Regarding the use of the present embodiment:
since the valve core 73 of the urine cup b is normally closed by the acting force of the second spring 74, when a urine test person discharges urine into the cup 7, the urine does not leak out from the liquid outlet 71;
after the tested person discharges urine into the cup body 7 of the urine cup b, the cup cover 8 is covered, and then the urine cup is delivered to medical staff;
after receiving the urine cup b, medical staff needs to sample urine in the urine cup b onto test paper, and then test and analyze the test paper through a urine analyzer; the operation rack c is not needed when the number of the urine cups b is small, but when the number of the urine cups b is large, the time for leading the urine in the urine cups b into the urine test tube a one by one is relatively spent, so that the operation rack c can be used for improving the efficiency;
the sampling flow is as follows:
a) When a plurality of urine cups b are sampled, the operation rack c is needed, and the sampling process is as follows:
firstly, preparing a plurality of urine test tubes a, and unscrewing the cover 3 of each urine test tube a; then placing each urine test tube b into each fixed station of the operation rack c, when placing, arranging the gear ring of the outer wall of the rotator 22 of the urine test tube a towards the gear rack 931 of the operation rack c, then clamping the top of the shell 21 of the urine test tube a into the clamping groove 94 of the operation rack c, and then forcefully pushing the tube body 1 of the urine test tube a to clamp the tube body 1 into the arc-shaped clamping surface 921 of the clamping piece 92, wherein after clamping, the gear ring of the rotator 22 is meshed with the gear rack 931; then, each urine cup b is placed on the top surface 913 of the frame 91 and corresponds to each urine test tube a below one by one, when the urine cup b is placed, the first convex ring 75 and the second convex ring 76 at the bottom of the cup 7 of the urine cup b are required to be respectively clamped in the annular groove 95 of the frame 91 and the annular surface 213 of the urine test tube b, so that the purpose of positioning is achieved, and urine is ensured to enter the urine test tube a below when leaking from the liquid outlet 71 of the urine cup b and not overflow outwards; wherein, the ring surface 213 not only plays a role in positioning, but also plays a role in preventing urine from overflowing, and the state of the urine cup b after being placed can be seen in fig. 11 and 12;
After each urine cup b is placed, the dial wheel 932 of the operating rack c is rotated by hand to rotate in a specific direction, when the dial wheel 932 rotates, the second gear 934 and the first gear 933 are sequentially driven to rotate, the rotation of the first gear 933 drives the rack 931 to move horizontally, and as the rotating bodies 22 of each urine test tube a are meshed with the rack 931 through the gear ring, each rotating body 22 rotates along with the horizontal movement of the rack 931; since the plug 23 is screwed into the rotor 22, the plug 23 moves upward in the axial direction when the rotor 22 rotates; as the plunger 23 moves up, the plunger 23 gradually moves to contact with the valve core 73 of the urine cup b, and then as the rotator 22 continues to rotate, the plunger 23 continues to move up and pushes the valve core 73 to move up, so that the liquid outlet hole 71 is opened; therefore, urine in the cup 7 flows through the strip-shaped hole 721 to the liquid outlet 71, then flows out of the liquid outlet 71 into the tapered hole 211a of the vertical hole 211 below, then flows down along the fluid passage 233 formed in the lower portion of the plug 23, and then flows out of the fluid passage 233 into the tube 1; along with the gradual increase of urine in the tube body 1, the test paper 25 is soaked in the urine, when the liquid level of the urine in the tube body 1 reaches a certain height, the poking wheel 932 of the operating rack c is reversely rotated by hands to drive the rack 932 to reversely rotate, so that the rotating body 22 of each urine test tube a reversely rotates, in the process, the plug 23 moves downwards, the poking wheel 932 stops rotating until the plug 23 moves downwards to the lowest point, at the moment, the valve core 73 of the urine cup b closes the liquid outlet hole 71 again under the action of the second spring 74, so that the urine in the cup body 7 stops entering the tube body 1, and at the same time, the outer wall of the conical body 232 of the plug 23 is tightly attached to the conical hole 211a of the vertical hole 211, so that the urine in the tube body 1 can be sealed, and the peculiar smell of the urine cannot volatilize;
After waiting for a certain time, the test paper 25 finishes sample soaking, each urine cup b and each urine test tube a are taken down from the operation rack c, and then the test paper 25 in each urine test tube a is taken out in sequence, and the taking out process is as follows: the seal plate 234 on the top of the plug 23 of the urine test tube a is unscrewed by hand, then the head 241 of the test paper attaching rod 24 is clamped by forceps and lifted upwards, the test paper attaching rod 24 can be taken out (see fig. 13), and then the test paper 25 is torn off the rod body 242; when the test paper attaching rod 24 is taken out from the cavity 231 of the plug 23, the silica gel sheet 235 under the plug 23 seals the opening at the bottom of the cavity 233 (see fig. 13), so that the odor of urine in the tube 1 can be prevented from volatilizing;
then, the test paper 25 taken out from each urine test tube a is put into a urine analyzer for test analysis;
in the above steps, after each urine cup b is placed on the top surface 913 of the frame 91, the top of the urine cup b may be pressed by a pressing plate (not shown) or other components to prevent the plunger 23 from pushing the valve core 73 of the urine cup b upward.
