Description

Technical Field

[0001] This utility model relates to the field of health monitoring technology, and more specifically, to a fixture and a spectrometer. Background Technology

[0002] Health monitoring refers to the monitoring of an individual's biological indicators, such as metabolism, blood sugar, exercise intensity, lactate levels, and hydration status, using certain technologies. Depending on the testing method, health monitoring is divided into invasive and non-invasive testing.

[0003] Traditional health monitoring methods often rely on invasive procedures. For example, blood glucose meters require blood sampling to measure blood sugar, while hydration meters assess hydration status indirectly through methods like skin conductivity. These methods are not only less portable but also carry risks of discomfort or infection. In contrast, spectroscopic analysis is a non-invasive detection method that does not require inserting sensors into the body. The spectroscopic device is simply placed manually on the area to be tested. This technology, based on the interaction between the test site and light (such as absorption, emission, or scattering), can directly acquire biometric data without damaging the body.

[0004] However, in practical applications, spectral detection and analysis technologies suffer from inconsistencies, such as variations in the measurement site, applied force, and the contact area between the device and the skin. These issues can lead to inconsistent test results, reducing the data's reference value. Utility Model Content

Detailed Implementation

[0032] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described are intended to explain this utility model and should not be construed as limiting it.

[0033] The terms "an embodiment," "example," or "trademark" used in this specification refer to a particular feature, structure, or characteristic described in connection with the embodiment itself that may be included in at least one embodiment disclosed in this utility model. The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0034] Current methods for monitoring health parameters such as blood glucose and blood oxygen using spectral detection probes typically require manual handling of the probe, placing it on the target area for a period of time before measurement. Because manual handling inevitably involves varying degrees of hand tremors and inconsistent force applied to the probe, it's impossible to guarantee accurate placement and stable contact of the probe at the same target area in every measurement. Furthermore, the inherent inconsistency in manual operation leads to instability in the measurement process, resulting in significant discrepancies between multiple measurements.

[0035] In view of the above, as a first aspect of this utility model, such as Figure 1-6 As shown, a fixture is provided, comprising a probe fixing structure 100, a fixture mounting base 200, and a position switching structure 300. The probe fixing structure 100 is used to fix a spectral detection probe 400, and the fixture mounting base 200 is used to fix the fixture to a mounting base. The mounting end 310 of the position switching structure 300 is connected to the fixture mounting base 200, and the probe fixing structure 100 is disposed at the moving end 320 of the position switching structure 300. The moving end 320 of the position switching structure 300 can drive the probe fixing structure 100 to move between a reset position 350 and a detection position 360.

[0036] The fixture described in this invention first fixes the fixture to a mounting base such as a wall or column via the fixture mounting base 200. Then, the probe fixing structure 100 clamps and fixes the spectral detection probe 400. With the precise action of the position switching structure 300, the fixture can slowly and stably move the spectral detection probe 400 to the same detection position 360 with uniform force, ensuring complete contact between the spectral detection probe 400 and the surface of the object to be detected in the detection area. During multiple measurements, the fixture described in this invention can effectively ensure the consistency of operation, thereby avoiding inconsistencies in measurement results caused by differences in operation.

[0037] The following is in conjunction with the appendix Figure 2 The position switching structure 300 for realizing uniformly moving spectral detection probe 400 is further described in detail. The position switching structure 300 includes a movable connector 340 and a plurality of mutually parallel movable parts 330. The movable connector 340 is used to connect the plurality of mutually parallel movable parts 330. The two ends of the movable parts 330 are respectively located at the mounting end 310 and the moving end 320 of the position switching structure 300. The first end of the plurality of movable parts 330 is hinged to the clamp mounting base 200, and the second end of the plurality of movable parts 330 is hinged to the probe fixing structure 100, so that the plurality of mutually parallel movable parts 330 move synchronously between the reset position 350 and the detection position 360. The moving component 330 also includes multiple guide rods 331 and multiple connecting plates 332. The multiple guide rods 331 are arranged in parallel to each other, and the two ends of the guide rods 331 are located at the first end and the second end of the moving component 330, respectively. The connecting plates 332 are sleeved on the same end of the parallel guide rods 331, and the multiple connecting plates 332 are respectively sleeved on the two ends of the parallel guide rods 331. The connecting plates 332 at the first end of the multiple moving components 330 are hinged to the clamp mounting base 200, and the connecting plates 332 at the second end of the multiple moving components 330 are hinged to the probe fixing structure 100. The movable component 330 includes multiple fixed connectors 333, one end of which is detachably hinged, and the other end of which is fixed to the connecting plate 332 by bolts. One end of the fixed connector 333 at the first end of the multiple movable components 330 is detachably hinged to the clamp mounting base 200; one end of the fixed connector 333 at the second end of the multiple movable components 330 is detachably hinged to the probe fixing structure 100. The connecting plate 332 has a connecting hole 3321 for fixing the movable connector 340. The movable connector 340 passes through the connecting hole 3321 at the first end and the connecting hole 3321 at the second end of the adjacent movable components 330, respectively.

