Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to a temporary pacemaker electrode catheter adapter. Background Technology

[0002] A temporary pacemaker is a cardiac pacing device for short-term use. However, in clinical practice, some patients may require prolonged reliance on this device. For example, a certain percentage of patients with acute cardiac conditions (such as acute myocardial infarction and fulminant myocarditis) and those undergoing cardiac surgery experience severe bradycardia and require a temporary pacemaker to maintain stable vital signs. In some of these patients, the time for spontaneous heart rhythm recovery may be as long as 2 to 4 weeks. Furthermore, there are also patients who require prolonged reliance on a temporary pacemaker due to the lack of suitable conditions for permanent pacemaker implantation (such as severe infection or a high risk of bleeding).

[0003] Temporary pacemakers, due to their larger size and the need for regular battery replacements, may restrict patients' daily activities. Furthermore, prolonged use of temporary pacemakers can lead to battery depletion or device malfunction, increasing the risk of cardiac arrest. It is important to note that the number of temporary pacemakers is limited, primarily used for emergency or transitional treatment of bradycardias and for functional testing during permanent pacemaker surgery. If multiple patients require temporary pacemakers simultaneously, it can further strain medical resources and even prevent patients from receiving timely treatment.

[0004] Currently, with the aging population and the increasing number of implanted permanent pacemakers, the need to replace permanent pacemakers (i.e., pulse generators) due to near-depletion of the battery or changes in the patient's condition is growing. It is worth noting that these fully functional permanent pacemakers removed from patients typically retain a certain amount of charge in their batteries (the remaining battery life and estimated usable time can be accurately assessed through pacemaker programming), thus theoretically allowing them to be reused as temporary external pacemakers. Furthermore, the compact and lightweight nature of permanent pacemakers significantly improves patient comfort.

[0005] However, current temporary pacing electrode catheters are not compatible with permanent pacemaker interfaces, so there is an urgent need to develop a conversion connector for temporary pacing electrode catheters. Utility Model Content

[0006] The technical problem to be solved by this utility model is to address the above-mentioned defects in the prior art by providing a temporary pacemaker electrode catheter adapter that can achieve compatibility between temporary pacemaker electrode catheters and permanent pacemaker interfaces.

[0007] According to this utility model, a temporary pacemaker electrode catheter adapter is provided, comprising: an adapter module and a permanent pacemaker cable;

[0008] The connector module has a first connector pin insertion port and a second connector pin insertion port for temporary pacemaker electrode catheters on the side opposite to the permanent pacemaker cable. The first connector pin insertion port includes an anode spring made of conductive material, and the second connector pin insertion port includes a cathode spring made of conductive material. The anode spring and the cathode spring are electrically connected to the anode wire and the cathode wire, respectively.

[0009] Furthermore, the anode and cathode leads extend from the connector module into the permanent pacemaker cable, and the cable ends at the end of the leads that are opposite to the connector module are electrically connected to the annular anode electrode and the rod-shaped cathode electrode, respectively, and the cable ends are used to insert the permanent pacemaker.

[0010] Thus, when the connector pins of the temporary pacemaker electrode catheter are inserted into the first connector pin insertion port and the second connector pin insertion port respectively, and the cable tail end is inserted into the permanent pacemaker, a stable electrical connection is achieved between the temporary pacemaker electrode catheter and the permanent pacemaker.

[0011] Preferably, the connector module includes fastening devices respectively arranged on the sides of the anode and cathode springs. The fastening devices include a thumbwheel and a helical rotating rod screwed into the thumbwheel. Rotating the thumbwheel drives the helical rotating rod to move up and down, thereby controlling the pressing and releasing of the connector needle by the helical rotating rod. This achieves a secure connection and separation between the temporary pacemaker electrode catheter and the connector module. The helical rotating rod is connected to the housing of the connector module via a helical structure. When the helical rotating rod is in close contact with and fixed to the connector needle, a sealed connection is formed between the thumbwheel, the helical rotating rod, and the connector module.

