Definitions

  • the present invention relates to a device for collection and disposing of used injection, or sample-withdrawal, needles for avoiding lancing injuries to medical personnel.
  • HIV-infection and infections of all hepatitis-types have turned lancing injuries into a considerable problem.
  • Bloodborne toxoplasma infections are also a reality for pregnant women with these injuries.
  • Needles of a certain type are usually used during sample- withdrawal in which the needle is screwed into the remaining sample-withdrawal device.
  • the needle When the needle is to be removed, it must therefore be screwed from, for example, the sample-withdrawal tube, which is normally effected using a special tool, usually being of the unwieldy type as mentioned above.
  • the device is light and easy to carry and, from a production point of view, particularly economical.
  • the above-mentioned object is achieved by means of the invention providing a device for collection and disposing of used injection, or sample-withdrawal, needles, which device is characterized in that the opening includes a pierced hole which permits the insertion of the widest part of the needle, and at least a through-slot in communication with said pierced hole whose surrounding facing edge regions provide resistance during removal of a needle from an injection syringe and during the unscrewing of a sample- withdrawal needle from a sample-withdrawal tube, and in that at least one flexible, elastically-returnable tongue is provided in said pierced hole, which tongue is dimensioned so as to permit the introduction of needles exteriorally and to close said pierced hole at least partially so that collected needles are prevented from exiting the collection container.
  • Fig. 1 shows a situation leading to injury during a routine work phase
  • Fig. 2 shows another situation leading to injury during a known work phase.
  • Fig. 3 shows an embodiment of a collection container according to the invention
  • Fig. 4 shows the container according to the invention when it is being carried in a top pocket
  • Fig. 5 schematically shows how a needle is introduced into the collection container
  • Fig. 6, 7 show how a needle is separated from an and 8 injection syringe with the help of the invention
  • Fig. 9 shows a so called sample-withdrawal needle connected to a sample-withdrawal tube, only a part of which is shown for the sake of clarity.
  • Fig. 10 shows the container from above with a sectioned sample-withdrawal needle introduced into the slot of the opening
  • Fig. 11 shows the container from above with a sectioned injection needle of the screw or bayonet-fixing type introduced into the space between the two tongue elements;
  • Fig. 12 shows in perspective how the sample-withdrawal tube is turned whilst the needle's flanges are abutted against the edge regions of the slot;
  • Fig. 13 shows how the sample-withdrawal needle finally drops into the container.
  • the figure reference numeral 1 in Fig. 3 generally denotes a collection container according to the invention.
  • the collection container 1 has an elongated cylindrical shape and is provided with an attachment member 2 for retaining the container 1 on an article of clothing 3 of the wearer (see Fig. 4) .
  • the attachment member 2 is in the form of a resilient clip 4 of metal or plastic, whereby the clip is of the known type which i.a. is used on pens.
  • the collection container 1 is hereby intended to be easily carried in, for example, a top pocket 5 of said article of clothing 3.
  • the clip 4 is integral with a cover portion 27, which is intended to shut a container portion 28 of the collection container 1.
  • the cover portion 27 is, for example, made from a somewhat elastic material, such as plastic, and is provided with a downwardly projecting collar 29 which surrounds the opening edge of the container portion.
  • the container portion 28 is, in the shown example, cylindrical with a flat bottom by means of which the container can be stood on a surface.
  • the container portion's opposite end has an opening which is partially closed (see below) by the cover portion.
  • the circumferentially extending edge of the opening is hereby provided with an edge bead.
  • the cover portion is snapped in below this edge bead by means of the collar having an inwardly facing edge bead.
  • the clip is gripped with two fingers and the cover portion is pushed up with a lever action so that it is loosened and the container can be emptied and reused.
  • the collection container 1 further presents means 7 for separating a needle 8 from an injection syringe 9 or similar, as can clearly be seen from Fig. 5.
  • Said means 7 is in the form of an opening 11 in the collection container 1.
  • the opening 11 comprises a substantially triangularly shaped pierced hole 12 which permits the insertion of the widest part 13 of the needle 8.
  • Two flexible, elastically returnable tongues 15 are provided in said pierced hole 12, whereby collected needles 8 are prevented from exiting the collection container 1.
  • the tongues 15 are substantially triangularly shaped in such a way that the triangle's one side 17 is integrally connected with one of the sides 18 of the triangle of the pierced hole 12.
  • the opening 11 further includes a through-slot 14 in communication with said pierced hole.
