Description

Technical Field

[0001] The utility model relates to a device for assisting colonic peristalsis through a diameter-limiting band, belonging to the technical field of medical devices. Background Technique

[0002] The colon has the function of continuously absorbing water from the intestinal contents. Therefore, when colonic peristalsis is slow, it causes the symptoms of slow movement of the intestinal contents (the feces to be excreted in the colon are simply referred to as intestinal contents), resulting in the drying of the intestinal contents. The drying of the intestinal contents not only causes abdominal distension, decreased appetite, and dry stools, but also is the main cause of inducing 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 it shows an irregular curved shape. Therefore, there are few devices in the prior art that can assist colonic peristalsis. Currently, the devices used more are mainly of three types: one is the local rotation type; the second is the local vibration type, such as the "bian-stone constipation treatment instrument" with the name CN202021615272X and the "constipation treatment device that can restore intestinal peristalsis through external stimulation" with the name CN2021233631950, etc.; the third is the static pressure type, such as the "anal tube exhaust assistance device" with the name CN2020114458025, etc. The local rotation type has the function of local directional peristalsis, but the acting surface is small and fixed; the local vibration type has an acting surface slightly larger than the rotation type, and its function is to vibrate repeatedly in the covered area and does not have the function of directional peristalsis; the static pressure type can cover most of the colon, but its function is only to apply pressure to the whole colon at the same time, and this type of device does not have the function of directional peristalsis. To sum up, the three types of devices described in the prior art do not have the function of applying a directional peristaltic wave along the colon path, so they cannot meet the real actual needs. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a device for assisting colonic peristalsis through a diameter-limiting band, which is attached to the area on the abdominal surface where the colon of the user is projected in reverse. Through the diameter-limiting band, the cavity diameter of the compressed area of the colon becomes smaller and the internal pressure increases. Under the action of the pressure, the colonic contents are pushed towards the low-pressure area. Because the pressure applied to the colon is a directional conduction wave (the direction of the directional conduction wave is the same as the direction of the colonic peristaltic contraction wave), the colonic contents are continuously moved towards the direction of the pressure wave conduction, so as to play a role in assisting colonic peristalsis, thereby solving the problem of retention of intestinal contents in the background technique.

[0005] The technical solution of the utility model is as follows:

[0006] A device for assisting colonic peristalsis through a diameter-limiting band, comprising a peristaltic band and a power transmission and control unit. The peristaltic band includes a telescopic band, a diameter-limiting band, and an inflatable tube. The telescopic band is elastic. The diameter-limiting band and the telescopic band are of a sleeve structure. The telescopic band is arranged on the inner wall of the diameter-limiting band. The interior of the telescopic band is a closed space and is provided with an inflatable tube. The wall thickness of the telescopic band gradually increases along the length direction. The gas conduit of the power transmission and control unit is connected to the inflatable tube of the telescopic band. Under the control of the power transmission and control unit, by inflating and deflating the telescopic band, a peristaltic pressure wave consistent with the direction of the colonic peristaltic contraction wave is generated. When the telescopic band is inflated, the thinner part of the inner wall of the telescopic band begins to expand. As the inflation pressure gradually increases, the expansion range gradually moves towards the direction of the thicker part of the inner wall, forming a directional peristaltic pressure wave.

[0007] Further, the power transmission and control unit is composed of a gas source supply unit, a solenoid valve group, a control unit, and a gas conduit. The gas source supply unit is connected to the peristaltic band through the solenoid valve group and the gas conduit. The control unit controls the solenoid valve group to achieve inflation and deflation of the peristaltic band, generating a peristaltic pressure wave.

[0008] Further, the gas source supply unit is a well-known and commonly used facility capable of generating and outputting high-pressure gas, such as a gas pump device. The solenoid valve is a well-known and commonly used product. The control unit is composed of electronic devices and a control program (software). During 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 band, and the other end is connected to the solenoid valve group. The function of the gas conduit is power transmission. The functions of the power transmission and control unit are: ① Controlling and driving the peristaltic band to generate a peristaltic pressure wave, ② Controlling the conduction speed of the peristaltic wave, ③ Controlling the pressure value of the peristaltic pressure wave, etc.

