Definitions

  • This invention relates to a container for the simultaneous ad­ministration of barium sulphate suspension and air in the double con­trast X-ray examination of the upper digestive tract.
  • the invention concerns a container as mention­ed above, specifically designed for a routine X-ray study of the oesopha­gus, by which the simultaneous administration of the barium sulphate and air occurs without the use of mechanical insufflation means.
  • the object of this invention is to provide a container for administration of barium sulphate suspension which allows spontaneous deglutition of air, simultaneously as the barium suspension, whithout need of forced insufflation, and with no tubing for connection with air supply.
  • a glass-shaped container provided with an air-tight cover to which a substantially cy­lindrical internal air chamber is connected, a circular central portion of said cover constituting the top wall of said chamber, said cover being provided with an air inlet connecting said air chamber to the outside through the cover.
  • a mouth-piece projects from the cover, having an elliptical cross-section, being tapered towards the end opposite to the cover, and being divided into two parallel ducts: the first one, of a larger section,communicating with the interior of the container, for the barium suspension flow, and the second one, communicating with the air chamber, for the air flow.
  • Said first duct for the barium suspension flow is located in the lower portion of the mouth-piece, that is on the side that comes into contact with the lower lip during the administration.
  • the barium suspension comes to the mouth flowing throug the remaining space in the lower part of the mouth-piece, being the size ra­tios of the two flow orifices - for air and barium - fixed to such a value that the amount of barium suspension reaching the mouth is the minimum one sufficient for a normal deglutition.
  • This expedient allows longer times of examination of the oeso­phagus, as it causes a greater amount of air to enter at each degluti­tion of barium sulphate suspension.
  • the air chamber built under the cover helps in raising the amount of air that can be swallowed at each deglutition of barium, since it somehow slows down the flow of the barium suspension out of the container, towards the outlet to the mouth-piece.
  • said chamber constitutes an obstacle that projects towards the inside of the container, and increases the friction surface in contact with the barium suspension, thus limiting its flow velocity, owing to its viscosity.
  • a hollow is provided in the lower part of the air chamber, in the periph­eral zone facing the outlet to the mouth-piece.
  • a transversal rib is placed externally around the mouth-piece, at a short distance from the orifice, in order to define the point where the lips must be placed while drinking from the container.
  • the central circular portion of cover forming the upper wall of the air chamber is missing, so that a closed chamber for the air is no more present, and the cover shows a cylindrical cavity, open towards the outside.
  • the cylindrical cavity is open towards the outside, and forms a projecting part towards the interior of the container, in the same way as the air chamber of the previous embodiment does. Consequently, the above-mentioned advantage of slowing down the barium suspension flow rate towards the mouth-piece is maintained, and, at the same time, a notable economy of production is obtained, since the cover can be manu­factured by means of only one mold.
  • the simulta­neous administration of barium and air occurs without difficulty and the oesophagus can be in all cases examined by the double contrast technique. Moreover, in many cases the air insufflated is also suffi­cient for the double contrast study of the stomach and duodenum.
  • FIG 1 there is shown a container 1 having a truncated­conical form provided with a cover 2.
  • the cover 2 shows, on the internal part, the air chamber 3 which is in communication with the outside by the air inlet tube 4 and with the delivering orifice 5 through the duct 6 in the mouth-piece 7.
  • the air chamber 3 has a substantially cylindric form, with a hollow 8 made on the side turned towards the mouth-piece 7 which serves to facilitate the barium suspension flow.
  • the mouth-piece 7 has an elliptic cross section and the air duct 6, or semilunar form, is placed in the upper part of the mouth-piece 7, turned towards the pal­ate. The remaining part of the elliptic section of the mouth-piece 7 is occupied by the duct 9 for the barium sulphate suspension. If the two above-mentioned cross sections are accurately proportioned, an optimal ratio between the barium flow rate and the quantity of air swallowed together with it will be obtained. This technique allows to perform the best oesophagus X-ray examination with the double contrast method. At present a preferred size for the two air and barium sections 6 and 9 is, for example, 2 mm for the first one and 8 mm for the se­cond one.
  • the air chamber 3 inside the container 1 increases the contact surface with the barium suspen­sion when the container 1 is lifted for the deglutition, thus increasing the friction resistances to the flow of the viscous suspension, so as to reduce the barium administration velocity.
  • Figure 1 also shows the rib 10 for positioning the patient's mouth.
  • figures 3 and 4 corresponds exactly to the one of figures 1 and 2 (and the same numerals indicate corresponding elements), except for the fact that the central circular portion of the cover is missing, so that the cavity 3 is completely open towards the outside.
  • the dotted line shows the missing part of the cover and the missing inlet tube 4, for comparison with the previous embodiment.
