Abstract

The blood collection device for hemodialysis nursing provided by the invention effectively solves the problems that a medical worker manually shakes a blood collection tube, so that the wrist of the medical worker is painful, and bacteria are easily adsorbed on the outer wall of the blood collection tube; and the problem that an existing clamping device cannot meet the requirements of different blood collection tube specifications is solved. Comprising a collection box, a positioning plate is fixedly installed in the collection box, a plurality of swing holes are formed in the positioning plate, lifting plate rings located below the swing holes are installed in the collection box in an up-down sliding mode, and a driving belt wheel, a driving conveying belt, a soft belt, an auxiliary plate, a vertical push plate and an arc-shaped push plate are used in cooperation. According to the blood collection device, the collection tube can shake or swing back and forth, and blood in the collection tube can be prevented from being coagulated through swinging or shaking, so that the physical strength of medical staff can be saved, wrist pain is avoided, and the working efficiency of the medical staff is correspondingly improved.

Description

technical field

[0001] The invention relates to the field of medical technology, in particular to a blood collection device for hemodialysis nursing. Background technique

[0002] Hemodialysis is one of the ways of renal replacement therapy for patients with acute and chronic renal failure. It drains the blood from the body to the outside of the body, and passes through a dialyzer composed of numerous hollow fibers. It exchanges substances with the principle of convection, removes metabolic wastes in the body, maintains electrolyte and acid-base balance; at the same time, removes excess water in the body and returns the purified blood.

[0003] Blood samples should be collected from patients before and after hemodialysis to accurately evaluate the patient's Kt / V, and the correct collection of blood samples by hemodialysis centers is crucial to improve the accuracy of test results. In clinical practice, in order to avoid dialysis patients repeatedly going to the blood colle...
