The pump head features are shown in Figure 2.
Pump Head Features
ITEM
FUNCTION
1. Upstream occlusion sensor
Detects a complete tubing restriction up-
stream of the pump.
2. Pumping fingers
The linear peristaltic pump mechanism con-
sists of cam-driven pumping fingers which
successively manipulate the tubing against
the backplate, resulting in fluid movement in
a downward direction.
3. Downstream occlusion
sensor
Detects tubing restrictions downstream of the
pump. The sensitivity level can be adjusted to
suit the needs of the hospital through the
pump's configuration.
4. Air sensor
Detects air bubbles in the tubing. The sensi-
tivity is adjustable via the pump's configura-
tion.
5. Safety clamp
Prevents accidental fluid flow by automati-
cally occluding the tubing whenever the pump
door is opened.
6. Slide clamp slot
When the slide clamp loading option is en-
abled, the I.V. set's slide clamp must be in-
serted into this slot. The operator must push
the slide clamp into the slot to occlude the
tubing before the I.V. set can be removed from
the pump. The slide clamp loading option is
selectable through the configuration.
7. Slide clamp spring retainer
If your hospital has not selected the slide
clamp loading option, this spring retainer will
be inserted into the slide clamp slot, prevent-
ing the insertion of the slide clamp into the
slot.
