[0023] The following will combine the drawings to specifically describe the technical scheme provided by each embodiment of the utility model.
[0024] The utility model discloses an anti -backflow integrated urine bag, including urinary bag 1 and catheter 2, the top of urinary bag 1 is equipped with the port 11, the catheter 2 is located urinary bag 1 top, the bottom of catheter 2 is connected with the liquid storage pipe 21 for temporary storage urine, the bottom of liquid storage pipe 21 is equipped with the anti -backflow component 3 for preventing urine backflow, the anti -backflow component 3 is connected with the port 11 place of urinary bag 1, the anti -backflow component 3 includes anti -backflow pipe 31 and anti -backflow board 32, anti -backflow pipe 31 is located between liquid storage pipe 21 and the port 11 of urinary bag 1, and the anti -backflow pipe 31 with liquid storage pipe 21 and urinary bag 1 between all are the communicating state, the communicating place between anti -backflow pipe 31 and liquid storage pipe 21 is the top opening part of anti -backflow pipe 31, anti -backflow board 32 is located in the inner tube wall of anti -backflow pipe 31, the outer diameter of anti -backflow board 32 with the inner diameter of anti -backflow pipe 31 inner tube wall is adapted, so that anti -backflow board 32 can be vertically up and down in the inner tube wall of anti -backflow pipe 31, a plurality of liquid leakage holes 33 for discharging urine are arranged on anti -backflow board 32, and when anti -backflow board 32 is abutted at the communicating place of anti -backflow pipe 31 and catheter 2, a plurality of liquid leakage holes 33 are covered by the part of the inner top of anti -backflow pipe 31 without opening, the anti -backflow component 3 still includes the float ball 34 with certain buoyancy, the float ball 34 is located in the interior of anti -backflow pipe 31 and is between anti -backflow board 32 and the port 11 of urinary bag 1;
[0025] When using, first, one end of catheter 2 is connected to the patient's body, and the urine in the patient's body is discharged into catheter 2 through the pressure of the human body, and the urine slowly flows into liquid storage pipe 21 along catheter 2, because anti -backflow pipe 31 and liquid storage pipe 21 and urinary bag 1 are in communication, and a plurality of liquid leakage holes 33 for discharging urine are arranged on anti -backflow board 32, so the urine can flow to the port 11 of urinary bag 1 through anti -backflow pipe 31 and a plurality of liquid leakage holes 33 on anti -backflow board 32, and finally flow into urinary bag 1 for storage;
[0026] At this point, if the patient is in a lying position, the urine bag 1 is squeezed due to turning over or other reasons, and the urine stored in the urine bag 1 backflows, the backflowing urine flows into the anti-backflow tube 31 from the port 11 of the urine bag 1, at this time, the floating ball 34 in the anti-backflow tube 31 is driven to move in the direction of the urine backflow by the buoyancy of the backflowing urine, wherein the floating ball 34 can be a hollow plastic ball or other material with a certain buoyancy, the floating ball 34 moves while resisting the anti-backflow plate 32, thereby pushing the anti-backflow plate 32 to move vertically upward in the direction of the communication between the anti-backflow tube 31 and the urinary catheter 2, until the anti-backflow plate 32 blocks the communication between the anti-backflow tube 31 and the urinary catheter 2, so that the floating ball 34 cannot continue to move upward, at this time, the plurality of liquid leakage holes 33 on the anti-backflow plate 32 are covered by the top part of the inner wall of the anti-backflow tube 31, thereby blocking the backflowing urine in the anti-backflow tube 31, which can effectively prevent the urine from continuing to backflow.
[0027] The backflowing urine can be blocked in the anti-backflow tube 31 by the anti-backflow assembly 3, thereby preventing the urine from continuing to backflow into the urinary catheter 2 and then into the patient's body, which can pollute the patient's internal environment, and can effectively prevent the impact on the patient's body caused by the backflowing urine with too large a flow rate, thereby reducing the discomfort of the patient's body.
[0028] In a further preferred embodiment of the utility model, the anti-backflow plate 32 is provided with a magnet 35, the outer diameter of the magnet 35 is matched with the inner diameter of the top opening of the anti-backflow tube 31, a metal sheet 36 is arranged in the top opening of the anti-backflow tube 31, and the anti-backflow plate 32 is just stopped at the top opening of the anti-backflow tube 31 under the mutual attraction between the magnet 35 and the metal sheet 36.
[0029] When the urine backflows, if the flow rate of the urine is too large, a small amount of urine may penetrate the plurality of liquid leakage holes 33 on the anti-backflow plate 32 and flow into the urinary catheter 2 through the communication between the anti-backflow tube 31 and the urinary catheter 2, the magnet 35 is arranged on the anti-backflow plate 32, the metal sheet 36 is arranged in the top opening of the anti-backflow tube 31, and the anti-backflow plate 32 is just stopped at the top opening of the anti-backflow tube 31 under the mutual attraction between the magnet 35 and the metal sheet 36, when the floating ball 34 drives the anti-backflow plate 32 to move in the direction of the communication between the anti-backflow tube 31 and the urinary catheter 2, the mutual attraction between the magnet 35 and the metal sheet 36 can improve the moving speed of the anti-backflow plate 32, so that the anti-backflow plate 32 can quickly block the communication between the anti-backflow tube 31 and the urinary catheter 2, thereby preventing a small amount of urine from flowing into the urinary catheter 2 through the communication between the anti-backflow tube 31 and the urinary catheter 2.
[0030] The outer side wall of the magnet 35 is sleeved with a sealing ring 4 matched with the top opening of the anti-backflow pipe 31, the sealing ring 4 can be made of rubber or synthetic resin and has sealing property, the outer side wall of the magnet 35 is sleeved with the sealing ring 4 matched with the top opening of the anti-backflow pipe 31, the gap between the anti-backflow plate 32 and the top opening of the anti-backflow pipe 31 is sealed, and a small amount of urine is prevented from backflowing from the gap between the anti-backflow plate 32 and the top opening of the anti-backflow pipe 31.
[0031] In the further preferred embodiment of the utility model, the port 11 of the urinary bag 1 is rectangularly arranged, and the inner diameter of the port 11 is smaller than the outer diameter of the float ball 34. Since the float ball 34 has a certain gravity, the float ball 34 will be stopped at the port 11 of the urinary bag 1 when the urine does not backflow. If the port 11 of the urinary bag 1 is circularly arranged, the port 11 of the urinary bag 1 will be completely blocked, which prevents the urine from entering the urinary bag 1 and affects the normal use of the device. By arranging the port 11 of the urinary bag 1 to be rectangular and the inner diameter of the port 11 to be smaller than the outer diameter of the float ball 34, the urine can flow out from the gap between the float ball 34 and the port 11 of the urinary bag 1, which prevents the float ball 34 from blocking the urine and affects the catheterization effect.
[0032] The above merely describes the embodiments of the utility model and is not used to limit the utility model. The utility model can be changed and varied in various ways for those skilled in the art. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the claim range of the utility model.
