Description

Technical Field

[0001] The invention relates to the technical field of medical care products, in particular to a negative pressure drainage device for recto-vaginal fistula. Background Art

[0002] Rectovaginal fistula is divided into congenital and acquired. Congenital is mainly caused by congenital factors. Acquired rectovaginal fistula has complex causes and is commonly seen in birth trauma, gynecological pelvic surgery, rectal anastomotic fistula after rectal cancer surgery, advanced cancer, infection, radiation damage, etc.

[0003] The formation of acquired rectovaginal fistula is as follows:

[0004] 1. After the formation of anorectal peri-infection abscess, if not treated promptly or improperly, the abscess may penetrate the recto-vaginal septum and lead to fistula formation;

[0005] 2. When injecting the sclerosant, the local drug concentration is too high or the dosage is too large, which may cause local tissue infection, necrosis and fistula formation;

[0006] 3. Gynecological tumor surgery, if the tumor adheres to the rectal mucosa or invades the rectum, the rectum may be damaged during peeling, and fistula may easily form after surgery if not handled properly;

[0007] 4. Common in obstetric delivery, if the perineum is improperly protected or the perineum is incised and deviated to the posterior longitudinal median position, it can also lead to the formation of rectovaginal fistula;

[0008] 5. Rectovaginal penetrating injuries can directly create a channel between the rectum and the vagina. If the injury is not discovered and treated in time, rectovaginal fistula is very likely to form.

[0009] Whether it is congenital rectovaginal fistula or acquired rectovaginal fistula, it is difficult to completely treat and recover through surgery. Only through better intervention can it heal well.

[0010] At present, the intervention treatment of rectovaginal fistula is usually to insert a flushing tube into the patient's rectovaginal fistula from the vagina to flush and sterilize the patient's rectovaginal fistula, and to negatively pressure the residual fluid therein so that the patient's rectovaginal fistula remains sterile for a certain period of time to achieve rapid healing. However, the patient often cannot help but discharge vaginal secretions, urinate and / or defecate during this period of time. Because the patient's rectovaginal fistula is connected to the patient's vagina and rectum, the patient's vaginal secretions, urine and / or feces may continue to enter the patient's rectovaginal fistula, causing the patient's rectovaginal fistula to contain bacteria and residual fluid again, resulting in poor healing effect during this period of time.

[0011] However, there is no device currently available for use that can effectively promote the rapid healing of a patient's rectovaginal fistula.

[0012] Therefore, based on the human body structure and clinical experience, the inventor of this patent designed this application to solve the relevant technical problems. Summary of the invention

[0061] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, so as to more clearly and intuitively understand the inventive essence of the present invention.

[0062] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown;

[0063] The present invention provides a rectovaginal fistula negative pressure drainage device 1000, comprising a vaginal drainage tube 10, a rectal drainage tube 20 and a rectovaginal fistula negative pressure suction tube 30;

[0064] The outer wall of the vaginal drainage tube 10 is provided with a first air bag 101 and a second air bag 102 in sequence from top to bottom near the upper end thereof; the outer wall of the vaginal drainage tube 10 is provided with a drainage port 103 between the first air bag 101 and the second air bag 102; the interior of the vaginal drainage tube 10 is provided with a first drainage cavity 104 and a second drainage cavity 105 in parallel; the upper part of the first drainage cavity 104 is communicated with the upper end of the vaginal drainage tube 10; the upper part of the second drainage cavity 105 is communicated with the drainage port 103;

[0065] In addition, the outer wall of the rectal drainage tube 20 is provided with a third airbag 201 and a fourth airbag 202 in sequence from top to bottom near the upper end thereof; the distance between the third airbag 201 and the fourth airbag 202 is equal to the distance between the first airbag 101 and the second airbag 102;

[0066] The rectovaginal fistula negative pressure suction tube 30 can be inserted into the second drainage cavity 105 movably up and down, and its upper end passes through the drainage port 103 to form a negative pressure drainage part 301 suitable for being inserted into the patient's rectovaginal fistula 4000.

[0067] Based on the above, it is clear that when the present application is implemented, it is mainly used as a negative pressure drainage device 1000 for rectovaginal fistula.

