Our inflatable plug is made of high-toughness silicone material. When the plug is inflated to a diameter of 10cm, it will not explode when pressed down with force, and there is enough margin to meet daily use.
Maximum safe diameter: 12cm, about 40 times to manually press and inflate. Each person presses differently, and the specific number of times will be different. The number of presses at 40 times is our own test, which can be used as a reference mark.
The plug and the trachea are an integrated link design, which can be directly inflated when in use, without considering the problem of secondary connection.
The design of the connection between the trachea and the plug, in order to improve the flexibility of use, the most effective way is to match a long enough trachea. The length of the trachea of my inflatable plug is 50cm, which is enough for daily use.
