Description

Technical Field

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

[0002] Cervical cancer is the most common malignant tumor of the female reproductive tract. Failure to perform regular vaginal dilation and irrigation after cervical cancer treatment can lead to complications such as vaginal adhesions, stenosis, and fibrosis. Therefore, vaginal douches are used clinically to dilate and irrigate the vagina of patients undergoing radiotherapy and chemotherapy.

[0003] Existing vaginal douches need to be inserted into the vagina and contact the vaginal wall to open it during the douche process. The part of the vaginal douche that contacts the vagina is difficult to rinse, resulting in incomplete vaginal rinsing and poor rinsing effect. Summary of the Invention

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] Some embodiments of this application propose a vaginal irrigation device and irrigation method to solve the technical problems mentioned in the background section above.

[0006] As a first aspect of this application, some embodiments of this application provide a vaginal irrigation device, including a support for forming the outer contour of the vaginal irrigation device, the support having a locking component; a first irrigation component disposed on the support; a second irrigation component cooperating with the first irrigation component to irrigate the vaginal wall; and further including: a switching component disposed on the support and acting on the first and second irrigation components to cause the first and second irrigation components to alternately irrigate the vaginal wall.

[0007] Furthermore, the first flushing assembly includes a first chamber and a first abutting assembly. The first chamber is provided with a first piston rod that divides the first chamber into a first sub-chamber and a second sub-chamber. One end of the first piston rod is fixedly connected to the first abutting assembly. The end of the first chamber away from the first abutting assembly is connected to the switching assembly.

[0008] Furthermore, the second flushing assembly includes a second chamber and a second abutment assembly. The second chamber is provided with a second piston rod that divides the second chamber into a third sub-chamber and a fourth sub-chamber. One end of the second piston rod is fixedly connected to the second abutment assembly. The end of the second chamber away from the second abutment assembly is connected to the switching assembly.

[0009] Furthermore, the switching assembly includes a first push rod and a first channel, the first push rod extending into the first channel, the first channel being filled with hydraulic oil, and the first channel connecting the first sub-cavity and the fourth sub-cavity.

[0010] Furthermore, the switching assembly also includes a second push rod and a second channel. The second push rod extends into the second channel, which is filled with hydraulic oil. The second channel connects the second sub-cavity and the third sub-cavity, both of which are connected to an oil tank.

[0011] Furthermore, a delay component is provided in the connecting pipe between the second sub-cavity and the second channel, and a delay component is provided in the connecting pipe between the fourth sub-cavity and the first channel. The delay component includes a spring and a conical pusher. One end of the spring is connected to the inner wall of the delay component, and the other end is connected to the conical pusher. The conical pusher abuts against the oil inlet of the delay component.

[0012] Furthermore, both the first flushing component and the second flushing component are connected to a water inlet pipe and a nozzle. The first abutting component and the second abutting component are provided with several through holes at equal intervals, and each through hole is provided with a nozzle. The other end of the nozzle is connected to the water inlet pipe.

[0013] Furthermore, the nozzle is slidably connected to the inner wall of the through hole of the first abutting component and the second abutting component, and the other end of the nozzle is fixed to the flexible plate. The flexible plate is provided with an elastic plate on the side away from the nozzle, and the end of the elastic plate away from the flexible plate abuts against a protrusion provided on the bracket.

[0014] Furthermore, both the first abutting component and the second abutting component are configured in an arc shape.

[0015] As a second aspect of this application, some embodiments of this application provide a vaginal irrigation method, implemented using the aforementioned vaginal irrigation device, comprising the following steps:

[0016] Step 1: Insert the stent into the vagina and push the locking component to fix the stent in the designated locking position;

[0017] Step 2: Irrigate the vagina for time t1;

[0018] Step 3: Push the first push rod so that the first abutting component of the first flushing assembly and the second abutting component of the second flushing assembly are at the same height. Continue to push the first push rod until the second abutting component descends to the initial position of the first abutting component of the first flushing assembly, then stop pushing the first push rod.

