[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The utility model provides an enema for patients with inflammatory bowel disease, comprising a liquid storage bottle 1, a connecting catheter 2 and a hose 3. Both ends of the liquid storage bottle 1 are provided with a liquid infusion tube 5, one end of the liquid infusion tube 5 is provided with a ball valve. Through the arrangement of the two liquid infusion tubes 5, the liquid storage bottle 1 can be infused from multiple directions, thereby improving the convenience of using the liquid storage bottle 1. A piston 23 is movably connected to the inner cavity of the liquid storage bottle 1, and an extrusion rod 10 is fixedly connected to the middle part of one side of the piston 23. The other end of the extrusion rod 10 passes through the liquid storage bottle 1 and extends to the outside of the liquid storage bottle 1. The extrusion rod 10 is movably connected to the liquid storage bottle 1. Through the arrangement of the extrusion rod 10 and the piston 23, medical staff can drive the piston 23 to squeeze the liquid in the liquid storage bottle 1 through the extrusion rod 10, so that the liquid in the liquid storage bottle 1 can be squeezed out, and the piston 23 divides the inner cavity of the liquid storage bottle 1 into two chambers. When the piston 23 gradually approaches one liquid infusion tube 5, the medical staff can infuse liquid through the other liquid infusion tube 5 away from the piston 23, so that the enema achieves the purpose of infusing liquid during use, thereby improving the adaptability of the enema.

[0024] A first outlet 20 is provided at one end of the liquid storage bottle 1, through which the enema liquid in the liquid storage bottle 1 can be squeezed out. A connecting channel 21 is provided on the side wall of the liquid storage bottle 1. The end of the connecting channel 21 away from the first outlet 20 is a liquid inlet end 18, through which the connecting channel 21 communicates with the inner cavity of the liquid storage bottle 1. The end of the connecting channel 21 closer to the first outlet 20 is a second outlet 19, through which the connecting channel 21 communicates with the outside world, through which the enema liquid in the liquid storage bottle 1 can be squeezed out.

[0025] One end of the liquid storage bottle 1 near the first outlet 20 is movably connected to a rotating plate 6, and the middle part of the end of the liquid storage bottle 1 near the first outlet 20 is fixedly connected to a positioning ring 8. A positioning groove 9 is provided in the middle part of the rotating plate 6, and the rotating plate positioning ring 8 is movably connected to the inner cavity of the positioning groove 9. Through the setting of the positioning ring 8 and the positioning groove 9, the rotating plate 6 and the liquid storage bottle 1 are in a movably connected state, and a limiting block is fixed on one side of the positioning ring 8, and a limiting groove adapted to the limiting block is provided on one side of the positioning groove 9. Through the setting of the limiting block and the limiting groove, the position of the rotating plate 6 can be positioned.

[0026] The rotating plate 6 is provided with a latch hole 7, the inner cavity of which is provided with a one-way valve. When the latch hole 7 is aligned with the first outlet 20, the stopper contacts one side of the stopper groove, allowing the liquid in the liquid storage bottle 1 to be discharged through the first outlet 20, the latch hole 7 to be separated from the second outlet 19, and the outlet end of the connecting flow channel 21 to be sealed by the rotating plate 6. When the latch hole 7 is aligned with the second outlet 19, the stopper contacts the other side of the stopper groove, allowing the liquid in the liquid storage bottle 1 to be discharged through the connecting flow channel 21, and the latch hole 7 to be separated from the first outlet 20, which is sealed by the rotating plate 6. With this arrangement, medical personnel can change the position of the latch hole 7 by rotating the rotating plate 6, thereby changing the method of discharging the enema liquid from the liquid storage bottle 1.

[0027] The one-way valve includes a liquid-permeable mesh plate 22 adapted to the clamping hole 7 and a cross-valve 17 fixedly connected to the liquid-permeable mesh plate 22 on one side of the liquid storage bottle 1. When the enema liquid is squeezed out, the enema liquid squeezes the cross-valve 17, causing the cross-valve 17 to deform, allowing the enema liquid to be discharged through the one-way valve. When the restriction on the cross-valve 17 is released, the cross-valve 17 blocks the liquid-permeable mesh plate 22, preventing the liquid in the connecting catheter 2 from flowing back.

[0028] One end of the connecting catheter 2 is engaged with the clamping hole 7, and the other end of the connecting catheter 2 is engaged with the hose 3. The other end of the hose 3 is evenly provided with a drainage port 16. Another one-way valve is provided in the inner cavity of the other end of the hose 3. The other one-way valve includes a liquid-permeable mesh plate 22 fixedly connected to the inner wall of the hose 3. A cross valve 17 is fixedly connected to the side of the liquid-permeable mesh plate 22 close to the drainage port 16. The provision of the other one-way valve can prevent external liquid from flowing in the hose 3.

