1. A medication delivery pen, comprising:
- a proximal end, and a single bore through the proximal end;
an elongated pen body assembly comprising a distal end,a needle array containing a plurality of double-sided needles, each of the double sided needles being an elongated body having a proximal needle spike at one end and a distal needle spike at an opposite end and each of the plurality of double-sided needles fully contained within the pen body assembly before and after use during an injection, the needle array configured to replace each double-sided needle after each extension and retraction of the proximal needle spike through the bore during the injection;
a cartridge having a reservoir of medicine, the cartridge being fully contained within the pen body assembly, the cartridge further comprising a needle valve positioned proximate the distal needle spike; and
an actuator on the pen body for initiating the injection, whereby the actuator is adapted to cause relative movement of the cartridge and one of double-sided needles together whereby the distal needle spike of the one of the double-sided needles is inserted into the needle valve of the cartridge and the proximal needle spike extends through the single bore; and
wherein a fluid within the reservoir of medicine travels directly through one of the needles from the reservoir through the distal needle spike and exits through the proximal needle spike when delivering medicine through the medication delivery pen;
further comprising a short range transceiver operatively connected to the elongated pen body assembly; and
an intelligent control and a display, wherein the display is positioned on the pen body assembly and electrically connected to the intelligent control.

9. A medication delivery pen, comprising:
-
an elongated pen body assembly comprising a distal end, a proximal end, and a single bore through the proximal end; a cartridge having a reservoir of medicine, the cartridge being fully contained within the elongated pen body assembly, the cartridge comprising a needle valve; a needle array containing a plurality of double-sided needles, each of the plurality of double-sided needles having a proximal needle spike and a distal needle spike, the medication delivery pen configured to replace each needle after each extension and retraction of a needle; and a needle assembly adapted to convey clean needles of the needle array towards the proximal end of the pen body assembly for delivering medication via injection and to convey used needles towards the distal end of the pen body assembly such that the plurality of needles remain fully contained within the needle assembly before injection and after injection; an actuator on the pen body for initiating the injection, whereby the actuator is adapted to cause relative movement of the cartridge and one of the double-sided needles whereby the distal needle spike of the one of the double-sided needles is inserted into the needle valve of the cartridge and then to cause the cartridge and the one of the double-sided needles to move together until the proximal needle spike extends through the single bore; and wherein a fluid within the reservoir of medicine travels directly through one of the needles from the reservoir through the distal needle spike and exits through the proximal needle spike when delivering medicine using the medication delivery pen; wherein the needle valve is positioned proximate the distal needle spike; further comprising a short range transceiver operatively connected to the elongated pen body assembly; and an intelligent control and a display, wherein the display is positioned on the pen body assembly and electrically connected to the intelligent control. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
