Abstract

The present invention may provide a continuous analyzer comprising: an electrochemical sensor that penetrates into the skin; a main substrate to which the electrochemical sensor is connected and a housing in which the main substrate is housed, wherein the housing is attached to the skin and the main substrate is a transmitter that inputs and outputs a signal of the electrochemical sensor; a needle that penetrates the electrochemical sensor into the skin; and an inserter that moves the transmitter or the needle from a first position to a second position so that the needle penetrates the skin. A portion of the electrochemical sensor is inserted into the needle, and a through hole is formed in the transmitter through which the needle penetrates and a portion of the electrochemical sensor passes. The electrochemical sensor includes a proximal portion, a connecting portion formed extending from the proximal portion, and a distal portion that extends from the connecting portion, bends to pass through the through hole, and protrudes to the outside of the transmitter. An inclined groove is formed on one side of the through hole into which the connecting portion is inserted and automatically aligned.

Description

Continuous Anaylyte Measurement Device With A Transmitter That Facilitates Sensor Alignment The present invention relates to a continuous analyte measuring device equipped with a transmitter that facilitates easy alignment of the sensor. When the inserter is used as the reference position, the end portion of the electrochemical sensor connected to the main board is located close to the inserter and can be called the proximal portion, and the other end of the electrochemical sensor inserted into the body is located far from the inserter and can be called the distal portion. The proximal portion of the electrochemical sensor may be electrically connected to the main board of the transmitter, and at least a portion of the distal portion of the electrochemical sensor may be inserted into the body. The proximal and distal portions may be located at opposite ends. The proximal portion of the electrochemical sensor may be electrically connected to the main board of the transmitter, which includes an electrical circuit necessary for measuring analytes including glucose. The transmitter can be located inside the inserter along with the electrochemical sensor before being attached to the skin. A type in which the transmitter and the electrochemical sensor are pre-combined can be called an all-in-one type transmitter. The transmitter communicates with the sensor via signal, and the sensor is configured to detect and measure the patient's glucose level over a predetermined time period, and is configured to transmit data corresponding to or related to the glucose level measured over the predetermined period for further analysis. The proximal end of the electrochemical sensor may be located at the opposite end of the distal end of the electrochemical sensor, where at least a portion is inserted into the body. The proximal end of the electrochemical sensor may be electrically connected to the main board of a transmitter containing an electrical circuit necessary for glucose measurement. The transmitter may be provided with a needle for penetrating an electrochemical sensor into the skin of the body, and the needle, once passed into the skin, may be separated from the skin while maintaining only the electrochemical sensor penetrating the skin. To attach the transmitter to the skin of the body, it needs to be moved securely inside the inserter. In addition, when the needle is guided to penetrate the distal end of the electrochemical sensor into the skin, care must be taken to ensure that the distal end of the electrochemical sensor does not detach from the needle. Furthermore, when the needle is inserted into the skin and then withdrawn, the electrochemical sensor must reliably maintain its position within the skin. In addition, when assembling the electrochemical sensor inside the housing during the manufacturing process of the transmitter, it is necessary to maintain the assembled state of the sensor in an accurate position without shaking. If the electrochemical sensor is not accurately aligned inside the transmitter, the misalignment between the distal end of the electrochemical sensor and the needle may result in a defect where the needle is not accurately inserted into the user's skin or causes pain during the invasive action of the inserter. delete delete FIG. 1 is a schematic diagram showing the structure of an inserter forming an analyte measuring device according to the present invention.
