Description

Technical Field

[0001] The invention relates to a belt-shaped auxiliary colon peristalsis device, belonging to the technical field of medical equipment. Background Art

[0002] The colon has the function of continuously absorbing water from intestinal contents. Therefore, when the peristalsis of the colon is slow, it causes the symptom of slow movement of the intestinal contents (the feces to be excreted in the colon are referred to as intestinal contents), thereby causing the intestinal contents to dry up. Dry intestinal contents will not only cause abdominal distension, loss of appetite and dry stools, but are also the main cause of colitis, colon cancer, defecation-type cerebral hemorrhage and hemorrhoids.

[0003] Due to the particularity of the shape and location of the colon (the average length of the colon is 1.5 meters and its irregular curvature, Figure 5 As shown), therefore, there are few devices in the prior art that can assist colon peristalsis. At present, there are three main types of devices that are used more frequently: one is the local rotation type; the second is the local vibration type, such as CN202021615272X, named "Bianshi constipation treatment instrument" and CN2021233631950, named "a device for treating constipation that can restore intestinal peristalsis through in vitro stimulation", etc.; the third is the static pressure type, such as CN2020114458025, named "anal canal exhaust assist device", etc. The local rotation type has the function of local directional peristalsis, but the action surface is small and fixed; the action surface of the local vibration type is slightly larger than that of the rotation type, and its function is to vibrate repeatedly in the coverage area, and it does not have the directional peristalsis function; although the static pressure type can cover most of the colon, its function is only to apply pressure to the entire colon at the same time, and this type of device does not have the directional peristalsis function. In summary, the three types of devices described in the prior art do not have the function of applying directional peristaltic waves along the colon path, and therefore cannot meet the real practical needs. Summary of the invention

[0004] The purpose of the present invention is to provide a belt-shaped assisted colon peristalsis device, which is attached to the user's colon and projected backward on the abdominal surface area, so that the cavity diameter of the colon pressure area becomes smaller and the internal pressure increases. Under the action of pressure, the colon contents are pushed to the low-pressure area. Because the pressure applied to the colon is a directional conduction wave (the direction of the directional conduction wave is consistent with the direction of the colon peristaltic contraction wave), the colon contents are continuously moved in the direction of the pressure wave conduction, thereby playing a role in assisting colon peristalsis, thereby solving the problem of intestinal content retention in the background technology.

[0005] The technical solution of the present invention is: A belt-shaped assisted colon peristalsis device comprises a positioning and fixing belt, a peristaltic belt and a power transmission and control unit, wherein the peristaltic belt is arranged on the inner side of the positioning and fixing belt; the positioning and fixing belt is firmly fixed at the waist and abdomen, and under the control of the power transmission and control unit, the peristaltic belt generates a peristaltic pressure wave in the same direction as the colon peristaltic contraction wave, and the peristaltic pressure wave applies pressure to the colon through the abdominal epithelium and subcutaneous tissue, so that the cavity diameter of the compressed area of ​​the colon becomes smaller and the internal pressure increases, and under the action of pressure, the colon contents in the compressed section are pushed to the low-pressure area, and due to the conduction effect of the peristaltic pressure wave, the colon contents continuously move in the conduction direction of the wave, thereby assisting colon peristalsis and solving the problem of colon content retention.

[0006] Furthermore, the power transmission control unit is composed of an air supply unit, an electromagnetic valve group, a control unit and a gas duct. The air supply unit is connected to the peristaltic belt through a multi-way electromagnetic valve group and multiple gas ducts respectively. The control unit controls the electromagnetic valve group to realize sequential inflation and deflation of the peristaltic belt to generate peristaltic pressure waves.

[0007] Furthermore, the gas source supply unit is a known public facility capable of generating and outputting high-pressure gas, such as an air pump device; the solenoid valve is a known public product, and the control unit is composed of electronic devices and a control program (software). In use, the control unit controls the gas source supply unit and the solenoid valve group; the gas conduit is a pressure-resistant plastic tube or rubber tube, one end of the gas conduit is connected to the peristaltic belt, and the other end is connected to the solenoid valve group. The function of the gas conduit is power transmission, and the functions of the power transmission control unit are: ① control the drive peristaltic belt to generate peristaltic pressure waves, ② control the conduction speed of the peristaltic wave, ③ control the pressure value of the peristaltic pressure wave, etc.

