Detailed description of the invention
As shown in Figure 1 and Figure 2; a kind of safety injector; comprise cylindrical shell 3 and entry needle 1; push rod 2 is provided with in cylindrical shell 3; cylindrical shell 3 is being provided with syringe needle stiff end 31; entry needle 1 comprises needle stand and needle tubing, and entry needle 1 outside is provided with pin cap, may be used for protecting the entry needle 1 after being sterilized sterilization can not be contaminated bottom pin cap.Described safety injector also comprises needle protecting arrangement; needle protecting arrangement comprises connector 4, fixed part 5 and protective sleeve 6; the connector 4 of hollow comprises front end 41 and the rear end 42 of integral structure, and front end 41 is fixed with entry needle 1, and rear end 42 is fixed with syringe needle stiff end 31.Fix fixed part 5 outside rear end 42, fixed part 5 is flexibly connected protective sleeve 6, and protective sleeve 6 can be rotated around fixed part 5 to entry needle 1 direction or cylindrical shell 3 direction.The cavity 62 of storage entry needle 1 is provided with in protective sleeve 6, with, prevent the stop part 63 that entry needle 1 is fled from from cavity 62, when protective sleeve 6 rotates to entry needle 1 direction, entry needle 1 can be received into (as Fig. 3) inside cavity 62.
Fixed part 5 with being flexibly connected of protective sleeve 6 can be:
A: as Fig. 1, protective sleeve 6 is provided with through hole 61, and fixed part 5 fixes one end of crosspin 52, and the other end of crosspin 52 is through through hole 61, and protective sleeve 6 can with crosspin 52 for axle rotates.
B: as Fig. 3; protective sleeve 6 is provided with swivelling chute 66, and fixed part 5 fixes the two ends of rotating shaft 55, is provided with the space that swivelling chute 66 passes through between fixed part 5 and rotating shaft 55; rotating shaft 55 can enter swivelling chute 66 from the opening part of swivelling chute 66, and protective sleeve 6 can with rotating shaft 55 for axle rotates.
C: as Fig. 4; fixed part 5 and protective sleeve 6 are provided with connecting portion 8, two ends connecting portion 5 and the protective sleeve 6 respectively of connecting portion 8, and the centre of connecting portion 8 is turnover mechanism 81; be provided with elastic mechanism 82 immediately below turnover mechanism 81, the two ends of elastic mechanism 82 are separately fixed at the two ends of elastic mechanism 82.When protective sleeve 6 rotates, turnover mechanism 81 does fold return motion.When protective sleeve 6 rotates to an angle, elastic mechanism 82 is stretched to maximum, and now, no matter to entry needle 1 or cylindrical shell 3 fine rotation little by little, the strength of elastic mechanism 82 reset makes protective sleeve 6 to this direction accelerated motion to protective sleeve 6.Such setting, open or closed needle protecting arrangement time, only protective sleeve 6 need be rotated half way, protective sleeve 6 can reach assigned address automatically, saves the muscle power of operator.At present, be all generally complete above-mentioned work by nurse, and nurse is generally women, the amount of labour is large again at ordinary times, and the design is very applicable to them.
As Fig. 1, the end of fixed part 5 is provided with the retainer ring 51 of opening, and retainer ring 51 is looped around the rear end 42 of connector 4, completes fixing.
Stop part 63 is at least one needle tubing safety door hook, and after a procedure, protective sleeve 6 is pushed into entry needle 1 place, needle tubing safety door hook is buckled on needle tubing the syringe in the present embodiment.
Best, connector 4 described above, fixed part 5 are integrated with protective sleeve 6, more firmly, also more easily produce.Material can be plastics, and cost is low.
Its operation principle is:
Medical personnel, in use the present embodiment process, first by outer for protective sleeve 6 turnover, and then complete injection process; After injection process completes, protective sleeve 6 is pushed on entry needle 1 by medical personnel from the side, and whole entry needle 1 part will directly cover by protective sleeve 6, and the stop part 63 in protective sleeve 6 is stuck on needle tubing, prevents needle point from exposing and hurts sb.'s feelings.In the process, medical personnel do not puncture the risk of finger.
In prior art, the needle stand of entry needle is directly installed on cylindrical shell and is being provided with syringe needle stiff end, and needle stand and syringe needle stiff end are universal component, are applicable to the syringe of various model.This utility model utilizes this point exactly, and the front end of connector 4 and syringe needle stiff end are similar to, and rear end and needle stand are similar to, so connector is also universal component, is equivalent to complete twice between needle stand with syringe needle stiff end and is connected, do not affect use after adding it.
