Description

Technical Field

[0001] The utility model relates to the technical field of ostomy tubes, in particular to an improved jejunostomy tube. Background Art

[0002] Esophageal cancer is one of the most aggressive of all gastrointestinal malignancies. Its typical symptom is progressive dysphagia, and its treatment relies on a comprehensive approach, primarily esophagectomy. Esophageal cancer is categorized by anatomical location into cervical, upper thoracic, mid-thoracic, and lower thoracic segments. Surgical treatment requires esophageal incision. Postoperatively, to prevent complications such as anastomotic leakage and infection, patients require prolonged fasting, making nutritional support particularly important.

[0003] Compared with parenteral nutrition, enteral nutrition can significantly reduce the incidence of dysbacteriosis and intestinal dysfunction. Jejunostomy tubes have long been used in my country for enteral nutrition after radical esophagectomy, offering improved clinical efficacy and greater comfort.

[0004] The total length of the jejunostomy tube currently used on the market is 110 cm. The depth of the jejunostomy tube left after esophageal cancer surgery is 30 cm, and the length of the tube exposed at the abdominal wall is 80 cm. After the tube passes through the abdominal wall, it needs to be fixed to the skin of the abdominal wall; the circular hole at the head end of the tube injects nutrient solution into the jejunum, so that the patient can supplement nutrition in time, which helps treatment recovery, but the above scheme still has some room for improvement.

[0005] After clinical use by medical staff, it was found that when the circular hole at the head of the tube was used to inject nutrient solution into the jejunum, the nutrient solution contained some particulate matter, such as minced meat, which easily blocked the circular hole at the head of the tube, making it difficult to inject the nutrient solution into the jejunum, affecting the patient's nutritional supply. Utility Model Content

[0006] In order to solve the above technical problems, the circular hole for nutrient solution at the end of the fistula tube of the present invention is easily clogged by particles. The specific technical solution is as follows:

[0007] A modified jejunostomy tube includes a tube body, which includes a tube body for feeding, the tube body including a feeding section, which is arranged at one end of the tube body; and a discharge hole, which is arranged on the side of the tube body away from the feeding section, so that nutrient solution can flow into the feeding section and flow out of the discharge hole; wherein, the discharge hole is long and strip-shaped along the axis of the tube body.

[0008] Preferably, the discharge area in the middle of the discharge hole is larger than that at both ends thereof.

[0009] Preferably, the discharge hole is a waist-shaped hole, an elliptical hole or a trumpet-shaped hole, and the length direction is along the axis of the tube body.

[0010] Preferably, the discharge hole is located inside the tube body and has an inclination angle.

[0011] Preferably, a threaded section is provided in the middle of the tube body.

[0012] Preferably, the tube body is connected to a cover body at the feeding section, and the cover body can block the opening of the feeding section.

[0013] Preferably, the cover body includes a primary end cover connected to the feed section, and a blocking piece is provided in the primary end cover. The blocking piece can flow into the tube body under the pressure of the nutrient solution and can prevent the nutrient solution in the tube body from flowing back.

[0014] Preferably, the first-level end cover is connected to a second-level end cover that blocks the opening of the first-level end cover.

[0015] It can be seen from the above technical solutions that the present invention has the following beneficial effects:

[0016] The utility model provides a long strip discharge hole at one end of the tube body extending into the jejunum, so that the nutrient solution in the tube body flows into the jejunum from the discharge hole. When the particles in the nutrient solution block the discharge hole, the discharge hole has enough space to allow the particles to flow into the jejunum from the discharge holes at different positions, thereby reducing the risk of blockage.

[0017] The discharge hole can be a waist-shaped hole, an elliptical hole or a trumpet-shaped hole, which can provide a discharge space for the particles in the tube body. If the tube is blocked, as the nutrient solution pushes the particles, and at the same time, the inclination angle is set, the discharge hole is partially opened, further reducing the risk of blockage.

[0021] The following is a detailed description of the present invention in conjunction with the accompanying drawings and specific embodiments. Before describing in detail the technical solutions of each embodiment of the present invention, the nouns and terms involved are explained. In this specification, components with the same name or the same number represent similar or identical structures and are for illustrative purposes only.

[0022] After clinical use by medical staff, the following problems exist: ① The total length of the jejunostomy tube used on the market is 110 cm. The depth of the jejunostomy tube after esophageal cancer surgery is 30 cm, and the length of the tube exposed at the abdominal wall is 80 cm. The excessive length makes fixation inconvenient, the patient's subjective comfort is poor, and the tube is easy to fall off after placement; ② After the tube passes through the abdominal wall, the tube needs to be fixed to the abdominal wall skin. The outer wall of the tube is smooth, and the tube sutures are easy to slide and fall off; ③ The circular hole at the head end of the tube is too small, which can easily cause blockage during nasogastric feeding; ④ The hole for connecting the syringe on the tube mouth cap is open, and nasogastric feeding solution or intestinal contents are easy to reflux from the hole; ⑤ After nasogastric feeding, there is no fixing device at the end of the tube and it is suspended in the abdomen, which makes the patient feel poor and is also easy to cause traction and slippage.

