CLASS 30: Health Care.

To remove gallstones from fecal matter conveniently and quickly for diagnostic purposes to be able to use the apparatus described below, in which the feces are driven through a comminution device by means of the rinse water and be vigorously mixed with the rinse water at the same time, whereupon the whole thing becomes a collecting device which allows the diluted fecal matter to pass through it, but holds back the gallstones. Here it is Expediently, the comminuting device through the rinsing water exiting under pressure let it drift by itself and also under several collecting sieves of increasing fineness to be arranged one behind the other or one behind the other, so as to simultaneously separate one To carry out sorting.

The apparatus is shown in one embodiment in the accompanying drawing and set up as follows:

In the container respectively. Housing α are arranged directly below the collecting funnel b two superimposed vane wheels cc ¹ , the wings of which are rotated against their vertical axis d, wherein in the present the wings of both wheels are formed wave-shaped in the radial direction and the wings of the lower wheel c ¹ , which opposite to those of the upper are twisted, have teeth on the cutting edges (upper edge and peripheral edge). Under the impellers cc ¹ there is then the collecting device, which consists of several sieve trays a ¹ a ² a ^B lying one above the other, the holes of which decrease in size from top to bottom.

The axis d, which carries the impellers is mounted in a cross rail e, which is held by an associated with their right angle downward bent ends ring e ', which rests on the basket a ^1, in the proper location, namely, the whole Flügelradeinsatz can be removed after lifting the funnel b. The sieve bottom a ^{x also} forms the bottom of the housing a, while the sieve bottoms a ² a ³ sit on special small containers, which are connected to the main container α by bayonet locks.

In the embodiment shown, each impeller has eight blades, and the five blades on the left in FIG. 2 show a part of the wheel c, while the three blades on the right side show a part of the wheel c ¹ .

The masses reaching the upper impeller are conveyed downwards by the pressurized water entering the container α through the tubes ff ^{1 at} the side, which simultaneously sets both impellers into rapid rotation, and is then crushed by the vanes of the oppositely moving wheels. When the mixture passes through the sieve trays, the gallstones are retained and, owing to the different sizes of the perforations, in

the soils sorted at the same time, so that the The size and number of stones can be determined with ease.

The device can be fixed or portable and in size and shape depending on the particular type To be adapted to the circumstances.

Claims (1)

Sponsorship claims: i. An apparatus for separating gallstones for diagnostic purposes, consisting of the combination of a comminuting device for the fecal matter with a collecting device, which allows the fecal matter diluted by pressurized water during the comminution to pass through, while the gallstones are released.
An embodiment of the to exercise the under ι. characterized process serving apparatus, in which the shredding device is formed by two oppositely moving impellers cc ¹ and the collecting device by one or more sieve trays (a ¹ a ¹ a ^% ) . In the case of the under i. protected processes, the arrangement of the pressurized water inflow in such a way that the pressurized water, at the same time as the fecal matter is driven through the impellers, causes the latter to rotate in the opposite direction. For this purpose ι sheet of drawings.
