[0002] Temporary pacemakers are widely used, mainly to meet the following three needs:

[0003] (1) Preventive needs: Applicable to any patient with potential temporary pacing protection needs, such as patients in the perioperative period of surgical valve replacement, transcatheter valve intervention, radiofrequency ablation of heart rate indicators, permanent pacemaker infection removal, hypertrophic myocardium and surgical resection or chemical ablation.

[0004] (2) Therapeutic needs: any patient who requires temporary pacing treatment, such as patients with pacing indications due to any surgical procedure, patients whose recovery is unpredictable, patients with acute myocardial infarction, patients after percutaneous coronary intervention, etc.

[0023] Compared with the prior art, the electrode lead connection device and temporary pacemaker of the present invention have the following advantages:

[0024] The aforementioned connecting device of the electrode wire includes a conductive block and an insulating bushing arranged along its axial direction; the connecting device has a penetration channel extending along its axial direction, the penetration channel passes through the conductive block and extends to the insulating bushing; the insulating bushing includes a first sleeve and a second sleeve sleeved on at least part of the outer surface of the first sleeve; the connecting device also includes at least one transition structure, the transition structure includes a through hole, a trigger body and a matching body; the through hole is provided on the first sleeve and communicates with the penetration channel; the trigger body is partially provided in the through hole and can move in a direction close to or away from the axis of the penetration channel; the matching body is provided between the first sleeve and the second sleeve The invention relates to a device for a temporary pacemaker, wherein the trigger body is provided between the trigger body and the conductive elastic member. The conductive elastic member is located at the through hole and is used to contact the trigger body. At least part of the trigger body of the transition structure is a conductive trigger body. When the transition structure is in a first state, the trigger body partially extends into the penetration channel, and the conductive elastic member and the conductive bonding member are separated from each other. When the transition structure switches from the first state to the second state, the trigger body moves in a direction away from the axis of the penetration channel under the action of an external force, and drives the conductive elastic member to deform and contact the conductive bonding member, and store elastic potential energy. When the conductive elastic member releases the potential energy, the transition structure switches to the first state.

The electrical component and the connecting device are both arranged on the housing, the first wire connects the electrical component and the conductive block, and the second wire connects the electrical component and the designated conductive bonding member of the connecting device. The configuration of the connecting device allows, when the conductive trigger body moves in a direction away from the axis of the passage until the conductive elastic member corresponding to the conductive trigger body contacts the conductive coupling member, one electrode of the standard IS-1 electrode lead can be electrically connected to the electrical component through the conductive block and the first lead, and the other electrode can be electrically connected to the electrical component through the conductive trigger body, the corresponding matching body and the second lead, thereby achieving the adaptation of the temporary pacemaker to the standard IS-1 electrode lead; and by making the conductive block contact with the electrode of the temporary pacing floating electrode alone, the adaptation of the temporary pacemaker to the temporary pacing floating electrode lead can be achieved. Similarly, by making the conductive block contact with the epicardial temporary pacing electrode lead alone, the adaptation of the temporary pacemaker to the epicardial temporary pacing electrode lead can be achieved. Thus, the temporary pacemaker equipped with the connecting device can be adapted to different electrode leads, greatly expanding the application scenarios of a single temporary pacemaker, and facilitating doctors to select appropriate measures for prevention or treatment based on the actual situation of the patient.

[0025] Furthermore, some of the transition structures are first transition structures, and some of the transition structures are second transition structures.

[0055] One object of the present invention is to provide an electrode lead connection device that can simultaneously accommodate multiple electrode leads, including standard IS-1 electrode leads, temporary pacing floating electrode leads, and epicardial temporary pacing electrode leads. Thus, when the connection device is installed on a temporary pacemaker, the temporary pacemaker can be adapted to different electrode leads, effectively expanding the indications and application scenarios of a single temporary pacemaker. A second object of the present invention is to provide a temporary pacemaker equipped with the aforementioned electrode lead connection device.

[0056] To make the objects, advantages, and features of the present invention more apparent, the present invention is further described below in detail with reference to the accompanying drawings. It should be noted that the drawings are greatly simplified and not to exact scale, and are intended solely to facilitate and clearly illustrate the embodiments of the present invention. The same or similar reference numerals in the drawings represent the same or similar components.

[0057] To facilitate understanding of the present invention, the structures of a temporary pacemaker, a standard IS-1 electrode lead, a temporary pacing floating electrode lead, and an epicardial temporary pacing electrode lead are briefly introduced.

