97th day of attachment

My colleague and I sent back a quite a few transport physiologic monitors to the emergency and ward 12 and 13 as quite a lot of devices are placed on the self for returning the devices. I went out with my colleague to do preventive maintenance for the remaining few of devices.

After charging a brand new battery overnight, the pump still unable to run on batteries. I believe that there may be a battery circuit must have been open circuit. Therefore, I used wires to reconnect the circuit and using a DMM to test the continuity of the circuit. However, I feared that might I do not have to ability to accomplish the repair before I left as I have been dealing with it for a month and so. After reconnecting the circuit with insulated wires, the circuit is able to run on batteries. However, Air-in-line indicator keeps lights up even when the water tubing in inserted to the pump. It may be the air-in-line detector is stained by the solution. I wiped with the alcohol pad and the air-in-line detector goes off once I inserted the tubing.

Initially, I thought I have finished one pump. Sadly, Error 2 appeared again. It seems like I am back to square one again. May be the microcomputer that was used for the rotation is faulty. There are so many possibilities that lead to the error 2. Therefore, I start checking the continuity of the circuit that controls the motor rotation.

I replaced with another display circuit board and found out that the IC4 is not the problem that caused it. Therefore, I have to find other resort to this problem instead of just changing the whole HIC board without knowing which part truly affects the HIC board that gave this problem.

Disconnecting the battery circuit to find out which component is affecting the error 2 as before reconnecting the battery circuit, the LED display did not indicate error 2.

In the late afternoon, I analyzed two devices, otoscope and pump control from alternating mattress pressure system, and they are functioning properly.

I went to ward 12,13 and day surgery for asking Nursing officer to sign for condemnation certificate for a mattress pump, giving staff nurse a BP cuff and replacing the adapter and BP cuff respectively.

There was a visual alignment that is a 2-hours talk about innovations on how to provide a better healthcare with a lower health cost. There are a few head of departments making inspirational speech about their innovative ideas and passion for what they are doing. The speech that I found most inspirational is Mrs Denise Kwan’s as she talked about how she gave up her profession and give her 100% attention and care to children with special needs by setting up a school, pathlight school. All of her funding came from the charity and almost sell her house in order to pay for the expenditure that she used for the school.

After the visual alignment, I went to ward 4 to analyze the fault of a personal protection respirator that is also known as the Jupiter mask. The fault is the black ball could not reached to the making on the cylinder during calibration. I have to give a full calibration in order to detect the fault lies with the device or the filter. While I doing the calibration, the ball seems to rise much slower than the other masks. When the calibration is done, the mask is functioning properly.

There is a transport flowmeter, from Drager, the rubber seal missing. Without the bodok seal, oxygen will be leaking at the outlet. Therefore, I replaced the bodok seal and the flowmeter functioning properly.

I used a fuse component from a spoilt HIC board to another HIC board that I used for the infusion pump. I am going to test the battery life for it after charging it overnight. I hope that I am able to accomplish one infusion pump before I leave in 2 weeks’ time.

Transferring a total of 100 signatures in the local driver to update our system of who we hand the equipments to.

We returned some devices back to the various wards since we had to replace a SpO2 sensor for a propaq at ward 4. However, while we replaced with the new one, we found out the new sensor is not working too. The sensor is under 3 months’ warranty so there is one to one exchange for it.

Most of the thermometers that we used for the sparrowhawk exercise are returned. Before storing them back to the Emergency Store Room, we have to perform a check to all the thermometers to make sure they are still at their working state. It would take about half an hour for the Terumo Calibrator to have a temperature of 40oC.

The PCA pump that was sent to BME since last week indicating that the handle is cracked. After giving a physical inspection, there is a small crack and I amended the crack by gluing back. While I was adjusting the volume for bolus and loading dose, the buttons are not working. Therefore, the buttons are faulty. I disassembled the pump and found out the connector that connects the button assembly with the main board came out. Reconnecting the buttons assembly to the main board allows the user to press for desirable values and turning on the device. Necessary tests are to be proceeded in order to finish the job for the PCA pump.

Battery test is done for the STC-508 to complete the preventive maintenance that was due last May.

Portable Slit Lamp, SL-15 from kowa, was sent for repair due to the user dropped it on the floor yesterday. Once the handle crack or broke, the slit lamp required servicing and calibration, as the measurement will no longer be accurate.

An opthalmoscope sent for repair, as there is no light regardless of battery being fully charged. The lamp bulb most probably blown as it works after replacing with the head. Therefore, I replaced the bulb and the opthalmoscope works fine.

An oxylog ventilator having too high minute volume when the user doing the flow test. This problem seems quite frequent. However, this time is different from the others from MICU. This time the minute volume was 7.4. It may cause by either the tubing or the patient valve. For this case, it was the tubing that caused this problem. We replaced the tubing for them.
