摘要:
The present invention provides a highly reliable reaction cuvette in which air bubbles are adhered little and mutual contamination can be prevented among samples and reagents in adjoining reaction cuvettes, a method of surface treatment for a reaction cuvette, and an automatic analyzer with the reaction cuvette mounted therein. The reaction cuvette according to the present invention, in which a sample and a reagent are mixed with each other and its concentration is measured, has an area subjected to hydrophilic treatment by electric discharging on inner and outer surfaces of the reaction cuvette. Further the reaction cuvette has a container-like form with its upper portion opened to provide an opening and its lower portion closed to provide a bottom. The hydrophilic area is present from a bottom of the reaction cuvette up to a midway to the opening.

The present invention provides reaction cells capable of maintaining stable analytical performance by preventing bubble adhesion and reducing sample carryover even if the amount of sample liquid for a single test is further reduced in the future. The invention further provides an automatic analyzer that uses the reaction cells and a method for enhancing the hydrophilicity of the inner surfaces of the reaction cells. According to the invention, a reaction cell has a first electrode inserted thereinto and a second electrode disposed on the bottom side of the reaction cell. A voltage is applied between the first electrode and the second electrode to cause electric discharge between the electrodes. This allows for enhancing only the hydrophilicity of the bottom inner surface and the four bottom corners of the reaction cell to which large bubbles adhere easily.

A device for retaining a person's seated position is provided as seats for vehicles, for example. The device has a seat member and an upper body support member. The seat member has a seat surface on which a person is seated. The seat surface has a pair of reference ridges each of which is fit to a recess between a biceps femoris muscle and a semimembranosus muscle of each of thighs of the person. The upper body support member has an upper body support surface that supports an upper body back of the person. Various types of ridges are provided on the upper body support surfaces for stabilizing the upper body of the person seated on the seat.
