Embodiment
The utility model is further illustrated with reference to the accompanying drawings and detailed description.
Shown in as shown in Figure 1 to Figure 4, it is described in the utility model can automatic pipe sealing disposable syringe device, including injection
Device body, the syringe body include syringe 1 and piston push rod 2, in addition to interlocked injection mechanism, the interlocked injection mechanism
Including holder 3, travelling gear 4 and slide bar 5, driven rack 6 is provided with slide bar 5, is set on the periphery wall of the syringe 1
Be equipped with active rack 7, the slide bar 5 is movably disposed on the holder 3, the travelling gear 4 rotatably arranged with
On holder 3, and the side of the travelling gear 4 is engaged with the driven rack 6 on slide bar 5, the opposite side of travelling gear 4
It can be engaged after being passed out of holder 3 with the active rack 7 on the outer wall of syringe 1；And when travelling gear 4 simultaneously with it is described driven
After rack 6 and the active rack 7 engagement, the mobile trend direction of driven rack 6 relative to active rack 7 mobile trend side
To opposite；Pressing down section 9 is formed after one end bending corresponding with the push handle end 8 of piston push rod 2 on slide bar 5, the pressing down section 9 can
Withhold on the push handle end 8.
Disposable syringe device described in the utility model mainly makes when needing to carry out tube sealing after retention needle infusion terminates
With it is specifically using process：Load a certain amount of dilution heparin liquid in the syringe 1 of syringe body first, afterwards will
Needle tip 10 is pierced into during corresponding heparin emits, and a certain amount of dilution heparin liquid is injected into then being emitted to heparin, and need
To retain a certain amount of dilution heparin liquid in syringe 1, in case being injected when taking pin；Afterwards by linkage described in the utility model
Injection mechanism is attached cooperation with syringe body, and then medical worker grips holder 3 on the other hand makes it as far as possible fixed,
And another hand then grips syringe 1 and carries out taking pin to operate, during pin is taken, transmission is driven by the active rack 7 on syringe 1
Gear 4 rotates, and then drives the driven relative motion of rack 6, i.e. band moving slide-bar 5 moves, and slide bar 5 is due to by under its pressing down section 9
It is pressed on the push handle end 8 on piston push rod 2, therefore the injection operation that syringe body can be made to be linked, realized and taken with this
Interlocked injection purpose during pin.Therefore the utility model may be implemented in the automatic pipe sealing operation taken during pin, can be effective
Ground avoids the situation of the backflow of blood caused by taking pin from occurring.
In addition, described in the utility model " the mobile trend direction of driven rack 6 relative to active rack 7 movement
Trend is in opposite direction ", mobile trend direction therein, refer to being operated in progress tube sealing for driven rack 6 and active rack 7
Moving direction in journey, the specific example shown in accompanying drawing 3 specifically being can refer to, it needs to take pin upwards during pin is taken,
Need to drive syringe 1 to move up, now active rack 7 is to move up；And because holder 3 is stationary state, therefore
The mobile of active rack 7 will rotate with nutating gear 4, and then drive the driven rack 6 in left side to be moved down together with slide bar 5,
The final interlocked injection purpose for realizing syringe body.
Certainly, without loss of generality, except one travelling gear 4 of only setting referring to the drawings shown in the utility model
Beyond situation, the also settable single travelling gear 4 of gear set in place being made up of multiple travelling gears, as long as ensuring accordingly
Syringe body can be made to carry out interlocked injection operation during pin is taken.Also, in theory, by using gear set in place
After single travelling gear 4, specific gearratio can be also realized by gear train, that is, realizes both driven rack 6 and active rack 7
The certain ratio relation of amount of movement.Such as by using gear train, the amount of movement and active rack 7 of driven rack 6 are preferably set
The ratio between amount of movement be more than 1, i.e., when carrying out taking pin to operate, the amount of movement of active rack 7 is by less than the movement of driven rack 6
Amount；It is 1.2 that the ratio between the amount of movement of driven rack 6 and the amount of movement of active rack 7, which such as can be set, now when active rack 7 moves 1
During unit quantity, driven rack 6 will mobile 1.2 times of unit quantities.In addition, the feelings of a travelling gear 4 are only set in referring to the drawings
Under condition, the ratio of the amount of movement of its driven rack 6 and active rack 7 is 1, when exemplified by the structure as shown in by accompanying drawing 3, works as master
When carry-over bar 7 moves up 1 unit quantity, driven rack 6 will move down 1 unit quantity.
Certainly, without loss of generality, it is preferably arranged between the interlocked injection mechanism in the utility model and syringe body
Detachable connection structure, as shown in Figure 1, only when needed just by interlocked injection mechanism and syringe sheet under such a structure
Body is connected, and needs to make pressing down section 9 withhold on push handle end 8 accordingly, while make drive gear 4 and active rack 7
Engagement.Certainly, it may also set up and be structure as a whole between interlocked injection mechanism and syringe body, pressing down section 9 can such as be withheld
On push handle end 8 and it is fixedly connected or directly slide bar 5 and the setting of piston push rod 2 is structure as a whole, while remains driving
Gear 4 and the meshing relation of active rack 7.
In addition, in order that the power that is applied on piston push rod 2 of slide bar 5 is consistent with the moving direction of piston push rod 2, this reality
Generally the mobile trend direction of driven rack 6 should when in use put down with the mobile trend direction of active rack 7 with new
OK；As shown in Figure 3, the mobile trend direction of driven rack 6 and the mobile trend direction of active rack 7 are in vertical side
To.
