Started at the end of positive pressure equipment, went through central delivery systems (MAKS, DW 4009) with negative pressure. Staff all had calculators in their pockets and emesis basins were always handy. Technology has come a long way but still has a ways to go

We used trash cans to catch it from 5 ft away. Acetate was nasty! My first machine was the DW 4019 I believe the number was. |

Started in a hospital with the Travenol 100 liter batch tanks. Soon after moved into a new facility with the DW 4009 central and still using coils for a couple more years. There was a lot of technology improvements in the hemo machine in the late eighties thru the nineties. After that attention was on the water treatment area.

I started with the original Cobe Centry machines and the Drake Willock 4002s. Most of the advances I saw in my early years improved patient safety. The Centry machine drew up concentrate by means of a rotor turning on a piece of silastic tubing. The problem was that the length of the tubing was completely adjustable. That tubing was always going out of adjustment. Cobe later came out with fixed length tubing. As best as I can remember the machine had a standby mode and an operate mode. It was possible for the switch to fail in such a way that it sent 120 volts of AC into the DC circuitry and wiped out every circuit board in the machine.
The 4002 had controls in a Samsonite case. There was an adjustment with a large knob for the blood leak detector sensitivity. It was possible for someone to accidentally turn down the sensitivity so much that the blood leak detector wouldn't detect any leak.
Drake made improvements with the 4015, but they failed to improve the conductivity monitor. The lower conductivity alarm limit had to be turned all the way down when the machine was in rinse. It was possible for a patient to dialyze with the lower limit turned all the way down. The 4215 took care of the conductivity alarm limit issue, and Drake later added a redundant alarm.
I heard that some group wanted to honor the legends of dialysis, both living and deceased. I am not sure what happened with that project, but someone wanted to change the name of the project to dinosaurs of dialysis.

went through central delivery systems (MAKS, DW 4009) I hated the MAKS. Our nurses/techs would let the pump run dry and destroy the impeller. At that time the only place I could get them was a pump supplier about 40 miles away. The third time it happened I bought three or four just to have extras on hand. I ended up getting in trouble for buying more than I needed, plus they didn't like the mileage I wracked up going to get them. Did they tell the nurses/techs not to run the pump dry? Of course not. I ended up leaving that clinic not long after that. About five or six years later I was talking with another biomed and after comparing notes, it turned out he was the biomed at that clinic after I left. He said they still had the same issues that caused me to leave and he stayed there less than a year because he feared being fired as a scapegoat for things the nurses and techs were getting away with. |
