Description
Technical field
The present invention relates to medical instruments field, especially relate to a kind of multifunctional medical threeway extension tube.
Background technology
At hospital intensive care unit, conditions of patients is critical, and in order to infuse and monitor, the often multiple catheter of indwelling, simultaneously in order to monitor conditions of patients change, needs the frequent blood that extracts to check, to monitor conditions of patients change, and assessment therapeutic effect.
In order to avoid site of puncture hematoma that repeated localised puncture causes, arteriovenous are scorching and the complication such as infection, reduce patient suffering, medical worker often extracts blood inspection from arterio-venous catheter.
But take a blood sample in arterio-venous catheter, liquid in arterio-venous catheter can affect check result, the blood extracted out returns in patient body may cause infecting and occurs, therefore blood sampling is again needed to abandon after liquid in conduit and a certain amount of diluted blood, be generally 5-8ml blood, to avoid affecting testing result because of hemodilution and infecting.
Therefore, repeatedly can cause certain iatrogenicly to lose blood from arterio-venous catheter blood sampling, especially for child, the blood relatively abandoned is more.Meanwhile, the patient of intensive care unit(ICU) needs to inject multi-medicament every day, and separating for several times three way cock adds the chance of systemic contamination.
Based on this, the invention provides a kind of multifunctional medical threeway extension tube to solve above-mentioned technical problem.
Summary of the invention
The object of the present invention is to provide a kind of multifunctional medical threeway extension tube, with to solve in prior art repeatedly can cause certain iatrogenicly to lose blood from arterio-venous catheter blood sampling, and the patient of intensive care unit(ICU) needs to inject multi-medicament every day, separating for several times three way cock, easily produces the technical problem polluted.
