What are the components of a Safety Syringe Device (SSD)?
Pre-filled syringe: syringe and stopper
Plunger
Ultrasafe Plus passive needle guard assembly
Finger Flange
Describe the assembly of the Safety Syringe Device (SSD)?
- Threading of the plunger rod into the plunger stopper of the prefilled syringe
- Insertion of the prefilled syringe (with plunger rod) into the needle guard assembly
- Attach the finger flange.
What are the plunger colours for the Safety Syringe Device (SSD)?
Purple - Beli
White - Mepo (and all others that come through)
Beli has differing registered details therefore purple
Give some components and some attributes for the Safety Syringe Device (SSD)?
Plunger rod
It is screwed in without moving the stopper (vertical or rotation)
○ <1mm down
○ 0mm up
○ <180 degrees rotation
○ Max 1mm gap between rod and stopper
Flange
Can be operated with or without - more for ergonomics
Failure to clip body and flange together doesn’t impact device function
Describe the component assembly loading of the SSD with the equipment?
Pre-filled syringe tub in manually loaded onto a conveyor system for automatic picking by robot
Plunger rod and finger flange - automatically fed into machine via bowl feeders
Ultrasafe Passive Plus needle guard (body) - loaded into the equipment in a tray as received from supplier
Describe the assembly of the SSD with the equipment - post component loading?
Robots pick components / sub-assemblies and load onto conveyor system, orientate into ‘pallets’ on machine
Sensors and vision systems check the all components for certain characteristics/conditions
100% components are checked, if anything doesn’t satisfy (assembly positions/distances and forces/torques) they will be automatically rejected
What are some Essential performance requirements (EPRs) / CQA of the SSD?
Delivered Volume
Force to remove the RNS
Peak Break loose force
Peak Glide force
Needle Guard lockout
Force to overcome lockout
Needle safe distance
Container Closure Integrity
What is the Break loose and Glide Forces?
Break-loose force: The initial force required to overcome the plunger’s static friction and start moving it inside the syringe barrel
Glide Force:
The continuous force required to keep the plunger moving smoothly through the syringe barrel after break-loose
What is PAR?
PAR - Proven acceptable range/value (for assembly)
What are some Critical process parameters that impact quality attributes / CQA for the SSD?
Position of the needle shield (RNS) on the prefilled syringe (PAR: ≤1.5mm)
Plunger rod torque (PAR: 0.07 Nm or ≤ 900 mA) / rotation (Upper Limit 1450°)
Position of the plunger rod relative to the plunger stopper (PAR: ≤ 1.0 mm)
Syringe insertion force (5 – 35 N) / position (11.7 – 13.3 mm)
What are some of the most critical operational causes of the SSD TRA?
RNS displacement
Colour band inspection
Plunger rod threaded into the syringe: torque, stopper height/fill volume, misalignment of stopper (non-parallel)
Gap between plunger rod and stopper
Syringe inserted into the SSD: force and assembly position
Give some information regarding the YpsoMate device?
Both Hypak and Neopak are used in the 1ml
Two types of devices Nominal Strength Spring (NSS) and High Strength Spring (HSS) device
YpsoMate NSS device and YpsoMate HSS device
Assembled on both CP07 and CP20
Assembly process and CPPs are identical for both NSS and HSS devices
Only difference is the drive unit insertion force limit which is (30-150N) on CP07 and (30-185N) on CP20
What are the components of the YpsoMate device?
Primary container - Syringe and stopper
YpsoMate Autoinjector
Drive unit
Syringe unit
For the drive unit to work the plunger length has to be the correct size for the fill volume (only do 1ml in YpsoMate)
Give the brief assembly of the Ypsomate device?
- Removal of the drive unit.
- Insert syringe into the syringe holder
- Insert the syringe holder into the syringe unit
- Insertion of the drive unit
Give an in depth assembly of the Ypsomate device?
-Remove the drive unit from the syringe
-Align the syringe unit, fix the syringe unit into place across the window area
-Insert the syringe into the syringe holder
-Push the syringe into the syringe holder until the snap-in finger elements snap-in correctly
Push the syringe until the syringe holder snaps into the housing, releasing the fixing across the window area
-Align and insert the drive unit into the housing of the syringe unit
-Push the drive unit into position until the end cap snaps into the syringe unit
Describe the component assembly loading of the YpsoMate with the equipment?
Tray of syringe unit sub-assemblies is loaded into the equipment as received from supplier
Pre-filled syringe tub in manually loaded onto a conveyor system for automatic picking by robot
Sensors and vision systems check the all components for certain characteristics/conditions
100% components are checked, if anything doesn’t satisfy (assembly positions/distances and forces/torques) they will be automatically rejected
All assembly data are recorded and available on OEE toolkit or Illuminate systems
Assembly data for specific devices is accessed through the 2D code on the device
Describe how the YpsoMate device actuates?
Syringe housing holds syringe by the shoulder
Removal of Cap removes the RNS
Needle cover sits on the skin and slides as the device is pushed down
Legs of needle cover push back the lock sleeve
The release latch is pushed out by the force of the plunger rod and spring into the recess and the plunger rod pushes forward by the force of the injection spring
Once actuation is complete the cover is locked in place by the release of the arms being located in the recess
They are unable to return as the plunger rod is now in place beneath
What are some Essential performance requirements (EPRs) / CQA of the YpsoMate?
Force to remove cap
Actuation Force
Needle guard lockout
Force to overcome lockout
Needle Extension
Needle Safe Distance
Holding Force
Start of Injection Click
End of Injection Click
Container Closure Integrity (CCI)
