Functions and Specifications

Blood pressure measurement

☐ There are two ways of utilizing this device to record blood pressure measurements.
Automatic measurement - This automatic measurement works in accordance with internal clock, preset time intervals and preset mode. The measurement data is saved in memory.
Manual measurement ---- Any time you press the START STOP key, a blood pressure measurement is performed immediately. The measurement data is saved in the memory.

Automatic measurement

☐ This measurement starts or stops using the AUTO ON/OFF key. When this measurement is started, the recorder begins to work in accordance with preset time intervals from the preset time of the internal clock. Refer to "Selection for the automatic measurement".
☐ In the automatic measurement, an "A" appears in the upper left of the display.
☐ The recorder automatically measures the patient's blood pressure at the time that is pointed out by "the frequency" and "the start time" (by the programmed time intervals).
☐ When a measurement error occurs and there is 10 minutes until the next measurement, the measurement is retried after approx. 30 seconds.
☐ If a measurement is retried, only the data from the retry is saved.
☐ The recorder automatically adjusts the proper pressure, exhaust velocity and end of measurement.
☐ Refer to "Selection for the automatic measurement" and "Automatic measurement by programmed time intervals" about operation and entering parameters.

Stopping a measurement

☐ If you press the START STOP key during a measurement, the recorder exhausts the air and stops the measurement.

Concealing the measurement value

☐ This function works only while using automatic measurement.
☐ This function does not display the SYS, DIA or pulse rate for the automatic measurement, but the data is saved in memory.
☐ This function can select "reveal" or "conceal" at "Parameters for the display and clock". Refer to this section.
☐ If you select "conceal", the recorder displays the clock during a measurement.
☐ If you reset the recorder, this parameter is set to "reveal".

Pressurization

☐ The pressure is automatically selected by the recorder while in the automatic measurement mode.
☐ The first pressure is set to approx. 185 mmHg. This value automatically adjusts to the proper value after the first measurement. If the first inflation is not successful, the recorder retries twice.
☐ If you reset the recorder, the first inflation value is reset to 185 mmHg.

Memory

☐ The TM-2430 recorder can store 300 sets of data.
A data set consists of a SYS, a DIA and a pulse rate.
☐ When memory becomes full, the recorder displays an "M". Until you clear the data, you can not measure blood pressure.

When the recorder saves data for more than one patient, data management becomes complication. We recommend that patient data is transferred and cleared from memory.

When a "B" is displayed, the backup batteries that is preserving a patient's data are weak. Please replace batteries as soon as possible.

ID number

☐ If you reset the recorder, the ID number is set to "1".
☐ The ID number can be set using the optional software.

Patient instructions

Advise the patient on how to cope with mis-operation and contingencies.

Cautions during automatic measurement

☐ Patient should relax and be quiet, when the recorder starts inflating the cuff.
☐ Minimize noise and movement during the measurements.
☐ The recorder displays the patient's blood pressure within one minute after the measurement.
☐ There is the possibility of re-measuring the blood pressure after the last measurement. This occurs when the recorder did not acquire usable data and the frequency of the interval is above 10 minutes. The patient should relax and not move during the measurement.
□ Discontinue use of recorder if the patient feels pain in his arm.

Stopping or canceling an automatic measurement

☐ When the patient needs to stop a measurement, press the START STOP key. The recorder beeps, releases the air in the cuff and an error is displayed. The recorder will inflate the cuff for the next time period automatically.

☐ When the AUTO ON/OFF key is pressed and held for approx. 3 seconds, the recorder exits the automatic measurement mode and the "A" disappears. Conversely, by pressing the AUTO ON/OFF key again, the "A" will reappear.

Manual measurement

☐ For the patient to start a measurement at once, press the START STOP key.
☐ For the patient to stop this measurement, press the START STOP key.

Attention while attaching the cuff and recorder

☐ Do not drop or shake the recorder.
☐ The recorder and cuff are not water resistant. Prevent excessive moisture wetting the recorder and cuff.
☐ Do not place anything on the recorder.
☐ Prevent the air hose from disconnecting during sleep. Affix the air hose to the patient's body only as shown on page 24.

Replacing the batteries

☐ Replace with new batteries quickly, when "B" is displayed.

Use of the cuff cover

Step 1

Attaching the cuff and recorder

Caution

☐ The standard cuff that is included with the TM-2430 is a left arm cuff.
☐ If the cuff is not attached at the correct position, the recorder may not measure the blood pressure correctly and an error may occur.
☐ The left cuff is for use on the left arm of about 20cm \~ 31cm. If you need a different cuff, purchase a cuff of the proper size and arm position. Refer to "Option and Accessories".
☐ Do not use, if the patient has dermatitis, etc.

Keep the cuff clean. Exchange the cuff cover for each patient. The cuff cover may be used for both right or left.

Steps for attaching the cuff and recorder

Step 1

Make a circle where the end of the cuff is passed through the ring.

Step 2

Search for the brachialis artery using palpation.

Step 3

Attach the cuff directly against the skin so that the yellow mark is directly over the brachialis artery and space it one inch above the inside of the elbow and the lower edge of the cuff.

Step 4

Wrap the cuff so that the ring is within the slide range, it is flat and does not slip down, but has room to insert two fingers. (If the ring is not within the slide range, you need a proper cuff.)

Step 5

Position the air hose over the shoulder and affix it on the patient using adhesive tape.

Step 6

Assemble the belt and carrying case.

Step 7

Position the belt so that the carrying case is on the right (left) side of the patient, when a patient attaches left (right) arm cuff.

Step 8

Connect the air hose plug to the air socket.

Step 9

Place the recorder into the carrying case.

Caution

☐ Do not disturb the cuff or air hose during the measurement because the recorder measures small pressure variations.