[0058] Referring to FIG1 , the temporary pacemaker includes a housing 10, a connecting device 20, an electrical component 30, and a wire 40. The connecting device 20 and the electrical component 30 are both disposed on the housing 10 and are electrically connected to each other via the wire 40. The electrical component 30 includes a wireless communication module, such as a Bluetooth communication module, a radio frequency communication module, or a Wi-Fi module, which performs functions such as pacing, sensing, and heart rate response. During operation of the temporary pacemaker, the electrical component 30 adjusts the operating parameters of the pacemaker.

[0059] Referring to Figures 5 and 15 , the standard IS-1 electrode lead includes two electrodes, a first electrode 01 and a second electrode 02. The first electrode 01 and the second electrode 02 are arranged along the axis of the standard IS-1 electrode lead and extend along the axis of the standard IS-1 electrode lead. The end of the first electrode 01 away from the second electrode 02 is a free end. The first electrode 01 and the second electrode 02 are connected by an insulating spacer 03. When the standard IS-1 electrode lead is connected to a temporary pacemaker via a connecting device 20, both the first electrode 01 and the second electrode 02 should be electrically conductive with the electrical component 30 of the temporary pacemaker through the connecting device 20.

[0060] Referring to Figures 6, 7, 16, and 17, the epicardial temporary pacing lead includes an electrode, referred to as third electrode 04. Third electrode 04 is longer and thinner than the two electrodes of a standard IS-1 lead. When the epicardial temporary pacing lead is connected to a temporary pacemaker via connector 20, third electrode 04 is electrically conductive with electrical assembly 30 via connector 20.

[0061] Referring to Figures 8 and 18 , the temporary pacing floating electrode includes an electrode, referred to as fourth electrode 05. Fourth electrode 05 is shorter and thicker than first electrode 01 of a standard IS-1 electrode lead. When the temporary pacing floating electrode lead is connected to the temporary pacemaker via connector 20, fourth electrode 05 is electrically connected to electrical assembly 30 via connector 20.

[0062] Next, the specific structure of the connection device 20 is described in conjunction with specific embodiments. It should be noted that the following description only lists possible configurations of the connection device 20, but does not exhaust all optional configurations of the connection device 20, and therefore should not constitute an undue limitation to the present invention.

[0063] <Example 1>

[0064] Figure 2 shows an exploded schematic diagram of a connection device 20 provided in this embodiment, and Figures 3 and 4 show cross-sectional views of another connection device 20 provided in this embodiment. Referring to Figures 2 to 4, the connection device 20 includes a conductive block 1000 and an insulating bushing 2000 arranged along its axial direction. The connection device 20 has a through-channel (not labeled) extending along its axial direction. The through-channel passes through the conductive block 1000 and extends to the insulating bushing 2000. In an optional implementation, the through-channel passes through the insulating bushing 2000.

[0065] The insulating bushing 2000 includes a first sleeve body 2100 and a second sleeve body 2200 . The second sleeve body 2200 is sleeved on at least a portion of the outer surface of the first sleeve body 2100 .

[0066] The connecting device 20 also includes at least one adapter structure (not labeled in the figures). The number of adapter structures can be adjusted as needed. For example, as shown in Figures 2 to 4, there is one adapter structure in Figure 2, while there are three adapter structures in Figures 3 and 4. The cross-sectional view of Figure 2 can refer to Figures 3 and 4, with the only difference being the number of adapter structures. Each adapter structure includes a through hole 3100, a trigger body (including the conductive trigger body 3210 described below), and a matching body 3300. The through hole 3100 is provided in the first housing 2100 and communicates with the through-hole. The trigger body is partially disposed within the through hole 3100 and is capable of moving toward or away from the axis of the through-hole. The matching body 3300 is disposed between the first housing 2100 and the second housing 2200 and includes a corresponding conductive elastic member 3310 and a conductive bonding member 3320. The conductive elastic member 3310 is disposed at the through hole 3100 and contacts the trigger body.

[0067] The switching structure has a first state and a second state, and the switching structure can switch between the first state and the second state. For any switching structure, when the switching structure is in the first state, as shown in Figure 3, the trigger body partially extends into the penetration channel, and the conductive elastic member 3310 and the conductive bonding member 3320 are separated from each other. When the trigger body is subjected to a force in a direction away from the axis of the penetration channel, the trigger body is driven to move in a direction away from the axis of the penetration channel, and the trigger body also drives the conductive elastic member 3310 to deform, causing the conductive elastic member 3310 to contact the conductive bonding member 3320, causing the switching structure to switch to the second state. It can be understood that during the process of switching the switching structure from the first state to the second state, the conductive elastic member 3310 stores elastic potential energy. It can also be understood that when the force acting on the trigger body in a direction away from the axis of the penetration channel is canceled and the conductive elastic member 3310 releases its elastic potential energy, part of the conductive elastic member 3310 moves in the opposite direction to its original position due to its own elastic action. The conductive elastic member 3310 also drives the trigger body to move in a direction toward the penetration channel to its original position, causing the adapter structure to switch back to the first state. The aforementioned "force in a direction away from the axis of the penetration channel" is provided by a structure inserted into the penetration channel, such as the first electrode 01 of a standard IS-1 electrode lead or the second electrode 04 of an epicardial temporary pacing electrode lead.

