Description

【０００１】
【発明の属する技術分野】
本発明は、専門医の診断を要することなく、例えば女性が自由に而も任意に妊娠しているかどうかの検査がなしうる携帯用診断具において、特に尿導入部分の改善に関する。
【０００２】
【発明の技術的背景】
尿をかけることによって妊娠の有無を検査する、いわゆる妊娠診断薬が多数上市されている。この種診断具は、尿吸収素材からなる採尿部先端に尿をかけると、尿が浸透しながら試験部まで展開し、その間に所定の反応が行われる原理である。
この尿しみ込み導入妊娠検査具において、測定に十分な量の尿が吸収体にかからない（従って十分量の尿が試験部に導入されない）ため、判定不良となる事故を避ける目的で、各社とも十分量（５秒以上）の尿をかけることを添付文書などで指示している。ところが、これによって、十分量の尿がかかっているにもかかわらず、所定時間内に結果が表示されず最終的に測定不能となる事故が逆に増加することになってきた。前者の尿量不足に基づく事故は因果関係が容易に推定できるが、後者の場合は容易でないことは説明を要しない。加えて、後者の場合の事故原因の究明は、
（１）この現象は極めてまれに起るものであること（概ね、１，０００回に１度の確率で発生している）、
（２）女性が自分自身で直接器具に尿をかける方式の検査であること。
などのため、実際に観察することも不可能であり、原因の究明自体が困難を極めた。そのため各社とも商品クレーム処理法としては新品との交換しかないのが実情であった。そこで、考えられるあらゆる可能性を想定した再現実験を行ない、鋭意研究した結果、以下の使用状況で起こり得ることを突き止めることができた。即ち、図１２に示すように、ホルダー１の一端を握り、尿吸収体２のある他端を下向き姿勢にして尿をかけるのが正しい使用法であるが、図１３のように、尿吸収体２を上方に向けた場合で、かつ尿をかけ過ぎた場合に判定事故が発生し易いことが判明した。なお、尿吸収体２が上方に向く上述の場合に比べれば発生頻度ははるかに低いものの、図１４のように、尿吸収体２が水平に近い場合でも尿をかけ過ぎた場合にも発生し得ることも判明した。
次に、これらの使用状況で起る現象を詳細に解明をすすめた結果、以下共通した現象に起因するものであることを見いだした。即ち、採尿部先端に尿をかけると尿が吸収浸透しながら試験部まで徐々に展開し、その間に所定の反応が行われるのであるが、尿吸収体２の最大含水量を超えて尿がかかると、図１３，１４に示すように吸収しきれずオーバーフローが始まる。このオーバーフローは、尿吸収体２の外部表面を流れるオーバーフロー３と、尿吸収体２の内部を流れるオーバーフロー４とに分けられるが、重力に支配されているため独立した流れということではない。
本来の使用状況、即ち、採尿部先端である尿吸収体２が下方に向いている場合では、図１２のように、オーバーフロー分の尿は自然と流下しそのまま落下排出される。しかし、図１３のように先端が上方に向いている場合には、オーバーフロー３の大部分は外部流として排出されるものの、一部は内部オーバーフロー４の発生に寄与し、本体内部に侵入し、場合によっては正常の経路以外の経路を通って試験部に到達することもある。この侵入尿が、本来の経路で浸透して試験部に到達する浸透展開時間よりも早く、試験部もしくはその端部に付着することになったならば、本来の経路からの尿の浸透展開を阻害することになる。つまり、十分量の尿がかかっているにもかかわらず、所定時間（通常数分）内に結果が表示されず、最終的に測定不能となる事故は、この尿浸透展開阻害現象によるものであることを初めて突き止めることができた。従って、この現象は浸透展開方式の検査薬なら、どのメーカーの、どの機種にでも起こり得る共通の事故原因であることが初めて明らかとなった。

【０００８】
図４について第２実施例の詳細を説明する。この実施例は、前記ホルダー１１の前端部に尿吸収体１２を斜め上向きに貫通保持させるとともに、尿吸収体１２の後端部をホルダー１１の外部に突出させたもので、尿吸収体１２に吸収された過剰尿がホルダー１１外に放流されるようにしたものである。図中１５は診断片である。
【０００９】
【作用の説明】
尿吸収体１２が上向き姿勢の場合であっても、尿吸収体１２が吸収した過剰尿は全てホルダー１１から突出している尿吸収体１２から外部に放流され、従って、診断片１５に対して正常の経路以外からの過剰尿を浸透展開させることが防止され、試験片の正常反応が得られる。
【００１０】

