Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and specifically relates to a cable management device for electrocardiograph leads. Background Technology

[0002] An electrocardiograph (ECG) is an instrument used to record the physiological electrical signals generated during cardiac activity. Due to its mature and reliable diagnostic technology, ease of operation, reasonable price, and non-invasive nature, the ECG has become one of the most widely used medical electronic instruments in hospitals at all levels.

[0003] Electrocardiographs require lead wires for use, which branch into multiple electrode wires to connect to different parts of the patient's body. After each use, these lead wires are prone to tangling or twisting, making it very troublesome and time-consuming for medical staff to clean them up. When multiple patients need to be tested in turn throughout the day, a lot of time needs to be spent cleaning them up after each use, which affects work efficiency. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a cable management device for electrocardiograph leads.

[0005] The objective of this utility model can be achieved through the following technical solution: a cable management device for electrocardiograph leads, comprising a main unit connector, a main lead wire, a branch connector, and multiple lead wires.

The reel is used for winding the lead wires, and the reset and fixing device is used to limit the reverse rotation of the reel and to reset the reel.

[0006] The working principle of this invention is as follows: During storage, most of the lead wire is wound around a reel and stored in the connector for easy access by medical staff. When a patient needs to use the lead wire, it is pulled out of the connector, causing the reel to rotate. However, due to the reset and fixing device, the reel cannot rotate in the opposite direction, preventing the lead wire from retracting after being pulled out. After the patient finishes using the reset and fixing device, the medical staff can stop restricting the reel, reset the reel, and allow it to pull the lead wire back to its initial position. The lead wire can then be rewound onto the reel for quick storage, improving the efficiency of medical staff.
