Medical Wire Harnesses

Wire harnesses are among the products that have witnessed the fastest development, enjoy the largest market demand, and are the most convenient to install in the industries of the current era of electronics and informatization.

They are widely used in everything from common household appliances to communication devices, computers and their peripheral devices, as well as in the fields of security, solar energy, aircraft, automobiles, and military instruments and equipment.

Currently, the wire harnesses we come into contact with are assemblies of wire harnesses formed by connecting and combining various wires and cables according to different circuit numbers, hole position numbers, location numbers, and electrical principle requirements through terminals, connectors, outer protections, and related systems of different models and performances.

Wire harnesses can be classified into the following four types according to their functions:

Drive-screen wire harnesses:

• Mainly used as driving wires for various display screens and are involved in any field where display screens are used.

Control wire harnesses:

• Mainly used to connect circuit boards to control electrical signals in the fields of financial equipment, security equipment, new energy vehicles, and medical equipment.

Power control lines:

• Such as switch power lines, computer power lines, etc.

Data transmission lines:

• For uploading and downloading signals, such as HDMI, USB, and other series.

According to product applications, wire harnesses can be classified into even more types, roughly including railway locomotive wire harnesses, automobile wire harnesses, wind power generation connection wire harnesses, medical wire harnesses, communication wire harnesses, household appliance wire harnesses, industrial control wire harnesses, etc.

The following will focus on introducing medical wire harnesses.

• As the name implies, medical wire harnesses are wire harness products used for connection in medical equipment and as accessories for medical devices.
• They are the circuits of medical electronic equipment. It can be said that without wire harnesses, medical electronic equipment cannot operate normally.
• The wires used all adopt high-quality wires that have passed certification standards such as UL, VDE, CCC, and JIS.
• Commonly used medical connectors include wire-to-board connectors, D-SUB connectors, pin headers and socket headers, and aviation plugs.
• The connector brands used are generally mostly international brands such as TE, Molex, and Amphenol. System certification is generally based on 13485 medical certification, and most materials also need to meet sterilization requirements.
• Therefore, new entrepreneurs who are about to enter this industry must understand the thresholds and requirements of medical wire harnesses.
• A survey report by research institution BCC Research points out that the annual growth rate of the global home medical equipment market scale continues to rise, and medical electronics will become a new growth point for connector applications.
• Medical wire harnesses are components that form a connecting circuit by cutting electronic wires to an appropriate length according to the drawings, then crimping the contact terminals (connectors) made by stamping copper materials with wires and cables, and then molding insulators on the outside or adding metal shells, etc., and finally bundling them into wire harnesses.
• Due to the high-risk and high-precision characteristics of the medical industry, the standards for medical devices are different from those of general devices.
• In terms of the strictness of standards alone, the inspection standards for medical devices are the most stringent.
• Common wire harnesses (wire harness), power cords (power cord), FPC, FFC, and drive-screen wire harnesses (LVDS) are widely used in the connection of medical equipment.
• Next, we will introduce the wire harnesses unique to the medical industry, which belong to medical consumables and are used in conjunction with active medical devices.
• ECG Cable (Electrocardiogram Cable): It consists of several parts, including leads, connectors, cable sheaths, stress relief, and shielding shells. They work together to transmit electrical signals from the heart to the electrocardiogram machine.

SpO2 (Oxygen Saturation Sensor):

The oxygen saturation probe is an instrument for measuring the oxygen concentration in human blood, that is, the oxygen saturation. The sensor consists of two light-emitting tubes and one phototube. It transmits the signal of the oxygen content in the blood to the medical monitor for surgical patients or critically ill patients through wires, enabling real-time monitoring of changes in the patient's oxygen saturation.

IBP Adapter Cable (Invasive Blood Pressure Adapter Cable):

The disposable invasive blood pressure sensor transmits the patient's blood pressure signal to the medical monitor for surgical patients or critically ill patients through wires, enabling real-time monitoring of changes in the patient's blood pressure.