[0012] More preferably, the spiral rotating rod and the spiral structure within the connector module housing are made of conductive material, and the spiral structure within the connector module housing is electrically connected to the anode wire and the cathode wire respectively via wires. Therefore, when the spiral rotating rod abuts against and secures the connector pin of the temporary pacemaker electrode catheter, a reliable electrical connection can be further ensured between the temporary pacemaker electrode catheter and the permanent pacemaker cable.

[0013] Preferably, the insulation material combines flexibility and bending resistance. The insulation extends toward the end of the permanent pacemaker cable and connects to an insulating cap located away from the end of the permanent pacemaker cable.

[0014] Preferably, an insulating sealing structure comprising an insulating cap and a sealing ring is arranged in the region near the end of the permanent pacemaker cable, wherein the sealing ring surrounds the outside of the insulating cap and the inner diameter of the sealing ring matches the permanent pacemaker electrode socket.

[0015] More preferably, there are two insulating sealing structures; the insulating sealing structure near the end of the permanent pacemaker cable is used to isolate the annular anode electrode and the rod-shaped cathode electrode to prevent short circuits; the insulating sealing structure away from the end of the permanent pacemaker cable is used to seal and prevent external humid air from entering the electrode socket, thus avoiding the risk of short circuits caused by moisture.

[0016] Preferably, the permanent pacemaker cable is equipped with a loop-shaped insulating fastener for securely bonding the insulating material to the internal electrodes.

[0017] Preferably, the permanent pacemaker cable is equipped with an insulating connector made of insulating material for connecting and securing the annular anode electrode and the rod-shaped cathode electrode.

[0018] Preferably, the annular anode electrode is made of a conductive material with a hollow tubular structure, and the interior of the annular anode electrode is filled with insulating material. The portion of the annular anode electrode away from the end of the permanent pacemaker cable forms a support structure together with the outer insulation layer, facilitating handheld operation and pushing or pulling the end of the permanent pacemaker cable into or out of the permanent pacemaker socket. The portion of the outer surface area of ​​the annular anode electrode near the end of the permanent pacemaker cable, located between the insulating connector and the insulating cap away from the end of the permanent pacemaker cable, is exposed outside the outer insulation layer, enabling electrical contact with the annular anode junction area of ​​the permanent pacemaker, and achieving effective electrical communication with the permanent pacemaker through the internally connected anode wire.

[0019] Preferably, the cathode lead passes through the insulation layer inside the annular anode electrode and is electrically connected to the rod-shaped cathode electrode inside the insulating connector. When the rod-shaped cathode electrode is fully inserted into the permanent pacemaker's socket and the fixing screws on the permanent pacemaker are tightened, a stable and reliable electrical connection is ensured between the rod-shaped cathode electrode and the permanent pacemaker.

[0020] Preferably, the permanent pacemaker cable is equipped with a protective sheath installed around the outer insulation layer of the annular anode electrode away from the end of the permanent pacemaker cable. This sheath protects the outer insulation layer at the installation site and limits its bending. This reduces shear stress between the insulation layer and the inner annular anode electrode port caused by bending. Furthermore, the protective sheath also positions the handheld operating part closer to the end of the permanent pacemaker cable.

[0021] Preferably, the temporary pacemaker electrode catheter adapter also includes a temporary pacemaker cable for electrical connection to the temporary pacemaker.

[0022] Therefore, this invention proposes a temporary pacemaker electrode catheter adapter that enables compatibility between temporary pacing electrode catheters and permanent pacemaker interfaces. This design not only makes full use of a fully functional permanent pacemaker with a certain amount of charge, but also meets the clinical needs of patients who rely on temporary cardiac pacing therapy for a long period of time.

[0053] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0055] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0056] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0057] Figure 1 A schematic diagram of the structure of a temporary pacemaker electrode catheter adapter 1000 according to a preferred embodiment of the present invention is shown.

[0058] like Figure 1 As shown, the temporary pacemaker electrode catheter adapter 1000 according to a preferred embodiment of the present invention includes: a connector module 100 and a permanent pacemaker cable 200 connected to each other.

