material and is quite soft, and therefore a user feels quite comfortable when the soft nose plug is placed in the nasal cavities; due to the fact that the soft nose plug replaces fine tubes inserted into the nasal cavities, the sealing performance is good, and leakage of oxygen is avoided...
We can produce plastic cosmetic tubes & metal cosmetic tubes in wide range, different sizes, multiple decorations & functions : Two layers PE extrusion tube features: There is convenient use, soft touch, fine scalability and impact resistance and exceptional chemical stabiiy....
measured and a sample of exhaled air is obtained to measure the O2and CO2concentrations using gas analyzers. The volume of oxygen consumed, and carbon dioxide produced are calculated by analyzing the gas from the Douglas bag for the precise time period during which it was collected. This method...
If your child snores loudly or stops breathing during sleep, it may be due to an obstruction in their airway. Lack of oxygen to the brain can have serious consequences, so don’t ignore this warning sign. If your child need asleep apnea surgery, an ENT doctor will be able to advise you...

The use of electrochemical transducers for gas sensing is still in its infancy. Indeed the first gas electrochemical gas sensors are based on solid state electrochemical sensing of oxygen, carbon dioxide, nitric oxide (NOx) (Inoue, Seki, Eguchi, & Arai, 1990), (Hu et al., 2019) with only...
Such mucosal congestion of the sinuses can cause damage to the epithelium that lines the sinus with subsequent decreased oxygen tension and microbial growth (e.g., a sinus infection). The nasal turbinates are three (or sometimes four) bony processes that extend inwardly from the lateral walls ...
(1) High barrier, aluminum foil with light resistance, oxygen resistance and water resistance and other barrier properties, on the one hand can prevent external substances into the cosmetics internal, prevent cosmetics oxidation deterioration, but also can prevent the cosmetics moisture...
The acquired XPS spectra of the uncoated sensor show peaks of carbon, oxygen and silicon. The carbon signal on the surface is probably related to the carbon from the contamination layer. The XPS spectra of the APTMS, APhS, UPS, EDA and DMS modified samples contain, in addition to carbon,...
the presence of deoxidizing gas, the density of the negatively-charged oxygen at the surface would decrease, thus lowering the barrier height and resistance [35–38]. Three sets of identical sensors were incorporated (TGS822, TGS825, and TGS826) in the sensor array for the following reasons:...
