Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of defibrillators, and more particularly to an anti-reuse structure of a disposable electrode sheet of a defibrillator. Background Art
[0002] In medical emergency scenarios, defibrillators are critical devices for saving the lives of cardiac arrest patients. Defibrillator electrodes, as the crucial components that connect the defibrillator to the patient's body and enable effective current conduction, are crucial for their safety and reliability. Previously, researchers have been dedicated to developing anti-reuse structures to address the numerous risks associated with reusing disposable electrodes, such as increased risk of cross-infection, reduced defibrillation effectiveness, and even life-threatening consequences.
[0003] Chinese patent publication number CN116832331B discloses an anti-reuse structure for defibrillator electrodes. Through a unique design of an electrode plug and an electrode socket, it aims to effectively prevent the electrodes from being reused physically without affecting their normal use.
[0004] However, this structure has exposed a series of problems in actual application. On the one hand, due to its disposable design, during the defibrillation operation, when medical staff take the electrode and stick it to the patient's body, it is easy to pull the wire due to inadvertent movements, which will cause the electrode plug and the electrode socket to detach. Since the electrode is made of disposable material, it cannot be used again once it is detached. This is very likely to cause the embarrassing situation that the electrode is scrapped before the patient is treated, which not only causes a waste of resources, but also may delay the patient's rescue time; on the other hand, the structure has obvious deficiencies in the stability of preventing the reuse function. The diameter of the electrode plug is much smaller than the inner side of the blocking shrapnel, and the blocking shrapnel is made of elastic material. When it is misoperated, if the electrode plug is forced toward the electrode, the electrode will be damaged. When the electrode of the electrode socket is inserted into the inside, the center column strongly squeezes the blocking spring, and the blocking spring will be deformed and then sleeved on the outside of the electrode of the electrode socket, so that the electrode plug electrode can still be inserted into the inside of the electrode socket electrode, and the disposable function cannot be stably realized. Even if the operation is standardized, if the user plugs the electrode plug and the electrode socket with force, the electrode plug and the electrode socket will still be closed. In addition, the structure lacks an anti-fall-off design. During actual use, the connection between the electrode plug and the electrode socket is prone to accidental separation due to various external force factors, further affecting the stability and reliability of the use of the defibrillator electrode. These problems seriously restrict the effective application of the anti-reuse structure in actual medical scenarios, and therefore need to be improved and designed. Summary of the Invention

The top of the limiting components is connected to the bottom of the electrode patch socket. The limiting components are arranged on the outside of the electrode insertion rod and the movable component.
[0009] Optionally, the limiting component includes a concave frame. The concave frames are fixedly installed in an equidistant annular arrangement at the bottom of the electrode patch plug. An elastic insulating limiting rod is hinged inside the concave frame. A linkage rod is fixedly installed inside the elastic insulating limiting rod. The elastic insulating limiting rod is shaped like a '丿' character.
[0010] Optionally, the movable component includes a limiting rubber ring and a movable sleeve. The movable sleeve is slidably connected to the outer surface of the electrode insertion rod. The limiting rubber ring is fixedly installed at the upper end of the electrode insertion rod. An annular card slot is opened inside the movable sleeve. The shape of the annular card slot is adapted to the shape of the limiting rubber ring.
[0011] Optionally, a conical guiding groove is opened at the top of the movable sleeve. The bottom of the limiting rubber ring is conical.
[0012] Optionally, an anti-detachment ring is fixedly connected to the lower end of the outer surface of the electrode insertion rod. The diameter range of the anti-detachment ring is 0.2 CM - 0.5 CM. The inner diameter range of the electrode sleeve is 0.21 CM - 0.51 CM.
[0013] Optionally, a conical inclined surface is opened at the top of the movable sleeve. The outside of the conical inclined surface is in close connection with the bottom of the linkage rod.
[0014] Optionally, the anti-falling mechanism includes an annular groove and a top card group, the top card group is fixedly connected to the lower end of the outer surface of the outer sleeve, the annular groove is opened at the top of the base and is located on the outside of the electrode sheet socket, the inside of the annular groove is fixedly connected to a torsion spring, and the top of the torsion spring is fixedly connected to the bottom card group.
[0015] Optionally, the top card group includes a fixing ring, the outer side of the fixing ring is fixedly installed with protrusions at equal intervals, the middle part of the protrusion is provided with a through groove, the bottom of the protrusion is fixedly connected with an arc-shaped limit pin, and the end of the arc-shaped limit pin is inserted into the inner side of the bottom card group.
