[0014] The following further details the specific embodiments of the utility model with reference to the drawings.

[0015] By Figures 1 to 7Provided, including a rectangular shell 1, two connecting pipes 2 opposite to each other left and right are provided at the lower end of the rectangular shell 1. The upper end of the connecting pipe 2 is communicated with the inside of the rectangular shell 1 and the lower end is communicated with the outside. An annular inflatable column 3 is provided at the upper end of the rectangular shell 1. An inflatable cavity 4 with an opening facing outwards is opened on the inflatable column 3. The cross-section of the inflatable cavity 4 in the up-down direction is an inverted C shape. A liquid inlet pipe 5 with its lower end communicated with the upper end of the rectangular shell 1 is fixed inside the inflatable column 3. An annular groove 6 is provided at the upper end of the liquid inlet pipe 5. The lower side of the groove 6 can be communicated with the inflatable cavity 4. An expandable airbag 7 for blocking the outside of the groove 6 is provided on the liquid inlet pipe 5. An annular push column 8 is slidably connected to the outside of the inflatable column 3. The push column 8 contacts the liquid inlet pipe 5. A piston rod 9 having the same cross-sectional shape as the inflatable cavity 4 is provided inside the push column 8. The push column 8 is in close fit with the outside of the inflatable column 3.

[0016] In order to control the communication between the connecting pipe 2 and the liquid inlet pipe 5, two L-shaped baffles 10 opposite to each other left and right and slidably connected inside the rectangular shell 1 are provided. The baffle 10 can block the corresponding connecting pipe 2. A screw rod 11 is threadedly connected to the front end of the baffle 10. The rear end of the screw rod 11 is rotatably connected to the rectangular shell 1.

[0017] In order to facilitate restricting the sliding position of the push column 8, a plurality of limiting grooves 12 evenly distributed in the up-down direction and opening backwards are opened on the rear side of the inflatable column 3. A limiting rod 13 is hinged to the rear end of the push column 8 through a shaft. The lower end of the limiting rod 13 can be inserted into the limiting groove 12.

[0018] In order to facilitate the swinging of the limiting rod 13, a yielding groove 14 opening backwards is opened on the rear side of the push column 8. The front side of the yielding groove 14 can be communicated with the limiting groove 12. The upper side of the limiting rod 13 is connected to the yielding groove 14 through a V-shaped elastic sheet 15.

[0019] In order to better prevent the enema liquid from overflowing outwards, an oval elastic blocking block 16 is provided at the upper end of the push column 8. The inner side of the elastic blocking block 16 contacts the liquid inlet pipe 5.

[0020] In order to communicate the groove 6 with the inflatable cavity 4, connecting grooves 17 in the up-down direction are respectively opened on the left and right sides of the liquid inlet pipe 5. The upper end of the connecting groove 17 is communicated with the groove 6 and the lower end is communicated with the inflatable cavity 4 through an L-shaped air delivery pipe 18.

[0021] When the present utility model is in use, rotate the left screw rod 11 clockwise so that the left baffle does not block the corresponding connecting pipe 2. At this time, the medical staff can insert the upper end of the liquid inlet pipe 5 into the patient's intestine through the anus. When the expandable airbag 7 enters the inside of the patient's anus, press the upper side of the limiting rod 13 forward to move the lower end of the limiting rod 13 out of the limiting groove 12 and squeeze the elastic sheet 15, and then move the push column 8 upwards. The push column 8 pushes the gas in the inflatable cavity 4 upwards through the piston rod 9;

[0022] The gas in the inflatable cavity 4 flows through the air supply pipe 18 and the connecting groove 17 into the groove 6, and then inflates the expandable latent airbag. The inflatable airbag 7 expands annularly outward and supports and seals the inner side of the patient's anus to prevent the enema fluid in the long swing from flowing out. At the same time, the push column 8 pushes the elastic shielding block 16 to squeeze the outer side of the patient's anus. Through the action of the inflatable airbag 7 and the elastic shielding block 16, it prevents the patient from having an overflow.

[0023] Then the medical staff releases the limit rod 13. Under the action of the elastic sheet 15, the limit rod 13 is inserted into the limit groove 12 to limit the position of the push column 8. Then the medical staff uses a syringe to connect the left connecting pipe 2 to perform an enema on the patient. After the infusion of the medicinal liquid is completed, the screw rod 11 on the left can be rotated counterclockwise so that the baffle on its corresponding side blocks the connecting pipe 2 on its corresponding side to prevent the enema fluid from flowing out. If diversion is required, only the screw rod 11 on the right needs to be rotated to control the movement of the baffle on its corresponding side, and the connection between different connecting pipes 2 and the liquid inlet pipe 5 can be achieved.

[0024] The utility model has a clever structure and is convenient to use. By setting an inflatable column, an inflatable cavity, a piston rod, a push column, an inflatable airbag and an elastic shielding pad, when performing enema treatment on a patient, after inserting the liquid inlet pipe into the patient's anus and injecting the enema fluid, it can shield the inner side of the patient's anus to prevent the patient from having an overflow of the enema fluid, avoiding the waste of the enema fluid and the pollution of the bed sheets and clothes. At the same time, it is provided with a connecting pipe and a shielding baffle, which can control the connection between the liquid inlet pipe and the connecting pipe during enema treatment, realize the closing of the liquid inlet pipe and the diversion effect of the enema fluid, which is beneficial to the operation and use of medical staff. This structure is simple, easy to operate, novel in conception and strong in practicability.
