The system comprises a mast connected to a base, wherein the mast is angled with respect to the base and from which any number of medical components is supported. The device geometry and connections ensure the device is extremely stable and tip-resistant. Also provided are oxygen tank holders to reliably and conveniently hold oxygen tanks and power management systems that reliably provide electrical power without impacting device performance or mobility. The device is deployable to permit conversion between a compact storage configuration and a stable deployed configuration. ## Claims ### Claim 1 A mobility assistance device comprising: a mast that is a central pole angled with respect to horizontal; a first base leg connected to the mast; a second base leg connected to the mast; wherein the first and second base legs form an open two-sided base footprint having a triangle or truncated triangle footprint; wherein the mast and the base footprint form a mast angle having an acute angle so that the mast extends within a region that vertically extends from the two-sided base footprint; a first wheel connected to the first base leg; a second wheel connected to the second base leg; a third wheel connected to a vertex region, wherein the vertex region is formed by one end of each of the first and second base legs connected to a bottom end of the mast; a mobility handle connected to the mast; an oxygen tank holder comprising: an upper tank holder connected to the mast for coupling with an upper portion of an oxygen tank; a lower tank holder connected to the first or the second base leg for coupling with a base portion of the oxygen tank wherein the lower tank holder is configured to position the oxygen tank on the first base leg or on the second base leg; a pole connected to the mast for securing a medical component, the mast having a top end and an outer surface extending between the top end and the bottom end, wherein the pole has a longitudinal axis that is separated from the outer surface of the mast by a separation distance and is connected to the mast at the mast top end and the mast bottom end; an outlet strip mount for securing an outlet strip; a power cord management system comprising a first cord management bracket and a second cord management bracket connected to the mobility assistance device for storing a cord of the outlet strip; and wherein the outlet strip mount is connected to the pole; and the power cord management system is connected to the mast. ### Claim 2 (depends on 1) The device of claim 1, wherein the upper oxygen tank holder comprises an arm for securing the oxygen tank at an oxygen tank axial location. ### Claim 3 (depends on 2) The device of claim 2, wherein the arm is a clasp. ### Claim 4 (depends on 2) The device of claim 2, wherein the arm is a loop having an internal passage configured to receive the oxygen tank. ### Claim 5 (depends on 4) The device of claim 4, wherein the loop is rotationally positionable relative to the first and second base legs to receive the oxygen tank over the first base leg or the second base leg. ### Claim 6 (depends on 1) The device of claim 1, wherein the lower tank holder comprises a receiving surface and a circumferential lip for receiving a bottom surface of the oxygen tank. ### Claim 7 (depends on 6) The device of claim 6, wherein the circumferential lip is non-continuous. ### Claim 8 (depends on 1) The device of claim 1, further comprising a second lower tank holder, wherein the lower tank holder is connected to the first base leg and the second lower tank holder is connected to the second base leg. ### Claim 9 (depends on 1) The device of claim 1, wherein the lower tank holder is reversibly connected to the first base leg or the second base leg, so that the oxygen tank is supported by the first base leg or the second base leg. ### Claim 10 (depends on 1) The device of claim 1, further comprising the oxygen tank, wherein the oxygen tank is in an upright position and supported by the first base leg or the second base leg. ### Claim 11 (depends on 10) The device of claim 10, wherein the oxygen tank is a D cylinder (4.38″ diameter and 16.5″ height) or an E cylinder (4.38″ diameter and 25.5″ height). ### Claim 12 (depends on 1) The device of claim 1, wherein each of the base legs has a base leg length, wherein the oxygen tank holder is configured to secure the oxygen tank to a longitudinally-defined portion of the first or second base leg, the longitudinally-defined portion extending from the mast to about half of the base leg length. ### Claim 13 (depends on 1) The device of claim 1, wherein the upper oxygen tank holder is connected to the mast by an accessory module. ### Claim 14 (depends on 13) The device of claim 13, wherein the upper oxygen tank holder is rotably connected to the mast by the accessory module. ### Claim 15 (depends on 1) The device of claim 1, wherein: the mobility handle is a height adjustable mobility handle connected to the mast, wherein the height adjustable mobility handle translates along at least a longitudinal portion of the mast between the top end of the mast and the bottom end of the mast, wherein the mobility handle is configured to receive an applied force to stably ambulate the device over a support surface under the applied force. ### Claim 16 (depends on 1) The device of claim 1, further comprising a deployable connection port connected to the first or the second base leg to connect the mobility assistance device to another mobility device. ### Claim 17 (depends on 16) The device of claim 16, wherein the another mobility device is a wheelchair. ### Claim 18 (depends on 1) The device of claim 1, wherein the first and second base legs are rotatably connected to the bottom end of the mast to provide a stored configuration wherein the base legs are substantially parallel to the mast and a deployed configuration wherein the base legs and the mast form the mast angle having the acute angle. ### Claim 19 (depends on 1) The device of claim 1, wherein the outlet strip mount is rotationally and translationally connected to the pole to independently position the outlet strip in any vertical and rotational position with respect to the pole. ### Claim 20 A mobility assistance device comprising: a mast that is a central pole angled with respect to horizontal; a first base leg connected to the mast; a second base leg connected to the mast; wherein the first and second base legs form an open two-sided base footprint having a triangle or truncated triangle footprint; wherein the mast and the base footprint form a mast angle having an acute angle so that the mast extends within a region that vertically extends from the two-sided base footprint; a first wheel connected to the first base leg; a second wheel connected to the second base leg; a third wheel connected to a vertex region, wherein the vertex region is formed by one end of each of the first and second base legs connected to a bottom end of the mast;
