Product advantages and characteristics of nasal feeding silicone straw (nasal feeding tube)
Advantages of core products
1. Excellent biocompatibility and high safety
It is made of medical-grade silicone material, which meets USP Class VI and other medical certification standards. It is extremely irritating to the nasal cavity, oesophagus and gastric mucosa, and reduces inflammation, ulcers and other adverse reactions caused by long-term retention. It is suitable for patients who need long-term nasal feeding such as coma and swallowing disorders.
2. Stable physical performance, adaptable to clinical needs
It is both flexible and tough, easy to bend and fit the physiological channel when inserted, reducing the risk of operating damage; at the same time, it has strong temperature resistance (can withstand 121℃ high-temperature sterilisation), and is not easily corroded by nutrient solution and drugs, and the service life is longer than that of ordinary rubber or plastic nasal feeding tubes.
3. Easy to operate, accurate and controllable
The transparency of the tube wall is high, which can clearly observe the flow of nutrient solution in the tube and whether there is blockage or residue; the tube body is marked with a clear scale (such as a scale per centimetre), which is convenient for medical staff to accurately control the insertion depth (adults usually insert 45-55cm) to ensure that the end is in the appropriate position in the stomach.
Product feature design
1. Anti-backflow and anti-blocking structure
◦ Some models are equipped with a "side hole + top opening" double hole design at the end, which reduces nutrient solution adhesion and blockage, while reducing the local pressure on the stomach wall;
◦ High-end products are equipped with anti-reflux valves to prevent gastric contents from flowing back to the oesophagus and reduce the risk of false aspiration and aspiration pneumonia.
2. Optimisation of fixing and connection
The outer end of the tube is designed with an anti-slip fixed wing or tape pasting area, which can be firmly fixed on both sides of the nasal wing to prevent the catheter from shifting and escaping when the patient is moving; the connecter adopts a standardised Ruhr interface, which can stably connect syringes, nasal feeding pumps and other equipment to avoid leakage during infusion.
3. Customised adaptive design
◦ Classified according to the pipe diameter (such as 6Fr, 8Fr, 10Fr, etc.), the suitable model can be selected according to the patient's age (adult/child/infant) and condition (such as thin tube diameter for patients with oesophageal stenosis);
◦ Some products are "tranasal cerenal tube", and the end can enter the kerenum through the pylorus. It is suitable for patients with insufficient gastric power and prone to reflux, reducing the risk of gastric retention.
4. Sterile independent packaging, ready to use
Single independent sterile packaging, sterilised by epoxy ethane, can be opened and used directly without additional disinfection, meeting the requirements of clinical sterile operation and reducing the probability of cross-infection.
Characteristics of clinical application value
• Good tolerance for long-term retention: Compared with plastic nasal feeding tubes, the silicone material is soft and not easy to harden, and the patient's wearing comfort is higher, which can reduce irritability and tube pulling behaviour caused by catheter irritation.
• Strong compatibility: It can be adapted to a variety of dosage forms of nutrient solutions (such as intestinal nutritional preparations, homogenisation) and liquid drugs, and does not react chemically with common drugs to ensure the safety of medication.
FAQ:
Nasal feeding silicone straw (nasal feeding tube) frequently asked questions and answers
1. What should I do if the patient has nasal/oesophageal mucosal injury and bleeding?
Stop using it immediately and pull out the nasal feeding tube, press the bleeding site with clean gauze to stop bleeding; contact the medical staff in time to assess the degree of injury, and apply local medicine if necessary. The next time you insert it, choose a finer model with a softer texture, apply a medical lubricant, slow down the action and advance along the physiological curvature of the nasal cavity.
2. What should I do if the nasal feeding tube is blocked and the nutrient solution cannot be pushed?
First, try to flush the tube slowly with 20-30ml of warm boiled water (do not use violent injection); if the blockage is serious, you can soak it with a small amount of sodium bicarbonate solution or pancreatic enzyme solution for 15-20 minutes before rinsing; in daily life, you need to flush the tube with warm water before and after each feeding to avoid residual coagulation of the nutrient solution.
3. What are the reasons for vomiting, bloating and reflux in patients during nasal feeding?
It may be caused by too fast feeding, too much single dose or insufficient gastric motility of the patient. The infusion rate should be slowed down (recommended to be 100-150ml per hour), reduce the amount of single feeding, and keep the patient in a semi-recumbent position for 30-60 minutes after feeding; if there is frequent reflux, you need to contact the doctor to adjust the type of nutrient solution or use gastric motonic drugs.
4. How to solve the problem of frequent displacement or prolapse if the nasal feeding tube is not firmly fixed?
Use medical adhesive tape to stick to the nose wing and cheeks by "Y" or "work" fixation, and change the tape regularly (24 hours/time in summer, 48 hours/time in winter); if the patient is easy to scratch, you can wear restraining gloves and strengthen care at the same time. After displacement, the medical staff needs to confirm the position (such as pumping gastric juice, listening to the sound of gas and water), and cannot be reinserted by yourself.
5. There is a strange smell or dirt on the inner wall of the nasal feeding tube. How to clean and disinfect it?
The nasal feeding tube is a disposable consumable (short-term tube for 7-14 days, long-term tube for 30-90 days). Repeated disinfection and use are prohibited. If there is odour or dirt, a new tube needs to be replaced. In daily life, you only need to flush the tube with warm water, and detergents or disinfectants are not used to avoid chemical residues from stimulating the digestive tract.
6. What should I do if the patient has a strong sense of discomfort and frequent restlessness and resistance to the nasal feeding tube?
Communicate and explain to sober patients to distract them; choose a transnasal jejenum tube to replace the gastric tube (less irritation to the throat), or use a small amount of sedative drugs under the guidance of a doctor; try to hide the tube when fixed to reduce the patient's visual discomfort.
7. After the nasal feeding tube is inserted, how to confirm whether it is in the stomach (not the trachea)?
Preferred method: use a syringe to extract gastric juice (pale yellow or grass green); auxiliary method: place the stethoscope under the synoid, quickly inject 10-20ml of air, and listen to whether there is "the sound of gas passing through water"; if the extracted solution is colourless and transparent (may be in the trachea), it should be pulled out immediately and let the patient absorb oxygen, and contact the medical staff.
8. What should I do if the temperature of the nutrient solution is too low during the nasal feeding process, causing diarrhoea in the patient?
Before feeding, heat the nutrient solution in a 38-40℃ warm water bath (microwave heating is prohibited). It is better to use a nasal feeding pump with heating function; when diarrhoea has occurred, stop feeding and contact the doctor, and adjust the temperature and concentration of the nutrient solution after the symptoms are relieved.
9. How to deal with the damage and leakage of the end connecter of the nasal feeding tube, which affects the use?
If the connecter is slightly damaged, it can be temporarily wrapped and sealed with medical sterile tape (emergency only); if the damage is serious, the new tube should be replaced immediately, and it should not continue to be used to avoid nutrient solution contamination or inaccurate push.
10. How to prevent oral ulcers and nasal pressure sores in patients with long-term use of nasal feeding tubes?
Clean the nasal cavity and oral cavity with physiological saline twice a day, and apply medical Vaseline to protect the mucous membrane in the nasal cavity; loosen the nasal feeding tube regularly (every 2-4 hours) and change the fixed position to avoid local long-term pressure; evaluate every week whether the feeding method can be adjusted (such as changing to percutaneous endoscopic gastric fistula).
