Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to an anal and rectal postoperative irrigation device. Background Art

[0002] Postoperative wound care for anorectal surgery is crucial for reducing complications and promoting healing. Due to its special anatomical location (fragile mucosa, many folds, and vulnerable to contamination), the anal area is prone to being stimulated by feces and secretions after surgery, leading to infections, pain, or delayed healing. Traditional postoperative irrigation care mostly adopts a fixed mode, such as uniformly using warm sitz baths or low-pressure irrigation, but ignores the histological characteristics and physiological needs in different stages (acute stage, healing stage, recovery stage) during the wound healing process, resulting in the following problems: Acute stage (within 1 week after surgery): In the initial stage after surgery, the wound surface shows the formation of fresh granulation tissue with inflammatory exudation, and nerve endings are exposed and sensitive. If directly using the conventional water flow intensity or close-range irrigation, the high-pressure water flow may damage the blood clot or newly formed epithelium, increasing the risk of pain and bleeding. And overly conservative low-pressure irrigation cannot effectively remove secretions, increasing the probability of infection.

[0003] Healing stage (2 - 4 weeks after surgery): During this stage, the granulation tissue gradually matures, but the capillaries are rich and the structure is loose. If continuing to use the extremely low water pressure or long-distance irrigation in the acute stage, it is difficult to thoroughly clean the residues in the deep folds; conversely, using high-pressure water flow too early may damage the granulation tissue, resulting in increased exudation or abnormal scar hyperplasia.

[0004] Recovery stage (after 4 weeks after surgery): After the formation of scar tissue, its elasticity and blood supply are worse than those of normal tissues. If still using the high-frequency drug irrigation in the healing stage, it may damage the skin barrier function, causing dryness or itching. And ignoring the adjustment of the water flow angle (such as continuous lateral irrigation) may lead to cleaning blind spots, increasing the risk of recurrence.

[0005] Existing studies have pointed out that the biological process of wound healing has clear stage characteristics (inflammatory phase, proliferative phase, remodeling phase), and the tolerance to mechanical stimulation and cleaning requirements vary significantly in different stages. However, the currently commonly used clinical irrigation devices (such as fixed water pressure irrigators, general sitz baths) lack a parameter adjustment scheme for different stages after anorectal surgery, resulting in limited nursing effects. In addition, when patients operate by themselves, due to the lack of professional guidance, secondary injuries are easily caused due to improper water flow intensity, angle, or distance.

[0006] Therefore, there is an urgent need to design an anal and rectal postoperative irrigation device to solve the above-mentioned problems. Summary of the Invention

[0007] The object of the present invention is to provide an anal and rectal postoperative irrigation device, which has the advantages of adjusting the water flow intensity, position and distance according to different periods of patients, and balancing wound surface protection and cleaning efficiency, and solves the problems mentioned in the background art.

[0008] To achieve the above object, the specific technical solution of an anal and rectal postoperative irrigation device of the present invention is as follows: An anal and rectal postoperative irrigation device includes a basin for the patient to sit in.

The flushing assembly has a first position, a second position and a third position; When the flushing assembly is in the first position, the distance between the flushing assembly and the anus is relatively far, and the inclination angle between the water flow and the anus is relatively large; When the flushing assembly is in the second position, the distance between the flushing assembly and the anus is moderate, and the inclination angle between the water flow and the anus is relatively small; When the flushing assembly is in the third position, the distance between the flushing assembly and the anus is relatively close, and the water flow is directly facing the anus; When the patient is in the acute stage, the flushing assembly is in the first position, and the water flow sprayed by the flushing assembly is in a mist shape; When the patient is in the healing stage, the flushing assembly is in the second position, and the water flow sprayed by the flushing assembly is in a gentle mixed shape; When the patient is in the recovery stage, the flushing assembly is in the third position, and the water flow sprayed by the flushing assembly is in a water column shape.

