Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an intestinal implantable intestinal peristalsis regulating device. Background Art

[0002] The human intestine is an important digestive organ of the human body. The intestine is the digestive tract from the pylorus of the stomach to the anus. It is the longest section of the digestive tract and also the most important section in terms of function. Intestinal peristalsis refers to worm-like movements, especially the wave-like contractions of the intestine. Reduced and slowed intestinal peristalsis can easily lead to intestinal motility disorders, which is the main cause and pathophysiological basis of functional bowel diseases. It can cause functional dyspepsia and irritable bowel syndrome, etc. Clinical manifestations include abdominal pain, diarrhea, constipation, abdominal distension, incomplete defecation, and urgency to defecate. Many patients also suffer from insomnia, anxiety, depression, headache, and inattention, which seriously affect their quality of life. Currently, ways to promote intestinal peristalsis include eating fiber foods and taking pro-intestinal peristalsis drugs and pro-intestinal peristalsis bacteria, but the former only has preventive and relieving effects, while the efficacy of taking drugs is uncertain, the control effect is poor, and it is easy to relapse.

[0003] The Chinese invention patent with the authorization announcement number CN115463017A discloses a gastrointestinal peristalsis-promoting device, which uses an air bag to inflate a rubber ball, and the expanded rubber ball is attached to the inner wall of the intestine for massage. However, the defect is that the device needs to be manually pulled or pushed to make the rubber ball perform local and all-round massage in the intestine, which is quite different from the movement form of intestinal peristalsis itself, and the effect of promoting intestinal peristalsis is poor, which is easy to cause discomfort. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the existing gastrointestinal peristalsis-promoting device needs to be manually pulled or pushed to make the rubber ball perform local and all-round massage in the intestine, which is quite different from the movement form of intestinal peristalsis itself, has a poor effect in promoting intestinal peristalsis, and is prone to cause discomfort.

[0005] In order to solve the above problems, the utility model provides an intestinal implantable intestinal peristalsis regulating device, including a plurality of annular air bags arranged in sequence and sleeved inside the intestine, the inner sides of the annular air bags are sealed and fixed to a support tube; it also includes an air source, which can inflate the plurality of annular air bags in sequence, after inflation, the outer sides of the annular air bags contact and squeeze the inner wall of the intestine, and are squeezed in the direction of the intestine by adjacent annular air bags.

[0006] The intestinal implantable intestinal peristalsis regulating device provided by the utility model also has the following technical features:

[0007] The cross section of the annular airbag is C-shaped.

[0008] An intermediate airbag is arranged between two adjacent annular airbags. The intermediate airbag is supplied with air by an air source. The inner side of the intermediate airbag is sealed and fixed to the support tube, and the outer side of the intermediate airbag is sealed and fixed to the adjacent annular airbags.

[0009] The diameter and volume of the intermediate airbag are smaller than the diameter and volume of the annular airbag.

[0010] The annular airbag is connected with an air inlet pipe and an air outlet pipe, and one-way valves are provided on the air inlet pipe and the air outlet pipe respectively. A pressure gauge is provided on the air inlet pipe and is connected with the output end of the air source. The air source and the one-way valve are both controlled by a control module.

[0011] The diameter of the support tube is 1 / 2 to 2 / 3 of the diameter of the intestine.

[0012] The utility model has the following beneficial effects: firstly, the first annular airbag is inflated, and the outer side of the first annular airbag contacts and squeezes the inner wall of the intestine, and then the adjacent second annular airbag is inflated. Since the inner side of the annular airbag is fixed on the supporting tube, the first annular airbag is squeezed in the direction of the intestine by the adjacent second annular airbag, so that the first annular airbag further squeezes and pushes the inner wall of the intestine, and then the first annular airbag is deflated and the third annular airbag adjacent to the second annular airbag is inflated, and this cycle is repeated. While massaging the intestine, automatic pushing-type auxiliary peristalsis of the intestine is achieved, which is similar to the movement form of intestinal peristalsis itself, has a good effect in promoting intestinal peristalsis, and is not easy to cause discomfort.

[0017] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0018] like Figures 1 to 4As shown, the intestinal implantable intestinal peristalsis regulating device of the utility model includes a plurality of annular air bags 11 which are sequentially arranged and sleeved inside the intestine 10, and is characterized in that the inner side of the annular air bags 11 is sealed and fixed to the support tube 21; it also includes an air source, which can inflate the plurality of annular air bags 11 in sequence. After inflation, the outer side of the annular air bags 11 contacts and squeezes the inner wall of the intestine 10, and is squeezed in the direction of the intestine 10 by the adjacent annular air bags 11.

