Specific implementation mode
In conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, invention is further explained, a kind of reverse headgear instrument, including
Reverse headgear maintainer, the reverse headgear maintainer include infusion apparatus joint 1, and the infusion apparatus joint 1 is equipped with top
Hold closed conduit 2,2 a diameter of 0.5mm of conduit.The conduit 2 is made of metal material, the conduit 2 packet
It includes the straight tube 21 being connected with infusion apparatus joint 1 and is folded up the branch pipe 22 with straight tube 21 at angle, the straight tube 21 length
Degree is 12mm, and 22 length of branch pipe is 10mm, and the angle between the straight tube 21 and branch pipe 22 is 130 °.By branch pipe 22 and directly
The structure that pipe is turned up realizes that intraocular can be adjusted perfusion in single reverse headgear maintainer one-handed performance, without other auxiliary
Help instrument, simple operation effective.22 front end of branch pipe is pouring head 23, set on the side wall of the pouring head 23 there are two
Symmetrically arranged fill orifice 24, forms through-hole 25 between the symmetrically arranged fill orifice 24, and the through-hole 25 is a diameter of