[0019] Step 4: Open the valve of the water inlet pipe for time t2;

[0020] Step 5: Push the second push rod so that the second abutting component of the second flushing assembly and the first abutting component of the first flushing assembly are at the same height. Continue to push the second push rod until the first abutting component descends to the position where the second abutting component of the second flushing assembly was last in Step 3, then stop pushing the second push rod.

[0021] Step 6: After holding the valve on the inlet pipe for time t3, close the valve.

[0022] Step 7: Unlock the locking component and move the bracket to remove the vaginal irrigation device.

[0023] Compared with the prior art, the technical solution provided by this invention has the following advantages:

[0024] This invention improves the flushing effect by alternating the flushing of the vaginal wall with a first flushing component and a second flushing component, ensuring thorough flushing of the vaginal wall. Furthermore, by incorporating delay components in both the first and second flushing components, the first and second abutment components do not move simultaneously, reducing patient pain during the alternating flushing process.

[0046] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0047] like Figures 1 to 5 As shown, an embodiment of this application provides a vaginal irrigation device, including a support 100 for forming the outer contour of the vaginal irrigation device, the support 100 having a locking component 110; a first irrigation component 200 disposed on the support 100; a second irrigation component 300 cooperating with the first irrigation component 200 to irrigate the vaginal wall; and further including a switching component 400 disposed on the support 100 and acting on the first irrigation component 200 and the second irrigation component 300 to allow the first irrigation component 200 and the second irrigation component 300 to alternately irrigate the vaginal wall.

[0048] Specifically, the support 100 includes a handle 120, a fixed part 130, and a movable part 140. The support 100 is an irregular cylinder, facilitating insertion into the patient's vagina. The handle 120 of the support 100 is used by the operator to hold the entire vaginal irrigation device. One end of the handle 120 is connected to the fixed part 130, and the fixed part 130 and the handle 120 cannot move relative to each other. The movable part 140 is movably connected to the handle 120, and the movable part 140 can move relative to the handle 120 to allow the entire vaginal irrigation device to open a certain distance, i.e., the opening and closing distance between the movable part 140 and the fixed part 130, to accommodate different patients. A locking component 110 is provided in the groove of the movable part 140. In one specific embodiment, the locking component 110 is a knob. When the knob is rotated, friction prevents relative displacement between the movable part 140 and the handle 120.

[0049] The vaginal irrigation device includes a first irrigation component 200 and a second irrigation component 300. Both the first and second irrigation components are divided into two parts, symmetrically arranged on the fixed portion 130 and the movable portion 140 of the support 100, respectively. For ease of description, the first and second irrigation components 200 and 300 will be described using the portion on the movable portion 140. The first and second irrigation components 200 are arranged sequentially along the length of the vaginal irrigation device, with the first irrigation component 200 closer to the handle 120 and the second irrigation component 300 further away from the handle 120. The first and second irrigation components 200 can alternately irrigate the vaginal wall; that is, when the first irrigation component 200 irrigates the vaginal wall, the second irrigation component 300 provides support for the vaginal wall, and vice versa. The alternating operation of the first flushing component 200 and the second flushing component 300 is achieved by switching the switching component 400. That is, the operator can use the switching component 400 to alternately flush the vaginal wall with the first flushing component 200 and the second flushing component 300.

[0050] More specifically, the first flushing assembly 200 includes a first chamber 210 and a first abutting assembly 220. The first chamber 210 is provided with a first piston rod 213 that divides the first chamber 210 into a first sub-chamber 211 and a second sub-chamber 212. One end of the first piston rod 213 is fixedly connected to the first abutting assembly 220. The end of the first chamber 210 away from the first abutting assembly 220 is connected to the switching assembly 400.

