Merit Medical Meritrans Disposable Pressure Transducer - Manual

DISPOSABLE PRESSURE TRANSDUCER - INSTRUCTIONS FOR USE
DESCRIPTION
The Meritrans is a pre-calibrated, single use device for physiological pressure measurement. A
separate reusable interface cable is used with this system to connect the transducer to a pressure monitor.
The Meritrans may be used with a manifold, pole mount organizer, or attached directly to the patient via a strap.
SET-UP
CONNECTIONS
1. Using aseptic technique, open the package containing the sterile transducer.
2. Set-up according to hospital protocol for pressure
monitoring procedures. Connect to other
monitoring equipment (e.g. manifolds, stopcocks, flush devices, tubing administration sets, etc.)
CAUTION: Make sure that all connections are tight. To prevent stripping, do not overtighten.
3. Ensure that the connectors are dry.
4. Connect the Meritrans disposable transducer cable to the reusable monitor cable.
5. Extract all air from the flush solution container.
CAUTION: If air is not extracted from the solution container, air may be forced into the system when the fluid is
depleted.
FILL LINES
1. Remove caps (if any) from stopcock on transducer and open the system.
2. Fill all lines with sterile flush solution until free of air bubbles.
NOTE: Merit Medical recommends gravity filling the system rather than pressurizing the flush
solution to avoid generating bubbles in the solution.
CAUTION: Verify that no air is trapped in any components of the fluid pathway. Air bubbles can cause serious
patient harm and will negatively impact pressure wave forms.
3. Turn stopcock off.
4. Using sterile technique, replace vented caps with non-vented caps.
5. Repeat steps 1-4 for any additional stopcocks or ports.
6. Pressurize the I.V. solution source to 300 mmHg.
ZEROING THE SYSTEM
1. Zeroing should be performed after the system has been filled and mounted.
2. Turn the pressure monitoring system “off” to the patient.
3. Verify that the opening of the stopcock to be used for zeroing is positioned at the patient’s
mid-axillary level.
4. Being careful not to contaminate the zeroing port, turn the stopcock handle to open the port
at the mid-axillary level to air.
5. Zero the transducer according to the monitor manufacturer’s instructions.
6. Turn the stopcock handle “off” to the open port.
7. Turn the pressure monitoring system “on” to the patient.
CAUTIONS: Before injecting, turn the manifold handle to the transducer off in order to isolate the transducer from
pressure.
CONNECTING TO THE CATHETER
1. Connect the monitoring kit pressure tubing carefully to the patient’s catheter or sheath so that
no air is introduced into the system.
CAUTIONS:
1. The Meritrans is a single use item. Contents sterile unless package is opened or damaged.
Do not reuse or resterilize.
2. Federal (U.S.A.) Law restricts this device to sale by or on the order of a physician.
3. Do not autoclave the reusable cable.
4. If the transducer is used to measure left arterial pressure, an air eliminator filter must be
installed between the solution source and the transducer.
5. Components of the pressure monitoring system in contact with the fluid path must be kept sterile.

REUSE PRECAUTION STATEMENT
For single patient use only. Do not reuse, reprocess or resterilize. Reuse, reprocessing or resterilization may com-
promise the structural integrity of the device and/or lead to device failure which, in turn, may result in patient
injury, illness or death. Reuse, reprocessing or resterilization may also create a risk of contamination of the device
and/or cause patient infection or cross-infection, including, but not limited to, the transmission of infectious dis-
ease(s) from one patient to another. Contamination of the device may lead to injury, illness or death of the patient.
