PRØVEHOLDERSAMPLE HOLDER
Det er kjent å anvende prøveholdere som har,anordnet prøvemotta-gende ark mellom et frontpanel.og et bakpanel, som begge er forsynt med en åpning og som har' dreibare dekkanordninger for å It is known to use sample holders which have arranged sample-receiving sheets between a front panel and a back panel, both of which are provided with an opening and which have rotatable cover devices to
dekke disse åpninger. Typisk for det tilfellet hvor man skal be-stemme okulert blod i avføring er det prøvemottagende ark papir som er impregnert med "guaiac" og en fremkalleroppløsning såsom en peroksydoppløsning påføres gjennom åpningen i bakpanelet. cover these openings. Typically for the case where occult blood in stool is to be determined, the sample-receiving sheet of paper is impregnated with "guaiac" and a developer solution such as a peroxide solution is applied through the opening in the back panel.
Ofte er det meget ønskelig å ha to eller flere prøver for å kunne sammenligne disse ved siden av hverandre ved den aktuelle under-søkelse. F.eks. er det ønskelig å undersøke mere enn en del.av avføringsprøven når denne skal undersøkes med hensyn til okulert blod. Til tider kan det være ønskelig å undersøke en prøve "med meré enn en prøvemetode, eksempelvis kan en avføringsprøve under-søkes både i henhold til "guaiåc"prøven og orto-tolidinprøven som har forskjellig følsomhet og er nyttig ved diagnostisering med hensyn til okulert blod. Med foreliggende oppfinnelse opp-nås disse hensikter. It is often very desirable to have two or more samples in order to be able to compare them side by side during the examination in question. E.g. is it desirable to examine more than one part of the stool sample when this is to be examined with regard to occult blood. At times, it may be desirable to examine a sample with more than one test method, for example a stool sample can be examined both according to the "guaiac" test and the ortho-tolidine test, which have different sensitivities and are useful in diagnosing with regard to occult blood With the present invention, these purposes are achieved.
Ved oppfinnelsen muliggjøres en side-ved-side sammenligning med de samme og forskjellige prøvereagenser ved å tilveiebringe et antall åpninger i front- og bakpanelene med anordninger for å dekke disse påninger. Fortrinnsvis er det anordnet barriere-anordninger' for å forhindre migrering fra en prøveporsjon på holderen til en annen prøveporsjon. Et helt ark som ligger under alle åpningene kan være forsynt med et prøvéreagens eller arket kan være forsynt med like eller forskjellige prøvereagenser kun på utvalgte steder motstående til de åpninger hvor reagenset på-føres, eksempelvis ved trykning. Separate ark kan også anvendes The invention enables a side-by-side comparison with the same and different sample reagents by providing a number of openings in the front and back panels with devices to cover these openings. Preferably, barrier devices are provided to prevent migration from one sample portion on the holder to another sample portion. An entire sheet that lies under all the openings can be provided with a sample reagent or the sheet can be provided with the same or different sample reagents only in selected places opposite the openings where the reagent is applied, for example when printing. Separate sheets can also be used
under åpningene og de samme eller forskjellige prøvereagenser under the openings and the same or different sample reagents
-anvendes på arket og påføres eksempelvis ved trykning.- is used on the sheet and applied, for example, when printing.
Fig. :1 viser et grunnriss av et delvis bearbeidet ark for fremstilling, av en'holder i henhold til oppfinnelsen. Fig. 2 er et sideriss, sett forfra, av en holder fremstilt fra arket ifølge fig. 1, med frontdekslet- åpent. Fig. 3 ér et riss sett fra den motsatte side av holderen ifølge fig. 2 med frontdekslet lukket. Fig. 4 er et snitt, delvis gjennomskåret, av et modifisert ark for fremstilling av en holder, og Fig. 1 shows a plan view of a partially processed sheet for the manufacture of a holder according to the invention. Fig. 2 is a side view, seen from the front, of a holder made from the sheet according to fig. 1, with the front cover open. Fig. 3 is a view seen from the opposite side of the holder according to fig. 2 with the front cover closed. Fig. 4 is a section, partially cut through, of a modified sheet for the manufacture of a holder, and
fig. 5 er et delvis gjennomskåret riss av et annet, modifisert ark for fremstilling av en holder hvor det anvendes separate ark. fig. 5 is a partially cross-sectional view of another, modified sheet for the manufacture of a holder where separate sheets are used.
