Performance Results

The cartridge was tested after being received from the manufacturing company with water since water has a similar viscosity as the agent used by the surgeons. The steps for testing are summarized below: 

• Stage 1: Confirm that the water channel is sealed through the static components.

• Stage 2: Observe the water flow exiting the storage tank hole. 

• Stage 3: Confirm the oscillation fo the dynamic components. 

• Stage 4: Combine stage 2 and stage 3.

                Stage 1                                                        Stage 2                                                      Stage 3                                                                 Stage 4

Prototype Limitations

• The model cannot overcome fluid friction to pass through the needles.

• The device is vulnerable to leaking if the fluid delivery from the syringe is too quick.

Future Considerations

• The prototype would be more effective if a connector between a cartridge and pen was added for greater stabilization.

• Alternative manufacturing methods as well as injection molding are techniques that can be looked at for more advanced production for this microneedling cartridge.