[0059] The connector module 100 has a first connector pin insertion port 101 and a second connector pin insertion port 102 for a temporary pacemaker electrode catheter 500 on the side opposite to the permanent pacemaker cable 200. The first connector pin insertion port 101 includes an anode spring 103 made of conductive material, and the second connector pin insertion port 102 includes a cathode spring 104 made of conductive material. The anode spring 103 and the cathode spring 104 are electrically connected to the anode wire 105 and the cathode wire 106, respectively.

[0060] Furthermore, the anode lead 105 and the cathode lead 106 extend from the connector module 100 into the permanent pacemaker cable 200, and the cable tail 201 at the end of the permanent pacemaker cable 200 opposite to the connector module 100 is electrically connected to the annular anode electrode 206 and the rod-shaped cathode electrode 207, respectively. The cable tail 201 is used to insert into the permanent pacemaker 410 (e.g., the atrial electrode socket or ventricular electrode socket of the permanent pacemaker 410).

[0061] Therefore, when the connector pin 300 of the temporary pacemaker electrode catheter 500 is inserted into the first connector pin insertion port 101 and the second connector pin insertion port 102 respectively (for example, as...), Figure 2As shown, when the two connector pins 300 of the temporary pacemaker electrode catheter 500 are inserted into the first connector pin insertion port 101 and the second connector pin insertion port 102 respectively, and the cable tail end 201 is inserted into the permanent pacemaker 410, an electrical connection can be achieved between the temporary pacemaker electrode catheter 500 and the permanent pacemaker 410. This ensures effective signal transmission.

[0062] Preferably, such as Figure 1 As shown, the connector module 100 includes fastening devices respectively arranged on the sides of the anode spring 103 and the cathode spring 104. The fastening devices include a thumbwheel 107 and a helical rotating rod 108 screwed into the thumbwheel. Rotating the thumbwheel 107 drives the helical rotating rod 108 to move up and down, thereby controlling the pressing and releasing of the connector needle 300 by the helical rotating rod 108. This achieves a secure connection and separation between the temporary pacemaker electrode catheter 500 and the connector module 100. The helical rotating rod 108 is connected to the housing of the connector module 100 via a helical structure (i.e., the helical rotating rod 108 screws into the housing of the connector module 100). When the helical rotating rod 108 is in close contact with and fixed to the connector needle 300, a sealed or near-sealed connection can be formed between the thumbwheel 107, the helical rotating rod 108, and the connector module 100.

[0063] More preferably, the spiral rotating rod 108 and the spiral structure inside the connector module 100 housing are made of conductive material, and the spiral structure inside the connector module 100 housing is electrically connected to the anode wire 105 and the cathode wire 106 respectively through wires. Therefore, when the spiral rotating rod 108 abuts against and fixes the connector pin 300 of the temporary pacemaker electrode catheter 500, a reliable electrical connection can be further ensured between the temporary pacemaker electrode catheter 500 and the permanent pacemaker cable 200.

[0064] Preferably, an insulating layer 202 is arranged between the anode conductor 105 and the cathode conductor 106, and on the outside of the anode conductor 105 and the cathode conductor 106. The insulating layer 202 protects the anode conductor 105 and the cathode conductor 106 from contact that could cause a short circuit. Its material combines flexibility and bending resistance. The insulating layer 202 extends toward the end 201 of the permanent pacemaker cable and connects to an insulating cap located away from the end 201 of the permanent pacemaker cable.

[0065] Preferably, an insulating sealing structure 203, including an insulating cap and a sealing ring, is arranged in the region of the permanent pacemaker cable 200 near the cable tail 201, wherein the sealing ring surrounds the outside of the insulating cap and the inner diameter of the sealing ring matches the electrode socket of the permanent pacemaker 410.

[0066] More preferably, there are two insulating sealing structures 203. The insulating sealing structure 203 near the end 201 of the permanent pacemaker cable is used to isolate the annular anode electrode 206 and the rod-shaped cathode electrode 207 to prevent short circuits; while the insulating sealing structure 203 away from the end 201 of the permanent pacemaker cable is used to seal and prevent external humid air from entering the electrode socket, avoiding the risk of short circuits caused by moisture.

