Tool and method for diagnosing premature rupture of membrane by continuous monitoring

Abstract

The invention relates to a tool and a method for diagnosing premature rupture of a membrane by continuous monitoring, which are applicable to household. The tool consists of an upper isolation filter layer, a medium testing system and a lower absorption layer, wherein the testing system consists of an A-type solid-phase vector containing urease and pH indicator and a B-type solid-phase vector containing the pH indicator. The diagnosing method comprises the following steps that: when fluid from the lower body simultaneously soaks two solid-phase vectors, and color development on the A-type solid-phase vector and the B-type solid phase vector has differences, the fluid is urine; and when the color development and color gradation on the A-type solid-phase vector and the B-type solid-phase vector are completely same, the fluid is amniotic fluid. The tool and the method have the advantages of simple operation, higher sensitivity and specificity, continuous detection of discontinuous leakage of the amniotic fluid and real-time property.

Description

Technical field: The invention relates to a non-invasive continuous monitoring premature rupture of membranes diagnostic tool and a diagnostic method suitable for home use. Background technique: Premature rupture of membranes (PROM) is defined as the rupture of membranes before labor, and its incidence rate is 2.7%-17%. Premature rupture of membranes can induce premature labor and increase the chance of intrauterine infection and puerperal infection. For those who gave birth 48 hours after rupture of the membranes, the maternal infection rate was 5%-20%, the sepsis rate was 1:145, and the maternal mortality rate was 1:5500. Fetal aspiration of infected amniotic fluid can cause pneumonia and fetal distress. Increased chance of umbilical cord prolapse. The closer to the full term of pregnancy, the higher the rate of labor signs after rupture of the membranes. Although early detection of premature rupture of membranes has very important clinical significance, it is general...

Problems solved by technology

In summary, currently commonly used diagnostic methods are either inaccurate, highly invasive, or both, and none of these methods allow for continuous real-time monitoring
