Abstract

The invention relates to a color collection device for a reagent strip. The device comprises a display device, a contact image sensor, and an objective table support, wherein the display device, the contact image sensor, and the objective table support are installed on a main body. The contact image sensor includes a sensor rack body; a sensor circuit board is arranged on the top of the sensor rack body; a photodiode array is installed below the sensor circuit board; a filter film is arranged below the photodiode array; a linear focusing lens is arranged below the filter film; and a light-emitting diode array is arranged on at least one side surface of the linear focusing lens. A piece of protection glass is installed at the lower surface of the sensor rack body; and a predetermined included angle is formed between the plane where the light-emitting diode array is located and the protection glass plane. The objective table support is arranged under the contact image sensor and is provided with an objective table sliding slot; an objective table guide rail is arranged in the objective table sliding slot; an objective table is installed in the objective table sliding slot in a sliding mode; and an object groove is formed in the objective table. With the color collection device, measurement on a dry-chemical-method reagent strip and a colloidal gold reagent strip can be realized.

Description

technical field [0001] The invention belongs to the color collection technology for reagent strips. In particular, it relates to a color collection device for reagent strips. Background technique [0002] Only by human eyes to identify the color of the reagent strips, the accuracy is not high, and it is often necessary to detect the reagent strips with the help of instruments and equipment. In the prior art, for the detection of dry chemical reagent strips, it is generally irradiated with a point light source, and the color is collected through a photodiode with a color filter. If multiple indicators are detected, a transmission structure is required, which is formed by the movement of the point. Linear scan. [0003] The white light emitted by the point light source is irradiated on the reagent strip through the light hole of the spherical integrator, and the reagent strip reflects the light into the spherical integrator and passes through the color filter to obtain monoc...
