Abstract
A fluid medicament delivery device includes a patient attachment unit and a separate indicator unit. The patient attachment unit includes a housing and a fluid channel located therein, wherein at least a portion of the fluid channel includes a flexible member substantially coterminous with the housing. The separate indicator unit is adapted to be detachably coupled to the housing of the patient attachment unit and includes a first sensing element for contacting the flexible member when the indicator unit is coupled to the housing to sense a flexure of the flexible member.

21. A fluid medicament delivery device comprising:
-
a patient attachment unit comprising a housing and a fluid channel located therein, wherein at least a portion of the fluid channel comprises a flexible member; and a separate indicator unit adapted to be detachably coupled to the housing of the patient attachment unit, the indicator unit comprising a first sensing element adapted to detect pressure in the fluid channel via pressure transmitted through at least one of a fluid and a gel due to deflection of the flexible member. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)

39. A method of monitoring pressure within a fluid channel of a patient attachment unit of a fluid medicament delivery device, the method comprising:
-
measuring a pressure of fluid within the fluid channel across a flexible member of the fluid channel using a first sensing element disposed in a separate indicator unit; wherein the pressure of fluid within the channel is transmitted to the first sensing element in the indicator unit via at least one of a fluid and a gel; and wherein the indicator unit is adapted to be detachably coupled to the patient attachment unit. - View Dependent Claims (40, 41, 42, 43, 44, 45)
