Description

8000662-0 2 *Användning av en återanvändbar immunoadsorbent förutsätter långtidsegenskaper, som säkerställer reproducerbarheten av 'immunoadsorben- tens verkan. Det är nödvändigt, att immunoadsorbenten' för varje försök stökiometriskt friger antigenen. Dessutom måste man säkerställa, att im- munoadsorbenten inte torkar ur och later sig packas så, att strömningsförhål- landena genom massan under immunoadsorbentens användbara livstid motsva- rar de ställda kraven. Syftet med uppfinningen är att åstadkomma en genomströmningskammare för en sådan återanvändbar immunoadsorbent, som främjar bevarandet av de för immunoadsorbenten erforderliga egenskaperna. 8000662-0 2 * The use of a reusable immunoadsorbent presupposes long-term properties which ensure the reproducibility of the action of the immunoadsorbent. It is necessary that the immunoadsorbent stoichiometrically release the antigen for each experiment. In addition, it must be ensured that the immunoadsorbent does not dry out and allow itself to be packed in such a way that the flow conditions through the mass during the useful life of the immunoadsorbent correspond to the set requirements. The object of the invention is to provide a flow-through chamber for such a reusable immunoadsorbent, which promotes the preservation of the properties required for the immunoadsorbent.

Detta syfte ernås enligt uppfinningen med en anordning enligt patentkravet l. Utföringsformer av uppfinningen är angivna i underkraven.This object is achieved according to the invention with a device according to claim 1. Embodiments of the invention are specified in the subclaims.

Föreliggande anordning användes lämpligen i en automatiskt arbe- tande anläggning för radioimmunoanalys enligt den i det föregående angivna DE-OS 24 12 833. En återanvändbar immunoadsorbent, som med fördel an- vändes i föreliggande anordning, är beskriven i stamansökningen till föreliggande avdelade ansökan 7604097-1.The present device is suitably used in an automated radioimmunoassay plant according to the aforementioned DE-OS 24 12 833. A reusable immunoadsorbent, which is advantageously used in the present device, is described in the parent application of the present assigned application. 1.

Uppfinningen belyses i det följande med bifogad ritning, som visar ett axialsnitt genom föreliggande anordning.The invention is illustrated in the following with the accompanying drawing, which shows an axial section through the present device.

Enligt ritningen uppvisar anordningen 25 ett hus 27, som har cylindrisk form för att underlätta dess framställning. I huset 27 finns en kammare 30, som innehåller immunoadsorbenten 32, som är ritat som partikelformigt material. immunoadsorbenten hálles i kammaren av en porös propp 34, vars porer är mindre än partiklarna, som bildar immunoadsorbenten.According to the drawing, the device 25 has a housing 27, which has a cylindrical shape to facilitate its manufacture. In the housing 27 there is a chamber 30, which contains the immunoadsorbent 32, which is drawn as particulate material. the immunoadsorbent is held in the chamber by a porous plug 34, the pores of which are smaller than the particles forming the immunoadsorbent.

Det finns ett utlopp 36, genom vilket ett genom -kammaren strömmande, genom inloppet 38 inkommande material åter kan lämna kammaren. Den porösa proppen 34 sitter fast i bärarkroppen, som kan bestå av polypropen eller en annan plast. Kammaren kan exempelvis ha en diameter av'3 mm och en längd av 6 mm, under det att den porösa proppen uppvisar en diameter och en längd av 3 mm och har en porvidd av 10 mikrometer. I I inloppsbanan finns filterelement 41 och 43 i form av ett nylonnät med 15,75 masker per mm, som ligger an mot en filterskiva 43, som företrädesvis består 'av polytetrafluoreten och som har formen av en filt med en porstorlek av högst ll] mikrometer. i Såsom framgår av ritningen slutar kammaren 3D i var sin ände i utvidgade ändsektioner 46 och 47 i form av försänkningar, vilka innehåller en propp 48 respektive 49. Varje propp innefattar en försänkning 51 respektive 53 och en genomgående kanal är visat på ritningen. Vid de ändar av _ proplparna, soni gränsar mot kammaren 30, har propparna en konisk öppning 56 respektive 57 och en ringformad skuldra, som upptar ett tätningselement i "sena" 8000662-0 3 form av en O-ring. O-ringarna bildar en tätning vid ändarna av försänk- ningarna i bärkroppen 27.There is an outlet 36, through which a material flowing through the chamber, entering through the inlet 38, can again leave the chamber. The porous stopper 34 is attached to the support body, which may consist of polypropylene or another plastic. The chamber may, for example, have a diameter of 3 mm and a length of 6 mm, while the porous plug has a diameter and a length of 3 mm and has a pore width of 10 micrometers. In the inlet path there are filter elements 41 and 43 in the form of a nylon mesh with 15.75 meshes per mm, which abuts against a filter disc 43, which preferably consists of polytetrafluoroethylene and which has the shape of a felt with a pore size of at most 11 micrometers. As shown in the drawing, the chamber 3D terminates at each end in enlarged end sections 46 and 47 in the form of recesses, which contain a plug 48 and 49, respectively. Each plug comprises a recess 51 and 53, respectively, and a continuous channel is shown in the drawing. At the ends of the plugs, which are adjacent to the chamber 30, the plugs have a conical opening 56 and 57, respectively, and an annular shoulder which receives a sealing element in the "late" shape of an O-ring. The O-rings form a seal at the ends of the recesses in the support body 27.

Proppen 49 tjänar till att pressa filtren 41 och 43 på plats, varvid nätet hindrar att filten tränger in i den koniska öppningen 57.The plug 49 serves to press the filters 41 and 43 into place, the net preventing the felt from penetrating into the conical opening 57.

Anslutningen av apparaten sker genom ändpropparna 48, 49 och ändförsänkningarna 51, 53. Anordningen utgör ett enhetligt element med en för det pågående försöket immunoadsorbent. När den icke användes kan den förvaras vid 4OC.The connection of the apparatus takes place through the end plugs 48, 49 and the end recesses 51, 53. The device forms a uniform element with an immunoadsorbent for the current test. When not in use, it can be stored at 4 ° C.

Anordningen uppvisar vid inloppsänden för kammaren en kon 57 för att fördela strörnningen 'över bredden av den partikelformiga immuno- adsorbenten i kammaren 30. Den koniska öppningen 56 verkar som koilektor för materialet, som lämnar kammaren, under det att proppen 48 häller den porösa proppen 34 i kammaren.The device has at the inlet end of the chamber a cone 57 for distributing the scattering over the width of the particulate immunoadsorbent in the chamber 30. The conical opening 56 acts as a coilector for the material leaving the chamber, while the plug 48 pours the porous plug 34 in the House.
