Description

Technical Field

[0001] The invention relates to the technical field of anorectal drug delivery devices, in particular to an anal surgery postoperative rehabilitation auxiliary equipment. Background Art

[0002] After perianal surgery, the wound and anus need to be cleaned regularly. You can use Chinese medicine flushing or sitz bathing to achieve therapeutic effects such as reducing swelling and pain, promoting blood circulation and removing blood stasis, which is beneficial to postoperative recovery.

[0003] When washing the anus after surgery, a syringe can be used to extract the liquid for washing. Because there will be one or more wounds in the anus after anal fistula surgery, which are open and sunken wounds, local washing of the wound can effectively reduce the residue of feces and other pollutants. When washing perianal surgery, since the wound has not yet healed, the resistance to excrement pollution is poor. When washing, the perianal wound should be carefully washed. In addition, the inner end of the anus close to the perianal wound should also be washed to prevent the secretions of the perianal wound from infiltrating into the anus and flowing out after washing the perianal area, causing fecal contamination. For the washing of the anus of patients after perianal surgery, the existing irrigators or enema devices are not completely applicable, because they do not consider whether the patient has a wound around the anus. When placed in the anus, the secretions of the perianal wound may be sent into the anus, which may cause the risk of rectal infection. In addition, the position to be washed by patients after perianal surgery is the perianal wound and the inner end of the anus, not enema washing, so more dedicated washing equipment is currently needed in clinical practice. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an anal surgery postoperative rehabilitation auxiliary device in view of the above-mentioned technical deficiencies, which can perform liquid flushing on the perianal wound surface and the anal end to prevent cross infection.

[0005] The technical solution adopted by the present invention is: to provide an anal surgery postoperative rehabilitation auxiliary device, comprising a push tube, which is configured to inject a flushing liquid into the inner end of the anus; the entry end of the push tube is provided with a pointed portion whose maximum outer diameter is larger than the outer diameter of the push tube; the side wall of the area where the pointed portion and the push tube are connected is uniformly provided with first liquid outlet holes in the circumferential direction; the end of the push tube is provided with a flushing liquid pipeline joint; The positioning flushing cover is configured to provide a guide and positioning for the push tube; the opening end surface of the positioning flushing cover is an ergonomic concave arc surface; a drainage joint for discharging the flushing liquid is provided on the positioning flushing cover; a guide tube for guiding the push tube and the pointed part is provided in the middle of the positioning flushing cover; A rotary isolation diaphragm is constructed to isolate the direct contact and sliding friction between the push tube and the anus; the rotary isolation diaphragm is a tubular elastic soft membrane structure with one end sealed; one end of the rotary isolation diaphragm seal passes through the top through hole of the pointed head and is placed inside the push tube; the rotary isolation diaphragm located outside the push tube is folded over and wrapped around the pointed head and the outside of the push tube; a first positioning retaining ring is provided at the outer end of the rotary isolation diaphragm; the first positioning retaining ring is positioned and matched with the outer port of the guide tube of the positioning flushing cover; a second liquid outlet hole is opened on the side wall of the rotary isolation diaphragm, and when one end of the rotary isolation diaphragm seal is completely folded over and wrapped around the pointed head and the outside of the push tube from the inside of the push tube, the second liquid outlet hole and the first liquid outlet hole are connected.

[0006] To further optimize the technical solution, drainage grooves for discharging the flushing liquid are evenly distributed on the concave arc surface of the positioning flushing cover.

[0007] To further optimize the technical solution, the inner wall of the push tube is slidably fitted with a piston, and the top end of the piston is fixedly connected to the sealing end of the rotary isolation diaphragm.

[0008] To further optimize the technical solution, an isolation tube is coaxially arranged inside the push tube, the upper end of the isolation tube is sealed and connected to the upper end of the inner wall of the pointed part, and the top through hole of the pointed part is connected to the isolation tube; the lower end of the isolation tube is sealed so that one end of the rotary isolation diaphragm seal is isolated from the inner cavity of the push tube.

[0009] To further optimize the technical solution, the rotary isolation membrane is made of polyurethane, and its side wall is evenly mixed with shaped fibers in the circumferential direction, and the layout direction of the shaped fibers is the length direction of the rotary isolation membrane.