[0016] Optionally, the bottom card group includes a slip ring, which is rotatably connected to the top of the annular groove, the bottom of the slip ring is fixedly connected to the top of the torsion spring, and the outer side of the slip ring is fixedly connected with an arc-shaped limit sleeve arranged in a ring at equal intervals, and the end of the arc-shaped limit pin is inserted into the interior of the arc-shaped limit sleeve, and the arc-shaped limit sleeve and the arc-shaped limit pin are both arranged concentrically with the torsion spring.
[0017] Optionally, the bottom card group also includes a support rod and an adjustment handwheel.

[0018] Compared with the prior art, the technical solution provided by the present invention has at least the following beneficial effects:
[0019] The electrode plug is then pulled out of the socket, and the movable sleeve is fixed on the insulating limit rod, so that the elastic insulating limit rod is closed and tightly covers the electrode plug rod to prevent it from being plugged in again, thus preventing violent plugging and reuse.
[0020] The anti-falling mechanism of this device greatly improves the stability of use. When plugging the electrode plug and the electrode socket, turning the adjusting hand wheel drives the arc-shaped limit sleeve to rotate, squeezing the slip ring and compressing the torsion spring, so that the arc-shaped limit sleeve and the arc-shaped limit pin are separated and misaligned, which is convenient for the smooth plugging of the electrode plug and the electrode socket. The one-time locking mechanism is triggered, and the support rod is inserted into the through groove to prevent the electrode plug and the electrode socket from rotating, completing the initial limit. After the installation is completed, the adjusting hand wheel is loosened, and the torsion spring resets and drives the slip ring back to its position. The arc-shaped limit sleeve is arranged on the outside of the arc-shaped limit pin, which firmly fixes the electrode plug in the electrode socket to avoid accidental falling off. When dismantling, twist the adjusting hand wheel to rotate the slip ring, and the arc-shaped limit sleeve is separated from the arc-shaped limit pin, so that the electrode plug and the electrode socket can be separated, which has both stability and convenience.

[0048] like Figures 1 to 10As shown, an embodiment of the present invention provides a defibrillator disposable electrode anti-reuse structure, including a base 1 and an electrode plug 2, wherein an electrode socket 3 is fixedly installed on the top of the base 1, an electrode sleeve 4 is fixedly installed inside the electrode socket 3, the electrode plug 2 is arranged directly above the electrode socket 3, an outer sleeve 5 is fixedly installed on the bottom of the electrode plug 2, the outer sleeve 5 is covered on the outside of the electrode socket 3, a disposable locking mechanism 6 is movably installed inside the outer sleeve 5, an anti-falling mechanism 7 is fixedly installed on the outside of the electrode socket 3, the bottom of the anti-falling mechanism 7 is connected to the top of the base 1, and the electrode socket 3 and the electrode plug 2 are clamped together by the anti-falling mechanism 7.
[0049] like Figure 5-Figure 9 As shown, the disposable locking mechanism 6 includes a movable component 61, an electrode rod 62 and a limit component 63. The electrode rod 62 is fixedly installed at the bottom of the electrode plug 2 and is located inside the outer sleeve 5. The movable component 61 is arranged on the outer surface of the electrode rod 62. The limit components 63 are arranged in a ring shape at equal intervals and are arranged at the upper end of the outer sleeve 5. The top of the limit component 63 is connected to the bottom of the electrode socket 3. The limit component 63 is arranged on the outside of the electrode rod 62 and the movable component 61. When initially installed during use, the electrode plug 2 is located directly above the electrode socket 3, and the outer sleeve 5 covers the electrode socket 3.
[0050] like Figure 5 and Figure 6 As shown, during installation, the electrode plug 2 is placed on top of the electrode socket 3. In the disposable locking mechanism 6, the movable component 61, due to the action of gravity, squeezes the elastic insulating limit rod 632 in the limit component 63 to expand it, and the electrode plug 2 is plugged into the electrode socket 3. The electrode sleeve 4 squeezes the movable component 61 upward, and the movable component 61 is clamped to the upper end of the electrode plug rod 62 through a specific structure to achieve power conduction. At the same time, the movable component 61 squeezes the linkage rod 633, causing the elastic insulating limit rod 632 to rotate inward and fit the electrode sleeve 4. After use, the electrode plug 2 and the electrode socket 3 are pulled out, and the movable component 61 is fixed on the insulating limit rod, causing the elastic insulating limit rod 632 to close and tightly cover the electrode plug rod 62, preventing it from being plugged in again, thereby preventing reuse. In addition, the anti-dropout mechanism 7 on the outside of the electrode socket 3 achieves the clamping connection between the electrode socket 3 and the electrode plug 2 through the cooperation of specific components, ensuring the stability of the connection.
