At the same time, the on-off component will also drive the check piece to work during operation to prevent the probe 7 from falling off after being inserted into the patient's bladder. With the mutual cooperation of the prompt component, the on-off component and the check piece, the problem that the doctor can only judge the insertion length of the existing catheter by feeling after insertion, and cannot judge whether it has been inserted into the bladder well, and at the same time, it needs to be tied with tape from the outside after insertion to prevent the catheter from falling off, which is inconvenient in actual use.

As shown in Figures 1, 4 and 6, the prompt component includes a sealing slider 22, a first rectangular cavity 20 is opened inside the docking rod 5, one side of the first rectangular cavity 20 penetrates to the outside of the docking rod 5, and a transparent partition 21 is fixed between the inner walls of the first rectangular cavity 20 near the edge of the outer surface of the docking rod 5. The sealing slider 22 is slidably connected between the inner walls of the first rectangular cavity 20 and is located at the top edge. The outer surface of the sealing slider 22 is in contact with the outer surface of one side of the transparent partition 21, and a guide hole 25 is opened at the top of the probe 7 near one side edge and penetrates to the top of the first rectangular cavity 20.

When the probe 7 is inserted into the patient's bladder, after the probe 7 reaches the patient's bladder, the urine inside the bladder enters the inner top surface of the first rectangular cavity 20 under the guidance of the guide hole 25. Since the patient's bladder has a certain outward squeezing force on the internal urine, when the urine reaches the inside of the first rectangular cavity 20, it will push the sealing slider 22 downward. When the operator observes that the sealing slider 22 slides downward, it can be known that the probe 7 has been inserted into the patient's bladder.

As shown in Figures 1, 4 and 5, the on-off assembly includes a sealing adjustment block 27, a second rectangular cavity 26 is provided inside the probe 7, the sealing adjustment block 27 is slidably connected between the inner walls of the second rectangular cavity 26, and is located at the bottom edge, a bridging hole 23 is connected between the inner bottom surface of the second rectangular cavity 26 and the inner bottom surface of the first rectangular cavity 20, the interior of the first rectangular cavity 20 is located below the sealing slider 22 and is filled with pure water, and the pure water spreads to the inner bottom surface of the second rectangular cavity 26 through the bridging hole 23, a U-shaped flow channel 29 is provided inside the sealing adjustment block 27, and both ends of the U-shaped flow channel 29 are connected.

The inside of the second rectangular cavity 26 is located above the sealing adjustment block 27 and is filled with sealing oil. The sealing oil spreads through the side holes 30 to the middle of the cavity formed between the elastic rubber membrane 32 and the inside of the arc-shaped groove 31.

The effect achieved is that as the sealing adjustment block 27 slides upward along the second rectangular cavity 26, the sealing oil in the second rectangular cavity 26 is squeezed upward, and the squeezed sealing oil flows into the cavity formed between the elastic rubber membrane 32 and the inside of the arc groove 31 through the side hole 30, so that the elastic rubber membrane 32 expands on the outer surface of the probe 7. The expanded elastic rubber membrane 32 can be engaged between the patient's bladder and the entrance of the urethra to prevent the probe 7 from falling off.

As shown in Figures 1, 2, 3, 6 and 7, a storage groove 2 is opened near the top edge of one side of the storage bucket 1, two T-shaped card plates 8 are fixed to the inner wall of one side of the storage groove 2, and the sampling bottle 3 is placed inside the storage groove 2. Two T-shaped card slots 9 are fixed on one side of the sampling bottle 3. The two T-shaped card plates 8 are correspondingly engaged in the inside of the T-shaped card slots 9. A bending tube 10 is fixed to the inner wall of one side of the storage bucket 1, and one end of the bending tube 10 is connected to the inside of the storage groove 2. An elliptical The piston 11 has a water outlet 17 extending to the outside near the bottom edge of the inner wall of one side of the sampling bottle 3, and the water outlet 17 is opposite to the inlet of the bending tube 10. The inside of the elliptical piston 11 is hollow, and the inside of the elliptical piston 11 is rotatably connected with an adjusting disk 12. The top of the elliptical piston 11 has a water inlet 14 extending to the inside, and one side of the elliptical piston 11 has a through hole 40 extending to the inside. The inside of the elliptical piston 11 has a bending hole 13, and one end of the bending hole 13 extends to the adjusting disk 1 2, and is opposite to the water inlet 14, the other end of the bent hole 13 penetrates to one side of the adjusting disk 12, and is opposite to the through hole 40, a handle 15 is fixed to the bottom of the adjusting disk 12, and the bottom of the handle 15 slides and penetrates to the bottom of the sampling bottle 3, a first spring 16 is fixed between the bottom of the elliptical piston 11 and the inner bottom surface of the sampling bottle 3, a threaded column 33 is provided on the top of the sampling bottle 3, the threaded column 33 is threadedly connected to the inside of the docking port 38, and an adjusting cavity 34 is opened inside the threaded column 33, and the adjusting cavity A sealing block 35 is provided inside 34, the top of the adjusting chamber 34 passes through the top of the threaded column 33, the bottom of the adjusting chamber 34 passes through the bottom of the threaded column 33, the bottom of the convex tube 18 extends into the adjusting chamber 34, and fits with the top of the sealing block 35, a second spring 36 is fixed between the bottom of the sealing block 35 and the inner bottom surface of the adjusting chamber 34, limiting grooves 39 are provided on the inner walls on both sides of the adjusting chamber 34, and limiting blocks 37 that slide and engage in the limiting grooves 39 are fixed on both sides of the sealing block 35.

