Meaning and Definition
A device, typically a machine, used to filter waste products and excess fluid from the blood when the kidneys are not functioning properly.
Broadly, any device or apparatus that separates substances from a solution via dialysis (selective diffusion through a semipermeable membrane). This includes laboratory-scale dialyzers used in biochemistry and industrial equipment.
Dialectal Variation
British vs American Usage
Differences
Spelling: In UK medical contexts, 'dialyser' (with an 's') is the standard spelling. In the US, 'dialyzer' (with a 'z') is used.
Connotations
Identical. Both refer to the same medical device with no difference in connotation.
Frequency
Slightly more frequent in US medical literature due to spelling standardisation. The term is of equal technical necessity in both varieties.

FAQ
Frequently Asked Questions
Not exactly. The dialysis machine is the whole apparatus that pumps blood and manages fluids. The dialyzer is the specific filter unit within that machine where the actual blood cleansing occurs.
In haemodialysis, no. The dialyzer is the essential component. In peritoneal dialysis, the body's own peritoneal membrane acts as the filter, so an external dialyzer is not used.
In modern practice, disposable dialyzers are used for each session. Historically, some were cleaned and reused for the same patient a limited number of times, but this is now less common.
It is a common and essential term within nephrology, healthcare engineering, and related fields, but it is very uncommon in general everyday vocabulary.
