Abstract

The invention discloses a low-power-consumption small-sized in-vivo implantation type gastric physiological parameter monitoring device and method. The method comprises the steps that introgastric pressure conduction is completed by applying a specialized pressure sensing system, gastric myoelectricity conduction is completed by means of a specialized electrode cable, stomach muscle contractilityconduction is completed by means of a stain pressure receptor, core temperature conduction, low-power-consumption signal collection and wireless receiving and dispatching are completed by means of a specialized temperature receptor, wireless receive conditioning of signals is completed through an in-vitro signal data receiving system, and data storage analysis is conducted on a signal data processing and analyzing system through an interface module. Accordingly, related parameters such as the introgastric pressure, gastric myoelectricity, stomach muscle contractility and core temperature can be monitored safely, stably and directly for a long time in a natural physiological status, and display, storage and printout of the related parameters are completed; the device is widely applied to pharmacology, pathology and pharmacological test, effectively applied to research of gastrointestinal diseases and judgement of the related therapeutic drug curative effect and applied to other researchfields.

Description

technical field [0001] The invention relates to the technical field of biomedical engineering, in particular to a device and method for monitoring gastric physiological parameters implanted in a body with low power consumption and small volume. Background technique [0002] At present, there is a single measurement parameter for the measurement of gastric physiological parameters (only one of the parameters of intragastric pressure, gastric myoelectricity and gastric muscle contraction can be measured), and it is impossible to stably monitor multiple gastric physiological parameters for a long time . [0003] The direct measurement of intragastric pressure, gastric myoelectricity, gastric muscle contractility and body temperature can truly and effectively obtain relevant parameters of gastric physiology and long-term monitoring. Domestic research institutions have carried out a lot of research on the construction and functions of implantable systems, but there are still no ...