The effect achieved is that urine flows from the water outlet channel 24 into the interior of the convex tube 18, flows into the interior of the regulating chamber 34 through the side port 19 on the convex tube 18, and finally flows into the interior of the sampling bottle 3 from the bottom of the regulating chamber 34. As the amount of urine in the sampling bottle 3 increases, the downward pressure on the elliptical piston 11 will also increase accordingly. When the elliptical piston 11 is pressed down to a position where the through hole 40 and the water outlet 17 are opposite, the sampling bottle 3 is in a full collection state. At this time, when there is still urine in the patient's bladder that has not been emptied, after the probe 7 is pulled out, the patient's urge to urinate will not disappear, and urine leakage will occur immediately. Therefore, the handle 15 needs to be turned at this time. The bending hole 13 is connected to the water inlet 14 and the through hole 40, and the urine in the sampling bottle 3 is guided to the water outlet 17 and discharged to the bending tube 10. The bending tube 10 can prevent external air from entering the interior of the sampling bottle 3 from the bending tube 10 when discharging urine, resulting in a reduction in the urine in the sampling bottle 3. When the patient's urine is completely discharged, the urine in the sampling bottle 3 becomes less, and the downward pressure on the elliptical piston 11 is reduced. At this time, the elliptical piston 11 can be lifted upward under the elastic force of the first spring 16, so that the water outlet 17 and the through hole 40 are misaligned, which can prevent the urine in the sampling bottle 3 from being completely discharged.

Working principle for drawing urine out from the patient's bladder: in actual operation, the length of the silicone guide rod 6 is determined by the actual usage. When in use, the probe 7 needs to be inserted into the bladder along the patient's urethra. In the process of inserting the probe 7 into the patient's bladder, when the probe 7 reaches the patient's bladder, the urine inside the bladder enters the inner top surface of the first rectangular cavity 20 under the guidance of the guide hole 25. Since the patient's bladder has a certain outward squeezing force on the internal urine, when the urine reaches the inside of the first rectangular cavity 20, it will push the sealing slider 22 downward. When the operator observes that the sealing slider 22 slides downward, it knows that the probe 7 has been inserted into the patient's bladder. In the process of the sealing slider 22 sliding downward, the pure water inside the first rectangular cavity 20 will be pushed into the second rectangular cavity 26. The sealing adjustment block 27 is lifted upward along the second rectangular cavity 26. During the upward lifting process, when the openings at both ends of the U-shaped flow channel 29 are opposite to the water outlet channel 24 and the water inlet channel 28, the water outlet channel 24 and the water inlet channel 28 can be connected, so that the urine inside the patient's bladder enters the U-shaped flow channel 29 through the water inlet channel 28 and then enters the water outlet channel 24, and the urine can be discharged to the outside. At the same time, the sealing adjustment block 27 will squeeze the sealing oil in the second rectangular cavity 26 upward during the upward sliding of the second rectangular cavity 26. The squeezed sealing oil flows into the cavity formed between the elastic rubber membrane 32 and the inside of the arc groove 31 through the side hole 30, so that the elastic rubber membrane 32 expands on the outer surface of the probe 7. The expanded elastic rubber membrane 32 can be engaged between the patient's bladder and the entrance of the urethra to prevent the probe 7 from falling off.
