The specific embodiment
For further setting forth this utility model is to reach technological means and the effect that predetermined goal of the invention is taked, below in conjunction with accompanying drawing and preferred embodiment, to according to its specific embodiment of safety blood taking needle cylinder device, structure, feature and the effect thereof that the utility model proposes, describe in detail as after.
See also Fig. 1, Fig. 2 and shown in Figure 3, be the outside drawing and the exploded view of this utility model one preferred embodiment.This utility model comprises:
One syringe 10, be hollow tube-shape, form a fixing head 11 on the one end, form a storage tank 12 on this fixing head 11, this storage tank 12 is a rectangle, and a trough rim outwards forms an arc section 13, forms a projection 14 again on this fixing head 11, and this projection 14 is the arc sections 13 with respect to this storage tank 12.In addition, this syringe 10 is provided with a barrier plate 15 with respect to the other end opening dual-side of fixing head 11, and extend to form a partition 16 respectively relatively in the in addition both sides of this end, and this barrier plate 15 can be fastened on this partition 16 inboards, with the end opening in addition of sealing syringe 10;
One top cover 20 rotatably is set on this syringe 10, and forms an opening 21, and what form on these top cover 20 medial surface that a ring-type has a height gradient supports the section of pulling 22;
One needle stand 30, be oval column, its two end portions is provided with an inside/outside needle point body 31/32, this inside/outside needle point body 31/32 is also made the ㄣ font and is arranged on needle stand 30, should outer needle point body 32 be by this opening 21, and be exposed at this syringe 10 outsides, concave on the outer diametric plane of these needle stand 30 1 ends and form a necking segment 33, and be fastened on the arc section 13 of this storage tank 12 with the minor face of this necking segment 33, needle stand 30 long edge lengths are greater than the minor face groove width (referring to arc section 13 places especially) of storage tank 12 on the syringe 10, but long limit groove width less than storage tank 12, the long edge lengths of the necking segment 33 of this needle stand 30 are then less than the minor face groove width (referring to arc section 13 places especially) of storage tank 12 on the syringe 10, therefore, when needle stand 30 long limits are parallel with storage tank 12 minor faces, its necking segment 33 snaps in the groove edge of arc section 13, and needle stand 30 then is fixed on the fixing head 11 of syringe 10;
One pinhead sleeve 40 is set on this outer needle point body 32 by top cover 20 outsides.
Please consult Fig. 4 and shown in Figure 5 again, be the profile of this utility model one preferred embodiment.When the nursing staff uses this utility model to draw blood, two minor faces of these needle stand 30 necking segment 33 are the arc section 13 of this storage tank 12 of engaging and growing relatively on the limit of this storage tank 12, therefore, the nursing staff thrusts outer needle point body 32 by after in the blood vessel of bleeder, again interior needle point body 31 is protruded in the collecting pipe and collect blood, when treating that blood collecting is extremely a certain amount of, then this collecting pipe can be pulled up, and should detach by bleeder by outer needle point body 32.
Please cooperate in regular turn and consult Fig. 6, Fig. 7 and shown in Figure 8, be the action profile of this utility model one preferred embodiment.When nursing staff's blood drawing finishes, behind these top cover 20 rotations 270 degree, make this support the section of pulling 22 and move to eminence by lower with the relative place of pulling that supports of the projection 14 of this fixing head 11, after making this fixing head 11 bear a downward external force effect, when treating that this top cover 20 continues to rotate again, the lower that should support the section of pulling 22 will move on this projection 14 once more, and this projection 14 is slightly risen, the fluctuating up and down of this fixing head can be become flexible the fastening state of 12 of the necking segment 33 of this needle stand 30 and this storage tanks.The same time, necking segment 33 minor faces of this needle stand 30 are moved on the minor face by the arc section 13 of this storage tank 12, because the long edge lengths of this storage tank 12 is long than the bond length of this needle stand 30, therefore, after this needle stand 30 rotations one angle, the minor face of this necking segment 33 is positioned on the minor face of this storage tank 12, make this necking segment 33 leave this storage tank 12, add the dipping and heaving of this fixing head 11, make this necking segment 33 can break away from the groove edge of this storage tank 11 fully, therefore, this needle stand 30 is not subjected to the support of this storage tank 11 and drops in this syringe 10.
In addition, the barrier plate 15 of this syringe 10 can be fastened on by depressing on this partition 16, and needle stand 30 can be blocked in this syringe 10, therefore, when medical personnel changed over to this needle stand 30 to this syringe 10, this needle stand 30 was to be positioned at this syringe 10, and outside unlikely this syringe 10 that drops out.
Because this utility model is to utilize top cover 20 to drive this needle stand 30 to rotate, and then this needle stand 30 fallen into to this syringe 10, make and can not expose outside this syringe 10 by outer needle point body 32, and because this utility model need not the nursing staff use hands that this pinhead sleeve is set on this outer needle point body 32, therefore, reduce the nursing staff and be subjected to the risk that syringe needle stabs.
The above, it only is preferred embodiment of the present utility model, be not that this utility model is done any pro forma restriction, though this utility model discloses as above with preferred embodiment, yet be not in order to limit this utility model, any those skilled in the art, in the scope that does not break away from technical solutions of the utility model, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be not break away from the technical solutions of the utility model content, foundation technical spirit of the present utility model is to above any simple modification that embodiment did, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
