Description
Technical field
The invention belongs to the field of medical instrument technology, and in particular to a kind of buttferfly-type reverse flow resistant indwelling needle.
Background technique
Pain caused by the use of remaining needle can be reduced patient due to venipuncture repeatedly and to the fear having an injection, is convenient for
Clinical application, anxious, critical patient rescue medication, mitigates the workload of nurse, reduces patient pain, thus venous detaining needle exists
Wide clinical application.The building block of core includes the conduit/casing and stainless steel that can be retained in endovascular softness
Guiding puncture needle core, when use, puncture into conduit and needle core intravascular together, after conduit fully enters blood vessel, withdraw out needle
Core, only by soft catheter retaining in the blood vessels to carry out infusion treatment, traditional remaining needle is when in use, it may appear that blood
The phenomenon that reflux, brings inconvenience to patient, in consideration of it, it is necessary to make improvement to traditional remaining needle.
Summary of the invention
To solve the deficiencies in the prior art, the purpose of the present invention is to provide a kind of easy to operate, when use can safely, can
That leans on is fixed on patient on hand, can effectively prevent the buttferfly-type reverse flow resistant indwelling needle of blood backflow.
In order to achieve the above objectives, the present invention adopts the following technical scheme that:
A kind of buttferfly-type reverse flow resistant indwelling needle, including helmet, catheter block, draw point seat, reflux plug, steel needle and conduit, steel needle setting

It is provided with silica gel sealing plug, draw point seat is set to the rear end of helmet, and reflux plug is set to the rear end of draw point seat.
Preferably, the bottom end of forgoing conduit is fixed on inside catheter block by rivet.
More preferably, aforementioned silica gel sealing plug is fixed on the Internal back end of catheter block, silicon by silica gel sealing plug attachment base
Glue sealing-plug can prevent liquid medicine flow, and access can be formed by puncturing silica gel sealing plug in infusion.
It is highly preferred that the front end of aforementioned draw point seat is provided with draw point seat insertion end, draw point seat insertion end is plugged in sheath
Internal back end, to fix draw point seat, to place steel needle.
It is further preferred that the front end of aforementioned reflux plug is provided with reflux plug insertion end, reflux plug insertion end is plugged in steel
The Internal back end of needle stand, with fixed reflux plug, reflux plug exhaust is not drained.
Specifically, forgoing conduit seat includes ontology and the fin for being set to outer body, and ontology is set to the inside of helmet
Rear end, fin are located on the outside of the rear end of helmet.
Preferably, the both ends of aforementioned fin are provided with aperture.
The invention has the beneficial effects that: buttferfly-type reverse flow resistant indwelling needle of the invention it is easy to operate, use Shi Kean
Entirely, reliably it is fixed on patient on hand, silica gel sealing plug and catheter block are combined, it can be effectively prevent blood backflow,
Silica gel sealing plug is punctured when infusion can form access.