Et ark 2, eksempelvis fremstilt fra papir eller kartong har et frontpanel 4, et bakpanel 6 og et deksel 8. Arket 2 er falset mellom panelene 4 og 6 langs linjen indikert ved 10 for å fremme bretting. En fals langs^ linjen ved 12 mellom panelet 6 og dekslet 8 fremmer hengsling av dekslet 8. Dekslet 8 er forsynt med et fremspring 14 egnet for gjennomføring gjennom en sirkulær slisse 16 i panelet 4 og en sirkulær slisse 18 i panelet 6 for å fastlåse dekslet i en.lukket stilling. A sheet 2, for example made from paper or cardboard has a front panel 4, a back panel 6 and a cover 8. The sheet 2 is folded between the panels 4 and 6 along the line indicated at 10 to promote folding. A fold along the line at 12 between the panel 6 and the cover 8 facilitates hingeing of the cover 8. The cover 8 is provided with a projection 14 suitable for passing through a circular slot 16 in the panel 4 and a circular slot 18 in the panel 6 to lock the cover in a closed position.
Frontpanelet 4 er forsynt med et par ved siden av hverandre liggende åpninger 22 og 24. Et ark av absorberende papir 26, eksempelvis et filterpapir ligger over (slik det sees i fig. 1) åpningene 22 og 24. Arket 26 er impregnert med et reagens såsom "guaiac".. En barriere 28 i den sentrale del av arket 26 forhindrer migrering av prøven eller fremkallingsoppløsningen mellom de to halvdeler av arket 26. Barrieren 28 kan være et-hvert materiale som impregnerer papiret 26 og som vil forhindre migrering, eksempelvis lim, en voks eller en syntetisk harpiks såsom en epoksy-, fénol-, polyester- eller silikonharpiks som vanlig anvendes i papir-harpikslaminater. Som vist på tegningen er barrieren 28 dannet av lim som også er avsatt på frontpanelet 24 indikert ved 32 og på bakpanelet 6 som indikert ved 34 i den hensikt å feste arket 26 både til panelene 4 og 6. Panelene 4 og . 6 heftes sammen ved hjelp av et klebemiddel såsom lim indikert ved 35. The front panel 4 is provided with a pair of side-by-side openings 22 and 24. A sheet of absorbent paper 26, for example a filter paper, lies above (as seen in Fig. 1) the openings 22 and 24. The sheet 26 is impregnated with a reagent such as "guaiac".. A barrier 28 in the central part of the sheet 26 prevents the migration of the sample or developing solution between the two halves of the sheet 26. The barrier 28 can be any material which impregnates the paper 26 and which will prevent migration, for example glue , a wax or a synthetic resin such as an epoxy, phenolic, polyester or silicone resin commonly used in paper-resin laminates. As shown in the drawing, the barrier 28 is formed by glue which is also deposited on the front panel 24 indicated at 32 and on the rear panel 6 as indicated at 34 for the purpose of attaching the sheet 26 to both panels 4 and 6. Panels 4 and . 6 are joined together by means of an adhesive such as glue indicated at 35.
For påføring av fremkallingsoppløsningen, eksempelvis en peroksyd-oppløsning er bakpanelet 6 forsynt med fremspring 38 og 40 henholdsvis motstående åpningene 22 og 24. Perforeringer 42 er anordnet for å gjøre det mulig å fjerne fremspringene 38 og 40 vekk fra arket 26 ved at disse henholdsvis dreies om falselin-jene 44 og 46. For applying the developing solution, for example a peroxide solution, the back panel 6 is provided with protrusions 38 and 40, respectively opposite openings 22 and 24. Perforations 42 are arranged to make it possible to remove the protrusions 38 and 40 away from the sheet 26 by turning these respectively about fold lines 44 and 46.
For å forme den fullstendige holder 50, vist i fig. 2, brettes arket 2 langs falselinjen 10 for å bringe panelene 4 og 6 sammen og disse holdes prinsipielt sammen ved hjelp av limet 35. Dekslet 8 bøyes rundt falsen 12 og festes til panelet 4 ved hjelp To form the complete holder 50, shown in FIG. 2, the sheet 2 is folded along the fold line 10 to bring the panels 4 and 6 together and these are basically held together using the glue 35. The cover 8 is bent around the fold 12 and attached to the panel 4 using
av en limdråpe 52.of a glue drop 52.
