Description
Technical field
This utility model relates to a kind of disposable syringe, is specifically related to a kind of automatic retracting type safety self-destruct disposable syringe.
Background technology
Safe re-use preventing once-used syringe is widely used in medical field, has avoided using unhygienic syringe and the viral cross infection that produces.But common disposable syringe is because the problem of structure causes certain operations person to carry out secondary use or repeatedly use; The violation operation of user produces cross infection; Reuse in order to stop artificial recovery, people are provided with self-desttruction equipment on disposable ordinary syringe.But; Though re-use preventing once-used syringe can prevent the repeated use of syringe; But syringe uses the back because entry needle exposes and makes depleted syringe in processes such as collection, transportation, processing, produce many inconvenience; Still might stab medical worker and its related personnel, cause the cross infection of virus and bacteria.Therefore, designing a kind of entry needle disposable syringe of the safety self-destruct function of retraction automatically, is the urgent needs in current market.
The utility model content
Goal of the invention: to the deficiency that exists in the prior art, the purpose of this utility model provides a kind of automatic retracting type safety self-destruct disposable syringe, to satisfy user demand.
Technical scheme: in order to realize the foregoing invention purpose, the technical scheme that this utility model adopts is following:
A kind of automatic retracting type safety self-destruct disposable syringe comprises needle tubing, syringe and injection core rod; Be provided with the needle tubing seat that links to each other with needle tubing on the top of syringe; In injection core rod, be provided with spring base, between spring base and injection core rod, be provided with spring; Between spring base and needle tubing seat, be provided with plug, described plug is fixed on the end of injection core rod; Be provided with the stopping ring on the top of spring base, be provided with the conical grab that matches and use with the stopping ring in the bottom of needle tubing seat.
Between described needle tubing seat and syringe, be provided with O type circle.
The rear end of described spring base be provided with injection core rod on the snap ring that cooperates of draw-in groove.
Between described injection core rod rear end and syringe, be provided with the lamellar safety plate.
The drift of described spring is 40 ~ 70mm.
Beneficial effect: the automatic retracting type safety self-destruct disposable syringe of this utility model, rational in infrastructure simple, can accomplish retraction and the disposable use of safety self-destruct automatically; Cross infection can not take place, because needle tubing bounces back in the cylindrical shell automatically, in using last handling process, can not stab medical worker and its related personnel yet; And product is easy to manufacture, cheap; Safe in utilization, have good practicability, can produce good economic benefits and social benefit.
Description of drawings
Fig. 1 is the structural representation of automatic retracting type safety self-destruct disposable syringe;
Fig. 2 is the enlarged drawing of the local A of Fig. 1;
Fig. 3 is a retraction back sketch map.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is further described.
As depicted in figs. 1 and 2, automatic retracting type safety self-destruct disposable syringe structure mainly comprises injection needle 1, needle tubing seat 2, plug 5, spring 6, spring base 7, syringe 11 and injection core rod 10.Needle tubing 1 is bonded in the endoporus of needle holder 2, and needle holder 2 is contained in the liquid-through hole of syringe 11 front ends, is provided with conical grab 14 in the bottom of needle tubing seat 2.On the liquid-through hole of syringe 11, be provided with groove 4, in groove 4, establish O type circle 3, be used for the gap between needle seal base 2 and the syringe 11.What injection core rod 10 can stretch back and forth is located in the syringe 11; In injection core rod 10, be provided with draw-in groove 9; Be provided with snap ring 8 on the top of spring base 7, snap ring 8 makes spring base 7 be fixed in the injection core rod 10 after snapping in draw-in groove 9, between spring base 7 and injection core rod 10, is provided with spring 6.Be provided with stopping ring 15 on the top of spring base 7, conical grab 14 can tighten locking each other with stopping ring 15.Plug 5 is located in the syringe 11, is used to separate injection and injection core rod 10, and links to each other with an end of injection core rod 10, and conical grab 14 and stopping ring 15 are located at the both sides of plug 5.Be provided with in the bottom of injection core rod 10 and press hands 13, between syringe 10 and injection core rod 11, be provided with safety plate 12, its effect is: when syringe uses, must get rid of safety plate, could shift injection core rod onto the end, make liquid medicine injection all inject human body; Prevent before completed knocked down products and syringe use misoperation and being taken place by the phenomenon of self-destruction; Whether can make user clearly discern syringe was used.
This automatic retracting type safety self-destruct disposable syringe is the 5mL syringe, and the drift of spring 6 is 40 ~ 70mm.By the color of hands 13 different change of specification with entry needle, be black like the entry needle of 22G, the color of pressing hands also is black; The entry needle of 23G is blue, and the color of pressing hands also is blueness or the like.
As shown in Figure 3, the use of automatic retracting type safety self-destruct disposable syringe is: open safety plate, safety plate promptly fractures; Extract required injection drug push back get rid of bubble after, inject; The conical grab 14 in needle tubing seat 2 rear ends punctures plug 5 when injection finishes; Snap in stopping ring 15; And push the draw-in groove 9 that spring base 7 makes snap ring 8 disengaging injection core rods 10 inboards of spring base 7 lower ends, thereby make spring 6 smoothly needle holder 2 and needle tubing 1 to be drawn in the cavity of injection core rod 10.At this moment, the syringe repeated use of can't disintegrating, the entry needle of crossing with medicinal liquid and contact patients all is stored in the tube of core bar, accomplishes retraction safety self-destruct function automatically, reaches the safety self-destruct purpose.
