The pipe part can be bent arbitrarily, and it will not be deformed after being folded in half
Using imported silicone rubber raw materials, platinum vulcanization is odorless
The chemical properties of the product are stable and can withstand weak acid and alkali
The material has been tested for biocompatibility, cytotoxicity, NSF, etc.
Excellent transparency, tear strength, yellowing resistance
Water resistance, good air permeability, heat aging resistance and weather resistance
The silicone breathing circuit for adults is just one of them. In fact, there are two types of silicone breathing circuits for adults. The current one is 12*21 (inner tube*outer tube). This type of silicone breathing circuit is widely used in the market. A specification with a large demand, when the silicone bellows are assembled with its accessories one by one, a silicone breathing circuit is formed, because this type of pipeline can be directly used with any ventilator anesthesia machine (standard), because silicone breathing in the industry The circuit connector is also made of silicone molded, and the silicone has excellent expansion and retraction holding force and will hug it tightly, so that the bellows of any specification can be installed on the ventilator through the connector in the accessory, that is These characteristics of expansion and expansion of silicone are used. In addition, there are some differences between the adult silicone breathing circuit ventilator and the major accessories of the anesthesia machine, but the principle is to transport gas.
