| 2025 | 48.6 | 12.3% |
| 2026E | 54.6 | 12.3% |
The rapid growth of the Chinese market is mainly due to the triple drive:
- Policy-driven: The National Health and Health Commission’s “14th Five-Year Plan” Medical Equipment Industry Development Plan clearly requires that the localization rate of large-scale medical equipment in tertiary hospitals is not less than 70% by 2025, and the domestic matching rate of connectors as key basic components is still less than 45%. There is a clear policy rigid gap.
- Domestic substitution: The localization rate of large-scale imaging equipment such as CT, MRI, and DSA increased from less than 35% in 2021 to 62% in 2024, directly driving the bulk procurement demand for high-reliability connectors
- Technology breakthroughs: Domestic leading manufacturers such as AVIC Optoelectronics, Lixun Precision, etc. have passed UL/IEC 60601-1 medical safety certification and gradually entered the medium and high-end supply chain
II. Main Application Scenarios and Connector Requirements of Medical Equipment
The demand for connectors varies significantly from medical device to medical device.The following are the connector selection points for several core application scenarios:
2.1 Patient Monitoring Devices
Patient monitoring equipment is the most used scenario for medical connectors, accounting for about 40%.Including electrocardiogram monitors, blood oximeters, blood pressure monitors, body temperature monitors, etc.Such devices typically require connectors that are small in size, light in weight, easy to plug and unplug, and reliable in contact.
Main technical requirements for patient monitoring device connectors:
| Parameter Item | Typical requirements |
|---|---|
| Contact resistance | ≤10 mΩ |
| Insulation resistance | ≥1000 MΩ @500V DC |
| Withstand voltage | ≥1500V AC/1min |
| Plug life | ≥ 5000 times |
| Operating Temperature | -20℃ ~ +85℃ |
| Contact material | Copper Alloy Gold Plating |
| Insulation material | Medical grade PBT/peek/LCP |
2.2 Diagnostic imaging equipment
Diagnostic imaging equipment such as CT, MRI, ultrasound, and DR require extremely high signal integrity and anti-interference capabilities of the connector.MRI equipment must use non-magnetic connectors due to strong magnetic field environment; ultrasonic equipment requires excellent high-frequency performance and shielding effect due to high-frequency signal transmission.
The use of stand-alone connectors for large-scale imaging equipment such as CT/MRI has increased by more than 30% compared to 5 years ago. The number of internal connectors for a high-end MRI equipment can reach more than 200, covering power connections, signal transmission, data communication and other types.
2.3 Surgical and Therapeutic Equipment
Surgical robots, endoscopes, electrosurgical equipment and other therapeutic devices have the most stringent requirements for the reliability and safety of the connector.Each joint of the surgical robot requires a sophisticated connection scheme that ensures zero signal delay and zero connection failure during high-precision operations.
High-power surgical equipment (such as high-frequency electric knife, surgical robot power system) also requires the connector to have high-power bearing capacity and real-time temperature monitoring function to prevent safety accidents caused by overheating.YY/T 1897—2025 “General Technical Requirements for Medical High Power Safety Connectors” has made mandatory specifications for such products.
2.4 Home & Wearable Medical Devices
With the rise of telemedicine and home health management, home medical devices and wearable health monitoring devices are growing rapidly.The connector requirements for this type of device are more miniaturized, lightweight, low-power, and user-friendly.FPC connectors (flexible connectors) are widely used in wearable medical devices due to their thinness and flexible bending.
III. Core Reliability Standards for Medical Connectors
Medical devices are directly related to patient life safety, so connectors must meet a range of stringent international and domestic standards.Here’s what medical electronics engineers need to know about the core standards system:
3.1 Electrical Safety Standards
IEC 60601-1It is the universal standard for basic safety and basic performance of medical electrical equipment and the basis for access to medical equipment.The standard has clear requirements for insulation fit, creepage distance, electrical clearance, voltage resistance, etc. of the connector.Medical equipment is divided into Class I (with protective grounding) and Class II (double insulation), and the corresponding connector insulation design is also different.
