dialysis machine is often used when the kidneys fail to work properly.
The kidneys can be thought of as organic machines
waste products, including urea and excess water from the
blood through a process of filtration.
The filtered waste and
excess water are then converted into urine and ultimately pass out of
the body through urination.
the kidneys are waste removal organs and when they stop functioning
in a proper way, toxic metabolic wastes build up. Many circumstances
cause impaired renal function, including acute or chronic disease and
trauma. Severe problems of health can arise when kidney function is
Severe cases of renal failure can cause death unless renal replacement
therapy is utilized to sustain life. The two options are a kidney
transplant or a process by which the blood is artificially cleansed,
mimicking some of the lost kidney function. The latter, called
dialysis, is usually performed by a dialysis machine.
Dialysis is a medical therapy which can take two major forms:
hemodialysis and peritoneal dialysis.
hemodialysis machine removes blood from the patient's body through a
set of tubes and then uses a semi-porous, membrane filter enclosed
within a canister (called a dialyzer) to act as an artificial kidney
and cleanse the blood of wastes along with excess salts and water. A
sterile solution consisting of water, sugars and other substances is
inside the dialyzer, surrounding the membrane filter. Several important
blood components, including red and white blood cells, are too large to
pass through the membrane's pores and are not filtered out of the
blood, but salts, urea and other wastes flow through the membranes into
the sterile solution and are ultimately removed from the machine.
Hemodialysis is typically done around 2 or 3 times per week at
dialysis center or clinic. Each in-clinic
treatment usually takes approximately three to four hours.
hemodialysis is an alternative to in-clinic treatment and is growing in
popularity. The patient is taught how to perform the treatments at a
dialysis center. Home hemodialysis also uses a dialysis machine.
Typically, home dialysis is done five to seven days per week, with each
treatment taking approximately two to three hours. It can even be done
overnight while the patient is sleeping.
Peritoneal dialysis is
a different type of process, although it serves the same purpose:
mimicking some of the functions of the kidneys. In this type of
procedure, dialysis solution is dripped directly into the patient's
abdomen. Waste products in the patient's blood enter the fluid, which
is drained out in a few hours after it has become almost saturated with
The continuous ambulatory peritoneal dialysis equipment (a CAPD device)
allows the patient to move around. Alternatively, continuous cycling
peritoneal dialysis (CCPD) is often done overnight. This technique uses
a machine that drains and refills the abdomen with dialysis solution
price of the machines typically ranges from 300 (used) to 6,000 dollars.
Dialysis machines can be life-saving, although
the dialysis procedure is not without its burdens, being time-consuming
and often requiring regular trips to a dialysis center. The development
of dialysis machines that allow self-treatment at home eases the
