Precautions for the use of monitor battery

• 1.In order to prevent the monitor battery from being injured or catching fire, do not let the metal sheet touch the battery electrode;
• 2. In order to use the battery of the mobile ECG monitor for a longer period of time, it is best to use the matching charger instead of the inferior charger’;’
• 3. Don't always be in a high temperature or low temperature environment, long time in an environment with too high or too low temperature, it will have a bad influence on the battery life and life of the ECG monitor.
• 4.ECG monitor battery: storage temperature: less than one month: -20~60℃ less than 6 months: -20~30℃
• 5.Avoid frequently charging and discharging the monitor battery, charging or using an external power supply when it is not exhausted, using it while charging, or continuing to use an external connection after charging, which will cause additional loss to the battery.

Portable ECG monitors are generally AC and DC dual-purpose, with built-in batteries, but the charging circuit of such machines is not very complete, generally there is no battery temperature detection and battery discharge circuit, and the batteries are mostly Ni-Cd and lead storage batteries, which are prone to aging And overcharging, the machine is prone to malfunction after several years of use. Two cases of battery malfunction are now introduced as follows:

Monitor malfunction Philipilipenomenon 1: Ohmeda 3700e monitor cannot be turned on.

Troubleshooting: Check the power circuit of the machine and find that the rectifier bridge stack is broken down. After replacing the new bridge stack, it can be turned on, but the mains is still not working. The battery is considered to be insufficiently charged. After a few hours of charging, the monitor cannot start again. After inspection, the bridge stack is damaged, and it can be started after replacement. It is suspected that there is a short circuit in the machine. First, check the components of the power circuit and find that the temperature of LM317 is very high. Looking at its load from the circuit diagram, the machine is the whole machine and the charging circuit when it is working. There is only the charging circuit when shutting down and charging. Because the bridge is broken down in the shut down charging state, there may be a short circuit in the charging part. First unplug the battery. After a few minutes, the temperature of LM317 returns to normal and the machine can continue to work for a long time. Therefore, it is judged that the battery is damaged, causing the charging current to be too large, and the bridge stack is burned. After the battery is replaced, the monitor failure is eliminated.

Monitor malfunction Philipilipenomenon 2: PROTOCOL PROPAQl02 portable monitor can be used normally for ECG, body temperature and monitoring, but cannot measure non-invasive blood pressure. When the air pump is inflated, the machine will black out and the monitor will automatically shut down.

Troubleshooting: Refer to the drawing, the external power supply is only for charging. The main power supply of the machine is the internal battery. Charge for 8 hours before checking to prevent insufficient charging to affect the work. At this time, measure the battery voltage to 8V, enter the non-invasive blood pressure menu, press Press the START button, the air pump works, and the battery voltage drops to about 6.5V immediately, and the machine shuts down immediately. Use a regulated DC power supply to adjust to 8V instead of the battery and insert it into the machine. The blood pressure can be measured normally, and the machine will not shut down. After the battery is replaced, the monitor troubleshoots.

Summary: For many medical instruments, the built-in battery is indispensable in use and should be checked regularly. It is best to purchase a battery analysis and repair instrument, which can be found and solved in time to save the cost of replacing the battery and reduce the clinical waiting time. Limit the protection of medical safety.