  • the slot's 14 surrounding facing edge regions 16 hereby provide resistance during removal of the needle 8 from the injection syringe, as can be clearly seen in Figs. 7-9.
  • the facing edge regions 16 are hereby substantially parallel with each other.
  • the collection container 1 is suitably substantially made from plastic or metal.
  • Figs. 6, 7 and 8 The method of separating a needle 8 from an injection syringe 9 is clearly shown in Figs. 6, 7 and 8.
  • the collection container is shown here in a schematic sectioned view and it can be seen that the needle 8, still affixed to the injection syringe 9, is inserted into the collection container 1 through the triangular pierced hole 12 (see Fig. 7) of the opening 11 so that the flexible tongues 15 are bent and pressed down by the widest part 13 of the needle 8.
  • the tongues 15 elastically spring back to the starting position according to Fig. 7.
  • the return springing of the tongues 15 hereby occurs in such a way that the injection syringe 9 and the needle 8 are simultaneously pushed sideways to the right in Fig. 7 along the slot 14 due to the spring effect.
  • This favourable effect is due to the particular placing of the tongues 15 along the triangle sides 18 of the pierced hole 12.
  • the edge regions 16 hereby act as abutments and when the injection syringe 9 is further pulled upwardly, and/or lightly displaced to the right according to the arrow 22 in Fig.
  • a needle 8 for sample-withdrawal applications is shown in Fig. 9.
  • the sample-withdrawal needle 8 presents a threaded region 24, as can be seen from Fig. 12.
  • the needle 8 in Fig. 9 is shown screwed to a sample-withdrawal tube 25.
  • the attachment part 23 of the sample-withdrawal needle 8 is further provided with radially outwardly extending wings 26, which can be for example four in number.
  • the wings 26 are used when the sample-withdrawal needle 8 is to be removed from the sample-withdrawal tube 25 after use by unscrewing.
  • said needle 8 When unscrewing such sample-withdrawal needles 8, said needle 8 is inserted into the slot 14 of the collection container 1 so that the wings 26 of the attachment part 23 abut against the facing, substantially parallel edge regions 16 of the slot 14. This can clearly be seen from Figs. 10 and 11.
  • the sample-withdrawal tube 25 is unscrewed via the threads 24.
  • the tube 25 is thereafter moved across to the tongues 15 and pulled upwardly, whereby the needle 8 is loosened and collected in the container 1.
  • the wings 26 serve in this instance as abutments for the unscrewing of the sample-withdrawal tube 25.
  • the gap between the two tongues 15 is used as a slot 19 to accommodate the type of injection needle 8 which is commonly used in, for example, USA and which is provided with a screw or bayonet attachment according to the above described sample- withdrawal needle 8 and also has corresponding wings.
  • This type of injection needle has, however, smaller dimensions than said sample-withdrawal needle 8, and so unscrewing cannot take place in the slot 14. Since the gap between the tongues 15 is adapted so that such an injection needle 8 can be inserted therein according to Fig. 11, the needle 8 can thereafter be unscrewed in the same way as the sample- withdrawal needle 8 is unscrewed in the slot 14.
  • the facing sides of the tongues 15 which form the slot 19 are substantially parallel according to that shown in Fig. 11, the object being to provide abutment for the unscrewing.
  • the tongues 15 are preferably somewhat angled downwardly towards the free ends 20 in such a way that the injection needle 8, after unscrewing, downwardly displaces the tongues without difficulty by a downward pressing movement so that the needles can finally be loosened and fall down into the collection container 1, the needle usually having a flange which means that it cannot drop down without the tongues being bent downwards.
  • the opening should be, or is , so dimensioned so that no needle can pass through without a certain force being applied so that the tongues 15 are displaced.
  • the container should have such a transverse size that the needles cannot turn about in the container, but instead remain with the tip pointed downwardly. Accordingly, no tip can ever project through the opening 11 and injure the user.
  • the pierced hole 12 can be shaped in a number of different ways, such as circular or rectangular.
  • the collection container 1 can be provided with a closeable cover of known type for safe disposal of the needles 8.
  • the slot 14 can be extended with a slot which forms a continuation of the gap between the tongues. In this extended slot, which is narrower than the slot at the opposite end, the above described needle 8 can be inserted for unscrewing and thereafter sidewardly displaced to the tongues where the needle is pulled off.
  • the edges 16 can be chamfered with increasing edge thickness in a direction from the tongues 15 which simplifies detachment of the needles.
