Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to an external temporary pacemaker fixation device. Background Technology

[0002] Temporary pacemaker implantation is widely used for the temporary rescue or preventive treatment of severe bradyarrhythmias (such as complete atrioventricular block, second-degree type II atrioventricular block, etc.), tachyarrhythmias unresponsive to or unsuitable for drug therapy or electrical cardioversion (overspeed suppression), QT interval prolongation complicated by torsades de pointes, and improving the tolerance and safety of anesthesia and surgery in patients with bradyarrhythmias. It can be administered via different electrical stimulation pathways, including transvenous pacing (preferred), percutaneous pacing, transthoracic pacing, transesophageal pacing, and postoperative epicardial pacing. The pulse generator is placed externally and can be removed after the therapeutic or diagnostic purpose is achieved; it is generally left in place for 1-7 days.

[0003] However, there are currently many problems with temporary pacemaker implantation. The most common issues after implantation are lead dislodgement, displacement, and disconnection. Regarding fixation methods, pacemakers via the femoral vein approach are often secured to the thigh with tape or specific fixators, causing significant patient discomfort and potentially leading to local pain, pressure sores, and tape allergies. Temporary pacemakers via the jugular vein approach or epicardial pacing lack suitable fixation positions and / or devices, and are usually suspended or placed directly on the bed, resulting in a high risk of lead dislodgement. Furthermore, the pulse generator is often in a bare state, making it prone to accidental activation or electrode dislodgement, which can affect pacing performance.

[0004] Therefore, it is necessary to make further improvements to the existing technology. Utility Model Content

[0090] The external temporary pacemaker 60 fixation device of this utility model embodiment is described in detail below with reference to the accompanying drawings.

[0091] Reference Figures 1 to 12 As shown, an external temporary pacemaker 60 fixation device provided according to an embodiment of the present utility model includes a placement plate 10, a clamping assembly 20, a cable management assembly 30, and a fixing strap 40.

[0092] The placement plate 10 is used to place the pacemaker 60. The placement plate 10 can be made of acrylic sheet to make it lighter and reduce the burden on the patient.

[0093] The clamping assembly 20 includes a first clamping member 21 and a second clamping member 22. The first clamping member 21 and the second clamping member 22 are respectively disposed on the left and right sides of the placement plate 10, and one end is inserted into the placement plate 10 to form a linkage, so that the first clamping member 21 and the second clamping member 22 can move synchronously in the mirror direction along the width of the placement plate 10 to clamp the pacemaker 60 placed on the placement plate 10.

[0094] The cable management assembly 30 is located at the tail end of the placement plate 10 and is used to fix the connecting wires of the pacemaker 60 as a whole.

[0095] The fixing strap 40 is connected to the middle of the bottom surface of the placement plate 10 to fix the placement plate 10 to the patient's limb.

[0096] Based on the above, the first clamping member 21 and the second clamping member 22, located on the left and right sides of the placement plate 10, are linked together by inserting one end into the placement plate 10. They can move synchronously and mirror-image along the width of the placement plate 10, effectively clamping the pacemaker 60 placed on the placement plate 10, ensuring the stability of the pacemaker 60 and reducing the risk of shaking or displacement. The cable management assembly 30 is located at the tail end of the placement plate 10, which can fix the connecting wires of the pacemaker 60 as a whole, avoiding messy connections and preventing tangling and knotting, facilitating operation by medical staff, and reducing the probability of accidents caused by connection problems. The fixing strap 40 can fix the entire fixing device and the pacemaker 60 together to the patient's limb. The fixing method is comfortable and reliable, avoiding the sequelae caused by tape fixing. This utility model has a simple structure, combining convenience and safety, and reducing the risks during use.

[0097] Preferably, in one embodiment of the present invention, the placement plate 10 includes a lower plate body 11 and an upper plate body 12.

[0098] The upper surface of the lower plate 11 is provided with two mounting grooves 111, which are spaced apart along the length of the lower plate 11. A first slot 112 is provided on one side of each mounting groove 111, which extends to one outer side of the lower plate 11. A second slot 113 is provided on the other side of each mounting groove 111, which extends to the other outer side of the lower plate 11.

[0099] The upper plate 12 is detachably disposed on the upper surface of the lower plate 11 to enclose the mounting groove 111.

[0100] Wherein, the ends of the first clamping member 21 extend from the two first slots 112 into the two mounting slots 111 respectively, and the ends of the second clamping member 22 extend from the second slot 113 into the mounting slot 111, and the ends of the first clamping member 21 and the second clamping member 22 are connected in the mounting slot 111.

