[0020] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0021] like Figures 1 to 4 As shown, the utility model is a retractable ECG lead wire, which includes a reel 1. The reel 1 is cylindrical as a whole, and an observation port 13 is provided on the outside of the reel 1. The observation port 13 is convenient for observing the reeling condition of the wire 11 in the reel 1. A rotating shaft 3 is rotatably connected to the reel 1, and a baffle 4 is fixedly connected to the rotating shaft 3. Under the action of the baffle 4, the wire 11 is prevented from being entangled.

[0022] In the present invention, a wire coil 5 is sleeved on the rotating shaft 3 between the baffles 4. The wire coil 5 and the rotating shaft 3 cannot rotate. A wire 11 is wound on the wire coil 5. There are five wire coils 5 and they are evenly distributed on the rotating shaft 3. The inner ends of the wires 11 on the five wire coils 5 pass through the rotating shaft 3 and are connected to the wire interface 71 on the turntable 7. The wire interface 71 is externally connected to the lead wire main line. The outer end of the wire 11 is fixedly connected to a connector 12. There are five connectors 12 and they are connected one by one with the wire 11. Correspondingly, the colors of the five connectors 12 are white, black, red, green, and brown, respectively, corresponding to different positions, such as upper right (RA): located at the first intercostal space on the right side of the sternum and the midclavicular line; lower right (RL): located at the level of the xiphoid process on the right midclavicular line, that is, the sixth intercostal space on the right anterior axillary line; middle (C): located at the fourth intercostal space on the left side of the sternum; upper left (LA): located at the first intercostal space on the left side of the sternum and the midclavicular line; lower left (LL): located at the level of the xiphoid process on the left midclavicular line, that is, the sixth intercostal space on the left anterior axillary line.

[0023] In the present invention, the left end of the winding drum 1 is fixedly connected to the fixed drum 2, and the gear 6 is fixedly connected to the rotating shaft 3 inside the fixed drum 2. The outer periphery of the fixed drum 2 is provided with an opening, and the outer side of the fixed drum 2 is hinged to a limiting piece 10 through a coil spring. One end of the limiting piece 10 passes through the opening and is located in the fixed drum 2. The limiting piece 10 passes through the fixed drum 2 and is engaged with the gear 6. One side of the limiting piece 10 on the gear 6 is a vertical surface, and the other side is an inclined surface. When the gear 6 rotates outward, the wire 11 is pulled outward, and the gear 6 contacts the inclined surface of the limiting piece 10 and pushes the limiting piece 10 upward, so that the gear 6 can rotate; when the gear 6 rotates inward, the wire 11 is wound inward, and the gear 6 contacts the vertical surface of the limiting piece 10, and the gear 6 cannot rotate.

[0024] In the present invention, a turntable 7 is fixedly connected to the rotating shaft 3 at the right end of the winding drum 1, and a wire interface 71 is provided on the turntable 7. A circular hole 8 is provided on the lower side of the winding drum 1, and a rubber ring 9 is fixedly connected to the circular hole 8. The wire 11 passes through the rubber ring 9 and the circular hole 8. There are five circular holes 8, which are evenly distributed on the lower side of the winding drum 1. During the winding process of the wire 11, the dust on the wire 11 can be removed under the action of the rubber ring 9, which is practical.

[0025] When the wire 11 is in use, it is directly drawn out from the winding drum 1 according to the required length. During the drawing-out process, the wire 11 drives the rotating shaft 3 to rotate, and the rotating shaft 3 drives the turntable 7 and the gear 6 to rotate. When the wire 11 is drawn out, the gear 6 rotates outward. At this time, the gear 6 contacts the inclined surface of the limiting piece 10 and pushes the limiting piece 10 upward. At the same time, under the action of the vertical surface of the limiting piece 10, it is prevented from rotating back. After use, the limiting piece 10 is lifted to separate it from the gear 6, and then the turntable 7 is rotated to drive the rotating shaft 3 to rotate inward through the turntable 7, so that the wire 11 is wound on the rotating shaft 3. The operation is convenient. During the winding process of the wire 11, the dust on the wire 11 can be removed under the action of the rubber ring 9, which has good practicality.

[0026] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
