Preferably, a handle is connected to the middle section urine outflow pipe corresponding to the position above the plug, and a first finger groove penetrating through the handle is formed in the handle. Medical personnel's finger stretches into first finger groove, then medical personnel's application of force so that the finger offsets with first finger groove upper groove wall to make handle rebound, thereby drive stopper rebound, finally make stopper and second through-hole break away from mutually, it is more convenient to enable the switching that first collecting chamber and external world blocked or communicate, so that medical personnel's sample is more convenient.

Preferably, a downwardly extending guide pipe is connected to the middle section urine outflow pipe corresponding to the second through hole, the second through hole penetrates through the guide pipe from top to bottom, and a collection container is detachably fixed to the lower end of the guide pipe. The medical staff can hold the guide tube by hand to prevent the contact part of the second through hole and the plug from moving upwards synchronously along with the plug when the plug is taken out; wherein, can replace handheld middle section urine outflow pipe through the mode of handheld stand pipe, when middle section urine outflow pipe was made by transparent material, the medical personnel of being convenient for observed the position of stopper to it is more convenient to make medical personnel take a sample. Wherein, the collection container is arranged to facilitate the transfer of midstream urine without the need for medical personnel to carry a cup for containing midstream urine. Wherein, the collecting container can adopt the fixed mode of buckle or screw thread to dismantle fixedly with the stand pipe.

Preferably, the outer wall of the guide pipe is provided with two second finger grooves, and the two second finger grooves are respectively positioned on one of two opposite sides of the guide pipe. When the plug is taken out, the fingers of the medical staff extend into the second finger grooves, so that the medical staff can apply force to the guide tube to fix the upper position and the lower position of the guide tube, and the plug and the guide tube can be separated conveniently; meanwhile, when the collecting container is taken out, the collecting container and the guide pipe can be conveniently separated, so that the medical staff can take samples more conveniently.

Preferably, the first through hole extends gradually downwards from inside to outside. The first through hole gradually extends downwards from inside to outside, and can play a role in guiding middle-section urine so as to facilitate the middle-section urine to move to the outside.

Preferably, a funnel is arranged above the first liquid collecting kettle, an opening at the lower part of the funnel is positioned in the first liquid collecting cavity, a rear side wall at the upper part of the funnel extends towards the rear side, so that the length of the rear side wall at the upper part of the funnel along the front-rear direction is greater than that of the front side wall at the upper part of the funnel along the front-rear direction, and the rear side wall at the lower part of the funnel extends towards the front side to form a flow guide surface. The funnel can avoid patient's urine and the contact of the inner wall lower extreme of first album of liquid kettle, avoids anterior segment urine to splash to the inside wall of first album of liquid kettle for during anterior segment urine can not sneak into middle section urine, improve the accuracy of the urine examination result of middle section urine. The rear side wall of the upper end of the funnel extends towards the rear side, so that urine can easily enter the funnel and can not splash to the outer side of the funnel. The lower extreme of funnel extends formation water conservancy diversion face to the front side to make the urine flow down along the lateral wall in first liquid collecting cavity, thereby the urine can not bump the bottom in first liquid collecting cavity and avoid producing the noise.

Preferably, the bottom of the first liquid collecting cavity is of a structure with high periphery and low middle part, the upper end of the second liquid collecting kettle is connected with the middle part of the bottom of the first liquid collecting kettle, and the inner diameter of an opening at the upper end of the second liquid collecting cavity is gradually reduced from bottom to top. The chamber bottom of first collecting chamber is the structure that high centre is low all around to make anterior segment urine get into the second collecting chamber better under the action of gravity, make the difficult attached to in the first collecting chamber bottom of anterior segment urine, avoid anterior segment urine to sneak into the accuracy of urine examination result in order to improve the patient in the middle section urine as far as possible. The inner diameter of the opening at the upper end of the second liquid collecting cavity is gradually reduced from bottom to top, and the floating ball can be guided, so that the floating ball can block the opening at the upper end of the second liquid collecting cavity.

The urine sampler has the advantages of convenience in sampling, capability of avoiding splashing of urine during sampling, capability of avoiding the middle section urine from being mixed with the front section urine or the rear section urine as far as possible, and capability of improving the urine detection accuracy.
