Specific embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are illustrated it will be appreciated that preferred reality described herein
Apply example to be merely to illustrate and explain the present invention, be not intended to limit the present invention.
Embodiment 1
As shown in figure 1, a kind of concealed syringe of the adjustable syringe needle of injection depth, including syringe 8 and hiding syringe needle 6, inject
Pipe 8 is built-in with pressure pipe 10, and the inner face of pressure pipe 10 is fixed with rubber extruded 9, and the two ends of syringe 8 are fixed with fixed station 12 He
Fixing shell 5, fixing shell 5 is fixed on the side of fixed station 12, and the top of fixing shell 5 is connected with adjustable enclosing cover 3, adjustable outer
Fixing by keeper 4 between lid 3 and fixing shell 5, the other end of adjustable enclosing cover 3 is fixed with hiding inner cap 1, hiding inner cap 1
Connected by spring 2 and adjustable enclosing cover 3 between, adjustable enclosing cover 3 is internally provided with pressure head 7, the other end of pressure head 7 is connected with hiding
Syringe needle 6, the end face center position of hiding inner cap 1 is left for hiding the through hole 11 that syringe needle 6 stretches.
Hiding inner cap 1 and adjustable enclosing cover 3 are threaded connection.The surface of hiding inner cap 1, the both sides of through hole 11 are provided with photograph
Bright lamp 13.Pass through spring 2 fixing between pressure head 7 and hiding inner cap 1.Fixing shell 5 is passed through bolt or buckle or is threadedly secured in
On fixed station 12；In medicament injection process, illuminating lamp 13 can be opened, increase intensity of illumination, assist a physician and injected.
Operation principle：
