Abstract
The present invention relates to a gas-forming capsule for gastrointestinal double contrast radiography, belonging to a change of dosage form of gas-forming agent for X-ray gastrointestinal double contrast radiography diagnosis. Said capsule is made of gelatin, and can be disintegrated after 3 min. in endogastric acid environment, and can release the drugs contained in it. The drugs contained in the capsule are citric acid + sodium bicarbonate. After the capsule is disintegrated, the above-mentioned drugs are reacted, and CO2 gas is released.
Description
The present invention relates to a kind of 100% gas generating agent at gastric generation gas, especially effect is obvious when low-strain air-barium imaging.
At present, Chang Yong double contrast radiograph gas generating agent is two kinds in tablet and a powder; Aerogenesis sheet or gas producing powder be put in the oral cavity take after mixing it with water, produce gas, but in the process of taking because the dosage form factor makes gas producing powder about 30% aerogenesis in oral cavity and esophagus, even 100% in the oral cavity aerogenesis; Cause gastric gas very little, do not reach the purpose that flattens coat of the stomach, make the double contrast radiograph effect relatively poor, same, the aerogenesis sheet is general oral more than 20, not only contain more additive in it, produce pseudo-shadow at gastric, and Chang Yin makes moist, gas discharges in advance, in gastric gas production deficiency, influence the effect of double contrast radiograph.
The purpose of this invention is to provide a kind of gas generating agent, it not only can provide the gas of capacity at gastric, and taking convenience, and consumption is less.
The object of the present invention is achieved like this: make the capsule that can partly insert mutually with gelatin, medicated powder sodium bicarbonate and citric acid that aerogenesis is used are sealed in the capsule, just make its protection against the tide on the encapsulated plastic plate at ordinary times; In use can take the 4-6 grain as required.Can carry out simultaneously for loose dose with the intramuscular injection smooth muscle when taking, taking the back greatly can be at the generation gas of gastric 100% about 8-10 minute; The smooth muscle of intramuscular injection is simultaneously also had an effect for loose dose, and gelatin is made capsule disintegrate rapidly in 2 minutes in the gastric sour environment, discharges wherein sodium bicarbonate and citric acid; Meet waterishlogging and give birth to reaction, discharge 100% carbon dioxide at gastric, being created in gas can show area gastrica and stomach ditch with the barium agent under the loose situation of body of stomach smooth muscle.
Owing to adopted capsule formulation, make its taking convenience, people's pars oralis pharyngis is stimulated disappear, and can 100% produce gas at gastric, reach the purpose of double contrast radiograph.
Fig. 1, Fig. 2 and shown in Figure 3 in, be respectively separation graph, positive bitmap, perspective view; Capsule shells is the standard type capsule shells, several microns approximately of disgraces, and wherein a semidiameter is smaller than second half, and can be inserted in about 3mm mutually; Aerogenesis medicated powder is loaded in the capsule, and sealing.
Claims (3)
1, a kind of gastrointestinal remakes the shadow Aerogenic capsule again, and aerogenesis medicated powder is sealed in the capsule, it is characterized by: the gelatine capsule that two parts of gas generant composition in accordance pruinescence are inserted in seals, and in the process of swallowing, does not discharge gas in oral cavity and esophagus.
2, according to claim 1, it is characterized by: pack in the Aerogenic capsule sodium bicarbonate and citric acid, and sealing, capsule disintegrate in the gastric sour environment that gelatin is made is very fast, can 100% in 10 minutes discharge aerogenesis medicated powder in it, and produce gas, its equation is as follows:
3, according to claim 1, it is characterized by: the capsule sealing is loaded on moulding in the plate of damp proof insulation.
