Definitions

  • the present invention relates to medical instruments, and more especially to the area of syringes for subcutaneous injections, which are designed in suc a way as to perform these injections using a retractable needle operated by means housed inside the syringe, the needle being contained inside an independent housing which is screwed onto the front end of the said syringe.
  • the needles are usually housed in a box, which may be described as a magazine, and, after having been used, are then placed unordered either in the box itself or in other spaces, and it is not always easy for the patient, who in most cases injects himself, to have a clear and complete picture as to the number of doses injected in a certain period of time, the number of needles and doses used, and the number of needles still available for use.
  • This monitoring must be done with the utmost accuracy, to avoid any uncertainty as to the dosage administered or identifying doses yet to be administered.
  • the inventor of the present invention has devised a set composed of a syringe and a magazine for the needles, the ease of handling and use of which, combined with a remarkable functionality of the whole, makes the monitoring described above extremely easy to carry out and in a certain sense "automatic".
  • an innovative magazine contains several retractable needles lined up coaxially inside it, with the first usable needle projecting out halfway.
  • the syringe forming part of the set is then designed in such a way as to be able to extract the said needle to be used by a quick, simple operation of axial engagement, and to be able to "unload" the same needle, after it has been used, by inserting it into the other end of the said magazine from that from which it had been projecting before use.
  • suitable locking and immobilizing means applied to or formed on the outer surface of the housing of each needle and on the inside of the front end of the syringe, plus a sliding distance piece inside the magazine, make the operation described above extremely simple and easy, obviating any possible mistake by the person handling the set.
  • the said magazine By making the said magazine of a transparent material, and applying progressive numbering to its outer surface, with the numbers spaced apart by the length of one housing containing a needle, it is possible to see clearly and immediately how many needles (and therefore how many doses) have been used and how many are still unused.
  • the construction of the abovementioned locking means more or less compels a user to reinsert a used needle, as noted earlier, into the said magazine in order to be able to get it out of the syringe. This prevents possible mistakes, distractions and/or forgetfulness.
  • a set 101 comprises a pen-type syringe 1, in the front end of which there fits, as illustrated, a cylindrical housing 4 containing in its interior a retractable needle 2 with associated elastic return means 22.
  • the above entioned cylindrical housing 4 differs from those of known type in having no screw thread, and in having on its outer surface a first circumferential groove and a second circumferential groove, indicated by reference numbers 5 and 12 respectively.
  • first groove is that which, when the housing 4 is inserted into the said syringe 1, is inside the front end le of the syringe, as indicated in the drawing.
  • locking means capable of reversibly securing the needle 2 to the syringe 1, which in this case take the form of at least one, but preferably two flexible elements 8, as depicted, terminating in an end with a part 8c shaped so as to fit snugly into the said first groove 5, which is basically semicircular in cross section.
  • Inserting the housing 4 axially into the syringe 1 causes the two flexible elements 8 to engage in the said first groove 5 in a bayonet-type coupling. Since the parts involved in the engagement are semicircular in shape, the engagement is reversible, because when the housing 4 is pulled it can still be extracted from the syringe 1 due to the flexibility of the said first flexible elements 8, which allows relative axial sliding movement between the parts. To prevent the housing 4 coming out of the syringe 1 accidentally while an injection is being carried out, the inventor has provided means inside the syringe 1 to make the above-described engagement temporarily irreversible for the whole of the duration of the injection.
  • the housing 4 also includes a second groove 12, which is outside of the syringe 1 when the housing 4 is inserted in the syringe, and this second groove 12 is used, as will be explained later, to remove the housing 4 from the syringe 1 and insert it into the magazine 3 forming part of the injection set 101.
  • this magazine 3 On its inside, at least one, but preferably two second flexible elements 11, conceptually similar to the first flexible elements described above. These also end in a part lie so shaped as to engage with the said second groove 12.
  • This last groove unlike the first, is not shaped like a semicircle but rather as a right-angled triangle (see also Figure 7) with one short side A vertical, the other short side B horizontal and level with the outer surface of the housing 4, and the vertex D, formed by the horizontal short side B and the hypotenuse I, oriented towards the first groove 5.
  • the syringe 1 After inserting the housing 4 in the magazine 3 far enough for engagement to occur (of bayonet type) of the second flexible elements 11 in the second groove 12, the syringe 1 is simply pulled back (arrow B) and the housing 4 is pulled out of the syringe 1 and held inside the magazine 3.
  • a magazine 3 of a set 101 also contains a sliding distance piece 13 of cylindrical shape, its length equal to one half of the length T of a housing 4.
  • the magazine 3 has a length L equal to n times the length T of one housing 4, as in Figure 4, and the said distance piece 13 is placed inside it, the housing 4 next due to be used can always be kept projecting halfway out of the magazine 3, to enable it to be collected for use by engaging a syringe 1 upon it as shown in Figure 3.
  • the said distance piece 13 thus acts as a separator between used needle housings and unused needle housings, as shown for example in Figure 5.
  • the magazine is made of a transparent material, a mere glance through this material will suffice to show precisely how many needles have been used and how many are left. If however the magazine and the housings contained inside it have colours and outlines that are not clearly distinguishable from each other it is still possible to refer to the position of the distance piece 13, which can be produced in a more vivid colour to enable its outline to be distinguished clearly.
  • the inventor also proposes affixing, to the outside of the magazine 3, progressive numbering 14 ( Figure 1) composed of successive numbers aligned parallel to the longitudinal axis of the magazine 3, and making a hole 13f, or marking a circle, on the said distance piece 13 in such a way that, as the latter advances along the magazine, the hole or circle appears behind one of the numbers of the said progressive numbering 14. In this way, depending on the direction in which the successive numbers are aligned in increasing or decreasing order, the number of used needles or of unused needles can be immediately read off.
  • the distance piece 13 in order for the said hole 13f or circle thereof to be able to exactly circumscribe one of the numbers 14, it must not be able to rotate about its own longitudinal axis.
  • the inventor suggests forming on its outer surface two (or more) reliefs 15 extending linearly parallel to the longitudinal axis and engaging them in corresponding slots 16 of complementary shape formed on the inside surface of the magazine 3.
  • the said slots 16 may advantageously be interrupted at one of their ends in the vicinity of one of the open ends of the magazine 3 so that the distance piece 13 cannot come out at their end.