【００１３】
【作用の説明】
ホルダー１１の先端部にかかった尿は、凸条１９によって形成された誘導路２０により尿吸収体１２と逆方向に誘導放流され、過剰尿が尿吸収体１２に吸収されず、又逃げきれない尿は凸条１９によって尿吸収体１２方向への流動が阻止され、過剰尿が尿吸収体１２に吸収されることなく、診断片１５に対して正常の経路以外からの過剰尿が浸透展開されるのを防止し、試験片の正常反応が得られる。
【００１４】
次に、図９〜図１１について第５実施例の詳細を説明する。図９に示すように、前記ホルダー１１内に収容される尿吸収体１２の下流部端面１２ａ，下流部両側面１２ｂ，下流部上面の基部端面１２ｃ及び下流部底面１２ｄに撥水加工２２を付設したものである。又図１０に示すように、前記撥水加工２２部に相当する部分を防水カバー２３にて形成し、この防水カバー２３を尿吸収体１２のホルダー１１内下流部に被着したものである。更にこの防水カバー２３の変形例として図１１に示すように、ホルダー１１を構成する下部ホルダー部材１１ｂの先端部内面に、尿吸収体１２のホルダー内下部流部の下流部端面及び左右両側面を囲う防水カバー部２４を一体形成することもある。尚、この第５実施例において、前記第１実施例，第３実施例，第４実施例の構成を併用し、過剰尿の流入吸収を更に抑制し、更にホルダー１１先端部を撥水加工又は撥水素材にて形成し、滞留尿の低減化を図るようにする。
【００１５】
【作用の説明】
過剰尿がホルダー１１内の尿吸収体１２下流部に設けた撥水加工２２部，防水カバー２３又は２４で阻止され、ホルダー１１内での流散が防止し得るので、過剰尿が試験片への直接浸透展開及び試験片への逆流が効果的に阻止され、診断片１５に対して正常の経路以外からの過剰尿が浸透展開されるのを合理的に防止し、試験片の正常反応が得られる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a portable diagnostic device capable of testing whether a woman is freely and freely pregnant, for example, without requiring a diagnosis by a specialist, and particularly to an improvement in a urine introduction part.
[0002]
TECHNICAL BACKGROUND OF THE INVENTION
There are many so-called pregnancy diagnostics on the market that test for the presence or absence of pregnancy by urinating. This type of diagnostic device is based on the principle that, when urine is applied to the tip of a urine collecting section made of a urine absorbing material, the urine is spread to the test section while penetrating, and a predetermined reaction is performed during that time.
In this pregnancy test device for infiltration of urine, sufficient amounts of urine for measurement do not reach the absorber (thus, a sufficient amount of urine is not introduced into the test section). It is instructed to insert urine in an amount (5 seconds or more) by a package insert or the like. However, this has led to an increase in the number of accidents in which the result is not displayed within a predetermined time and the measurement is finally impossible even though a sufficient amount of urine is applied. Although the causal relationship of the former accident due to insufficient urine volume can be easily estimated, it is not necessary to explain that the latter is not easy. In addition, investigation of the cause of the accident in the latter case
(1) This phenomenon occurs extremely rarely (generally occurs at a probability of once in 1,000 times),
(2) A test in which a woman applies urine directly to the device by herself.
For this reason, it was impossible to actually observe them, and it was extremely difficult to determine the cause itself. For this reason, the actual situation was that each company had no alternative but to replace the product claim with a new one. Therefore, we performed a reproduction experiment assuming all conceivable possibilities, and as a result of diligent research, we were able to find out what could occur under the following usage conditions. That is, as shown in FIG. 12, the correct usage is to hold one end of the holder 1 and apply urine with the other end of the urine absorber 2 facing downward, but as shown in FIG. It has been found that a determination accident is likely to occur when 2 is directed upward and urine is applied too much. Although the frequency of occurrence is much lower than that in the above case where the urine absorber 2 is directed upward, it also occurs when the urine absorber 2 is nearly horizontal and urine is applied too much as shown in FIG. It turned out to be gained.
Next, as a result of elucidating the phenomena that occur in these usage situations in detail, they found that the phenomena were caused by the following common phenomena. That is, when urine is applied to the tip of the urine collecting part, the urine gradually expands to the test part while absorbing and penetrating, and a predetermined reaction is performed during that time. However, urine is applied over the maximum water content of the urine absorber 2 Then, as shown in FIGS. The overflow is divided into an overflow 3 flowing on the outer surface of the urine absorber 2 and an overflow 4 flowing inside the urine absorber 2, but is not an independent flow because it is governed by gravity.
In the original usage condition, that is, when the urine absorber 2 which is the tip of the urine collecting section is directed downward, urine of the overflow naturally flows down and is discharged as it is as shown in FIG. However, when the tip is directed upward as shown in FIG. 13, most of the overflow 3 is discharged as an external flow, but part of the overflow 3 contributes to the generation of the internal overflow 4 and enters the inside of the main body, In some cases, the test section may be reached via a path other than the normal path. If this infiltrated urine comes to adhere to the test part or its end earlier than the penetration and development time to penetrate the original path and reach the test part, the penetration and development of urine from the original path will be started. It will hinder. In other words, even though a sufficient amount of urine is applied, the result that the result is not displayed within a predetermined time (usually several minutes) and the measurement cannot be finally performed is due to the urine permeation and deployment inhibition phenomenon. I was able to find out for the first time. Therefore, it became clear for the first time that this phenomenon was a common cause of accidents that could occur in any model of any manufacturer, if it was a penetration-development type test reagent.
