The technical scheme adopted by the utility model in order to further solve the technical problem is: the lower end of the described suction pipe is provided with a collection pipe, and the diameter of the collection pipe is smaller than that of the pipette. A fixing plate is arranged above the airbag, a mounting plate is fixedly arranged on the suction pipe, at least two connecting rods are hinged at the lower part of the fixing plate, and several transparent chutes are set on the mounting plate, and the number of chutes is the same as that of the connecting rods , the connecting rod is located in the corresponding chute and can slide along the chute, the first limit block is set in the middle of the connecting rod, the second limit block is set in the lower part of the connecting rod, and the mounting plate is located between the first limit block and the second limit block Between, the widths of the first limiting block and the second limiting block are greater than the width of the chute.

The beneficial effects of the utility model are: the utility model can pinch the air bag and squeeze out the gas inside before collecting, and then insert the lower end of the suction tube into the container for holding urine and watery stool, and then loosen The air bag makes the liquid flow into the suction pipe under the action of negative pressure. When the liquid rises to the containing cavity, the floating ball floats up. When the floating ball floats to the upper part of the containing cavity, the floating ball stops floating and closes the suction tube. Under the action, it is stored in the accommodation cavity and the suction tube under the floating ball. By limiting the volume between the suction end of the suction tube and the storage cavity and the volume of the storage cavity, and then subtracting the volume of the floating ball, the urine, water Quantitative collection of stool samples. The utility model can complete the collection of urine and watery feces with one hand only by pinching and squeezing and releasing the air bag, the collection time is short, the operation is convenient, and at the same time, the collection volume of urine and watery feces can be precisely limited, Avoid affecting the test results.

Detailed ways

The urine and water sample stool quantitative collector, as shown in Figure 1, includes an airbag 1, the lower part of the airbag 1 is connected to a suction tube 2, a spherical housing 3 is arranged on the suction tube 2, and a spherical housing chamber is provided in the housing 3 4. The upper and lower ends of the accommodation chamber 4 communicate with the pipette 2 respectively. The diameter of the chamber 4 is larger than the diameter of the pipette 2. A floating ball 5 is arranged in the chamber 4. The diameter of the float 5 is larger than the diameter of the pipette 2. . This structure can pinch the airbag 1 and extrude the gas in it before collecting, then insert the lower end of the suction tube 2 into the container for holding urine and watery stool, release the airbag 1, and make the liquid in the container Under the action of negative pressure, it flows into the suction pipe 2. When the liquid rises into the housing chamber 4, the floating ball 5 floats up. When the floating ball 5 floats up to the upper part of the housing chamber 4, the floating ball 5 stops floating and closes the suction pipe 2. The liquid is stored in the chamber 4 and the suction pipe 2 under the floating ball 5 under the action of air pressure. By defining the volume between the suction end of the suction pipe 2 and the chamber 4 and the volume of the chamber 4, the float ball is subtracted. With a volume of 5, the quantitative collection of urine and water samples can be realized. This structure can complete the collection of urine and watery stools with one hand only by pinching, squeezing and releasing the airbag 1, the collection time is short, the operation is convenient, and at the same time, the collection volume of urine and watery stools can be precisely limited , so as not to affect the test results.

As shown in FIG. 1 , a collection tube 6 is provided at the lower end of the suction tube 2 , and the diameter of the collection tube 6 is smaller than that of the suction tube 2 . This structure can collect urine and water samples through the small-diameter collection tube 6, and the collection tube 6 can prevent large particle residues from entering the pipette 2, preventing large particle residues from affecting the test results.

Due to limited laboratory equipment, urine and water samples need to wait for testing after the quantitative collection is completed, and because the airbag 1 cannot be squeezed, the outer wall of the suction tube 2 is attached to the outer wall of the urine and water samples, which is easy to contaminate objects in contact with it , therefore, is not convenient for storage. As shown in Figure 2, a fixed plate 7 is arranged above the airbag 1, a mounting plate 8 is fixedly arranged on the liquid suction pipe 2, at least two connecting rods 9 are hinged at the bottom of the fixed plate 7, and several transparent openings are set on the mounting plate 8. chute 10, the number of chute 10 is the same as the number of connecting rods 9, the connecting rod 9 is located in the corresponding chute 10 and can slide along the chute 10, the middle part of the connecting rod 9 is provided with a first stopper 11, the connecting rod 9 The lower part is provided with a second limiting block 12, the mounting plate 8 is located between the first limiting block 11 and the second limiting block 12, and the width of the first limiting block 11 and the second limiting block 12 is greater than the width of the chute 10 . This structure can be connected with other items through the fixing plate 7, and the air bag 1 and the suction tube 2 can be suspended to prevent the air bag 1 from being squeezed and the suction tube 2 from contaminating other items. This structure can also push the fixed plate 7 when collecting urine or water samples, so that the fixed plate 7 can squeeze the air bag 1, thereby completing the sampling. This structure is convenient for storing the air bag 1 and the liquid suction tube 2 .
