design and construct of an anti hemorrhage device for the dialysis patients needling after hemodialysis

needling is one of the challenges that dialysis patients are facing with, for which selection of an appropriate method and speed of work is of high importance. at the end of dialysis process, when nurse begins withdrawal of the needle, she/he has to be careful so that the blood vessel in puncture site may not bleed. the work has to be done with speed and care. correct performance of the procedure is of great help to patients, and also nurses working in dialysis ward. this may result in feasible stoppage of bleeding, and prevention of probable infections. the study aims at design and manufacture of a device to stop bleeding after withdrawal of needle from hand of dialysis patients, after the end of hemodialysis process. as you may know, after needle removal, the injection site has to be pressed for a certain time period (about 15 minutes) with a pressure more than blood pressure inside the vessel so that bleeding would be stopped, and not continued upon removal of pad. the process is currently done by patients themselves, persons accompanying them, or nurses. to make the process mechanized, we are intended to make a device. this way, time and quality of the procedure will be improved; and, safety against infection probability would be assured. in introduction section, an overview of the research importance and history has been made. in the research method section, an introduction has been made to the method applied, and its advantages. eventually, analytical results have been discussed in conclusion section, in details.
