Can air for example be discharged by regulating dosage and from conveying equipment and casing 20 in the conveying equipment for being attached to needle hub
To prepare to use for technical staff.In this stage, needle hub 16 and conveying equipment can be turned back in corresponding outer cover 22, Zhi Daozhun
Get use ready.It can be that each pen needle assemblies being located in corresponding wellhole 94 prepare conveying equipment.Corresponding actuator is pressed
Button 122 may include such as label of number or letter, to specify selected patient, include the dosage or medicament in conveying equipment.
Each of each wellhole formed by clamping components 46 and 48 wellhole receives a pen needle assemblies, sets for preparing conveying
It is standby for using.In this way it is possible to prepare multiple conveying equipments simultaneously for using, wherein each conveying equipment is located in
In corresponding wellhole by the label mark in actuator button.
Each of each conveying equipment conveying equipment can be used for conveying medicament to patient.After usage, needle hub 16
Be inserted back into while being still attached on conveying equipment in corresponding outer cover 22, wherein conveying equipment can with it is corresponding
Needle hub separation, and used needle hub is stayed in the wellhole formed by clamping components 46 and 48.Then, it can press for corresponding
The associated actuators button 122 of wellhole 94, so that the main body 136 of ratchet mechanism 124 pivots downwards, by the spine in main body 136
Pawl 150 is separated with the pawl 172 in the main body 166 for the ratchet component for being attached to removable clamping components 48.Then, spring 182
Removable clamping components 48 are biased to open position, so that used pen needle assemblies be allowed to separate with clamping components 46 and 48
And it falls into pallet 34 so as to safe disposal.Then manually removable clamping components 48 can be shifted onto closed position, to connect
The pen needle assemblies taken in the fresh.In this way, used pen needle assemblies can be discarded into pallet after use, without
Technical staff handles needle hub, thus reduces the risk that needle pierces during using and disposing conveying equipment and needle hub.
In another embodiment, extractor can be formed by the sheet metal clip for being attached to pedestal, and wherein clip includes sharp
Edge is to engage inner shield part.Extractor can have the slot of substantially keyhole, which has widened generally circular opening
It is less than the longitudinal of circular open diameter with width and extends opening.The size of circular open can be slightly larger than the outermost ruler of inner shield 24
It is very little, allow inner shield without interferingly passing through.The distal end of longitudinal opening may include inwardly projecting extremely relative to circular open
A few tooth.Tooth can have inclined surface, which forms sharp tip and in direction updip generally downward
Tiltedly, to allow inner shield part 24 to slide on tip and inner shield part is prevented to remove in an upward direction.Tooth can be enough
Other vessel flexible, inner shield part being pushed through the opening to enter in pallet or shell.
Can be by the way that new pen needle assemblies placement be repeated these steps in the housing, and delivery pen can attach
To needle hub.New needle hub with inner shield part 24 can be inserted in the opening of extractor, wherein before the tip engagement of inner shield part
The top of one shielding part, so that the flexible edge that previous shielding part passes through spring clip is moved in downward pushing.Then, inner shield part 24
It can drop downward into pallet.
In another embodiment shown in Figure 21 and Figure 22, outer cover 22 can re-attach needle hub 16, without inciting somebody to action
Needle hub is separated with delivery pen.The delivery pen for being attached to needle hub 16 can pass through lantern ring and shell and be inserted into, so that needle hub 16 is received
In outer cover 22.Then pressable actuator 108 discharges outer cover 22 to separate clamping components.It is then possible to be protected in outer cover
Delivery pen is extracted in the case where casing out, to avoid unexpected needle thorn.
