Hemoglobin detecting device

A hemoglobin detecting device, comprising:

• a shell component;
• a fixing part, connected with the shell component, wherein the fixing part enables the shell component to be engaged with a smart device;
• a processor unit, mounted inside the shell component;
• a transmission unit, mounted inside the shell component and electrically connected to the processor unit;
• a light source, mounted inside the shell component and electrically connected to the processor unit, wherein the light source generates a first light beam;
• a light detection module, mounted inside the shell component and electrically connected to the processor unit;
• wherein
• the light detection module receives a second light beam and generates a light intensity information according to the second light beam, wherein the first light beam passes through an analyte solution and is reflected to form the second light beam;
• the second light beam includes a first wavelength light, a second wavelength light, a third wavelength light, and a fourth wavelength light, wherein a wavelength of the first wavelength light is smaller than a wavelength of the second wavelength light, the wavelength of the second wavelength light is smaller than a wavelength of the third wavelength light, and the wavelength of the third wavelength light is smaller than a wavelength of the fourth wavelength light;
• the light intensity information includes a first intensity signal relating to the first wavelength light, a second intensity signal relating to the second wavelength light, a third intensity signal relating to the third wavelength light, and a fourth intensity signal relating to the fourth wavelength light;
• the processor unit receives the light intensity information from the light detection module, and determines whether an absorption spectrum of the analyte solution matches a target spectrum;
• the absorption spectrum of the analyte solution matches the target spectrum if:
• the second intensity signal, the third intensity signal and the fourth intensity signal are larger than the first intensity signal;
• and
• the second intensity signal and the fourth intensity signal are larger than the third intensity signal;
• when the absorption spectrum of the analyte solution matches the target spectrum, the processor unit generates a positive result information;
• when the absorption spectrum of the analyte solution does not match the target spectrum, the processor unit generates a negative result information;
• wherein
• the transmission unit receives the positive result information or the negative result information from the processor unit, and transmits the positive result information or the negative result information to the smart device.
