Routine maintenance and repair of defibrillator

Defibrillator is different from auxiliary diagnostic equipment and general therapeutic equipment, once the rescue of the patient can not function properly, it is likely to miss the opportunity to produce adverse consequences, and even cause medical disputes. Below, HP CodeMaster M1723B (M1723B for short) and Philips Heartstart XL M4735A (M4735A for short) as an example, briefly talk about the maintenance and use of defibrillation monitors.

I, pay attention to check the function of the instrument

In the need to quickly determine whether the main function of the instrument is normal or not, you can use the following methods:

1, check the monitoring function

Can be selected in the lead in the Paddles (paddle electrodes), with both hands, respectively, to contact with the sternal electrode plate and apical electrode plate, such as the screen displays an electrocardiogram, indicating that the monitoring function is basically normal. The monitoring function is basically normal.

2, check the defibrillation function

Generally available soap as a medium to observe the discharge sparks. Specific operation: remove the handle from the machine, with a piece of soap clamped in the middle of the two electrode plates, and then "defibrillation charging", charging is completed, while pressing the discharge button. At this time, the electrode plate in the clamping soap, you can see the discharge sparks. The size of the spark is related to the size of the selected energy. When discharging, pay attention to the human body should not touch the electrode plate, and can not be two electrode plate direct short circuit.

Experts remind that the above methods can not replace strict testing. But if even the above checks fail, the instrument must be repaired.

Second, pay attention to the use of the instrument

1, defibrillation operation should be carried out according to the patient's indications, the choice of synchronous defibrillation or non-synchronous defibrillation, and according to the different models, according to the tips of the instrument's operating manual to select the energy.

2. During defibrillation, the electrode plates should be in full contact with the skin and a certain pressure should be applied to ensure good contact.

3. It is best to use conductive paste for external defibrillation to make good contact between the electrode plates and the patient's skin. If saline is used, gauze should be wrapped around the electrode plates, and care should be taken to prevent too much saline from short-circuiting on the body surface.

4, ultrasound coupling agent and conductive paste are similar in nature, but different in nature, so ultrasound coupling agent can not be used instead of conductive paste, so as not to cause poor contact.

5, defibrillation operation is strictly prohibited the use of alcohol, so as not to cause the patient burns.

6, thoroughly remove the conductive paste on the electrode plate after each use and keep the electrode plate clean.

7, each time after the use of the machine battery should be charged in a timely manner.

Three, pay attention to the routine maintenance of the instrument

Preventive maintenance is to ensure that the instrument is always in good operating condition of the key, this work is usually done by the equipment users. General hospitals need to pay attention to the following points:

1, the careful implementation of the instrument turnover system

Each shift should be the following checks: whether the power cord is broken; lead wire, electrode clips (buttons) is intact; a variety of accessories are complete; whether the record paper is exhausted, such as the imminent exhaustion of the replacement in a timely manner and to confirm that the installation of the correct.

2, every shift to run a self-test program

Take M4735A as an example, after the instrument passes the self-test, a report will be printed; if there is a prompt "Serves Unit", it means that the instrument fails to pass the self-test, and the engineers and technicians should be notified to deal with it in time.

3. Clean the exterior of the instrument once a shift

Pay attention to cleaning the display with a soft cloth; use 90% alcohol or neutral soapy water to clean the exterior, but should prevent the liquid from flowing into the machine.