[0051] In the first chamber 210, the first piston rod 213 supports the first abutment component 220. One end of the first abutment component 220 abuts against the vaginal wall. As the first piston rod 213 moves within the first chamber 210, its piston block divides the first chamber 210 into a first sub-cavity 211 and a second sub-cavity 212. When the first piston rod 213 controls the first abutment component 220 to move closer to the vaginal wall, the volume of the first sub-cavity 211 increases, and the volume of the second sub-cavity 212 decreases. Conversely, when the first piston rod 213 controls the first abutment component 220 to move away from the vaginal wall, the volume of the first sub-cavity 211 decreases, and the volume of the second sub-cavity 212 increases. The switching component 400 connects the first sub-cavity 211 and the second sub-cavity 212. Therefore, the switching component 400 can control whether the first abutment component 220 moves closer to or further away from the vaginal wall by controlling the volume of the first sub-cavity 211 and the second sub-cavity 212.

[0052] Similarly, the second flushing assembly 300 includes a second chamber 310 and a second abutment assembly 320. The second chamber 310 is provided with a second piston rod 313 that divides the second chamber 310 into a third sub-chamber 311 and a fourth sub-chamber 312. One end of the second piston rod 313 is fixedly connected to the second abutment assembly 320. The end of the second chamber 310 away from the second abutment assembly 320 is connected to the switching assembly 400.

[0053] In the second chamber 310, the second piston rod 313 supports the second abutment component 320. One end of the second abutment component 320 abuts against the vaginal wall. The second piston rod 313 moves within the second chamber 310, dividing it into a third sub-cavity 311 and a fourth sub-cavity 312. When the second piston rod 313 controls the second abutment component 320 to move closer to the vaginal wall, the volume of the third sub-cavity 311 increases, and the volume of the fourth sub-cavity 312 decreases. Conversely, when the second piston rod 313 controls the second abutment component 320 to move away from the vaginal wall, the volume of the third sub-cavity 311 decreases, and the volume of the fourth sub-cavity 312 increases. The switching component 400 connects the third sub-cavity 311 and the fourth sub-cavity 312; therefore, by controlling the volume of the third sub-cavity 311 and the fourth sub-cavity 312, the switching component 400 can control whether the second abutment component 320 moves closer to or further away from the vaginal wall.

[0054] In one specific embodiment, the switching assembly 400 includes a first push rod 410 and a first channel 430. The first push rod 410 extends into the first channel 430, which is filled with hydraulic oil. The first channel 430 connects the first sub-cavity 211 and the fourth sub-cavity 312. The switching assembly 400 also includes a second push rod 420 and a second channel 440. The second push rod 420 extends into the second channel 440, which is filled with hydraulic oil. The second channel 440 connects the second sub-cavity 212 and the third sub-cavity 311, both of which are connected to an oil tank.

[0055] Specifically, the switching assembly 400 includes a first push rod 410 and a second push rod 420. The first push rod 410 and the second push rod 420 are operated by an operator. The operator can push or pull the first push rod 410 to control the movement of the first abutment assembly 220 and the second abutment assembly 320; similarly, the operator can push or pull the second push rod 420 to control the movement of the first abutment assembly 220 and the second abutment assembly 320. One end of the first push rod 410 extends into a first channel 430, which is a channel located in the inner wall of the bracket 100. The first channel 430 is filled with hydraulic oil or other incompressible working fluids, such as gas, etc., without limitation. When the first push rod 410 is pushed, the hydraulic oil in the first channel 430 is propelled. Since the first channel 430 connects the first sub-cavity 211 and the fourth sub-cavity 312, the hydraulic oil pushes the first piston rod 213 in the first sub-cavity 211 and the second piston rod 313 in the fourth sub-cavity 312 to move, thereby causing the first abutment component 220 and the second abutment component 320 to move closer to and further away from the vaginal wall. Both the first abutment component 220 and the second abutment component 320 are constructed in an arc shape to prevent damage to the vagina when the vaginal irrigation device is inserted, and to reduce patient discomfort when the first abutment component 220 and the second abutment component 320 come into contact with the vaginal wall.

