An anti-tangling storage device for electrocardiogram lead wires Technical Field
[0001] This utility model relates to the field of medical assistive device technology, and in particular to an anti-tangling storage device for electrocardiogram lead wires. Background Technology
[0002] ECG leads are a key component of an electrocardiogram (ECG) testing system, used to connect electrodes on the human body surface to the ECG machine and transmit cardiac electrical activity signals. Their design must take into account conductivity, anti-interference ability, comfort, and durability, and they are widely used in clinical diagnosis, dynamic ECG monitoring, exercise ECG, and other scenarios.
[0003] In the existing technology, during the use of ECG leads, due to the long length of the leads, it is difficult to lay them out stably after connecting to medical equipment. Their scattered placement on the ground can lead to a messy medical environment and affect the stability of the lead connection. Furthermore, it is not convenient to stably store the leads when they are retracted. Summary of the Invention
[0004] In view of the above-mentioned shortcomings of the existing technology, this utility model proposes an anti-tangling storage device for ECG lead wires, which can stably and orderly store ECG lead wires and prevent them from tangling due to excessive length after use, thus affecting subsequent use.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An anti-tangling storage device for electrocardiogram (ECG) leads includes a base and a housing. The housing is fixedly connected to the base. A rotating shaft is rotatably connected inside the housing. A fixing plate is fixedly connected to the inner wall of the housing. The rotating shaft passes through the fixing plate and is rotatably connected to it. A turntable is fixedly sleeved on the rotating shaft. The end of the rotating shaft passes through the fixing plate and the turntable and is fixedly connected to two locking blocks. ECG leads can be wound around the peripheral walls of the two locking blocks simultaneously. A gap is provided on one side of the two locking blocks, and the middle part of the ECG lead can be locked in the gap between the two locking blocks. Openings are provided on both sides of the housing. The two ends of the ECG lead can extend through the openings to the outside of the housing and are fixedly connected to plugs.
[0007] Preferably, a protective shell is fixedly connected to the shell at the opening position, and a wear-resistant sleeve is fixedly connected inside the protective shell. The electrocardiogram lead wire can be slidably disposed on the inner wall of the wear-resistant sleeve.
[0008] Preferably, a first gear is fixedly sleeved on the rotating shaft, a handle is rotatably connected to the fixed plate, one end of the handle away from the fixed plate extends to the outside of the housing, and a second gear is fixedly sleeved on the handle's rod wall, with the first gear and the second gear meshing together.
[0009] Preferably, the two locking blocks are two semi-circular blocks formed by cutting a groove in the same cylinder from the axis. The two locking blocks are arranged symmetrically, and the edges of the locking blocks are rounded.
[0010] Preferably, an opening is provided on the side wall of the housing, and a cover plate is inserted into the inner wall of the opening of the housing, and a handle is fixedly connected to the side wall of the cover plate.
[0011] Preferably, a rubber sealing ring is fixedly sleeved on the side wall of the cover plate, and the inner wall of the rubber sealing ring is fitted into the inner wall of the housing located at the opening.
[0012] Preferably, a fixed base is fixedly connected to the edge of the turntable, a spring is fixedly connected to the inner wall of the fixed base, and a pressure plate is fixedly connected to the end of the spring away from the fixed base. The pressure plate is set as an arc-shaped plate and can press tightly against the side wall of the ECG lead wire.
[0013] Furthermore, the sidewall of the card block is set close to the sidewall of the turntable, and there are two fixing seats. The two fixing seats are symmetrically arranged with respect to the axis of the turntable, and the position of the fixing seats corresponds to the card block. The two fixing seats surround the card block in the middle.
[0014] Preferably, the inner wall of the pressure plate is provided with a plurality of spherical grooves, and the inner walls of the plurality of spherical grooves are respectively provided with rolling balls, and the plurality of rolling balls can be respectively rolled on the side wall of the electrocardiogram lead wire.
[0015] Preferably, a plurality of guide sliders are fixedly connected around the side wall of the turntable, and an annular groove is provided on the inner wall of the housing, with the guide sliders slidably disposed within the annular groove.
[0016] Preferably, the guide slider has a groove and is rotatably connected to a roller, and the roller makes rolling contact with the inner wall of the annular groove.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] By turning the handle, the second gear fixedly mounted on the rod wall rotates. Since the first gear and the second gear mesh with each other, the rotation of the second gear drives the rotation of the first gear, which in turn drives the turntable fixedly mounted on the same shaft as the first gear to rotate. When the turntable rotates, the ECG lead wire will gradually wrap around the circumference of the two locking blocks until the ECG lead wire is wound up, so that the ECG lead wire can be stably and orderly stored, preventing the ECG lead wire from getting tangled due to excessive length after use, which would affect subsequent use.