[0008] Before using the present invention, the peristaltic belt needs to be attached to the user's colon and projected backwards onto the abdominal surface area. The function of the peristaltic belt is to apply the pressure of the peristaltic pressure wave to the colon through the subcutaneous tissue of the abdomen. The peristaltic pressure wave refers to the directional propagation of the pressure point, that is, the uninterrupted conduction of pressure from the starting point to the predetermined direction.

[0009] The peristaltic belt may generate peristaltic pressure waves in the same direction as the peristaltic contraction waves of the colon in any manner, in particular, by means of inflation and deflation to generate peristaltic pressure waves in the same direction as the peristaltic contraction waves of the colon.

[0010] The peristaltic belt of the present invention, which generates a peristaltic pressure wave in the same direction as the peristaltic contraction wave of the colon by means of inflation and deflation, includes at least the following two types: 1. The peristaltic belt is formed by arranging a plurality of air bags and fixing them on the inner side of a positioning and fixing belt. The shape formed by arranging the air bags is consistent with the shape of the human colon. The positioning and fixing belt is attached to the abdomen of the human body, and the power transmission and control unit is connected to the air bags on the peristaltic belt respectively. The air bags generate peristaltic pressure waves in the same direction as the peristaltic contraction waves of the colon by inflation and deflation.

[0011] The airbag is provided with a gas charging and discharging interface, and the gas conduit of the power transmission control unit is connected to the gas charging and discharging interface; the airbag expands after being inflated, and returns to the state before inflation after releasing the gas. The power transmission control unit controls the airbag to be inflated, stopped to maintain pressure and deflated in sequence, completing a round of pressure point conduction process of peristaltic pressure wave. The pressure of the peristaltic pressure wave acts between the positioning and fixing belt and the abdominal epithelium. Due to the inextensibility of the positioning and fixing belt, the expansion direction and pressure of each airbag act on the abdominal surface. Under the action of the expansion force of the airbag, the compressed area of ​​the abdomen collapses inward and becomes concave. Since the subcutaneous tissue of the abdomen is closely attached to the colon, the colon under the concave area is compressed and deformed, resulting in a smaller colon cavity diameter and an increase in internal pressure. The intestinal contents are squeezed to the low-pressure area under the action of pressure. Since the peristaltic pressure wave has directional conductivity, the colon contents are continuously moved in the set direction, thereby solving the problem of colon contents being retained in the background.

[0012] The multiple air bags are embedded in the positioning and fixing belt, and the air bags are made of airtight materials, such as rubber, plastic and other materials.

[0013] 2. The peristaltic belt includes a telescopic belt, a diameter limiting belt and an inflation tube. The telescopic belt is elastic. The diameter limiting belt and the telescopic belt are sleeve structures. The telescopic belt is arranged on the inner wall of the diameter limiting belt. The interior of the telescopic belt is a closed space and is provided with an inflation tube. The wall thickness of the telescopic belt gradually increases along the length direction. The gas duct of the power transmission and control unit is connected to the inflation tube of the telescopic belt. Under the control of the power transmission and control unit, a peristaltic pressure wave consistent with the direction of the colon peristaltic contraction wave is generated by inflating and deflating the telescopic belt.

[0014] When the expansion band is inflated, the thinner part of the inner wall of the expansion band begins to expand. As the inflation pressure gradually increases, the expansion range gradually moves toward the thicker part of the inner wall, forming a directional peristaltic pressure wave.

