2. inserting the gastric tube into a human body, and detecting liquid in the balloon by using an ultrasonic detection device in the insertion process, namely guiding by utilizing ultrasonic in the insertion process of the gastric tube, and guiding by X development;
3. after the end of the stomach tube reaches the target position, nutrient substances or other liquid are injected into the main channel 2, and the substances of the main channel 2 flow into the human body through the side through holes 3 on the catheter body 1.
That is, in normal use of the gastric tube, the two sub-balloons are in an inflated state and seal the opening of the second end of the main passageway.
When large particles or high-concentration nutrient substances block the main channel, the expansion medium is fully or partially led out, so that the two sub-balloons are in a non-expansion state or a non-full expansion state, and the opening of the second end of the main channel is opened, so that the main channel is conveniently flushed and cleaned, and the problem that the gastric tube is difficult to clean after being blocked is solved.
When high-strength negative pressure drainage is needed, the two sub-balloons are in a non-expanded state or a non-fully expanded state, so that an opening at the second end of the main channel is opened, and the drainage efficiency is increased.
When the substance is required to be delivered from the second end of the main channel into the human body, the opening of the second end of the main channel can be opened by controlling the two sub-balloons, and the expansion degree of the sub-balloons can be controlled by controlling the amount of the expansion medium in the sub-balloons, so that the opening of the second end of the main channel is further controlled.
