Internal nasal dilator

The anti-snoring invention comprises as internal nasal dilator having a combination of elements constructed and arranged to provide near-normal breathing for the wearer, while preventing the dilator from falling out of the nose, and without annoyance or discomfort for the wearer. To carry out the inventive concept, the internal dilator comprises a combination of several elements. First a V-shaped member, such as a flat spring is provided, with resilient pad means attached at each end thereof. A flexible nasal strip is then attached by the wearer at the central portion (outside bottom) of the V-shaped spring by adhesive means in one form of the invention, or by clamping means in another form; the nasal strip has two adhesive portions at or near the free unattached strip-ends. The spring-ends with the pad means are inserted by the wearer inside the two nostrils so the spring can spread the outer walls of the nose to increase the nasal opening for improved breathing. The adhesive portions at the free strip-ends are then pressed against the outer surfaces of the nose by the wearer to be attached thereto, for retaining the pad means in place inside the nose, so the spring and pad means do not fall out; the soft resilient pad means then prevent discomfort for the wearer. The used nasal strips are replaced daily for good hygiene, and the two pads are replaced once every 20-30 days.

Simulation experimental pipeline device and simulation experimental method of multi-phase fluid erosion and flow states

The invention provides a simulation experimental pipeline device of multi-phase fluid erosion and flow states. The simulation experimental pipeline device comprises a pipeline, a bracket, an erosion resistant storage tank, an erosion resistant pump, a ball valve, an electromagnetic flow meter, a resistance probe, a temperature meter, a pH meter and an oxygen dissolving analyzer, wherein the pipeline comprises an waved pipeline erosion test area and a horizontal pipeline erosion test area. The waved pipeline is simulated through the simulation experimental pipeline device with various inclined angles; the change of erosion rates is recorded in real time by virtue of the resistance probe; an annular sample of which the diameter is the same with the inner diameter of the pipeline is adopted in the horizontal pipeline area. A weight loss method and an electrochemical method are used for monitoring the internal erosion of the pipeline, and the flow states and the multi-phase fluid erosion at an industrial site can be truly simulated, so that the technical problem that the flow characteristic and erosion behavior in a flowing pipeline at an industrial site cannot be truly reflected through indoor dynamic erosion simulation is solved.
