[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 unknown, patients with acute myocardial infarction, patients after percutaneous coronary intervention, etc.

[0068] A second object of the present utility model is to provide a temporary pacemaker equipped with the aforementioned electrode lead connection device.

[0069] In order to make the purpose, advantages and features of the utility model clearer, the utility model is further described in detail below in conjunction with the accompanying drawings. It should be noted that the drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the utility model. The same or similar reference numerals in the drawings represent the same or similar components.

[0070] In order to facilitate understanding of the content of the present invention, firstly, 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.

[0071] Please refer to Figure 1 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 arranged on the housing 10, and the connecting device 20 and the electrical component 30 are electrically connected through the wire 40. The electrical component 30 includes a wireless communication module, such as a Bluetooth communication module, a radio frequency communication module, a WIFI module, etc., which plays the role of pacing, sensing, heart rate response, etc., and plays the role of adjusting the operating parameters of the pacemaker during the operation of the temporary pacemaker.

[0072] Please refer to Figure 5 and Fig.15 The standard IS-1 electrode lead includes two electrodes, namely, a first electrode 01 and a second electrode 02. The first electrode 01 and the second electrode 02 are arranged along the axial direction of the standard IS-1 electrode lead, and the first electrode 01 and the second electrode 02 both extend along the axial direction of the standard IS-1 electrode lead, and 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 the temporary pacemaker through the connecting device 20, the first electrode 01 and the second electrode 02 should be electrically connected to the electrical component 30 on the temporary pacemaker through the connecting device 20.

[0073] Please refer to Figure 6 , Figure 7 , Fig.16 and Fig.17 The epicardial temporary pacing electrode lead includes an electrode, which is called the third electrode 04. The third electrode 04 is longer and thinner than the two electrodes of the standard IS-1 electrode lead. When the epicardial temporary pacing electrode lead is connected to the temporary pacemaker through the connecting device 20, the third electrode 04 is electrically connected to the electrical component 30 through the connecting device 20.

[0074] Please refer to Figure 8 and Fig.18 The temporary pacing floating electrode includes an electrode, which is called the fourth electrode 05. The fourth electrode 05 is shorter and thicker than the first electrode 01 of the standard IS-1 electrode lead. When the temporary pacing floating electrode lead is connected to the temporary pacemaker through the connecting device 20, the fourth electrode 05 is electrically connected to the electrical component 30 through the connecting device 20.

[0075] Next, the specific structure of the connection device 20 is described in conjunction with a specific embodiment. It should be noted that the following only describes possible configurations of the connection device 20 in an enumerated manner, but cannot exhaust all optional configurations of the connection device 20, and therefore should not constitute an improper limitation on the present invention.

[0076] <Example 1>

[0077] Figure 2 FIG. 2 shows an exploded schematic diagram of a connecting device 20 provided in this embodiment. Figure 3 and Figure 4 FIG. 2 is a cross-sectional view of another connecting device 20 provided in this embodiment. 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 marked in the figure) 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.

[0078] 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 .

[0079] The connecting device 20 also includes at least one switching structure (not marked in the figure), and the number of the switching structures is set according to needs, for example, Figures 2 to 4 As shown, Figure 2 The number of switching devices in is one, Figure 3 and Figure 4 The number of switching devices in is three. In addition, Figure 2 The cross-sectional view can be referred to Figure 3 and Figure 4 , the only difference is the number of transition structures. Each transition structure includes a through hole 3100, a trigger body (including the conductive trigger body 3210 described later) and a matching body 3300. The through hole 3100 is arranged on the first sleeve 2100 and is connected to the penetration channel. The trigger body is partially arranged in the through hole 3100 and can move in a direction close to or away from the axis of the penetration channel. The matching body 3300 is arranged between the first sleeve 2100 and the second sleeve 2200, and includes a correspondingly arranged conductive elastic member 3310 and a conductive bonding member 3320. The conductive elastic member 3310 is arranged at the through hole 3100 and contacts the trigger body.

