Description

[Detailed Description of the Invention] <Technical Field> This invention records cells that cannot be classified into predetermined types of cells by an automatic cell analyzer as unknown cells on a videotape, and The present invention relates to an apparatus for reproducing recorded images of unknown cells that efficiently reproduces images during determination work.

<Prior Art and its Problems> As is well known, an automatic cell analyzer is used to classify specimens such as blood into various types of cells, but there are cases in which cells that cannot be classified are generated. Therefore, these unknown cells that could not be determined were recorded on a videotape, and a laboratory technician later viewed the videotape to determine the unknown cells.

By the way, conventionally, when determining these unknown cells,
The laboratory technician plays the videotape frame by frame,
In other words, the method used was to play back the image of one unknown cell and make a determination, and then play back the image of the next unknown cell, which required a playback operation each time, and the machine operation was troublesome. At the same time, there was a problem that the judgment speed was slow.

Also, as mentioned above, playback starts frame by frame,
Since the regeneration is stopped, there is a problem that the life of the mechanical system of the regeneration device is shortened.

<Object of the invention> This invention was made in view of the above problems.
When playing a recorded videotape of unknown cells to determine the type of cell, the videotape can be played back efficiently to simplify operations during the determination process and shorten the time required for determination. The purpose of the present invention is to provide a recorded image playback device.

<Structure and Effects of the Invention> The present invention is for playing back a videotape in which sample data including at least the number of unknown cells of each specimen and unknown cells are recorded for each specimen, and a playback device for playing the videotape; , a monitor that displays a recorded image based on a playback signal, a determination input key for inputting the type of cell when the unknown cell is determined based on observation of the monitor image, and a stop and start of playback of the playback device. and a playback control device that determines the recording end position for each sample based on the playback signal and instructs the playback device to stop playback when the videotape reaches the recording end position. recording end determining means for outputting a stop signal; storage means for reading and storing the number of unknown cells in the specimen from the playback signal; counting means for counting the number of operations of the determination input key; and the number of unknown cells and the operation. and regeneration start determination means for determining whether or not the number of times are equal, and outputting a regeneration start signal instructing the regeneration device to start regeneration when it is determined that they are equal, and all determination inputs for unknown cells in one sample are completed. After that, the next specimen is reproduced.

According to this configuration, when a videotape recording unknown cells is played back and the type of unknown cells is determined from this recorded image, the recorded videotape is played back for each specimen, and at the recording end position of each specimen. is stopped once, and the next sample is played after all judgment inputs have been made.

Therefore, the frequency of starting and stopping the playback device is significantly reduced compared to a configuration in which the unknown cell image of the specimen is played back in a frame-by-frame manner and then stopped, during which unknown cell determination input is performed. Therefore, the life of the playback device can be extended for a long time.

In addition, since unknown cell images are continuously reproduced for each sample, compared to frames that are reproduced frame by frame, laboratory technicians can perform the task of determining unknown cells in a shorter time, and they can always use stable images. You can do the judgment work without straining your eyes.

<Description of Embodiment> An embodiment of the present invention will be described below based on the drawings.

When the next image is data B related to specimen b, a signal “1” is recorded in the signal recording unit 4 corresponding to Nothing is recorded in the recording section 4.

An embodiment of the apparatus for reproducing recorded images of unknown cells that reproduces video tapes recorded as described above will be described with reference to FIG.

6 is a playback device that plays back the videotape 1 at a constant speed; 7 is an operation start instructing device such as a key switch for instructing the playback device 6 and the computer 10 to start operation; 8 is a television that displays the reproduced unknown cell image. Monitor 9 is a determination input key for inputting the type of cell when it is determined that it is an unknown cell.

The computer 10 has a function of reading and storing data regarding the reproduced specimen, and from the data, at least the number of unknown cells of the specimen is stored, as well as an identification signal of the specimen, and an intermediate cell analysis device for the specimen. If analysis results are recorded, these contents are also stored. Furthermore, there is a function of counting the number of operations of the judgment input key 9, and determining whether or not the number of operations is equal to the stored number of unknown cells, and when it is determined that they are equal, instructing the reproducing device 6 to start reproducing. It has the function of giving commands, etc.

11 is a specimen identification signal stored in a display device;
Interim analysis results are displayed. Reference numeral 12 denotes a signal discrimination circuit that reads the signals stored in the signal storage section 4 of the audio track 3 of the video tape 1 and stops the playback by the playback device 6 at a position before the recording position of the next sample. 13 is the computer 10 when the judgment input of all unknown cells regarding one specimen is completed.
This is a tape puncher for tape punching the final analysis results for one specimen. In this embodiment, a computer 10 and a signal discrimination circuit 12 constitute a reproduction control device 14.

The operation of the apparatus for reproducing recorded images of unknown cells constructed as described above will be explained based on FIGS. 1 to 3. FIG. 3 is a flowchart showing the operation of this device.

A videotape 1 recording data regarding the specimen and unknown cells of the specimen is set in the playback device 6,
When the operation start instruction device 7 is operated, the playback device 6 starts the playback operation and plays back the video tape 1 at a constant speed. At the same time, the computer 10 constituting the playback control device 14 also starts operating.

The playback operation of the playback device 6 is performed by the signal discrimination circuit 12 regardless of whether or not the test technician operates the unknown cell determination input key 9. 4
The playback is continued until the signal "1" recorded at the bottom of the third unknown cell image is detected, and when the signal "1" is detected, the playback device 6 stops.

During this time, data A related to specimen a shown in FIG. 1 and a plurality of unknown cell images are continuously displayed on the television monitor 8 by the above-mentioned reproduction operation.

On the other hand, when the operation start instructing device 7 operates (ST10), the computer 10 reads the number of unknown cells of the specimen a from the reproduction signal of the reproduction device 6 and stores it (ST11), and also stores other data such as the identification symbol and intermediate value of the specimen a.
