Device for fluid treatment of the skin

A skin-treatment system comprising:

• a plurality of fluid reservoirs;
• a selection valve operatively connected to each of the plurality of fluid reservoirs, the selection valve having:
• a first setting that allows treatment fluid to flow from a first fluid reservoir of the plurality of fluid reservoirs, and
• a second setting that allows treatment fluid to flow from a second fluid reservoir of the plurality of fluid reservoirs;
• a first pump operatively connected to the selection valve;
• a pinch valve operatively connected to the first pump and configured to inhibit treatment fluid from flowing through the first pump when the first pump is turned off;
• a handpiece comprising
• a treatment tip configured to apply treatment fluid from one or more of the plurality of fluid reservoirs via the selection valve and the first pump to a skin surface, the treatment tip comprising a vacuum inlet configured to aspirate waste fluid away from the skin surface, and
• a fluid control valve configured to control fluid flow to the treatment tip within a range of fluid flow rates;
• a second pump operatively connected to the vacuum inlet of the treatment tip;
• a vacuum control valve operatively connected to the second pump and configured to control an amount of vacuum applied at the vacuum inlet of the treatment tip;
• a waste chamber operatively connected to the second pump and configured to receive the waste fluid;
• a main power switch having
• an “on” setting under which electrical current is allowed to flow to both the first pump and the second pump, and
• an “off” setting under which electrical current is prevented from flowing to both the first pump and the second pump;
• and
• a momentary switch located on the handpiece, the momentary switch having
• an “on” setting under which electrical current is allowed to flow to the first pump, and
• an “off” setting under which electrical current is prevented from flowing to the first pump;
• wherein the first pump is activated only when both the main power switch and the momentary switch are in their respective “on” settings;
• wherein the momentary switch is in its “on” setting only when the momentary switch is being pressed;
• wherein treatment fluid is pumped from one or more of the plurality of fluid reservoirs via the selection valve and the first pump to the skin surface only when the momentary switch is being pressed;
• and
• wherein treatment fluid is prevented from flowing from the plurality of fluid reservoirs via the selection valve and the first pump to the skin surface when the momentary switch is not being pressed.
