Patent ID: 8163564

Claim:
A computer connected to a blood analyzer configured for analyzing a blood sample and outputting an analysis result to the computer and a smear preparing apparatus configured for preparing a smear of a blood sample on a slide glass based on a smear control parameter, the computer comprising: a communicator configured for communicating with the blood analyzer and the smear preparing apparatus; a condition setter configured for setting a smear level value for identifying the smear control parameter and a value range of a count of a first blood cell, the smear level value corresponding to the value range and to the smear control parameter; a memory; and a controller programmed to carry out operations comprising: receiving a setting of the smear level value and the value range by the condition setter; storing the received smear level value and the received value range in correspondence with each other in the memory; receiving, from the blood analyzer via the communicator, an analysis result comprising a count of the first blood cell and a hematocrit value of the blood sample, wherein the count of the first blood cell of the blood sample is at least one of a white or red blood cell count; generating, when the count of the first blood cell of the blood sample is within the value range stored in the memory, a first instruction that causes the smear preparing apparatus to prepare a smear of the blood sample according to a first smear control parameter corresponding to the smear level value, the first instruction comprising the smear level value stored in the memory; transmitting, when the first instruction has been generated, the first instruction to the smear preparing apparatus via the communicator; generating, when the count of the first blood cell of the sample is not within the value range stored in the memory, a second instruction that causes the smear preparing apparatus to prepare a smear of the blood sample according to a second smear control parameter corresponding to the hematocrit value of the blood sample, the second instruction comprising the hematocrit value of the blood sample; and transmitting, when the second instruction has been generated, the second instruction to the smear preparing apparatus via the communicator; wherein the computer and the smear preparing apparatus are disposed at different locations, and wherein the smear preparing apparatus is configured to: determine, when the first instruction is received, the first smear control parameter corresponding to the received smear level value and prepare a smear of the blood sample based on the first smear control parameter; and determine, when the second instruction is received, the second smear control parameter corresponding to the received hematocrit value and prepare a smear of the blood sample based on the second smear control parameter.
