We will have a motor that will translate rotational motion into linear motion. We will have an LCD screen connected to the circuit so that the force can be read. As a certain force is met, the motor will start to spin. The potentiometer will allow us to adjust the LCD brightness making it customizable for each user. As an alternative, an LED can be incorporated into the circuit so that it can be easier for injectors to know when the syringe is still making its way down. For the force sensor portion, we will have 3 conductive materials that will be attached to alligator clips. This will allow the pressure from a person's thumb to be detected and measured by the LCD screen. As a certain force threshold is met, the motor will start to spin. Since the motor is connected to the screw, the screw will go down as a result of the rotational motion. The casing build from ABS will allow the material to be stable in the person's hands as well as making it smooth in the user's hands. This ABS 3D printing material comes in many types of colors, which makes our design more attractive for customizability. The purpose of the casing allows the wires and circuity to be hidden from the user making the design sleek. Near the bottom, this is where the syringe will attach. The middle part of the syringe will be stabilized inside the grooves. There will also be a hole where the screw will attach to the top. This allows the syringe to move down. Moving back up to the top, users will place their thumb to apply pressure to get the motor started. This finger placement is a comfortable mechanism as there are grooves at the top and bottom to ensure that no slipping will occur. Making this syringe handling aid gave us a new idea. Since the casing was bigger than intended, we thought it would be a good innovation to hook up these automated syringe handling aids on walls. We would place patients at a certain distance away from the wall. Using a push-button, the patient can sit and get injected. This has a real-world application as seen in the mass vaccination challenge seen with the Covid-19 pandemic.
