Electronic medication chronolog device

摘要

An electronic medication chronolog device adapted for attachment to various shapes and sizes of conventional pressurized inhalant packages. The packages include in common an actuator housing with one end having a mouthpiece and an opposite end having an opening for receiving a vial/canister therein. The vial/canister having a valve stem used for dispensing a prescribed dosage of medication inhalant in an aerosol chamber inside the actuator housing. The aerosol chamber is disposed next to an outlet of the mouthpiece for dispensing the medication therethrough. The chronolog device includes computing and recording equipment with audio and visual display mounted in a chronolog housing. The chronolog housing is adapted for attachment to the actuator housing. A strain gauge sensing arm is attached to the computing equipment and extends through a hole in a side of the actuator housing for engaging a portion of the vial/canister next to the valve stem. The sensing arm senses and signals the computing equipment when the valve stem of the vial/canister is properly compressed for release of medication. Also, the sensing arm senses and signals the computing equipment when the vial/canister is engaged and disengaged inside the actuator housing Further, a fast response thermistor is connected to the computing equipment and disposed between the hole in the side of the actuator housing and an opening in the chronolog housing. The thermistor senses and signals each occurrence and amount of inhale air flow and exhale air flow in the actuator housing.
