Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to an external temporary cardiac pacing electrode fixation device. Background Technology
[0002] External temporary cardiac pacing electrode fixation devices are commonly used for temporary cardiac pacing therapy. They can stably fix the pacing electrode to a specific part of the patient's body surface, ensuring good contact between the electrode and the skin, effectively transmitting electrical pulses to maintain a normal heart rhythm, helping patients get through the critical period of unstable cardiac function, and buying time for subsequent treatment.
[0003] In practice, existing external temporary cardiac pacing devices, through the combination of electrodes and pacemakers, can meet the basic needs of cardiac pacing, but the following problems still exist:
[0004] External temporary cardiac pacing devices are often used during patient rehabilitation. However, since one end of the electrode wire needs to fit against the patient's chest with the electrode pad, when the patient needs to turn over or move, the other end of the electrode wire will inevitably be pulled, causing the connection between the electrode wire and the pacemaker to loosen, which in turn affects the patient. Therefore, this application provides an external temporary cardiac pacing electrode fixation device to meet the needs. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an external temporary cardiac pacing electrode fixation device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: an external temporary cardiac pacing electrode fixation device, comprising a pacemaker body and an electrode wire disposed at one end of the pacemaker body;
[0007] A fixing component is placed at the bottom of the pacemaker body. The fixing component includes a first mounting base installed at the bottom of the pacemaker body. A sleeve is provided at the bottom of the first mounting base. A fixing block is fixedly connected to one end of the sleeve near the first mounting base, and a sliding block is slidably connected to one end of the sleeve away from the fixing block. A telescopic rod is fixedly connected to the inner cavity of the first mounting base, and an inclined block is fixedly connected to one end of the telescopic rod near the middle of the first mounting base.
[0008] A winding assembly is placed at the bottom of a first mounting base. The winding assembly includes a knob mounted on the outer surface of the electrode wire, and the outer surface of the knob is provided with a protective shell.
[0009] In a preferred embodiment, a first spring is fixedly connected to the top of the sliding block, and the end of the first spring away from the sliding block is fixedly connected to the bottom of the fixed block.
[0010] The technical effect of adopting the above technical solution is that by setting the first spring piece, the sliding block can be assisted in resetting.
[0011] In a preferred embodiment, a sliding plate is fixedly connected to one end of the inclined block near the telescopic rod, and a second spring is fixedly connected to the side of the sliding plate. The end of the second spring away from the sliding plate is fixedly connected to the inner wall of the first mounting base.
[0012] The technical effect of adopting the above technical solution is that by setting a sliding plate, the movement trajectory of the inclined block can be limited.
[0013] In a preferred embodiment, the end of the inclined block furthest from the telescopic rod is rotatably connected to a pulley.
[0014] The technical effect of adopting the above technical solution is that by setting pulleys, the wear of the inclined block can be effectively reduced and the service life of the inclined block can be extended.
[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0016] An electrode pad is located at the end of the electrode wire furthest from the pacemaker body. A connector is located on the side of the protective shell, which connects to the side of the pacemaker body to prevent the weight of the knob from affecting the electrode wire. During use, first place the electrode wire inside the protective shell, then manually turn the knob clockwise to rewind the electrode wire. This facilitates patient examination and monitoring, preventing contact with the motor wire during operation and ensuring the pacemaker's effectiveness. After installing the rewinding assembly, manually push the sliding block upwards into the recessed cavity. When the fixed block... When the device moves upward to a certain position, the top of the fixed block contacts the bottom of the inclined block, causing the inclined block to retract into the inner cavity of the first mounting base. This connects the electrode wire to the pacemaker body. After the inclined block reaches a certain position, it resets and enters the bottom of the fixed block, allowing for quick engagement of the electrode wire connection. When the electrode wire is dragged, the fixed block and the inclined block work together to prevent the connection between the electrode wire and the pacemaker body from loosening, effectively improving connection stability.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] like Figure 1 - Figure 4 As shown, this embodiment provides a technical solution: an external temporary cardiac pacing electrode fixation device, a pacemaker body 1, and an electrode wire 11 disposed at one end of the pacemaker body 1;
[0027] Fixing component 2 is located at the bottom of pacemaker body 1. Fixing component 2 includes a first mounting base 21 installed at the bottom of pacemaker body 1. A sleeve 22 is provided at the bottom of the first mounting base 21. A fixing block 23 is fixedly connected to one end of the sleeve 22 near the first mounting base 21. A sliding block 24 is slidably connected to one end of the sleeve 22 away from the fixing block 23. A telescopic rod 26 is fixedly connected to the inner cavity of the first mounting base 21. A wedge block 27 is fixedly connected to one end of the telescopic rod 26 near the middle of the first mounting base 21.
