    Detailed Description of a Preferred Embodiment of the Invention The cannula remover shown in Figs. 1 and 1A generally comprises a container 1 open at the top for receiving the needles removed from a syringe S and a separation mechanism 5 arranged in a stationary part 3 of the cannula remover.
    According to the embodiment shown, the stationary part 3 consists of a lid which is applied to the container 1.
    As can be seen from Fig. 2, a funnel-like member 4 is arranged on the underside of the lid 3, the funnel-like member 4 guiding down separated needles K in the container 1.
    As can be seen most clearly from Figs. 2-7, the separation mechanism 5 comprises a receiver part 7 rotatably suspended in a first opening in the lid 3 which is intended to receive a syringe S whose cannula K is to be separated from the syringe in general.
    According to the embodiment shown, the receiving part 7 is generally in the form of a cylinder, two shafts 9 included in the Separation Mechanism 5 being accommodated in the receiving part 7 and extending in axial direction out from the receiving part 7, on either side thereof. The ends of the shafts 9 are mounted in the lid 3, which is clearest from Figs. 3 and 6.
    This arrangement means that the shafts 9 support the receiver part 7 relative to the cover 3 and that the receiver part 7 can rotate a certain angle relative to the cover 3.
    As can be seen generally from Figs. 2-7, a holding member 10 is formed in the receiving part 7, wherein according to the embodiment shown the holding member 10 is in the form of a sleeve which is intended to receive a syringe S which is provided with a cannula K, see e.g. Fig. 3. The sleeve 10 is rigidly attached to the receiver part 7 in general. According to the embodiment shown, the receiver part 7 is generally cylindrical.
    The receiving part 7 has an internal free space 11, the cannula K of the syringe S accommodated in the receiving part 7 extending into this free space 11. According to the embodiment shown, the free space 11 penetrates the periphery of the receiving part 7 along almost half the circumference of the generally cylindrical receiving part 7. The free space 11 is defined by two parallel walls which have an extension perpendicular to the longitudinal direction of the shafts 9. A stop 8 is defined where the inner space 11 breaks through the periphery of the receiver part 7 on one side thereof. The lower open end of the holding member 10 communicates with the free space 11 via a second opening 12.
    The separation mechanism 5 comprises an engaging member 13 which according to the embodiment shown generally has an elongate shape. In Figs. 8A ~ 8E, the engaging member 13 is shown separately.
    The engaging member 13 has a fork-shaped first end 14 and an opposite second end 15 which is provided with a first through hole 16. In an intermediate area the engaging member 13 has a second through hole 17 which is composed of two portions with different diameters, whereby a ledge 18 is formed in the transition between the portions of different diameters. The function of the second through hole 17 will be described below.
    The fork-shaped first end 14 of the engaging member 13 has two opposite edge portions 19 which are parallel and spaced apart. The edge portions 19 are relatively sharp, i.e. they are basically designed as edges. Preferably, the engaging member 13 is made of metal, whereby in particular the edge portions 19 can be made of hardened steel. According to the longitudinal section shown in Fig. 8B through the engaging member 13, the edge portions 19 have a certain inclination relative to the longitudinal direction of the engaging member 13. The final design of the fork-shaped end 14 has been done empirically. 3, 5 and 6, the engaging member 13, via the end 15 facing away from it. As can be seen most clearly from Fig. 2, the fork-shaped end 14, is pivotally attached to a support member 20 which is fixedly connected to the stationary part / lid 3. The pivotable the fastening is realized by means of a pin 21 or the like which extends through the first through hole 16 and holes in the support member 20. In order to resiliently position the engaging member 13 in the desired position, a screw 22 is arranged in the second through hole 17 and the head 23 of the screw 22 abuts the ledge 18 of the second through hole 17. The shaft 24 of the screw 22 extends through a third through hole 25 of the support member 20 and with an arrangement of spring, washer and nut causes the engaging member 13 to assume a desired starting position where the engaging member 13 extends obliquely upwards towards the cannula. K, the arrangement with spring washer and nut allowing the engaging member 13 to pivot about the joint 21 at a limited angle in connection with a cannon 1 K is separated from the syringe S. In this context it must be stated that the stop 8 of the receiver part 7 is located in connection with the engaging means 13, i.e. the stop 8 and the engaging member 13 are located on the same side of the shafts 9. The cannula remover according to the present invention operates in the following manner. The syringe S from which the cannula K is to be removed is placed in the holding member 10 of the receiving part 7, the cannula K being accommodated in the internal space 11 in the receiving part 7. The syringe S then assumes the position shown in Figs. 3 and 4. In this context, it should be mentioned that the cannula K is normally connected to the syringe S by means of a threaded connection.
    As can be seen most clearly from Fig. 3, the separation mechanism 5 also assumes a starting position, the receiving part 7 having the holding member 10 directed upwards and the engaging member 13 abutting in its lower part against the support member 20.
    The operator now grasps the part of the syringe S projecting from the receiving part 7 and rotates the receiving part 7 from the position shown in Fig. 3 to the position shown in Fig. 5, the fastening part of the cannula K being partly occupied between the edge portions 19 of the fork-shaped end 14, i.e. the fork-shaped end 14 engages the fastening part of the cannula K. In connection with the edge portions 19 engaging the cannula K, the edge portions 19 intersect in the fastening part of the cannula K. Upon continued rotation of the receiving part 7, the stop 8 comes into contact with the engaging member 13 and in the final stage of the rotation of the receiving part 7, the stop 8 will displace the engaging member 13, which is thereby pivoted slightly from the support member 20 around the pin 21. This is illustrated in Fig. 6. This pivoting of the engaging member 13 causes the fork-shaped end 14 to be displaced away from the syringe S and the cannula K is pulled off from the syringe S, whereby the cannula K falls into the container 1. This is done against the action of the spring. In this context it should be mentioned that in connection with the engaging means 13 pulling the cannula K from the syringe S, there will be a certain demolition of the cannula K which means that it can not be reused unauthorized.
    Normally there is a demolition of the internal thread that the cannula K has.
    Once the needle K has been removed from the syringe S, the syringe S can be used again by fitting an unused needle K.
    When the cannula K has been removed from the syringe S, the receiving part 7 is moved back to its initial position, see Fig. 2, and the engaging means 13 returns to its initial position through the arrangement with spring, washer and nut.
