40th DaY oF aTtAchMent
After doing the maintenance for pumps for the past few days, I only left pumps from SICU. Unfortunately, I only able to find the graseby 3100 syringe pump as most of the terumo syringe and infusion pumps are used by the patients. When I reached there, I found out there are more patients than usual so I tried not to take the terumo pumps as they may be needed. The ward seems pretty much hectic as each nurse as to take care one or more patients at a time including the nursing officer of the department. It is the first time that I saw hem being so busy.
For today, I did more repair than maintenance since many pumps are unable to be brought down for maintenance. I got to see commission of the single flowmeter from Allied healthcare. There were 30 flowmeters being bought by us so it took gary oon from star medical close to 2 hours to complete the checking of device. They had their own calibration analyzer and a leakage tester which is a bottle. The flowmeter is being calibrated at 50 PSI. They will measure each LPM marking on the flowmeter and the tolerance of it is like +/- 1 of the stated value. For the leakage test, the flowmeter will be connected from the oxygen tank to the tester which is half filled with water. If there is a leakage, bubbling will occur.
Operation theatre at level 3 passed me the PCA pump, Graseby 3300 yesterday due to the start button unable to initiate the infusion. I tried turning it on and it seems alright but after doing a few times, I met the same problem as the end user who is doctor and nurses. Therefore, I asked Mr Toh for guidance and he told me mostly probably it is the user did not know how to use it. Mr Sin then came in and told me that there are two causes that may arise this problem which are the incorrect settings done by the user and the cover did not closed properly. Sometimes, there will be some error message displayed but the user will just ignore it. There are many safety locks for this device due to its function which is injecting morphine to the patient. It is necessary to have locks to prevent over dosage of morphine. If over dosage occurs, the particular nurse to administrate it will have to be reported and unable to continue her/his job as a nurse.
Lastly, a flowmeter sent to BME for repair as the complaint from ward 13 was that the metal ball in the meter unable to drop to zero when the knob is totally closed. Usually, we will change the whole flowmeter with their oxygen gas probe unless it is the internal glass tube is broken.