[0080] 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, such as Figure 3As shown, 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 the direction away from the axis of the penetration channel, the trigger body is driven to move in the direction away from the axis of the penetration channel, and the trigger body also drives the conductive elastic member 3310 to deform, and makes the conductive elastic member 3310 contact the conductive bonding member 3320, so that the switching structure switches to the second state. It can be understood that in 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 the direction away from the axis of the penetration channel is cancelled, and the conductive elastic member 3310 releases the elastic potential energy, the partial structure of the conductive elastic member 3310 moves in the opposite direction to reset under its own elastic action, and the conductive elastic member 3310 also drives the trigger body to move in the direction close to the penetration channel to reset, so that the switching structure switches back to the first state. The above-mentioned “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.

[0081] In this embodiment, the trigger bodies of all the transfer structures are made of conductive material and are referred to as conductive trigger bodies 3210. Accordingly, at least one window 2210 is provided on the second housing 2200, and at least one window 2210 is provided corresponding to at least one transfer structure, specifically, each window 2210 is provided corresponding to a conductive joint member 3320 of a transfer structure, and each conductive joint member 3320 of the transfer structure can be partially exposed at the corresponding window 2210.

[0082] Please refer back to Figure 1 The wire 40 of the temporary pacemaker includes a first wire 41 and a second wire 42. When the connection device 20 provided in this embodiment is configured to the temporary pacemaker, the conductive block 1000 is connected to the electrical component 30 through the first wire 41, and the conductive joint 3320 of any transition structure is electrically connected to the second wire 42 at the corresponding window 2210, and is electrically connected to the electrical component 30 through the second wire 42.

[0083] When used, the temporary pacemaker equipped with the connection device 20 provided in this embodiment can be adapted to a standard IS-1 electrode lead, an epicardial temporary pacing electrode lead, or a temporary pacing floating electrode lead.

[0084] Specifically, please refer to Figure 5When the temporary pacemaker is adapted to the standard IS-1 electrode lead, the first electrode 01 is inserted into the insulating bushing 2000 along the penetration channel, and contacts with at least one conductive trigger body 3210, and applies a force in the direction away from the axis of the penetration channel to the conductive trigger body 3210 in contact therewith. As a result, at least one conductive trigger body 3210 moves in the direction away from the axis of the penetration channel, so that the corresponding switching structure switches to the second state. Thus, the first electrode 01 of the standard IS-1 electrode lead can be connected to the second lead 42 through the conductive trigger body 3210 in contact therewith and the corresponding matching body 3300, and then electrically connected to the electrical component 30. At the same time, the second electrode 02 of the standard IS-1 electrode lead is located in the conductive block 1000, connected to the conductive block 1000, and can be electrically connected to the electrical component 30 through the conductive block 1000 and the first lead 41.

[0085] Please refer to Figure 6 When the temporary pacemaker is adapted to the epicardial temporary pacing electrode lead, the third electrode 04 is partially inserted into the insulating bushing 2000 along the penetration channel, and is partially located in the conductive block 1000. Ideally, the third electrode 04 is maintained in a straight configuration, and the third electrode 04 is not in contact with the conductive trigger body 3210 of all the switching structures. In this way, the third electrode 04 is only in contact with the conductive block 1000, and can be electrically connected through the conductive block 1000, the first wire 41 and the electrical component 30, so that the temporary pacemaker can be used normally. It should be understood that Figure 7 As shown, when the third electrode 04 is slightly bent so that the third electrode 04 contacts the conductive trigger body 3210 of a part of the transition structure, but the conductive trigger 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 electrically connected to the electrical component 30 through the second wire 42. At this time, the temporary pacemaker can still be used. However, if the third electrode 04 is bent to a greater extent, and at least one conductive trigger body 3210 of the transition structure moves to the point where the corresponding conductive elastic member 3310 contacts the conductive bonding member 3320 under the action of the third electrode 04, the third electrode 04 can be electrically connected to the electrical component 30 through the matching body 3300 and the second wire 42. At this time, the temporary pacemaker cannot be used normally, and the third electrode 04 needs to be pulled out of the insertion channel and re-inserted.

