what is the haemodialysis and how is the transaction done? <br />dialysis machine Dialysis is done through blood for people with kidney failure, either through a device placed in the hand and is permanent or through temporary tubes in the neck, chest or thigh called a diplon where there is the largest vein. The blood is delivered through its vessels from the device, where it connects to the human body and then returns to the device. The washing device draws blood from the artery to the device through the pressure process and then to the filter with two types of materials, a liter of lion and bio-carbonic materials with 34 liters of water, as in the pictures, where the process of Reverse osmosis is Where blood enters from the top and materials from the bottom are from areas of low concentration to centers of high concentration carried out to extract salts, toxic substances and wastes in Through a special pump in the form of a rotating lever that pushes the Blood inside a flexible tube and is connected to the line of blood return through the vein without causing damage to the blood cells. One more time This pump has an electrical and mechanical signal, the signal of the device is electrical, as it takes blood from the person to the device and then returns to the body again.. Natural washing speed 235 for blood pump. But some patients use less than 235 because this speed may cause a drop in pressure. The washing device can also measure pressure by means of a mechanical signal.<br /><br />Device control buttons:-<br /><br />1_Blood pump:-It is used to start and stop the blood pump at the specified flow rate. The button can show a light, a bright light, or no light at all.<br /><br />2_BPM:-Measures blood pressure and pulse rate<br /><br />3_Mute button:-It is used to silence the bell for different times according to the alert<br /><br />4_Ari detector alarm:-Steady light indicates air is detected in the venous drip chamber Blinking button indicates that the error has been corrected In order to reset the alarm the button must be pressed<br /><br />5_BVS:-A steady light indicates that the blood volume has fallen below the limit<br /><br />6_Attention alarm:-Steady light indicates that operator attention is required The button must be pressed for more information or instructions on the information display<br /><br />7_Technical alarm:-Blinking light indicates a technical error<br /><br />8_Fluid bypass:-It is used to manually bypass the hemodialysis fluid from the hemodialysis machine. If the button is pressed when the dialysis fluid reaches the required temperature and conduction, the button lights up when the fluid bypass button lights up for 5 minutes during treatment, an alert alarm will be activated.<br /><br />9_Blood leak:-Solid light indicates blood is detected in the dialysis fluid after the dialysis machine Luminous button indicates that the error has been corrected To reset the alarm the button must be pressed