For å, anvende holderen separerer pasienten dekslet 8 fra panelet 4. ved punktet 52, åpner dekslet og påfører ved en applikator et tynt lag av én prøve av en del av sin avføring på papiret To use the holder, the patient separates the cover 8 from the panel 4. at point 52, opens the cover and applies with an applicator a thin layer of one sample of a part of his stool on the paper
26 gjennom åpningen 22. Deretter påfører han fra en annen del av avføringen et tynt lag på papiret 26 gjennom åpningen 24. Deretter lukker han dekslet og låser fremspringet 14 i åpningene 16 og 18 og returnerer prøveholderen til sin lege. Når legen mottar holderen trekker han tungene 38 og 40 fri fra bakpanelet 6 og åpner dem utover. Gjennom de således dannede åpninger kan legen påføre en peroksydoppløsning på det "guaiac"impregnerte papir 26 på. motsatt side av hver av åpningene 22 og 24 og ob-servere forsøksresultatene, eksempelvis for prøven méd hensyn på okulert blod graden av fremkalt blåfarge. Dette tilveiebrin-ger en god side-ved-side sammenligning av forsøksresultatene fra to forskjellige porsjoner av pasientens avføring. Som vist i fig. 4 er arket 2 for fremstilling av en holder i henhold til oppfinnelsen festet til denne istedenfor arket 26 et ark 62 av papir forsynt med en sentral limbarriere 64. Arket 62 adskiller seg fra arket 26 ved at det istedenfor å være gjennomimpregnert med et reagens er det på motsatt side. av åpningen 22 påtrykt et reagens 66 og på den motsatte side av .åpningen 24 påtrykt et annet forskjellig reagens 68. Reagen— 26 through the opening 22. Then, from another part of the stool, he applies a thin layer to the paper 26 through the opening 24. He then closes the cover and locks the projection 14 in the openings 16 and 18 and returns the sample holder to his doctor. When the doctor receives the holder, he pulls the tongues 38 and 40 free from the back panel 6 and opens them outwards. Through the openings thus formed, the doctor can apply a peroxide solution to the "guaiac" impregnated paper 26. opposite side of each of the openings 22 and 24 and observe the test results, for example for the sample with consideration on eyed blood the degree of induced blue color. This provides a good side-by-side comparison of the test results from two different portions of the patient's stool. As shown in fig. 4, the sheet 2 for the production of a holder according to the invention is attached to this instead of the sheet 26 a sheet 62 of paper provided with a central adhesive barrier 64. The sheet 62 differs from the sheet 26 in that instead of being impregnated with a reagent, it is on the other side. of the opening 22 a reagent 66 is imprinted and on the opposite side of the opening 24 another different reagent 68 is imprinted. Reagent—
set 66,kan eksempelvis være "guaiac" og reagenset 68 kan eksempelvis være o-tolidin. Ved bruk kan reagensene 66 og 68 fremkalles med et peroksyd eller en organisk peroksydoppløsning. set 66 can, for example, be "guaiac" and the reagent 68 can, for example, be o-tolidine. When used, reagents 66 and 68 can be developed with a peroxide or an organic peroxide solution.
Som vist i fig. 5 har et ark 2 for anvendelse ved fremstilling av en holder i henhold til oppfinnelsen et separat ark 72 motstående åpningen 22 og ét separat ark 74 motstående åpningen-24. Arket 22 kan eksempelvis være impregnert med "guaiac" og arket 74 eksempelvis méd o-tolidin. Arket 72 er impregnert med en epoksyharpiks som indikert ved 76 som virker som en barriere og fester arket 72 både til front- og bakpanelene. På tilsvarende måte er arket 74 impregnert med en epoksyharpiks ved 78 som fester arket 74 både til front- og bakpanelene. As shown in fig. 5, a sheet 2 for use in the manufacture of a holder according to the invention has a separate sheet 72 opposite the opening 22 and a separate sheet 74 opposite the opening 24. Sheet 22 can, for example, be impregnated with "guaiac" and sheet 74, for example, with o-tolidine. The sheet 72 is impregnated with an epoxy resin as indicated at 76 which acts as a barrier and attaches the sheet 72 to both the front and back panels. Similarly, the sheet 74 is impregnated with an epoxy resin at 78 which attaches the sheet 74 to both the front and back panels.