[0010] To further optimize the technical solution, a second positioning retaining ring 16 is provided on the outer wall of the push tube; the push tube is pushed into the anus, and when one end of the rotary isolation membrane seal is completely folded over the pointed end and the outside of the push tube from the inside of the push tube, the second retaining ring reaches the first retaining ring, and at this time, the first retaining ring and the second retaining ring are both limited by the outer port of the guide tube.

[0011] The technical solution adopted in the present application is that the push tube does not directly contact the perianal area and the inner wall of the anus, but is isolated from the contact by a rotating isolation membrane. The function of the push tube is to enter the inner end of the anus and introduce flushing solution to flush the inner end of the anus outward; the function of the rotating isolation membrane is to isolate the push tube from direct contact with the inner wall of the anus, and enter the anus in a way that the inner wall of the tube is folded outward to be sent out, without sliding friction with the perianal area and the inner wall of the anus, and will not send perianal secretions into the anus.

[0012] When the part of the rotary isolation membrane located inside the push tube is completely folded to the outside, that is, the rotary isolation membrane is completely sleeved on the outside of the push tube, the position of the push tube at the end inside the anus is locked; at this time, the channel between the second liquid outlet and the first liquid outlet is connected, and the flushing liquid can be injected into the anus from the push tube; the maximum outer diameter of the pointed part is larger than the outer diameter of the push tube, and its contact pressure relative to the inner wall of the anus is larger than that of the push tube, so the flushing liquid will not flow inward over the pointed part, but will flow along the outer wall of the rotary isolation membrane to flush the inner wall of the end inside the anus.

[0013] After the anus is rinsed clean, the push tube and rotating isolation membrane can be withdrawn from the anus, the positioning flushing cover can be removed, and the anus can be flushed with liquid medicine or fumigated in a sitz bath. When the end of the anus is rinsed clean, there is no need to worry about cross infection.

[0014] Other technical effects of the present invention will become clearer as the embodiments are described. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Example 1

[0018] like Figure 1 , Figure 2 As shown, an auxiliary device for postoperative rehabilitation of anal surgery, comprising A push tube 1 is configured to inject a flushing liquid into the anal end; the entry end of the push tube 1 is provided with a pointed portion 2 whose maximum outer diameter is larger than the outer diameter of the push tube 1; the side wall of the pointed portion 2 and the push tube 1 in the docking area is uniformly provided with first liquid outlet holes 3 in the circumferential direction; the end of the push tube 1 is provided with a flushing liquid pipeline connector 4; The positioning flushing cover 5 is configured to provide guidance and positioning for the push tube 1; the opening end surface of the positioning flushing cover 5 is an ergonomic concave arc surface 6; the positioning flushing cover 5 is provided with a drainage joint 7 for discharging the flushing liquid; the middle part of the positioning flushing cover 5 is provided with a guide tube 8 for guiding the push tube 1 and the pointed part 2; The rotary isolation diaphragm 9 is constructed to isolate the direct contact and sliding friction between the push tube 1 and the anus; the rotary isolation diaphragm 9 is a tubular elastic soft membrane structure with one end sealed; the sealed end of the rotary isolation diaphragm 9 passes through the top through hole of the pointed part 2 and is placed inside the push tube 1; the rotary isolation diaphragm 9 located outside the push tube 1 is folded and wrapped around the pointed part 2 and the outside of the push tube 1; the outer end of the rotary isolation diaphragm 9 is provided with a first positioning retaining ring 10; the first positioning retaining ring 10 is positioned and matched with the outer port of the guide tube 8 of the positioning flushing cover 5; the side wall of the rotary isolation diaphragm 9 is opened with a second liquid outlet 11, and when the sealed end of the rotary isolation diaphragm 9 is completely folded from the inside of the push tube 1 to cover the pointed part 2 and the outside of the push tube 1, the second liquid outlet 11 and the first liquid outlet 3 are connected.

[0019] The function of the first positioning retaining ring 10 is to limit the rotation isolation membrane 9 through the positioning flushing cover 5. When the push tube 1 enters the anus, the rotation isolation membrane 9 is blocked by the positioning flushing cover 5 and will not slide relative to the inner wall of the anus. It can only be released by folding outward from the top through hole of the pointed part 2 through the part located in the push tube 1. The liquid flushed out from the end of the anus is collected by the positioning flushing cover 5 and flows out from the drainage joint 7.

