levels (greater, in absolute value, than 250 mmHg (33.3 kPa)), thus preventing the possibility of
implosion.
The reservoir is available in two versions, TOP outlet and BOTTOM outlet, differing only in the location
of the outlet port connection to the Bowl set (see Figure 3-27):
• In the TOP outlet version, the outlet port connection to the Bowl set is located at the top of the
reservoir.
• In the BOTTOM outlet version, the outlet port connection to the Bowl set is located at the base of
the reservoir through a 1/4 inch outlet adapter.

Aspiration Line
The Aspiration Line (see Figure 3-28) consists of clear plastic (PVC) dual lumen tubing.
The proximal end of the large bore tube is designed to be attached to a 1/4” inlet port on the X
TRA
blood collection reservoir. The proximal end of the smaller bore tubing is connected to the
anticoagulant solution bag/bottle via a spike connector.
The smaller lumen tubing has a roller clamp which controls the flow of the anticoagulant solution. The
anticoagulant solution is pulled through the smaller bore lumen toward the field by suction acting
through the reservoir and the larger bore lumen.
The distal ends of both lumens terminate in an aspiration connector with a diameter of 1/4 inch that
connects to most suction cannulae.
In the aspiration connector, anticoagulant solution mixes with the aspirated blood as the blood passes
the point where the two lumens join together. This allows the aspirated blood to be anticoagulated
after only a short exposure to the cannulae.
The vacuum then draws the anticoagulated blood into the blood collection reservoir.
