[0003] The applicant of the present invention has found that the prior art has at least the following technical problems:

[0004] Most of the existing auxiliary devices for colonoscopy examination use an airbag structure to assist in intestinal dilation. However, when dealing with patients with anal sphincter relaxation, due to the inability of the sphincter to effectively contract, there is a gap between the anus and the inflated airbag device, and gas is likely to leak from the gap, making it difficult to ensure the sealing effect, and the intestine cannot maintain a sufficient inflated state, and it is impossible to clearly obtain the details of the intestinal wall.

[0005] In addition, there are differences in the degree of sphincter relaxation among different patients. The existing airbag structure is difficult to adapt to individual differences, resulting in unstable sealing effects, limited adaptability, and the use of the airbag structure is complex and requires high professionalism.

[0006] In view of this, the present invention is specifically proposed. Summary of the Invention

[0028] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation manners obtained by those of ordinary skill in the art without creative efforts shall fall within the scope protected by the present invention.

[0029] The present invention provides an auxiliary device for colonoscopy examination, including a patch body and a pasting part arranged on the patch body. The patch body can completely cover the anal area, and the pasting part is used to form a relatively airtight space between the patch body and the anus; an endoscope insertion hole is arranged on the patch body, and the endoscope insertion hole is slidably and hermetically connected with the colonoscope; the pasting part includes a first pasting component which is a spiral closed structure and is arranged around the endoscope insertion hole; a first filling protrusion is arranged on the pasting surface of the first pasting component corresponding to the position of the gluteal groove.

[0030] Through the synergistic effect of the patch body, the pasting part and the endoscope insertion hole, the patch body can completely cover the anal area, and the first pasting component enhances the adhesion between the patch body and the skin around the anus, so as to form a relatively airtight space between the patch body and the anus, improve the sealing effect, and the setting of the first filling protrusion better adapts to the curve of the gluteal groove, further enhancing the sealing effect, effectively preventing gas leakage during colonoscopy examination. The overall structure is simple and reasonable in design, without directly contacting the patient's anus, nor a complex airbag structure, which not only reduces costs, but also can adapt to the body types and sphincter relaxation degrees of different patients, providing a more reliable, convenient and comfortable auxiliary device for colonoscopy examination, and having a wide range of applications.

[0031] Furthermore, the first pasting component is made of a medical adhesive material and can be formed into a spiral structure through a mold. The first filling protrusion is integrally formed on the pasting surface of the first pasting group, which can better adapt to the curve of the gluteal groove and further enhance the sealing effect.

[0032] The first adhesive component with a spiral structure not only enhances the adhesion between the patch body and the skin around the anus, improving the sealing effect, but also forms a complex and long spiral gas channel inside it. When gas leakage occurs at the anus, the gas channel can guide the leaked gas to flow along a specific, non-linear path, helping to slow down the speed of the gas directly leaking into the external environment. At the same time, it provides enough time for the colonoscope to redistribute the gas in the intestine through continuous gas injection to maintain the inflated state of the intestine.

[0033] As an alternative embodiment, the shape of the first filling protrusion includes a hemispherical column shape, a semi-elliptical column shape, or a triangular column shape with smooth transitions at the corners, and both the diameter and height of the first filling protrusion gradually decrease along the direction away from the endoscope insertion hole.

[0034] Furthermore, the materials of the first adhesive component and the first filling protrusion are made of medical polyurethane adhesive, which has good elasticity and deformation ability, can better adapt to the curves of the gluteal grooves of different patients, further enhance the sealing effect, and at the same time, has strong adhesiveness and can closely adhere to the skin. Such a setting enables the patch body to always maintain a stable sealing effect during colonoscopy.

[0035] When the shape of the first filling protrusion is a triangular column shape, its two side faces are recessed inward to form arc surfaces to increase the contact area with the skin and better fit the curve of the skin.

[0036] The first filling protrusions are mainly arranged on the lower part of each circle of the first adhesive component, that is, the position close to the gluteal groove, to better adapt to the curve of the gluteal groove and make the patch body closely adhere to the skin. In the upper area of each circle of the first adhesive component close to the waist, the human curve is relatively flat, and the number of the first filling protrusions can be correspondingly reduced or omitted.