[0038] like Figure 2The position switching structure 300 shown is a four-bar linkage structure, which includes four parallel guide rods 331, four connecting plates 332, and eight fixed connectors 333. Two guide rods 331, two connecting plates 332, and four fixed connectors 333 form a set of moving parts 330. In each set of moving parts 330, the two guide rods 331 are arranged horizontally parallel to each other. The connecting plate 332 on the left is fitted onto the left end of the two guide rods 331, and the connecting plate 332 on the right is fitted onto the right end of the two guide rods 331. Each connecting plate 332 has a fixed connector 333 bolted to both sides. The other end of the fixed connector 333 has an opening to facilitate insertion or hinge of the probe fixing structure 100 or the clamp mounting base 200. Two moving parts 330 are arranged parallel to each other in the vertical direction. One end of the spring passes through the connecting hole 3321 of the connecting plate 332 located at the left end of the upper moving part 330, and the other end of the spring passes through the connecting hole 3321 of the connecting plate 332 located at the right end of the lower moving part 330, connecting the two moving parts 330 arranged horizontally to each other in the vertical direction. The four pins of the clamping fixing plate 120 of the probe fixing structure 100 are simultaneously inserted into the openings of the four fixing connectors 333 located on the left side of the two moving parts 330, so that the clamping fixing plate 120 can rotate around the hinge point of the fixing connectors 333. The four pins of the clamp mounting base 200 are simultaneously inserted into the openings of the four fixing connectors 333 located on the right side of the two moving parts 330, so that the guide rod 331 connected to the fixing connectors 333 can move relative to the clamp mounting base 200. The two moving parts 330 are respectively arranged perpendicular to the clamping fixing plate 120 and the clamp mounting base 200. Throughout the four-bar linkage, stability during movement is maintained through the combined action of the fixed connector 333 and the spring extension / retraction. It should be noted that the clamping plate 120 and the clamp mounting base 200 can be detached from the clamp for easy maintenance or replacement depending on the application scenario.

[0039] To ensure the spectral detection probe 400 is stably fixed in the fixture and its fixed height can be flexibly adjusted, as an optional implementation, such as... Figure 3 As shown, the probe fixing structure 100 includes a probe clamping member 110 and a clamping member fixing plate 120. The clamping member fixing plate 120 has multiple fixing holes 1201, which are arranged in multiple rows and columns. The probe clamping member 110 is fixed to the fixing holes 1201 in the same row on the clamping member fixing plate 120 by bolts. The fixing holes 1201 in different rows fix the probe fixing structure 100 at different heights.

[0040] By fixing the probe holder 110 that holds the spectral detection probe 400 to the fixing holes 1201 on the clamping plate 120 of different rows, the fixed height of the spectral detection probe 400 can be flexibly adjusted to adapt to various sizes of spectral detection probes 400 and working positions.

[0041] To reduce problems such as tangling during clamping due to unreasonable layout of the signal lines 401 of the spectral detection probe 400, the moving component 330 also includes a wire clamping and fixing assembly 334. The wire clamping and fixing assembly 334 is used to fix the signal lines 401 of the spectral detection probe 400 and optimize the layout of the signal lines 401, avoiding cable crossing and tangling. As an optional implementation, such as... Figure 4 The wire clamping and fixing assembly 334 shown includes multiple wire clamps 3341 and multiple wire clamp fixing plates 3342. The multiple wire clamps 3341 and multiple wire clamp fixing plates 3342 correspond one-to-one. The wire clamps 3341 are fixedly connected to the wire clamp fixing plates 3342. The multiple wire clamp fixing plates 3342 are spaced out on the guide rods 331 that are arranged parallel to each other, and are located between the connecting plate 332 at the first end of the moving part 330 and the connecting plate 332 at the second end of the moving part 330.

