Abstract

At present, most of the devices used by patients for gastric juice suction in clinical practice are disposable negative pressure drainage devices for gastric juice. Due to the material shape, the negative pressure is not enough, and the material breaks; when flushing is required, medical personnel are also required Manually separate the gastric juice negative pressure drainage device from the gastric tube, and then insert the syringe for cleaning, which brings inconvenience to doctors and patients in operation and use. The gastric juice flushing device of the present invention is composed of a negative pressure bottle, a pressurized bottle, a pressurized negative pressure device and a control switch. The present invention utilizes the molding on the negative pressure bottle, superimposes the pressurized bottle, and adopts the principle of the injection device to concentrate the ejected gas in the pressurized bottle, and at the same time, the negative pressure bottle is connected to the other end to generate negative pressure. Using a one-button switch group, the positive and negative pressure can be switched in a controlled manner without separating the gastric tube, and the dual functions of negative pressure drainage and flushing can be completed. One-button operation reduces the workload of medical staff, and the product is convenient and reliable.