[0037] As an alternative embodiment, the adhesive part further includes a second adhesive component, which is arranged in a ring outside the first adhesive component and is a ring-shaped closed structure.

[0038] Furthermore, the second adhesive component is made of medical adhesive material and can be formed into a ring-shaped closed structure through a mold to provide an additional sealing layer and further enhance the sealing effect.

[0039] Since the gluteal groove area is a part of the human body with large curve changes, a single adhesive layer is difficult to fully adapt to the shape of this area, resulting in poor sealing effect. However, through the synergistic effect of the specific first adhesive component and the second adhesive component in the present invention, a relatively airtight space is formed between the patch body and the anus.

[0040] As an optional implementation manner, second filling protrusions are arranged on the pasting surface of the second pasting component corresponding to the position of the gluteal fold. The shapes of the second filling protrusions include hemispherical columnar, semi-elliptical columnar or triangular columnar with smooth transitions at the corners, and the diameters and heights of the second filling protrusions gradually decrease in the direction away from the endoscope insertion hole.

[0041] Furthermore, the materials of the second pasting component and the second filling protrusions are made of medical polyurethane adhesive and are integrally formed, so that they have good elasticity and deformation ability, can better adapt to the curves of the gluteal folds of different patients, further enhance the sealing effect, and at the same time, also have strong adhesiveness and can closely adhere to the skin. Such a setting enables the patch body to always maintain a stable sealing effect during the colonoscopy examination.

[0042] When the shape of the second filling protrusion is triangular columnar, arc-shaped surfaces are formed by inward depressions on both sides thereof to increase the contact area with the skin and better fit the curve of the skin.

[0043] As an optional implementation manner, the pasting part further includes a third pasting component, which is arranged on the periphery of the patch body and has a notch corresponding to the position of the gluteal fold.

[0044] Furthermore, the third pasting component is made of medical adhesive materials such as medical polyurethane adhesive and can be formed by a mold to make the connection between the patch body and the skin more stable.

[0045] The setting of the notch enables the lower part of the third pasting component to be divided into two parts, which can be respectively pasted to the corresponding thighs, improving the connection stability and reliability between the patch body and the patient.

[0046] As an optional implementation manner, an elastic sealing ring is arranged in the endoscope insertion hole, and a lubricant is coated on the sealing ring.

[0047] Furthermore, the sealing ring is made of elastic materials such as medical silicone, and the lubricant is made of medical-grade silicone oil.

[0048] The endoscope insertion hole is slightly larger than the outer diameter of the colonoscope, and the inner diameter of the sealing ring is slightly smaller than the outer diameter of the colonoscope. The sealing ring can closely fit the colonoscope to form a sliding seal connection to prevent gas from leaking through the endoscope insertion hole.

[0049] The setting of the lubricant reduces the frictional resistance when the colonoscope passes through the endoscope insertion hole and improves the smoothness of the operation.

[0050] As an optional implementation manner, an indication mark is arranged on the non-pasting surface of the patch body, and the indication mark is arranged corresponding to the central axis of the first filling protrusion.

[0051] Further, the indicating mark is made of fluorescence or a contrasting color and is printed on the non - sticking surface of the patch body, along the central axes of the first filling protrusion and the second filling protrusion, so as to facilitate doctors to visually, quickly, and accurately identify and locate the positions of the first filling protrusion and the second filling protrusion, and improve the operation efficiency.

[0052] As an alternative implementation, it further includes a pressure sensor and a one - way exhaust valve. The pressure sensor and the one - way exhaust valve are arranged in the first pasting component. The pressure sensor is used to monitor the gas pressure in the space. When the gas pressure in the space reaches a preset value, the one - way exhaust valve opens to release the excess gas and prevent over - expansion.

[0053] As an alternative implementation, the shape of the patch body includes a teardrop shape, with its small - head end extending to the coccyx region and its large - head end extending to the gluteal fold region.

[0054] Further, the patch body can be made of medical silicone or flexible plastic to make it have good flexibility and conformability.

[0055] Such a setting conforms to the ergonomic characteristics, can better adapt to the anal area, and improves the conformability and comfort.

