DETAILED DESCRIPTION

[0026] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1

[0028] A preferred embodiment of the prostate perfusion tube provided by the utility model is as follows Figures 1 to 5 As shown: a prostate perfusion tube, including a tube body 1, a connecting tube 2 is fixedly connected to the right side of the tube body 1, a bladder air bag air injection cavity 4 is arranged on the right side of the connecting tube 2, a drug injection cavity 5 is arranged below the bladder air bag air injection cavity 4, a urethral air bag air injection cavity 6 is arranged above the drug injection cavity 5, a urethral air bag body 7 is fixedly connected to the surface of the tube body 1, a bladder air bag body 8 connected to the tube body 1 is arranged on the left side of the urethral air bag body 7, a through hole 9 is opened inside the tube body 1, and a drug outlet 18 is opened on the surface of the tube body 1 and located between the urethral air bag body 7 and the bladder air bag body 8.

[0029] In this embodiment, the bladder balloon body 8 and the urethral balloon body 7 are spherical in design, and the surfaces of the bladder balloon body 8 and the urethral balloon body 7 are smooth and flat, which can avoid scratching the patient when they are introduced into the patient's body.

[0030] In this embodiment, the drug outlets 18 are arranged in a circular shape with equal distances from the center of the tube body 1, so that the drug can be sprayed from all sides, making the drug spray more uniform.

[0031] In this embodiment, the through hole 9 is provided at the gap between the two groups of drug outlets 18. By providing the through hole 9, it is convenient to insert the auxiliary tube into the through hole 9 when the injection tube is used.

[0032] In this embodiment, the bladder airbag air injection cavity 4, the drug injection cavity 5, and the urethral airbag air injection cavity 6 are all designed to be interconnected with the tube body 1. The three are interconnected with the tube body 1, which can facilitate medical staff to perform air injection and drug injection operations.

[0033] Example 2

[0034] Based on Example 1, a preferred embodiment of a prostate perfusion tube provided by the utility model is as follows Figures 1 to 5 As shown: a connecting ring 16 is fixedly connected to the surface of the tube body 1, a connecting plate 11 is fixedly connected inside the connecting ring 16, a mounting plate 10 is fixedly connected to the inner wall of the connecting plate 11, a limiting rod 12 is slidably connected inside the mounting plate 10, a rubber ball 13 is fixedly connected to the tail of the limiting rod 12, a spring 14 fixedly connected to the connecting plate 11 is fixedly connected to the side of the rubber ball 13, a sealing ring 15 fixedly connected to the inner wall of the connecting ring 16 is provided on the other side of the rubber ball 13, a spare tube 17 is fixedly connected to the top of the tube body 1, and a connecting hole 3 is opened inside the sealing ring 15.

[0035] In this embodiment, the spare tube 17 is arranged at an angle on the top of the tube body 1 . The inclined arrangement makes it easy to insert the spare catheter from the spare tube 17 into the tube body 1 .

[0036] In this embodiment, the limiting rod 12 and the connecting plate 11 are arranged perpendicular to each other, and the limiting rod 12 is connected to the center of the rubber ball 13. The countercurrent liquid will push the limiting rod 12 under the action of the flow velocity, and the limiting rod 12 will push the rubber ball 13 so that the rubber ball 13 contacts the inner wall of the sealing ring 15.

[0037] In this embodiment, the sealing ring 15 is designed in a conical shape and is located on the movement trajectory of the rubber ball 13. Since the sealing ring 15 is designed in a conical shape, when the rubber ball 13 contacts the sealing ring 15, the left side of the sealing ring 15 is closed.

[0038] In this embodiment, the rubber ball 13 is hollow inside, and the inner diameter of the left side of the sealing ring 15 matches the rubber ball 13. The rubber ball 13 makes the left side of the sealing ring 15 form a closed structure. Since the rubber ball 13 is hollow, it is easier to move under the drive of the flowing liquid.

[0039] The working principle and use process of the utility model are as follows: first, the tube body 1 is inserted into the patient's body, and air is inflated into the urethral air bag body 7 and the bladder air bag body 8 through the urethral air bag injection cavity 6 and the bladder air bag injection cavity 4, so that the two can open the urethra and the bladder, and then the tube injection cavity 5 is used to inject drugs into the tube body 1, and the drugs will finally flow out to the surroundings through the drug outlet 18, so as to achieve the purpose of treating the prostate.

[0040] By providing the sealing ring 15, when liquid backflow occurs inside the tube body 1, the backflowing liquid will push the limiting rod 12 under the action of the flow velocity, and the limiting rod 12 will then push the rubber ball 13, so that the rubber ball 13 contacts the inner wall of the sealing ring 15. Since the sealing ring 15 is conical in design, when the rubber ball 13 contacts the sealing ring 15, the left side of the sealing ring 15 will be closed to prevent the liquid from continuing to flow back. When the liquid stops flowing back, the spring 14 will drive the rubber ball 13 back to the initial position to open the sealing ring 15.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
