FAQ

Use gel and increase the gain to the maximum to visualize the anatomical structures, then dial back the gain as necessary. Switching to a vascular preset and turning off tissue harmonics will also improve the image.

25 Gauge is recommended for longer life but no larger than 22 gauge

No. Most users prefer to utilize needles currently used in their practice.

There is no standard answer since it depends on the user and procedure but the following have an impact on simulator life:

• Needles size used - 22G or smaller is best. Never use a Touhy tipped needle.

• How the needle is manipulated during placement- aggressive redirection should be avoided

Valkyrie simulators have been used in monthly is numerous training programs worldwide for more than 3 years without replacement!

• Track marks are formed when a needle is passed through the simulator creating a micro channel or fissure in the material

• The channel fills with air as the needle is withdrawn

• Oil within the material will fill the track and push the air out. As the air dissipates, the track mark fades

Hint:

Purchase an additional insert to change out for busy training programs. This will allow one to “heal” while the other is in use.

Usually within days depending on size of the track

Storing the product in a warm environment can sometime help depending on the size of the track mark. However, avoid directly heating the simulator as this may lead to deformation and permanent damage.

Hint:

Use small gauge needles

Since in person product training is not always possible, we have developed a series of videos and simple pictorial instructions for use (IFU) which are included with your system.

The IFU contains instructions for care and use including the scanned target.

Yes, with the understanding that

1. Larger needles must be used to assist catheter placement which results in larger track marks and shorter simulator life

2. Large track marks take longer to heal and can cause permanent damage

3. Advancement of the catheter will require more force than is typical with human tissue

Hint:

Order a rotation insert to have an additional insert while allowing time for your insert to “heal” from the use of the larger needles and catheters.

Each simulator will contain all of the typical landmarks associated with the specific block.

Refer to the catalog for a listing of internal and external landmarks for each model.

Typical landmarks include vessel, nerve(s). bone, fascial planes and muscle.

Except for Vascular access models MINISIM Simulators have solid vessels to avoid permanent puncture damage that causes fluid leakage.

Only Vascular Access vessels require filling.

Hint:

1. Remove the insert

2. Remove the plugs for the vessels

3. Using an air purged syringe, filled with clean sterile water, fill the vessels until the bubble at the top

4. Replace the plugs

5. When finished drain the vessels

6. Tip: Add a small amount of alcohol to water to reduce the likelihood of bacterial or fungal growth

Keep in a dry room at room temperature.

Hint:

If in a cold region, make sure your Simulator is above 10° C for optimal visualization.

Because simulators do not contain fluid like the human body, you should adjust the Gain for optimal image.

Hint:

In most cases gain should be increased. If your Ultrasound has THI (Tissue Harmonics Imaging), disable while scanning a simulator. Using a vascular presets often produces the best image.

Gel is recommended for ease of use and optimal image.

Hint:

Use small amounts and clean before storing

Clean with a damp and soapy cloth or alcohol wipes.

Hint:

Clean before placing back in storage

Acoustic shadowing on an ultrasound image is characterized by a signal void behind structures that strongly absorb or reflect ultrasonic waves. This happens most frequently with solid structures, as sound conducts most rapidly in areas where molecules are closely packed, such as in bone.

When the ultrasound beam reflects back and forth between the reflectors ("reverberates"), the ultrasound transducer interprets the sound waves returning as deeper structures since it took longer for the wave to return to the transducer.

Hint

Reverberation artifacts can be improved by changing the angle of insonation so that reverberation between strong parallel reflectors cannot occur.

The needle must be properly aligned with the probe in order to visualize the needle or needle tip.

For in-plane the needle must be parallel to and directly under the centre of the probe.

For out-of-plane the tip will only become visible once it has passed through the ultrasound beam. Additional small movement of the probe away from the needle shaft will allow the tip to be tracked as it move deeper. A common error is to keep the probe stationary and advance the needle without tip confirmation resulting in erroneous observation of the shaft in the belief that it is the tip.

Hint

Realignment the probe to the needle, not the needle to the probe. Probe alignment movement should be very small and typically will not result in the required anatomical image being lost.

You can inject into the simulator fluid around the nerve but because the nerve is a solid structure, you will encounter high pressure just as you would expect in a human. In this case you can determine if your needle is within the nerve.

Hint

Withdraw before injecting just as you would in a patient.

You can thread a catheter, but this usually means the use of an 18g needle which will decrease the life of your simulator insert.

Hint

Purchase an additional insert if you are going to use large needles. It will require much longer for track mark to dissipate. A busy training program can require insert change.

1. Small gauge needle (23 or 22g)

2. Ultrasound

3. Standard ultrasound gel

4. Water and alcohol if it is a Vascular Access model

5. Wipes or cloth for cleaning (hand wipes work fine)

6. Epidural needle and LOR syringe for Epidural model (catheter can also be used)

Hint

Smaller gauge needles increase life.

A bubble or bubbles might form under the surface to indicate damage from fluid injections. Simulators are cast with layers of material to resemble human anatomy. These layers can separate over time from repeated bolus injections.

It is important to follow injection instructions for longer life.
