More than the worker of the operation of Shuo Ming syringe of the present invention and each several part can will make an explanation to the explanation of the different conditions of syringe shown in Figure 6 according to Fig. 1.
State shown in Fig. 1 is transportation and the stored condition of syringe of the present invention before using.
When syringe will be used to inject, at first pull back catch bar 7 with the suction injection, as shown in Figure 2 in common mode.
It is that the edge 15 of parts 12 is near the edge of ring-shaped article 22 or a little till some that syringe generally is filled into when piston rod is in following position.The relative length of the various parts of syringe is such.Maximum perfusion volume corresponding to the maximum retracted length of catch bar is a bit larger tham actual injected dose.Therefore, the air of staying in the liquid can be eliminated near annular groove 18 to safety device 20 by promoting catch bar downwards, as shown in Figure 3.When with the state of syringe shown in Figure 1 relatively, the piston rod of being made up of catch bar 7 and connector 8 is to be on the same position as can be seen, piston 4 then forwards on the position of base 21 near the additament 10 of connector.Should note, this rotation is brought by configuration of the present invention, and its allows piston 4 in original state to be positioned on as shown in Figure 1 its extreme lower position, therefore, it need after the perfusion to have reduced the air capacity of discharging from syringe, particularly reduced the volume of entry needle passage.Thus, the discharge of air will be faster easier than existing syringe.In the syringe of prior art, it is essential that the air of certain volume exists in the original state of syringe, and this is because piston can not be in the bottom of cylinder before perfusion.
When injecting, can carry out what is called " vein test " earlier, to determine not exist blood and definite thus entry needle in patient tram on one's body at the entry needle internal memory.For this " vein test ", catch bar bounces back on position shown in Figure 2 more a little, thus, when entry needle is rolled into human body, can draw small amount of liquid on one's body from patient.In order then to inject the whole liquid that inject in the syringe, remove safety device 20 from catch bar, push away downwards simultaneously, up to final position as shown in Figure 4, after whole injection finishes, transfer to syringe also can abandon it.
Figure 5 shows that after injection for the first time people attempt to pour into once more with drawing back catch bar syringe.Connector 8 arrives certain position with catch bar 7 earlier.In this position, the edge part of parts 12 and the side edge of groove 19 are closed.Stopped that thus connector further moves up.Also has an additional safety measure in the present embodiment, it is such, cavity 13 expanded radially when being in position shown in Figure 5 of elastic component 12, and elastic edge enters groove 19 along part, and the coaxial constriction part of catch bar 7 from connector 8 separately, when attempting further to bounce back.The physical end position of approaching piston 4 is preferably chosen in the position, edge of groove 19, and therefore, piston can only be done a very little motion that makes progress from position shown in Figure 5, promptly till the bottom of piston 4 touches the additament of connector 8.This perfusion that just means syringe is not only because to draw back catch bar be impossible, and any opening of attempting the cylinder of this side by entry needle to act on piston also be impossible.
Fig. 6 represents that another kind of type attempts to use the state of exhausted syringe, does not promptly inject whole liquid measures, thus, does not also just arrive the final position that piston is blocked.Yet, catch bar 7 upwards bounces back from the position that connector 8 does not engage with groove 19 as yet, elastic barrier part 12 will close with the side edge of second groove 18 that places groove 19 to go up slightly, on this position, when retraction force is applied on the catch bar 7, catch bar 7 as shown in fig. 5 like that no longer being connected with connector 8, therefore, can not also just can not increase liquid with catch bar 7 piston 4 that moves up, inject syringe with extracting.Syringe of the present invention is disposable fully.
Shown in Figure 7 is another but similar embodiment of the present invention, and it illustrates the original state according to the syringe of present embodiment corresponding to Fig. 1.In this case, the catch bar and the coupling part of piston rod are made in one, rather than separable.Piston rod has a top and promotes part 37, stop portions 39, rod part 38 and additament 40.The profile of Fig. 8 is represented stop portions 39 especially, comprises, for example four parts that are divided into by little radial slit, and the groove on cylinder 31 inwalls of present embodiment form elastic barrier partly.Particularly the inwall of cylinder 31 comprises groove 41 and 42, and the internal diameter that is increased cylinder by step ground forms, and the direction that internal diameter increases is towards the cylinder bottom that contains piston component 34.Elastic barrier part 39 and identical as the embodiment of the front together mode combined effect of groove 41 and 42 edges, therefore, the use of syringe is actually identical.Said their main difference is by can not the causing from property of catch bar 37 and coupling part 38 from the front, therefore, does not have as previously described the add-on security device by Fig. 5 and connector shown in Figure 6 in the present embodiment.The stepped construction that should be noted that groove 41 and 42 helps syringe cylinder with the injection moulding manufacturing and reduced cost.Another structural difference that may reduce cost comprises with plastics makes the piston body part, and different rubber or other similar material, and loads onto two zero shapes circles 35 and 36 on piston, and perhaps other sealing member is to provide necessary tightening up.
The illustrated various architectural features of the embodiment of Fig. 7 also can separately be used or be used in combination with the embodiment of Fig. 1.Basic function advantage of the present invention promptly particularly can prevent to re-use and keep high dependability fully safely, no matter with any combination or with any similar enforcement, they all belong to the scope that following claim is protected.
