Description

Technical Field

[0001] The present invention belongs to the technical field of medical auxiliary equipment, and in particular relates to a stoma measuring device and a stoma replacement device. Background Art

[0002] A stoma is a surgical procedure performed to separate the intestines and bring one end of the intestine to the surface of the body (from the anus or urethra to the abdominal wall) due to digestive or urinary system diseases. A stoma is typically performed for rectal or bladder diseases (such as rectal cancer, bladder cancer, and intestinal obstruction). To save the patient's life, the doctor surgically removes the diseased area. For example, for rectal cancer, the rectum and anal canal are removed, and for bladder cancer, the bladder is removed. Then, an opening is created on the left or right side of the patient's abdomen.

[0003] Stoma bags are essential medical devices for daily use by stoma patients. They collect ostomy excreta (feces or urine), and changing ostomy bags is an essential step in stoma care. Currently, stoma bag changes require accurate stoma measurements. The size and shape of the stoma base are measured, and then the center hole of the base is cut to size. Ideally, the center hole should be approximately 1-2 mm larger than the stoma base. Cutting too large may expose too much skin, which can easily cause excreta leakage, while cutting too small may cause friction with the intestinal mucosa at the stoma, causing bleeding and pain.

[0004] However, due to different surgical methods, the shape of the stoma may be circular, elliptical or irregular. For example, an end stoma (single-lumen stoma) has only one opening in the abdominal wall, so its stoma shape is single-opening, mostly circular or elliptical. Another example is a loop stoma (double-lumen stoma), which has two openings in the abdominal wall, so its shape is irregular, specifically approximately "∞" shape. In the prior art, when measuring a stoma, a measuring ruler or a soft tape is often used for auxiliary measurement, which makes it difficult to ensure measurement accuracy. There are also some stoma measuring devices, but it is difficult to accurately measure a loop stoma in actual use. For example, the Chinese invention patent with publication number CN110108181B proposes a stoma measuring device, which uses multiple slides in conjunction with a water pen to achieve the cutting position drawn on the lower surface of the stoma bag chassis, and then cut the stoma bag chassis. However, in actual use, multiple water pens are used to determine the positions of multiple cutting points on the bottom plate of the ostomy bag (the end point of the line drawn by the water pen is the position of the cutting point). For the irregular stoma shape of the loop stoma, multiple points are completely unable to meet the cutting accuracy. This is mainly because the line between two adjacent cutting points needs to be supplemented by medical staff based on visual inspection. For example, the Chinese invention patent with publication number CN118687445B proposes a stoma measurement device, which has a measuring structure. When measuring the stoma, after the inner wall is roughly fitted to the outer wall of the stoma and the side fixing column is locked, the user drives the force transmission column to apply pressure to the base ring or the telescopic ring through the push plate, causing the corresponding position of the base ring or the telescopic ring to produce a shape change that fits the outer wall of the stoma. Obviously, it also fits the outer wall of the stoma at multiple points (i.e., the contact points between the connector and the stoma). The telescopic ring and the base ring between two adjacent connectors proposed in it cannot guarantee that they fit the stoma, especially for the stoma shape of the loop stoma that is approximately "∞", and it cannot perform accurate measurement. Summary of the Invention

[0005] In view of the above problems, the purpose of the present invention is to provide a stoma measurement device and a stoma replacement device.

[0006] The technical solution of the present invention is: a stoma measuring device, including a base, a top plate, a support rod group and a measuring component. The base is a ring-shaped structure, which is used to be placed on the stoma wound, and the stoma wound is located within the ring of the base. The top plate is parallel to the base and opposite to each other, and a cutting piece is provided on the side of the top plate close to the base. The support rod group includes a plurality of support rods and a connecting ring, the lower ends of the plurality of support rods are all slidably arranged on the base along the axis of the base, and the upper ends of the support rods are all slidably arranged on the top plate along the axis of the base; a plurality of perforations are provided on the connecting ring, and the plurality of perforations correspond one-to-one to the plurality of support rods, and the support rods pass through the perforations. The measuring component includes a pen holder, a push rod, a measuring rod, a contact rod and a cutting rod. The pen barrel is arranged parallel to the bottom surface of the top plate and is set between any two adjacent support rods; the push rod is arranged coaxially with the pen barrel, passes through the pen barrel and is slidably set inside the pen barrel; the measuring rod is fixed on the push rod and is vertically distributed between the base and the top plate; the contact rod is arranged at one end of the measuring rod close to the base, and the contact rod has a contact end, which is used to contact the stoma; the cutting rod is arranged at one end of the measuring rod close to the top plate, and the cutting rod has a cutting end, which corresponds to the position of the contact end and is used to cut the cutting piece.

