Description

Technical Field

[0001] The invention relates to the technical field of urinary catheterization devices, in particular to a double-balloon anti-detachment urinary catheter. Background Art

[0002] At present, the catheters used in clinical practice are generally catheters with balloons. After the catheter is inserted into the urethra, a syringe is used to inject saline into the balloon, so that the balloon is filled and floats in the bladder to achieve the effect of fixing the catheter. Figure 1 As shown, the water injection channel 3 in the balloon catheter is located on one side of the catheter 1, and there is only one opening in the balloon 4. When water is injected into the balloon 4 to fix it, the balloon on the opening side is always filled first and then extended to the surrounding and opposite side, resulting in uneven water injection pressure of the balloon 4 in the bladder. The balloon on the opening side has a large volume after being filled, while the balloon on the opposite side of the opening has a small volume after being filled, which affects the fixation effect of the catheter 1 and easily causes urine leakage. Summary of the invention

[0003] Aiming at the problem that the air bag of the existing air bag catheter expands unevenly after being filled with water, resulting in poor catheter fixation effect and easy urine leakage, the present invention provides a double-air bag anti-dropout catheter.

[0004] The present invention is implemented by adopting the following technical scheme: a double-airbag anti-slip urinary catheter, wherein an inner airbag and an outer airbag are arranged at the end of the urinary catheter, two inner airbag water injection channels and two outer airbag water injection channels are symmetrically arranged in the urinary catheter, the two inner airbag water injection channels are respectively connected to the inner airbag through the inner airbag water injection port, and the two outer airbag water injection channels are respectively connected to the outer airbag through the outer airbag water injection port.

[0005] When water is injected into the inner and outer airbags respectively through a syringe, water can be evenly injected into the two water injection channels of the airbag and enter the airbag through the water injection port, so that both sides of the airbag swell at the same time with equal pressure, the airbag expands evenly, and the catheter fixation effect is good.

[0006] The above-mentioned double-balloon anti-slip catheter has a two-way valve arranged in the injection tube at the other end of the catheter, the two-way valve comprises a shell, a rotating disk is rotatably arranged in the shell, a Y-shaped pipeline is arranged in the rotating disk, the Y-shaped pipeline is divided into a main pipeline and a branch pipeline, an inner airbag injection outlet and an outer airbag injection outlet are arranged at one end of the shell, an injection inlet is arranged at the other end of the shell, the injection inlet is connected with the injection channel in the injection tube, the inner airbag injection outlet is connected with two inner airbag water injection channels in the catheter, the outer airbag injection outlet is connected with two outer airbag water injection channels in the catheter, a Y-shaped switch is also arranged outside the shell, the Y-shaped switch is connected with the rotating disk inside the shell, and the rotation position of the Y-shaped switch is symmetrical with the rotation position of the Y-shaped pipeline inside the rotating disk.

[0007] The Y-type switch drives the rotating disk to rotate to realize the opening and closing of the two-way valve. When the two-way valve is opened, water can be injected into the inner airbag or the outer airbag. After the two-way valve is closed, the channels of the inner airbag and the outer airbag are in a closed state and are not connected to each other.

[0008] The double-balloon anti-dropout catheter of the present invention realizes double insurance for fixing the catheter by arranging inner and outer double balloons, and the inner and outer balloons have symmetrical water injection channels, the balloons expand evenly, and the fixing effect is good. A two-way valve is arranged in the injection tube of the catheter, and the channel of each balloon is independent and not interconnected, so that the inner and outer balloons are prevented from leaking each other.

DETAILED DESCRIPTION

[0018] A double-balloon anti-slip urinary catheter, an inner balloon 6 and an outer balloon 7 are arranged at the end of the urinary catheter 1, two inner balloon water injection channels 8 and two outer balloon water injection channels 9 are symmetrically arranged in the urinary catheter 1, the two inner balloon water injection channels are respectively connected to the inner balloon 6 through the inner balloon water injection port 10, when water is injected, water can be evenly injected into the two inner balloon water injection channels 8, so that both sides of the inner balloon 6 are expanded at the same time and the pressure is equal, and the inner balloon 6 expands evenly; the two outer balloon water injection channels 9 are respectively connected to the outer balloon 7 through the outer balloon water injection port 11, when water is injected, water can be evenly injected into the two outer balloon water injection channels 9, so that both sides of the outer balloon 7 are expanded at the same time and the pressure is equal, and the outer balloon 7 expands evenly.

