EBME Forums Forums Maintenance Test Equipment 500ml Rigid Container - NIBP Testing

Good morning

Could someone point me into the correct direction to purchase a suitable 500ml Rigid container for NIBP testing?

Thanks

Fluke Biomedical has the chamber listed as an accessory but costs nearly $500 !!

I have the original Siemens Draeger 500 ml NIBP conditioning chamber and a set of three from Nihon Kohden 700, 500 & 250,but these were purchased almost 40 years ago and all the reference numbers have long since peeled off.

Maybe someone could 3D print one??

Fluke Biomedical's products are not the best.

They are usually very expensive, and there are no updates in the core technology; in my opinion, the upgrades are only in the appearance, screen, and other aspects.

Absolutely no value for money, and they don't even provide a service manual with schematics. Terrible manufacturer, bad review.

Furthermore, they like to acquire excellent companies, which only worsens the industry and creates a monopoly.

Hi Neo,
i seem to recall someone making this kinda thing in house some years ago out of some pipe and end stops .

Are you guys discussing this?

No buddy, thats a mandrel. i THINK they are referring to a reservoir for bp testing...ie...a hollow container of known volume

Yes - and as you mentioned above - should not be beyond the capabilities of "local manufacture".

A length of polythene pipe could be a good starting point.

What level of accuracy is being aimed for (+/- 5%, I should imagine)? How to measure the volume? - with a calibrated water column, perhaps.

A nice project for an apprentice.
