By blowing inert gas internally, the powder adsorbed on the containing membrane is blown off without contaminating the medicine, thereby ensuring that the ratio of the medicine raw materials meets the standard.

[0016] 4. The drug and urine of the device do not react directly. Both the drug and urine need to be transferred to the solution tank in the middle before they can react to ensure that both solutions will not be contaminated. In addition, the drug will be transferred through the port device, so the test drug and urine will not flow back into the drug barrel, causing the problem of drug and urine mixing in the drug barrel.

[0031] The reaction container 2 comprises a sub-shell 21 , a color developing device 6 is fixedly connected to the left side of the outer surface of the sub-shell 21 , and liquid pumping devices 5 are symmetrically arranged on the front and rear sides of the inner wall of the sub-shell 21 .

[0032] The left side of the color developing device 6 is fixedly connected to the right side of the outer surface of the double-position protective shell 11, the number of test tube containers 3 is two, the bottom end of the long tube 31 is fixedly connected to the bottom of the inner wall of the double-position protective shell 11, and the outer surface of the threaded rotating cylinder 41 is threadedly connected to the inner wall of the threaded top cover 12 through a thread.

[0033] Before using the device to test the patient's urine, it is necessary to prepare the test reagent first. At this time, the operator rotates the friction sleeves 43 on both sides clockwise to make the threaded rotating cylinder 41 spiral downward around the threaded top cover 12, and then inserts the conical insertion rod 410 at the bottom of the sliding cylinder 47 to pierce the containing membrane 33 along the dotted line, so that the 0.2g sodium dithionite powder in the containing membrane 33 is dropped into the medicine cylinder 34 at the bottom, and mixed with the 2.1ml 5% sodium bicarbonate sterile solution inside and reacts.

[0034] After the medicines are mixed, the operator presses down the pressure cover 44 from the outside. At this time, the auxiliary slide bar 42 slides down along the inner wall of the threaded rotating cylinder 41, pushing the compression hose 49 to press down the conical plug rod 410. Then the compression hose 49 is compressed, and the gas inside the compression hose 49 is squeezed into the inside of the hollow extension rod 45 and sprayed out from the groove of the hollow extension rod 45. Then the gas is sprayed through the oblique groove of the plug-in slide barrel 47 to the side close to the storage membrane 33, blowing the sodium disulfite powder remaining in the damaged storage membrane 33 into the solution below.

[0035] After the threaded rotating cylinder 41 slides down to the bottom position, the bottom end of the plug-in slide cylinder 47 will close the top of the medicine cylinder 34. At this time, the device is shaken to fully mix the sterile sodium bicarbonate solution and the sodium disulfite powder. After the preparation of the medicine is completed, the medicine is extracted through the reaction container 2, mixed with the extracted urine for reaction, and then the detection work is carried out.

[0036] Example 2, please refer to Figure 1-Figure 8 The present invention provides a technical solution: on the basis of the first embodiment, the liquid pumping device 5 comprises a clustering plate 51, and the lower surface of the clustering plate 51 is symmetrically provided with a liquid pumping piston rod 52, the bottom of the outer surface of the liquid pumping piston rod 52 is slidably connected to a guide inner cylinder 53, the bottom of the inner wall of the guide inner cylinder 53 is slidably connected to a bottom end sliding plug 55, and the top of the bottom end sliding plug 55 is fixedly connected to a return spring 54. There are two liquid pumping piston rods 52, the top of the liquid pumping piston rod 52 is fixedly connected to the inner cavity of the clustering plate 51, the outer surface of the liquid pumping piston rod 52 is slidably connected to the top of the inner wall of the auxiliary housing 21, the bottom end of the guide inner cylinder 53 extends to the outside of the auxiliary housing 21, and the outer surface of the guide inner cylinder 53 is fixedly connected to the inner cavity of the auxiliary housing 21, and the top of the return spring 54 is fixedly connected to the middle part of the inner wall of the guide inner cylinder 53.

[0037] The color development device 6 includes a solution box 61, a color development plate 62 is symmetrically arranged on the front and rear sides of the inner cavity of the solution box 61, a port device 7 is symmetrically arranged on the left side of the inner cavity of the solution box 61, a middle partition 64 is fixedly connected to the middle of the inner cavity of the solution box 61, and a bending connecting pipe 63 is symmetrically arranged on the right side of the inner cavity of the solution box 61. There are two bending connecting pipes 63, the bottom end of which extends to the outside of the solution box 61, and the bottom end of the bending connecting pipe 63 is fixedly connected to the inner cavity of the guide inner cylinder 53, and the left side of the outer surface of the solution box 61 is fixedly connected to the right side of the outer surface of the double-position protective shell 11.

[0038] The port device 7 includes a horizontal push rod 72, the left end of which is fixedly connected to a sealing plate 73, the right side of the inner cavity of the sealing plate 73 is adsorbed with a connecting tube shell 71 through a magnetic ring 76, the right end of the horizontal push rod 72 is fixedly connected to a force-bearing push plate 74, and the left side of the outer surface of the force-bearing push plate 74 is fixedly connected to a compression jacket 75. There are two port devices 7, the left end of the compression jacket 75 is fixedly connected to the left side of the inner wall of the solution box 61, the right end of the connecting tube shell 71 is fixedly connected to the left side of the inner cavity of the solution box 61 through a through hole, and the left end of the connecting tube shell 71 extends to the inside of the medicine barrel 34.

[0039] When the reaction container 2 is working, the operator first presses the clustering plate 51 and slides the liquid extraction piston rod 52 down along the inner wall of the guide inner tube 53. Since the bottom sliding plug 55 will block the bottom end opening of the guide inner tube 53, the gas inside the guide inner tube 53 will enter the solution box 61 through the bent connecting tube 63. The pressure inside the solution box 61 increases, pushing the force-bearing push plate 74 to the left, and the horizontal push rod 72 slides to the left. The compression sleeve 75 is compressed, and the sealing plate 73 slides to the left and separates from the connecting tube shell 71. The medicine enters the connecting tube shell 71 and the compression sleeve 75 through the opening opened at the left end of the connecting tube shell 71 to carry out the transfer of the medicine.

[0040] The bottom end of the guide inner cylinder 53 is aligned with the urine sample, and the operator pulls the clustering plate 51 upward. The bottom sliding plug 55 slides upward due to the pressure, opening the bottom opening of the guide inner cylinder 53. At this time, the guide inner cylinder 53 draws the urine at the bottom into the interior while decompressing the interior of the solution tank 61 through the bent connecting tube 63. At this time, the force-bearing push plate 74 slides to the right, and the medicine inside the connecting tube shell 71 and the compression jacket 75 enters the solution tank 61 through the nozzle of the compression jacket 75, reacts with the color developing plate 62, and the color developing plate 62 turns green.

[0041] After extracting urine, the bottom end of the guiding inner tube 53 is blocked, and the operator presses down the clustering plate 51. At this time, the urine inside the guiding inner tube 53 will enter the solution box 61 through the bent connecting tube 63 to react with the reagent, and then wait for a few seconds for colorimetry to complete the detection work.

[0042] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
