The global medical tubing segment goes on to rise at a significant speed and rate. Of course, more and more medical places are using these tubes for the best outcomes and peace of mind. These tubes are safe and durable.
What should you keep in mind?
One of the main mechanical considerations for Silicone tubes or tubing is size, especially as medical device developers go on to produce ever-smaller devices and drug delivery systems. It is presently possible to generate implant-quality silicone tubing at the scale of that of even 0.007-inch x 0.014 inch. However, you know what, not all suppliers are able of doing so reliably and at the pace necessary to deliver products to market in an efficient manner.
Keep the hardness in check
Another important consideration is hardness. Generally speaking, you know extruded silicone is mostly available in durometers from Shore A 20 to Shore that of A 80. As the durometer grows, tensile strength decreases. This is hence an important factor to evaluate for devices like that of wound drains, that are put under crucial pressure when removed from the body.
Two other important mechanical factors to consider are tear strength and that of elongation. Tear strength impacts, for example, how difficult it is for a nick in the tube to that of grow. This is something to take into consideration in situations where the tube could get exposed to a sharp edge. Elongation properties link to how stretchy the tube is, which is a crucial factor for any sort of balloon devices.
Finally, the surface finish of any of the tube must be carefully evaluated. You know what, most of the times, when it is absolutely important for a tube to own minimal surface friction, you may need to coat or coil up the tube to decrease the silicone’s inherent tackiness. However, the coating should definitely be biocompatible if it is likely to come into that of contact with the body. Moreover, Tool design and processing parameters, like that of extrusion pressure, can also positively impact the surface texture of the final tube.
Proper management of volatiles and transparency
Though highly biocompatible, silicone grades and additives should definitely be considered based on the application. In instances where there’s a high level of concern, leachable testing and post-cure processing, in which this tubing is heated to +that of three hundred fifty ºf, may be assumed.
Also, keep in mind that visibility is something that is really important for certain types of devices, like that of the ones carrying fluids into or out of the body. Although silicone is somewhat naturally translucent, certain silica fillers that enhance the overall durometer can reduce or eliminate transparency. A stripe of barium simply plussed to the tube makes it absolutely visible within soft tissue, while still allowing the fluid to get viewed to verify flow.
So, discus your options with the right type of silicone tubes manufacturers and ensure that you have the right tubes in hand. After all, it is all about how you research for the right options and what you choose.
