[0037] Combine the following Figure 1-Figure 8 The intestinal irrigation device for gastroenterology of the present invention is described.

[0038] like Figure 1-Figure 8 As shown, in one embodiment, a gastroenterology intestinal irrigation device comprises:

[0039] An insert hose 100, one end of which is hemispherical, and the other end of which is fixedly connected to a connecting handle 110, and the other end of which is fixedly connected to a connecting pipe 130, and the other end of which is connected to a discharge pipe 120, and the discharge pipe 120 is used to discharge waste liquid in cooperation with a negative pressure suction device, and a connecting cavity 1101 is provided inside the connecting handle 110, and a suction channel 150 is provided inside the insert hose 100, and a flow channel 160 is provided inside the insert hose 100 in an annular distribution with the suction channel 150 as the center, and the flow channel 160 is connected to the connecting cavity 1101, and an introduction pipe 140 connected to the connecting cavity 1101 is provided on the surface of the connecting handle 110, and the introduction pipe 140 is used for injecting flushing liquid;

[0040] The surface of the connecting handle 110 is provided with a mounting channel connected to the connecting pipe 130, and the suction channel 150 is connected to the connecting pipe 130 through the mounting channel;

[0041] An auxiliary component 200, which is arranged on the surface of the insertion hose 100 and close to one end of the hemispherical arrangement, and is used to improve the flushing effect;

[0042] An adjusting component 300, wherein the adjusting component 300 is disposed inside the suction channel 150, and the adjusting component 300 is used to control the opening and closing of the suction channel 150;

[0043] Among them, the auxiliary component 200 includes an adjustment bag 240 embedded and installed on the surface of the insertion hose 100. The adjustment bag 240 can swell and fill the gap between the insertion hose 100 and the intestine, so that the flushing liquid will not flow out along the insertion hose 100. The insertion hose 100 is hemispherically arranged at one end with a ring-shaped discharge hole 230.

[0044] When the insertion hose 100 is inserted into the body, the hemispherical setting of its end can facilitate the insertion of the insertion hose 100 and reduce discomfort caused during insertion. By injecting flushing liquid into the introduction tube 140, it can be injected into the interior of the connecting cavity 1101 and introduced into the flow channel 160, and finally discharged through the discharge hole 230 for flushing the inside of the intestine.

[0045] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 8 As shown, the surface of the regulating capsule 240 is connected with evenly distributed outlet tubes 220 and flow guide tubes 210 , the other end of the flow guide tubes 210 is connected to the flow channel 160 , and the other end of the outlet tubes 220 is connected to the discharge hole 230 .

[0046] The inner wall of the guide tube 210 is fixedly connected with a connecting ring 2101 , and a shielding membrane 2102 is provided on the side of the connecting ring 2101 close to the regulating capsule 240 . The surface of the shielding membrane 2102 is fixedly connected with a connecting rod 2103 , and the connecting rod 2103 is rotatably connected to the inner wall of the connecting ring 2101 .

[0047] A spring 2104 is fixedly connected to the surface of the connecting rod 2103 , and the other end of the spring 2104 is fixedly connected to the inner wall of the connecting ring 2101 .

[0048] The inner wall of the outlet pipe 220 is fixedly connected with a mounting sleeve 2201 , and the inner wall of the mounting sleeve 2201 is slidably connected with a blocking block 2203 . The diameter of the blocking block 2203 is equal to the inner diameter of the mounting sleeve 2201 .

[0049] The blocking block 2203 is fixedly connected to a side thereof close to the regulating capsule 240 with an adjusting rod 2202. The other end of the adjusting rod 2202 passes through the mounting sleeve 2201 and the outlet tube 220 in sequence and is fixedly connected to the inner wall of the regulating capsule 240. The diameter of the adjusting rod 2202 is smaller than that of the blocking block 2203.

[0050] The flushing liquid injected into the flow channel 160 can be injected into the interior of the guide tube 210. In this process, the pressure of the flushing liquid flowing is used to overcome the elastic force of the spring 2104, so that the flushing liquid pushes the shielding diaphragm 2102 to flip around the connecting rod 2103, so that the flushing liquid can pass through the gap between the connecting ring 2101 and the shielding diaphragm 2102 and enter the interior of the regulating capsule 240. As more flushing liquid is injected into the regulating capsule 240, the regulating capsule 240 can gradually swell, and the swollen regulating capsule 240 can fill the gap between the insertion hose 100 and the intestine, and in the process of the swelling of the regulating capsule 240 It can gradually drive the adjustment rod 2202 to move, and drive the blocking block 2203 to slide along the inner wall of the mounting sleeve 2201 until it is separated from the mounting sleeve 2201. The subsequently injected flushing liquid can be discharged through the discharge hole 230, and the bulging adjustment bag 240 can increase the contact area with the inside of the intestine, thereby avoiding the recoil force formed during the flushing liquid discharge process causing the insertion hose 100 to slip out, effectively improving the flushing effect, and can reduce the situation where part of the flushing liquid flows out along the surface of the insertion hose 100, thereby improving the utilization rate of the flushing liquid and thereby improving the flushing effect.

