An improved
lumbar puncture.
An updated tool for a centuries-old procedure, that stabilizes needle insertion while simplifying CSF pressure measurement and collection.
One is definitely better than two.
Lumbar punctures are notoriously difficult and currently require a two-person team to perform. This tool streamlines the procedural effort, allowing it to be easily performed by a single individual.
Streamlined Component Management
The needle, valve, glass manometer and collection vials are consolidated into a single unit. This leaves one hand free to control the flow of fluid from the 3-way valve.
Easier Fluid Collection
Collection vials can be slid into place along a highlighted track, eliminating the need for a second pair of hands. The level of fluid in each vial is easily visible to ensure a sufficient sample is collected the first time.
A better experience for patients and doctors.
Using existing devices, physicians may need to reinsert the needle several times to ensure correct placement. This is both inefficient and frustrating for the physician and patient.
Stability and Ergonomics
Because these needles are flexible, it is difficult to maintain a straight path of insertion. This is one of the main reasons a physician may need to reinsert the needle multiple times. This tool enables a more stable needle insertion, reducing the number of attempts necessary.
Shoulder-based needle placement
Accuracy and precision of needle placement is improved by shifting from a wrist-based movement to shoulder-based one. Once the needle is inserted the device helps keep the needles trajectory straight.
Multiple hand postures supported
This tool can be used in both the right and left hand. The ergonomic curves support multiple hand sizes and postures. The shape allows for an easy, neutral grip that maximizes stability.
Prototyping
Several mechanisms, forms and materials were explored to arrive at the final design of this tool. Here are just a few of the models made along the way!
