Description
Technical field
The invention belongs to medical instruments field, more particularly to a kind of cellular-type venous detaining needle.
Background technology
Venous detaining needle is also known as venous catheter needle, and the building block of core includes that endovascular soft lead can be retained in
Pipe/sleeve pipe, and the guiding puncture nook closing member of stainless steel, conduit and nook closing member are punctured into together during use it is intravascular, when conduit is complete
After portion's intravasation, nook closing member is withdrawn out, only the catheter retaining of softness is particularly suitable for use in the blood vessels so as to carry out infusion treatment
The patient of intermittent, continuity or daily infusion.The major advantage of venous detaining needle is that of avoiding patient at one
Multiple puncture is undergone in the course for the treatment of, reduces the pain that patient punctures repeatedly, also mitigates the financial burden of patient；Venous indwelling
Pin needs to carry out tube sealing washing pipe when in use, and the purpose of tube sealing washing pipe is that the excitant decoction of residual is poured into blood flow, avoids next time
Flexible pipe head end blood clotting during connection transfusion, results in blockage；Before infusing again, the decoction remained in conduit need to be poured blood vessel
（It is commonly called as washing pipe）, avoid because stimulate local vascular and caused by chemically phlebitis, reduce the incompatibility between medicine.At present
The venous detaining needle of in the market has the defects of one very big, and finish gentle to drug microparticles does not have entirely exactly in dosing and washing pipe
There is iris action, in order to overcome this defect, we add a separation filter on product, separate filter in dosing
Effectively drug microparticles and bubble can be separated with during washing pipe, existing for the venous detaining needle for effectively solving in the market
Problem.
The content of the invention
The main technical problem to be solved in the present invention is to provide a kind of cellular-type venous detaining needle, the cellular-type venous indwelling
Pin includes：Remaining needle pin overcoat, the soft pin of remaining needle, remaining needle draw point, flexible pipe, positive pressure connector, connection infusion apparatus joint, the first shield
Cap, separate filter, the second helmet.
The present invention is that the technical scheme used is：
A kind of cellular-type venous detaining needle, including：The soft pin 2 of remaining needle pin overcoat 1, remaining needle, remaining needle draw point 3, flexible pipe 4, just
Crimp head 5, connection infusion apparatus joint 6, the first helmet 7, separation filter 8, the second helmet 9；Remaining needle pin overcoat 1 is enclosed on indwelling
On the soft pin 2 of pin, remaining needle draw point 3 is placed in the soft pin 2 of remaining needle and can moved up and down, and the soft pin 2 of remaining needle and the left end of flexible pipe 4 connect
Connect, the right-hand member and positive pressure connector 5 of flexible pipe 4 connect, and a branch of positive pressure connector 5 and connection infusion apparatus joint 6 connect, and connection is defeated
The first helmet 7 is cased with liquid device joint 6, another branch of positive pressure connector 5 and separation filter 8 connect, and separate filter 8
Right side is provided with washing pipe liquid import, and the second helmet 9 is cased with washing pipe liquid import.
The present invention further technical scheme be：
Remaining needle draw point 3 is made up of handle and draw point, and pit is provided with handle.
Described positive pressure connector, separate filter, the first helmet, the second helmet and be made up of medical polyurethane material.
The beneficial effects of the invention are as follows：A kind of cellular-type venous detaining needle is provided, the product structure is simple, operation side
Just it is, cheap, a separation filter is especially added on product, separating filter can be effective in dosing and washing pipe
The drug microparticles and bubble to dosing separate, the venous detaining needle for effectively solving the problems, such as in the market is present；Production
Product are particularly suitable for use in the patient of intermittent, continuity or daily infusion, and avoiding patient will be through in a course for the treatment of
The pain repeatedly punctured is gone through, also mitigates the financial burden of patient.
Brief description of the drawings
Structure chart for the present invention as shown in Figure 1.
Embodiment
With reference to specific embodiment, the present invention is described in further detail.
In use, nurse need to only prepare the medicine of injection, the first helmet 7 is pulled out, by connection infusion apparatus joint 6 and is needed
The drug delivery conduit connection of injection, decoction are run to the soft pin 2 of remaining needle, remaining needle draw point 3 by flexible pipe 4, should now arranged
Except pin inner air tube, i.e. available hand pinches the handle of remaining needle draw point 3 by the soft pin 2 of remaining needle, indwelling after being carried out disinfection to human body
Pin draw point 3 penetrates the blood vessel of patient, and remaining needle draw point 3 then exited into human body, and the decoction of normal injection is along the soft pin 2 of remaining needle
Into human body；After a shot terminates, decoction import is cut off, covers the first helmet 7；The second helmet 9 is pulled out, will disposably be rinsed
Device and its connection, after the disposable flusher full of physiological saline or heparin diluent is extruded, physiological saline therein or liver
Plain dilution filters off particle or gas that may be present by separating filter 8, and tube sealing is carried out into cellular-type venous detaining needle,
After tube sealing terminates, disposable flusher is laid down, covers the second helmet 9；During injection next time, the be cased with washing pipe liquid import is pulled out
Two helmets 9, by disposable flusher and its connection, the disposable flusher full of physiological saline or heparin diluent is extruded
Afterwards, physiological saline or heparin diluent therein filter off particle or gas that may be present by separating filter 8, into separation
Formula venous detaining needle carries out washing pipe, after washing pipe terminates, pulls out washing pipe liquid, puts the second helmet 9；The first helmet 7 is pulled out, will be connected
Infusion apparatus joint 6 carries out second after being connected with the drug delivery conduit that need to be injected and infused.
Certainly, the present invention also has other embodiments, any skill done under the spiritual background without departing from the present invention
The improvement of art, principle and technique, is within the scope of the present invention.
