Description
Technical field
The utility model belongs to medical equipment technical field, and in particular to a kind of venous detaining needle.
Background technique
Venous detaining needle is widely used in clinical transfusion, is made of soft outer tube and needle core and needle stand, will when puncture
Outer tube and needle core are pierced into blood vessel jointly, are then left to remain in blood vessels soft outer tube, needle core are extracted out, by being retained in blood
Outer tube in pipe is patient's continued administration, mitigates patient's injury of vein, protects blood vessel, avoids repeatedly to puncture and bring to patient
Pain, while also mitigating the workload of medical staff.But since to be fixed on the time on patient skin longer for remaining needle,
The needle stand and calparine cap of general remaining needle use cylindrical structure, are easy to cause constriction to patient, and since patient activity makes
Do not allow to be fixed easily at the position of calparine cap, therefore, it is necessary to a kind of venous detaining needle be designed, when remaining needle can not only be avoided long
Between indwelling give patient's bring constriction in the blood vessels, and needle stand and breeches joint can be preferably fixed, especially to children
It is particularly suitable, it is also able to maintain needle stand while patient activity and the position of calparine cap is fixed.
Utility model content