[0067] Preferably, the permanent pacemaker cable 200 is provided with an insulating fastener 204 in a ring shape for securely bonding the insulating material to the internal electrodes.

[0068] Preferably, the permanent pacemaker cable 200 is provided with an insulating connector 205 made of insulating material for connecting and securing the annular anode electrode 206 and the rod-shaped cathode electrode 207. The insulating connector 205 is further preferably made of a high-strength insulating material.

[0069] The annular anode electrode 206 is made of a conductive material with a hollow tubular structure. The interior of the annular anode electrode 206 is filled with insulating material, and the exterior of the annular anode electrode 206 is wrapped with an insulating material that has both wear resistance and corrosion resistance. The portion of the annular anode electrode 206 away from the permanent pacemaker cable end 201 forms a support structure together with the outer insulation layer 202, which facilitates hand operation and allows the permanent pacemaker cable end 201 to be pushed into or pulled out of the socket of the permanent pacemaker 410. The portion of the annular anode electrode 206 near the outer surface area of ​​the permanent pacemaker cable end 201, located between the insulating connector 205 and the insulating cap away from the permanent pacemaker cable end 201, is exposed outside the outer insulation layer 202 and can make electrical contact with the annular anode junction area of ​​the permanent pacemaker 410. It can also achieve effective electrical communication with the permanent pacemaker 410 through the internally connected anode wire.

[0070] The cathode lead 106 passes through the insulation layer 202 inside the annular anode electrode 206 and is tightly connected to the rod-shaped cathode electrode 207 inside the insulating connector 205. When the rod-shaped cathode electrode 207 is fully inserted into the socket of the permanent pacemaker 410 and the fixing screw on the permanent pacemaker 410 is tightened, a stable and reliable electrical connection can be established between the rod-shaped cathode electrode 207 and the permanent pacemaker 410.

[0071] Preferably, the permanent pacemaker cable 200 is equipped with a protective sheath 208, installed around the outer insulation layer 202 of the annular anode electrode 206 away from the end 201 of the permanent pacemaker cable, to protect the outer insulation layer 202 at the installation site and limit its bending. This reduces the shear stress between the insulation layer 202 and the port of the inner annular anode electrode 206 caused by bending. Furthermore, the protective sheath 208 also serves to position the handheld operating part on the side near the end 201 of the permanent pacemaker cable.

[0072] Specifically, in temporary pacemaker implantation, the procedure involves, for example, the following methods: Figure 1 The temporary pacemaker electrode catheter adapter 1000 shown is used to preset and adjust the parameters of the permanent pacemaker 410 using a programmer compatible with the permanent pacemaker 410, according to the patient's condition, to understand the function of the permanent pacemaker 410, battery power, and set pacing parameters. Depending on the intended pacing chamber, the tail end 201 of the permanent pacemaker cable is fully inserted into the atrial or ventricular electrode socket of the permanent pacemaker 410, and the screws securing the permanent pacemaker 410 are tightened using the included screwdriver until a continuous confirmation beep is heard. Then, the thumbwheels 107 on both sides of the front end of the adapter module 100 are fully opened. Depending on the polarity of the temporary pacemaker electrode catheter 500 connector pins 300 (generally, black is the cathode and red is the anode), the connector pins 300 are fully inserted into the corresponding ports of the adapter module 100. The thumbwheels 107 are then tightened to ensure the connector pins 300 are securely fixed. Figure 2 As shown. The insertion of the temporary pacing electrode catheter 500 follows standard surgical procedures, with the pacing position determined by surface electrocardiogram or intracardiac electrocardiogram displayed on the programmer. After confirming stable pacing signal, the parameters of the permanent pacemaker 410 are programmed again using the programmer. Finally, the temporary pacing electrode catheter 500 is properly secured, and the external temporary pacemaker electrode catheter adapter 1000 and the permanent pacemaker 410 are properly positioned.

