Avoid accidental damage
by sharp objects
Your assembly is a durable device when handled appropriately,
but cannot withstand abnormal forces.
Don't allow contact of any part of the assembly with sharp objects.
The sleeve membrane is especially easily punctured by sharp
objects as it is very thin.
Take care
with flushing
the assembly
Vigorous flushing, especially with small volume syringes, can
produce very large pressures within manometric channels which
can rupture them. Assemblies with closely packed channels are
the least resistant to this abuse.
The sleeve should be flushed with special care. Heavy flushing
can rupture the sleeve membrane at the point of entry of the
perfusate into the sleeve channel.
Don't try to flush a balloon channel if your assembly has one!
These are fitted with a male nylon connector and a red luer
locking ring, so they are easily distinguished from manometric
channels. |
 |
Prevent soilage
and blocking of channels
Don't allow non-perfused channels to fill retrogradely with
body fluids. Before intubation, water-fill the channels that
will not be perfused, and seal the luer connectors with the
white nylon plugs supplied.
Gently flush all channels as soon as possible after use with
a mild detergent solution and then water.
If you cannot flush an assembly immediately, it must be placed
in water to prevent drying of secretions.
Be careful if a channel is blocked
| |
Don't flush blocked channels
as hard as you can. You may damage your assembly irreversibly.
|

Follow the procedures
described in our Technical Note 4, Version 2, Procedure
for unblocking channels. |
Treat the luer connectors kindly
Twist these connectors as you remove them from transducer
luers by rotating the wings of the connector between the finger
and thumb as they grip tightly. Because of the grip of the
connectors on the luers, they can be torn if they are pulled
upwards without rotation. These connectors are designed specifically
for manometric assemblies. They stretch over the transducer
male luers and so provide a tight zero deadspace connection
that gives excellent pressure rise rates. |
|
Clean and disinfect your
assembly with care
Disinfection is no substitute for adequate initial cleansing
of your assembly. The assembly should be flushed internally
and wiped externally in a warm detergent solution.
Autoclave your assembly between each use.
Please refer to Dentsleeve Technical
Note 3, Version 2, Cleaning and sterilisation of Dentsleeve
assemblies (page 68).
Visually inspect your assembly before each use to
| |
Ensure that it has not
been damaged by excessive force applied during prior use
and cleaning.
|
| |
Check that any metal stiffeners
remain safely encased. |
We recommend that you also check the integrity of the sleeve
sensor. When the assembly is connected to the perfusion pump,
and the perfusion running. Occlude the distal margin with a
finger.
The recorded pressure should be allowed to ramp up to 100mmHg.
If this does not occur, the sleeve membrane must be leaking
and will not give reliable recordings. For further information,
see Dentsleeve Technical Note
2, Version 2. |
