Detailed description of the invention
Reach, by the present invention is expanded on further, technological means and effect that predetermined purpose is taked, below in conjunction with drawings and Examples detailed description of the invention, architectural feature and effect thereof to the present invention, describe in detail as follows.
Embodiment 1:
In order to solve existing syringe only one of which needle stand, in use need repeatedly to pull out pin, the inconvenience that contact pin is brought, and it is susceptible to the problem that antibacterial infects, the invention provides a kind of such as Fig. 1 multifunctional combination three needle stand syringe, including syringe 1, it is arranged at the needle stand 3 on syringe 1 top, it is arranged at the core bar 2 of syringe 1 bottom, one end that described core bar 2 is placed in syringe 1 is provided with piston 5, the other end is placed in outside syringe 1, and it is provided with baffle plate 6, described needle stand 3 is provided with three, it is respectively the first needle stand 3-1, second needle stand 3-2, 3rd needle stand 3-3, for regulating the liquid controlling to flow into or from syringe.
As shown in figure 13, in order to make three needle stands 3 can the most quickly connect corresponding medical instruments, avoid occurring mutually to collide, the phenomenon that impact uses, above-mentioned syringe 1 could be arranged to ellipse, first needle stand 3-1, the second needle stand 3-2, the 3rd needle stand 3-3 so can be sequentially arranged the top being arranged at syringe 1, the most attractive in appearance but also have bigger gap each other, provide convenient for connecting matching appliances.
These three syringes are possible not only to realize the function of existing syringe, and it is being connected to matching used connection assembly or other medical appliances, can be to realize new function, achieve feed liquor, go out the recycling of liquid, avoid because frequently contact pin, pull out pin and the problem that causes antibacterial to infect, reduce the misery that patient is caused, and easy and simple to handle.
Realize the function of existing syringe, one or two needle stands 3 that the limitation card anti-reduction cap 8 shown in 23 or Fig. 6 shown in Fig. 9 completely encloses in three needle stands 3 can be used, it is ensured that the safe handling of syringe.
The when of realizing New function, connect for convenience, adapter sleeve 10 can be set on needle stand 3, and connection screw thread 11 is set at the inwall of adapter sleeve 10, fluid passage 9 is arranged at adapter sleeve 10 internal, so can with various medical instruments quickly, connect flexibly.
Above three needle stand 3 is respectively connected with automatic pressure check valve 12 for being controlled the liquid flowing into or from syringe, guarantee backflow phenomenon, achieve feed liquor, go out the recycling of liquid, it is to avoid because frequently contact pin, pull out pin and the problem that causes antibacterial to infect, bring great pain to patient.
As shown in Figure 4, automatic pressure check valve 12 can be fixedly installed between needle stand 3 and syringe 1, the flow liquid direction of this setup automatic pressure check valve 12 determines that, cannot be carried out changing, needle stand 3 is feed liquor or goes out liquid it has been determined that cannot be carried out changing, and this setup is bigger to the use restriction ratio of this reverse syringe.
If in above-mentioned first needle stand 3-1, the 3rd needle stand 3-3, automatic pressure check valve 12 is set, two medical instruments as shown in Fig. 8, Fig. 9, Figure 10, Figure 11 can be connected, for the liquid flowing into or from syringe is controlled, it is achieved the application of difference in functionality；Second needle stand 3-2 is provided with leakproof and emits 8, as shown in Figure 6, for aerofluxus, liquid feeding, so can be discharged in syringe 1 by the air in the syringe 1 of multifunctional combination three needle stand syringe, it is not necessary to travel frequently over the interface being connected with needle stand 3 and carry out the discharge of air；And air vent is well closed by anti-reduction cap 8, it is ensured that the phenomenon of leakage will not occur.
Embodiment 2:
