Description

Technical Field

[0001] This invention specifically relates to a rewinding device for electrocardiogram monitoring lead wires. Background Technology

[0002] Electrocardiogram (ECG) monitors are practical and sophisticated medical instruments used in hospitals. These devices can simultaneously monitor a patient's dynamic condition. They feature ECG data acquisition, storage, intelligent analysis, and early warning functions, providing doctors with a basis for emergency response and treatment, minimizing complications, and ultimately alleviating or eliminating the condition.

[0003] When using an electrocardiogram (ECG) monitor, one end of the lead wire is connected to the patient's body, and the other end is connected to the monitor to collect data. However, the lead wire is quite long and has many branches. If it becomes tangled or knotted, it will affect the normal use of the ECG monitor, and the lead wire needs to be tidied up frequently.

[0004] For example, Chinese invention patent number 202310250320.1 provides a coiling device for electrocardiogram (ECG) monitoring leads. This device uses a reel to coil the leads during use, allowing the user to freely pull out the leads for easy management. However, existing lead coiling devices require cumbersome installation steps, making it inconvenient to quickly install or remove the leads, thus causing some inconvenience during use. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention proposes an electrocardiogram (ECG) monitoring lead wire winding device to solve the technical problem mentioned in the background art: existing lead wire winding devices require cumbersome installation steps when installing lead wires by winding them into the winding device, making it inconvenient to quickly install or remove lead wires.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cardiac monitoring lead winding device, comprising multiple sets of winding units arranged side by side, wherein each winding unit includes:

[0007] The housing has a shielding shell, and the housing and the shielding shell are respectively provided with an inlet and an outlet for the lead wire to pass through.

[0008] The winding rod is provided in two sets, with one end hinged to the housing. Multiple sets of take-up reels are arranged at intervals on the winding rod. The take-up reels on one set of the winding rod can be arranged alternately with the take-up reels on the other set of the winding rod, forming a channel with the inlet and outlet for the conductor wire to pass through.

[0009] A winding mechanism is disposed within the housing and connected to the two sets of winding rods to drive the two sets of winding rods to rotate and open along their hinge point with the housing.

[0010] In a preferred embodiment, the winding mechanism includes:

[0011] Two sets of gears are provided, and are respectively located at the ends of the two sets of winding rods. The housing is provided with a mounting base, and both sets of gears are rotatably mounted on the mounting base and mesh with each other.

[0012] A drive assembly, mounted on the mounting base and connected to the gear, drives the gear to rotate in one direction to control the opening of the two sets of winding rods; and

[0013] A locking assembly, disposed on the gear and connected to the housing, is provided to lock or unlock the rotation of the gear when the winding rod is closed.

[0014] In a preferred embodiment, the driving component includes:

[0015] A mounting shaft is disposed on the gear; and

[0016] A constant force spring, one end of which is fixedly connected to the mounting shaft, and the other end of which is fixedly connected to the mounting base.

[0017] In a preferred embodiment, the locking component includes:

[0018] The mounting rod is slidably threaded along its axis on the mounting shaft, and the end of the mounting rod is provided with a first ratchet disc;

[0019] A first elastic element is disposed between the mounting shaft and the first ratchet disc; and

[0020] A second ratchet disc is disposed on the mounting base and engages with the first ratchet disc.

[0021] In a preferred embodiment, one end of the first ratchet disc is provided with a control button, and the other end of the mounting rod is retracted into the mounting shaft and can extend out of the mounting shaft and contact the control button in an adjacent set of the winding units.

[0022] In a preferred embodiment, a lever is provided on one of the winding rods, and a limiting groove is provided on the housing. The lever is movably disposed in the limiting groove and extends outward.

[0023] In a preferred embodiment, the housing is provided with a buckle and a slot, and the buckle on each group of winding units can be engaged in the slot on the adjacent group of winding units.

[0024] In a preferred embodiment, protective wheels are provided at both ends of the outlet inside the housing, and each protective wheel can rotate along its axis.

