In order to avoid the influence of impurities, the proximity switch 6 is triggered accurately, the outer edge surface of the floating ball 5 is a metal layer, and the proximity switch 6 is an inductive proximity switch 6. The inductive proximity switch 6 is to generate eddy current inside an object by using a conductive object when the object approaches the proximity switch 6, which can generate an electromagnetic field. The eddy current is reacted to the proximity switch 6, so that the internal circuit parameters of the switch are changed, whether a conductive object is close or not is identified, and the on-off of the switch is controlled; the object that such a proximity switch 6 can detect must be an electrical conductor.

The whole body of the invention can be divided into two parts, namely a box body 1 and a clamping device 2 arranged in the box body 1, which belong to a fixed part and can be recycled; the receiving hopper 4, the bag 3 and the disposable rubber band 8 belong to disposable articles, and only the part needs to be replaced for each sampling; the floating ball 5 can be used for one time according to the requirements of the conditions, and can also be used for multiple times after being cleaned and disinfected. Wherein the bag 3 is a slender plastic bag, and the length is consistent with the height of the box body 1.

Before the device is used, the receiving hopper 4 is clamped on the buckle 7 on the left side of the box body 1, then the floating ball 5 is placed in the bag 3, and the upper end of the bag 3 is tied at the lower end of the receiving hopper 4 through the disposable rubber band 8. Then, pulling the corresponding stop block 210 on each layer of the front side surface of the box body 1 to enable the stop blocks 210 to be positioned on the right side of the stroke of the stop blocks; that is, the stopper 210 is stopped by the elastic pin 211; at this time, the left end of the shift lever 207 does not press the push switch 209, that is, the first electromagnet 204 and the second electromagnet 205 are both in the power-off state; the chucking device 2 is in a state as shown in fig. 2, in which the front support arm 202 and the rear support arm 203 are away from each other.

When sampling is needed, the power is switched on, the vertical state of the bag 3 is kept, and the bag 3 passes through the position between the front support arm 202 and the rear support arm 203 of each layer; then, urine is put in from the receiving hopper 4; at this point, urine will flow from the receiving hopper 4 into the bag 3 and fall directly to the bottom of the bag 3. The floating ball 5 will gradually rise along with the increase of urine. The outer edge surface of the floating ball 5 is a metal layer, and the left side surface of the box body 1 is provided with a plurality of proximity switches 6 from top to bottom; when the floating ball 5 blocks the proximity switch 6, the proximity switch 6 is closed at the moment, so that the third electromagnet 212 is electrified; then, the third electromagnet 212 attracts the elastic pin 211 to move backwards, and the elastic pin 211 is not in the blocking stop 210, at this time, the shift lever 207 is reset to the left under the action of the pressure spring 208 sleeved on the shift lever 207, and the left end of the shift lever 207 presses the push switch 209, so that the first electromagnet 204 and the second electromagnet 205 are simultaneously electrified, and the side, close to each other, of the first electromagnet 204 and the second electromagnet 205 is opposite in polarity; the first electromagnet 204 and the second electromagnet 205 will attract each other; and pulls the front support arm 202 and the rear support arm 203 to close each other, and finally the fixing blocks on the front support arm 202 and the rear support arm 203 are attached together, so that the bag 3 is tightly clamped, and the urine in the bag 3 is isolated.

Because floater 5 upwards floats from bottom to top gradually, consequently chucking device 2 from bottom to top can seal bag 3 in proper order, makes the urine in bag 3 from bottom to top be cut apart into the multistage. So that the whole urine is divided into a plurality of sections and stored in the bag 3.

The process does not need human intervention, and only needs normal urination; simple and fast, and is suitable for the old and children.

After the urine is cut apart into the multistage and exists in bag 3, needs medical personnel or relatives etc. people this moment, draws middle section urine, and the concrete way is: according to the height of urine and the volume of midstream urine to be collected, the urine in the middle area of the bag 3 is reasonably selected for extraction; for example, the fourth, fifth and sixth layers from bottom to top are taken as sampling layers; at this time, the shift lever 207 on the fifth layer and the sixth layer is shifted in sequence, so that the shift lever 207 is blocked by the elastic pin 211 again to the right. (since the float ball 5 has risen to the highest position, the proximity switch 6 of the layer is in the off state, namely the elastic pin 211 can reset). After the shifting lever 207 is shifted to the right, the shifting lever 207 does not extrude the press switch 209 any more, the first electromagnet 204 and the second electromagnet 205 are powered off, the front support arm 202 and the rear support arm 203 are respectively positioned under the action of the tension spring 214, and therefore the front support arm and the rear support arm 203 of the fifth layer and the sixth layer are not clamping the bag 3 at the moment; finally, the urine in the fourth fifth layer and the sixth layer is mixed together; then the urine is drawn by a syringe or pricked by a cone, and collected in a test tube for inspection.

After the middle section urine sampling is finished, the bag 3 is tied to be opened, and the unified disposal is carried out.

In the in-service use process, wrap up or hidden installation to box 1, prevent that the urine from spattering on box 1 to carry out regularly clearance disinfection, keep holistic health.

According to the device, the box body 1 is arranged, the upper clamping device 2 and the lower clamping device 2 are arranged in the box body 1, so that the urine in the bag 3 can be layered by the clamping devices 2, and the urine can be layered continuously along with the continuous inflow of the urine; the whole process is automatically finished, manual operation is not needed, and simplicity and rapidness are realized; the learning cost is low; meanwhile, the box body 1 and accessories belong to the part of recycling, and are not required to be discarded every time, so that the cost is saved.

According to the device, the flexible disposable plastic bag 3 is arranged, the urine in the bag 3 is automatically divided into a plurality of layers by utilizing the flexibility characteristic of the bag 3 and clamping the plurality of layers, so that the mixing of the urine at the front end, the urine at the middle end and the urine at the rear end is avoided, and the sampling accuracy is improved; simultaneously, after the middle section urine is combined, the bag 3 is punctured, the needed middle section urine can be taken out quickly and conveniently, and the operation convenience is improved.

The device is low in cost for single use, and sampling can be completed by replacing the receiving hopper 4, the bag 3 and the rubber band 8; simultaneously supplementary sample test tube, widgets such as pjncture needle, alright in order to accomplish a sample.

This device is owing to can be automatic carry out quantitative layering with no matter how much urine, consequently can be applicable to adult or child of different urine volume sizes, later can be as required to the middle section of taking whole urine and send for inspection, has improved the accuracy.
