[0030] The technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The structures involved in the present invention are not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0031] Example:
[0032] See also Figure 1-5 The present invention provides a technical solution: a universal connector device applicable to various medical devices, comprising an outer shell and an inner shell, wherein the outer shell wraps the inner shell, and the inner shell is divided into a top shell 1 and a bottom shell 2, wherein a fixed connector 3 is clamped between the top shell 1 and the bottom shell 2;
[0033] The shell is made of soft rubber material, providing excellent shock resistance, drop resistance and sealing performance. Its outer layer is made of medical-grade silicone rubber (compliant with ISO 10993 biocompatibility standards) with a hardness of 50±5 Shore A, which is both flexible and tear-resistant.
[0034] The inner layer is embedded with conductive rubber layer (surface resistance <10 3 Ω), achieving electrostatic shielding function to prevent electromagnetic interference (EMI) from affecting sensitive medical equipment.
[0035] It is divided into two parts, the top cover 4 and the bottom cover 5, which are seamlessly connected through a precise snap-fit structure. The surface of the shell is designed with anti-slip patterns to facilitate medical staff to hold during operation. It has IP67-level waterproof and dustproof performance and can withstand liquid splashes in medical environments.
[0036] The inner shell is made of high-strength polycarbonate (PC) + 30% glass fiber reinforced with a bending strength of ≥120MPa. It is divided into two parts, the top shell 1 and the bottom shell 2, forming a precisely matched clamping structure. A special fixing seat and positioning structure are designed inside to ensure the precise alignment of each component, and an interlocking design of the arc plate 22 and the concave groove 12 is adopted at the rear end to enhance structural stability.
[0037] In the accompanying drawings, connector 3 is a connector 3 model of a power line, but the actual connector 3 can also be a connector 3 of a signal line, so it supports multiple interface types (power line / signal line) and adopts a modular design. The rear end of connector 3 is connected to the wiring tube 8 through a high-conductivity copper alloy limiting plate 7, and the connector 31 and the conductive column 6 are gold-plated to ensure low contact resistance and oxidation resistance.
[0038] The rear end of the connector 3 is connected to a wiring tube 8 through a limiting plate 7. The wiring tube 8 is provided with an anti-retreat mechanism. The wire body 91 of the medical device wire 9 penetrates into the wiring tube 8 through the wire seat 23, and the wire body 91 penetrates into the wire tube 9 and is fixed by the anti-retreat mechanism. The wire body 91 is prevented from retreating by the anti-retreat mechanism. The wire body 91 and the connector 3 are electrically connected.
[0039] The anti-backward mechanism includes a limiting gear 83 and a limiting portion 82. The outer wall of the wire tube 9 is symmetrically provided with a groove body for accommodating the limiting gear 83. The tooth pattern of the limiting gear 83 is in the forward direction. A limiting portion 82 is provided on the side wall of the groove body for accommodating the limiting gear 83 to prevent the limiting gear 83 from reversing. The limiting portion 82 adopts an elastic paddle structure. When the limiting gear 83 rotates forward, the paddle structure fluctuates along the tooth pattern of the forward rotating limiting gear 83. When the limiting gear 83 reverses, the paddle structure is stuck in the tooth pattern of the limiting gear, resulting in the limiting gear 83 being unable to reverse.
[0040] Among them, the limiting gear 83 can be made of precision metal gears with optimized tooth angles, and the elastic paddles of the limiting part 82 can be made of special stainless steel with a service life of over one million times, thereby forming a double anti-retreat mechanism, mechanical blocking + friction braking, to ensure that the wire body 91 is absolutely fixed.
[0041] The anti-retreat mechanism can specifically adopt a 17-tooth limit gear (module 0.8) with a beryllium bronze elastic paddle, with a forward resistance of less than 0.1N·m and a reverse locking torque of more than 2N·m.
[0042] A conductive sleeve 81 made of conductive material is embedded in the wire 9 tube near the joint 3 , and the wire body 91 of the wire 9 is in contact with the conductive sleeve 81 .
[0043] The wire body 91 of the wire 9 is nested in the wire holder 23 , and the connection between the wire 9 and the wire holder 23 is wrapped with an insulating tape 92 .
