How does the Double lumen triple lumen gastric tube play an important role in modern medicine with its unique advantages? ​

1. Material: The key factor that lays the foundation for performance ​
The performance and use experience of the Double lumen triple lumen gastric tube largely depend on the material it uses. At present, silicone, polyurethane and medical-grade polyvinyl chloride are the main materials for making this type of gastric tube. They each have different characteristics to meet diverse clinical needs. ​
Silicone is a widely used material for gastric tubes. Its outstanding advantage lies in its excellent biocompatibility, which almost does not cause immune rejection in the human body, greatly reducing the possibility of adverse reactions such as allergies and inflammation in patients. Silicone is soft and elastic. During insertion and retention, it can fit the complex physiological structure of the human body, reduce friction and damage to the nasal cavity, throat, esophagus and gastric mucosa, and improve patient tolerance. At the same time, silicone has stable chemical properties and good corrosion resistance. It can remain stable in the human body for a long time, ensuring that the gastric tube maintains normal function for a long time and reducing the frequency of replacement. ​
Polyurethane is also a high-quality material for making gastric tubes. It not only has excellent biocompatibility, but also has high strength and toughness. This material has a thin tube wall but can ensure sufficient lumen diameter, which not only meets the needs of nutrient infusion and gastrointestinal decompression, but also makes the gastric tube thinner, making it easier for medical staff to insert it. The good compliance of polyurethane enables it to fit closely to the physiological curvature of the gastrointestinal tract, reducing pressure and damage to tissues. In addition, polyurethane has excellent anti-aging properties and can remain stable in the body environment for a long time, making it suitable for patients who need long-term gastrointestinal support therapy. ​
Medical-grade polyvinyl chloride has also occupied an important position in the production of gastric tubes. It has a relatively low cost and a certain hardness, which facilitates the insertion of gastric tubes. The smooth inner wall of the tube cavity is conducive to the smooth flow of nutrient solution and gastric juice. However, compared with silicone and polyurethane, the biocompatibility of medical-grade polyvinyl chloride is slightly weaker, and long-term use may release chemicals to irritate human tissues. However, with the development of technology, new medical-grade polyvinyl chloride has achieved certain improvements in biocompatibility and flexibility through improved formula.​
The differences in physical properties, chemical stability and biocompatibility of different materials determine the patient groups and clinical scenarios for which they are applicable. For example, for patients who use gastric tubes for a short period of time, medical-grade polyvinyl chloride materials can be selected according to actual conditions; for patients who need to keep gastric tubes for a long time, silicone or polyurethane materials are more suitable. ​
2. Manufacturing process: ingenuity with precision technology ​
The production of double-lumen and triple-lumen gastric tubes involves a variety of precision processes, and each link has strict requirements on product quality and performance. ​
Tube body molding is the first step in production, and extrusion molding is usually used. The polymer material particles are heated to a molten state, and under the push of the screw, they are extruded through a specific mold mouth to form a continuous tubular structure. In this process, parameters such as temperature, pressure and extrusion speed need to be precisely controlled to ensure that the diameter and wall thickness of the tube body are uniform and the surface is smooth. For double-lumen and triple-lumen gastric tubes, the mold design is more complicated, and different material flows need to be separated so that each lumen is independent and tightly combined to ensure that the functions of the lumens do not interfere with each other. ​
The connection and sealing of the lumens are crucial. After the tube body is formed, the lumen interface needs to be finely processed and sealed. Heat sealing technology is a common method, which uses high temperature and pressure to fuse the materials at the interface to form a firm sealed connection. To ensure the sealing, the lumen will also be strictly leak tested, and only products that pass the test can enter the subsequent process. If the lumen is not sealed well, it may cause the nutrient solution to mix with the gastrointestinal contents, affecting the treatment effect, and even causing serious problems such as patient infection. ​
The design and production of the head of the gastric tube should not be ignored. The shape and structure of the head directly affect the ease of insertion and the effect of use. The common round head and bullet head shapes, combined with multiple side holes, are conducive to nutrient solution infusion and gastrointestinal drainage. The head is made using precision processing technologies such as CNC lathes or laser cutting to accurately control the shape, size, number and position of the side holes. Some gastric tubes will also undergo special treatment on the head, such as applying a lubricating coating or covering it with a soft material to further reduce damage to the tissue during insertion. ​
In addition, the identification and installation of the gastric tube's accessories also require delicate operations. Clear scale markings make it easy for medical staff to grasp the insertion depth of the gastric tube and ensure the accurate placement of the gastric tube. The installation of accessories such as connectors and clamps must ensure that the connection is firm and easy to operate. The connector must comply with the general medical interface standards and can be smoothly connected to equipment such as syringes and nutrition infusion pumps; the clamp must have good sealing and operability to facilitate medical staff to control the opening and closing of the tube lumen. ​
