Portable flow meter for low volume applications
First Claim
1. An apparatus, comprising:
- a substrate having a surface and a channel, wherein the channel includes a first end, a second end, and a body with a volume;
a valve coupled to the channel at the first end, wherein the valve is configured to allow a fluid to pass into the channel when the valve is open; and
a continuity detector electrically coupled to the valve and to the channel at the second end, wherein the continuity detector is configured to be activated when the fluid in the channel fills the volume and contacts the continuity detector, and wherein the continuity detector is further configured to transmit a signal to cause the valve to close and to cause the body of the channel to contract and eject the fluid through the second end of the channel.

Abstract
An apparatus is disclosed that may include a substrate that may have a surface, a channel of a volume that may be defined, at least in part, by the substrate, wherein the channel may have a first end and a second end, a valve may be coupled to the channel at the first end, wherein the valve may be configured to allow a fluid to pass into the channel when the valve is open, and a continuity detector, which may be coupled to the channel at the second end, wherein the continuity detector may be activated when the fluid contacts the continuity detector, wherein the continuity detector may further be configured to provide a signal to close the valve and remove the fluid from the channel. A method for calculating a rate of flow of a fluid collected from a bodily surface into a body-worn device is disclosed.

15. An apparatus, comprising:
-
a substrate having a surface and a channel, wherein the channel includes a first end, a second end, and a body with a volume, and wherein the first end of the channel is configured to allow a fluid to pass into the channel; a valve coupled to the channel at the second end, wherein the valve is configured to control passage of the fluid through the channel; and a continuity detector electrically coupled to the valve and to the channel at the second end, wherein the continuity detector is configured to be activated when the fluid in the channel fills the volume and contacts the continuity detector, and wherein the continuity detector is further configured to cause the body of the channel to contract and eject the fluid through the valve of the channel.
