DEVICE FOR litholysis concretions in the urinary system EXPERIMENT

摘要

The invention relates to medicine, namely, to the tools and instruments used in urology.; The technical result of the proposed device is to improve the performance dissolving concrements urinary system in the experiment due to the fact that during litholysis used device allowing to carry out during the procedure permanent uniform mixing litholytic solution, hold the solution temperature is constant in all parts of the installation for litholysis, to carry out dynamic control the temperature of the mixture for dissolution and provide metered delivery litholytic sol pa and the regulation of its administration.; The device is used as follows. Pre-dried stone urinary system is placed in a plastic capsule and weighed on electronic scales. The capsule is placed in a location that will be filled with litholytic solution. The liquid in the cell was stirred with a magnetic stirrer, providing a continuous uniform distribution over the surface of stone solution. Feed litholytic solution by means of a peristaltic pump that provides ample opportunity to adjust the solution proceeds. The spent solution is removed through a special nozzle in the lid of the cell. Cell with litholytic solution is filled into distilled water thermostated chamber. The system is maintained until the thermal equilibrium. The required temperature in the chamber during the experiment is maintained by thermostat controlled temperature gauge and a reference is 37 ± 0,1 ° C. At the end of experiment, the pump is disabled, the capsule with the stone repeatedly washed with distilled water, dried in a stream of warm air at 40 ° C and then at room temperature until constant weight. Further, it is weighed and stored value of the stone weight loss, numerically equal to its solubility.; Using the proposed device allows to improve the results litholysis calculi of the urinary system. The effect of the use of the device lies in the fact that the stones dissolve much faster in time and degree litholysis, determined by mass loss of the stones, it is significantly higher.
