Abstract

PURPOSE:To make the efficient production of a slide having high accuracy and good quality possible by blanking preliminarily a mount for forming a drawn part from a base material consisting of a plastic sheet into a rectangular element. CONSTITUTION:The element 2 for the rectangular mount is blanked from a base mount material 1 consisting of the plastic sheet and 1 or >=2 recessed drawn parts 5 are formed atop the element 2. A film 6 for chemical analysis is loaded into each part 5. An element 7 for covering the mount is supplied atop the element 2 and after both elements 2, 7 are adhered, the element is cut to the size corresponding to the slide for chemical analysis along the non-drawn part. The trouble arising from the elongation and hunting of the base material for the mount and mount cover and the permanent winding set of the base material is thus eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a method for manufacturing a chemical analysis slide for chemically analyzing and measuring a liquid sample.

[Conventional technology]

Generally for liquid samples such as blood and serum.

Chemical analysis using a reaction reagent is performed when it is necessary to know whether or not a particular component is contained in the liquid sample, or its content. There are two methods for chemical analysis of liquid samples: dry methods and wet methods.

Among these, the dry method uses chemical analysis slides.

A liquid sample to be analyzed is dripped onto the slide, placed in a thermostatic chamber for reaction, and the liquid sample reacts with the reagent. This is a method of measurement and detection using an optical concentration meter or other means, and is very convenient in that a liquid sample can actually be treated as a solid.

However, conventionally, in order to continuously obtain products shaped like slide mounts for chemical analysis, a long base material wound into a roll was used.

The mount and mount cover obtained by this method have a long section from when the base material is pulled out from the reel until it is finally cut, and as a result, the base material may stretch or meander during running.
The molding position of the narrowing part performed at the beginning of the travel of the base material on the mount side may be misaligned with the dispensing hole pre-drilled in the base material on the mount cover side, or the shape of both base materials may be distorted. Therefore, it is difficult to produce chemical analysis slides with high precision and good quality because flatness cannot be obtained and the degree of curling causes variations in adhesion to the concentration measuring means.

[Object of the invention] This invention eliminates troubles caused by elongation and meandering of the base material of the mount and mount cover, and @12f of the base material, and makes it possible to efficiently manufacture chemical analysis slides with high precision and good quality. The purpose is to provide a method for molding chemical analysis slides.

[Structure of the invention]

This invention punches out a rectangular mounting element from a plastic sheet base material, forms one or more concave narrowed parts on the upper surface of the mount, fills the narrowed parts with a chemical analysis film, and mounts the element on the upper surface of the mount. After the cover is supplied and adhered, it is cut along the non-squeezed portion into a size corresponding to a chemical analysis slide.

〔Example〕

Next, the present invention will be described based on an embodiment shown in the accompanying drawings.

1 is a mounting base material, and 2 is a mounting element that is punched out so as to include one or more (in the illustrated example, five regions J!3i) of the mount punching area A defined on the base material 1. be. The mounting element 2 has through holes 3.3' for positioning at both lengthwise ends at the same time as the punching.
A photometric through hole 4 is formed at the center of the mount punching area A.

As shown in FIG.
The seven-shear mechanism I2 sequentially supplies the fuel to the travel line 10 at a constant timing. There is a claw body 13 on the running line 1° that moves back and forth with a constant stroke, mooring and sending the supplied mounting element 2 protruding onto the line when moving forward, and sinking below the line when moving backward. A one-way feed mechanism 14 is provided.

The mounting element 2, which is intermittently sequentially fed on the traveling line 10 by the conveyor fjufM 14, is a positioning element 2.
TL3. At the first station, the press molding machine 15 is operated to form the central part of the upper surface (through-hole for photometry) into the mount punching area determined as described above. A concave narrowed portion 5 is formed so that the concave portion 4 is centered. As mentioned above, if the photometric through-hole 4 is not drilled in the mounting element 2 in advance, it is also possible to perform this molding using a pressure forming or vacuum forming machine.
(j'; I
It will be possible to do so.

The mounting element 2 with the narrowed part 5 formed therein reaches the second station by the feeding operation of the first general feeding mechanism 14 in a positioned state, and the chemical analysis film 6 is filled into the narrowed part 5 by the feeding mechanism 16. be done. As shown in FIG. 3, the chemical analysis film 4 is formed by forming a reagent N6b on the upper surface of a transparent support 6a, and laminating a developing layer 6c on top of the reagent N6b. The spreading layer 6C is for spreading the liquid sample dropped thereon in the surface direction and causing it to react with the reagent layer 6b.

As mentioned above, after the chemical analysis film 6 is filled into the narrowing part 5, the mounting element 2 reaches the third station, where the mounting cover element 7 is placed on the upper surface of the mounting element 2 and is appropriately supplied from the storage magazine 17. can be stacked using The mount cover element 7 is punched out in the same shape and size from the same planar base material (not shown) as the mount element 2, and is located at a position corresponding to the center of the narrowed part 5 of the mount element 2. A sample dispensing hole 7a is drilled in advance in the sample dispensing hole 7a, and positioning holes 7b and 7b' are drilled in both of the holes 6ii1, so that the mounting element 2 is properly stacked.

Welding machine 1 installed at the fourth station after overlapping mount cover element 7 on mount element 2
8 is activated and the two are bonded together. In addition, 1 car Niremen I-
2 and 7 may be bonded by means other than welding, such as adhesive bonding.

After bonding, both elements 2.7 are cut out in the mount punching area A by the operation of the cutting machine 19 at the fifth station.
The slides are cut along the lines and transported to the next process as chemical analysis slides.

In addition, in the above-mentioned manufacturing process, it is also possible to simultaneously incorporate a chemical analysis film coating process on the above-mentioned traveling line. In this case, when a material with good transparency is used as the mounting element, that is, the mounting base material, the transparent support 6a of the chemical analysis film 6 can also be used, and an analysis slide without through holes for photometry can be manufactured. It is also possible. In addition, the mount and mount cover base material are made with textured surfaces as necessary, so that scratches on the top surface and
It makes dirt less noticeable and improves the product value.

It is also possible to directly write necessary information with a pencil or the like.

〔Effect of the invention〕

As described above, the present invention forms one or more concave narrowed portions on the upper surface of the mount, fills the narrowed portions with a chemical analysis film, and supplies and adheres the mount cover to the upper surface of the mount.

In a method of manufacturing a chemical analysis slide that is cut along the non-restricted area into a size corresponding to the chemical analysis slide, the mount that forms the recessed area.

Since rectangular elements are punched out in advance from the plastic sheet base material, problems such as elongation and meandering that occur when the base material is run over long distances to perform various processes, as in the past, are avoided. This method has the excellent effect of efficiently producing chemical analysis slides with high precision and good quality without the problem of curling caused by the S-curve of the base material.
