Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a cleaning and disinfection device for anorectal diseases. Background Technology

[0002] Colorectal surgery primarily studies the anus and surrounding tissues, as well as the colon and rectum. Hemorrhoids, anal fissures, perianal abscesses, and sacrococcygeal tumors are all considered colorectal diseases. Incisions in colorectal surgery are mainly performed inside or around the anus and rectum. Procedures such as perianal abscess incision and drainage, complex anal fistula excision, and external hemorrhoid excision require incisions in the skin around the anus. This results in intense postoperative pain and visible wounds on the skin. Therefore, postoperative care is essential in colorectal surgery. To prevent infection and worsening of the wound, regular cleaning and disinfection of the wound are necessary.

[0003] For patients whose surgical incisions are located around the anus, the contraction and expansion of the sphincter muscles during defecation can stretch the surgical wound, causing intermittent cramping or colic. Furthermore, the friction of feces against the surgical wound further exacerbates discomfort, making defecation a very painful process. Existing cleaning and disinfection devices mainly consist of sitz baths and spray rinsing. Sitz baths are less effective, and while spray rinsing can remove bacteria and excrement from the skin surface, the skin around the anus is folded, making direct spray rinsing ineffective. Therefore, medical staff often need to use medical cotton to wipe the skin during spraying, which inevitably causes discomfort, increases the difficulty of cleaning, and exacerbates patient suffering. Therefore, this invention provides a cleaning and disinfection device for proctology to meet these needs. Summary of the Invention

[0004] The technical problem this invention aims to solve is to provide a cleaning and disinfection device for proctology. By incorporating a positioning component, it can not only separately rinse and disinfect the inside and outside of the patient's anus, but also gradually and slowly support the patient's anus after the supporting balloon is inflated. This avoids friction between the cleaning tube and the wound during rinsing, reducing patient pain. The inflatable balloon also supports the internal rectal tissues, creating a more spacious cleaning and disinfection area. This facilitates subsequent softening of feces using water sprayed from the cleaning tube, improving the efficiency of fecal softening. Softened feces are easier to expel from the patient's body, avoiding significant friction between feces and the wound during defecation, further enhancing patient comfort. These features solve the current problems of intense pain and difficulty in rinsing the anus.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A cleaning and disinfection device for anorectal surgery includes an infusion pump and a cleaning tube. The cleaning tube is connected to the outlet of the infusion pump, and an outlet is provided at the end of the cleaning tube. A positioning component is also included. The positioning component is used to clean and disinfect the patient's anus. The positioning component is connected to the cleaning tube and includes a positioning cylinder and a baffle plate sleeved on the outside of the cleaning tube. The baffle plate is snapped and fixed to the bottom of the positioning cylinder.

[0006] Optionally, a support airbag is fixedly connected to the outer wall of the positioning cylinder, an inclined plate is fixedly connected to the top of the positioning cylinder, and an expansion airbag is fixedly connected to the end of the inclined plate. The inclined plate has a conical profile that is recessed toward the center of the positioning cylinder.

[0007] Optionally, a positioning plate is fixedly connected to the bottom of the positioning cylinder, and a bent portion is fixedly connected to the end of the positioning plate. A first inflation channel and a second inflation channel are provided inside both the positioning cylinder and the positioning plate.

[0008] Optionally, the first inflation channel and the second inflation channel are respectively connected to the support airbag and the expansion airbag, and the ends of the first inflation channel and the second inflation channel are respectively fixedly connected to a first inflation tube and a second inflation tube, and a press-type inflation valve is provided in both the first inflation tube and the second inflation tube.

[0009] Optionally, the positioning plate has a downwardly recessed arc-shaped profile, the bending portion has a "C"-shaped profile, and the positioning cylinder, the positioning plate, and the bending portion are integrally manufactured.

[0010] Optionally, the top of the baffle plate is fixedly connected to an adapter plate that matches the contour of the positioning plate, and the end of the adapter plate is fixedly connected to a snap-fit ​​plate that matches the contour of the bent portion. The baffle plate, the adapter plate, and the snap-fit ​​plate are integrally manufactured.

