What multi-lumen catheter shapes can be processed on a tip forming machine

There are many complex molding features and details that can be achieved with tip forming machines in the machining of multi-lumen catheters. Heads and R-corners (rounded corners) are common design elements, but other features are possible, as follows:

1. Head closure design :
– Flat head closure : Simple straight cut closure.
– Tapered head: conical shaped closure designed to provide guidance during insertion or connection.
– Complex geometrical head: Depending on the needs of the connection, the head may be required to have a specific shape and structure.

2. R-angle (rounded corner) :
– External R-angle: A smooth transition at the external corners of the conduit.
– Internal R-corner: A smooth transition at the corner of the internal passage of the conduit to reduce fluid resistance.

3. Channel design:
– Parallel channels: Multiple channels are arranged in parallel, commonly found in multiple conveyor systems.
– Spiral channel: Spiral or curved channel design to help increase the flexibility of the catheter.
– Bifurcated channels: Multiple channels bifurcated from the main channel for multiple operations at the same time.

4. Fitting and Connection Design :
– Luer lock connection: A standardized connection that ensures reliable connection of the catheter to other medical devices.
– Quick couplings: Designed to facilitate quick connection or disconnection of catheters.
– Customized adapters: Connectors that are customized to meet the requirements of specific medical devices.

5. surface textures and markings :
– Talc or silicone coating: reduces friction and facilitates insertion and handling.
– Colored markings: Used to differentiate between channels or to indicate the depth of the catheter.
– Ruler scale: Scale is machined on the surface of the catheter to facilitate the measurement of insertion depth by healthcare professionals.

6. Reinforcement and support structures:
– Metal or plastic spirals: embedded in the catheter to provide additional structural support and resistance to kinking.
– Mesh or braided reinforcement: Mesh is added to the outer or inner layers of the catheter for added strength.

7. Sensing and monitoring features :
– Embedded Sensors: Sensors for pressure, temperature, etc. monitoring are embedded in the catheter.
– Conductive Channels: Channels of conductive material used to transmit signals or power.

Cutting-edge molding machines are often equipped with high-precision control systems, such as numerical control (CNC) technology and computer-aided design (CAD) software, to implement these complex molding features. These machines may also incorporate the use of laser cutting, 3D printing, or micromachining technologies to produce highly customized multi-lumen catheters.