[0068] The present application mainly includes a vaginal drainage tube 10, a rectal drainage tube 20 and a rectovaginal fistula negative pressure suction tube 30. When in use, the patient's vagina 2000, the patient's rectum 3000 and the patient's rectovaginal fistula 4000 are first rinsed and sterilized, and then the vaginal drainage tube 10 described in the present application is immediately inserted into the patient's vagina 2000, and the rectal drainage tube 20 is immediately inserted into the patient's rectum 3000. Under ultrasound or other imaging, the first end of the patient's rectovaginal fistula 4000 is located between the first air bag 101 and the second air bag 102 provided on the outer wall of the vaginal drainage tube 10, and is directly opposite to the drainage port 103 provided on the outer wall of the vaginal drainage tube 10, and the second end of the patient's rectovaginal fistula 4000 is located between the third air bag 201 and the fourth air bag 202 provided on the outer wall of the rectal drainage tube 20.

[0069] Then, the recto-vaginal fistula negative pressure suction tube 30 is inserted into the second drainage cavity 105 of the vaginal drainage tube 10, so that the upper negative pressure drainage part 301 thereof passes through the drainage port 103 provided on the outer wall of the vaginal drainage tube 10, and the upper negative pressure drainage part 301 thereof will smoothly extend into the patient's recto-vaginal fistula 4000.

[0070] In this way, a negative pressure aspirator 5000 can be connected to the lower end of the recto-vaginal fistula negative pressure suction tube 30 to suck out the residual fluid in the patient's recto-vaginal fistula 4000, so as to facilitate the rapid healing of the patient's recto-vaginal fistula 4000. Figure 7 shown.

[0071] During this process, the inflated first airbag 101 is used to block secretions that may flow out of the patient's vagina 2000, the inflated second airbag 102 is used to block residual liquid that may be sucked into the opening of the patient's vagina 2000 by negative pressure, the inflated third airbag 201 is used to block fecal fluid that may flow out of the patient's rectum 3000, and the inflated fourth airbag 202 is used to block residual liquid that may be sucked into the stoma of the patient's rectum 3000 by negative pressure, so that the patient's recto-vaginal fistula 4000 after the residual liquid is sucked out by negative pressure can be fully sealed, so that the secretions of the patient's vagina 2000, the residual liquid at the vaginal opening, the fecal fluid of the patient's rectum 3000 and the residual liquid at the rectostomy are not easy to enter the patient's recto-vaginal fistula 4000, so that the patient's recto-vaginal fistula 4000 can indeed remain dry and sterile for a certain period of time to achieve rapid healing and repair.

[0072] At the same time, the vaginal drainage tube 10 described in the present application is fixed into the patient's vagina 2000, and the secretions discharged from the patient's vagina 2000 will flow out along the lower end of the vaginal drainage tube 10. The rectal drainage tube 20 described in the present application is fixed into the patient's rectum 3000, and the fecal fluid discharged from the patient's rectum 3000 will flow out along the lower end of the rectal drainage tube 20. In this way, the present application will not affect the patient's normal physiology and life when in use, making the present application highly adaptable.

[0073] Furthermore, the present application is highly practical and reliable to use, resulting in good use effects.

[0074] Furthermore, in this embodiment, a developing ring A 106 is provided on the outer wall of the vaginal drainage tube 10 beside the drainage port 103 ; a developing ring B 107 is provided on the outer wall of the rectal drainage tube 20 between the third airbag 201 and the fourth airbag 202 .

[0075] Therefore, when the vaginal drainage tube 10 described in the present application is inserted into the patient's vagina 2000, and the rectal drainage tube 20 described in the present application is inserted into the patient's rectum 3000, under ultrasound or other development, the development circle A 106 is adjacent to the first end of the patient's recto-vaginal fistula 4000, and the development circle B 107 is adjacent to the second end of the patient's recto-vaginal fistula 4000, so that the first end of the patient's recto-vaginal fistula 4000 is limited between the first air bag 101 and the second air bag 102, and is directly opposite to the drainage port 103 provided on the outer wall of the vaginal drainage tube 10, and the second end of the patient's recto-vaginal fistula 4000 is limited between the third air bag 201 and the fourth air bag 202, so that the present application is convenient and reliable to use.

[0076] Preferably, in this embodiment, the outer wall of the vaginal drainage tube 10 is respectively provided with a developing ring A 106 on the upper and lower sides of the drainage port 103; the outer wall of the rectal drainage tube 20 is provided with two developing rings B107 between the third air bag 201 and the fourth air bag 202; the distance between the two developing rings B107 is equal to the distance between the two developing rings A106.