[0009] Further, the flushing assembly includes a nozzle. A sliding block is fixedly connected to the nozzle. A sliding groove is formed on the basin, and the basin is slidably connected to the sliding block through the sliding groove. The sliding groove is inclined; Further, a connecting plate is connected inside the nozzle.

One end of the first partition ring away from the connecting plate is fixedly connected to a first partition plate, and one end of the first partition plate away from the first partition ring is fixedly connected to the inner wall of the nozzle.

A mixing chamber is formed by the first partition plate, the first partition ring, the second partition plate, the second partition ring and the inner wall of the nozzle, and the mixing chamber communicates with the mixing hole group. A water column chamber is formed by the second partition plate, the second partition ring and the inner wall of the nozzle, and the water column chamber communicates with the water column hole.

[0011] Further, a sliding chamber is provided in the nozzle. A connecting pipe is provided in the sliding chamber for water flow. The connecting pipe is fixedly connected to the basin body, and the nozzle can slide relative to the connecting pipe. The connecting pipe is provided with discharge holes. The sliding chamber is provided with a first through hole, a second through hole and a third through hole. The first through hole communicates with the atomizing chamber, the second through hole communicates with the mixing chamber, and the third through hole communicates with the water column chamber; When the flushing assembly is in the first position, the discharge hole coincides with the first through hole, and the connecting pipe communicates with the atomizing chamber. The water flow is ejected from the atomizing hole group through the connecting pipe and the atomizing chamber; When the flushing assembly is in the second position, the discharge hole coincides with the second through hole, and the connecting pipe communicates with the mixing chamber. The water flow is ejected from the mixing hole group through the connecting pipe and the mixing chamber; When the flushing assembly is in the third position, the discharge hole coincides with the third through hole, and the connecting pipe communicates with the water column chamber. The water flow is ejected from the water column hole through the connecting pipe and the water column chamber.

[0012] Further, the basin body includes an upper basin and a lower basin. The upper basin is for the patient to sit on. The upper basin and the lower basin are detachably connected, and the upper basin can slide relative to the lower basin. A third partition plate is fixedly connected to the lower basin. The bottom of the upper basin, the third partition plate and the lower basin form a cleaning chamber for placing cleaning liquid. A communicating pipe is provided on the basin wall of the upper basin. One end of the communicating pipe communicates with the cleaning chamber, and the other end of the communicating pipe away from the cleaning chamber communicates with the connecting pipe. After the patient sits on the upper basin, the upper basin moves downward toward the lower basin, and the cleaning liquid in the lower basin is pressured and transported to the nozzle through the communicating pipe and the connecting pipe.

[0014] Furthermore, the edge of the upper basin, the third partition board, and the lower basin form an isolation cavity, and the auxiliary component is arranged in the isolation cavity.

[0015] Furthermore, the auxiliary component includes two auxiliary plates. The two auxiliary plates can rotate away from or towards each other. The two auxiliary plates abut against the outer sides of the patient's legs. A toothless gear is connected to any one of the auxiliary plates. The toothless gear rotates synchronously with the auxiliary plate. The toothless gear meshes intermittently with a rack. The rack slides intermittently.

[0019] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Those skilled in the art can understand that although some embodiments herein include some features included in other embodiments rather than other features, the combination of features of different embodiments means within the scope of the present invention and forms different embodiments. For example, in the claims, any one of the claimed embodiments can be used in any combination.

[0021] The following refers to the attached Figure 1 to the attached Figure 8 to describe an anorectal postoperative irrigation device of the present invention.

[0022] Acute stage (within 1 week after surgery): In the initial stage after surgery, the wound surface shows the formation of fresh granulation tissue with inflammatory exudation, and the nerve endings are exposed and sensitive. If directly using the conventional water flow intensity or close-range irrigation, the high-pressure water flow may damage the blood clot or newly formed epithelium, increasing the risk of pain and bleeding. And the overly conservative low-pressure irrigation cannot effectively remove the secretions, increasing the probability of infection.

