2 . The medical device of claim 1 , wherein the first inclined track section is substantially helical such that, in use, the first inclined track section guides the medicament vial to roll along a substantially helical path.

3 . The medical device of claim 1 , wherein the track comprises a plurality of discrete track sections, the plurality of discrete track sections including the first track section, wherein the plurality of discrete track sections are arranged such that the medicament vial is guided to roll along each track section of the plurality of discrete track sections sequentially.

4 . The medical device of claim 3 , wherein the plurality of discrete track sections are vertically stacked such that the plurality of discrete track sections guide the medicament vial to roll in a substantially zigzagging path.

5 . The medical device of claim 3 , wherein the inclined first track section is configured to guide the medicament vial to roll along a substantially straight first path in a first direction, and

wherein the plurality of discrete track sections further comprises an inclined second track section that is configured to guide the medicament vial to roll along a substantially straight second path in a second direction that is different to the first direction.

6 . The medical device of claim 5 , wherein, when the medical device is in use, a horizontal component of the first direction is in a substantially opposite direction to a horizontal component of the second direction.

7 . The medical device of claim 1 , wherein the first track section comprises a support surface along which the medicament vial is guided to roll, wherein the support surface is undulating.

8 . The medical device of claim 1 , wherein the first lateral guide wall is configured to retain the medicament vial on the track as the medicament vial rolls along the track.

9 . The medical device of claim 8 , wherein the track comprises a support surface along which the medicament vial is guided to roll, wherein the first lateral guide wall is arranged along a first edge of the support surface.

10 . The medical device of claim 9 , wherein the second lateral guide wall is configured to retain the medicament vial on the track as the medicament vial rolls along the track, wherein the second lateral guide wall is arranged along a second edge of the support surface that is opposite the first edge of the support surface.

11 . The medical device of claim 1 , wherein the track comprises a terminal track section configured to hold the medicament vial after the medicament vial has ceased rolling along the track, wherein the terminal track section comprises a stopping element configured to inhibit further rolling of the medicament vial.

12 . The medical device of claim 1 , wherein the track is configured such that the medicament vial can continuously roll along the track for between five and sixty seconds.

13 . A system comprising:

a medicament vial containing a medicament, the medicament comprising a lyophilized drug and a diluent, the medicament vial comprising a cylindrical body extending along a longitudinal axis and defining a reservoir for containing the medicament; and

a medical device for mixing the medicament contained within the medicament vial, the medical device comprising a track configured to support the medicament vial, the track comprising an inclined first track section arranged such that, in use, the medicament vial can roll along the track to mix the medicament contained within the medicament vial, the track having a width that corresponds to a height of the medicament vial, the track comprising a first lateral guide wall and a second lateral guide wall configured to inhibit a user from placing a medicament vial having a greater height than the width of the track into the medical device; and

a housing containing the track and comprising a plurality of entry apertures spaced apart from each other, the plurality of entry apertures comprising a first entry aperture arranged on a horizontal top wall of the housing and a second entry aperture arranged on a vertical side wall of the housing, wherein the plurality of entry apertures are configured to selectively provide access to the track according to a size and orientation of the medicament vial, wherein each entry aperture of the plurality of entry apertures allows the medicament vial to be positioned onto a different corresponding position on the track.

14 . A method for using a medical device for mixing a medicament contained within a medicament vial, the medicament vial comprising a cylindrical body extending a longitudinal axis and defining a reservoir for containing the medicament, the medicament comprising a lyophilized drug and a diluent, the medical device comprising a track configured to support the medicament vial, the track comprising an inclined first track section arranged such that, in use, the medicament vial can roll along the track to mix the medicament contained within the medicament vial, the track having a width that corresponds to a height of the medicament vial, the track comprising a first guide wall and a second lateral guide wall configured to inhibit a user from placing a medicament vial having a greater height than the width of the track into the medical device, the medical device comprising a housing containing the track and comprising a plurality of entry apertures spaced apart from each other, the plurality of entry apertures comprising a first entry aperture arranged on a horizontal top wall of the housing and a second entry aperture arranged on a vertical side wall of the housing, wherein the plurality of entry apertures are configured to selectively provide access to the track according to a size and orientation of the medicament vial, wherein each entry aperture of the plurality of entry apertures allows the medicament vial to be positioned onto a different corresponding position on the track the method comprising:

causing the medicament vial to roll along the track of the medical device to mix the medicament contained within the medicament vial.

15 . The method of claim 14 , further comprising positioning the medicament vial at an initial position on the track, wherein causing the medicament vial to roll along a track of the medical device to mix the medicament contained within the medicament vial comprises releasing the medicament vial at the initial position on the track such that the medicament vial rolls along the track to mix the medicament.
