Description
Technical field
The utility model relates to a kind of medical instrument, in particular to a kind of drawing liquid auxiliary device.
Background technique
In the common diagnostic techniques of medical treatment, it usually needs extract blood of human body, tissue fluid and body fluid using syringe.Existing skill
Drawing liquid is generally completed by medical staff's operating syringe in art, and during drawing liquid, medical staff needs to fix syringe front end on the other hand, and one
It pulls dynamic cylinder piston bar and carries out drawing liquid, drawing liquid mode operation convenience is poor, it is more difficult to accurately control the amount of liquid of extraction.And it is needing
When largely extracting liquid, medical staff's operating time is long, and the physical strength to operator is huge challenge.
Utility model content
In view of this, the purpose of the utility model is to provide a kind of novel drawing liquid auxiliary device, to solve in the prior art
Medical staff using syringe extracts blood of human body, tissue fluid or there are operation conveniences when body fluid poor, more difficult accurately controls pumping
The technical problems such as the amount of liquid and drawing liquid that take be laborious.
The utility model drawing liquid auxiliary device including two guide rods being arranged in parallel, is fixed on the syringe card of guide rod front end
It covers, be fixed on the handle of guiding rod rear end and the piston fixture block that can be slided on the guide bar and along guide rod, the work are set
Fork clip block is between syringe cutting ferrule and handle；
Be provided on the syringe cutting ferrule with syringe outer surface cooperation semi-cylindrical locating slot and with back end of syringe edge
On flange cooperation limit card slot；
It is provided on the piston fixture block with the T shape card slot of cylinder piston rear end cooperation and for cooperating with operator's finger
Hole；
The ring set for preventing syringe from deviating from from semi-cylindrical locating slot, the ring set are also cased with outside the syringe cutting ferrule
With syringe cutting ferrule detachable connection.
Further, the guide rod is screw rod, and the spiral shell for limiting piston fixture block shift position is provided on the screw rod
It is female.
The utility model has the beneficial effects that
The utility model drawing liquid auxiliary device, when use, first determine the semi-cylindrical that the syringe of syringe is placed on syringe cutting ferrule
In the slot of position, and by the flange on back end of syringe edge in limit card slot, and by cylinder piston rear end embedded in piston fixture block
On T shape card slot in, then ring set covered on syringe cutting ferrule to fix syringe, then connect syringe with puncture needle,
It can carry out drawing liquid.Operator holds handle when drawing liquid, and inserts a finger into the hole on piston fixture block the work for pulling syringe
Plug, can extract liquid out, and drawing liquid operates a hand and can be completed, simple to operate；And it is similar to and pulls during drawing liquid
Trigger does not easily cause operator tired, can more accurately control drawing liquid amount yet convenient for exerting oneself and controlling piston traveling speed.And
And this drawing liquid auxiliary device using when need not be fixed on a certain position, using flexible, in use at drawing liquid auxiliary device
It will not all deviate from from syringe cutting ferrule in any angle syringe, use is safe.
Detailed description of the invention
Fig. 1 is the schematic perspective view of novel drawing liquid auxiliary device；
Fig. 2 is the combining structure schematic diagram of drawing liquid auxiliary device and syringe.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As shown, the novel drawing liquid auxiliary device of the present embodiment, including two guide rods 1 being arranged in parallel, is fixed on and leads
To bar front end syringe cutting ferrule 2, be fixed on guiding rod rear end handle 3 and setting on the guide bar and can along guide rod cunning
Dynamic piston fixture block 4, the piston fixture block is between syringe cutting ferrule and handle.
Be provided on the syringe cutting ferrule with syringe outer surface cooperation semi-cylindrical locating slot 5 and with back end of syringe edge
On flange cooperation limit card slot 6.
It is provided on the piston fixture block with the T shape card slot 7 of cylinder piston rear end cooperation and for matching with operator's finger
The hole 8 of conjunction.
The ring set 9 for preventing syringe from deviating from from semi-cylindrical locating slot, the ring are also cased with outside the syringe cutting ferrule
Set and syringe cutting ferrule detachable connection.
Drawing liquid auxiliary device can be used for but be not limited to bone marrow aspiration drawing liquid, thoracentesis, abdominocentesis, pass in the present embodiment
Chamber tapping etc. is saved, versatility is good.
Using when drawing liquid auxiliary device drawing liquid, first the syringe 11 of syringe 10 is placed on syringe cutting ferrule in the present embodiment
Semi-cylindrical locating slot in, and by the flange 12 on back end of syringe edge in the limit card slot, and by cylinder piston 13
Rear end in T shape card slot on the piston fixture block, then by 9 sets of ring set on syringe cutting ferrule 2 to which syringe be fixed, then will
Syringe is connect with puncture needle, can carry out drawing liquid.Operator holds handle when drawing liquid, and inserts a finger on piston fixture block 4
Hole 8 in pull syringe piston, liquid can be extracted out, drawing liquid operate a hand can be completed, it is simple to operate；And
It is similar to cocking during drawing liquid, convenient for exerting oneself and controlling piston traveling speed, does not easily cause operator tired, it also can be more
Accurately control drawing liquid amount.And this drawing liquid auxiliary device using when need not be fixed on a certain position, using flexible was using
Drawing liquid auxiliary device is in any angle syringe in journey will not all deviate from from syringe cutting ferrule, and use is safe.
The guide rod 1 is screw rod as a further modification of the present embodiment, is provided on the screw rod for limiting piston card
The nut 14 of block shift position.Before drawing liquid, nut is adjusted to correct position, then pulls piston fixture block drawing liquid again, when
When piston fixture block touches nut, drawing liquid is completed, and the moving distance of piston fixture block is limited by nut, does not have to observation piston in needle
Position in cylinder also can guarantee the accuracy of drawing liquid amount, and drawing liquid efficiency can be improved, further reduced drawing liquid operation difficulty.
Finally, it is stated that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng
The utility model is described in detail according to preferred embodiment, those skilled in the art should understand that, it can be to this
