It is located at through in the slideway opened up on the tube wall of needle tubing, the slideway is L-shaped, including the axial direction opened up from cork to needle stand direction
Section and the circumferential sections for opening up and being connected with axial direction part close to cork position.
Preferably, detent mechanism, detent mechanism bag are provided between the short tube that any two of the needle guard is mutually arranged
Include the circular orientation projection that circumferentially arranged cross section semicircular in shape is distinguished on the outer tube wall at the both ends of the smaller short tube of caliber
And the cross section circumferentially opened up respectively on the inner tubal wall at the both ends of the larger short tube of caliber is in corresponding semicircular annular
Locating slot.
Preferably, the needle guard includes three sections of short tubes.
Preferably, the needle guard is located at outmost short tube the end symmetric of cork is being provided with two sliding blocks, pin
Two corresponding slideways are offered on the tube wall of pipe.
Preferably, the needle stand is threadedly attached in the end of needle tubing, and the Handheld Division of butterfly-type is connected with needle stand.
Preferably, the needle guard be located at outmost short tube close to cork one end tube chamber in be provided with pipe close.
Beneficial effect
The utility model is driven by setting telescopic needle guard in the tube chamber of needle tubing during puncture needle is extracted
Needle guard synchronous extension, puncture needle is received into needle guard, prevents the blood of subsidiary sufferer on its tip or needle body to medical personnel
Cause cross-infection, the short tube in needle guard is provided with detent mechanism, is not easy to bounce back after needle guard stretching, extension, will not cause puncture needle
Syringe needle is secondary to be spilt, and further ensures the health of medical personnel.As a result of telescopic needle guard, relative to prior art
In be arranged at the needle guard of the same length of puncture needle, volume of the present utility model greatly reduces, and it is more flexible to apply pin position mode, most
The beneficial effect for having played venous detaining needle of big degree.
