DETAILED DESCRIPTION

[0033] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0034] In the description of the present invention, it should be understood that the terms "longitudinal", "radial", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0035] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] In one embodiment, if Figure 1-3 As shown, a probe structure for jaundice detection comprises a first circuit board 2, a second circuit board 3, a first circuit board 4, an emission light guide column 5, a first reflection light guide column 6 and a second reflection light guide column 7 which are sequentially installed in a housing, wherein the first reflection light guide column 6, the emission light guide column 5 and the second reflection light guide column 7 are sequentially arranged from the inside to the outside and are coaxially sleeved, and the first circuit board 2, the second circuit board 3 and the first circuit board 4 are sequentially connected along the length direction of the probe housing 1;

[0037] The emitting end of the emitting light guide column 5 passes through the first circuit board 2 and is arranged corresponding to the light source component 8 installed on the second circuit board 3; the receiving end of the first reflecting light guide column 6 passes through the first circuit board 2 and the second circuit board 3 in sequence, and is arranged corresponding to the first sensor component 9 installed on the third circuit board 4; the second reflecting light guide column 7 is arranged corresponding to the second sensor component 10 installed on the first circuit board 2.

[0038] Among them, the emitting light guide column 5 is responsible for transmitting the light of a specific wavelength emitted by the light source component 8 to the skin surface, the first reflecting light guide column 6 and the first reflecting light guide column 7 receive the light reflected, scattered and refracted by the subcutaneous tissue of the skin, and convert it into an electrical signal through the first sensing component 9 and the second sensing component 10, and the intensity and wavelength of the light reflected back by the first reflecting light guide column 6 and the first reflecting light guide column 7 are measured by the electrical signal to evaluate the color change of the skin, and the presence of jaundice is determined according to the change of the spectrum reflected by the skin due to the deposition of bilirubin. The number of the second reflecting light guide columns 7 can be set to multiple according to the needs, and the multiple first reflecting light guide columns 7 are sequentially connected to the emitting light guide column 5 to offset the influence of skin melanin, and the first reflecting light guide column 6 is used to detect the jaundice value. Furthermore, the first reflective light guide column 6, the emitting light guide column 5 and the second reflective light guide column 5 can all be made of optical plastics such as acrylic transparent material PMMA, polycarbonate, epoxy resin, etc. by injection molding, so that the above three light guide columns have excellent light transmittance and stable physical properties, ensuring that the optical signal will not be significantly attenuated due to material absorption or scattering during transmission, thereby improving the precision and accuracy of jaundice detection.

[0039] In the present invention, the subtlety of the probe structure lies in its unique modular and layered layout concept. By cleverly connecting three carefully designed first circuit boards 2, second circuit boards 3 and third circuit boards 4 in series along the longitudinal axis of the probe housing 1, not only a high degree of space optimization is achieved, the overall integration density is significantly improved, but also close cooperation and efficient data transmission between the functional modules are ensured. At the same time, the introduction and layered setting of the three light guides further strengthen the modular characteristics of the structure, so that each key component can be independently installed and quickly replaced, which greatly simplifies the subsequent maintenance process and assembly operations, reduces maintenance costs, and improves work efficiency. This design philosophy not only reflects the ultimate pursuit of technical details, but also demonstrates a deep insight into user experience and equipment reliability. Therefore, the present invention not only greatly improves the integration and installation convenience of the probe structure, but also brings more outstanding performance, higher operating stability and more humanized user operation experience to the overall equipment, which is an important step in promoting technological progress and industrial upgrading in related fields.

[0040] In one embodiment, if Figure 1 As shown, the first reflecting light guide column 6, the emitting light guide column 5 and the third reflecting light guide column 5 are all arranged to be a trumpet-shaped or cone-shaped structure with one end small and the other end large, which can not only adapt to the layout requirements of the multi-layer optical path (the layout requirements of the sensor and the LED light group), but also reduce the reflection and scattering losses of light in the transmission process, so that more light can be focused on the detection area. The trumpet-shaped or cone-shaped light guide columns can also reduce the interference of external ambient light on the measurement results to a certain extent.

