[0018]

[Table 1] Next, the materials of the urine absorber 14 and the back receiving plate 35 will be described.

The urine absorbent body urine absorbent body 14 is winding core 31 of the water-dispersible of fiber material
Is wound with a wrapping paper 32 made of water-soluble paper or water-dispersible paper and adhered with an adhesive. When discarded in the toilet, the urine absorber 14 is dispersed in the running water of the toilet as a whole. Hereinafter, each component of the urine absorber will be described.

(Core) The core material is not particularly limited as long as it is a fibrous substance which does not adsorb the detection component of the specimen and has water absorbability, and is a synthetic material such as polyester, cellulose acetate, regenerated cellulose, nylon fiber and the like. Fiber or hemp
Natural materials such as silk are desirable.

The thickness of the fiber is important for providing an effective capillary action, and differs from the water absorption of the material.
Denier is desirable.

Fiber density is also an important factor in water absorption performance,
For example, in the case of 3 denier polyester fiber, 0.12
g / cm ³ , no water absorption occurs, but 0.3 g / cm ³
Then, a 5 cm urine absorber is absorbed in about 15 seconds. Although the water absorption performance increases as the density increases, the internal pressure increases due to the expansion of the core portion due to the water absorption, and if the strength of the adhesive for holding the paper wrapping portion becomes greater than the tensile strength of the paper wrapping, rupture occurs. This increase in internal pressure serves as a driving force for collapse when thrown into running water such as a toilet, and if the density is too low, decomposition in running water does not proceed in a short time. Also,
The internal pressure during water absorption can be controlled by winding the core with a wrapping paper and then performing a heat treatment or a pressure heat treatment at a temperature near the glass transition temperature Tg of the core. From the above, the density of the core fiber is 0.1 to 0.6 g / cm.
³ is preferred.

The surfactant treatment for the core material is
It plays a role in enhancing permeability to fibers, improving water absorption performance, and promoting dispersion of fibers in running water. It is desirable that the surfactant used does not inhibit the reaction of the determination part, and a nonionic surfactant is used, such as polyoxyethylene oleyl ether, oxyethylene propyl ether, sorbitan monooleate, and polyethylene glycol isooctyl phenol ether. Is used.

(Wrapping paper) As a wrapping paper, a water-soluble or water-dispersible paper material is used. Here, the water-soluble paper is a paper that dissolves in water, and the water-dispersible paper is a paper that separates in water and is dispersed to a single fiber. Examples of such paper include Disolvo series manufactured by Mishima Paper Co., Ltd., water-soluble paper MDP,
There are CD-2 and water-dispersible paper CD-2N. Other PV
A film of a water-soluble polymer such as P or PVA,
Water-soluble paper or water-dispersible paper laminated with a water-soluble film is also used. In some cases, a water-soluble / water-insoluble resin is applied to these papers / films to adjust the dispersion time. Although a certain degree of flexibility is required for the density depending on the properties of the wrapping paper, it is preferably ²⁰ to 100 g / m ² .

In addition, it is important to control the water resistance of the wrapping paper, that is, to control the water resistance in still water and the dispersibility in running water, so that a water-soluble / water-insoluble resin can be applied to the wrapping paper. . As the water-soluble resin, polyvinylpyrrolidone, hydroxypropylcellulose, polyethylene glycol,
Polyvinyl alcohol and the like are desirable, shellac, polyvinyl butyral, polymethacrylic acid, hydroxypropyl methylcellulose phthalate for the water-insoluble resin,
There are carboxymethylethylcellulose, ethylcellulose and the like, which are used alone or as a mixture and dissolved in a solvent. The solvents for these resins are alcoholic,
Ketone solvents, cellosolve solvents, benzene solvents and the like are conceivable. The printing method varies depending on the properties of the wrapping paper, but may be dip coating, gravure printing, screen printing, etc., a full-surface impregnation treatment, a single-sided treatment, a double-sided treatment, or a multilayer coating. For example, in the case of a highly water-soluble resin, a water-insoluble resin is impregnated, or a core material having a high internal pressure is coated on one side with a hydrophobic resin on the inside of a wrapping paper. In addition, a treatment such as one-side coating of a water-soluble resin on the outside of the wrapping paper can be performed.

