Reach-through holes are available in catheter wall for connecting the internal canal to environment medium. The fixing tube has reach-through hole in its wall. Intracorporal fixing ligature end is attached to distal end of the fixing tube. Extracorporal end of fixing ligature is introduced into internal canal of the fixing tube via the reach-through hole in fixing tube wall. Ligature is brought out via proximal fixing tube end, drawn through the internal catheter canal and brought out via proximal catheter end having sealing valve. Pusher having connection rod is detachable from the catheter. The fixing tube is shapable as loop holding the catheter in organ cavity. Method involves applying colonoscopy operation. The place intended for setting catheter being reached with endoscope, the fixing tube and catheter are pushed by catheter through instrumental endoscope canal into hollow organ with their distal ends forward. Pusher rod is inserted into proximal catheter end and catheter pushing through the endoscope canal goes on until the fixing tube and distal catheter end exit from endoscope canal into organ cavity. Then, the fixing ligature is pulled in holding the extracorporal end causing the fixing tube to bend as loop in intestine. The so formed loop is brought to the setting place. The loop is pressed against hollow organ wall and the endoscope is carefully withdrawn from the hollow organ. Pushing catheter into hollow organ lumen is kept on with pusher in concurrently slackening ligature out. The proximal catheter end is removed from the endoscope after withdrawing the endoscope from the organ. The pusher is detached from the catheter. Extracorporal fixing ligature end projecting from the proximal catheter end is caught and ligature slack is pulled up. Valve and catheter are attached to external catheter end. The external catheter end is fixed on body.

Granted: 2007-02-10
Abstract: FIELD: sugar industry. 
     SUBSTANCE: invention relates to technology for preparing sugar from intermediate products (backflows) at the last crystallization step. Method involves boiling down of sugar massecuite (fillmass) in vacuum-device and its unloading. Then method involves sampling the sugar massecuite unloaded from a device and isolation of intercrystal solution from it that is diluted for preparing some samples with the content of dry matters from 80% to 84%. The sugar crystals are added to these samples for saturation in the amount 20-25% to a sample mass and all samples are held at temperature 60-65°C for 1.5-2.0 h at stirring. Then intercrystal solution is isolated from them and the content of dry matters, purity and viscosity are determined in it. By taking into account data obtained the necessary temperature for cooling sugar massecuite is calculated, and the crystallization process in crystallization device is terminated after attainment of this temperature that provides the minimal purity of molasses. Invention provides the deeper desaccharification of molasses and improvement of sugar quality at the last crystallization step.