[0044] The wire body 91 of the wire 9 is extended into the wire 9 tube corresponding to the wire holder 23, and the wire body 91 passes through the limit gear 83 to make it rotate forward, and until the wire body 91 contacts the conductive sleeve 81 of the wiring tube 8 and the conductive seat 71, thereby achieving circuit connection, and the wire body 91 of the wire 9 is pulled back. When the limit gear 83 is reversed, it is stuck by the limit part 82 to prevent it from reversing and forming a fixed position, and then the connection between the wire 9 and the wire holder 23 is wrapped with insulating tape 92.
[0045] The outer shell is divided into a top cover 4 and a bottom cover 5 . The top cover 4 is engaged with the top shell 1 , and the bottom cover 5 is engaged with the bottom shell 2 .
[0046] The bottom shell 2 is provided with lower fixing seats 21 on the left and right sides, and a semicircular arc-shaped plate 22 is provided on the rear end of the bottom shell 2. The top shell 1 is provided with upper fixing seats 11 on the left and right sides. The positions of the upper fixing seats 11 correspond to the positions of the lower fixing seats 21. The rear end of the top shell 1 is provided with a concave groove 12. The arc-shaped plate 22 of the bottom shell 2 is engaged with the concave groove 12 of the top shell 1.
[0047] Engage the curved plate 22 of the bottom shell 2 with the concave groove 12 of the top shell 1, so that the upper fixing seat 11 and the lower fixing seat 21 correspond to each other, then engage the top cover 4 with the top shell 1, and then engage the bottom cover 5 with the bottom shell 2, and fix them with screws that pass through the top cover 4, top shell 1, bottom shell 2 and bottom cover 5 in sequence.
[0048] The rear end of the connector 3 is connected to a socket 31 , and the rear end of the socket 31 is connected to a limiting plate 7 via a conductive column 6 .
[0049] The limiting plate 7 is nested with a conductive seat 71 , one side of the conductive seat 71 is nested corresponding to the conductive column 6 , and the other side of the conductive seat 71 is in contact with the wire body 91 of the wire 9 .
[0050] In another embodiment:
[0051] Increased safety protection design, the device has a built-in overcurrent protection circuit and can be integrated with a micro fuse;
[0052] Added anti-misinsertion design: different interface types use different key structures;
[0053] Add EMI shielding layer: reduce the impact of electromagnetic interference on sensitive medical equipment;
[0054] Increased tensile strength design: the wire body 91 can withstand a tensile force of more than 50N after being fixed.
[0055] A universal connector 3 suitable for a variety of medical devices.
[0056] Snap the connector 3 and the socket 31 together with the bottom shell 2, then place the conductive column 6 between the socket 31 and the limiting plate 7, snap the two conductive seats 71 together with the limiting plate 7, and then snap the two sets of wiring tubes 8 together with the two conductive seats 71;
[0057] Engage the curved plate 22 of the bottom shell 2 with the concave groove 12 of the top shell 1, so that the upper fixing seat 11 and the lower fixing seat 21 correspond to each other, then engage the top cover 4 with the top shell 1, and then engage the bottom cover 5 with the bottom shell 2, and fix them with screws that pass through the top cover 4, top shell 1, bottom shell 2 and bottom cover 5 in sequence.
[0058] The above is the assembly method of the connector 3 device. The following is how to install the connector 3:
[0059] Remove the insulation layer of the lead 9 of the medical device and nest the wire body 91 of the wire 9 in the wire seat 23;
[0060] The wire body 91 is continuously inserted into the wiring tube 8, and the wire body 91 passes through the limit gear 83 to rotate forward until the wire body 91 contacts the conductive sleeve 81 and the conductive seat 71 of the wiring tube 8, thereby achieving circuit connection;
[0061] Pull the wire 9 body 91 back, and when the limit gear 83 is reversed, it is stuck by the limit portion 82 to prevent it from reversing and forming a fixed position. Then, the connection between the wire 9 and the wire seat 23 is wrapped with an insulating tape 92.
[0062] This installation method only requires a pair of scissors to remove the insulation layer on the outside of the wire 9, so that the wire body 91 of the wire 9 is exposed. It can be completed without any other tools. The insulating tape 92 can be added by electricians later, and medical staff do not need to complete the sealing at the time.
[0063] During the installation process: it is best to manually extend the wire body 91 into the wiring tube 8 continuously. The wire body 91 passes through the limit gear 83 to make it rotate forward, advance to about 1 / 3 of the stroke, then rotate and advance clockwise 15° alternately, and finally push it in slowly. The limit gear 83 forms scratches on the rotational contact of the outside of the wire body 91, further increasing the resistance when the wire body 91 retreats.
