Description
Technical field
This utility model relates to a kind of injection needle apparatus, refers to a kind of safe retrieving assembly of needle set especially.
Background technology
Therapeutic medical injection needle apparatus, such as interior fistula aerofoil profile pin (A.V. Fistula Set), scalp acupuncture (Scalp Vein Set) and general transfusion dripping entry needle device, its structure consist predominantly of entry needle, for this entry needle sheathed upper shield and be connected in series the tube for transfusion of this entry needle.In use, need first to take off upper shield, upper shield is returned cover after using by pin to be injected again, causes danger to avoid the syringe needle of entry needle outside exposed.But because the trepanning of upper shield is minimum, add medical treatment on-the-spot urgent and by situations such as other contacts personnel interference, collisions, healthcare givers often easy when upper shield returns lid accidentally by needle sting, and unexpected cause infection, therefore needle set still also exists the problem in much safety on using.
For the problems referred to above, there are front case such as US5030212 " Puncture guard for needle administration set ", US5330438 " Protective sheath for butterfly needles and IV infusion set and sheath assembly " at present, US5562637 " Needle protector sheath " and TW325410 " inside contracts concealed aerofoil profile multifunctional safe infusion dropper ".The main tube for transfusion sheathed recovery external member in advance being all needle set rear, after pin to be injected uses, first grasp tube for transfusion respectively with both hands and reclaim external member, again by tube for transfusion this recovery external member pull backward relatively, entry needle can be taken in this recovery external member, and do not need upper shield to return cover, avoid upper shield to return the danger of cover, promote the safety that needle set uses.
But above-mentioned front case still has not enough place to have much room for improvement, and main cause is:
1. need first to grasp tube for transfusion respectively with both hands and reclaim external member, and cannot singlehandedly use, comparatively inconvenience in use.
2. an aspect due to needle set fin not easily smoothly income reclaim in external member, also needle set rear is preset in owing to reclaiming external member on the other hand, therefore user needs length longer for tube for transfusion pull, so that entry needle easily produces whipping when pull tube for transfusion, and have the possibility of stabbing hand, be still comparatively not enough with safety.
