Description

Technical Field

[0001] This utility model belongs to the field of flexible wire technology, and in particular relates to a flexible wire. Background Technology

[0002] With the development of modern medical technology, the application of flexible wires in medical devices has become increasingly important. Flexible wires not only need to possess high flexibility to adapt to the curves of the human body and complex environments, but also need to have good electrical properties and biocompatibility to ensure safety and reliability during long-term use. Currently, flexible wires are widely used in wearable medical devices, implantable medical devices, and various medical sensors, which typically require wires with extremely high flexibility, durability, and stability.

[0003] In some wearable medical devices, such as continuous glucose monitors, electrocardiogram monitors, pulse oximeters, blood pressure monitors, hearing aids, drug delivery systems, and defibrillators, wires that are adapted to the human body are often required to connect the device to the human body.

[0004] For example, Chinese patent CN219959516U discloses a connecting cable for medical devices, comprising wires, several of which form a group, with connecting strips between the wires, connectors at both ends of the wires, reinforcing strips between the connectors, and several elastic strips connecting the reinforcing strips and connecting strips. The elastic strips at both ends are close to the connectors, and magnetic rings are fitted at both ends of the wires, located between the connectors and the elastic strips. This invention increases the strength of the wire by connecting reinforcing strips between the connectors and protects both ends of the wire. The elastic strips between the reinforcing strips and connecting strips limit the proximity of the magnetic rings to the connectors, ensuring that the magnetic rings are installed as close as possible to the power source, i.e., close to the cable inlet and outlet.

[0005] This patented cable has several drawbacks in use, including: firstly, the cable's length is not easily adjustable to meet different user needs, resulting in low overall adjustability; secondly, it lacks robust anti-interference measures, such as improved anti-interference capabilities, which are crucial for data transmission in medical devices; and thirdly, its heat dissipation is poor, as the cable generates heat during use and cannot effectively dissipate this heat, leading to a rapid decrease in its lifespan after prolonged use. Therefore, we propose a flexible cable. Utility Model Content

[0006] The purpose of this invention is to provide a flexible wire to solve the problems mentioned in the background art.

[0007] In view of this, the present invention provides a flexible wire, comprising:

[0008] The main body of the wire has a spiral structure. Connectors are provided at both ends of the main body of the wire. A circular hole is opened at the center of the connector. A retaining ring is inserted into the circular hole. The two ends of the main body of the wire are respectively inserted into two retaining rings. Multiple heat dissipation grooves are opened on the circumferential sidewall of the circular hole at equal intervals, and the multiple heat dissipation grooves are all connected to the circular hole.

[0009] Two sets of fixing components are arranged symmetrically and located directly above and below the connector, respectively, and are used to compress the retaining ring so that the retaining ring clamps and fixes the end of the wire body.

[0010] Two sets of anti-interference components are arranged symmetrically and located on the left and right sides of the connector, respectively, and are used to reduce the adverse effects of electromagnetic interference on the equipment.

[0011] In the above technical solution, the fixing component further includes:

[0012] An embedding groove is formed on the inner circumference of a circular hole. A C-shaped extrusion block is provided in the embedding groove. A threaded hole communicating with the embedding groove is formed on the side wall of the connector. A threaded knob is threadedly connected in the threaded hole, and one end of the threaded knob extends into the embedding groove and rotates with the extrusion block.

[0013] In the above technical solution, the outer end of the screw knob is provided with anti-slip texture, and the inner side of the extrusion block is in contact with the outer circumferential wall of the retaining ring.

[0014] In the above technical solution, the anti-interference component further includes:

[0015] The side is fixedly installed on the side wall of the connector, and a placement groove is provided on the side, in which a magnetic ring is installed.

[0016] In the above technical solution, the connector has symmetrically provided fixing holes on its sidewall.

[0017] Furthermore, in the above technical solution, the retaining ring is elastic.

[0018] In the above technical solution, the wire body further includes:

[0019] Multiple signal lines are distributed at equal intervals around the circumference. Several evenly distributed hemp ropes are filled between the multiple signal lines. A shielding layer is provided on the outside of the signal lines and hemp ropes. A filling layer is provided inside the shielding layer and around the multiple signal lines and hemp ropes. From the inside to the outside, the shielding layer is provided with an insulation layer, an anti-interference layer, a non-woven fabric covering layer, an aluminum foil layer, a braided layer, an inner protective layer, and an outer sheath layer.

[0020] The beneficial effects of this utility model are:

[0021] 1. This flexible wire improves the elasticity and adjustability of the wire body by setting the main body of the wire into a spiral structure, thereby enhancing the user experience.

