Tubing Connection Sleeve is a commonly used silicone accessory in medical devices. Below is a detailed introduction to it:

Material Characteristics

Excellent Biocompatibility

Made of medical-grade silicone, its main component is polydimethylsiloxane. With a simple molecular structure and no antigenic groups, the allergic rate is less than 0.1%. The stable siloxane backbone does not decompose into harmful small molecules in the human body. It has a low friction coefficient with human tissues, causing no mechanical damage to surrounding tissues, and complies with the international standard ISO9001.

Strong Chemical Stability

The bond energy of the siloxane chemical bond is as high as 452 kJ/mol, making it resistant to reactions with human tissues and medicinal liquids, as well as corrosion by chemical substances. It can withstand sterilization methods such as autoclaving and ethylene oxide, and maintains its performance after repeated sterilization.

Customizable Physical Properties

Parameters including hardness, tensile strength, and transparency can be adjusted according to medical scenarios. The hardness ranges from Shore 10A to 80A and the tensile strength is 3–8 MPa, meeting the application requirements of different Tubing Connection Sleeves.

Performance Advantages

Tubing Protection

Provides additional physical protection for tubing, preventing damage from external compression, friction, and bending. It avoids tubing rupture and deformation, thus ensuring the smooth transmission of fluids inside the tubing.

Insulation and Heat Resistance

Boasts good insulation performance, preventing electrical interference between the tubing and surrounding live components. Meanwhile, it offers a certain heat insulation effect, avoiding fluid performance degradation caused by temperature changes.

Resistance to Microbial Erosion

The silicone material itself is not prone to adsorbing bacteria and other microorganisms. It reduces microbial growth and reproduction on the tubing surface, lowers the risk of infection, and helps maintain the hygiene of the medical environment.

Application Scenarios

Infusion Equipment

Used to protect infusion tubing from being pulled apart or worn during use, ensuring the smooth progress of the infusion process.

Respiratory Equipment

For example, in ventilator tubing, the Tubing Connection Sleeve protects the tubing, maintains its integrity, ensures stable airflow transmission, and provides reliable respiratory support for patients.

Endoscope Equipment

Applied at the tubing connection part of endoscopes, it prevents tubing damage from bending and twisting operations, and reduces friction and irritation of the tubing to human tissues.

Urinary Catheters

Serves as the connection sleeve for urinary catheters. It not only protects the catheters but also reduces patients’ physical discomfort and urethral damage due to its flexibility.
