Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of defibrillators, more particularly, to a defibrillator disposable electrode patch anti-reuse structure. BACKGROUND

[0002] In the medical emergency scene, the defibrillator is the key equipment to save the lives of patients with cardiac arrest, and the defibrillator electrode patch is an important component to connect the defibrillator and the patient's body and realize effective conduction of current. Its safety and reliability are crucial. Previously, in view of the many risks brought by the reuse of disposable electrode patches, such as increased risk of cross-infection, affecting defibrillation effect and even endangering patient's life, researchers have been committed to the research and development of corresponding anti-reuse structures.

[0003] Patent No. CN116832331B discloses a kind of anti-reuse structure for defibrillator electrode patch, which is designed by the unique cooperation of electrode patch plug and electrode patch socket, aiming to effectively prevent the reuse of electrode patch from the physical level without affecting the normal use of electrode patch;

[0004] However, this structure has exposed a series of problems in actual application. On the one hand, due to its one-time design, during the defibrillation operation, the medical staff may easily pull the lead due to inadvertent action when taking the electrode patch and attaching it to the patient's body, which may cause the electrode patch plug and the electrode patch socket to separate. Since the electrode patch is made of disposable material, it cannot be used again once it is separated, which may cause the electrode patch to be scrapped before the patient is treated, resulting in waste of resources and possible delay of the patient's rescue opportunity. On the other hand, the stability of the anti-reuse function of this structure is obviously insufficient. The electrode diameter of the electrode patch plug is much smaller than the inside of the blocking spring, and the blocking spring is made of elastic material. When misoperated, if the electrode patch plug is inserted into the electrode inside the electrode socket, the center column will press the blocking spring, and the blocking spring will deform, thus being set outside the electrode of the electrode socket. The electrode patch plug can still be inserted into the electrode inside the electrode socket, and the disposable use function cannot be stably realized. Even if the operation is standardized, if the user forces the electrode patch plug and the electrode socket, the electrode patch plug and the electrode socket may still be closed. In addition, this structure lacks anti-falling design. In actual use, the connection between the electrode patch plug and the electrode socket may be accidentally separated due to various external factors, further affecting the stability and reliability of the defibrillator electrode patch. These problems seriously restrict the effective application of the anti-reuse structure in actual medical scenes, and therefore need to be improved. SUMMARY

[0048] As Figures 1 to 10As shown in the figure, the defibrillator disposable electrode piece anti-reuse structure provided by the embodiment of the application comprises a base 1 and an electrode piece plug 2, the top of the base 1 is fixedly installed with an electrode piece socket 3, the inside of the electrode piece socket 3 is fixedly installed with an electrode sleeve 4, the electrode piece plug 2 is arranged directly above the electrode piece socket 3, the bottom of the electrode piece plug 2 is fixedly installed with an outer sleeve 5, the outer sleeve 5 is wrapped on the outside of the electrode piece socket 3, the inside of the outer sleeve 5 is movably installed with a disposable locking mechanism 6, the outside of the electrode piece socket 3 is fixedly installed with an anti-falling mechanism 7, the bottom of the anti-falling mechanism 7 is connected with the top of the base 1, and the electrode piece socket 3 and the electrode piece plug 2 are clamped through the anti-falling mechanism 7.

[0049] As shown in the figure, Figures 5 to 9 The disposable locking mechanism 6 comprises a movable assembly 61, an electrode plug rod 62 and a limiting assembly 63, the electrode plug rod 62 is fixedly installed at the bottom of the electrode piece plug 2 and located inside the outer sleeve 5, the movable assembly 61 is arranged on the outer surface of the electrode plug rod 62, the limiting assembly 63 is arranged in a ring shape at equal intervals on the upper end inside the outer sleeve 5, the top of the limiting assembly 63 is connected with the bottom of the electrode piece socket 3, and the limiting assembly 63 is arranged on the outside of the electrode plug rod 62 and the movable assembly 61.

[0050] As shown in the figure, Figure 5 and Figure 6 When installed, the electrode piece plug 2 is arranged on the top of the electrode piece socket 3, the movable assembly 61 in the disposable locking mechanism 6 extrudes the elastic insulation limiting rod 632 in the limiting assembly 63 to make it expand, the electrode piece plug 2 is inserted with the electrode piece socket 3, the electrode sleeve 4 extrudes the movable assembly 61 to move upwards, the movable assembly 61 is clamped on the upper end of the electrode plug rod 62 through a specific structure, and power conduction is realized. At the same time, the movable assembly 61 extrudes the linkage rod 633 to make the elastic insulation limiting rod 632 rotate and fit the electrode sleeve 4, the electrode piece plug 2 is pulled out from the electrode piece socket 3 after use, the movable assembly 61 is fixed on the insulation limiting rod, the elastic insulation limiting rod 632 is closed to tightly cover the electrode plug rod 62, and reinsertion is prevented to realize anti-reuse. In addition, the anti-falling mechanism 7 on the outside of the electrode piece socket 3 realizes the clamping of the electrode piece socket 3 and the electrode piece plug 2 through the cooperation of specific components, and the stability of the connection is ensured.