[0041] In one embodiment, if Figure 1 and Figure 2 As shown, the housing includes a first housing 101, a first housing 102, a third housing 103, and a fourth housing 104 plugged into the first housing 101, the fourth housing 104 is wrapped around the outside of the emitting end of the second reflective light guide column 7, the first circuit board 2 is installed in the first housing 101, the second circuit board 3 is installed in the second housing 102, and the first circuit board 4 is installed in the third housing 103. Understandably, the first circuit board 2, the first circuit board 3, and the third circuit board 4 are installed in sequence along the length direction of the probe housing 1 and divide the accommodating cavity into three independent installation cavities, namely the first installation cavity, the second installation cavity, and the third installation cavity, the receiving end of the first reflective light guide column 6 is located in the second installation cavity, the emitting end of the emitting light guide column 5 is arranged through the first circuit board 2 and is located in the first installation cavity, and the emitting light guide column 5 and the first reflective light guide column 6 are respectively installed in different installation cavities, thereby realizing the physical isolation of the optical path and the circuit board. Furthermore, the first shell 101 forms a first installation cavity, the second shell 102 forms a second installation cavity, and the third shell 103 forms a third installation cavity. The first shell 101, the second shell 102 and the first shell 103 constitute the probe shell 1, which can protect various circuit boards and optical components; the split design of the probe shell 1 is convenient for maintenance and replacement, and also helps to achieve clear distinction of functions.

[0042] In one embodiment, if Figure 2 As shown, the probe structure for jaundice detection further includes a positioning plate 11 installed between the first reflective light guide column 7 and the first circuit board 2, and the first circuit board 2 presses the positioning plate 11 and is fixedly installed on the first housing 101 by bolts. It can be understood that the positioning plate 11 effectively blocks part of the redundant reflected light, and cooperates with the first circuit board 2 to further prevent these lights from entering the cavity where the first circuit board 2 is located, thereby reducing light interference.

[0043] In one embodiment, if Figure 1 and Figure 2 As shown, the second reflective light guide column 7 also includes two bosses (not shown) symmetrically arranged at the receiving end of the first reflective light guide column 7, and the positioning plate 11 is provided with a positioning hole adapted to the boss. The positioning plate 11 is provided with a positioning hole adapted to the boss, so that the boss is accurately embedded in the positioning plate 11 to avoid optical path deviation caused by installation error. The boss can also accurately guide the reflected light to the corresponding second sensor component 10, and the two symmetrically arranged bosses help maintain the symmetry of the optical path, so that the intensity of the optical signal received by the second sensor component 10 is more balanced.

[0044] In one embodiment, if Figure 1 and Figure 2 As shown, the second sensing assembly 10 includes a second sensor (not shown) and a third sensor (not shown). In order to meet the installation requirements of the second sensor and the third sensor (whose layout is strictly limited by the external dimensions and circuit pad packaging), and simultaneously avoid the problem of increased probe thickness caused by placing the second sensor and the third sensor up and down, the second sensor and the first sensor are arranged on the left and right, so that the thickness of the probe can be effectively controlled to be kept within a relatively reasonable and aesthetic range. To adapt to the above layout, the outer contour of the receiving end of the second reflective light guide column 7 can be designed to be elliptical, which can not only meet the installation requirements, but also optimize the optical path to a certain extent and improve the utilization rate of light.

[0045] In another embodiment, if Figure 1 and Figure 2 As shown, the boss is arranged opposite to the second sensor or the third sensor, and the center of the boss is arranged opposite to the center of the second sensor or the collection window of the second sensor, and the cross-sectional area of ​​the boss is larger than the cross-sectional area of ​​the collection window (light receiving window) of the second sensor or the third sensor. Understandably, the relative arrangement and area difference design of the boss and the sensor enable the reflected light to directly and efficiently enter the collection window. The boss with a larger cross-sectional area can capture more reflected light and guide it to the collection window, which not only increases the receiving area of ​​the light signal, reduces the scattering and loss of light, but also improves the sensor's sensitivity and receiving ability to the light signal.

