Definitions

  • the usual means employed for this purpose is a syringe nozzle which has been held in position against the fistula. either by hand or, whenever possible, with the aid of adhesive plaster or some other type of binding.
  • Another object of this invention is to provide an instrument for such purpose where the instrument can be maintained in position without any help of human hands, and no assistant person can be exposed to injuries from the X-rays.
  • Still a further object of the invention is to provide an instrument for such purpose where the instrument per se is built up to leave a clear passage for the X-rays directly towards the fistula without any harmful surface angles being present in the instrument.
  • the invention is substantially characterized by an instrument in the shape of a disc, the skin-facing side of which is provided with an annular groove and .a central column with a bore serving as the exit end of a fluid carrying duct, and also with a joint fitting adapted for connection to a syringe or the like, in addition to which the mouth of an air evacuation duct is provided in the annular groove, the opposite end of the duct being adapted for connection to a vacuum pump or some other suction device.
  • FIG. 1 is a cross section of the device on an enlarged scale
  • FIG. 2 is a plan view of the device
  • FIG. 3 is a cross section of a portion of a somewhat modified design.
  • the device consists substantially of a disc with one side 2 of the disc 1 constituting the side to be positioned against a fis-tula or boil 3, including portion 4 of the skin, opposite other side 5 faces outwards.
  • the side 2 is provided with an annular groove 6, surrounding a central column 7, having a centrally disposed exit or outlet 8 of a fluid carrying duct 9, which at the edge of the disc is provided with a union fitting 10 for the connection to a syringe or other injection device (not shown).
  • outlet aperture 11 of an additional duct 12 which serves as a channel for the evacuation of air from the annular groove, and the opposite end of the air evacuation duct 12 is provided with a union 1 3 preferably also disposed at the edge of the disc for attachment in known manner to a vacuum pump of other air evacuation device.
  • the annular groove 6 has substantially the form of an elongated ellipse, with one edge coinciding with the groove aperture in the side 2 of the disc which is shown as plane in the embodiment according to FIGS. 1 and 2.
  • the side of the central column 7 will appear as a curve-shaped concave surface which, in cross section is limited by two sub- 3,207,150 Patented Sept. 21, 1965 ice stantially semicircular arches, and the same groove-forming shape also prevails at the outer circumference of the groove.
  • This curve-form near the central column is of particular significance, as will be evident from the further description below.
  • the disc Since it is intended to take X-ray records with the disc in position over the fistula, the disc should preferably be transparent. Apart from taking this matter into consideration, the disc can be made of any kind of material, although plastic material is preferable. For the sake of facilitating X-ray photography, the outer as well as the inner side of the disc has been made substantially plane, thus enabling X-ray pictures to be taken without distortion. Not even the fine bore ducts embedded in the disc will interfere with the clearness of the picture. This is the reason for the connection mean being disposed at the edge of the disc, thus avoiding shadowing objects on the plain surfaces of the disc.
  • the strainer plate may be concave in shape.
  • the disc When using the device, the disc is placed immediately over the fistula with the exit end 8 of the nozzle as far as possible directed towards the principal pus carrying duct of the fistula.
  • the air in the annular groove is then evacuated, causing the port-ion of the skin around the boil to be drawn into the groove 6 and forming a ringshaped blister, holding the disc in position.
  • the disc will be very securely retained in position against the skin around the outer edges of the annular groove.
  • the effect close to the central column is then particularly advantageous, since the epidermis covering the fist-ula will be tensioned and stretched, with the result that the pusduct outlet or outlets will be widened and thus easier to observe and also facilitate the injection of the contrastive fluid into the same.
  • the details of the device may be subject to variations.
  • the disc may thus have its sides executed in a shape differing from the plane design.
  • the range of application is not confined to fistulas only, and the device can be used for purposes of injection into other parts of the body. It can, for example, be used for injection of contrast fluids into the nipples of the mammary glands for X-ray examination in cases of suspected cancer.
  • a device for the injection of fluids such as contrasting fluids into fistulas for X-ray purposes comprising a disc having opposite parallel sides, at least one of said sides being planar, and a peripheral wall, the side opposite the planar side being the fistula facing side, the peripheral wall being of such dimensions as to accommodate a deep and broad groove defining an annular suction chamber open toward the fistul-a side, a thick central column defining a central annular wall for the suction chamber located within said chamber and extending from the top of the chamber and having a free end terminating in the plane of the fistula facing side and adapted to cover the fistula, the dimensions of the peripheral wall being such as :to accommodate a channel extending in parallelism to said planar side of the disc and having an inlet end adjacent the peripheral wall, a fitting for connecting said inlet end to a source of contrasting fluid, said central column having a duct communicating with said channel extending longitudinally of the column and provided with an outlet located at the free end of the
