Disclosed is a solid-type ion sensor which does not have an internal liquid chamber. The ion sensor has a laminated structure basically includes an electrically conductive substrate, a redox layer having a redox function covering the surface of the electrically conductive substrate, and an ion-selective layer covering the surface of the redox layer. Also provided is an ion sensor of this type having an insulated thermister imbedded so as to contact the redox layer.

Bacteria can be isolated from blood by mixing blood to be examined with a liquid containing a hemolytic reagent and an anticoagulant. The resultant mixture is filtered through a filter having a pore size that does not allow passage therethrough of the bacteria to be separated. Nutrients are then supplied to the bacteria on the filterthrough the mixture so as to immediately culture the bacteria on the filter.
摘要:
A polymer solution [5] is caused to flow and spread in a uniform thicknesss on a substrate [2], where upon the formed layer of the polymer solution is solidified in a bad solvent [6], this method comprising the use of a fluorinated hydrocarbon [6] as the bad solvent and, optionally, carrying out the removal of a good solvent mingling into the fluorinated hydrocarbon [6] during the course of the solidification by the technique of extraction [12] with water, and recycling the fluorinated hydrocarbon.
摘要:
In a membrane type artificial lung using as gas-exchange membranes porous hydrophobic membranes having a wall thickness in the range of 5 to 80 µm, a porosity in the range of 20 to 80%, and a pore diameter in the range of 0.0l to 5 µm, the minute pores 3 of the membranes 2 are blocked with minute particles 4 having a diameter smaller than the pore diameter and having a hydrophobic surface at least on the sides thereof intended for exposure to blood. Optionally, the gas-exchange membranes have the surface for exposure to blood coated with a biocompatible hydrophobic resin.
摘要:
A flowmeter has a main body (8) having fluid inlet and outlet passages (7a, 9a) and a vertical fluid channel (11) formed in the main body (8) and having one end communicating with the inlet passage (7a) and the other end communicating with the outlet passage (9a). The vertical fluid channel (11) has a first passage (11a) and a second passage (11c) having a cross-sectional area larger than that of the first passage (11a). The first passage (11 a) has therein a float (14) for regulating a flow rate of the fluid flowing therethrough, and is tapered to have a cross-sectional area increasing from the inlet passage side toward the outlet passage side such that the float (14) remains in position when the fluid passes through the first passage (11a). The second passage (11c) has therein a valve (17) for opening the second passage (11c) when the fluid is to flow therethrough and for closing the second passage (11c) when the fluid is not to flowtherethrough. The valve (17) has a projection (17b) for moving the float (14) toward the inlet passage (7a) when the second passage (1 lc) is closed. The float (14) and the valve (17) have specific gravities larger or smaller than that of the fluid.

@ For the treatment of various diseases including autoimmune diseases such as myathenia gravis, articular rheumatism, lupus erythematosus, etc., immunity-related diseases such as glumerulonephritis, bronchial asthma, polyneuritis, etc., organ transplantation such as transplanted kidney rejection, AOB incompatibibity bone marrow transplantation, etc., tumor, hypertension, and hepatic insufficiency, immunoglobulin adsorbents comprising a hydroxyl-containing water-insoluble carrier to which a diamine compound having the general formula: wherein n is an integer having a value of 3 to 9 is attached through a silane coupling agent or a derivative thereof, to which diamine a heterocyclic compound is attached through a difunctional reagent, are useful as they can selectively and efficiently adsorb specific proteins such as immunoglobulins and immune complexes which are pathogenic substances in the diseases, exhibit minimized non-specific adsorption, and are safe and easy to sterilize.
摘要:
An apparatus for measuring cardiac output includes a first system for obtaining cardiac output based on a thermal attenuation method and a second system for obtaining blood flow velocity based on a thermal-type flowrate measurement. A constituent value is obtained from the cardiac output and blood flow velocity, and the constituent value is held. The apparatus also includes a computing unit for computing cardiac output from the already obtained constituent value and a blood flow velocity obtained at the time of measurement. The constituent value can be updated by starting the first system.
摘要:
A medical instrument having a path for receiving a bar-like member and a combination of valves (16, 17) provided in the path. The combination of valves (16, 17) comprises a first disc-like valve (16) having a first slit (18) open only to one of the end faces thereof and a second slit (19) open only to the other of the end faces thereof, the first and second slits (18, 19) crossing each other to form a distance of intersection inside the first valve (16), and a second disc-like valve (17) disposed in parallel to the first valve (16) and having a slit (21) opening to both end faces thereof. The slit (21) of the second valve (17) crosses the intersection point of the first valve (16) so that the bar-like member passes through the slit (21) of the second valve (17) as well as the intersection of the first valve (16) when it is inserted.
摘要:
A drug administering apparatus includes a container (11) with body fluid inlet and outlet ports (11a, 11b) which communicate with each other, and a liposome agent (32) entrapping a drug therein. An insoluble substance (31) is fixed inside the container (11) and has the liposome agent (32) such that the liposome (32) agent can be brought into contact with the body fluid flowing in the container (11). The drug entrapped in the liposome (32) is released into the body fluid flowing in the container (11).
