Description

Technical Field

[0001] This invention relates to the field of medical devices, and more specifically, to an intelligent sterilizer for gynecological care. Background Technology

[0002] Gynecology is a medical specialty department that specializes in treating gynecological diseases. There are many types of gynecological diseases, common ones include: uterine fibroids, ovarian cysts, vaginitis, cervicitis, cervical erosion, pelvic inflammatory disease, adnexitis, dysfunctional uterine bleeding, breast diseases, infertility, menstrual disorders, endometritis, and abnormal vaginal discharge. Regular disinfection and care are necessary during the treatment of gynecological diseases to facilitate a faster recovery.

[0003] In actual use, because the disinfection tube has a certain diameter, direct insertion can easily cause discomfort to the patient and is also inconvenient, which is not conducive to the patient's recovery treatment.

[0004] To address the aforementioned technical issues, Chinese Patent Application No. CN115591092A discloses a user-friendly gynecological care sterilizer. This sterilizer uses two arc-shaped expansion plates that are far apart to open the patient's vagina, facilitating the placement of the drainage tube and subsequent sterilization procedures. This reduces discomfort during insertion and makes observation easier, allowing for better identification and sterilization of lesions. However, when the drainage tube is inserted into the vagina, its surface rubs against the vaginal mucosa, causing abrasions and minor damage, leading to stinging, burning, and a feeling of heaviness. In severe cases, it can even cause minor contact bleeding. Summary of the Invention

[0005] In view of the problems existing in the prior art, the purpose of this invention is to provide an intelligent sterilizer for gynecological care.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A smart sterilizer for gynecological care includes a grip, a limiting rod fixedly connected to the outer surface of the grip near the top, a slide plate slidably connected to the outer surface of the limiting rod, a control panel fixedly connected to one side of the slide plate, a fixing block fixedly connected to the bottom of the slide plate, a pressing rod fixedly connected to the bottom of the fixing block, a connecting assembly fixedly connected to the top of the slide plate, an injection tube disposed inside the connecting assembly, an outlet hole opened at the end of the injection tube, a piston cylinder disposed on one side of the injection tube, a piston rod slidably disposed inside the piston cylinder, and a lubrication assembly for lubricating the surface of the injection tube disposed on the top of the grip.

[0008] The lubrication assembly includes a storage chamber fixed to the top of the gripping part. Multiple discharge ports are evenly distributed on one side of the storage chamber. A piston plate is slidably connected inside the storage chamber. A push rod is symmetrically fixed to one side of the piston plate. A release component is provided on the top of the push rod away from the piston plate. A filling port is provided on the outer surface of the storage chamber near the discharge port. A metering component is provided on the outer surface of the storage chamber away from the filling port.

[0009] Furthermore, the connecting assembly includes a connecting ring fixed to the top of the slide plate, with U-shaped plates symmetrically fixedly connected to the inner surface of the connecting ring, a magnet fixedly connected to the top of the U-shaped plates, and a metal plate inserted inside the U-shaped plates. The sides of the two metal plates that are close to each other are fixedly connected to the outer surface of the injection tube.

[0010] Furthermore, the injection tube penetrates the interior of the storage chamber, and the injection tube and the storage chamber slide and adapt to each other. A heating rod is fixedly connected to the middle of the injection tube. The control panel is connected to the heating rod via an electrical signal. A drug injection port is provided on the outer surface of the piston cylinder near the injection tube.

[0011] Furthermore, a support is fixedly connected to one edge of the storage compartment, and a through groove is opened in the middle of the inside of the support, and the injection tube is adapted to the through groove.

[0012] Furthermore, the release assembly includes two fixing plates symmetrically fixed to one side of the connecting ring and a triangular block fixed to the top of the push rod away from the piston plate. A trapezoidal rod is slidably connected inside the fixing plates, and a first spring is fixedly connected to one side of the trapezoidal rod.

[0013] Furthermore, the inclined surface of the trapezoidal rod is arranged opposite to the inclined surface of the triangular block, and the inclined surface of the trapezoidal rod and the inclined surface of the triangular block slide against each other, and one end of the first spring is fixedly connected to the fixing plate.

[0014] Furthermore, the metering component includes a vertical rod fixed to the outer surface of the storage compartment and a metering groove opened inside the push rod. A second spring is sleeved on the outer surface of the vertical rod, and a clamping plate is slidably connected to the bottom of the outer surface of the vertical rod.

[0015] Furthermore, the card plate is L-shaped, with its bottom extending into the interior of the metering groove and configured to slide axially within the metering groove. A limiting plate is fixedly connected to the top of the vertical rod, and the second spring is located above the card plate.

