Using the CapiScope HVCS

CapiScope Probe Cover

image1

The Probe Cover is the APPLIED PART, a precision-manufactured disposable that fits over the probe. The closed end of this cover is a precision optical window. This provides protection for the probe objective and also electrical and biohazard protection for the patient.

The Probe Cover is a single-use disposable accessory. Do not reuse it. Dispose of each used Probe Cover in biohazard containers.

Do not use the CapiScope HVCS without a Probe Cover.

Do not touch the patient whilst changing a Probe Cover.

Replace the probe cover with a new one.

Remove the old probe by pulling straight down.

Push on the new probe cover.

Make sure the cover pushes fully into the clip. The top of the probe cover should reach the top of the slots in the clip.

When you’ve finished using the CapiScope HCVS always put a Probe Cover on to protect the lens.

Using the Focus Ring

The CapiScope HVCS has a fixed focal plane about 3.5 millimeters beyond the probe tip.

Turning the focus ring moves the probe cover closer or further away.

Looking from the top, turn the focus ring clockwise to focus deeper into the tissue. Turn anticlockwise to focus closer to the surface.

The focus ring is spring loaded to minimise hysteresis when adjusting the focus ring. When in focus it should be possible to pull the focus ring upwards towards the device body by 1 to 2 mm. When the focus ring is released, it should spring back into the focus position.

When the focus is adjusted to the deepest level into the tissue (i.e. the focus ring is wound fully clockwise when looking from the top), it will then not be possible to pull up against the spring.

When first using the CapiScope HVCS, turn the focus ring anticlockwise fully, then turn clockwise about one turn until the tissue surface is in focus. Turn a little more to focus on the capillaries below the surface.

One turn = one millimeter.
