Description

Technical Field

[0001] This utility model relates to the field of monitoring equipment technology, and more specifically, to a jaundice monitoring device. Background Technology

[0002] Neonatal jaundice is a common clinical condition. Traditional jaundice detection devices mainly use rare gas (xenon) lamps as the light source, which are activated by high-voltage equipment to emit xenon light for detection. This method has significant limitations: First, xenon lamps are large and require high-voltage power, which is not conducive to the miniaturization and portability of the device; second, traditional devices can only perform single-point measurements and cannot achieve continuous monitoring, making it difficult to accurately reflect the development and changes in jaundice; more importantly, when the user receives blue light therapy, the therapeutic blue light is absorbed by the skin, leading to deviations in the test results and affecting the accuracy of clinical judgment. Utility Model Content

[0003] The problem this invention addresses is: how to improve the convenience and continuity of jaundice monitoring.

[0004] To address the aforementioned problems, this utility model provides a jaundice monitoring device comprising an attachment shell and a monitoring structure. The monitoring structure includes a circuit board and blue LEDs, green LEDs, and a light signal converter mounted on the circuit board. The monitoring structure is housed within the attachment shell, which is designed to adhere to the user's skin. The blue light emitted by the blue LEDs and the green light emitted by the green LEDs can penetrate the user's skin. The light signal converter receives the blue and green light reflected from the user's skin and is used for communication with a host computer.

[0005] Optionally, the adhesive shell includes a first sidewall and a perforation. The first sidewall is used to adhere to the user's skin, and the perforation is disposed on the first sidewall. The blue LED, the green LED, and the light signal converter are recessed into the perforation.

[0006] Optionally, a limiting groove is provided at one end of the limiting seat away from the first sidewall, the opening of the limiting groove is away from the first sidewall, the limiting groove is connected to the first through hole and the second through hole respectively, and the monitoring structure is snapped into the limiting groove.

[0007] Optionally, the attachment housing is made of soft silicone material.

[0008] Optionally, the number of blue LEDs and the number of green LEDs are equal.

[0009] Optionally, the attachment shell is configured as a cuboid shape, and the edges of the attachment shell are provided with rounded chamfers.

[0010] Optionally, the attachment housing includes a wiring channel for connecting to a signal line, and the light signal converter is wired to the host computer.

[0011] Optionally, the sidewall of the attached housing opposite to the first sidewall protrudes in a direction away from the first sidewall.

[0012] Optionally, the outer surface of the limiting seat is provided with anti-slip protrusions.

[0013] Compared with existing technologies, the jaundice monitoring device of this invention replaces the traditional rare gas (xenon) lamp with blue and green LEDs, achieving miniaturization of the monitoring light source. Furthermore, because the outer casing is oriented towards the user, allowing it to adhere to the user's skin, it can remain in contact with the user's skin throughout the jaundice treatment process, enabling 24-hour dynamic monitoring. This achieves continuous jaundice monitoring, improving the convenience and sustainability of jaundice monitoring. Attached Figure Description

[0018] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this utility model described herein can be implemented in sequences other than those illustrated or described herein.

[0019] Combination Figures 1 to 3 As shown, a jaundice monitoring device according to an embodiment of the present invention includes an attachment shell 1 and a monitoring structure 2. The monitoring structure 2 includes a circuit board and blue LED 21, green LED 22 and light signal converter 23 mounted on the circuit board. The monitoring structure 2 is fitted inside the attachment shell 1, which is used to adhere to the user's skin. The blue light irradiated by the blue LED 21 and the green light irradiated by the green LED 22 can penetrate the user's skin. The light signal converter 23 is used to receive the blue light and green light reflected by the user's skin and to communicate with a host computer.

