Medical care

Connectors are key components in medical equipment that ensure the normal operation of the devices, patient safety, and the efficiency of medical processes.  Their functions run through multiple core links such as signal transmission, power supply, and fluid control.  Due to the particularity of medical scenarios, there are extremely high requirements for reliability, safety, and accuracy.  The specific functions can be analyzed from the following dimensions:
I. Signal Transmission: The "Neural Hub" of Medical Diagnosis and Monitoring
Medical devices (such as monitors, ultrasound machines, CT, MRI, etc.) rely on precise signal transmission to monitor human physiological indicators and diagnose diseases.  Connectors are the core carriers of signal pathways:

High-precision signal transmission
For devices such as electrocardiographs and electroencephalographs, connectors need to transmit weak bioelectrical signals.  Their design should reduce contact resistance, minimize electromagnetic interference (EMI), and avoid signal distortion (for example, by using a shielding layer design to suppress external electromagnetic radiation).
The connector between the ultrasonic probe and the main unit needs to transmit high-frequency ultrasonic signals to ensure image clarity.  The connector of the endoscope needs to simultaneously transmit optical signals and control signals to ensure the stability of the image and the synchronization of the instrument operation.
Multi-channel integration: Modern medical devices often need to monitor multiple indicators simultaneously (such as electrocardiogram, blood oxygen, and blood pressure).  Connectors achieve parallel transmission of multiple signals through multi-pin design, simplifying equipment wiring and enhancing integration.
Fast switching and compatibility: The connectors of some mobile devices (such as portable monitors) need to support quick plugging and unplugging, facilitating the rapid replacement of accessories or patient transfer in scenarios such as emergency rooms and operating rooms, while also being compatible with different types of sensors (such as disposable blood oxygen probes).
Ii.  Power Supply: The "Energy Interface" for the Stable Operation of Equipment
Medical equipment (such as ventilators, surgical lights, high-frequency electrosurgical knives, etc.) has strict requirements for the stability and safety of power supply.  Connectors must meet:

Reliable power supply: Ensure continuous and uninterrupted power transmission to prevent equipment shutdown due to poor contact (for example, power failure of operating room equipment may endanger patients' lives).
Adapt to power requirements: From low-power infusion pumps to high-power radiofrequency ablation devices, connectors need to match different voltage (such as DC low voltage, AC high voltage) and current specifications, and also have overload protection design (such as built-in fuses).
Anti-misinsertion and safety isolation: Through unique mechanical lock or interface shape design, it prevents the power connectors of different devices from being misinserted (for example, the high-voltage connector of a high-frequency electrosurgical knife cannot be interinserted with the low-voltage interface of ordinary devices), and at the same time, electrical isolation is achieved through insulating materials to avoid electric shock to patients or medical staff.
Iii.  Fluid and Gas Control: "Pathway Valves" for Life Support
In medical devices involving the transmission of liquids or gases (such as infusion pumps, ventilators, and anesthesia machines), connectors play a role in connecting and controlling fluid pathways:

Sterility and compatibility: Fluid connectors that come into contact with the human body (such as infusion tube connectors, hemodialysis machine tubing connectors) must be made of medical-grade materials (such as polytetrafluoroethylene, medical silicone), be biocompatible (non-toxic and non-allergenic), and be able to withstand high-temperature sterilization (such as high-pressure steam sterilization, ethylene oxide sterilization).
Leakage prevention and one-way flow: The airway connectors of the ventilator must be strictly sealed to prevent the leakage of oxygen and anesthetic gases.  Infusion connectors are often designed with check valves to prevent liquid backflow or air from entering the blood vessels.
Quick connection and safety locking: In emergency scenarios, the connectors of infusion tubes or oxygen tubes should support blind insertion or quick snap-fit designs to save operation time and ensure a firm connection (for example, the detachment of a ventilator tube in an ICU can be fatal).
Iv. Safety and Compliance: The "Bottom Line Guarantee" for Medical Scenarios
The safety of medical equipment is directly related to patients' lives, and the design of connectors must meet strict industry standards:

Biocompatibility: Connectors that come into contact with the human body or body fluids must be certified