[0023] In response to the above problems, the technical solutions adopted in this application will solve their technical problems one by one.

[0024] like Figure 1 and Figure 2 As shown, an improved jejunostomy tube includes a fistula tube body 10, which includes a tube body 101 for feeding, the tube body 101 includes a feeding section 102 and a discharge hole 104, the feeding section 102 is arranged at one end of the tube body 101; the discharge hole 104 is arranged on the side of the tube body 101 away from the feeding section 102, so that the nutrient solution can flow into the feeding section 102 and flow out from the discharge hole 104; wherein, the discharge hole 104 is long and strip-shaped along the axis of the tube body 101.

[0025] Specifically, the end of the tube body 101 facing the feeding section 102 is open, and the interior thereof can accommodate nutrient solution. After the nutrient solution is injected into the tube body 101 from the feeding section 102, since the end of the tube body 101 located at the discharge hole 104 is located in the jejunum and the end is elliptical, it will not cause stinging to the inner wall of the jejunum. The nutrient solution gradually flows from the tube body 101 to the discharge hole 104 and flows out from the discharge hole 104. Finally, the nutrient solution and particulate matter flowing out of the discharge hole 104 flow into the jejunum to supplement nutrients for the patient. The discharge hole 104 is set to a long strip shape, which helps the nutrient solution flow into the jejunum. At the same time, there is enough space for particulate matter to flow into the jejunum from the discharge holes 104 at different positions, reducing the risk of blockage.

[0026] like Figure 2 As shown, in order to further reduce the risk of tube blockage, the discharge area in the middle of the discharge hole 104 is larger than that at both ends. The design of the discharge hole 104 prevents particles from blocking the tube at both ends of the discharge hole 104. When particles are blocked at both ends of the discharge hole 104, they are pushed by the nutrient solution to make it easier for the particles to flow into the jejunum from the middle area, further reducing blockage.

[0027] Specifically, the discharge hole 104 can be a waist-shaped hole, an elliptical hole or a trumpet-shaped hole, and the length direction is along the axis of the tube body 101. Among them, the waist-shaped hole and the elliptical hole can achieve a larger area in the middle than the two ends, so as to be suitable for the above-mentioned method, and the trumpet-shaped method can make the end with a larger area face the direction of the flow of the nutrient solution, so that the particles flow out from the end with a larger area. In the above-mentioned discharge holes 104 of different shapes, if the pipe is blocked, the end with a larger area of ​​the discharge hole 104 will gradually deform under the push of the nutrient solution, so that it will be partially expanded, which is conducive to the outflow of particles.

[0028] like Figure 2 As shown, the discharge hole 104 is located inside the tube body 101 and is provided with an inclination. During the above process, the inclination can easily squeeze the particles out of the tube body 101 and promote the particles to enter the jejunum.

[0029] like Figure 1 As shown, a threaded section 103 is provided in the middle of the tube body 101, wherein the threaded section 103 is helpful for hanging the suture, and the suture is hung in the groove thereof to prevent the suture from sliding and falling off the tube due to the smooth exterior of the tube body 101.

[0030] like Figure 1 As shown, the tube body 101 is connected to a cover body at the feeding section 102, and the cover body can block the opening of the feeding section 102 to prevent the nasogastric feeding solution or intestinal contents from easily flowing back from the opening.

[0031] Specifically, the cover body includes a first-level end cover 105 connected to the feed section 102, and a blocking piece 107 is arranged in the first-level end cover 105. The blocking piece 107 can flow into the tube body 101 under the pressure of the nutrient solution, and can prevent the nutrient solution in the tube body 101 from flowing back. The first-level end cover 105 is connected to a second-level end cover 106 blocking the opening of the first-level end cover 105, wherein the blocking piece 107 is a cross-shaped plastic part, specifically PVC material. When the nutrient solution is injected into the tube body 101 through the first-level end cover 105, the nutrient solution pushes the blocking piece 107 open. When the nutrient solution is injected, the blocking piece 107 rebounds and seals the port of the first-level end cover 105 to prevent the nutrient solution and particulate matter in the tube body 101 from flowing back.

[0032] like Figure 1 As shown, the tube body 101 is also provided with a groove body for convenient clamping between the feeding section 102 and the threaded section 103. It can adopt the form of an annular fixing ring to facilitate clamping and fixing of the tail, so as to avoid the end of the tube having no fixing device after nasogastric feeding and hanging in the abdomen, which makes the patient feel uncomfortable and is prone to traction and slippage.

[0033] The length of the tube body 101 from one end of the threaded section 103 toward the discharge hole 104 is 30 cm, and the length from the threaded section 103 to the above-mentioned annular fixing ring is 30 cm. This allows the depth of the jejunostomy tube to be placed after esophageal cancer surgery to be 30 cm, and the length of the tube exposed at the abdominal wall to be 30 cm, thereby reducing the total length of the extracorporeal tube and avoiding poor patient comfort and easy tube removal after placement.

[0034] The above-described embodiments are merely descriptions of preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
