Detailed Implementation

[0024] To achieve the above objectives and effects, the technical means and structure adopted by the present invention will be described in detail with reference to the accompanying drawings, focusing on the features and functions of the preferred embodiments of the present invention.

[0025] like Figure 1-3 As shown, this invention provides a urological catheter, comprising:

[0026] The catheter body 1 has a catheterization chamber 2, a dripping chamber 3 and an irrigation chamber 4 inside the catheter body 1;

[0027] The catheterization chamber 2 is used to drain urine from the bladder; the instillation chamber 3 is used to instill medication into the bladder or urethra; and the irrigation chamber 4 is used to irrigate the bladder.

[0028] The end of the catheter body 1 is provided with a catheter port communicating with the catheterization cavity 2 and a flushing port communicating with the flushing cavity 4;

[0029] The connecting tube 5 is connected to the catheter body 1 at its first end. The second end of the connecting tube 5 is equipped with an independent catheter head 6, a drip head 7, and a flushing head 8. The catheter head 6 is connected to the catheter cavity 2, the drip head 7 is connected to the drip cavity 3, and the flushing head 8 is connected to the flushing cavity 4.

[0030] In this embodiment, the side wall of the catheter body 1 is provided with a plurality of drip ports 9 that communicate with the drip chamber 3, and the plurality of drip ports 9 are arranged along the axial direction of the catheter body 1.

[0031] In another embodiment, multiple drip chambers 3 are provided, each corresponding to and individually connected to multiple drip outlets 9; multiple drip heads 7 are provided, each connected to a multiple drip chamber 3. Thus, by injecting medication into different drip heads 7, the medication can exit the drip chamber 3 from different drip outlets 9 at different positions on the catheter body 1, achieving precise control over the medication leakage site.

[0032] Specifically, multiple drip chambers 3 are arranged circumferentially along the main body 1 of the catheter, and the flushing chamber 4 and the catheterization chamber 2 are located between the multiple drip chambers 3.

[0033] Preferably, the different dropper heads 7 are different colors to facilitate differentiation.

[0034] In another embodiment, the catheter body 1 also includes an airway 15, the first end of the airway 15 is connected to the end of the dripping chamber 3 away from the connecting pipe 5, and the second end of the airway 15 is connected to a first air source; a drug inlet 14 is provided on the side wall of the catheter body 1, the drug inlet 14 is connected to the dripping chamber 3, the drug inlet 14 is close to the dripping head 7, and the dripping head 7 is connected to a second air source;

[0035] The dripping chamber 3 is provided with a first stop 10 and a second stop 11, which are slidably and sealingly connected to the dripping chamber 3.

[0036] The drip nozzle 9 is a pressure-type opening that opens outwards when subjected to a certain pressure.

[0037] In use, medical staff can draw or blow air into the drip chamber 3 through the first and second air sources to adjust the positions of the first and second blocks 10 and 11 by adjusting the air pressure, so that they are located on both sides of the drug inlet 14. Then, the medicine is added into the drip chamber 3 through the drug inlet 14. At this time, the first and second air sources slowly draw air to reduce the air pressure outside the first and second blocks 10 and 11, so that the first and second blocks 10 and 11 can be easily moved outward. As the medicine is added, the first and second blocks 10 and 11 move away from each other under the action of the medicine, and the medicine enters the area between the first and second blocks 10 and 11. Then, the first air source draws air outward, and the second air source blows air, causing the first baffle 10, the medicine liquid, and the second baffle 11 to move towards the dripping port 9. When they reach the corresponding dripping port 9 where the medicine liquid needs to seep out, the first baffle 10 and the second baffle 11 are positioned on both sides of the target dripping port 9. The first air source and the second air source blow air simultaneously, and the first baffle 10 and the second baffle 11 begin to move relative to each other, so that the medicine liquid applies pressure to the dripping port 9. When the pressure reaches a certain level, the target dripping port 9 opens outward under the action of pressure, and the medicine liquid gradually leaves the target dripping port 9, achieving precise control of the seepage site. After the medicine liquid is added, the dripping port 9 is no longer under pressure and automatically closes.

[0038] Specifically, position sensors are provided on the first stop 10 and the second stop 11 to precisely control their positions and confirm their movement status.

[0039] Specifically, as the liquid medicine moves toward the target dripping port 9, since the first stop 10 and the second stop 11 do not apply much pressure, the dripping port that the liquid medicine moves through will not open, thus preventing the liquid medicine from leaving the dripping chamber 3 prematurely.

[0040] In this embodiment, the first baffle 10 has a first inclined surface at one end near the second baffle 11, and the second baffle 11 has a second inclined surface. The first and second inclined surfaces form a V-shaped opening, with the open end of the V-shaped opening close to the dosing port 14. This V-shaped opening facilitates the addition of liquid medicine from the dosing port 14. The pressure during the addition of liquid medicine causes the first baffle 10 and the second baffle 11 to move away from each other, reducing the operational requirements on the first and second air sources.

[0041] In another embodiment, a traction wire 12 is provided inside the flushing chamber 4. The traction wire can increase the rigidity of the catheter body 1, making it easier to insert the catheter body.

[0042] In another embodiment, a plurality of annular frames 13 are axially arranged on the inner wall of the end of the flushing chamber 4 away from the connecting pipe 5. Multiple traction wires 12 are arranged circumferentially and connected to the annular frames 13. This allows bending of the annular frames 13 to be achieved by manipulating different traction wires 12, facilitating operation.

[0043] In another embodiment, the catheter body 1 is provided with a pressure sensor, a pH sensor and a temperature sensor.

[0044] Pressure sensors are used to monitor pressure changes in the urethral sphincter and bladder neck, and the position of the catheter body 1 is determined based on these pressure changes.

[0045] Specifically, when the pressure value is in the range of 800-1500Pa and shows a steep rise-plateau-slow fall waveform, the end of the catheter body 1 crosses the bladder neck, and when a rhythmic pressure fluctuation of 5-8Hz is detected, it is located in the external urethral sphincter area.

[0046] Specifically, a balloon is provided on the outer wall of the catheter body 1. The balloon is used to fix the catheter body 1, and the pressure sensor can be set on the inner wall of the balloon.

[0047] pH sensors can continuously monitor changes in urine pH, allowing healthcare professionals to add different medications based on these changes.

[0048] Specifically, the pH sensor can be installed at the drip inlet.

[0049] Temperature sensors can continuously monitor temperature changes in the bladder and urethra to determine if inflammation has occurred. If inflammation is found, medical staff can choose to flush with saline solution or add anti-inflammatory drugs based on the temperature.

[0050] The above description is only a preferred embodiment of the present invention and not all embodiments. Anyone should know that structural changes made under the guidance of the present invention, and any technical solutions that are the same as or similar to the present invention, are within the protection scope of the present invention.