[0056] Example 1:

[0057] As Figure 1 - Figure 2 shown, the present invention provides an auxiliary device for colonoscopy examination, including a patch body 1 and a pasting part arranged on the patch body 1. The patch body 1 can completely cover the anal area, and the pasting part is used to form a relatively airtight space between the patch body 1 and the anus; an endoscope insertion hole 11 is arranged on the patch body 1, and the endoscope insertion hole 11 is slidably and hermetically connected with the colonoscope; the pasting part includes a first pasting component 2 which is a spiral closed - type structure and is arranged around the endoscope insertion hole 11; a first filling protrusion 21 is arranged at the position corresponding to the gluteal fold on the pasting surface of the first pasting component 2.

[0058] Through the synergistic effect of the patch body 1, the pasting part and the endoscope insertion hole 11, the patch body 1 can completely cover the anal area. The first pasting component 2 enhances the conformability between the patch body 1 and the skin around the anus, so as to form a relatively airtight space between the patch body 1 and the anus, improve the sealing effect. And the setting of the first filling protrusion 21 better adapts to the curve of the gluteal fold, further enhances the sealing effect, effectively prevents gas leakage during the colonoscopy examination. The overall structure is simple and reasonably designed. It does not need to directly contact the patient's anus, nor does it need a complex airbag structure. It not only reduces costs, but also can adapt to the body types and sphincter relaxation degrees of different patients, providing a more reliable, convenient and comfortable auxiliary device for colonoscopy examination, with a wide range of applications.

[0059] Furthermore, the first adhesive component 2 is made of medical viscose material and can be formed into a spiral structure through mold forming. The first filling protrusion 21 is integrally formed on the adhesive surface of the first adhesive group, which can better adapt to the curve of the gluteal groove and further enhance the sealing effect.

[0060] The first adhesive component 2 with a spiral structure not only enhances the fit between the patch body 1 and the skin around the anus and improves the sealing effect, but also forms a complex and long spiral gas channel inside it. When gas leakage occurs at the anus, the gas channel can guide the leaked gas to flow along a specific, non-linear path, which helps to slow down the speed of gas leakage directly to the external environment. At the same time, it provides enough time for the colonoscope to redistribute the gas in the intestine through continuous gas injection to maintain the expansion state of the intestine.

[0061] As an optional implementation, the shape of the first filling protrusion 21 includes a hemispherical cylinder, a semi-elliptical cylinder, or a triangular cylinder with smoothly rounded corners, and the diameter and height of the first filling protrusion 21 gradually decrease in the direction away from the lens insertion hole 11.

[0062] Furthermore, the material of the first adhesive component 2 and the first filling protrusion 21 is medical polyurethane adhesive, which has good elasticity and deformation ability, can better adapt to the curve of the gluteal groove of different patients, further enhance the sealing effect, and at the same time, has strong adhesiveness and can fit closely with the skin. In this way, the patch body 1 can always maintain a stable sealing effect during the colonoscopy.

[0063] When the first filling protrusion 21 is in the shape of a triangular prism, both sides thereof are concave inwards to form arc-shaped surfaces, so as to increase the contact area with the skin and better fit the curve of the skin.

[0064] The first filling protrusions 21 are mainly arranged on the lower part of each circle of the first adhesive component 2, that is, near the gluteal groove, to better adapt to the curve of the gluteal groove, so that the patch body 1 fits tightly with the skin. In the upper area of ​​each circle of the first adhesive component 2 near the waist, the human body curve changes less, and the number of the first filling protrusions 21 can be reduced or omitted accordingly.

[0065] As an optional implementation, the adhesive portion further includes a second adhesive component 3, which is arranged outside the first adhesive component 2 and is an annular closed structure.

[0066] Furthermore, the second adhesive component 3 is made of medical viscose material and can be formed into an annular closed structure through mold molding, providing an additional sealing layer to further enhance the sealing effect.

[0067] Since the gluteal fold area is a part of the human body with large curve changes, a single adhesive layer is difficult to fully adapt to the shape of this area, resulting in poor sealing effect. However, through the synergistic effect of the specific first adhesive component 2 and second adhesive component 3 of the present invention, a relatively airtight space is formed between the patch body 1 and the anus.