[0051] As shown in the figure, Figure 10As shown, the limiting component 63 includes a concave frame 631, and the concave frames 631 are fixedly installed at the bottom of the electrode sheet plug 2 in an equidistant and 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, and the shape of the annular card slot 613 is adapted to the shape of the limiting rubber ring 611. A conical guiding groove 614 is formed at the top of the movable sleeve 612, and the bottom of the limiting rubber ring 611 is conical. As Figure 9 As shown, an anti-drop-off 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-drop-off 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-drop-off ring 615, which can ensure that the anti-drop-off 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 during the use of this device, the movable sleeve 612 slides down due to gravity, and the movable sleeve 612 is stuck on the anti-drop-off ring 615, so that the movable sleeve 612 will not break away 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 guiding 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 fits 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 to keep the elastic insulating limiting rod 632 closed and tightly covering the electrode insertion rod 62 (asFigure 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 clamping group 73 includes a sliding ring 731 rotatably connected to the top of the annular groove 71, the bottom of the sliding ring 731 is fixedly connected to the top of the torsional spring 74, arc-shaped limiting sleeves 732 are fixedly connected to the outer side of the sliding ring 731 at equal intervals in a ring shape, the end of the arc-shaped limiting pin 724 is inserted into the interior of the arc-shaped limiting sleeve 732, and the inner diameter of the arc-shaped limiting sleeve 732 is greater than the outer diameter of the arc-shaped limiting pin 724, so that the arc-shaped limiting sleeve 732 can be sleeved on the arc-shaped limiting pin 724 or separated from the arc-shaped limiting pin 724. The arc-shaped limiting sleeve 732 and the arc-shaped limiting pin 724 are arranged in concentric circles with the torsional spring 74. The bottom clamping group 73 further includes support rods 733 and an adjusting hand wheel 734, the support rods 733 are fixedly installed on the top of the base 1 at equal intervals in a ring shape, the end of the support rod 733 is slidably connected to the interior of the through groove 723, the end of the support rod 733 penetrates through the through groove 723, and the adjusting hand wheel 734 is fixedly connected to the outer side of the arc-shaped limiting sleeve 732. A plurality of anti-skid grooves 735 are formed in the outer surface of the adjusting hand wheel 734 at equal intervals. When the defibrillator disposable electrode patch anti-falling mechanism 7 works, the adjusting hand wheel 734 is rotated, the arc-shaped limiting sleeve 732 is driven to rotate because the adjusting hand wheel 734 is fixed to the outer side of the arc-shaped limiting sleeve 732, and the sliding ring 731 connected to the arc-shaped limiting sleeve 732 rotates in the annular groove 71, and the sliding ring 731 presses the torsional spring 74 to compress.

[0056] At this time, the arc-shaped limiting sleeve 732 and the arc-shaped limiting pin 724 arranged in concentric circles are separated and misaligned, which creates conditions for the plug-in connection of the electrode patch plug 2 and the electrode patch socket 3. After the electrode patch plug 2 and the electrode patch socket 3 are plugged in, the disposable locking mechanism 6 is triggered, the ends of the support rods 733 arranged at equal intervals on the top of the base 1 slide into the through groove 723 in the middle of the protruding block 722, the plug and the socket are prevented from rotating after being plugged in, and preliminary limiting is achieved; after installation is completed, the adjusting hand wheel 734 is loosened, the torsional spring 74 is reset to drive the sliding ring 731 to rotate reversely and return to the original position, the sliding ring 731 drives the arc-shaped limiting sleeve 732 on the outer side to move until the arc-shaped limiting sleeve 732 is adaptively sleeved on the outer side of the arc-shaped limiting pin 724 (as shown in the figure), and the electrode patch plug 2 is firmly fixed in the electrode patch socket 3 by limiting through mutual sleeving of the arc-shaped limiting sleeve 732 and the arc-shaped limiting pin 724. Figure 4 The anti-skid grooves 735 on the outer surface of the adjusting hand wheel 734 facilitate the rotation of the adjusting hand wheel 734, and the overall operation is convenient and stable.

