Detailed Description

The following describes in further detail embodiments of the present invention with reference to the accompanying drawings.

As shown in fig. 1 to 5, the invention comprises a transverse main pipe 1, the right end of the main pipe 1 is sealed, and the left end of the main pipe 1 is provided with a urine receiving hopper 2 with a big top and a small bottom; the main pipeline 1 is connected with three vertical joints 3, a front test tube 4 is inserted on the joint 3 on the left side, and a piston rod 6 are installed in the front test tube 4; a middle test tube 5 is inserted on the middle joint 3;

a baffle 7 capable of moving left and right is installed inside the main pipeline 1, the baffle 7 can reset right, a through hole 8 is formed in the baffle 7, and the through hole 8 can respectively correspond to the three connectors 3 in sequence by moving the baffle 7 three times in the right direction;

a vertical plate 9 is arranged at the right end of the baffle 7, and a left pin 10 and a right pin 10 which penetrate through the main pipeline 1 are arranged on the main pipeline 1; the pins 10 can block the vertical plates 9 from moving rightwards; the two pins 10 are sleeved with air bags 11 respectively, the two air bags 11 are connected with a reaction box 13 through air pipes 12 respectively, effervescent powder 14 is arranged in the reaction box 13, overflow pipes 15 are arranged on the front test tube 4 and the middle test tube 5 respectively, and the overflow pipes 15 are connected with the two reaction boxes 13 respectively; wherein the front test tube 4 controls the pin 10 on the left side, and the middle test tube 5 controls the pin 10 on the right side; the effervescent powder 14 can generate gas to move the pin 10 upward when it encounters liquid.

In order to realize the installation and the reset of the pin 10, a fixed block 16 is installed on the main pipeline 1, and the pin 10 penetrates through the fixed block 16.

In order to prevent the gas from being guided into the test tube, the overflow tube 15 is provided at one end of the reaction chamber 13 with a rubber gasket 17, and one side of the rubber gasket 17 is fixed to the inside of the reaction chamber 13.

In order to discharge urine in the reaction box 13, a liquid discharge pipe 18 is connected to the bottom of the reaction box 13, and a rubber stopper 19 is mounted at the upper end of the liquid discharge pipe 18.

In order to avoid contamination, the rightmost joint 3 of the three joints 3 is extended in length, and the lower end of the drain pipe 18 of each reaction tank 13 is connected to the rightmost joint 3.

In order to control the capacity of the front test tube 4 conveniently, the front test tube 4 is in a vertically through structure, and the lower end of the piston rod 6 penetrates through the lower end of the front test tube 4.

In order to realize the rightward resetting of the baffle 7, a guide rod 20 is inserted at the right end of the main pipeline 1, the left end of the guide rod 20 is fixedly connected with the vertical plate 9, a pressure spring 21 is sleeved on the guide rod 20, one end of the pressure spring 21 is fixed at the right end of the guide rod 20, and the other end of the pressure spring 21 is fixed at the right end of the main pipeline 1.

For deodorizing and gas generation, the effervescent powder 14 contains a fragrance, sodium bicarbonate and citric acid.

When the invention is used, the front test tube 4 and the middle test tube 5 are installed; the guide rod 20 is pushed to the left to the maximum extent, and the vertical plate 9 is blocked by the pin 10 on the left side; the through hole 8 on the baffle 7 corresponds to the joint 3 at the upper end of the front test tube 4; i.e. the state shown in fig. 2. Before use, both the left and right pins 10 are in a state of being pressed down.

During the sample, at first according to the wish of the person of being gathered, the height of piston rod 6 in the preceding test tube 4 of reasonable adjustment to can adapt to different urine volumes. When the actual sampling, can use the stool, place this device in the below of stool, do not change the mode that tradition went to the lavatory, can gather the urine. Urine will enter from urine receiving funnel 2, and first under the effect of baffle 7 and riser 9, urine will enter into preceding test tube 4. After the urine of current test tube 4 reached overflow pipe 15's height, the urine can enter into the reaction box 13 of being connected with preceding test tube 4, effervescent powder 14 in the reaction box 13 after meetting the urine, can produce a large amount of bubbles fast, the gas of production enters into the gasbag 11 that corresponds with left side pin 10 along trachea 12 in, make gasbag 11 rise greatly, after gasbag 11 rises greatly, can make left pin 10 reset upwards, riser 9 is not blockked by left pin 10 this moment. The shutter 7 will move to the right under the action of the compression spring 21 on the guide 20 and the riser 9 will be blocked by the pin 10 on the right. At this time, the through hole 8 of the baffle 7 corresponds to the pilot tube 5, and urine enters the interior of the pilot tube 5.

Similarly, after the urine in the middle test tube 5 is collected to a certain degree, the urine in the middle test tube 5 flows into the reaction box 13 corresponding to the middle test tube 5 through the overflow pipe 15, so that the generated gas pushes the pin 10 on the right side to reset upwards, the baffle 7 continues to move rightwards, and the through hole 8 in the baffle 7 corresponds to the rightmost joint 3. The last urine is completely drained by the connector 3.

Since the end of the overflow pipe 15 connected to the reaction chamber 13 is provided to the rubber packing 17, the gas cannot flow backward from the overflow pipe 15 into the front test tube 4 or the middle test tube 5. The degree of expansion of the air bag 11 is limited, so when the air pressure in the reaction chamber 13 is sufficiently high, the rubber stopper 19 at the bottom of the reaction chamber 13 is knocked off, and the residual liquid in the reaction chamber 13 flows away through the rightmost joint 3. The rightmost joint 3 can be directly led into a drain pipe or received by a container according to actual conditions. The whole collection process is pollution-free; in addition, because the effervescent powder 14 contains the aromatic, the reaction can generate fragrance, a certain deodorization effect is achieved, and the sanitary smell is prevented from being overlarge.

Because the front end urine has washed the urethra clean and has also washed main pipeline 1 of the whole device, after the collection, only need pull out test tube 5, the urine in test tube 5 is qualified sample.

The device can be made of disposable materials, namely, the device is directly discarded after detection is finished each time; ensuring no pollution of sampling.