[0051] like Figure 10As shown, the limiting component 63 includes a concave frame 631. The concave frames 631 are fixedly installed at the bottom of the electrode sheet plug 2 in an equidistant annular arrangement. An elastic insulating limiting rod 632 is hinged inside the concave frame 631, and a linkage rod 633 is fixedly installed inside the elastic insulating limiting rod 632. Specifically, the elastic insulating limiting rod 632 is shaped like a reverse L. As Figure 6 and Figure 10 As shown, the movable component 61 includes a limiting rubber ring 611 and a movable sleeve 612. The movable sleeve 612 is slidably connected to the outer surface of the electrode insertion rod 62. The limiting rubber ring 611 is fixedly installed at the upper end of the electrode insertion rod 62. An annular card slot 613 is formed inside the movable sleeve 612. The shape of the annular card slot 613 is adapted to the shape of the limiting rubber ring 611. A conical guide groove 614 is formed at the top of the movable sleeve 612. The bottom of the limiting rubber ring 611 is conical. As Figure 9 As shown, an anti-detachment ring 615 is fixedly connected to the lower end of the outer surface of the electrode insertion rod 62. The diameter range of the anti-detachment ring 615 is 0.2 cm - 0.5 cm, and the inner diameter range of the electrode sleeve 4 is 0.21 cm - 0.51 cm. The inner diameter of the electrode sleeve 4 is larger than the diameter of the anti-detachment ring 615, which can ensure that the anti-detachment ring 615 can stably enter the inside of the electrode sleeve, and can ensure that the electrode insertion rod 62 and the electrode sleeve 4 are electrically connected. Again, as Figure 10 As shown, a conical inclined surface 616 is formed at the top of the movable sleeve 612, and the outside of the conical inclined surface 616 abuts against the bottom of the linkage rod 633.
[0052] During the installation of the electrode sheet plug 2 when the device is in use, the movable sleeve 612 slides down due to gravity, and the movable sleeve 612 is stuck on the anti-detachment ring 615, so that the movable sleeve 612 will not detach from the electrode insertion rod 62. The elastic insulating limiting rod 632 hinged inside the concave frame 631 is squeezed to expand outwards. The elastic insulating limiting rod 632 is shaped like a reverse L, which is convenient for squeezing it to expand. During the insertion process of the electrode sheet plug 2 and the electrode sheet socket 3, the electrode sleeve 4 pushes the movable sleeve 612 to move upwards. At this time, the conical guide groove 614 at the top of the movable sleeve 612 and the cone at the bottom of the limiting rubber ring 611 interact, causing the limiting rubber ring 611 to deform and enter the annular card slot 613 inside the movable sleeve 612, realizing the fixation of the movable sleeve 612. When the movable sleeve 612 moves upwards, the conical inclined surface 616 at its top squeezes the linkage rod 633, and the linkage rod 633 drives the elastic insulating limiting rod 632 to rotate inwards. The lower part of the elastic insulating limiting rod 632 moves axially towards the electrode insertion rod 62, and the lower part of the elastic insulating limiting rod 632 abuts against the electrode sleeve 4. After use, when the plug is pulled out, the movable sleeve 612 is fixed at the upper end of the insulating limiting rod due to the clamping with the limiting rubber ring 611, continuously squeezing the linkage rod 633, so that the elastic insulating limiting rod 632 remains closed and tightly covers the electrode insertion rod 62 (as Figure 8 As shown), to prevent re-insertion, the diameter of the anti-falling ring 615 is smaller than the inner diameter of the electrode sleeve 4, ensuring that the anti-falling ring 615 can smoothly enter the electrode sleeve 4, ensuring that the electrode rod 62 and the electrode sleeve 4 are conductive.
[0053] like Figures 1 to 4 As shown, the anti-fall mechanism 7 includes an annular groove 71 and a top card group 72. The top card group 72 is fixedly connected to the lower end of the outer surface of the outer sleeve 5. The annular groove 71 is opened at the top of the base 1 and is located outside the electrode sheet socket 3. One end of the torsion spring 74 is fixedly connected to the inside of the annular groove 71, and the other end of the torsion spring 74 is fixedly connected to the bottom card group 73. Figure 3 As shown, the top card group 72 includes a fixing ring 721, and protrusions 722 are fixedly installed at equal intervals on the outer side of the fixing ring 721. A through groove 723 is opened in the middle of the protrusion 722, and an arc-shaped limit pin 724 is fixedly connected to the bottom of the protrusion 722. The end of the arc-shaped limit pin 724 is inserted into the inner side of the bottom card group 73. When installing the electrode plug 2 and the electrode socket 3, by rotating the fixing ring 721 in the top card group 72, the protrusion 722 and the arc-shaped limit pin 724 are driven to rotate together, and the arc-shaped limit pin 724 squeezes the bottom card group 73, so that the bottom card group 73 rotates in the annular groove 71 and compresses the torsion spring 74.
