Title Skin permeable gas collector and skin permeable gas measuring apparatus achieved
Abstract (US7261692)
An apparatus for measuring skin permeable gas, which can be used to obtain clinical information by noninvasive and bloodless operations and is useful for in-home medical care and health management.
The apparatus includes a device for collecting skin permeable gas including a container for storing skin permeable gas; a partition, disposed at a lower section inside the container, having an opening at the center thereof; and an operating member for opening and closing the opening of the partition.
Scope of claims [claim1]
1. A device for collecting skin permeable gas, comprising: a container having an opening section, the opening section configured to be brought into intimate contact with skin to collect emitted skin permeable gas, the collected skin permeable gas being delivered and then measured,wherein the container includes: an upper chamber, for storing skin permeable gas and including a ventilation port and delivery port for removing the stored skin permeable gas;
a lower chamber configured to be brought into intimate contact with the skin;a partition, having an opening at the center thereof, for separating the upper chamber from the lower chamber;
and
a push-pull operating member for controlling the flow of the skin permeable gas flowing between the lower chamber and the upper chamber,wherein the lower chamber is configured to be pressed against the skin and then fixed thereto in such a state that the operating member is pressed down to close the opening of the partition using a valve member disposed at the lower end of the operating member, the skin permeable gas emanating from the skin is collected in the lower chamber, the valve member of the operating member is drawn up after the collection to open the opening of the partition to allow the skin permeable gas collected in the lower chamber to flow into the upper chamber, and the valve member of the operating member is then pressed down after a predetermined time to close the opening of the partition to store the skin permeable gas.
