Regarding claim 24, Helmer/Boyd/Marsh discloses the controlled multidosing delivery device of claim 23 disclose the visual indicator (See claim 23) includes at least window (house opening and translucent window, see claim 23). Helmer/Marsh are silent wherein the window disposed to view a position of a portion of the drive shell within the housing.
Boyd further teaches a window (window [0074]) disposed to view a position of a portion of a drive shell within the housing. ([0074]: “visual feedback regarding dose dispense may optionally be indicated by a graphical status indicator, provided on the drive member 17, which can be viewed through the optional window to the drive member 4' in the main housing 4.”)
Therefore, it would have been obvious for one of ordinary skill in the art before the effective filing date of the claim invention to configure the window of Helmer/Boyd/Marsh to view a position of a portion of the drive shell within the housing implementing the teaching of Boyd ([0070]). The device of Helmer/Boyd /Marsh will have the opening in the housing and the transparent window as modified in claim 23 now configure to see the position of drive shell. The drive shell and transparent window creates a drive scale as previously shown in claim 23 as taught by Marsh ([0134]).

Klintenstedt further teaches a flange (14’) and the clip (50) comprises resilient washes 56.
Therefore, it would have been obvious for one of ordinary skill in the art before the effective
filing date of the claim invention to modify the device of Helmer/Boyd by having a similar flange in the proximal end of barrel 3 of Helmer/Boyd to provide coupling means to the clip taught by Klintensted to secure the syringe components to the distal end of housing allowing large tolerances without affecting the accuracy of the dose delivery ([0053])
Regarding claim 19, Helmer/Boyd/Klintenstedt discloses the controlled multidosing delivery device of claim 17.

However, Helmer/Boyd/Klintenstedt are silent regarding the resilient washer is an elastomer.
Cowe teaches a device (autoinjector 1, Fig 1) comprising a housing (housing 19, Fig 1) and a syringe (syringe barrel 88+ sliding bung 91+ tip of the needle 89). Cowe further teaches an elastomeric washer (cushioning element 47; [0049]: “A cushioning element 47, in the form of an annular washer of elastomeric material is located at the bottom of the cup 43.”)
Therefore, it would have been obvious for one of ordinary skill in the art before the effective
filing date of the claim invention to modify the material of washer of Helmer/Boyd/Klintenstedt to be an elastomeric material. The inherent properties of an elastomeric material will further assist to secure the syringe components to the housing allowing large tolerances without affecting the accuracy of the dose delivery and provide cushioning and protection of the internal components being coupled.