[0015] Furthermore, the diameter limiting belt is a cylindrical structure, and its outer wall is fixed on the positioning and fixing belt along the length direction. One side of the diameter limiting belt is compressed by the positioning and fixing belt. The expansion belt is inflated to form a directional peristaltic pressure wave, which mainly acts on the side of the diameter limiting belt attached to the human abdomen. When the peristaltic belt is inflated through the inflation tube and reaches a predetermined pressure, the thinner part of the inner wall of the expansion belt begins to expand. During the expansion process, due to the limitation of the positioning and fixing belt, the expansion radial area of ​​the expansion belt is always within the constraint range of the positioning and fixing belt. As the inflation continues, the expansion range of the expansion belt gradually moves toward the direction of the thicker wall part, thereby forming a directional peristaltic pressure wave. The deformation and pressure generated by the expansion of the telescopic belt act on the limiting fixing belt and the abdominal surface. Due to the reverse action of the limiting fixing belt, the radial expansion direction is directed to the abdomen, causing the compressed area of ​​the abdomen to collapse inward and become concave. Since the abdominal epithelium and subcutaneous tissue are tightly attached to the colon, the colon under the concave area is compressed and deformed, resulting in a smaller colon cavity diameter and increased internal pressure. The colon contents are squeezed to the low-pressure area under the action of pressure. Since the peristaltic pressure wave has directional conductivity, the colon contents are continuously moved in the set direction, thereby solving the problem of colon contents retention in the background.

[0016] Furthermore, the telescopic belt is made of a material with good elasticity such as rubber or latex. The cylindrical structure of the telescopic belt is characterized in that the inner wall at the starting point is thinner, and as the length increases, the thickness of the inner wall gradually increases.

[0017] Furthermore, the diameter limiting belt is made of a material that is inelastic but has a certain strength, such as cloth, etc. The function of the diameter limiting belt is to limit the expansion range of the telescopic belt.

[0018] Furthermore, the positioning and fixing belt is made of a material that is not easily deformed, and well-known and commonly used elastic adjustment buckles are provided at both ends of the positioning and fixing belt, and the elastic adjustment buckles at both ends match each other, so that the peristaltic belt is attached to the abdomen of the human body and the elasticity can be adjusted. The positioning and fixing belt has two functions: one is to fix the peristaltic belt, and the other is to fasten the peristaltic belt to the waist and abdomen.

[0019] The positive effects of the present invention are as follows: the colon attached to the user is reversely projected onto the abdominal surface area, which reduces the diameter of the colon pressure area and increases the internal pressure. Under the action of pressure, the colon contents are pushed to the low-pressure area. Due to the pressure conduction effect of the peristaltic pressure wave, the colon contents continuously move in the conduction direction of the wave (the conduction direction of the pressure wave is consistent with the direction of the colon peristaltic contraction wave). Therefore, it plays a role in assisting colon peristalsis, thereby solving the problem of colon content retention in the background. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The present invention will be further described below through embodiments in conjunction with the accompanying drawings.

[0022] A belt-shaped assisted colon peristalsis device comprises a positioning and fixing belt 1, a peristaltic belt 2 and a power transmission and control unit 3, wherein the peristaltic belt 2 is arranged on the inner side of the positioning and fixing belt 1; the positioning and fixing belt 1 is firmly fixed at the waist and abdomen, and the peristaltic belt 2, under the control of the power transmission and control unit 3, generates a peristaltic pressure wave in the same direction as the colon peristaltic contraction wave, and the peristaltic pressure wave applies pressure to the colon through the abdominal epithelium and subcutaneous tissue, so that the cavity diameter of the compressed area of ​​the colon becomes smaller and the internal pressure increases. Under the action of pressure, the colon contents in the compressed section are pushed to the low-pressure area, and due to the conduction effect of the peristaltic pressure wave, the colon contents continuously move in the conduction direction of the wave, thereby assisting colon peristalsis and solving the problem of colon content retention.

[0023] Preferably, the positioning and fixing belt 1 is made of a material that is not easily deformed, and well-known and commonly used elastic adjustment buckles 10 are provided at both ends of the positioning and fixing belt 1. The elastic adjustment buckles 10 at both ends match each other, and the peristaltic belt 2 is attached to the abdomen of the human body and the elasticity can be adjusted. The positioning and fixing belt 1 has two functions: one is to fix the peristaltic belt 2, and the other is to fasten the peristaltic belt 2 to the waist and abdomen.

[0024] The power transmission control unit 3 is composed of an air supply unit, an electromagnetic valve group, a control unit and a gas conduit 9. The air supply unit is connected to the peristaltic belt 2 through a multi-way electromagnetic valve group and multiple gas conduits 9 respectively. The control unit controls the electromagnetic valve group to realize the sequential inflation and deflation of the peristaltic belt 2 to generate peristaltic pressure waves.

