Description

Oppfinnelsen vedrører en innretning til fukting av en prøve-strinraiel med flere adskilte prøvefelt, slik de for eksempel anvendes for medisinske prøver, spesielt for undersøkelse av urin. Den er del av en linje som tjener den automatiske tilføring, sortering, fukting og innlegging av prøvestrimler i en analyseapparatur, for eksempel i et flerekanalsfoto-meter. The invention relates to a device for wetting a sample strip rail with several separate sample fields, such as are used, for example, for medical samples, especially for examination of urine. It is part of a line that serves the automatic supply, sorting, moistening and insertion of sample strips in an analysis apparatus, for example in a multi-channel photometer.

For den generelt kjente urindiagnostikk står det til disposi-sjon såkalte flerefagsurinprøvestrimler til bestemmelse av bilirubin, uroilinogen, ketonlegemer, ascorbinsyre, glukose, protein, nitritt, av pH-verdien og blod. Slike prøvestrimler inneholder flere prøvefelt, hvorpå de til den respektive prøve tilhørende reagenser er anordnet som indikator. Prøvestrimlene fuktes manuelt med urin og innlegges derefter i analysatoren. Arbeidet skal automatiseres. Hertil er det blant annet nødvendig en innretning til fukting av prøve-strimlene . For the generally known urine diagnostics, so-called multi-species urine test strips are available for the determination of bilirubin, uroilinogen, ketone bodies, ascorbic acid, glucose, protein, nitrite, the pH value and blood. Such test strips contain several test fields, on which the reagents belonging to the respective sample are arranged as an indicator. The sample strips are manually moistened with urine and then inserted into the analyzer. The work must be automated. For this, a device for wetting the test strips is needed, among other things.

Oppfinnelsen har til hensikt å forbedre den kjente teknikk og angår i henhold til dette en innretning til fukting av en prøvestrimmel med flere adskilte prøvefelt og denne innretning karakteriseres ved at det over et depot for prøve-strimmelen er anordnet en forstøvningsinnretning parallelt forskyvbar i forhold til prøvestrimmelen, og at forstøv-ningsinnretningen har en bredsliss-dyse. The invention aims to improve the known technique and accordingly relates to a device for wetting a test strip with several separate test fields and this device is characterized by the fact that above a depot for the test strip a atomizing device is arranged that can be moved parallel to the test strip , and that the atomizing device has a wide slot nozzle.

Ved stadig bevegelse av forstøvningsinnretningen over prøvefeltet er det hensiktsmessig å utstyre forstøvningsinn-retningen med minst en avsugningsinnretning for å fjerne overskytende væske mellom de enkelte prøvefelt. Ser man bort fra avsugningsinnretningen er det hensiktsmessig å utstyre forstøvningsinnretningen med et trinnverk som sørger for at dysen kommer kort tid til stillstand over hvert prøvefelt. Trinnverket kan være forbundet med en ventil som er anordnet i den væskeførende del av forstøvningsinnretningen. Oppfinnelsen forklares nærmere ved hjelp av tegningsfigurene som viser eksempelvise utførelser. In case of continuous movement of the atomization device over the test field, it is appropriate to equip the atomization device with at least one suction device to remove excess liquid between the individual test fields. Disregarding the extraction device, it is appropriate to equip the atomization device with a step mechanism that ensures that the nozzle comes to a standstill for a short time over each test field. The step mechanism can be connected to a valve which is arranged in the liquid-carrying part of the atomizing device. The invention is explained in more detail with the help of the drawings which show exemplary embodiments.

beveger seg, i sideoppriss, og moving, in side elevation, and

fig. 4 viser innretningen ifølge fig. 3, sett ovenfra. fig. 4 shows the device according to fig. 3, top view.

Ved innretningen til fukting av prøvestrimler er det over et depot 1 for prøvestrimlene 2 anordnet en forstøvningsinnret-ning 3. Forstøvningsinnretningen 3 er utstyrt med en bredslissdyse 4, og kan skyves parallelt til prøvestrimlene 2, idet dysen beveger seg over de enkelte prøvefelt 5. Ved trinnvis bevegelse av forstøvningsinnretningen ifølge fig. 1 er forstøvningsinnretningen 3 utstyrt med et trinnverk 6 som sørger for at dysen 4 kommer til å stå over et prøvefelt 5. Samtidig betjenes en ventil 7, som kan være anordnet i tilførselen for væsken. Ventilen 7 kan være mekanisk eller elektrisk forbundet med trinnverket 6. Bredslissdysen 4 er hensiktsmessig tilpasset geometrien av prøvefeltet 5, således at væske på sidene 8 av prøvefeltet 5 kan suges opp av det sugende underlag 9 for reagensbæreren 10. In the device for moistening sample strips, a atomizing device 3 is arranged above a depot 1 for the sample strips 2. The atomizing device 3 is equipped with a wide-slot nozzle 4, and can be pushed parallel to the sample strips 2, as the nozzle moves over the individual sample fields 5. stepwise movement of the atomizing device according to fig. 1, the atomizing device 3 is equipped with a step mechanism 6 which ensures that the nozzle 4 will stand above a test field 5. At the same time, a valve 7 is operated, which can be arranged in the supply for the liquid. The valve 7 can be mechanically or electrically connected to the step mechanism 6. The wide slot nozzle 4 is suitably adapted to the geometry of the sample field 5, so that liquid on the sides 8 of the sample field 5 can be sucked up by the absorbent substrate 9 for the reagent carrier 10.

Ved stadig føring over prøvefeltet 5 må det sørges for at overskytende væske mellom de enkelte prøvefelt fjernes. Hertil kan forstøvningsinnretningen være utstyrt med minst en avsugningsinnretning 11. Ifølge fig. 4 er det anordnet to avsugningsinnretninger 11. Prøvestrimlene består vanligvis av en bærer 12, prøvefeltene 5 og et nettaktig dekke til beskyttelse av prøvefeltet, idet sideområdene 8 av prøvefel-tet forblir ubeskyttet. Preøvefeltene 5 kan bestå av et sugende underlag 9 for reagensbæreren og reagensbæreren 10 eller av en enlags reagensbærer som er påklebet på en bærefolie. When constantly guiding over the test field 5, it must be ensured that excess liquid between the individual test fields is removed. In addition, the atomizing device can be equipped with at least one suction device 11. According to fig. 4 two suction devices 11 are arranged. The sample strips usually consist of a carrier 12, the sample fields 5 and a net-like cover to protect the sample field, the side areas 8 of the sample field remaining unprotected. The test fields 5 can consist of an absorbent substrate 9 for the reagent carrier and the reagent carrier 10 or of a single-layer reagent carrier that is glued to a carrier foil.
