Description

Technical Field

[0001] The present invention relates to the technical field of drainage devices, in particular to a drainage device for detecting gastric residual volume. Background Art

[0002] A gastric tube is used in special circumstances to help patients who cannot swallow deliver necessary water and food. The gastric tube is generally made of polyurethane or silicone and has different specifications of thickness, length and length. The gastric tube is divided into orogastric tube and nasogastric tube. Medical staff insert it into the patient's mouth or nose until its end is located in the stomach.

[0003] For patients who cannot eat orally and need to have a gastric tube for a long time, such as patients with stroke, hemiplegia, tracheoesophageal fistula, etc., since the patients cannot eat orally on their own, they need to be assisted by a gastric tube. Before the patient eats, the nurse needs to first check the residual volume in the patient's stomach to avoid the residual volume in the stomach exceeding a certain limit, causing the patient to vomit while eating, or even causing the patient to aspirate into the lungs. If the intragastric pressure cannot be monitored in real time when injecting liquid into the stomach, treatment may be delayed due to failure to detect problems such as gastric retention.

[0004] Common gastric tubes are generally single-channel structures that can only be used to deliver nutrient solution or extract gastric juice, and their functions and uses are relatively limited. In current operations, when it is necessary to measure the intragastric pressure of a patient, a pressure measuring catheter needs to be inserted into the human stomach, which is not only difficult to operate, but also has many adverse effects on the patient. Currently, there is a lack of devices that can monitor both the amount of gastric residual material and the intragastric air pressure. Summary of the invention
