Abstract
The utility model discloses a special circulating line of ECMO convenient to blood sampling, include: the circulating line with set up on the pipeline and the blood sampling end of perpendicular to pipeline, the blood sampling end is cylindricly, and the skin is hollow rigid plastic layer, and the inner chamber communicates with each other with the circulating line, is provided with the sealing rubber post in the rigid plastic layer, the center of sealing rubber post be provided with with the communicating space of inner chamber, the blood sampling syringe needle can be inserted in the space to be in encapsulated situation when insertion needle not. The utility model discloses structure novel structure, the simple operation has not only compensatied the operating difficulties of taking a blood sample on the both ends pipeline of QUADROX PLS membrane lung, has leaded to a blood or a flush fluid spun difficult problem easily to aseptic technique reduces the emergence of infecting.
Description
Technical field
This utility model belongs to medical instruments field, particularly to a kind of ECMO Special circulation pipeline being easy to blood sampling.
Background technology
ECMO (extracorporeal membrane oxygenation, ECMO) blood circulation mainly by membrane lung,
Centrifugal pump head and pipeline composition.Membrane lung is linked together by pipeline with centrifugal pump head, and by venous incubation with body vessel even
Connect, the venous blood of patient pump by centrifugation is drained to external, through the gas exchange of artificial lung (oxygenator), make venous oxygen be combined into
Arterial blood, then it is fed back to internal, provide stable circulation volume for cardiorespiratory failure patient.
The merit of oxygenator is judged clinically by the color of blood after perusal membrane lung oxygenate, the aberration etc. of arteriovenous pipeline
Can, having most judge to be worth is to gather oxygenator two ends blood to carry out blood gas analysis, observes.QUADROX PLS membrane lung
Two ends pipeline is provided with arteriovenous vim and vigour measurement port, and operation uses syringe to gather blood through external tapping, uses sterile injection afterwards
By water or 0.9% normal saline pulsed, blood in pipeline is washed down.ECMO maintains blood flow 2～4L/min when running substantially,
All there are when leaving and taking blood specimen and injection flushing liquor bigger impulsive force, operation difficulty to control, cause blood or flushing liquor ejection or nothing
Bacterium operation quality difficulty controls the infection caused.
Take a blood sample mouth so that the collection blood sample of safety is this area on the pipeline at the two ends how designing QUADROX PLS membrane lung
Unsolved technical barrier.
Utility model content
The purpose of this utility model is the defect for prior art, it is provided that a kind of ECMO Special circulation pipe being easy to blood sampling
Road.
To achieve these goals, this utility model is by the following technical solutions: a kind of ECMO being easy to take a blood sample is special to follow
Endless tube road, including: circulating line and the blood sampling termination being arranged on pipeline and being perpendicular to pipeline；Described blood sampling termination is cylindrical,
Outer layer is the hard plastic layer of hollow, and inner chamber communicates with circulating line, is provided with caulking gum post in hard plastic layer, described close
The space being provided centrally with communicating with inner chamber of envelope rubber column, described space is inserted into blood collection needles, and when being not inserted into syringe needle
It is in sealing state.
It is provided with, outside described blood sampling termination, the block being connected with termination.
In described blood sampling termination a diameter of the 1.5～2.5cm of caulking gum post.
Described caulking gum post uses medical grade silicon rubber to make.
Described circulating line one end is the oxygenator end connecting oxygenator, and the other end is to connect venous cannulation or arterial cannulation
Intubating end, described blood sampling termination is positioned at oxygenator end 5～10cm.
In use, the oxygenator end of circulating line is connected oxygenator, intubate end and connect venous cannulation or arterial cannulation, open
Dynamic ECMO, in ECMO running, as required every the set time, opens the block of blood sampling port, from sealing
The gap of rubber column is inserted blood collection needles, artery and vein end is carried out blood sampling, extracts syringe needle after blood sampling, and close the lid
Cap.
This utility model architecture is novel, and simple operation not only compensate for the two ends pipeline of QUADROX PLS membrane lung
Upper blood sampling operating difficulties, be easily caused blood or flushing liquor ejection a difficult problem, and sterile working reduce infect generation.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of this utility model ECMO Special circulation pipeline.
Detailed description of the invention
With specific embodiment, the application is described further below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of this utility model ECMO Special circulation pipeline, including: circulating line 1 be arranged on
On pipeline and be perpendicular to the blood sampling termination 2 of pipeline.
Blood sampling termination is cylindrical, and outer layer is the hard plastic layer 3 of hollow, and inner chamber communicates with circulating line, hard plastic layer
Inside it is provided with caulking gum post 4.Blood sampling termination in caulking gum post a diameter of 1.5～2.5cm, use medical grade silicon rubber make.
The space 5 being provided centrally with communicating with inner chamber of caulking gum post, space is inserted into blood collection needles, and when being not inserted into syringe needle
It is in sealing state.Blood sampling is provided with, outside termination, the block 6 being connected with termination.
Circulating line one end is the oxygenator end 7 connecting oxygenator, and the other end is to connect intubating of venous cannulation or arterial cannulation
End 8, described blood sampling termination is positioned at oxygenator end 5～10cm.
During use, the oxygenator end of circulating line is connected oxygenator, intubate end and connect venous cannulation or arterial cannulation, open
Dynamic ECMO, in ECMO running, as required every the set time, opens the block of blood sampling port, from sealing
The gap of rubber column is inserted blood collection needles, artery and vein end is carried out blood sampling, extracts syringe needle after blood sampling, and close the lid
Cap.
The above, be only preferred embodiment of the present utility model, and this utility model not does any type of limit
System.Every above example is made according to technology of the present utility model and method essence any simple modification, equivalent variations with
Modify, all still fall within the range of technology of the present utility model and method scheme.
