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.
Claims24
A fluid medicament delivery device comprising:
- a disposable patient attachment unit adapted to deliver a fluid medicament contained therein to a patient;
- and
- a separate reusable indicator unit, wherein the indicator unit is:
- adapted to:
- (i) detachably connect to the patient attachment unit, (ii) notify the patient when to disconnect the indicator unit from the patient attachment unit, and (iii) connect to a different patient attachment unit;
- and
- structurally incapable of changing a flow rate of the medicament.
A method of using a medicament delivery device, the method comprising the steps of:
- connecting a reusable indicator unit to a disposable patient attachment unit adapted to deliver a fluid medicament contained therein to a patient, wherein the indicator unit is not adapted to change a flow rate of the medicament;
- receiving a notification from the indicator unit that it is to be disconnected from the patient attachment unit;
- disconnecting the indicator unit from the patient attachment unit;
- and
- connecting the indicator unit to a different patient attachment unit.
A method of operating a medicament delivery device comprising a disposable patient attachment unit adapted to deliver a fluid medicament contained therein to a patient, and a separate reusable indicator unit, wherein the indicator unit is not adapted to change a flow rate of the medicament, the method comprising the steps of:
- determining that an event has occurred, the event selected from the group consisting of:
- (i) the patient attachment unit has experienced as occlusion event, (ii) the patient attachment unit is functionally depleted of medicament, and (iii) a component of the indicator unit has functionally failed;
- and
- notifying the patient to disconnect the indicator unit from the patient attachment unit.
