Educational-use note: anatomical skills trainer — educational equipment for procedural training; not a medical device or a pharmaceutical product and contains no medicinal ingredients (manufacturer's product-page notice). Simulated marrow fluid is a training material only. Confirm the full package (included accessories, replacement skins/fluid refills, weight and dimensions) with the specification sheet before ordering.
1. Why Bone Marrow Aspiration Needs Dedicated Training
Bone marrow aspirate and trephine (BMAT) biopsy is a commonly performed procedure in hematology-oncology practice and is fundamental to the diagnosis of many hematologic pathologies (Yap et al., 2015; Vander M et al., 2021). Yet it is a technically demanding invasive skill:
● It requires precise surface-anatomy localization, controlled needle advancement through cortical bone, and correct aspiration technique — none of which can be practiced on patients without risk.
Complications are uncommon but real
● — and when they occur they can cause significant morbidity and mortality (Yap et al., 2015).
● In pediatric patients the stakes are higher: smaller anatomy, thinner cortices, and a frightened, moving child. Training on the commonly used pediatric site — the child's leg (proximal tibia region) — is standard practice in pediatric hematology programs.
Despite the procedure's clinical importance, research on effective teaching methods is limited, and trainees historically learn by observation followed by supervised attempts (Yamamoto et al., 2025). A dedicated task trainer closes this gap: it lets learners repeat the full puncture sequence until the motor skill is established — before they ever touch a patient.
2. Evidence: Simulation Models Teach Invasive Procedures Safely
Evidence | Finding | Implication |
Yap et al., 2015 (Simulation in Healthcare) | BMAT is common in hematology-oncology; complications can cause significant morbidity; simulation models are the appropriate training route | A bone marrow simulator is the standard-of-care training tool, not an optional extra |
Yamamoto et al., 2025 (Internal Medicine) | Researchers developed a novel BMAT simulator because effective teaching methods were lacking; simulation-based BMAT education was delivered to medical students | Structured simulator training is an emerging educational standard |
AlShammari et al., 2018 (J Pak Med Assoc) | A pediatric simulation course in procedural skills improved pediatric residents' confidence and skills | Simulation transfers to pediatric procedural competence |
Fleming et al., 2020 (J Am Coll Radiol) | Physical 3D models significantly raised anatomy exam performance in medical students (P<0.0001) | Physical, tactile models outperform 2D teaching for landmark-heavy skills |
Cook et al., 2011 (JAMA) | Technology-enhanced simulation yields large learning gains (effect sizes 1.09–1.20; 35,226 learners) | Hands-on simulation is among the most effective teaching methods |
The FS6 is the pediatric-leg complement to this evidence: a low-cost, repeatable physical trainer for a procedure that is otherwise learned on patients.
3. What the FS6 Trains: The Pediatric BMA Sequence
Step | Skill Trained | FS6 Feature Supporting It |
1. Site localization | Palpate and identify the correct puncture site on the child's leg | Obvious superficial bony landmarks on the simulated left leg |
2. Positioning & stabilization | Hold the limb firmly; control the approach angle | Life-like child-leg geometry |
3. Needle advancement | Apply controlled force through skin, periosteum and cortex | True puncture resistance on entry |
4. Aspiration | Withdraw the stylet; aspirate marrow | Simulated marrow fluid is obtained on a successful puncture |
5. Confirmation & aftercare | Verify sample, withdraw needle, apply pressure | Fluid feedback confirms correct technique in real time |
What makes it a good assessment tool
Objective success signal
● — simulated marrow fluid appears only when the puncture is performed correctly, giving instructors an unambiguous pass/fail criterion.
Repeatability
● — the same landmark and resistance profile every attempt, so students can build muscle memory through deliberate practice.
No patient risk
● — errors (wrong site, excessive force, incorrect angle) are corrected on the model, where they are free.
4. Where the FS6 Sits in the BIX F-Series
Model | Focus | Role in a Pediatric Skills Lab |
BIX-FT534 | Five-year-old full-body simulator (care, CPR, airway, BMA module) | Integrated multi-skill pediatric patient simulator |
BIX-FT337 / FT334 | Baby / five-year-old CPR & nursing simulators | CPR + nursing rotations |
BIX-FT2 / FT41 | Newborn nursing dolls | Basic newborn care |
BIX-FS6 | Child leg bone marrow puncture (dedicated) | Standalone BMA training & assessment station |
BIX-FS | Gynecological examination model | GYN skills |
Buying logic: programs that need full pediatric simulation choose FT534 (which includes a bone marrow aspiration module among many others); programs that need dedicated, repeatable BMA practice and assessment at the lowest cost add the FS6 — one trainer can serve an entire pediatric hematology rotation.
5. Teaching Protocols
Station A: Landmark Identification — 15 min
1. Students palpate the FS6 leg and mark the puncture site using the bony landmarks.
2. Instructor verifies against an anatomical reference before anyone advances the needle.
Station B: Full BMA Sequence — 10 min per attempt
1. Set up: position leg, select site.
2. Advance needle through skin and cortex; feel the resistance change.
3. Aspirate and confirm simulated marrow fluid.
4. Withdraw and apply post-procedure pressure.
Station C: Assessment — checklist grading
Criterion | Pass |
Correct site identified from landmarks | Yes / No |
Appropriate angle and stabilization | Yes / No |
Controlled advancement (no over-force) | Yes / No |
Marrow fluid obtained on first/second attempt | Yes / No |
Correct post-puncture handling | Yes / No |
Station D: Refresher cycles
Bone marrow aspiration is a low-frequency skill in most rotations — schedule refresher drills each term so the sequence stays automatic (AlShammari et al., 2018).
6. Maintenance
Item | Frequency | Notes |
Puncture site | After each session | Simulated skin self-seals or is replaceable — check spec sheet |
Simulated marrow fluid | Refill as consumed | Training fluid only; order refills from manufacturer |
Surface cleaning | After each use | Wipe with standard disinfectant |
Storage | Always | Keep in the supplied packaging when not in use |
7. FAQ
Q1: Where is the puncture site on this model? A: The FS6 is a simulated child left leg with obvious superficial bony landmarks that guide learners to the correct pediatric puncture site. The site-localization step is itself part of the trained skill — instructors verify landmarking before needling.
Q2: How do we know a student performed the puncture correctly? A: The model gives an objective success signal: a correctly performed puncture yields simulated bone marrow fluid. This makes the FS6 usable for pass/fail skills assessment, not just practice.
Q3: How is the FS6 different from the FT534 five-year-old simulator? A: FT534 is a full-body pediatric simulator with a bone marrow aspiration module among many functions (care, CPR, airway, injections). The FS6 is a dedicated child-leg bone marrow puncture trainer — lower cost, purpose-built for repeated BMA practice and assessment stations. Large programs typically own both: FT534 for integrated scenarios, FS6 for deliberate BMA practice.
Q4: Is this model suitable for hematology fellowship or only nursing school? A: Both. Medical students, pediatric residents, hematology-oncology trainees, and nurses who assist BMA procedures all need the same motor sequence. The FS6 is used wherever the procedure is taught.
Q5: What is the MOQ and are evaluation units available? A: MOQ is 1 unit; evaluation samples can be arranged for institutional review. Email chinonplus@adaanatomy.com for a quotation and the specification sheet.
Q6: What is the price and delivery time? A: Reference price is USD 427.18. Air freight: 7–10 business days; sea freight: 30–45 days. Email chinonplus@adaanatomy.com for the current quote.
