[Hydromassage of wound surface of surgically reconstructed laryngeal lumen and upper trachea]
Abstract:
In surgical reconstruction of laryngostenosis and stenosis of the upper trachea after dissection of the scars we place laryngotracheal prosthesis (LTP) in the created lumen for a year and longer. The LTP dilator prevents regrowing the scars into the larynx and trachea until termination of the wound epithelization. The author has designed a device which provides a pulsed change in the pressure of water-filled latex balloon-dilator of the LTP. This pulsed work is realized by 7-8-s sucking out water and filling again of 1/3 of water volume in the dilator. Such procedures lasting for 20-30 min conducted 2 times a day are called hydromassage of the larynx and trachea. In 7 patients subjected to hydromassage for a full time of wearing the LTP, epithelization of the wound surface of the reconstructed part of the airways occurred within 2-2.5 months. If hydromassage was performed for half the time of LTP wearing (12 patients) epithelization occurred within 3-3.5 months.

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