[0011] Optionally, the baffle plate has an outwardly convex arc-shaped profile at the middle position, the baffle plate is enclosed to form a funnel-shaped structure, and the bottom of the baffle plate is a tubular structure adapted to the size of the cleaning pipe.

[0012] Optionally, a plurality of locking plates are fixedly connected to the bottom of the baffle plate, and there is a gap between the plurality of locking plates. A locking sleeve is screwed onto the bottom outer wall of the baffle plate.

[0013] Optionally, the bottom outer wall of the locking plate is a sloping structure, and the size of the bottom outer wall of the locking plate is larger than the size of its top outer wall, and the bottom inner wall of the locking sleeve is a sloping structure with the same inclination angle as the outer wall of the locking plate.

[0014] Optionally, a sealing ring is installed between the bottom inner wall of the baffle plate and the outer wall of the cleaning pipe.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, by setting up a positioning component, not only can the inside and outside of the patient's anus be rinsed and disinfected separately, but also, when rinsing the inside of the patient's anus, the inflating of the support balloon can gradually and slowly support the patient's anus, thereby avoiding friction between the cleaning tube and the wound during the rinsing process, reducing the patient's pain during the rinsing process. After the expansion balloon is inflated, it can support the tissue inside the patient's rectum, presenting a more open cleaning and disinfection space, which facilitates the subsequent softening of feces with the water sprayed from the cleaning tube, improving the efficiency of fecal softening. The softened feces are easier to expel from the patient's body, avoiding greater friction between the feces and the wound during the patient's defecation process, further improving the patient's comfort.

[0016] By incorporating a support airbag and a baffle plate within the positioning component, the support airbag, after inflation, possesses a certain degree of deformation capability, preventing excessive tearing sensation when the patient's anus is opened. This ensures patient comfort near the anus while simultaneously supporting it. Furthermore, the inflated support airbag adheres closely to the patient's skin, preventing wastewater from leaking out of the gap between the positioning cylinder and the anus during the rinsing and disinfection process, thus maintaining a clean and hygienic cleaning environment. Wastewater generated throughout the cleaning process is collected within the baffle plate. This baffle plate not only prevents wastewater splashing during rinsing and disinfection but also allows for unified collection of wastewater, facilitating subsequent wastewater treatment by medical staff and improving the cleanliness and efficiency of the surgery.

[0017] By incorporating an adapter plate and a snap-fit ​​plate within the positioning assembly, the adapter plate can fit tightly against the positioning plate due to their matching contours. The "C"-shaped bend further encloses and limits the snap-fit ​​plate. The combined effect of the adapter plate, positioning plate, snap-fit ​​plate, and bend allows the baffle plate and positioning cylinder to engage. Once engaged, the bottom of the positioning cylinder is sealed by the baffle plate. This snap-fit ​​method is not only structurally simple but also easy to assemble and disassemble. Furthermore, the baffle plate, locking plate, and adapter plate are manufactured as a single unit, simplifying the manufacturing process and making the product easier to produce, thus meeting actual production needs.

[0018] By setting a locking plate and a locking sleeve, when medical staff screw on the locking sleeve, the locking sleeve will squeeze the locking plate under the driving action of the thread. Under the squeezing action of the locking sleeve, the locking plate will deform towards the cleaning tube, thereby achieving the effect of clamping and fixing the cleaning tube. This design can use the baffle plate to fix the cleaning tube, saving medical staff from having to manually hold the cleaning tube all the time, and further improving the convenience of cleaning and disinfection operations.

[0023] The following is a detailed description of a cleaning and disinfection device for anorectal diseases provided by the present invention, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0024] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0025] Generally, terms can be understood at least partly from their use in context.

Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0026] It is understood that the meanings of “on”, “above”, and “above” in this invention should be interpreted in the broadest manner, such that “on” means not only “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” means not only “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0027] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings.