[0007] In actual use, the stoma is positioned by the inner ring, and the annular structure of the base directly covers the four sides of the stoma. One hand presses the top plate to ensure that the base will not shift when the measuring component is in use. The other hand applies thrust to the push rod so that the contact end of the contact rod contacts the root of the stoma. The push rod is rotated circumferentially along the axis of the base. During the rotation, the contact end of the contact rod is always in contact with the root of the stoma. During this process, the contact end rotates in a circle along the same horizontal line along the root of the stoma, and the cutting end corresponding to the position of the contact end walks on the cutting piece and cuts the circumference corresponding to the shape of the stoma root.

[0008] Furthermore, an elastic member is provided in the pen barrel, and a chuck is provided on the side wall of the push rod located inside the pen barrel, and the chuck is slidably provided inside the pen barrel; one end of the elastic member is clamped on the side of the pen barrel near the center of the base ring, and the other end is clamped on the chuck. The clamping and sliding structure of the chuck and the elastic member ensures that the compression of the elastic member is linearly corresponding to the displacement of the push rod. On the one hand, the sliding limit of the chuck inside the pen barrel can accurately control the force application range of the contact rod to avoid excessive pressure on the stoma tissue; on the other hand, when the elastic member is in the initial uncompressed state, the chuck is located inside the pen barrel and is at the farthest position from the stoma position. At this time, the contact end is also at the farthest position from the stoma position. In actual use, due to the different shapes of stomas, the elastic member can effectively ensure that the contact end is at the initial farthest position from the stoma, thereby ensuring that it can be effectively used for stomas of various shapes.

[0009] Furthermore, one end of the measuring rod is perpendicularly positioned at the end of the push rod near the center of the base ring. This arrangement, perpendicular to the axis of the push rod and in conjunction with its orthogonal structure with the contact rod, allows for simultaneous acquisition of two-dimensional X and Y data on the stoma diameter. This significantly reduces spatial coordinate errors compared to measurements made with oblique arrangements.

[0010] Furthermore, the contact rod is perpendicular to the measuring rod, with one end positioned at the end of the measuring rod closest to the base and the contact end at the other end. A ball bearing is mounted on the contact end. Compared to traditional flat contact, the rolling friction coefficient between the ball bearing and the stoma tissue significantly reduces mechanical irritation to the wound during measurement.

[0011] Furthermore, the cutting rod is parallel to the contact rod, and the cutting rod is slidingly set on the end of the measuring rod close to the top plate and fixed by bolts. The cutting end is located at the end of the cutting rod corresponding to the position of the ball. The cutting rod remains parallel to the contact rod. When the ball of the contact rod contacts the stoma, the cutting end of the cutting rod automatically aligns with the cutting piece on the top plate, realizing the "measurement-positioning-cutting" three-in-one operation, which is 70% more efficient than the traditional step-by-step operation. The corresponding positions of the cutting end and the ball form a "binocular positioning" system. The movement trajectory of the ball of the contact rod on the stoma surface can directly affect the cutting path of the cutting piece. Compared with the traditional visual cutting and point cutting methods, the positioning error is effectively reduced.

[0012] Furthermore, the effective length of the cutting rod on the side of the measuring rod close to the base ring center is L, and the effective total length of the contact rod and the ball is H, which is 1~2mm longer than L. Since the cutting size of the center hole of the ostomy bag base should be 1-2mm larger than the stoma root, this length is used as the effective length for cutting and contact, so that the pattern cut by the cutting end corresponding to the contact end is exactly the pattern required to be cut out of the ostomy bag base.

[0013] Furthermore, the top plate includes a mounting ring and a mounting plate. The mounting ring corresponds to the position of the base, and the end of the support rod is slidably mounted on the mounting ring. The mounting plate is structured to match the inner ring of the mounting ring and is movably mounted on the inner ring of the mounting ring. Multiple rotating knobs are evenly arranged on the edge of the lower surface of the mounting plate, and the edges of the cut pieces are engaged with the rotating knobs. The mounting plate is movably mounted on the inner ring of the mounting ring, making it easy to remove during use. Before use, the mounting plate is removed from the inner ring of the mounting ring, the edge of the new cut piece is engaged with the rotating knobs, and the mounting plate is re-installed on the inner ring of the mounting ring.