[0023] Healing stage (2 - 4 weeks after surgery): In this stage, the granulation tissue gradually matures, but the capillaries are rich and the structure is loose. If continuing to use the extremely low water pressure or long-distance irrigation in the acute stage, it is difficult to thoroughly clean the residues in the deep folds; on the contrary, using high-pressure water flow too early may damage the granulation tissue, resulting in increased exudate or abnormal scar hyperplasia.

[0024] Recovery period (after 4 weeks post - operation): After scar tissue forms, its elasticity and blood supply are poorer than normal tissues. If high - frequency drug flushing used in the healing period is still adopted, it may damage the skin barrier function, causing dryness or itching. Ignoring the adjustment of the water flow angle (such as continuous lateral flushing) may lead to cleaning blind spots and increase the risk of recurrence.

[0025] Currently, commonly used flushing devices in clinical practice (such as fixed - water - pressure flushing devices and general sitz baths) lack a parameter - adjustment plan for different stages after anorectal surgery, resulting in limited nursing effects. In addition, when patients operate by themselves, due to the lack of professional guidance, secondary injuries are likely to be caused by improper water flow intensity, angle or distance.

[0026] Therefore, this anorectal postoperative flushing device includes a basin body 1 for the patient to sit in. Inside the basin body 1, there is a flushing component, which can flush the patient's anus. The flushing component has a first position, a second position and a third position; When the flushing component is in the first position, the distance between the flushing component and the anus is relatively far, and the inclination angle between the water flow and the anus is relatively large; specifically, the distance between the flushing component and the anus is relatively far, about 15 - 20 cm, to avoid the water flow directly impacting the wound. The inclination angle between the water flow and the anus is relatively large, and the water flow flushes obliquely from the side of the anus, avoiding directly facing the center of the anus, reducing the vertical pressure on the wound surface.

[0027] When the flushing component is in the second position, the distance between the flushing component and the anus is moderate, and the inclination angle between the water flow and the anus is relatively small; specifically, the distance between the flushing component and the anus is moderate, about 10 - 15 cm, appropriately increasing the water flow contact area. The inclination angle between the water flow and the anus is relatively small, meaning the water flow can slightly face the anus to more thoroughly clean the wound surface.

[0028] When the flushing component is in the third position, the distance between the flushing component and the anus is relatively close, and the water flow faces the anus directly; specifically, the distance between the flushing component and the anus is relatively close, about 5 - 10 cm, and the water flow direction can face the anus directly to more efficiently clean the anal folds and prevent dirt accumulation.

[0029] When the patient is in the acute stage, the flushing component is in the first position, and the water flow sprayed by the flushing component is in a misty state; specifically, the water flow sprayed by the flushing component is in a misty state, allowing the water flow to evenly disperse and cover the perianal area, rather than concentrating at one point, reducing the mechanical stimulation of the water flow on the fragile wound surface and cleaning secretions at the same time.

[0030] When the patient is in the healing period, the flushing component is in the second position, and the water flow sprayed by the flushing component is in a gentle mixed state. Specifically, the water flow sprayed by the flushing component is in a gentle mixed state, taking into account both cleaning power and comfort; When the patient is in the recovery period, the flushing component is in the third position, and the water flow sprayed by the flushing component is in a water - column state. The concentrated water flow can more efficiently clean the anal folds.

[0031] When the patient is in the acute stage, the distance between the flushing component and the anus is relatively far, the inclination angle between the water flow and the anus is relatively large, and the water flow sprayed by the flushing component is in a mist shape to protect the newly formed tissue, avoid high-pressure water flow from washing away the newly formed blood clot or newly formed granulation tissue, resulting in bleeding or delayed healing, reduce the patient's pain at the same time, avoid directly stimulating the wound nerve endings due to excessive water flow pressure, aggravating postoperative pain, and avoid the risk of infection. Strong water flow may wash the perianal bacteria into the deep layer of the wound surface, increasing the probability of infection.

