Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a handheld hemoglobin detector. Background Art

[0002] In the field of medical health, hemoglobin, as a crucial component of human blood, plays an irreplaceable role in maintaining the normal physiological functions of the body. Hemoglobin is mainly responsible for binding with oxygen in the lungs and transporting it to various tissues and organs throughout the body. At the same time, it can bring back the carbon dioxide produced by the tissues and organs to the lungs for excretion. This process ensures the normal aerobic respiration of cells and the normal progress of metabolism. Therefore, hemoglobin detection is of great significance for comprehensively evaluating the human health status. It is a core indicator for diagnosing blood diseases such as anemia. By measuring the content of hemoglobin, doctors can accurately judge whether the patient has anemia symptoms and the severity of anemia, and then formulate targeted treatment plans. Therefore, a handheld hemoglobin detector is designed.

[0003] Existing handheld hemoglobin detectors lack a suitable detection sample placement structure, or the placement structure is not conducive to the penetration of detection light, affecting the detection accuracy. At the same time, they lack effective dust-proof measures, and dust and impurities are likely to enter the device, interfering with the detection results. In addition, they lack a convenient fixing structure and are difficult to be stably fixed on the arm or other parts in specific scenarios (such as when the patient is moving or inconvenient to hold), which brings inconvenience to users.

At the rear end of the bottom shell 1, a charging port 11 is provided. The charging port 11 is electrically connected to the battery 12. The charging port 11 is a common Type-C interface and is electrically connected to the battery 12. The battery 12 is electrically connected to the circuit board 13. A processor 131 is soldered onto the circuit board 13. The photodetector 14 is electrically connected to the processor 131. Both the top shell 2 and the bottom shell 1 are made of a polycarbonate and acrylonitrile-butadiene-styrene copolymer alloy material. A control panel 21 is fixed on the top shell 2. The control panel 21 is adhesively fixed to the top shell 2 with fixing glue. The processor 131 is of the STM32F103 type, and the photodetector 14 is of the Hamamatsu S1336 type. The control panel 21 is electrically connected to the processor 131 through a cable with a length of 5 cm. And a display screen 22 is fixed on the top shell 2. The display screen 22 is a liquid crystal display (LCD) with a size of 2 inches. The display screen 22 is connected to the processor 131 through a flexible printed circuit (FPC) with a length of 4 cm. Its function is: The user issues instructions such as starting detection and selecting functions by operating the buttons or the touch panel. After the processor 131 receives and processes them, the results are fed back to the display screen 22 for display, facilitating the user to directly obtain the detection data. The charging port 11 provided at the rear end of the bottom shell 1 is electrically connected to the battery 12, providing a charging path for the battery 12 and supplying stable electrical energy to each electronic component on the circuit board 13, including the processor 131, the photodetector 14, etc., ensuring the normal operation of each component of the device.

[0027] Example 2, based on Example 1, A photovoltaic panel 23 is fixedly installed on the top shell 2. The photovoltaic panel 23 is adhered to the top shell 2 with special photovoltaic panel glue. The photovoltaic panel 23 is electrically connected to the battery 12 through a photovoltaic charging management circuit. And a detection table 24 is installed on the top shell 2 with screws. Its function is: The photovoltaic panel 23 provides an additional charging path for the device. In an environment with light, the photovoltaic panel 23 can convert solar energy into electrical energy and store it in the battery 12, which not only increases the battery life of the device but also reduces the dependence on external power sources.

[0028] Example 3, based on Example 1 and Example 2, A transparent placement plate 241 is fixed on the detection table 24. The transparent placement plate 241 is made of high-transparency plexiglass material with a thickness of 0.5 cm, and its size matches the placement area of the detection table 24. The transparent placement plate 241 is located directly above the photodetector 14, and the distance between the two is 0.5 cm. A dust-proof cover 242 is hinged on the detection table 24. The dust-proof cover 242 is connected to the detection table 24 through a hinge. The material of the dust-proof cover 242 is the same as that of the top shell 2, which is a PC-ABS alloy material, and its surface is treated with frosting. Its function is as follows: The transparent placement plate 241 fixed on the detection table 24 is located directly above the photodetector 14, providing an accurate positioning area for the sample. This ensures that during the detection, the sample can maintain the correct relative position relationship with the photodetector 14, enabling the photodetector 14 to accurately receive the light reflected or transmitted by the sample, thereby improving the accuracy of the detection data.

[0029] The working principle of this embodiment: The user drops the collected blood sample on a specific test strip. The test strip will undergo a chemical reaction with hemoglobin in the blood, causing a corresponding change in the color of the test strip. By operating the control panel 21 on the top shell 2 to issue a detection command, after the processor 131 receives the command, it starts the device to work. At this time, the photodetector 14 starts to work. It emits light of a specific wavelength and irradiates the test strip sample placed on the transparent placement plate 241 of the detection table 24. Since the color of the test strip changes due to the hemoglobin reaction, during the process of light transmission or reflection, the characteristics such as the intensity and wavelength of the light will change. The transparent placement plate 241 ensures that the sample is always directly above the photodetector 14, ensuring that the light can accurately irradiate the sample and be effectively received by the photodetector 14 to obtain accurate optical signal change data. The photodetector 14 converts the received optical signal changed due to the sample into corresponding electrical signals. These electrical signals are transmitted through the circuit to the processor 131 on the circuit board 13. The processor 131 analyzes and processes the received electrical signal data. By comparing with the corresponding relationship data standard threshold between the pre-stored standard hemoglobin content and the optical signal change in the internal memory, based on this comparison and analysis, the accurate content of hemoglobin in the current sample is calculated. The processor 131 transmits the calculated hemoglobin content data to the display screen 22 on the top shell 2. The user can obtain the result of this hemoglobin detection by viewing the display screen 22.

[0030] In this article, the following points need to be noted: 1. The drawings of the embodiments of the present disclosure only relate to the structures involved in the embodiments of the present disclosure. Other structures can refer to the general design.

[0031] 2. Without conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other to obtain new embodiments.

[0032] The above are only specific embodiments of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present disclosure can easily think of changes or substitutions, which should all be covered within the protection scope of the present disclosure.
