Automatic analyzer
View Patent ↗An automatic analyzer provided with a roller and a reagent container shoulder presser at the position where an operator inserts a reagent container into the automatic analyzer. The reagent container is pushed while the lid of the reagent container is made to touch the upper side of the roller and the shoulder presser is made to touch the shoulder of the reagent container, and the application of upward force to the lid causes the lid of the reagent container to be half open, after which the reagent container is inserted in the analyzer.
1. An automatic analyzer comprising:
a detecting section for measuring a fixed amount of measurement target component in reaction liquid;
a reagent storage storing reagent containers and forming an enclosed housing, said reagent storage configured to store the reagent containers,
reagent containers, each having a main body housing a reagent used for analysis, an opening provided on a top of the main body, and a lid portion having a sealing member for sealing the opening by being inserted into the opening;
a lid opening/closing mechanism provided inside the reagent storage enclosure that opens and closes lids of the reagent container set in the reagent storage;
a reagent loader mechanism loading having a reagent setting section with a plurality of slots, each slot to house at least one reagent container;
a mechanism to partly open a reagent container having a plurality of mechanical elements which are respectively provided for each slot to partly open at least one reagent container by removing the sealed member from the opening of the at least one reagent container, whereby the reagent container lid is opened to a predetermined angle by the mechanism to partly open the reagent container by an operation of placing the reagent container into the respective slots of the reagent setting section, wherein when the reagent loader mechanism moves between an open position where the mechanism to partly open the container is accessible and a closed position inside the reagent storage; and
a processing mechanism for executing dispensing or stirring processing of the at least one reagent stored inside the reagent storage.
2. The automatic analyzer according to claim 1 , wherein the mechanism to partly open the reagent container lid portion includes a first roller opening the sealing member of the lid portion from the opening by contacting the lid portion from below, and
a second roller making an opening angle of the lid portion be a predetermined angle by contacting the lid portion opened by the first roller from above.
3. The automatic analyzer according to claim 2 , wherein a position where the lid portion contacts the first roller is a vicinity of the uppermost part of the first roller.
4. The automatic analyzer according to claim 1 , wherein a plurality of first rollers are provided.
5. The automatic analyzer according to claim 1 , further including resilient members holding the mechanism to partly open the reagent container lid portion so as to permit movement upward and downward.
6. The automatic analyzer according to claim 1 , wherein the reagent loader mechanism has a function of discharging the reagent container inside the reagent storage, and
the mechanism to partly open the reagent container lid portion has a function of inserting the sealing member into the opening to make the opening be a sealed state by an operation of taking the reagent container out from the reagent loader mechanism.
7. The automatic analyzer according to claim 6 , wherein the mechanism to partly open the reagent container lid portion includes a third roller adjusting a position of the lid portion so as to cover the opening by contacting the lid portion of the reagent container taken out from the reagent loader mechanism from above.
8. The automatic analyzer according to claim 1 ,
wherein the mechanism to partly open the reagent container lid portion is movably mounted to an outside part of the reagent storage so the mechanism is movable to a position permitting access thereto for cleaning and/or maintenance.
9. The automatic analyzer according to claim 1 ,
wherein the reagent loader mechanism has a means for detecting that the reagent container is positively inserted into reagent loader mechanism.
10. The automatic analyzer according to claim 1 ,
wherein the reagent loader mechanism has a means for detecting a contact position before the reagent setting section operates when there is a possibility that the reagent container contacts neighboring members by operating the reagent loader mechanism in a state where the reagent container is not positively pushed into the reagent setting section.
11. The automatic analyzer according to claim 1 ,
further including means for detecting a contact as well as stopping an operation of the reagent loader mechanism before the contact position is damaged when the reagent loader mechanism operates and the reagent container contacts neighboring members in a state where the reagent container is not positively pushed into the reagent setting section.
