Abstract
Multistage vaporizers, such as for use in medical treatment systems, as well as related methods are described. In one example, a multistage vaporizer includes a first reservoir configured to hold a liquid and one or more pumping transducers positioned in the first reservoir. The multistage vaporizer also includes a second reservoir and one or more vaporizing transducers positioned in the second reservoir. The one or more pumping transducers positioned in the first reservoir are configured to generate and move droplets of a liquid in the first reservoir to the second reservoir, and the one or more vaporizing transducers positioned in the second reservoir are configured to create a vapor of the liquid in the second reservoir.
Claims17
A multistage vaporizer comprising:
- a first reservoir configured to hold a liquid;
- one or more pumping transducers positioned in the first reservoir;
- a second reservoir positioned at least partially above the first reservoir, the second reservoir comprising a wall configured to hold the liquid, wherein the wall includes one or more clefts configured to allow the liquid to drain therethrough to maintain a constant depth of the liquid within the second reservoir, wherein the liquid that drains through the one or more clefts drains to the first reservoir;
- one or more vaporizing transducers positioned in the second reservoir, wherein:
- the one or more pumping transducers positioned in the first reservoir are configured to generate and move droplets of the liquid in the first reservoir to the second reservoir, and
- the one or more vaporizing transducers positioned in the second reservoir are configured to create a vapor of the liquid in the second reservoir.
A method comprising:
- generating and moving droplets of a liquid from a first reservoir to a second reservoir using one or more pumping transducers positioned in the first reservoir, the one or more pumping transducers vibrating at a first frequency,
- generating a vapor of the liquid in the second reservoir using one or more vaporizing transducers positioned in the second reservoir, the one or more vaporizing transducers vibrating at a second frequency, wherein the second frequency is different than the first frequency, wherein the second reservoir is positioned at least partially above the first reservoir and comprises a wall configured to hold the liquid, wherein the wall includes one or more clefts configured to allow the liquid to drain therethrough to maintain a constant depth of the liquid within the second reservoir, wherein the liquid that drains through the one or more clefts drains to the first reservoir.
