Mouthful external end, the rectum anal tube end of flexible pipe body 1 is the front end of flexible pipe body 1, flexible pipe body 1 close to the external of anal orifice
End is the rear end of flexible pipe body 1.
A buffering and anti-delinking part 2 and a buffering and leakage barriers 3, buffering and anticreep are fixed on 1 outer wall of flexible pipe body
Portion 2 is located at 1 outer wall front of flexible pipe body, and buffering and leakage barriers 3 are located at 1 external rear wall of flexible pipe body, and buffering and anti-delinking part 2 are gentle
The sum of length is equal to the length in the front-back direction of flexible pipe body 1 in the front-back direction for punching and leakage barriers 3.Buffering and anti-delinking part 2 and buffering
And leakage barriers 3 are adhesively fixed on 1 outer wall of flexible pipe body by medical grade glue.Buffering and anti-delinking part 2 are elliposoidal or spherical shape
Air bag body, buffering and leakage barriers 3 are cylindrical balloon body.Buffering and anti-delinking part 2 and buffering and leakage barriers 3 are air bag independent of each other
Body.Buffering and the size of anti-delinking part 2 are greater than the size of buffering and leakage barriers 3.
The buffering and anti-delinking part 2 and buffering and leakage barriers 3 are separately connected a ventilation pipe 4.The buffering and anticreep
Portion 2 connect 4 front end of ventilation pipe be located at buffering and anti-delinking part 2 in and be fixed on 1 outer wall of flexible pipe body, it is described buffering and
Part of the ventilation pipe 4 that anti-delinking part 2 connects outside buffering and anti-delinking part 2 is out of shape along 1 outer wall of flexible pipe body and by buffering
And it between 1 outer wall of leakage barriers 3 and flexible pipe body and stretches out in outside 3 rear side of buffering and leakage barriers.Buffering and leakage barriers 3 connect logical
4 front end of feed channel is in buffering and leakage barriers 3 and is fixed on 1 outer wall of flexible pipe body, buffers and what leakage barriers 3 connected leads to
Part of the feed channel 4 outside buffering and leakage barriers 3 is located at the rear side of buffering and leakage barriers 3.What the buffering and anti-delinking part 2 connected
4 front end of ventilation pipe that 4 front end of ventilation pipe is connect with buffering and leakage barriers 3 is relatively fixed in 1 outer wall two sides of flexible pipe body.Institute
It states buffering and anti-delinking part 2 and there is inflation/deflation connector 5 in the rear end of ventilation pipe 4 that buffering and leakage barriers 3 are separately connected respectively, respectively
There is openable corking 6 on inflation/deflation connector 5.
The external end of the flexible pipe body 1 close to anal orifice is that rear end has blocking portion 7,1 one of blocking portion 7 and flexible pipe body
Connection.Blocking portion 7 is hollow horn structure, buffers and leakage barriers 3 are located at horn structure and 1 connecting position of flexible pipe body is close
Side.The rear end for the ventilation pipe 4 that buffering and anti-delinking part 2 and buffering and leakage barriers 3 are separately connected is oneself by horn structure
By holding.
An elastic sealing element 8 is fixed in the flexible pipe body 1.Elastic sealing element 8 is fixed in flexible pipe body 1 and loudspeaker
The position that structure, that is, blocking portion 7 connects, the elastic sealing element 8 in the position is buffered and leakage barriers 3 are surround, buffering and leakproof
Portion 3 is Chong Die with projection of the elastic sealing element 8 on flexible pipe body 1.The outer wall and 1 inner wall of flexible pipe body of the elastic sealing element 8
It is adhesively fixed, or is fixed by hot melting way and 1 inner wall of flexible pipe body, the position of elastic sealing element 8 by medical grade glue
Next to horn structure, horn structure internal diameter is big, therefore easily fixes elastic sealing element 8.Elastic sealing element 8 is elastic rubber
Piece.There is the endoscope passage 81 coaxial with flexible pipe body 1 at 8 center of elastic sealing element, and Sigmoidoscope is facilitated to pass through, endoscope passage 81 it is straight
Diameter is less than the outer diameter of Sigmoidoscope, can tightly encase Sigmoidoscope, and the friction between increase and Sigmoidoscope prevents Sigmoidoscope from deviating from and preventing
Only colon gas is spilt with liquid dung.
When in use, buffering and anti-delinking part 2 and buffering and leakage barriers 3 can be deflated retraction, buffering and anticreep
Portion 2 and the independent external snorkel 5 of buffering and leakage barriers 3, as needed, can adjust in real time buffering and anti-delinking part 2 and buffering and
Gas in leakage barriers 3, to adjust the size of buffering and anti-delinking part 2 and buffering and leakage barriers 3.Human body is placed into flexible pipe body 1
Anal canal position after, buffering and anti-delinking part 2 and buffering and leakage barriers 3 can according to need, be inflated, perform its own function.
Buffering and leakage barriers 3 are filled with air to form class cylindrical airbag, are bonded with anal canal, can be reduced the friction of Sigmoidoscope 100 Yu anal canal,
Cause patient uncomfortable so as to reduce, and squeezed by the elasticity of buffering and leakage barriers 3 can also prevent anal orifice gas leakage and
Liquid dung discharge；Buffering and anti-delinking part 2 when in use, after gas injection, form approximate sphericity or ellipsoid air vesicle, can be stuck in rectum
At anal canal, fixed function (the horn structure energy and anus of flexible pipe body 1 is formed with the horn structure (blocking portion 7) of flexible pipe body 1
Mouth buttocks is tightly bonded, and is blocked in around anal orifice, prevents flexible pipe body 1 from sliding into anal canal), when so that Sigmoidoscope 100 is mobile,
Still flexible pipe body 1 is able to maintain in anal canal position without shifting；Elastic sealing element 8 is located at 1 medial surface of flexible pipe body, Sigmoidoscope
100 can go through from the endoscope passage 81 of elastic sealing element 8, since the diameter of endoscope passage 81 is less than the outer of Sigmoidoscope 100
Diameter prevents Sigmoidoscope 100 from deviating from and preventing colon gas and liquid dung so as to the friction between the Sigmoidoscope 100 that increases and rub
It spills.Since the diameter of endoscope passage 81 is less than the outer diameter of Sigmoidoscope 100, elastic sealing element 8 can tightly encase Sigmoidoscope
100, in Sigmoidoscope 100 towards when sending in anus, so that 81 edge of endoscope passage of elastic sealing element 8 can follow 100 court of Sigmoidoscope
Interior movement and bending deformation (as shown in Figure 6), Sigmoidoscope 100 towards it is mobile outside anus when, 81 side of endoscope passage of elastic sealing element 8
Edge can follow Sigmoidoscope 100 to move and bending deformation (as shown in Figure 7) outwardly.