[0086] Please refer to Figure 8 When the temporary pacemaker is adapted to the temporary pacing floating electrode lead, the fourth electrode 05 partially reaches the insulating bushing 2000 along the penetration channel and is partially located in the conductive block 1000, and the free end of the fourth electrode 05 is located on the side of the conductive trigger body 3210 of the transfer structure close to the conductive block 1000. In this way, the fourth electrode 05 is connected to the conductive block 1000 and can be electrically connected to the electrical component 30 through the first wire 41.

[0087] Therefore, when the connecting device 20 provided in this embodiment is applied to a temporary pacemaker, the temporary pacemaker can be suitable for 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 application scope of a single temporary pacemaker.

[0088] Next, various components of the connecting device 20 provided in this embodiment are described in detail.

[0089] Please refer back to Figure 2 , the conductive block 1000 includes a conductive block body 1100 and a fastener 1200. A first channel 1110 extending through the axial direction of the connecting device 20 is provided on the conductive block body 1100, 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. A mounting hole 1120 is also provided on the conductive block body 1100, and the mounting hole 1120 is connected to the first channel 1110. The fastener 1200 is configured to be able to be penetrated at 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 the electrical connection between the electrode and the first lead 41.

[0090] Please refer to Figure 3 and Figure 4 At least one accommodating cavity 2010 is formed between the outer side of the first sleeve 2100 and the inner side of the second sleeve 2200. At least one accommodating cavity 2010 is arranged corresponding to at least one transition structure, and each transition structure is arranged at a corresponding accommodating cavity 2010. Specifically, each through hole 3100 is arranged at a position of the first sleeve 2100 at a corresponding accommodating cavity 2010; each matching body 3300 is at least partially arranged in the corresponding accommodating cavity 2010.

[0091] In this embodiment, in order to facilitate the opening of the accommodating cavity 2010 and the installation of the conductive trigger body 3210 and the matching body 3300, it is preferred that the first housing 2100 and the second housing 2200 are separately processed and then assembled into one body. When not assembled, the second housing 2200 has a second channel 2201 extending through the axial direction thereof, and the second channel 2201 is used to accommodate the first housing 2100. In addition, the first housing 2100 has a third channel 2101 extending through the axial direction thereof, and the third channel 2101 constitutes a part of the through-going channel.

[0092] Optionally, refer to Fig. 9 A first mounting groove 2110 is provided on the outer side of the first housing 2100. Fig.10 As shown, 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 combined to form the accommodating cavity 2010.

[0093] In addition, the through hole 3100 includes a tapered section (not marked in the figure), the tapered section extends in a direction perpendicular to the axis of the through-channel and extends to the inner side surface of the first sleeve 2100, and the cross section of the tapered section gradually decreases in a direction close to the axis of the through-channel. Moreover, the minimum cross section of the tapered section is smaller than the maximum cross section of the conductive trigger body 3210 in a direction perpendicular to the axis of the through-channel 3100. In this way, the hole wall of the tapered section can be used to limit the conductive trigger body 3210 to prevent the conductive trigger body 3210 from escaping from the through-hole 3100 and completely entering the through-channel. 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 in the axial direction perpendicular to the through-channel is smaller than the dimension of the conductive trigger body 3210 in the axial direction perpendicular to the through-channel, so that the conductive trigger body 3210 will not escaping from the through-hole 3100 and completely entering the accommodating cavity 2010.

[0094] The conductive trigger body 3210 may have any suitable shape. In a non-limiting implementation, the conductive trigger body 3210 is a sphere.

