What Are the Applications of 4J29 Capillary Tubes in Medical Packaging?

4J29 capillary tubes are a type of Kovar alloy material with specific chemical composition and physical properties. Their coefficient of thermal expansion is similar to that of glass, and they possess excellent machinability and weldability—these characteristics have enabled them to be widely used in the field of medical packaging.

Application in Implantable Medical Device Packaging

4J29 capillary tubes play a key role in the packaging of implantable medical devices. Implantable devices such as cardiac pacemakers and neurostimulators need to operate stably in the complex internal environment of the human body for a long time. As a packaging connection component, 4J29 capillary tubes can achieve reliable hermetic sealing with insulating materials like ceramics and glass. This prevents body fluids from seeping into the device interior, avoids short circuits in the circuit, and ensures the stable electrical performance of the device. At the same time, their good biocompatibility means they do not trigger the human body’s immune rejection response, safeguarding the safety of implantable devices inside the human body.

Application in Medical Sensor Packaging

4J29 capillary tubes are also indispensable in the packaging of medical sensors. Medical sensors are used for real-time monitoring of human physiological parameters, such as blood pressure, blood glucose, and body temperature. 4J29 capillary tubes can serve as lead packaging tubes for sensors, safely isolating the sensor’s sensitive components from external circuits. This protects internal precision components from external interference and corrosion. Furthermore, their excellent high-temperature resistance allows them to adapt to the environmental changes during the sensor’s high-temperature sterilization process, ensuring that the sensor’s accuracy and reliability remain unaffected.

Application in the Packaging of Drug Delivery Systems

4J29 capillary tubes also demonstrate unique advantages in the packaging of drug delivery systems. The internal pipeline systems of devices such as micro-infusion pumps and insulin pumps require precise control of liquid flow and prevention of leakage. 4J29 capillary tubes have precise inner diameters and smooth inner walls, which can meet the high-precision requirements of drug delivery. Meanwhile, their strong corrosion resistance means they do not react chemically with drugs, ensuring the stability and effectiveness of the drugs. In addition, in the packaging and delivery devices of radioactive drugs, the shielding performance of 4J29 capillary tubes can prevent the leakage of radioactive substances, protecting the safety of medical staff and patients.

With the continuous development of medical technology, 4J29 capillary tubes, relying on their outstanding properties, will be applied more extensively and deeply in the field of medical packaging, continuing to provide strong support for the reliability and safety of medical equipment.
