Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a compact, pull-out resistant medical wire harness. Background Technology

[0002] In the modern medical field, the rapid development of technology has made medical equipment increasingly sophisticated and complex. The realization of its functions depends heavily on stable and efficient electrical connections. As a key medium for signal and power transmission inside medical equipment, the performance of medical wiring harnesses directly affects the reliability, safety, and clinical application effects of the equipment. By adopting a highly integrated design concept, multiple wires are precisely wrapped and the wiring structure is optimized so that they can be neatly arranged in a small space, avoiding tangling and mess, thereby achieving a miniaturized layout and providing strong support for the miniaturization process of medical equipment.

[0003] Traditional medical wiring harnesses can only meet the needs of connecting devices. However, in complex medical environments, the frequent movement and operation of equipment puts the wiring harnesses under great mechanical stress. Because these wiring harnesses lack tensile strength, even a slight drag or bump to the medical equipment can cause the wiring harness and connectors to fall off, making the medical equipment unable to operate and affecting the overall medical process and effect.

[0004] Therefore, there is an urgent need to provide a compact, pull-out resistant medical wire harness to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a compact, pull-out resistant medical wire harness.

[0006] To solve the above-mentioned technical problems, the present invention provides a compact anti-pull-out medical wire harness, comprising a wire tube, two insulating tubes fixedly connected inside the wire tube, wires installed inside the two insulating tubes, mounting blocks fixedly connected to both ends of the wire tube, connectors installed inside the two mounting blocks, metal sleeves installed at the inner ends of the two connectors, and anti-detachment mechanisms provided on the outer wall of the wire tube near both ends.

[0007] The present invention is further configured such that the conductor has a multi-layered sheathing structure.

[0008] Through the above technical solutions, the multi-layered wire structure can cancel out electromagnetic fields. This structure can effectively reduce electromagnetic radiation and received interference signals, thereby improving the accuracy and stability of signal transmission, reducing signal distortion and bit error rate, ensuring the normal operation of medical equipment and reliable data transmission. Compared with single wires, multi-layered wires are more flexible and have greater bendability, which can better adapt to the narrow space and complex wiring requirements inside medical equipment. They are easy to bend, twist and install inside the equipment, reducing the installation difficulty and risk of damage to the internal structure of the equipment caused by excessively stiff wires. At the same time, it also improves the user's ease of operation of the equipment.

[0009] The present invention is further configured such that one end of the connector is connected to two corresponding wires.

[0010] The above technical solution connects two corresponding wires at one end of the connector, which can ensure the continuity of the signal transmission path. Compared with connecting them to different locations, it can effectively reduce the space occupied by the connector. This compact connection method helps to realize the miniaturization design of the entire medical wiring harness, so that the wiring harness can better adapt to the narrow wiring channels and compact installation environment inside medical equipment.

[0011] The present invention is further configured such that the metal sleeve is fitted onto the connection between the connector and the two wires.

[0012] Through the above technical solution, the metal sleeve is fitted onto the connection between the connector and the two wires, which can effectively disperse the tensile force. The metal sleeve itself has high strength. For example, the tensile strength of the stainless steel sleeve is much higher than that of ordinary plastic connectors and wire sheaths, thereby greatly enhancing the tensile strength of the connection and reducing the risk of the connector separating from the wires.

[0013] The present invention is further configured such that: the anti-detachment mechanism includes a sliding groove and a plurality of limiting sliding grooves respectively opened on the outer wall of the conduit; a sliding ring is slidably connected to the outer wall of the sliding groove; a rotating ring is rotatably connected to the inner wall of the sliding ring; and a thread is opened on the outer wall of the rotating ring.

[0014] With the above technical solution, initially, the sliding ring is located in the sliding groove and can slide along the sliding groove. The rotating ring is rotatably connected to the sliding ring, which allows the rotating ring to rotate freely relative to the sliding ring. When the wire harness needs to be installed into the corresponding interface of the medical device, the connector is inserted into the device interface. At this time, the anti-detachment mechanism is inactive. After the connector is inserted into the device interface to the appropriate position, the operator can push the sliding ring to slide along the sliding groove, so that the anti-detachment mechanism is close to the locking structure of the device interface. Then, the rotating ring is rotated. Since the outer wall of the rotating ring is threaded, when it rotates, it will interact with the matching structure at the device interface. Through the engagement of the threads, the connection between the connector and the device interface is gradually tightened. This threaded connection method can provide a large axial tensile force, effectively preventing the connector from accidentally coming out of the device interface.

[0015] The present invention is further configured such that: a limiting strip corresponding to the limiting groove is fixedly connected to the outer wall of the sliding ring.

[0016] Through the above technical solution, during the operation of the anti-detachment mechanism, the cooperation between the limiting strip and the limiting groove can accurately control the movement direction of the sliding ring. When the sliding ring slides along the sliding groove, the limiting strip can only move within the limiting groove, which avoids the sliding ring from rotating in the circumferential direction or other unexpected displacements.

[0017] The present invention is further configured such that the inner wall of the rotating ring is fitted to the outer wall of the connector.

[0018] With the above technical solution, when the inner wall of the rotating ring is attached to the outer wall of the connector, a relatively sealed space can be formed between the two. In a medical environment, this helps to prevent external liquids and dust from entering the connection between the connector and the conduit. This tight fit can effectively block these substances and protect the internal electrical connection of the connector from damage, thereby reducing the risk of short circuits or other electrical faults.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. This utility model, through the design of an anti-detachment mechanism, allows the connection between the conduit and the device interface to be gradually tightened by simply rotating the rotating ring after the connector is connected to the corresponding device interface. This threaded connection method can provide a large axial tensile force, effectively preventing the conduit from accidentally coming out of the device interface when subjected to external force, thus providing a reliable anti-detachment guarantee for medical wire harnesses.

