Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a communication device and a medical device. Background Technology

[0002] With the increasing aging of the global population and growing health awareness, people's demand for convenient and efficient medical services is growing. Medical devices with Bluetooth communication capabilities can meet this demand, providing more intelligent and personalized solutions for medical services.

[0003] Many small communication medical devices have emerged, which offer convenience and real-time monitoring, data management and analysis, and telemedicine. The communication protocol is generally Bluetooth, which requires small medical devices to be equipped with Bluetooth antennas. However, Bluetooth signals are usually unstable. Summary of the Invention

[0004] This application aims to provide a communication device to improve the communication function of small medical devices and reduce signal instability problems.

[0005] In a first aspect, this application proposes a communication device, including a housing, a circuit board, and an antenna. The housing has a circular groove. The circuit board is disposed within the groove, and its surface facing the groove opening has a power supply pin, a ground pin, and a first suspended pin. The antenna is fitted against the inner wall of the groove, and is located on the side of the circuit board facing the groove opening. Along the circumference of the groove, the antenna includes a first end and a second end disposed opposite to each other. Viewed along the direction from the groove opening to the bottom of the groove, both the first end and the second end extend from the circuit board. The first end is connected to the first suspended pin, and the second end is connected to the power supply pin and the ground pin.

[0006] In the above solution, the circular groove allows for better placement of the circuit board and antenna, and the inner wall of the groove facilitates antenna fit. The presence of the first and second ends facilitates antenna manufacturing. This solution places the antenna on the side of the circuit board, keeping it away from the board and reducing interference from electrode components and metal parts on the board. This improves antenna efficiency, communication stability and reliability, and reduces signal instability. Furthermore, this solution is applicable to various small medical devices; only the overall antenna size and matching circuit need to be adjusted according to the actual design.

[0007] In some embodiments, the housing is made of plastic, ceramic, or rubber. These materials all have excellent insulating properties, providing protection while reducing signal interference.

[0008] In some embodiments, the antenna is made of stainless steel, copper, or nickel silver. Nickel silver is a copper-nickel alloy, and all three materials have good electrical conductivity.

[0009] In some embodiments, the communication device further includes a second suspended foot, disposed between the first suspended foot and the grounding foot along the direction from the first end to the second end. Providing a second suspended foot allows for adjustment of the antenna length as needed, thereby adjusting the antenna resonant frequency to meet different communication requirements.

[0010] In some embodiments, when viewed along the direction from the bottom of the groove to the opening, the height of the first end is less than that of the second end, which facilitates antenna production.

[0011] In some embodiments, the first end is welded to the first suspended foot, and the second end is welded to the feed foot and the ground foot. Welding not only facilitates installation, but the three welding points also improve the antenna's stability and contribute significantly to the overall airtightness.

[0012] In some embodiments, when viewed along the direction from the opening to the bottom of the groove, the power supply pin and the grounding pin are arranged parallel to each other. The parallel arrangement of the power supply pin and the grounding pin can form a stable electric and magnetic field distribution.

[0013] In some embodiments, a first distance exists between the main body of the antenna and the surface of the circuit board. Increasing the distance between the circuit board and the antenna reduces interference from the circuit board to the antenna.

[0014] In some embodiments, the communication device further includes a sealing ring. The housing has an annular groove surrounding the recess, and the sealing ring is disposed within the annular groove. The sealing ring provides waterproofing and improves the performance of the communication device.

[0015] Secondly, this application also proposes a medical device including a communication device as described in any of the embodiments of the first aspect above.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0029] In this application, the reference to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0030] In the description of the embodiments of this application, technical terms such as "first" and "second" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly defined.

[0031] The technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0032] With the increasing aging of the global population and growing health awareness, people's demand for convenient and efficient medical services is growing. Medical devices with Bluetooth communication capabilities can meet this demand, providing more intelligent and personalized solutions for medical services.

[0033] Many small communication medical devices have emerged, offering convenience and enabling real-time monitoring, data management and analysis, and telemedicine. These devices typically use Bluetooth communication, requiring them to be equipped with Bluetooth antennas. However, Bluetooth signals suffer from instability, data transmission delays, and interruptions.

