Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically to a lead wire storage device for an electrocardiograph. Background Technology

[0002] An electrocardiograph (ECG) is a sophisticated medical electronic instrument whose core function is to detect, amplify, and record minute potential changes (usually in the millivolt range) on the human body surface caused by the electrical activity of the heart.

[0003] The core components of an electrocardiograph (ECG) machine include electrodes, leads, input circuit / amplifier, main amplifier, recording / display device, control panel, and power supply.

[0004] The lead wires are a set of dedicated cables connecting the patient's surface electrodes to the ECG machine's main unit. They are the critical channel for ECG signal transmission, responsible for transmitting the weak cardiac electrical signals (millivolt level) acquired by the electrodes to the ECG machine's amplifier input without loss or interference. The quality and connection status of the lead wires directly affect the quality of the ECG signal. Inferior or damaged lead wires can lead to signal distortion, increased interference, unstable baseline, or even failure to record, severely impacting diagnostic accuracy.

[0005] In the prior art, electrocardiograph (ECG) machines have long and numerous leads, requiring a long time to unfold and organize each time they are used, which is inconvenient. To solve the above problems, Chinese Patent No. 201920576120.4 discloses a storage box for monitor lead wires, including a winding box and a lead wire limiting box. The lead wire limiting box is located at the lower end of the winding box, and the winding box is equipped with a limiting device. The lower end of the winding box has a left notch and a right notch, and a planar spiral spring is installed inside the winding box. An inner contraction disc is installed inside the planar spiral spring. In this invention, the lead wire is fed through the left notch and wound around the planar spiral spring, then passes through the right notch. Both ends of the lead wire are limited by the lead wire limiting box. When in use, the lead wire can be pulled out. The lead wire contracts and squeezes the planar spiral spring and the inner contraction disc to lengthen the lead wire. The limiting device is used for limiting. When not in use, the limiting device is opened and the planar spiral spring and the inner contraction disc are reset so that the lead wire can be pulled back in for storage.

[0006] While the aforementioned patent allows for the organization and storage of lead wires, the winding box used to store the lead wires is located in the middle of the wires after they are unrolled. Since the lead wires between the ECG machine and the motor are often suspended in the air during clinical use, the pulling force of gravity causes instability in the connection between the motor and the patient. Furthermore, the motor connected to the lead wires cannot be housed in the winding box, leaving the electrodes unprotected and increasing the risk of damage from accidental impacts, indirectly reducing the durability of the ECG machine's lead wires and electrodes. Utility Model Content

[0007] The purpose of this invention is to provide a lead wire storage device for an electrocardiograph to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a lead wire storage device for an electrocardiograph, comprising a lead wire box and a lead wire opening disposed on the lead wire box, a lead wire wheel rotatably disposed at the junction of the lead wire box and the lead wire opening, a pulley seat slidably disposed inside the lead wire box and on one side of the lead wire wheel, a pulley rotatably disposed on the pulley seat with its axis parallel to the axis of the lead wire wheel, and an elastic element disposed inside the lead wire box; A protective cover is hinged to the outside of the take-up box, and a limit component is provided between the protective cover and the take-up box.

[0009] Preferably, roller seats are respectively provided inside the take-up box and on both sides of the take-up opening, and the take-up wheel is rotatably disposed between the two roller seats.

[0010] Preferably, the take-up box is provided with a plug-in socket, the plug-in socket is provided with a plug hole, and the pulley seat is provided with a connecting post that is slidably inserted into the plug hole.

[0011] Preferably, the elastic element is a spring disposed between the pulley seat and the plug seat, and the spring is sleeved on the outside of the connecting column.

[0012] Preferably, the pulley seat is configured in a U-shape, and the pulley is rotatably disposed within the recess of the pulley seat.

[0013] Preferably, the surface of the take-up reel is recessed inward.

[0014] Preferably, the limiting component includes a magnet one fixed to the outside of the take-up box and a magnet two fixed to the protective cover.

[0015] Preferably, the take-up box is provided with a partition, which is close to the take-up wheel and the pulley, and the partition is provided with guide holes.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model is a take-up box for accommodating lead wires. It uses the friction of the take-up wheel to take in the lead wires. The unfolding or taking in of the lead wires can only be done from the end along the electrode. The middle part of the unfolded lead wire does not have a take-up box. The unfolded lead wire is only under its own normal gravity. The normal connection and use of the lead wire and the electrode will not be affected by the take-up box.

[0017] 2. In this utility model, after the wires are stored in the cable tray, the electrodes are hidden inside the protective cover by closing it, thus protecting the electrodes and indirectly improving the durability of the electrocardiograph leads and electrodes. Attached Figure Description

Detailed Implementation

[0020] 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.