[0009] Further, the telescopic band is made of materials with good elasticity such as rubber and latex. The characteristics of the tubular structure of the telescopic band are: the thinner end of the inner wall of the telescopic band as the starting point has the thinnest inner wall. As the length increases, the wall thickness of the inner wall gradually increases. The thicker end of the inner wall of the telescopic band as the ending point has the thickest inner wall.

[0010] Further, the peristaltic band is arranged inside the positioning and fixing band. The positioning and fixing band is fixed firmly at the waist and abdomen.

[0011] Further, the diameter-limiting band is of a tubular structure. Its outer wall is fixed on the positioning and fixing band along the length direction. One side of the diameter-limiting band is pressed by the positioning and fixing band. The directional peristaltic pressure wave formed by inflating the telescopic band mainly acts on the side of the diameter-limiting band attached to the human abdomen.

[0012] Further, the diameter-limiting band is made of materials without elasticity and with a certain strength, such as cloth, etc. The function of the diameter-limiting band is to limit the expansion range of the telescopic band.

[0013] Before using the present utility model, the peristaltic belt needs to be attached to the area on the abdominal surface that is the reverse projection of the user's colon. 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 directed propagation of pressure points, that is, the uninterrupted conduction of pressure from the starting point to the predetermined direction.

[0014] Furthermore, the positioning and fixing belt is made of a material that is not easily deformed. At both ends of the positioning and fixing belt, there are commonly known and commonly used tension adjustment buckles. The tension adjustment buckles at both ends match each other, so that the peristaltic belt can be attached to the human abdomen and the tightness can be adjusted. The positioning and fixing belt has two functions. One is to serve as the fixed base of the peristaltic belt, and the other is to fasten the peristaltic belt to the waist and abdomen.

[0015] The positive effects of the present utility model: It is attached to the area on the abdominal surface that is the reverse projection of the user's colon, making the cavity diameter of the compressed area of the colon smaller and the internal pressure increase. Under the action of the pressure, the contents of the colon are pushed towards the low-pressure area. Due to the pressure conduction of the peristaltic pressure wave, the contents of the colon are continuously moved towards the direction of the wave conduction through the diameter-limiting belt (the direction of the pressure wave conduction is the same as the direction of the colon peristaltic contraction wave). Therefore, it plays a role in assisting colon peristalsis, thus solving the problem of the retention of colon contents in the background. Description of the Drawings

Specific embodiments

[0028] The following further describes the present utility model through embodiments with reference to the accompanying drawings.

[0029] Refer to the attached Figures 1-11 , this embodiment provides a device for assisting colon peristalsis through a diameter-limiting belt, including a peristaltic belt 2 and a power transmission and control unit 3. The peristaltic belt 2 includes a telescopic belt 11, a diameter-limiting belt 12, and an inflatable tube 13. The telescopic belt 11 is elastic. The diameter-limiting belt 12 and the telescopic belt 11 are of a sleeve structure. The telescopic belt 11 is arranged on the inner wall of the diameter-limiting belt 12. The inside of the telescopic belt 11 is a closed space and is provided with an inflatable tube 13. The wall thickness of the telescopic belt 11 gradually increases along the length direction. The gas conduit 9 of the power transmission and control unit 3 is connected to the inflatable tube 13 of the telescopic belt 11. Under the control of the power transmission and control unit 3, a peristaltic pressure wave consistent with the direction of the colon peristaltic contraction wave is generated by inflating and deflating the telescopic belt 11. When the telescopic belt 11 is inflated, the thinner part of the inner wall of the telescopic belt 11 starts to expand. As the inflation pressure gradually increases, the expansion range gradually moves towards the direction of the thicker part of the inner wall, forming a directional peristaltic pressure wave.