[0022] 2. This flexible cable, by adding an anti-interference component to the head end of the cable body, uses a magnetic ring in the anti-interference component to absorb and suppress interference signals from interference sources, which can minimize the impact of electromagnetic interference on the equipment, ensure that medical data is not corrupted during transmission, and improve data accuracy; by setting a multi-layer protective structure and anti-interference structure on the cable body, the anti-interference capability of the cable body is further enhanced.

[0023] 3. This flexible wire has multiple equally spaced, annular heat dissipation grooves at the head end of the wire body. These grooves dissipate heat from the head end, a region prone to heat generation. The heat can be quickly diffused into the air through the grooves, ensuring the stability of the wire body during use and extending its service life. Attached Figure Description

[0035] Example 1:

[0036] Please see Figure 1 - Figure 4 As shown, this embodiment provides a flexible wire, including:

[0037] The main body of the wire is 1, which has a spiral structure. Connectors 2 are provided at both ends of the main body of the wire. A circular hole 3 is opened at the center of the connector 2. A retaining ring 4 is inserted into the circular hole 3. The two ends of the main body of the wire are respectively inserted into two retaining rings 4. Multiple heat dissipation grooves 9 are provided on the circumferential sidewall of the circular hole 3, and the multiple heat dissipation grooves 9 are all connected to the circular hole 3.

[0038] Two sets of fixing components are symmetrically arranged and located directly above and below the connector 2, respectively, and are used to compress the retaining ring 4 so that the retaining ring 4 clamps and fixes the end of the wire body 1.

[0039] Two sets of anti-interference components are arranged symmetrically and located on the left and right sides of connector 2, respectively, and are used to reduce the adverse effects of electromagnetic interference on the equipment.

[0040] In this embodiment, the fixing component includes:

[0041] The embedding groove 5 is opened on the inner circumference of the circular hole 3. The embedding groove 5 is provided with a C-shaped extrusion block 6. The side wall of the connector 2 is provided with a threaded hole 7 that communicates with the embedding groove 5. A threaded knob 8 is threadedly connected in the threaded hole 7, and one end of the threaded knob 8 extends into the embedding groove 5 and rotates with the extrusion block 6.

[0042] In this embodiment, the anti-interference component includes:

[0043] Side 11 is fixedly installed on the side wall of connector 2. A placement groove 12 is provided on side 11, and a magnetic ring 13 is installed in the placement groove 12.

[0044] In use, the head end of the wire body 1 can be passed through the retaining ring 4. Then, the threaded knobs 8 in the two fixing components on the upper and lower sides of the connector 2 are rotated to tighten the threaded knobs 8 inward. When the threaded knobs 8 are rotated inward, they push the pressing block 6 closer to the retaining ring 4, thereby creating a pressing sensation on the retaining ring 4. After the retaining ring 4 is pressed, it transmits the pressure to the wire body 1, thereby achieving the clamping and fixing of the wire body 1.

[0045] By adding an anti-interference component to the head end of the main body 1 of the wire, the magnetic ring 13 in the anti-interference component absorbs and suppresses the interference signal of the interference source, which can minimize the impact of electromagnetic interference on the equipment, ensure that medical data will not be corrupted during transmission, and improve the accuracy of the data.

[0046] By setting multiple equally spaced, annular heat dissipation grooves 9 at the head end of the wire body 1, heat dissipation grooves 9 are used to dissipate heat at the head end of the wire body 1, where heat is prone to be generated. Heat can be quickly diffused into the air through multiple heat dissipation grooves 9, ensuring the stability of the wire body 1 during use and also improving the service life of the wire body 1.

[0059] The cable body 1 is equipped with hemp rope 15 to enhance its structural strength and tensile strength. A shielding layer 17 effectively shields the electromagnetic signals generated by the multiple signal lines 14 inside the cable body 1 during operation. An insulation layer 18 enhances the insulation of the cable body 1, preventing leakage of the multiple signal lines 14 during operation. The anti-interference layer 19 is composed of a transparent absorbing layer, a nano-superconducting graphite absorbing layer, and a reflection and transmission layer, further enhancing the anti-interference and shielding performance of the cable body 1 and ensuring the stability of the signal lines 14 during data transmission. An aluminum foil layer 21 and a braided layer 22 are placed outside the signal lines 14, providing dual electromagnetic shielding to prevent external electromagnetic interference from affecting signal transmission. The cable body 1 exhibits extremely strong anti-interference performance, providing excellent protection for the transmission of medical data. The inner protective layer 23 and the outer sheath layer 24 are made of polyvinyl chloride and cross-linked polyethylene, respectively, providing excellent protection for the interior of the cable body 1.
