1. An apparatus for use in setting the dose of a syringe of the type having two parts which are rotatable relative to one another to set the size of a dose, said apparatus comprising:
- a housing including a receiving portion for detachably securing a syringe of the foregoing type while setting a dose, wherein such syringe may thereafter be released from such receiving portion in order to inject the set dose, a first engagement member coupled to the housing and positioned to engage one of the two parts of such syringe when the syringe is secured in the receiving portion, a second engagement member coupled to the housing and positioned to engage the other of the two parts of such syringe when the syringe is secured in the receiving portion, wherein at least one of the engagement members is moveable relative to the housing such that the engagement members are movable relative to one another responsive to relative rotatation of the two parts of such syringe;
a detector means coupled to at least one of the engagement members for detecting relative movement of the engagement members; and
an information providing means coupled to the detector means for providing information relating to the amount of relative movement of the engagement members.

19. The combination of a syringe having two mutually rotatable parts for setting a dose, and an apparatus for use while setting a dose, wherein said apparatus comprises:
-
a housing including a receiving portion in which the syringe is detachably secured for setting a dose, wherein the syringe may be released from such receiving portion after setting the dose in order to inject the set dose, a first engagement member coupled to the housing and positioned to engage one of the two parts of the syringe, a second engagement member coupled to the housing and positioned to engage the other of the two parts of such syringe, wherein at least one of the engagement members is moveable relative to the housing such that the engagement members are movable relative to one another responsive to relative rotatation of the two parts of such syringe;
a detector means coupled to at least one of the engagement members for detecting relative movement of the engagement members; and
an information providing means coupled to the detector means for providing information relating to relative movement of the engagement members. - View Dependent Claims (20, 21, 22)
