Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically, to a vaginal flushing device and a flushing method. Background Art

[0002] Cervical cancer is the most common malignant tumor of the female reproductive tract. Failure to perform regular vaginal dilation and irrigation after treatment of cervical cancer can cause complications such as vaginal adhesion, stenosis, and fibrosis. Therefore, vaginal irrigation devices are used clinically to perform vaginal dilation and irrigation for patients after radiotherapy and chemotherapy.

[0003] During the vaginal irrigation process, the existing vaginal douche needs to be inserted into the vagina and contact the inner wall of the vagina to stretch the vagina. The part of the vaginal douche that contacts the vagina is difficult to be doucheed, thus resulting in incomplete vaginal douche of the patient and poor douche effect. Summary of the invention

[0046] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0047] As Figures 1 to 5 shown, a vaginal irrigation device according to an embodiment of the present application includes a bracket 100 for forming the external contour of the vaginal irrigation device. The bracket 100 has a locking assembly 110; a first irrigation assembly 200 disposed on the bracket 100; a second irrigation assembly 300 cooperating with the first irrigation assembly 200 to irrigate the inner wall of the vagina; and further includes: a switching assembly 400, the switching assembly 400 is disposed on the bracket 100 and acts on the first irrigation assembly 200 and the second irrigation assembly 300 to enable the first irrigation assembly 200 and the second irrigation assembly 300 to alternately irrigate the inner wall of the vagina.

[0048] Specifically, the bracket 100 includes a handle 120, a fixing portion 130 and a movable portion 140. The bracket 100 is in the shape of an irregular cylinder as a whole, which is convenient for inserting into the vagina of a patient. The handle 120 of the bracket 100 is used for an operator to hold the entire vaginal irrigation device. One end of the handle 120 is connected to the fixing portion 130, and there is no relative displacement between the fixing portion 130 and the handle 120. The movable portion 140 is movably connected to the handle 120, and the movable portion 140 can move relative to the handle 120 so that the entire vaginal irrigation device can open a certain distance, that is, the opening and closing distance between the movable portion 140 and the fixing portion 130 can be adjusted to adapt to the use of different patients. A locking assembly 110 is provided in the groove of the movable portion 140. In a specific embodiment, the locking assembly 110 is a knob, and when the knob rotates, relative displacement between the movable portion 140 and the handle 120 can be prevented by friction.

[0049] The vaginal irrigation device includes a first irrigation assembly 200 and a second irrigation assembly 300. Both the first irrigation assembly 200 and the second irrigation assembly 300 are divided into two parts, which are symmetrically arranged on the fixed part 130 and the movable part 140 of the bracket 100 respectively. For the convenience of subsequent description, the parts of the first irrigation assembly 200 and the second irrigation assembly 300 on the movable part 140 will be described. The first irrigation assembly 200 and the second irrigation assembly 300 are arranged in sequence in the length direction of the vaginal irrigation device. The first irrigation assembly 200 is close to the handle 120, and the second irrigation assembly 300 is far from the handle 120. The first irrigation assembly 200 and the second irrigation assembly 300 can alternately irrigate the inner wall of the vagina. That is, when the first irrigation assembly 200 irrigates the inner wall of the vagina, the second irrigation assembly 300 bears the supporting role for the inner wall of the vagina. On the contrary, when the second irrigation assembly 300 irrigates the inner wall of the vagina, the first irrigation assembly 200 bears the supporting role for the inner wall of the vagina. The first irrigation assembly 200 and the second irrigation assembly 300 work alternately through the switching assembly 400, that is, the operator operates the switching assembly 400 to realize the alternate irrigation of the inner wall of the vagina by the first irrigation assembly 200 and the second irrigation assembly 300.

[0050] More specifically, the first irrigation assembly 200 includes a first chamber 210 and a first abutting assembly 220. A first piston rod 213 is provided in the first chamber 210 to divide 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; wherein, one end of the first chamber 210 away from the first abutting assembly 220 is communicated with the switching assembly 400.

[0051] The first piston rod 213 in the first chamber 210 supports the first abutting assembly 220. One end of the first abutting assembly 220 abuts against the inner wall of the vagina. The first piston rod 213 moves in the first chamber 210, and its piston block divides the first chamber 210 into a first sub-chamber 211 and a second sub-chamber 212. When the first piston rod 213 controls the first abutting assembly 220 to approach the inner wall of the vagina, the volume of the first sub-chamber 211 becomes larger and the volume of the second sub-chamber 212 becomes smaller; when the first piston rod 213 controls the first abutting assembly 220 to move away from the inner wall of the vagina, the volume of the first sub-chamber 211 becomes smaller and the volume of the second sub-chamber 212 becomes larger. The switching assembly 400 communicates the first sub-chamber 211 and the second sub-chamber 212. Therefore, the switching assembly 400 can control whether the first abutting assembly 220 approaches or moves away from the inner wall of the vagina by controlling the volume sizes of the first sub-chamber 211 and the second sub-chamber 212.

