2018 PROJECTS 

PERSONAL SHARPS BIN

After speaking with a needle exchange in Dublin, 2018’s BB-8 group decided to design a personal sharps bin that can fit in one's pocket. By adding specific features to the design, they were able to create a lockable and safe pocket-sized sharps disposal

 

HINGED DRILL CENTRIFUGE

This centrifuge design allows for the blood vials to swivel up and down with the motion of a drill to minimise mixing of the separated blood when stopping the drill. This design incorporates screws, nuts, and washers that are easily obtained in a hardware store to ensure the longevity of the part. This design can be used with either a bench drill or a hand drill; however, the hand drill may require longer centrifugation time due to a decrease in the revolution per minute capabilities.

UNIVERSAL SHARPS ATTACHMENT

This quick-print allows for the safe disposal of sharps into a standard water bottle. The threading was designed so to fit the most common water bottle caps and provides a snug fit without the risk of displacing easily. The conical opening facilitates easy placement of sharps into the gap without leaving anyone at risk of hurting themselves upon dropping the sharp. 

 

STATIC DRILL CENTRIFUGE

This centrifuge design is easier to print than the hinged drill design since it is printed as a single part. The tubes are held at a 45° angle to minimise mixing during centrifugation. This design can also be utilised with a bench or hand drill and has the same limitations as the hinged design.

MODULAR FINGER SPLINT

After talking with a trauma surgeon specialising in digit injuries - the need for a universal finger splint was addressed. By adding perforations at different intervals, the splint has the ability to have a customised length. Through the addition of a connectable bracelet, which limits the ability of children to remove splint, this universal splint has both adult and pediatric patients in mind. 

 

MANUAL DRILL CENTRIFUGE

This centrifuge design utilises the power generated by untangling the string to rotate the centrifuge with a six Eppendorf tube capacity. This design was eliminated since the centrifuge changes directions mid-spin and mixes the blood, inhibiting separation of the blood constituents.

 

SPIROMETER

The incentive spirometer was designed as a means of encouraging you to take a slow Sustained Maximal Inspiration (SMI). The hole diameters were determined through calculations to allow for a flow rate of 600, 900 and 1200 cc/sec in the tubes. The ball in the last tube is the hardest to lift and the design recommends printing this ball in a different colour for better visualization of the goal for the patient. 

HEAD LAMP ATTACHMENT DEVICE FOR MOBILE PHONE

This device allows for a mobile phone to be mounted on someone's forehead to use as a flashlight. The holder is composed of three parts that can be printed together: the forehead mount, the top clamp and the bottom clamp.

PROSTHETIC HAND

A prosthetic arm/hand attachment for below-the-elbow amputees, which uses the bending motion of the elbow to actuate the bending gripping of the hand, restoring functionality, self-esteem and normality for amputee victims.
