Kallmeyer Medizintechnik

ERKA Kallmeyer Medizintechnik is a long-established German medical device manufacturer best known for blood pressure measuring instruments, stethoscopes, cuffs, and related diagnostic accessories sold under the ERKA brand. The company traces its roots to 1889 and positions itself as a pioneer in mechanical blood pressure measurement, with products manufactured in Germany and distributed internationally. Its business is focused on commercial-stage medtech products for physicians and healthcare professionals rather than a therapeutic drug pipeline. As of 2025, the company entered insolvency proceedings in Germany, but reporting indicated that operations were continuing during the process. The company also appears to have ongoing product development and IP activity, including patents related to non-invasive measurement and stethoscope protection.
