Limb bracket for hemodialysis nursing

Technical Field

The invention relates to the technical field of medical assistance, in particular to a limb bracket for hemodialysis nursing.

Background

Hemodialysis (HD) is one of the alternative treatments for the kidney of patients with acute and chronic renal failure. The blood and electrolyte solution (dialysate) with similar concentration of organism are arranged inside and outside one hollow fiber by draining the blood in vivo to the outside of the body through a dialyzer consisting of a plurality of hollow fibers, and the material exchange is carried out by dispersion/convection, thereby removing the metabolic waste in the body and maintaining the balance of electrolyte and acid-base; the entire process of removing excess water from the body and returning the purified blood is called hemodialysis.

Hemodialysis treatment regimens depend on residual renal function, cardiovascular stability, protein intake, body surface area, workload, dialyzer area and dialysate properties, dialysis modality. The dialysis modes adopted by various centers at home and abroad are as follows: dialysis is carried out at the right time, and the patient has almost no uremia symptom when dialysis is started; late dialysis, which is initiated when glomerular filtration rate is <5ml/min or uremia symptoms are present; incremental dialysis refers to starting dialysis when the patient's urea clearance index (KT/V) <2.0 weekly, with increasing dialysis doses as residual renal function gradually decreases; adequate dialysis does not take into account the residual renal function of the patient and adequate dialysis treatment is initiated only if the dialysis criteria are met.

In order to improve the comfort of the patient during hemodialysis, the limb-holder is required to support the arm of the patient.

The existing body holders are mostly fixed, after positioning, the limbs of the patient are placed on the holders, and when the patient keeps a posture for a long time, the patient feels uncomfortable, but if the limbs are turned randomly, the limbs can be separated from the holders, so that a potential safety hazard exists, and therefore, the body holder for hemodialysis nursing is provided.
