A medicated module (4) for an injection system to co-deliver at least two medicaments is disclosed where a primary delivery device containing a primary medicament accepts a medicated module (4) containing a single dose of a secondary medicament and where both medicaments are delivered through a hollow needle (3). The medicated module (4) is user selectable so that it will deliver a priming dose of a primary medicament or both the primary and secondary medicaments. The module (4) also contains a needle guard (42) that locks after dose delivery. The needle guard (42) prevents accidental needle sticks before and after an injection. A locking collar (66) rotates during use as an inner protrusion (12) follows three paths (14, 15, 16) of a track (13) located on the outer surface of a body housing (10). When the inner facing protrusion (12) is in the third path (16), it encounters a hard stop and a rotational bias that locks the guard (42) from further retraction and thus covers the sharp distal end of the needle (3).

The invention relates to improved methods and systems for computationally efficient optimization of radiation dose delivery. The optimization involves determining an improved form of objective function to be used for mapping radiotherapy beams to a patient body volume having at least one target volume and at least one non-target volume. The objective function has a first term related to the at least one target volume and a second term related to the at least one non-target volume. The optimization further involves determining a minimum of the objective function, whereby beams mapped so as to pass through the at least one non-target volume are limited such that the second term is zero only if the weights of beamlets passing through the at least one non-target volume are zero. This limit helps to avoid the occurrence of negative beam weights, thereby facilitating computationally efficient determination of the minimum of the objective function using matrix inversion. Following the optimization, radiotherapy is delivered based on the determined minimum of the objective function.

A medicated module (4) for an injection system to co-deliver at least two medicaments is disclosed where a primary delivery device containing a primary medicament accepts a medicated module (4) containing a single dose of a secondary medicament and where both medicaments are delivered through a hollow needle (3).

Instead, a biasing member (48) automatically activates the reservoir (22) when the needle guard (42) is retracted. The needle guard (42) prevents accidental needle sticks before and after an injection, and locks after dose delivery.

The invention relates to methods and systems for computationally efficient optimization of radiation dose delivery that involve determining an objective function to be used for mapping radiotherapy beams to a patient body volume having at least one target volume and at least one non-target volume. The objective function has a first term related to the at least one target volume and a second term related to the at least one non-target volume. The second term is zero only if the weights of beamlets mapped so as to pass through the non-target volume(s) are zero. The second term helps to avoid the occurrence of negative beam weights, thereby facilitating computationally efficient optimization using matrix inversion. An optimal set of weights of beamlets is determined using the objective function. Radiotherapy is delivered based on the determined optimal set of weights.

A drug delivery device (1; 100; 200) comprising a housing (2; 102; 201, 202), a dose setting mechanism operable to set a dose to be delivered from a variable volume reservoir, and a dose delivery structure (60; 160; 260) activatable to expel a set dose. The dose setting mechanism comprises a dose indicating structure (40; 140; 240) for indicating a size of the set dose. The dose indicating structure (40; 140; 240) is coupled with the dose delivery structure (60; 160; 260) during expelling of the set dose and moved relative to the housing (2; 102; 201, 202) to a zero dose indicating position.