[0030] The power transmission and control unit 3 is composed of a gas source supply unit, an electromagnetic valve group, a control unit, and a gas conduit 9. The gas source supply unit is connected to the peristaltic belt 2 through the electromagnetic valve group and the gas conduit 9. The control unit controls the electromagnetic valve group to realize inflation and deflation of the peristaltic belt 2 and generate a peristaltic pressure wave.

[0031] The described gas source supply unit is a well-known and commonly used facility capable of generating and outputting high-pressure gas, such as: air pump devices; the described solenoid valve is a well-known and commonly used product, and the control unit is composed of electronic devices and control programs (software). During use, the control unit controls the gas source supply unit and the solenoid valve group; the gas conduit 9 is a pressure-resistant plastic pipe or rubber pipe, one end of the gas conduit is connected to the peristaltic belt 2, and the other end is connected to the solenoid valve group. The function of the gas conduit is power transmission. The functions of the power transmission and control unit 3 are: ① controlling the driving peristaltic belt 2 to generate peristaltic pressure waves, ② controlling the conduction speed of the peristaltic waves, ③ controlling the pressure value of the peristaltic pressure waves, etc.

[0032] The described telescopic belt 11 is made of materials with good elasticity such as rubber and latex. The tubular structure characteristics of the telescopic belt 11 are: the thinner end 16 of the inner wall of the telescopic belt as the starting point has the thinnest inner wall. As the length increases, the wall thickness of the inner wall gradually thickens. The thicker end 17 of the inner wall of the telescopic belt as the end point has the thickest inner wall.

[0033] The described peristaltic belt 2 is arranged inside the positioning and fixing belt 1; the positioning and fixing belt 1 is firmly fixed at the waist and abdomen position.

[0034] The described diameter-limiting belt 12 is of a tubular 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 is pressed by the positioning and fixing belt 1. The peristaltic pressure wave with directionality formed by the inflation of the telescopic belt 11 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 the predetermined pressure, the thinner part of the inner wall of the telescopic belt 11 begins to expand. During the expansion process, due to the limitation of the limiting belt 12, the expanding radial area of the telescopic belt 11 is always within the constraint range of the limiting belt 12. As the inflation continues, the expansion range of the telescopic belt 11 gradually moves towards the direction of the thicker wall part. Thus, a peristaltic pressure wave with directionality is formed. The deformation and pressure generated by the expansion of the telescopic belt 11 act on the limiting and fixing belt 1 and the abdominal surface. Due to the reverse action of the limiting and fixing belt 1, the radial expansion direction points towards the abdomen, causing the abdominal compression area to collapse inward and show a concave shape. Since the abdominal epithelium and subcutaneous tissue 19 are closely attached to the colon 14, the colon 14 under the concave area is compressed and deformed, resulting in a smaller colon lumen diameter and an increase in internal pressure. The colon contents 15 are squeezed towards the low-pressure area under the action of the pressure. Since the peristaltic pressure wave has directional conductivity, the colon contents are continuously moved in the set direction, thus solving the problem of the retention of colon contents in the background.

[0035] The described diameter-limiting belt 12 is made of materials without elasticity and with 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.

[0036] Before using the present utility model, the peristaltic belt 2 needs to be attached to the abdominal surface area where the colon of the user is projected in reverse. The function of the peristaltic belt 2 is to apply the pressure of the peristaltic pressure wave to the colon through the abdominal subcutaneous tissue. The peristaltic pressure wave refers to the directed propagation of the pressure point, that is, the uninterrupted conduction of the pressure from the starting point to the predetermined direction.

[0037] The positioning and fixing belt 1 is made of a material that is not easily deformed. At both ends of the positioning and fixing belt 1, there are commonly known and commonly used tension adjustment buckles 10. The tension adjustment buckles 10 at both ends match each other, and the peristaltic belt 2 can be attached to the human abdomen and the tightness can be adjusted. The positioning and fixing belt 1 has two functions. One is for the fixed positioning of the peristaltic belt 2, and the other is to fasten the peristaltic belt 2 to the waist and abdomen.