III. Use: An important tool to meet diverse clinical needs ​
Double-lumen and triple-lumen gastric tubes are widely used in clinical medicine and play an important role in nutritional support, gastrointestinal decompression and special treatment. ​
In the field of nutritional support, for patients who cannot eat orally or who do not eat enough, such as comatose patients, patients with swallowing dysfunction and patients in intensive care, double-lumen and triple-lumen gastric tubes are important nutrition supply channels. Through nasogastric feeding or gastroenterostomy, one of the tube lumens can be used to directly deliver nutritious liquid food, enteral nutrition preparations, etc. to the patient's stomach or intestines to meet the body's needs for energy and nutrients and maintain normal metabolism and physiological functions. The double-lumen or triple-lumen design can also achieve the simultaneous infusion of different types of nutrient solutions or drugs, avoid interactions, and improve the effect and safety of nutritional support. For example, high-energy nutrient solutions can be infused while drugs that promote digestion can be given to provide patients with comprehensive nutritional support. ​
Gastrointestinal decompression is another important application scenario for double-lumen and triple-lumen gastric tubes. Before and after abdominal surgery, as well as during the treatment of diseases such as intestinal obstruction and gastrointestinal perforation, a large amount of gas and fluid often accumulate in the gastrointestinal tract of patients, causing symptoms such as abdominal distension and abdominal pain, which affects recovery. At this time, using one lumen of the gastric tube to connect a negative pressure suction device can suck out the gas and fluid in the gastrointestinal tract, reduce pressure, relieve discomfort symptoms, and promote the healing of gastrointestinal anastomosis. At the same time, observing the color, nature and amount of the aspirate can provide important basis for medical staff to judge the condition and adjust the treatment plan. For example, if blood appears in the aspirate, it may indicate that there is bleeding in the gastrointestinal tract, and corresponding treatment measures need to be taken in time. ​
In terms of special treatment, double-lumen and triple-lumen gastric tubes also show unique value. When administering drugs to the gastrointestinal tract, the drug can be accurately delivered to the gastrointestinal tract through a specific lumen to improve the efficacy of the drug. For patients who need gastrointestinal lavage, one lumen can be used to inject lavage fluid, and the other lumen can be used to suck out the lavage fluid to achieve gastrointestinal cleaning and treatment. In addition, in scientific research and clinical research, double-lumen and triple-lumen gastric tubes can also be used to collect samples in the gastrointestinal tract, conduct relevant tests and analyses, and provide assistance for medical research and disease diagnosis. ​
Fourth, advantages: significant improvement compared to traditional gastric tubes ​
Compared with traditional single-lumen gastric tubes, double-lumen and triple-lumen gastric tubes have significant advantages in many aspects. ​
The multi-lumen design gives the double-lumen and triple-lumen gastric tubes powerful functional diversity. Traditional single-lumen gastric tubes have a single function and can only perform nutritional infusion or gastrointestinal decompression. The double-lumen and triple-lumen gastric tube can achieve multiple functions at the same time, such as nutritional support and gastrointestinal decompression at the same time, or infuse different nutritional solutions and drugs at the same time, to meet the needs of clinical diversified treatment and improve treatment efficiency and effect. Taking postoperative patients as an example, gastrointestinal decompression can be performed at the same time to promote anastomotic healing, and nutritional infusion can accelerate the recovery process.​
In terms of reducing complications, the double-lumen and triple-lumen gastric tube performs well. The high-quality materials and fine manufacturing process make it less damaging to human tissues during the retention process, reducing the probability of complications such as nasal, throat, esophageal and gastric mucosal damage, ulcers, and infections. The multi-lumen design allows independent infusion of nutrient solution and gastrointestinal decompression, avoiding the risk of aspiration caused by reflux of nutrient solution and the situation of gastrointestinal contents contaminating the nutrient solution, further ensuring patient safety. ​
Patient comfort and tolerance are also the advantages of the double-lumen and triple-lumen gastric tube. The soft material and slender tube body reduce discomfort during insertion and retention, making it easier for patients to accept. The longer retention time reduces the pain caused by frequent replacement of gastric tubes and also reduces the workload of medical staff. In addition, the special design and good compliance of the gastric tube head enable it to better adapt to the physiological structure of the gastrointestinal tract, reduce gastric tube displacement, blockage, etc., and ensure the continuity and effectiveness of treatment. ​
For medical staff, the use of double-lumen and triple-lumen gastric tubes improves work efficiency. Its multi-chamber function and good performance make nutrition support, gastrointestinal decompression and other operations more convenient, and medical staff can complete treatment tasks more quickly and accurately. By observing the aspirate and infusion, it is also convenient to understand the patient's condition in time, adjust the treatment plan, and provide patients with better quality and more efficient medical services.
