Abstract: PROBLEM TO BE SOLVED: To provide a specimen analyzing apparatus which can accurately estimate an amount of serum even when a hemoglobin is hemolyzed in the serum or a fibrin is mixed in the serum and to provide a method for estimating the amount of the serum. SOLUTION: A serum estimating apparatus 1 detects a transmitted light transmitted through a blood collecting tube 100 by a line sensor 12 opposed to an infrared ray surface source 11 via the tube 100 when the tube 100 in which a bar code label 200 is adhered, is irradiated with an infrared ray from the surface source 11. The estimating apparatus 1 forms a profile of an intensity of the transmitted ray based on a detected result of the sensor 12, specifies a position of an interface between an upper liquid surface of a serum layer of a blood specimen contained in the tube 100 and a separate layer based on a differentiated value obtained by linearly differentiating the profile, and estimates the amount of the serum housed in the tube 100 based on their positions and a shape of the tube 10.

Abstract: PROBLEM TO BE SOLVED: To operate the absorbance of a sample in a container accurately by receiving a light transmitted through the container, determining the intensity characteristics of transmitted light along the axial direction of the container and the direction perpendicular thereto and then determining the intensity of transmitted light in the center of the container based on the intensity characteristics of transmitted light. SOLUTION: A container 10 is positioned between a light emitting section 14 and a light receiving section 16 using a handier and then the intensity characteristics of transmitted light is determined along the axial direction of the container and the direction perpendicular thereto and stored in a memory 32 at a data processing section 30. The intensity characteristics are compared with a predetermined threshold value and the opposite ends of the container 10 are located thus determining the outline thereof. Subsequently, the center of the container 10 is specified and the intensity of transmitted light in the center is specified in order to calculate the absorbance according to the Lambert's law. According to the method, absorbance of a sample in the container 10 can be measured accurately without requiring any transfer of the sample or troublesome positioning of the container 10.

Abstract: PROBLEM TO BE SOLVED: To obtain a dispensing apparatus whose structure is not made complicated when a level is to be detected by using ultrasonic waves, in which ultrasonic wave power is narrowed down to an object to be inspected and which excludes the influence of an external noise. SOLUTION: A nozzle 10 is constituted of a nozzle base part 12 and of a nozzle tip 14, and an ultrasonic sensor 18 is installed at the nozzle base part 12. The nozzle 10 is lowered, and a sample is cucked up. Then, at a point of time when the sample is sucked up into the tip of the nozzle 10, a change appears in a reception signal. A level inside a container 20 is detected on the basis of the change. In addition, when a change in the reception signal due to the blockade of the tip opening of the nozzle is detected, the level is detected.

Abstract: PURPOSE:To detect residual liquid adhering to a nozzle cleaned after sucking a sample. CONSTITUTION:A nozzle part 10, which is double pipe nozzle, is inserted into a well 204, and air of the fixed flow rate is supplied to the inside of an inner nozzle 14. In this process, an air pressure inside the piping is detected to be compared with the residual liquid determining threshold value. If the air pressure exceeds the threshold value, it is determined that residual liquid 106 exists in the inside or in the outside of the inner nozzle 14.

Abstract: PURPOSE:To prevent a nozzle for sampling from coming into direct contact with a rubber stopper when the nozzle is pierced into the rubber stopper and a sample at the inside of a sample tube is sampled. CONSTITUTION:A nozzle part 10 is constituted of an inner nozzle 14 and an outer nozzle 12. The nozzle part is pierced into a rubber stopper in a state that the inner nozzle 14 has been housed inside the outer nozzle 12. After the nozzle part has been pierced, the tip part of the inner nozzle 14 is lowered from the tip opening of the outer nozzle 12, and a sample is sampled. After the sample has been sampled, the nozzle part is cleaned by utilizing a cleaning tank.

Abstract: PROBLEM TO BE SOLVED: To provide a specimen analyzing apparatus which can estimate the amount of serum accurately even in the case a bar code label is attached to a specimen vessel, or hemoglobin or bilirubin is merged or mixed into the serum. SOLUTION: In the apparatus 1 for estimating the amount of the serum, infra-red light is emitted from a surface emitting infra-red light source 11 and projected onto a blood sampling tube 100 on which the bar code label 200 is attached, and light transmitted through the blood sampling tube 100 is detected by a line sensor 12 being arranged opposite to the surface emitting infra-red light source 11 through the blood sampling tube 100. The apparatus 1 for estimating the amount of the serum identifies a position of the interface between a separated layer and the upper level of the serum layers in blood specimen contained in the blood sampling tube 100 on the basis of the detected result of the line sensor 12, and estimates the amount of the serum contained in the blood sampling tube 100 on the basis of the identified position and the shape of the blood sampling tube 100.

Abstract: PROBLEM TO BE SOLVED: To provide a specimen analyzer for rapidly and surely reading an information bearing label attached on a specimen container by a specimen analyzer or a device disposed on its downstream side.
SOLUTION: Based on positional information on a bar-code label 200 on an outer circumferential surface of a blood collection tube 100 detected by a glossiness sensor 14, a blood serum amount estimation device 1 adjusts the rotating position of the collection tube 100 by actuating a manipulator rotating mechanism 22 so as to cause the label 200 to face on a bar-code reader 13 and then reads the label 200. After optical detection is performed to analyze a blood specimen housed in the collection tube 100, the rotating position of the collection tube 100 is adjusted so to direct the label 200 in a prescribed direction and the collection tube 100 is returned to a blood collection tube rack 600. A plurality of blood collection tubes 100 on the rack 600 are sequentially treated and the directions of the labels 200 are aligned.