[0025] The gas source supply unit is a known public facility capable of generating and outputting high-pressure gas, such as an air pump device; the solenoid valve is a known public product, and the control unit is composed of electronic devices and a control program (software). In use, the control unit controls the gas source supply unit and the solenoid valve group; the gas conduit 9 is a pressure-resistant plastic tube or rubber tube, one end of the gas conduit 9 is connected to the peristaltic belt 2, and the other end is connected to the solenoid valve group. The function of the gas conduit 9 is power transmission, and the functions of the power transmission control unit 3 are: ① control the peristaltic belt 2 to generate a peristaltic pressure wave, ② control the conduction speed of the peristaltic wave, ③ control the pressure value of the peristaltic pressure wave, etc.

[0026] Before using the present invention, the peristaltic belt 2 needs to be attached to the user's colon and projected backwards onto the abdominal surface area. The function of the peristaltic belt 2 is to apply the pressure of the peristaltic pressure wave to the colon through the subcutaneous tissue of the abdomen. The peristaltic pressure wave refers to the directional propagation of the pressure point, that is, the uninterrupted conduction of pressure from the starting point to the predetermined direction.

[0027] The peristaltic belt 2 can generate peristaltic pressure waves in the same direction as the peristaltic contraction wave of the colon in any manner, in particular, by inflating and deflating to generate peristaltic pressure waves in the same direction as the peristaltic contraction wave of the colon.

[0028] Embodiment 1, refer to the attached Figure 2-8 : The peristaltic belt 2 is formed by arranging a plurality of air bags 4 and fixing them on the inner side of the positioning and fixing belt 1. The shape formed by arranging the plurality of air bags 4 is consistent with the shape of the human colon. The positioning and fixing belt 1 is attached to the abdomen of the human body, and the power transmission and control unit 3 is respectively connected to the air bags on the peristaltic belt 2. The plurality of air bags generate peristaltic pressure waves consistent with the direction of the peristaltic contraction waves of the colon by inflation and deflation.

[0029] The airbag 4 is provided with a gas charging and discharging interface 5, and the gas conduit 9 of the power transmission control unit 3 is connected to the gas charging and discharging interface 5; the airbag 4 expands after being inflated, and returns to the state before being inflated after the gas is released. The power transmission control unit 3 controls the airbag to be inflated, stopped to maintain pressure, and deflated in sequence, completing a round of pressure point conduction process of peristaltic pressure waves.

[0030] The multiple airbags are embedded in the positioning and fixing belt 1, and the airbags 4 are made of airtight materials, such as rubber, plastic and the like.

[0031] In embodiment 1, the peristaltic belt 2 is composed of 18 air bags arranged in 4 rows and embedded on the inner side of the positioning and fixing belt 1, and the shape is consistent with the shape of the human colon; the 18 air bags are air bags No. 1-18 from the beginning to the end, air bags No. 1-5 match the position of the ascending colon, air bags No. 5-12 match the transverse colon of the human body, air bags No. 12-16 match the descending colon of the human body, and air bags No. 16-18 match the sigmoid colon of the human body.

[0032] The peristaltic belt 2 matches the position of the user's colon and is attached to the area where the colon is projected backward on the abdominal surface (see Figure 5 , Figure 7 As shown in the figure), adjust the tightness of the positioning and fixing belt 1 to fit tightly against the waist and abdomen, and fasten the tightness adjustment buckle 10 (see Figure 8 As shown), confirm that all gas conduits 9 are connected to the relevant airbags 4, start the power transmission control unit 3, and under the control and drive of the power transmission control unit 3, implement the following actions: ① Generate peristaltic pressure waves: inflate the airbag 4 at the set starting point → when the inflation pressure reaches the preset pressure value → stop inflating and maintain pressure → inflate the next adjacent airbag 4 → when the inflation pressure reaches the preset pressure value → stop inflating and maintain pressure → release the gas of the previous airbag 4 that maintains pressure → inflate the next adjacent airbag 4, repeat the above-mentioned process of inflation, stopping inflation and maintaining pressure, and deflation until the last set airbag 4 is deflated, completing a round of pressure point conduction process of peristaltic pressure waves, and the generated peristaltic pressure waves are as shown in FIG. Figure 6As shown. ② The colon contents are directed to move: The pressure of the peristaltic pressure wave generated in action ① acts between the positioning and fixing belt 1 and the abdominal epithelium. Due to the inextensibility of the positioning and fixing belt 1, the expansion direction and pressure of each airbag 4 act on the abdominal surface. Under the action of the expansion force of the airbag 4, the compressed area of ​​the abdomen collapses inward and becomes concave. Since the subcutaneous tissue of the abdomen is in close contact with the colon, the colon under the concave area is compressed and deformed, resulting in a smaller colon cavity diameter and increased internal pressure. Under the action of pressure, the intestinal contents are squeezed to the low-pressure area. Since the peristaltic pressure wave has directional conductivity, the colon contents are continuously moved in the set direction. The process is shown in Figure 6 As shown, the problem of retention of colonic contents in the background is resolved.