[0068] In this embodiment, the trigger bodies of all transition structures are made of a conductive material and are referred to as conductive trigger bodies 3210. Accordingly, the second housing 2200 is provided with at least one window 2210, which corresponds to at least one transition structure. Specifically, each window 2210 corresponds to a conductive bonding member 3320 of a transition structure, and each conductive bonding member 3320 of the transition structure is partially exposed at the corresponding window 2210.

[0069] Referring back to Figure 1 , the temporary pacemaker's lead 40 includes a first lead 41 and a second lead 42. When the connection device 20 provided in this embodiment is attached to the temporary pacemaker, the conductive block 1000 is connected to the electrical assembly 30 via the first lead 41. The conductive connector 3320 of any transition structure is electrically connected to the second lead 42 at the corresponding window 2210, and is also electrically connected to the electrical assembly 30 via the second lead 42. When used, a temporary pacemaker equipped with the connection device 20 provided in this embodiment can be compatible with a standard IS-1 electrode lead, an epicardial temporary pacing electrode lead, or a temporary floating pacing electrode lead.

[0070] Specifically, referring to Figure 5 , when a temporary pacemaker is adapted for use with a standard IS-1 electrode lead, the first electrode 01 is inserted into the insulating sleeve 2000 along the passageway and contacts at least one conductive triggering body 3210. A force is applied to the contacting conductive triggering body 3210 in a direction away from the axis of the passageway. Consequently, the at least one conductive triggering body 3210 moves in a direction away from the axis of the passageway, causing the corresponding adapter structure to switch to the second state. Consequently, the first electrode 01 of the standard IS-1 electrode lead can connect to the second lead 42 through the contacting conductive triggering body 3210 and the corresponding mating body 3300, thereby electrically conducting with the electrical component 30. Simultaneously, the second electrode 02 of the standard IS-1 electrode lead is located within and connected to the conductive block 1000, and can electrically conduct with the electrical component 30 through the conductive block 1000 and the first lead 41.

[0071] Referring to FIG6 , when the temporary pacemaker is adapted for an epicardial temporary pacing electrode lead, the third electrode 04 is partially inserted into the insulating sleeve 2000 along the insertion channel and partially located within the conductive block 1000. Ideally, the third electrode 04 maintains a straight configuration and does not contact the conductive triggering body 3210 of any transition structure. In this manner, the third electrode 04 only contacts the conductive block 1000 and is electrically conductive with the electrical assembly 30 via the conductive block 1000, the first lead 41, and the electrical assembly 30, allowing the temporary pacemaker to function normally. It should be understood that, as shown in FIG7 , when the third electrode 04 is slightly bent, causing it to contact the conductive triggering body 3210 of a portion of the transition structure, but the conductive triggering body 3210 does not move to contact the corresponding conductive elastic member 3310 and the conductive bonding member 3320, the third electrode 04 is not electrically conductive with the electrical assembly 30 via the second lead 42. In this case, the temporary pacemaker can still be used. However, if the third electrode 04 bends significantly and at least one of the conductive triggering bodies 3210 of the transition structure moves under the action of the third electrode 04 until the corresponding conductive elastic member 3310 contacts the conductive bonding member 3320, the third electrode 04 can then be electrically connected to the electrical component 30 via the matching body 3300 and the second wire 42. In this case, the temporary pacemaker cannot be used normally and the third electrode 04 needs to be removed from the insertion channel and reinserted.

[0072] Referring to Figure 8 , when the temporary pacemaker is fitted with a temporary pacing floating electrode lead, the fourth electrode 05 partially extends along the passageway into the insulating sleeve 2000 and is partially located within the conductive block 1000. The free end of the fourth electrode 05 is located on the side of the conductive trigger body 3210 of the adapter structure that is close to the conductive block 1000. Thus, the fourth electrode 05 is connected to the conductive block 1000 and is electrically conductive to the electrical component 30 via the first lead 41.

[0073] Therefore, when the connection device 20 provided in this embodiment is applied to a temporary pacemaker, the temporary pacemaker can be applicable to a variety of electrode leads including standard IS-1 electrode leads, epicardial temporary pacing electrode leads, and temporary pacing floating electrode leads, thereby expanding the indications and scope of application of a single temporary pacemaker.

[0074] Next, the various components of the connecting device 20 provided in this embodiment are described in detail.

