IMPORTANT SAFETY INFORMATION

1. Please ensure the voltage on the label of the plug corresponds to the voltage of the electricity supply. The device must be powered by a differential switch which has a nominal current equal to or lower than 30mA
2. The plug must not be switched on until after the fluid system has been set-up (please refer to page 5) to avoid inflicting damage to internal fluid system
3. Please ensure there is no damage to the plug or the cable before connecting to the mains power
4. The internal pump which circulates fluid throughout the model has a USB A to USB C Cable.
5. ATTENTION: Ensure to disconnect all submersed electrical products before doing any maintenance to any appliance in the water or dipping the hand in the water. If the plug or the electric outlet is wet, disconnect the general switch before disconnecting the electric supply cable
6. The product can be used in appropriate liquids with a temperature not higher than 35 degrees or 95 degrees Fahrenheit
7. Avoid using the product with corrosive and abrasive liquids
8. Do not use the product for uses different to those for which it has been designed for
9. The product has not been designed for people with disabilities and/or children if they are not supervised by a person responsible for their safety
10. The fluid system pump arrives submerged in the encased box. The internal pump is not to be removed and TruCorp take no responsibility for any damage caused by anybody that removes it unwilfully

The TruNerve Block is ideal for training a range of techniques including:

Nerve Bundle

• 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 TruCorp’s’ 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.
• When 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

IV

• High frequency linear array ultrasound probe can be used on the model
• Colour Doppler detection of blood flow
• Realistic flashback upon entry into the vessel
• Two embedded vessels, small/large and shallow/deep
• Real feel vascular tenting’ upon entry into the vessel · Self-healingTruUltra’ material that leaves minimal marks and self-regeneration

Bone

• An acoustic shadow artifact in the hypoechoic region deep to a hyperechoic bone outline
• Fracture assessment detection of a fracture and diagnosing bone stress

IV vessels

Nerve Block Use ­ It’s vital that the Nerve Block part of the model is only used to administer `artificial’ anaesthesia around the nerve. The vein and artery beside the nerve is only for visual use and should not be penetrated with a needle. Any damage occurred here will not validate a warranty replacement.

Bone Fracture

BEFORE YOU BEGIN

• Ensure the model is placed on a dry and flat surface
• Fill up the blood reservoir by using the blood concentrate to the levels needed (instructions on the bottle)
• Insert 6 AA batteries into the battery holder or connect the USB cable
• Spray generous amounts of ultrasound gel on the product to ensure good probe imagery
• Ensure your Ultrasound machine is placed close by to the product
• You are now ready to use the mode

INITIAL SET-UP:

1. The product comes ready to use for Nerve Block training (the TruUltra gel is prefilled). This procedure can be practised without power.

2. For IV use, you need to prepare the mock blood (approx.200ml to fill the blood reservoir container to the maximum level) and pour the blood into the black base using input labelled blood in.

3. Turn on the product using the push button switch.

For initial set-up please wait a few minutes to allow the product to fill the blood completely. If the ultrasound image is not clear for IV, compress the insert and try again.

Compressing:

REPLACING THE INSERT

1. To replace the insert, turn off the pump and remove the fluids.

2. To remove the insert gently bend and lift the insert, disconnect from the `gel in’ side first.

3. Disconnect all connectors.

4. Repeat the procedure on the other side, please note some blood spillage may occur.

5. Take the new insert and attach it to the connectors on the base, connect the “gel out” side first. When connecting, always connect the black connector first, then repeat the process until all connectors are secure.

6. Slide the insert back in place on the base.

7. Repeat the process on the second side.

8. The product is ready to re-use.

9. The insert has been designed for a single connection only, please do not connect/ disconnect unnecessarily.

REPLACING THE TRUULTRA GEL

1. To replace the TruUltra gel inside the insert you will need: 2x 20ml luer lock syringes with the luer lock adaptors connected, black tubes and the TruUltra gel.
2. The gel will need replaced when approximately 20 ml of fluid has been introduced into the nerve area.
3. Connect the empty syringe to the `gel out’ connector and extract approx. 20ml of fluid. If there you are unable to extract the gel, use an ultrasound probe to gently guide the gel to the area in a leftwards motion.
4. Introduce approx. 5-7 ml of new TruUltra gel using the syringe, to the area labelled `gel in’.

When connecting the black tube to the base, a click will indicate secure connection. To disconnect the black tube push down the base connector around the tube and pull out the black tube.

REMOVING FLUIDS

To remove the fluids, turn off the product.

Hold the base above the empty container and remove the black silicone cap and wait for all the liquid to drain out. Please do not turn the model upside down to remove the fluids as this may affect the internal power system.

CARE AND MAINTENANCE

Store the product in clean, dry conditions away from heat and direct sunlight; avoid contact with metals, solvents, oils or greases and strong detergents. When the product is not in use, please store in the black carrier case provided.
Gently wash the ultrasound insert after use. Please use alcohol wipes, warm soapy water or similar, until all visible foreign matter and residue are removed.
