Abstract
The invention belongs to the technical field of medical apparatus and instruments, and particularly relates to an anti-falling central venous catheter without suture. The anti-falling central venous catheter without suture includes an internal tube and a soft tube; one end of the soft tube is connected to a connection joint; the internal tube is provided with an air bag; and the air bag communicates with the outside environment through an air bag tube. The advantages of the invention are that: the central venous catheter is used for thoracocentesis and abdominocentesis; the air bag is inflated through an air bag connection opening, the air bag swells, the air bag is attached to the inner wall of a puncture surface, the friction force between the internal tube and the puncture surface increases, and then the internal tube cannot fall out of a thoracic cavity and an abdominal cavity; and the central venous catheter can avoid suture and suture removing, is reasonable in a whole design, and is simple in structure.
Description
Technical field
The invention belongs to technical field of medical instruments, especially relate to a kind of exempt to stitch anti-slip central vein and lead
Pipe.
Background technology
Central venous catheter is a kind of common medical apparatus and instruments, and patient is infused by it by puncture technique.
At present, existing central venous catheter needs to sew up, and clinical part doctor is in order to alleviate patient suffering, also
The saving time, do not sew up, add the risk of shedding.
In order to improve prior art, people have carried out long-term exploration, it is proposed that various solutions
Certainly scheme.Such as, Chinese patent literature disclose a kind of central venous catheter [application number:
CN201520393653.0], including built-in pipe, holder, connection flexible pipe, clamp, union joint；Built-in pipe,
Holder, connection flexible pipe, union joint are sequentially connected with, and clamp is arranged on connection flexible pipe, by opening on clamp
If slit optionally tube sealing；Described central venous catheter is characterised by: described connection blown tubular becomes
Two sections, the first end of first paragraph is connected with holder, and the second end of first paragraph forms attachment means；Second segment
First end formed attachment means, the second end of second segment is connected with union joint, and clamp is arranged on second segment；
The attachment means of first paragraph is releasably secured together with the attachment means of second segment.
Although such scheme to some extent solves the deficiencies in the prior art, however it is necessary that stitching, do not stitch
During conjunction, pipeline easily comes off, and global design is the most reasonable.
Summary of the invention
It is an object of the invention to for the problems referred to above, it is provided that a kind of reasonable in design, simple in construction, it is not necessary to seam
What conjunction can either prevent that pipeline from slipping exempts to stitch anti-slip central venous catheter.
For reaching above-mentioned purpose, present invention employs following technical proposal: originally exempt to stitch anti-slip central vein
Conduit, it is characterised in that include built-in pipe and flexible pipe, pass through holder between described built-in pipe and flexible pipe
Being connected, the other end of described flexible pipe is provided with jointing, and described built-in pipe is provided with air bag, described
Air bag be connected with the external world by airsac tube.Being inflated in air bag by balloon interface, air bag is softened,
Air bag is affixed on vein inwall, and frictional force between built-in pipe and vein inwall becomes big, built-in pipe be not easy from
Deviating from vein, can exempt stitching, take out stitches, global design is reasonable, simple in construction.
Exempting to stitch in anti-slip central venous catheter above-mentioned, described air bag includes around built-in pipe circumference
Equally distributed first Nang Bao, the second Nang Bao and the 3rd Nang Bao, described the first Nang Bao, the second Nang Bao and
It is connected by junctional membrane between three capsule bags.
Above-mentioned exempt to stitch on the junctional membrane described in anti-slip central venous catheter have passage.
Exempt to stitch the airsac tube described in anti-slip central venous catheter and against built-in pipe outer wall above-mentioned and prolong
Stretch, and the port of export of airsac tube is all connected with balloon interface.
Exempt to stitch the airsac tube described in anti-slip central venous catheter and be embedded in built-in pipe above-mentioned or set
Putting on the outer surface of built-in pipe, described airsac tube is uniformly distributed relative to built-in pipe circumference.
Above-mentioned exempt to stitch the first Nang Bao described in anti-slip central venous catheter, the second Nang Bao, the 3rd
Closing space is surrounded between Nang Bao and junctional membrane.
Compared with prior art, the advantage originally exempting to stitch anti-slip central venous catheter is, passes through air bag
Interface is inflated in air bag, and air bag is softened, and air bag is affixed on vein inwall, built-in pipe and vein inwall it
Between frictional force become big, built-in pipe is not easy from vein abjection, can exempt stitching, take out stitches, global design
Rationally, simple in construction.
Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below will be to enforcement
In example or description of the prior art, the required accompanying drawing used is briefly described, it should be apparent that, describe below
In accompanying drawing be only some embodiments of the present invention, for those of ordinary skill in the art, do not paying
On the premise of going out creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation that the present invention provides.
Fig. 2 is the sectional view that the present invention provides.
In figure, built-in pipe 1, flexible pipe 2, holder 3, jointing 4, air bag 5, airsac tube 6, first
Capsule bag the 7, second capsule bag the 8, the 3rd capsule bag 9, junctional membrane 10.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clearly
Chu, be fully described by, it is clear that described embodiment be only a part of embodiment of the present invention rather than
Whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creation
The every other embodiment obtained under property work premise, broadly falls into the scope of protection of the invention.
As shown in Figure 1-2, originally exempt to stitch anti-slip central venous catheter and include built-in pipe 1 and flexible pipe 2, built-in
Being connected by holder 3 between pipe 1 and flexible pipe 2, the other end of flexible pipe 2 is provided with jointing 4, built-in
Pipe 1 is provided with air bag 5, and air bag 5 is connected with the external world by airsac tube 6.By balloon interface to air bag 5
Middle inflation, air bag 5 is softened, and air bag 5 is affixed on vein inwall, between built-in pipe 1 and vein inwall