[0019] A two-way valve 12 is arranged in the injection tube 5 at the other end of the urinary catheter 1. The two-way valve includes a shell 13. A rotating disk 14 is rotatably arranged in the shell 13. A Y-shaped pipe 15 is arranged in the rotating disk. The Y-shaped pipe is divided into a main pipe and a bifurcated pipe. An inner air bag injection outlet 16 and an outer air bag injection outlet 17 are arranged at one end of the shell. An injection inlet 18 is arranged at the other end of the shell. The injection inlet 18 is connected with the injection channel in the injection tube. The inner air bag injection outlet 16 is connected with two inner air bag water injection channels 8 in the urinary catheter. The outer air bag injection outlet 17 is connected with two outer air bag water injection channels 9 in the urinary catheter. A Y-shaped switch 19 is also arranged outside the shell 13. The Y-shaped switch 19 is connected to the rotating disk 14 inside the shell. The rotation position of the Y-shaped switch 19 is symmetrical with the rotation position of the Y-shaped pipe 15 inside the rotating disk, that is, the rotation position of the Y-shaped switch 19 also reflects the rotation position of the Y-shaped pipe 15 inside the rotating disk. The Y-shaped switch 19 can drive the rotating disk to rotate in the shell. After the two-way valve 12 is installed in the injection tube 5, the Y-type switch 19 is outside the injection tube 5, which is convenient for rotation operation.

[0020] Turn the Y-type switch 19 to connect the main pipeline of the Y-type pipeline with the injection inlet 18 and the inner airbag injection outlet 16. At this time, water can be injected into the inner airbag 6 through the syringe; if the Y-type switch 19 is turned, the branch pipeline of the Y-type pipeline is connected with the injection inlet 18 and the outer airbag injection outlet 17. At this time, water can be injected into the outer airbag 7 through the syringe; if the Y-type switch 19 is turned to turn the Y-type pipeline to other positions, the injection channels of the inner airbag 6 and the outer airbag 7 are closed, and the channels between the inner airbag 6 and the outer airbag 7 are also not connected to each other. The channels of the inner airbag 6 and the outer airbag 7 are both in a closed state to prevent leakage from the inner and outer airbags.

[0021] When pulling out the urinary catheter, first turn the Y-type switch 19 to connect the branch pipe of the Y-type pipe with the injection inlet 18 and the outer airbag injection outlet 17, and use a syringe to draw out the outer airbag liquid, then turn the Y-type switch 19 to connect the main pipe of the Y-type pipe with the injection inlet 18 and the inner airbag injection outlet 16, and use a syringe to draw out the inner airbag liquid, and finally pull out the urinary catheter.

[0022] The inner airbag 6 and the outer airbag 7 of the urinary catheter of the present invention both have two symmetrical water injection channels. The inner airbag 6 and the outer airbag 7 can be evenly expanded after water injection, and the urinary catheter has a good fixing effect. The water between the two layers of airbags not only avoids the mutual adhesion between the airbags, but also plays a buffering role. In addition, if the outer airbag 7 is accidentally ruptured, the inner airbag 6 can also play a role in fixing the urinary catheter 1. Finally, by setting a two-way valve 12, it can be ensured that the channel of the inner airbag 6 and the channel of the outer airbag 7 are both in a closed state, and the channels between the inner airbag 6 and the outer airbag 7 are not connected to each other, so as to prevent the inner and outer airbags from leaking, and solve the problem of preventing the water in the inner airbag 6 from flowing back to the outer airbag 7 after the outer airbag 7 is ruptured, thereby causing the tube to fall off.