[0056] In one specific embodiment, a delay component 500 is provided in the connecting pipe between the second sub-cavity 212 and the second channel 440, and a delay component 500 is provided in the connecting pipe between the fourth sub-cavity 312 and the first channel 430. The delay component 500 includes a spring 510 and a conical pusher 520. One end of the spring 510 is connected to the inner wall of the delay component 500, and the other end is connected to the conical pusher 520. The conical pusher 520 abuts against the oil inlet of the delay component 500.

[0057] Specifically, the delay component 500 is a chamber located in the connecting pipe between the second sub-cavity 212 and the second channel 440, and in the connecting pipe between the fourth sub-cavity 312 and the first channel 430. The chamber is equipped with a spring 510 and a conical pusher 520. One end of the spring 510 is connected to the inner wall of the chamber, and the other end of the spring 510 abuts against the conical pusher 520. The conical surface of the conical pusher 520 abuts against the oil inlet of the delay component 500. Only when the force applied to the conical surface of the conical pusher 520 is greater than the elastic force of the spring 510 can the conical pusher 520 be pushed open, and the second sub-cavity 212 and the second channel 440 can be connected. Similarly, only when the force applied to the conical surface of the conical pusher 520 is greater than the elastic force of the spring 510 can the conical pusher 520 be pushed open, and the fourth sub-cavity 312 and the first channel 430 can be connected.

[0058] The working process of the first flushing assembly 200 and the second flushing assembly 300 is as follows: When both the first push rod 410 and the second push rod 420 are in their original positions, the first abutment assembly 220 is located as follows: Figure 1 At the indicated location, a certain gap is provided between the first abutment component 220 and the vaginal wall, while the second abutment component 320 is in contact with the vaginal wall. Opening the water inlet pipe 600 allows for flushing of the vaginal wall corresponding to the first abutment component 220. After the vaginal wall is cleaned, the first abutment component 220 and the second abutment component 320 need to be switched. At this point, the operator pushes the first push rod 410. The push rod 410, when pushed, pressurizes the hydraulic oil in the first channel 430, allowing the hydraulic oil to first enter the first sub-cavity. In section 211, hydraulic oil is synchronously prepared to enter the fourth sub-cavity 312. However, since a delay component 500 is provided in the pipe between the fourth sub-cavity 312 and the first channel 430, the hydraulic oil will only enter the first sub-cavity 211 at this time. The hydraulic oil pushes the first piston rod 213 in the first sub-cavity 211. The first piston rod 213 pushes the first abutting component 220 from its initial position to abut against the vaginal wall. At this time, the movement of the first piston rod 213 is just blocked (a limiting block is provided in the first chamber 210, not shown in the figure).

[0059] The operator continues to push the first push rod 410. The force applied by the first push rod 410 to the hydraulic oil gradually exceeds the elastic force of the spring 510 in the delay component 500. Finally, the force applied by the hydraulic oil to the conical push plate 520 exceeds the elastic force of the spring 510, and a gap appears between the conical push plate 520 and the chamber of the delay component 500. The pipe between the fourth sub-cavity 312 and the first channel 430 is connected, and the hydraulic oil is pushed into the fourth sub-cavity 312 to push the second piston rod 313 to move. The second piston rod 313 pushes the second abutment component 320 to move. Finally, the second abutment component 320 moves away from the vaginal wall. At this time, the water inlet pipe 600 can be opened to flush the vaginal wall corresponding to the second abutment component 320.

