NeoTap
Neonatal Lumbar Assistance Puncture Device
UTDesign Capstone 2024 - 25
NeoTap (previously known as Wavy Baby) is the result of my capstone project during my undergrad at UT Dallas. My team and I developed this device from early problem definition and conception through prototyping, iteration, and final design.
I completely owned the design and configuration of the device, and also determined force-measuring probes as the best detection modality for our requirements and constraints. Along with technical work, I also managed regular communication with the client, mentor, and capstone program directors.
Background
This device was designed to assist pediatric medical professionals in performing a Neonatal Lumbar Puncture, commonly known as a Spinal Tap.
The current, unassisted standard of care is inaccurate as it relies solely on the doctor's senses, and the current method of assistance is by using an ultrasound to be able to visualize the intervertebral space. These methods require extensive training, can be extremely expensive, and cause unnecessary pain to the patient if the procedure fails.
Our Solution
This device aims to solve these issues by offering an affordable, portable, user-friendly design that will improve the accuracy of Neonatal LP's through quantitative feedback that can be used effectively by providers with a minimal amount of training.
The device works by comparing force values measured from probes that are placed along the spine, and directs the user to move the device longitudinally along the spine until an acceptable insertion location is found within a specified threshold.
The final iteration of the prototype (at the time of submission) took into account ease of use and repairability with the following 5 major characteristics:
- Rechargeable Battery Port
- Lightweight and Portable
- OLED Screen that displays real-time commands
- Angle lines allow for more precise insertion
- Force probes detect different force values

Future Developments
As of 2025, we are working to secure a patent for our prototype and develop our technology into a market-ready product that can be purchased by hospitals, clinics, and even individual medical providers by improving material quality, components, and configuration.
