Embodiment approach 1

[0079] Embodiment 1 below applies the present inventors to a blood analyzer for analyzing a sample such as blood collected from a subject. In the blood analysis device according to Embodiment 1, measurement objects are mainly whole blood and blood preparations. The blood analysis device according to Embodiment 1 can also measure body fluids and the like as samples other than whole blood. However, for the sake of convenience, the case where the measurement objects are whole blood and blood preparations will be described below.

[0080] When the measurement object is whole blood, one whole blood mode is set from several whole blood patterns related to whole blood, and when the measurement object is blood preparation, one blood preparation measurement mode is set from several blood preparation measurement modes related to blood preparation. Whole blood is measured in the whole blood mode, and blood preparations are measured in the blood preparation measurement mode. Here, the bl...

Embodiment approach 2

[0217] Such as Figure 22 As shown in (a), in Embodiment 2, with Figure 15 In comparison with (a), step S211 is added after step S201. exist Figure 22 In step S202 of (a), the determination result of blood preparation error is also displayed according to the instruction from the operator. The configuration and other processing of the second embodiment are the same as those of the first embodiment.

[0218] Such as Figure 22 As shown in (a), in step S211, the control unit 41 based on Figure 10 The result value of the measurement item acquired in step S110, that is, the measurement result and Figure 22 (b) The judgment criteria shown in (b) judge the error of the blood preparation.

[0219] Figure 22 The determination criteria in (b) represent criteria of blood components that are satisfied by other blood preparations of different types from the target blood preparation. Figure 22 Lines 1 to 3 of (b) are criteria for judging the possibility of the three blood prepar...

Abstract

The invention provides a blood analyzer, a blood analyzing method, and a program which enable smooth testing of a blood preparation. The blood analyzer according to one or more embodiments may include: a specimen preparation part that prepares a measurement specimen by mixing a reagent into a blood preparation; a measurement part that measures the measurement specimen; a measurement mode selectionunit that receives an input of a type of blood preparation as a measurement target selected from a plurality of types of blood preparations. and a controller. The blood analyzer can be used to prepare the measurement specimen depending on the type of the received blood preparation. Thus, the operator does not have to perform cumbersome procedures such as changing setting according to the type ofblood preparation and the like in the measurement of the blood preparation, and the blood preparation can be smoothly tested.

Description

technical field [0001] The present invention relates to a blood analysis device, a blood analysis method and a program. Background technique [0002] Blood preparations refer to pharmaceuticals that contain human blood or substances obtained from human blood as active ingredients. As blood preparations, components prepared by separating components such as red blood cells, platelets, or plasma from human whole blood or human blood are known, and these component preparations are currently mainly used for blood transfusion. Ingredient preparations are used as supplementary therapy for blood components in patients undergoing various surgical operations and patients suffering from blood diseases or cancer. It is known that when the component preparation is transfused to the patient, the white blood cells of the donor remaining in the preparation can cause transfusion side effects such as fever, allergic reaction, and in severe cases, acute lung injury and other side effects of t...
