Description

TECHNICAL FIELD

[0001] The utility model relates to medical auxiliary equipment technical field, concretely relates to a device capable of fixing nasal feeding tube. BACKGROUND

[0002] Nasal feeding, also known as tube feeding or gastroenteral feeding, is a means of delivering water, nutrients or medication to patients through nasal intubation to the stomach or intestines. It mainly serves patients who cannot eat orally due to various reasons, including those with impaired consciousness, oral and throat diseases, and those who have lost the ability to swallow or chew due to neurological damage. For these patients, the nasal feeding tube becomes an important channel for them to obtain essential nutrients and maintain life. By continuously inputting nutrient solution, it ensures the stability of their basic vital signs.

[0003] Given that the nasal feeding tube can provide patients with the nutrients and therapeutic drugs they need to survive, it is equally important to ensure its stability and prevent it from falling out. Especially when dealing with patients with impaired consciousness, they may unconsciously remove the nasal feeding tube due to discomfort or pressure in the nasal cavity, throat, and stomach caused by the tube. This repeated behavior of removing the nasal feeding tube not only increases the workload of medical staff in repeatedly intubating the tube, but also forces medical institutions to assign dedicated personnel for uninterrupted monitoring to ensure patient safety.

[0004] In the face of the situation where patients with impaired consciousness may remove the nasal feeding tube in a state of impaired consciousness, there are currently some measures to deal with it. The traditional method is to use adhesive tape fixation, which involves crossing the tape in a "Y" shape on the nasal ala and using a high platform method on the cheek for reinforcement. This method is simple to operate and has a low cost. However, its fixation effect mainly depends on the adhesion between the tape and the skin, and this adhesion will weaken with changes in the patient's skin condition (such as increased sweating and oiliness, causing the tape to gradually loosen and fall off), thus there is a problem of unstable fixation, which can easily fall off when the patient pulls the nasal feeding tube. Another method is to use a restraint belt to fix the patient's upper limbs, directly preventing the patient's hands from contacting the nasal feeding tube by limiting their upper limb movement. Although this method can completely prevent the nasal feeding tube from being pulled out, it may cause the patient to feel restricted and uncomfortable, and long-term use of the restraint belt can cause skin pressure, pain, redness, and even pressure sores and other skin problems.

[0005] Therefore, it is particularly urgent and important to develop a fixation device that can stably fix the nasal feeding tube, ensuring that patients can safely and stably receive nasal feeding nutrition support. SUMMARY
