摘要： An extracorporeal blood circuit is disclosed for withdrawing, filtering and returning blood from peripheral blood vessels. The blood passage in the circuit extends through a withdrawal tube connected to a catheter in a peripheral vein, a filter, one or more pressure sensors and return tube also connected to a catheter in a peripheral vein (which may or may not be the same vein as used for the withdrawal tube). The blood passage is air free, and has smooth passage walls which promoted continuous and uniform flow of the blood through the circuit.

摘要： A method and apparatus for ultrafiltration of blood operating by removing blood from a peripheral blood vessel at a rate of less than two percent of total cardiac output of a patient, extracting fluid at a rate of 0.1 liter to 1.0 liters per hour while retaining cells and proteins in the blood, and returning the concentrated blood to a secondary blood vessel is disclosed. Blood is removed and returned using small gage needles. As a pump circulates blood from the patient, a filter removes ultrafiltrate from the blood using duty cycle or pump control, and a transparent container collects the removed fluid.

摘要： Catheters used for medical treatment, e.g., hemodialysis are filled with a locking solution, usually heparin between treatments. To prevent infections, antimicrobial or antibiotic substances have been used as locking solution alone or in combination with antithrombotic substances. It has been found that these locking solutions are rapidly washed out from the catheter tip. The invention describes a thixotropic gel that can be used as locking solution. Beneficial substances, e.g., antimicrobial or antibiotic substances can be added to the gel. A preferred antimicrobial substance is taurolidin alone or in combination with salicylic acid or one of its salts.
