User Dialysis Meter - Canada

My name is Gil Grenier and I am the Technical Manager for the Nephrology Program at The Ottawa Hospital in Ottawa. We look after seven (7) different hospitals in our region plus 30 home patients with a total of 95,000 hemodialysis treatments per year. We have been using the IBP meters for as long as they have been introduced in Canada, i.e. early 2000s if my memory serves me right. All 20 of my Dialysis Technicians uses them on a daily basis and we have had no problem at all with them. In addition the turn around time for calibration from the company is very short.

I would never hesitate recommending this meter to everyone.

User Dialysis Meter - USA

Presently, I have 7 IBP HDM97BN meters. I originally purchased 4 in June of 2008 to replace Mesa pHoenix meters for the floor staff to use during hemodialysis machine pre-treatment checks. The nursing floor and technical staff were very impressed with the ease of use of these meters; so another 3 were purchased in January of 2009 for the portable bedside hemo machines.

I have had only two problems with these meters, which had been rectified by IBP very quickly. Being these meters are used for approximately 20,000 treatments a year, I find it to be more than an acceptable failure rate per/usage. As compared to the Mesa pHoenix historically at about one a month.

Calibration drift and calibration requirements have been minimal, as compared to the Mesa pHoenix meter. I felt as if we were using the dialysis machine to QA the pHoenix meter.
The 97BN has substantially cut down on nursing staff calibration and maintenance requirements, as well as documentation compliance.

As far as the company being in Germany, it hasn't posed any difficulty. Turn around time has has been within two weeks.

Though the 90DX has been my “gold standard” and reliable for me over the past 15 years, I am replacing my 90DX's with HDM99XP's, instead of the 90XL.

I recommend IBP to anyone.

I have serviced dialysis equipment for at least 16 years. I find that the HDM99 meter is the single most useful tool I have ever used in trouble shooting, repairing and calibrating dialysis equipment. I especially appreciate the fact that features offered on the HDM99 provide such precise output that I rely on my meter as an absolute "final word" in resolving calibration discrepancies. The HDM99 has proven to be an invaluable tool in verification of systems and algorithms used in the diafiltration machine we have developed. The PC interface makes data acquisition and charting easy.

I do have one minor complaint in the form of a question: why didn't you provide such a great tool ten years ago?

Please accept our thanks for allowing Renal Care Group, Inc. to evaluate the IBP HDM97 Dialysis Meter. RCG has long been in search of a dialysate meter that combines the capabilities of accurately measuring conductivity, temperature, pressure, and pH with reliability and durability.
In addition, to the aforementioned criteria, we have been searching for a dialysate meter that is functionally easy for out Biomedical Technicians to calibrate and maintain.
We believe the IBP HDM97 meets or exceeds all these criteria. In my 22 years of experience, HDM97's accuracy is unprecedented particularly in regard to pH measurements. The conductivity cell's accuracy and durability are unparalleled as well.
The HDM97 has forced us to redefine our thinking in regard to what is “State of the Art.” Clearly, the HDM97 Meter sets the “Gold” standard for the dialysis industry. We look forward to using these meters throughout our system.
Finally, RCG looks forward to evaluating the HDM99-dialysate meter. We believe the added capabilities of the HDM99 will find significant use in our research departments thus facilitate RCG's plans to deliver the best and most optimal plan of care to our thousands of patients.

Re: Conductivity meters

We use the IBP and they are fantastic. They have a flow meter a flow through condo temp probe that can be transformed into a dip probe. It has a built in volt meter and oscilloscope. They are by far the best meter I have ever used.

Re: Conductivity meters

Hi Rene, I don't know what kind of machines you have, but when I was working with Fresenius we found that the Neo 2 meters consistantly read high, just like the Neo 1's would if you forgot to ground them (the Neo 1's worked fine if they were grounded).

I used a IBP 99 and I have to agree, it is the best meter that I have ever used by far. It was stable and accurate and easy to use.

