Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a decompression-type jejunal feeding tube. Background Technology

[0002] Decompression jejunal feeding tubes are a medical procedure used to decompress the gastrointestinal tract and provide nutritional support. In some cases, such as gastrointestinal obstruction, severe gastrointestinal dysfunction, or during postoperative recovery, patients may be unable to eat normally or need to reduce pressure on the gastrointestinal tract. In these situations, a feeding tube is usually required.

[0003] Currently, doctors can insert a feeding tube through the nostril, through the esophagus and stomach, and finally to the jejunum (nasojejunal tube). Nutrients can be delivered directly to the jejunum (part of the small intestine) through the feeding tube to ensure that patients receive adequate nutritional support and to alleviate symptoms such as stomach bloating and other discomfort.

[0004] However, in actual use, in order to achieve gastrointestinal decompression and nutritional supply, it is often necessary to insert multiple tubes. This not only increases the complexity of the operation, but also brings additional physical burden and discomfort to the patient. Moreover, after the tubes are inserted, the front end of the tube hangs outside the patient's nose and is unstable. This not only makes the patient feel a sense of heaviness, but also makes the tubes prone to displacement and affect the effectiveness of use. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the existing technology where multiple tube insertions increase the complexity of operation and the burden on patients, and the externally suspended tubes are not stable enough, easily causing a feeling of heaviness and displacement, thus affecting the effectiveness of use. Therefore, a decompression-type jejunal feeding tube is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A decompression-type jejunal feeding tube includes an intestinal tube and a feeding tube fixedly connected within the intestinal tube, wherein the end of the feeding tube extends outward along the axis of the intestinal tube, and the intestinal tube is provided with a branch tube for decompression of the gastrointestinal tract and supplying nutrients into the feeding tube; a plurality of elastic plates are installed on the intestinal tube, wherein a ring is slidably fitted on the intestinal tube, and the plurality of elastic plates are fixedly connected in a ring on the ring, with adjacent elastic plates forming a gap and enclosing a conical channel, and a fastening sleeve is slidably connected to the intestinal tube, such that when the fastening sleeve is inserted into the conical channel, the plurality of elastic plates will expand outward along the axis of the ring and fit tightly against the patient's nasal cavity.

[0008] For gastrointestinal decompression and nutrition provision, preferably, the branch fitting includes a negative pressure connector fixedly connected to the front end of the intestinal tube, and a nutrition connector connected to the feed tube is fixedly connected to the front end of the intestinal tube. A decompression hole is provided through the end of the intestinal tube, and a feed hole is provided through the end of the feed tube.

[0009] To further protect the nutrient inlet and the negative pressure inlet, a tube plug is inserted into the port of both the nutrient inlet and the negative pressure inlet.

[0010] To ensure the biocompatibility and flexibility of the feeding tube, preferably, the intestinal tube and the delivery tube are made of silicone or rubber.

[0011] To facilitate the smooth insertion of the feeding tube into the patient's body, preferably, both the intestinal tube and the feeding tube have rounded corners at their ends.

[0012] In order to generate a damping force between the fastening sleeve and the intestinal tract, preferably, the inner diameter of the fastening sleeve is smaller than the diameter of the intestinal tract.

[0013] In order for the fastening sleeve to slide over and compress the inclined surface of the elastic plate, preferably, the elastic plate has an outer inclined surface and an inner inclined surface, and the included angle between the outer inclined surface and the inner inclined surface and the horizontal plane is 20°-30°.

[0014] To improve the tightness of the connection between the fastening sleeve and the elastic plate, preferably, the fastening sleeve is provided with multiple anti-slip grooves, and the multiple anti-slip grooves are equidistantly distributed on the circumferential surface of the fastening sleeve.

[0015] To facilitate the application of force to push and pull the fastening sleeve, preferably, both sides of the fastening sleeve are fixedly connected with pull blocks, and the pull blocks and the fastening sleeve are integrally formed.

[0016] To ensure effective fixation of the feeding tube and patient comfort, the elastic plate is preferably made of polyurethane.

