[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0024] See also Figure 1-4 The utility model is a catheter for enema of intussusception in children with anti-reflux, comprising a catheter body 1, a water storage ring 2 is opened and closed on the upper part of the catheter body 1, a water bag 3 fixedly connected to the catheter body 1 is sleeved on the catheter body 1, a water injection channel 4 is opened on the catheter body 1, the left side of the water injection channel 4 is connected to the water storage ring 2, the right end of the water injection channel 4 is connected to a water adding pipe 5, a hard valve 6 is installed on the water adding pipe 5, the left end of the catheter body 1 is opened with an annularly distributed water outlet 7, the right end of the catheter body 1 is fixedly connected to the It is connected to a fixing rod 8, and a water inlet 9 connected to the catheter body 1 is provided on the left side of the fixing rod 8. The top of the fixing rod 8 is fixedly connected to a liquid injection pipe 10 connected thereto. The inner wall of the fixing rod 8 is slidably connected to a sealing plug 11, and the left side of the sealing plug 11 contacts the inner wall of the water inlet 9. The right side of the sealing plug 11 is fixedly connected to a spring 12 and a limiting rod 13. The right end of the limiting rod 13 passes through and extends to the right side of the fixing rod 8, and the right end of the spring 12 is fixedly connected to the inner wall of the fixing rod 8.

[0025] In the present invention, when using the catheter, first, the left end of the catheter body 1 is placed into the patient's body, the water bag 3 is covered and completely entered into the rectum, then the user inserts the syringe filled with physiological saline into the water adding pipe 5, and then presses the syringe, the physiological saline will enter the water injection channel 4 from the water adding pipe 5, and then the physiological saline will enter between the water storage ring 2 and the water bag 3. As the physiological saline is continuously injected, the water bag 3 will expand, and the water bag 3 will be stuck in the anus after expansion, thereby locking the catheter body 1, effectively preventing the catheter body 1 from being discharged from the inside of the anus, and then the user can connect the injection tube 10 to the enema machine, and the enema machine will inject the enema liquid from the anus. Into the interior of the fixed rod 8. As the enema liquid enters the interior of the fixed rod 8, the enema liquid will push the sealing plug 11 to move to the right to compress the spring 12. The sealing plug 11 will then lose its seal on the water inlet 9. The enema liquid will then enter the interior of the catheter body 1 and be discharged into the patient's body from the water outlet 7, thereby achieving the effect of liquid injection. During the water change process of the enema machine, the sealing plug 11 inside the fixed rod 8 will lose the driving force of the enema liquid, the elastic force of the spring 12 will be released, and the spring 12 will drive the sealing plug 11 to slide to the left, sealing the water inlet 9, thereby achieving the effect of sealing the catheter body 1, effectively preventing the enema liquid from flowing back into the interior of the enema machine, thereby improving the practicality of the device.

[0026] See also Figure 3 and 4 , wherein: the inner wall of the catheter body 1 is embedded with a support sleeve 14 fixedly connected thereto, and the support sleeve 14 is located on the inner side of the water storage ring 2.

[0027] In the present invention, the setting of the support sleeve 14 can provide a certain supporting effect on the left end of the catheter body 1, which helps to insert the catheter body 1 into the patient's anus, and the setting of the support sleeve 14 can reinforce and support the water bag 3 and the inner side of the water storage ring 2, avoiding the situation where the water bag 3 expands and squeezes the catheter body 1 to reduce its inner diameter and affect the flow rate of the enema liquid, thereby improving the practicality of the device.

[0028] See also Figure 1-4 , wherein: the left end of the support sleeve 14 is fixedly connected to a ring-shaped fixed block 15, one side of the fixed block 15 passes through and extends to the outside of the catheter body 1, and the catheter body 1 is sleeved with a threaded ring 16, the inner side of the threaded ring 16 is fixedly connected to the fixed block 15, and the threaded ring 16 is sleeved with a limit sleeve 17 threadedly connected to it.

[0029] In the present invention, the fixing block 15 can support the threaded ring 16, and the setting of the threaded ring 16 can support the limiting sleeve 17. The user can drive the limiting sleeve 17 to be inserted into the water bag 3 by rotating it. The water bag 3 covered by the limiting sleeve 17 will not be able to expand. By adjusting the position of the limiting sleeve 17, the size of the water bag 3 that can be expanded can be adjusted, thereby realizing the use of children of different age groups. The size of the expanded water bag 3 is adjusted according to the size of the child's anus, which is conducive to reducing the discomfort caused to the child and can reduce the occurrence of the catheter body 1 being discharged, thereby improving the practicality of the device.

[0030] See also Figure 1-3 , wherein: the right end of the limiting rod 13 is fixedly connected to a disc 18, and the outer side of the disc 18 is provided with anti-slip grooves.

[0031] In the present invention, the arrangement of the disc 18 can limit the position of the limiting rod 13 and help the user to manually control the position of the sealing plug 11 through the limiting rod 13, thereby improving the practicality of the device.

[0032] See also Figure 1-3 , wherein: the catheter body 1 is provided with a waterproof paper 19 fixedly connected thereto, and the left side of the waterproof paper 19 is fixedly connected with an adhesive layer 20.

[0033] In the present invention, the adhesive layer 20 can stick the waterproof paper 19 on the patient's buttocks, thereby achieving the effect of fixing the catheter body 1 and improving the practicality of the device.

[0034] The above are only preferred embodiments of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
