Description

Technical Field

[0001] This utility model belongs to the field of medical equipment cable technology, specifically relating to a medical integrated magnetic ring and power cable assembly. Background Technology

[0002] Medical equipment is a core infrastructure ensuring diagnostic accuracy, treatment safety, and patient health. Its stable operation is directly related to the quality of medical services and patient safety. Common medical equipment includes patient monitors, ultrasound diagnostic instruments, and surgical robots. During operation, medical equipment typically needs to continuously acquire, process, and transmit sophisticated physiological signals or control critical actuators; therefore, it requires a high degree of stability in its operating environment.

[0003] However, medical settings present complex electromagnetic interference sources, primarily including internal and external interference. Internal interference originates from the electromagnetic radiation of the equipment's own circuit components, while external interference stems from signal radiation from other electronic devices within the hospital, harmonic disturbances in the power grid, and electromagnetic radiation generated by external communication base stations and radio frequency equipment. To ensure the reliable operation of medical equipment in this complex electromagnetic environment, its power cables, serving as the connection between the equipment and the external power supply system, need to possess a certain level of electromagnetic interference immunity. Currently, power cables mainly mitigate the impact of electromagnetic interference on signal accuracy through external filters.

[0004] However, external filters require additional wiring terminals to connect to the power interface and power lines of medical equipment, increasing the installation steps and wiring complexity, and also resulting in a large size. In the confined space of a hospital, external filters can easily become wiring obstacles, potentially introducing contact interference or safety hazards. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model provides a medical integrated magnetic ring and power cable assembly. By directly connecting the medical integrated magnetic ring to the power cable, an integrated design of the power cable assembly can be achieved, which helps to save installation and wiring space. The medical integrated magnetic ring is convenient to use and can more effectively suppress electromagnetic interference.

[0006] The technical effects to be achieved by this utility model are realized through the following technical aspects: In a first aspect, this utility model provides a medical integrated magnetic ring, comprising a first magnetic ring body, including a live wire winding and a neutral wire winding, wherein the first magnetic ring body has a live wire winding wound on the live wire winding for connection with a power cable, and a neutral wire winding wound on the neutral wire winding for connection with a power cable; a second magnetic ring body, disposed on one side of the first magnetic ring body, wherein a ground wire winding is wound on the second magnetic ring body for connection with a power cable; and a protective sleeve, which encloses the first magnetic ring body and the second magnetic ring body.

[0007] In some implementations, the live wire winding and the neutral wire winding are symmetrically distributed, and the number of turns of the live wire winding on the first magnetic ring body is equal to the number of turns of the neutral wire winding on the first magnetic ring body.

[0008] In some implementations, the live wire winding includes multiple first conductors wound in parallel on the live wire winding; the neutral wire winding includes multiple second conductors wound in parallel on the neutral wire winding.

[0009] In some implementations, the first conductor includes a live wire output terminal that passes through the body of the second magnetic ring, and the second conductor includes a neutral wire output terminal that passes through the body of the second magnetic ring.

[0010] In some implementations, the outer diameter of the first magnetic ring body is 20cm to 26cm, and the outer diameter of the second magnetic ring body is 20cm to 26cm.

[0011] In some implementations, the number of turns of the live wire winding is 8 to 10, and the number of turns of the neutral wire winding is 8 to 10.

[0012] In some implementations, the ground wire winding has 10 to 12 turns, and the ground wire winding includes a ground wire input terminal that passes through the first magnetic ring body.

[0013] In some implementations, an insulating film layer is provided on the outer side of the protective sleeve.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0024] Example 1: Please see Figure 1 and Figure 2 The medical integrated magnetic ring of this invention can be used in equipment cables, especially the power cables 4 of medical equipment, to effectively block electromagnetic interference and help ensure the stability of medical equipment.

[0025] This utility model discloses a medical integrated magnetic ring, comprising a first magnetic ring body 1, which includes a live wire winding 11 and a neutral wire winding 12. A live wire winding 13 is wound on the live wire winding 11 and connected to a power cable 4. A neutral wire winding 14 is wound on the neutral wire winding 12 and connected to the power cable 4. The medical integrated magnetic ring can be connected in series with the power cable 4 for easy storage, management, and portability. Specifically, the live wire winding 13 is evenly wound on the live wire winding 11 with several turns, and the neutral wire winding 14 is evenly wound on the neutral wire winding 12 with several turns.