[0077] Therefore, when the vaginal drainage tube 10 described in the present application is inserted into the patient's vagina 2000, and the rectal drainage tube 20 described in the present application is inserted into the patient's rectum 3000, under ultrasound or other development, the middle part between the two development circles A106 is opposite to the first end of the patient's recto-vaginal fistula 4000, and the middle part between the two development circles B107 is opposite to the second end of the patient's recto-vaginal fistula 4000, so that the first end of the patient's recto-vaginal fistula 4000 is limited between the first air bag 101 and the second air bag 102, and is more accurately opposite to the drainage port 103 provided on the outer wall of the vaginal drainage tube 10, and the second end of the patient's recto-vaginal fistula 4000 is more accurately limited between the third air bag 201 and the fourth air bag 202, making the present application more convenient and reliable to use.

[0078] Furthermore, in a specific implementation, the upper portion of the second drainage cavity 105 is bent outward to form an arc-shaped transition portion 1051 , and the arc-shaped transition portion 1051 is communicated with the drainage port 103 .

[0079] Therefore, the arc-shaped transition portion 1051 provided must have a good guiding effect, so that after the rectovaginal fistula negative pressure suction tube 30 is inserted from bottom to top into the second drainage cavity 105 of the vaginal drainage tube 10, its upper end can smoothly pass through the drainage port 103 provided on the outer wall of the vaginal drainage tube 10 along the arc-shaped transition portion 1051, and after aligning the position, it can be smoothly extended into the patient's rectovaginal fistula 4000, making the reliability of the use of this application better.

[0080] Furthermore, in the present technical solution, the lower end of the vaginal drainage tube 10 is bifurcated to form a first plug connector 107 and a second plug connector 108;

[0081] The lower portion of the first drainage cavity 104 is connected to the first plug connector 107 ; the lower portion of the second drainage cavity 105 is connected to the second plug connector 108 ; and the lower end of the rectovaginal fistula negative pressure suction tube 30 extends from the second plug connector 108 .

[0082] Moreover, in the present embodiment, the first plug connector 107 is externally connected to a first sealing cover 109 for sealing it; the outer wall of the lower end of the rectovaginal fistula negative pressure suction tube 30 is protruding outwardly with an outer protrusion 302 suitable for being inserted into the second plug connector 108 for limiting its own insertion depth and sealing the second plug connector 108.

[0083] In this way, when the patient does not need to discharge secretions, such as menstrual fluid, the first sealing cover 109 can be covered on the outside of the first plug connector 107. When the patient needs to discharge secretions, such as menstrual fluid, the first sealing cover 109 can be unplugged from the first plug connector 107.

[0084] Furthermore, after the outer protrusion 302 is inserted into the second plug connector 108, it can seal the second plug connector 108 so that a negative pressure aspirator 5000 is externally connected to the lower end thereof, and when the residual liquid in the patient's recto-vaginal fistula 4000 is negatively attracted by the external negative pressure aspirator 5000, a relatively stable negative pressure state can be maintained in the patient's recto-vaginal fistula 4000, so as to avoid as much as possible the poor negative pressure aspiration effect caused by air leakage at the plug interface at the lower end of the second plug connector 108.

[0085] At the same time, after the outer protrusion 302 is inserted into the second plug connector 108, it can also limit the insertion depth of the recto-vaginal fistula negative pressure suction tube 30, so that when the present application is used to perform negative pressure suction on the residual liquid in the patient's recto-vaginal fistula 4000, the depth of the negative pressure drainage part 301 at the upper end of the recto-vaginal fistula negative pressure suction tube 30 inserted into the patient's recto-vaginal fistula 4000 can be kept stable, making it difficult to shift forward and backward and cause dislocation and slippage, making the present application more reliable in use.

[0086] Furthermore, in a specific implementation, the present application further includes a medical guide wire 40 for pulling the rectovaginal fistula negative pressure suction tube 30 to move up and down along the second drainage cavity 105;

[0087] Among them, the length of the medical guide wire 40 is equal to the length of the rectovaginal fistula negative pressure suction tube 30, and it can be removably inserted into the rectovaginal fistula negative pressure suction tube 30, and the lower end of the medical guide wire 40 is provided with a cap 401 suitable for reaching the lower end of the rectovaginal fistula negative pressure suction tube 30.

[0088] Therefore, when using this application, refer to Figure 4 As shown, the recto-vaginal fistula negative pressure suction tube 30 and the medical guide wire 40 therein are grasped in advance by hand, so that the negative pressure drainage part 301 at the upper end of the recto-vaginal fistula negative pressure suction tube 30 is retracted into the second drainage cavity 105, so that the vaginal drainage tube 10 is inserted into the patient's vagina 2000 to a suitable depth under ultrasound or the like, and the rectal drainage tube 20 is inserted into the patient's rectum 3000 to a suitable depth, so that the first end of the patient's recto-vaginal fistula 4000 is located between the first air bag 101 and the second air bag 102 provided on the outer wall of the vaginal drainage tube 10, and is directly opposite to the drainage port 103 provided on the outer wall of the vaginal drainage tube 10, and the second end of the patient's recto-vaginal fistula 4000 is located between the third air bag 201 and the fourth air bag 202 provided on the outer wall of the rectal drainage tube 20.

