Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dispensing device for blood tests used when testing samples such as blood and serum by dispensing them into a large number of holes arranged in a titration plate. It will take some time to improve.

Testing of specimens such as blood and serum is usually carried out using a large number of specimen dispensing holes formed of transparent synthetic resin arranged vertically and horizontally, as shown in Figure 1. As shown in Fig. 2, the titration plate 1, which is
Each hole 10 of this titration plate 1 is placed on a mounting table movably provided below the dispensing head a of A.
Dispense the sample from each dispensing needle 11 of the dispensing head a, and apply a reaction reagent previously applied to the inner wall surface of each hole 10 or inside each hole lO... reaction reagent applied to the surface of reaction beads that have been added in advance, or
After dispensing the sample, it is reacted with the dispensed reaction reagent, and when the reaction process is completed, the results of one reaction are inspected using an optical inspection device such as a photometer. In testing a sample such as, normally, the titration plate 1 is supplied to the lower side of the dispensing head a of the dispensing apparatus A by passing under the dispensing head a on the upper surface side of the body 2 of the dispensing apparatus A. A conveyor for transporting the titration plate 1 is provided at a position that crosses left and right.

A supply hopper C, which accommodates a large number of titration plates 1 in a stacked manner and has an outlet on the lower side, is arranged above the starting end side of the transfer conveyor in the conveyance direction and is mounted on the machine body 2. Then, the titration plates 1 are fed out one by one from the outlet of the supply hopper 〇 and sent below the dispensing head a by a transfer conveyor. The titration plate 1, which has been sent below the dispensing head a and has completed the predetermined dispensing process, is received on the lower surface at an upper position on the terminal end side of the conveyor beyond the dispensing head a of the transfer conveyor. Collection hopper d with open entrance
is mounted, and the titration plate l that has completed the dispensing process is transferred by the transfer conveyor to a position below this recovery hopper ++d, and the recovery hopper d is operated to descend, or The titration plate l is pushed into the collection hopper d from the receiving port of the collection hopper d by the operation of the lifting platform arranged on the machine body 2 and mounted on the machine body 2.
We are in the process of collecting it.

Therefore, the feeding of the titration plate 1 below the dispensing head a and the collection of the titration plate 1 after the dispensing process can be automatically carried out by the supply hopper 〇, the collection hopper d, the transfer conveyor, etc. However,
Depending on the type of test, an ink page is used to maintain a constant temperature when a sample or reagent is dispensed and reacted.

In that case, remove the titration plate 1 after dispensing the sample or reagent from the body of the dispensing device A, transfer it to a separately installed thermostatic chamber, and then Since the reaction is completed by maintaining the temperature at a constant temperature, automatic processing of the titration plate 1 during the testing process is not possible.

Furthermore, the task of transferring the titration plate 1 into this constant temperature bath is performed every time the titration plate l, which has completed a predetermined dispensing process below the dispensing head a, is sent out toward the bottom of the recovery hopper d. .

The test was carried out by taking out the titration plate l from the body of the dispensing device A, carrying it to the thermostatic chamber, and loading it into the thermostatic chamber. Titration plate! When the ink page has been emptied for a predetermined period of time, the operator has to manage the time to remove the ink page, which poses a problem of placing a heavy burden on the inspection technician.

The present invention has been made to solve this problem, and after a predetermined dispensing process is completed below the dispensing head a of the dispensing device faA, the collection hopper d is opened from below the dispensing head a. The titration plates 1 sent downward are sent into the recovery hopper d one after another without being removed from the body of the dispensing device 1A, and a predetermined incubation is carried out in the recovery hopper d, thereby ink ink. The purpose of the present invention is to provide a new means that makes it possible to omit complicated operations and troublesome management for servicing.

In the present invention, as a means to achieve this objective, a titration plate transfer conveyor is mounted on the top side of one machine, and titration plates are transferred one by one from the outlet at the lower end above the transfer conveyor. A feeding hopper, a dispensing head with a dispensing needle on the bottom surface, and a collection hopper that receives the titration plate from the receiving port at the lower end are mounted on the machine in parallel in the conveying direction of the conveyor. A blood dispensing device characterized in that the outer periphery of the collection hopper except for the receiving port is surrounded by a partition wall, and a heater is installed to maintain the inside of the collection hopper at a constant temperature so as to double as a constant temperature bath. The present invention proposes a dispensing device for inspection.

In the case of an inspection, the inspection process can be automatically processed.

As explained above, in the blood test dispensing device according to the present invention, the transfer conveyor e of the titration plate 1 is mounted on the upper surface side of the #1 body 2, and the lower end outlet is placed above the transfer conveyor e. A supply hopper C that feeds out titration plates 1 one by one from 31, a dispensing head a provided with a dispensing needle 11 on the lower surface, and a collection hopper d that receives titration plates 1 from a receiving port 41 at the lower end. , in order, in the dispensing device mounted on the machine body 2 in parallel in the transport direction of the transfer conveyor e, the collection hopper d is surrounded by a partition wall 44 on its outer periphery except for the receiving port 41, and its interior is maintained at a constant temperature. The dispensing bag 2? After completing a predetermined dispensing process under the dispensing head a of A, the titration plate 1 that is sent out from below the dispensing head a to below the collection hopper d is removed from the body of the dispensing apparatus A. It becomes possible to sequentially feed the materials into one collection squirt bar d and perform predetermined incubation within the collection hopper d, thereby making it possible to omit complicated operations and troublesome management for incubation.

In addition, if the upper part of the collection hopper d and the upper part of the supply hopper ○ are connected by a transfer conveyor g, the titration plates collected in the collection hopper d are sequentially returned to the upper part of the supply hopper 〇 for circulation.