[0054] At this point, the arc-shaped limit pin 724 is separated and misaligned from the bottom card group 73, allowing the electrode plug 2 to be smoothly plugged into the electrode socket 3. After the disposable locking mechanism 6 is triggered, the through groove 723 in the middle of the protrusion 722 cooperates with the specific support rod 733 to prevent the electrode plug 2 and the electrode socket 3 from rotating after being plugged in, thereby achieving preliminary limit fixation. After the plugging is completed, the fixing ring 721 is loosened, and the torsion spring 74 resets and pushes the bottom card group 73 to rotate back to its original position. The rotation of the bottom card group 73 drives the arc-shaped limit sleeve 732 inside it to move, so that it is adaptively sleeved on the outside of the arc-shaped limit pin 724. Through the mutual sleeve-limiting of the arc-shaped limit sleeve 732 and the arc-shaped limit pin 724, the top card group 72 is firmly clamped to the top of the bottom card group 73, thereby stably fixing the electrode plug 2 inside the electrode socket 3, effectively preventing accidental detachment during use.
[0055] like Figures 1 to 4As shown, the bottom card assembly 73 includes a slip ring 731, which is rotatably connected to the top of the annular groove 71. The bottom of the slip ring 731 is fixedly connected to the top of the torsion spring 74. The outer side of the slip ring 731 is fixedly connected to arc-shaped limit sleeves 732 arranged in an annular shape at equal intervals. The end of the arc-shaped limit pin 724 is inserted into the interior of the arc-shaped limit sleeve 732. The inner diameter of the arc-shaped limit sleeve 732 is larger than the outer diameter of the arc-shaped limit pin 724, allowing the arc-shaped limit sleeve 732 to be sleeved on the arc-shaped limit pin 724 or the arc-shaped limit sleeve 732 to be separated from the arc-shaped limit pin 724. The arc-shaped limit sleeve 732 and the arc-shaped limit pin 724 are both arranged concentrically with the torsion spring 74. The bottom card group 73 also includes a support rod 733 and an adjusting hand wheel 734. The support rods 733 are arranged in a ring at different levels and are fixedly installed on the top of the base 1. The end of the support rod 733 is slidably connected to the inside of the through groove 723, and the end of the support rod 733 passes through the through groove 723. The adjusting hand wheel 734 is fixedly connected to the outside of the arc-shaped limit sleeve 732. The outer surface of the adjusting hand wheel 734 is provided with anti-slip grooves 735 at equal intervals. When the disposable electrode anti-falling mechanism 7 of the defibrillator is working, the adjusting hand wheel 734 is rotated. Since the adjusting hand wheel 734 is fixed to the outside of the arc-shaped limit sleeve 732, the arc-shaped limit sleeve 732 is driven to rotate, and then the slip ring 731 connected to the arc-shaped limit sleeve 732 is rotated in the annular groove 71, and the bottom of the slip ring 731 squeezes the torsion spring 74 to compress it.
[0056] When the locking cam 732 is in the closed position, the locking cam 732 is in the closed position, and the locking cam 732 is in the closed position, so that the locking cam 732 is in the closed position. Figure 4 As shown), the top card group 72 is firmly connected to the top of the bottom card group 73 by setting a limit on each other, so that the electrode plug 2 is firmly fixed inside the electrode socket 3, effectively avoiding accidental falling off during use, and the anti-slip groove 735 on the outer surface of the adjustment handwheel 734 is convenient for operation and rotation, and the overall operation is convenient and stable.