When urine is applied to the urine absorber, the sample liquid moves from the wrapping paper to the core and moves to one side of the diagnosis due to the capillary action of the core fiber. However, if the transfer speed from the wrapping paper to the core material is low, a sufficient amount of urine cannot be supplied to the core material by urination for about 5 seconds. In such a case, it is effective to perform window opening processing on the wrapping paper. The window is desirably large to some extent, but if it is too large, it may be broken by the internal pressure of the core material. Also, a plurality of windows can be provided, and a notch such as perforation processing may be provided. Further, by making a cut in the wrapping paper in this manner, the dispersion of the urine absorbent in running water is promoted.

(Adhesive) The wrapping paper is adhered by an adhesive. Adhesive is ethylene-vinyl acetate copolymer emulsion,
A polyacrylic acid-based or polyvinyl alkyl ether-based water-insoluble adhesive, a cellulose acetate, or a PVA-based water-soluble adhesive are used.

(Manufacturing method) The urine absorbent composed of the above components is manufactured through the same steps as those of a general cigarette filter. That is, the fibers of the core material are formed through a circular mold, and at the same time as passing through the mold, a roll-shaped wrapping paper having a length obtained by adding a margin to the cross-sectional diameter of the urine absorber is applied. Next, after wrapping one end of the wrapping paper with the adhesive in drops,
It passes through the drying zone and is cut to any length. The urine absorber thus formed is formed into an arbitrary shape such as a cylindrical shape or a quadrangular prism by thermocompression bonding.

[0029] as a back receiving plate back receiving plate, Mishima Paper dissolver volume series MDP (water-soluble paper), CD-2 (water-soluble paper) of (stock), or C
D-2N (water-disintegrable paper) is used. Therefore, when discarded in a toilet, the back receiving plate is dissolved or dispersed in running water.

Next, the operation of the present embodiment having such a configuration will be described.

First, the portable diagnostic device in the state shown in FIG. 3 is taken out of a packaging container (not shown), and the sheath cap 18 is removed from the attachment portion 19a as shown in FIGS. Next, the sheath-shaped cap 18 is attached to the attachment portion 19b of the connection holder 17, and the entire length is increased so that the whole can be easily handled. Then, the holder 1 is bent with respect to the connection holder 17 as shown in FIG. The urine wire is brought into contact with the distal end portion 14c of the urine absorber 14 in the toilet with the cap 18 held therebetween.

In this case, a part of the urine wire which has fallen off the distal end portion 14c hits the protruding portion 35b of the back receiving plate 35, and then the urine moves from the protruding portion 35b to the distal end portion 14c side and is absorbed by the urine absorber 14. Is done. The back receiving plate 35 is provided with the urine absorber 14.
In order to cover the rear surface of the distal end portion 14c, the water in the toilet is protected from being applied to the urine absorber 14 from the rear surface.

Next, urine absorption is confirmed by the urine wetness checker 25 printed on the urine absorber 14 turning fluorescent yellow. When left for a few minutes, urine permeates the diagnostic strip 12 via the urine absorber 14. In this case, the diagnostic piece 1
Two lines are confirmed. For example, one line is negative and two lines are positive. After the diagnosis, the urine absorber 14 and the back receiving plate 35 wet with urine are pushed out by sliding the slider 11 and discarded in the toilet. In this case, the urine absorber 14 and the back receiving plate 35 are dissolved or dispersed in the running water of the toilet as described above. Next, the sheath cap 18
Is removed from the adhered portion 19b and the adhered portion 19a is again covered,
Cover the holder 1 and return to the state of FIG. The determination result can be visually confirmed through the transparent window 2 and the window 24.

