Second outer tube 22 the conical inner side wall of first outer tube 12 and tapered exterior sidewall of the second outer tube 22 during being spirally connected move closer to
Until fitting.First inner tube 11 and the second inner tube 21 realize the connection of dialysis inner tube 1 and external take over 2 during being spirally connected, this
It, can when the two is contradicted and is bonded outside by the way that the tapered exterior sidewall of the conical inner side wall and the second outer tube 22 of the first outer tube 12 is arranged
The stroke that is spirally connected for playing limit the first inner tube 11 and the second inner tube 21, the position when being spirally connected due to the first inner tube 11 and the second inner tube 21
In the stroke that is spirally connected can not be observed in the first outer tube 12 and the second outer tube 22, pass through the conical inner side wall and second of the first outer tube 12
The tapered exterior sidewall of outer tube 22 is arranged, and the first inner tube 11 of limit and the second inner tube 21 can be played under abutting state in the two
Be spirally connected stroke, and correct position is screw-coupled to be advantageously implemented the first inner tube 11 and the second inner tube 21.And pass through the first inner tube
11 are spirally connected with the second inner tube 21, and the conical inner side wall of the first outer tube 12 is abutted with the tapered exterior sidewall of the second outer tube 22, is being dialysed
The interface of inner tube 1 and external take over 2 realizes dual sealing structure, is conducive to the connection effect for improving interface and close
Seal effect.
Dialysis inner tube 1 includes liquid pipe 14 and to be sheathed on the regulation pipe 15 changed outside liquid pipe 14 for conveying changing for dialyzate,
The length for changing liquid pipe 14 is more than the length of regulation pipe 15, changes liquid pipe 14 and partly extends 15 end of regulation pipe after regulation pipe 15
Portion, regulation pipe 15 include the bending tube 151 positioned at end and the fixing pipe 152 positioned at middle part, and two are provided in fixing pipe 152
A terylene for secured adjusted pipe 15 covers 153；Dialysis inner tube 1 by 151 part of bending tube be placed into it is intraperitoneal after pass through fixation
Terylene set 153 on pipe 152 fixes dialysis inner tube 1.
It is both provided on the lateral wall of 151 opposite sides of bending tube for the notch 1511 for 151 bending of bending tube, is lacked
Mouthfuls 1511 are provided with multiple, and are arranged along the length direction of bending tube 151, in the pipe thickness direction of regulation pipe 15
Portion is provided with perforation 1512, and there are two 1512 settings of perforation, and is located at the opposite sides of regulation pipe 15, in perforation 1512
Interspersed to be provided with regulation and control rope 1513, the interface of regulation pipe 15 towards dialysis inner tube 1 is provided with for operating regulation and control rope 1513
Revolving part 154, revolving part 154, which is socketed on, to be changed outside liquid pipe 14, and positioned at regulation pipe 15 end, regulation and control rope 1513 one end with
The one end of bending tube 151 far from fixing pipe 152 is fixedly connected, the other end of regulation and control rope 1513 after the regulation pipe 15 with revolving part
154 connections；Wound clockwise is in the outside of revolving part 154 after wherein one regulation and control 1513 perforated 1512 of rope pass through regulation pipe 15
Wall, and its end is fixedly connected with revolving part 154；Another regulation and control 1513 perforated 1512 of rope pass through the inverse time after regulation pipe 15
Needle is wound in the lateral wall of revolving part 154, and its end is fixedly connected with revolving part 154；Revolving part 154 is in rotation process
In, a regulation and control rope 1513 is withdrawn around revolving part 154, and another regulation and control rope 1513 is released around revolving part 154, reaches control bending
The flexion of pipe 151.Will dialysis inner tube 1 be placed in it is intraperitoneal after, can pass through rotate revolving part 154 control two regulation and control rope
1513 folding and unfolding, to enable 15 flexion of regulation pipe, can make in regulation pipe 15 change liquid pipe 14 also being capable of the side of adjustment
To the program can realize adjustment dialysis inner tube 1 in intraperitoneal position, you can realization will be changed liquid pipe 14 and be moved to abdominal cavity most
Bottom can also avoid the patient feels from being conducive to abnormal to be conducive to improve dialytic efficiency by mobile inner tube 1 of dialysing
Improve the placement comfort of dialysis inner tube 1.
Two terylene set 153 is located at 152 both ends of fixing pipe, fixing pipe 152 at hard curve bend structure setting.
The fixing pipe 152 of hard enables to the relative position between two terylene sets 153 that can fix, while fixing pipe 152 is at arc
Shape bend pipe structure is arranged so that the terylene set 153 of both sides can be arranged with an opposite angle intersected, when one of terylene
When set 153 will deviate from tunnel, another terylene covers 153 due to being moved towards different by the chucking power and channel of muscle, thus
So that can check and balance between two terylene sets 153, it is more difficult to deviate from tunnel, be conducive to the fixed effect for improving fixing pipe 152
Fruit；And the both sides tunnel opening on stomach wall is enabled to be arranged downward so that peritoneal dialysis solution under the influence of air pressure can
Enough more smooth passes through dialysis inner tube 1, reduces the generation of obstruction.
The lateral wall of terylene set 153, which is surrounded with, contradicts item 1531, contradicts the outside that item 1531 is surrounded on terylene set 153
On wall, and closely abutted between adjacent conflict item 1531.When the inner tube 1 that will dialyse is positioned over intraperitoneal, need deep layer
Terylene set 153 is fixed on rectus aabdominis, and the terylene set 153 of shallow-layer is fixed in hypodermic tunnel of 2 centimetres away from skin, passes through muscle groups
It knits clamping terylene and covers 153 to fix the relative position of dialysis inner tube 1, the annular of multilayer, which contradicts item 1531, to be clamped admittedly in muscle
Periodically, increase the frictional force between muscle and terylene set 153 so that muscle more fixedly can cover 153 by de-clamping terylene, make
Not changing for relative position can be kept by obtaining terylene set 153, so as to ensure the stability of dialysis 1 relative position of inner tube, together
When item 1531 contradicted so that can form the clamp area more compacted between musculature and Dacron pipe due to the annular of multilayer
Domain, so that the thing other than tunnel face is difficult to enter in tunnel, so that the safety higher of Dacron pipe.
The above is only the preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-described embodiment,
All technical solutions belonged under thinking of the present invention all belong to the scope of protection of the present invention.It should be pointed out that for the art
For those of ordinary skill, several improvements and modifications without departing from the principles of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
