Description

ECG lead wire

technical field

The utility model relates to the technical field of electrocardiograms, in particular to an electrocardiogram lead wire.

Background technique

The electrocardiograph is often used to detect the operation of the physiological function of the human heart. It measures the potential difference of various parts of the human body through the chest leads and limb leads, and the resulting ECG waveform reflects the condition of the human heart.

The currently used ECG lead wires include multi-core shielded cables, splitters and branch lead wires. The branch lead wires include 2 upper limb lead wires, 6 chest lead wires and 2 lower limb lead wires. After the shielded cable passes through the splitter, each branch lead wire is directly separated. The ends of the chest lead wires are respectively connected with suction ball electrodes, and the ends of the upper limb lead wires and lower limb lead wires are respectively connected with electrode clips.

In clinical work, the lead wires of the electrocardiogram machine are long and easily entangled, and it takes time and effort to separate them. The lead wires need to be sorted out every time an electrocardiogram is performed. Lead wire maintenance. So it is necessary to find a way to solve this problem.

Contents of the invention

In view of the above situation, in order to overcome the defects of the prior art, the purpose of this utility model is to provide an electrocardiogram lead wire, which effectively solves the problems that the traditional lead wires are easy to be entangled during use and time-consuming and laborious to separate.

The technical solution is to include the electrocardiograph body, one end of the electrocardiograph body is provided with a motor, the motor is connected with a roller, the outer side of the roller is provided with a storage box, the side wall of the storage box is provided with a through hole, and the through hole There are baffle holes, and a plurality of lead wires that can be wound on the roller are arranged in turn on the roller. The lead wires pass through the storage box and pass through the through holes. The blocking device, the blocking device is provided with a blocking piece, and the spring is set on the lead wire between the roller and the blocking device, and one end of the spring is fixed on the storage box to form a lead wire winding , the blocking device compresses the spring, the spring is not wound, so that the blocking device is placed in the mechanism of the storage box, and the magnet piece placed on the lead wire is arranged under the spring, and the magnetism placed in the storage box and the magnetic field outside the storage box On the contrary, and the magnetic distribution on every two leads is the same.

The utility model has the advantages of ingenious structure, simple operation, straightening out the lead wires in a short time, and is not easy to be entangled together, saving time, and the lead wires can be protected and not easily damaged.

detailed description

The specific embodiments of the present utility model will be described in further detail below in conjunction with the accompanying drawings.

Provided by Fig. 1 to Fig. 3, the utility model comprises electrocardiograph body 1, and one end of electrocardiograph body 1 is provided with motor 2, and motor 2 is connected with roller 3, and the outside of roller 3 is provided with storage box 4, and storage box The side wall of 4 is provided with a through hole 5, the through hole 5 is provided with a stopper hole 6, and the roller 3 is provided with a plurality of lead wires 7 which can be wound on the roller 3 in turn, and the lead wire 7 passes through The storage box 4 passes through the through hole 5, and a blocking device 8 is provided near the end of the lead wire 7. The blocking device 8 is provided with a blocking piece 11, and a locking device 8 is provided between the roller shaft 3 and the blocking device 8. The spring 9 that is sleeved on the lead wire 7, one end of the spring 9 is fixed on the storage box 4, and when the lead wire 7 is wound on the roller 3, the blocking device 8 compresses the spring 9, and the spring 9 does not wind, so that The blocking device 8 is placed in the mechanism of the storage box 4, and the magnet sheet 10 placed on the lead wire 7 is arranged below the spring 9. The magnetism placed in the storage box 4 is opposite to that outside the storage box 4, and every two The magnetic distribution on the lead wire 7 is the same.

The blocking device 8 is integrated with the lead wire 7 and made of the same material, and the blocking device 8 is a blocking ring.

The blocking pieces 11 are two rectangular blocking pieces, which are evenly distributed on both sides of the blocking ring.

When the utility model is used,

When the lead wire 7 is not used, the lead wire 7 is wound on the roller 3, when the lead wire 7 is used, the motor 2 is started, the lead wire 7 is released from the roller 3, and the lead wire 7 is pulled , the lead wire 7 is pulled out from the storage box 4. When the lead wire 7 is used, because there are many, in order to prevent the lead wire 7 from being entangled, a spring 9 is provided on the lead wire 7, so that the lead wire 7 The outer diameter is increased, and the spring 9 has elasticity, so even when overlapping, winding is not easy to occur, and even if winding occurs, it is easy to untie.

In order to further prevent the lead wire 9 from being entangled, a magnet piece 10 is provided on the lead wire 7 between the roller 3 and the blocking device 8, and when arranging, one of the N pole and the S pole on the magnet piece 10 is It is completely placed in the storage box 4, so that when the lead wire 7 is used, there is only one pole on the lead wire 7 placed outside the storage box 4, and the pole distribution on every two lead wires 7 is the same. When the wires 7 overlap, they will also repel each other with the same sex, so as to avoid the lead wires 7 from being entangled. Although the lead wires 7 are provided with a magnet piece 10, as long as the lead wires 7 do not form a coil, the current will not be affected, that is to say There is no effect on lead 7.

After the lead wire 7 is used up, start the motor 2, and the lead wire 7 begins to be wound on the roller 3, but the spring 9 is not wound, and one end of the spring 9 is fixed in the storage box 4, and the retaining ring starts to compress the spring 9, When the retaining ring compresses the spring 9 to the storage box 4, the retaining ring can just pass through the through hole 5, and the catch 11 passes through the catch hole 6. At this time, the spring 9 is completely placed in the storage box 4, and then the catch 11 is rotated, and the catch 11 passes through the catch hole 6. The sheet 11 is stuck on the inner wall of the storage box 4, the roller 3 stops rotating, and the winding of the lead wire 7 is completed.

The utility model has the advantages of ingenious structure, simple operation, straightening out the lead wires in a short time, and is not easy to be entangled together, saving time, and the lead wires can be protected and not easily damaged.
