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.
Claims26
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,
- wherein the indicator unit is adapted to monitor and not control fluid flow through the patient attachment unit.
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;
- wherein the indicator unit is adapted to be detachably coupled to the patient attachment unit;
- and
- wherein the indicator unit is adapted to monitor and not control fluid flow through the patient attachment unit.
A method of using a fluid medicament delivery device, the method including the steps of:
- providing 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;
- providing a separate indicator unit comprising a sensing element adapted to detect pressure in the fluid channel via pressure transmitted through at least one of a fluid and a gel, wherein the indicator unit is adapted to monitor and not control fluid flow through the patient attachment unit;
- and
- detachably coupling the indicator unit to the patient attachment unit.