[0089] It should be added that, in the specific implementation, the outer wall of the vaginal drainage tube 10 of the present application is provided with a first gas guide connector 110 near its lower end; the outer wall of the rectal drainage tube 20 is provided with a second gas guide connector 204 near its lower end;

[0090] An air channel A111 is provided in the outer wall of the vaginal drainage tube 10 between the first air bag 101 and the second air bag 102 to connect them; an air channel B112 is provided in the outer wall of the vaginal drainage tube 10 between the second air bag 102 and the first air guide connector 110 to connect them;

[0091] An air guide channel C205 is provided in the outer wall of the rectal drainage tube 20 between the third air bag 201 and the fourth air bag 202 to connect them; an air guide channel D206 is provided in the outer wall of the rectal drainage tube 20 between the fourth air bag 202 and the second air guide connector 204 to connect them.

[0092] Based on this, the present application also includes a gas guiding three-way tube 50, an inflatable balloon 60, a first flow limiting clamp 70 and a second flow limiting clamp 80;

[0093] Among them, the first end of the gas guiding three-way tube 50 is connected to the first gas guiding connector 110, the second end is connected to the second gas guiding connector 204, and the third end is connected to the inflatable balloon 60; the first flow limiting clamp 70 can be opened and closed and clamped outside the first end of the gas guiding three-way tube 50; the second flow limiting clamp 80 can be opened and closed and clamped outside the second end of the gas guiding three-way tube 50.

[0094] Therefore, when the first flow limiting clamp 70 is opened, the first airbag 101 and the second airbag 102 can be inflated synchronously through the inflatable balloon 60, so that the periphery of the airbag 101 and the second airbag 102 swell to a certain volume and then the first flow limiting clamp 70 is closed, so that the first airbag 101 and the second airbag 102 can be better pressed against the periphery of the inner wall of the patient's vagina 2000, so that the first end of the patient's recto-vaginal fistula 4000 can be sealed.

[0095] Similarly, when the second flow limiting clamp 80 is opened, the third airbag 201 and the fourth airbag 202 can be inflated synchronously through the inflatable balloon 60, so that their peripheries swell to a certain volume and then the second flow limiting clamp 80 is closed, so that they can better press against the periphery of the inner wall of the patient's rectum 3000, so that the second end of the patient's recto-vaginal fistula 4000 is sealed.

[0096] For details, please refer to Figure 5 As shown;

[0097] Furthermore, the first flow limiting clamp 70 and the second flow limiting clamp 80 are provided because the inner diameters of the vagina 2000 and the rectum of different patients are different in size, so that the first flow limiting clamp 70 can be opened according to the inner diameters of the vagina 2000 of different patients, so that the first airbag 101 and the second airbag 102 can be inflated synchronously to a suitable amount through the inflatable balloon 60 to press against the inner wall of the vagina 2000 of different patients. It can also be ensured that the second flow limiting clamp 80 can be opened according to the inner diameters of the rectum 3000 of different patients, so that the third airbag 201 and the fourth airbag 202 can be inflated synchronously to a suitable amount through the inflatable balloon 60 to press against the inner wall of the rectum 3000 of different patients, making the application more adaptable and flexible in use.

[0098] Then, refer to Figure 6 As shown, the medical guide wire 40 can be pushed upward to drive the rectovaginal fistula negative pressure suction tube 30 to move upward along the second drainage cavity 105, and the negative pressure drainage portion 301 at the upper end of the rectovaginal fistula negative pressure suction tube 30 will extend outward from the drainage port 103 along the arc-shaped transition portion 1051 at the upper part of the second drainage cavity 105, and directly extend into the patient's rectovaginal fistula 4000 aligned with its position to a certain depth.

[0099] In this way, the entire fixation of the present application in the patient's vagina 2000, the patient's rectum 3000 and the patient's recto-vaginal fistula 4000 is completed.

[0100] Subsequent, see Figure 7 As shown, the medical guide wire 40 can be withdrawn, and a negative pressure aspirator 5000 is connected to the lower end of the recto-vaginal fistula negative pressure aspiration tube 30 to perform negative pressure aspiration on the residual fluid in the patient's recto-vaginal fistula 4000.

