BIX-L68B Central Vein Puncture Model: How to Run a CVC Insertion Class

Short answer: BIX-L68B is a neck-region trainer for central venous catheterisation. The cervical veins are filled with red simulated blood for internal jugular and subclavian vein puncture, a squeeze bulb reproduces the carotid pulse, and the skin and internal tubing are replaceable. Its distinguishing claim is anatomical fidelity in the landmarks — the supplier states that palpation is "exactly the same as on a patient" — which is what makes it a worthwhile first station before supervised human practice.

Key takeaways

• Two access routes, one model: internal jugular vein and subclavian vein puncture and cannulation are both supported.
• Palpable landmarks are the point. Sternal notch, clavicle, right cervical ribs and sternocleidomastoid are stated as clearly indicated.
• The carotid pulse is simulated by a squeeze bulb — so the student must distinguish artery from vein by feel, not by colour.
• Wear parts are replaceable. The page states the internal tubing and skin are easy to replace.
• Package size and price are not published on the page; both must come back in writing.

What the model provides, as published

Published item	Teaching value
Cervical veins filled with red simulated blood	Gives a visible return on successful venepuncture, so the student knows they are in the lumen.
Squeeze bulb simulating carotid artery pulse	Trains artery-versus-vein discrimination by palpation before the needle moves.
Accurate anatomy; palpation stated to be the same as on a patient	Transfers landmark drill from model to patient more credibly than a featureless block.
Easy replacement of internal tubing and skin	Keeps a class running after repeated punctures instead of retiring the unit.

The seven published features

Published feature	What it means in a lesson
Cervical landmarks clearly indicated: sternal notch, clavicle, right cervical ribs, sternocleidomastoid	The student names each landmark aloud before touching a needle.
Left-neck deep venous system: common carotid artery, internal jugular vein, external jugular vein, subclavian vein, brachiocephalic vein	Gives the full venous context, not just the target vessel.
Internal jugular vein puncture and cannulation	Primary route, practised to cannulation rather than puncture alone.
Subclavian vein puncture and cannulation	Second route, with a different landmark logic.
Carotid artery pulse simulated	The safety-critical skill: not hitting the artery.
Intubation of Swan-Ganz catheters	Extends the drill from access to catheter passage.
Skin and veins replaceable, with an apparent feel when the needle enters the vein	Repeat practice plus tactile confirmation of entry.

How to run the class: a six-step sequence

1. Landmarks before needles. Every student must locate and name the sternal notch, clavicle, sternocleidomastoid and the cervical ribs. Nothing is opened until this is fluent.
2. Find the pulse first. Use the squeeze bulb so the carotid pulse is running. Students should identify the artery by palpation alone — the model's red fluid belongs to the veins, and the artery must be avoided by feel, as in practice.
3. Route one: internal jugular vein. Puncture, aspirate, then cannulate. Check that simulated blood returns and that the student can explain why the position is safe.
4. Route two: subclavian vein. Repeat the whole sequence. The landmark logic differs, and it is the step where students most often drift.
5. Add catheter passage. The page lists Swan-Ganz catheter intubation, so advance from access to catheter handling in the same session.
6. Debrief on the artery. The most useful question is not "did you get in" but "how did you know you were not in the carotid".

Why simulation is the right place to learn this

Central venous access training has been an active field precisely because the procedure carries risk and because trainee exposure is uneven. A 2026 paper describes the design of a dedicated insertion training system for central venous catheterisation [1], and a separate 2026 study presents a cost-effective model built for high task alignment in ultrasound-guided central venous catheterisation training [2]. A qualitative study of physician experiences identifies the barriers that stop trainees getting adequate central line training in the first place [3] — which is the operational reason a bench model earns its place: it moves the first hundred attempts off the patient and onto a unit that can be reset.

The honest limit: the page does not state ultrasound compatibility. If your programme teaches ultrasound-guided CVC, confirm that with the supplier before ordering, because it materially changes the exercise.

FAQ

Q1. What is BIX-L68B?
A central vein puncture and cannula model for practising internal jugular and subclavian vein access, with simulated blood return and a simulated carotid pulse.

Q2. Which access routes can be practised?
Internal jugular vein puncture and cannulation, and subclavian vein puncture and cannulation. Swan-Ganz catheter intubation is also listed.

Q3. How does the model show that the needle is in the vein?
The cervical veins are filled with red simulated blood, so return is visible; the page also states there is an apparent feel when the needle enters the vein.

Q4. Can students practise avoiding the carotid artery?
Yes — a squeeze bulb simulates the carotid pulse, so the artery can be identified by palpation and avoided.

Q5. Are the wear parts replaceable?
Yes. The page states the internal tubing and skin are extremely easy to replace.

Q6. What is not published?
Package size and price. The page's "Package size" field is blank. Email chinoncpr@adaanatomy.com with the model (BIX-L68B) and your quantity for the unit price, carton data, ultrasound compatibility status and the spare-part list.

Request a quotation

Write to chinoncpr@adaanatomy.com for the BIX-L68B specification sheet and a quotation. If you are fitting out a procedure room, ask in the same enquiry about the replacement skins and tubing in the quantity you will actually consume per intake — the consumable line, not the unit price, is what determines the annual cost of a puncture trainer.
