Continuous abdominal wall pressure measuring and monitoring system

Abstract

The invention discloses a continuous abdominal wall pressure measuring and monitoring system. The continuous abdominal wall pressure measuring and monitoring system includes a multi-channel pressure sensing system, a collection and measurement system and a computer, and the multi-channel pressure sensing system is connected with computer with the computer through the collection and measurement system and composed of a strip belt bound on the human abdomen and a plurality of pressure sensors fixed on the strip belt; the collection and measurement system is composed of a pressure-voltage conversion module, a signal amplification module and a multi-channel data collection-sending module which are sequentially connected, wherein the output end of each pressure sensor is connected with the input end of the pressure-voltage conversion module. The continuous abdominal wall pressure measuring and monitoring system is simple in structure, convenient to operate, capable of accurately obtaining a result about the abdominal pressure changes of a patient, and suitable for industrialized production and market popularization.

Description

technical field [0001] The invention relates to a continuous abdominal wall pressure measurement and monitoring system, which belongs to the field of continuous monitoring of abdominal muscle state. Background technique [0002] Intra-abdominal pressure (IAP) is the pressure in the closed abdominal cavity under stable conditions, mainly generated by the hydrostatic pressure of the abdominal viscera. Normally, IAP is maintained at about 0mmHg (1mmHg=0.133kPa). Critically ill patients Fluctuation in 5 ~ 7mmHg. [0003] The latest guidelines issued by the World Society of the Abdominal Compartment Syndrome (WSACS) define IAH as persistent or recurrent IAP ≥ 12 mmHg. Abdominal compartment syndrome (ACS) should be diagnosed when IAP is consistently higher than 20 mmHg and new organ failure occurs, regardless of whether abdominal perfusion pressure (APP) <60 mmHg occurs. IAH and ACS can cause extensive harm to the body. When IAP is pathologically increased, vascular compress...

Problems solved by technology

The disadvantage of intermittent measurement of intravesical pressure is that it can only reflect the pressure at the measurement point and cannot reflect changes in intra-abdominal pressure in real time. For real-time changes in intravesical pressure, there is a lack of early warning mechanism, which may lead to untimely detection of abdominal hypertension. Early diagnosis and Untimely treatment will increase the adverse consequences of intra-abdominal hypertension and increase the incidence of organ failure and mortality
