The application provides a mechanical heart valve function detection device 10, which is used for carrying out function detection on a heart valve of a patient implanted with the mechanical heart valve. When a user holds the mechanical heart valve function detection device 10 for detection, on one hand, the mechanical heart valve function detection device can be well attached to a human body, so that a good detection effect is obtained. On the other hand, the detection data can be viewed in real time in the detection process.

Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of a mechanical heart valve function detecting device 10 according to the present application, and fig. 2 is a sectional view of the mechanical heart valve function detecting device 10 of fig. 1.

As shown, the mechanical heart valve function detecting device 10 includes a housing 11, a heart sound detecting assembly 12, and a display 13.