[0014] Furthermore, the mounting ring has a first thread on its inner ring wall, and the mounting plate has a second thread on its outer side that matches the first thread. The mounting plate is threaded on the mounting ring, and the thickness ratio of the mounting plate to the mounting ring is 1.5 to 2:1. In actual use, the mounting plate's threaded adjustment process can be used to adjust the actual horizontal height of the mounting plate, so that the cutting piece located below the mounting plate can be better matched with the cutting end.

[0015] Furthermore, the stoma measurement device also includes a handheld portion having a clamping structure and a first clamping end and a second clamping end. The base is disposed on the first clamping end, and the top plate is disposed on the second clamping end. The lower end of the support rod has a T-shaped structure. The base is provided with a first annular groove having a T-shaped longitudinal cross-section, and the lower end of the support rod is clamped into the first annular groove. The lower end of the mounting ring is provided with a second annular groove having an inverted V-shaped longitudinal cross-section. When the handheld portion is in the clamping position, the upper end of the support rod slides into the second annular groove. This makes it more convenient in actual use, allowing medical personnel to hold the handheld portion with one hand and operate the push rod with the other hand. Furthermore, the support rod is clamped into the first annular groove on the base, so that the support rod and the base form an integral structure and move with the first clamping end. The second clamping end controls the movement of the top plate. When the handle is in the extreme clamping position, the top plate and the base are exactly parallel, and the upper end of the support rod slides into the second annular groove. The second annular groove has an inverted V-shaped longitudinal cross-section to facilitate the upper end of the support rod's release from the second annular groove when the handle is opened.

[0016] A stoma replacement device uses the stoma measuring device to measure the stoma wound, and the cutting piece is paper or a leak-proof patch: when the cutting piece is paper, the cutting end is a single blade head, which is used to compare and cut the stoma bag base after cutting; when the cutting piece is a leak-proof patch, the cutting end is a double blade head.

[0017] Working method of the present invention: Compared with the prior art, the present invention has the following beneficial effects: The stoma measuring device of the present invention obtains the correspondence between the contact end and the cutting end position of the cutting rod based on the contact rod, and cuts the cutting piece into a shape corresponding to the shape of the stoma root based on the measurement of the outer contour of the stoma root. Compared with the use of a multi-point method to determine the outer contour of the stoma root, the present invention constructs the cutting pattern completely according to the outer contour of the stoma root, and obviously has higher measurement accuracy.

[0018] In addition, the stoma replacement device of the present invention is based on a stoma measuring device, which can not only realize the cutting size of the ostomy bag base according to the outer contour of the stoma root, but also the actual size of the anti-leakage patch according to the outer contour of the stoma root. It has high measurement accuracy in actual use, so that the cut ostomy bag base and anti-leakage patch can perfectly match the outer contour of the root, which can effectively avoid the occurrence of skin complications around the stoma.

They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed or operate in a specific orientation, and therefore should not be construed as limiting the present invention.

[0022] The terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include one or more of such features; in the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0023] Example 1 like Figure 1 、 Figure 2 A stoma measuring device shown includes a base 1, a top plate 2, a support rod group 3 and a measuring assembly 4. The base 1 is a ring-shaped structure, which is used to be placed on the stoma wound, and the stoma wound is located within the ring of the base 1. The top plate 2 is parallel to the base 1 and is positioned opposite to each other. A cutting piece 20 is provided on the side of the top plate 2 close to the base 1. The support rod group 3 includes a plurality of support rods 31 and a connecting ring 32. The lower ends of the plurality of support rods 31 are all slidably arranged on the base 1 along the axis of the base 1, and the upper ends of the support rods 31 are all slidably arranged on the top plate 2 along the axis of the base 1; the connecting ring 32 is provided with a plurality of through-holes, and the plurality of through-holes correspond one-to-one to the plurality of support rods 31, and the support rods 31 pass through the through-holes. The measuring assembly 4 includes a pen holder 41, a push rod 42, a measuring rod 43, a contact rod 44 and a cutting rod 45. The pen holder 41 is arranged parallel to the bottom surface of the top plate 2 and is set between any two adjacent support rods 31; the push rod 42 is arranged coaxially with the pen holder 41, passes through the pen holder 41 and is slidably set in the pen holder 41; the measuring rod 43 is fixed on the push rod 42, and is vertically distributed between the base 1 and the top plate 2; the contact rod 44 is arranged at the end of the measuring rod 43 close to the base 1, and the contact rod 44 has a contact end, which is used to contact the stoma; the cutting rod 45 is arranged at the end of the measuring rod 43 close to the top plate 2, and the cutting rod 45 has a cutting end, which corresponds to the position of the contact end and is used to cut the cutting piece 20.

