Definitions

  • the present invention relates to a hypodermic needle, of those used for the application of intramuscular or intravenous injections.
  • the object of the invention is to obtain a "painless" needle, that is to say that it does not produce pain or sensibly appreciable damage in the user when crossing its skin and other tissues that it must cross until it reaches the injection point.
  • hypodermic needles consist of a tubular body, of reduced diameter, topped by one end in a coupling head to the corresponding and complementary syringe, with its free end cut to a bevel, constituting a hollow and highly inserted insertion tip. sharp, so that when introduced into the body of the user produces an annular cut, with drag of a tiny cylinder of tissue, which is the cause of strong pain, specifically due to the tearing thereof.
  • hypodermic needle proposed by the invention fully solves this problem, completely eliminating pain due to "puncture", since it does not cause tissue tearing.
  • the needle that is recommended starting from a tubular body similar to that of a conventional hypodermic needle, focuses its characteristics on the fact that its free end is finished off, instead of a cutting bevel, in a Conical and solid tip, with a sharp vertex, which by its own configuration does not produce any cutting effect on the fabric, as previously mentioned, but a simple elastic deformation of the same around an imaginary axis, easily recovered after the extraction of the needle.
  • the said conical tip incorporates in its basal area, several lateral holes, of reduced dimensions, in direct communication with the tubular body, although and as such holes are evident they could also be located instead of the said tubular body, in the vicinity of the conical tip.
  • Figure 1 shows, according to a schematic representation in side elevation, a hypodermic needle made in accordance with the object of the present invention.
  • Figure 2. Shows an enlarged and sectioned detail of the conical tip that participates in the needle of the previous figure.
  • the needle that is recommended is constituted from a tubular body (1), of appropriate length and diameter, preferably of steel, topped by one of its ends in the classic head (2) coupling to the complementary syringe, as previously stated.
  • the said tubular body (1) incorporates at its end (3) opposite the head, a conical and solid tip (4), conveniently sharpened towards its vertex (5) and with a diameter in its base or internal limb coinciding with the outer diameter of the tubular body (1), as seen in Figure I a . - TO -
  • tubular body (1) and conical and solid tip (4) can incorporate a small annular neck (6) pluggable into the corresponding end of the tubular body (1) and attachable to the latter by any means, medium.
  • the conical tip (4) presents, emerging from its base (7) and directed towards its lateral surface (8), a plurality of tiny through holes (9), as observed especially in the detail of Figure 2, so that through these holes the liquid or pharmacological product in question leaves the needle towards the planned injection zone.
  • micro-holes (9) instead of being located in the conical tip (4), are located in the area of the tubular body (1) next to said tip.
  • the footprint left by the needle that is recommended is a simple point ( 11), as also shown in Figure 3, that is to say a considerably smaller and less damaging footprint, which occurs in the absence of pain.

Abstract

L'invention concerne une aiguille hypodermique se caractérisant en ce que l'extrémité du corps tubulaire opposé à la tête se termine par une pointe conique massive, dotée d'un sommet vif et pénétrant. Ladite pointe incorpore dans la zone proche de sa base une pluralité de petits orifices ouverts sur la surface latérale de celle-ci, pour le passage du liquide correspondant. La pointe conique massive incorpore de manière correspondante avec sa base un collier court pouvant être accouplé à l'extrémité correspondante du corps tubulaire et pouvant être fixé par un quelconque moyen à celui-ci, de manière que le diamètre de la base de la pointe conique corresponde au diamètre externe du corps tubulaire, et une continuité est établie entre l'intérieur dudit corps tubulaire et l'extérieur de la pointe conique.