[0101] Thus, the placement plate 10 adopts a detachable design for the lower plate 11 and the upper plate 12, facilitating the installation, inspection, and maintenance of the internal structure. When it is necessary to handle the clamping assembly 20 or other internal components, only the upper plate 12 needs to be removed, eliminating the need for complex disassembly of the entire device, thereby improving operational efficiency and reducing maintenance costs. By providing a dedicated mounting slot 111 on the lower plate 11 to accommodate the connection part of the clamping assembly 20, the internal structure of the entire placement plate 10 becomes more compact, reducing unnecessary space occupation. This also helps to improve the overall structural stability of the device, ensuring that all components can operate normally and reliably during the use of the pacemaker 60.

[0102] Preferably, in one embodiment of the present invention, the first clamping member 21 in the placement plate 10 includes two first driving arms 211 and one first connecting arm 212. The first connecting arm 212 is disposed on the outside of the placement plate 10 and connected to one end of the two first driving arms 211. The other ends of the two first driving arms 211 are respectively inserted into the mounting groove 111 by the two first slots 112.

[0103] The second clamping member 22 includes two second driving arms 221 and one second connecting arm 222. The second connecting arm 222 is located on the outside of the placement plate 10 and is connected to one end of the two second driving arms 221. The other ends of the two second driving arms 221 are respectively inserted into the mounting groove 111 through the two second slots 113.

[0104] The two ends of the first drive arm 211 and the second drive arm 221 are connected to each other and form a linkage structure that can move in a mirror image.

[0105] Thus, the first clamping member 21 and the second clamping member 22, through their respective drive arms and connecting arms, and with one end of the two first drive arms 211 and the second drive arms 221 connected to each other within the mounting groove 111, form a mirror-movable linkage structure. This ensures that the first clamping member 21 and the second clamping member 22 can perform mirror-movement synchronously and stably, achieving precise clamping of the pacemaker 60, effectively avoiding asynchronous or unstable situations during clamping, and improving the reliability and stability of clamping. The first clamping member 21 uses two first drive arms 211 and one first connecting arm 212, and the second clamping member 22 uses two second drive arms 221 and one second connecting arm 222, resulting in a simple and clear structure. This simple structure not only facilitates manufacturing and assembly, reducing production costs, but also reduces potential failure points due to structural complexity, improving the overall reliability and service life of the device.

[0106] As a preferred embodiment of the present invention, a guide groove is provided on the bottom surface of the first slot 112 / second slot 113, the guide groove being concealed along the length direction of the first slot 112 / second slot 113, and a guide protrusion is provided on the bottom surface of each first drive arm 211 / second drive arm 221, the guide protrusion being slidably disposed in the guide groove, so that the first drive arm 211 / second drive arm 221 can move stably in a preset direction.

[0107] As a preferred embodiment of the present invention, the outer side of the first connecting arm 212 / second connecting arm 222 is provided with a pull ring, which facilitates the pulling of the first clamping member 21 / second clamping member 22 through the ring to realize the opening and closing adjustment of the entire clamping assembly 20.

[0108] Preferably, in one embodiment of the present invention, a plurality of gears 114 are provided in the middle of both mounting slots 111, and the plurality of gears 114 are spaced apart along the width direction of the placement plate 10;

[0109] Each of the two first drive arms 211 and the gear 114 has a first rack 213 on one side opposite to each other. The first rack 213 extends along the length of the first drive arm 211 and meshes with one side of the gear 114.

[0110] Each of the two second drive arms 221 and the gear 114 has a second rack 223 on one side opposite to each other. The second rack 223 extends along the length of the second drive arm 221 and meshes with the other side of the gear 114.

[0111] Thus, by setting multiple gears 114 spaced apart along the width direction of the placement plate 10 in the middle of the mounting slot 111, and by setting a first rack 213 and a second rack 223 on the first drive arm 211 and the second drive arm 221 respectively to mesh with the two sides of the gears 114, this gear 114-rack meshing transmission method can accurately ensure that the first drive arm 211 and the second drive arm 221 move synchronously and mirrorively along the width direction of the placement plate 10, which greatly improves the synchronicity and accuracy of the movement of the clamping assembly 20, and ensures that the clamping action of the pacemaker 60 is accurate and error-free.

[0112] Preferably, in one embodiment of the present invention, the first drive arm 211 is provided with a first stepped surface 214 on the side opposite to the first rack 213, and a first elastic member 215 is provided on the first convex stepped surface, and the other end of the first elastic member 215 abuts against the groove wall of the mounting groove 111.

[0113] The second drive arm 221 has a second stepped surface 224 on one side opposite to the second rack 223. A second elastic member 225 is provided on the second stepped surface 224, and the other end of the second elastic member 225 abuts against the wall of the mounting groove 111.

