Prerequisites
• The vacuum connection tube must comply with the hospital's standards for hygiene.
• The inner diameter of the vacuum connection tube must match the outer diameter of the hy-
drophobic bacterial and viral filter.
• The inner diameter of the vacuum connection tube must match the outer diameter of the tube
connector on the bacterial and viral filter.
The vacuum connection tube will be referred to only as ‘connection tube’ below.
1.5.5.3
Hydrophobic bacterial and viral filter
In its function as overflow protection device, the hydrophobic bacterial and viral filter protects the
product against ingress of particles, fluid and foam. In its function as bacterial and viral filter, it
protects the product from the ingress of bacteria and viruses.
Prerequisites
•
Pore size ≤ 1.0 µ.
• The tube connector must match the tube being used.
• The hydrophobic bacterial and viral filter must close tightly against water passage at an abso-
lute pressure of up to 10 kPa.
• If required, observe the direction of flow (see note on the hydrophobic bacterial and viral filter).
1.5.5.4
Septic fluid jar including septic fluid jar cap
The septic fluid jar and septic fluid jar cap are used to collect the secretions extracted.
Prerequisites
• Low leakage.
• Always fasten the septic fluid jar securely.
• The outer diameter of the tube connector on the patient side should match the inner diameter
of the suction tube.
1.5.5.5
Suction tube
The suction tube is used to connect the tube connector on the septic fluid jar on the patient side
and the fingertip or the utensil.
Technical specifications
• Shore hardness of 60
• Inner diameter of 6 - 8 mm
• Length 1.3 m - 3.0 m
• Vacuum resistant down to -95 kPa (must not collapse)
Prerequisites
• The outer diameter of the tube connector on the patient side of the septic fluid jar cap must
match the inner diameter of the suction tube.
1.5.5.6
Fingertip
The fingertip serves to vent the suction tube in order to be able to quickly interrupt the aspiration
process.
Prerequisites
• It must be possible to sterilise the fingertip or it must be a sterilised disposable item.
• The outer diameter of the tube connector on the patient side should match the inner diameter
of the suction tube.
