Amvex Vacuum Regulator
OHIO MEDICAL, LLC · Model LPA
VR-LP series, VacReg, Ped Int 3Mode 200mmHg, Analog.
Intended use: A noninvasive device/collection of noninvasive devices designed to connect to the terminal unit (wall outlet) of a vacuum pipeline system to control the degree of negative pressure during the evacuation of fluids, mucus, or solids during a range of clinical applications (e.g., not dedicated to thoracic suction). It allows continuous and/or intermittent suction at variable levels, incorporates a manometer and controls for monitoring/adjusting the level of suction, and may include collection containers, tubing or a stand/mount; it does not include patient contact devices (e.g., handpiece/tip, catheter).
Key tips
- ·Always leak-test under load - a regulator that reads correctly at rest can still leak and fail in real use.
- ·Canister and tubing changes are an infection-control issue as much as a mechanical one.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Will not reach or hold set vacuum
HighSymptoms: Regulator will not pull the set vacuum, gauge drifts, or vacuum bleeds off.
Root cause: Worn regulator diaphragm / valve seat, a cracked gauge, or a wall-supply / connector leak.
Gauge inaccurate
MediumSymptoms: Displayed vacuum does not match a reference gauge.
Root cause: Gauge mechanism drift or damage.
Leak at the DISS / wall connector
MediumSymptoms: Hiss, poor vacuum at the patient, will not seal to the wall outlet.
Root cause: Worn DISS nut / nipple seal or a damaged wall adapter.
Mode / knob mechanism fault
LowSymptoms: Regulation vs full-vacuum mode selector loose or ineffective, knob stripped.
Root cause: Worn selector / control knob.

- ·Canister / tubing replacement
- ·Annual full PM
Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Will not hold set vacuum
- Connect a known-good reference gauge and compare readings.
- Cap the patient port and check the vacuum holds.
- Inspect the DISS connector and wall outlet for leaks.
- Rebuild the regulator with the diaphragm / valve kit.
- Re-verify against the reference gauge across the range.
Symptom: Gauge reads wrong
- Compare to a calibrated reference at several set points.
- Tap the gauge to rule out a stuck needle.
- Replace the gauge.
- Re-verify.
- Label with the calibration date.
