Our group decided to focus on affordable aids for people globally, not limiting ourselves to strictly disaster relief devices. With this in mind we spoke with doctors, surgeons, and workers in Ireland to see what could be of use to the public. Teaming up with an emergency physician focusing on digit injuries, we decided to re-design a digit splint for both adults and children. The idea behind this splint is a universal fit that can be adjusted for size depending on which digit is injured and where the injury is located. 

Additionally, after reaching out to a needle exchange in Dublin, we saw the need for personal sharps bins which will aid in the secure disposal of sharps and the ability to bring them back to needle exchanges throughout the city. With this in mind, we also designed a universal sharps attachment to be secured to a standard water bottle, allowing for the safe disposal of sharps in an emergency.

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. 

 The threading of this attachment was designed to fit the standard water or soda bottle threading, taking the different threading standards into account. This quick print includes not only the conical attachment nozzle, big enough for standard needles, but also a final locking cap which hooks onto the lid of a water bottle - locking the mechanism entirely.

Personal Sharps Bin

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

 The inverted triangles located on the lid and bin itself allow for a dual-height lockable fit. The overall dimensions of the bin are 70 x 20 x 110 mm when fully closed. The flexible safety barriers at the opening of the lid allow for the insertion of syringes and sharps, without allowing them to fall out. The two options for a cover allow for a completely sealed bin or a continuous use option with the opening, available with the "One works, One Person" message - with signifies one is safely using a needle exchange.

Standard sharps bins...

are size limiting when it comes to personal use and can cost up to €7.50 for an individual bin.

Our sharps bin & attachment...

come to a combined cost of €3.70; with the personal bin costing €2.92 to fabricate and the sharps attachment and lock only costing €0.78.

Finger Splint

After talking with a trauma surgeon specialising in digit injuries - we addressed the need for a universal finger splint. 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. 

 The main support for the splint has openings on either side which allow for good visibility of wound dressings and increased ventilation. Indented grooves allow for a ring to secure the splint on the digit without applying too much pressure. These grooves have perforations which allow for one to customise the length of the splint depending on digit size and injury location. The perforations allow the user to snap off extra length without compromising the integrity of the splint. With pediatrics in mind, a small bracelet was designed which features a hook that can be connected to the splint with a piece of string - limiting the child's ability to fiddle with the splint or remove it entirely. The software, Cura, used to load the files for printing allows for the user to scale the size of the print which allows for larger or smaller prints - ideal for pediatric patients.

Universal size variations

Variations in finger size can be easily overcome in Cura by using the scaling tool.

Modular splint with...

child bracelet option. The scalable sizes allow for universal sizing for all patients, with maximum cost coming in at €0.54. The price only decreases as you scale down for pediatric cases and the bracelet costs €0.11.
