What are the requirements and precautions for making transparent silicone catheters?

transparent silicone hose

Let’s first talk about the impact of the extrusion process on the transparent silicone catheter. The extrusion part of the product introduced now accounts for 60%. Except for the Y-shaped port, the rest of the components are made by the extrusion process. The cross-section of the product is divided into two.The upper part is used to pass the monitoring equipment.

For example: monitoring probes are used to observe the status of the user at all times, while the lower part of the silicone catheter is a small semicircle, which is used to guide liquid medicine or blood, and is also used as a hemostatic balloon. The upper part is much smaller, but it is the core part of the whole set of products. The reason why it is not made larger is that it is necessary to control the drainage speed at all times, and it cannot be too fast or too slow.

The extruded part of the medical grade silicone hose is made of 60°-70° rubber material, all of which are made of sterile grade silicone raw materials, and the production environment is in a dust-free workshop. It can be understood that the transparent silicone catheter is carried out in a dust-free workshop from the raw material to the factory, which effectively guarantees the safety and practicability of the product. If there are suspended particles less than 10 microns on the surface of the transparent silicone catheter, it will be censored. It is judged to be unqualified, and the dust carriers in the air are exposed to the wanton flying of viruses and bacteria. In this environment, the products will inevitably be corroded, and the contact with the transparent silicone catheter will directly affect the user. This must be prevented. This is also the impact of the production environment on the transparent silicone catheter, and the transparent silicone catheter is a highly transparent product. When in use, the naked eye can see through the pipe, making it easier to observe the flow of the liquid. Transparent silicone does not add any color glue or masterbatch. Therefore, there is no need to worry about the qualitative change of the product. The original color uses platinum vulcanizing agent and nothing else is added. It is more comfortable and safe to use for medical grade silicone catheters.

After the self-extrusion process of the transparent silicone catheter is completed, the molding process needs to be coordinated to make the Y-shaped port and the extrusion drainage pipe run-in. The molded raw material and the pipe are re-vulcanized together, and demoulding is carried out after a few minutes. During the whole process, since the silicone pipe is hollow, the rubber will be softened and flow into the extruded silicone pipe during the high-temperature molding process, so that It will block the catheter, and the Y-shaped port cannot be drained, and the same is true. Therefore, in the process of making the jig, special attention must be reserved to avoid blockage.

After the transparent silicone catheter is demoulded, it is necessary to remove the burrs. Do not remove the gap too large, so as not to affect the aesthetics of the product. This is because the jig is divided into upper and lower parts, and there are some very small parts during the running-in process. Pore gaps, especially at the position of the running-in line, because these gaps cause silicone to flow into the gaps for vulcanization, so the positive and negative tolerances for the design of transparent silicone catheters should be as small as possible.
