Bugi (expanders) - tools for research (sensing) and expansion of the natural channels and tubular organs (urethra, esophagus, cervix and other).
The urethral bugi (to increase narrowing of the urethra) are metal, stainless steel or brass; elastic, or flexible, woven silk or cotton base, impregnated Topalovym varnish or plastic (polyvinyl chloride and polyethylene).urethral bugi Buga distinguish bill, housing and pavilion, or the handle (Fig. 1).
Metal urethral bugi are straight and curved. Direct use for dilations of the urethra in women and the front part of the urethra in men; curved (with different curvature, respectively rear distortion of the male urethra) for dilations in men. In the form of curvature are distinguished: Buji of Guyana - Sinitsina, curved beak in 1/2 of circumference, Buji of Dittes with very reasonable curvature and conical beak, Buji Benecke with double curvature of the beak, Buji Rosera with a thickening-Oliwa at the end of the beak. Bugi produce various diameter: from 1 mm (called a thread) to 10 and are distinguished by numbers (on the scale of Sarrerathe scale of Charriere, Fig. 2), each room is different from that followed by 1/3 mm for Example, Buji number 30 on a scale of Sarrera has a diameter of 10 mm, No. 10-31/3 mm, and so on, the Number is usually indicated on the pavilion Buga. Produced bugi in sets: elastic from number 3 to number 30, metal from # 12 to # 30.
The use of thin metal Buga dangerous (damage to the walls of the urethra). Therefore them apply with elastic conductor, which is screwed to the bill burza Lefort.
From metal Buga somewhat less dangerous bugi Rosera with smooth Oliwa at the end, which prevents punching walls of the urethra. For research of the urethra and the introduction of medicinal substances in his rear apply capitate flexible bugi with internal orifice through which the syringe is possible to enter medicine.
otorhinolaryngological bugiBugi otorhinolaryngological used for dilations of the larynx, trachea and hearing (Evstafieva) pipe (Fig. 3). Netraditsionnyh patients expansion of the larynx can be produced by bougie of Strattera, metal bougie Ilyashenko, guttural bogami (extender): in the production of laryngectomee extend the larynx T-shaped rubber tubes Ivanov or tubes Pautova and Affectionate. For intubation with stenosis of the larynx apply special cannula. For dilations frontal-nasal fistula, created during the operation on the frontal sinus, are cannula (probes hollow) in diameter 3; 3.5 and 4 mm, bent on their long axis. Tracheal bugi are just hollow, are of different length and width control; select them individually for each patient. For the expansion of the auditory tube use a special ear bugi having on the end Pugovkina thickening in diameter !/6 up to 1 mm
Bugi esophageal used for dilations of the esophagus with the purpose of diagnosis and treatment of its services. Esophageal bugi available in lots. More likely to use semi-flexible bugi of plastics brand KMPP sample 1962 with a length of 60-80 cm and a thickness of 0.3 to 1.5 see the Shape of cylindrical, conical end (Fig. 4). Flexible metal bugi with a set screw olive different diameters (Fig. 5) apply to determine the extent and level of narrowing of the esophagus.
Rules sterilization and storage Buga. Metal and plastic bugi sterilized by boiling during 30 minutes - 1 hour or cold antiseptic disinfecting solutions for at least 3 hours. Elastic urethral bugi of cotton or silk base, impregnated Topalovym varnish, sterilized in steam-formalin chamber within 1 day. With long-term re-sterilized by boiling they shrimps, crack and break. Before using the tool is washed with sterile distilled water. Before the introduction bugi grease sterile vaseline, vegetable oil, glycerine. Plastic esophageal bugi before the introduction of the esophagus is dipped in hot water to give them flexibility and smeared with vaseline. After drinking bugi should be thoroughly washed, dried and stored in a special case. Bugi otorhinolaryngological sterilized by the General rules and stored as surgical instruments.
