[0024] The following will be combined with the drawings in 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 in 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.

[0025] The utility model provides Figure 1-Figure 3 An enema tube for treating ulcerative colitis shown in the figure comprises an enema tube main body 1 , wherein the enema tube main body 1 comprises a tube body 11 and an expansion balloon 12 .

[0026] One end of the tube body 11 is provided with a liquid outlet 14, and the other end is connected with a liquid inlet tube 13. The liquid inlet tube 13 is funnel-shaped and is used for operators to inject enema liquid, which can flow along the tube body 11 and finally flow out from the liquid outlet 14 to inject the enema liquid into the patient's body.

[0027] The expansion bladder 12 is arranged in the middle of the tube body 11 and covers the tube body 11 in the circumferential direction; the expansion bladder 12 is connected to an inflation tube 121, the inflation tube 121 is close to the tube body 11 and extends along the tube body 11 to one side of the liquid inlet tube 13, the end of the inflation tube 121 is connected to an extension tube 124, and the end of the extension tube 124 is connected to an inflation ball 123. Among them, the part of the middle part of the tube body 11 located inside the expansion bladder 12 has a symmetrically arranged inner bladder 15 formed by being recessed inward. The expansion bladder 12 and the inner bladder 15 form a bladder cavity of an annular structure, and the bladder cavity can contain gas to expand the expansion bladder 12 outward and squeeze the inner bladder 15 inward. The inflation ball 123 is a hand-kneading inflation ball 123, and the operator can repeatedly squeeze the inflation ball 123 to inflate and pressurize the bladder cavity through the extension tube 124 and the inflation tube 121. The ends of the inflation tube 121 and the extension tube 124 are provided with mutually adapted and mutually plugged connection sleeves 122, thereby realizing the connection between the inflation tube 121 and the extension tube 124 and facilitating disassembly.

[0028] In order to facilitate the user to control the air pressure in the expansion bag 12, the extension tube 124 is connected to an air valve 125 located on one side of the inflatable ball 123. The air valve 125 is composed of a deflation pipe and a pipe plug that closes the deflation pipe. When the operator removes the pipe plug, the gas in the bag cavity can be discharged through the deflation pipe.

[0029] In the present invention, a second layer of anti-backflow structure is provided, and a valve 17 for preventing the backflow of the liquid medicine is provided in the tube body 11 and is located below the inner capsule 15. When the liquid medicine is injected into the tube body 11, the valve 17 can be squeezed open to flow toward the liquid outlet 14, and the valve 17 can intercept the enema liquid located on the side of the liquid outlet 14 to prevent backflow.

[0030] Furthermore, in order to prevent the liquid outlet 14 from being squeezed and deformed, a reinforcement ring 141 is fixed to the inner wall of the liquid outlet 14. The reinforcement ring 141 is made of hard plastic to ensure the structural stability of the liquid outlet 14 and the normal injection of the enema liquid.

[0031] It should be added that the outer surface of the inflatable ball 123 is provided with a plurality of anti-slip strips of annular structure. Figure 1 In this embodiment, four anti-slip strips are provided, and are symmetrically arranged in pairs. The anti-slip strips can increase the friction when the operator holds the inflatable ball 123.

[0032] In addition, the portion of the tube body 11 located above the expansion bladder 12 is provided with a scale mark 16 for marking the length value. The scale mark 16 can assist the operator in observing the insertion depth of the tube body 11, making it safer to use.

[0033] In this embodiment, a structure for storing the tube body 11 is also provided. A positioning sleeve 131 is provided at the lower end of the liquid inlet pipe 13, which is sleeved on the tube body 11. A C-shaped pipe clamp 132 is fixed on the positioning sleeve 131, and the inner diameter of the pipe clamp 132 is matched with the lower end diameter of the tube body 11. A through hole is provided on the positioning sleeve 131 for the inflation tube 121 to pass through, so that the inflation tube 121 can be fixed. When packaging or storing the tube body 11, the tube body 11 can be bent, and then the end can be clamped and fixed on the pipe clamp 132, so as to ensure the stability of the tube body 11 and avoid bending during transportation.

[0034] Working principle: The utility model is an enema tube for treating ulcerative colitis. When in use, the tube body 11 is inserted into the anus of the patient, and the scale mark 16 can assist the operator to observe the insertion depth of the tube body 11. The operator injects the enema liquid through the liquid inlet tube 13, and the enema liquid can flow along the flow channel of the tube body 11 and finally flow out from the liquid outlet 14 to inject the enema liquid into the patient's body. The operator can repeatedly squeeze the inflation ball 123, thereby inflating and pressurizing the capsule cavity through the extension tube 124 and the inflation tube 121. The capsule cavity of the annular structure formed between the expansion capsule 12 and the inner capsule 15 can accommodate gas to expand the expansion capsule 12 outward and squeeze the inner capsule 15 inward, and then close the flow channel inside the tube body 11 through the inner capsule 15, and improve the sealing between the tube body 11 and the patient's skin through the expansion capsule 12, effectively reducing the reflux of the enema liquid.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