[0095] Optionally, return reference Figure 2, the conductive elastic member 3310 may be a sheet-like structure having a first end 3311 and a second end 3312 opposite to each other. In a non-limiting implementation, when the switching structure is in the first state, the first end 3311 of the conductive elastic member and the second end 3312 of the conductive elastic member are opposite to each other in the axial direction of the through-channel. The first end 3311 of the conductive elastic member and the insulating bushing 2000 remain relatively stationary. A portion between the first end 3311 of the conductive elastic member and the second end 3312 of the conductive elastic member contacts the conductive trigger body 3310. The second end 3312 of the conductive elastic member is used to move in a direction close to or away from the axis of the penetration channel. Specifically, when the conductive trigger body 3210 moves in a direction away from the axis of the penetration channel under a force in a direction away from the axis of the penetration channel, 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 penetration channel until the second end 3312 of the conductive elastic member contacts the conductive engagement member 3320 (i.e., the switching structure switches from the first state to the second state). In this process, the conductive elastic member 3310 stores elastic potential energy. When the force acting on the conductive trigger body 3210 in a direction away from the axis of the penetration channel is canceled and the conductive elastic member 3310 releases the elastic potential energy, the second end 3312 of the conductive elastic member moves in a direction close to the axis of the penetration channel until it is reset, and the conductive elastic member 3310 also drives the conductive trigger body 3210 to move in a direction close to the axis of the penetration channel until it is reset (i.e., the switching structure switches from the second state to the first state).

[0096] When assembling the connection device 20, the first end 3311 of the conductive elastic member can be connected to at least one of the first sleeve 2100 and the second sleeve 2200. In addition, the conductive bonding member 3320 can also be a sheet-like structure. When assembling the connection device 20, the conductive bonding member 3320 can be connected to at least one of the first sleeve 2100 and the second sleeve 2200. In an exemplary implementation, the first sleeve 2100 and the second sleeve 2200 can be used to clamp the first end 3311 of the conductive elastic member 3310, and the first sleeve 2100 and the second sleeve 2200 can be used to clamp any suitable position of the conductive bonding member 3320.

[0097] <Example 2>

[0098] Fig.11 FIG. 2 shows an exploded schematic diagram of a connecting device 20 provided in this embodiment. Fig.12 and Fig.13 A cross-sectional view of another connecting device 20 provided in this embodiment is shown. Fig.11 The connecting device 20 shown in FIG. 1 includes a transition structure, Fig.12 and Fig.13The connecting device shown in includes three switching structures. In addition, Fig.11 The cross-sectional view can be referred to Fig.12 and Fig.13 , the only difference is the number of switching structures. Figures 11 to 13 As shown, the difference between this embodiment and the first embodiment lies in the different structure of the conductive elastic member 3310 .

[0099] In detail, the conductive elastic member 3310 includes at least a deformation portion 3313 and a contact portion 3314 connected to each other, and the deformation portion 3313 is configured to be able to extend or shorten in the connection direction between the deformation portion 3313 and the contact portion 3314. The contact portion 3314 includes a guide slope (not marked in the figure), which is inclined relative to the axis of the through hole 3100 and contacts the conductive trigger body 3210.

[0100] In practice, when the switching structure is in the first state, the deformation portion 3313 and the contact portion 3314 are arranged along the axial direction of the through passage. At the same time, the conductive bonding member 3320 is located on the side of the contact portion 3314 away from the deformation portion 3313. In other words, the contact portion 3314 is located on the side of the deformation portion 3313 close to the conductive bonding member 3320.

[0101] When the conductive trigger body 3210 moves in the direction away from the axis of the penetration channel under the force in the direction away from the axis of the penetration channel, the conductive trigger body 3210 applies a force in the direction away from the axis of the penetration channel to the guide slope. Under the action of the guide slope, the contact portion 3314 moves in the direction close to the conductive bonding member 3320, and drives the deformation portion 3313 to stretch and lengthen, thereby making the conductive elastic member 3310 contact the conductive bonding member 3320.

[0102] Alternatively, if Fig.14 As shown, the deformation part 3313 includes a sheet structure, and a plurality of deformation grooves 3315 are provided on the sheet structure, and the extension direction of the deformation grooves 3315 intersects with the connection direction of the contact part 3314 and the deformation part 3313. One end of the deformation groove 3315 is an open end, and the open ends of two adjacent deformation grooves are away from each other. Such a deformation part 3313 has a small volume and can be accommodated in the accommodating cavity 2010. When the contact part 3314 moves in a direction close to the conductive bonding member 3320, the deformation part 3313 is deformed and elongated under the action of the deformation groove. When the force applied to the conductive trigger body 3210 in the axial direction away from the through-channel is cancelled, the deformation part 3313 can return to its original state. In an exemplary implementation, the extension direction of the deformation groove 3315 is perpendicular to the connection direction of the contact part 3314 and the deformation part 3313, and the deformation groove 3315 extends to the edge of the deformation part 3313.

