For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0027] like Figures 1 to 4 As shown, a fetal heart rate monitor includes a fetal heart rate monitor body, a first metal electrode, a second metal electrode and a finger-touch metal electrode assembly.

[0028] The fetal heart rate monitor mainly includes an ultrasonic probe, on which an ultrasonic transducer 1 is installed. The ultrasonic transducer 1 can collect the fetal heart rate through the ultrasonic Doppler principle to detect the fetal heart rate.

[0029] The first metal electrode 2 and the second metal electrode 3 are respectively mounted on the human body contact surface of the ultrasound probe of the fetal heart rate monitor body, and the finger-touching metal electrode assembly 15 is mounted on the side of the fetal heart rate monitor body.

[0030] In traditional ECG monitors, the most common and simplest is a single-lead ECG consisting of three metal electrode sheets. Therefore, based on the principle of the ECG monitor, a first metal electrode 2, a second metal electrode 3 and a finger-touch metal electrode assembly 15 are set on the fetal heart monitor to form three metal electrode sheets of the ECG monitor, wherein the potential difference between the first metal electrode 2 and the finger-touch metal electrode assembly 15 is used as a differential signal to collect the mother's heart rate. At the same time, the second metal electrode 3 at the bottom of the ultrasound probe is used as the right leg driving metal electrode to invert and amplify the common-mode signal and input it into the human body to suppress common-mode interference and improve the CMRR of the system.

[0031] Through the above device, the fetal heart rate and the mother's heart rate can be measured simultaneously, and the common mode interference of the human body can be effectively suppressed.

[0032] Since the fetal heart monitor needs to be moved during detection, the touch of the finger part is prone to be intermittent, which affects the accuracy of the detection. Therefore, this embodiment also proposes that the finger touches the metal electrode assembly. The finger is clamped by touching the metal electrode assembly to ensure that the finger touch is reliable during detection, thereby overcoming the problem of inaccurate detection caused by unreliable finger touch.

[0033] The finger-touch metal electrode assembly 15 includes a first finger electrode clip 18 , a second finger electrode clip 20 , a first shell 16 , a second shell 17 and a torsion spring 19 .

[0034] The first finger electrode clip 18 and the second finger electrode clip 20 together form a third metal electrode.

[0035] The first shell 16 is rotatably connected to the second shell 17 , and the torsion spring 19 is connected to the first shell 16 and the second shell 17 respectively. Under the elastic force of the torsion spring 19 , the first shell 16 and the second shell 17 can maintain an inwardly clamped state.

[0036] The first finger electrode clip 18 is mounted on the first housing 16 , and the second finger electrode clip 20 is mounted on the second housing 17 . During detection, the torsion spring 19 causes the first finger electrode clip 18 and the second finger electrode clip 20 to clamp the finger.

[0037] During detection, the first finger electrode clip 18 and the second finger electrode clip 20 clamp the finger together, so that even if the fetal heart rate monitor is moved, it can be ensured that the finger is in reliable contact with the first finger electrode clip 18 and / or the second finger electrode clip 20.

[0038] The first shell 16 and the second shell 17 are both arc-shaped, which can better clamp the fingers.

[0039] The first finger electrode clamp 18 and the second finger electrode clamp 20 are both arc-shaped, which can better clamp the fingers.

[0040] The first housing 16 and the second housing 17 are connected via a rotating shaft, and the torsion spring 19 is installed on the rotating shaft.

[0041] The rotating shaft may be a cylindrical body 161 integrally formed on the first shell 16 .

[0042] The first housing 16 is provided with a first groove, the second housing 17 is provided with a second groove 171 , the first finger electrode clip 18 is embedded in the first groove, and the second finger electrode clip 20 is embedded in the second groove 171 .

[0043] The fetal heart rate monitor body includes an ultrasonic probe cover 13 , and the first metal electrode 2 and the second metal electrode 3 are respectively mounted on the bottom surface of the ultrasonic probe cover 13 .

[0044] The finger-touching metal electrode assembly 15 is mounted on the hand-held portion of the fetal heart rate monitor body.

[0045] The finger-touching metal electrode assembly 15 is installed in the middle of the handle of the fetal heart monitor body.

[0046] The finger-touching metal electrode assembly 15 is installed vertically so as to better match the finger.

[0047] The first metal electrode 2, the second metal electrode 3 and the ultrasonic transducer 1 of the ultrasonic probe of the fetal heart rate monitor body are located in the same plane. The first metal electrode 2, the second metal electrode 3 and the ultrasonic transducer 1 are all installed on a probe plane. The coupling agent, water, etc. applied when using ultrasound can just humidify the metal electrodes to enhance the signal.

[0048] The fetal heart rate monitor body also includes a rear shell 6 , a speaker 7 , a speaker cover 8 , a display screen mainboard assembly 9 , a silicone button 10 , a front shell 11 , a lens 12 and a battery 14 .

[0049] The finger-touching metal electrode assembly 15 is vertically installed between the rear shell 6 and the front shell 11, and is easy to assemble.

[0050] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
