Description

Technical Field

[0001] The present application relates to the technical field of lead wire accessories, and specifically to an anti-winding structure for an electrocardiogram lead wire. Background Art

[0002] An ECG lead wire is a wire system used to connect electrodes on the patient's body to the ECG machine during an ECG examination. Its function is to transmit the weak electrical signals generated by the heart's electrical activity to the machine. By combining different leads, a multi-angle recording of these signals is generated, helping doctors analyze heart function.

[0003] A standard 12-lead electrocardiogram requires the connection of at least 10 lead wires (6 chest leads + 4 limb leads). The cables are dense and easily crossed during use. When the lead wires are needed, they need to be separated one by one before they can be used again. It is time-consuming to solve the tangled lead wires and requires frequent separation. Summary of the Invention

[0004] The purpose of this application is to provide an anti-winding structure for an electrocardiogram lead wire to solve the technical problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: an anti-winding structure for an electrocardiogram lead wire, comprising a fixed portion fixed to the outside of the lead wire, a movable portion movably sleeved on the outside of the lead wire, and a traction wire connecting the fixed portion and the movable portion;

[0006] The fixing portion includes an upper clamping plate, a lower clamping plate with one end rotatably connected to the upper clamping plate and the other end clamped to the upper clamping plate, and the fixing portion is clamped to the outside of the lead wire by the cooperation of the upper clamping plate and the lower clamping plate;

[0007] The movable part includes a concave plate, a top plate fixed to the upper end of the concave plate, a plurality of seats connected to the inner wall of the concave plate, wire grooves opened in the plurality of seats, and a plurality of balls rotatably connected to the inner wall of the wire groove.

[0008] Preferably, a movable groove is provided on the inner wall of the concave plate, and a guide rod is fixed in the movable groove. The multiple seat bodies are slidably connected in the movable groove and movably sleeved on the outside of the guide rod. Spring 2 is sleeved on the outside of both ends of the guide rod, and the two ends of the spring 2 are respectively connected to the adjacent seat body and the inner wall of the movable groove.

[0009] Preferably, the two adjacent base bodies are connected via a spreading piece, and the spreading piece is two plates rotatably connected to one side of the two adjacent base bodies respectively, and the adjacent ends of the two adjacent plates are rotatably connected.

[0010] Preferably, a branching assembly is connected inside the top plate, and the branching assembly includes a pressure seat slidably connected to the inside of the top plate, a plurality of pressure blocks slidably connected to the lower end of the pressure seat, and a plurality of limiting parts respectively fixed to the upper ends of the plurality of pressure blocks.

[0011] Preferably, the upper end of the upper splint is connected to a traction part, and one end of the traction line is connected to one side of the top plate and the other end is connected to the traction part, and the traction part includes a shell fixed to the upper end of the upper splint, a rotating column with one end rotatably connected to the inner wall of the shell and the other end rotatably connected to the upper end of the upper splint, and a torsion spring connected between the inner wall of the shell and the rotating column and driving the rotating column to reset.

[0012] Preferably, a ratchet is fixedly connected to the outside of the rotating column, and the upper end of the ratchet is rotatably connected to the inner wall of the shell, and a limiting component for limiting the ratchet is connected to the inside of the shell.

[0013] Preferably, the limiting assembly includes two cylinders movably inserted into the shell, a pressure plate fixed to the upper ends of the two cylinders, two springs respectively sleeved on the outside of the two cylinders, a limiting block fixed to the lower end of one of the cylinders, and a limiting disc fixed to the lower end of the other cylinder.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1) The present application fixes the fixed part at one end of the lead wire and movably sleeves the movable part on the outside of the lead wire. When the crossed lead wires need to be separated, it is only necessary to pull the movable part outside the lead wire to move the movable part toward the free end of the lead wire, so that the end of the lead wire close to the electrode patch can be dispersed and released, thereby achieving the dispersion of the crossed lead wires and avoiding entanglement caused by mutual squeezing or crossing of the cables.

[0016] 2) The present application is provided with a branching assembly. When the movable part moves outside the lead wire, the pressure block can apply force to the branching piece by pressing the pressure seat, so that the branching piece is unfolded, and the distance between the two adjacent seats becomes larger. In this way, in the process of the movable part dispersing the lead wires, the distance between multiple lead wires can be increased, so that the multiple lead wires form a "fan-shaped dispersion" state, which can better reduce the cross-entanglement of short lead wires such as chest leads.

[0017] 3) The present application is provided with a traction part, which can drive and pull the traction wire. When the traction wire moves, it can drive the movable part to move on the lead wire. After the movable part divides the lead wire, the traction part can make the movable part move quickly and reset, which can prevent the movable part from approaching the free end of the lead wire and affecting the use of the lead wire.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0026] See also Figure 1-6 , the present application provides a technical solution: an anti-winding structure for an electrocardiogram lead wire, comprising a fixed portion 1 fixed to the outside of the lead wire, a movable portion 2 movably sleeved on the outside of the lead wire, and a traction wire 5 connecting the fixed portion 1 and the movable portion 2;

[0027] The fixing portion 1 includes an upper clamping plate 11, and a lower clamping plate 12 having one end rotatably connected to the upper clamping plate 11 and the other end clamped to the upper clamping plate 11. The lead wire is clamped by the upper clamping plate 11 and the lower clamping plate 12.

[0028] The movable portion 2 includes a concave plate 21, a top plate 22 fixed to the upper end of the concave plate 21, a plurality of seats 23 connected to the inner wall of the concave plate 21, wire grooves 24 opened inside the plurality of seats 23, and a plurality of balls 25 rotatably connected to the inner wall of the wire grooves 24.

