Abstract

Disclosed is a washing method for a staining bath in a smear sample preparing apparatus. The staining bath is able to accommodate a glass slide having a specimen smeared thereon, and stores therein a staining liquid for staining the specimen smeared on the glass slide to perform a staining process. The washing method includes: receiving information related to a washing condition; and executing a washing operation for the staining bath, according to the received information.

First claim

What is claimed is:

1. A washing method for a staining bath in a smear sample preparing apparatus, the staining bath being able to accommodate a glass slide having a specimen smeared thereon, the staining bath being able to store therein a staining liquid for staining the specimen smeared on the glass slide to perform a staining process, the washing method comprising:
receiving information related to a washing condition,
wherein the receiving of the information includes: presenting a reception screen for receiving a setting of a washing condition; and receiving, as the information, a setting of a washing condition through the reception screen, wherein the setting includes a set value of a washing liquid concentration and a set value of a holding time; and
executing a washing operation for the staining bath, according to the received information,
wherein the executing of the washing operation includes:
discharging the staining liquid from the staining bath;
supplying a washing liquid to the staining bath; and
discharging the washing liquid from the staining bath, wherein the holding time is a time period from when the washing liquid is supplied to the staining bath to when the washing liquid is discharged from the staining bath.

2. The washing method of claim 1 , wherein
the smear sample preparing apparatus is configured to operate in a plurality of modes, and
the plurality of modes include a first mode in which the reception screen is displayed, and a second mode in which the reception screen is not displayed.

3. The washing method of claim 1 , wherein the receiving of the information includes:
presenting an operation screen for receiving an instruction to execute a first washing operation of executing a washing operation for the staining bath with a first washing condition, or a second washing operation of executing a washing operation for the staining bath with a second washing condition different from the first washing condition; and
receiving, as the information, an instruction to execute at least one of the first washing operation and the second washing operation.

4. The washing method of claim 1 , wherein the receiving of the information includes:
selectively presenting a plurality of washing conditions; and
receiving, as the information, selection of any of the presented washing conditions.

5. The washing method of claim 1 , wherein the washing condition includes a condition related to a washing time.

6. The washing method of claim 1 , wherein the receiving of the information includes:
obtaining, as the information, information related to a degree of dirt of the staining bath; and
setting a washing condition based on the obtained information.

7. The washing method of claim 1 , wherein the receiving of the information includes:
obtaining, as the information, information related to a state of the smear sample preparing apparatus; and
setting a washing condition based on the obtained information.

8. The washing method of claim 7 , wherein
the information related to the state of the smear sample preparing apparatus includes at least one of: information related to an operation schedule of the smear sample preparing apparatus; information related to a discharge function for liquid in the staining bath; information related to a continuous operation time of the smear sample preparing apparatus; and information related to an observation result of a smear sample slide smeared by the smear sample preparing apparatus.

9. The washing method of claim 1 , wherein the receiving of the information includes:
obtaining, as the information, information related to a state of the smear sample preparing apparatus;
presenting a recommendation screen for receiving setting of a washing condition based on the obtained information; and
receiving, as the information, setting of a washing condition through the recommendation screen.

10. The washing method of claim 9 , wherein the presenting of the recommendation screen includes presenting information related to the state of the smear sample preparing apparatus.

11. The washing method of claim 1 , wherein the washing condition includes a condition related to concentration of a washing liquid, and the concentration of the washing liquid varies.

12. The washing method of claim 11 , wherein the executing of the washing operation includes preparing the washing liquid at a mixing ratio of the washing liquid in undiluted form to a diluent, according to the washing condition.

13. The washing method of claim 1 , wherein the executing of the washing operation further includes:
supplying the staining liquid to the staining bath.

14. The washing method of claim 13 , wherein
a first staining liquid replacement process of performing the executing of the washing operation, and
a second staining liquid replacement process of performing the discharging of the staining liquid from the staining bath, and the supplying of the staining liquid to the staining bath without the washing liquid being supplied to the staining bath, are selectively executed.

15. The washing method of claim 14 , wherein
the staining bath includes a plurality of baths storing therein different liquids, and
the first staining liquid replacement process or the second staining liquid replacement process is selectively executed for each of the plurality of baths.

16. The washing method of claim 14 , wherein
the staining bath includes a plurality of baths storing different liquids therein, and
the first staining liquid replacement process is executed for a bath storing a predetermined liquid therein among the plurality of baths, according to the selection.

17. The washing method of claim 16 , wherein the predetermined liquid is a diluted staining liquid containing phosphate buffer.

18. A washing method for a staining bath in a smear sample preparing apparatus operable in a plurality of operation modes, the staining bath being able to accommodate a glass slide having a specimen smeared thereon, the staining bath being able to store therein a staining liquid for staining the specimen smeared on the glass slide to perform a staining process, the washing method comprising:
receiving information related to a washing condition,
wherein the receiving of the information includes: presenting a reception screen for receiving a setting of a washing condition; and receiving, as the information, a setting of a washing condition through the reception screen, wherein the setting includes a set value of a washing liquid concentration and a set value of a holding time, wherein the holding time is a time period from when a washing liquid is supplied to the staining bath to when the washing liquid is discharged from the staining bath;
selecting at least one operation mode from among the plurality of operation modes according to the received information; and
executing a washing operation for the staining bath, according to the selected operation mode.
