Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a detachable double-lumen gastrojejunal feeding tube. Background Technology

[0002] In today's ever-advancing and developing medical field, the design and application of medical devices increasingly focus on improving patient experience and treatment outcomes. For patients undergoing upper gastrointestinal surgery, especially Billroth II gastrectomy, early postoperative nutritional support is one of the key factors in ensuring a smooth recovery. Due to the anatomical changes caused by surgery, patients are often unable to eat directly and therefore require external devices for gastrointestinal decompression and enteral nutrition.

[0003] In traditional methods, feeding tubes and negative pressure tubes are often inserted through the nose to deliver enteral nutrition and relieve gastrointestinal decompression, respectively. However, if both tubes are inserted through the same nostril, it not only significantly increases patient discomfort but may also damage the nasal mucosa due to local pressure, potentially affecting the patient's tolerance to long-term tube placement. To avoid this problem, clinical practice often involves inserting the feeding tube and negative pressure tube through separate nostrils. However, while this approach alleviates local pressure to some extent, it results in the patient experiencing the discomfort of inserting tubes twice, and because both nostrils are occupied, it further restricts the patient's respiratory function, increasing the risk of respiratory distress.

[0004] Therefore, there is an urgent need for a new type of medical device that can balance patient comfort, therapeutic efficacy, and safety. To this end, a separable double-lumen gastrojejunal feeding tube is proposed. This innovative double-lumen design integrates nutrient delivery and gastrointestinal decompression functions into a single tube, and optimizes its insertion method, thereby effectively solving the aforementioned problems and improving the overall perioperative experience and recovery outcomes for patients. Utility Model Content

[0005] To address the aforementioned issues, this invention provides a detachable double-lumen gastrojejunal feeding tube. This detachable double-lumen gastrojejunal feeding tube significantly improves the patient's perioperative experience and treatment outcomes by reducing patient discomfort, lowering the risk of local compression, and improving respiratory function.

[0006] The technical solution of this utility model is as follows:

[0007] A separable double-lumen gastrojejunal feeding tube includes a feeding tube, a negative pressure tube, and an integrated feeding and negative pressure tube. The feeding tube consists of a feeding tube front end and a feeding tube rear end. The feeding tube front end and the upper middle section of the negative pressure tube are located inside the integrated feeding and negative pressure tube. The feeding tube front end and the negative pressure tube are separated at their lower ends. The feeding tube front end and the negative pressure tube upper end are respectively provided with a feeding tube inlet and a negative pressure tube inlet. An air vent is provided at the lower end of the feeding tube rear end, and a negative pressure hole is provided at the lower part of the negative pressure tube. The bottom of the negative pressure tube is a blind hole.

[0008] The length of the tip of the feeding tube is 100cm and the outer diameter is 7fr.

[0009] The length of the rear end of the nutrient tube is 50cm, and the outer diameter is 14fr.

[0010] A transition slope is provided at the junction of the front and rear ends of the feeding tube.

[0011] The feeding tube contains a guide wire.

[0012] The inside of the feeding tube is lined with a developing coating.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model discloses a separable double-lumen gastrojejunal feeding tube, which significantly improves the patient's perioperative experience and treatment effect by reducing patient discomfort, lowering the risk of local compression, and improving respiratory function.

[0015] 2. This utility model discloses a separable double-lumen gastrojejunal feeding tube, which reduces discomfort: Traditional feeding tubes and negative pressure tubes usually need to be inserted through two separate nasal cavities, which causes patients the discomfort of inserting the tube twice; while the separable double-lumen gastrojejunal feeding tube cleverly combines the feeding tube and negative pressure tube into an integrated feeding and negative pressure tube, and is inserted through a single nasal cavity; this design greatly reduces the number of tube insertions and discomfort for patients, and improves patient comfort.

[0016] 3. The present invention discloses a separable double-lumen gastrojejunal feeding tube, which reduces the risk of local compression: since both tubes are inserted through the same nasal cavity, the situation of both nasal cavities being occupied is avoided, thereby reducing pain and discomfort caused by local compression; at the same time, it also reduces the risk of nasal mucosal damage and infection caused by long-term tube insertion.

[0017] 4. The present invention discloses a separable double-lumen gastrojejunal feeding tube, which improves respiratory function: In traditional methods, both nasal cavities are occupied, which will greatly affect the patient's breathing; while the design of the separable double-lumen gastrojejunal feeding tube ensures that at least one nasal cavity is open, thereby ensuring the patient's normal respiratory function and reducing the risk of breathing difficulties and suffocation.

[0018] 5. This utility model discloses a separable double-lumen gastrojejunal feeding tube, which improves the efficiency of nutritional support: the design not only reduces patient suffering but also improves the efficiency of nutritional support; the independent design of the feeding tube tip and the negative pressure tube allows the delivery of nutrient solution and intestinal decompression to be carried out simultaneously or separately without interference; this flexibility helps doctors to develop personalized nutritional support plans according to the patient's specific condition and accelerate the patient's recovery process.

[0019] 6. This utility model discloses a separable double-lumen gastrojejunal feeding tube, which is easy to operate and monitor: the design of the rear end of the feeding tube, such as the vent hole and the transition slope of the feeding tube, as well as the negative pressure hole and the bottom of the blind hole of the negative pressure tube, makes the operation and monitoring of the tube more convenient; at the same time, the built-in guide wire and the contrast coating further improve the accuracy of tube placement and visibility under imaging examination, providing doctors with more convenience and protection.