[0025] In a preferred embodiment, a fastening mechanism is provided on one side of the housing to fix one end of the lead wire. The fastening mechanism includes:

[0026] A clamping seat is provided on the housing on one side of the cable inlet;

[0027] A lifting seat is mounted on the housing in a height-adjustable manner and cooperates with the clamping seat to form a space for the guide wire to pass through. A control lever is provided on the lifting seat.

[0028] A baffle is disposed on the housing; and

[0029] The second elastic element is disposed between the baffle and the lifting seat.

[0030] In a preferred embodiment, a wire stop plate is provided on the take-up bar on one side of the take-up reel.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] 1. In use, the device first controls the two sets of winding rods to close, so that the multiple winding wheels on the two sets of winding rods are arranged in an alternating manner to form a channel for the lead wire to pass through. The lead wire can then be inserted through the inlet and exited through the outlet. After the lead wire has passed through, the winding mechanism drives the two sets of winding rods to rotate in opposite directions to open them. Then, the multiple winding wheels will retract the lead wire into the housing. Furthermore, by pulling the lead wire, the two sets of winding rods can be rotated along their hinge point with the housing, making it easy to pull out the lead wire for use. This device allows for quick installation and removal of the lead wire without the need to wind the lead wire during use, thus improving the convenience of use.

[0033] 2. During the use of the lead wires, this device secures one end of the lead wire via a fastening mechanism. Pulling the other end extends the lead wire, causing two sets of take-up rods to rotate. During rotation, the take-up rods deform a constant-force spring, applying a restoring force. The first and second ratchet discs work together to provide unidirectional self-locking. When multiple lead wires need to be retracted, pressing the control button at the far end slides one set of mounting rods along its axis, disengaging the corresponding first ratchet disc from the second. The mounting rods then abut against the mounting rods in adjacent take-up units, causing multiple mounting rods to slide simultaneously, disengaging multiple first ratchet discs from the second. This quickly releases the lock on multiple take-up rods, which then rapidly reset under the constant-force spring, facilitating rapid retraction of multiple lead wires and further enhancing the device's practicality.

[0048] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0049] Example:

[0050] like Figures 1 to 4 As shown, the present invention provides an electrocardiogram monitoring lead winding device, comprising multiple sets of winding units arranged side by side. Each winding unit includes a housing 101, a shielding shell 201 on the housing 101, an inlet 108 and an outlet 202 on the housing 101 and the shielding shell 201 respectively for the lead wire to pass through and exit, a buckle 103 on the housing 101, and a slot 104 on the housing 101. The buckle 103 on each set of winding units can be locked into the slot 104 on the adjacent set of winding units.

[0051] During use, a suitable number of winding units can be selected for assembly. During installation, simply snap the buckle 103 into the corresponding slot 104 to complete the assembly of multiple winding units, facilitating the winding of different numbers of lead wires. In use, one end of the lead wire can be inserted into the inlet 108 and extended through the outlet 202. Protective wheels 107 are provided at both ends of the outlet 202 within the housing 101. These protective wheels 107 can rotate along their axis, protecting the lead wire from friction and damage when it is pulled.

[0052] like Figure 1 , 2As shown, in this embodiment, a fastening mechanism is provided on one side of the housing 101 to fix one end of the lead wire. The fastening mechanism includes a clamping seat 305 located on the housing 101 on the side of the inlet 108. A lifting seat 301 is provided on the housing 101 and can be raised and lowered. The lifting seat 301 and the clamping seat 305 cooperate to form a space for the lead wire to pass through. A control rod 302 is provided on the lifting seat 301. A baffle 303 is provided on the housing 101, and a second elastic member 304 is provided between the baffle 303 and the lifting seat 301.