[0046] In one embodiment, if Figure 1 As shown, the light source assembly 8 includes a plurality of blue LEDs, a plurality of green LEDs, and a plurality of red LEDs arranged on the second circuit board 3. It is understandable that the second circuit board 3 is arranged opposite to the emitting end of the emitting light guide column 5, that is, the plurality of blue LEDs, a plurality of green LEDs, and a plurality of red LEDs of the light source assembly 8 are arranged opposite to the emitting end of the emitting light guide column 5, so that the light emitted by the light source assembly 8 can directly irradiate the emitting end of the emitting light guide column 5, reducing the loss and scattering of the light in the propagation process. The light emission direction of the light source assembly 8 is perpendicular to the emitting end of the emitting light guide column 5, which helps to reduce the angle deviation of the light at the time of incidence, improve the efficiency of the light entering the emitting light guide column 5, and promote the uniform distribution of light intensity at the emission end.

[0047] In one embodiment, if Figure 1 As shown, there is a certain distance between the emitting end of the emitting light guide column 5 and the lamp beads of each LED of the light source group, which enhances the uniformity of the red, green and blue lights. If the red, green and blue lamp beads are too close, the intensity is good but the uniformity is poor. Maintaining a certain distance can not only ensure the intensity of the emitted light, but also enhance the uniformity of the emitted light.

[0048] In one embodiment, if Figure 3 As shown, the first circuit board 2, the second circuit board 3 and the third circuit board 4 are connected by welding through several groups of 5pin pin headers 12. Understandably, the use of several groups of 5pin pin headers 12 to weld the second circuit board 4, the second circuit board 3 and the first circuit board 2 shows multiple advantages. First, the presence of the solder joints firmly fixes the first circuit board 2, the second circuit board 3 and the third circuit board 4 together to form a stable whole, effectively resisting the influence of external factors such as vibration and impact on the stability of the circuit board connection, and preventing the occurrence of looseness or separation. Secondly, this welding connection method ensures the reliable transmission of electrical signals between the three circuit boards. Each group of 5pin pin headers 12 is accurately connected to the corresponding pads, forming a low-impedance, high-stability electrical path, ensuring the integrity and accuracy of the signals between the three circuit boards. Furthermore, the use of 5pin pin headers 12 for circuit board connection also significantly simplifies the assembly process and improves production efficiency. The design of the pin header makes the alignment between the circuit boards intuitive and easy to operate, reducing the complexity and human errors in the assembly process, while also shortening the assembly time and improving the overall work efficiency.

[0049] In one embodiment, if Figure 1 As shown, a copper ring 13 is sleeved between the emission light guide column 5 and the first reflection light guide column 7. Understandably, the metal ring can be a copper ring 13, and the metal ring can increase the distance of the second reflection light path (long light path). The increased distance is the thickness of the metal ring, which can change the path length and attenuation characteristics of the light during the propagation process, thereby affecting the intensity and quality of the final received light signal; by mixing and calculating the signals of the first reflection light path (short light path) and the second reflection light path (long light path), the different absorption characteristics of the two for different components (such as bilirubin and melanin) when penetrating the skin are utilized to effectively remove or reduce the influence of melanin on the measurement results.

[0050] In one embodiment, the outer surfaces of the emission light guide column 5, the first reflection light guide column 6 and the second reflection light guide column 7 are all provided with electroplating layers. It can be understood that the provision of the electroplating layer can isolate the first reflection light path, the emission light path and the first reflection light path, further avoiding interference between the light paths, and each light path can propagate independently to ensure the stability and accuracy of the optical signal; the electroplating layer also provides a protective layer for the surface of the light guide column to prevent it from being eroded and damaged by the external environment.

[0051] In one embodiment, a sealing layer is provided at the connection between the first circuit board 2 and the emitting light guide column 5, the connection between the second circuit board 3 and the first reflecting light guide column 6, the connection between the first circuit board 2 and the first shell 101, the connection between the second circuit board 3 and the second shell 102, and the connection between the second circuit board 4 and the second shell 103. Understandably, by providing a sealing layer at the connection between the circuit board and the light guide column and the circuit board and the shell, the sealing layer improves the sealing between the cavities, eliminates the risk of light leakage pollution caused by light penetration from the connection, and the enhanced structural stability ensures the firmness of the connection and prevents displacement or dislocation caused by external force. At the same time, the sealing layer effectively prevents the intrusion of external factors such as moisture and dust, and prolongs the service life of the equipment. The introduction of the sealing layer also simplifies the assembly process, reduces the difficulty of assembly, improves production efficiency, and reduces maintenance costs and simplifies maintenance work. .

