Referring to fig. 1 to 4, according to an embodiment of the present utility model, a push-type ultrasonic doppler fetal heart monitor is provided, which comprises a housing 10 and a probe 20, wherein a contact switch connected with a circuit board 110 is arranged in the housing 10; the probe 20 is provided with an abutting column 210 towards one end of the inner side of the shell 10, the side of the probe 20 towards the circuit board 110 is provided with the abutting column 210, the probe 20 is connected with the shell 10 in a sliding manner along the axis direction of the shell 10, and the abutting column 210 is driven to slide to abut against or be far away from the contact switch 120 so as to open or close the probe 20.

That is, the probe 20 is configured to be in an active state and an inactive state under the switching of the contact switch 120. In the operating state, the probe 20 is pressed to retract toward the inside of the housing 10 and drives the abutment post 210 to abut and trigger the contact switch 120, so that the probe 20 is in the operating state. In the non-operating state, the contact post 210 is spaced from the contact switch 120.

Specifically, the contact switch 120 may be disposed on the circuit board 110, or may be electrically connected to the circuit board 110 and then connected to the housing 10, which is not limited herein.

It should be noted that, when the probe 20 is coated with the couplant, the probe 20 is in the non-working state, and after the probe 20 is placed on the belly of the user and pressed, the abutment post 210 abuts against the contact switch 120 to open the probe 20, so that the unstable touch caused by touching the skin to open the probe 20 is avoided, and the accuracy of monitoring the fetal heart rate by the user is improved. Specifically, the contact switch 120 is used to connect the probe 20 and the circuit board 110, and when the contact post 210 contacts the contact switch 120, the probe 20 communicates with the circuit board 110, and the probe 20 is turned on. That is, when the probe 20 is coated with the coupling agent, the probe 20 is in contact with the skin of the user but is still in a non-working state, and when the force is about 300g by pressing on the bellyband, the contact switch 120 is pressed, the probe 20 is turned on, and at this time, the probe 20 works normally, so that the probe 20 is facilitated to find a stable fetal heart rate on the bellyband of the user.

In one embodiment, the housing 10 has a receiving chamber 140, and a guide baffle 130 is disposed within the receiving chamber 140. The probe 20 is provided with a fitting 30 between the probe 20 and the housing 10, and the probe 20 is slidably fitted to the fitting 30 in the axial direction of the housing 10.

The elastic member 50 may be a spring, an elastic rubber ring, or the like, and is not limited thereto. The springs are illustrated here, but are not limited thereto.

One end of the elastic member 50 is disposed in the annular clamping groove 420, and the annular clamping groove 420 can play a role in installation and guiding on the one hand, and avoid deformation of the elastic member 50 in the axial direction in an elastic compression state. The clamping protrusion 131 has a uniform action on the annular clamping groove 420, and can also have a clamping and guiding action, and will not be described in detail herein.

In one embodiment, the guide baffle 130 is provided with at least one limiting hole 132; one end of the connecting piece 40 is fixedly connected with the probe 20, the other end extends towards the guide baffle 130 to form at least one limiting column 430, the limiting column 430 penetrates through the limiting hole 132 and is provided with a stop portion 431 at one side away from the probe 20, and the stop portion 431 is used for clamping the connecting piece 40 so as to prevent the connecting piece 40 from being separated from the guide baffle 130.

The limiting post 430 is provided to limit the limit operating position of the connector 40, so as to prevent the probe 20 from being elastically separated from the housing 10 in the elastic recovery state of the elastic member 50.

The stop 431 extends radially towards the housing 10, whereby the stop 431 can abut against the surface of the guide baffle 130 when the connection post moves axially towards the housing 10, thereby avoiding the connection piece 40 from disengaging the guide baffle 130 when moving axially along the housing 10.
