Embodiment 1
[0038] See figure 1 As shown, in this embodiment, a miniaturized upper gastrointestinal dynamic pH impedance monitoring device includes a pH impedance sensing electrode 1 , a medical catheter 2 , a pH impedance recorder 3 and a background terminal 4 . The background terminal 4 is a PC with a wireless receiver or a mobile communication device. The pH impedance sensing electrode 1 is arranged at the inner front end of the medical catheter 2 , and the pH impedance sensing electrode 1 is connected to the pH impedance recorder 3 through the lead wire 5 arranged in the medical catheter 2 .
[0039] Figure 2 to Figure 7Shown is the schematic diagram of the structure of the pH impedance recorder. The pH impedance recorder 3 includes a main body 3-1 with a box-like structure, and battery compartments 3-3 in which batteries 3-2 are embedded are respectively provided on both sides of the main body 3-1. The main body 3-1 is provided with a battery lock mechanism 3-4. The battery lock ...