[0075] Please refer back to Figure 2. The conductive block 1000 includes a conductive block body 1100 and a fastener 1200. The conductive block body 1100 is provided with a first channel 1110 extending axially through the connecting device 20, and the first channel 1110 constitutes a part of the through-channel. In this embodiment, the first channel 1110 is a slot-shaped structure with an open upper end. The conductive block body 1100 is also provided with a mounting hole 1120, which is connected to the first channel 1110. The fastener 1200 is configured to be able to be passed through the mounting hole 1120 and extend into the conductive block body 1100. In practice, the mounting hole 1120 is a threaded hole, the fastener 1200 is a set screw, and the fastener 1200 is connected to the first wire 41. When any electrode (for example, the second electrode 02 of the standard IS-1 electrode lead, the third electrode 04 of the epicardial temporary pacing electrode lead, or the fourth electrode 05 of the temporary pacing electrode lead) is inserted into the first channel 1110, the fastener 1200 is used to press against the corresponding electrode to lock the position of the corresponding electrode, and also to make the corresponding electrode in close contact with the fastener 1200, thereby realizing electrical connection between the electrode and the first lead 41.

[0076] Referring to Figures 3 and 4 , at least one accommodating cavity 2010 is formed between the outer surface of the first housing 2100 and the inner surface of the second housing 2200. At least one accommodating cavity 2010 is correspondingly located with at least one adapter structure, and each adapter structure is positioned at a corresponding accommodating cavity 2010. Specifically, each through-hole 3100 is positioned in the first housing 2100 at a corresponding accommodating cavity 2010; and each mating body 3300 is at least partially positioned within the corresponding accommodating cavity 2010.

[0077] In this embodiment, to facilitate the creation of the accommodating cavity 2010 and the installation of the conductive trigger body 3210 and the matching body 3300, the first and second housings 2100 and 2200 are preferably separately processed and then assembled into one body. When unassembled, the second housing 2200 has a second channel 2201 extending axially therethrough, which is used to accommodate the first housing 2100. Furthermore, the first housing 2100 has a third channel 2101 extending axially therethrough, which constitutes a portion of the through-passage.

[0078] Optionally, referring to Figure 9 , a first mounting groove 2110 is provided on the outer side of the first housing 2100. As shown in Figure 10 , a second mounting groove 2220 is provided on the inner side of the second housing 2200. The second mounting groove 2220 corresponds to the first mounting groove 2110, so that the second mounting groove 2220 and the first mounting groove 2110 are spliced ​​to form the accommodating cavity 2010.

[0079] Furthermore, the through hole 3100 includes a tapered section (not labeled in the figure) that extends perpendicularly to the axis of the through hole and reaches the inner side of the first housing 2100. The cross-section of the tapered section gradually decreases as it approaches the axis of the through hole. Furthermore, the minimum cross-section of the tapered section is smaller than the maximum cross-section of the conductive trigger body 3210 perpendicular to the axis of the through hole 3100. This allows the wall of the tapered section to restrain the conductive trigger body 3210, preventing it from escaping from the through hole 3100 and fully entering the through hole. It should be understood that the cross-section of the tapered section refers to the cross-section of the through hole 3100 perpendicular to its axis. It should also be understood that the dimension of the accommodating cavity 2010 perpendicular to the axis of the through hole is smaller than the dimension of the conductive trigger body 3210 perpendicular to the axis of the through hole, thereby preventing the conductive trigger body 3210 from escaping from the through hole 3100 and fully entering the accommodating cavity 2010.

[0080] The conductive trigger body 3210 may have any suitable shape. In one non-limiting implementation, the conductive trigger body 3210 is a sphere.

[0081] Alternatively, referring back to Figure 2 , the conductive elastic member 3310 may be a sheet-like structure having opposing first and second ends 3311 and 3312. In one non-limiting embodiment, when the adapter structure is in the first state, the first and second ends 3311 and 3312 of the conductive elastic member are axially opposed to each other along the channel. The first end 3311 of the conductive elastic member and the insulating bushing 2000 remain stationary relative to each other. A portion between the first and second ends 3311 and 3312 of the conductive elastic member contacts the conductive trigger body 3210. The second end 3312 of the conductive elastic member is configured to move in a direction toward or away from the axis of the passage. Specifically, when the conductive trigger body 3210 moves in a direction away from the axis of the passage under a force acting in a direction away from the axis of the passage, the conductive trigger body 3210 drives the second end 3312 of the conductive elastic member to move in a direction away from the axis of the passage until the second end 3312 of the conductive elastic member contacts the conductive engagement member 3320 (i.e., the transition structure switches from the first state to the second state). During this process, the conductive elastic member 3310 stores elastic potential energy. When the force acting in a direction away from the axis of the passage on the conductive trigger body 3210 is removed and the conductive elastic member 3310 releases its elastic potential energy, the second end 3312 of the conductive elastic member moves in a direction toward the axis of the passage until it returns to its original position. Simultaneously, the conductive elastic member 3310 drives the conductive trigger body 3210 in a direction toward the axis of the passage until it returns to its original position (i.e., the transition structure switches from the second state to the first state).

