Description

Technical Field

[0001] This utility model relates to the field of catheter-type medical device technology, and more specifically to an intestinal decompression tube for insertion into an abdominal wall stoma. Background Technology

[0002] Enterostomy is a surgical treatment for intestinal diseases. It connects the intestine to the abdominal wall through surgery, thereby providing nutritional support, reducing intestinal pressure, and redirecting digestive contents to the normal excretion pathway, restoring normal physiological function. Chinese utility model patent application CN213724317U discloses a T-type enterostomy occlusion tube, including a tube body, an external abdominal wall balloon, and an internal intestinal balloon. It has the advantages of simple and compact appearance, safe and convenient use, and less prone to slippage. It helps to reduce or eliminate the pain of preoperative re-suturing of the intestine. It can also assist in the clinical assessment of the function of the distal intestine, helping to preserve more of the distal intestine during a second surgery.

[0003] However, the inventors discovered that in actual use, after a patient has an enterostomy, intestinal adhesions are likely to occur, and the lower part of the intestine may become dilated and obstructed, which can easily lead to symptoms such as abdominal pain, nausea, and vomiting. In general, the stoma tube may not be able to go down when it encounters intestinal adhesions. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an intestinal decompression tube for insertion into an abdominal wall stoma. The tube is fixed by a posterior and anterior balloon to prevent it from dislodging from the stoma and to prevent reflux. A guide wire is inserted through a ventilation tube interface to pass through intestinal narrowings. A steel ball facilitates tube turning. The first and second side holes facilitate suctioning and flushing of thick feces.

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

[0006] An intestinal decompression tube for insertion into an abdominal wall stoma includes a tube body and a main cavity formed in the middle of the tube body. The top of the tube body has a drainage interface communicating with the main cavity. The drainage interface is sequentially provided with a posterior balloon interface, a ventilation tube interface, and an anterior balloon interface. The tube body has a guidewire channel communicating with the ventilation tube interface, and a guidewire is placed within the guidewire channel. The tube body has a posterior balloon and an anterior balloon communicating with the posterior balloon interface and the anterior balloon interface, respectively. Several first side holes for suctioning and flushing thick feces are provided between the posterior and anterior balloons. Several steel balls are provided on the inner wall of the bottom end of the tube body. The posterior and anterior balloons are used to fix the tube body. The guidewire is used to pass through intestinal stenosis, and the steel balls are used for turning the tube body.

[0007] As a preferred embodiment, a plurality of second side holes are provided between the anterior balloon and the steel ball, and the diameters of the first side holes and the second side holes are both set between 2mm and 4mm. Both the first side holes and the second side holes are connected to the main cavity.

[0008] As a preferred embodiment, the diameter of the anterior balloon is set in the range of 2cm-3cm and the distance from the bottom of the tube is set in the range of 10cm-15cm.

[0009] As a preferred embodiment, the diameter of the posterior balloon is set in the range of 4cm-5cm and the distance from the bottom of the tube is set in the range of 90cm-100cm.

[0010] As a preferred embodiment, the bottom of the tube is configured as a conical annular structure with a length ranging from 5cm to 8cm.

[0011] As a preferred embodiment, the length of the tube is set in the range of 120cm-140cm.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model is equipped with an anterior balloon and a posterior balloon. After the tube body is inserted into the stoma lumen, water or gas is injected into the anterior and posterior balloons through the anterior and posterior balloon interfaces to inflate the balloons. The anterior balloon is placed against the inside of the intestine, and the posterior balloon seals the proximal intestinal segment of the stoma in the abdominal wall. The two balloons are fixed together to prevent the contents of the intestinal segment from being discharged from the proximal fistula.

[0014] 2. This utility model is equipped with a guidewire. When guidewire interventional treatment is required, the guidewire can be inserted into the tube body through the ventilation tube interface and guidewire channel, and exit from the bottom of the tube body, which facilitates the treatment of intestinal stenosis.

[0015] 3. This utility model is also equipped with steel balls. When the bottom of the tube is inserted into the colostomy lumen, the steel balls facilitate the tube to turn, reduce resistance, and make it easier for the tube to bend slightly when it encounters the intestinal wall, guiding the tube to move forward along the intestinal wall.