[0029] By providing the two one-way valves, it is possible to prevent external liquid from contaminating the enema liquid in the enema device, so that the liquid in the liquid storage bottle 1 can be reused.

[0030] The outer ring of the hose 3 is movably connected to the sealing plug 4, and the sealing plug 4 and the hose 3 are sealed by an expansion ring 15. A tail tube 11 is provided in the middle of the sealing plug 4, and the inner wall of the tail tube 11 is fixedly connected to the expansion ring 15. The end of the tail tube 11 away from the sealing plug 4 is fixedly connected to the airbag 13, and the inner cavity of the airbag 13 is in a state of communication with the inner cavity of the expansion ring 15. A threaded tube 12 is fixed to the end of the sealing plug 4 close to the airbag 13, and the inner cavity of the threaded tube 12 is threadedly connected to the rotating tube 14. The inner wall of the rotating tube 14 is fixedly connected to an extrusion sheet, which is located between the airbag 13 and the sealing plug 4. Through the configuration of the sealing plug 4, the sealing plug 4 can be inserted into the patient's body to seal the enema area, avoiding the situation where water is injected and waste is discharged at the same time. After the enema is completed, the medicine is maintained in the patient's body. Medical staff can change the position of the squeezing plate by rotating the rotating tube 14. When the squeezing plate squeezes the airbag 13, the liquid in the airbag 13 can enter the inner cavity of the expansion ring 15. The volume of the expansion ring 15 becomes larger, which can block the inner cavity of the tail tube 11, making it easier to block the liquid medicine, or block the gap between the sealing plug 4 and the hose 3 to avoid leakage during the enema process.

[0031] The end of the hose 3 near the drain port 16 is spherical, and the end of the sealing plug 4 is provided with a rounded corner, which facilitates the insertion of the hose 3 and the sealing plug 4 into the patient's body. The hose 3 is provided with a scale to facilitate medical staff to control the length of the hose 3 inserted into the patient's body.

[0032] In summary, when the enema device for patients with inflammatory bowel disease is used, the enema liquid is injected into the liquid storage bottle 1 through the liquid infusion tube 5. The specific operation is as follows: the medical staff inserts the end of the liquid infusion tube 5 into the enema liquid, and the piston 23 is tightly fitted with the inner wall of the liquid storage bottle 1. The ball valve is opened, and the medical staff drives the piston 23 by squeezing the rod 10. When the piston 23 moves, the enema liquid can be drawn into the liquid storage bottle 1. After the amount of enema liquid in the liquid storage bottle 1 is appropriate, the medical staff closes the ball valve. One end of the connecting catheter 2 is clamped to the clamping hole 7, and the other end of the connecting catheter 2 is clamped to the hose 3, and the sealing plug 4 is put on the hose 3. After the medical staff inserts the hose 3 into the body of the patient with inflammatory bowel disease to an appropriate length, the medical staff moves the sealing plug 4 through the tail tube 11 until the sealing plug 4 is inserted into the patient's body. The sealing plug 4 blocks the patient's anus. After the sealing plug 4 is inserted, the medical staff rotates the rotating tube 14. During the rotation of the rotating tube 14, the extrusion piece is driven to squeeze the airbag 13. The gas in the airbag 13 is squeezed into the inner cavity of the expansion ring 15. The volume of the expansion ring 15 expands until it is tightly fitted with the hose 3. The gap between the sealing plug 4 and the hose 3 is sealed, thereby improving the sealing effect of the sealing plug 4. Medical staff drives the piston 23 to move by squeezing the rod 10, and the enema liquid in the liquid storage bottle 1 can be discharged into the inner cavity of the connecting catheter 2 through the first outlet 20 or the second outlet 19 aligned with the clamping hole 7. The liquid in the connecting catheter 2 enters the hose 3 and is injected into the enema area through the discharge port 16 provided on the hose 3. After the enema, the one-way valve intercepts the waste liquid to prevent the waste liquid from flowing back.

[0033] After the enema is completed, the medical staff removes the hose 3 and the sealing plug 4 from the patient's body. If the enema liquid needs to be kept in the patient's body for a period of time, the medical staff can directly disconnect the connection between the hose 3 and the connecting catheter 2, and the sealing plug 4 seals the patient's enema area to facilitate the retention of the enema liquid. If the hose 3 needs to be removed, the medical staff pulls the hose 3 outward. When the hose 3 moves into the inner cavity of the tail tube 11, the medical staff continues to rotate the rotating tube 14. The rotating tube 14 drives the extrusion piece to continue to squeeze the airbag 13, and the volume of the expansion ring 15 expands. At this time, the expansion ring 15 can seal the inner cavity of the tail tube 11, and the sealing plug 4 continues to seal the enema area of the patient. The medical staff continues to pull the hose 3, and the hose 3 can be removed.