[0019] The utility model first inflates the first annular airbag 11, and the outer side of the first annular airbag 11 contacts and squeezes the inner wall of the intestine 10, and then inflates the adjacent second annular airbag 11. Since the inner side of the annular airbag 11 is fixed on the support tube 21, the first annular airbag 11 is squeezed in the direction of the intestine 10 by the adjacent second annular airbag 11, so that the first annular airbag 11 further squeezes and pushes the inner wall of the intestine 10, and then the first annular airbag 11 is deflated and the third annular airbag 11 adjacent to the second annular airbag 11 is inflated. According to this cycle, while massaging the intestine 10, automatic pushing-type auxiliary peristalsis of the intestine 10 is achieved, which is similar to the movement form of intestinal peristalsis itself, has a good effect of promoting intestinal peristalsis, and is not easy to cause discomfort.

[0020] Among them, the annular airbag 11 adopts elastic medical materials, such as medical PE plastic, medical silicone, and medical rubber; in addition, the elasticity of the support tube 21 is smaller than the elasticity of the annular airbag 11, so as to achieve support for the inner side of the annular airbag 11 to avoid expansion of the inner side of the annular airbag 11 after inflation, thereby avoiding affecting the physiological work inside the intestine 10.

[0021] The air source may be an air storage bag, an air pump or other device capable of supplying air to the annular air bag 11 .

[0022] Preferably, the cross section of the annular airbag 11 is C-shaped.

[0023] The utility model can realize the pushing-type auxiliary peristalsis of the intestine 10 by sequentially inflating and deflating the annular airbag 11 .

[0024] The cross section of the annular airbag 11 is a C-shape with a small top and a large bottom or a C-shape with a large top and a small bottom, so as to achieve a push-type auxiliary peristalsis of the intestine 10 from top to bottom or from bottom to top.

The inner side of the intermediate airbag 22 is sealed and fixed to the support tube 21 , and the outer side of the intermediate airbag 22 is sealed and fixed to the adjacent annular airbags 11 .

[0026] The utility model sets an intermediate airbag 22 between two adjacent annular airbags 11. After the first annular airbag 11 is inflated, the intermediate airbag 22 is inflated first, and then the second annular airbag 11 is inflated, so that the intermediate airbag 22 can fill the gap between the first annular airbag 11 and the second annular airbag 11, so that after the second annular airbag 11 is inflated, the first annular airbag 11 can be better squeezed by the intermediate airbag 22, so that the first annular airbag 11 can further squeeze and push the inner wall of the intestine 10, thereby enhancing the pushing-type auxiliary peristalsis effect on the intestine 10.

[0027] The cross section of the intermediate airbag 22 is C-shaped.

[0028] Preferably, the diameter and volume of the intermediate airbag 22 are smaller than the diameter and volume of the annular airbag 11 .

[0029] Preferably, see Figure 3 , 4 The annular airbag 11 and the intermediate airbag 22 are connected to an air inlet pipe 31 and an air outlet pipe 32. The air inlet pipe 31 and the air outlet pipe 32 are respectively provided with a one-way valve 33. The air inlet pipe 31 is provided with a pressure gauge 34, which is connected to the output end of the air source. The air source and the one-way valve 33 are both controlled by a control module.

[0033] Specifically, see Figure 3 , 4 The extended air inlet pipe 31 and the air outlet pipe 32 can be buried in the support barrel 21 in the following manner:

[0034] A main air intake hole 41 and a branch air intake hole 42 are provided on one side of the support barrel 21 and along the length thereof. A plurality of air intake pipes 31 are buried in the main air intake hole 41 and are connected to the corresponding annular airbags 11 or intermediate airbags 22 in sequence through the branch air intake holes 42.

[0035] Correspondingly, a main air outlet hole 43 and a branch air outlet hole 44 are opened on the other side of the support barrel 21 and along its length direction. The main air outlet hole 43 is used to bury multiple air outlet pipes 32, and is connected to the corresponding annular airbag 11 or intermediate airbag 22 through the branch air outlet holes 44 in turn.

[0039] See also Figure 3 , from top to bottom, they are the first to third annular airbags 11, and the first and second intermediate airbags 22 between adjacent annular airbags 11; the control module controls the air source to open and the one-way valve 33 on the air inlet pipe 31 of the first annular airbag 11 to inflate the first annular airbag 11, so that the outer side of the first annular airbag 11 contacts and squeezes the inner wall of the intestine 10;

[0040] Similarly, the first intermediate airbag 22 below is inflated, and then the second adjacent annular airbag 11 below is inflated, so that the intermediate airbag 22 can fill the gap between the first annular airbag 11 and the second annular airbag 11, so that after the second annular airbag 11 is inflated, the intermediate airbag 22 can better squeeze the first annular airbag 11, so that the first annular airbag 11 can further squeeze and push the inner wall of the intestine 10, so as to achieve two massages for the same position of the intestine 10;