[0016] In summary, this invention has the advantages of good therapeutic effect and strong practicality, and is suitable for the field of catheter medical device technology. Attached Figure Description

Detailed Implementation

[0022] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0023] Example 1

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0025] like Figures 1 to 3 As shown, an intestinal decompression tube for insertion into an abdominal wall stoma includes a tube body 1 and a main cavity 13 located in the middle of the tube body 1. A drainage port 2, communicating with the main cavity 13, is located at the top of the tube body 1. A posterior balloon port 3, a ventilation tube port 4, and an anterior balloon port 5 are sequentially arranged on the drainage port 2. A guidewire channel 6, communicating with the ventilation tube port 4, is located inside the tube body 1. A guidewire 7 is placed within the guidewire channel 6. The tube body 1 is also equipped with ports for communication with the posterior balloon port 3 and the anterior balloon, respectively. The posterior balloon 8 and the anterior balloon 9 are connected by interface 5. Several first side holes 10 are provided between the posterior balloon 8 and the anterior balloon 9 for aspirating thick feces and flushing. Several steel balls 11 are provided on the inner wall of the bottom end of the tube body 1. The posterior balloon 8 and the anterior balloon 9 are used to fix the tube body 1. The guide wire 7 is used to pass through the intestinal stenosis. The steel balls 11 are used to turn the tube body 1. The tube body 1 is made of silicone. The inner tube is coated with an antibacterial coating and the surface is coated with a hydrophilic coating to reduce intestinal resistance.

[0026] Among them, such as Figure 1 As shown, several second side holes 12 are provided between the anterior balloon 9 and the steel ball 11. The diameters of the first side holes 10 and the second side holes 12 are both set between 2mm and 4mm. The first side holes 10 and the second side holes 12 are both connected to the main body cavity 13. The drainage port 2 is connected to a negative pressure drainage device to suction out thick feces through the first side holes 10 and the second side holes 12. In addition, the intestinal cavity can be flushed through the first side holes 10 and the second side holes 12.

[0027] In addition, such as Figure 1As shown, the diameter of the anterior balloon 9 is set between 2cm and 3cm, and the distance from the bottom of the tube body 1 is set between 10cm and 15cm. The anterior balloon interface 5 is equipped with an anterior balloon valve. In use, after the bottom of the tube body 1 is inserted into the colostomy lumen, gas or water is injected into the anterior balloon 9 through the anterior balloon interface 5, causing the anterior balloon 9 to inflate. The anterior balloon 9 abuts against the inside of the intestine and works with the posterior balloon 8 to fix the tube body 1.

[0028] It is worth mentioning that, such as Figure 2 As shown, the diameter of the posterior balloon 8 is set between 4cm and 5cm, and the distance from the bottom of the tube body 1 is set between 90cm and 100cm. The posterior balloon interface 3 is equipped with a posterior balloon valve. In use, after the bottom of the tube body 1 is inserted into the stoma lumen, gas or water is injected into the posterior balloon 8 through the posterior balloon interface 3, causing the posterior balloon 8 to inflate. The posterior balloon 8 blocks the proximal intestinal segment of the stoma in the abdominal wall. The two balloons are fixed together to prevent the contents of the intestinal segment from being discharged from the proximal fistula.

[0029] Furthermore, such as Figure 3 As shown, the bottom of the tube 1 is set with a conical ring structure and the length range is set between 5cm and 8cm. When encountering intestinal adhesions, it is convenient to insert the tube 1 and reduce resistance. With the help of the steel ball 11, the tube 1 is inserted more smoothly into the stoma lumen. It is convenient for the tube 1 to bend slightly when it encounters the intestinal wall and guide the tube 1 to move forward along the intestinal wall.

[0030] It should be further explained that, such as Figure 1 As shown, the length of tube 1 is set in the range of 120cm-140cm to facilitate surgical operation.

[0031] Work process

[0032] After the bottom of the tube body 1 is inserted into the stoma lumen, gas or water is injected into the anterior balloon 9 through the anterior balloon interface 5, causing the anterior balloon 9 to inflate and abut against the inside of the intestine. Gas or water is injected into the posterior balloon 8 through the posterior balloon interface 3, causing the posterior balloon 8 to inflate. The posterior balloon 8 seals the proximal intestinal segment of the stoma in the abdominal wall. The two balloons are fixed together to prevent the contents of the intestinal segment from being discharged from the proximal fistula. The drainage interface 2 aspirates the thick feces in the intestinal lumen through the first side hole 10 and the second side hole 12. The intestinal lumen can also be flushed through the first side hole 10 and the second side hole 12. When the bottom of the tube body 1 is inserted into the stoma lumen, the steel ball 11 facilitates the turning of the tube body 1, reduces resistance, and guides the tube body 1 forward along the intestinal wall. When interventional treatment is required through the guidewire 7, the guidewire 7 is inserted through the ventilation tube interface 4. The guidewire 7 passes through the guidewire channel 6 and extends from the bottom of the tube body 1 to pass through intestinal stenosis.