[0068] As an optional implementation manner, the adhesive part further includes a third adhesive component 4. The third adhesive component 4 is arranged on the periphery of the patch body 1, and a notch 41 is provided corresponding to the position of the gluteal fold.

[0069] Furthermore, the third adhesive component 4 is made of a medical adhesive material such as medical polyurethane adhesive and can be formed by a mold, so that the connection between the patch body 1 and the skin is more stable.

[0070] The setting of the notch 41 enables the lower part of the third adhesive component 4 to be divided into two parts, which can be respectively pasted to the corresponding thighs, improving the connection stability and reliability between the patch body 1 and the skin.

[0071] As an optional implementation manner, an elastic sealing ring 12 is arranged in the endoscope insertion hole 11, and a lubricant is coated on the sealing ring 12.

[0072] Furthermore, the sealing ring 12 is made of an elastic material such as medical silicone, and the lubricant is a medical-grade silicone oil.

[0073] The endoscope insertion hole 11 is slightly larger than the outer diameter of the colonoscope, and the inner diameter of the sealing ring 12 is slightly smaller than the outer diameter of the colonoscope. The sealing ring 12 can closely fit the colonoscope to form a sliding seal connection, preventing gas from leaking through the endoscope insertion hole 11.

[0074] The setting of the lubricant reduces the frictional resistance when the colonoscope passes through the endoscope insertion hole 11 and improves the smoothness of the operation.

[0075] As an optional implementation manner, an indication mark 13 is arranged on the non-adhesive surface of the patch body 1, and the indication mark 13 is set corresponding to the central axis of the first filling protrusion 21.

[0076] Furthermore, the indication mark 13 is made of fluorescence or a contrasting color and is printed on the non-adhesive surface of the patch body 1 to mark the central axes of the first filling protrusion and the second filling protrusion 31, so as to facilitate doctors to visually, quickly, and accurately identify and locate the positions of the first filling protrusion 21 and the second filling protrusion 31 and improve the operation efficiency.

[0077] As an optional implementation manner, it further includes a pressure sensor 5 and a one-way exhaust valve 6. The pressure sensor 5 and the one-way exhaust valve 6 are arranged in the first adhesive component 2. The pressure sensor 5 is used to monitor the gas pressure in the space. When the gas pressure in the space reaches a preset value, the one-way exhaust valve 6 opens to release the excess gas and prevent over-expansion.

[0078] As an optional implementation manner, the shape of the patch body 1 includes a teardrop shape, with its small head end extending to the coccyx region and its large head end extending to the gluteal fold region.

[0079] Furthermore, the patch body 1 can be made of medical silicone or flexible plastic to make it have good flexibility and conformability.

[0080] With such a setting, it conforms to the ergonomic characteristics, can better adapt to the anal region, and improves the conformability and comfort.

[0081] Embodiment 2:

[0082] The difference between this Embodiment 2 and Embodiment 1 is that as Figure 3 shown, second filling protrusions 31 are arranged at positions corresponding to the gluteal fold on the adhesive surface of the second adhesive component 3. The shapes of the second filling protrusions 31 include hemispherical columnar, semi-elliptical columnar, or triangular columnar with smooth transitions at the corners, and both the diameter and height of the second filling protrusions 31 gradually decrease in the direction away from the endoscope insertion hole 11.

[0083] Furthermore, the materials of the second adhesive component 3 and the second filling protrusions 31 are made of medical polyurethane adhesive and are integrally formed, so that it has good elasticity and deformation ability, can better adapt to the curves of the gluteal folds of different patients, further enhances the sealing effect, and at the same time, also has strong adhesiveness and can be closely adhered to the skin. With such a setting, the patch body 1 can always maintain a stable sealing effect during the colonoscopy examination.

[0084] When the shape of the second filling protrusion 31 is a triangular columnar shape, arc-shaped surfaces are formed by inward depressions on both sides thereof to increase the contact area with the skin and better conform to the curve of the skin.

[0085] The second filling protrusions 31 are mainly arranged at the lower position of the second adhesive component 3 and are collinear with the central axis of the first filling protrusions 21 to make the patch body 1 closely adhered to the skin. In the upper region of the second adhesive component 3 near the waist, since the human body curve changes less, the second filling protrusions 31 can be omitted.
