Description
Technical field
This utility model relates to medical instruments field, especially relates to a kind of multifunctional medical threeway extension tube.
Background technology
At hospital intensive care unit, conditions of patients is critical, in order to infuse and monitor, the often multiple catheter of indwelling, simultaneously in order to monitor conditions of patients change, need to frequently extract blood and check, to monitor conditions of patients change, assess therapeutic effect.
In order to avoid complication such as site of puncture hematoma, arteriovenous inflammation and infection that repeated localised puncture causes, reducing patient suffering, medical worker often extracts blood from arterio-venous catheter and checks.
But take a blood sample in arterio-venous catheter, liquid in arterio-venous catheter can affect inspection result, the blood extracted out returns and may result in infection generation in the patient, therefore blood sampling again after the liquid needing to abandon in conduit and a certain amount of diluted blood, generally 5-8ml blood, to avoid affecting testing result because of hemodilution and infecting.
Therefore, repeatedly can cause certain iatrogenic 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, separating for several times three way cock every day, adds the chance of systemic contamination.
Based on this, this utility model provides a kind of multifunctional medical threeway extension tube to solve above-mentioned technical problem.
