the vagina. Then, the irrigation bottle 4 is compressed by the lead screw slide 12. The liquid in the bottle is sent into the irrigation tube 5 through the hose 154 and the nozzle 2525, and the liquid can be discharged through the holes at the end of the irrigation tube 5, so as to achieve the irrigation of the vagina.

[0087] During all-round irrigation, first, the irrigation bottle 4 is filled by suction, and then the flexible shaft center 27 and the parallel optical axis 22 are connected. At this time, the irrigation tube 5 is installed, and the swing seat 252 does not deflect. At this time, the irrigation tube 5 is inserted into the vagina, and then the irrigation bottle 4 is compressed by the lead screw slide 12. The liquid in the bottle is sent into the irrigation tube 5 through the hose 154 and the nozzle 2525. At the same time, the irrigation tube 5 will reciprocate according to the preset swing width and gradually withdraw from the vagina, so as to achieve all-round irrigation of the vagina.

[0088] In summary, by combining with a straight - head extrusion - type irrigator, the present invention significantly improves the clinical effect and operational convenience. The liquid storage unit realizes a pulling and pushing suction mechanism through the easily compressible feature of the straight - head extrusion - type irrigator in cooperation with a check valve, which respectively solves the problems of difficult liquid perfusion and easy overflow of traditional devices, and also ensures the stability of the liquid flow rate during the irrigation process, enhancing the impact effect on secretions. The three - mode design of the irrigation unit adapts to various clinical scenarios. The irrigation path from the inside out and from top to bottom and the swing mechanism with adjustable amplitude fit well with the characteristics of vaginal anatomy. Since the head of the irrigation tube is closer to the radial mucosa of the vagina and the overall contact area is larger, at the same liquid output pressure, the irrigation force is stronger and it can comprehensively flush and remove the secretions between the transverse folds. In addition, the device adopts a modular structure, which can support the compatible application of traditional irrigation bottles and irrigation tubes. It can be treated as a disposable consumable, eliminating the need for cleaning, and has a check function to isolate the liquid inside and outside the bottle, avoiding internal contamination of the bottle for multiple uses, reducing the use cost and the risk of cross - infection. For those who need step - by - step irrigation, such as critically ill patients, the rapid liquid replacement effect of this device significantly improves the operation and treatment efficiency. In addition, the adjustable swing amplitude of the irrigation tube can adjust the cleaning plan according to individual patient differences, reducing the discomfort during the treatment process and improving patient compliance.

[0089] The simple - operation characteristic of this device not only reduces the operation burden of medical staff, but also enables patients to easily master the usage method in a home environment, expanding the application scenarios of the device. By integrating the liquid storage unit and the irrigation unit, stable liquid supply, automatic irrigation path control, multi - mode application scenario adaptation, and low - cost consumable replacement are achieved, significantly improving the effectiveness, convenience, and safety of vaginal irrigation.

[0090] Therefore, the present invention has comprehensive technical advantages in improving the irrigation effect, simplifying the operation process, reducing the use cost, and enhancing adaptability.

[0091] Importantly, the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
