Specific embodiment
The utility model is described further with reference to the accompanying drawing.
As shown in the picture, the utility model includes the hollow puncture needle 1 of hard, and indwelling needle catheter 2 and catheter block 3 its feature exist
In further including being arranged on catheter block 3 and the hoop limit sleeve 4 close to 1 one end of puncture needle, the hoop limit sleeve 4 include half
Circular first arc panel 5, semicircular second arc panel 6, four root cutting pin shafts 7 and two fixed plates 8 form, and described first
Arc panel 5 and the opposite along its length both ends of the second arc panel 6 are equipped with the first hole 10, and the fixed plate 8 is equipped with two
A second hole 11, every root cutting pin shaft 7 is across the second hole 11 of fixed plate 8 and the first arc panel 5 and the second arc panel 6
The first hole 10 top of first arc panel 5 and the second arc panel 6 is detachably connected, first arc panel 5 and second
The lower part of arc panel 6 is hinged by a shaft, to realize the detachable of the hoop limit sleeve 4 and the catheter block 3
Connection, the bottom of the hoop limit sleeve 4 are pasted with a rubber slab 18, and rubber slab 18 and the angle of 4 bottom surface of hoop limit sleeve are
30 °, the end of the close needle point of the puncture needle 1 is uniformly provided with multiple hemispheric recessed portions 9, institute along the circumferencial direction of needle body
The middle part for stating catheter block 3 is additionally provided with hand-held part 12, the hand-held part 12 be oppositely arranged on one group of 3 two sides of catheter block to
The cylindric rubber bar of outer lug.
The length of the rubber slab 18 is the 1/2-2/3 of 3 length of catheter block, facilitates the operation punctured.
The diameter of the recessed portion 9 is 0.4-0.6mm, and diameter crosses the pain sense of discomfort that conference causes patient.
The length of the cylindric rubber bar is 2-4cm, and nurse is facilitated to carry out hand-held grasping.
Working method and principle: semicircular first arc panel 5, semicircular second arc panel 6 are set in institute first
