Description

Gastric tube fixing device

Technical Field

The utility model relates to the field of medical instruments, in particular to a gastric tube fixing device.

Background technique

A nasogastric tube is a tube inserted into the stomach through the nasal cavity. It is mainly used to deliver food to the patient's stomach. This method can be used for patients who cannot eat, or to discharge stomach contents to relieve pressure in the stomach.

Inserting a nasogastric tube is a non-invasive procedure, so it is usually fixed with adhesive tape, which has poor stability and usually requires the patient and family members to pay close attention. Avoid pulling when walking, sitting or lying down to prevent the nasogastric tube from coming out. It may enter the trachea by mistake or irritate it, causing choking and suffocation. It will also waste the previous tube insertion operation and require another tube insertion. In order to avoid increasing discomfort to the patient, the nasogastric tube needs to be kept in place during the insertion period.

The existing nasogastric tube fixing device is usually a clamping device designed for the back of the nose, and its structure is usually a tie or nose adhesive tape and a clamping piece for clamping the nasogastric tube. The clamping piece is brought close to the back of the patient's nose by the tie or nose adhesive tape, so that the clamping piece fixes the nasogastric tube at the nostril. The above existing nasogastric tube fixing devices have the following problems:

1. The nasogastric tube is usually fixed on one side of the face, which requires the patient to pay attention to turning over at all times to avoid compression of the tube, which affects the treatment effect of the nasogastric tube. If the patient is awake, the patient can pay attention to the body position to avoid turning over and compressing the tube. However, after the patient falls asleep, he cannot control the natural turning of the body, and the nasogastric tube is still at risk of being compressed.

2. When the tie and the clamp are used together, the tie is fixed to the patient's ear side. When the patient turns over or moves, the tie may fall off or shift, so that the clamp shifts and affects the fixed position of the nasogastric tube.

3. The nose adhesive tape is used in conjunction with the clamp. When the patient tears off the nose adhesive tape, the adhesive tape tears the patient's nose skin, especially for patients with fragile nose skin, which can easily cause redness and stinging of the patient's skin, and the comfort level is low.

Therefore, how to design a gastric tube fixing device that can prevent the nasogastric tube body from being compressed and can be conveniently and stably fixed is a technical problem that needs to be solved.

Utility Model Content

In order to solve the above problems, the purpose of the utility model is to provide a gastric tube fixing device, which solves the problem that the existing nasogastric tube fixation method is unstable and uncomfortable, and the tube body is usually fixed on one side of the face, resulting in the patient being unable to turn over or turning over easily compressing the nasogastric tube.