[0114] Thus, the first elastic element 215 is disposed on the first stepped surface 214 of the first drive arm 211 and its other end abuts against the wall of the mounting groove 111, and the second elastic element 225 is disposed on the second stepped surface 224 of the second drive arm 221 and its other end abuts against the wall of the mounting groove 111. When the clamping assembly 20 clamps the pacemaker 60, the elastic elements can generate a certain elastic force to provide a stable clamping force for the clamping action, ensuring that the pacemaker 60 is firmly clamped and preventing the pacemaker 60 from loosening or shifting due to external factors (such as slight patient movement), thus ensuring the safety and stability of the pacemaker 60 in use.

[0115] Meanwhile, the first elastic element 215 and the second elastic element 225 provide the device with good adaptability, enabling effective fixation for pacemakers 60 of different specifications. Since different pacemakers 60 vary in size, weight, etc., the elastic elements, through their own elasticity, can automatically adjust the clamping force and position, ensuring that pacemakers 60 of various specifications can be securely clamped, greatly improving the versatility and practicality of the device. For example, the first elastic element 215 and the second elastic element 225 can be return springs.

[0116] Preferably, in one embodiment of the present invention, the upper surface of the first connecting arm 212 is provided with a plurality of first clamping portions 216, and one side of the plurality of first clamping portions 216 extends toward the upper surface of the placement plate 10 to clamp the side of the pacemaker 60.

[0117] The upper surface of the second connecting arm 222 is provided with a plurality of second clamping parts 226, and one side of the plurality of second clamping parts 226 extends toward the upper surface of the placement plate 10 to clamp the other side of the pacemaker 60.

[0118] Thus, the upper surface of the first connecting arm 212 is provided with a plurality of first clamping portions 216 extending toward the upper surface of the placement plate 10, and the upper surface of the second connecting arm 222 is provided with a plurality of second clamping portions 226 extending toward the upper surface of the placement plate 10. This allows for clamping from the side of the pacemaker 60 and increases the number of clamping points, effectively improving the clamping stability of the pacemaker 60, reducing the risk of the pacemaker 60 shaking or shifting on the placement plate 10, and ensuring the stability of the pacemaker 60 during use.

[0119] Advantageously, a rubber anti-slip layer can be provided on the contact surfaces of the first clamping part 216 and the second clamping part 226 with the pacemaker 60, so as to ensure the stability of the pacemaker 60 clamping while avoiding damage to the surface of the pacemaker 60.

[0120] Preferably, in one embodiment of the present invention, the cable management assembly 30 includes a connecting plate 31 and a plurality of winding posts 32.

[0121] The placement plate 10 has a connecting groove 115 at its tail end, and one end of the connecting plate 31 is detachably disposed in the connecting groove 115.

[0122] Multiple winding posts 32 are disposed on the upper surface of the connecting plate 31 and are distributed at intervals along the width direction of the connecting plate 31. Each winding post 32 has a limiting part 321 at its top end.

[0123] The connecting plate 31 has multiple wire-locking grooves 311 at its other end. The multiple wire-locking grooves 311 and the multiple winding posts 32 are arranged opposite to each other to partially secure the connecting wires of the pacemaker 60.

[0124] Thus, the wire management assembly 30 consists of a connecting plate 31 and multiple winding posts 32. One end of the connecting plate 31 is detachably located in the connecting groove 115 at the tail end of the placement plate 10. This detachable design facilitates the installation, disassembly, and replacement of the wire management assembly 30, allowing for adjustment or maintenance according to actual needs. The multiple winding posts 32 are spaced apart along the width of the connecting plate 31, enabling orderly winding and organization of the pacemaker 60's connecting wires, preventing them from becoming tangled and making the distribution of connecting wires clearer, thus facilitating operation and management by medical personnel. This also reduces the risk of connecting wires detaching due to pulling. Each winding post 32 has a limiting part 321 at its top. When the connecting wire is wound around the winding post 32, the limiting part 321 effectively prevents the connecting wire from slipping off the top of the winding post 32, ensuring the stability of the winding and reducing connection failures or safety hazards caused by the connecting wire detaching.

[0125] Meanwhile, during use, the connecting wire is first wound around the winding post 32, and then partially secured in the wire-holding groove 311, forming a double fixing mechanism. This enhances the fixing strength of the connecting wire and effectively prevents the connecting wire from loosening on the winding post 32 due to various factors (such as slight pulling, vibration, etc.), ensuring that the connecting wire is always in a stable and orderly state.

