Problems solved by technology

A single battery guarantees that 24-hour sampling can meet the basic requirements of 24-hour pH-impedance detection, but has the following defects: 1. The requirement of low power consumption limits the freedom of signal collection to a certain extent: such as sampling rate and collected The characteristic frequency of the impedance
2. The use of dry batteries limits the further miniaturization of the product, thus affecting the comfort of the wearer to a certain extent
3. The standby time of a single battery for 1-2 days limits the continuous recording time of pH impedance

Abstract

The invention discloses a miniaturized upper gastrointestinal dynamic pH impedance monitoring device. The miniaturized upper gastrointestinal dynamic pH impedance monitoring device comprises a pH impedance sensing electrode, a medical catheter, a pH impedance recorder and a background terminal. The pH impedance sensing electrode is located at the front end of the interior of the medical catheter and is connected to the pH impedance recorder via a lead wire arranged in the medical catheter. The pH impedance recorder is internally provided with an acquisition front end circuit, a controller, a wireless receiving and dispatching module and a power management module. The power management module includes a power management chip LTC4413, a main power battery BT1 and a backup battery BT2, whereinthe power management chip LTC4413 selects one, with higher voltage, of the main power battery BT1 and the backup battery BT2 as a load to provide the power. The miniaturized upper gastrointestinal dynamic pH impedance monitoring device adopts a battery hot plug mode to keep the device working for a long time, gets rid of the limitation of battery electric quantity and device power consumption, and achieves uninterrupted pH impedance measurement so as to further miniaturize products and battery sizes and further optimize the wearing feelings of wearers.

Description

technical field [0001] The invention relates to a miniaturized upper digestive tract dynamic pH impedance monitoring device. Background technique [0002] At present, 24-hour pH-impedance combined detection has become the standard test for the diagnosis of gastroesophageal reflux disease. It is mainly by inserting a catheter carrying a pH sensor and an impedance electrode into the esophagus through the human nasal cavity, and the other end of the catheter is connected to a collector. Due to the need for accurate diagnosis, on the one hand, data collection needs to have a high sampling frequency, and on the other hand, data needs to be recorded for at least 24 hours. In addition, the data acquisition instrument needs to be carried around and affect the wearer's daily life as little as possible. These requirements lead us to pursue products that are both miniaturized and low power consumption. At this stage, many pH impedance joint detection devices use AA batteries to ensu...
