Description

Technical Field

[0001] This application belongs to the field of medical testing device technology, and more specifically, relates to a probe device and its detector for detecting the concentration of components in chaotic media. Background Technology

[0002] Currently available medical devices for detecting the concentration of chaotic media components, such as transcutaneous jaundice monitors for detecting neonatal jaundice levels, are typically handheld, press-type devices. These devices require manual operation, needing to be pressed once per measurement, and cannot provide automatic real-time monitoring. This means medical staff cannot continuously monitor changes in jaundice levels over extended periods; in other words, existing handheld press-type devices do not solve the problem of automatically monitoring patients' jaundice levels. Furthermore, the probes used in these handheld devices are reusable, posing a risk of cross-infection. In addition, the probes and other components of existing transcutaneous jaundice monitors are fixedly connected as a single unit, requiring the development of both the display and the entire device, resulting in complex installation and high costs.

Furthermore, by prolonged attachment to the skin, automatic real-time monitoring can be achieved, allowing medical personnel to continuously observe changes in jaundice values, thus meeting the need for automatic jaundice monitoring. Simultaneously, because the light source and photoelectric sensor are arranged on the same plane and attached to the skin, the diffusely reflected light emitted by the light source penetrates the skin surface and, after multiple scattering and absorption, is better collected by the photoelectric sensor, resulting in a more effective photoelectric signal. Since both the light source and photoelectric sensor are stationary during measurement, the accuracy and stability of transdermal detection are effectively improved.

[0050] The embodiments of this application 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 below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0051] This application provides a probe device for detecting the concentration of components in chaotic media.

[0052] Please see Figures 1 to 8In the first embodiment, the probe device for detecting the concentration of chaotic media components (hereinafter referred to as the probe device) is suitable for a detector for detecting the concentration of chaotic media components via skin testing (hereinafter referred to as the detector). Specifically, the probe device for detecting the concentration of chaotic media components includes a flexible carrier 100, a data transmission component 200, and a circuit layer 300. The flexible carrier 100 is made of a flexible material and is in the form of a flexible sheet that can be attached to the skin. The data transmission component 200 includes an interconnected PCB board 210 and a data interface 220. The circuit layer 300 is installed in the flexible carrier 100 and includes a light source 310, a photoelectric sensor 320, and a flexible plate 330. Several light sources 310 and several photoelectric sensors 320 are installed on the side of the flexible carrier 100 away from the data transmission component 200, and the light sources 310 and photoelectric sensors 320 are located on the same plane; one end of the flexible plate 330 is connected to the light source 310 and the photoelectric sensor 320, and the other end of the flexible plate 330 is connected to the PCB board 210. The flexible carrier 100, with the light source 310 and photoelectric sensor 320 mounted on one side, can be attached to the skin by pasting or wrapping. The light source 310 emits light that shines onto the skin, and the photoelectric sensor 320 converts the light signal reflected back from the skin into an analog electrical signal. The PCB board 210 connects the flexible board 330 to the data interface 220 or converts the analog electrical signal transmitted through the flexible board 330 into a digital signal via A / D conversion. The data interface 220 transmits the analog electrical signal or digital signal to the microcontroller motherboard of the detector for detecting the concentration of chaotic media components connected to it.

[0053] Based on this design, in this embodiment, since the flexible carrier 100, which houses the light source 310 and photoelectric sensor 320 in the probe device for detecting the concentration of chaotic media components, is in the form of a flexible sheet, the probe device for detecting the concentration of chaotic media components can easily obtain data on the concentration of chaotic media components detected transdermally after being attached to the skin. This data includes, but is not limited to, transdermal jaundice values. Moreover, by being attached to the skin for an extended period, automatic real-time monitoring can be achieved. In this way, medical personnel can continuously observe changes in jaundice values, meeting the need for automatic jaundice monitoring. Simultaneously, since the light source 310 and photoelectric sensor 320 are arranged on the same plane and attached to the skin, the light emitted by the light source 310 penetrates the skin surface and, after multiple scattering and absorption, is reflected to form diffuse light, which can be better collected by the photoelectric sensor 320, thereby obtaining a more effective photoelectric signal. Since both the light source 310 and photoelectric sensor 320 are stationary during measurement, the accuracy and stability of transdermal detection can be effectively improved. Furthermore, this probe device for detecting the concentration of chaotic media components can be made into a disposable probe or a reusable probe, and has comprehensive advantages such as simple structure, better overall integration, convenient installation, reduced materials, low assembly labor costs, good product consistency, and convenient and more stable product use.