[0057] The workflow of the technical solution provided by the present invention is as follows:
[0058] By designing a disposable locking mechanism 6, a reliable guarantee is provided for the safe use of the electrode piece, which can avoid the situation of reuse. In the initial state, when the electrode piece socket 3 and the electrode piece plug 2 have not been connected, the movable sleeve 612 is located between the limit exchange and the anti-falling ring 615. When installing the electrode piece plug 2 and the electrode piece socket 3, the electrode piece plug 2 is placed on the top of the electrode piece socket 3. When the electrode piece plug 2 and the outer sleeve 5 are in a vertical state, the movable sleeve 612 moves downward due to its own gravity, squeezing the elastic insulating limit rod 632, causing the elastic insulating limit rod 632 to rotate outward and be in an expanded state. At this time, the electrode piece plug 2 and the electrode piece socket 3 are plugged into each other and the motor sleeve squeezes the movable sleeve 612 to move it upward. During the upward movement, the conical guide groove 614 on the movable sleeve 612 and the conical bottom of the limiting rubber ring 611 guide each other, squeezing the limiting rubber ring 611 to deform it and enter the annular clamping groove 613, thereby clamping the movable sleeve 612 on the upper end of the outer surface of the electrode plug rod 62 at one time. At the same time, the main part of the electrode plug rod 62 is inserted into the electrode sleeve 4 inside the electrode sheet socket 3 to achieve power conduction. When the movable sleeve 612 moves upward, the conical inclined surface 616 on its top squeezes the linkage rod 633, and the linkage rod 633 drives the elastic insulating limiting rod 632 in the concave frame 631 to compress and rotate it inward. Since the electrode sheet plug 2 and the electrode sheet socket 3 have been plugged in at this time, the elastic insulating limiting rod 632 is deformed and fits on the outside of the electrode sleeve 4.
[0059] After use, when the electrode plug 2 and the electrode socket 3 are pulled out, the electrode sleeve 4 is pulled out from the elastic insulating limit rod 632. Because the movable sleeve 612 is limited by the annular groove 613 and the limiting rubber ring 611, the movable sleeve 612 is fixed to the upper end of the insulating limit rod, and the linkage rod 633 is continuously squeezed to keep the elastic insulating limit rod 632 in a closed state. After the insulating sleeve is pulled out, the elastic insulating limit rod 632 is completely closed and tightly covers the outside of the electrode plug rod 62 in a cone shape. At this time, even if you try to force the electrode plug 2 and the electrode socket 3 to be plugged in again, the elastic insulating limit rod 632 will only deform inwardly under the force, and due to the support and limitation of the electrode plug rod 62, it always stably covers the outside of the electrode plug rod 62, effectively preventing the electrode plug rod 62 and the electrode sleeve 4 from being plugged in and connected with each other, eliminating the violent plugging phenomenon from the root, and effectively avoiding the reuse of disposable electrode sheets.
[0060] The device is also provided with an anti-falling mechanism 7, which greatly improves the stability of use. When the electrode plug 2 and the electrode socket 3 need to be plugged into each other, the adjusting hand wheel 734 is turned to drive each arc-shaped limit sleeve 732 to rotate. During the rotation process, the arc-shaped limit sleeve 732 drives the slip ring 731 to rotate in the annular groove 71 and compress the torsion spring 74. When the torsion spring 74 is in a compressed state, the arc-shaped limit sleeve 732 is separated and misaligned from the arc-shaped limit pin 724. At this time, the electrode plug 2 and the electrode socket 3 can be smoothly plugged in. After the disposable locking mechanism 6 is triggered, the support rod 733 is inserted into the through groove 723 to prevent the electrode plug 2 and the electrode socket 3 from rotating after being plugged in, thereby achieving preliminary limit fixation.
[0061] After the electrode plug 2 and the electrode socket 3 are plugged in and installed, the adjusting hand wheel 734 is loosened, the torsion spring 74 is reset and the slip ring 731 is rotated back to its original position. The rotation of the slip ring 731 drives the outer arc-shaped limiting sleeves 732 to move so that they are adaptively sleeved on the outer side of the arc-shaped limiting pin 724. The arc-shaped limiting sleeves 732 and the arc-shaped limiting pin 724 are sleeved and limited with each other, and the fixing block and the fixing ring 721 are firmly clamped and installed on the top of the slip ring 731, thereby stably fixing the electrode plug 2 inside the electrode socket 3. This design makes the device whole. The body has strong installation stability, which effectively avoids accidental falling off during use, ensures stable and reliable operation during treatment, eliminates the hidden danger of the electrode being scrapped before treatment due to accidental falling off, and significantly improves the convenience of using the device. When it needs to be removed, it is only necessary to twist the adjustment handwheel 734 to drive the slip ring 731 to rotate, which can cause the arc-shaped limit sleeve 732 to rotate out of the inner side of the arc-shaped limit pin 724. At this time, the electrode socket 3 and the electrode plug 2 can be separated, so that it has better stability and is convenient for quickly adjusting and removing the electrode plug 2.