Detailed Implementation Example

[0027] like Figure 1 As shown, the separable double-lumen gastrojejunal feeding tube includes a feeding tube 1, a negative pressure tube 2, and an integrated negative pressure feeding tube 3. The feeding tube 1 consists of a feeding tube front end 11 and a feeding tube rear end 12. The upper and middle sections of the feeding tube front end 11 and the negative pressure tube 2 are located inside the integrated negative pressure feeding tube 3. The feeding tube front end 11 and the negative pressure tube 2 are separated at their lower ends. The feeding tube front end 11 and the negative pressure tube 2 are respectively provided with a feeding tube inlet 111 and a negative pressure tube inlet 21 at their upper ends. An exhaust port 122 is provided at the lower end of the feeding tube rear end 12. A negative pressure hole 22 is provided at the lower part of the negative pressure tube 2. The bottom 23 of the negative pressure tube 2 is a blind hole.

[0028] The feeding tube tip 11 is 100cm long and has an outer diameter of 7fr. The outer diameter fr is a common size designation in the medical field, especially for catheter-related products. fr is an abbreviation for French, originally a unit used to measure catheter circumference, but it has gradually evolved to directly represent an approximate value for the catheter's outer diameter. Specifically, 1 fr is approximately equal to 1 / 3 millimeter of the catheter's outer diameter.

[0029] The fr unit was invented by a French physician to measure the outer diameter of catheters. Originally a unit for measuring circumference, it is often used in practice to approximate the diameter of catheters because of the fixed mathematical relationship between circumference and diameter (circumference = π × diameter).

[0030] The length of the rear end 12 of the nutrient tube is 50cm, and the outer diameter is 14fr.

[0031] like Figure 2 As shown, a transition slope 121 for the nutrient tube is provided at the junction of the front end 11 and the rear end 12 of the nutrient tube.

[0032] like Figure 3 As shown, a guide wire 4 is provided inside the nutrient tube 1; a developing coating 5 is provided inside the nutrient tube 1. Example

[0033] A detachable double-lumen gastrojejunal feeding tube is used in gastroenterology. It includes an integrated feeding and negative pressure tube, a feeding tube, a negative pressure tube, and a guidewire. In cases of Biro II-style partial gastrectomy, the integrated feeding and negative pressure tube is a single, dual-core tube, comprising both a feeding tube section and a negative pressure tube section. Its cylindrical structure facilitates insertion. The feeding tube is made of TPU with a radiopaque coating on the inner side, allowing for placement via X-ray imaging. Specifically, the feeding tube is 100cm long with an outer diameter of 7fr at the front end, transitioning to a 50cm long feeding tube with an outer diameter of 14fr at the rear end. The bottom of the rear end of the feeding tube has a through-hole, and five vent holes are attached to its upper side. After the nutrient solution enters the feeding tube, it flows into the intestine through the through-hole at the bottom of the feeding tube, and the five vent holes expel excess gas from the tube.

[0034] The negative pressure tube is made of TPU with an outer diameter of 6Fr. Its bottom reaches the stomach, and there are five negative pressure holes on the upper side of the bottom of the tube, which help to empty the stomach and reduce pressure. The guidewire is located within the feeding port and guides the feeding tube.

[0035] After Biro II gastrectomy, the double-lumen gastrojejunal feeding tube can deliver nutrition to the intestines and empty and decompress gastric juices, mainly solving the problem of significant discomfort caused by two tubes being inserted into the nostrils at the same time.

[0036] The separable double-lumen gastrojejunal feeding tube includes a feeding tube, a negative pressure tube, an integrated feeding and negative pressure tube, and a guidewire. The double-lumen gastrojejunal feeding tube has both a feeding tube to deliver nutrition and a negative pressure tube to empty and depressurize. The double-lumen gastrojejunal feeding tube is an integrated dual-core tube that enters the gastrointestinal tract through one nostril.

[0037] The bottom of the negative pressure tube is a blind hole, and there are a certain number of negative pressure holes on the upper side near the bottom to empty and depressurize the stomach fluid.

[0038] The feeding tube has a small outer diameter at the tip. After entering the nasal tube, it forms an integrated feeding and negative pressure tube with the negative pressure tube. The integrated feeding and negative pressure tube is cylindrical in shape, which makes it easy to enter the body through the nasal tube. The tip of the feeding tube transitions to the rear end through the inclined surface of the feeding tube. The outer diameter of the feeding tube is 14Fr. The tip of the feeding tube reaches the stomach, and the rear end of the feeding tube reaches the intestine from the stomach.

[0039] The feeding tube and the negative pressure tube are merged at the junction to form an integrated feeding and negative pressure tube. The length of the feeding and negative pressure tube extends from the junction to the separation point of the two tubes.

[0040] The bottom of the nutrient tube is a through hole, and there are a certain number of vent holes on the side above the bottom outlet of the nutrient tube, which serve to release excess gas from the pipe and facilitate the discharge of nutrient solution from the bottom of the nutrient tube.

[0041] After the negative pressure tube enters the stomach, it is detached from the feeding tube by tearing along the separation line.

[0042] The guidewire inside the feeding tube serves to guide the double-lumen gastrojejunal feeding tube into the stomach and intestines.

[0043] The inside of the feeding tube has a radiopaque coating, which can accurately guide the double-lumen gastrojejunal feeding tube to the designated position under X-ray irradiation.