[0016] Furthermore, the outer surface of the grip is provided with a limiting component for limiting and fixing the injection tube. The limiting component includes two mounting rods fixed to the outer surface of the grip and a locking block fixed to both sides of the fixing block. A third spring is fixedly connected to the side of the two mounting rods that are far apart from each other. A paddle is fixedly connected to the side of the two third springs that are far apart from each other. Two telescopic rods are fixedly connected to one side of the paddle. A ratchet rack is fixedly connected to one side of the two telescopic rods.

[0017] Furthermore, the locking block is located between two serrated racks, the serrated racks and the locking block mesh with each other, the telescopic rod and the mounting rod slide against each other, and the teeth of the locking block and the serrated racks are both right-angled trapezoids.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. This solution incorporates a lubrication component. When the injection tube moves, it drives the push rod to move synchronously, causing the piston plate to push the lubricant inside the reservoir. This forces the lubricant to fall onto the surface of the moving injection tube through the outlet, thus lubricating the surface of the injection tube. After lubrication, a liquid film is formed between the injection tube and the vaginal wall, avoiding dry friction and reducing mucosal abrasion, stinging, and bleeding. Insertion is smoother, without dryness, jamming, or foreign body pain, improving the user experience of the device.

[0020] 2. This solution uses a release component to trigger the trapezoidal rod to slide on the inclined surface of the triangular block when the thrust reaches a certain value, forcing the trapezoidal rod to move upward as a whole until it passes through the triangular block, thus not obstructing the normal movement of the injection tube.

[0021] 3. This solution uses a metering component to insert a card plate into the metering tank. The card plate slides relative to the metering tank. When the card plate moves to the other end of the metering tank, the push rod can no longer move. This effectively controls the displacement distance of the piston plate inside the reservoir, controls the amount of lubricant discharged onto the surface of the injection tube, avoids excessive lubricant forming a separating film, prevents interference with drug contact with the mucous membrane, and reduces lubricant waste.

[0040] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0041] Please see Figures 1 to 8A smart sterilizer for gynecological care includes a grip 1. A limiting rod 13 is fixedly connected to the outer surface of the grip 1 near the top. A slide plate 12 is slidably connected to the outer surface of the limiting rod 13. A control panel 10 is fixedly connected to one side of the slide plate 12. A fixing block 14 is fixedly connected to the bottom of the slide plate 12. A pressing rod 11 is fixedly connected to the bottom of the fixing block 14. A connecting assembly 9 is fixedly connected to the top of the slide plate 12. A drug injection tube 5 is provided inside the connecting assembly 9. An outlet hole 16 is opened at the end of the drug injection tube 5. A piston cylinder 6 is provided on one side of the drug injection tube 5. A piston rod 7 is slidably arranged inside the piston cylinder 6. A lubrication assembly 4 for lubricating the surface of the drug injection tube 5 is provided on the top of the grip 1.

[0042] like Figures 2-3 As shown, the lubrication assembly 4 includes a storage chamber 41 fixed to the top of the gripping part 1. Multiple discharge ports 42 are evenly opened on one side of the storage chamber 41. A piston plate 46 is slidably connected inside the storage chamber 41. A push rod 43 is symmetrically fixed to one side of the piston plate 46. A release assembly 44 is provided on the top of the push rod 43 away from the piston plate 46. A filling port 47 is provided on the outer surface of the storage chamber 41 near the discharge port 42. A metering assembly 45 is provided on the outer surface of the storage chamber 41 away from the filling port 47.

[0043] The connecting component 9 includes a connecting ring 91 fixed to the top of the slide plate 12. A U-shaped plate 92 is symmetrically fixed to the inner surface of the connecting ring 91. A magnet 94 is fixedly fixed to the top of the U-shaped plate 92. A metal plate 93 is inserted inside the U-shaped plate 92. The side of the two metal plates 93 that are close to each other is fixedly connected to the outer surface of the injection tube 5.

[0044] The injection tube 5 passes through the interior of the storage chamber 41. The injection tube 5 and the storage chamber 41 slide and adapt to each other. A heating rod 15 is fixedly connected to the middle of the inside of the injection tube 5. The control panel 10 is connected to the heating rod 15 via an electrical signal. A drug injection port is provided on the outer surface of the piston cylinder 6 near the injection tube 5.

[0045] A support part 2 is fixedly connected to one side edge of the storage compartment 41. A through groove 3 is opened in the middle of the inside of the support part 2. The injection tube 5 is adapted to the through groove 3.

