Hemodialysis puncture is with nursing device

Technical Field

The invention relates to the technical field of medical instruments, in particular to a nursing device for hemodialysis puncture.

Background

Hemodialysis, one of the most common renal replacement therapies, is a process in which solutes move from a high concentration solution to a low concentration solution through a semi-permeable membrane, and involves the movement of solutes and the movement of water, that is, the blood and the dialysate are contacted with each other by a semipermeable membrane and subjected to material exchange by a concentration gradient in a dialyzer (artificial kidney), so that metabolic waste and excess electrolytes in the blood move to the dialysate, calcium ions, basic groups, etc. in the dialysate move to the blood, if the mixed liquid of albumin and urea is put into a dialyzer and the outside of the dialyzer is soaked by water, the urea in the dialyzer tube can move to the water outside the dialyzer tube through the artificial kidney membrane pores, albumin molecules are large and can not pass through the membrane pores, the phenomenon of substance movement that small molecular substances can pass through but large molecular substances cannot pass through a semipermeable membrane is called diffusion, and the method for clinically separating and purifying blood by using the diffusion phenomenon to achieve the aim of purification is the basic principle of hemodialysis.

When patient hemodialysis treatment, it is generally longer, patient probably got into the sleep state at this section of time of treatment, and the in-process of sleep still need cover the bed clothes and keep warm, and patient sleep state unconscious action can make the bed clothes drop and can touch the pjncture needle, can bring unexpected risk for patient, to the problem that exists in the current hemodialysis in-process, needs a hemodialysis nursing device for the puncture to guarantee that hemodialysis is very necessary.
