Abstract: A method and system for guiding use of an inhaler is proposed. The method may include receiving, by a user terminal, from an auxiliary terminal worn on a part of the user's body and interlocking with the user terminal, a detection value obtained by detecting a user's action including at least one of motion or sound in association with the use of the inhaler. The method may also include analyzing the detection value by the user terminal. The method may further include determining, by the user terminal, a completion status of the user's action. The method may further include outputting, by the user terminal, result information regarding a result of the user's performing an action.

Abstract: Disclosed is a chamber for inspecting a liquid substance, the chamber being inserted into a tester for use, and the chamber includes: a chamber sheet comprising a sheet body, an injection groove, and an air outlet formed in a longitudinal direction in the sheet body; and a chamber plate comprising a grip portion and an inserting portion extending in the longitudinal direction from the grip portion. A fastening space to receive and fasten the chamber sheet is formed as a recess in the insertion portion, and wherein where a sample section in which a liquid substance sample is injected and retained is formed in the fastening space.

Abstract: Disclosed is a tester stand including: a body having a predetermined height, and a chamber task area and a device task area each formed in a groove shape engraved in an upper surface of the body; a chamber seating portion formed by protruding from a bottom surface of the chamber task area and in which the chamber is placed; a device seating portion having a device insertion groove formed in a bottom surface of the device task area so that a part of the tester is seated therein, and having a downward fastening insertion groove on the bottom surface of the device insertion groove; and a height adjustment portion fitted into the fastening insertion groove so that a support plate is positioned on the bottom surface of the device insertion groove.

Abstract: Disclosed is a liquid substance inspecting apparatus including: an upper housing; a battery fastened to the upper housing and supplying power; a controller; and a second terminal formed in the upper surface of the controller and coming into contact with the battery when a chamber is inserted; a Printed Circuit Board (PCB) supporter disposed below the controller, and configured to support the controller and move vertically toward the battery upon insertion of the chamber, thereby causing the second terminal to contact the battery; a lower housing formed with an insertion hole into which the chamber is inserted, in which the controller and the PCB supporter are fastened to an internal fastening structure, and which is fastened to the upper housing; and a lens unit installed inside the lower housing to enable a user or a user terminal to check a liquid substance contained in the chamber.
