You’ll find disposable medical cables used regularly in electrosurgical devices, ultrasonic scalpel, surgical monitoring, and so on.

Since they’re to be disposed of after the first use, they usually come pre-packaged and sterile. Some disposable medical cables are designed to withstand autoclave sterilization so that they can be suited to repeated use (only just a few times, though).

Medical CablePower Supply Cables

The UL regulation 60601 stipulates the acceptable standards for power supply medical cables. The provision holds that power plugs must be made of solid brass, and exhibit strain relief, with minimal current leakage.

The provision also states that the cords must pass the proper grounding tests.

Every equipment operates with a unique circuitry, hence the variety of power-plug blades of hospital equipment. There’s a particular blade configuration that’s the most appropriate for each unique circuitry.

Coiled Cables

These types of cables are the most appropriate for use in equipment where mobility and foldability are crucial factors. These include equipment with sliding and rotating components, including X-ray machine heads, MRI and CAT scan machines.

Retractable cords can also help you avoid the dangers of working with dangling power cords on portable mobile equipment. Unlike long cords, you won’t have to deal with entangled and knotted cords when using coiled cords.

It can significantly enhance the convenience of use of equipment. It is even more beneficial in the use of machines that run with large bunches of cords.

Patient Monitoring Cables

Devices that monitor patient information such as blood pressure, respiration, EEG, ECG, and vital signs, need cords with plenty of connectors. Since you’ll most likely make use of numerous electrodes on a patient, you’ll need various connectors.

Also, for a number of reasons, including for coming into direct contact with the patient, many monitoring cables are disposable by design. For starters, connectors are used to connect individual leads. Moreover, the leads are susceptible to wear, so you need to replace them regularly.

However, the lead components are usually the only responsive element in patient many monitoring cables, hence the low maintenance needs of these cables.

All in all, patient monitoring cables are usually made of flexible, durable materials with excellent strain relief qualities. They come with a slender finish that prevents abrasion or adhesion to a patient’s skin.

Medical CableUltrasonic Cables

Due to the need for mobility in the use of ultrasonic equipment, ergonomics is at the heart of the designs of ultrasonic cables. Because they’re carried continuously around by technicians during use, ultrasonic devices require cables that are lightweight and flexible.