[0026] A second magnetic ring body 2 is provided on one side of the first magnetic ring body 1. A ground wire winding 21 for connecting with the power cable 4 is wound on the second magnetic ring body 2. The ground wire winding 21 is evenly wound on the second magnetic ring body 2 and wound several turns.

[0027] The live wire winding 13 and the neutral wire winding 14 are wound around the first magnetic ring body 1, and the ground wire winding 21 is wound around the second magnetic ring body 2. The wound first magnetic ring body 1 and the second magnetic ring body 2 are then wrapped with a protective sleeve. Specifically, the protective sleeve is preferably, but not limited to, heat shrink tubing, which can play a role in fixing and insulating protection, ensuring the stability of the winding of the live wire winding 13, the neutral wire winding 14 and the ground wire winding 21.

[0028] In the integrated medical magnetic ring, the first magnetic ring body 1 and the second magnetic ring body 2 can perform layered suppression for different interference paths and types, which can significantly improve the overall electromagnetic interference resistance and optimize electromagnetic compatibility. Specifically, the live wire winding 13 and the neutral wire winding 14 are wound on the first magnetic ring body 1. When currents in opposite directions are applied to the live wire winding 13 and the neutral wire winding 14, they can cancel differential-mode flux to attenuate differential-mode interference. When the live wire winding 13 and the neutral wire winding 14 carry common-mode currents in the same direction, the first magnetic ring body 1 exhibits high impedance due to the common-mode current, thereby blocking common-mode interference in the circuit. The first magnetic ring body 1 suppresses interference within the circuit through the live wire winding 13 and the neutral wire winding 14.

[0029] Furthermore, when multiple medical devices share a grounding system, the ground wire winding 21 is wound separately on the second magnetic ring body 2, which can effectively attenuate the ground loop current, cut off the interference conduction path, and suppress high-frequency interference caused by external high-frequency electromagnetic radiation coupling into the ground wire. The first magnetic ring body 1 and the second magnetic ring body 2 suppress different types of interference, which helps to reduce the leakage magnetic field and external radiation of the integrated medical magnetic ring, and enhances the anti-electromagnetic interference capability. Medical devices can achieve stable operation and data security through the integrated medical magnetic ring.

[0030] Compared to traditional external filters, the integrated medical magnetic ring can be directly connected in series with the power cable 4, reducing its size and simplifying the installation steps and wiring complexity of medical equipment. This solves the problems caused by the dense wiring of external filters, which can lead to loose connections or contact interference due to accidental contact by doctors during operation.

[0031] Example 2: The difference between this embodiment and Embodiment 1 is that, please refer to... Figure 1 and Figure 2 In this embodiment, the live wire winding 11 and the neutral wire winding 12 are symmetrically distributed, with the axis of symmetry being the central axis of the first magnetic ring body 1. The live wire winding 13 and the neutral wire winding 14 are also symmetrically distributed. The number of turns of the live wire winding 13 on the first magnetic ring body 1 and the number of turns of the neutral wire winding 14 on the first magnetic ring body 1 are equal, which helps to suppress electromagnetic interference, reduce the occurrence of leakage flux, and comply with electromagnetic compatibility standards.

[0032] In a preferred embodiment, the live wire winding 13 includes multiple first conductors 131. Specifically, two first conductors 131 may be provided, and the two first conductors 131 are wound in parallel on the live wire segment. Each first conductor 131 includes a live wire input end 132 and a live wire output end 133. The live wire input end 132 is wound to the outside of the first magnetic ring body 1, while the live wire output end 133 passes through the second magnetic ring body 2. It is understood that this is not the only limitation on the number of first conductors 131, and those skilled in the art can adjust it according to their needs. Furthermore, the number of turns of the live wire winding 13 is 8 to 10 turns, such as 8 turns. The first conductors 131 are evenly wound on the live wire winding segment 11, and the spacing between adjacent coils of the first conductors 131 is equal.

