Description
15 20 25 30 35 szoosåv-sei 2 kanyl. Från huset sträcker sig en stutš 3 för_injice- ring av ett medicinskt sekundärfluidum i genomloppet 2 och således i patienten tillsammans med primärfluidet. 15 20 25 30 35 szoosåv-sei 2 cannula. Extending from the housing is a socket 3 for injecting a medical secondary fluid into the passage 2 and thus into the patient together with the primary fluid.
Injiceringen sker med hjälp av en spruta, för vilket ändamål stutsen har ett koniskt utrymme 4 förupptagande av injektionssprutas vanligen koniska sprutände, och en kanal 5, som mynnar i genomloppet 2. Ett av elastiskt material, såsom gummi, bestående cirkulärt rörstycke 6 har ventilfunktion och är anordnat att genom.denna kanal 5 medge injiceringen under inverkan av ett förut- bestämt injiceringstryck och att.blockera för strömning från genomloppet 2 till och genom kanalen 5. Rörstycket 6 är anordnat i en urtagning 5a i ett separat, i stut- sen 3 utifrân med snäv passning infört ventilhus 3a, vilken-urtagning bildar ventilsäte och likt en fattning med snäv passning griper och håller rörstycket 6 över väsentligen hela dettas längd och över mer än hälften av dettas omkrets så, att fattningens vid ändarna öppna slitsöppning 5b är vänd mot kanalens 5 mynning 5c i genomloppet 2. Från fattningens Sa i förhållande till slitsöppningens 5b motsatta del sträcker sig en smal cirkulär kanaldel Sd till det i ventilhuset 3a utfor- made koniska utrymmet 4. Detta kan vara förslutbart me- delst ett icke visat konventionellt snäpplock.The injection is made by means of a syringe, for which purpose the nozzle has a conical space 4 for receiving the usually conical syringe end of the syringe, and a channel 5, which opens into the passage 2. One of elastic material, such as rubber, consisting of circular pipe section 6 has valve function and is arranged to allow the injection through this channel 5 under the influence of a predetermined injection pressure and to block flow from the passage 2 to and through the channel 5. The pipe piece 6 is arranged in a recess 5a in a separate, in the nozzle 3 valve housing 3a inserted from outside with a tight fit, which recess forms a valve seat and, like a tight fit socket, grips and holds the pipe piece 6 over substantially its entire length and over more than half of its circumference so that the slit opening 5b of the socket is open towards the mouth 5c of the channel 5 in the passage 2. A narrow circular channel part Sd extends from the socket 5 in relation to the opposite part of the slot opening 5b. to the conical space 4 formed in the valve housing 3a. This can be closable by means of a conventional snap cap (not shown).
Vid injicering av fluidum i genomloppet 2 via stut- sen 3 inpressar fluidet rörstyckets 6 vägg mittför den smala kanaldelen Sd och finner detta fluidum sin väg till genomloppet 2 genom kanalens 5 sektioner 5d, Sa, sb och se. Å ' e Framställningen av den beskrivna injektionsanord- ningen är mycket enkel i det att huset l med den ven- tilhuset 3a upptagande, i ett stycke med huset l ut- förda stutsdelen 3b och ventilhuset 3a framställes separat t ex genom formpressning i plast, varpå det ventilbildande rörstycket 6 intryckes i ventilhuset 3a genom slitsöppningen Sb. Därefter införes ventilen 6, 7 i stutsdelen 3a. Monteringen erfordrar ingen juste- 8200347-6 3 ring, så att såväl framställningen som monteringen kan ske i en automatiserad, in line procedur.When injecting fluid into the passage 2 via the nozzle 3, the fluid presses the wall of the pipe piece 6 opposite the narrow channel part Sd and this fluid finds its way to the passage 2 through the sections 5d, Sa, sb and se of the channel 5. The production of the described injection device is very simple in that the housing 1 with the valve part 3b receiving the valve housing 3a integral with the housing 1 and the valve housing 3a is manufactured separately, for example by molding in plastic, whereupon the valve-forming pipe piece 6 is pressed into the valve housing 3a through the slot opening Sb. Then the valve 6, 7 is inserted into the nozzle part 3a. The assembly does not require any adjustment, so that both the manufacture and the assembly can take place in an automated, in line procedure.
Stutsen 3 kan naturligtvis vara formad i ett stycke och på något lämpligt sätt, t ex medelst ett skruvför- band, förbindas med genomloppets begränsningsvägg.The socket 3 can of course be formed in one piece and in some suitable way, for example by means of a screw connection, connected to the boundary wall of the passage.
Rörventilen 6 kan vara vriden 900 i förhållande till det visade läget.The pipe valve 6 can be turned 900 in relation to the position shown.