[0052] The present invention also provides a method for installing a probe structure for jaundice detection, wherein the method is to install the above-mentioned probe structure for jaundice detection, and comprises the following steps:

[0053] S1.

[0054] S2. Install the second reflective light guide column 7, apply glue to the outer layer of the second reflective light guide column 7 and the inner layer of the fourth shell 104 respectively, and insert the second reflective light guide column 7 into the fourth shell 104; the glue treatment in this step ensures the fixation of the light guide column and also helps to reduce the loss of light at the interface.

[0055] S3, installing the positioning plate 11, and installing the positioning plate 11 into the first housing 101; the use of the positioning plate 11 provides an accurate position reference for the subsequent installation of the circuit board, ensuring the correct alignment of the circuit board and other components.

[0056] S4, soldering the pin headers 12 to the first circuit board 2, preparing several groups of 5-pin pin headers 12, and soldering the 5-pin pin headers 12 to the first circuit board 2; this step provides a standardized interface for electrical connection between circuit boards, facilitating subsequent connection and maintenance.

[0057] S5, install and fix the first circuit board 2, and fix the first circuit board 2 with the pin header 12 to the first housing 101 through four bolts. This step ensures the stable installation of the first circuit board 2 and provides guarantee for the electrical performance of the entire probe.

Install the emitting light guide column 5, apply glue to the front end outer layer of the emitting light guide column 5 and the front end of the second reflecting light guide column 7 respectively, and insert the emitting light guide column 5 into the inner layer of the second reflecting light guide column 7; this step helps to fix the emitting light guide column 5 and reduce the scattering of light at the interface.

[0059] S7, installing the second shell 102 of the probe, and installing the second shell 102 on the first shell 101; this step further constructs the outer shell structure of the probe, providing additional protection for the internal components of the probe structure.

[0060] S8. Install and solder the second circuit board 3, pass the 5-pin headers 12 soldered on the first circuit board 2 through the soldering holes on the first circuit board 3, and install the first circuit board 3 in the first housing 102 and solder it in place; this step completes the stable installation of the second circuit board 3.

[0061] S9. Install the first reflective light-guiding column 6, perform glue treatment on the front end outer layer of the first reflective light-guiding column 6, pass the first reflective light-guiding column 6 through the second circuit board 3 and insert it into the inner layer of the emitting light-guiding column 5; the glue treatment in this step and the precise matching between the first reflective light-guiding column 6 and the first circuit board 3 ensure the fixation of the light-guiding column and the correctness of the optical path.

This step completes the final connection between the circuit boards and ensures the stable installation of the circuit boards.

[0064] In the above steps of the present invention, the design of step-by-step installation effectively reduces the complexity of one-time processing and improves the manageability of the installation process by breaking down the entire installation process into steps that focus on a single or a few components.

[0065] The present invention uses dispensing in multiple key steps, such as S1, S2 and S9, to ensure a firm connection between components, while providing elasticity to absorb vibration and thermal expansion, thereby enhancing the stability of the overall structure. The use of the positioning plate 11 is particularly critical in step S3, ensuring the precise placement and alignment of the circuit board and other components, and improving the installation accuracy. The standardized operation of the 5-pin pin header 12 simplifies the complexity of the connection of the three circuit boards in steps S4, S8 and S11, and provides a reliable method for the electrical connection between the three circuit boards.

[0066] The modular installation of the present invention is achieved through steps S5, S8 and S11, so that the installation of different circuit boards and light guides becomes independent, which is convenient for individual replacement or upgrading, thereby improving the convenience of maintenance. The step-by-step assembly process in steps S6, S7, S9 and S10 allows the installation quality of each component to be gradually checked and tested, which helps to find and solve problems in a timely manner. The use of precise dispensing and positioning plates 11 reduces the need for manual adjustment of components during installation and reduces the possibility of human error.

[0067] In addition, the step-by-step installation method provides the possibility for future automated installation, which can be performed by robots or automated equipment, further improving installation efficiency and consistency.
