Detailed Description
The technical scheme of the invention is further described below by the specific embodiments with reference to the accompanying drawings.
A ventilator pipeline for preventing condensate water from flowing backwards comprises a connecting pipe body 1 and a water collecting device 2;
the connecting pipe body 1 comprises a rotating pipe 11;
the water collecting device 2 comprises a water collecting cup 21, a supporting body 22, a water blocking pipe 23 and a backflow preventing assembly 24;
the support body 22 includes a placement tube 221 and a cover body 222; the cover 222 is connected to the placing pipe 221, and the cover 222 is communicated with the placing pipe 221; the placing pipe 221 is disposed in the rotating pipe 11;
the water collection cup 21 is connected to the cover 222; the backflow prevention assembly 24 is arranged in the water collection cup 21 and is used for preventing condensate water collected in the water collection cup 21 from flowing backwards;
the water blocking pipe 23 is disposed in the placement pipe 221; the water blocking pipe 23 includes a cylindrical portion 231 and circular truncated cones 232 provided at both ends of the cylindrical portion 231;
one end of the circular truncated cone 232, which is close to the middle of the water blocking pipe 23, is a water blocking end 2321, the other end of the circular truncated cone 232 is a water inlet end 2322, and the outer diameter from the water inlet end 2322 of the circular truncated cone 232 to the water blocking end 2321 is continuously increased; the outer diameter of the cylindrical portion 231 is smaller than or equal to the outer diameter of the water inlet end 2322 of the truncated cone 232; the water stop 2321 has an outer diameter smaller than an inner diameter of the placement tube 221.
When in use, gas enters the other end from one end of the connecting pipe body 1 to realize the transportation of the gas, and condensed water in the gas path can continuously flow along the inner wall of the placing pipe 221, and as the outer diameter of the water blocking end 2321 of the round table part 232 is smaller than the inner diameter of the placing pipe 221, a certain gap exists between the water blocking pipe 23 and the placing pipe 221 as a whole, so that the condensed water can smoothly flow along the inner wall of the placing pipe 221 until flowing to the position where the cover 222 and the placing pipe 221 mutually penetrate, and finally the condensed water flows into the water collecting cup 21.
In order to prevent condensate water from flowing back into the rotary pipe 11, the water collecting cup 21 is provided with the backflow preventing assembly 24, and the probability of backflow of condensate water in the water collecting cup 21 can be effectively reduced. And even when the ventilator circuit turns over, the condensed water of the water collecting cup 21 has a chance to enter the position where the cover 222 is penetrated by the placing pipe 221, the condensed water is difficult to flow back into the rotating pipe 11, because the outer diameter of the water blocking end 2321 of the round table portion 232 is only slightly smaller than the inner diameter of the placing pipe 221, that is, only a small gap exists between the water blocking end 2321 of the round table portion 232 and the placing pipe 221, the condensed water can be effectively prevented from flowing out rapidly, and because the connecting pipe body 1 is always introduced with air, a certain air pressure exists in the connecting pipe body 1, and under the action of the air pressure, the condensed water is more difficult to flow out from the gap between the water blocking end 2321 and the placing pipe 221, so that the ventilator circuit of the present application can effectively prevent the condensed water from flowing out.
Further, the connection between the cover 222 and the placing pipe 221 is through the water inlet hole 223;
the water inlet hole 223 has a width in the axial direction of the placement pipe 221 smaller than the length of the cylindrical portion 231.
After flowing in from the gap between the water blocking end 2321 and the placing pipe 221, the condensed water directly flows into the water collecting cup 21 from the water inlet through hole 223. The width of the water inlet through hole 223 is smaller than the length of the cylinder 231, so that the opening range of the water inlet through hole 223 is small, the water in the water collecting cup 21 is not easy to pour out from the water inlet through hole 223, and the difficulty of backflow of condensed water into the connecting pipe body 1 is increased.
Further, the cover 222 includes a cover 2221 and a fastening portion 2222;
the cover 2221 is a hollow shell with a top closed and a bottom not closed, the cover 2221 is connected with the placing pipe 221, and the water inlet through hole 223 is arranged in the connection part of the cover 2221 and the placing pipe 221;
the fastening portion 2222 is connected to the outer edge sidewall of the covering portion 2221, the fastening portion 2222 is annular, and a plurality of fastening holes 22221 are provided on the fastening portion 2222.
The cover 2221 is configured to provide a place for placing and installing the backflow preventing assembly 24, so as to facilitate the configuration of the backflow preventing assembly 24. The fastening portion 2222 is provided with a plurality of fastening holes 22221 to facilitate the mounting of the water collecting cup 21 on the cover 222 or to facilitate the removal of the water collecting cup 21.
Further, a plurality of protrusions 111 are disposed on the outer sidewall of the fastening portion 2222.
The protrusion 111 on the fastening portion 2222 has an anti-slip effect, and the water collecting cup 21 can be easily assembled or disassembled by holding the fastening portion 2222 with one hand and rotating the water collecting cup 21 with the other hand.
