摘要： The invention relates to a microfluidic sensing device (1), for conducting measures on liquid samples, comprising a housing (2) having:
- a first opening (12) defining an inlet and/or an outlet for a liquid sample,
- a detection chamber (16) comprising an electrochemical sensor (32),
- a first microfluidic path (14) connecting the first opening (12) to the detection chamber (16), such that the detection chamber (16) can be filled in with the liquid sample,
- a second opening (20) designed so as to allow the application of a negative and/or positive pressure within the housing (2),
- a second microfluidic path (18) connecting the second opening (20) to the detection chamber (16),
- a third opening (28) designed so as to allow the application of a negative and/or positive pressure within the housing (2),
- a third microfluidic path (26) connecting the third opening (28) to the first microfluidic path (14), and
- a waste chamber (22) arranged in the second microfluidic path (18).

摘要： The invention relates to a medical device (1) for trachea pressure measurement comprising a tracheal tube defining an inner surface (12a) and an outer surface (12b) and having a proximal end (1a) and a distal end (1b), configured to be inserted at least partially into the trachea of a subject or animal to deliver respiratory gases to the subject.
The medical device comprises at least one capacitive pressure sensor (20) arranged at said distal end (1b).