3.2 Quality Management System Standards
ISO 13485:2016It is a medical device quality management system standard and a basic threshold for entering the medical supply chain.Connector manufacturers must be ISO 13485 certified to establish a quality management system covering the entire process of design and development, manufacturing, supply chain management, and after-sales service.Certification cycles are often as long as 18-24 months, which is also one of the important barriers to entry in the medical connector industry.
3.3 Biocompatibility Criteria
ISO 10993The series of standards specifies the requirements for the biological evaluation of medical devices.Connectors that come into direct or indirect contact with the patient must be tested for cytotoxicity, sensitization, irritation, etc. according to ISO 10993.Common medical grade plastics (e.g. medical grade PC, peek, LCP) and contact coating (e.g. gold plating) often require a full biocompatibility test report.
In addition, for fluid connectors used in medical devices, attention needs to be paid toISO 80369Series Standard.The standard is designed through the application of special interfaces to prevent misconnection between pipelines for different purposes. It is divided into ISO 80369-3 (enteral nutrition), ISO 80369-7 (vascular and subcutaneous injection) and other parts according to clinical scenarios.
3.4 Sterilization compatibility requirements
Medical connectors need to withstand different sterilization methods depending on the use scenario.Common sterilization methods and their requirements for the connector material are as follows:
| Sterilization method | Temperature/Condition | Applicable materials | Typical Applications |
|---|---|---|---|
| Autoclave | 121℃/134℃，2bar | PEEK、PPSU、PSU、LCP | Surgical instruments, reusable equipment |
| Ethylene Oxide (EtO) | Room temperature, gas sterilization | Most medical plastics | Disposable medical devices |
| Gamma rays | 25-50 kGy | PC、PEEK、PVDF、COC/COP | Disposable supplies, implantable devices |
| Hydrogen peroxide plasma | Low Temperature Plasma | Peek, PPSU, some engineering plastics | Precision endoscopic instruments |
| Electron Beam Sterilization | Electron Beam Irradiation | PC、PEEK、PVDF | Disposable medical devices |
It should be noted that repeated sterilization will accelerate the aging of the connector material and the wear of the contact coating.For example, ordinary PVC, PP, ABS and other materials usually can only withstand 50-100 sterilization cycles, while high-end engineering plastics such as peek can withstand steam sterilization more than 1000 times, and the mechanical performance retention rate is still above 97%.
IV. Material selection points for medical connectors
4.1 Insulated enclosure material
The selection of insulation materials for medical connectors needs to consider factors such as mechanical strength, temperature resistance, chemical corrosion resistance, biocompatibility, and sterilization resistance.
Comparison of performance of insulation materials for commonly used medical connectors:
| Material | Features | Strengths | Limitations |
|---|---|---|---|
| Peek (polyether ether ketone) | High strength, high temperature resistance, resistance to repeated sterilization | Good biocompatibility, withstand 1000 + steam sterilization | Higher prices |
| PPSU (polyphenylene sulfone) | High heat resistance, high impact resistance | Adapt to repeated sterilization scenarios, transparent optional | Higher cost |
| PSU (Polysulfone) | High strength, high hydrolysis stability | Repeated high-pressure disinfection at moderate cost | Impact resistance is slightly lower than PPSU |
| LCP (liquid crystal polymer) | Low dielectric, high dimensional accuracy | Suitable for high-speed signal transmission, good SMT compatibility | Welding Temperature Restricted |
| PC (polycarbonate) | Transparent and impact resistant | Moderate cost, gamma ray resistance | Moderately resistant to chemicals |
| PVDF (polyvinylidene fluoride) | Chemical corrosion resistance, high purity | Extremely low precipitate, USP Class VI | Higher prices |
| COC/COP | Very low precipitate, high transparency | Biologics/Cell Therapy Preferred | High cost and narrow processing window |
For disposable medical consumables, lower-cost materials such as PP and ABS are usually used; for equipment components that require repeated sterilization, high-end engineering plastics such as peek and PPSU are preferred; for scenarios involving biological agents or high purity requirements, COC/COP and PVDF are preferred.