[0019] With the spring inside the fixed seat on the side wall of the turntable in a compressed state, the spring pushes the arc-shaped pressure plate to press the ECG lead wire. The ball bearings on the inner wall of the pressure plate roll into contact with the side wall of the ECG lead wire, which not only ensures the ECG lead wire is pressed and fixed to prevent it from loosening, but also reduces frictional damage to the surface of the ECG lead wire.
[0020] The plugs at both ends of the ECG leads pass through the wear-resistant sleeves inside the protective shell through the openings on both sides of the housing, extending to the outside of the housing. The wear-resistant sleeves can reduce the wear of the ECG leads when entering and exiting the housing, thus extending their service life.
[0021] The cover plate is inserted into the inner wall of the opening, which facilitates the inspection and maintenance of the internal structure of the housing. It also allows for the replacement of ECG leads of different specifications. The rubber sealing ring on the side wall of the cover plate fits into the inner wall of the housing opening, providing a sealing and protection function to prevent dust, moisture and other substances from entering the housing and affecting the ECG leads.
[0022] The guide slider on the side wall of the turntable slides in the annular groove on the inner wall of the housing. The roller inside the guide slider rolls in contact with the inner wall of the annular groove, providing guidance and support for the rotation of the turntable, making the turntable rotate more smoothly and steadily.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0030] Referring to Figures 1-5, an anti-tangling storage device for electrocardiogram (ECG) leads includes a base 1 and a housing 2. The housing 2 is fixedly connected to the upper surface of the base 1. A rotating shaft 3 is rotatably connected inside the housing 2. A fixing plate 4 is fixedly connected to the inner wall of the housing 2. The rotating shaft 3 passes through the fixing plate 4 and is rotatably connected to it. A turntable 5 is fixedly fitted on the rotating shaft 3. Two locking blocks 12 are fixedly connected to the ends of the rotating shaft 3, passing through the fixing plate 4 and the turntable 5. The two locking blocks 12 are two semi-circular blocks formed by cutting a groove in the same cylinder along its axis. The two locking blocks 12 are symmetrically arranged. ECG leads 6 are wound around the peripheral walls of the two locking blocks 12. Openings are opened on both sides of the housing 2. The two ends of the ECG leads 6 pass through the openings and extend to the outer side of the housing 2, and are fixedly connected to plugs 8. The side walls of the locking blocks 12 are set close to the side walls of the turntable 5.
[0031] A protective shell 7 is fixedly connected to the inner wall of the shell 2 at the opening. A wear-resistant sleeve 13 is fixedly connected to the inner wall of the protective shell 7. The electrocardiogram lead wire 6 is slidably arranged on the inner wall of the wear-resistant sleeve 13. A first gear 9 is fixedly sleeved on the shaft wall of the rotating shaft 3. A handle 11 is rotatably connected to the side wall of the fixing plate 4. The end of the handle 11 away from the fixing plate 4 extends to the outside of the shell 2. A second gear 10 is fixedly sleeved on the rod wall of the handle 11. The first gear 9 and the second gear 10 are meshed with each other.
[0032] A gap is provided on one side of the two card blocks 12 facing each other, and the electrocardiogram lead 6 extends to the inner wall of the gap. The edges of the card blocks 12 are rounded.
[0033] An opening is provided on the side wall of the housing 2. A cover plate 14 is inserted into the inner wall of the opening of the housing 2. A handle 15 is fixedly connected to the side wall of the cover plate 14. A rubber sealing ring 16 is fixedly fitted on the side wall of the cover plate 14. The inner wall of the rubber sealing ring 16 is fitted into the inner wall of the housing 2 at the opening.
[0034] When it is necessary to store the ECG lead 6, the operator rotates the handle 11 located on the outside of the housing 2. The rotation of the handle 11 drives the second gear 10 fixedly sleeved on its rod wall to rotate. Since the first gear 9 and the second gear 10 mesh with each other, the rotation of the second gear 10 drives the first gear 9 to rotate, which in turn drives the turntable 5 fixedly sleeved on the same rotating shaft 3 as the first gear 9 to rotate. At the same time, the rotating shaft 3 also rotates on the fixed plate 4. When the turntable 5 rotates, the ECG lead 6 will gradually wrap around the peripheral walls of the two locking blocks 12. Since the locking blocks 12 are set on one side of the turntable 5, the ECG lead 6 will be stored in the turntable 5. The wire 6, after being wound, is placed against the side wall of the turntable 5 until the ECG lead wire 6 is wound up. The gap between the two locking blocks 12 on opposite sides provides space for the ECG lead wire 6 to pass through, and can hold the middle part of the ECG lead wire 6 in the gap between the two locking blocks 12. The rounded corner design of the edge of the locking block 12 can prevent the ECG lead wire 6 from being scratched during the winding process. The ECG lead wire 6 is tightly and smoothly wound on the side wall of the turntable 5, which can stably store the ECG lead wire 6 and prevent the ECG lead wire 6 from tangling due to excessive length after use, which would affect subsequent use.
