Portable uremia patient hemodialysis machineTechnical Field
The invention relates to the technical field of medical instruments, in particular to a portable hemodialysis machine for uremia patients.
Background
Hemodialysis (Hemodialysis), called Hemodialysis for short, is also called artificial kidney and kidney washing in popular terms, and is one of the blood purification technologies. The semi-permeable membrane is used for achieving the purpose of purifying blood by diffusing and removing various harmful and redundant metabolic wastes and excessive electrolytes in human bodies out of the body, and achieving the purpose of correcting water electrolyte and acid-base balance by absorbing, wherein the clinical meaning is that some wastes in the blood are removed through the semi-permeable membrane. Hemodialysis is one of the safer, easy-to-use and widely-applied blood purification methods. Dialysis refers to the movement of solutes from a highly concentrated solution to a less concentrated solution through a semi-permeable membrane. Hemodialysis involves the movement of solutes and the movement of water, i.e., the exchange of substances between blood and dialysate in a dialyzer (artificial kidney) by means of semipermeable membrane contact and concentration gradients, causing metabolic wastes and excess electrolytes in the blood to move towards the dialysate, and calcium ions, bases, etc. in the dialysate to move towards 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, and albumin molecules are large and cannot pass through the membrane pores. The phenomenon of substance movement in which small molecular substances can pass through but large molecular substances cannot pass through a semipermeable membrane is called diffusion. The basic principle of hemodialysis is the method of clinically separating and purifying blood by diffusion phenomenon to achieve the purpose of purification.
At present, the existing hemodialysis machine has a large appearance, so that doctors are not easy to carry to treat the hemodialysis machine, the hemodialysis machine in a hospital is too complicated and is not easy to clean, and the flow rate of blood during hemodialysis cannot be adjusted according to the real-time blood pressure of patients.