[0024] In actual use, the stoma is positioned by the inner ring, and the annular structure of the base 1 directly covers the four sides of the stoma. One hand presses the top plate 2 to ensure that the base 1 does not shift when the measuring component 4 is in use. The other hand applies a thrust to the push rod 42 so that the contact end of the contact rod 44 contacts the root of the stoma. The push rod 42 is rotated circumferentially along the axis of the base 1. During the rotation, the contact end of the contact rod 44 always contacts the root of the stoma. During this process, the contact end rotates in a circle along the same horizontal line along the root of the stoma, and the cutting end corresponding to the position of the contact end moves on the cutting piece 20 to a shape corresponding to the shape of the stoma root.

[0025] It should be noted that: the cutting piece of the present embodiment is paper, and the cutting end is a cutter head. The cutting end cuts out a pattern corresponding to the shape of the stoma root on the cutting piece, and then the pattern corresponding to the shape of the stoma root is placed on the ostomy bag chassis, and cutting is carried out along the cutting pattern. In addition, the cutting end can also be a pen. If the cutting end is a pen, then a pattern corresponding to the shape of the stoma root is drawn on the cutting piece. Moreover, the cutting piece can also be an ostomy bag chassis, and the ostomy bag chassis is fixed on the top plate 2. If the cutting end is a pen, then a pattern corresponding to the shape of the stoma root is drawn on the ostomy bag chassis. If the cutting end is a cutter head, then a pattern corresponding to the shape of the stoma root is directly cut out on the ostomy bag chassis.

[0026] Preferably, Figure 3 As shown, an elastic member 410 is provided in the pen barrel 41, and a chuck 420 is provided on the side wall of the push rod 42 located inside the pen barrel 41. The chuck 420 is slidably provided inside the pen barrel 41; one end of the elastic member 410 is clamped on the side of the pen barrel 41 close to the center of the base 1, and the other end is clamped on the chuck 420. Figure 3 As shown, in this embodiment, the elastic member 410 is a spring. The engaging and sliding structure of the chuck 420 and the elastic member 410 ensures that the compression of the elastic member 410 is linearly proportional to the displacement of the push rod 42. On the one hand, the sliding limit of the chuck 420 within the pen barrel 41 can accurately control the force application range of the contact rod 44 to avoid excessive pressure on the stoma tissue. On the other hand, when the elastic member 410 is in its initial uncompressed state, the chuck 420 is located inside the pen barrel 41 and is at its farthest position from the stoma. At this time, the contact end is also at its farthest position from the stoma. In actual use, since stomas vary in shape, the elastic member 410 can effectively ensure that the contact end is initially at its farthest position from the stoma, thereby ensuring effective use for stomas of various shapes.

[0027] Preferably, one end of the measuring rod 43 is perpendicularly arranged at the end of the push rod 42 near the center of the ring of the base 1. The measuring rod 43 is arranged perpendicular to the axis of the push rod 42. Combined with its orthogonal structure with the contact rod 44, it can simultaneously obtain two-dimensional data of the stoma diameter along the X and Y axes. Compared with the measurement method of the oblique arrangement, its spatial coordinate error can be effectively reduced.

[0028] Preferably, the contact rod 44 is perpendicular to the measuring rod 43, one end of the contact rod 44 is arranged at the end of the measuring rod 43 close to the seat 1, and the contact end is located at the other end of the contact rod 44, and a ball is provided on the contact end. The ball in this embodiment is made of Φ2mm medical-grade stainless steel. Compared with traditional plane contact, the rolling friction coefficient between the ball at the contact end and the stoma tissue greatly reduces the mechanical stimulation to the wound during measurement, which is particularly suitable for patients in the fragile healing period of 3-7 days after surgery. In addition, the gap between the ball and the contact rod 44 adopts a 0.2mm narrow slit design to prevent soft tissues such as intestinal mucosa from being embedded, and at the same time, the contact end is chamfered to R0.1mm to avoid mechanical damage.

