Abstract

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 (m2/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).

新型沸石基复合垫吸血量大,可用于产后出血早期预警
分娩过程中严重失血的医疗处理至关重要,而产后出血(PPH)的早期预警指标对分娩医疗处理至关重要。传统的失血测量方法看起来很脏、很不情愿,而且由于部分血液可能会溢出产床而不太卫生,而市面上现有的血垫吸血能力较低。我们制作并鉴定了一种由纤维素人造丝、超强吸水聚合物(SAP)和沸石等吸水材料组成的新型设计复合垫。SAP 和沸石分别具有晶体和非晶体材料的特性。天然沸石的表面积为 19.79(m2/g)。新制成的复合垫具有很高的吸血能力(>500-600 mL),吸血速率为 55.56-85.84 mL/min(取决于血量),与商用垫相比性能更好。这些特性表明,新型复合垫不仅可以作为卫生垫使用,而且在吸血率和血量达到危险类别(≥600 mL 或吸血率≥13 mL/min)时,还可以作为 PPH 的预警指标。