Re: Conductivity meters

Hi Rene, that got me thinking. I know the condo probes on the Fresenius machines use changes in frequency, but I never stopped to think what method was used in meters.

I don't think that you can ground an IBP meter. There is no provision on them to do that. They are certainly accurate enough with no grounding. Unfortunately, even if I wanted to I couldn't try it now. Since I left Fresenius and came to Humber I have had to make due with a Mesa.

Another thing to consider with the Neo 1's. If they get to cold they have to be recalibrated. If anyone forgot one in their cars and it was anywhere near 0 Celsius, it would have to be recalibrated. I accidentally forgot my IBP in my trunk last winter when it was about minus 20 (probe was empty and fairly dry). I let it warm up for a couple of hours when I got to the office then checked it. It was bang on and didn't seem to have suffered ill effects.

Good luck in your search.

First rate engineering has developed a pair of reference meters with class-leading specifications, unrivalled versatility and 100% reliability over the last two years. With few exceptions, customer evaluation of the HDM meter has resulted in immediate purchase. The ability to measure the conductivity of either RO water or dialysate; use of the flow meter to set RO output flow; and pressure readings displayed in various units are major attractions of the meters.

The calibration service is both quick and efficient, minimising down-time for our customers.

Probably the most valuable piece of equipment in the dialysis technicians armoury of tools is the conductivity / temperature monitor. Technicians are expected to calibrate dialysis machines accurately and quickly, possibly at some distance from base. Laboratory results are not always reliable so reliance falls heavily on the conductivity / temperature monitor.

I have been asked to convey to you my experience with the HDM99 Dialysis measuring system. At the Lister we have been using one instrument for 18 months and now have a second.

The system consists of a Display unit, conductivity/temperature/pressure probe, pH probe, flow sensor, voltmeter, leads and power supply. Software is supplied which enables PC/notebook display and data logging via the monitors RS232 port. The whole system is housed in an aluminium carrying case with enough space for the tube, 'Y' pieces, connectors, adapters and syringes that become part of a kit.

The LCD display is easily readable and well organised with a digital, bargraph and graphical representation for each individual parameter. Up to 4 parameters can be displayed together in digital and bargraph format. The graphical display is a rough guide on the monitor but very good on a notebook. The parameters included are Conductivity, temperature, pressure, pH, flow, voltage - plot and oscilloscope, frequency
Conductivity ranges between 0 µS/cm to 20 mS/cm enabling use on RO water to dialyser fluid. The probe can be used in line or dip. Temperature ranges cover dialyse and hot rinse with no correction factor required for high temperatures. Parameter ranges and graph time bases can be individually set.

The system has vast capability and it takes some time to become conversant with all the facilities, however one facility that has enhanced routine maintenance is the recording of conductivity and temperature. During maintenance bicarbonate and acid concentrate mixing levels are checked and set. The HDM99 is set up to display on a laptop, the graphical display enabling rapid and accurate determination of correct settings. The session is recorded, displaying original levels, adjustments, and final levels. The complete recording is then saved to a file in the machine records along with the electrical safety test.

There is facility to interface with a dialysis machine directly via RS232 ports using a driver available from IBP. I have not had the time to investigate this facility yet.

Annual calibration involves returning the instrument to IBP, the turn round being within 2 weeks. A full comprehensive calibration certificate is issued guaranteeing temperature, pressure and voltage for one year and for conductivity and pH with monthly verification against standards.
The monthly verification with the standards is quick and easy.

The graphical display and logging facility is particularly useful. Accuracy, confirmed by the monthly checks, appears to be good. The wealth of measuring parameters takes some time to become fully conversant with. The voltage plot, counter and oscilloscope, although useful for some measurements do not replace standalone instruments. A clamp to secure the monitor to the dialysis machine would be an improvement.
Overall I am very pleased with the monitor.
