The intestinal lavage fluid passes through between the convex blocking contact 153 and the blocking hole 154, the convex blocking contact 153 can pass through the arc surface 155 and the blocking hole 154 are tightly attached to prevent the intestinal lavage fluid in the liquid storage box body 11 from continuously flowing out until the intestinal lavage fluid passes through the next closing-in.
When the expansion claws 14 are folded in the distal direction or the tank body 11 is pressed, the stopper projection 151 is disengaged from the stopper recess 152.
The working process of the plugging portion 15 is as follows: when the intestinal lavage liquid is filled, each expansion claw 14 is folded towards the far end direction, so that the plugging part 15 is opened;
when the colonoscope is inserted into the intestinal tract, each expansion claw 14 is folded towards the proximal direction and extrudes the liquid storage box body 11, so that the intestinal lavage liquid passes through the plugging part 15 and is sprayed to the contact part of the expansion claws 14 and the intestinal tract;
when the colonoscope exits the intestinal tract, each of the expansion claws 14 is folded in the distal direction, so that the blocking portion 15 is opened and the intestinal lavage fluid in the liquid storage tank body 11 is poured out.
In this embodiment, the purpose of the arc surface 155 is to ensure the attachment stability between the blocking protrusion 153 and the blocking hole 154, and avoid the leakage of the intestinal lavage fluid in the liquid storage box 2, specifically, as the intestinal lavage fluid in the liquid storage box 11 is continuously reduced, an angle may be formed between the blocking protrusion 153 and the blocking hole 154, so that the matching process between the blocking protrusion 153 and the blocking hole 154 may be changed from line contact to point contact, and thus the attachment effect between the blocking protrusion 153 and the blocking hole 154 is poor, and the intestinal lavage fluid in the liquid storage box 11 may accidentally leak, and the application makes the blocking protrusion 153 always attach to the blocking hole 154 by setting the arc surface 155, so as to ensure that the intestinal lavage fluid in the liquid storage box 11 does not leak.
The liquid through tube 12 is arranged on the distal side of the hinge joint of the expansion claw 14 and the expansion head 1. The liquid-passing tube 12 can guide the developer to pass through the intestinal tract or exhaust the gas in the intestinal tract.
In order to achieve the above effect, the liquid pipe 12 is fixedly connected to the expansion claw 14 and the expansion head 1, respectively. Specifically, the liquid passing tube 12 and the expansion head 1, and the liquid passing tube 12 and the expansion claw 14 are fixed by a positioning ring 122. Two positioning rings 122 are located on the upper and lower sides of the tank body 11. The liquid flowing pipe 12 is a turning section 121 with the fixing position of the liquid flowing pipe 12 and the expanding head 1 and the fixing position of the liquid flowing pipe 12 and the expanding claw 14, and the turning section 121 can be bent when the expanding claw 14 is turned over and the turning section 121 can block the developer or gas in the liquid flowing pipe 12 when being bent through the arrangement of the two positioning rings 122. In this way, when the intestinal lavage fluid is filled into the intestinal tract, the expansion claw 14 is folded towards the distal end, and the turning section 121 is conducted, so that the developing agent is introduced into the intestinal tract. When the colonoscope is inserted into the intestine, the turning segment 121 is blocked; when the colonoscope exits the intestinal tract, the turning section 121 is conducted, and the air in the intestinal tract is sucked out through the liquid through tube 12. In addition, when the colonoscope exits the intestinal tract, the turning section 121 pushes the liquid storage box body 11 to separate the blocking protrusion 153 from the blocking device opening 154, so as to ensure that the intestinal lavage liquid in the liquid storage box body 11 flows out.
In this embodiment, when the dilating plug 1 exits from the intestinal tract, the angle of the dilating claws 14 turning towards the distal end is changed continuously due to the folds of the intestinal tract, and then the bending degree of the turning sections 121 on the liquid passing tube 12 is also different, i.e. the flow rate in the liquid passing tube 12 is changed, so that the flow rate in the liquid passing tube 12 can be automatically adjusted to adapt to the fact that the dilating plug 1 exits from the intestinal tract.
