Detailed Description

Referring to fig. 1-6, a specific configuration of the present invention is reflected. The middle section urine sampler comprises a urine receiving cup 1, a bottom through hole 11 of the urine receiving cup 1 is communicated with a bottom cavity 8 below the urine receiving cup 1, an overflow hole 2 is formed in the side wall of the urine receiving cup 1, and a high-position urine overflow hole pipe 10 is arranged on the opposite side of the overflow hole 2. The overflowing tail end urine can be conveniently and timely discharged. The overflow hole 2 is connected with a cap of a storage tube 13 for midstream urine through an overflow tube 3 which inclines downwards, the tail end of the overflow tube 3 is provided with a connecting convex tube 4, and three exhaust slits 401 are uniformly distributed on the circumference of the outer wall of the connecting convex tube 4.

The port of the connecting convex pipe 4 is provided with a sealing element 5 made of plastic or similar materials: the cylinder 501 of the sealing element 5 is nested in the port of the connecting convex tube 4, three cracks 503 which are evenly distributed on the circumference are preset on the bottom end surface 502 of the cylinder 501, and the three cracks 503 are intersected at the center of the bottom end surface 502 of the cylinder 501. A cylindrical through hole 15 described below is inserted into a port of the connecting boss 4 through a slit 503, and a bottom end face 502 of the cylinder divided by the three slits 503 is ruptured therewith and seals a connecting face between the cylindrical through hole 15 and the port. Can have obvious damping feeling when inserted.

The cap comprises a convex cavity 18 nested in the port of the storage pipe 13, a cylindrical through hole 15 is arranged in the center of the bottom surface of the convex cavity 18, and four exhaust holes 17 which are uniformly distributed circumferentially are arranged on the bottom surface of the convex cavity beside the cylindrical through hole 15. When overflow pipe 3 is connected with the cap: the connecting convex pipe 4 is nested in the convex cavity 18, and the cylindrical through hole 15 is nested in the connecting convex pipe 4 through a sealing element 5. Thereby realize both's zonulae occludens and effectively reduce the phenomenon that the urine was revealed, simultaneously, when the urine flowed into storage tube 13 from cylindricality through-hole 15 in, the air in storage tube 13 was discharged to the external world from exhaust hole 17, exhaust slit 401 in proper order to ensure that the urine smoothly entered into storage tube 13 without hindrance.

The periphery of the convex cavity 18 of the cap is provided with a threaded outer sleeve 16, and the internal thread 19 of the threaded outer sleeve 16 is arranged corresponding to the external thread 14 on the storage pipe 14. The top end face of the cap is provided with an openable end cover 20, and the bottom end of the storage pipe 14 is provided with a sediment blind hole 12. Is convenient for storage and inspection.

A floating ball 6 is placed in a bottom cavity 8 of the urine receiving cup 1, and the size of the floating ball 6 corresponds to that of the bottom through hole 11, so that the bottom through hole 11 can be sealed when the floating ball 6 floats.

The top of bottom chamber 8 centers on bottom through-hole 11 distributes ten guide strips 9, bottom chamber 8 is cylindrical cavity, bottom through-hole 11 is located the central centre of a circle position of the top surface of bottom chamber 8, and ten guide strips 9 are followed the radial circumference evenly distributed of bottom chamber 8 top surface. The guide strip 9 is of a slope structure, one end of the guide strip 9 close to the side wall of the bottom cavity is a higher end 901, and one end close to the bottom through hole 11 is a lower end 902. The urine at the front section enters the bottom cavity 8, the floating ball 6 floats upwards, and under the oblique extrusion guidance of the slope-shaped guide strips 9 at the periphery, the resultant force of the buoyancy and the extrusion force enables the floating ball 6 to move only to the middle bottom through hole 11 until the bottom through hole 11 is sealed. In this case, the bottom end opening of the bottom cavity 8 is provided with an openable transparent bottom cover 7. The urine can be conveniently observed and poured out.

As shown in figure 6, the storage tube 13 and overflow tube 3, which are connected together by a cap, can be used as a handle for a mid-stream urine sampler due to the tight and secure connection. When in use, a user holds the handle which is inclined downwards, and can naturally and smoothly keep the urine receiving cup basically horizontal so as to facilitate the work of the floating ball; the high-position urine overflow hole pipe 10 on the opposite side of the handle can conveniently face the urinal, and after the front section urine is filled in the bottom cavity 8, the middle section urine is filled in the storage pipe 13 through the overflow hole 2 and the overflow pipe 3 in sequence; then the urine receiving cup 1 is filled and discharged from the high-position urine overflow hole pipe 10 into the urinal. The structure is simplified due to multiple purposes; no other operation is needed before the urination is finished, and the use is convenient and sanitary.