[0060] After the vaginal wall at the second contact position is flushed, the vagina at the first contact position needs to be flushed again. The operator can push the second push rod 420. After the second push rod 420 is pushed, the hydraulic oil in the second channel 440 first enters the third sub-cavity 311, pushing the second contact component 320 back to the position of contact with the vaginal wall. At this time, the hydraulic oil in the fourth sub-cavity 312 is discharged. In a specific embodiment, the fourth sub-cavity 312 is connected to the external oil tank through a pipe, and the hydraulic oil enters the oil tank through the pipe. In another specific embodiment, a through hole is provided on the conical push plate 520 in the delay assembly 500 between the fourth sub-cavity 312 and the first channel 430. The through hole extends through the conical push plate 520 along its axial direction, and a single through piece is provided at the end of the through hole. One side of the single through piece is hinged to the top of the conical push plate 520, meaning that the single through piece can be easily opened from the bottom to the top of the conical push plate 520 to make the through hole open, but not in the opposite direction. Therefore, when the volume of the fourth sub-cavity 312 is compressed, the hydraulic oil in the fourth sub-cavity 312 flows into the first channel 430 through the through hole on the conical push plate 520 and the single through piece, and the first push rod 410 is reset. Similarly, when the first push rod 410 pushes in the next round, the hydraulic oil in the second sub-cavity 212 can be discharged through an external oil tank connected to it, or through the delay assembly 500 between the second sub-cavity 212 and the second channel 440. The methods and principles will not be described in detail here. When the second abutment component 320 returns to the position of abutting against the vaginal wall, the second push rod 420 is pushed further, and the delay component 500 in the tube connecting the second channel 440 and the second sub-cavity 212 is opened, and the volume of the second sub-cavity 212 increases. The first piston rod 213 drives the first abutment component 220 away from the vaginal wall, and the vaginal wall at this time is flushed.

[0061] The purpose of setting the delay component 500 in the channel between the fourth sub-cavity 312 and the first channel 430 is that if the delay component 500 is not set so that the second abutment component 320 moves after the first abutment component 220 abuts against the vaginal wall, the first abutment component 220 and the second abutment component 320 will move simultaneously. At this time, the vaginal wall will not be in contact with the abutment component for a period of time. Due to the elasticity of the vagina, it will contract. When the second abutment component 320 moves away from the vaginal wall, the first abutment component 220 slowly moves closer to the vaginal wall and abuts against it again. The patient's vagina will go through a stretching state to a contracting state and then back to a stretching state. The process of the vagina going from a contracting state to a stretching state will cause pain to the patient. Therefore, setting the delay component 500 can completely avoid this process and greatly reduce the pain of the patient during the irrigation process.

[0062] In one specific embodiment, both the first flushing assembly 200 and the second flushing assembly 300 are connected to a water inlet pipe 600 and a nozzle 700. The first abutting assembly 220 and the second abutting assembly 320 are provided with several through holes at equal intervals, each containing a nozzle 700. The other end of each nozzle 700 is connected to the water inlet pipe 600. The nozzle 700 is slidably connected to the inner wall of the through hole in the first abutting assembly 220 and the second abutting assembly 320. The other end of the nozzle 700 is fixed to a flexible plate. An elastic plate 800 is provided on the side of the flexible plate away from the nozzle 700, and the end of the elastic plate 800 away from the flexible plate abuts against a protrusion on the support 100.

[0063] Specifically, the nozzle 700 is movably connected to the through hole, allowing it to partially extend beyond the hole. In this case, the cleaning fluid sprayed from the nozzle 700 forms a fan shape, increasing the cleaning area. However, if the nozzle 700 still extends beyond the through hole when the first abutting component 220 or the second abutting component 320 contacts the vaginal wall, it could cause injury. Therefore, one end of the nozzle 700 is fixed to a flexible plate. An elastic plate 800 is provided on the side of the flexible plate away from the nozzle 700, and the end of the elastic plate 800 away from the flexible plate abuts against a protrusion on the support 100. When the first abutting component 220 moves away from the vaginal wall, it approaches the support 100 under the action of the first piston rod 213. At this time, the elastic plate 800 abuts against the support 100, causing it to be lifted and elastically deformed, thus pushing the nozzle 700 out of the through hole. When the first abutting component 220 approaches the vaginal wall, the first piston rod 213 of the first abutting component 220 moves away from the bracket 100. At this time, the abutment between the elastic plate 800 and the bracket 100 disappears, and the elastic plate 800 returns to its original shape. Then, the elastic plate 800 drives the nozzle 700 to retract into the through hole. Thus, when the first abutting component 220 contacts the vaginal wall, the nozzle 700 will not cause puncture to the vaginal wall.