[0053] When installing the lead wire, the control lever 302 can be pulled to slide the lifting seat 301 and squeeze the second elastic element 304, thereby exposing the inlet 108. The lead wire can then be inserted into the inlet 108. After the lead wire is fully inserted, the lifting seat 301 is reset under the action of the second elastic element 304, and the clamping seat 305 clamps the end of the lead wire, thereby preventing one end of the lead wire from moving during use. The device can also be fixedly installed with the ECG monitor, preventing excessive force when pulling the other end of the lead wire, which could cause the lead wire to detach from the ECG monitor.

[0054] like Figures 1 to 4 As shown, in this embodiment, two sets of take-up rods 401 are hinged inside the housing 101. Multiple sets of take-up wheels 403 are arranged at intervals on the take-up rods 401. The take-up wheels 403 on one set of take-up rods 401 can be arranged alternately with the take-up wheels 403 on the other set of take-up rods 401, and form a channel for the conductor wire to pass through with the inlet 108 and the outlet 202.

[0055] When the lead wire passes through the device via the inlet 108 and outlet 202, the take-up reels 403 on the two sets of take-up bars 401 are located on both sides of the lead wire. Controlling the two sets of take-up bars 401 to rotate in opposite directions increases the angle between them, allowing the take-up reels 403 to wind up the taut lead wire. A baffle plate 109 is provided on one side of the take-up reels 403 on the take-up bar 401 to block the gap formed by the multiple take-up reels 403, preventing the lead wire from passing through the gap between the two sets of take-up reels 403. After the lead wire passes through, pulling the end of the lead wire extending from the outlet 202 rotates the two sets of take-up bars 401, reducing the angle between them and facilitating the use of the lead wire.

[0056] like Figure 5 , 6As shown in Figure 7, in this embodiment, a winding mechanism connected to two sets of winding rods 401 is provided inside the housing 101. The winding mechanism drives the two sets of winding rods 401 to rotate and open along their hinge points with the housing 101. The winding mechanism includes two sets of gears 402, which are respectively disposed at the ends of the two sets of winding rods 401. A mounting base 106 is provided on the housing 101, and both sets of gears 402 are rotatably mounted on the mounting base 106 and mesh with each other. One set of winding rods 401 is provided with a lever 404, and a limiting groove 102 is provided on the housing 101. The lever 404 is movably disposed in the limiting groove 102 and extends outward.

[0057] The lever 404 can be moved to slide along the limiting groove 102, thereby causing one set of winding rods 401 to rotate along the hinge point between it and the mounting base 106. During the rotation of one set of winding rods 401, the gear 402 is rotated. Then, through the cooperation of the two sets of gears 402, the other set of winding rods 401 is controlled to rotate in the opposite direction, so as to cooperate with multiple sets of take-up wheels 403 to quickly take up the lead wire, and no large space is required when taking up the lead wire.

[0058] like Figure 5 , 6 As shown in Figure 7, in this embodiment, the winding mechanism further includes a drive assembly disposed on the mounting base 106 and connected to the gear 402. The drive assembly drives the gear 402 to rotate in one direction to control the opening of the two sets of winding rods 401. The drive assembly includes a constant force spring 502 and a mounting shaft 501 disposed on the gear 402. One end of the constant force spring 502 is fixedly connected to the mounting shaft 501, and the other end is fixedly connected to the mounting base 106.

[0059] When the guide wire is pulled, the angle between the two sets of winding rods 401 decreases, causing the gear 402 to rotate. During the rotation of the gear 402, the mounting shaft 501 rotates, thereby controlling the deformation of the constant force spring 502. When the winding rod 401 and the guide wire are not subjected to external force, the winding rod 401 is driven to rotate under the restoring ability of the constant force spring 502, which increases the angle between the two sets of winding rods 401 to quickly wind up the guide wire.