[0033] Meanwhile, the neutral wire winding 14 includes multiple second conductors 141. Specifically, there may be two second conductors 141, which are wound in parallel on the neutral wire segment. Each second conductor 141 includes a neutral wire input end 142 and a neutral wire output end 143. The neutral wire input end 142 is wound to the outside of the first magnetic ring body 1, while the neutral wire output end 143 passes through the second magnetic ring body 2. Furthermore, the neutral wire winding 14 has 8 to 10 turns, which is equal to the number of turns in the live wire winding 13. The second conductors 141 are evenly wound on the live wire winding segment 11, and the spacing between adjacent coils of the second conductors 141 is equal.

[0034] In some specific embodiments, the ground winding 21 includes multiple third conductors 211. Specifically, two third conductors 211 may be provided, and the two third conductors 211 are wound in parallel on the second magnetic ring body 2. Each third conductor 211 includes a ground input terminal 212 and a ground output terminal 213. The ground input terminal 212 passes through the first magnetic ring body 1, and the ground output terminal 213 is wound to the outside of the second magnetic ring body 2. Specifically, the ground winding 21 has 10 to 12 turns. For example, 12 turns provide better electromagnetic interference resistance for the integrated medical magnetic ring.

[0035] The outer diameter of the first magnetic ring body 1 is 20cm~26cm, and the outer diameter of the second magnetic ring body 2 is 20cm~26cm. Specifically, the outer diameter of the first magnetic ring body 1 can be 26cm and the length is 24cm; the outer diameter of the second magnetic ring body 2 can be 26cm and the length is 24cm. The live wire winding 13 and the neutral wire winding 14 are wound on the first magnetic ring body 1, and the ground wire winding 21 is wound separately on the second magnetic ring body 2. This integrated medical magnetic ring suppresses electromagnetic interference to the greatest extent possible.

[0036] In some specific embodiments, an insulating film layer 3 is provided on the outer side of the protective sleeve. The insulating film layer 3 may include a PP inner film layer and a PV outer film layer. When the medical integrated magnetic ring is connected in series with the power cable 4, the insulating film layer 3 can be injection molded by injection molding process, which is easy to process.

[0037] Example 3: This embodiment, based on the above embodiments, provides a power cable assembly. Please refer to [link / reference]. Figure 3 .

[0038] A power cable assembly includes the aforementioned integrated medical magnetic ring and a power cable 4, wherein the power cable 4 includes an input section 41 and an output section 42, the integrated medical magnetic ring is disposed between the output section 42 and the input section 41, and the live wire winding 13, the neutral wire winding 14 and the ground wire winding 21 are electrically connected to the input section 41 and the output section 42, respectively.

[0039] Specifically, both the input section 41 and the output section 42 include three wire cores. The three wire cores of the input section 41 are respectively welded to the live wire input terminal 132, the neutral wire input terminal 142 and the ground wire input terminal 212, while the three wire cores of the output section 42 are respectively welded to the live wire output terminal 133, the neutral wire output terminal 143 and the ground wire output terminal 213. The welded joints can be insulated and protected by heat shrink tubing. The medical integrated magnetic ring and the power cable 4 are connected in series.

[0040] In some specific embodiments, the input section 41 is provided with a plug 5, which can be connected to a power source, and the output section 42 is provided with a socket 6, which can be connected to a medical device. Specifically, the integrated medical magnetic ring and the power cable 4 can be integrated through injection-molded insulating film layer 3, which provides a certain degree of protection for the first magnetic ring body 1 and the second magnetic ring body 2 while ensuring a small size.

[0041] The integrated medical magnetic ring and power cable 4 are convenient to use, eliminating the need for dense wiring. Furthermore, the power cable assembly meets medical-grade electromagnetic compatibility requirements, ensuring safe use, reducing the risk of leakage, and is resistant to disinfection. Traditional external filters can only suppress interference signals entering the device's power module. However, the short connecting cable between the external filter and the medical device can easily become a new interference coupling carrier, thus weakening the actual anti-interference effect. This utility model's power cable assembly, by connecting the integrated medical magnetic ring and power cable 4 in series, achieves layered interference suppression, resulting in a better overall filtering effect.