[0021] 2. This utility model installs a metal sleeve at the connection between the connector and the wire. The metal sleeve itself has high strength, and its tensile strength is much higher than that of ordinary plastic connectors and wire sheaths. This greatly enhances the tensile strength of the connection, reduces the risk of the connector separating from the wire, and also provides additional support and protection to prevent the connection from being damaged due to excessive bending or twisting.

[0029] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0030] Please see Figure 1 - Figure 6A compact, pull-out resistant medical wiring harness includes a conduit 1, with two insulating tubes 2 fixedly connected inside the conduit 1. Each of the two insulating tubes 2 contains a conductor 3, which has a multi-layered sheath structure. This multi-layered sheath structure allows electromagnetic fields to cancel each other out, effectively reducing electromagnetic radiation and received interference signals, thereby improving the accuracy and stability of signal transmission, reducing signal distortion and bit error rate, and ensuring the normal operation of medical equipment and reliable data transmission. Compared to a single conductor 3, the multi-layered sheath 3 is more flexible and has greater bendability, better adapting to the confined space and complex wiring requirements inside medical equipment. It facilitates bending, twisting, and installation inside the equipment, reducing installation difficulty and the risk of damage to the internal structure caused by excessively stiff conductors 3. It also improves the ease of operation for users. Mounting blocks 4 are fixedly connected to both ends of the conduit 1. The two mounting blocks 4 contain... Each connector 5 is equipped with a connector 5. One end of the connector 5 is connected to two corresponding wires 3. This connection ensures the continuity of the signal transmission path. Compared to connecting them to different locations, it effectively reduces the space occupied by the connector 5. This compact connection method helps to achieve the miniaturization of the entire medical wiring harness, allowing the harness to better adapt to the narrow wiring channels and compact installation environment inside medical equipment. The inner ends of both connectors 5 are equipped with metal sleeves 6. The metal sleeves 6 are fitted at the connection between the connector 5 and the two wires 3. This effectively disperses the tensile force. The metal sleeves 6 themselves have high strength. For example, the tensile strength of stainless steel sleeves is much higher than that of ordinary plastic connectors 5 and wires 3 sheaths, thereby greatly enhancing the tensile strength of the connection and reducing the risk of separation between the connector 5 and the wires 3.

[0031] like Figure 2 and Figure 3As shown, the anti-detachment mechanism 7 includes sliding grooves 701 and multiple limiting grooves 702 respectively formed on the outer wall of the conduit 1. A sliding ring 703 is slidably connected to the outer wall of the sliding groove 701, and a limiting strip corresponding to the limiting groove 702 is fixedly connected to the outer wall of the sliding ring 703. During the operation of the anti-detachment mechanism 7, the cooperation between the limiting strip and the limiting groove 702 can precisely control the movement direction of the sliding ring 703. When the sliding ring 703 slides along the sliding groove 701, the limiting strip can only move within the limiting groove 702, thus preventing slippage. If the moving ring 703 undergoes circumferential rotation or other unexpected displacement, the inner wall of the sliding ring 703 is rotatably connected to the rotating ring 704. The inner wall of the rotating ring 704 is in contact with the outer wall of the connector 5. When the inner wall of the rotating ring 704 is in contact with the outer wall of the connector 5, a relatively sealed space is formed between them. In a medical environment, this helps prevent external liquids and dust from entering the connection between the connector 5 and the conduit 1. This tight fit can effectively block these substances and protect the internal electrical connections of the connector 5 from damage. To reduce the risk of short circuits or other electrical faults, the outer wall of the rotating ring 704 is threaded with a thread 705. Initially, the sliding ring 703 is located in the sliding groove 701 and can slide along the sliding groove 701. The rotating ring 704 and the sliding ring 703 are rotatably connected, which allows the rotating ring 704 to rotate freely relative to the sliding ring 703. When the wire harness needs to be installed into the corresponding interface of the medical device, the connector 5 is inserted into the device interface. At this time, the anti-detachment mechanism 7 is in an inactive state. After the connector 5 is inserted into the device interface to the appropriate position, the operator can push the sliding ring 703 to slide along the sliding groove 701, so that the anti-detachment mechanism 7 is close to the locking structure of the device interface. Then, the rotating ring 704 is rotated. Since the outer wall of the rotating ring 704 is threaded with a thread 705, when it rotates, it will interact with the matching structure at the device interface. Through the meshing action of the thread 705, the connection between the connector 5 and the device interface is gradually tightened. This threaded connection method can provide a large axial tensile force, effectively preventing the connector 5 from accidentally coming out of the device interface.

[0032] When using this invention, if the wire harness needs to be installed into the corresponding interface of a medical device, the medical personnel insert the connector 5 into the corresponding interface of the device. After the connector 5 is inserted into the device interface to the appropriate position, the operator can push the sliding ring 703 to slide along the sliding groove 701, so that the anti-detachment mechanism 7 is close to the locking structure of the device interface. Then, rotate the rotating ring 704, and through the biting action of the thread 705, the connection between the connector 5 and the device interface is gradually tightened. Repeat the above actions to complete the connection and fixation of the other end of the wire harness. When it is necessary to disassemble the wire harness, simply rotate the sliding ring 703 in the opposite direction to make the sliding ring 703 fall off the medical device, and then pull out the connector 5 to complete the disassembly work. It is very quick and simple.