[0051] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, the adjustment component 300 includes a mounting block 330 fixedly connected to the inner wall of the suction channel 150, a suction hole is opened on the surface of the mounting block 330, a blocking rod 340 is arranged inside the suction hole, one end of the blocking rod 340 passes through the mounting block 330 and is fixedly connected to the mounting rod 350, and the other end of the mounting rod 350 is fixedly connected to the connecting plate 370.

[0052] A spring 360 is fixedly connected to the surface of the connecting plate 370 , and the other end of the spring 360 is fixedly connected to the surface of the connecting plate 370 .

[0053] The adjustment assembly 300 also includes a connecting column 380 fixedly connected to the surface of the connecting tube 130, the inner wall of the connecting column 380 is threadedly connected to a screw 390, one end of the screw 390 passes through the connecting column 380 and is fixedly connected to a knob 3010, the other end of the screw 390 is fixedly connected to an adjustment rope 320, the other end of the adjustment rope 320 passes through the connecting column 380, the connecting tube 130, the connecting handle 110 and the insertion hose 100 in sequence and is fixedly connected to the surface of the connecting plate 370.

[0054] The inner wall of the connecting tube 130 is fixedly connected with a guide protrusion 310 , and the guide protrusion 310 is used to reduce the friction force at the corner of the adjusting rope 320 .

[0055] After flushing is completed, the discharge pipe 120 can be connected to a negative pressure suction device. The specific negative pressure suction device can be a negative pressure suction machine such as a suction pump, which is connected to the pipeline and then communicated with the discharge pipe 120. The discharged waste liquid should be collected and processed uniformly to avoid pollution.

[0056] When suction is required, the knob 3010 can be rotated to drive the screw 390 to gradually extend from the inside of the connecting column 380. During this process, the adjusting rope 320 can be driven to pull the connecting plate 370 toward the direction of the connecting handle 110, thereby driving the blocking rod 340 to separate from the suction hole. During this process, the spring 360 can be stretched. The setting of the spring 360 is used to keep the blocking rod 340 able to block the suction hole under normal circumstances, thereby avoiding the situation where part of the flushing fluid is directly discharged through the suction hole during the flushing process, thereby effectively improving the utilization rate of the flushing fluid and thus improving the flushing effect.

[0057] The guide protrusion 310 is provided to reduce the friction when the adjustment rope 320 moves, thereby avoiding the adjustment rope 320 from breaking during the movement.

[0058] Working principle: When the insertion hose 100 is inserted into the body, the hemispherical setting of its end can facilitate the insertion of the insertion hose 100 and reduce the discomfort caused during insertion. By injecting flushing liquid into the introduction tube 140, it can be injected into the interior of the connecting cavity 1101 and introduced into the flow channel 160. The flushing liquid injected into the flow channel 160 can be injected into the interior of the guide tube 210. In this process, the pressure of the flushing liquid flowing is used to overcome the elastic force of the spring 2104, so that the flushing liquid pushes the shielding diaphragm 2102 to flip around the connecting rod 2103, so that the flushing liquid can pass through the gap between the connecting ring 2101 and the shielding diaphragm 2102 and enter the interior of the regulating capsule 240. As the amount of flushing liquid injected into the regulating capsule 240 increases, the regulating capsule 240 can gradually swell, and the swollen regulating capsule 240 can fill the gap between the insertion hose 100 and the intestine, and the regulating capsule 24 During the swelling process, the regulating rod 2202 can be gradually driven to move, and the blocking block 2203 can be driven to slide along the inner wall of the mounting sleeve 2201 until it is separated from the mounting sleeve 2201. The flushing liquid injected subsequently can be discharged through the discharge hole 230, and the bulging regulating bag 240 can increase the contact area with the inside of the intestine, so as to avoid the recoil force formed during the flushing liquid discharge process causing the insertion hose 100 to slip out, thereby effectively improving the flushing effect, and can reduce the situation where part of the flushing liquid flows out along the surface of the insertion hose 100, thereby improving the utilization rate of the flushing liquid, and thus improving the flushing effect. By setting the regulating component 300, the blocking rod 340 can be kept able to block the suction hole under normal conditions, thereby avoiding the situation where part of the flushing liquid is directly discharged through the suction hole during the flushing process, thereby effectively improving the utilization rate of the flushing liquid, and thus improving the flushing effect.

[0059] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