[0103] The connection device 20 provided in this embodiment is applied to a temporary pacemaker and is adapted to a standard IS-1 electrode lead as shown in FIG. Fig.15 As shown. The first electrode 01 is inserted into the insulating bushing 2000 along the penetration channel, and contacts with at least one conductive trigger body 3210, and applies a force in a direction away from the axis of the penetration channel to the conductive trigger body 3210 in contact therewith. As a result, at least one conductive trigger body 3210 moves in a direction away from the axis of the penetration channel, so that the contact portion 3314 of the corresponding conductive elastic member 3310 moves in a direction away from the deformation portion 3313, so that the deformation portion 3313 stretches and lengthens until it contacts with the conductive bonding member 3320.

[0104] Please refer to Fig.16 When the temporary pacemaker is adapted to the epicardial temporary pacing electrode lead, the third electrode 04 is partially inserted into the insulating bushing 2000 along the penetration channel, and is partially located in the conductive block 1000. Ideally, the third electrode 04 is kept in a straight configuration, and the third electrode 04 does not contact the conductive trigger body 3210 of all the switching structures. In this way, the third electrode 04 only contacts the conductive block 1000, and is connected to the electrical component 30 through the conductive block 1000 and the first lead 41, so that the temporary pacemaker can be used normally. Fig.17 As shown, in some cases, the third electrode 04 inserted into the insulating bushing 2000 is in a bent state. If the third electrode 04 is slightly bent so that the third electrode 04 contacts the conductive trigger body 3210 of a part of the transition structure, but the conductive trigger body 3210 does not move to make the corresponding conductive elastic member 3310 contact the conductive bonding member 3320, the third electrode 04 is not connected to the electrical component 30 through the second wire 42, and the temporary pacemaker can still be used. However, if the third electrode 04 is bent to a large extent, and at least one conductive trigger body 3210 of the transition structure moves to the corresponding conductive elastic member 3310 contact the conductive bonding member 3320 under the action of the third electrode 04, the third electrode 04 is connected to the electrical component 30 through the matching body 3300 and the second wire 42. At this time, the temporary pacemaker cannot be used normally, and the third electrode 04 needs to be pulled out of the penetration channel and re-inserted.

[0105] Please refer to Fig.18 When the temporary pacemaker is adapted to the temporary pacing floating electrode lead, the fourth electrode 05 partially reaches the insulating bushing 2000 along the penetration channel and is partially located in the conductive block 1000, and the free end of the fourth electrode 05 is located on the side of the conductive trigger body 3210 of the transfer structure close to the conductive block 1000. In this way, the fourth electrode 05 is connected to the conductive block 1000 and is connected to the electrical component 30 through the first wire 41.

[0106] <Example 3>

[0107] This embodiment is a further improvement on the first embodiment, and can avoid the situation where the third electrode 04 or the fourth electrode 05 is misconnected with the electrical component 30 when the temporary pacemaker is adapted to the epicardial temporary pacing electrode lead and the temporary pacing floating electrode lead.

[0108] For ease of distinction, in the description of this embodiment, the temporary pacemaker configured with the connecting device 20 provided in Embodiment 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.

[0109] In addition, to facilitate understanding of the present embodiment, the misconduction between 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 between 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.

