Definitions

  • the invention relates to an injection cannula in the form of a metal tube according to the preamble of claim 1.
  • the infective cannula can be used in practical medicine, especially for intramuscular injections of drugs.
  • injection cannulas consisting of a metal tube are used for the intramuscular injection of drugs into the human body.
  • one end of the metal tube is sharply molded, ie cut off obliquely.
  • a header is formed to connect to a syringe or to a flexible tube.
  • a patent search shows various training of commercial injection cannulas, which differ in their design and functionality. The closest approach to the invention is described in patent RU 2380121 C1 "Injection cannula and method for its use in subtle injections.” This known injection cannula prevents post-injection effusions with reduced blood coagulability by accelerating the occlusion of damaged vessels.
  • the metal tube is provided at a distance of 0.5 to 2.0 mm from the beveled end face with a number of identically extending notches.
  • the notches contribute to a uniform diffusion of the drug in the core of muscle tissues and in narrow interlayers of the loose fibrous connective tissue endomysium. This avoids the formation of large drug depots and, accordingly, the formation of infiltrates.
  • the notches may be perpendicular to the longitudinal axis of the metal tube and extend only over part of the circumference of the metal tube.
  • the notches may also extend parallel to the chamfered end face of the metal tube and extend only over part of the circumference of the metal tube.
  • the notches can also run parallel to the longitudinal axis of the metal tube and extend evenly distributed over the circumference of the metal tube.
  • a further embodiment of the injection cannula provides that the notches (18) at the end (11) of the metal tube (10) in parallel to the longitudinal axis (17) of the metal tube (10) extending rows of circular notches (18) are arranged over the circumference of the metal tube (10) in evenly spaced rows in the metal tube (10) are introduced (Fig. 4).
  • the outer diameter of the metal tube is 0.4 to 2.0 mm, the length of the metal tube 40 to 150 mm and the angle (ß) of the beveled end face 15 to 45 °.
  • the inner diameter of the header is 2.75 or 4 mm and is thus adapted to the outer diameter of various commercially available syringes or flexible tubes.
  • Fig. 1 is an injection cannula with perpendicular to the longitudinal axis of the metal tube notch
  • Fig. 3 is an injection cannula with parallel to the longitudinal axis of the metal tube extending notches and
  • Fig. 4 is an injection cannula with parallel to the longitudinal axis of the metal tube extending rows of round notches.
  • the structure of all injection cannulas has a metal tube 10 having an outer diameter of 0.4 to 2 mm, one end 11 of which is obliquely cut off and forms an end face 12 with the angle ⁇ of 15 to 45 °.
  • the metal tube 10 is 40 to 150 mm long and merges from the other end 13 into a header 20 for a commercial syringe or flexible tube.
  • the headpiece 20 may have an inside diameter of 2.75 mm or 4 mm and thus be adapted to the outside diameter of various commercially available syringes or flexible tubes.
  • the injection cannula of Fig. 1 carries at a distance of 0.5 to 2.0 mm to the end face 12, three notches 14, which are spaced and extend over a portion of the circumference of the metal tube 10.
  • the notches 14 are perpendicular to the longitudinal axis 17 of the metal tube 10 and repeat themselves diagonally on the metal tube 10th
  • the notches 15 run approximately parallel to the end face 12 of the end 11 of the metal tube 10 and likewise extend only over part of the circumference of the metal tube 10. These notches 15 can also repeat diagonally on the metal tube 10.
  • Fig. 3 shows an injection cannula, in which the notches 16 extend parallel to the longitudinal axis 17 of the metal tube 10, wherein these notches 16 in the longitudinal axis 17 about the same range of 0.5 to 2 mm as the three notches 14, 15 of Injection cannulas according to Fig. 1 and 2 extend.
  • the notches 16 are evenly distributed over the circumference of the metal tube 10.
  • the notches 18 may also be arranged in rows parallel to the longitudinal axis 17 of the metal tube 10 and may be formed as round notches 18, as shown in FIG. 4.
  • the row of notches 18 extends again at a distance of 0.5 to 2 mm to the end face 12 of the metal tube 10. Several rows may be evenly distributed over the circumference of the metal tube 10.

Abstract

L'invention concerne une canule d'injection sous forme d'un petit tube métallique dont une extrémité (11) est biseautée selon un angle (ß) et dont l'autre extrémité (13) est pourvue d'une tête (20) destinée à y raccorder une seringue ou un tube flexible. Afin d'empêcher toute infiltration intramusculaire lors d'injections intramusculaires dans les muscles fessiers, celle-ci provoquant souvent des douleurs et, au pire des cas, des inflammations et nécessitant des interventions chirurgicales, le petit tube métallique (10) selon l'invention présente un nombre d'encoches (14, 15, 16, 18) ayant la même orientation et se trouvant à une distance de 0,5 à 2 mm de l'extrémité (11) pourvue d'une face frontale biseautée (12).
