The invention provides a multi-parameter vital sign detector, and belongs to the technical field of medical instruments. The multi-parameter vital sign detector comprises a measuring subsystem, a processor and a clamping connection seat; the measuring subsystem is used for measuring parameters of various vital signs of a measured object and transmitting the parameters of the various vital signs to work stations through the clamping connection seat, and the clamping connection seat is in electromechanical connection with clamping connectors of the work stations under the action of buckle structures. The multi-parameter vital sign detector can be electrically connected to the work stations conveniently, so that observation and comparison can be conveniently performed.
