Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described, embodiment does not form restriction of the present utility model:
This utility model improves based on 200610108072.3.
In Fig. 1, conduit 1 easily drops out, and dispenser inconvenience, and spraying time is long, and effect is bad.
In conjunction with Fig. 3, embodiment 2; Continuous Brachial Plexus Block puncturing needle special, the conduit 1 that comprises guide needle 4 and guide needle outside, it is characterized in that, described conduit 1 is transparent tube, and described conduit 1 outside comprises the film that can be filled with liquid, and described film is soft and can be close to conduit outside also separable, the film that described film is projection near the part of the syringe needle 7 of guide needle, it presses close to the wall of conduit 1 gradually away from syringe needle 7, this film comprises inner space, comprises an injection port.The technique effect of the essence that the technical scheme at this place plays is can be from outside injection port to inner injectable drug, and medicine can be propped up film, thereby causes part projection, and then forms projection and human body skin texture tissue and cooperatively interact, and material can not be dropped out.
When use, in the time that conduit and pin send toward skin texture the inside, film is soft and is close to conduit, can not cause resistance.
The film end of described projection is porose.The technique effect of the essence that the technical scheme at this place plays is to carry out slow release, and the medicine of injection can constantly carry out slow release in hole.
In conjunction with Fig. 4, embodiment 3, described conduit 1 comprises undergauge projection 6 inwardly in the outlet near syringe needle 7, and described undergauge projection 6 is towards the outlet wall thickness attenuation gradually of conduit 1.The technique effect of the essence that the technical scheme at this place plays is that projection can be adjusted the flow velocity of medicine, and the scope that adopts the inner wall shape of arc to lead medicine is distributed is larger.The syringe needle at this place is the shape of a side point.
