Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an attachment for a microplate,
In particular, the present invention relates to a microplate attachment suitable for use in a microplate used in a device for determining particle aggregation patterns in clinical tests.

[Conventional technology]

Various devices have been published as devices for determining particle aggregation patterns in clinical tests.

[Problem to be solved by the invention]

Each of these determination devices has its own system and handling depending on the company, so in most cases, dedicated microplates and dedicated attachments are used. This has resulted in the inconvenience that microplate attachments from other manufacturers cannot be used.

On the other hand, in joint research, etc., various test equipment is brought in, and in order to operate judgment devices from different manufacturers under the same conditions, each device must use attachments from other manufacturers. This situation arises.

[Purpose of the invention]

The purpose of the present invention is to improve the inconveniences of the conventional examples, and in particular, to provide a microplate for use in an agglutination determination apparatus that can be installed and used in an extremely easy and detachable manner, regardless of which company's microplate is used. The purpose is to provide attachment.

[Means to solve the problem]

The present invention includes a rectangular frame formed to correspond to the main body case of the aggregation determining device, and knock pin holes for engaging the main body case formed in at least three places on the frame. A portion of the frame is provided with a plate abutting surface that slightly protrudes inward. The frame body portion on the side facing the plate contact surface is equipped with at least two spring contacts configured to be capable of protruding or retracting toward the plate contact surface. This aims to achieve the above-mentioned purpose.

[Embodiments of the invention]

A first embodiment of the present invention will be described below with reference to FIGS. 1 to 6.

The embodiment shown in FIGS. 1 to 6 includes a rectangular frame 1 formed to correspond to the main body case of the aggregation determination device, and main body case retainers formed at at least three places on this frame 1. It has a knock pin hole 2°3 for use. frame l
A part of the plate is provided with a plate abutment surface IA that slightly protrudes inward, and the frame portion on the side opposite to the plate abutment surface IA is capable of protruding or retreating toward the plate abutment surface IA. is equipped with at least two spring contacts 4,4.

As shown in FIG. 2, a bushing 11 (see FIG. 3) having a Teflon coat 10 on the inside is press-fitted into the dowel pin hole 2.3 shown in FIG. This results in
It is possible to smoothly insert and remove the dowel pin provided in advance on the main body case of the agglomeration determining device (not shown).

Further, the spring contact 4 shown in FIG. 1 has a screw hole 4A penetrating from the outer circumferential surface 1a of the frame body 1 toward the inner circumferential surface 1b, as shown in FIGS. 4 to 6; The structure includes an adjustment screw 4B that is screwed into this screw hole 4A. Among these, the tip of the adjustment screw 4B has a contact head 4a for pressing the side end surface of the microplate.
And, the tip cover 4 equipped around the hit head 4a
It is equipped with b. The contact head 4a and the tip cover 4b are each formed to have a circumferential size that fits within the screw hole 4A.

Further, the head of the adjusting screw 4B is provided with an adjusting hexagonal head 4E in a concave shape along the central axis.

Furthermore, a compression spring 4C is housed in the adjustment screw 4B, so that an appropriate pressing force is constantly applied to the contact head 4a toward a microplate (not shown).

Therefore, when using the microplate attachment 1 according to the first embodiment, it is possible to easily handle microplates of slightly different sizes by adjusting the spring contacts 4.5 described above. In addition, for microplates with significantly different sizes, it is possible to sufficiently accommodate microplates by preparing multiple microplates of different sizes with common dowel pin holes in advance. .

Therefore, in the prior art, a situation occurred in which a microplate that matched the determination device for recognizing the agglomeration pattern had to be used, whereas the attachment of this first embodiment can be used. This has the advantage that any one determination device can be sufficiently adapted to many different microplates.

[Second example] Next, a second embodiment will be described based on FIG. 7.

The second embodiment shown in FIG. 7 is characterized in that a plate contact surface IA and a spring contact 4.4 are provided on two sets of opposing inner surfaces of the frame IO. The other configurations are the same as those of the first embodiment described above.

Therefore, this second embodiment has the advantage that it can be used satisfactorily even for microplates whose entire periphery is formed small.

[Third example] Next, a third embodiment will be described based on FIG. 8.

In the third embodiment shown in FIG. 8, the frame 1 is provided with a plate contact surface LA and a pair of spring contacts 4, 4, and a portion of the frame 11 in the direction perpendicular to this is provided with a plate at the center of its upper end. There is a notch 20 for inserting and removing the microplate.
20 is provided. In this case, the knock pin holes 2° 3 are provided on both sides of one notch 20. The other configurations are the same as those of the first embodiment described above.

Even in this case, in addition to having the same effect as the first embodiment described above, there is an advantage that the microplate can be easily inserted and removed, and therefore various particle aggregation patterns can be determined more quickly. .

〔Effect of the invention〕

As described above, according to the present invention, by using the present invention, it is possible to use a single determination device to handle many different microplates, and the determination device can be easily inserted and removed from the main body case. Because of this,
It is possible to provide an unprecedented and excellent microplate attachment suitable for use in a device for determining particle aggregation patterns in clinical tests, which can more quickly determine various particle aggregation patterns.
