3/Description and Specications
3.1 Description
The PTS-CVR is a lightweight, compact unit used throughout the hospital primarily for pharyngeal/tracheal suctioning
(airway management). Various models provide regulated or full-line vacuum for hospital suction procedures.
There are several models of the PTS-CVR. All models contain a vacuum gauge which indicates suction supplied by
the regulator. Each has a positive pressure safety relief valve to prevent pressurization by either failed injector vacuum
(Venturi®) units or inadvertent cross connection to pressurized gasses. In addition, the Low PTS-CVR models include a
vacuum relief valve to limit maximum suction.
Some models operate in a regulated or non-regulated MAX mode. Others operate only in the regulated mode.
In the non-regulated MAX mode, the vacuum source is connected directly to the tting/patient port. The regulator module
is bypassed and full-line vacuum is provided.
In the regulated mode, the vacuum source is connected through the regulator module which functions as an automatic
valve. Turning the suction control knob adjusts the position of the regulator module and allows selection of a
predetermined level of suction when set according to instructions.
During use, as the ow requirement increases, the valve automatically opens to maintain suction at the preset level.
When the ow requirement decreases, the valve automatically closes to maintain suction at the preset level. The same
mechanism compensates for changes in supply vacuum and automatically maintains the pre-set suction level when set
according to instructions.
1. Suction Control Knob - Allows easy adjustment of suction to the patient.
2. Mode Selector Switch - Allows quick and easy mode changes.
a. | (ON) - Suction can be adjusted with the suction control knob.
b. O (OFF) - No suction is supplied to the patient.
c. MAX - Maximum full-line vacuum is supplied to the patient.
3. Vacuum Gauge - The suction level to the patient is displayed during use.

6.3 Suction Level Limit Setting
(PED/NEO/C.A.S.S. Models ONLY)
WARNING: This Low Vacuum Limit Setting Procedure
must be followed when repairing Low Vacuum
Regulators. Failure to do this may result in
suction exceeding the prescribed level.
6.3.1 Vacuum Relief Valve Adjustment
1. Remove the cover (see Section 6.2.1 Disassembly).
2. Connect the supply vacuum to the adapter/probe
port.
3. Connect an external vacuum test gauge to the patient
port.
4. Move the mode selector switch to | (ON).
5. Slowly rotate the regulator module to increase the
vacuum level. Note the suction level at which the
relief valve opens. The relief valve should open at
140 mmHg ± 5 mmHg (18.7 kPa ± 0.7 kPa) on the
external test gauge.
6. If adjustment is required, grip the vacuum relief valve
rmly with pliers and rotate the screw about 1/8 turn
with a screwdriver. Repeat the previous step and
check the suction level at which the valve opens.
Note: Clockwise rotation will increase the suction
level at which the relief valve opens. Counter-
clockwise rotation will decrease it.
7. Lock the adjusting screw with a drop of removable
thread locker such as Loctite 242. Repeat step 5 to
verify the vacuum relief valve setting.
8. Re-attach the cover (see Section 6.2.2 Assembly).
WARNING: Excess Loctite®may seal the steel ball to
the seat. This will disable the vacuum relief
valve and may allow suction to exceed the
preset limit.
CAUTION: When Loctite is used on the vacuum relief
safety valve, ensure that it only contacts the
metal parts. Loctite causes many plastic parts to
deteriorate.
6.3.2 Vacuum Limiting Set Screw
