Description
Technical field
It is a kind of syringe particularly the present invention relates to a kind of medical supplies.
Background technology
When medical personnel extract liquid medicine using syringe, minute bubbles are frequently accompanied by pharmaceutical liquid, for one
A little medicines for needing to mix in advance, are needed to rock before extraction, are well mixed, and the bubble in syringe is caused in this case
It is more；Conventional syringe extract liquid after, it is necessary to syringe needle stand or flick upward the barrel of syringe so that bubble float on
At syringe needle, by promoting piston to discharge gas；This injector operations trouble, has a strong impact on injection efficiency, while in gas
Some drugs liquid can be wasted during bubble discharge.
The content of the invention
In view of the above-mentioned problems, the present invention provides a kind of gas-liquid separation syringe, the syringe can say the interior of syringe
Bubble coalescence, separates gas in injection process, effectively improves injection efficiency.
To solve the above problems, the technical solution adopted in the present invention is：This gas-liquid separation syringe includes a bottom and opened
Syringe provided with pin hole, is provided with the piston that can be slided up and down along the barrel of syringe in the syringe；Pacify at the pin hole
Equipped with buoyancy switch；Air dividing plate is fixed with the cylinder bottom of the syringe, being provided with the air dividing plate can be along the syringe
The wind wheel that axis is freely rotated.
The beneficial effects of the invention are as follows：Under nature, the buoyancy switch is in closed mode, and now syringe is in sealed shape
State, the structure ensure that the cleaning inside syringe；When needing to extract liquid, stirring piston reduces air pressure in syringe,
Buoyancy switch is opened in the presence of air pressure, and liquid enters in syringe；Liquid flows after pin hole is entered at the wind wheel on air dividing plate
Cross, liquid drives wind wheel rotation；There is bubble with what liquid entered, bubble is in spout under the drive of natural buoyancy and wind wheel
Wind shape floats to syringe, and the bubble for being partly adhered to syringe barrel floats to syringe during liquid in rotation；Top
Bubble collect and be fused into air layer；In injection process, pin hole is injected down；Because buoyancy switch is dipped in water and is kept
Open, now liquid can be injected smoothly, and wind wheel rotates under the drive of liquid；But in injection latter stage, with subtracting for liquid
Few, wind speed round is gradually reduced, and when liquid gradually flows net, buoyancy switch is progressively closed off, and after liquid injection is complete, buoyancy is opened
Close and by the gas partitions in syringe, effectively prevent gas from injecting human body.
The present invention is easy to operate, and the bubble in syringe need not be adjusted after liquid is extracted, and the present invention can in injection
It is enough to be about to gas barrier certainly；When extracting liquid, by the rotation of wind wheel, the present invention can to the further stirring of liquid, mixing,
So that medicine is evenly；The speed and injection progress of injection can easily be observed by the rotation for observing wind wheel；It is of the invention big
Injection efficiency is improved greatly, the operating pressure of medical personnel is alleviated.
Preferably, the buoyancy switch includes the fluid dividing cover that is fixed at pin hole and in the fluid dividing cover
Buoyancy plate；Fluid hole is offered on the fluid dividing cover；The buoyancy plate can just divide to the pin hole and along the axis of pin hole
Flow cover slide over side walls；When not having liquid, buoyancy plate falls and blocks pin hole under gravity, now needle cylinder airtight；
After liquid is extracted in syringe, buoyancy plate floats and opens pin hole, now can normal infusion；When the liquid injection in syringe is finished
When, buoyancy plate falls and closes pin hole under gravity, effectively prevents the gas in syringe from entering pin hole.
Preferably, the plate face that the air dividing plate presses close to a bottom is the cambered surface caved inward；In order to will be from pin hole inspiration
Bubble be pooled to the center of air dividing plate, be easy to air dividing plate to stir bubble, collect.
Preferably, scribbling colour bar on the wind wheel；The speed rotated by wind wheel can learn the fast of liquid injection
Slowly；If the rotation of wind wheel is slack-off when the dynamics of pushing syringe is constant, you can learn that syringe will inject liquid, colour bar
The rotation of wind wheel can be made more eye-catching.

Embodiment
Embodiment
In the embodiment shown in Fig. 1, Fig. 2, this gas-liquid separation syringe includes the syringe that a bottom offers pin hole 11
1, the piston 2 that can be slided up and down along the barrel of syringe 1 is installed in the syringe 1；Buoyancy is installed at the pin hole 11
Switch；The buoyancy switch includes the fluid dividing cover 3 being fixed at pin hole 11 and the buoyancy plate 4 in the fluid dividing cover 3；
Fluid hole 31 is offered on the fluid dividing cover 3；The buoyancy plate 4 can just divide to the pin hole 11 and along the axis of pin hole 11
Stream 3 slide over side walls of cover；Be fixed with air dividing plate 5 at the cylinder bottom of the syringe 1, the plate face that the air dividing plate 5 presses close to a bottom be to
The cambered surface of sunken inside；The wind wheel 6 that can be freely rotated along the axis of the syringe 1 is installed on the air dividing plate 5, in the wind
Colour bar is scribbled on wheel 6.
Under nature, the buoyancy plate 4 blocks pin hole 11 under gravity, and now pin hole 11 is in closed mode,
Now syringe 1 is in air-tight state, and the structure ensure that the cleaning inside syringe 1；When needing to extract liquid, piston 2 is stirred
Reduce air pressure in syringe 1, the buoyancy plate 4 is opened under the influence of air pressure, and liquid enters pin from the fluid hole 31 of fluid dividing cover 3
Cylinder 1；Liquid flows through after pin hole 11 is entered at the wind wheel 6 on air dividing plate 5, and liquid drives wind wheel 6 to rotate；Enter with liquid
Also have bubble, bubble floats to syringe 1 under the drive of natural buoyancy and wind wheel 6 in cyclone shape, is partly adhered to pin
The bubble of 1 barrel of cylinder is floatd during liquid in rotation to the top of syringe 1；The bubble at top collects and is fused into air layer；
In injection process, pin hole 11 is injected down；Because buoyancy plate is dipped in liquid, kept it turned in the presence of buoyancy, now liquid
Body can be injected smoothly, meanwhile, wind wheel 6 rotates under the drive of liquid；But in injection latter stage, with the reduction of liquid, wind
Taking turns 6 rotating speeds gradually reduces, when liquid gradually flows net, and the position of buoyancy plate 4 is gradually reduced and blocks pin hole 11, works as liquid injection
After completely, buoyancy switch is closed, and now the gas in syringe 1 is separated, and effectively prevents gas from injecting human body.
The plate face that air dividing plate 5 in the present embodiment presses close to a bottom is the cambered surface caved inward；The structure can be by from pin hole
The bubble of inspiration is pooled to the center of air dividing plate, i.e., all bubbles pass through the agitation of wind wheel 6, can effectively facilitate bubble rotation
Turn to rise and collect.
The present invention it is easy to operate, extract liquid when, the bubble entered with liquid can quick collecting to the end of piston 2,
In injection, this syringe can be automatically separated bubble and liquid, without adjusting the bubble in syringe, effectively improve injection effect
Rate；When extracting liquid, by the rotation of wind wheel 6, the present invention can be to the further stirring of liquid, mixing so that medicine is more equal
It is even；In addition, can easily be observed in the speed and injection progress of injection, the present embodiment in wind by the rotation for observing wind wheel 6
Colour bar is scribbled on wheel, the rotation of wind wheel can be made more eye-catching；The present invention substantially increases injection efficiency, alleviates medical personnel's
Operating pressure.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc. should be included in the scope of the protection.
