Definitions

  • the invention concerns a cannula eliminator of the type indicated in the introduction to claim 1.
  • a syringe is filled by pulling up the plunger in a preparation room and bringing it to a patient in his room.
  • the retractable cannula (which is not intended for use on the patient) should be placed in a cannula bin, which is the special waste bin.
  • a cannula bin which is the special waste bin.
  • EPA 1455075 there is further disclosed an apparatus for destroying cannulas using the well-known principle of melting between two electrodes.
  • the apparatus which is described in this publication has a feed-in aperture where electric contact is created to the needle of the cannula and a lower electrode element with an inclined plane with which the needle of the cannula makes contact, thus initiating the electrical destruction.
  • US Patent 4628169 there is disclosed a destruction apparatus of the general type wherein there is a contact between the cannula feed-in aperture and an electrode further down.
  • the apparatus is equipped with a refuse drawer which can be pulled out.
  • US Patent no. 4965426 an apparatus is described in which the electrodes are inserted between two steering rollers and come into contact with a spring electrode and a lower electrode. Thus in this case rollers are used for steering the cannulas into the correct position between two electrodes.
  • the object of the present invention therefore is to provide a new cannula eliminator, which destroys cannulas in a simple and reliable manner and wherein the treatment of waste also takes place in a closed system where no personnel come into contact with the waste.
  • the object of the invention is to avoid the above-described problems and to provide an improvement in relation to the known devices.
  • fig. 1 is a perspective view which illustrates a cannula eliminator according to the invention and its main components
  • fig. 2 is a cannula eliminator according to fig. 1 where the power part and the combustion part are separated,
  • fig. 3 is a section of the cannula eliminator in fig. 1 , illustrating the method of operation
  • fig. 4 is a perspective view which illustrates the upper electrode holder system in the eliminator according to the invention
  • fig. 5 is a further partial section of an eliminator according to the invention.
  • fig. 6 is a view illustrating the lower electrode device in an eliminator according to the invention.
  • the cannula eliminator according to the invention has three main components, viz. a combustion part 2 which is placed on a power part 1 which includes an operating part 3, and an external waste container 4.
  • the voltage is supplied to the combustion part via contacts 5.
  • a cannula with or without syringe is inserted into a downwardly-leading funnel 7 in the combustion part 2.
  • the cannula is steered by means of a mounting bracket 20 (fig. 3) to an upper electrode holder 18 and fits between rod electrodes 19, which are pressed together by compression springs 27 (fig. 4).
  • the rod electrodes 19 are electrically connected to transfer contacts 5.
  • the cannula is pressed further down into the combustion chamber 38 until it meets the rotating lower electrode 14 which is driven by a motor 13 and a gear 24 (fig. 5).
  • the lower rotating electrode is connected to sliding contacts 17, which in turn are connected to the transfer contacts 5.
  • the rotation of the lower electrode 14 causes the cannula to be pressed against the rod electrode 19, resulting in a short circuit (arc) between the lower electrode 14 and the upper rod electrode 19 inside the combustion chamber 38.
  • the combustion starts at the top of the lower electrode 14 at a temperature of approximately 2200°C and the waste which after the combustion is in the form of small pellets, is steered down in a drainage track 36 on the lower electrode 14.
  • the waste falls down on to a discharge plate 23 and is gradually cooled while being passed downwards and running out into an external waste container 4, where the temperature of the waste in the meantime has been reduced to a temperature in the order of 40°C -60°C .
  • the cannula is pulled down until the plastic lip stops against the rod electrodes 19 and the contact between the lower electrode 14 and the rod electrode ceases.
  • the steel part of the cannula is now removed, completely burned down and only the Luer cylinder remains on the syringe.
  • the Luer cylinder with the actual syringe mounted/not mounted is pulled straight up through the funnel 7 and the steel part is removed.
  • the Luer cylinder is sealed, closed by the melting process and the syringe cannot release any medicine remaining therein due to the vacuum which now exists within the syringe.
  • the external container 4 is connected to the combustion part 2 via a connecting pipe and thus can be exchanged in a simple manner.
  • the container 4 is pulled right off the waste pipe 9 which cooperates with a lock washer 10 on the container 4.
  • a double-sided tape which is attached to the waste container 4 is released and folded around and over the filling aperture and the lock washer 10.
  • the used waste container is thereby sealed and can either be treated as ordinary waste or sent for recycling.
  • Typical examples of places where the device according to the invention can be used are in dentists' surgeries or in hospitals.
  • a dentist who gives a patient an injection merely has to turn round immediately after the injection to his cannula eliminator which is located on a table and destroy the syringe needle forthwith.
  • the syringe can thereby be discarded in ordinary waste without risk of infection either for the dentist or the cleaning personnel.
  • the installation of the power parts 1 in a preparation room and a patient's room respectively are the natural places in order to achieve maximum security against puncture wounds to the user. Between these user locations, therefore, the user only has to carry the eliminator or combustion part 2 which is of the lightweight type.
  • This combustion part 2 is placed on the power part 1 before the syringe is employed.
  • the power parts can be placed in a stationary position in suitable locations at which a transportable combustion part can be connected.
  • the user will always be able to destroy/melt (at 2200°C) all hypodermic cannulas directly at the user location. It will be possible to seal the syringe hermetically, thus ensuring that no cytostatikum can leak out. The syringe can thereby be downgraded to ordinary risk waste and deposited in a waste container suited to this purpose in the patient's room.
  • the user can be sure that the waste from the melting process (small pellets) is free of all infection.
  • the destruction can take place so close to the user location that the risk of puncture/infection is reduced to a minimum.
  • the amount of infectious waste is thereby reduced.

Abstract

Dispositif pour la destruction de canules, d'aiguilles de seringue ou analogue, comportant un appareil de combustion (2) muni d'un orifice (7) pour l'introduction de canules ou d'aiguilles de seringue. Une électrode supérieure (19) et une électrode inférieure (14) tournant autour d'un axe horizontal sont montées sous cet orifice (7). Les électrodes sont connectées à une unité d'alimentation (1) constituant une source d'énergie suffisamment puissante pour faire fondre les canules ou aiguilles de seringue. L'appareil de combustion (2) est relié par l'intermédiaire d'une surface inclinée de transport à un récipient collecteur d'aiguilles détruites. L'électrode supérieure de l'appareil de combustion est composée de tiges horizontales (19) sollicitées par ressort. L'électrode rotative inférieure (14) est pourvue d'une surface circonférentielle assurant l'évacuation des particules en fusion. La surface de transport de l'appareil de combustion s'étend jusqu'à un orifice de décharge (9) muni de préférence d'un rebord. Un récipient pour déchets (4) peut être relié à l'orifice de décharge (9) au moyen d'un orifice adapté pour entrer en contact hermétique avec ce dernier. L'orifice du récipient pour déchets peut être obturé, ce qui permet d'évacuer les aiguilles de seringue dans un récipient hermétique.
