Ques #8: What are Patient Interfaces?

Ans: These cables are quite durable but require regular replacements due to wear and tear and performance upgrades.

There are three main types of patient interfaces:

  • Use-only interfaces: These include neural simulator lead sets, fetal monitoring cables, electro-surgical devices, and catheters. They are first sterilized and then packaged. They usually come in kits and are generally disposable.
  • Limited-use interfaces: These include CCU and ICU monitor cables and ECG diagnostic leads. They can handle many wear and tear but do require replacements as they can sustain damage due to exposure to chemicals and stress.
  • Long-life interfaces: As the name suggests, these cables last for an extended period as they are wear-resistant, flexible, and durable. These include cables for ECG diagnostic testing and ultrasound imaging.

Ques #9: What About Connectors?

Ans: Some cables come with connectors, and in some cases, you will have to buy a separate connector. There are different types of connectors available, including:

  • BNC connectors: Typically used with older peripheral devices, professional test equipment, and A/V equipment, these are secure locking connectors.
  • RJ-45 connectors: These cables transmit data (serial).
  • DIN connectors: These are reliable as they adhere to the standards set by the German body, Deutsches Institut für Normung.
  • DVI connectors: These transmit video to a display.

Ques #13: How Can I Protect Medical Cables From Electromagnetic Interference?

Ans: You can use various methods to control EMI noise, which has become a common problem in today’s medical instruments. Some reliable options include:

• Filters: This trick includes finding the frequency of the interfering noise and adding filtering circuits or filters to cancel it. This method is effective as a thin film capacitor, and resistor networks are quite good at suppressing unwanted signal noise. However, it may not be feasible in all cases.

• Shrink jackets: Special polyolefin heat shrinkable tubing can reduce interference.

Other techniques include using drain lines and shielding the cables. The right option depends on the level of interference and the cause behind it. You may not be able to handle the problem on your own. Hence it is best to let professionals take care of things.
