- the second layer L2 is attached on the first layer L1 to induce an electrochemical reaction of disease agent in saliva. That is, as shown in (d) of FIG. 8, when the disease agent is glucose, the second layer L2 reduces hydrogen peroxide generated during the glucose decomposition process of the third layer L3 and oxidizes itself. Current is generated in the process of sending and receiving electrons.
- the second layer (L2) may be composed of a nanostructure made of a porous metal-organic solid structure. Nanostructures are non-toxic catalysts with no biohazards, which reduce the output of glucose metabolism by electrochemical methods and oxidize themselves at the electrodes to generate current signals.
- the nanostructure has a chemical composition of M a (II) M ′ b (III) (CN) 6 , and M and M ′ may be metal elements.
- M 2+ and M '3 + a metal cation and CN - to promote rapid reduction of the solids is water structure consisting of cyanide anion coordinated water metabolism of the enzyme by the electrochemical catalytic properties of the central metal cation of hydrogen peroxide .
- M and M ' is a metal element Fe, Zn, K, Mg, Al, Cu, Co, Ni, Cr, and the like can be Mn, Rb, as an example nanostructure is based on Fe 2 + and Fe 3 + It may be a Prussian blue structure, Fe 4 III [Fe II (CN) 6 ] 3 .
- the saliva detection unit 163 having a high sensitivity may be configured through the nanostructure.
- the first layer L1 is formed of an electrode connected to the device connection part 161. That is, the first layer L1 provides the device connection unit 161 with the current generated in the second layer L2.
- the first layer (L1) is shown in the drawing as a three-electrode (three-electrodes) consisting of the reference electrode (EN1), the working electrode (EN2) and the auxiliary electrode (EN3), but is not limited to this embodiment Accordingly, the first layer L1 may be configured in the form of two-electrodes.
- the saliva detection unit 163 may further include a filtration membrane or a thin membrane. can do.
- the saliva detection unit 163 may further include a filtration membrane capable of sensing only a specific disease agent from various interference substances in the saliva.
- the saliva detection unit 163 may further include a thin film for the role of an electrolyte and a protein or DNA material that exhibits selective electrochemical signal response to disease factors only.
- FIG. 11 is a flowchart illustrating a diagnostic method using a diagnostic device using saliva according to a preferred embodiment of the present invention.
- the diagnostic device 100 applies a constant voltage to the detector 160 coupled to the diagnostic device 100 (S110).
- the diagnosis device 100 diagnoses a disease using saliva (S130). That is, the detection unit 160 induces an electrochemical reaction of the disease agent in the saliva sampled through the applied voltage. In addition, the detection unit 160 provides the current generated by the electrochemical reaction of the disease agent to the diagnostic device 100.
- the diagnostic device 100 converts the diagnostic data (that is, the result of measuring the current generated by the detection unit 160) into a digital signal (S150).
- the diagnostic device 100 provides a digital signal to the user terminal 200 through the communication network 300 (S170). Then, the user terminal 200 converts the digital signal provided from the diagnostic device 100 to the concentration of disease agent based on a preset calibration curve.
- the invention can also be embodied as computer readable code on a computer readable recording medium.
- the computer-readable recording medium includes all kinds of recording devices in which data that can be read by a computer is stored. Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and also carrier wave (over the Internet). Transmission).
- the computer-readable recording medium can also be distributed over computer devices connected over a wired or wireless communication network so that the computer-readable code is stored and executed in a distributed fashion.
Abstract
L'invention concerne un dispositif de diagnostic utilisant la salive et un procédé de diagnostic correspondant. La présente invention permet de diagnostiquer des maladies en utilisant la salive et non le sang ; permet une utilisation en fonction d'une utilisation spécifique (ou permet la mesure d'une maladie spécifique) par la réaction d'une partie détection correspondant à l'utilisation (ou maladie) spécifique avec la salive ; permet de diagnostiquer une maladie plusieurs fois par jour sans aucune douleur en utilisant la salive ; présente un avantage économique par la sélection d'une partie détection en fonction d'une utilisation (ou maladie) spécifique afin de détecter la maladie spécifique ; et permet de fournir un résultat de mesure à un terminal utilisateur de telle sorte qu'un utilisateur puisse gérer sa santé en fonction du résultat de mesure, ce qui permet un soin de santé personnalisé autonome.