[0046] When using the sterilizer, the patient adds medication into the piston cylinder 6 through the medication inlet. The medication fills the injection tube 5 and the piston cylinder 6. The heating rod 15 is then powered on via the control panel 10 to heat the medication inside the injection tube 5 and piston cylinder 6. The control panel 10 is used to preset the temperature of the heated medication. Once ready, the support part 2 is placed against the patient's vagina, aligning the through groove 3 with the vaginal opening. At this point, the pressing rod 11 is pushed, causing the sliding plate 12 and connecting ring 91 to move. Through the transmission between the U-shaped plate 92 and the metal plate 93, the injection tube 5 is simultaneously moved towards the through groove 3. When the groove 3 moves, the connecting ring 91 drives the push rod 43 to move through the release component 44, which in turn drives the piston plate 46 to move to one side inside the storage chamber 41. The piston plate 46 pushes the lubricant inside the storage chamber 41 out of the discharge port 42. The lubricant falls onto the surface of the moving injection tube 5 through the discharge port 42, lubricating the surface of the injection tube 5. After lubrication, a liquid film is formed between the injection tube 5 and the vaginal wall, avoiding dry friction, reducing mucosal abrasion, stinging, and bleeding, making insertion smoother, without dryness, jamming, or foreign body pain, and improving the user experience of the device.

[0047] like Figure 4 As shown, the release assembly 44 includes two fixing plates 441 that are axially symmetrically fixed to one side of the connecting ring 91 and a triangular block 443 fixed to the top of the push rod 43 on the side away from the piston plate 46. A trapezoidal rod 442 is slidably connected inside the fixing plate 441, and a first spring 444 is fixedly connected to one side of the trapezoidal rod 442.

[0048] The inclined surface of the trapezoidal rod 442 is set opposite to the inclined surface of the triangular block 443, and the inclined surface of the trapezoidal rod 442 and the inclined surface of the triangular block 443 slide against each other. One end of the first spring 444 is fixedly connected to the fixing plate 441.

[0049] When the injection tube 5 is pushed to move synchronously, it will cause the piston plate 46 to move inside the storage chamber 41. When the piston plate 46 moves to the end of the storage chamber 41, the piston plate 46 can no longer move, which will also prevent the injection tube 5 from moving to the lesion in the vagina. Therefore, when the piston plate 46 moves to the end, continue to press the pressing rod 11 towards the grip part 1. The pressing rod 11 will cause the trapezoidal rod 442 and the triangular block 443 to come into contact and squeeze each other through the slide plate 12 and the connecting ring 91. When the pressing rod 11 is pushed against the triangular block 443, the pressure will be applied upwards. When the component force is greater than the deformation force of the first spring 444, the trapezoidal rod 442 will slide on the inclined surface of the triangular block 443, forcing the trapezoidal rod 442 to move upward as a whole until the trapezoidal rod 442 passes through the triangular block 443. At this time, the connecting ring 91 will drive the injection tube 5 to continue moving through the U-shaped plate 92 and the metal plate 93, thereby ensuring that the normal movement of the injection tube 5 will not be hindered. Through the cooperation of the trapezoidal rod 442 and the triangular block 443, when the thrust reaches a certain value, the action of the trapezoidal rod 442 relative to the triangular block 443 will be triggered, ensuring that the injection tube 5 continues to move.

[0050] like Figure 5 As shown, the metering component 45 includes a vertical rod 453 fixed to the outer surface of the storage chamber 41 and a metering groove 451 opened inside the push rod 43. A second spring 454 is sleeved on the outer surface of the vertical rod 453, and a clamping plate 452 is slidably connected to the bottom of the outer surface of the vertical rod 453.

[0051] The clamping plate 452 is L-shaped, and the bottom of the clamping plate 452 extends into the interior of the metering groove 451 and is configured to slide axially within the metering groove 451. The top of the vertical rod 453 is fixedly connected to a limiting plate, and the second spring 454 is located above the clamping plate 452.

