摘要： A test strip automatic supply device has: a cylindrical container 11 provided with a slit 15 which is formed in a side wall thereof so as to contain an elongate test strip; a container supporting table having, in an upper portion thereof, a semi-cylindrical concave surface provided with an opening 20 which is formed in a middle portion of the concave surface so as to allow a test strip fitted in the slit of the container 11 to fall through and be taken out; and a carrying stage 31 which receives and transports a test strip falling from the slit 15. While the transporting stage 31 is transporting a test strip, optical means finds whether the test strip is faced up or down. The device has such a function that side reversing mechanism flips it over during transportation if it is face down. An operator only has to put test strips in the container. The tests strips are automatically let out of hte container one at a time.

摘要： PURPOSE:To enable automatic supply of a test piece smoothly by fitting the test piece into a through groove of a container during a reciprocal rotation of a cylindrical container to position the test piece at an external takeoff position when a rotary motion is stopped. CONSTITUTION:A cylindrical container 11 is rotated in reciprocation several times to fit one sheet of a number of test pieces loaded inside into a through groove 15. Then, with the through groove 15 matching a hole 20 of a container support base 18, a shutter 45 is pushed downward to open the hole 20 so that the test piece is lowered onto a conveying stage 31 and the stage 31 is moved to the left (retraction) to let the test piece drop into a test piece receiving groove 38 to fit. All the test pieces are turned upward in surface moving the stage 31 to the right (advance) to be positioned at an external takeoff position. At this point, the shutter 45 returns to the position of the hole 20 and the test pieces left are pushed back into the container 11 with a solenoid 46. The hole 20 is closed. The test pieces positioned at the external takeoff position are emmersed into a sample of a sample container with a test piece holding/ conveying device.

摘要： PURPOSE:To prevent the generation of electrical noises and to improve the maintenance characteristic of the reference electrode provided to an electrolytic measuring instrument attached to an automatic blood analysis apparatus by insulating the internal standard soln. flowing in the electrode and deaerating the soln. CONSTITUTION:The internal standard soln. 24 which is the electrolytic sample soln. fed from a syringe is put through the inside of a tube 25 into an insulating trap 26 where the standard soln. 24 is insulated and the air bubbles generated by the dissolved oxygen in the standard soln. 24 are removed in the tube 24. Only the deaerated standard soln. 24 is fed via a tube 27 into a hole 28 of an outside cylinder of the reference electrode 20 made of glass. The hole 28 is previously formed to the same bore as the bore of the tube 27 so that the remaining air bubbles do not stagnate therein. Ceramics 29 having many holes is mounted to the mid-point of the hole 28 so as to face a horizontal direction and the reference electrode 31 contg. potassium bromide as the internal soln. 30 is mounted thereto. The internal electrode 32 is immersed in the soln. 30. The reference electrode 20 which is not affected by the air bubbles is obtd. in such a manner.

摘要： In an automatic analyzing apparatus for analyzing multi-analysis items in regard to biological samples, a reaction disk, on which a lot of reaction containers are arranged, is repeated to be rotated by one rotation plus one pitch and stopped for receiving a reagent, and intermediately pauses twice between the stops without delivering reagents. The apparatus is so set that a third reagent for the latest delivery timing is delivered during a stop for receiving a sample at a single reagent delivering position E, and a first and a second reagent are delivered during the intermediate pauses at the single reagent delivering position E. After delivering a sample to a specified reaction container, the reaction container is delivered with the first reagent during an intermediate pause in a first cycle and the second reagent during an intermediate pause in a some cycle after the delivery of the first reagent, and then the third reagent during a stop for receiving a sample in a some cycle after the delivery of the second reagent.

摘要： A sample container (20) containing a urine sample (22) is transferred by a sample positioning device to a liquid level sensing position. At this sensing position, the liquid level in the sample container is detected by a level sensor (39), followed by transfer of the sample container to a dipping position. A liquid level rising member (40) is then inserted to the sample container. While being held by a handling device, a test strip (23) is dipped into the sample in the sample container with the liquid level raised. Thereafter, the test strip (23) is lifted out of the sample container (20) and transferred to a measuring device. Color development in reagent sections on the test strip is measured by a photometer in terms of the reflected light strength. With the present invention, analysis using test strips can be implemented even when the sample volume sampled into the sample container is small.

摘要： A slide specimen extracted from a cassette at a receiving position is carried to a holding position for waiting by a carrier along a carrying pass. While at the holding position, a previously inspected specimen that has been observed through a microscope is placed on the carrying pass at a specimen replacing position. Thereafter the specimen that has been held at the holding position is carried to the replacing position by the carrier, while at the same time the specimen that has just been placed at the replacing position is moved along the carrying pass by the carrier. The specimen then placed in the replacing position is picked up by a pair of holding arms and carried to an observing position of the microscope. The specimen is retained by vacuum adsorption and by specimen retainers which resiliently hold it by means of springs in contact with the vacuum adsorption surface. In the meantime, the specimen that has already been observed and shifted toward the specimen feeder is moved the rest of the way to the specimen feeder and replaced into the original cassette from which it was extracted. After replacing the specimen, a new specimen is extracted and carried to the holding position as the process is repeated until all of the slide specimens have been observed.
