Definitions

  • the invention relates to a needle magazine for storing, dispensing and collecting a number of needle assemblies.
  • Medical injection devices are used to deliver selected doses of medication to patients. Some medication, such as insulin is self-administered. The typical diabetes patient will require injections of insulin several times during the course of the day. In order to prevent infections it is recommended to use- a sterile needle assembly for each new injection. Needle assemblies are often delivered in a separate housing where such housing contains only one sterile needle assembly. Such a housing is shown in figure 1. The needle assembly and the housing together are hereafter referred to as a needle unit. Using a needle assembly of this kind requires the patient to open the housing and to fasten the needle assembly onto the injection device prior to each injection, as shown in figure 2. Usually the needle hub of the needle assem- bly is provided with an internal thread and force fitted into the housing.
  • a typical injection device is on the tip provided with an external thread, which fits in the internal thread of the needle hub.
  • the two elements In order to connect the needle assembly and the injection device the two elements must be rotated relatively to each other. In order to facilitate a better grip on the needle assembly, this is usually kept in the housing when mount- ing it on the injection device. After injection, the needle assembly is usually returned to the housing, and the complete needle unit is disposed of.
  • the storage of sterile needle units of this type and the final disposal of used needle units present a problem, since new sterile needle units are often carried loosely in purses or briefcases, and used needle units are often disposed of unsafely.
  • a needle magazine for storage and dispensing a plurality of needle units has been developed.
  • An example of such prior art magazine is shown in WO 00.54691 , and comprises a plurality of needle units stored on a needle unit holding plate.
  • the needle unit holding plate is provided with two opposite located grooves into which grooves the needle units slides.
  • the needle units are covered by the needle unit holding plate, and must be separated from the needle unit holding plate prior to being mounted on the injection device.
  • This needle magazine comprises of a needle storage case where the needle units are stored in a plurality of needle unit engaging holes each storing one needle unit.
  • the storage case is provided with a lid, which can slide to an open position in order to access the needle units.
  • the housings of the needle units are rotational locked to the needle storage case due to a series of anti-rotation ribs located on each housing, which ribs-interacts with a number of protruding ribs located on the side walls of the needle unit engaging holes.
  • the magazine according to the present invention is made from a number of individual modules, which are connected together to form a base member.
  • Each individual module is provided with at least one needle engaging hole for storing a needle unit and connecting means for connecting together a number of individual modules.
  • each patient can build a needle magazine, which facilitates that individual patients needs as far as the number of needle units is concerned.
  • each module is box shaped having an upper surface including the needle unit engaging holes, a bottom surface and four side surfaces located between the top and the bottom sur- face.
  • each module comprises a longitudinal channel provided between opposite side surfaces, and whereby a number of modules are connected together side by side, by mounting one peg in a longitudinal tunnel formed by the longitudinal aligned channels of neighboring modules.
  • the magazine can be connected by pushing or pulling a number of identical modules onto a peg, somewhat like pearls on a string.
  • each module comprises a longitudinal channel provided between opposite side surfaces, and whereby a number of modules are connected together side by side, by mounting a number of pins in the longitudinal tunnel formed by the longitudinal aligned channels of neighboring modules, it is ensured that a number of different pins can be utilized in connecting together the modules of a needle magazine according to the present invention.
  • the pins used to connect the modules to each other can either be loose pins as dis- closed in claim 4 and 5, or the pins can be moulded as an integrated part of each module as disclosed in claim 6
  • each module can be tilted such that the needle unit mounted in that spe- cific module has free space around the needle unit.
  • This has the advantage that the same needle magazine can accommodate a large variety of different injection devices including non-symmetrical injection devices having an abutment, which abuts the skin during injection, such as the Innovo® and the InnoLet® from Novo Nordisk.
  • each module can be provided with one or more raised portions on one of the side surfaces and similar depressions on the opposite side surface, such that a side surface carrying a raised portion will abut the side surface of the neighboring module having depressions when the needle magazine is connected. This will ensure that the modules are being properly indexed in relation to each other when the module in use is being tilted.
  • the depressions would typically be located 90 degrees apart from each other.
  • the base member is provided with a lid covering the needle unit engaging holes form above, and which lid preferably slides in a number of grooves provided on two of the side surfaces located opposite each other.
  • a lid covers it more hygienic to carry the needle magazine in a purse or a briefcase, and protects the barrier sheet from being damaged.
  • a lid sliding in a number of groves, a lid that tips or twist can be used.
  • each needle unit engaging hole is provided with at least one needle unit engaging element, such as ribs or depressions, into which a needle magazine engaging element, such as ribs or depressions, on said needle unit is located, it is ensured that each of said needle units are non-rotatably stored in the needle unit engaging hole.

Abstract

L'invention concerne un magasin à aiguilles permettant de stocker et de distribuer sélectivement plusieurs assemblages d'aiguilles adaptés à un système d'injection d'insuline. Ce magasin à aiguilles est doté d'un certain nombre de modules en forme de boîtes, placés adjacents les uns aux autres et connectés ensemble côte à côte. Les modules en forme de boîtes sont pourvus d'une broche sur une surface latérale, alors que le côté opposé est doté d'un orifice de réception de cette broche dans lequel la broche du module (en forme de boîte) adjacent vient se fixer. Ainsi, un utilisateur seul peut construire un magasin à aiguilles, ce qui facilite les besoins de l'utilisateur seul par rapport au nombre d'unités d'aiguilles contenues dans le magasin à aiguilles.