4.2 Contacts and Plating
The contacts of medical connectors usually use copper alloys (phosphor bronze, beryllium copper, etc.) as the matrix material, and the surface coating is selected according to the use scenario:
- Gilding (Au): Low contact resistance, corrosion resistance, good biocompatibility, is the most commonly used coating scheme for medical connectors, usually using “nickel plating + gold plating” composite coating structure
- Tinned (Sn): Low cost, but high contact resistance and easy oxidation, generally used for low-value, low-plug times disposable products
- Silver Plating (Ag): Good conductivity, but prone to vulcanization and discoloration, less application in medical devices
The thickness of the coating is also a key factor affecting contact reliability and longevity.The thickness of the gold-plated layer of the medical-grade connector is usually between 0.2μm and 1.0μm. It is recommended to use a hard gold-plated layer of 0.5μm or more for application scenarios with high insertion and removal times and high reliability requirements.
V. Domestic Substitution Processes and Opportunities
5.1 Market penetration status
Domestic alternatives to the Chinese medical connector market exhibit distinct stratification characteristics:
Comparison of domestic substitution rates by segment:
| Field of application | Domestic substitution rate | Major Domestic Manufacturers |
|---|---|---|
| Common monitors, infusion pumps | ~82% | Multiple domestic manufacturers |
| Home medical equipment | ~75% | Lixun precision, electric connection technology, etc. |
| Mid-range imaging equipment | ~45% | AVIC optoelectronics, aerospace appliances, etc. |
| High-end imaging equipment (PET-CT, intraoperative MRI) | ＜25% | AVIC Optoelectronics (gradual breakthrough) |
| Implantable medical devices | ＜10% | Very few businesses |
It can be seen that in the field of low-end medical equipment, domestic connectors have achieved a high penetration rate; however, in areas with high barriers such as high-end imaging equipment, surgical robots, and implantable devices, domestic alternatives are still in their infancy, and the space is huge.
5.2 Breakthrough path for domestic manufacturers
Domestic medical connector manufacturers mainly achieve breakthroughs through the following routes:
- Certification first: Take the lead in obtaining authoritative certifications such as ISO 13485, IEC 60601-1, FDA 510 (k), CE MDR, etc., and establish basic qualifications for entering the medical supply chain
- Deep Synergy: Establish a joint development relationship with Mindray Medical, Lianying Medical, Neusoft Medical and other head machine factories, participate in early design (VDA development process), and form a deep binding
- Vertical Integration: Stretching upstream, mastering core capabilities such as precision molds, high-speed stamping, and automated assembly to shorten new product development cycles and reduce costs
- Differentiated positioning: Focus on segments (e.g. high-power connectors for surgical robots, flexible connectors for wearables) and build technical barriers
It is noteworthy that in 2025, the uPMR 7.0T intraoperative magnetic resonance system was mass-produced, and all 237 of its medical connectors were exclusively supplied by AVIC Optoelectronics, marking that domestic manufacturers have broken through the supply of connectors for the highest-end imaging equipment.
VI. Future Development Trends and Prospects
6.1 Miniaturization and high density
The miniaturization trend of medical devices continues to advance, especially the rapid development of wearable devices, portable diagnostic devices, and implantable devices, requiring smaller connectors and higher pin density. The proportion of FPC connectors and microplate-to-board connectors with 0.3mm spacing and even finer pitch continues to increase in medical devices.
6.2 Intelligence and Digitalization
The UDI (Unique Device Identification) system is being progressively implemented worldwide.From 2026, China’s newly registered high-risk medical connector products must also be loaded with laser etchable micro UDI codes to access the national medical device unique identification database.In the future, connectors will not only be passive connection components, but may also be embedded with sensors to achieve real-time monitoring of contact resistance, temperature, and the number of plug-ins, evolving towards intelligent connection solutions.
6.3 Green and Sustainable
Under the dual-carbon target, the green transformation of the medical device industry chain is accelerating.The proportion of bio-based materials, recycled copper, and halogen-free flame retardant materials in connectors continues to rise.Dismantling-oriented design (DfD) increases the recovery rate of precious metals to more than 95%, and full-life-cycle carbon footprint tracking becomes a standard feature of high-end suppliers.
