Definitions

  • the present invention relates to medical appliances, and more particularly to the area of retractable needles that are housed, together with an elastic pusher, in a usually cylindrical housing, which may be independent or may be part of a pen-type syringe for subcutaneous injections or for making punctures for the purpose of examining the blood.
  • retractable needles avoids the risk of inadvertent needle sticks and the associated risks, and reduces the emotional tension of the person receiving the injection, which would be aggravated by the sight of a fixed needle.
  • retractable needles and the associated syringes are often used directly by patients who have to undergo long-term or indefinite therapies, such as insulin therapy.
  • the inventor of the present invention has devised a cylindrical housing for a retractable needle, in which there is applied to its surface that it is to be pressed against the skin a layer of absorbent material soaked with disinfectant and covered by a removable impermeable membrane to protect it over time.
  • the said disinfectant-soaked layer must necessarily be pressed against the skin in the area where the needle is to be inserted. This guarantees that this area is disinfected, more especially if facilitated and enhanced by local rubbing by the patient.
  • the point of the local rubbing is also to disinfect that area of the skin which is immediately opposite the centre of the said disinfectant-containing layer, in cases in which there is a hole in this layer for the needle to pass through.
  • the subject of the present invention is therefore a housing as described in the appended Claim 1.
  • Figure 1 a longitudinal section through a housing according to the invention in the case in which it coincides with the end part of a pen-type syringe for subcutaneous injections; in Figure 2 a longitudinal section through another housing according to the invention in the case in which it is an independent part housed in the end part of a syringe capable of containing it in the interior of its end part; and - in Figure 3 an end view of that part of the housing seen in Fig. 2 which is adjacent to the interior of a syringe, fitted with a membrane with predefined breakage lines.
  • FIG 1 shows a cylindrically shaped housing 1 consisting of the end part 3t of a "pen” type syringe 3 for subcutaneous injections, which contains in its interior a retractable needle 2 with the associated elastic return means 22 (a simple spring in the case depicted).
  • the abovementioned housing ends in an end wall 4 with a central hole 5 for the needle 2 to pass through, to the outer face 4e of which there is applied, by adhesives or other methods of known type, a layer 7 of absorbent material, preferably of spongy type to give it a certain softness, and impregnated with one of the numerous types of disinfectant in the fluid or liquid state.
  • This layer 7 is completely covered by an impermeable membrane 6 cut for example from aluminium foil, and attached to the housing 1 by adhesives, heat-welding or other such system. Projecting from this membrane 6 is a tab 6e that can be used to pull the said membrane 6 off when the syringe 3 is to be used to make an injection by pressing onto the retractable needle 2 a cartridge 10 containing the liquid 12 to be injected.
  • the said layer 7 preferably itself has a hole 7f for the retractable needle 2 to pass through.
  • the end wall 4 and consequently the abovementioned layer 7 is placed against the area of the skin where the needle is to penetrate, thus achieving the result that the mere contact, especially if accompanied by slight local rubbing, results in disinfection of the said area such as to reduce the risk of infection and the harmful consequences which can be occasioned thereby.
  • FIG. 2 Another illustrative embodiment of a housing 11 according to the invention, with identical aims and functions, is drawn in Figure 2.
  • the housing 11 of the invention containing in its interior a retractable needle 2 with its elastic return means 22, forms an independent part and is inserted in the open end part 13t of a pen-type syringe 13.
  • This system was devised by the same inventor, and is disclosed in another Swiss patent application) .
  • the cylindrical housing 11 has an end wall 4 containing a hole 5, to the outer face 4e of which there is applied, in exactly the same way as described with respect to the previous example, a layer 7 impregnated with disinfectant and covered by a membrane 7, which seals it to maintain its effectiveness over time, and this membrane can be pulled off using a tab 7e projecting from it.
  • This additional membrane 26 comprises (as can be seen in Fig. 3) a number of predefined breakage lines Li so that it can be torn by the cartridge 10 containing the liquid 12 to be injected when the cartridge is pressed against it in the course of an injection.

Abstract

L'invention concerne un boîtier (1, 11) capable de renfermer, à l'intérieur, une aiguille rétractable destinée à une seringue de type 'stylo' (3, 13) permettant d'effectuer des injections sous-cutanées ou des ponctions et présentant une paroi terminale (4) comprenant un trou central (5) permettant à l'aiguille (2) de passer à travers celui-ci. Une couche (7) de matériau absorbant imprégné de désinfectant et totalement recouverte d'une membrane imperméable amovible (6, 16) fixée de manière sûre sur le boîtier cylindrique (1, 11) est appliquée sur la surface externe (4e) de la paroi terminale (1, 11).
