Portable Lumbar Puncture Trainer

This portable lumbar puncture trainer is designed for medical students and junior healthcare professionals for fundamental lumbar puncture skill practice. It accurately replicates key lumbar anatomical structures and clinical procedural scenarios, enabling users to systematically train essential techniques such as puncture site identification, needle angle control, recognition of the “loss of resistance” sensation, and cerebrospinal fluid (CSF) aspiration.

✔️Innovative and Portable Design:
This lumber puncture model features a lightweight, compact structure designed for mobile clinical training. The adjustable frame supports both sitting and left lateral decubitus positions for flexible lumbar puncture practice. With a built-in carrying handle, it can be easily transported and set up by a single user.

✔️Accurate Anatomical Landmarks for Precise Localization:
The LP trainer includes realistic lumbar spinous processes and iliac crests under the skin. Trainees can palpate the iliac crest and use Tuffier’s line to locate the L3–L4 or L4–L5 space accurately. It helps learners avoid blind puncture and build correct clinical judgment from the start.

✔️Realistic Two-Stage Loss of Resistance Feedback:
The internal structure is designed to replicate realistic tissue resistance during needle insertion. Users can clearly feel two distinct “loss of resistance” or “give” sensations, corresponding to the needle passing through the ligamentum flavum and then the dura-arachnoid membrane.

✔️Visible CSF Flow for Real-Time Confirmation:
When the needle correctly enters the subarachnoid space, clear simulated cerebrospinal fluid (CSF) flows immediately. This visual feedback helps trainees confirm accurate needle placement and depth, while also allowing practice of CSF collection and pressure measurement techniques.

✔️Versatile Use in Clinical Training:
This lumbar puncture trainer is used in medical schools, nursing programs, and simulation labs for lumbar puncture training. It is ideal for OSCE exams, classroom teaching, and hands-on practice for students and junior clinicians, supporting repeated independent learning.
