Description

Technical Field

[0001] This utility model belongs to the field of gastrointestinal feeding tube technology, specifically relating to a gastrointestinal feeding tube assembly with a flushing function. Background Technology

[0002] A gastrointestinal feeding tube is a medical tube used to provide enteral nutritional support to patients. Gastrointestinal feeding tubes are typically made of flexible medical materials such as silicone, polyurethane, and PVC. They generally consist of a tube body and connectors. The tube body is slender and flexible, allowing it to be easily inserted into the gastrointestinal tract through the nasal cavity or mouth. The connector is used to connect the nutrition delivery device. For patients who, for various reasons, cannot eat normally orally but whose gastrointestinal function is still intact, a gastrointestinal feeding tube can deliver nutrients directly to the stomach or intestines, thereby meeting the patient's nutritional needs. In this way, the patient's metabolism can be maintained, promoting disease recovery or sustaining life.

[0003] When using a gastrointestinal feeding tube, a rigid guidewire is usually inserted inside to facilitate insertion into the patient's stomach or intestines. This increases the insertion force, allowing the tube to pass smoothly through bends in the digestive tract. After insertion, the guidewire is removed. To reduce the number of intubations, the tube is typically left in place. After each nutrient infusion, the tube is flushed with warm water. However, due to the high viscosity of the nutrient solution, residual solution adheres to the inner wall, forming scale. The longer the tube remains in place, the thicker the scale becomes, gradually reducing the passageway and eventually causing complete blockage. Maintaining hygiene within the tube is also difficult. To address the issues of long-term placement and hygiene of gastrointestinal feeding tubes, this invention aims to provide a gastrointestinal feeding tube assembly with a flushing function.

[0012] Preferably, the drain inlet and the flushing head are distributed alternately.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) The present invention provides a gastrointestinal nutrition tube assembly with flushing function, which is equipped with a guide wire. The guide wire is a hollow cavity. After the nutrient solution is infused, the guide wire is placed into the inner cavity of the tube. The operator injects warm water into the guide wire, which can introduce warm water into the main nutrient tube. As the guide wire moves inside the main nutrient tube, it can flush the nutrient solution deposits at specific points.

[0015] (2) The gastrointestinal nutrition tube assembly with flushing function provided by this utility model has a flushing end at the head of the guide wire and a flushing head at the flushing end. The flushing head can flush the inner wall of the nutrition tube, greatly improving the flushing efficiency.

[0016] (3) The present invention provides a gastrointestinal nutrition tube assembly with flushing function. The guide wire in this device is made of materials with high strength and flexibility such as nylon or polypropylene, which can replace ordinary rigid guide wires, so that the device can be smoothly introduced into the human body.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] A gastrointestinal feeding tube assembly with a flushing function includes a main feeding tube 1 and a guidewire 2, which can be inserted into the main feeding tube 1. The guidewire in this device is made of a material with high strength and flexibility, such as nylon or polypropylene, ensuring lubrication while replacing ordinary rigid guidewires, increasing the insertion force of the main feeding tube 1, and allowing the device to be smoothly introduced into the human body. The main feeding tube 1 includes an injection port 3 and a catheter 4, which are fixedly connected. The guidewire 2 includes an injection port 5 and a catheter 6, which are fixedly connected. The diameter of the catheter 6 is smaller than the inner diameter of the catheter 4. To achieve the flushing function of the guidewire 2, the end of the catheter 6 is provided with a flushing tip 7, and the bottom of the flushing tip 7 is closed. Several evenly arranged drainage ports 8 are provided on the side wall of the flushing tip 7. When the operator injects flushing fluid into the guidewire 2, the flushing fluid is discharged from the drainage ports 8. To improve flushing efficiency, several evenly arranged flushing heads 9 are provided on the outer wall of the flushing tip 7. The drainage inlet 8 and flushing head 9 are alternately distributed. During the flushing process, the flushing head 9 directly scrubs the inner wall of the nutrient main tube 1 while the drainage inlet 8 is discharging the flushing fluid. To improve scrubbing efficiency, the width of the flushing end 7 is exactly equal to the inner diameter of the first catheter 4. Based on this, the flushing head 9 is designed in a mushroom shape, including a fixedly connected brush rod 10 and a brush head 11, where the brush head 11 is spherical. To prevent the guidewire 2 from extending beyond the first catheter 4 and excessively irritating the digestive tract wall, this device is designed accordingly for the first catheter 4 and the second catheter 6. The diameter of the second injection port 5 is equal to the inner diameter of the first injection port 3, and the first injection port 3 can be fitted over the second injection port 5. When the first injection port 3 completely covers the second injection port 5, the guidewire 2 reaches its maximum insertion depth, and the end of the flushing end 7 is flush with the end of the first catheter 4.

[0022] When using this device, the operator must first insert it into the human body. During insertion, the operator inserts the guide wire 2 into the main feeding tube 1. At this point, the device is relatively rigid and can be smoothly inserted into the human body. After insertion, the guide wire 2 can be removed for cleaning and reuse. The operator then introduces enteral nutrition solution into the human body through the main feeding tube 1. When it is necessary to flush the main feeding tube 1, the operator inserts the guide wire 2 into the main feeding tube 1, and simultaneously injects warm water into the guide wire 2 during insertion, while simultaneously flushing and brushing the end 7 of the main feeding tube 1.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