[0020] Specifically, in this embodiment, the traditional rare gas (xenon) lamp is replaced with blue LED 21 and green LED 22. Blue LED 21 and green LED 22 can be combinations of light-emitting diodes with peak wavelengths of 460nm and 550nm respectively, using alternating emission modes to distinguish the detection signal. The light signal converter 23 is a photoelectric signal processing module, which can use a circuit board integrating a photoelectric sensor and a Bluetooth chip to achieve reflected light intensity detection and wireless data transmission. It is understood that blue LED 21, green LED 22, and light signal converter 23 are all mounted on the circuit board of light signal converter 23. During jaundice monitoring, blue LED 21 and green LED 22 alternately irradiate blue and green light onto the user's skin. The blue and green light penetrate the skin, and utilizing the different absorption rates of blue and green light by bilirubin and hemoglobin within the skin tissue, respectively, the light signal converter 23 receives the reflected blue and green light from the skin tissue. This light signal is then converted into an electrical signal in real time and transmitted to the host computer (monitoring system). The host computer calculates the light density difference based on the received electrical signal. As the user receives blue light therapy, the absorption of blue light by bilirubin in the skin tissue gradually decreases, achieving continuous monitoring. In this embodiment, the blue light irradiation by blue LED 21 is only used to reflect the concentration of bilirubin in the skin tissue; its therapeutic effect is negligible. The method by which the host computer calculates the light density difference can be achieved using existing technologies.

[0021] Therefore, in this embodiment, the traditional rare gas (xenon) lamp is replaced by blue LED 21 and green LED 22 to achieve miniaturization of the monitoring light source. Since the attachment shell 1 is oriented towards the user, for example, it can be attached to the user's skin. During jaundice treatment, the attachment shell 1 remains attached to the user's skin surface, enabling 24-hour dynamic monitoring. This allows for continuous jaundice monitoring, improving the convenience and continuity of jaundice monitoring.

[0022] Optionally, combined Figure 1 As shown, the attachment shell 1 includes a first sidewall 11 and a perforation. The first sidewall 11 is used to attach to the user's skin, and the perforation is provided on the first sidewall 11. The blue LED 21, the green LED 22 and the light signal converter 23 are recessed into the perforation.

[0023] Specifically, a perforated hole is provided in the middle of the first sidewall 11. During installation, the outer casing 1 is fitted onto the outside of the monitoring structure 2, and the blue LED 21, green LED 22, and light signal converter 23 are located within the area enclosed by the perforated hole. Since the first sidewall 11 needs to be in contact with the user's skin, in order to facilitate the illumination of the skin by the blue LED 21 and green LED 22 and the reception of the reflected light by the light signal converter 23, the end face of the first sidewall 11 that is in contact with the user's skin is located between the user's skin and the blue LED 21, green LED 22, and light signal converter 23. That is, the blue LED 21, green LED 22, and light signal converter 23 are recessed into the perforated hole so that after the first sidewall 11 is in contact with the user's skin, there is a certain distance between the blue LED 21, green LED 22, and light signal converter 23 and the user's skin. For example, this distance can be 0-10 mm. The first sidewall 11 is attached to the user's skin, and the area surrounded by the perforated hole forms an independent light path illumination channel between the attached shell 1 and the user's skin.

[0024] Thus, by mounting the blue LED 21, green LED 22, and light signal converter 23 on a circuit board located within the cutouts in the first sidewall 11, the blue LED 21, green LED 22, and light signal converter 23 are fixed, ensuring accurate light path and consequently ensuring accurate signal transmission from the light signal converter 23 to the host computer. Since the first sidewall 11 of the attached housing 1 faces the user, for example, it can adhere to the user's skin. The area enclosed by the cutouts in the first sidewall 11 forms an independent light irradiation channel between the user's skin and the monitoring structure 2, preventing the light signal converter 23 from receiving light from the therapeutic blue light.

[0025] Optionally, combined Figures 1 to 3As shown, the jaundice monitoring device also includes a limiting seat 3. A limiting protrusion 31 is provided at one end of the limiting seat 3 facing the first side wall 11. The attached shell 1 is sleeved on the limiting seat 3, and the limiting protrusion 31 is engaged with the hollow hole. The limiting protrusion 31 includes a first through hole 311 and a second through hole 312. The blue LED 21 and the green LED 22 are located in the first through hole 311, and the light signal converter 23 is located in the second through hole 312.

