● This instrument is a portable device. Please be careful to avoid falling and collision during use, and pay attention to the safety of the instrument and personnel. Doppler fetal heart rate monitor is a device for checking fetal heart rate in a short time. It is not suitable for long-term monitoring of the fetus and cannot replace traditional fetal heart rate monitors. Monitoring and diagnosis shall prevail. ● Do not use when the probe breaks or bleeds in contact with the skin. Dermatological patients should disinfect the probe after use. Please keep it properly after use to keep the product clean and tidy. ● The surface of the probe in contact with the patient may cause discomfort to the patient due to biocompatibility issues. Fetal Doppler may cause skin irritation to the user. If the patient feels unwell or allergic, they should stop using it immediately and seek medical advice if necessary. ● We recommend that the ultrasound irradiation time for pregnant women should be shortened as much as possible under the premise of meeting the clinical needs. ● When using this instrument, please use the earphones configured by the manufacturer. Using other headphones may result in lower volume or change in sound quality, making the experience less enjoyable. ● This instrument cannot be used with high-frequency surgical equipment, with fetal monitors, or with two or more fetuses at the same time. Please use this instrument for monitoring alone. ● This instrument is easily affected by portable or mobile radio frequency communication equipment, such as mobile phones, during operation.
