Description

Orogastric tubes that extract and store stomach contents

technical field

The patent of the present invention relates to a new type of oral gastric tube, to be precise, a new type of gastric tube that can extract and store gastric contents through the mouth.

Background technique

The existing traditional oral gastric tube is usually a single-structure tube, that is, there is no one-way valve switch and gastric content storage device. It does not have a separate storage device for gastric contents after the catheter is placed, which will have a certain impact on the retention of gastric contents and the next biochemical detection, and no balloon is fixed in the stomach. If the patient resists too much, it is easy to cause gastric tube. Fall out, affecting the patient's eating. Especially when the patient has symptoms such as disturbance of consciousness due to abnormal gastrointestinal function, such as septic shock caused by strangulated intestinal obstruction, after the catheter is placed, the patient cannot fully understand the contents of the patient's stomach because he cannot express his own situation clearly. In this case, there is no suitable storage device for extracting gastric contents through the existing traditional oral gastric tube, and part of the gastric contents will flow back into the stomach, which affects the further treatment of the patient. The existing traditional oral gastric tube has no fixed device. If the gag reflex of the patient is too strong, the gastric tube will be spit out, which affects the next feeding and the detection of gastric contents.

To sum up, the existing traditional oral gastric tube intubation has a single form, and there is no separate pipeline to suction gastric contents, no gastric contents storage device, no one-way valve and three-way switch device, and no gastric contents. The retention of the sample and the next step of biochemical testing will have a certain impact; when re-injecting food into the gastric tube, the injection end needs to be reversed, which will easily cause the gastric tube to stick and reduce the service life of the gastric tube. In addition, the gastric tube is easy to fall out without a fixing device, which affects the patient's eating and delays the patient's treatment process, and has obvious defects.

A one-way valve between the three-way switch and allowing the gastric juice in the internal pipeline to flow into the gastric content storage bag, and a clamp for closing the third pipeline after the scale tube is fixed on the third pipeline.

Further, the balloon is made of medical rubber material.

Further, the position of the balloon is defined as "upper", the position of the solid guide head is defined as "lower", and the opening is in the shape of a small upper and a lower large.

Further, the shape of the through opening is but not limited to one of a gourd shape, a convex shape, and a trapezoid shape.

Further, the shape of the stomach contents storage bag is but not limited to one of a rectangular parallelepiped and a cylinder.

Further, ports of the first pipeline and the second pipeline are provided with port covers.

The beneficial effect of the invention is that the stomach contents can be effectively extracted and stored without contaminating the injection food tube, and the contents can be extracted for effective biochemical detection, and the use of the three-way switch can make the two tubes perform their respective duties , the injected liquid food and the extracted gastric contents do not contaminate each other. It is closed after use, and there is no need to repeatedly reverse the gastric tube, which increases the service life of the gastric tube. The existence of the air and water injection balloon can effectively fix the pipeline and prevent the pipeline from falling out of the mouth due to excessive movement of the patient. The gourd-shaped opening at the end of the scale tube can effectively prevent the food particles from being too large and blocking the gastric tube.