[0035] The plugs 8 at both ends of the ECG lead 6 extend from the wear-resistant sleeves 13 inside the protective shell 7 at the openings on both sides of the housing 2 to the outside of the housing 2. The wear-resistant sleeves 13 can reduce the wear of the ECG lead 6 when it enters and exits the housing 2 and extend its service life. After the ECG lead 6 is completely stored, the cover plate 14 can be inserted into the opening on the side wall of the housing 2 through the handle 15, so that the ECG lead 6 is sealed inside the housing 2. The cover plate 14 is inserted into the inner wall of the opening, which facilitates the inspection and maintenance of the internal structure of the housing 2. At the same time, different specifications of ECG lead 6 can be replaced. The rubber sealing ring 16 on the side wall of the cover plate 14 fits against the inner wall of the opening of the housing 2, which plays a sealing and protective role, preventing dust, moisture and other substances from entering the interior of the housing 2 and affecting the ECG lead 6.
[0036] When the ECG lead 6 is needed, pull the plugs 8 at both ends, and the turntable 5 will rotate in the opposite direction. With the pull of the ECG lead 6 itself and the assistance of the operator, the ECG lead 6 will be gradually released from the locking block 12 until it reaches the required length, and can then be connected to the relevant equipment through the plugs 8 for use.
[0037] To ensure the tight clamping and fixation of the ECG lead wire 6 and prevent it from loosening, as shown in Figures 1-5, a fixing seat 17 is fixedly connected to the edge of the side wall of the turntable 5. There are two fixing seats 17, which are symmetrically arranged with respect to the axis of the turntable 5. The positions of the fixing seats 17 correspond to the locking block 12, and the two fixing seats 17 enclose the locking block 12 at its axis. A spring 18 is fixedly connected to the inner wall of each fixing seat 17. A pressure plate 19 is fixedly connected to the end of the spring 18 away from the fixing seat 17. The pressure plate 19 is set directly opposite the ECG lead wire 6 wound on the locking block 12. The pressure plate 19 is set as an arc plate. The upper and lower pressure plates 19 can enclose and clamp the ECG lead wire 6 wound on the locking block 12. The inner wall of the pressure plate 19 has multiple spherical grooves, and the inner wall of each of the multiple spherical grooves is provided with rolling balls 20. The multiple balls 20 can roll and adhere to the ECG lead wire 6 wound on the locking block 12.
[0038] In some other possible embodiments, only one fixing seat 17 may be provided, that is, only one fixing seat 17 may be provided on the side wall of the turntable 5 near the edge. One fixing seat 17 can also press the ECG lead wire 6 wound on the card block 12, but the pressing effect is not as good as that of two fixing seats 17. Of course, in some other possible embodiments, three or four fixing seats 17 may also be provided on the side wall of the turntable 5 near the edge. During the winding process, the spring 18 in the fixing seat 17 provided on the edge of the turntable 5 is in a compressed state. The spring 18 pushes the arc-shaped pressure plate 19 to press the ECG lead wire 6. The ball bearings 20 on the inner wall of the pressure plate 19 roll in contact with the side wall of the ECG lead wire 6, which not only ensures the pressing and fixing of the ECG lead wire 6 and prevents it from loosening, but also reduces frictional damage to the surface of the ECG lead wire 6.
[0039] In some other possible embodiments, to make the turntable 5 rotate more smoothly and evenly, as shown in Figures 1-5, multiple guide sliders 21 are fixedly connected around the circumference of the turntable 5. An annular groove is provided on the inner wall of the housing 2. The guide sliders 21 are slidably disposed on the inner wall of the annular groove. The guide sliders 21 are provided with grooves and are rotatably connected to rollers 22. The rollers 22 can roll and contact the inner wall of the annular groove. The arrangement of the guide sliders 21 and rollers 22 can guide the rotation of the turntable 5, making the rotation of the turntable 5 more stable, improving the quality of the ECG lead wire 6 winding, and making it flatter after winding.
[0040] The guide slider 21 set on the circumference of the turntable 5 slides in the annular groove on the inner wall of the housing 2. The roller 22 inside the guide slider 21 rolls in contact with the inner wall of the annular groove, providing guidance and support for the rotation of the turntable 5, making the rotation of the turntable 5 more stable and smooth.
[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