[0026] Specifically, the outer shell 1 is a hollow shell structure. The limiting seat 3 is embedded inside the outer shell 1 through a sleeve connection. The limiting protrusion 31 and the hollow hole of the outer shell 1 form an interference fit, preventing relative displacement between the monitoring structure 2 and the outer shell 1. Consequently, the blue LED 21 and green LED 22 are confined within the first through hole 311, with their emitting surfaces facing the user's skin and maintaining a gap with the hole wall to prevent the light source from tilting and causing the light path to deviate. The light signal converter 23 is fixed within the second through hole 312 to prevent direct light from interfering with signal acquisition. The isolation design of the first through hole 311 and the second through hole 312 allows the light emission and reflection signal acquisition to form independent channels, reducing stray light interference.

[0027] Thus, by attaching the outer shell 1 to the limiting seat 3, with the limiting protrusion 31 engaging with the hollow hole, and by physically constraining the blue LED 21 and green LED 22 within the first through hole 311 and the light signal converter 23 within the second through hole 312, spatial stability of the light path transmitter and receiver is achieved. This eliminates displacement caused by vibration or shell deformation during long-term use of the monitoring structure, avoids detection errors caused by deviations in the illumination angles of the blue LED 21 and green LED 22, and prevents the light signal converter 23 from failing to collect reflected light signals due to positional shift. Furthermore, the regional distribution of the blue LED 21, green LED 22, and light signal converter 23 avoids direct illumination of the light signal converter 23 by the blue LED 21 and green LED 22, thus ensuring the continuity and accuracy of jaundice detection data.

[0028] Optionally, combined Figures 1 to 3 As shown, a limiting groove 32 is provided at one end of the limiting seat 3 away from the first side wall 11. The opening of the limiting groove 32 is away from the first side wall 11. The limiting groove 32 is connected to the first through hole 311 and the second through hole 312 respectively. The monitoring structure 2 is snapped into the limiting groove 32.

[0029] Specifically, the end of the limiting seat 3 that is away from the first side wall 11 is also the end of the limiting seat 3 that is away from the user's skin, the opening of the limiting groove 32 is away from the user's skin, and the limiting groove 32 is connected to the first through hole 311 and the second through hole 312 to form a continuous space.

[0030] Thus, a limiting groove 32 with a slot opening opposite to the first sidewall 11 is provided at one end of the limiting seat 3, and the monitoring structure 2 is snapped into the limiting groove 32. The limiting groove 32 is connected to the first through hole 311 and the second through hole 312 respectively. After the monitoring structure 2 (i.e. the circuit board of the monitoring structure 2) is snapped into the limiting groove 32, the limiting groove 32 forms a wrapping constraint on the side of the monitoring structure 2 through the groove wall, and together with the first through hole 311 and the second through hole 312, it limits the blue light LED 21, green light LED 22 and light signal converter 23, so that the distance between the blue light LED 21, green light LED 22 and light signal converter 23 and the skin contact surface is precisely limited. At the same time, the signal transmission line of the light signal converter 23 is led out through the independent channel formed by the limiting groove 32 and the second through hole 312, avoiding signal interference caused by line bending, and improving the continuity and reliability of jaundice detection data.

[0031] Optionally, the outer casing 1 is made of soft silicone material.

[0032] Specifically, soft silicone material can be made of liquid silicone with a Shore hardness range of 10A to 30A. The elastic properties of soft silicone allow it to deform under pressure to match the curvature of the skin surface, while returning to its original shape after the external force is removed.

[0033] Thus, by using a soft silicone material to attach the outer shell 1, when the soft silicone material attaches the outer shell 1 to the user's skin, the elastic deformation of the material itself eliminates the gap between the attaching shell 1 and the skin, forming a flexible contact interface without mechanical pressure. When the user's limbs move or body position changes, the deformation recovery ability of the shell can maintain a continuous fit with the skin, avoiding the relative position shift of the blue LED 21, green LED 2 and the skin due to the displacement of the shell.

[0034] Optionally, the number of blue LEDs 21 and green LEDs 22 are equal.

[0035] Specifically, when there is one blue LED21, there is also one green LED22; when there are two blue LEDs21, there are also two green LEDs22, and so on.

[0036] In this way, by ensuring that the number of blue LEDs 21 and green LEDs 22 are equal, the total number of photons emitted by the two light sources per unit time tends to be balanced, thus maintaining a stable intensity relationship between blue and green light in the reflected light signal. This improves the accuracy of bilirubin concentration calculation and ensures reliable jaundice monitoring during continuous blue light therapy.