[0042] Placing the signal line 401 in the wire clamp 3341, which is set along the direction of the guide rod 331, not only effectively prevents the signal lines 401 from getting tangled, but also protects the signal lines 401 from external damage, while making the direction of the signal lines 401 clearer, neater and more beautiful.

[0043] Appendix Figure 5An embodiment of the clamp provided by this utility model for clamping a spectral detection probe 400 to complete a measurement is given. The mounting end 310 of the clamp is fixed to the wall via the clamp mounting base 200. When a detection task is required, the clamp first moves the spectral detection probe 400 to the reset position 350 and waits for the object to be detected to be placed. After the object to be detected is placed in the detection area, the clamp can be released by manually applying a force to the moving end 320 of the position switching structure 300. At this time, the clamp is driven by the external force and automatically starts working. Under the combined action of the guide rod 331, the moving connector 340, the connecting plate 332, the fixed connector 333, and the probe fixing structure 100, the spectral detection probe 400 is moved downwards. During the entire movement, the position and pressure are controlled until the spectral detection probe 400 is stable at the detection position 360 and in complete contact with the part to be detected. After the measurement is completed, the clamp is manually lifted, and the clamp will automatically reset to the reset position 350 under the action of the moving connector 340. Throughout the testing process, the spectral detection probe 400 was moved slowly and steadily between the reset position 350 and the detection position 360 using a fixture with uniform force. This was unaffected by physiological tremors or arbitrary operations during manual handling, further ensuring the consistency of multiple measurement results. It is worth noting that when not performing measurements, the fixture can flexibly place the spectral detection probe 400 in any position depending on the usage scenario. For example, it could be placed at the reset position 350 for convenient use in the next measurement or on the testing table.

[0044] It should be noted that the clamp provided by this utility model can hold spectral detection probes 400 of various shapes. It is only necessary to replace the clamping part of the probe fixing structure 100 with an accessory that can fit and fix the spectral detection probe 400. A structural schematic diagram of the clamped spectral detection probe 400 in this embodiment is shown below. Figure 6As shown, the housing of the spectral detection probe 400 has an opening and a glass window 403. A signal line 401 (such as a single-mode fiber) is inserted into the spectral detection probe 400 through the opening. The optical output end of the single-mode fiber is connected to a fiber collimator 402. The fiber collimator 402 directs the light emitted from the single-mode fiber toward the glass window 403 and through the glass window 403 to illuminate the area to be detected. The light signal reflected from the area to be detected passes through the glass window 403 again and is received by multiple photodetectors 404 surrounding the fiber collimator 402. The multiple photodetectors 404 convert the optical signal into an electrical signal and transmit the electrical signal to the detector substrate 405 that fixes the photodetectors 404. Finally, the electrical signal can be output through an electrical signal transmission line electrically connected to the detector substrate 405 to complete the subsequent measurement. It should be noted that, in a spectral detection probe 400, in addition to the fiber optic collimator 402 mentioned above, the device used for collimating or changing the direction of optical signal propagation can also be a collimating lens, a self-focusing lens with a graded refractive index, or other lenses capable of controlling the light beam; the number of photodetectors 404 in the spectral detection probe 400 can be 2, 4, 5, etc., and can be adjusted according to specific needs; in addition to the glass window 403 mentioned above, any light-transmitting device that can achieve a light transmittance of more than 90% can be used to achieve the light transmission effect. Similarly, the light-transmitting device can also be coated or otherwise optimized. The shape of the light-transmitting device is not specifically limited, as long as it can achieve the incident and reflection of the light signal without reducing the loss of the light signal during transmission. For example, the shape of the light-transmitting device can be circular, square, or other shapes; the shape and height of the spectral detection probe 400 are not specifically limited, as long as it can be used in conjunction with the fixture. For example, the probe shape in this embodiment is cylindrical, but other shapes of probes can also be used.

