• Thin-Wall & Microbore Tubing
  

  Our Ansix® Sub-Ultra-Thin-Wall Tubing offers tight tolerances with walls as thin as 0.0005" (0.0127 mm).

  Size selection for medical thin-wall and micro-diameter tubing needs to be considered based on specific application needs and requirements. Here are some common factors and considerations:

  Purpose and function: First, the specific purpose and required functions of the pipe need to be determined. Different medical applications may require different tubing sizes. For example, infusion tubing may require a larger inner diameter and thinner wall thickness, while a minimally invasive surgical catheter may require a smaller diameter and softer materials.

  Fluid Requirements: Consider the type of fluid the pipe is intended to transport and the flow requirements. Factors such as the fluid’s viscosity, pressure, and flow rate will affect pipe size selection. A larger inner diameter can increase fluid delivery speed and efficiency, while a smaller inner diameter can reduce fluid waste and contamination.

  Operational requirements: Consider the actual operational requirements of the pipe. For example, if you need to operate in narrow passages or organs, you may need to choose smaller diameter and softer tubing. If precise injection or drug delivery is required, a smaller inner diameter and tighter tolerances may be selected.

  Material selection: The material of the pipe will also affect the selection of size specifications. Different materials have different physical and chemical properties and may have certain limitations on size specifications. For example, some materials may be better suited for making thinner walled pipe, while some materials may be better suited for making larger diameter pipe.

  Standards and specifications: Depending on the standards and specifications of your region or country, there may be some common pipe size specifications. You can refer to relevant standards and specifications to choose the size specifications that meet the requirements.

  In summary, the selection of size specifications for medical thin-walled and micro-diameter pipes requires comprehensive consideration of factors such as use, fluid requirements, operating requirements, material selection, and relevant standards and specifications. The final choice should be determined based on specific application needs and requirements.

• Medical Single & Multilumen Tubing
  
  The application materials and quality control of medical single-lumen and multi-lumen tubing are key factors to ensure the safety and reliability of the tubing. The following are some important considerations regarding applied materials and quality control:

  Application material selection:

  Biocompatibility: Applied materials must have good biocompatibility to ensure that they will not cause adverse reactions when in contact with human tissues and body fluids.

  Medical-grade materials: Medical-grade materials that comply with relevant standards for medical devices should be selected, such as polymer or metal materials that comply with relevant standards such as ISO 10993.

  Physical and chemical properties: Application materials need to have the required physical and chemical properties, such as chemical corrosion resistance, high temperature resistance, mechanical strength, etc.

  Quality control:

  Raw material control: Strict selection and control of raw materials for application materials to ensure they comply with relevant standards and specifications.

  Manufacturing process control: Strictly control manufacturing process parameters, such as temperature, pressure, speed, etc., to ensure that the size, shape and physical properties of the pipe meet the requirements.

  Inspection and testing: Carry out necessary inspection and testing, such as dimensional measurements, physical property testing, biocompatibility testing, etc., to verify the quality and performance of the pipe.

  Recording and traceability: Establish a complete quality record and traceability system to ensure that the quality of pipes is traceable and controllable.

  In addition, it is also necessary to comply with relevant regulations and standards, such as ISO 13485 quality management system and medical device-related regulatory requirements, to ensure that the quality and performance of the pipe meet the requirements of medical devices.

  In summary, the application materials and quality control of medical single-lumen and multi-lumen tubes need to comprehensively consider factors such as biocompatibility, medical-grade materials, physical and chemical properties, and carry out strict raw material control, manufacturing process control, testing and Measures such as testing, recording and traceability to ensure that the quality and performance of tubing meet the requirements of medical devices.

• AnsixTech Lubricious / Low Friction Tubing Solutions 
  
  Lubricated/low friction pipe solutions can be achieved in several ways:

  Material selection: Choose materials with low friction properties as the lining or outer layer of the pipe. For example, polytetrafluoroethylene (PTFE) is a commonly used material with low friction properties that can be used as the lining of pipes to reduce frictional resistance.

  Surface treatment: Special surface treatment is performed on the inner wall of the pipeline to reduce frictional resistance. For example, friction between the inner wall of the pipe and the fluid can be reduced by polishing, coating, or spraying a special lubricant or coating.

  Use of lubricant: Introduce appropriate lubricant inside the pipeline to reduce frictional resistance. Lubricants can be in liquid or solid form, and the appropriate lubricant is selected based on the specific application needs.

  Pipeline design optimization: By optimizing the design of the pipeline, such as reducing the bending radius, reducing the friction area of ​​the pipeline, etc., the friction resistance can be reduced.

  Control the fluid speed and pressure: Properly control the fluid speed and pressure to reduce the frictional resistance of the fluid in the pipeline. Excessive speed and pressure will increase frictional resistance, so reasonable control is required based on specific application requirements.

  The selection of lubricated/low friction piping solutions should be based on specific application needs and requirements, taking into account factors such as material selection, surface treatment, lubricant usage, piping design optimization, and control of fluid velocity and pressure. At the same time, relevant regulations and standards also need to be complied with to ensure the safety and reliability of pipelines.

  Lubricious surfaces are a critical feature of every minimally invasive device. Low friction lumens allow devices to readily access tortuous anatomy and tight spaces with a minimum of force.