[0054] It should be noted that the chaotic media components to be detected in this application include, but are not limited to, the concentration of bilirubin in the skin and blood, i.e., the jaundice value is detected. Transdermal detection of blood oxygen, blood lipids, and other suitable components can also be achieved by setting different types or parameters of the light source 310 and the corresponding photoelectric sensor 320. In practical use, taking the monitoring of neonatal jaundice values ​​as an example, first connect the data interface 220 of the probe device for detecting the concentration of chaotic media components to the corresponding detector for detecting the concentration of chaotic media components. Then, fix the end of the probe device for detecting the concentration of chaotic media components, which is equipped with the light source 310 and the photoelectric sensor 320, to the user's skin. After the detector is powered on, the light emitted by the light source 310 penetrates the skin at the detection site and, after multiple scattering and absorption within the skin, forms diffuse reflection light. This diffuse reflection light is collected by the photoelectric sensor 320 located next to the light source 310 and converted into analog electrical signals. These analog electrical signals are transmitted through the relevant circuits on the flexible board 330 to the PCB board 210 at the other end. The PCB board 210 can directly transmit the analog electrical signals to the data interface 220, and then through the data interface 220 to the microcontroller motherboard of the detector. Alternatively, the PCB board 210 can first perform A / D conversion to convert the analog electrical signals into digital signals, and then these digital signals are transmitted through the data interface 220 to the microcontroller motherboard of the detector connected to it, and finally displayed on the display screen of the detector. In other words, this probe device, as part of the detector, is a detachable and separate design from the main body of the detector. Compared with the currently common handheld press-type jaundice detectors, this probe device involves fewer materials, has a simpler structure, and lower assembly costs, making the product very convenient to install and use.

[0055] Please see Figures 1 to 8Specifically, in this embodiment, the flexible carrier 100 includes an outer layer 110 and a liner 120 connected vertically, with a flexible plate 330 sandwiched between the outer layer 110 and the liner 120. The liner 120 includes an integrally connected probe region 121 and a connecting region 122. The connecting region 122 is a flexible elongated strip, with one end integrally connected to the probe region 121 and the other end extending into the data transmission assembly 200. The probe region 121 has a first through hole 123 for preventing the light source 310 and photoelectric sensor 320 from entering. The light source 310 and photoelectric sensor 320 are both welded to the flexible plate 330, and the light source 310 and photoelectric sensor 320 are exposed downwards from the first through hole 123. The flexible plate 330 extends from above the probe region 121, through the connecting region 122, and into the data transmission assembly 200. Here, multiple related circuits are etched on the flexible board 330. The light source 310 and the photoelectric sensor 320 are electrically connected to their respective circuits by soldering through corresponding pins. In this way, the microcontroller motherboard of the detector can control the light source 310 to turn on or off, and the analog electrical signal collected by the photoelectric sensor 320 can be successfully transmitted to the PCB board 210 at the other end of the probe device for further processing or transmission. The outer layer 110 and the liner 120 are made of flexible materials, which can be the same or different. The outer layer 110 and the liner 120 are basically the same in shape, and their outer edges can be connected by means of, but not limited to, hot pressing or bonding. The flexible board 330, the light source 310, and the photoelectric sensor 320 are all sandwiched between the outer layer 110 and the liner 120, and the first through hole 123 allows the light source 310 to emit light downwards for transdermal detection, and the photoelectric sensor 320 can also collect the relevant diffuse reflected light. Furthermore, in this embodiment, the probe area 121 is square. Of course, in other embodiments, the probe area 121 may also be circular or other shapes, and no particular limitation is made here.

