Problems solved by technology

Existing hand-held analyzers have one or another deficiency in the above-mentioned aspects, and cannot meet the requirements of obtaining high-precision reaction color data.
[0004] In addition, the analysis results of the existing handheld bioanalytical detectors only have a qualitative result. For example, the detection of pregnancy can only detect pregnancy or non-pregnancy, and the result of pregnancy weeks cannot be obtained.
In addition, the existing hand-held biological detection equipment is not universal. Each type of detector can only detect one detection item. If you want to detect multiple items, you need different types of detectors to use, which is very inconvenient.

Embodiment 1

[0063] like Figures 1 to 3 As shown, the device for determining the physiological parameters of the human body based on the reaction color of the body fluid test paper in this embodiment includes: a housing 1, the housing 1 is provided with an insertion port for the test paper to be inserted into, and a control circuit board is arranged inside the housing. The control circuit board includes at least a controller and a reaction color acquisition module, the reaction color acquisition module includes a lighting device and a detection data acquisition device for obtaining reaction color parameters on the test paper, wherein the detection data acquisition device is a photoresistor Assemblies or color sensor assemblies, the power supply battery of the control circuit board outputs the power required for the operation of the lighting device and the detection data acquisition device through the voltage stabilizing circuit; the housing is also provided with a test paper or a test pape...

Embodiment 2

[0068] like Figure 4 , 5 As shown, the present embodiment is based on the device for determining the physiological parameters of the human body based on the reaction color of the body fluid test paper. On the basis of Embodiment 1, a collection window 42 is provided in the housing corresponding to the reaction color collection module, and the collection window passes through Surrounded by four interconnected baffles 424, the side wall of the collection window is in a sloped structure 423, and the horizontal window of the collection window is gradually narrowed from the light source of the lighting device to the direction in which the light source extends, in the direction that the test paper is inserted into the housing Vertical is vertical, and vertical vertical is horizontal.

[0069] In this embodiment, the light source emitted by the lighting device is collected through the collection window to prevent the light emitted by the lighting device from spreading out.

Embodiment 3

[0071] This example Figure 6 , 7 As shown, the present embodiment is based on the device for determining the physiological parameters of the human body based on the reaction color of the body fluid test paper. On the basis of Embodiment 3, n-1 partitions 422 are arranged in the collection window, and the partitions divide the collection window into There are n independent small windows 421, and each independent small window corresponds to a group of lighting devices. In this embodiment, the setting of the partition increases the intensity of the LED light, reduces the interference between the LED lights, and avoids the interference between the two lines as much as possible.

[0072] The extended embodiments of the above-mentioned embodiments, on the basis of the above-mentioned embodiments, further include data input and output components connected to the controller, and the input and output components at least include: arranged on the housing for A display screen for displ...

Abstract

The invention relates to an apparatus and system for determining human body physiological parameters based on the reaction color of body fluid test paper. The apparatus and system are designed for obtaining more accurate parameters of test paper color reactions. The apparatus comprises a shell, which is provided with a slot for inserting test paper. A control circuit board is arranged in the shelland at least comprises a controller and a reaction color collection module. The reaction color collection module comprises an illumination device and a detection data acquiring device for obtaining the reaction color parameters of test paper. The battery of the control circuit board supplies sufficient power to the illumination device and the detection data acquiring device through a voltage stabilizing circuit. The shell is also provided with a socket for inserting test paper or a test paper bearing device. The provided apparatus and a test paper bearing device can obtain more accurate reaction color parameters of test paper.

Description

technical field [0001] The invention relates to the technical field of biological monitoring, in particular to a device and a system for determining human physiological parameters based on the reaction color of body fluid test paper. Background technique [0002] Test paper, generally detects the presence of certain substances in liquids or gases through color changes, and semi-quantitatively detects the concentration of the contained substances. At present, most test paper tests can only rely on visual judgment to judge the test results. Since different people have different abilities to distinguish colors, the test results vary from person to person. Especially when the sample concentration reaches the detection limit of the test paper, the color area of ​​the test paper is in a critical state, and factors such as the intensity of external light and people's ability to distinguish colors may make it impossible to determine whether the test result is negative or positive on...
