A kind of diaper showing urine acid alkali value include a diaper ontology,One acid base indicator and a sour alkali value comparison table,The diaper ontology include a porous endosexine,The absorbed layer of one waterproof extexine and encapsulating what between the two,There is a transparent window at the waterproof extexine what crotch,The acid base indicator is located between waterproof extexine and absorbed layer,And position is at the transparent window,The acid base indicator is the chemical reagent that can generate different colours variation when touching urine according to the sour alkali degree of the urine,Its medial surface that can be coated directly onto the waterproof extexine,It can also be the litmus paper for detecting sour alkali value,The acid alkali value comparison table is printed on the lateral surface of waterproof extexine,Its color change for being labeled with the acid base indicator and corresponding acid alkali value； The sour alkali value of the urine in diaper just can be easily picked out by outside by above structure system,And then medical staff's record can be facilitated and judge physical condition or the medication situation person of user.一種可顯示尿液酸鹼值的尿布包括一尿布本體、一酸鹼指示劑及一酸鹼值對照表，該尿布本體包含一可透水內表層、一不透水外表層及包封於兩者之間的一吸收層，該不透水外表層於胯部處具有一透明視窗，該酸鹼指示劑設在不透水外表層與吸收層之間，且位在該透明視窗處，該酸鹼指示劑為接觸到尿液時即可依據該尿液的酸鹼程度產生不同顏色變化的化學試劑，其可直接塗佈在該不透水外表層的內側面，亦可以是檢測酸鹼值之石蕊試紙，該酸鹼值對照表印刷在不透水外表層的外側面，其標示有該酸鹼指示劑的顏色變化及所對應之酸鹼值；藉由上述結構係可由外部輕易的便能辨識出尿布中之尿液的酸鹼值，進而可方便醫護人員記錄及判斷使用者的身體狀況或用藥情形者。
