Abstract
Description
Technical Field
[0001] The utility model relates to a device for assisting colonic peristalsis by inflating and deflating an airbag, 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 will cause 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 dryness of the intestinal contents. The dryness of the intestinal contents will not only cause abdominal distension, loss of appetite and dry stools, but also be 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, as shown in Figure 5 ), there are few devices in the prior art that can assist colonic peristalsis. At present, there are mainly three types of devices used more: 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 by 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 acting surface of the local vibration type is slightly larger than that of the rotation type, and its function is to vibrate repeatedly in the covered area and does not have the function of directional peristalsis; although the static pressure type can cover most of the colon, 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 applying directional peristaltic waves along the colon path. Therefore, it cannot meet the real actual needs. Content of the Utility Model
[0004] The purpose of the utility model is to provide a device for assisting colonic peristalsis by inflating and deflating an airbag, which is attached to the area on the abdominal surface where the colon is projected in reverse of the user. By inflating and deflating the airbag, the lumen 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, playing a role in assisting colonic peristalsis, thereby solving the problem of retention of colonic contents in the background technique.
[0005] The technical solution of the utility model is:
[0006] A device for assisting colonic peristalsis by inflating and deflating an airbag, comprising a peristaltic belt and a power transmission and control unit. The peristaltic belt is formed by arranging a plurality of airbags and fixing them on the inner side of a positioning and fixing belt. The shape formed by arranging the plurality of airbags is consistent with the shape of the human colon. The peristaltic belt is attached to the human abdomen through the positioning and fixing belt, and the power transmission and control unit is respectively connected to the airbags on the peristaltic belt. The plurality of airbags generate peristaltic pressure waves by inflating and deflating, and generate peristaltic pressure waves in the same direction as the colonic peristaltic contraction waves through inflating and deflating.
[0007] Further, the power transmission and control unit is composed of an air source supply unit, a solenoid valve group, a control unit, and a gas conduit. The air source supply unit is respectively connected to the peristaltic belt through a multi-way solenoid valve group and a plurality of gas conduits. The control unit controls the solenoid valve group to sequentially inflate and deflate the peristaltic belt to generate peristaltic pressure waves.
[0008] The air 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 solenoid valves are well-known and commonly used products, and the control unit is composed of electronic devices and control programs (software). During use, the control unit controls the air source supply unit and the solenoid valve group; the gas conduit is a pressure-resistant plastic pipe or rubber pipe. 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. The functions of the power transmission and control unit are: ① Controlling and driving the peristaltic belt 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.
[0009] The airbag is provided with a gas charging and discharging interface, and the gas conduit of the power transmission and control unit is connected to the gas charging and discharging interface; the airbag expands after inflation and returns to its state before inflation after releasing the gas. By controlling the power transmission and control unit to sequentially inflate, stop inflating to maintain pressure, and deflate the airbag, a round of pressure point conduction process of the peristaltic pressure wave is completed. The pressure of the peristaltic pressure wave acts between the positioning and fixing belt and the abdominal epithelium. Due to the non-stretchability 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 to show a concave shape. Since the abdominal subcutaneous tissue is closely attached to the colon, the colon under the concave area is compressed and deformed, resulting in a smaller colon lumen diameter and an increase in internal pressure. The intestinal contents are squeezed towards the low-pressure area under the action of the pressure. Due to the directional conductivity of the peristaltic pressure wave, the colonic contents are continuously moved in the set direction, thus solving the problem of colonic content retention in the background.
[0010] Further, the airbag is made of airtight materials, such as: rubber, plastic and other materials.
[0011] Further, the peristaltic belt is arranged inside the positioning and fixing belt, and a plurality of air bags are embedded in the positioning and fixing belt; the positioning and fixing belt is firmly fixed at the waist and abdomen position.
[0012] Further, 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 used tightening adjustment buckles. The tightening adjustment buckles at both ends match each other, attaching the peristaltic belt to the human abdomen and allowing the tightness to be adjusted. The positioning and fixing belt has two functions. One is to fix and position the peristaltic belt, and the other is to fasten the peristaltic belt to the waist and abdomen.
[0013] Before using the present utility model, the peristaltic belt needs to be attached to the area on the abdominal surface where the colon of the user is projected in reverse. 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 continuous conduction of the pressure from the starting point to the predetermined direction.
[0014] The positive effects of the present utility model: It is attached to the area on the abdominal surface where the colon of the user is projected in reverse. By inflating and deflating the air bag, the cavity diameter of the compressed area of the colon becomes smaller and the internal pressure increases. Under the action of the pressure, the colon contents are pushed towards the low-pressure area. Due to the pressure conduction of the peristaltic pressure wave, the colon contents continuously move in the direction of the wave conduction (the direction of the 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 implementation mode
[0024] The following further describes the present utility model through embodiments in conjunction with the attached drawings.