As described above, according to the present embodiment, when the urine is brought into contact with the distal end portion 14c of the urine absorber 14, a part of the urine which has come off the urine absorber 14 is projected from the back receiving plate 35. By contacting the portion 35b, urine can be transferred from the protrusion 35b to the urine absorber 14 and absorbed. For this reason, urine can be absorbed more reliably by the urine absorber 14, and the urine absorber 1
4 can be protected from behind. Further, after use, the urine absorber 14 and the back receiving plate 35 can be discarded in the toilet.

Next, another embodiment of the portable diagnostic apparatus will be described with reference to FIGS.

The embodiment shown in FIGS. 5 to 7 is the same as the embodiment shown in FIGS. 1 to 4 except for the configuration of the back receiving plate. First, as shown in FIG.
A back support plate 37 is attached to the back surface of 4, and the back support plate 37 is foldable via a plurality of fold lines 38. That is, before use, the back receiving plate 37 is folded via the folding line 38 and contracted to the same width as the urine absorber 14. In use, the back receiving plate 37 is expanded laterally to form an empty portion 37a protruding on both sides of the urine absorber 14.

As shown in FIG. 6, a fan-shaped back receiving plate 39 may be attached to the back of the urine absorber 14. In FIG. 6, the back receiving plate 39 has a protruding portion 39 a protruding on both sides of the urine absorber 14.

Further, as shown in FIG. 7, a rectangular back receiving plate 40 is attached to the back of the urine absorber 14. The back receiving plate 40 is provided with a protrusion 4 protruding to both sides of the urine absorber 14.
0a, and a holder 1
A fold curve 41 extending in the longitudinal direction is formed. Before use, the protruding portions 40a protruding to both sides are folded toward the urine absorber 14 via the folding curve 41, and the width of the back receiving plate 40 is reduced. When used, the protruding portion 40a is expanded,
In this case, the protrusion 40a is slightly bent toward the urine absorber 14 via the bending curve 41.

Although the diagnosis of pregnancy has been described in each of the above embodiments, the present invention can also be applied to tests for urine pH, protein, sugar, occult blood, albumin, urobilinogen, nitrogen and the like.

It is not always necessary to use a water-soluble or water-dispersible material as the urine absorber 14. In this case, a plastic material or a normal paper material can be used as the back receiving plate 35.

In each of the above embodiments, an example is shown in which the transparent window 2 is provided with an opening. However, a transparent material may be fitted into the transparent window 2 or may be left open. . When a transparent material is fitted into the see-through window 2, the transparent material may be fitted into the window 24. Further, the upper holder member 1a or the entire holder 1 may be formed of a transparent material so that the inside of the holder 1 can be observed. In this case, the entire sheath cap 18 may be formed of a transparent material.

Further, an arbitrary character such as a telephone number of a manufacturer may be formed in a convex shape on the surface of the sheath-shaped cap 18 by embossing.

Next, referring to FIGS. 8A and 8B, the urine absorbent 14
A modified example of the above will be described. As shown in FIG. 8A, a urine wetness checker 55 is printed on the urine absorber 14. A plurality of the urine wetness checkers 55 are provided in a circular shape, and the diameter thereof gradually decreases from the distal end toward the proximal end. In addition, as shown in FIG. 8B, the urine wetness checker portion 56 may be formed in a stripe shape. The three urine wetness checkers 56 shown in FIG. 8B are formed at equal intervals. 8 (a) and 8 (b), the urine wetness checkers 55 and 56 are indicated by solid lines for convenience.

[0044]

As described above, according to the present invention,
When the urine is brought into contact with the tip of the urine absorber, a portion of the urine removed from the urine absorber is applied to the protrusion of the back plate to transfer urine from the protrusion to the urine absorber. it can. For this reason, urine can be more reliably absorbed by the urine absorber. In addition, the urine absorber can be protected from the back by the back receiving plate so as to prevent water from flowing in the toilet, thereby preventing the water other than urine from being absorbed by the urine absorber and preventing an accurate diagnosis.