[0029] By adopting the above scheme, the free end of the lead wire is passed through the wire groove 24 and then the patch is fixed on one end of the lead wire, and the lead wire is placed between the upper clamping plate 11 and the lower clamping plate 12. The upper clamping plate 11 is rotated and one end of the upper clamping plate 11 is clamped with the lower clamping plate 12, so that the upper clamping plate 11 and the lower clamping plate 12 can be clamped on the outside of the other end of the lead wire. When the lead wire needs to be used, if the free end of the lead wire (that is, the end with the patch installed) is crossed, one hand pinches the fixing part 1, and the other hand pinches the top plate 22 and the concave plate 21, and then pulls the top plate 22 and the concave plate 21 toward the free end of the lead wire. During the movement, the multiple crossed lead wires can be guided and dispersed, thereby achieving the dispersion of the crossed lead wires and avoiding entanglement caused by mutual squeezing or crossing of the cables.

[0030] See also Figure 2-4 A movable groove 42 is provided on the inner wall of the concave plate 21, and a guide rod 43 is fixed in the movable groove 42. The multiple seat bodies 23 are slidably connected in the movable groove 42 and movably sleeved on the outside of the guide rod 43. Springs 44 are sleeved on the outside of both ends of the guide rod 43, and the two ends of the spring 44 are respectively connected to the adjacent seat bodies 23 and the inner wall of the movable groove 42.

[0031] The two adjacent base bodies 23 are connected via a spreading piece 45 , and the spreading piece 45 is two plates 451 rotatably connected to one side of the two adjacent base bodies 23 , respectively. The adjacent ends of the two adjacent plates 451 are rotatably connected.

[0032] The top plate 22 is internally connected to a branching assembly 4 , which includes a pressure seat 41 slidably connected to the top plate 22 , a plurality of pressure blocks 46 slidably connected to the lower end of the pressure seat 41 , and a plurality of limiting portions 47 respectively fixed to the upper ends of the plurality of pressure blocks 46 .

[0033] By adopting the above scheme, in the process of pulling the top plate 22 and the concave plate 21 toward the free end of the lead wire, the pressure seat 41 can be moved toward the direction of the pressure block 46 by pressing the pressure seat 41, and the pressure block 46 is driven to move in the opposite direction of the expansion piece 45. The lower end of the pressure block 46 applies a force to the expansion piece 45, so that the two adjacent plate bodies 451 rotate and unfold. When the two plate bodies 451 rotate and unfold, they can push the two adjacent seat bodies 23 to move, so that the distance between the two adjacent seat bodies 23 becomes larger. In this way, in the process of the movable part 2 dispersing the lead wires, the distance between the multiple lead wires can be increased, so that the multiple lead wires form a "fan-shaped dispersion" state, which can better reduce the cross-entanglement of short lead wires such as chest leads.

[0034] See also Figure 1 、 Figure 5 and Figure 6The upper end of the upper splint 11 is connected to the traction part 3, and one end of the traction line 5 is connected to one side of the top plate 22 and the other end is connected to the traction part 3, and the traction part 3 includes a shell 31 fixed to the upper end of the upper splint 11, a rotating column 32 with one end rotatably connected to the inner wall of the shell 31 and the other end rotatably connected to the upper end of the upper splint 11, and a torsion spring connected between the inner wall of the shell 31 and the rotating column 32 and driving the rotating column 32 to reset. The other end of the traction line 5 is wound around the outside of the rotating column 32.

[0035] A ratchet 33 is fixedly connected to the outside of the rotating column 32 , and the upper end of the ratchet 33 is rotatably connected to the inner wall of the housing 31 . A limiting component for limiting the ratchet 33 is connected to the inside of the housing 31 .

[0036] The limiting assembly includes two columns 34 movably inserted into the shell 31, a pressure plate 36 fixed to the upper ends of the two columns 34, two springs 35 respectively sleeved on the outside of the two columns 34, a limiting block 37 fixed to the lower end of one of the columns 34, and a limiting disc fixed to the lower end of the other column 34.

[0037] By adopting the above solution, when the movable part 2 is pulled to move outside the lead wire, the movement of the movable part 2 can pull the rotating column 32 and the ratchet 33 to rotate counterclockwise through the traction line 5. Since the design of the limit block 37 will affect the rotation of the ratchet 33, before pulling the movable part 2, it is necessary to press the pressure plate 36 with your fingers and move the pressure plate 36 toward the direction of the shell 31. The movement of the pressure plate 36 drives the column 34 and the limit block 37 to move. At the same time, the spring 1 35 is compressed. When the limit block 37 moves downward, the limit on the ratchet 33 can be cancelled. At this time, the rotating column 32 can rotate counterclockwise. The traction line 5 is paid out by the movable part 2, and the torsion spring is tightened and stored. On the contrary, if the movable part 2 completes the branching action on the lead wire, the pressure plate 36 is pressed to move the limit block 37 downward. At this time, the limit block 37 can cancel the limit on the ratchet 33, and the torsion spring releases the force and drives the rotating column 32 and the ratchet 33 to rotate clockwise. The traction line 5 is wound up by the rotating column 32, and the movable part 2 is pulled outside the lead wire toward the fixed part 1. The movable part 2 can be quickly moved and reset through the traction part 3, which can prevent the movable part 2 from approaching the free end of the lead wire and affecting the use of the lead wire.
