1-3.2. External Features - Right Side View
The external features in Figure (1-2.) of the BLANKETROL II unit are described as follows:
A.
The water flow indicator is a paddle wheel immersed in the path of the circulating
water with a window to the outside. As water is circulated through the system, it
passes over the paddle wheel causing it to spin (like a pinwheel). The water flow
indicator provides a visual display of the general rate at which the water is circulating.
For example, if the unit is circulating water but the connecting hose is pinched, the
circulation of the water is restricted. The restriction in water flow decreases the speed
of the paddle wheel.
The water flow indicator only spins when a blanket or by-pass hose is connected to the
unit. It will not spin while the water is being circulated internally to pre-condition the
water to the ‘preset” water temperature chosen by the operator.
A total obstruction of the water path will cause the paddle wheel to stop completely.
B.
The air vents, on both the right and left side of the unit, provide air circulation for the
microprocessor.
C.
The four capped screws on the right and left side of the unit secure the top to the base.
D.
The patient 1/4 inch receptacle is where the 400 Series probe (refer to Figure 6-9 for a
list of temperature probes) is connected to the unit. Only one patient probe can be
connected at a time.
E.
Three female, quick-disconnect return fittings on the top row are designed for water to
flow in when the male coupling of the connecting hose is attached.
F.
The three male quick-disconnect outlet fittings on the bottom row are designed for
water to flow out when the female coupling of the connecting hose is attached.
G.
The power cord with a hospital-grade plug should only be plugged into a properly
grounded hospital grade receptacle. Electrical Specifications are described in Section
(7.).
H. The isolation label indicates that the BLANKETROL II and the blanket (applied part)
are BF rated as a system. Contact with other parts (i.e. the quick-disconnect fittings) at
the same time as contacting the patient will negate the type BF rating.
