Regional Anesthesia Ultrasound Training Block Model
TruNerveBlock is a 3-in-1 model for trainee anesthetists to develop, practice and maintain the skills necessary to use ultrasound for guiding regional anesthesia and vascular access procedures. The model features a fractured bone structure & embedded vessels allowing effective practice of routine IV cannulation and additional nerve bundles for regional anaesthesia.
This model is ideal for emergency medicine, radiology, surgical training programs, ultrasound training programs, simulation centers, surgical skills centers, medical education facilities, and ultrasound manufacturers for ultrasound education and demonstrations.

Regional Anesthesia Ultrasound Training Block Model
Why choose this model?
Self-healing TruUltra material is good for over 1000 nerve block needle insertions.
3 in 1 model! Ours is the only nerve block trainer on the market to have 3 features in 1 product: IV cannulation of multiple veins, regional anaesthesia practicing around the nerve, and bone fracture identification.
It’s durable! TruNerve Block comfortably facilitates the insertion of over 1000 nerve block needles. The self-healing and regenerative TruUltra material has been designed to withstand repeated use. If left overnight, TruUltra regenerates up to 90%.
It’s realistic! The product has clearly defined fascia layers, veins, arteries, nerve, bone and allows colour Doppler visualisation. A unique, fully-integrated fluid management system replicates realistic blood flow in an adult and gives positive flashback upon needle entry.
No mess! Quick blood refill mechanism and snap-fit fluid connectors allow quick & easy insert replacement. Our unique design means no leaks occur.
Features our exclusive self-healing TruUltra material and ultrasound gel
Delivered ready to use in durable carry case for easy transportation and safe storage
Practice probe positioning and movement, recognition of arterial and vein vessels and nerves in soft responsive tissue. Using ultrasound to target the vessels and nerves for ultrasound guided regional anaesthesia and vascular access procedures.
Surrounding vessels are used as reference points to differentiate from the nerve
Simulated anaesthetics can be injected into the model with visual air and fluid retention possible alongside the nerve
Ability to verify needle tip location and to practice the entire regional anaesthesia procedure
Fluids can be easily removed from the product through our self-contained innovative fluid management system so that the product can be used repeatedly for training
Using TruCorps’ unique ultrasound gel this creates a perfect medium to allow fluid retention and realistic muscle fluid absorption
This ultrasound gel can be removed upon fluid build-up easily with a syringe and new gel inserted easily
Once users accurately access the vessels within the model, positive fluid flow provides the user with positive feedback that they have cannulated the targeted vessel
Visualizing of the artery and vein laterally beside the nerve
High frequency linear array ultrasound probe can be used on the model
Snap-fit fluid connectors & quick blood refill mean faster training & no mess.
Two embedded vessels, small/large and shallow/deep
Real feel vascular ‘tenting’ upon entry into the vessel
Self-healing TruUltra material that leaves minimal marks and self-regeneration up to 90% within 24 hours
We recommend the following needle equipment sizes for optimal performance:
IV: 21G needle
Nerve block: 21G needle
Bone fracture identification
An acoustic shadow artefact in the hypoechoic region deep to a hyperechoic bone outline
Fracture assessment detection and diagnosing bone stress injury
TruNerve Block FAQ
Question: Does the nerve block always need to be turned on and plugged into the mains to work?
Answer: No. The product can be turned on for a few minutes to allow time for the blood to work through the veins and it can then be unplugged and used.
Please note: If a needle is used to withdraw blood then the pump will need to be turned on again to refill the veins. If no blood is withdrawn then visually the product can be used.
Question: How many times will the nerve section of the product allow needle incisions and how much fluid to insert?
Answer: The nerve section will allow up to 1000 incisions based on the correct needle gauge (21G). The insert will continuously allow insertion of up to 20ml of ‘anaesthesia’ before this will need to be replaced.
Question: How much TruUltra gel should I put into the product when refilling?
Answer: Insert approx. 5-7ml of TruUltra gel into the ‘Gel in’ connector.
Question: What flow speed is the pump?
Answer: The flow speed closely resembles a normal adult at approx. 6.5L/min.
Question: Is there any latex in the product?
Answer: No latex is in the product. It is made up of our unique TruUltra material, plastic and silicone parts.
Question: How many times will the IV section of the product allow needle incisions and will they be seen?
Answer: As seen below some needle tracks will be seen initially the more the product is used, however if allowed to rest for 24h, up to 90% material recovery is seen. The product has been tested for over 1000 incisions without fail.
Ultrasound guided IV tips
IV cannulation is a common procedure, usually accomplished quickly and without problems. In cases where intravenous access is complicated (by obesity, IV drug abuse or edema for example), using an ultrasound to gain vascular access can be an effective solution.
Tips for practicing ultrasound-guided IV placement:
Be ready with all the supplies you need at hand, and extras within arm’s reach.
Position the patient and the ultrasound machine correctly. Make sure the patient is comfortable and that the machine is on the opposite side of the arm (or training model) being used, angled so you have an unobstructed view of the screen.
Practice both short axis and long axis approaches to become familiar with both longitudinal and transverse views of blood vessels and tissue.
Be aware of compressing soft tissues and veins with the ultrasound probe. The depth of a blood vessel can appear different when pressure is applied.
If necessary, flush the line with saline after placement to verify integrity. You should see turbulence inside the vein if it’s placed correctly (and leakage into the surrounding tissues with insertion failure).