[0056] It should be noted that this probe device for detecting the concentration of components in chaotic media has at least two usage forms: First, this probe device is a disposable probe device. This disposable design effectively avoids the risk of cross-infection. In this case, for cost reduction, the outer layer 110 can be made of a low-cost material, such as, but not limited to, non-woven fabric or cloth. Second, this probe device is a reusable probe device. In this case, the outer layer 110 can be made of silicone or silicone rubber. Of course, in other embodiments, the outer layer 110 can also be made of other suitable flexible materials, but the silicone material in this embodiment has advantages such as being soft and skin-friendly, heat-resistant, and corrosion-resistant, making it more suitable for the design of medical device products.

[0057] Specifically, such as Figure 4 and Figure 8As shown, the data transmission component 200 also includes an interface housing 230. A PCB board 210 is built into the interface housing 230. One end of the flexible board 330, away from the light source 310, extends into the interface housing 230 and connects to the PCB board 210. One end of the data interface 220 is built into the interface housing 230 and connected to the other end of the PCB board 210 away from the flexible board 330. The other end of the data interface 220 extends out of the interface housing 230. Here, the interface housing 230 mainly serves to protect the internal electrical components and also acts as a convenient handheld end. The interface housing 230 is also provided with several ribs 231 for easy gripping. The PCB board 210 and the data interface 220 are usually integrated to achieve stable electrical signal transmission. In this embodiment, the data interface 220 is preferably a USB interface. However, this design is not limited to this. In other embodiments, the data interface 220 can be other types of interfaces. But in this embodiment, the USB interface not only meets the information transmission requirements but also has high versatility.

[0058] Furthermore, such as Figure 2 , Figures 6 to 8 As shown, the flexible carrier 100 also includes an adhesive layer 130, which is located below the probe area 121 and has a second through hole 131 corresponding to the position of the first through hole 123. The upper surface of the adhesive layer 130 is bonded to the lower surface of the probe area 121, and the lower surface of the adhesive layer 130 can be adhered to the skin. Specifically, in this embodiment, the adhesive layer 130 is a double-sided adhesive layer, that is, the upper surface of the adhesive layer 130 is bonded to the lower surface of the probe area 121 of the liner 120, and the lower surface of the adhesive layer 130 is provided with release paper. When the probe device needs to be used, the release paper can be peeled off first, and then the lower surface of the adhesive layer 130 can be adhered to the skin. In this way, the detection end of the probe device, which is equipped with the light source 310 and the photoelectric sensor 320, can be firmly fixed to the skin, thereby realizing long-term automatic real-time monitoring. Of course, in other embodiments, the adhesive layer 130 can also be configured in other ways, which are not particularly limited here. In addition, in other embodiments, the flexible carrier 100 may not include the adhesive layer 130. For example, when the probe device is for reusable use, the outer layer 110 and the liner 120 made of silicone are attached to the skin in the probe area 121 and then secured by medical tape or rope.

[0059] Please see Figure 2 , Figures 6 to 8In this embodiment, the flexible carrier 100 further includes a light-transmitting protective layer 140 made of a transparent, soft material. The light-transmitting protective layer 140 is located between the probe region 121 and the adhesive layer 130, and covers the second through-hole 131. Light emitted by the light source 310 passes through the light-transmitting protective layer 140 and exits through the second through-hole 131. It is understood that, relative to the sheet-like flexible carrier 100, both the light source 310 and the photoelectric sensor 320 have a certain thickness. If the light-transmitting protective layer 140 is not provided, the protruding edges of the light source 310 and the photoelectric sensor 320 may cause skin scratches. The light-transmitting protective layer 140 effectively avoids this problem. Here, the light-transmitting protective layer 140 is typically a transparent plastic sheet to balance light transmission, protection, and flexibility. Of course, in other embodiments, the light-transmitting protective layer 140 may not be provided, and probe devices without the light-transmitting protective layer 140 are also within the scope of protection of this application.