[0064] In one specific embodiment, this application also discloses a vaginal irrigation method, implemented using the aforementioned vaginal irrigation device, comprising the following steps:

[0065] Step 1: Insert the bracket 100 into the vagina and push the locking component 110 to fix the bracket 100 in the designated locking position;

[0066] Step 2: Irrigate the vagina for time t1;

[0067] Step 3: Push the first push rod 410 so that the first abutting component 220 of the first flushing component 200 and the second abutting component 320 of the second flushing component 300 are at the same height. Continue to push the first push rod 410 until the second abutting component 320 descends to the initial position of the first abutting component 220 of the first flushing component 200, then stop pushing the first push rod 410.

[0068] Step 4: Open the valve of the water inlet pipe for time t2;

[0069] Step 5: Push the second push rod 420 so that the second abutting component 320 of the second flushing component 300 and the first abutting component 220 of the first flushing component 200 are at the same height. Continue to push the second push rod 420 until the first abutting component 220 descends to the position where the second abutting component 320 of the second flushing component 300 was last in step 3, then stop pushing the second push rod 420.

[0070] Step 6: After holding the valve on the inlet pipe for time t3, close the valve.

[0071] Step 7: Unlock the locking component 110 and move the bracket 100 to remove the vaginal irrigation device.

[0072] Specifically, in step one, the locking assembly 110 can prevent relative displacement between the movable part 140 and the handle 120 by rotating the knob through friction, thereby fixing the bracket 100 in the designated locking position.

[0073] In step three, the operator pushes the first push rod 410. After the first push rod 410 is pushed, it pushes the hydraulic oil in the first channel 430. The hydraulic oil first enters the first sub-cavity 211. The hydraulic oil is simultaneously preparing to enter the fourth sub-cavity 312. However, since there is a delay component 500 in the pipe between the fourth sub-cavity 312 and the first channel 430, the hydraulic oil will only enter the first sub-cavity 211 at this time. The hydraulic oil pushes the first piston rod 213 in the first sub-cavity 211. The first piston rod 213 pushes the first abutment component 220 from its initial position to abut against the vaginal wall. At this time, the movement of the first piston rod 213 is just blocked. The operator continues to push the first push rod 410. The force applied by the first push rod 410 to the hydraulic oil gradually exceeds the elastic force of the spring 510 in the delay component 500. Finally, the force applied by the hydraulic oil to the conical push plate 520 exceeds the elastic force of the spring 510, and a gap appears between the conical push plate 520 and the chamber of the delay component 500. The pipe between the fourth sub-cavity 312 and the first channel 430 is connected, and the hydraulic oil is pushed into the fourth sub-cavity 312 to push the second piston rod 313 to move. The second piston rod 313 pushes the second abutment component 320 to move, and finally the second abutment component 320 moves away from the vaginal wall.

[0074] In step five, the operator can push the second push rod 420. After the second push rod 420 is pushed, the hydraulic oil in the second channel 440 first enters the third sub-cavity 311, pushing the second abutment component 320 back to the position abutting against the vaginal wall. At this time, the hydraulic oil in the fourth sub-cavity 312 is discharged. When the second abutment component 320 returns to the position abutting against the vaginal wall, the second push rod 420 is pushed again, and the delay component 500 in the pipe connecting the second channel 440 and the second sub-cavity 212 is opened. The volume of the second sub-cavity 212 increases, and the first piston rod 213 drives the first abutment component 220 away from the vaginal wall.