[0045] The fixture provided by this utility model first fixes the fixture to a mounting base such as a wall or column via a fixture mounting base 200. Then, a probe fixing structure 100 clamps and fixes the spectral detection probe 400 (the probe fixing structure 100 can fix various types of spectral detection probes 400). With the precise action of the position switching structure 300, the fixture can move the spectral detection probe 400 slowly and stably to the same detection position 360 with uniform force, ensuring complete contact between the spectral detection probe 400 and the surface of the object to be detected in the detection area. During multiple measurements, the fixture of this utility model can effectively ensure the consistency of operation, thereby avoiding the problem of inconsistent measurement results caused by differences in operation. In summary, the fixture provided by this utility model has the characteristics and advantages of stable movement of the spectral detection probe 400 and consistency in multiple measurement operations.

[0046] As a second aspect of this utility model, a spectrometer is provided, which includes a light source 500, a spectral modulator 600, and a circuit module 700. The spectral modulator 600 is used to change the energy distribution of the light emitted by the light source 500 in the spectrum. The spectrometer also includes a spectral detection probe 400 fixed by a clamp provided in the first aspect. The output terminals of the circuit module 700 are connected to the light source 500 and the spectral modulator 600 to drive the light source 500 and the spectral modulator 600. The input terminals of the circuit module 700 are connected to the spectral detection probe 400 to receive the electrical signals transmitted by the spectral detection probe 400 and output the spectral information of the object to be detected.

[0047] Figure 7 This is a schematic diagram of the spectrometer structure provided by this utility model, and... Figure 7 The diagram details the propagation paths of the optical and electrical signals within the spectrometer. Circuit module 700 sends electrical signals to the light source 500 and the spectral modulator 600, driving the light source 500 to emit light and initiating operation of the spectral modulator 600. The energy distribution of the light signal emitted by the light source 500 is remodulated by the spectral modulator 600. The modulated light signal is then transmitted to the spectral detection probe 400. The spectral detection probe 400 illuminates the object to be detected with the light signal and receives the light signal reflected back from the object. After converting the light signal into an electrical signal, the spectral detection probe 400 outputs it to circuit module 700. Circuit module 700 processes the electrical signal and calculates the spectral information of the object to be detected. The light source 500 of the spectrometer can be a superluminescent diode or other broadband light source 500.

[0048] It should be noted that the circuit modulation module includes a drive module 701 and a signal processing module 702, such as... Figure 8 As shown. The driving module 701 is used to drive the light source 500 and the spectral modulator 600; the signal processing module 702 is connected to the signal transmission wire of the spectral detection probe 400, and obtains the spectral information of the object to be detected based on the electrical signal transmitted by the signal transmission wire.

[0049] A spectral modulator 600 is positioned between the light source 500 and the spectral detection probe 400 to alter the energy distribution of the light emitted by the light source 500 across the spectrum. As an optional implementation, such as... Figure 9 As shown, the spectral modulator 600 includes a multi-stage active tunable spectral unit 601, with the output of the previous stage active tunable spectral unit 601 connected to the input of the next stage active tunable spectral unit 601.

[0050] Figure 10The given spectral modulator 600 consists of four active tunable spectral units 601. The first active tunable spectral unit 601 is an asymmetric Mach-Zehnder interferometer, with a phase modulator 6011 on each of its interferometer arms. The second to fourth active tunable spectral units 601 are microring resonators, each with a different ring length and a phase modulator 6011. The optical signal is transmitted through an optical waveguide to two interferometer arms of the asymmetric Mach-Zehnder interferometer. By changing the parameters of the phase modulators 6011 on the interferometer arms, the phase difference / optical path difference between the two interferometer arms is altered, causing interference between the two optical signals at the optical waveguide, thus controlling the intensity of the optical signal. The optical signal processed by the Mach-Zehnder interferometer enters the microring structure, where the microring performs wavelength selection on the input optical signal, coupling a specific wavelength of optical signal to the microring. Through the synergistic effect of the two, flexible tuning and control of various parameters of optical signals (such as wavelength and intensity) can be achieved.

[0051] In addition to the spectral modulator 600 Figure 10 In addition to the given embodiments, the structure can also be a cascaded Mach-Zehnder interferometer or a cascaded microring.

Those skilled in the art should understand that this utility model includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