[0028] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a cleaning and disinfection device for anorectal surgery, including an infusion pump 1 and a cleaning tube 2. The cleaning tube 2 is connected to the outlet of the infusion pump 1, and an outlet is provided at the end of the cleaning tube 2. The infusion pump 1 is used to deliver cleaning solution and disinfectant to the cleaning tube 2. The cleaning solution and disinfectant in the cleaning tube 2 are discharged from the outlet at the end, thereby cleaning and disinfecting the patient's anus. The distance between the infusion pump 1 and the cleaning tube 2 is disclosed as prior art and will not be described in detail here. A positioning component is used to clean and disinfect the patient's anus. The positioning component is connected to the cleaning tube 2 and includes a positioning cylinder 3 and a baffle plate 13 sleeved on the outside of the cleaning tube 2. The baffle plate 13 is snapped and fixed to the bottom of the positioning cylinder 3, and an inclined plate 6 is fixedly connected to the top of the positioning cylinder 3. In the positioning component, The positioning tube 3 is mainly used to open the patient's anus, making it easier for medical staff to insert the cleaning tube 2 into the patient's anus later, avoiding excessive friction between the cleaning tube 2 and the patient's wound during insertion and improving patient comfort. The baffle plate 13 is mainly used to assist medical staff in holding and positioning the cleaning tube 2, improving the ease of operation of the cleaning tube 2, thereby improving the efficiency of the entire cleaning and disinfection work. In addition, by setting up the positioning component, the cleaning tube 2 can rinse and disinfect the inside and outside of the patient's anus. Cleaning the inside of the patient's anus can soften the patient's stool, making it easier for the patient to defecate and reducing the pain during defecation. Rinsing the outside of the patient's anus can prevent the growth of bacteria near the wound and improve the patient's postoperative safety. The positioning component can also prevent the splashing of waste liquid during the rinsing and disinfection process, improving the environmental hygiene during the cleaning and disinfection process.

[0029] As one implementation method in this embodiment, such as Figures 1 to 7As shown, a support airbag 7 is fixedly connected to the outer wall of the positioning cylinder 3, and an expansion airbag 8 is fixedly connected to the end of the inclined plate 6. The inclined plate 6 has a conical profile that is recessed towards the center of the positioning cylinder 3. A positioning plate 4 is fixedly connected to the bottom of the positioning cylinder 3. A first inflation channel 10 and a second inflation channel 12 are provided inside both the positioning cylinder 3 and the positioning plate 4. The first inflation channel 10 and the second inflation channel 12 are respectively connected to the support airbag 7 and the expansion airbag 8. A first inflation tube 9 and a second inflation tube 9 are fixedly connected to the ends of the first inflation channel 10 and the second inflation channel 12, respectively. Both the first inflation tube 9 and the second inflation tube 11 are equipped with press-type inflation valves. As mentioned above, the positioning cylinder 3 can open the patient's anus. Specifically, the positioning cylinder 3 is a small cylindrical tube. Since the inclined plate 6 at the end of the positioning cylinder 3 has a concave concave conical profile, when medical personnel insert the positioning cylinder 3 into the patient's body, they can use the conical profile of the inclined plate 6 to guide and insert it. This design makes the insertion of the positioning cylinder 3 into the patient's anus relatively smooth, and the patient's anus will not experience a large stinging sensation, thus reducing the patient's pain.

[0030] Furthermore, a support airbag 7 is also provided on the outer wall of the positioning cylinder 3. The support airbag 7 is a deflated airbag under normal conditions, and expands into a cylindrical airbag after inflation (e.g., Figure 5 and Figure 7 As shown in the diagram, the support airbag 7 gradually supports the patient's anus during the inflation process. Moreover, the support airbag 7 has a certain deformation capacity after inflation, so that the patient's anus will not experience excessive tearing sensation after being supported and opened. This ensures the patient's comfort near the anus while supporting it. Furthermore, the support airbag 7 adheres to the patient's skin after inflation, preventing sewage from the rectum from flowing out from the gap between the positioning cylinder 3 and the anus during the rinsing and disinfection process, thus ensuring a clean and hygienic cleaning environment.

