CVI Scanning Accessory
The Simple UpCL is a patient lift platform that was originally developed to assist patients and Radiographers when taking weight bearing x-rays of the hips, knees, feet and ankles. The system particularly benefits the Radiographer, improving their working ergonomics.
The CVI accessory for the Simple UpCL has been specifically developed to assist Vascular Scientists and Sonographers with duplex ultrasound imaging of lower extremity veins when conducted on standing patients.
Duplex ultrasound imaging of lower extremity vessels can present difficulties for both the clinician and patient particularly when the patient has limited mobility and is unable to or has difficulty standing for long periods.
A survey conducted by the SVT – professional standards committee in 2012 reported that:
- The average number of patients seen per day by an experienced scientist is 11.9
- Lower limb scans (combined) constitute the second highest scan performed after Carotid.
- The time taken to conduct a lower limb Duplex scan can range from 24 to 60 minutes
The flexible seat and sturdy hand rails provide support for the patient during the lengthy examination and the height adjustment of the platform improves the working ergonomics for the vascular scientist or sonographer.
It is recommended that the ‘gold standard’ for the evaluation of the superficial venus system is with the patient standing as opposed to the Reverse Trendelenburg position or supine:

The Society for Vascular Technology state that when the patient is scanned standing up, a raised platform/step with patient support may be useful.