[0021] like Figures 1 to 8As shown, a lead wire storage device for an electrocardiograph includes a take-up box 1 and a take-up port 110 disposed on the take-up box 1. A take-up wheel 2 is rotatably disposed at the junction of the take-up box 1 and the take-up port 110. A pulley seat 31 is slidably disposed inside the take-up box 1 and on one side of the take-up wheel 2. A pulley 3 is rotatably disposed on the pulley seat 31 with its axis parallel to the axis of the take-up wheel 2. An elastic element is also disposed inside the take-up box 1 to prevent the pulley 3 from moving away from the take-up wheel 2.

[0022] It should be noted that a portion of the take-up reel 2 is located inside the take-up box 1, while the other portion of the take-up reel 2 extends to the outside of the take-up box 1 through the take-up port 110. This allows the take-up reel 2 to be rotated directly from the outside of the take-up box 1.

[0023] When using, such as Figures 2 to 4 As shown, the corresponding lead 41 in the electrocardiograph leads passes through the take-up box 1. One end of the lead 41, connected to the electrocardiograph, passes through the side wall of the take-up box 1 and is fixed. Specifically, a clearance hole for the lead 41 to pass through can be opened on the corresponding side wall of the take-up box 1. Limiting pads 42 for fixing the lead 41 are provided on the lead 41 and on both sides of the clearance hole. The limiting pads 42 are fixed to the lead 41 to prevent the lead 41 from moving at the clearance hole. In this way, when the lead is taken into the take-up box 1, the lead 41 can be prevented from moving out of the take-up box 1 from the clearance hole. One end of the wire 41 connected to the electrode 4 passes through the take-up port 110. At the same time, the wire 41 is located between the take-up wheel 2 and the pulley 3. Under the action of the elastic element, the wire 41 is clamped between the take-up wheel 2 and the pulley 3. Thus, when the take-up wheel 2 is rotated, the friction force can drive the wire 41 to be gradually taken into the take-up box 1. When the wire 41 is taken out, it can be directly pulled out of the take-up box 1 by pulling the electrode 4, which is simple and quick.

[0024] As one specific implementation method, such as Figure 4 and Figure 7 As shown, roller seats 13 are respectively provided inside the take-up box 1 and on both sides of the take-up port 110, and the take-up wheel 2 is rotatably disposed between the two roller seats 13.

[0025] As one specific implementation method, such as Figures 5 to 8 As shown, the cable take-up box 1 is provided with a plug-in socket 14, the plug-in socket 14 is provided with a socket 15, and the pulley seat 31 is provided with a connecting post 32 corresponding to the socket 15. The connecting post 32 is slidably disposed in the socket 15. Preferably, two sets of connecting posts 32 and corresponding sockets 15 are provided.

[0026] Specifically in this embodiment, such as Figure 6 and Figure 8As shown, the elastic element is a spring 33 disposed between the pulley seat 31 and the plug seat 14, and the spring 33 is sleeved on the outside of the connecting post 32.

[0027] Specifically in this embodiment, such as Figure 6 and Figure 8 As shown, the pulley seat 31 is configured with a "U"-shaped structure, and the pulley 3 is rotatably disposed in the recess of the pulley seat 31.

[0028] Preferably, the wheel surface of the take-up reel 2 is recessed inward, which can effectively prevent the wire from detaching from the wheel surface when moving along the take-up reel 2; the wheel surface of the take-up reel 2 is provided with anti-slip texture to increase the contact friction between the take-up reel 2 and the wire 41 and prevent slippage between the wire 41 and the take-up reel 2 when taking up the wire.

[0029] A protective cover 16 is hinged to the outer side of the take-up box 1 at the end where the electrodes 4 of the electrocardiograph are located. A limiting component is provided between the protective cover 16 and the take-up box 1 to keep the protective cover 16 in a closed state. Specifically, a hinge seat 19 is provided on the outer side of the take-up box 1, and the protective cover 16 is hinged to the hinge seat 19 via a hinge shaft.

[0030] In one specific embodiment, the limiting component includes a magnet 17 fixed to the outside of the take-up box 1 and a magnet 18 fixed to the protective cover 16. When the protective cover 16 is closed, the magnet 17 and the magnet 18 are in contact with each other and attract each other. After the lead wire 41 is taken into the take-up box 1, the electrode 4 is still exposed outside the take-up box 1. By closing the protective cover 16, the electrode 4 is hidden inside the protective cover 16, forming a protection for the electrode 4 and indirectly improving the durability of the electrocardiograph lead wire.

[0031] Furthermore, such as Figure 4 and Figure 6 As shown, a partition 11 is provided inside the take-up box 1. The partition is close to the take-up reel 2 and the pulley 3. A guide hole 12 is provided on the partition 11 for the wire 41 to pass through. The center point of the junction between the take-up reel 2 and the pulley 3 is located in the same horizontal and vertical plane as the guide hole 12. The guide hole 12 plays a guiding role in the take-up or pull-out of the wire 41, preventing the wire 41 from being bent excessively and falling off the take-up reel 2.

[0032] It is important to note that, such as Figure 1 As shown, the number of cable collection boxes 1 can be determined according to the specific number of leads in the electrocardiograph. Multiple cable collection boxes 1 are fixedly connected to each other to facilitate the storage and management of all leads.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