[0017] Compared with the prior art, this utility model provides a decompression-type jejunal feeding tube, which has the following beneficial effects:

[0018] 1. This decompression-type jejunal feeding tube, through its integrated intestinal tube and feeding tube design, can decompress the patient's gastrointestinal tract and provide nutritional support without the need for inserting multiple tubes, which not only reduces the complexity of operation but also reduces the physical burden and discomfort on the patient.

[0019] 2. This decompression-type jejunal feeding tube, through the combination of a ring, an elastic plate, and a fastening sleeve, can directly insert and fix the intestinal tube located outside the nose into the patient's nostril.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] Example:

[0029] Reference Figures 1-4 This utility model embodiment provides a decompression-type jejunal feeding tube, including an intestinal tube 1, and further including:

[0030] A feeding tube 2 is fixedly connected inside the intestinal tube 1; wherein, the end of the feeding tube 2 extends outward along the axis of the intestinal tube 1, and the intestinal tube 1 and the feeding tube 2 are made of silicone or rubber. Such materials can ensure the biocompatibility and softness of the feeding tube, reduce irritation to the patient's mucosa, and make the feeding tube suitable for long-term indwelling.

[0031] The intestinal tube 1 is equipped with a branch tube, which is used for decompression of the gastrointestinal tract and for supplying nutrients to the feeding tube 2. Both the ends of the intestinal tube 1 and the feeding tube 2 are rounded. This design makes the ends of the intestinal tube 1 and the feeding tube 2 more rounded, which makes it easier to insert the feeding tube into the patient's body smoothly.

[0032] Multiple elastic plates 8 are installed on the intestinal tube 1. A ring 7 is slidably sleeved on the intestinal tube 1. The multiple elastic plates 8 are fixedly connected to the ring 7 in a ring shape, and the adjacent elastic plates 8 form a gap and surround a conical channel. The elastic plates 8 are made of polyurethane, which can maintain good elasticity, flexibility and support strength within a wide range of hardness, which can ensure the fixation effect of the elastic plates 8 on the feeding tube and the patient's comfort.

[0033] A fastening sleeve 9 is slidably connected to the intestinal tube 1. When the fastening sleeve 9 is inserted into the conical channel, multiple elastic plates 8 will expand outwards along the axis of the ring 7 and fit tightly against the patient's nasal cavity. The number of elastic plates 8 is 6-10, preferably 8 in the jejunal feeding tube. The inner diameter of the fastening sleeve 9 is slightly smaller than the diameter of the intestinal tube 1, which can generate a damping force between the fastening sleeve 9 and the intestinal tube 1, making it easier for the fastening sleeve 9 to position the intestinal tube 1.

[0034] Specifically, during use, the combination of the intestinal tube 1, the feeding tube 2, and the branch fittings can reduce the pressure on the patient's gastrointestinal tract and provide nutritional support. The combined design of the intestinal tube 1 and the feeding tube 2 eliminates the need to insert multiple tubes, reducing operational complexity and the patient's physical burden and discomfort. Furthermore, the combination of the ring 7, the elastic plate 8, and the fastening sleeve 9 allows the intestinal tube 1, located outside the nose, to be directly inserted and fixed inside the patient's nostril. The assembly and disassembly operations are very convenient, and the tube can be fixed in one go, greatly improving the stability of the feeding tube's tip and preventing the feeding tube from feeling heavy or shifting, thus ensuring its effectiveness.

[0035] The decompression-type jejunal feeding tube includes a negative pressure connector 6 fixedly connected to the front end of the intestinal tube 1. The front end of the intestinal tube 1 is fixedly connected to a feeding connector 5 connected to the feeding tube 2. A decompression hole 3 is provided through the end of the intestinal tube 1, and a feeding hole 4 is provided through the end of the feeding tube 2. Tube plugs 12 are inserted into the ports of the feeding connector 5 and the negative pressure connector 6 to shield and protect the feeding connector 5 and the negative pressure connector 6.