[0031] In addition, an expansion airbag 8 is provided at the end of the inclined plate 6. The expansion airbag 8 is a deflated airbag in the initial state, and it is folded and stored on the inner wall of the inclined plate 6 before inflation (e.g., Figure 2 and Figure 5 As shown), the expansion airbag 8 will inflate and bulge outwards, presenting a cone-shaped profile with the opening facing outwards (as shown). Figure 7As shown in the diagram, this design allows the inflated expansion bladder 8 to support the tissues inside the patient's rectum, creating a more spacious cleaning and disinfection area. This facilitates the subsequent softening of feces using water sprayed from the cleaning tube 2, improving the efficiency of fecal softening. Furthermore, the inflated expansion bladder 8 does not come into contact with the skin near the patient's anus, preventing the wound near the anus from being pulled or torn, further improving patient comfort. In addition, the inflated expansion bladder 8 adheres to the skin of the patient's rectal wall, and together with the sealing effect of the support bladder 7 on the anus, it can further prevent wastewater from flowing out from the gap between the patient's anus and the positioning cylinder 3 during the flushing and disinfection process.

[0032] In summary, the positioning component has two usage states: State 1 (e.g., ...) Figure 5 As shown), the support airbag 7 and the expansion airbag 8 are in an uninflated state, at which time the positioning cylinder 3 can be easily and smoothly inserted into the patient's anus; State two (as shown) Figure 7 As shown), both the support airbag 7 and the expansion airbag 8 are in the inflated state. At this time, the support airbag 7 can support the skin near the patient's anus, so that the patient's anus is opened by the support airbag 7, and the skin inside the patient's rectum is stretched open by the expansion airbag 8, providing a more open space for rinsing and disinfection. Moreover, in the second state, the support airbag 7 and the expansion airbag 8 can seal the anus to prevent sewage from flowing out from the gap between the patient's anus and the positioning cylinder 3 during the rinsing and disinfection process, ensuring a clean and hygienic environment.

[0033] Optionally, in this technical solution, both the support airbag 7 and the expansion airbag 8 are made of soft rubber material, ensuring that the patient's skin will not experience excessive foreign body sensation or discomfort during the process of being stretched. The support airbag 7 and the expansion airbag 8 are inflated via the first inflation tube 9 and the second inflation tube 11, respectively. Medical personnel connect the inflation mechanism to the ends of the first inflation tube 9 and the second inflation tube 11. The gas filled in the first inflation tube 9 and the second inflation tube 11 enters the support airbag 7 and the expansion airbag 8 along the first inflation channel 10 and the second inflation channel 12, respectively. In this technical solution, the working principle of inflating the support airbag 7 and the expansion airbag 8 using the inflation mechanism is disclosed as prior art. Medical personnel can choose the specific inflation mechanism according to the actual situation, which will not be elaborated here. Since a press-type inflation valve is installed on both the first inflation tube 9 and the second inflation tube 11, it achieves a one-way sealing effect. The press-type inflation valve is disclosed as prior art in this technical solution.

[0034] Optionally, in this technical solution, the expansion airbag 8 presents a cone-shaped profile with the opening facing outward after inflation. The profile after inflation is a shape that has been predetermined during the production process of the product, and the cone-shaped profile can be automatically presented after inflation without human intervention.

[0035] To illustrate this more intuitively, the accompanying drawings in this technical solution include a simulated buttock plate 19 and a simulated anus 20, which can help in understanding how the positioning component interacts with the skin of the anus and buttocks of the human body.