[0034] To improve the performance of Bluetooth antennas and reduce signal instability, this application provides a communication device, please refer to... Figure 1 The communication device includes a housing 1, a circuit board 2, and an antenna 3. For details, please refer to... Figure 1 and Figure 2 The housing 1 has a circular groove 11. A circuit board 2 is disposed within the groove 11, and its surface facing the opening of the groove 11 has a feed pin 5, a ground pin 4, and a first suspended pin 6. An antenna 3 is fitted against the inner wall of the groove 11, and is located on the side of the circuit board 2 facing the opening. Along the circumference of the groove 11, the antenna 3 includes a first end 31 and a second end 32 positioned opposite each other. Viewed from the opening to the bottom of the groove 11, both the first end 31 and the second end 32 extend from the circuit board 2. The first end 31 is connected to the first suspended pin 6, and the second end 32 is connected to the feed pin 5 and the ground pin 4.

[0035] In the above scheme, the circular groove 11 allows for better placement of the circuit board 2 and the antenna 3, and the inner wall of the circular groove 11 facilitates the fit of the antenna 3. Furthermore, to ensure a better fit of the antenna 3 to the inner wall of the groove 11, surface mount technology can be used for the antenna 3. The presence of the first end 31 and the second end 32 facilitates the production of the antenna 3. This scheme places the antenna 3 on the side of the circuit board 2 rather than on top, thus keeping the antenna 3 away from the circuit board 2. This reduces interference from electrode components and metal parts on the circuit board 2, improves the efficiency of the antenna 3, enhances communication stability and reliability, reduces signal instability, and is applicable to various small medical devices; only the overall size of the antenna and the matching circuit need to be adjusted according to the actual design.

[0036] In some embodiments, the housing 1 is made of plastic, ceramic, or rubber. It is understood that all three materials can effectively protect the internal components and have good insulation properties. Among them, ceramic materials have a relatively stable dielectric constant, resulting in less signal absorption and scattering, providing a better transmission environment and thus improving signal stability.

[0037] In some embodiments, the antenna 3 is made of stainless steel, copper, or nickel silver. Nickel silver is a copper-nickel alloy, and all three materials have good electrical conductivity. Stainless steel has good strength and hardness, making the antenna 3 less prone to deformation or damage. Copper has good ductility and flexibility, making it easy to process into various shapes and sizes. Nickel silver has a smooth surface, which helps reduce signal scattering and reflection during transmission, thus improving signal transmission quality.

[0038] In some embodiments, please refer to Figure 1 The communication device also includes a second suspended foot 7, which is disposed between the first suspended foot 6 and the grounding foot 4 along the direction from the first end 31 to the second end 32. The second suspended foot 7 allows the communication device to adjust the length of the antenna 3, thereby adjusting the antenna resonant frequency to meet different communication requirements.

[0039] In some embodiments, when viewed along the direction from the bottom to the opening of the groove 11, the height of the first end 31 is less than that of the second end 32. By setting a height difference, the antenna 3 can be manufactured more efficiently, thus improving production efficiency.

[0040] In some embodiments, the first end 31 is welded to the first suspended foot 6, and the second end 32 is welded to the feed foot 5 and the ground foot 4. Welding ensures a stable connection between the antenna 3 and the feed foot 5 and ground foot 4, providing stability for the antenna 3. Welding not only facilitates installation, but the three solder points also improve the antenna's stability and contribute significantly to the overall airtightness. It is understood that tin soldering is commonly used in electronic products, as tin has good conductivity, allowing current to flow smoothly through the solder joints and reducing signal loss and interference during transmission.

[0041] In some embodiments, when viewed along the direction from the opening to the bottom of the groove 11, the power supply pin 5 and the grounding pin 4 are arranged in parallel. The parallel arrangement of the power supply pin 5 and the grounding pin 4 can form a more stable and uniform electric and magnetic field distribution, which reduces interference to the signal during transmission and reduces signal reflection, scattering and loss.

[0042] In some embodiments, the main body of the antenna 3 has a first distance (not shown in the figure) between it and the surface of the circuit board 2. By setting the first distance, the antenna 3 can be further moved away from the circuit board 2, reducing the interference of the circuit board 2 on the antenna 3 and providing stability for signal transmission.

[0043] In some embodiments, the communication device further includes a sealing ring (not shown). The housing 1 has an annular groove 12 surrounding the recess 11, and the sealing ring is disposed within the annular groove 12. By providing the sealing ring, waterproofing can be achieved, improving the waterproof performance of the communication device.

[0044] This application also provides simulation results for some of the above embodiments; please refer to them. Figure 4 , Figure 4 The antenna efficiency is shown. In small communication devices, the antenna efficiency is typically around 20%, while the figure shows that the peak efficiency of this antenna is around 35% in the 2.4GHz to 2.48GHz range, exhibiting good antenna efficiency. Secondly, this application also proposes a medical device including a communication apparatus as described in any embodiment of the first aspect above.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them; under the concept of this application, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of this application as described above, which are not provided in detail for the sake of brevity; although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
