Definitions

  • the invention relates to an ampoule opener.
  • An ampoule is a small sealed vial, which is used to contain and preserve liquid or solid products, usually
  • Ampoules are generally made of glass, though plastic ampoules also exist. They are hermetically sealed and comprise a body and a tip, connected by a narrowed neck. Ampoules are opened correctly by snapping at the neck, at a weakened line, in a clean break with no splinters of glass.
  • Ampoules can be opened by using just the hands, but in order to reduce the risk of injury to the hands, different mechanical ampoule openers have been devised, especially for use in the medical sector.
  • EP 1749801 Al discloses an ampoule opener apparatus of relatively complex construction. This apparatus comprises a suction device for removing snapped off ampoule tips, liquid and potential splinters of glass.
  • Another object is to provide an ampoule opener, which reduces risk of spillage of content of ampoules.
  • a further object is to provide an ampoule opener, which can be operated quickly and safely, even in stressful environments with limited space, such as in an ambulance.
  • the ampoule opener comprises a lid to a container or a container and means to snap off a tip of an ampoule, said means being arranged on the side of the lid or container and comprising an insertion tube that protrudes from the side in a downward direction at a sharp angle relative to the side and which has a flexible opening at its outwardly facing end.
  • flexible opening is meant that the opening is somewhat resilient allowing a slight increase in diameter of the opening. The flexibility is such that a grown up person can press the tip of the ampoule having a tip portion with slightly bigger diameter through the opening using finger pressure only.
  • the angled insertion tube ensures that the ampoule tip can be snapped off with limited or even no risk of content spillage from the ampoule.
  • the flexible opening in the insertion tube's outward-facing end ensures that the ampoule is held at in the correct position by the neck portion, so the tip of the ampoule is broken off in the correct way with limited risk of forming splinters of glass. The user may even insert the tip of the ampoule and leave the ampoule hanging by the neck portion if interrupted.
  • Another advantage of the flexible opening is that the user is provided a tactile feedback that the tip of the ampoule is correctly arranged in the ampoule opener enabling fast and reliable operation of the ampoule opener. Yet another advantage of the flexible opening is that the snapped off ampoule tip cannot fall out of the insertion tube.
  • the dimensions of the flexible opening in the insertion tube's outwardly facing end are constructed such that the tip of the ampoule can be pushed through the opening and be retained by the opening after being snapped off. A snapped off ampoule tip remains in the insertion tube until the insertion of the next ampoule tip. This one will push the first ampoule tip into a container, under the lid, as claimed by the invention, or into the actual container, as claimed by the invention.
  • the lid or container is made entirely or partially of plastic.
  • Plastic is a low cost and widely used material providing easy and cheap manufacturing.
  • Other materials could be used, such as metal, e.g. aluminium of stainless steel if robustness is of high importance or to facilitate cleaning with high temperature liquid or certain cleaning agents.
  • the insertion tube is angled relative to the side of the lid or container at angle of approximately 30-45 degrees, preferably at about 30 degrees. Other angles are possible, but these are well suited to avoid spillage, especially in the lower end of the range. An angle of up to 45 degrees or even above on the other hand makes it easier to see the opening for the user, whereby operation may be easier and more reliable.
  • the insertion tube is angled relative to vertical at an angle of approximately 30-45 degrees, preferably at about 30 degrees. Other angles are possible, but these are well suited to avoid spillage, especially in the lower end of the range. An angle of up to 45 degrees or even above on the other hand makes it easier to see the opening for the user, whereby operation may be easier and more reliable.
  • the side of the lid or container may be curved, such as forming a sphere or semi-sphere, or the side may in other ways deviate from a plane having a substantially vertical extension.
  • multiple insertion tubes are arranged on the lid or " container, allowing several users to operate the ampoule opener simultaneously. This is in particular an advantage when several users are working in an area with limited space, such as in an ambulance.
  • the flexible opening in the outwardly facing end of the insertion tube consist of an elastic ring, for example made of rubber.
