Abstract
The utility model is related to a kind of heart-lung machine fastener conversion kit, is characterised by：Including the tubular body being engaged with heart-lung machine fastener socket, the opening for being easy to inserting is formed with the tube wall axial direction of the tubular body, the length of the opening matches with tubulose body length, one end of the tubular body is provided with the positive stop lug boss being connected as a single entity with it.Advantage is：When the pipeline clinically needed to use does not match with the size of heart-lung machine fastener socket, the conversion kit of the specification can be installed additional outside pipeline insertion end, pipeline and conversion kit are then inserted into heart-lung machine fastener socket again, you can meet use requirement.This conversion kit is simple and practical, with low cost, safe and reliable, reduces the working strength of medical worker；The control of external producer can effectively be contained, patient's treatment burden is considerably reduced.
Description
Technical field
The utility model belongs to clinical treatment technique with the apparatus field, more particularly to a kind of heart-lung machine fastener conversion sleeve
Part.
Background technology
The heart-lung machine clinically used is made up of oxygenator, blood pump and auxiliary equipment, can be followed in vitro
The mechanical device of ring, the extracorporal circulatory system, the assisted respiartion of lung transplantation, acute respiration that heart-lung machine is used for openheart surgery is tended to end because of decline
Auxiliary treatment.During Clinical practice, venous blood is drawn from patient's venous system, and oxygen is closed in vitro, then through blood pump that oxygenated blood is defeated
Return the overall process of arterial system, also known as cardiopulmonary bypass.Each pump head of each heart-lung machine is provided with the fastener of various models,
To fix extracorporeal circulation pipeline.Because there are some technical problems in domestic heart-lung machine at present, therefore larger heart
Center uses the heart-lung machine of import, but the fastener of import heart-lung machine is more expensive, and producer is reluctant to provide unnecessary fastener,
Once parts breakdown or loss, purchase are got up not only expensive and needs to supply from genuine man, the cycle is long.Further, since
Extracorporeal circulation pipeline much uses British system specification in the world, and domestic extracorporeal circulation pipeline is much metric system, fastener with
Extracorporeal circulation pipeline can have error when coordinating, and then increase the working strength of medical worker, and there is potential safety hazard.
The content of the invention
The utility model for solve technical problem present in known technology provide it is a kind of it is easy to operate, simple in construction,
Clinical practice is safe and reliable and can mitigate the heart-lung machine fastener conversion kit of medical worker's working strength.
The utility model is adopted the technical scheme that to solve technical problem present in known technology：
Heart-lung machine fastener conversion kit, it is characterised in that：Including the tubular body being engaged with heart-lung machine fastener socket, institute
The opening for being formed with the tube wall axial direction of tubular body and being easy to inserting is stated, the length of the opening matches with tubulose body length, described
One end of tubular body is provided with the positive stop lug boss being connected as a single entity with it.
The utility model can also be adopted the following technical scheme that：
The wall thickness of the tubular body is equal to the difference that heart-lung machine fastener inserts internal diameter and pipeline external diameter at pipe.
The tubular body is made using PVC material.
The utility model has the advantages and positive effects of：Because the utility model uses above-mentioned technical proposal, when facing
When the pipeline needed to use on bed does not match with the size of heart-lung machine fastener socket, this turn can be installed additional outside pipeline insertion end
Set is changed, pipeline and conversion sleeve are then inserted into heart-lung machine fastener socket again, you can meet use requirement.This conversion sleeve is easy to be real
With, it is with low cost, it is safe and reliable, reduce the working strength of medical worker；The control of external producer can effectively be contained, significantly
Degree reduces patient's treatment burden.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the schematic diagram of the utility model use state.
In figure：1st, tubular body；2nd, it is open；3rd, positive stop lug boss；4th, pipeline；5th, heart-lung machine fastener；6th, conversion kit.
Embodiment
For invention, features and effects of the present utility model can be further appreciated that, following examples are hereby enumerated, and coordinate
Accompanying drawing describes in detail as follows：
Refer to Fig. 1-Fig. 2, heart-lung machine fastener conversion kit, including the tubulose being engaged with the socket of heart-lung machine fastener 5
The opening 2 for being easy to inserting, length and the tubulose body length kissing of the opening are formed with body 1, the tube wall axial direction of the tubular body
Close, one end of the tubular body is provided with the positive stop lug boss 3 being connected as a single entity with it.
In the present embodiment, the wall thickness of the tubular body be equal to heart-lung machine fastener insert internal diameter and pipeline external diameter at pipe it
Difference.
In the present embodiment, the tubular body is made using PVC material.
Operation principle of the present utility model is：
Extracorporeal circulation pipeline external diameter be generally 12.7 (12.0) mm, 9.5 (10.0) mm, 7.9 (8.0) mm, 6.4 (6.0) mm,
4.7 (5.0) mm and 3.2 (3.0) mm, when the pipeline 4 for clinically needing to use 9.5mm, without match fastener when, can be with
Install this conversion kit 6 additional and be suitable for 12.7mm fasteners, if 12.7mm fasteners are not can also install circle this conversion additional yet
External member is directly supporting with heart-lung machine；7.9mm pipelines, the no corresponding fastener in the world, install a circle or a few this conversion sleeve of circle additional for another example
Part is to be suitable for various situations.
Embodiment described in the utility model accompanying drawing is exemplary, is only used for explaining the utility model, and can not be managed
Solve as to limitation of the present utility model.
