Maintenance for Medical devices -

00:00:01 hello and welcome everyone today I would like to talk about maintenance and especially maintenance for medical devices well first of all there's two types of Maintenance there is the CM the corrective maintenance which means the maintenance that happen when the device break down okay and this maintenance Could Happen anytime when the device has a problem second type of maintenance which is PM preventive maintenance means which means a maintenance that I do regularly depends on the protocol and the type of 00:00:39 device and I do this type of Maintenance to prevent the device to break down or to have a problem in the future okay so for example I want to check sensitivity of the valves of the sensors Etc now there is something here if I'm talking about maintenance so there is three important things to clarify about the maintenance questions that I have to ask myself first of all what is the purpose what is the purpose of the device okay in this question I could understand the maintenance of the device in a reverse 00:01:23 way because the device will give you a error message okay and this error message you could use it to to to decide what is the type of problem and what is where is the location of the problem and therefore how I could solve this problem okay and not necessarily that all the problems would be given from the device from the error of the message some errors actually could read the message that the device gave you and you won't understand what the problem that is possible so first of all I I know the 00:02:05 device I understand the principle of the device okay for example I'm just going to give you an example I have a medical device and this device has has a tank for Waste for water for example okay and when this water is filled completely the device would give me an alarm empty the tank okay but sometimes the problem here for example the scenario that that tank is already empty and still the device is giving me an alarm so the first thing I'm going to think about the first thing that I'm going to consider is the 00:02:51 sensor okay maybe there is a problem with the sensor actually could be the problem okay but I have to think about what is the most most common problem that could occur you should also understand that the history of the device matters in dependence because sometimes a specific device would have the same problem over and over and over so there is actually a record for each device the maintenance record tells you type of of Maintenance that that happened to the device data of it and descri description 00:03:28 about it so might the same problem occurred again so you have to deal with each device separately okay so you have to understand fully understand the principle of the device how the device Works how it actually turn on and you have always to use the book that came with the device the catalog it actually could gives you some information as well and U here I think there's something that very important The Logical way of thinking because eventually maintenance is that is based on regulars wellknown 00:04:17 rules to decide the problem then solve it and solving the problem with the most possible minimum cost and time for example sometimes you you know that the the problem is related to them the aboard we have in the device there is a board electrical board is not working so I have two ways either I'm going to replace the whole board and that could cost a lot or I could fix the specific problem in the board sometimes seriously the problem would be uh there's a resistance okay the problem in resistance so instead of replacing the 00:05:00 whole board I could just replace the resistance that could cost a lot less than replacing the whole board so always uh someone who is good at maintenance actually could help the company save money let's take another scenario I have a laser device that when it works for 15 minute the temperature of it would increase okay increase so much and it turns off directly from itself because it reaches very it reached a critical point of temperature so what I think the first thing that I have to think about 00:05:40 the sensor of temperature okay if it's it's okay I'm going to think about the cooling system of the device okay sometimes the problem would be S very simple sometimes the device is too close to the wall against it I have to give it distance okay sometimes the problem could be like that sometimes there a little dust in in this answer so um sometimes the fan is not working the right way there there is for therefore there's not uh the temperature would stay high so and always there is there is a label 00:06:25 should be stuck to the device each time the device go through maintenance it says the name of the technician or engineer that did the maintenance the module of the device the series number of the device the position the place of the device what is the problem how we solve this problem okay and the signature of the of the engineer or technician there is actually a form to regulate the process of Maintenance this form should contain the following information first of all the type of device the company that manufactured the 00:07:04 device the series number of the device in the in the hospital or in the organization the time when the device was installed in the in the company okay or in the hospital also the name of the engineer that did the maintenance what is the what is the problem how he did solve it and the feedback which means the user of the device he's could be a doctor could be a nurse what he thinks how does he notice a positive difference after the maintenance okay so we have a form for mainenance we have form for examine the device okay pretty much 00:07:52 the same information but just uh the difference here just say after I check the device he will write the engineer technician I found the device is working very good I noticed slightly for example problem with the engine I notice there is problem with anything okay so very important to keep a record for each device now i' would like to talk about how I if I have a problem I have a device that is not working this device is not working should I how I start think about they say from the beginning to the end or from the end to the 00:08:30 beginning what what I mean like sometimes the device is not working okay could the problem be with the socket of the electricity could be the problem very very complicated the engine in the device is not working maybe there's something wrong with the boards okay so how where this decide okay depends on what depends on the problem actually there is depends on the situation you could understand like sometimes try with the simplest things first okay it's not working try something more complicated but always 00:09:04 avoid to start with the with you know opening the device and removing part of it and no start with the simplest solution the simplest solution okay it could work actually there is Big possible big possibility is going to work and always always read the message the error message that the device give you that the device gives you okay all right I think that it for today so thank you for listening and goodbye.
