As shown in Figure 1, a kind of novel antireflux catheter, including urinary catheter 1, air bag 2, valve mechanism 3 and tracheae 4.Wherein,
Air bag 2 is arranged in one end of urinary catheter 1, and the inside of the urinary catheter 1 is equipped with control urine at the air bag 2 only can be to external
The valve mechanism 3 unidirectionally flowed out.One end of tracheae 4 is connected with the air bag 2, and the other end with charge valve for being connected.The gas
Pipe 4 fits close to the top half of the air bag 2 and the outside wall surface of the urinary catheter 1.It can be to air bag by charge valve and tracheae 4
Urinary catheter 1 can be fixed in human body by 2 inflations, air bag 2 after expanding, so that urinary catheter 1 accepts urine.The other end of the urinary catheter 1 point
For urethral catheterization chamber and chamber is rinsed, the urethral catheterization chamber is connected with urinal 5, is connected with flusher 6 on the flushing chamber.Urinal 5 is used for
Store the urine flowed out from urinary catheter 1.Because containing floccule or sediment in the urine of bed patient mostly, urine can be blocked in this way
Pipe 1, flusher 6 by flushing chamber and thereon can carry out irregular flushing to urinary catheter 1, keep urinary catheter unobstructed.The punching
Cleaning device 6 can be 10-20 milliliters of syringe, disposably be rinsed to urinary catheter 1.Flusher 6 is also possible to infusion apparatus,
Continual rinsing is carried out to urinary catheter 1.When selecting syringe as flusher 6, injection port can be connected through a screw thread with chamber is rinsed.
When selecting infusion apparatus as flusher 6, perfusion tube can also be connected through a screw thread with chamber is rinsed.
Specifically, as shown in Fig. 2, the valve mechanism 3 includes circular ring shape annulus 31 and at least one sheet leaflet 32.It should
The outside wall surface of circular ring shape annulus 31 is clamped on the inner wall of the urinary catheter 1, and the circular ring shape annulus 31 and the urinary catheter 1 are coaxial
Setting.Leaflet 32 is articulated on the inner wall of the annulus 31, and the leaflet 32 can in the urinary catheter 1 to extracorporeal flow
Urine flowing out and rotate and outer extend to except the annulus 31, that is to say, that when urine by urinary catheter 1 to when external outflow,
The urine of flowing can push leaflet 32 open, so that one end of leaflet 32 is to extending except annulus 31, at this point, valve mechanism 3 is in opening
State, urine can pass through urinary catheter 1 and flow to urinal；And work as urine reverse flow, from when flowing to internal in vitro, leaflet 32 is anti-
Stream urine then goes back to the state being originally closed with annulus 31 under pushing, so that reflux urine can not flow into vivo.
It is further preferred that as shown in Figures 2 and 3, the inside of the annulus 31 is in regular hexagonal prism shape structure.The leaflet
32 be three；One end in each leaflet 32 in just opposite both ends is triangle end 321, and the other end is arc end 322.Three
The triangle end 321 of leaflet 32 is preferably identical equilateral triangle.
Arc end 322 in each leaflet 32 is articulated in phase in the 31 inside regular hexagonal prism shape structure of annulus by pivot
Between two adjacent inner walls, and the structure between adjacent two inner wall is the arcwall face 311 to fit with arc end 322.
Three 32 intermediate cam shape ends 321 of leaflet are arranged in " people " font, and the edge at adjacent triangle end 321 is mutual
It is adjacent to.These three leaflets 32 are in closed state and being capable of the rotation and overhanging to the urine flowing flowed out in vitro in the urinary catheter 1
Except to the annulus 31.That is when urine passes through urinary catheter 1 to when external outflow, the urine of flowing can push three leaflets open
32 (as shown in Figure 3), so that one end of each leaflet 32 is to extending except annulus 31, at this point, valve mechanism 3 is in opened condition,
Urine can pass through urinary catheter 1 and flow to urinal；And work as urine reverse flow, from when flowing to internal in vitro, three leaflets 32 are anti-
Stream urine then goes back to original closed state under pushing, so that reflux urine can not flow into vivo.
In view of the particularity of pivot structure, it is possible that rotational angle is excessive, so that valve when leaflet 32 is opened
The excessive valve mechanism 3 of 32 opening angle of leaf is unable to normally closed.Therefore, as shown in figure 4, arcwall face 311 along axial in contraction-like,
After valve mechanism 3 is installed to the inside of the urinary catheter 1, the big opening end of the arcwall face 311 is towards the air bag 2.To make
Obtaining arcwall face 311 can be used as the confined planes of the maximum opening angle of leaflet 32.Still further preferably, the pass of three leaflets 32
Closing angle is 34 degree, and maximum open angle is 87 degree.
In order to ensure, three leaflets 32 seal enough in closure, it is ensured that the urine of reflux can not thoroughly flow back in vivo, into
With improvement, the edge at triangle end 321 is provided with sealing strip 33 to one step in each leaflet 32, so, three leaflets
When 32 closure, the edge at adjacent triangle end 321 is in abutting state, is also mutually adjacent between sealing strip 33, does not urinate to reflux
Liquid stays any gap.
In the present embodiment, it is further preferred that as shown in Figures 2 and 3, being offered in the outside wall surface of the annulus 31 more
A opening card slot 312.These opening card slots 312 are uniformly distributed along the axially extending of annulus 31, and in the circumferential direction of the annulus 31,
Moreover, these opening card slots 312 are not in breakthrough status.The opening of each opening card slot 312 is located in the annulus 31 for institute
State the side stretched out outside leaflet 32.
The clamp 11 being engaged by clamping with the opening card slot 312 is offered on the inner wall of the urinary catheter 1.By valve mechanism
3 are installed to inside urinary catheter 1 and are, annulus 31 are pushed into from urinary catheter 1 close to one end of air bag 2, the opening direction for the card slot 312 that is open
Clamp 11 pushes annulus 31 to go deep into urinary catheter 1, until opening card slot 312 and 11 clamping of clamp, to just complete valve
The assembly of film mechanism 3 and urinary catheter 1.
Above-mentioned novel antireflux catheter, on the basis of ordinary urethral catheter, in 1 inside of urinary catheter close to 2 installation at air bag
One can be to the valve mechanism 3 of external one-way flow urine, so that urine may only flow to urinary catheter from bladder, urine is passed through
Valve mechanism 3 flows in urinal from urinary catheter, if urinal height is higher than bladder height, valve mechanism is automatically closed, and prevents from urinating
Liquid reflux, reduces the risk of retrograde infection.
It is above that certain exemplary embodiments of the utility model are only described by way of explanation, undoubtedly, for
Those skilled in the art can be with a variety of different without departing from the spirit and scope of the utility model
Mode is modified described embodiment.Therefore, above-mentioned attached drawing and description are regarded as illustrative in nature, and should not be construed as
Limitation to the utility model claims protection scope.
