Description

Continuous Anaylyte Measurement Device With Sensor Guide}

The present invention relates to a continuous analyte meter having a protruding guide.

When using the inserter as a reference position, one end 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. It can be called distal.

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 portion and the distal portion 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 the electrical circuitry necessary for measuring analytes, including glucose.

The transmitter can be placed inside the insert along with an electrochemical sensor before being attached to the skin. A type in which a transmitter and an electrochemical sensor are pre-combined can be called an all-in-one type transmitter.

The transmitter is in signal communication with the sensor, wherein the sensor is configured to detect and measure the patient's glucose level for a predetermined period of time and to transmit data corresponding to or related to the measured glucose level for a predetermined period of time for further analysis. .

The proximal portion of the electrochemical sensor may be located at an opposite end to the distal portion of the electrochemical sensor, at least a portion of which is inserted into the body. The proximal portion of the electrochemical sensor may be electrically connected to the main board of the transmitter containing the electrical circuitry necessary for glucose measurement.

The transmitter may be provided with a needle for penetrating the electrochemical sensor into the skin of the body, and the needle passed into the skin can be separated from the skin while maintaining only the electrochemical sensor penetrated into the skin.

In order to attach the transmitter to the body's skin, it needs to be moved securely within the inserter.

Additionally, the needle must prevent the distal part of the electrochemical sensor from being separated from the needle when guiding the distal part of the electrochemical sensor to invade into the skin.

Moreover, when the needle is inserted into the skin and then removed to the outside, the electrochemical sensor must reliably maintain the invasive state in the skin.

The present invention provides a continuous analyte measuring device equipped with a transmitter having a protruding guide to ensure that the electrochemical sensor remains invasive within the skin when the needle penetrated into the skin is separated from the skin.

The present invention provides an electrochemical sensor that invades into the skin; It includes a main board to which the electrochemical sensor is connected and a housing in which the main board is stored, the housing is attached to the skin, and the main board is a transmitter that inputs and outputs signals of the electrochemical sensor; a needle that penetrates the electrochemical sensor into the skin; an inserter that moves the transmitter or needle from a first position to a second position so that the needle penetrates the skin; Including,

A part of the electrochemical sensor is inserted into the needle, and a penetration space through which the needle penetrates and a part of the electrochemical sensor passes is formed in the transmitter, and a protrusion supporting a part of the electrochemical sensor is formed in the penetration space. A continuous analyte meter provided with a guide may be provided.

As such, the present invention is a structure in which an upper penetration space and a lower penetration space are formed in the upper lid and the lower lid forming the transmitter, and an upper protrusion guide and a lower protrusion guide are provided on the inner surfaces of the upper penetration space and the lower penetration space, respectively. , the distal part of the electrochemical sensor guided by the needle penetrates into the skin together with the needle, and then when the needle is separated, the distal part of the electrochemical sensor can remain inserted without being separated out of the skin.

Electrochemical sensors are thin and flexible to reduce foreign body sensation. When inserting a needle and sensor, the needle makes a hole in the skin and a thin electrochemical sensor is inserted through the hole. At this time, a problem may occur in which the electrochemical sensor is not inserted into the skin due to the resistance of the skin, or only the needle is inserted into the skin and the electrochemical sensor is pushed out of the skin.

In order to improve this, the protrusion guide of the present invention positions the folded part of the sensor inside the needle and supports the folded part closely below and above the folded part, thereby preventing the sensor from being pushed down or up based on the folded part.

Figure 16(a) is a comparative example without a protruding guide, and there is a risk that the proximal portion may be pushed to the upper side of the folded portion due to the folded portion being pushed against the skin.

Figure 16 (b) clearly explains the anti-slip function of the protruding guide of the present invention located in the needle. Since the protruding guide supports the sensor adjacent to the folded part, the phenomenon of the proximal part being pushed upward due to the resistance of the skin can be minimized.

This may be almost the only solution to prevent sensor insertion failure.

The protruding guide may be adjacent to the fold of the electrochemical sensor. When inserting the needle, the protruding guide can prevent the proximal portion of the electrochemical sensor from being pushed toward the upper side of the folded portion.

In addition, the protruding guide can guide the folded portion to remain inside the needle even if the electrochemical sensor is pushed out by the resistance of the skin, thereby suppressing sensor insertion failure as much as possible.

Meanwhile, in order to prevent the phenomenon where only the needle is inserted and the sensor bounces off the skin, the needle holder and protrusion guide combine to make the space as narrow as possible to prevent the sensor from falling out. In other words, the sensor can be inserted reliably by eliminating any empty space where the sensor can be pushed.

Referring to Figure 5, the needle is provided with a needle holder inserted into the penetration space, and an incision may be formed in the needle holder. A portion of the electrochemical sensor may be in close contact with the gap formed by the incision and the protruding guide.

The upper side of the needle holder contacts the upper part of the transmitter or the transmitter holder supporting the transmitter and can regulate the lowering position of the needle. The upper side of the needle holder may be thicker than the penetration space for this purpose. On the other hand, the lower side of the needle holder is inserted into the penetration space to prevent the needle from shaking and is fitted into the penetration space to prevent lateral flow. The cut portion corresponding to the lower side of the needle holder has a smaller thickness than the upper side of the needle holder and can be inserted into the through hole. If the folded part of the electrochemical sensor is inserted between the narrow gap between the incision and the protruding guide, the space for the sensor to roll up can be completely eliminated.

The protruding guide is larger than the needle so that it can be inside the needle. Because it is thick, there is a risk of it breaking. To prevent this, the protruding guide may have a form in which a portion of the support wall of the through space is exposed in the direction of the through space. When the protruding guide is a part of the support wall forming the penetrating space, the protruding guide is integrated with the upper lid or lower lid, so the rigidity is improved and the guide is resistant to breakage.

The penetrating space is, as shown, a closed hollow or long hole, but is not limited thereto. The penetration space may be in the form of a long depression in a portion of the side of the transmitter. The opening, which is an open portion of the depression, corresponds to the side of the transmitter, and a protruding guide may protrude toward the opening on the inner side wall of the depression.

When the electrochemical sensor is provided in the transmitter, the lower support wall of the lower penetration space is coupled to the upper penetration space and is disposed by passing from the distal part of the electrochemical sensor to the connection through the cut groove of the lower support wall, where the connection is Since it is provided between the upper protruding guide and the lower protruding guide and is in close contact, there is no shaking, and the arrangement relationship with the needle can be aligned. Therefore, separation of the electrochemical sensor can be reliably prevented when the needle is separated from the inside of the skin.
