Description

Technical Field

[0001] The utility model relates to the technical field of extracting organic acids adsorbed on urine filter paper, in particular to a device for extracting organic acids on urine filter paper. Background Art

[0002] Human urine contains organic acids (also known as uric acid). Excessive levels of organic acids will not only affect human health and cause physiological diseases, but also indicate certain genetic metabolic diseases. Urine filter paper is used as a carrier for urine samples. After the urine filter paper is filled with urine and dried, it is more convenient for sample storage and transportation than liquid urine samples. However, urine filter paper is not suitable for subsequent urine organic acid testing. The organic acids in the urine filter paper must be extracted in advance before the content of organic acids in the urine can be detected by the testing instrument.

[0003] A laboratory uses Figure 1~Figure 3 The extraction device shown is used to extract organic acids in urine filter paper, and the extraction device includes a cylindrical tube 2 fixedly mounted on a pad 1, a disc 3 fixedly mounted on the inner bottom wall of the cylindrical tube 2, a plurality of liquid holes 4 are opened in the disc 3, a filter screen 5 is fixedly mounted on the top surface of the disc 3, a bracket 6 is fixedly mounted on the top surface of the pad 1, a lower piezoelectric cylinder 7 is fixedly mounted on the top of the bracket 6, a piston rod of the lower piezoelectric cylinder 7 penetrates the bracket 6 downward, and a pressure plate 8 located directly above the cylindrical tube 2 is fixedly mounted on the extended end; a drain valve 9 is fixedly mounted at the bottom of the cylindrical tube 2.

[0004] The working method of the extraction device is:

[0005] S1. A worker takes out a urine filter paper and cuts the urine filter paper into multiple pieces to obtain multiple small urine filter paper pieces;

[0006] S2, the worker puts the urine filter paper onto the filter screen 5 from top to bottom, and the direction of addition is as follows: Figure 1 As shown by the middle arrow, at this time, the urine filter paper is just supported on the filter screen 5; then a certain amount of extraction liquid is injected into the cylindrical barrel 2 so that the extraction liquid submerges the urine filter paper, and at this time, the organic acid on the urine filter paper is extracted into the extraction liquid. After a period of rest, the organic acid, the extraction liquid and the urine are separated into layers, and the organic acid layer is located above the extraction layer and the urine layer;

[0007] S3. The worker uses a suction tube to extract the organic acid from the top layer. After extraction, the organic acid is sent to a detection instrument for detection, and the content of the organic acid is detected by the detection instrument;

[0008] S4, the treatment of the extract and urine in the cylindrical tube 2, the specific operation steps are:

[0009] S41, when the test is completed, the worker places a collection box just below the drain valve 9, opens the drain valve 9, and the extract and urine in the cylindrical tube 2 are discharged into the collection box in sequence through the mesh of the filter 5, the liquid hole 4, and the drain valve 9;

[0010] S42, control the piston rod of the lower pressure electric cylinder 7 to extend downward, the piston rod drives the pressing plate 8 to enter the cylindrical tube 2, and the pressing plate 8 presses the urine filter paper downward, such as Figure 4 As shown, the pressing plate 8 squeezes out the residual extract and urine on the urine filter paper, and the squeezed residual extract and urine are sequentially discharged into the collection box through the filter screen 5, the liquid hole 4, and the drain valve 9;

[0011] S43, control the piston rod of the lower piezoelectric cylinder 7 to retract upward, and the piston rod drives the pressing plate 8 to move upward, so that the pressing plate 8 is withdrawn from the cylindrical tube 2; then the worker takes the urine filter paper off the filter screen 5, and after taking it away, the worker throws the urine filter paper into the garbage bag, thereby preparing for the subsequent extraction operation.

[0012] However, although this extraction device can extract organic acids in urine, it still has the following technical defects in actual operation:

[0013] In step S42, since the urine filter paper is left inside the cylindrical barrel 2, the operating space for taking out the urine filter paper is limited, which not only increases the work intensity of the workers, but also increases the time for taking out the urine filter paper, thereby reducing the extraction efficiency of the subsequent batches of urine filter paper. Therefore, an extraction device that reduces the work intensity of the workers and improves the extraction efficiency of the subsequent batches of urine filter paper is urgently needed.
