The small circular opening at the end of the slide rail can prevent the drainage device 7 from sliding out of the placing groove 5 due to mistaken touch. In addition, when the sliding rail handle 8 is used, the sliding rail handle is only required to be pressed downwards to be separated from the round small opening, and then the sliding rail handle is slid out from the sliding rail 6.

Preferably, there is the hole in bowl cover 4 center department, and the hole has the external screw thread interface that extends downwards to with gathering cup 3 through threaded connection inside main cup 2. The specification of the collecting cup 3 is consistent, the number of scales and the thread position are kept unchanged, and the number of threads is also kept unchanged, so that the number of scales is kept unchanged at the relative position of the main cup when the collecting cup 3 is clamped to the main cup 2. The bearing 9 is positioned at the central hole of the cup cover 4 and connected with the flow diverter 7, and can keep the flow diverter 7 and the cup cover 4 together when the collecting cup 3 rotates relative to the cup cover 4. Meanwhile, the drainage device 7 extends into the collection cup 3 through the hole in the center of the cup cover 4, so that the liquid sample is isolated from other parts, and the pollution-free state of the liquid sample is ensured.

Preferably, the bearing 9 may be a rotational bearing comprising an inner ring, an outer ring (or balls), wherein the outer ring is embedded in a hole at the center of the cup cover 4, so that the bearing 9 is fixed in the cup cover 4, and the inner ring is provided with a bayonet structure which enables the flow diverter 7 to be detachably located at the hole at the center of the cup cover 4. The drainage device 7 can be fixed on the inner ring through the self buckle structure, and is convenient to take out from the central hole of the cup cover 4 for replacement or disinfection and cleaning.

Preferably, a slide rail 6 which is opened towards the top surface of the cup cover is communicated with a radially extending placing groove 5 formed between interlayer layers in the cup cover. The drainage device 7 can be driven by the slide rail handle 8 to stop in the placing groove 5 in a mode that the drainage device 7 cannot rotate at a certain position in the following mode when the cup cover 4 moves along the radial direction: the arc-shaped sliding rail 6 is located at the radial outer side of the placing groove 5 and only forms a partial arc shape, and the arc-shaped tail end of the arc-shaped sliding rail forms a stopping limiting part of the moving distance of the drainage device 7. This enables the flow director 7 to be protected from damage due to excessive rotation.

Preferably, the magnifying glass 10 is embedded in the cup wall of the main cup 2, and the magnifying glass 10 is a rectangular observation window, and is located at one third of the main cup and aligned with the scale number position on the collecting cup 3. Due to the consistency of the specifications of the collecting cups 3, the magnifying glass surfaces 10 on all the main cup bodies 2 can be matched with each collecting cup 3, and the assembly and the use of the collecting cups are convenient. Preferably, the magnifying glass 10 may have a small protrusion outward from the cup wall, so as to function as a small handle on the premise of not obstructing observation, so as to prevent the main cup body 2 from sliding off from the hand of the patient, and make the holding more stable.

The working principle of the utility model is as follows:

with drainage device 7 through its self buckle structure, circle in with and make drainage device 7 detachably be located the bayonet structure block of 4 central holes departments of bowl cover, gather cup 3 and pass through threaded connection on bowl cover 4, install bowl cover 4 on main cup 2 again, begin to use. Drainage ware 7 is driven it by slide rail handle 8 and is accomodate 5 depths of standing groove in bowl cover 4 inside from airtight laminating ground and rotate to 5 entrances of standing groove and take out, and drainage ware 7 expands based on elasticity, enlarges its collection mouth bore, begins to collect patient's liquid sample. After the collection is finished, the volume of the liquid sample in the collecting cup 3 is observed through the amplifying mirror surface 10 embedded on the cup wall of the main cup body 2 in the circumferential direction, and the volume is ensured to be enough for detection. The first section of the drainage device 7, which is located at the cup cover 4, is accommodated in the placing groove 5 formed by the double-layer structure of the cup cover 4 in a clamping manner based on the reduction of the compression space, the drainage device 7 is gradually tightened and clamped due to the wedge-shaped compression space in the placing groove 5, and finally the fluid connection located at the center of the cup cover 4 is closed due to extrusion, so that the use process is finished.