[0082] When assembling the connecting device 20, the first end 3311 of the conductive elastic member can be connected to at least one of the first housing 2100 and the second housing 2200. Furthermore, the conductive bonding member 3320 can also be a sheet-like structure. Furthermore, when assembling the connecting device 20, the conductive bonding member 3320 can be connected to at least one of the first housing 2100 and the second housing 2200. In one exemplary implementation, the first end 3311 of the conductive elastic member 3310 can be clamped by the first housing 2100 and the second housing 2200, and any suitable position of the conductive bonding member 3320 can be clamped by the first housing 2100 and the second housing 2200.

[0083] <Example 2>

[0084] Figure 11 shows an exploded schematic diagram of a connection device 20 provided in this embodiment, and Figures 12 and 13 show cross-sectional views of another connection device 20 provided in this embodiment. The connection device 20 shown in Figure 11 includes one adapter structure, while the connection devices shown in Figures 12 and 13 include three adapter structures. The cross-sectional view of Figure 11 can refer to Figures 12 and 13, with the only difference being the number of adapter structures. As shown in Figures 11 to 13, this embodiment differs from the first embodiment in the structure of the conductive elastic member 3310.

[0085] Specifically, the conductive elastic member 3310 includes at least a deformable portion 3313 and a contact portion 3314 that are connected to each other. The deformable portion 3313 is configured to extend or contract in the direction of connection between the deformable portion 3313 and the contact portion 3314. The contact portion 3314 includes a guide slope (not labeled in the figure) that is inclined relative to the axis of the through hole 3100 and contacts the conductive trigger body 3210.

[0086] In practice, when the adapter structure is in the first state, the deformable portion 3313 and the contact portion 3314 are arranged axially along the passage. Simultaneously, the conductive bonding member 3320 is located on the side of the contact portion 3314 away from the deformable portion 3313. In other words, the contact portion 3314 is located on the side of the deformable portion 3313 closer to the conductive bonding member 3320. When the conductive trigger body 3210 is driven by a force in a direction away from the axis of the passage, the conductive trigger body 3210 applies a force in a direction away from the axis of the passage to the guide slope. Under the action of the guide slope, the contact portion 3314 moves in a direction closer to the conductive bonding member 3320, causing the deformable portion 3313 to stretch and lengthen, thereby bringing the conductive elastic member 3310 into contact with the conductive bonding member 3320.

[0087] Optionally, as shown in FIG14 , the deformable portion 3313 includes a sheet-like structure having a plurality of deformable grooves 3315 disposed thereon. The deformable grooves 3315 extend in a direction that intersects the connection direction between the contact portion 3314 and the deformable portion 3313. One end of the deformable grooves 3315 is open, and the open ends of two adjacent deformable grooves face away from each other. This deformable portion 3313 has a relatively small size and can be accommodated within the accommodating cavity 2010. When the contact portion 3314 moves toward the conductive coupling member 3320, the deformable portion 3313 deforms and elongates under the action of the deformable grooves. When the force applied to the conductive trigger body 3210 in a direction away from the axis of the passage is removed, the deformable portion 3313 can return to its original shape. In an exemplary implementation, an extension direction of the deformation groove 3315 is perpendicular to a connection direction between the contact portion 3314 and the deformation portion 3313 , and the deformation groove 3315 extends to an edge of the deformation portion 3313 .

[0088] FIG15 shows a schematic diagram of the connection device 20 provided in this embodiment, applied to a temporary pacemaker and adapted for use with a standard IS-1 electrode lead. The first electrode 01 is inserted into the insulating sleeve 2000 along the passageway, contacting at least one conductive triggering body 3210. A force is applied to the contacting conductive triggering body 3210 in a direction away from the axis of the passageway. As a result, the at least one conductive triggering body 3210 moves away from the axis of the passageway, causing the contact portion 3314 of the corresponding conductive elastic member 3310 to move away from the deformable portion 3313, stretching and lengthening the deformable portion 3313 until it contacts the conductive bonding member 3320.

