Outer extremely interior opening.
In a further preferred embodiment, the check valve sheet is disk compatible with the internal diameter of negative pressure cylinder, the circle
Wherein one end of piece is rotatably connected in the inner wall of the negative pressure cylinder, and the inner wall of the negative pressure cylinder is opposite with the disk
The position of the other end is equipped with retention bead.
In a further preferred embodiment, the cover is dome brim structure made of silica gel material.
In a further preferred embodiment, the cover is the structure made of silica gel material with two side flaps.
The utility model has the beneficial effects that
1, by the repacking to existing syringe, easy Crater nipple appliance is obtained, material easily obtains, structure letter
Single, the patient lighter for symptom, as long as the head end of existing syringe is removed, will push away without in addition buying special rectifier
Bar instead fills the Crater nipple appliance that the utility model can be obtained.
2, a kind of Crater nipple appliance of the utility model, has the advantages that of simple structure and low cost；Increase finger ring
With convex ribs, salient point or undulated structure, one hand can also operate correction；The front end of negative pressure cylinder and scale made of transparent material
Setting, realize operation when can also observe and adjust on one side；Check valve sheet makes when carrying out negative pressure traction that manpower can be certain
It is move freely in time；Cover is that more fitting human skin realization negative pressure, dome brim structure or two sides are made in silica gel material
Tab construction can increase the fitting area with human skin.
The utility model is described in further detail with reference to the accompanying drawings and embodiments；But a kind of cream of the utility model
Head invagination rectifier is not limited to the embodiment.
Detailed description of the invention
