Abstract

Abstract This invention relates to an incubator for chemical-analytical slides which are utilized for quantitative analysis of various components in a body fluid such as blood and urine. In an incubator having a cell into which a chemical-analytical slide is inserted and placed, a hole for photometry which is provided to a part of the slide placing-face of the above cell, a sealing member which is pushed to seal the opening for spotting of the slide, a pushing means which pushes the sealing member against the above hole for photometry, and a heating means which heats the slide, the improvement which is characterized in that the sealing member comprises a sealing part made of plastic which covers the opening for spotting and a pushing part being wear resistant which pushes the slide frame of slide. In the incubator of the invention, when a chemical-analytical slide is inserted into the cell, scratches nor abrasion are not occurred at the reverse face of the sealing member, because the position to which a strong sliding force or butting force is added is formed of a wear resistant material.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 118 words
In an incubator having a cell into which a chemical-analytical slide is inserted and placed, a hole for photometry which is provided in a portion of a slide receiving-face of said cell, a sealing member which is pushed to seal the opening for spotting said slide with a liquid, an urging means which urges said sealing member against said hole for photometry, and a heating means which heats said slide, the improvement which is characterized in that said sealing member comprises a sealing part made of thermoplastic polymer which completely covers said opening for spotting and a pressure part of wear resistant material which presses the slide frame of said slide toward the slide receiving-face of said cell.
Claim 2
Dependent Claim 118 words
In an incubator having a cell into which a chemical-analytical slide is inserted and placed, a hole for photometry which is provided in a portion of a slide receiving-face of said cell, a sealing member which is pushed to seal the opening for spotting said slide with a liquid, an urging means which urges said sealing member against said hole for photometry, and a heating means which heats said slide, the improvement which is characterized in that said sealing member comprises a sealing part made of thermoplastic polymer which completely covers said opening for spotting and a pressure part of wear resistant material which presses the slide frame of said slide toward the slide receiving-face of said cell.
Claim 3
Dependent Claim 13 words
The incubator of claim 1 wherein said pressure part is made of metal.
Claim 4
Dependent Claim 24 words
The incubator of claim 1 wherein the lower surface of said sealing part and the lower surface of said pressure part form one plane.
Claim 5
Dependent Claim 29 words
The incubator of claim 1 wherein most of or the whole lower surface of said sealing part is provided slightly indented from the lower surface of said pressure part.