[0036] In this embodiment, as Figure 2 , Figure 7 and Figure 8 As shown, the end of the positioning plate 4 is fixedly connected to a bent portion 5. The positioning plate 4 has a downwardly concave arc-shaped contour, and the bent portion 5 has a "C"-shaped contour. The positioning cylinder 3, the positioning plate 4, and the bent portion 5 are integrally manufactured. The top of the baffle plate 13 is fixedly connected to an adapter plate 15 that matches the contour of the positioning plate 4. The end of the adapter plate 15 is fixedly connected to a snap-fit ​​plate 16 that matches the contour of the bent portion 5. The middle position of the baffle plate 13 has an outwardly convex arc-shaped contour. The baffle plate 13 forms a funnel-shaped structure. The baffle plate 13, the adapter plate 15, and the snap-fit ​​plate 16 are integrally manufactured. The baffle plate 13 is snap-fitted and fixed to the bottom of the positioning cylinder 3. In actual operation, medical personnel first insert the positioning cylinder 3 into the patient's body, so that the positioning plate 4 touches the skin surface near the patient's anus, and then snap-fit ​​the baffle plate 13 to the bottom of the positioning cylinder 3. Specifically, because the positioning plate 4 and The adapter plate 15 is contoured to fit the positioning plate 4, so the adapter plate 15 can fit tightly together. Since the bent part 5 has a "C" shaped contour, it can wrap and limit the snap-fit ​​plate 16. With the combined effect of the adapter plate 15 and the positioning plate 4, as well as the snap-fit ​​plate 16 and the bent part 5, the baffle plate 13 and the positioning cylinder 3 can be snapped together. When the positioning cylinder 3 and the baffle plate 13 are snapped together, the bottom of the positioning cylinder 3 will be blocked by the baffle plate 13. The sewage flowing out of the positioning cylinder 3 during the rinsing and disinfection process will be collected in the baffle plate 13. Since the baffle plate 13 has an outwardly convex arc shape, it can collect and retain more sewage. This setting can not only prevent sewage from splashing during the rinsing and disinfection process, but also allow the baffle plate 13 to collect sewage in a unified manner, which is convenient for medical staff to treat the sewage in a unified manner later, improving the cleanliness of the operation and the efficiency of the operation.

[0037] After the patient's anus is cleaned, the medical staff can remove the positioning tube 3 and then place the baffle 13 against the skin of the patient's buttocks. At this time, the skin of the patient's anus is cleaned and disinfected with the help of the cleaning tube 2. During the rinsing process, the baffle 13 can still collect waste liquid, making the whole rinsing process cleaner and more convenient.

[0038] As one implementation method in this embodiment, such as Figure 8 and Figure 9As shown, the bottom of the baffle plate 13 is a tubular structure adapted to the size of the cleaning pipe 2. Several locking plates 14 are fixedly connected to the bottom of the baffle plate 13, with spacing between them. A locking sleeve 17 is screwed onto the outer bottom wall of the baffle plate 13. The outer bottom wall of the locking plate 14 is a sloping structure, and its size is larger than its top size. The inner bottom wall of the locking sleeve 17 is a sloping structure with the same inclination angle as the outer wall of the locking plate 14. A sealing ring 18 is installed between the inner bottom wall of the baffle plate 13 and the outer wall of the cleaning pipe 2. The cleaning pipe 2 is inserted into the baffle plate 13 from the tubular structure at its bottom. Because a sealing ring 18 is provided between the baffle plate 13 and the cleaning pipe 2... Therefore, it can be ensured that waste liquid will not leak from the bottom of the baffle plate 13 during the rinsing process. After the relative position between the cleaning tube 2 and the baffle plate 13 is determined, medical personnel can lock and fix the cleaning tube 2 by turning the locking sleeve 17. Specifically, the outer wall of the bottom of the locking plate 14 is set with a sloping structure. When the locking sleeve 17 is turned, the locking sleeve 17 will squeeze the locking plate 14 under the driving action of the thread. The locking plate 14 will deform towards the cleaning tube 2 under the squeezing action of the locking sleeve 17, thereby achieving the effect of clamping and fixing the cleaning tube 2. This design can use the fixing effect of the baffle plate 13 to save medical personnel from manually holding the cleaning tube 2 all the time, and further improve the convenience of cleaning and disinfection operation.

