DESCRIPTION OF THE PREFERRED EMBODIMENT [0028] From FIG. 1 a preferred embodiment of the medical puncturing device appears. The device comprises a rigid needle 1 mounted in a needle hub 2. The needle is at the end opposite the needle hub 2 pointed or tapered so as to facilitate puncturing e.g. by the insertion of a soft cannula. The needle hub comprises a handle part 3, which is at one side connected to a shield part 4 via a hinge 5 formed as a material area with a reduced thickness. The shield part 4 has the shape of a half tube 6 having at the edges at both sides flanges 7,8. The shield part 4 comprises a pivoting handle 17. At the opposite side of the needle hub 2 in relation to the needle connection point the needle hub 2 comprises two arms 9,10 having barbs 11,12 at their opposed sides 15,16. [0029] From FIG. 2 the puncturing device appears in a side view more clearly showing the transition area 5 where the shield part 4 is pivoted in relation to the handle part 3 by a pivoting action on the pivoting handle 17 by one hand while holding the handle part 3 with the other hand. [0030] From FIG. 3 and FIG. 4 which are rear and front end views, respectively, the locking elements on the shield part and the handle part appear more clearly. Upon pivoting of the shield part in relation to the handle part these locking elements are caused to interact. [0031]FIG. 5 and FIG. 6, which are bottom and top views, respectively, illustrate the locking elements in further detail. [0032] From FIG. 7 the fastening site 14 for the rigid needle in the hub becomes apparent. The rigid needle is preferably secured in the correct position by a press fit connection or by gluing or welding. [0033] From FIG. 8 and FIG. 9 it appears that the barbs 11,12 are co-operating with the flanges 7,8 of the shield part in order to interlock the shield part in the pivoted position. The deformed material in the transition area 5 together with the bend needle provide a biasing effect between the flanges 7,8 and the barbs 11,12. The needle hereby closely abuts on the side of the half tube 6 ensuring that unintended contact with the needle is avoided. This becomes especially clear in FIG. 9 where a part of the hub is cut away. [0034] From FIG. 10 and FIG. 11 a field of use for the puncturing device appears. The puncturing device is inserted into an infusion device 18 for subcutaneous delivery of medication to a patient. This infusion device comprises a housing 19 in which a cavity 20 is provided and where a bore 21 leads medication from a pump or the like via a connector 25 to the cavity 20 where a soft cannula 22 is provided in fluid contact with the cavity 20 and where a further bore 23 covered with a self-sealing septum 24 is provided opposite the soft cannula 22. The puncturing device is inserted through the self-sealing septum 24, the cavity 20 and the soft cannula 22 and extends beyond the outer tip of the soft cannula. The puncturing device is held in place in relation to the connector 25 by means of barbs 26,27 on the shield part. When pressing the handle part 3 againts the pivoting handle 17 the barbs will release from their gripping position on the downward facing side of the connector 25 and the puncturing device may be retracted from the infusion set. The soft cannula is placed in an operational position, i.e. in a subcutaneous infusion site, by penetrating the skin and tissue of the patient by means of the puncturing device and afterwards retracting the puncturing device through the soft cannula, the cavity and the self-sealing septum. The puncturing device is not intended for further use and should therefore be folded and brought into a locked position as shown in FIG. 8 and FIG. 9 prior to discarding hereby ensuring that unintended harmful injuries caused by an exposed needle are avoided.