[0029] Preferably, the cutting rod 45 is parallel to the contact rod 44. The cutting rod 45 is slidably arranged on the end of the measuring rod 43 close to the top plate 2 and fixed by a bolt 450. The cutting end is located at the end of the cutting rod 45 corresponding to the position of the ball. The cutting rod 45 remains parallel to the contact rod 44. When the ball of the contact rod 44 contacts the stoma, the cutting end of the cutting rod 45 automatically aligns with the cutting piece 20 of the top plate 2, realizing the "measurement-positioning-cutting" three-in-one operation, which is 70% more efficient than the traditional step-by-step operation. The corresponding positions of the cutting end and the ball form a "binocular positioning" system. The movement trajectory of the ball of the contact rod 44 on the stoma surface can directly affect the cutting path of the cutting piece 20. Compared with the traditional visual cutting and point cutting methods, the positioning error is effectively reduced.

[0030] Preferably, the effective length of the cutting rod 45 on the side of the measuring rod 43 near the center of the base 1 is L, and the effective total length of the contact rod 44 and the ball is H, where H is 1-2 mm longer than L. Because the cutting size of the center hole of the ostomy bag base should be 1-2 mm larger than the root of the stoma, this length serves as the effective cutting and contact length, ensuring that the cutting end corresponding to the contact end cuts the pattern exactly as required by the ostomy bag base.

[0031] Preferably, Figure 4 、 Figure 5 As shown, the top plate 2 includes a mounting ring 21 and a mounting plate 22. The mounting ring 21 corresponds to the position of the base 1, and the end of the support rod 31 is slidably mounted on the mounting ring 21. The structure of the mounting plate 22 matches the inner ring of the mounting ring 21 and is movably mounted on the inner ring of the mounting ring 21. A plurality of rotating knobs 220 are evenly arranged on the edge of the lower surface of the mounting plate 22, and the edges of the cutting piece 20 are snapped into the rotating knobs 220. The mounting plate 22 is movably mounted on the inner ring of the mounting ring 21, making it easy to disassemble during use. Before use, the mounting plate 22 is removed from the inner ring of the mounting ring 21, and the edge of the new cutting piece 20 is snapped into the rotating knobs 220, and the mounting plate 22 is re-set on the inner ring of the mounting ring 21.

[0032] It should be noted that in this embodiment, the mounting plate 22 is a cylindrical structure with a circular bottom. A socket is provided at the center of the circle, and a securing pin is inserted into the socket. After the cutting piece 20 is placed on the bottom of the mounting plate 22 and engaged by rotating the locking knob 220, the securing pin secures the cutting piece 20 at its center. This further secures the cutting piece 20, preventing gravity from affecting the cutting process. The securing pin further prevents the cutting piece 20 from falling off the bottom of the mounting plate 22. Other measures to prevent the cutting piece 20 from falling can also be adopted, but these are not detailed here.

[0033] Preferably, the inner wall of the mounting ring 21 is provided with a first thread, and the outer side of the mounting plate 22 is provided with a second thread that matches the first thread. The mounting plate 22 is threaded onto the mounting ring 21, and the thickness ratio of the mounting plate 22 to the mounting ring 21 is 1.5 to 2:1. In actual use, the actual horizontal height of the mounting plate 22 can be adjusted by adjusting the thread adjustment process of the mounting plate 22, so that the cutting piece 20 located below the mounting plate 22 can be better matched with the cutting end.

[0034] Example 2 The difference from Example 1 is that: Preferably, Figure 6 As shown, the stoma measurement device also includes a handheld portion 5, which has a clamp structure. The handheld portion 5 has a first clamping end 51 and a second clamping end 52. The base 1 is arranged on the first clamping end 51, and the top plate 2 is arranged on the second clamping end 52; the lower end of the support rod 31 is a T-shaped structure, and the base 1 is provided with a first annular groove with a T-shaped longitudinal section, and the lower end of the support rod 31 is clamped in the first annular groove; the lower end of the mounting ring 21 is provided with a second annular groove, and the longitudinal section of the second annular groove is an inverted V-shaped structure. When the handheld portion 5 is in a clamping state, the upper end of the support rod 31 is slidably arranged in the second annular groove.

