Detailed description of the invention
The invention will be further described with embodiment below in conjunction with the accompanying drawings, and embodiments of the present invention include but not limited to
The following example.
Embodiment 1
As it is shown in figure 1, a kind of unidirectional valve cribbing drainage system, including by polylactic acid radical biological degradable shape-memory material
The support made and unidirectional valve；Described support original state by middle part be hollow cylinder 1 and be arranged at hollow cylinder two ends with
The central axial outer radial barrier rib 2 of hollow cylinder；Described unidirectional valve is positioned at hollow cylinder.
Wherein, described unidirectional valve is the portable plate 3 that one end is hinged with hollow cylinder inwall；The other end of described portable plate
It is also associated with pull rope 4.
Specifically, described portable plate is connected by bearing pin 5 with hollow cylinder inwall, and is provided with position use at hollow cylinder inwall
The barrier plate 6 rotated to side it is only capable of in restraint plate.What above-mentioned barrier plate was concrete be positioned at bearing pin side, so it can be avoided that
Portable plate rotates to opposite side, thus realizes the effect of unidirectional unlatching.
If having hydrops in patient's tube chamber, when needing to get rid of, can operate in being drained into gastral cavity by said apparatus,
First it is at gastral cavity sidewall opening, simultaneously to lumen open, subsequently device one end of the present embodiment is entered opening part and reach tube chamber
In, the other end is stayed in gastral cavity, so that tube chamber connects with gastral cavity, thus carries out drain.Specifically, the support of the present embodiment uses
Polylactic acid radical biological degradable shape-memory material, keeps such as the structure of Fig. 1 when original state；But it is implanted to people carrying out
Internal, first it is carried out thermoplastic, be then conformed into Fig. 2 structure, then cool down, the most above-mentioned dress
Putting and all can keep Fig. 2 shape and structure, being also equivalent to is a tubulose, the most just can be respectively protruding into accordingly at body two ends
Two chambers in, subsequently due to temperature raise, the support of the present embodiment will gradually be deformed into original state, and barrier rib just can
Enough stop support slip in chamber and affect drainage effect, thus successfully carry out drain；Additionally, due to being provided with unidirectional valve,
Also it is equivalent to be check valve, it is possible to realize one-way flow, it is to avoid gastric acid carries out in other chambers, it is ensured that drainage process
Safety.Additionally, the present embodiment is provided with pull rope, when needs carry out liquid medicine injection or other liquid from gastral cavity to other chambers,
Pulling traction rope can be passed through, portable plate is lifted, thus just can carry out injecting fluid from gastral cavity to other chambers.Operation ten
Divide simple.
Preferred as one, it is connected between described pull rope and portable plate and has soluble wire.By arranging soluble wire, in operation
After end, soluble wire can be absorbed molten short, the most just easily can be taken out by pull rope, and support and unidirectional valve are by gathering
Lactyl Biodegradable shape-memory material is made, so also being able to explain in vivo, eliminates taking-up
The operation of support, thus greatly reduce patient suffering.It is made up it addition, described pull rope also can be adopted of degradation material, this
Sample also is able to absorb completely, then need not further take out, thus decrease operation technique, improve efficiency.
Embodiment 2
As it is shown on figure 3, the difference of the present embodiment and embodiment 1 is, the barrier plate of the present embodiment is arranged at portable plate away from pin
One end of axle, is so equivalent to carry out barrier activity plate rotation from bottom, can achieve the function of unidirectional unlatching, so simultaneously
After this barrier plate be only a fritter, as long as can rotate to this side by barrier activity plate.
Embodiment 3
As shown in Figure 4, the present embodiment is with the difference of embodiment 1, and described pull rope is provided with portable away from one end of portable plate
Part 10.By arranging portable part, very convenient when pulling traction rope, and do not have sense of discomfort.
Embodiment 4
As it is shown in figure 5, from the difference of embodiment 1, the present embodiment is that unidirectional valve is different, the unidirectional valve of the present embodiment includes
The dividing plate 7 axially arranged along hollow cylinder, this dividing plate will be divided into two chambers in hollow cylinder；One end of described dividing plate is provided with
For controlling the first check valve that one of them chamber is opening/closing；The other end be provided with for control that another chamber is opening/closing second
Check valve.
Specifically, described first check valve and the second check valve are identical, and all include the work that one end and hollow cylinder are hinged
Moving plate 8, and be arranged on hollow cylinder inwall for restraint plate be only capable of to side rotate stopper 9.
By dividing plate, hollow cylinder is separated into two chambers, and is controlled flowing by the check valve that both direction is different
Direction, so when carrying out drain, is flowed in gastral cavity by one of them valve, when an injection is needed, then can pass through another
Individual valve is by liquid infusion to other chambers.Easy to operate, and without using pull rope to draw；The most above-mentioned
Parts are made by polylactic acid radical biological degradable shape-memory material, can degrade with oneself, it is not necessary to remove and prop up after having performed the operation
Frame, thus avoid and remove the misery brought to patient.
Embodiment 5
As shown in Figure 6, the present embodiment is with the difference of embodiment 4, and described first check valve and the second check valve are identical, and all
Including the activity template 8 that one end and dividing plate are hinged, and it is arranged on hollow cylinder inwall and is only capable of to side for restraint plate
The stopper 9 rotated.The present embodiment fixes portable plate from embodiment 4 and to arrange the position of stopper different, by arranging position
Difference, equally can reach corresponding unidirectional unlatching effect, so that the present invention can realize in several ways.
According to above-described embodiment, the present invention just can be realized well.What deserves to be explained is, before designing based on said structure
Put, for solving same technical problem, even if some made in the present invention are without substantial change or polishing, used
The essence of technical scheme still as the present invention, therefore it should also be as within the scope of the present invention.