[0057] The working process of the technical scheme provided in the present application is as follows:

[0058] The one-time locking mechanism 6 is designed to provide reliable safety for the use of the electrode sheet, and to avoid its reuse. In the initial state, when the electrode sheet socket 3 and the electrode sheet plug 2 are not connected, the movable sleeve 612 is located between the limiting exchange and anti-falling ring 615. When installing the electrode sheet plug 2 and the electrode sheet socket 3, the electrode sheet plug 2 is placed on the top of the electrode sheet socket 3. When the electrode sheet plug 2 and the outer sleeve 5 are in a vertical state, the movable sleeve 612 moves downward due to its own gravity, extruding the elastic insulating limiting rod 632, which rotates outward to an unfolded state. At this time, the electrode sheet plug 2 and the electrode sheet socket 3 are inserted and sleeved with each other. The motor sleeve extrudes the movable sleeve 612 to move it upward. In the process of moving the movable sleeve 612 upward, the tapered guide groove 614 on the movable sleeve 612 and the tapered bottom of the limiting rubber ring 611 guide each other, extruding the limiting rubber ring 611 to deform and enter the annular clamping groove 613, thereby one-time clamping the movable sleeve 612 on the outer surface of the electrode rod 62. At the same time, the main part of the electrode rod 62 is inserted into the electrode sleeve 4 inside the electrode sheet socket 3 to realize power conduction. When the movable sleeve 612 moves upward, the tapered slope 616 on the top of the movable sleeve 612 extrudes the linkage rod 633, which drives the elastic insulating limiting rod 632 in the concave frame 631 to compress and rotate inward. Since the electrode sheet plug 2 and the electrode sheet socket 3 have been inserted at this time, the deformed elastic insulating limiting rod 632 is attached to the outside of the electrode sleeve 4.

[0059] After use, when the electrode sheet plug 2 and the electrode sheet socket 3 are pulled out, the electrode sleeve 4 is pulled out from the elastic insulating limiting rod 632. Since the movable sleeve 612 is limited by the annular clamping groove 613 and the limiting rubber ring 611, the movable sleeve 612 is fixed on the upper end of the insulating limiting rod, continuously extruding the linkage rod 633 to keep the elastic insulating limiting rod 632 in a closed state. After the insulating sleeve is pulled out, the elastic insulating limiting rod 632 is completely closed and tightly covers the outside of the electrode rod 62 in a conical shape. At this time, even if you try to force the electrode sheet plug 2 and the electrode sheet socket 3 to be inserted again, the elastic insulating limiting rod 632 will only deform inward under stress, and due to the support and limitation of the electrode rod 62, it will always stably cover the outside of the electrode rod 62, effectively preventing the electrode rod 62 and the electrode sleeve 4 from being inserted and connected, and fundamentally eliminating the phenomenon of violent insertion and avoiding the reuse of disposable electrode sheets.

[0060] The device is also provided with anti-falling mechanism 7, greatly improve the stability of use, when the electrode piece plug 2 and electrode piece socket 3 need to be inserted with each other, rotate the adjusting hand wheel 734, drive each arc-shaped limiting sleeve 732 to rotate, in the rotating process, the arc-shaped limiting sleeve 732 drives the slip ring 731 to rotate and compress the torsion spring 74, when the torsion spring 74 is in the compressed state, the arc-shaped limiting sleeve 732 is separated from the arc-shaped limiting pin 724 and is misaligned, at this time, the electrode piece plug 2 and the electrode piece socket 3 can be smoothly inserted, the one-time locking mechanism 6 is triggered, the supporting rod 733 is inserted into the through groove 723, preventing the electrode piece plug 2 and the electrode piece socket 3 from rotating after being inserted, and achieving preliminary limiting and fixing.

[0061] After the electrode piece plug 2 and the electrode piece socket 3 are inserted and installed, the adjusting hand wheel 734 is loosened, the torsion spring 74 resets and pushes the slip ring 731 to rotate back to the original position, the rotation of the slip ring 731 drives each arc-shaped limiting sleeve 732 on the outside to move, so that it is adaptively sleeved on the outside of the arc-shaped limiting pin 724, the fixed block and the fixed ring 721 are stably clamped and installed on the top of the slip ring 731 through the mutual sleeving and limiting of the arc-shaped limiting sleeve 732 and the arc-shaped limiting pin 724, and then the electrode piece plug 2 is stably fixed in the electrode piece socket 3, this design makes the device as a whole have strong installation stability, effectively avoids accidental falling during use, ensures stable and reliable operation during treatment, eliminates the hidden danger that the electrode piece is scrapped due to accidental falling before treatment, significantly improves the convenience of using the device, and when it is necessary to remove, only the adjusting hand wheel 734 needs to be twisted to drive the slip ring 731 to rotate, so that the arc-shaped limiting sleeve 732 rotates and separates from the inside of the arc-shaped limiting pin 724, at this time, the electrode piece socket 3 and the electrode piece plug 2 can be separated, so that they have good stability and are convenient for quickly adjusting and removing the electrode piece plug 2.
