Description
Technical field
A kind of the invention belongs to medical instruments field, more particularly to venous indwelling path hemostix.
Background technology
Clinically, it is an important diagnosis and state of an illness basis for estimation, especially serious symptom patient's blood specimen to be tested
Patient, is accurately to grasp patient's change of illness state, adjusts remedy measures in good time, often needs timing blood sampling to check.It is clinical at present to adopt more
With blood specimen being obtained to the method for patient's systemic vein puncture blood collecting again, for critically ill patient, there is venous indwelling path patient
It is not good enough with peripheral circulation, do not possess the patient of periphery tip blood sampling condition often using existing venous indwelling path, using many
Individual blood collection needle.Concrete grammar is：Using three syringes.After carrying out disinfection to venous indwelling pathway junctions, with first
Syringe extracts the liquid more than twice venous indwelling path volume out, discards（Therefore section liquid may the heparin containing tube sealing
Deng other drugs, and the risk of germ contamination, venous indwelling path should not be refilled）；Second syringe is connected, 5- is extracted
10ml liquid is placed on one side（In order that a small amount of catheter lock solution remained in venous indwelling path is extracted as far as possible, Yi Mianying
Ring the assay of blood specimen）；The 3rd syringe is connected, the blood preparation required for extracting, in injection blood taking tube；Again again
Second syringe is connected, the 5-10ml liquid just extracted out is injected in venous indwelling path.Transfusion device continuation is connected finally
Infusion treatment.Sometimes for operation is simplified, first syringe is extracted into 5-10ml liquid and is discarded, then it is direct with a syringe
Blood specimen is extracted, iatrogenic loss so can be caused to blood in patient body, patient's prognosis is affected.
There are some researches prove, the blood specimen gathered by venous indwelling path when method is proper and periphery tip blood specimen inspection
As a result it is consistent, therefore venous indwelling path blood sample collection can be passed through.And the measure taken at present has the following disadvantages：It is many
The secondary joint for changing venous indwelling path and syringe, pollutes risk increase, increases whole device during whole operation
The probability of open pollution.Such as reduce by a step, it will cause the iatrogenic loss of blood in patient body, lose ethics and
Patient's curative effect.Process is complicated, time-consuming longer, affects other work of nurse.Process is complicated, consumes more medical supplies.It is based on
More than, it is necessary to a kind of hemostix for being specifically designed for the blood sampling of venous indwelling path is invented, operation simplification, science, safety is made.
The content of the invention
