Problems solved by technology

[0002] With the continuous improvement of the modernization of medical equipment, the interaction between electromagnetic conduction, electromagnetic induction and electromagnetic radiation among various medical equipment will cause interference, influence and harm to the equipment and personnel in operation under certain conditions, especially It will make the monitoring data inaccurate and lead to wrong diagnosis by doctors
Electrocardiogram machines, monitors, ultrasonic diagnostic instruments, acupuncture electrotherapy instruments and other equipment that directly contact the human body, especially equipment that monitors human biological signals, because the signal is very weak, the test results such as waveform, A distortion similar to certain lesions is superimposed on graphics and images, causing misdiagnosis, and at the same time causing micro-electric shocks, which may be life-threatening in severe cases
If it is a medical device with a computer system, when it is disturbed, the computer will cause logic errors, data loss, etc.

Embodiment 1

[0027] An anti-interference low-noise anti-interference medical cable, the structure of which is as follows figure 1 As shown, the cable is composed of twisted wire core 1 and its outer layer covered with flexible PVC polymer layer 2 and insulation layer 3 in turn. The material of twisted wire core 1 is stranded oxygen-free copper of type 6, flexible PVC polymer Material layer 2 is made of PVC, nano-scale conductive carbon black, glass fiber, antistatic masterbatch and modifier, insulating layer 3 is made of soft grade medical PVC, and sheath 4 is made of soft grade medical PVC. Made of PVC.

[0028] Class 6 stranded oxygen-free copper is made by conventional continuous drawing and continuous annealing method or pot annealing method. The composition ratio of the flexible conductive vinyl compound material is as follows according to the quality:

[0029] PVC: 50%

[0030] Nanoscale conductive carbon black: 20%

[0031] Fiberglass: 20%

[0032] Antistatic masterbatch XJ-AMB...

Embodiment 2

[0039] An anti-interference low-noise anti-interference medical cable, the structure of which is as follows figure 2 As shown, the structure of the cable is roughly the same as that of Embodiment 1, except that a shielding layer 5 is provided on the inner side of the sheath 4, so that compared with Embodiment 1, due to the addition of a flexible conductive vinyl compound as the cable core Shielding layer, better shielding effect, suitable for medical equipment or occasions with stricter requirements for anti-interference, anti-interference and low noise.

Embodiment 3

[0041] An anti-interference and low-noise medical cable is used to connect the displays of multiple medical devices and at least one emitter. Insulation over a flexible PVC polymer, and a sheath enclosing the above-mentioned two-pair core structure.

[0042] The twisted pair cores are Class 6 oxygen-free copper conductors, and the diameter of the twisted pair cores is 1.0mm.

[0043] The flexible PVC polymer is prepared by the following method:

[0044] (1) Prepare materials according to the following formula by weight percentage: PVC: 50%, nano-scale conductive carbon black: 20%, glass fiber: 20%, antistatic masterbatch XJ-AMBP: 5%, styrene-like modifier: 5%;

[0045] (2) Stir and mix PVC and modifier evenly, melt at a temperature of 160°C, add conductive carbon black, antistatic masterbatch and glass fiber, mix evenly, and then pelletize after cooling.

[0046] The flexible PVC polymer is dried at 100°C for 4 hours, the humidity before processing is controlled to be less ...
