It is completely enclosed, be provided with stage clip between the other end and seal receptacle of pole, stage clip make lid and seal receptacle tight against；Drainage lumens go out liquid
Female thread is provided with mouthful.
Herein, encirclement is referred to and surrounded along its surrounding, but does not result in the blocking of enclave.Drainage lumens are entered
Liquid mouth is surrounded by air bag and refers to that air bag surrounds inlet along the surrounding of inlet, and the height of air bag exceedes the height of inlet,
And air bag will not block inlet.
The principle of this programme：During operation, this structure is inserted in bladder, the inlet of drainage lumens is located at low relative to air bag
Position, the urine that stream enters from inlet controls it and flows out or cut-off by enclosed switch.When urine is in outflow state, can lead to
Cross and be threadedly coupled external urinal；When urine is in cut-off state, can not external urinal.
Compared with prior art, the utility model has the advantage of：1st, the inlet of drainage lumens is surrounded by air bag, i.e. air bag
Height exceed the height of inlet, and air bag will not block inlet, and when this structure is inserted in bladder, air bag is located at
A high position, positioned at low level, the clot, stone in urine, pus, slough also readily flows to low level to inlet, then from inlet
Middle discharge, does not easily cause clot, stone, pus, and necrotic tissue accumulation is in intravesical.2nd, the outer rim of seal receptacle is circumferentially sealedly connected on
On the inwall of drainage lumens, it is ensured that the sealing of seal receptacle and drain cavity wall.3rd, runner and through hole are provided with seal receptacle, lid can
Runner and through hole are completely enclosed, the sealing of drainage lumens is capable of achieving.4th, lid is provided with pole, is provided between pole and seal receptacle
Stage clip, lid is connected on the inwall of drainage lumens, and when external force is not applied, lid is with seal receptacle tight against lid is by runner and leads to
Hole completely encloses, and realizes the sealing of drainage lumens；When lid is pulled out, lid is separated with seal receptacle, exposes runner, and urine can
Flow out.5th, be provided with female thread at the liquid outlet of drainage lumens, can be connected with externally threaded urinal, between drainage lumens and urinal
Connection is more firm.This utility model is easy to the clot in urine, stone, and pus, slough is discharged；Drainage lumens are provided with close
Sealing switch, had both been easy to drain intracavity to maintain gnotobasiss, and the discharge of urine is facilitated again；Connect more jail between drainage lumens and urinal
Gu, urinal is difficult from drain intracavity to deviate from.
Preferred version one, based on basic technology scheme, the drainage lumens are provided with bellows segment, and lid is connected to drainage lumens
In bellows segment.Bellows segment can freely extend and shorten, and be moved easily lid.
Preferred version two, based on preferred version one, because two points determine that the quantity of a face, the pole and through hole is equal
At least two, can guarantee that the overall steady rise and fall of lid.
Preferred version three, it is symmetrical along drainage lumens cross-section center between pole or between through hole based on preferred version two, make
Uniform force between multiple poles and through hole.
Preferred version four, based on preferred version three, the lid is provided with rubber layer, rubber layer near the one side of seal receptacle
Elastically deformable, can preferably be sealed.

Specific embodiment
This utility model is described in further detail below by specific embodiment：
Reference in Figure of description includes：Body 1, air bag 2, drainage lumens 3, inlet 4, seal receptacle 5, lid 6,
Pole 7, bellows segment 8, urinal 9, stage clip 10.
Embodiment is substantially as shown in Figure 1：A kind of dual-purpose sterilized catheter, including body 1, body 1 is provided with air bag 2,
Drainage lumens 3, fluid injection chamber are provided with body 1 and chamber is rinsed, there is bellows segment 8 in drainage lumens 3.
Air bag 2 is in petal shape, and the inlet 4 of drainage lumens 3 is located at the center of air bag 2, and inlet 4 is surrounded by air bag 2, feed liquor
Mouth 4 is located at low level relative to air bag 2, and air bag 2 is connected with fluid injection chamber.
As shown in Fig. 2 drainage lumens 3 are provided with enclosed switch, enclosed switch includes seal receptacle 5, lid 6 and two poles 7.
The outer rim of seal receptacle 5 is circumferentially sealedly connected on the inwall of drainage lumens 3, and runner and two through holes, two through hole are provided with seal receptacle 5
Along the centrosymmetry of the cross section of drainage lumens 3, a diameter of 2mm of runner or so.Two poles 7 are each passed through two through hole, pole 7 with it is logical
Hole is slidably connected, and the lower end of pole 7 is connected on lid 6, and the upper end of pole 7 is connected with stage clip 10, and stage clip 10 is connected to pole 7
And seal receptacle 5 between.The top surface of lid 6 is provided with rubber layer, and lid 6 is by flexible belt body and the inwall of the bellows segment 8 of drainage lumens 3
Connection, and lid 6 can completely enclose runner and through hole, stage clip 10 make lid 6 and seal receptacle 5 tight against；The liquid outlet of drainage lumens 3
Place is provided with female thread, as shown in figure 3, the joint of urinal 9 used cooperatively with it is provided with the external screw thread for matching.
In the present embodiment, during operation, first air bag 2 is placed in human bladder, after treating the fully-inserted bladder of air bag 2, is led to
Fluid injection chamber is crossed to water filling in air bag 2, makes this structure be fixed on intravesical, air bag 2 is brought into close contact with the inwall of bladder.Because feed liquor
Mouth 4 is located at low level relative to air bag 2, and the clot, stone in urine, pus, slough can sink with its gravity, flow to low level,
Then discharge from inlet 4, be not likely to produce dead angle.When not exerting a force to lid 6, because stage clip 10 can pull up pole 7, lid
6 also can pull up therewith, and the runner and through hole on seal receptacle 5 is blocked, and realize the sealing of drainage lumens 3.When lid 6 is drop-down
When, lid 6 can produce gap with seal receptacle 5, and runner can expose, and urine can flow out from runner.When lid 6 is drop-down, meeting
In advance external urinal 9, prevents urine pollution medicated clothing and environment.Threaded connection, urinal 9 are used between urinal 9 and drainage lumens 3
It is difficult to be come off from this structure.When not exerting a force to lid 6, can not external urinal 9, because urine is in itself aseptic, therefore will draw
Stream chamber 3 will not pollute drainage lumens 3 as the space of temporary transient storage of urine.
Above-described is only embodiment of the present utility model, the general knowledge here such as known concrete structure and characteristic in scheme
Excessive description is not made.It should be pointed out that for a person skilled in the art, in the premise conceived without departing from this utility model
Under, some deformations and improvement can also be made, these should also be considered as protection domain of the present utility model, and these are all without impact