[0025] Refer to the attached Figure 1-8 , this embodiment provides a device for assisting colon peristalsis by inflating and deflating an airbag, which includes a peristaltic belt 2 and a power transmission and control unit 3. The peristaltic belt 2 is formed by arranging a plurality of airbags 4 and fixing them inside the positioning and fixing belt 1. The shape formed by arranging the plurality of airbags 4 is consistent with the shape of the human colon; the positioning and fixing belt 1 is attached to the human abdomen, and the power transmission and control unit 3 is respectively connected to the airbags on the peristaltic belt 2; the plurality of airbags generate peristaltic pressure waves by inflating and deflating to generate peristaltic pressure waves in the same direction as the colon peristaltic contraction waves.
[0026] The power transmission and control unit 3 is composed of a gas source supply unit, a solenoid valve group, a control unit, and a gas conduit 9. The gas source supply unit is respectively connected to the peristaltic belt 2 through a multi-way solenoid valve group and a plurality of gas conduits 9. The control unit controls the solenoid valve group to sequentially inflate and deflate the peristaltic belt 2 to generate peristaltic pressure waves.
[0027] The 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 solenoid valves are well-known and commonly used products, 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 9 is communicated with the peristaltic belt 2, and the other end is communicated with the solenoid valve group. The function of the gas conduit 9 is power transmission. The functions of the power transmission and control unit 3 are: ① controlling and driving the 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.
[0028] The airbag 4 is provided with a gas charging and discharging interface 5, and the gas conduit 9 of the power transmission and control unit 3 is connected to the gas charging and discharging interface 5; the airbag 4 expands after inflation and returns to the state before inflation after releasing the gas. By controlling the power transmission and control unit 3 to sequentially inflate, stop inflating to maintain pressure, and deflate the airbag, a pressure point conduction process of a peristaltic pressure wave is completed. The pressure of the peristaltic pressure wave acts between the positioning and fixing belt 1 and the abdominal epithelium. Due to the non-stretchability 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 to show a concave shape. Since the abdominal subcutaneous tissue is closely attached to the colon, the colon under the concave area is compressed and deformed, resulting in a smaller colon lumen diameter and an increase in internal pressure. The intestinal contents are squeezed towards the low-pressure area under the action of the pressure. Due to the directional conductivity of the peristaltic pressure wave, the colon contents are continuously moved in the set direction, thus solving the problem of colon content retention in the background.
[0029] The described airbag 4 is made of airtight materials, such as: rubber, plastic and other materials.
[0030] The peristaltic belt 2 is arranged on the inner side of the positioning and fixing belt 1, and a plurality of airbags are embedded in the positioning and fixing belt 1; the positioning and fixing belt 1 is firmly fixed at the waist and abdomen.
[0031] The positioning and fixing belt 1 is made of materials that are not easily deformed. At both ends of the positioning and fixing belt 1, there are publicly known and commonly used tension adjustment buckles 10. The tension adjustment buckles 10 at both ends match each other, attaching the peristaltic belt 2 to the human abdomen and allowing the tightness to 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.
[0032] In the embodiment, the peristaltic belt 2 is composed of 18 airbags arranged in 4 rows and inlaid on the inner side of the positioning and fixing belt 1, and its shape is consistent with the shape of the human colon; the 18 airbags are numbered 1-18 from head to tail. The airbags 1-5 match the ascending colon position, the airbags 5-12 match the transverse colon of the human body, the airbags 12-16 match the descending colon of the human body, and the airbags 16-18 match the sigmoid colon of the human body.
[0033] The peristaltic belt 2 matches the position of the colon of the user, and the peristaltic belt 2 is attached to the area on the abdominal surface that is the reverse projection of the colon (see Figure 5 、 Figure 7 shown), adjust the tightness of the positioning and fixing belt 1 to be closely attached to the waist and abdomen, and fasten the tension adjustment buckle 10 (see Figure 8As shown, confirm that all gas conduits 9 are connected to the relevant airbags 4. Start the power transmission and control unit 3. Under the control and drive of the power transmission and control unit 3, the following actions are achieved: ① Generate a peristaltic pressure wave: Inflate the airbag 4 at the set starting point → When the inflation pressure reaches the predetermined value → Stop inflation and maintain the pressure → Inflate the next adjacent airbag 4 → When the inflation pressure reaches the predetermined value → Stop inflation and maintain the pressure → Release the gas of the previous airbag 4 that maintained the pressure → Inflate the next adjacent airbag 4. Repeat the above processes of inflation, stopping inflation and maintaining the pressure, and deflation until the last set airbag 4 performs deflation, completing the pressure point conduction process of one round of peristaltic pressure wave. The generated peristaltic pressure wave is as Figure 6 shown. ② The colonic contents are directionally moved: 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 non-stretchability 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 to show a concave shape. Since the abdominal subcutaneous tissue is closely attached to the colon, the colon under the concave area is compressed and deformed, resulting in a smaller colon lumen diameter and an increase in internal pressure. The intestinal contents are squeezed towards the low-pressure area under the action of the pressure. Due to the directional conductivity of the peristaltic pressure wave, the colonic contents are continuously moved in the set direction. The process is shown in Figure 6 shown, thus solving the problem of colonic content retention in the background.
