IR System - Troubleshooting

Common Mistake


The shoulder joint screw is not adjusted for the correct approach, consequently meaning the STARBoard either moves too freely and swings out or is too firm and cannot be easily manoeuvred.

The tension of this screw is adjusted to different settings depending on what arm approach you're doing. When you do a left arm approach you need it free to pivot when carrying out puncture. Then when you attach Left arm support you would then tighten the shoulder screw to prevent left arm support from pivoting away from the patient.

If the wrist pivot screw is not adjusted, rotation of the STARBoard handle for hyper extension can be difficult. If it is too tight, it is difficult to rotate and flex the handle downwards. If it is too loose, the handle will move too freely.

The wrist pivot screw needs to be adjusted for ease of manoeuvrability when adjusting the STARBoard handle for hyper extension of the wrist. If the wrist pivot is too loose, the handle will move too freely and if it is too tight, it will be difficult to adjust the handle.

If the STARBoard is placed on the lab table incorrectly, it greatly affects other components of the STARSystem and patient set up.


Correct table placement of the daggerboard is essential to the function of the STARSystem.

The daggerboard should be positioned between the shoulder and the elbow. Optimum placement is dependent on the height of the patient.

Taller Patient Placement

The optimal position for taller patients is between the shoulder and mid-arm, often closer to the shoulder.

Shorter Patient Placement

The optimal position for shorter patients is between the mid-arm and elbow, often closer to the elbow. 

If the slider arm is not adjusted once the patient has been positioned in the arm rest, it will cause discomfort for the patient and make hyper-extension difficult.

Adjust the slider arm to suit the individual patient once they have been positioned in the arm rest. The patient should not be strained to reach the handle and should have a comfortable grip.


Ensure the daggerbaord is correctly positioned in relation to the height of the patient and that the armrest has movement available on the slider arm.

Hyper-extension is attempted without correctly placing the patient’s wrist in and turning it. This makes hyper-extension difficult to complete and causes patient discomfort.

Complete the correct steps to achieve hyper-extension by getting the patient to grip the STARBoard handle before rotating and hyper-extending the patient’s wrist for hyper-extension.

The daggerboard is not pushed fully underneath the mattress, causing product instability.

To ensure product security throughout the procedure, push the daggerboard fully underneath the mattress, so the IR Shield slot is firmly against the mattress.

The IR Shield is not placed centred within the slot, causing weight imbalance and the product to fall out.

Do not slide the IR shield too far either side of the arm support. This will cause a weight imbalance and the shield will fall off.

The Extension Tray is not fully clipped on, causing instability during the procedure

Ensure the extension tray is fully clipped on and stable before draping the patient. This will ensure complete stability during the procedure