[0089] Referring to FIG16 , when a temporary pacemaker is adapted for an epicardial temporary pacing electrode lead, the third electrode 04 is partially inserted into the insulating sleeve 2000 along the insertion channel and partially located within the conductive block 1000. Ideally, the third electrode 04 maintains a straight configuration and does not contact any of the conductive triggering bodies 3210 of the transition structure. In this manner, the third electrode 04 contacts only the conductive block 1000 and is connected to the electrical assembly 30 via the conductive block 1000 and the first lead 41, allowing the temporary pacemaker to function normally. As shown in FIG17 , in some cases, the third electrode 04 inserted into the insulating sleeve 2000 is in a bent state. If the third electrode 04 is slightly bent, causing it to contact a portion of the conductive triggering body 3210 of the transition structure, but the conductive triggering body 3210 does not move to the point where the corresponding conductive elastic member 3310 contacts the conductive bonding member 3320, the third electrode 04 is not connected to the electrical assembly 30 via the second lead 42. In this case, the temporary pacemaker can still be used. However, if the third electrode 04 bends significantly and at least one conductive triggering body 3210 of the transition structure moves under the action of the third electrode 04 until the corresponding conductive elastic member 3310 contacts the conductive bonding member 3320, the third electrode 04 will be connected to the electrical component 30 via the matching body 3300 and the second wire 42. In this case, the temporary pacemaker cannot be used normally and the third electrode 04 needs to be removed from the insertion channel and reinserted.

[0090] Referring to Figure 18 , when the temporary pacemaker is fitted with a temporary pacing floating electrode lead, the fourth electrode 05 partially extends along the passageway into the insulating sleeve 2000 and is partially located within the conductive block 1000. The free end of the fourth electrode 05 is located on the side of the conductive trigger body 3210 of the adapter structure that is close to the conductive block 1000. Thus, the fourth electrode 05 is connected to the conductive block 1000 and to the electrical component 30 via the first lead 41.

[0091] <Example 3>

[0092] This embodiment is a further improvement of the first embodiment, and can avoid miscommunication between the third electrode 04 or the fourth electrode 05 and the electrical component 30 when the temporary pacemaker is adapted to the epicardial temporary pacing electrode lead and the temporary pacing floating electrode lead.

[0093] For ease of distinction, in the description of this embodiment, the temporary pacemaker configured with the connecting device 20 provided in Example 1 is referred to as a first temporary pacemaker, and the temporary pacemaker configured with the connecting device 20 provided in this embodiment is referred to as a second temporary pacemaker.

[0094] In addition, to facilitate understanding of this embodiment, the misconduction of the third electrode 04 and the electrical component 30 when the first temporary pacemaker is adapted to the epicardial temporary pacing electrode lead, and the misconduction of the fourth electrode 05 and the electrical component 30 when the first temporary pacemaker is adapted to the temporary pacing floating electrode lead are first introduced.

[0095] For the case where the first temporary pacemaker is adapted to the epicardial temporary pacing electrode lead, there are two mis-conduction situations. Among them, the first mis-conduction situation is when the third electrode 04 is in a bent state after being inserted into the insulating sleeve 2000, and the bent third electrode 04 applies a force to the partial conductive trigger body 3210 in a direction away from the axis of the penetration channel, so that the corresponding conductive trigger body 3210 drives the partial structure of the conductive elastic part 3310 to move until the conductive elastic part 3310 is connected to the conductive bonding part 3320, so that the third electrode 04 is connected to the electrical component 30 through at least a partial conductive trigger body 3210, the corresponding matching body 3300 and the second wire 42. The second misconductance situation is that even if the third electrode 04 remains in a straight configuration or has a small bend after being inserted into the insulating sleeve 2000, if the third electrode 04 carries a large amount of conductive liquid into the insulating sleeve 2000, the conductive liquid may flow into the through hole 3100 and the receiving cavity 2010, causing the third electrode 04 to be electrically conductive with the conductive trigger body 3210 and the matching body 3300 through the conductive liquid. The conductive liquid can be, for example, physiological saline or blood.

[0096] When the first temporary pacemaker is adapted for the temporary pacing floating electrode, a misconnection condition occurs, referred to as the third misconnection condition. The third misconnection condition occurs when the fourth electrode 05 carries a large amount of conductive liquid during insertion into the insulating sleeve 2000. This conductive liquid may flow into the through-hole 3100 and the accommodating cavity 2010, causing electrical conduction between the fourth electrode 05 and the conductive triggering body 3210 and the matching body 3300 via the conductive liquid.

[0097] Next, the structure of the connecting device 20 provided in this embodiment is introduced.

