To achieve the above object, the technical solution of the present invention is to provide a kind of automatic arm band control dresses of venous blood collection
It sets, the polyhedron-shaped operation cabinet being mounted on foot-supporting frame living including one, operation cabinet two sides are parallel side box walls,
Operate cabinet is bottom plate below, on the bottom plate of operation box back and on the bottom plate of operation cabinet front end
It is separately installed with the sliding seat taken for blood sampling operator and the sliding seat for being taken by blood sampling people, operates the top of cabinet
It is operating platform, can be convenient in the semicircle tank wall of operation cabinet front end and arm is put into before operating platform by blood sampling people
In the elastic band of the tension controller stretched out in the band slit on side, there is an arm bracket that can fix on operating platform and put
Enter for by blood sampling human arm and start its top induction start switch, in conjunction with close to operation box back have computer controller
Controller is tensed by the drive controller driving that data line traffic control is mounted on operation box house, will have been placed in and be adopted automatically
The elastic band of blood human arm is tightened to suitable tightness, to prevent venous backflow in order to expose and taken a blood sample
The vein blood vessel of human arm, it is convenient to carry out blood sampling operation in next step.
The beneficial effects of the present invention are: developing one kind does not use traditional artificial Nannal bundling tourniquet, it is automatic accurate
Complete the automatic arm band of venous blood collection control device, overcome tied up in venous blood collection tourniquet tightness it is bad
It grasps, so that influencing the problem of the speed of blood sampling will be had been placed in automatically using Automatic Detection and Control technology by blood sampling human arm
Elastic band be tightened to suitable tightness, to prevent venous backflow and expose by the vein of blood sampling human arm
Blood vessel completes blood sampling operation, fundamentally solves the carry out vein of hospital's high-volume, convenient, fast, automatic, safety, standard
The problem of automatic arm band of taking a blood sample works.