[0126] Specifically, in another embodiment of this utility model, elastic buckles are provided on one or both sides of the wire-holding groove 311. The elastic buckles can be made of plastic or metal with a certain degree of elasticity. The elastic buckles are L-shaped or arc-shaped, with one end fixed to the side wall of the groove and the other end being a free end that is inclined inwards towards the groove. When the connecting wire is inserted into the groove, the elastic buckle is squeezed outwards by the connecting wire. After the connecting wire passes through, the elastic buckle returns to its original shape, securing the connecting wire in the wire-holding groove 311.

[0127] Preferably, in one embodiment of the present invention, a protective cover 50 is provided on the upper surface of the placement plate 10. One end of the protective cover 50 is pivotally connected to one end of the placement plate 10, and the other end of the protective cover 50 is detachably connected to the other end of the placement plate 10 to cover the pacemaker 60. The left and right sides of the protective cover 50 are hollow, and the tail end of the protective cover 50 is provided with an outlet 51 for the pacemaker 60 connection wire to be led out.

[0128] Thus, the protective cover 50 is pivotally connected to the placement plate 10 at one end and detachably connected at the other end, allowing it to be easily placed over the pacemaker 60, providing physical protection and preventing damage or accidental activation. The protective cover 50 has openwork designs on both sides, allowing the clamping components to easily hold and secure the pacemaker 60 on the placement plate 10. The tail end of the protective cover 50 has a cable exit port 51 specifically for leading out the pacemaker 60's connecting wires. This ensures the connecting wires can be neatly and orderly led out from inside the protective cover 50, avoiding tangled wires around the cover and reducing potential safety hazards caused by messy wiring. It also facilitates the organization and handling of the connecting wires by medical personnel.

[0129] Preferably, the protective cover 50 can be made of transparent plastic, which not only ensures the strength of the protective cover 50, but also makes it easy for medical staff to observe and read the data on the pacemaker 60.

[0130] Preferably, in one embodiment of the present invention, the placement plate 10 is provided with a hooking part 13 in the middle of its bottom surface, and the fixing strap 40 is provided with a hooking ring 41 on its top surface. The hooking part 13 is detachably hooked into the hooking ring 41.

[0131] Thus, by setting a hook part 13 in the middle of the bottom surface of the placement plate 10 and a hook ring 41 on the top surface of the fixing strap 40, the two are connected by a detachable hook. This makes the installation and removal process between the placement plate 10 and the fixing strap 40 extremely simple. Medical staff do not need to use complicated tools and can complete the process with simple operations, which greatly saves operation time and effort and improves work efficiency.

[0132] For example, the hooking part 13 can be made of metal or plastic material with certain strength and toughness, such as stainless steel or acrylic, to ensure that it can withstand the weight of the placement plate 10 and pacemaker 60 and is not easily deformed or damaged. The overall design is a "J"-shaped hook. The curved part of the hook has a moderate curvature, which facilitates smooth hooking onto the hooking ring 41 and ensures stability after hooking. It is also made of stainless steel or acrylic material to ensure its durability and strength. The whole is a closed circular ring structure, and the inner diameter of the ring is slightly larger than the diameter of the straight part of the hook, usually 1-2 mm larger than the diameter of the straight part of the hook, to ensure that the hook can be easily hooked in without being too loose. Of course, this structure is only exemplary, and other connection structures can be used in actual applications.

[0133] Preferably, in another embodiment of the present invention, one end of the fixing strap 40 is provided with a connecting ring, the other end of the fixing strap 40 is provided with a hook and loop surface, and the surface of the fixing strap 40 is also provided with a hook and loop surface that can be attached to the hook and loop surface. The hook and loop surfaces are distributed at intervals and extend along the length direction of the fixing strap 40.

[0134] Thus, in the fixed type, it is only necessary to pass the other end of the fixing strap 40 through the connecting ring and fold it back, and then fix the hook and loop side to the corresponding position on the hook and loop male side to achieve fixation.

[0135] Preferably, in one embodiment of the present invention, the bottom surface of the fixing strap 40 is provided with an adhesive strap 42, the middle part of the adhesive strap 42 is connected to the middle part of the fixing strap 40, and the width of the adhesive strap 42 is greater than the width of the fixing strap 40.

[0136] Thus, because the width of the adhesive band 42 is greater than the width of the fixation band 40, the contact area between the adhesive band 42 and the patient's body is increased. This larger contact area more evenly distributes the pressure of the placement plate 10 and pacemaker 60 on the body, reducing local pressure and providing more reliable friction to prevent the fixation band 40 and placement plate 10 from sliding or shifting on the patient's body, ensuring the pacemaker 60 remains in a stable position and guaranteeing treatment effectiveness. The adhesive band 42 is made of a flexible, skin-friendly material.
