Latex-Free Veterinary Blood Pressure Cuffs Two different types of veterinary blood pressure cuff connectors are available. The non-locking connector (or intact connector) fits the vast majority of oscillometric blood pressure monitors or Doppler blood pressure monitors. These connectors are compatible with Mindray, Lightning, SunTech, and Doppler devices, among many others. Blood pressure cuffs are available individually or as a set of five. The alternative connector is a bayonet connector, which is sold only individually. This connector fits directly with the collar connection and is compatible with the Edan device, among others.