Still further, the backflow preventing assembly includes a water inlet cylinder 241, a water blocking member 242 and a supporter 243;
the top of the water inlet cylinder 241 is provided with a water diversion through hole 2411, the bottom of the water inlet cylinder 241 is not closed, and the water inlet cylinder 241 is a hollow columnar body; the water inlet cylinder 241 is disposed in the inner cavity of the cover 2221 and connected to the cover 2221, and the water diversion through hole 2411 is aligned with the water inlet through hole 223;
the water deflector 242 includes a slide table part 2421 and a support part 2422; the sliding table part 2421 is in an inverted truncated cone shape, and the outer diameter of the top of the sliding table part 2421 is smaller than the inner diameter of the water inlet cylinder 241; the supporting part 2422 is arranged at the top of the sliding table part 2421 and consists of two mutually perpendicular and staggered plates, and the maximum width of the supporting part 2422 is smaller than the inner diameter of the water inlet cylinder 241 but larger than the outer diameter of the sliding table part 2421;
the water baffle 242 is arranged in the inner cavity of the water inlet cylinder 241;
the supporting body 243 is disposed in the inner cavity of the water collecting cup 21 and connected to the cover 2221;
the support 243 is a hollow shell with a top not closed, a water permeable through hole 2431 is provided at the bottom of the support 243, and the radius of the water permeable through hole 2431 is smaller than the maximum width of the support 2422.
After the condensed water flowing in through the water inlet through hole 223 flows through the water inlet through hole 223, the condensed water enters the water inlet cylinder 241 through the water diversion through hole 2411, and the condensed water flows downwards along the gap between the sliding table part 2421 and the inner cavity of the water inlet cylinder 241 because the sliding table part 2421 is not directly attached to the inner cavity of the water inlet cylinder 241 but has a certain gap, and then flows to the water permeable through hole 2431 to be collected and stored in the water collecting cup 21. The downward flow speed of the condensed water along the water inlet cylinder 241 is faster and faster because the gap between the slide table part 2421 and the inner cavity of the water inlet cylinder 241 is bigger and bigger as seen from the top down. Even if the ventilator pipe turns over, the water in the water collecting cup 21 is not easy to flow back, because the condensed water collected in the water collecting cup 21 can only flow out through the water permeable through hole 2431, and after pouring out, the condensed water can only flow out through the gap between the sliding table part 2421 and the inner cavity of the water inlet cylinder 241, and finally can enter the water diversion through hole 2411. The aperture of the water permeable through hole 2431 is not very large, so that a large amount of condensed water can be prevented from protruding out, and in addition, since the gap between the sliding table part 2421 and the inner cavity of the water inlet cylinder 241 is very small, the backflow of the condensed water can be delayed, and finally, the probability that the condensed water can flow backwards to the connecting pipe body 1 is very small through the interaction between the water blocking pipe 23 and the placing pipe 221. The support part 2422 is used to prevent the slide part 2421 from falling into the water penetration through hole 2431 and the water diversion through hole 2411, to prevent the water penetration through hole 223 from being blocked, and to prevent the slide part 2421 from falling directly into the water collection cup 21.
Further, a plurality of guide pins 2423 are provided on the bottom of the table section 2421, and the guide pins 2423 extend vertically downward.
When the sliding table part 2421 slides vertically, the guide pins 2423 can be advanced into the water permeable through holes 2431, i.e. can slide along the water permeable through holes 2431, preventing the sliding table part from greatly deviating and swinging when sliding down.
Still further, a limiting chamber 2424 is provided at the lower end of the slide table part 2421; a convex column 2425 is arranged at the top of the limit cavity 2424;
the water collection cup 21 is internally provided with a support column 211, and the top of the support column 211 is flush with the bottom of the supporting body 243.
When the sliding table portion 2421 falls to a certain position, the supporting column 211 enters the limiting cavity 2424, and finally the supporting column 211 directly lifts up the protruding column 2425 to support the sliding table portion 2421, so that the sliding table portion 2421 cannot be directly sunk into the water permeable through hole 2431, and the water permeable through hole 2431 is prevented from being blocked.
Further, a plurality of buckles 212 are provided at the outer edge side wall of the upper end of the water collecting cup 21.
The plurality of buckles 212 on the water collection cup 21 are matched and clamped with the buckle holes 22221, so that the water collection cup 21 can be conveniently taken down and assembled.
Further, a spiral protrusion 111 is provided on the outer peripheral side wall of the rotary pipe 11.
Through holding the rotation pipe 11, can make the water collecting device 2 wind the axis of rotation pipe 11 carries out three hundred sixty degrees rotations, can adjust the position of water collecting device 2 according to patient's position like this for water collecting device 2 is located all the time the minimum of rotation pipe 11 is located, in order to the collection of comdenstion water. The spiral protrusion 111 can facilitate stable gripping of the rotary pipe 11.
Further, the connecting pipe body 1 further comprises a transition pipe 3, an air outlet channel 4 and an air channel connecting body 5;
the transition pipe 3 is connected to one end of the rotating pipe 11, the air outlet channel 4 is connected to the transition pipe 3, and the air channel connector 5 is connected to the air outlet channel 4.
