- a chronic disease such as diabetes requires continuous management
- a body attachment unit for measuring biometric information attached to the body may be used to manage blood sugar of a diabetic patient.
- Diabetes is characterized by almost no subjective symptoms in the early stages, but as the disease progresses, the symptoms characteristic of diabetes such as next, large meals, polyuria, weight loss, general malaise, itching of the skin, and prolonged wounds on the hands and feet do not heal. appears. As diabetes progresses further, complications such as vision impairment, high blood pressure, kidney disease, stroke, periodontal disease, muscle spasms and neuralgia, and gangrene appear.
- a blood glucose meter is divided into a method in which a blood glucose meter is collected from a user's fingertip and blood glucose measurement is performed once, and a method in which a blood glucose meter is attached to a user's stomach or arm and continuously measures blood glucose.
- hypoglycemia In the case of diabetic patients, they usually go back and forth between hyperglycemia and hypoglycemia, and emergency situations come from hypoglycemia, and if the hypoglycemia lasts for a long time without a supply of sugar or loss of consciousness, life may be lost. Therefore, immediate detection of a hypoglycemic state is very important for diabetic patients, but there is a limit to accurately detecting it with a blood glucose meter that measures blood sugar intermittently.
- CGMS continuous glucose monitoring system
- a continuous blood glucose measurement system includes a body-attached unit including a transcutaneous sensor inserted into the user's skin to measure blood glucose in the body, and a terminal that receives and outputs biometric information transmitted from the body-attached unit.
- the body attachable unit is composed of a sensor unit including a transcutaneous sensor and a base unit electrically connected to the sensor unit to generate a measurement signal from measurement information of the sensor unit and transmit the measurement signal to a terminal or the like.
- a body-attached unit of a continuous blood glucose measurement system is attached to a user's skin for several days to several tens of days to measure blood sugar. Therefore, in order for the body attachment unit to be attached to the user's skin and operate smoothly, it is necessary to prevent foreign substances such as moisture from penetrating into the internal electronic components of the body attachment unit.
- the present invention has been devised in consideration of the above points, and an electrical connection between a sensor unit including a sensor inserted into the user's skin to measure biometric information and a base unit attached to the user's skin is It is an object of the present invention to provide a body attachment unit for measuring biometric information that can prevent contamination with foreign substances and increase its useful life.

- the mounting portion includes a base unit recess and a contact surface provided inside the base unit recess to attach the adhesive layer, and an insertion hole through which the sensor can pass is formed inside the base unit recess.
- the sensor unit housing is disposed to pass through the base unit housing, and the sensor unit housing protrudes from the housing body and is inserted into the insertion hole so that a housing body fitted into the base unit recess and a portion of the sensor pass therethrough.
- a boss may be included, and the adhesive layer and the sensor unit electrical contact may be provided on the housing body.
- the base unit recess includes a first recess connected to the insertion hole, and a second recess positioned farther from the insertion hole than the first recess and connected to the first recess;
- the set may be wider than the first recess, and the housing body may include a body portion fitted to the first recess and a cover portion wider than the body portion to be fitted to the second recess.
- the sensor includes a sensor body disposed inside the sensor unit housing and an insertion part protruding from the sensor unit housing and connected to the sensor body so as to be inserted into a user's skin, and the base unit electrical contact part includes the sensor body.
- the sensor body may be contacted through an adhesive layer hole and a through hole provided in the sensor unit housing.
- an electrical connection between a sensor unit including a sensor inserted into the user's skin to measure biometric information and a base unit including an electronic component and electrically connected to the sensor unit connects the sensor unit and the base unit to each other. It can be stably sealed by the bonding adhesive layer. Therefore, there is no problem of moisture, foreign substances, or bodily fluids flowing into the electrical connection between the sensor unit and the base unit, and the biometric information can be stably measured by being attached to the user's skin for a long time.
- the sensor unit and the base unit can be firmly coupled by simply bonding the sensor unit and the base unit using a simple adhesive layer.