[0052] Similarly, the second flushing assembly 300 includes a second chamber 310 and a second abutting assembly 320. A second piston rod 313 is disposed in the second chamber 310 to divide 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 abutting assembly 320. Wherein, one end of the second chamber 310 away from the second abutting assembly 320 communicates with the switching assembly 400.

[0053] The second piston rod 313 in the second chamber 310 supports the second abutting assembly 320. One end of the second abutting assembly 320 abuts against the inner wall of the vagina. The second piston rod 313 moves in the second chamber 310, and its piston block divides the second chamber 310 into a third sub-chamber 311 and a fourth sub-chamber 312. When the second piston rod 313 controls the second abutting assembly 320 to approach the inner wall of the vagina, the volume of the third sub-chamber 311 increases, and the volume of the fourth sub-chamber 312 decreases; when the second piston rod 313 controls the second abutting assembly 320 to move away from the inner wall of the vagina, the volume of the third sub-chamber 311 decreases, and the volume of the fourth sub-chamber 312 increases. The switching assembly 400 communicates with the third sub-chamber 311 and the fourth sub-chamber 312. Therefore, the switching assembly 400 can control whether the second abutting assembly 320 approaches or moves away from the inner wall of the vagina by controlling the volume of the third sub-chamber 311 and the fourth sub-chamber 312.

[0054] In a 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. The first channel 430 is filled with hydraulic oil. The first channel 430 communicates with the first sub-chamber 211 and the fourth sub-chamber 312. The switching assembly 400 further includes a second push rod 420 and a second channel 440. The second push rod 420 extends into the second channel 440. The second channel 440 is filled with hydraulic oil. The second channel 440 communicates with the second sub-chamber 212 and the third sub-chamber 311. Both the second sub-chamber 212 and the third sub-chamber 311 communicate with the fuel tank.

[0055] Specifically, the switching component 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 for the operator to operate. The operator can push and pull the first push rod 410 to control the movement of the first abutting component 220 and the second abutting component 320; similarly, the operator can push and pull the second push rod 420 to control the movement of the first abutting component 220 and the second abutting component 320. One end of the first push rod 410 extends into the first channel 430. The first channel 430 is a channel provided 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., and there is no limitation here. When the first push rod 410 is pushed, the hydraulic oil in the first channel 430 is pushed. Since the first channel 430 communicates with the first sub-chamber 211 and the fourth sub-chamber 312, the hydraulic oil will push the first piston rod 213 in the first sub-chamber 211 to move, and push the second piston rod 313 in the fourth sub-chamber 312 to move, so that the first abutting component 220 and the second abutting component 320 approach and move away from the inner wall of the vagina. Both the first abutting component 220 and the second abutting component 320 are configured to be arc-shaped, which is convenient for the vaginal irrigation device to enter the vagina without causing harm to the vagina, and can reduce the discomfort of the patient when the first abutting component 220 and the second abutting component 320 contact the inner wall of the vagina.

[0056] In a specific embodiment, a delay component 500 is provided in the connecting pipe of the second sub-chamber 212 and the second channel 440, and a delay component 500 is provided in the connecting pipe of the fourth sub-chamber 312 and the first channel 430. The delay component 500 includes a spring 510 and a conical push piece 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 push piece 520. The conical push piece 520 abuts against the oil inlet of the delay component 500.

[0057] Specifically, the delay component 500 is a chamber provided in the connecting pipe of the second sub-chamber 212 and the second channel 440 and the connecting pipe of the fourth sub-chamber 312 and the first channel 430. A spring 510 and a conical push piece 520 are provided in the chamber. 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 push piece 520. The conical surface of the conical push piece 520 abuts against the oil inlet of the delay component 500. Only when the force applied to the conical surface of the conical push piece 520 is greater than the elastic force of the spring 510 can the conical push piece 520 be pushed open. At this time, the second sub-chamber 212 and the second channel 440 can be communicated. Similarly, only when the force applied to the conical surface of the conical push piece 520 is greater than the elastic force of the spring 510 can the conical push piece 520 be pushed open, and the fourth sub-chamber 312 and the first channel 430 can be communicated.

