Description

[0001] The present invention relates to an apparatus for measuring biometric information using an ejecting button,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a biometric information measuring apparatus using a biosensor, and more particularly, to a technique for measuring and discharging a biosensor used for measurement.

After removing the biosensor used for measurement in the measuring device after measuring the biomass by the biological sample such as blood, patients are reluctant to put the biosensor in the hand when the biosensor is removed from the measuring device. In particular, doctors and nurses in hospitals are reluctant to handle biosensors on patients' blood after measuring their body fluids.

Korean Patent No. 118,273, filed Apr. 13, 2011, and registered on September 9, 2012, discloses a strip analyzer that rubs the upper surface of a strip inserted with a rotating wheel and discharges it manually. However, at the entrance where the biosensor is inserted, there is disposed a sensor for reading biosignals, a read sensor for reading the identification information displayed on the surface of the biosensor, and a guide structure for aligning the biosensor with the sensor , It is very difficult to secure a space for placing a large cylindrical wheel in contact with the upper surface of the strip.

The ejector of the bio-information measuring device can be inserted to remove the disposable biosensor already used safely and conveniently, and the bio-sensor with the bio-sample can be minimized by the user to avoid the infection.

Furthermore, a discharge structure of a strip capable of achieving stable discharge of a strip in a mechanical structure into which a biosensor is inserted is proposed.

A biometric information measuring apparatus includes a cover, a housing coupled to the cover, a circuit board accommodated in the housing and having a receiving groove on one side thereof, an optical sensor arranged on one side of the substrate and aligned with the receiving groove of the circuit board, A strip connector mounted on the other surface of the substrate aligned with the receiving groove and having a strip insertion hole for guiding the insertion of the strip therein and at least one guide slot formed on the upper surface along the strip insertion hole, At least one ejector hook protruding into the guide slot and guided along the guide slot and pushing and ejecting the inserted strip is formed on the inner side and has a shape enclosing a part of the periphery of the strip connector and is fastened to the strip connector slidably, And a fixing hook which is elastically deformed downward in the ejector, an ejector having one end fixed to the ejector, And an ejector fixing portion formed on an upper portion of the ejector and provided with a catching jaw which is engaged when the fixing hook is not deformed.

The cover further includes an eject button on the upper part of the cover, when aligned with the fixing hook, for ejecting the strip by moving the ejector when pressed.

The ejector ejects the strip by pushing the stepped portion formed due to the difference in length between the ends of the inserted strip, or between the layers of the strip.

The ejector fixing portion further includes a pair of ejector guide grooves pierced so as to be slidable in forward and backward directions while restricting the upward and downward movement of the ejector. The ejector includes a pair of ejector guide projections slidably engaged with the ejector guide groove .

The ejector fixing portion is fixed to the circuit board in the form of wrapping a strip connector and a part of the ejector.

The strip connector further includes a sensing hole formed at a position corresponding to the receiving groove of the circuit board.

The strip connector further includes a plurality of connector terminals having a shape protruding inwardly to be electrically connected to the terminals of the surface of the biosensor strip when the biosensor strip is inserted, and protruding portions formed on the protrusions.

The strip insertion hole of the strip connector has a guide groove for guiding the insertion of the strip formed at the entrance thereof, an insertion guide hole formed continuously to the guide groove and having a first width larger than the thickness of the strip, And a connection guide hole projecting inwardly from the connector terminal and having a second width corresponding to the thickness of the strip and narrower than the first width.

After the biometric information measurement, the biosensor with the blood of the other person, which may have a dangerous pathogen, can be easily and safely removed from the measuring device, thereby reducing the possibility of pathogen transmission.

Structurally, the strip can be stably ejected without detracting from the design of the mechanical structure into which the strip is stably read.

A color tag that records identification information of the biosensor is attached to the strip and the identification information of the biosensor is optically read from the color tag through the optical sensor, Various kinds of identification information such as a correction code for correction and a unique number can be read. As a result, the measurement value can be obtained conveniently and accurately.

In addition, since the connection terminals of the strip are very sensitive to transmission, hygiene of the terminal portion is important in order to reduce the risk of infection through the blood. Since the strip connector and the circuit board include the foreign material discharge hole, It is hygienic because it can be discharged.

Since the biometric information measuring device can be used semi-permanently, it is possible to protect the environment and to conserve materials by using a disposable strip biosensor having a low unit price when measuring biometric information.

The color tag indicated with the identification information is attached to the back surface of the strip, and various kinds of identification information such as the type, the manufacturer, and the unique number of the mounted biosensor can be read by the optical sensor mounted on the strip connector 90. The strip 60 may be composed of a plurality of layers. At least two electrodes are located on the substrate layer and a portion of the electrodes may be associated with an enzyme that causes a current proportional to the amount of blood glucose to flow between the electrodes when the biological sample is introduced.

When the sample is injected and the enzyme dissolved, the analyte contained in the sample reacts with the enzyme to oxidize the analyte, thereby reducing the electron acceptor. After the completion of the enzyme reaction, the concentration of the analyte contained in the sample can be calculated by measuring the oxidized current value obtained by electrochemically oxidizing the reduced electron acceptor.

The biosensor can form an electrode system including a plurality of electrodes on an insulating substrate by a method such as screen printing. According to one embodiment, an insulating film may be formed on the electrode. Above it, a spacer, which is shorter than the substrate layer, is squeezed on which a flow of air can flow so that the blood can flow well, on which a cover layer shorter than the substrate layer can also be squeezed. For this reason, the strip may include a step. The reason why the spacer and the cover are shorter than the substrate layer is that the electrode is led out to one end and contacts the electrode inside the bioinformation measuring apparatus when the strip is inserted. According to one embodiment, the strip may include an insertion sensing electrode for sensing insertion and a measurement electrode for inspecting the blood glucose level. There may also be a hole at the top of the cover layer so that blood flows into the inside of the strip at one end of the strip. Accordingly, when blood flows in from one end of the strip, the blood flows into the electrode at the other end of the strip along the space of the spacer, and the blood glucose and the enzyme react with each other, The amount of blood sugar can be confirmed.
