Description

Applicator for Biometric Information Acquisition The present disclosure relates to an applicator for acquiring biometric information. Various diseases occur in modern humans, and in order to properly treat or manage them, a means to acquire human biological information is necessary. Diabetes can be cited as a prime example. To properly manage diabetes, a means to acquire blood glucose information, which is the patient's biological data, is necessary. Recently, continuous glucose monitoring (CGM) devices, which are inserted into the human body to measure blood glucose levels at intervals of minutes, are being developed. To minimize the user's pain and aversion associated with blood sampling, CGM devices can continuously measure blood glucose levels by inserting a needle-shaped sensor into areas such as the abdomen and arms, where pain is relatively less intense. A continuous glucose monitoring device comprises a sensor unit attached to a user's body to measure the user's blood glucose information and transmit the measured blood glucose information, and a terminal that provides the blood glucose information received from the sensor unit to the user, thereby enabling the user to monitor or manage the user's blood glucose information. Here, the sensor unit consists of a sensor module that is inserted and attached to the skin of the user's body to measure blood glucose from the user's body fluids, and a transmitter that transmits the blood glucose level measured by the sensor module to a terminal. The sensor module is equipped with a needle-shaped probe, etc., that is inserted into subcutaneous fat to extract interstitial fluid. An applicator is used to insert and attach the sensor unit to the body. The applicator is configured to insert and attach a sensor unit to the body, and the sensor unit is inserted and attached to the body by user operation; when the applicator is detached and removed from the body while the sensor unit is inserted and attached, only the sensor unit remains attached to the body. Since the sensor unit is inserted into a part of the human body, the sensor unit installed inside the applicator and the internal space of the applicator must be maintained in a sterile state from the manufacturing stage until the consumer uses it, and a dehumidified state must be maintained to preserve electronic components. At the same time, the internal space of the applicator must be sealed from the outside to maintain sterility and dehumidification. Various packaging technologies are being applied to applicators to maintain sterilization, dehumidification, and airtightness, and simplifying packaging and reducing size has become one of the goals of applicator manufacturers. In addition, to insert and attach the sensor unit to the body, the applicator fires the sensor unit in a direction toward the user's body. During this process, a certain amount of air resistance is generated, which may hinder the stable attachment and insertion of the sensor unit.