[0032] When the patient is in the healing stage, the distance between the flushing component and the anus is moderate, the inclination angle between the water flow and the anus is relatively small, and the water flow sprayed by the flushing component is in a gentle mixed state to thoroughly clean the secretions. Moderate water flow can more effectively remove the remaining necrotic tissue or secretions, reduce the risk of infection, promote local circulation at the same time. Moderate water flow pressure can improve the blood circulation around the wound surface, accelerate tissue repair, and adapt to the healing process. The tolerance of the newly formed granulation tissue is enhanced, but high pressure still needs to be avoided to prevent rupture of tiny blood vessels.

[0033] When the patient is in the recovery period, the distance between the flushing component and the anus is relatively close, the water flow is directly facing the anus, and the water flow sprayed by the flushing component is in a water column shape to maintain the cleaning efficiency. Normal water flow can more efficiently clean the anal folds, prevent dirt residue and recurrence, promote scar softening at the same time. Moderate water flow massage can improve the blood circulation in the scar area, reduce the sense of stiffness, and restore physiological functions, gradually adapting to the normal cleaning intensity to help the patient return to daily life.

[0034] Specifically, the flushing component includes a nozzle 3. A sliding block 4 is fixedly connected to the nozzle 3. A chute 41 is formed on the basin body 1. The basin body 1 is slidably connected to the sliding block 4 through the chute 41, and the chute 41 is inclined. When the flushing component slides to the first position, the distance between the flushing component and the anus is relatively far at this time, and the inclination angle between the water flow and the anus is relatively large. When the flushing component slides to the second position, the distance between the flushing component and the anus is moderate at this time, and the inclination angle between the water flow and the anus is relatively small. When the flushing component slides to the third position, the distance between the flushing component and the anus is relatively close at this time, and the water flow is directly facing the anus.

[0035] Specifically, a connecting plate 32 is connected inside the nozzle 3. An atomizing hole group 321, a mixing hole group 322 and a water column hole 323 are respectively formed on the connecting plate 32. The atomizing hole group 321 and the mixing hole group 322 are circular rings, and the mixing hole group 322 is located between the atomizing hole group 321 and the water column hole 323. When the water flow is ejected from the atomization hole group 321, the water flow ejected from the nozzle 3 is in a misty state; the atomization holes in the atomization hole group 321 are extremely fine holes (with a diameter of about 0.1 - 0.3 mm).

[0036] When the water flow is ejected from the mixing hole group 322, the water flow ejected from the nozzle 3 is in a gentle mixing state; the mixing holes in the mixing hole group 322 are fine holes, and the diameter of the mixing holes is larger than that of the atomization holes.

[0037] When the water flow is ejected from the water column hole 323, the water flow ejected from the nozzle 3 is in a water column state; the diameter of the water column hole 323 is larger than that of the mixing holes.

[0038] Regarding how the water flow is ejected from the atomization hole group 321 or the mixing hole group 322 or the water column hole 323 and is in a misty state or a gentle mixing state or a water column state, this part is all prior art, so the present invention will not elaborate here.

[0039] A first partition ring 33 and a second partition ring 34 are connected to the connecting plate 32. The first partition ring 33 is located between the atomization hole group 321 and the mixing hole group 322, and the second partition ring 34 is located between the mixing hole group 322 and the water column hole 323. One end of the first partition ring 33 far from the connecting plate 32 is fixedly connected to a first partition plate 37. One end of the first partition plate 37 far from the first partition ring 33 is fixedly connected to the inner wall of the nozzle 3. An atomization cavity 332 is formed by the first partition plate 37, the first partition ring 33 and the inner wall of the nozzle 3, and the atomization cavity 332 communicates with the atomization hole group 321. A second partition plate 36 is fixedly connected to the second partition ring 34. One end of the second partition plate 36 far from the second partition ring 34 is fixedly connected to the inner wall of the nozzle 3. A mixing cavity 331 is formed by the first partition plate 37, the first partition ring 33, the second partition plate 36, the second partition ring 34 and the inner wall of the nozzle 3, and the mixing cavity 331 communicates with the mixing hole group 322. A water column cavity 341 is formed by the second partition plate 36, the second partition ring 34 and the inner wall of the nozzle 3, and the water column cavity 341 communicates with the water column hole 323.

