The present invention relates to a tracheostomy valve (100) configured to be in fluid communication with a patient's trachea. The valve comprising a hollow valve body (1), a flexible membrane (7) adapted to work as a check valve opening the valve when the patient inhales and sealingly closing the valve when the patient exhales, and a cap (4) with at least one through hole (4c) making the cap fenestrated. The hollow valve body having a through hole forming a passageway (20) for fluid extending between an inner end (1a) being an outlet of the hollow valve body and an outer end (1b) being an inlet of the hollow valve body. The fenestrated cap (4) being configured to be detachably attached to the outer valve body end (1b), and the inner valve body end (1a) is configured to be in fluid communication with the patient's trachea.本發明係關於一種氣管切開術閥（100），其經組態以與一患者之氣管流體連通。該閥包含：一中空閥體（1）；一可撓性膜片（7），其經調適以充當一止回閥，該止回閥在該患者吸氣時打開該閥且在該患者呼氣時密封地關閉該閥；及一罩蓋（4），其具有使該罩蓋有孔之至少一個穿孔（4c）。該中空閥體具有一穿孔，該穿孔形成在為該中空閥體之一出口的一內部末端（1a）與為該中空閥體之一入口的一外部末端（1b）之間延伸的用於流體之一通路（20）。有孔罩蓋（4）經組態而以可拆卸方式附接至外部閥體末端（1b），且內部閥體末端（1a）經組態以與該患者之氣管流體連通。