[0037] Optionally, the outer casing 1 is configured as a cuboid shape, and the edges of the outer casing 1 are provided with rounded chamfers.

[0038] Specifically, the rounded chamfer refers to the smooth transition at each edge of the attached shell 1. This can be achieved by pre-setting the arc angle during mold processing. The rounded chamfer can eliminate the local pressure on the skin caused by right angles or sharp edges.

[0039] In this way, by setting the outer shell 1 to a cuboid shape and setting the edges of the outer shell 1 to have rounded chamfers, mechanical damage to the user's skin by the edges of the outer shell is avoided, ensuring that the device maintains stable contact with the skin during the monitoring process, thereby improving the accuracy of light signal acquisition and the safety of use.

[0040] Optionally, the housing 1 includes a wiring channel for connecting to a signal line, and the light signal converter 23 is wired to the host computer.

[0041] Specifically, the wiring channel can adopt a hollow tubular structure or a slotted structure to accommodate and fix the signal line, preventing the signal line from shifting or falling off during the device attachment process. Wired communication can be achieved using a USB interface, serial interface, or custom cable to establish a data transmission path between the light signal converter 23 and the host computer. This avoids electromagnetic interference that wireless communication may encounter in the blue light therapy environment, ensuring the continuity and reliability of signal transmission.

[0042] Thus, by utilizing the attached housing 1, which includes a wiring channel for connecting to the signal line, and the light signal converter 23 being wired to the host computer, the wiring channel ensures stable connection of the signal line in terms of physical structure, while the wired communication connection avoids the problem of inaccurate monitoring data caused by interference from wireless communication, thereby ensuring the reliability of signal transmission and improving the accuracy and real-time performance of jaundice monitoring.

[0043] Optionally, the sidewall of the attachment housing 1 opposite to the first sidewall 11 protrudes in a direction away from the first sidewall 11.

[0044] Specifically, the first sidewall 11 is the upper wall of the outer shell 1, and the sidewall opposite to the first sidewall 11 is the lower wall of the outer shell 1. The lower wall of the outer shell 1 protrudes in a direction away from the first sidewall 11.

[0045] Thus, by protruding the sidewall of the attached shell 1 opposite to the first sidewall 11 in a direction away from the first sidewall 11, the weight of the attached shell 1 can be increased within a certain range. After attachment, the friction between the attached shell 1 and the user's skin can be increased, thereby improving the anti-displacement capability and reducing signal acquisition errors caused by device offset.

[0046] Optionally, the outer surface of the limiting seat 3 is provided with anti-slip protrusions.

[0047] Specifically, the anti-slip protrusions can be hemispherical, pyramidal, or cylindrical protrusions. The anti-slip protrusions increase the roughness of the outer surface of the limiting seat 3, forming multiple points of contact between the outer surface of the limiting seat 3 and the inner wall of the attached shell 1, thereby generating frictional resistance.

[0048] Thus, by providing anti-slip protrusions on the outer surface of the limiting seat 3, when the limiting seat 3 is installed inside the attachment housing 1, the anti-slip protrusions form a localized squeezing contact with the inner wall of the attachment housing 1, which can limit the relative sliding between the limiting seat and the housing. This fixes the spatial position of the blue LED 21, green LED 22, and light signal converter 23, ensuring that the light path is aligned with the user's skin detection area, thereby ensuring that the light path of the monitoring structure is aligned with the skin area and avoiding detection signal distortion caused by displacement. Optionally, the outer surface of the attached housing 1 is provided with anti-slip texture.

[0049] Specifically, the anti-slip texture can be a cross-grid pattern, a wave pattern, or a dot matrix pattern, which increases the frictional resistance between the attached shell 1 and the external contact interface, preventing the attached shell 1 from sliding during operation or attachment.

[0050] Thus, by providing anti-slip textures on the outer surface of the attachment shell 1, the friction between the attachment shell 1 and the operator's hand and the user's skin can be enhanced, ensuring accurate positioning of the device during attachment and stability during monitoring, thereby improving the accuracy and reliability of jaundice detection data.

[0051] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