[0040] A sliding cavity 31 is formed in the nozzle 3. A connecting pipe 5 is arranged in the sliding cavity 31 for the water flow to flow through. The connecting pipe 5 is fixedly connected to the basin body 1. The nozzle 3 can slide relative to the connecting pipe 5. A discharge hole 51 is formed in the connecting pipe 5. A first through hole 311, a second through hole 312 and a third through hole 313 are formed in the sliding cavity 31. The first through hole 311 communicates with the atomization cavity 332, the second through hole 312 communicates with the mixing cavity 331, and the third through hole 313 communicates with the water column cavity 341; When the flushing assembly is in the first position, the discharge hole 51 coincides with the first through hole 311, and the connecting pipe 5 communicates with the atomization cavity 332. The water flow is ejected from the atomization hole group 321 through the connecting pipe 5 and the atomization cavity 332; When the flushing assembly is in the second position, the discharge hole 51 coincides with the second through hole 312, the connecting pipe 5 communicates with the mixing chamber 331, and the water flow is ejected from the mixing hole group 322 through the connecting pipe 5 and the mixing chamber 331; When the flushing assembly is in the third position, the discharge hole 51 coincides with the third through hole 313, the connecting pipe 5 communicates with the water column chamber 341, and the water flow is ejected from the water column hole 323 through the connecting pipe 5 and the water column chamber 341.

[0041] The end of the nozzle 3 is fixed by a baffle to ensure the sealing of the water column chamber 341.

[0042] The basin body 1 includes an upper basin 11 and a lower basin 12. The upper basin 11 is for the patient to sit on. The upper basin 11 and the lower basin 12 are detachably connected. The upper basin 11 can slide relative to the lower basin 12. A third partition 15 is fixedly connected to the lower basin 12. The bottom of the upper basin 11, the third partition 15 and the lower basin 12 form a cleaning chamber 14 for placing the cleaning liquid. A communicating pipe is provided on the basin wall of the upper basin 11. One end of the communicating pipe communicates with the cleaning chamber 14, and the other end of the communicating pipe away from the cleaning chamber 14 communicates with the connecting pipe 5. After the patient sits on the upper basin 11, the upper basin 11 moves downward toward the lower basin 12, and the cleaning liquid in the lower basin 12 is pressed to be transported to the nozzle 3 through the communicating pipe and the connecting pipe 5. The basin edge of the upper basin 11, the third partition 15 and the lower basin 12 form an isolation chamber 13, and the auxiliary assembly 2 is arranged in the isolation chamber 13.

[0043] After the patient sits down, the upper basin 11 presses downward to force the cleaning liquid to enter the connecting pipe 5 through the communicating pipe, realizing automatic liquid supply.

[0044] A pressure regulating valve is added at the connection of the connecting pipe and the communicating pipe to limit the water pressure in the connecting pipe within a certain range. The pressure regulating valve is a prior art.

[0045] After the anorectal surgery of the patient, when the legs are separated, the abduction of the hip joint may indirectly pull the muscles and soft tissues around the anus, increasing the wound surface tension and stimulating the nerve endings to cause pain. At the same time, the postoperative pain reflexively causes the perianal muscles (such as the external anal sphincter) to spasm, resulting in difficulty in actively separating the legs. Therefore, the angle between the legs of the patient in the acute stage is smaller, the angle between the legs of the patient in the healing stage is moderate, and the angle between the legs of the patient in the recovery stage is larger.

