Three-cavity gastric tube with balloon

Abstract

The invention discloses a three-cavity gastric tube with a balloon, and relates to the field of medical apparatuses. The three-cavity gastric tube with the balloon comprises a main tube body, the main tube body comprises a main cavity, an auxiliary cavity and a balloon cavity, the top end of the main cavity is connected with a main cavity tube head, the top end of the auxiliary cavity is connected with an auxiliary cavity tube head, the top end of the balloon cavity is connected with a balloon cavity tube head, the bottom end of the balloon cavity is communicated with the balloon, the bottom end of the main tube body is provided with a blind end, and the balloon cavity tube head is provided with a bidirectional valve. According to the three-cavity gastric tube with the balloon, the main tube body is provided with the fixed balloon, after the main tube body enters the body of a patient, inflation or water filling is conducted, a cardia opening is stuck, in-vivo fixation is conducted, the main tube body does not slip from the body, and reflux of content in the stomach is prevented; through the arrangement of the bidirectional valve on the balloon cavity tube head, gas or water in the fixed balloon is pumped, and the gastric tube is conveniently taken out. Meanwhile, through the design of a three-cavity structure, the pressure reduction and attraction effects of the gastric tube are improved, the function of flushing the main cavity through the auxiliary cavity is achieved, and the problem is solved that a tube hole of the main tube body is blocked.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a three-chamber gastric tube with a balloon. Background technique [0002] Gastric tubes are mainly used for abdominal gastrointestinal decompression, irrigation, nasal feeding, and drainage. At present, most common gastric tubes in the market are single-lumen. Gastrointestinal decompression, irrigation, nasal feeding, and drainage are all realized in one lumen, which is prone to lumen blockage and damage to the gastric wall, and cumbersome fixation on the patient's face is required. Moreover, as the gastric tube enters the patient's body, there is still the blind tube part of the gastric tube that penetrates into the patient's body and cannot be fixed. If the patient cannot maintain a stable posture or the patient's face is not fixed firmly, or the effect of reflux in the patient's stomach , causing the prolapse of the gastric tube itself, making the patient endure the pain of we...

Problems solved by technology

At present, most common gastric tubes in the market are single-lumen. Gastrointestinal decompression, irrigation, nasal feeding, and drainage are all realized in one lumen, which is prone to lumen blockage and damage to the gastric wall, and cumbersome fixation on the patient’s face is required.

Moreover, as the gastric tube enters the patient's body, there is still the blind tube part of the gastric tube that penetrates into the patient's body and cannot be fixed. If the patient cannot maintain a stable posture or the patient's face is not fixed firmly, or the effect of reflux in the patient's stomach , leading to the prolapse of the gastric tube itself, making the patient endure the pain of wearing the tube again, and even leading to greater medical accidents