[0033] Embodiment 2, refer to the attached Figure 9-16 .

[0034] The peristaltic belt 2 includes a telescopic belt 11, a diameter limiting belt 12 and an inflation tube 13. The telescopic belt 11 is elastic. The diameter limiting belt 12 and the telescopic belt 11 are sleeve structures. The telescopic belt 11 is arranged on the inner wall of the diameter limiting belt 12. The interior of the telescopic belt 11 is a closed space and is provided with an inflation tube 13. The wall thickness of the telescopic belt 11 gradually increases along the length direction. The gas duct 9 of the power transmission and control unit 3 is connected to the inflation tube 13 of the telescopic belt 11. Under the control of the power transmission and control unit 3, the telescopic belt 11 is inflated and deflated to generate a peristaltic pressure wave consistent with the direction of the colon peristaltic contraction wave.

[0035] When the stretch band 11 is inflated, the thinner portion of the inner wall of the stretch band 11 begins to expand. As the inflation pressure gradually increases, the expansion range gradually moves toward the thicker portion of the inner wall, forming a directional peristaltic pressure wave.

[0036] The diameter limiting belt 12 is a cylindrical structure, and its outer wall is fixed on the positioning and fixing belt 1 along the length direction. One side of the diameter limiting belt 12 is compressed by the positioning and fixing belt 1. The expansion belt 11 is inflated to form a directional peristaltic pressure wave, which mainly acts on the side of the diameter limiting belt attached to the human abdomen. When the peristaltic belt is inflated through the inflation tube 13 and reaches a predetermined pressure, the thinner part of the inner wall of the expansion belt 11 begins to expand. During the expansion process, due to the limitation of the positioning and fixing belt 12, the expansion radial area of ​​the expansion belt 11 is always within the constraint range of the positioning and fixing belt 12. As the inflation continues, the expansion range of the expansion belt 11 gradually moves toward the direction of the thicker wall part, thereby forming a directional peristaltic pressure wave. The deformation and pressure generated by the expansion of the telescopic belt 11 act on the limiting fixing belt 1 and the abdominal surface. Due to the reverse action of the limiting fixing belt 1, the radial expansion direction is directed to the abdomen, causing the compressed area of ​​the abdomen to collapse inward and become concave. Since the abdominal epithelium and subcutaneous tissue 19 are tightly attached to the colon 14, the colon 14 under the recessed area is compressed and deformed, resulting in a smaller colon cavity diameter and increased internal pressure. The colon contents 15 are squeezed to the low-pressure area under the action of pressure. Since the peristaltic pressure wave has directional conductivity, the colon contents 15 are continuously moved in the set direction, thereby solving the problem of colon content retention in the background.

[0037] The stretch band 11 is made of a material with good elasticity such as rubber and latex. The tubular structure of the stretch band 11 has the following characteristics: the inner wall of the thinner end 16 of the stretch band as the starting point is the thinnest, and as the length increases, the inner wall thickness gradually increases, and the inner wall of the thicker end 17 of the stretch band as the end point is the thickest.

[0038] The diameter limiting belt 12 is made of a material that is inelastic but has a certain strength, such as cloth, etc. The function of the diameter limiting belt 12 is to limit the expansion range of the telescopic belt 11.