[0046] An auxiliary assembly 2 is provided on the basin body 1. The auxiliary assembly 2 abuts against the outer side of the patient's legs and controls the backward moving distance of the auxiliary assembly 2 according to the separation angle of the patient's legs. The auxiliary assembly 2 has a first state, a second state and a third state; When the patient is in the acute stage, the auxiliary assembly 2 is in the first state, and the flushing assembly is in the first position. Specifically, the first state is that the legs of the patient are separated by 15° - 30°, so as to preferentially protect the wound and avoid forced leg separation; When the patient is in the healing stage, the auxiliary component 2 is in the second state, and the flushing component is in the second position. Specifically, in the second state, the patient's legs are separated by 30° - 45°, the patient's pain is reduced, and it gradually expands to 30° - 45°. It cooperates with the sitz bath basin to support the buttocks, disperse the pressure, and improve the cleaning quality. When the patient is in the recovery stage, the auxiliary component 2 is in the third state, and the flushing component is in the third position. Specifically, in the third state, the patient's legs are separated by more than 45°. At this time, the wound surface of the patient is basically healed, and the cleaning quality can be further improved.

[0047] Furthermore, the auxiliary component 2 includes two auxiliary plates 21. The two auxiliary plates 21 can rotate away from or towards each other. The two auxiliary plates 21 abut against the outer sides of the patient's legs. A toothless gear 24 is connected to any one of the auxiliary plates 21. The toothless gear 24 rotates synchronously with the auxiliary plate 21. The toothless gear 24 meshes intermittently with a rack 25. The rack 25 slides with clearance. A chute is formed on the isolation cavity 13. The chute on the isolation cavity 13 is slidably connected to the rack 25. The rack 25 is fixedly connected to the flushing component. The toothless gear 24 includes a first tooth, a second tooth, and a third tooth. When the first tooth meshes with the rack 25 to drive the rack 25 to move, the auxiliary component 2 enters the first state. When the first tooth disengages from the rack 25 and the rack 25 does not mesh with the second tooth, the auxiliary component 2 is also in the first state at this time, ensuring that when the patient's legs are separated by 15° - 30°, the auxiliary component 2 is always in the first state. When the second tooth meshes with the rack 25 to drive the rack 25 to move, the auxiliary component 2 enters the second state. When the second tooth disengages from the rack 25 and the rack 25 does not mesh with the third tooth, the auxiliary component 2 is also in the second state at this time, ensuring that when the patient's legs are separated by 30° - 45°, the auxiliary component 2 is always in the second state. When the third tooth meshes with the rack 25 to drive the rack 25 to move, the auxiliary component 2 enters the third state. When the third tooth disengages from the rack 25 and the toothless gear 24 still rotates in the same direction, the auxiliary component 2 is also in the third state at this time, ensuring that when the patient's legs are separated by more than 45°, the auxiliary component 2 is always in the third state.

[0048] The first tooth, the second tooth, and the third tooth are evenly distributed and arranged in an array at the same angle. The interval angle between the first tooth, the second tooth, and the third tooth can be set according to the actual situation.

[0049] Two auxiliary plates 21 are respectively fixedly connected with gears 22. The two gears 22 are meshed with each other. The two gears 22 are respectively fixedly connected with rotating rods 23. The rotating rods 23 are rotationally connected with the lower basin 12. The missing-tooth gear 24 is fixedly connected to any one of the rotating rods 23. By setting the two gears 22 to be meshed, the rotation angles of the two auxiliary plates 21 are the same, and the rotation angle of the auxiliary plate 21 is based on the larger angle.

[0050] The patient sits into the upper basin 11, and the upper basin 11 presses down. The cleaning liquid enters the connecting pipe 5 through the connecting pipe. At this time, the discharge hole 51 is not communicated with any through holes, so the flushing assembly will not drain water at this time.
