Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

By figure 1 to 6 give, including controlling axial syringe 1, 1 right side coaxial disassembly of syringe is connected with the needle handle 2 of opening towards the left, set up the spout 3 of falling L shape on the 1 right side of syringe outer fringe face, set up the draw-in groove 4 with 3 intercommunications of spout on the 1 right side of syringe outer fringe face, be equipped with on 2 inside walls of needle handle and can be at draw-in groove 4 and 3 gliding sliders 5 of spout, 2 right-hand members of needle handle coaxial be equipped with wash needle 6, articulated on the needle handle 2 have the transparent plate 7 of left right direction.

In order to facilitate the fixation, the right side of the injector 1 is coaxially provided with a spring 8 positioned at the left side of the needle handle 2.

In order to facilitate screwing the needle handle 2, a plurality of anti-slip strips 9 which are uniformly distributed along the circumferential direction of the needle handle 2 are arranged on the outer edge surface of the needle handle.

In order to facilitate limiting the transparent plate 7, the front end of the needle handle 2 is provided with a limiting plate 10, the upper side and the lower side of the front end of the limiting plate 10 are respectively provided with a hemispherical limiting groove 11, the front side of the transparent plate 7 is provided with a circular groove 12 with a front axial direction and a rear opening, the circular groove 12 is internally provided with a limiting column 13 which can be inserted into the limiting groove 11 in a coaxial sliding manner, and the front end of the limiting column 13 is connected with the front side wall of the circular groove 12 through a pressure spring 14.

In order to facilitate the clear observation of medical staff, the upper end of the transparent plate 7 is provided with a magnifier 15.

In order to accommodate the washing needle 6, a left-right placing groove 16 is formed at the lower end of the transparent plate 7, and the washing needle 6 can be inserted into the placing groove 16.

The utility model discloses when using, at first set up the state that syringe 1 and needle handle 2 separate as initial condition, use syringe 1 to absorb the flush fluid of allotment, insert syringe 1 right-hand member in needle handle 2, make slider 5 slide to the left in spout 3, extrude spring 8 left simultaneously, slider 5 and spout 3 left side wall contact after sliding a distance, medical personnel anticlockwise rotate needle handle 2 this moment, needle handle 2 slides down in spout 3, because spring 8 right elasticity slider 5 slides to the draw-in groove 4 after sliding a distance, realize the spacing to needle handle 2, prevent to cause needle handle 2 to drop because of pushing injection pressure is too big;

at the moment, the transparent plate 7 is pulled leftwards, the transparent plate 7 swings leftwards on the needle handle 2, the pulling force is larger than the elastic force of the pressure spring 14, the limiting column 13 slides out of the limiting groove 11 on the upper side, the transparent plate 7 continues to rotate, the rotation is stopped when the transparent plate 7 rotates to 90 degrees with the needle handle 2, at the moment, the limiting column 13 is inserted into the limiting groove 11 on the lower side again due to the backward elastic force of the pressure spring 14, the fixed limiting of the transparent plate 7 is realized, and the transparent plate 7 is prevented from swinging in the washing process;

medical personnel will wash needle 6 and insert and begin to carry out the lacrimal passage in the patient's lacrimal punctum and wash, medical personnel's accessible magnifying glass 15 detailed observation patient condition this moment, when flush fluid refluence appears, transparent plate 7 can block the washing liquid of splash and patient's secretion, prevent that the splash from leading to the fact the occupation to medical personnel face and expose, after washing the completion, pull transparent plate 7 right, transparent plate 7 swings right to initial position, it is located standing groove 16 to wash needle 6 this moment, the realization is to accomodating of washing needle 6, prevent stabbing patient and medical personnel, medical personnel press needle handle 2 backward, slider 5 slides in 3 spout, clockwise rotation needle handle 2, because spring 8 right elasticity is with needle handle 2 from 1 bullet down of syringe, to needle handle 2 and syringe 1 carry out disinfection treatment can.
