Background technique
Venous detaining needle is a kind of medical instrument for infusion, the remaining needle of existing venous detaining needle
Indwelling needle tubing generallys use metal material and is made, due to needle tubing tube wall can not light transmission, when medical staff is to the vein blood vessel of patient
When being punctured, need whether the blood back cavity being located in catheter block by observation blood back occur to judge indwelling needle tubing
It is pierced into the vein blood vessel of patient.
In some special circumstances, the vein blood back speed of patient can be slack-off, such as some blocked up meetings of patient's subcutaneous fat
Cause vein blood back slow, sometimes when patient used the drug of control blood pressure or in big bleeding etc. in special circumstances, vein
Blood pressure also can be relatively low slow so as to cause vein blood back.And the syringe needle of general indwelling needle tubing apart from blood back cavity farther out, it is sometimes too low
Blood pressure is difficult to squeezing into blood into blood back cavity, and the blood in Venous Blood pipe flows to needed for blood back cavity from the syringe needle of indwelling needle tubing
Time far more than medical staff be pierced into Venous Blood pipe operating time, this will lead to medical staff be difficult to precisely judge be
It is no to be pierced into the vein blood vessel of patient, it is punctured repeatedly to generate, since duct wall is very thin, puncturing repeatedly can cause
There is fold in conduit, generates thrombus, causes mechanical phlebitis, meaningless pain is brought to patient, while also reducing medical care people
The working efficiency of member.