[0028] The winding assembly 3 is located at the bottom of the first mounting base 21. The winding assembly 3 includes a knob 31 mounted on the outer surface of the electrode wire 11. A protective shell 32 is provided on the outer surface of the knob 31. A first spring piece 25 is fixedly connected to the top of the sliding block 24. The end of the first spring piece 25 away from the sliding block 24 is fixedly connected to the bottom of the fixed block 23. A sliding plate 29 is fixedly connected to the end of the inclined block 27 near the telescopic rod 26. A second spring piece 28 is fixedly connected to the side of the sliding plate 29. The end of the second spring piece 28 away from the sliding plate 29 is fixedly connected to the inner wall of the first mounting base 21. The end of the inclined block 27 away from the telescopic rod 26... A pulley 210 is rotatably connected. A groove 211 is provided on the top of the first mounting base 21. An electrode pad is provided at the end of the electrode wire 1 away from the pacemaker body 1. A connector is provided on the side of the protective shell 32, connecting it to the side of the pacemaker body 1 to prevent the weight of the knob 31 from affecting the electrode wire 11. In use, the electrode wire 11 is first placed inside the protective shell 32, and then the knob 31 is manually turned clockwise to rewind the electrode wire 11. This facilitates patient examination and care, preventing contact with the electrode wire 11 during operation and thus avoiding any impact on the pacing device's performance. After winding assembly 3, manually push the sliding block 24 upward into the inner cavity of the groove 211. When the fixing block 23 moves upward to a certain position, the top of the fixing block 23 contacts the bottom of the inclined block 27, thereby causing the inclined block 27 to drive the second spring 28 to retract into the inner cavity of the first mounting base 21, thus achieving the effect of connecting the electrode wire 11 to the pacemaker body 1. By setting the sliding plate 29, the movement trajectory of the inclined block 27 can be limited. When the inclined block 27 moves to a certain position, the second spring 28 releases stress, thereby causing the inclined block 27 to reset, thus achieving the effect of retracting the bottom of the fixing block 23. The support effectively prevents the connection between the electrode wire 11 and the pacemaker body 1 from loosening during dragging. By setting the pulley 210, the movement stability of the inclined block 27 can be effectively improved and wear reduced. Similarly, when disassembly is required, the sleeve 22 is first pushed upward, which causes the top of the sliding block 24 to contact the inclined block 27, thereby causing the inclined block 27 to retract. When the sliding block 24 moves to a certain position, the inclined block 27 contacts the bottom of the sliding block 24. At this time, the fixing block 23 is pulled downward, which causes the fixing block 23 and the sliding block 24 to disengage from the inner cavity of the pulley 210.
[0029] Furthermore, such as Figure 4As shown: A slide rod 34 is fixedly connected to the side of the knob 31. One end of the slide rod 34 extends into the inner cavity of the protective shell 32. The slide rod 34 is slidably connected to the inner cavity of the protective shell 32. First, the electrode wire 11 is placed in the inner cavity of the protective shell 32. Then, the knob 31 is manually turned clockwise, so that the electrode wire 11 can be wound up by the slide rod 34. This can achieve the effect of adjusting the electrode wire 11 to a suitable length, avoiding the electrode wire 11 being too long and causing accidental contact during patient care and examination. When the patient needs to be turned over, the length of the electrode wire 11 can be extended by turning the knob 31 counterclockwise to better adapt to the patient's usage.
[0030] During the adjustment of electrode wire 11, since the winding assembly 3 is in mid-air, some shaking is inevitable, causing a slight shift in the position of knob 31. Figure 4 As shown: In this solution, a second mounting base 33 is fixedly connected to the side of the protective shell 32 away from the knob 31. A turntable 35 is rotatably connected to the inner cavity of the second mounting base 33. A third spring 36 is fixedly connected to the outer surface of the turntable 35. A locking block 37 is fixedly connected to one end of the third spring 36. The inner cavity of the second mounting base 33 has a groove that matches the top of the locking block 37. When adjusting by twisting, the third spring 36 and the locking block 37 cooperate to fix the position of the knob 31, so as to prevent the position of the knob 31 from slightly shifting when shaking occurs.
[0031] Working principle:
[0032] like Figure 1-4 As shown:
[0033] In use: First, place the electrode wire 11 inside the protective shell 32. Then, manually turn the knob 31 clockwise to wind the electrode wire 11 via the slide rod 34, thereby adjusting the electrode wire 11 to a suitable length. After installing the winding assembly 3, manually push the fixing block 23 upward into the inner cavity of the groove 211. When the fixing block 23 moves upward to a certain position, the top of the fixing block 23 contacts the bottom of the inclined block 27, thereby causing the inclined block 27 to drive the second spring 28 to retract into the inner cavity of the first mounting base 21, thus achieving the effect of connecting the electrode wire 11 to the pacemaker body 1. When the inclined block 27 moves to a certain position... When the second spring 28 is in place, it releases stress, thereby causing the inclined block 27 to reset, which in turn supports the bottom of the fixed block 23, effectively preventing the connection between the electrode wire 11 and the pacemaker body 1 from loosening when dragging occurs. Similarly, when disassembly is required, the sleeve 22 is first pushed upward, which causes the top of the sliding block 24 to contact the inclined block 27, thereby causing the inclined block 27 to retract. When the sliding block 24 moves to a certain position, the inclined block 27 contacts the bottom of the sliding block 24. At this time, the fixed block 23 is pulled downward, which causes the fixed block 23 and the sliding block 24 to disengage from the inner cavity of the pulley 210.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