[0098] Figure 19 shows an exploded schematic diagram of the connection device 20 provided in this embodiment, and Figures 20 and 21 are cross-sectional views of the connection device 20. As shown in Figures 19 and 21, in this embodiment, the connection device 20 includes multiple transition structures, some of which are first transition structures and others are second transition structures. The triggering body of the first transition structure is a conductive triggering body 3210, while the triggering body of the second transition structure is an insulating triggering body 3220 made of insulating material. Furthermore, only one window 2210 is provided on the second housing 2200. This window 2210 corresponds to a conductive bonding member 3320 of the second transition structure, such that the conductive bonding member 3320 of the second transition structure is exposed at the window 2210 and electrically connected to the electrical component 30 via the second conductive wire 42. Furthermore, when all transition structures are in the second state, the conductive elastic members 3310 and conductive bonding members 3320 of all transition structures are connected in series. This prevents the occurrence of the first type of misconnection. The specific principles will be described in detail later.

[0099] Optionally, as shown in Figures 20 and 21, all the transition structures are arranged at intervals along the circumference of the penetration channel, and the number of the first transition structure is one. All the transition structures are numbered along the circumference of the penetration channel, and the first transition structure is referred to as the first transition structure. The conductive bonding member 3320 of the nth transition structure is connected to the conductive bonding member 3320 of the n+1th transition structure, and the conductive elastic member 3310 of the n+1th transition structure is connected to the conductive elastic member 3310 of the n+2th transition structure. The window 2210 is arranged corresponding to the conductive bonding member 3320 of the last second transition structure, so that the conductive bonding member 3320 of the last second transition structure is partially exposed at the window 2210 and connected to the second wire 42. n is a positive integer greater than or equal to 1.

[0100] In one exemplary implementation, there are three transition structures, namely, one first transition structure and two second transition structures. The conductive bonding member 3320 of the first transition structure is connected to the conductive bonding member 3320 of the first second transition structure (i.e., the second transition structure), and the conductive elastic member 3310 of the first second transition structure is connected to the conductive elastic member 3310 of the second second transition structure (i.e., the third transition structure). The window 2210 is provided at the conductive bonding member 3320 of the second second transition structure, such that the conductive bonding member 3320 of the second second transition structure is partially exposed at the window 2210 and connected to the second wire 42.

[0101] When the connecting device 20 provided in this embodiment is applied to a second temporary pacemaker, and the second temporary pacemaker is adapted to a standard IS-1 electrode lead, the first electrode 01 of the standard IS-1 electrode lead is inserted into the insulating bushing 200 through the penetration channel, and the first electrode 01 simultaneously applies a force along the direction away from the axis of the penetration channel to the triggering bodies of the three adapter structures, so that the triggering bodies of the three adapter structures all move along the direction away from the axis of the penetration channel until the conductive elastic parts 3310 of the three adapter structures respectively contact the corresponding conductive coupling parts 3320, so that all the adapter structures are switched to the second state. In this way, the first electrode 01, the conductive trigger body 3210 of the first adapter structure, the conductive elastic member 3310 of the first adapter structure, the conductive bonding member 3320 of the first adapter structure, the conductive bonding member 3320 of the first second adapter structure, the conductive elastic member 3310 of the first second adapter structure, the conductive elastic member 3310 of the second second adapter structure, and the conductive bonding member 3320 of the second second adapter structure are connected in series in sequence and are electrically connected to the electrical component 30 via the second wire 42.

[0102] When the second temporary pacemaker is adapted to the epicardial temporary pacing electrode lead, the third electrode 04 is inserted into the insulating sleeve 200 through the insertion channel. Even if the third electrode 04 is bent and causes part of the transition structure to switch from the first state to the second state, for example, the first transition structure and the first second transition structure to switch to the second state, the second second transition structure has not switched to the second state, that is, the conductive elastic member 3310 and the conductive bonding member 3320 of the second second transition structure are disconnected. Therefore, the third electrode 04 cannot be electrically connected to the second lead 42. Similarly, when the third electrode 04 is bent and causes the first transition structure and the second second transition structure to switch to the second state, or causes both second transition structures to switch to the second state, the third electrode 04 cannot be electrically connected to the second lead 42.

[0103] In this embodiment, as shown in FIG19 , the conductive bonding member 3320 of the nth transition structure and the conductive bonding member 3320 of the n+1th transition structure are an integral structure. Specifically, in the implementation described in FIG19 to FIG21 (i.e., there are three transition structures, one of which is a first transition structure and the other two are second transition structures), the conductive bonding member 3320 of the first transition structure and the conductive bonding member 3320 of the first second transition structure are an integral structure. Of course, in an alternative implementation, the conductive bonding member of the nth transition structure and the conductive bonding member of the n+1th transition structure can also be a separate structure, connected by a bridging wire (not shown in the figure), which will not be described in detail here.