[0110] For the case where the first temporary pacemaker is adapted to the epicardial temporary pacing electrode lead, there are two mis-conduction situations, among which the first mis-conduction situation is when the third electrode 04 is in a bent state after being inserted into the insulating bushing 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 part of the structure of the conductive elastic member 3310 to move until the conductive elastic member 3310 is connected to the conductive coupling member 3320, so that the third electrode 04 is connected to the electrical component 30 through at least part of the conductive trigger body 3210, the corresponding matching body 3300 and the second wire 42. The second misconduction situation is that even if the third electrode 04 remains in a straight configuration or has a small bending range after being inserted into the insulating bushing 2000, when the third electrode 04 carries a large amount of conductive liquid into the insulating bushing 2000, the conductive liquid may flow into the through hole 3100 and the accommodating cavity 2010, causing the third electrode 04 to be electrically connected to the conductive trigger body 3210 and the matching body 3300 through the conductive liquid. The conductive liquid is, for example, physiological saline, blood, etc.

[0111] For the case where the first temporary pacemaker is adapted to the temporary pacing floating electrode, there is a misconnection situation, which is called the third misconnection situation. The third misconnection situation is that the fourth electrode 05 carries a lot of conductive liquid during the insertion of the insulating bushing 2000, and the conductive liquid may flow into the through hole 3100 and the accommodating cavity 2010, causing the fourth electrode 05 to be electrically connected with the conductive trigger body 3210 and the matching body 3300 through the conductive liquid.

[0112] Next, the structure of the connecting device 20 provided in this embodiment is introduced.

[0113] Fig.19FIG. 2 shows an exploded schematic diagram of the connection device 20 provided in this embodiment. Fig. 20 and Fig.21 is a cross-sectional view of the connecting device 20. Figures 19 to 21 As shown, in this embodiment, the connection device 20 includes a plurality of transfer structures, a part of the plurality of transfer structures is a first transfer structure, and another part is a second transfer structure, the trigger body of the first transfer structure is a conductive trigger body 3210, and the trigger body of the second transfer structure is an insulating trigger body 3220 made of insulating material. In addition, only one window 2210 is provided on the second sleeve 2200, and the window 2210 is provided corresponding to a conductive joint 3320 of a second transfer structure, so that the conductive joint 3320 of the second transfer structure is exposed at the window 2210 and is electrically connected to the electrical component 30 through the second wire 42. In addition, when all the transfer structures are in the second state, the conductive elastic members 3310 and the conductive joint 3320 of all the transfer structures are connected in series. In this way, at least the occurrence of the first type of misconnection can be avoided. The specific principle will be described in detail later.

[0114] Alternatively, if Fig. 20 and Fig.21 As shown, all the transfer structures are arranged at intervals along the circumference of the penetration channel, and the number of the first transfer structure is one. All the transfer structures are numbered along the circumference of the penetration channel, and the first transfer structure is taken as the first transfer structure. The conductive bonding member 3320 of the nth transfer structure is connected to the conductive bonding member 3320 of the n+1th transfer structure, and the conductive elastic member 3310 of the n+1th transfer structure is connected to the conductive elastic member 3310 of the n+2th transfer structure. The window 2210 is arranged corresponding to the conductive bonding member 3320 of the last second transfer structure, so that the conductive bonding member 3320 of the last second transfer 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.

[0115] In an exemplary implementation, the number of transition structures is three, namely, a 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 disposed at the conductive bonding member 3320 of the second second transition structure, so 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.

[0116] When the connecting device 20 provided in this embodiment is applied to the second temporary pacemaker, and the second temporary pacemaker is adapted to the standard IS-1 electrode wire, the first electrode 01 of the standard IS-1 electrode wire 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 trigger bodies of the three adapter structures, so that the trigger 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 sequentially connected in series and are electrically connected to the electrical component 30 via the second wire 42.

[0117] When the second temporary pacemaker is adapted to the epicardial temporary pacing electrode lead, the third electrode 04 is inserted into the insulating bushing 200 through the penetration channel. Even if the third electrode 04 is bent and part of the switching structure is switched from the first state to the second state, for example, the first switching structure and the first second switching structure are switched to the second state, but because the second second switching structure is not switched to the second state, that is, the conductive elastic member 3310 and the conductive bonding member 3320 of the second second switching structure are disconnected, the third electrode 04 cannot be electrically connected to the second lead 42. Similarly, when the third electrode 04 is bent so that the first switching structure and the second second switching structure are switched to the second state, or the two second switching structures are switched to the second state, the third electrode 04 cannot be electrically connected to the second lead 42.