[0020] To further optimize this embodiment, the concave arc surface 6 of the positioning flushing cover 5 is evenly distributed with drainage grooves 12 for discharging the flushing liquid. After the end of the anus is rinsed clean by the liquid medicine, it can continue to be rinsed. For example, the compound phellodendron lotion and the compound sophora flavescens lotion can promote blood stasis and swelling, clear away heat, dry dampness and relieve itching, and enhance the local blood circulation around the anus. After the flushed Chinese medicine liquid is gathered by the positioning flushing cover 5, the drainage joint 7 or the external drainage hose connected to it can be cut off or blocked, so that the Chinese medicine liquid will overflow from the drainage groove 12 after the positioning flushing cover 5 is full. This process is accompanied by immersion and flushing of the perianal wound surface, so that both the flushing of the end of the anus and the flushing of the perianal wound surface can be completed, simplifying the operation steps. Example 2

[0021] like Figure 3 , Figure 4As shown, the difference between this embodiment and embodiment 1 is that a piston 13 is slidably fitted on the inner wall of the push tube 1 , and the top end of the piston 13 is fixedly connected to the sealing end of the rotary isolation diaphragm 9 .

[0022] The function of the piston 13 is to isolate the flushing liquid after it moves to the top of the first liquid outlet 3, so as to prevent the flushing liquid from entering the rotating isolation membrane 9 from the top through hole of the pointed part 2, thereby reducing the discomfort of the patient. In addition, when the push tube 1 is withdrawn, the rotating isolation membrane 9 can be brought out in a folded inward manner under the drive of the piston 13, thereby reducing the friction on the inner wall of the anus. Example 3

[0023] like Figure 5 , Figure 6 As shown, the difference between this embodiment and embodiment 1 is that an isolation tube 14 is coaxially arranged inside the push tube 1, the upper end of the isolation tube 14 is sealed and connected to the upper end of the inner wall of the pointed part 2, and the top through hole of the pointed part 2 is connected to the isolation tube 14; the lower end of the isolation tube 14 is sealed so that the sealed end of the rotating isolation membrane 9 is isolated from the inner cavity of the push tube 1.

[0024] The function of the isolation tube 14 is similar to that of the piston 13, both of which can prevent the flushing liquid from entering the rotating isolation membrane 9 from the top through hole of the pointed part 2, causing the rotating isolation membrane 9 to expand and pressurize above the pointed part 2. Compared with Example 2, the isolation tube 14 is simpler to set up and has lower cost.

[0025] like Figure 7 As shown, in combination with Example 2 or Example 3, a further optimized solution is that the rotary isolation membrane 9 is made of polyurethane, and its side wall is evenly mixed with shaping fibers 15 in the circumferential direction, and the layout direction of the shaping fibers 15 is the length direction of the rotary isolation membrane 9. The rotary isolation membrane 9 itself has elasticity and can be tightly wrapped around the outer wall of the push tube 1 and the pointed part 2. The surface is tensioned and smooth without wrinkles. The shaping fibers 15 can prevent the axial elastic expansion and contraction of the rotary isolation membrane 9, and further control the sliding friction of the rotary isolation membrane 9 relative to the inner wall of the anus when the push tube 1 is inserted.

[0026] Combined with the above optimization scheme, further optimization is performed: the outer wall of the push tube 1 is provided with a second positioning retaining ring 16; the push tube 1 is pushed into the anus, and when the sealed end of the rotary isolation diaphragm 9 is completely folded from the push tube 1 to cover the pointed part 2 and the outside of the push tube 1, the second retaining ring reaches the first retaining ring, and at this time, the first retaining ring and the second retaining ring are both limited by the outer port of the guide tube 8. The function of the second retaining ring is to limit the maximum depth of the push tube 1 to prevent it from breaking through the limit of the rotary isolation diaphragm 9 and causing damage to the rotary isolation diaphragm 9. In addition, its positioning is more accurate, which can overcome the inaccurate depth positioning caused by the axial expansion and contraction of the rotary isolation diaphragm 9.

[0027] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0028] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