[0101] At the same time, when the patient needs to urinate during this process, the first sealing cover 109 can be unplugged from the first plug connector 107, and a urine bag can be connected to the first plug connector 107. Similarly, when the patient needs to defecate during this process, a feces bag can be connected to the rectal drainage tube 20.

[0102] In this way, even if the patient's urination and defecation are very convenient, it will not affect the use of the present application to perform negative pressure suction on the residual liquid in the patient's recto-vaginal fistula 4000. Conversely, when the present application is used to perform negative pressure suction on the residual liquid in the patient's recto-vaginal fistula 4000, it will not affect the patient's normal urination and defecation.

[0103] It is further necessary to add that, in a specific implementation, the outer wall of the negative pressure drainage portion 301 of the rectovaginal fistula negative pressure suction tube 30 described in the present application is evenly provided with a plurality of negative pressure drainage holes 3011 along its length direction.

[0104] As a result, the residual liquid in the patient's recto-vaginal fistula 4000 can be sucked outwards with negative pressure more evenly, dispersedly and quickly.

[0105] It should be further added that, in a specific implementation, the lower end of the rectal drainage tube 20 is externally connected to a second sealing cover 207 for sealing the lower end of the rectal drainage tube 20;

[0106] In this way, when the patient does not need to defecate, the second sealing cover 207 can be covered on the lower end of the rectal drainage tube 20, and when the patient needs to defecate, the second sealing cover 207 can be pulled away from the lower end of the rectal drainage tube 20.

[0107] Furthermore, in a specific implementation, the distance between the upper end of the vaginal drainage tube 10 and the first airbag 101 and the distance between the upper end of the rectal drainage tube 20 and the third airbag 201 are preferably set to 3.0 cm.

[0108] Other embodiments and the like are not described one by one here.

[0109] In summary, the rectovaginal fistula negative pressure drainage device 1000 provided by the present invention, when implemented, includes a vaginal drainage tube 10, a rectal drainage tube 20 and a rectovaginal fistula negative pressure suction tube 30. When used, the patient's vagina 2000, rectum and rectovaginal fistula are first rinsed and sterilized, and then the vaginal drainage tube 10 described in the present application is immediately inserted into the patient's vagina 2000, and the rectal drainage tube 20 is immediately inserted into the patient's rectum 3000, and under ultrasound or other imaging, the first end of the patient's rectovaginal fistula 4000 is located at the first air bag 10 provided on the outer wall of the vaginal drainage tube 10. 1 and the second air bag 102, and facing the drainage port 103 provided on the outer wall of the vaginal drainage tube 10, and so that the second end of the patient's recto-vaginal fistula 4000 is located between the third air bag 201 and the fourth air bag 202 provided on the outer wall of the recto-vaginal drainage tube 20, and then, the recto-vaginal fistula negative pressure suction tube 30 is inserted into the second drainage cavity 105 of the vaginal drainage tube 10, so that the upper end negative pressure drainage part 301 thereof passes through the drainage port 103 provided on the outer wall of the vaginal drainage tube 10, and the upper end negative pressure drainage part 301 thereof will smoothly extend into the patient's recto-vaginal fistula 4000.

[0110] In this way, a negative pressure aspirator 5000 can be connected to the lower end of the recto-vaginal fistula negative pressure suction tube 30 to suck out the residual fluid in the patient's recto-vaginal fistula 4000, so as to facilitate the rapid healing of the patient's recto-vaginal fistula 4000. In this process, the inflated first airbag 101 is used to block the secretions that may flow out of the patient's vagina 2000, the inflated second airbag 102 is used to block the residual fluid that may be sucked by negative pressure at the opening of the patient's vagina 2000, and the inflated third airbag 201 is used to block The stool that may flow out of the patient's rectum 3000, the inflated fourth airbag 202 is used to block the residual liquid that may be sucked into the stoma of the patient's rectum 3000 by negative pressure, so that the patient's recto-vaginal fistula 4000 after the residual liquid is sucked out by negative pressure can be fully sealed, so that the patient's vagina 2000 urine, residual liquid at the vaginal opening, rectal stool and residual liquid from the stoma are not easy to enter the patient's recto-vaginal fistula 4000, so that the patient's recto-vaginal fistula 4000 can indeed remain dry and sterile for a certain period of time, so as to achieve rapid healing and repair.

[0111] Furthermore, the present application is indeed highly practical and reliable to use, resulting in good use effects.

[0112] Accordingly, the overall structure of the present invention is simple, easy to implement, easy to operate, highly specific, and has a low manufacturing cost, which makes the present invention inevitably have a good market promotion value. The present invention will be very popular and can be effectively popularized.