[0036] Specifically, during use, the negative pressure tube 6 is connected to the negative pressure device, which can generate negative pressure in the intestinal tract 1. This allows gas or liquid in the stomach and intestines to be drawn into the intestinal tract 1 through the decompression hole 3 and discharged through the negative pressure tube 6. This can reduce the pressure on the patient's stomach and intestines, thereby alleviating gastric bloating and other discomfort symptoms. Furthermore, through the setting of the nutrition tube 5, nutrients can be injected into the infusion tube 2 using a syringe or other tools and delivered into the patient's jejunum through the infusion hole 4, ensuring that the patient can receive sufficient nutritional support.

[0037] The aforementioned elastic plate 8 has an outer inclined surface and an inner inclined surface, and the angle between the outer inclined surface and the inner inclined surface and the horizontal plane is 20°-30°. Here, it is preferred that they are both 26° to ensure their covering and clamping effect.

[0038] Specifically, this design allows the fastening sleeve 9 to slide over and press against the inclined surface of the elastic plate 8, causing the elastic plate 8 to expand outwards under the pressure.

[0039] The fastening sleeve 9 is provided with a plurality of anti-slip grooves 10, and the plurality of anti-slip grooves 10 are equidistantly distributed on the circumferential surface of the fastening sleeve 9. The number of anti-slip grooves 10 is 10 to 20, and preferably 15 in this jejunal feeding tube.

[0040] Specifically, by setting the anti-slip groove 10, the friction can be increased and the tightness of the connection between the fastening sleeve 9 and the elastic plate 8 can be improved, thereby ensuring the fixing effect of the nutrient tube.

[0041] Pull blocks 11 are fixedly connected to both sides of the fastening sleeve 9, and the pull blocks 11 and the fastening sleeve 9 are integrally formed.

[0042] Specifically, the pull block 11 facilitates the application of force to push and pull the fastening sleeve 9.

[0043] During the nasogastric feeding procedure, the intestinal tube 1 and the feeding tube 2 are first inserted through the patient's nostril. The feeding tube 2 passes through the esophagus, stomach, and finally reaches the jejunum, while the intestinal tube 1 is located in the stomach. At this time, the medical staff should hold the front end of the intestinal tube 1 and push the ring 7 and the elastic plate 8. Then, the multiple conical elastic plates 8 are inserted into the patient's nostril. Next, the intestinal tube 1 is slightly flattened and bent to create a gap between the intestinal tube 1 and the fastening sleeve 9, preventing excessive resistance between the fastening sleeve 9 and the intestinal tube 1 from sliding. Then, the fastening sleeve 9 is slid into the conical channel of the elastic plate 8 and the inclined surface of the elastic plate 8 is squeezed, which can make the multiple elastic plates 8 open outwards and fit tightly against the patient's nasal cavity. Then, the intestinal tube 1 is released to restore it and fit tightly against the fastening sleeve 9, thus completing the fixation of the feeding tube.

[0044] With the cooperation of the ring 7, the elastic plate 8 and the fastening sleeve 9, the intestinal tube 1 located outside the nose can be directly inserted and fixed into the patient's nostril. The disassembly and assembly operations are very convenient, and the tube can be fixed in one go, which greatly improves the stability of the front end of the feeding tube and makes the feeding tube less likely to cause a feeling of heaviness and displacement.

[0045] Furthermore, during use, by connecting the negative pressure connector 6 to the negative pressure device, negative pressure can be generated in the intestinal tract 1, allowing gas or liquid in the stomach and intestines to be drawn into the intestinal tract 1 through the decompression hole 3 and discharged through the negative pressure connector 6. This can reduce the pressure on the patient's stomach and intestines, thereby alleviating gastric bloating and other discomfort symptoms. In addition, the above technical solution, through the setting of the nutrition connector 5, can use a needle or other tools to inject nutrients into the infusion tube 2 and deliver them into the patient's jejunum through the infusion hole 4, ensuring that the patient can receive sufficient nutritional support. Through the two-in-one tube design, there is no need to insert multiple tubes, which not only reduces the complexity of operation, but also reduces the physical burden and discomfort of the patient.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
