Disposable pneumo-barium generator

Abstract

The invention relates to a one-time air barium generator, and is characterized in that the air barium generator comprises an air barium mixing chamber (3) on which a barium intake duct (1), an air intake duct (2), and a sucking duct (4) are arranged, wherein the barium intake duct (1) and the air intake duct (2) are arranged on the same side of the air barium mixing chamber (3), the sucking duct (4) is arranged on the other side of the air barium mixing chamber (3), and the barium intake duct (1) and the air intake duct (2) are respectively sheathed with a first flow regulating valve (5) and a second flow regulating valve (6). The invention is simple in structure and convenient to use, the success rate of angiography is high in barium meal examination, compared with oral aerogenic agents, the invention is easily accepted by patients, the air quantity is adjustable, and the generating of air bubbles is avoided. The one-time air barium generator is a quite ideal medical apparatus and has excellent popularization using value.

Description

technical field [0001] The invention relates to a medical device, in particular to a disposable gas barium generator which can be used for medically performing gas barium double-contrast contrast X-ray examination on esophagus and stomach. Background technique [0002] At present, gas-barium double-contrast X-ray examination of esophagus and stomach basically adopts the method of oral gas-generating agent to generate the necessary amount of gas in the process of contrast. All patients who have undergone barium meal examination know that barium meal is delicious, but the gas producing agent that must be taken before barium meal, whether it is tablet or powder, is really difficult to swallow. A large amount of gas gives people a feeling of fullness. Once the patient does not pay attention, a few breaths will cause insufficient gas, and it will be difficult to form a barium image, making diagnosis difficult. Moreover, in practical applications, the gas generating agent is pron...

Problems solved by technology

All patients who have undergone barium meal examination know that barium meal is delicious, but the gas producing agent that must be taken before barium meal, whether it is tablet or powder, is really difficult to swallow. A large amount of gas gives people a feeling of fullness. Once the patient does not pay attention, a few breaths will result in insufficient gas, and it will be difficult to form a barium image, making diagnosis difficult.

Moreover, in practical applications, the gas generating agent is prone to produce many bubbles that cannot dissipate, resulting in a decrease in gas production and artifacts in the image, resulting in a decrease in inspection quality or unsuccessful inspection
