By Fig. 1, present embodiments provide a kind of vacuum blood sampler, including blood collection device 100, vacuum buffer device
200, negative pressure generator 300, blood sampling knife 400, mobile dolly 500.Wherein blood sampling knife 400 respectively with anticoagulant adding apparatus 600,
Blood collection device 100 connects.Blood collection device 100 is connected with vacuum buffer device 200 again, vacuum buffer device 200 with
Negative pressure generator 300 connects.Wherein blood collection device 100 and vacuum buffer device 200 are all disposed within mobile dolly 500.
The device of the directly blood sampling work in the present invention is blood sampling knife 400, is put by blood sampling knife 400 and carries out at the blood vessel of blood sampling object
Blood sampling.Anticoagulant adding apparatus 600 is connected with blood sampling knife 400, and the effect played is while blood sampling knife 400 is taken a blood sample
A certain amount of anticoagulant is added to blood sampling knife 400, makes the blood of collection is added with anticoagulant.
The blood sampling power source of the present invention is negative pressure, and negative pressure is produced by negative pressure generator.Refering to Fig. 2, in the present embodiment
Negative pressure generator 300 is vacuum pump, and vacuum pump is connected with vacuum buffer tank 201, when vacuum pump works by vacuum buffer tank 201
Carrying out evacuation process, vacuum buffer tank 201 is connected with blood collecting tank 110, blood collecting tank 110 is carried out evacuation simultaneously
Process.Two tank bodies are made to be true dummy status.
Negative pressure is connected with vacuum buffer device 200 by negative pressure generator 300, vacuum buffer device 200 and blood collecting
Device 100 connects, and blood collection device 100 is connected with blood sampling knife 400 again.Depression generator provides certain negative pressure, makes mutually
The vacuum buffer device 200, blood collection device 100 and the blood sampling knife 400 that are connected are filled with negative pressure, are made by the negative pressure produced
Blood flow to blood collection device 100 through blood sampling knife 400.The effect of vacuum buffer tank 201 is to maintain negative pressure and collects blood
The blood foam overflowed in collection device 100.
It is to put at a moveable dolly referring again to Fig. 1, blood collection device 100 and vacuum buffer device 200
On.Mobile dolly 500 has mobility the most flexibly, and blood collection device 100, vacuum buffer device 200 can be made necessarily
In the range of move.
Refering to Fig. 2, blood collection device 100 includes blood collecting tank 110, blood collecting tank 110 respectively with blood sampling knife 400
Connect with vacuum buffer device 200.The bottom of blood collecting tank 110 is provided with magnetic stirring apparatus 120, and magnetic stirring apparatus 120 will
The lower part of blood collecting tank 110 is wrapped up, and the rotor of magnetic stirring apparatus 120 is arranged in blood collecting tank 110.Magnetic force stirs
The lower end mixing device 120 is provided with blood electronic scale 131.The effect of magnetic stirring apparatus 120 is to the blood in blood collection device 100
It is stirred, makes the blood of collection will not produce the phenomenon of solidification.Because being magnetic stirring apparatus, the rotation utilizing magnetic force is former
Reason, it is not necessary to arrange stirring rod in blood collecting tank 110, this reduces to a certain extent and arranges metallics in tank and make
The probability of the pollution become.The blood electronic scale 131 that magnetic stirring apparatus 120 lower end is arranged is to adopting in blood collection device 100
The device that the weight of the blood of collection is acquired, can draw the blood of section any time by the peeling function of blood electronic scale 131
The weight that liquid gathers, it is achieved more accurate acquisition controlling.Anticoagulant tank 601 lower end is provided with anticoagulant Weight acquisition device 610,
The anticoagulant weight of any time section can be acquired.
Seeing also Fig. 1 and Fig. 2, vacuum buffer device 200 includes vacuum buffer tank 201, and vacuum buffer tank 201 is respectively
It is connected with blood collecting tank 110 and negative pressure generator 105.The Main Function of vacuum buffer tank 201 is to collect by blood collecting tank
The blood foam overflowed in 110 and the negative pressure keeping blood sampling system entirety.Because during blood flows, the motion liquid of higher speed
Carry out collision between body and can produce a certain amount of foam, and the feature of this foam is to have bigger volume, and the short time
In will not rupture.The upper end that will produce blood collecting tank 110 in this case have accumulated the sight of one layer of foam, along with blood
Liquid constantly injects in blood collecting tank 110, and a part of foam overflow blood collecting tank 110 also flow in vacuum buffer tank 201
Deposit.So wanting periodically vacuum buffer tank 201 to be carried out discharge opeing work, prevent in vacuum buffer tank 201 because of collection
The more phenomenon overflowed that produces of blood foam is back to the phenomenon in blood collecting tank 110.
Seeing also Fig. 1 and Fig. 2, anticoagulant adding apparatus 600 includes anticoagulant tank 601, anticoagulant tank 601 and blood sampling
Cutter 400 is connected.
Place in anticoagulant tank 601 is anticoagulant, because containing a large amount of albumen and thrombin in blood, thus can make
Blood is become gelatin clot from the liquid of flowing shape under external environment condition.Blood under curdled appearance also cannot realize stream again
Dynamic state, so, in collecting blood, the situation of solidification to occur anti-Hemostatic Oral Liquid.And anticoagulant can stop blood by flowable state
Transfer the solid-state of jelly to.The effect being added anticoagulant at blood sampling knife 400 blood sampling will be far better than at blood collecting tank 110
The effect of middle addition anticoagulant.First, blood sampling knife 400 is direct blood-taking device, and its blood touched is to be not exposed to outside
Blood, there is not the situation of any solidification.Second, flow into the blood in blood collecting tank 110 through certain time
Flowing and carried out the blood stored, when storing, blood is in immobilising state, and this state more accelerates blood
The cure of liquid, makes the anticoagulant blood that the most do not plays a role just carry out solidifying.Do not have this effect having of anticoagulant.
So, anticoagulant tank 601 is connected by the present invention with blood sampling knife 400, make anticoagulant the time at first the most with extraction
Blood generation effect, reduces the risk of blood coagulation in the very first time.
Refering to Fig. 2, blood sampling knife 400 is connected with anticoagulant tank 601 and blood collecting tank 110 respectively.The work of blood sampling knife 400
It is the collection directly carrying out blood, and the blood gathered is inputted to blood collecting tank 110 by the effect of negative pressure.Because adopting
Blood cutter 400 is connected with anticoagulant tank 601, so being added in the lump by anticoagulant to the blood gathered while blood sampling and flowing into
Blood collecting tank 110, reduces the risk that blood solidifies in gatherer process.
Fig. 3 is the connection diagram of anticoagulant tank 601 and blood sampling knife 400.From figure 3, it can be seen that anticoagulant tank 601 leads to
Crossing the first respiratory organ control valve 605 to be connected with the first respiratory organ 603, the first respiratory organ 603 stretches to anticoagulant tank by connecting leg
In 601.It is provided by the first respiratory organ 603, makes anticoagulant tank 601 will not be polluted by outside air, keep anticoagulant
Using effect.Anticoagulant tank 601 is connected with blood sampling knife 400 by peristaltic pump 602.By peristaltic pump 602 by anticoagulant tank 601