[0058] The working processes of the first flushing component 200 and the second flushing component 300 are as follows: When the first push rod 410 and the second push rod 420 are both in their original positions, the first abutting component 220 is at the position as shown in Figure 1 , that is, there is a certain gap between the first abutting component 220 and the vaginal inner wall, and the second abutting component 320 is in contact with the vaginal inner wall. At this time, when the water inlet pipe 600 is opened, the vaginal inner wall corresponding to the first abutting component 220 can be flushed. After the vaginal inner wall at this place is flushed clean, the first abutting component 220 and the second abutting component 320 need to change positions. At this time, the operator pushes the first push rod 410. After the first push rod 410 is pushed, the hydraulic oil in the first channel 430 is pushed. The hydraulic oil first enters the first sub-chamber 211, and the hydraulic oil is synchronously ready to enter the fourth sub-chamber 312. However, since there is a delay component 500 in the pipeline between the fourth sub-chamber 312 and the first channel 430, the hydraulic oil will only enter the first sub-chamber 211 at this time. The hydraulic oil pushes the first piston rod 213 in the first sub-chamber 211, and the first piston rod 213 pushes the first abutting component 220 to move from the initial position to abut against the vaginal wall. At this time, the first piston rod 213 just meets an obstacle (there is a limiting block in the first chamber 210, not shown in the figure).

[0059] The operator continues to push the first push rod 410. The force exerted by the first push rod 410 on the hydraulic oil gradually becomes greater than the elastic force of the spring 510 in the delay component 500. Finally, the force exerted by the hydraulic oil on the conical push piece 520 is greater than the elastic force of the spring 510, so there is a gap between the conical push piece 520 and the chamber of the delay component 500. The pipeline between the fourth sub-chamber 312 and the first channel 430 is connected. Then, the hydraulic oil is pushed into the fourth sub-chamber 312 to push the second piston rod 313 to move, and the second piston rod 313 pushes the second abutting component 320 to move. Finally, the second abutting component 320 moves away from the vaginal inner wall. At this time, when the water inlet pipe 600 is opened, the vaginal inner wall corresponding to the second abutting component 320 can be flushed.

[0060] When the inner wall of the vagina at the second abutment position is flushed, the vagina at the first abutment position needs to continue to be flushed, and 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-chamber 311, and pushes the second abutment assembly 320 back to the position abutting the inner wall of the vagina. At this time, the hydraulic oil in the fourth sub-chamber 312 is discharged. In a specific embodiment, the fourth sub-chamber 312 is connected to an external oil tank through a pipeline, and the hydraulic oil enters the oil tank through the pipeline. In another specific embodiment, a through hole is provided on the conical push piece 520 in the delay assembly 500 between the fourth sub-chamber 312 and the first channel 430. The through hole penetrates the conical push piece 520 along the axial direction of the conical push piece 520, and a single-pass piece is provided at the end of the through hole. One side of the single-pass piece is hinged at the top of the conical push piece 520, that is, the single-pass piece can be easily opened from the bottom to the top of the conical push piece 520 to make the through hole connected, and the through hole cannot be connected in the opposite direction. Therefore, when the volume of the fourth sub-chamber 312 is compressed, the hydraulic oil in the fourth sub-chamber 312 flows into the first channel 430 through the through hole provided on the conical push piece 520 and the single-pass piece, and the first push rod 410 is reset. Similarly, when the first push rod 410 pushes the next round, the hydraulic oil in the second sub-chamber 212 can be unloaded through an external oil tank connected to it, or through the delay assembly 500 between the second sub-chamber 212 and the second channel 440. The method and principle are not repeated here. When the second abutment component 320 returns to the position abutting against the inner wall of the vagina, the second push rod 420 continues to be pushed, and the delay component 500 in the pipe connecting the second channel 440 and the second sub-chamber 212 is opened, the volume of the second sub-chamber 212 increases, and the first piston rod 213 drives the first abutment component 220 away from the inner wall of the vagina, and the inner wall of the vagina at that location is flushed.

[0061] The purpose of setting the delay component 500 in the pipeline between the fourth sub-cavity 312 and the first channel 430 is that if there is no delay component 500, the second abutment component 320 will move after the first abutment component 220 abuts against the inner wall of the vagina, then the first abutment component 220 and the second abutment component 320 will move simultaneously. At this time, there will be a period of time when the inner wall of the patient's vagina has no abutment component in contact with it. Since the vagina has elasticity, it will shrink. When the second abutment component 320 moves away from the inner wall of the vagina, the first abutment component 220 slowly approaches the inner wall of the vagina and then abuts against the inner wall of the vagina. The patient's vagina will experience the process of being stretched to a contracted state and then stretched. The process of the vagina changing from a contracted state to a stretched component will cause pain to the patient. Therefore, setting the delay component 500 can completely avoid the occurrence of this process, greatly reducing the patient's pain during the flushing process.

