Baffle 6 is connected and sealed, and bacterium or virus can not generate infection.
Or following connection type is used, secluding film 4 is fixed.First groove 18 is set to 6 bottom surface of baffle, it is described every
The lower end of exhausted film 4, it is fixed by the first rubber ring 7 coincideing with the first groove 18;The upper end of secluding film 4 and second baffle 17 are solid
Secluding film 4 can be separated by the first rubber ring 7 with core bar 2 in this way, be carried out disinfection, to reuse by fixed connection.
As shown in Fig. 2, 6 top surface of baffle is provided with the first groove 18, the lower end of the secluding film 4 by with it is first recessed
The first identical rubber ring 7 of slot 18 is fixed;The lower section of second baffle 17 is provided with cricoid second groove 19, the secluding film 4
Upper end, fixed by being sheathed on core bar 2 second rubber ring 16, this mode can equally prevent bacterium or virus from generating
Infection, except that secluding film 4 needs to be sheathed on the first rubber ring 7 and the second rubber ring 16, if on secluding film 4,
Lower both ends setting prevents the protrusion for being detached from the first rubber ring 7 and the second rubber ring 16, can play better seal effect, Er Qieke
Eaily to replace secluding film 4.
Or use connection type as shown in Figure 3, first groove 18 is set to the top surface of baffle 6, core bar 2 it is outer
It encloses, is provided with cricoid first groove 18, the lower end of the secluding film 4 passes through first rubber ring 7 identical with the first groove 18
It is fixed;The upper end of secluding film 4 is fixedly connected with second baffle 17.This connection type is equally applicable to nonexpondable injection
Device uses, in case the medical fluid used before core bar 2 or 1 internal residual of syringe, pollutes subsequent new medical fluid.
Embodiment 4:
As shown in fig. 7, the reverse syringe of the combination of the self-regulating function is additionally provided with exhaust outlet 14, which is set
It is placed in the top of syringe 1, and is threaded with leakproof cap 8 at the gas outlet of the exhaust outlet 14.It can will be self-regulated in this way
In air discharge syringe 1 in the syringe 1 of the reverse syringe of combination of function, does not need to travel frequently over and connect with what needle stand 3 was connect
Mouth carries out the discharge of air;And leakproof cap 8 can close exhaust when not needing exhaust outlet 14 and being exhausted well
Mouth 14, it is ensured that the phenomenon of leakage will not occur.
Or as shown in Figure 5, Figure 8, exhaust outlet 14 is set on connector 15, equally can be quickly discharged in syringe 1
The air in portion, without by contact pin, pull out needle air be discharged.
Embodiment 5:
As shown in figure 9, the reverse syringe of the combination of the self-regulating function is connected with perfusion tube 20, the automatic pressure list
It is set on perfusion tube 20 to valve 12.It in this way can be when rescuing patient by one of the reverse syringe of combination of self-regulating function
Needle stand 3 connect injection needle, another needle stand 3 connect perfusion tube 20, the hydrops of patient's body can be extracted, without pull out repeatedly needle,
Contact pin, complete drawing liquid, will not enter air, i.e., safety and conveniently, whole process sterile working.
The reverse syringe of combination of the self-regulating function is connected with puncture 24 as shown in Figure 10, the automatic pressure list
It is set to valve 12 in the connecting tube for puncturing 24.It is worn when two needle stands 3 of the reverse syringe of combination of self-regulating function are all connected with
When piercing 24, and 24 two liquid bottles of insertion are punctured by two, sterile virus-free efficient liquid separation may be implemented.
The reverse syringe of combination of the self-regulating function is connected with transfusion needle 25 as shown in figure 11, the automatic pressure
Check valve 12 is set in the connecting tube of transfusion needle 25, if two needle stands 3 of the reverse syringe of combination of the self-regulating function
The sterile quick blood transfusion of same blood group can be realized by being all connected with transfusion needle 25, and can be pushed and pulled core bar 2 repeatedly and be realized a contact pin
Repeatedly effectively blood transfusion.
The reverse syringe of combination of the self-regulating function is connected with perfusion tube 20 as shown in figure 12, and perfusion tube 20
Both ends be provided with and open connector 26 or the setting of described perfusion tube one end opens connector 26, other end setting is threadedly coupled
Mouth 13 as shown in figure 13, can thus be cooperated, the combination of the self-regulating function is reverse with infusion pump or infusion pump
Syringe on one side connect puncture 24 while connect infusion bottle, may be implemented to push and pull repeatedly it is laborsaving, pressurize liquid feeding when without air enter,
Sterile to be rapidly completed, reduction avoids leakage, reduces pollution, reduces the dosage environmental protection of syringe, and save the cost takes up space be convenient for less
It carries.
The reverse syringe of combination of the self-regulating function is connected with injection needle 30 as shown in figure 15, the automatic pressure
Check valve 12 is set on the attachment base of injection needle 30, is used cooperatively with puncture 24, perfusion tube 20, transfusion needle 25, is completed continuous
Injection perhaps continuous drawing liquid and be not susceptible to bacterium or germ infection, reduce and pull out the number of needle, contact pin, reduce patient
Pain.
Embodiment 6:
Institute from embodiment 1 to embodiment 5 is functional and applies, and is inverse by the combination of the self-regulating function of double needle seat
It is completed to syringe.This is a kind of implementation, in addition to this, can also be by using Y type perfusion tube as shown in FIG. 6