[0035] In actual use, it is more convenient. Medical staff can hold the handheld part 5 with one hand and operate the push rod 42 with the other hand. Among them, the support rod 31 is clamped in the first annular groove on the base 1, so that the support rod 31 and the base 1 are an integral structure and move with the first clamping end 51. The second clamping end 52 is used to control the movement of the top plate 2. When the handheld part 5 is in the extreme position of the clamping state, the top plate 2 and the base 1 are exactly parallel. At this time, the upper end of the support rod 31 is slidably arranged in the second annular groove. Among them, the longitudinal section of the second annular groove is an inverted V-shaped structure so that when the upper end of the support rod 31 is separated from the second annular groove, that is, when the handheld part 5 is opened, the upper end of the support rod 31 can be more easily disengaged from the second annular groove. It should be noted that: in order for the lower end and the upper end of the support rod 31 to slide effectively in the first annular groove and the second annular groove, the lower end and the upper end of the support rod 31 are both provided with sliding wheels or sliding balls to reduce friction.

[0036] Example 3 A stoma replacement device uses the stoma measurement device proposed in Example 2 to measure the stoma wound, and the cutting piece 20 is paper or a leak-proof patch: like Figure 3 As shown, when the cutting piece 20 is paper, the cutting end is a single blade head, which is used to perform control cutting on the ostomy bag chassis after cutting.

[0037] like Figure 7 As shown, when the cutting piece 20 is a leak-proof sticker, the cutting end is a double-headed cutter. It should be noted that when the cutting end is a double-headed cutter, the position of the cutter head closest to the center of the ring of the base 1 corresponds to the position of the contact end, and the distance between the double cutter heads is the width of the required leak-proof sticker. The leak-proof sticker finally cut out is a regular or irregular ring structure.

[0038] It should be noted that the cutting end of this embodiment can be detachably mounted on the cutting rod 45 .

[0039] The method of using this embodiment is: Before use, remove the mounting plate 22 from the inner ring of the mounting ring 21, clip the edge of the paper into the rotating button 220, and re-install the mounting plate 22 on the inner ring of the mounting ring 21. During use, hold the handle 5 with one hand, position the stoma through the inner ring, and directly cover the stoma with the annular structure of the base 1. Ensure that pressure is applied to the top plate 2 to ensure that the base 1 does not shift during use of the measuring component 4. Use the other hand to apply a thrust to the push rod 42 so that the contact end of the contact rod 44 contacts the stoma root. Rotate the push rod 42 circumferentially along the axis of the base 1. During the rotation, the contact end of the contact rod 44 always contacts the stoma root. During this process, the contact end rotates in a circle along the same horizontal line along the stoma root. The cutting end corresponding to the position of the contact end moves on the cutting piece 20 to cut the circumference corresponding to the shape of the stoma root, thereby obtaining the cut pattern paper. Remove the cut pattern paper, cut the corresponding size on the ostomy bag base according to the pattern paper, and use your fingers to round off the burrs left after cutting.

[0040] Then remove the mounting plate 22 from the inner ring of the mounting ring 21 and snap the edge of the leak-proof patch into the rotating knob 220. The initial shape of the leak-proof patch now corresponds to the cross-section of the mounting plate 22, which in this embodiment is a round pancake-shaped structure. Reinstall the mounting plate 22 on the inner ring of the mounting ring 21. Replace the single blade on the cutting end with a double blade and repeat the above steps to cut the leak-proof patch to obtain the trimmed leak-proof patch.

[0041] It should be noted that: since the thickness of paper is inconsistent with the thickness of the anti-leakage sticker, the height of the rotating button 220 in this embodiment is adjustable. Specifically, the rotating button 220 is fixed to the lower surface of the mounting plate 22 by a bolt. The distance between the rotating button 220 and the lower surface of the mounting plate 22 is adjusted by adjusting the actual number of thread turns of the bolt to achieve clamping of paper and anti-leakage stickers of different thicknesses.

[0042] In addition, the steps of the above-mentioned method of use can also be directly cut once, that is, the leak-proof patch is cut, and finally the corresponding size is cut on the ostomy bag chassis according to the inner ring shape of the cut leak-proof patch.

[0043] The specific embodiments described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above are only specific embodiments of the present invention and do not limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are included in the scope of protection of the present invention.
