摘要:
This invention is a switch bag type blood-gathering set (1) used for transfusing blood gathered from a blood donor to the same blood donor again, and for newly gathering predetermined amount of blood from the blood donor. This switch bag type blood-gathering set (1) comprises a liquid transferring member (2) for introducing a physiological saline solution into the blood-gathering set (1), a blood transfusing member (3a,3b) for introducing blood from a blood bag into the blood-gathering set (1), a blood-transfusing and gathering member (4) for supplying blood to or gathering blood from the donor, a washing solution storing member (6) for containing a waste liquor after priming in the blood-gathering set (1), and a blood storing member (5a,5b) for storing blood gathered from the donor, and these constituents are connected by connecting tubes (9,13a...42,43) so as to not contact with the air outside.

A liquid dripping control device holds a flexible tube (4) between a stationary clamping jaw (7) and a movable clamping jaw (11), and adjusts the amount of throttling of the tube by the movable clamping jaw (11), and comprises means (6a, 6b) for detecting dripping of a liquid staying in a dropping tube (5) connected to said flexible tube (4); means (10, 12, 14) for moving at high speed the movable clamping jaw (11) to a direction of opening said flexible tube so as to rapidly start dripping of the liquid staying in the dripping tube; a means for, after detecting start of the liquid dripping, moving the movable clamping jaw (11) in a direction of throttling the flexible tube and stopping it; and a means for, after detecting subsequent dripping, moving the movable clamping jaw (11) at low speed so as to control said subsequent dripping at a predetermined speed.

A humors processing device is such as an artificial kidney, artificial liver or others. The device is connected with a humors circulating line which is provided with bags supporting physiological saline solution and with communicating mechanisms at appropriate portions of the same, and the communicating mechanism is ready for opening by finger pressure.

A line for use in body fluid treatment comprises a tubular body fluid passageway member at least part of which is made of a flexible material, an outer tubular member which is made of a nonflexible material and contains said tubular body fluid passageway member hermetically enclosed therein, a pressure detecting member for monitoring the pressure of the flowing body fluid by means of a fluid filled in the hermetically closed space between the outside surface of said tubular body fluid passageway member and said outer tubular member without substantial contact of the body fluid with air, and a body fluid filtering member comprising a filter. The line is especially useful as a blood line for non-anticoagulant hemodialysis.
摘要:
A blood treatment apparatus realizing double-step-membrane filtration, namely separation of blood into plasma and a corpuscular fraction in a first membrane module 4 and separation of highmolecular-weight substances (e.g. y-globulin) in the plasma from low-molecular-weight substances (e.g. albumin) in a second membrane module 10 comprises a blood inlet circuit including a pump M 1 (1) connected to the first module 4 a plasma outlet circuit 9. which includes a pump M 2 (7) and that conveys plasma from module 4 to module 10, which has a plasma fraction outlet circuit 14 (including a pump M 3 (12)) for the high-molecular weight fraction removed in module 10, and a blood return circuit 15. which links up with a corpuscles outlet circuit 18 from module 4 to return purified blood to the patient. the flow rate ratio between pumps M 2 (7) and M 3 (12) being controllable so as to give a desired ratio of input to output of module 10, the plasma pressure being also controllable so that it is never substantially negative. The apparatus is effective, e.g. in the treatment of blood of patients with peripheral circulatory insufficiency due to arteriosclerosis and of patients with rheumatoid arthritis, which is an autoimmune disease