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

[0063] Specifically, the nozzle 700 is arranged to be movably connected with the through hole, and the nozzle 700 can partially extend out of the through hole. At this time, the cleaning liquid sprayed by the nozzle 700 can present a fan shape, which increases the cleaning area. However, when the first abutting component 220 or the second abutting component 320 contacts the inner wall of the vagina, if the nozzle 700 still extends out of the through hole, it will cause stabs to the inner wall of the vagina. Therefore, one end of the nozzle 700 is fixed on a soft plate, and an elastic plate 800 is provided on the side of the soft plate away from the nozzle 700, and the elastic plate 800 is abutted against the protrusion provided on the bracket 100 away from one end of the soft plate. When the first abutting component 220 is away from the inner wall of the vagina, the first abutting component 220 is driven by the first piston rod 213 to approach the bracket 100, and at this time, the elastic plate 800 abuts against the bracket 100, and then the elastic plate 800 is lifted up and elastically deformed, and then the elastic plate 800 pushes the nozzle 700 out of the through hole. When the first abutment component 220 approaches the inner wall of the vagina, the first abutment component 220 is driven away from the bracket 100 by the first piston rod 213. At this time, the abutment between the elastic plate 800 and the bracket 100 disappears, and the elastic plate 800 restores its original shape, and then the elastic plate 800 drives the nozzle 700 to retract into the through hole. Then, when the first abutment component 220 contacts the inner wall of the vagina, the nozzle 700 will not cause puncture to the inner wall of the vagina.

[0064] In a specific embodiment, the present application also discloses a vaginal flushing method, which is implemented using the above-mentioned vaginal flushing device and comprises the following steps:

[0065] Step 1: insert the stent 100 into the vagina, and push the locking assembly 110 so that the stent 100 is fixed at a designated locking position;

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

[0067] Step 3: Push the first push rod 410 to make the first abutting component 220 of the first flushing assembly 200 and the second abutting component 320 of the second flushing assembly 300 at the same height, and continue to push the first push rod 410 until the second abutting component 320 descends to the position where the first abutting component 220 of the first flushing assembly 200 was initially located, then stop pushing the first push rod 410;

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

[0069] Step 5: Push the second push rod 420 to make the second abutting component 320 of the second flushing assembly 300 and the first abutting component 220 of the first flushing assembly 200 at the same height, and 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 assembly 300 was finally located in Step 3, then stop pushing the second push rod 420;

[0070] Step 6: Keep the valve of the water inlet pipe open for t3 time and then close the valve;

[0071] Step 7: Unlock the locking component 110, move the bracket 100 and take out the vaginal flushing device.

[0072] Specifically, in Step 1, the locking component 110 can prevent relative displacement between the movable part 140 and the handle 120 through friction by rotating the knob, so that the bracket 100 is fixed at the designated locking position.

[0073] In Step 3, the operator pushes the first push rod 410. After the first push rod 410 is pushed, the hydraulic oil in the first channel 430 is pushed. The hydraulic oil first enters the first sub-chamber 211, and the hydraulic oil is synchronously ready to enter the fourth sub-chamber 312. However, since there is a delay component 500 in the pipeline between the fourth sub-chamber 312 and the first channel 430, the hydraulic oil will only enter the first sub-chamber 211 at this time. The hydraulic oil pushes the first piston rod 213 in the first sub-chamber 211, and the first piston rod 213 pushes the first abutting component 220 to move from the initial position to abut against the vaginal wall. At this time, the first piston rod 213 is just blocked. The operator continues to push the first push rod 410. The force exerted by the first push rod 410 on the hydraulic oil gradually becomes greater than the elastic force of the spring 510 in the delay component 500. Finally, the force exerted by the hydraulic oil on the conical push piece 520 is greater than the elastic force of the spring 510, so there is a gap between the conical push piece 520 and the chamber of the delay component 500, and the pipeline between the fourth sub-chamber 312 and the first channel 430 is connected. Then the hydraulic oil is pushed into the fourth sub-chamber 312 to push the second piston rod 313 to move, and the second piston rod 313 pushes the second abutting component 320 to move. Finally, the second abutting component 320 moves away from the vaginal inner 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 subchamber 311, pushing the second abutting assembly 320 back to the position where it abuts against the vaginal inner wall. At this time, the hydraulic oil in the fourth subchamber 312 is discharged. When the second abutting assembly 320 returns to the position where it abuts against the vaginal inner wall, if the second push rod 420 is continuously pushed, the delay assembly 500 in the pipeline connecting the second channel 440 and the second subchamber 212 is opened, then the volume of the second subchamber 212 increases, and the first piston rod 213 drives the first abutting assembly 220 away from the vaginal inner wall.
