3. Functional Description

This chapter describes how Qseal-extra works, where the connectors and the indi-
cations are placed on the unit and their functions.

3.1 Description of Sealing

The indication for use of Qseal-extra is a need for seal and separation of tubing or bags
in blood component sets during blood and plasma donation or other blood component
preparation. The target population is determined by the intention of the blood compo-
nents as determined by the trained medical professionals operating the device. The use
of Qseal-extra does not limit the initial target population or intended use of the blood
components.
The tube to be sealed is placed in the slot of the Hand unit, between the electrodes.
When the user presses the trigger, the sealing procedure will commence automatically.
When the tube is pressed together, the radio-frequency (RF)-generator starts. The
energy is transferred from the sealing electrodes to the tube, which melts to a sterilized
welding pattern.
A built-in lamp in the Hand unit lights during the sealing. The intelligent sense control
board in the Main unit detects, controls and adjusts the sealing activity which gives the
best sealing quality for the type of tubes that are being used.

3.2 Description of Equipment

The Sealer equipment consists of one Main unit, including Battery unit, one Hand unit
and Battery charger. The Coaxial cable is used to connect both units. Below is a short
description of each component.
The Coaxial cable is a special shielded coaxial cable, which transfers the RF-energy, the
control signal and the air pressure, between the Main- and the Hand-unit.