[0039] The working principle of the technical solution provided by this invention is as follows: In use, first apply lubricant evenly to the outer wall of the positioning cylinder 3. After sufficient lubrication, slowly insert the positioning cylinder 3 into the patient's anus. Stop pushing the positioning cylinder 3 when the positioning plate 4 fully contacts the skin on the outside of the patient's anus. At this point, the positioning cylinder 3 is fully inserted. Connect the inflation mechanism to the first inflation tube 9. After connection, inflate the air. The gas enters the support bladder 7 along the first inflation channel 10. After inflation, the support bladder 7 expands and gradually supports the patient's anus. The inflated support bladder 7 adheres to the patient's skin, preventing sewage from the rectum from flowing out from the gap between the positioning cylinder 3 and the anus during the rinsing and disinfection process, thus ensuring a clean and hygienic cleaning environment. After the support bladder 7 is fully inflated, remove the inflation mechanism from the first inflation tube 9 and reinstall it on the second inflation tube 11. Each of the first inflation tubes 9 is equipped with a press-type inflation valve. Therefore, after the inflation mechanism is removed from the first inflation tube 9, the gas in the support bladder 7 will not be discharged from the first inflation tube 9. After the inflation mechanism is installed on the second inflation tube 11, it is inflated. The gas enters the expansion bladder 8 along the second inflation channel 12. After inflation, the expansion bladder 8 expands and bulges outward, presenting a cone-shaped profile that supports the tissue inside the patient's rectum, presenting a more open cleaning and disinfection space. This facilitates the subsequent softening of feces with the water sprayed from the cleaning tube 2, improving the efficiency of fecal softening. Moreover, after inflation, the expansion bladder 8 will press against and adhere to the skin of the patient's rectal wall. Combined with the sealing effect of the support bladder 7 on the anus, it can further prevent sewage from flowing out from the gap between the patient's anus and the positioning cylinder 3 during the flushing and disinfection process.

[0040] After both the support airbag 7 and the expansion airbag 8 are fully inflated, the baffle plate 13 is snapped and fixed to the bottom of the positioning cylinder 3. Since the contours of the positioning plate 4 and the adapter plate 15 are compatible, the adapter plate 15 can fit tightly against the positioning plate 4. Since the bending part 5 has a "C" shaped contour, it can wrap and limit the snap-fit ​​plate 16. With the combined effect of the adapter plate 15 and the positioning plate 4, as well as the snap-fit ​​plate 16 and the bending part 5, the baffle plate 13 and the positioning cylinder 3 can be snapped together. When the positioning cylinder 3 and the baffle plate 13 are snapped together, the bottom of the positioning cylinder 3 will be blocked by the baffle plate 13.

[0041] After the baffle plate 13 is installed at the bottom of the positioning cylinder 3, the infusion pump 1 delivers disinfectant and cleaning solution to the cleaning tube 2. The cleaning solution and disinfectant in the cleaning tube 2 are discharged from the outlet at the end, thereby flushing away the feces in the patient's anus. During the cleaning and disinfection process, the waste liquid will flow out along the inner wall of the positioning cylinder 3 and will be collected in the baffle plate 13. Since the baffle plate 13 has an outwardly convex arc-shaped contour, it can collect and retain a large amount of sewage. This design not only prevents sewage from splashing during the rinsing and disinfection process, but also allows the baffle plate 13 to collect sewage in a unified manner, which is convenient for medical staff to treat the sewage in a unified manner later.

[0042] After the patient's anus is rinsed, the positioning tube 3 and the cleaning tube 2 are removed from the patient's body. Then, the baffle plate 13 is placed against the outside of the patient's anus. The infusion pump 1 is used to deliver disinfectant and cleaning solution to the cleaning tube 2. The cleaning tube 2 is placed on the outside of the patient's anus. The cleaning solution and disinfectant in the cleaning tube 2 are discharged from the outlet at the end. Then, the outside of the patient's anus is rinsed and disinfected. During the cleaning and disinfection process, the waste liquid is directly collected in the baffle plate 13.
