Medical treatment of severe blood loss during labor is crucial, and the early warning indicator of postpartum hemorrhage (PPH) is essential for labor medical treatment. Measurement of blood loss conventionally looks dirty, reluctant, and less hygienic since some of the blood might be spilled out in the maternity bed, while commercially existing pads have low blood absorption capacity. A new design composite pad composed of absorbent materials, including cellulose rayon, super absorbent polymer (SAP), and zeolite was fabricated and characterized. The SAP and zeolite show properties as crystalline and amorphous materials, respectively. The surface area of natural zeolite was 19.79 (m/g). The newly fabricated composite pad showed a high blood absorption capacity (>500-600 mL) with a blood absorption rate of 55.56-85.84 mL/min (depending on the blood volume), showing better performance as compared to the commercial pads. These characteristics suggest that the new composite pad could function not only as a sanitary pad but also as an early warning indicator for PPH if the rate and blood volume reach the dangerous category (≥600 mL or at ≥13 mL/min rate).
分娩期间严重失血的医学治疗至关重要，产后出血（PPH）的早期预警指标对分娩医学治疗必不可少。传统的失血量测量看起来既脏又不方便，而且不太卫生，因为部分血液可能会洒在产床上，而市面上现有的护垫血液吸收能力较低。一种由包括粘胶纤维、高吸水性聚合物（SAP）和沸石在内的吸收性材料制成的新型复合护垫被制造出来并进行了特性表征。SAP和沸石分别表现出晶体和非晶体材料的特性。天然沸石的表面积为19.79（平方米/克）。新制造的复合护垫显示出高血液吸收能力（>500 - 600毫升），血液吸收速率为55.56 - 85.84毫升/分钟（取决于血量），与商业护垫相比表现出更好的性能。这些特性表明，如果速率和血量达到危险类别（≥600毫升或以≥13毫升/分钟的速率），这种新型复合护垫不仅可以用作卫生护垫，还可以用作PPH的早期预警指标。