[0118] In this embodiment, if Fig.19 As shown, the conductive bonding member 3320 of the nth transition structure and the conductive bonding member 3320 of the n+1th transition structure are an integrated structure. Figures 19 to 21 In the implementation shown (i.e., there are three transfer structures, one of which is the first transfer structure and the other two are the second transfer structures), the conductive bonding member 3320 of the first transfer structure and the conductive bonding member 3320 of the first second transfer structure are an integrated structure. Of course, in an alternative implementation, the conductive bonding member of the nth transfer structure and the conductive bonding member of the n+1th transfer structure may also be a split structure, and the two are connected by a bridge wire (not shown in the figure), which will not be described here.

[0119] like Fig.19As shown, optionally, the conductive elastic member 3310 of the n+1th transition structure and the conductive elastic member 3310 of the n+2th transition structure are an integrated structure. Figures 19 to 21 In the implementation shown, the conductive elastic member 3310 of the first second transition structure and the conductive elastic member 3310 of the second second transition structure are an integrated structure. Alternatively, the conductive elastic member of the n+1th transition structure and the conductive elastic member of the n+2th transition structure may also be a split structure, and the two are connected by a bridge wire (not shown in the figure), which will not be described here.

[0120] Further preferably, in this embodiment, when the switching structure is in the first state, each trigger body is sealed with the hole wall of the corresponding through hole 3100. In this way, the situation where the charged liquid flows into the through hole 3100 can be reduced, thereby reducing the occurrence of the second misconduction situation and the third misconduction situation.

[0121] 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 preventing the conductive liquid brought into the penetration channel by the third electrode 04 or the fourth electrode 05 from easily entering the through hole 3100.

[0122] This embodiment has no special limitation on the formation of the accommodating cavity 2010, as long as the formed accommodating cavity 2010 matches the structure and position of the transfer structure, so that the through hole 3100 of the transfer structure can be arranged in the area where the first sleeve 2100 is located in the corresponding accommodating cavity 2010, and the matching body 3300 is located in the corresponding accommodating cavity 2010. In a specific implementation, at least two first installation grooves 2110 are provided on the outer side of the first sleeve 2100, and at least two second installation grooves 2220 are provided on the inner side of the second sleeve 2200. Figures 19 to 21As shown in the example, two first mounting grooves 2110 are provided on the outer surface of the first sleeve 2100, and two second mounting grooves 2220 are provided on the second sleeve 2200. 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 part of the second mounting groove a to form an accommodating cavity 2010, a part of the first mounting groove b cooperates with another part of the second mounting groove a to form another accommodating cavity 2010, and another part of the first mounting groove b is arranged with the second mounting groove b to form another accommodating 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 part of the structure of the conductive joint 3320 is clamped and fixed by the first sleeve 2100 and the second sleeve 2200, a sealant may be coated on the surface of the clamped part of the conductive joint 3320 to enhance the sealing between the conductive joint 3320 and the first sleeve 2100 and the second sleeve 2200. The advantage of this 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 matching body 3300 being electrically connected to the electrode through the conductive liquid.

[0123] 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 in detail here.

[0124] <Example 4>

[0125] Fig. 22 FIG. 2 shows an exploded schematic diagram of the connection device 20 provided in this embodiment. Fig.23 and Fig.24 FIG. 2 is a cross-sectional view of the connection device 20 of this embodiment. Figure 22 to Figure 24 The difference between the connection device 20 of this embodiment and the connection device 20 of the third embodiment is that the configuration of the conductive elastic member 3310 is different.

[0126] The specific configuration of the conductive elastic member 3310 in this embodiment can be referred to in the second embodiment and will not be described in detail here.

[0127] In addition, in this embodiment, Fig.21 As shown, 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 a split structure, and the two are connected by a bridge wire 3330.
