Medicament Delivery Device with Use Indicator
Described is a medicament delivery device comprising a case adapted to hold a container with a medicament and having a needle, a needle sleeve telescopically coupled to the case and having a first extended position relative to the case in which the needle is covered, a retracted position relative to the case in which the needle is exposed, and a second extended position relative to the case in which the needle is covered, a first indicia disposed on the needle sleeve which is visible in the first extended position and the second extended position, and a second indicia disposed on the needle sleeve and not visible in the first extended position and visible the second extended position.
1 . (canceled)
2 . A method comprising:
moving a sleeve relative to a housing of an auto-injector from (i) a first sleeve position in which a first indicia on the sleeve is in a first indica position to indicate a first status of the auto-injector to (ii) a second sleeve position in which the first indicia is in a second indica position to indicate a second status of the auto-injector, the first indicia comprising a first color and being viewable from an exterior of the auto-injector when the first indicia is in the first and second indica positions,
wherein the auto-injector comprises a second indicia axially offset from the first indicia, the second indicia comprising a symbol or graphic of a second color and being viewable from the exterior of the auto-injector at least when the first indicia is in the second indica position.
3 . The method of claim 2 , comprising directly touching the sleeve to move the sleeve from the first sleeve position to the second sleeve position.
4 . The method of claim 2 , wherein the second color is red.
5 . The method of claim 2 , wherein the symbol or graphic of the second indicia is a second symbol or a second graphic, and the first indicia comprises a first symbol or a first graphic.
6 . The method of claim 2 , wherein the first status of the auto-injector represents a pre-use state of the auto-injector.
7 . The method of claim 6 , wherein the second status of the auto-injector represents a post-use state of the auto-injector.
8 . The method of claim 2 , wherein the first indicia extends proximally from a distal edge of the sleeve.
9 . The method of claim 2 , wherein the second indicia is disposed on the sleeve.
10 . The method of claim 2 , wherein an axial length of the first indicia is shorter than an axial length of the sleeve.
11 . The method of claim 2 , wherein the first indicia is disposed on a distal portion of an outer surface of the sleeve.
12 . A method comprising:
moving a sleeve relative to a housing of an auto-injector from (i) a first sleeve position in which a first indicia of the sleeve is in a first indica position to indicate a first status of the auto-injector to (ii) a second sleeve position in which the first indicia is in a second indica position to indicate a second status of the auto-injector, the first indicia comprising a first color and being viewable from an exterior of the auto-injector when the first indicia is in the first and second indica positions,
wherein the auto-injector comprises a second indicia comprising a symbol or a graphic and being viewable from the exterior of the auto-injector at least when the first indicia is in the second indica position.
13 . The method of claim 12 , wherein the first color is green.
14 . The method of claim 13 , wherein the symbol or the graphic of the second indicia has a second color different than green.
15 . The method of claim 14 , wherein the second color is red.
16 . The method of claim 12 , comprising viewing the first and second indicia from the exterior of the auto-injector.
17 . The method of claim 12 , comprising depressing a button at a proximal end of the auto-injector allowing a distal end of a needle of a syringe to be exposed from a distal end of the housing.
18 . The method of claim 17 , comprising after depressing the button, distally moving a plunger relative to the syringe to dispense a medicament from the syringe into an injection site.
19 . The method of claim 18 , wherein the first status of the auto-injector represents a pre-use state of the auto-injector in which the medicament has not been dispensed from the syringe.
20 . The method of claim 19 , wherein the second status of the auto-injector represents a post-use state of the auto-injector in which the medicament has been dispensed from the syringe.
21 . The method of claim 12 , wherein the first status of the auto-injector represents a pre-use state of the auto-injector, and the second status of the auto-injector represents a post-use state of the auto-injector.
