Description

Technical Field

[0001] The utility model relates to the technical field of gastric tubes, in particular to a gastric tube which is anti-falling and can provide gastrointestinal decompression. Background Art

[0002] A gastric tube is a medical device, usually made of medical polymer materials (such as polyurethane, etc.), and has a slender tubular structure. It is mainly used to be inserted into the stomach through the nasal cavity or oral cavity to achieve various medical purposes. For patients who require long-term gastrointestinal decompression, such as some patients with chronic intestinal obstruction, good fixation of the gastric tube is very important. If the gastric tube falls off frequently, repeated intubation is required, which will not only increase the patient's pain, but may also damage the nasal cavity, throat and esophageal mucosa.

[0003] During the actual use of the gastric tube, the length of the part reserved outside the human body is relatively long. Due to the long exposed part, it is easy to be caught by other objects, causing the tube to fall off. Re-inserting the gastric tube will bring more pain to the patient and increase the workload of medical staff.

[0004] The existing patent (publication number: CN212038283U) discloses an anti-falling gastric tube, which includes a tube body, a plurality of side holes are opened at the lower end of the tube body, and an external joint is arranged at the upper end, wherein a bending portion generating component for bending the tube body to form an arc-shaped bending portion that can be hung on the patient's ear is arranged at a position close to the external joint on the tube body. The anti-falling gastric tube shortens the length of the part exposed outside the patient's body by adding a bending portion generating component to the tube body, and the upper end of the tube body is hung on the patient's ear through the arc-shaped bending portion, which can effectively prevent the gastric tube from being caught by other objects and causing the tube to fall off, thereby avoiding reinsertion of the gastric tube, reducing the workload of medical staff, and having a simple structure, easy to implement, and convenient to operate.

[0005] In view of the above problems, existing patents have provided solutions. However, most existing gastric tubes are fixed to the nose wings with adhesive tape, which may cause the gastric tube to fall off due to factors such as reduced viscosity of the adhesive tape and patient activity. In addition, the traditional fixed negative pressure suction method of the gastric tube may easily cause damage to the gastrointestinal tract due to improper suction, or the decompression effect may be poor in some cases.

[0006] Therefore, a gastric tube which is prevented from falling off and can provide gastrointestinal decompression is proposed. Utility Model Content