  • the flexible opening can also be formed as an integral part of the insertion tube. This can be achieved by forming cuts or slits in the wall surrounding the opening thereby providing increased flexibility of the reveal of the opening.
  • the lid or container comprises, as claimed by the invention, an opening for inserting used hypodermic needles and/or ampoule bodies.
  • Used ampoule tips, used ampoule bodies and/or used hypodermic needles can by this means be collected in a single container and sent for destruction.
  • the ampoule opener can be operated with one hand, especially when it is fixed to an object such as wall, for example. It is therefore preferable that the ampoule opener comprises means for fixation, especially reversible fixation, so that the used ampoule tips, used ampoule bodies and/or used hypodermic needles can be easily emptied from the ampoule opener.
  • the means for fixation may be a bracket comprising a male and female part, the male part being connected to the ampoule opener and the female part connected to the wall, or vice versa.
  • a particular simple means for fixation is hook and loop fasteners, e.g. from the company Velcro.
  • the means for fixation may be of a more permanent type, e.g. nails or screws, whereby the risk of disconnection of the ampoule opener during use is eliminated.
  • Another aspect of the invention relates to a method for operating an ampoule opener as laid out above, comprising the steps of inserting the tip of the ampoule through the flexible opening in the insertion tube's outward-facing end until the neck portion between the tip and a body portion of the ampoule comes to rest at the flexible opening of the insertion tube, and thereafter pressing the ampoule body downwards until the tip of the ampoule snaps off.
  • the drawing figures depict the present invention and its function by way of example according to an embodiment.
  • Figure 1 shows a cross section of an ampoule opener according to a first embodiment.
  • Figure 2 shows a cross section of an ampoule opener according to a second embodiment.
  • Figure 3 shows a cross section of the ampoule opener according to the first embodiment with an inserted ampoule tip prior to it being snapped off.
  • Figure 4 shows a cross section in a subsequent step of inserting a second ampoule tip with the associated pushing in of a first ampoule tip
  • Figure 5a is a side view of the ampoule opener of Figure 1
  • Figure 5b is a front view of the ampoule opener of Figure 1.
  • FIG. 1 An embodiment of the ampoule opener is seen in cross section in Figure 1.
  • This embodiment is of unitary construction, so the ampoule opener may be a disposable unit, so there is minimum risk of contact with the contents of the container 1 of the ampoule opener. If it considered relevant the ampoule opener may be provided with an opening (not shown) for emptying the container 1.
  • On the side 4 of the container 1 an insertion tube 2 protrudes in a downward direction at a sharp angle ⁇ relative to the side 4.
  • a flexible opening 3 In the outwardly facing end of the insertion tube 2 is a flexible opening 3.
  • Figure 2 illustrates a second embodiment of the ampoule opener in cross section.
  • the ampoule opener is basically the same, but the insertion tube 2 is arranged on a lid .
  • This second embodiment can be provided by removing the bottom of the container 1 of the ampoule opener of Figure 1.
  • the lid 1 ' may be arranged above a separate receptacle for collecting the snapped off tips of ampoules, and lid 1 ' may be connectable to such receptacle by connection means (not shown).
  • Figure 3 illustrates a step of operating the ampoule opener.
  • a tip 5 of an ampoule 6 is inserted through the flexible opening 3 of the insertion tube 2, so a narrowed neck portion 7 of the ampoule 6 is positioned in the flexible opening 3.
  • the body 8 of the ampoule 6 may be pressed downwards as illustrated by the arrow.
  • the flexible opening 3 allows the ampoule to pivot about the neck portion arranged in the flexible opening.
  • FIG. 4 A subsequent step of operating the ampoule opener is seen in Figure 4.
  • a snapped off tip 5 Of an ampoule is pushed into the container 1 by the tip 5 of a second ampoule being inserted into the insertion tube 2.
  • Figure 5A and Figure 5B illustrates the ampoule opener in side view and front view. It should be understood that the relevant angle of the insertion tube could be seen as the angle relative to vertical, instead of relative to the side of the container 1 or lid .
