Below in conjunction with drawings and Examples scheme of the present utility model done and explain in further detail and illustrate.
Detailed description of the invention
Defer to technique scheme, see Fig. 1, syringe with stopper of the present utility model, comprise syringe, described syringe comprises needle tubing 4, is provided with and along the push rod 2 of needle tubing 4 inwall movement, described needle tubing 4 sidewall can be provided with graduation mark in described needle tubing 4, described syringe is provided with the stopping means 3 for limiting push rod 2 displacement, described stopping means 3 is provided with fixture 1.
Described stopping means 3 is for keeping the negative pressure state of syringe inside; Described fixture 1, for being fixed on by device of the present utility model with it patient, being convenient to patient and being worn.
Particularly, described stopping means 3 comprises the fixing head 301 detachably installed with needle tubing 4 port edge; Described fixing head 301 is detachably vertically provided with length-adjustable support bar; The end of described support bar is movably installed with ring for fixing 305, and described fixed trap is contained in the end edge of push rod 2.
Described fixing head 301, for ensureing that support bar is vertically arranged between push rod 2 end and needle tubing 4 end edge, makes support bar play the effect of support, thus the displacement of restriction push rod 2; Described support bar adjustable length, when for meeting different vacuum magnitude in needle tubing 4, the situation that push rod 2 is different from the spacing of needle tubing 4 end, thus make device of the present utility model have stronger adaptability; Described ring for fixing 305 is sleeved on the end edge of push rod 2, for increasing the stability of support bar.