[0060] like Figure 1 , 5As shown in Figures 6 and 7, in this embodiment, the winding mechanism further includes a locking assembly disposed on the gear 402 and connected to the housing 101. The locking assembly locks or unlocks the rotation of the gear 402 when the winding rod 401 is closed. The locking assembly includes a mounting rod 503 slidably passing through the mounting shaft 501 along its axis. A first ratchet disc 504 is provided at the end of the mounting rod 503. A first elastic element 506 is provided between the mounting shaft 501 and the first ratchet disc 504. A second ratchet disc 105 is provided on the mounting base 106. The first ratchet disc 504 meshes with the second ratchet disc 105. A control button 505 is provided at one end of the first ratchet disc 504. The other end of the mounting rod 503 is retracted into the mounting shaft 501 and can extend out of the mounting shaft 501 to contact the control button 505 in an adjacent set of winding units.

[0061] As the lead wire is pulled, causing the two sets of retractor rods 401 to rotate along their hinge point with the mounting base 106, the mounting shaft 501 and the mounting rod 503 mounted on it rotate. During the rotation of the mounting rod 503, the first ratchet disc 504 rotates, and under the action of the first elastic element 506, the first ratchet disc 504 is always engaged with the second ratchet disc 105, thereby providing one-way self-locking for the first ratchet disc 504. This prevents the retractor rods 401 from rotating under the reset of the constant force spring 502 during use and pulling the lead wire, causing the lead wire to detach from the patient's body. Furthermore, by pressing one of the control buttons 505 with a little force, the mounting rod 503 can be moved to slide along its axis within the mounting shaft 501, resulting in a large sliding distance for the mounting rod 503. Through the mutual abutment of multiple sets of mounting rods 503, multiple sets of mounting rods 503 can slide simultaneously, causing multiple sets of first ratchet discs 504 to disengage from the second ratchet disc 105 at the same time. This allows for quick release of the position locking of the mounting rods 503 in multiple sets of winding units, facilitating the rapid and one-time winding up of multiple sets of lead wires.

[0062] Specific usage and beneficial effects of the present invention:

[0063] In use, the device first controls the two sets of winding rods 401 to close, so that the multiple sets of take-up wheels 403 on the two sets of winding rods 401 are arranged in an alternating manner to form a channel for the lead wire to pass through. The lead wire can then be inserted through the inlet 108 and exited through the outlet. After the lead wire has passed through, the two sets of winding rods 401 can be driven to rotate in opposite directions to open under the action of the constant force spring 502. Then, the multiple sets of take-up wheels 403 will retract the lead wire into the housing 101. Furthermore, by pulling the lead wire, the two sets of winding rods 401 can be rotated along their hinge point with the housing 101 to facilitate the pull-out of the lead wire for use. This device can quickly install and remove the lead wire without the need to wind the lead wire during use, thus improving the convenience of use.

[0064] During the use of the lead wire, the device pushes the lifting seat 301 downward through the second elastic element 304, and fixes one end of the lead wire with the clamping seat 305. By pulling the other end of the lead wire, the lead wire is extended for use, and the two sets of winding rods 401 are rotated. During the rotation of the winding rods 401, the constant force spring 502 is deformed to apply a reset force to the winding rods 401. Under the cooperation of the first ratchet disc 504 and the second ratchet disc 105, the winding rods 401 are unidirectionally self-locked. When multiple sets of lead wires need to be wound up, the control button 505 at the far end can be pressed to drive one set of mounting rods 503 to slide along its axis, so that the corresponding set of first ratchet discs 504 disengages from the second ratchet disc 105. The mounting rods 503 abut against the mounting rods 503 in the adjacent winding unit, causing multiple sets of mounting rods 503 to slide simultaneously, so that multiple sets of first ratchet discs 504 disengage from the second ratchet disc 105 at the same time. This quickly releases the lock on multiple sets of winding rods 401, and the multiple sets of winding rods 401 can quickly reset under the action of constant force spring 502, which facilitates the rapid winding of multiple sets of lead wires and further improves the practicality of the device.

[0065] The foregoing has shown and described the basic principles and main features of the present invention and its advantages. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments.