[0052] During the movement of the injection tube 5, not only can lubricant be added automatically, but the engagement of various components can also be disengaged by the release assembly 44 to prevent the push rod 43 and piston plate 46 from obstructing the movement of the injection tube 5. However, the amount of lubricant added inside the storage chamber 41 should be controlled to a certain level: if too much lubricant is added, a thick layer of lubricant on the surface of the injection tube 5 will form a barrier film, preventing ozone and disinfectant from fully contacting the mucous membrane. Therefore, before adding lubricant, the clamping plate 452 is inserted into the metering tank 451. During the movement of the injection tube 5, the release assembly 44 pushes the push rod 43 into the storage chamber 41, while the clamping plate 452 slides relative to the metering tank 451. When the clamping plate 452 moves to the other end of the metering tank 451, the push rod 43 can no longer move, thereby effectively controlling the displacement distance of the piston plate 46 inside the storage chamber 41, controlling the amount of lubricant sprayed on the surface of the injection tube 5, preventing excessive lubricant from forming a barrier film, avoiding affecting the contact between the drug and the mucous membrane, and reducing lubricant waste.

[0053] like Figures 7-8 As shown, a limiting component 8 for limiting and fixing the injection tube 5 is provided on the outer surface of the grip 1. The limiting component 8 includes two mounting rods 81 fixed on the outer surface of the grip 1 and a locking block 86 fixed on both sides of the fixing block 14. A third spring 82 is fixedly connected to the side of the two mounting rods 81 that is far apart from each other. A paddle 84 is fixedly connected to the side of the two third springs 82 that is far apart from each other. Two telescopic rods 83 are fixedly connected to one side of the paddle 84. A ratchet rack 85 is fixedly connected to one side of the two telescopic rods 83.

[0054] The locking block 86 is located between the two ratchet racks 85. The ratchet racks 85 and the locking block 86 mesh with each other, and the telescopic rod 83 and the mounting rod 81 slide against each other. The teeth of the locking block 86 and the ratchet racks 85 are both right-angled trapezoids.

[0055] When the injection tube 5 is inserted into the vagina, to prevent it from slipping out during injection, the pressing rod 11 simultaneously moves the locking block 86 between the two thorny racks 85. The inclined surfaces of the teeth on the thorny racks 85 and the inclined surfaces of the locking block 86 slide against each other. Each time the locking block 86 passes a tooth on the thorny rack 85, the third spring 82 quickly engages the thorny rack 85 and the locking block 86 through its elastic force, ensuring that the locking block 86 can only move towards the gripping part 1 and cannot move in the opposite direction, thus preventing the injection tube 5 from slipping out of the vagina. When the injection tube 5 reaches the designated position, the piston rod 7 pushes the piston cylinder 6 to spray the liquid inside through the outlet hole 16. The liquid comes into contact with the lesion for disinfection treatment, preventing the injection tube 5 from slipping out during disinfection and causing unnecessary trouble.

[0056] Instructions for use: When using the sterilizer, the patient adds medication into the piston cylinder 6 through the medication inlet. The medication fills the injection tube 5 and the piston cylinder 6. The heating rod 15 is then powered on via the control panel 10 to heat the medication inside the injection tube 5 and the piston cylinder 6. The temperature of the heated medication is preset via the control panel 10. After preparation, the support part 2 is placed against the patient's vagina, so that the through groove 3 is aligned with the patient's vaginal opening. At this time, the pressing rod 11 is pushed to move the sliding plate 12 and the connecting ring 91. Through the transmission between the U-shaped plate 92 and the metal plate 93, the injection tube 5 moves synchronously towards the through groove 3. During the movement, the connecting ring 91 drives the push rod 43 to move through the release component 44, driving the piston plate 46 to move to one side inside the storage chamber 41. The piston plate 46 pushes the lubricant inside the storage chamber 41 out from the discharge port 42. The lubricant falls onto the surface of the moving injection tube 5 through the discharge port 42, lubricating the surface of the injection tube 5.

[0057] Insert the card plate 452 into the metering groove 451. During the movement of the injection tube 5, the release component 44 pushes the push rod 43 to move into the storage chamber 41. At the same time, the card plate 452 slides relative to the inside of the metering groove 451. When the card plate 452 moves to the other end of the metering groove 451, the push rod 43 can no longer move, thereby effectively controlling the displacement distance of the piston plate 46 inside the storage chamber 41 and controlling the amount of lubricant sprayed on the surface of the injection tube 5. By setting the release component 44, the smooth movement of the injection tube 5 can be guaranteed.

[0058] After use, the injection tube 5 can be rotated, which will cause the two metal plates 93 to move in a circular motion. The metal plates 93 will move out of the U-shaped plate 92, so that the metal plates 93 and the magnet 94 will no longer be attracted and fixed. At this time, the injection tube 5 can be pulled out from the inside of the connecting ring 91, and the piston rod 7 can be pulled out from the inside of the piston cylinder 6 to clean the inside of the injection tube 5 and the piston cylinder 6, which greatly improves the cleaning efficiency.

[0059] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
