8. FLOW SETTING control buttons (Figure 16) sets the

maximum flow that is desired by the surgeon. This value

is indicated on the FLOW SETTING display.

9. FLOW READING (Figure 16) is registering the amount

of gas and vapor that is actually flowing at the present

time. This value should be zero, when the vacuum pump

is not turned on.

10. CHANGE FILTER indicator is located above filter (Fig.

17). It illuminates when there is a reduced flow into the

CRYSTAL VISION

Hydrophobic ULPA Filter with Built-in Fluid Trap

should be changed when this light first illuminates. Do

not attempt to clean, or re-use the SAFEGUARD

BLUE

Hydrophobic ULPA Filter with Built-in Fluid

Trap.

according to your institution's biological waste protocol.

This indicator will also come ON when there is a total

occlusion. If the OCCLUSION indicator is also lit, be

sure to clear the obstruction that caused it first and then

check the CHANGE FILTER indicator. If it is still

illuminated and the OCCLUSION indicator is not, then

the SAFEGUARD BLUE

with Built-in Fluid Trap needs to be changed.

11. OCCLUSION indicates that flow into the CRYSTAL

VISION

has stopped (Figure 17). The CHANGE

FILTER light will also come ON at this time. The

operator should check for kinked tubing, stopcocks that

are turned OFF, clogged insufflator, use by date of Large

Coconut Charcoal Output Filter, or a completely clogged

SAFEGUARD BLUE

Built-in Fluid Trap. In order to prevent pump failure, the

CRYSTAL VISION

lamp is illuminated.

12. OVER PRESSURE indicates pressure exceeding 27

mmHg in the pneumoperitoneum (Figure 17). At

pressures over 30 mmHg, the vacuum pump starts in order

to reduce the pressure in the pneumoperitoneum. This

situation can be caused by many factors. Frequently, the

surgeon presses on the abdomen and this causes intra-

abdominal pressure to rise. Correct the cause before

continuing.

13. The "NO PATIENT" indicator (Figure 17) turns on when

the CRYSTAL VISION® is in the LAP MODE, when

zero pressure, or atmospheric pressure, is present at the

SAFEGUARD BLUE

Built-in Fluid Trap. The tubing set may not be connected

to the Trocar sheath or to the SAFEGUARD BLUE

Hydrophobic ULPA Filter with Built-in Fluid Trap; the

valve on the Trocar sheath may be turned off; or the

SAFEGUARD BLUE

Built-in Fluid Trap may not be attached to the

SAFEGUARD BLUE

Built-in Fluid Trap connector.
