[0029] Please refer to Figures 1-11 , the present invention provides a technical solution: an enema device for ulcerative colitis, including an operation table 1. On the rear side of the upper surface of the operation table 1, reciprocating lifting components 2 are symmetrically and fixedly installed on the left and right. A seat 4 is rotatably connected between the inner sides of the two reciprocating lifting components 2 through a first rotating component 3. An enema through groove 5 is correspondingly formed on the seat surface of the seat 4. Through the seat 4 and the enema through groove 5, it is convenient for patients to sit and lie down for enema treatment. Electric lifting rods 6 are symmetrically and fixedly installed on the left and right in the middle of the upper surface of the operation table 1. The tops of the two electric lifting rods 6 are respectively fixedly installed with a first lifting plate 7 and a second lifting plate 8. A clamping and fixing component 10 that contacts and clamps the outer side of the enema tube 11 is rotatably connected between the inner sides of the first lifting plate 7 and the second lifting plate 8 through a second rotating component 9. By driving the lifting and moving of the first lifting plate 7 and the second lifting plate 8 by the two electric lifting rods 6, the height of the second rotating component 9 and the clamping and fixing component 10 can be adjusted up and down according to the usage needs. Liquid medicine holes 12 are evenly distributed at the rear end of the outer side of the enema tube 11. The front end of the enema tube 11 is fixedly connected with a syringe 17 through a long hose 16. Through the enema tube 11, the liquid medicine holes 12 and the syringe 17, enema injection of liquid medicine can be carried out. A shielding cover 18 corresponding to the enema through groove 5 is movably sleeved on the outer side of the enema tube 11 at a position between the liquid medicine holes 12 and the clamping and fixing component 10. Through the shielding cover 18, shielding protection can be carried out during enema operation, avoiding the discharge of excited excrement of patients from affecting medical staff and equipment, and also avoiding the splashing of liquid medicine during the enema process and when the enema tube 11 is pulled out.

[0030] Further, as Figure 2As shown in the figure, the reciprocating lifting assembly 2 includes a fixed plate 201, a mounting groove 202, a guide rod 203, a slider 204, a lead screw 205 and a reciprocating motor 206. The fixed plate 201 is fixedly installed on the upper surface of the operating table 1. An upper part inside the fixed plate 201 is provided with the mounting groove 202. The guide rod 203 is fixedly installed between the top and bottom inner walls of the mounting groove 202. The lead screw 205 is rotatably connected between the top and bottom inner walls of the mounting groove 202 through bearings. The lead screw 205 is parallel to the guide rod 203.

By driving the rotation of the lead screw 205 through the reciprocating motor 206, the lifting movement of the slider 204 can be driven, and the height of the seat 4 can be adjusted up and down according to the usage requirements.

[0031] Further, as Figure 4 shown, the first rotating assembly 3 includes a first rotating shaft 301 and a first rotating motor 302. The lower parts on the left and right sides of the backrest of the seat 4 are respectively fixedly installed with the first rotating shafts 301. The outer ends of the two first rotating shafts 301 are respectively rotatably connected to the middle parts inside the two sliders 204 between the lead screw 205 and the guide rod 203 through bearings. The first rotating motor 302 is fixedly installed on the outside of one of the sliders 204. The output shaft of the first rotating motor 302 is fixedly connected to the outer end of one of the first rotating shafts 301. By driving the rotation of the first rotating shaft 301 through the first rotating motor 302, the angle of the seat 4 can be adjusted according to the usage requirements of different patients and different medical staff during enema treatment.

The output shaft of the second rotating motor 905 is fixedly connected to the center of the side surface of the driving gear 904. The driving gear 904 is correspondingly and adaptively meshed with the driven gear 903. By the complementary telescopic adjustment of the two first electric telescopic rods 902, the left and right positions of the clamping and fixing assembly 10 and the enema tube 11 can be adjusted horizontally. By driving the rotation of the driving gear 904 through the second rotating motor 905, and then driving the rotation of the driven gear 903 and the second rotating shaft 901, the inclination angle of the enema tube 11 can be adjusted according to the needs.

[0033] Further, as Figure 8 shown, the clamping and fixing assembly 10 includes a connecting plate 101, a mounting plate 102, a clamping block 103, a second electric telescopic rod 104, and an arc-shaped groove 105. The left and right sides of the connecting plate 101 are respectively fixedly connected to the inner ends of the two first electric telescopic rods 902. Symmetrically and fixedly installed on the left and right sides of the upper surface of the connecting plate 101 are mounting plates 102. Symmetrically and fixedly installed on the inner sides of the two mounting plates 102 are second electric telescopic rods 104. Symmetrically and fixedly installed on the inner ends of the two second electric telescopic rods 104 are clamping blocks 103. Symmetrically formed on the inner sides of the two clamping blocks 103 are arc-shaped grooves 105 that are correspondingly and movably clamped to the outside of the enema through groove 5. By driving the telescopic movement of the two clamping blocks 103 through the two second electric telescopic rods 104, it is convenient to clamp and fix the outside of the enema tube 11 through the two clamping blocks 103 and the two arc-shaped grooves 105 on their inner sides, reducing the burden of continuous hand-held operation.

[0034] Further, as Figure 10 shown, a flexible ball 13 is fixedly installed at the rear end of the enema tube 11. The flexible ball 13 can reduce the pain of the device when inserted deep into the patient's rectum.

[0035] Further, as Figure 10 shown, a one-way valve 15 is provided between the front end of the enema tube 11 and the rear end of the long hose 16. The one-way valve 15 can assist in preventing the backflow of the liquid medicine in the enema tube 11 during the enema operation. The rear end of the one-way valve 15 is communicated with the front end of the enema tube 11, and the front end of the one-way valve 15 is communicated with the rear end of the long hose 16. The front end of the long hose 16 is fixedly communicated with the injection port of the syringe 17. A limit ring 14 is correspondingly and fixedly installed at a position on the outside of the enema tube 11 near the one-way valve 15 at the front end, which plays an auxiliary role in limiting and protecting.

[0036] Further, as Figure 4 shown, a circular card slot 20 is formed at the bottom of the seat surface of the seat 4 at a position outside the enema through groove 5. As Figure 11 shown, the shape of the shielding cover 18 is a horn-shaped structure that is thinner at the front and thicker at the rear. An annular card strip 19 that is correspondingly and movably clamped is integrally provided at the rear end of the shielding cover 18. Through the movable clamping of the annular card strip 19 and the circular card slot 20, it is convenient for the installation, protection, and disassembly of the shielding cover 18.

[0037] Further, as Figure 3As shown in the figure, a first U-shaped bracket 21 is fixedly installed on the upper part of the rear side of the backrest of the seat 4. When the seat 4 rotates and reclines for adjustment, the first U-shaped bracket 21 plays a role in auxiliary limit support and auxiliary protection, so that its reclining rotation angle does not exceed 90 degrees (that is, the backrest of the seat 4 can only rotate backward to the horizontal state). On the left and right sides of the bottom of the seat surface of the seat 4, second U-shaped brackets 22 are symmetrically and fixedly installed. When the seat 4 rotates forward and the seat surface of the seat 4 returns to the horizontal state, the second U-shaped brackets 22 play a role in auxiliary limit support and auxiliary protection. Rubber pads 23 are respectively fixedly installed on the rear side of the horizontal end of the first U-shaped bracket 21 and the bottoms of the horizontal ends of the two second U-shaped brackets 22, and the rubber pads 23 play a role in auxiliary buffering.