[0060] It should be noted that in the technical solution of this application, the light source 310 is a multi-color LED that includes at least blue and green light, and the photoelectric sensor 320 is a photoelectric sensor without a filter; or, the light source 310 is a white LED, and the photoelectric sensor 320 is a multi-color photoelectric sensor with multi-color filters that includes at least blue and green light filters. Specifically, in this embodiment, the light source 310 is an RGB multi-color LED, that is, an LED that encapsulates blue, green, and red light together. The photoelectric sensor 320 is also called a PD, photoelectric sensor, or silicon photodiode, etc. When this probe device is used to detect jaundice values, since bilirubin has good light absorption at a wavelength of 460nm blue light, while its light absorption at a wavelength of 550nm green light is almost zero, the light source 310 and the photoelectric sensor 320 should include blue light. It should be noted that in this application, 460nm represents the blue light band, but the actual wavelength of blue light is not limited to 460nm, and can also be 455nm, etc.; 550nm represents the green light band, but the actual wavelength of green light is not limited to 550nm, and can also be 549nm, etc.; similarly, 630nm represents the red light band, but the actual wavelength of red light is not limited to 630nm, and can also be 629nm, etc.

[0061] Here, on the plane where the light source 310 and the photoelectric sensor 320 are located, with the length direction of the liner 120 and the flexible plate 330 as the left and right direction and the width direction of the liner 120 and the flexible plate 330 as the up and down direction, the positions of the light source 310 and the photoelectric sensor 320 can be arranged in various ways.

[0062] In Method 1, when the light source 310 is packaged as a multi-color LED and the photoelectric sensor 320 is a filterless photoelectric sensor, the light source 310 is located beside the photoelectric sensor 320. For example, in Figure 2 and Figure 8 In the first embodiment shown, there is one light source 310 and one photoelectric sensor 320. The light source 310 is a multi-color LED encapsulated with RGB colors. The light source 310 and the photoelectric sensor 320 are placed side-by-side in a vertical direction, with the light source 310 located above the photoelectric sensor 320. In... Figure 9 In the second embodiment shown, there is also one light source 310 and one photoelectric sensor 320. The light source 310 is a multi-color LED with RGB three colors encapsulated. The light source 310 and the photoelectric sensor 320 are placed side by side in the left-right direction, with the light source 310 located to the right of the photoelectric sensor 320. Of course, in other embodiments, the light source 310 may also be located below or to the left of the photoelectric sensor 320, etc.

[0063] Method Two: When the light source 310 is packaged from a multi-color LED, and the photoelectric sensor 320 consists of two photoelectric sensors without filters, the two photoelectric sensors 320 are arranged linearly or non-linearly with the light source 310. Both photoelectric sensors 320 are located on the same side or on opposite sides of the light source 310, and the distance between the center of the two photoelectric sensors 320 and the center of the light source 310 is not the same; that is, one of the photoelectric sensors 320 is closer to the light source 310, while the other is farther away. This allows for better removal of the influence of melanin. For example, in... Figure 13 In the sixth embodiment shown, a light source 310 and two photoelectric sensors 320 are arranged sequentially in a vertical direction. The light source 310 is a multi-color LED encapsulated with green and blue light. The light source 310 is located above the two photoelectric sensors 320. The distance between the center of the upper photoelectric sensor 320 and the center of the light source 310 is smaller than the distance between the center of the lower photoelectric sensor 320 and the center of the light source 310. Figure 14 In the seventh embodiment shown, two photoelectric sensors 320 and a light source 310 are arranged sequentially in a left-right direction. The light source 310 is also a multi-color LED encapsulated with green and blue light. The light source 310 is located to the right of the two photoelectric sensors 320. The distance between the center of the photoelectric sensor 320 on the right and the center of the light source 310 is smaller than the distance between the center of the photoelectric sensor 320 on the left and the center of the light source 310. Of course, in other embodiments, the light source 310 may also be located below or to the left of the two photoelectric sensors 320, etc.

[0064] Method 3: When the light source 310 is a multi-color LED, the photoelectric sensor 320 is a filterless photoelectric sensor, and there are multiple light sources 310 and only one photoelectric sensor 320, the multiple light sources 310 are evenly arranged around the photoelectric sensor 320.
