Medicament delivery device
A medicament delivery device is described. The device includes a body having proximal and distal ends defining a longitudinal direction; a needle for injecting medicament into a user and configured to be arranged in an injecting position in which the needle protrudes from the distal end of the body; a cap moveable along the longitudinal direction to be arrangeable in a capped position in which the cap conceals the distal end of the body, and an uncapped position in which at least a portion of the cap is spaced apart from the distal end; and a blocking element. When the cap is in the uncapped position, the blocking element is arrangeable in a first state in which movement of the cap from the uncapped position into the capped position is permitted, and a second state in which movement of the cap from the uncapped position into the capped position is prevented.
1 . A medicament delivery device, comprising:
a body having a proximal end and a distal end defining a longitudinal direction;
a needle for injecting medicament into a user and configured to be arranged in an injecting position in which the needle protrudes from the distal end of the body;
a needle shield assembly receivable inside the body and comprising (i) a needle cover configured to circumscribe at least a portion of the needle, and (ii) a cap insert configured to receive the needle cover;
a cap moveable along the longitudinal direction and arrangeable in a capped position in which the cap conceals the distal end of the body, a first initial uncapped position in which the cap has not previously been in the capped position, and a second subsequent uncapped position in which the cap has previously been in the capped position, wherein when the cap is in the first initial uncapped position and the second subsequent uncapped position, at least a portion of the cap is spaced apart from the distal end of the body; and
a blocking element, wherein when the cap is in the first initial uncapped position, the needle cover inside the body is configured to position the blocking element in a first state in which movement of the cap from the first initial uncapped position into the capped position is permitted, and wherein when the cap is moved from the capped position into the second subsequent uncapped position, the cap is configured to receive the cap insert such that the needle shield assembly is coupled to the cap and removed from the body, causing the blocking element to be arranged in a second state in which movement of the cap from the second subsequent uncapped position into the capped position is prevented.
2 . The medicament delivery device of claim 1 , wherein when the cap is in the capped position, the cap is coupled to the body, and when the cap is in the first initial uncapped position and the second subsequent uncapped position, the cap is decoupled from the body.
3 . The medicament delivery device of claim 1 , wherein the cap is configured to move from the first initial uncapped position in which the cap has not previously been in the capped position, into the capped position, to cause the cap to be coupled to the needle shield assembly.
4 . The medicament delivery device of claim 1 , wherein the needle shield assembly is configured to be movable relative to the body along the longitudinal direction, such that when the needle shield assembly is coupled to the cap, the needle shield assembly and the cap are configured to be movable together relative to the body along the longitudinal direction.
5 . The medicament delivery device of claim 1 , wherein when the cap is in the first initial uncapped position and the needle shield assembly is not coupled to the cap, the blocking element is configured to be in the first state; and wherein when the cap is in the second subsequent uncapped position and the needle shield assembly is coupled to the cap, the blocking element is configured to be in the second state.
6 . The medicament delivery device of claim 1 , wherein when the cap is in the capped position, the cap is configured to form a snap fit connection with the body to couple the cap to the body.
7 . The medicament delivery device of claim 6 , wherein moving the cap from the first initial uncapped position in which the cap has not previously been in the capped position, into the capped position, is configured to cause the cap and the body to be arranged in the snap fit connection.
8 . The medicament delivery device of claim 1 , wherein the blocking element comprises a chamfered surface inclined relative to the longitudinal direction.
9 . The medicament delivery device of claim 1 , wherein the blocking element is coupled to or integrally formed with the body and wherein at least a portion of the blocking element is configured to move in a radial direction that is generally normal to the longitudinal direction, such that when the blocking element is in the first state, said at least a portion of the blocking element is arranged in a radially outward position, and such that when the blocking element is in the second state, said at least a portion of the blocking element is arranged in a radially inward position that is radially inward relative to the radially outward position, relative to a central longitudinal axis of the medicament delivery device; and wherein the blocking element is biased towards the radially inward position.
10 . The medicament delivery device of claim 1 , wherein the medicament delivery device contains the medicament.