[0104] As shown in FIG19 , the conductive elastic member 3310 of the n+1th transition structure and the conductive elastic member 3310 of the n+2th transition structure are optionally integrated. Specifically, in the implementations shown in FIG19 to FIG21 , the conductive elastic member 3310 of the first second transition structure and the conductive elastic member 3310 of the second second transition structure are integrated. Alternatively, the conductive elastic member of the n+1th transition structure and the conductive elastic member of the n+2th transition structure may be separate structures, connected by a bridging wire (not shown in the figure), which will not be described in detail here.

[0105] Further preferably, in this embodiment, when the adapter structure is in the first state, each trigger body is sealed against the wall of the corresponding through hole 3100. This can reduce the flow of charged liquid into the through hole 3100, thereby reducing the occurrence of the second and third mis-conduction conditions.

[0106] Optionally, the hole wall of the through hole 3100 is coated with a sealant, such as silicone. In this way, when the adapter structure is in the first state, the trigger body is actually in contact with the silicone, so that the trigger body can be sealed with the hole wall of the through hole 3100 under the action of the silicone, thereby making it difficult for the conductive liquid brought into the penetration channel by the third electrode 04 or the fourth electrode 05 to enter the through hole 3100.

[0107] This embodiment does not specifically limit the formation method of the accommodating cavity 2010. It is sufficient as long as the formed accommodating cavity 2010 matches the structure and position of the adapter structure, so that the through hole 3100 of the adapter structure can be arranged in the area of ​​the first housing 2100 corresponding to the accommodating cavity 2010, and the matching body 3300 is located within the corresponding accommodating cavity 2010. In a specific implementation, at least two first mounting grooves 2110 are provided on the outer surface of the first housing 2100, and at least two second mounting grooves 2220 are provided on the inner surface of the second housing 2200. For example, as shown in Figures 19 to 21, the outer surface of the first housing 2100 has two first mounting grooves 2110, and the second housing 2200 has two second mounting grooves 2220. The two first mounting grooves 2110 are respectively the first mounting groove a and the first mounting groove b, and the two second mounting grooves 2220 are respectively the second mounting groove a and the second mounting groove b. The first mounting groove a cooperates with a portion of the second mounting groove a to form a receiving cavity 2010, a portion of the first mounting groove b cooperates with another portion of the second mounting groove a to form another receiving cavity 2010, and another portion of the first mounting groove b cooperates with the second mounting groove b to form yet another receiving cavity 2010. At least two first mounting grooves 2110 are isolated from each other, and at least two second mounting grooves 2220 are isolated from each other. Furthermore, when a portion of the conductive bonding member 3320 is clamped and fixed by the first and second housings 2100 and 2200, a sealant may be applied to the surface of the clamped portion of the conductive bonding member 3320 to enhance the seal between the conductive bonding member 3320 and the first and second housings 2100 and 2200. The advantage of doing so is that the amount of conductive liquid entering the accommodating cavity 2010 from the end of the insulating bushing 2000 close to the conductive block 1000 can be reduced, thereby reducing the possibility of the fitting body 3300 being electrically connected to the electrode through the conductive liquid.

[0108] The configuration of the conductive elastic member 3310 of the connecting device 20 provided in this embodiment can refer to the first embodiment and will not be described again here.

[0109] <Example 4>

[0110] Figure 22 shows an exploded view of the connection device 20 provided in this embodiment, and Figures 23 and 24 show cross-sectional views of the connection device 20 of this embodiment. As shown in Figures 22 to 24, the connection device 20 of this embodiment differs from the connection device 20 of the third embodiment in that the configuration of the conductive elastic member 3310 is different.

[0111] The specific configuration of the conductive elastic member 3310 in this embodiment can be referred to the second embodiment and will not be described in detail here.

[0112] 21 , the conductive elastic member 3310 of the n+1th transition structure and the conductive elastic member 3310 of the n+2th transition structure may be separate structures, connected by a bridging wire 3330. Alternatively, the conductive elastic member of the n+1th transition structure and the conductive elastic member of the n+2th transition structure may be an integrated structure.

[0113] As shown in FIG21 , optionally, the conductive bonding member 3320 of the nth transition structure and the conductive bonding member 3320 of the n+1th transition structure are integrally formed. Alternatively, the conductive bonding member of the nth transition structure and the conductive bonding member of the n+1th transition structure may be separate structures, connected by a bridging wire (not shown).

[0114] It is understood that this embodiment is actually a further improvement on the second embodiment, which can at least reduce the occurrence of the first mis-conduction condition mentioned above. When the adapter structure is in the first state, the trigger body and the hole wall are sealed, which can also reduce the occurrence of the second and third mis-conduction conditions.

[0115] While the present invention is disclosed above, it is not limited thereto. Those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, the present invention is intended to encompass such modifications and variations as long as they fall within the scope of the claims and their equivalents.
