Patient Monitor IoT Development

I have an ESP32CAM, a power supply, one microphone, one speaker, one body temperature sensor, one blood oximeter sensor, one DHT22 sensor, one IR sensor, one servo motor, and one mini water pump, I want to make a lot, of remote patient monitoring system in which, through ESP32CAM there is a speaker and microphone are connected using which a patient can communicate with the doctor and the doctor can give instruction to the patient from a mobile phone app the voice get out from the speaker of IoT system in the patient's room and the doctor can watch the patient through ESP32CAM in the phone app and hear patient's voice in his phone and so it is two-way communication between the patient and doctor just patient can not see the doctor just can hear his voice. there are three sensors DHT22, a body temperature sensor, and a blood oximeter sensor connected to the ESP32CAM module which can measure a patient's all important parameters like blood oxygen level, room temperature, and body temperature and send it to the app in doctor's phone, so the doctor can monitor the patient, and also there is mini water pump is connected to the ESP32CAM module and the controls are in the app in doctor's phone.