[0073] like Figure 2 As shown, for example, the permanent pacemaker cable 200 is connected to the permanent pacemaker 410 (i.e., the pulse generator); the connector pin 300 of the temporary pacemaker electrode catheter 500 with a balloon is fully inserted into the port of the corresponding connector module 100. This design enables the reuse of the permanent pacemaker 410, effectively avoiding the risk of cardiac arrest caused by prolonged continuous use of the temporary pacemaker, such as battery depletion, electrical signal interruption during battery replacement, and potential functional malfunctions. Furthermore, both the temporary pacemaker electrode catheter adapter 1000 and the permanent pacemaker 410 are compact and lightweight, thus reducing the impact on the patient's daily activities.

[0074] Figure 3A schematic diagram of the structure of a temporary pacemaker electrode catheter adapter 1000 according to another preferred embodiment of the present invention is shown.

[0075] and Figure 2 The difference in the structure shown is that the temporary pacemaker electrode catheter adapter 1000 also includes a temporary pacemaker cable 400 for electrical connection with the temporary pacemaker. This design allows for flexible switching between the temporary pacemaker and the permanent pacemaker 410 without interrupting the electrical signal connection between the temporary pacemaker electrode catheter 500 and the pacemaker.

[0076] In clinical practice, although temporary pacemakers are relatively large and limited in number, they are easy to operate. Therefore, temporary pacemakers can be preferentially connected during surgery. This is especially important when the pacing signal is stable and the patient is expected to require prolonged pacing therapy (e.g., when...). Figure 3 As shown, another form of the temporary pacemaker electrode catheter adapter 1000 in this embodiment can be used, including a temporary pacemaker cable 400 and a permanent pacemaker cable 200. The wires in the adapter module 100 do not intersect; the cables are divided into a temporary pacemaker cable 400 and a permanent pacemaker cable 200. During the procedure, a conventional temporary pacemaker can be connected via the temporary pacemaker cable 400, and the temporary pacemaker electrode catheter 500 can be connected via the adapter module 100. Postoperatively, the parameters of the permanent pacemaker 410 are programmed according to the patient's condition, with the pacing rate of the permanent pacemaker 410 preset to be approximately 10 beats / min lower than the pacing rate set on the temporary pacemaker. Depending on the pacing chamber, the tail end 201 of the permanent pacemaker cable is fully inserted into the atrial or ventricular electrode socket of the permanent pacemaker 410, and the screws securing the permanent pacemaker 410 are tightened using a matching screwdriver until a continuous confirmation beep is heard. The pacing frequency of the programmed permanent pacemaker 410 is adjusted from a higher setting than the temporary pacemaker to a frequency at which the pacing chamber can be fully captured. After the pacing signal stabilizes, the parameters of the permanent pacemaker 410 are reprogrammed. Finally, the connection between the temporary pacemaker cable 400 and the conventional temporary pacemaker is disconnected, and the pacing frequency of the permanent pacemaker 410 is reprogrammed to an appropriate level. Finally, the external temporary pacemaker electrode catheter adapter 1000 and the permanent pacemaker 410 are properly positioned. Furthermore, it can be noted that, as shown by the dashed circle 600, the wires here do not intersect and are separated by an insulating layer.

[0077] It should be noted that the interface design for the temporary pacemaker cable 400 to connect with the conventional temporary pacemaker is consistent with that of the conventional temporary pacemaker cable interface, and will not be described again.

[0078] Therefore, this utility model provides a temporary pacemaker electrode catheter adapter that enables compatibility between temporary pacing electrode catheters and permanent pacemaker interfaces. Furthermore, it should be noted that, unless otherwise specified, the terms "first," "second," "third," etc., used in this specification are merely for distinguishing individual components, elements, and steps within the specification, and are not intended to indicate logical or sequential relationships between them.

[0079] It is understood that although the present invention has been disclosed above with reference to preferred embodiments, these embodiments are not intended to limit the present invention. For any person skilled in the art, many possible variations and modifications can be made to the present invention without departing from the scope of the present invention, or equivalent embodiments can be modified based on the disclosed technical content. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
