Embodiment Construction

[0019] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] Such as Figure 1~4 As shown, this gastric tube 1 with the device for preventing gastric content reflux proposed by the present invention is divided into three parts: head, middle part and tail, and the total length is 100-150 cm. At 25cm from the end, start to mark the length scale value of 25cm, and then mark the cumulative length value at intervals of 5cm in the direction of the head of the gastric tube until 90cm. The gastric tube is made of silicone material that meets medical hygiene standards. The central main channel 4 runs through the entire gastric tube. The head is the part exposed outside the human body, the middle part is the part from the nasal cavity to the esophagus, and the tail is extended into the stomach. part.

[0021] There is a main chamber 7 connected to the main channel 4 at the head of the gastric tube, and t...

Abstract

The invention relates to a stomach tube with a device for preventing the backflow of gastric content, which is divided into a head part, a middle part and a tail part. The stomach tube is characterized in that a main channel for infusing nutrient solutions, water and medicaments is penetrated through the head part, middle part and tail part in the stomach tube; the head part is provided with two parallel cavities; the upper end opening of the main channel is communicated with the head part of the stomach tube and is open at a main cavity of the two parallel cavities; a subsidiary cavity for infusing gas is further arranged in the two parallel cavities at the head part of the stomach tube; the subsidiary cavity is provided with a charging connector having a locking device; the subsidiary cavity is communicated with an umbrella-shaped backflow-preventing device around the outer wall at the middle lower part of the stomach tube through a gas bag channel positioned in the wall of the stomach tube; and the tail part of the stomach tube is provided with the lower end opening of the main channel. The invention can effectively solve the serious clinical problem such as suffocation, inhalation pneumonia and the like caused by mistakenly inhaling gastric content backflow into the trachea.

Description

technical field [0001] The invention relates to a gastric tube with a device for preventing the reflux of gastric content. Background technique [0002] With the development of social economy, people's medical needs have increased significantly. Clinically, patients who are unable to eat independently include many diseases such as coma caused by cerebrovascular accident, dysphagia, choking and coughing when drinking water, and patients with senile depletion and so on. In clinical treatment, the indwelling gastric tube is used to inject nutrients such as nutrient solution as an important method to maintain the body's basic nutrition, which is used to improve the nutritional status of patients and promote disease recovery. The gastric tube can be used as a drug delivery channel to inject drugs for treatment. In addition, there are a large number of patients undergoing gastrointestinal surgery, as well as patients with intestinal obstruction, who also need to indwell a gastric...
