Automatic arm binding strap control device for venous blood sampling

Abstract

The invention provides an automatic arm binding strap control device for venous blood sampling. The automatic arm binding strap control device for venous blood sampling comprises an operating box installed on a movable supporting leg frame. A movable seat for seating a blood sampling operator and a movable seat for seating a person with blood to be sampled are arranged at the rear end and the front end of a box bottom plate of the operating box respectively. The person with blood to be sampled is seated on the corresponding movable seat and places one arm in an elastic binding strap of a tensioning controller from one side of the semicircular box wall of the operating box, wherein the elastic binding strap stretches out from a binding strap slit in the upper side of an operating platform; a computer controller is arranged at the rear end of the operating box and controls a transmission controller to drive the tensioning controller through a data line, and the elastic binding strap where the arm of the person with blood to be sampled is placed is automatically tensioned to a suitable tightness degree, so that venous blood is prevented from flowing back, the vein of the arm of the person with blood to be sampled is exposed, and then blood sampling is completed. The automatic arm binding strap control device has the advantages that the arm binding strap control device with the automatic detection and tightness degree control functions is developed, batched blood sampling is conveniently, rapidly and safely completed, and problems existing in blood sampling are solved.

Description

technical field [0001] The invention relates to an automatic arm tie control device for venous blood collection. Background technique [0002] At present, when the hospital collects blood from the veins of the blood recipient's arm, it generally adopts manual blood collection. The blood collector chooses the median vein of the elbow of the blood collector, first tie a tourniquet, and choose a thick, straight, and elastic vein. Then loosen the tourniquet; for the binding of the tourniquet, the manual operation is slow and inefficient, and the degree of tightness of the tourniquet is not good when encountering the elderly, children, fat people, thin people, and people with inconspicuous blood vessels Therefore, it is more difficult to collect blood, especially when encountering a large number of physical examinations, it will affect the speed even more, and cannot adapt to the requirements of large-scale blood collection in hospitals. In order to overcome the above difficultie...
