Being provided with every the upper end of plug and hold needle handle, the lower end of transparent threeway is provided with extension tube, and extension tube is provided with one-hand clip, extension tube
Left end be provided with changeover valve, the left side of changeover valve is provided with breeches joint, and the left end of breeches joint is provided with valve of feeling at ease, valve of feeling at ease
Lower end be provided with medicine outlet, the upper end of medicine outlet is provided with liquid medicine catheter, and the both sides of liquid medicine catheter are provided with baffle plate, baffle plate
Both sides be provided with fixing inner shell, the outside of fixing inner shell is provided with protection shell, and the upper end of baffle plate is provided with exocoel.
A diameter of 0.5mm-1mm of described conduit.
It is provided with spring at described fixing inner shell.
A diameter of 2mm-3.5mm of described medicine outlet.
A diameter of 0.5mm-1.5mm of described liquid medicine catheter.
A diameter of 1mm-2mm of described extension tube.
Beneficial effects of the present invention: the present invention uses the joint of brand-new design, feeding opening is in closed state, it is to avoid antibacterial
Infecting, the present invention carries out tube sealing after transfusion completes automatically, it is not necessary to regularly tube sealing, and cost-effective, the valve of the present invention is unidirectional
Valve, it is to avoid blood refluxes or spills；Total, the present invention has the advantage that simple in construction, safety are high, easy to use.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of venous detaining needle of the present invention.
Fig. 2 is the partial enlarged drawing of a kind of venous detaining needle of the present invention
In figure: 1, draw point 2, conduit 3, transparent threeway 4, hold needle handle 5, intercept plug 6, extension tube 7, one-hand clip 8, switching
