Description
Technical field
It is a kind of blood taking bag particularly the present invention relates to a kind of medical instruments.
Background technology
Blood-letting bag is a kind of conventional hemostix, because its is with low cost, easy-to-use, and the intersection for not resulting in blood is dirty
Dye, therefore be used widely；In blood collection procedure, medical personnel often require blood sampling person periodically hold with a firm grip, diastole fist, with
Facilitate blood vessel dilatation, promote blood outflow；Because animal is different from the mankind, in blood collection procedure, animal will not coordinate medical care people
The blood sampling operation of member, therefore blood sampling speed is slower, the time spends longer, meanwhile, with the struggle of animal, blood sampling operation becomes different
It is often difficult；Also the pain of long period is caused to animal；In addition, for the low patient of internal blood pressure, such as Low women and
The elderly, VPV is slower, is also required to expend the excessive time during blood drawing, and this undoubtedly brings larger resistance to blood sampling.
The content of the invention
In view of the above-mentioned problems, the present invention provides a kind of power-assisted blood taking bag, the power-assisted blood taking bag structure is novel, unique, is protecting
On the premise of card blood sampling cleanliness factor, blood sampling speed can be effectively improved, accelerates medical procedure, reduce the pain time and the heart of sufferer
Manage pressure.
To solve the above problems, the technical solution adopted in the present invention is：This power-assisted blood taking bag includes bag, in bag
On standby pipe and heparin tube are installed, the end of heparin tube is provided with blood taking needle；
Booster is serially connected between heparin tube and blood taking needle；
The booster includes power-assisted chamber, and driving cylinder is movably set with power-assisted chamber, and the two ends of driving cylinder pass through power-assisted chamber
Cavity wall；The driving cylinder can be rotated freely around own axes, and in rotary course, driving cylinder keeps fluid-tight shape with power-assisted chamber
State；
Booster wind wheel is installed on the outer tube wall of driving cylinder；Drive rod is installed on the axis of driving cylinder, drive rod is with driving
Connected between dynamic cylinder by unilateral bearing；The foreign steamer of unilateral bearing is with driving the inner tube wall of cylinder to be fixedly connected, the lubrication groove of unilateral bearing
It is engaged through the thread with drive rod；The two ends of drive rod are fixed with limiting plate and driving plate, are set between driving plate and power-assisted chamber
It is equipped with reseting pressuring spring.
The beneficial effects of the invention are as follows：In blood sampling, after blood-taking needle blood-breaking pipe, bag and blood taking needle are fixed；Blood
Flowed through from blood taking needle after power-assisted chamber, heparin tube, into blood bag；In order to improve blood drawing efficiency, medical personnel periodically press drive
Dynamic plate so that drive rod is moved back and forth on the axis of driving cylinder；Drive rod is driven by helicitic texture, drives unilateral bearing to determine
To rotation, and then promote driving cylinder and booster wind wheel directional-rotation；Booster wind wheel rotates in power-assisted chamber, and by power-assisted intracavitary
Blood is pressed at heparin tube at blood taking needle, and then improves blood drawing speed；With the pressing of driving plate, blood can speed up stream
Go out, effectively improve blood drawing speed, shorten the blood drawing time.
In addition, during blood drawing, stirring, pretreatment of the blood by booster wind wheel, the condensation of effective anti-Hemostatic Oral Liquid, together
When can promote the initial gross separation of blood；Facility is provided for the blood treatment of next step.
To sum up, it is of the invention simple in construction, it is easy to operate, blood sampling speed can be effectively improved, shortens the blood drawing time；For
It for the crowd for being afraid of blood, can effectively shorten their frightened time and pain time, provide facility for blood sampling, also improve doctor
The operating efficiency of shield personnel.
Preferably, being provided with choking device on the heparin tube, choking device is between bag and power-assisted chamber；Needing
Blood is carried out in the case of handling in time, choking device can be used to block heparin tube, driving plate is repeatedly extruded, blood is carried out
Sufficiently stirring, processing, after preparation standards are reached, then open choking device；In addition, choking device can be additionally used in blood sampling,
The blood of bag is effectively prevented to be contaminated.
Preferably, being placed with blood group indicating ring in the outer barrel face of the driving cylinder；It is right when blood stream is through blood group indicating ring
The blood group indicating ring answered can show the blood group for conveying blood, so as to intuitively be pointed out medical personnel, prevent doctor
Shield personnel take wrong blood group.
Brief description of the drawings
Fig. 1 is the cross section structure schematic diagram of this power-assisted blood taking bag one embodiment.
Embodiment
Embodiment：
In the embodiment shown in fig. 1, this power-assisted blood taking bag includes bag 1, and standby pipe 11 and blood sampling are provided with bag 1
