the analyzing device shown in fig1 can be of an elastic ( or flexible ) or rigid plastic . the device contains a measuring compartment 1 , that is to be filled completely with the test solution . the measuring compartment 1 is connected to a reaction compartment 5 via a transfer device , which comprises a canal part 2 that is open at 3 and a tube - shaped part 4 that is open in the end adjacent the canal part 2 , and at its other end passes into the reaction compartment 5 . the reaction compartment 5 is closed at the end opposite to the canal 2 . in the reaction compartment 5 is shown a reagent in the form of a tablet 6 that is retained by a neck 7 of reduced diameter . when the measuring compartment 1 is placed into a liquid , the measuring compartment 1 is filled with the liquid . the outer end of the measuring compartment 1 is hydrophobic , or as shown in fig1 is shaped with a radially inward projecting flange 8 that prevents the liquid from flowing out through the outer opening . when the device is lifted , so that the measuring compartment is above the canal 2 , the liquid in the measuring compartment will flow via the canal 2 and the tube - shaped part 4 down into the reaction compartment 5 , whereupon one substance in the liquid can react with the reagents in the tablet 6 . fig2 shows another embodiment of the invention which can be made of thin elastic plastic , such as polyethylene , polypropylene , or soft polyvinylchloride , which can be assembled by gluing or welding . the reagents and / or dilutents ( diluting fluids ) are presents in ampoules 11 , 12 . by the mentioned gluing or welding , edges 9 , 10 are formed where the walls meet . on the outside of the device is shown the ampoule 11 . within the device is shown the ampoule 12 , which by constrictions or gluing is prevented from slipping out of the reaction compartment 5 into the tube part 4 . in a corresponding manner , additional ampoules can be present within or on the outside of the device . the ampoules are preferably constructed so that they have at least one wall - piece or seal that is weakened , or they may be made of fragile material that may be split or at least broken , whereby the ampoule can be emptied into the reaction compartment 5 when compressing the device from the outside . measuring and transfer of the liquid to be tested is made in the manner described above with respect to the embodiment of fig1 . fig3 shows another embodiment that can be made of flexible or rigid material . in the latter case , it is preferable that the outer wall of the device at the ampoule position , around the compartment 5 , be made of flexible material , so that it is possible to compress and empty the ampoule of its contents . the device is used in the manner described above with respect to the embodiments of fig1 and 2 . it is also contemplated in this invention that the ends of the measuring compartments 1 , remote from the reaction compartments 5 , in the embodiments of fig1 through 3 could be completely closed . fig4 shows another embodiment that can be made of flexible as well as rigid material . in the latter case , it is advantageous that the outer wall of the tube - shaped part 4 , that is situated above the filtering device 13 , be at least partially made of elastic material . the filtering device can be made of porous or fibrous material such as cellulose . it can also be of hydrophobic character , e . g ., comprise or consist of siliconized cellulose , in order to preferably let through hydrophobic fluids , such as organic solvents such as chcl 3 ( chloroform ). the device also has a hole at 14 and carries a partition wall at 15 . reagents can be present at 5 in some of the ways that are described with respect to the embodiments of fig1 through 3 . measuring and testing solutions and transport thereof to the tube - shaped part 5 can be made as described above with respect to the embodiment of fig1 . filtering of the solution can be facilitated by compression of the section of the tube - shaped part 4 that is on the same side of the filter as the reaction compartment , and then , with the hole 14 closed by a finger , by allowing the walls to return to their original position by elasticity , whereupon an underpressure or vacuum is formed that suctions the solution through the filter 13 . the embodiments of fig3 and 4 are particularly advantageous because the measuring compartments 1 can accommodate larger volumes of solution than is possible with the embodiments of fig1 and 2 . a device according to fig2 where the reaction compartment 5 contains an ampoule with 0 . 3 ml of 10 % trichloroacetic acid in water , and with a measuring compartment 1 for measuring out 0 . 15 ml of solution , is used in the following manner : the measuring compartment is dipped into a beaker containing urine . the measured urine sample is transferred to the reaction compartment by turning the device so that the measuring compartment is directly above the reaction compartment . simultaneously , one compresses with the fingers of one hand , the ampoule or the ampoules 11 and 12 , which are thereby emptied into the reaction compartment , whereupon the reagents are mixed with the urine . urine samples that have , with quantitative methods , been shown to contain more than 0 . 2 g of protein / l , give precipitates that increase with increasing protein concentration . a device according to fig2 where the reaction compartment 5 contains an ampoule 12 with a reagent consisting of 1 / 6 of a tablet of clinitest ® manufactured by the ames co ., elkhart , in , usa or essentially the same amount of a dry powder mixture with the corresponding function consisting of cupper sulfate , sodium sulfate , trisodium citrate , citric acid , sodium carbonate and sodium hydroxide . another ampoule 11 contained 0 . 1 ml of water . the measuring compartment 1 was made to measure 0 . 025 ml of liquid . the device was used as in example 1 . in this way , glucose in urine could be detected provided the concentration was above 0 . 5 %. at glucose concentrations between 0 . 5 and 1 %, a green color was obtained . if the glucose concentration was above 2 %, a yellow - brown color was obtained . at glucose concentrations above 4 %, a yellow concentration was obtained . thus it was possible to make a determination of the glucose concentration in a simple way . although the invention has been described above with reference to specific preferred embodiments thereof , it will be evident to persons ordinarily skilled in the art that changes and modifications may be made to the invention without departing from the scope of the invention defined by the claims .
