ERKA Switch 2.0 Simplex Sphygmomanometer

No, it is a mercury-free mechanical aneroid sphygmomanometer. A clinician inflates the cuff manually and reads pressure from the dial while listening with a stethoscope.

Simplex identifies the single-tube configuration within ERKA's Switch 2.0 family. The tube connects the cuff and inflation system to the handheld gauge assembly.

No, pressure is created with a hand bulb and released through a manually controlled valve. It therefore has no motor, batteries, automatic averaging, or stored readings.

Manual auscultation lets a trained professional hear Korotkoff sounds directly and control the cuff's deflation rate. It can also be useful when an irregular pulse or patient movement makes an oscillometric electronic reading questionable.
