Die vorliegende Erfindung betrifft eine Ausführungsart der durch das Patent Nr. 84901 geschützten zerlegbaren Spritze. Anstatt eines auf einer Seite offenen Metallschutzmantels ist ein geschlossener, seitlich ausgesparter Schutzmantel ohne Böden verwendet. In diesen Schutzmantel wird die Glasröhre gesteckt und durch über beide Enden des Schutzmantels gesteckte Deckel, die anstatt mittelst Gewinde durch schraubenförmig verlaufende, in Haken des Schutzmantels eingreifende Verschlufsleisten an ersterem festgehalten und abgedichtet werden. Zum Zerlegen der Spritze bedarf es nur einer Vierteldrehung der beiden Deckel, worauf alle Theile bequem aus einander genommen werden können.The present invention relates to one embodiment the dismountable syringe protected by patent no. 84901. Instead of one on one side of the open metal protective sheath is a closed protective sheath recessed at the side used without bottoms. The glass tube is inserted into this protective jacket and through both ends of the protective jacket plugged-in lids, which instead of being threaded through screw-shaped hooks of the protective jacket engaging locking strips are held on the former and sealed. To dismantle the syringe, you only need a quarter turn of the two lids, whereupon all parts can easily be taken apart.
In der Zeichnung ist die neue Ausführungsart der Spritze in Fig. 1 und 2 in Ansicht und Längenschnitt dargestellt; die Fig. 3 bis 12 zeigen verschiedene Ansichten und Schnitte des geschlossenen Metallmantels A und der beiden, lösbar daran festgehaltenen Deckel D und B. In the drawing, the new embodiment of the syringe is shown in Fig. 1 and 2 in view and longitudinal section; 3 to 12 show different views and sections of the closed metal jacket A and the two covers D and B releasably held thereon.
Am geschlossenen Metallmantel A sind an beiden Enden je ein Paar hakenartige, am einen Ende zu Griffen ausgebildete Ansätze a2 und al angebracht, welche die je halb um den Mantel herumlaufenden, schraubenförmig ansteigenden Leisten b und d der beiden Deckel B und D übergreifen. Zwischen zwei Rundleisten befinden sich an diametralen Stellen Aussparungen, an welchen die Deckel über die Ansätze a2 und a1 gesteckt werden können. Durch Drehen der Deckel wird der eine Deckel gegen das untere, der andere gegen das obere Ende des Cylinders E angedrückt. Der untere Deckel B dichtet mittelst der Dichtscheibe oder unmittelbar am Cylinder ab. Zum Abdichten des oberen Deckels am Cylinder wird stets eine Dichtscheibe e verwendet, die auch noch den Zweck erfüllt, den Kolben C abzudichten.At both ends of the closed metal jacket A , a pair of hook-like lugs a 2 and a l are attached at one end, which are designed as handles and which overlap the helically rising strips b and d of the two covers B and D , which run halfway around the jacket. There are cutouts at diametrical points between two round strips, into which the cover can be inserted over the shoulders a 2 and a 1. By turning the cover, one cover is pressed against the lower and the other against the upper end of the cylinder E. The lower cover B seals by means of the sealing washer or directly on the cylinder. To seal the upper cover on the cylinder, a sealing washer e is always used, which also serves the purpose of sealing the piston C.
Der untere Deckel B ist aufsen verengt und innen leicht kegelig erweitert, so dafs der Nadeleinsatz L durch einfaches Einstecken in den Deckel darin abdichtet und genügend festgehalten wird.The lower cover B is narrowed on the outside and widened slightly conically on the inside, so that the needle insert L is sealed and adequately held in place by simply plugging it into the cover.
Wenn eine Zerlegbarkeit der Spritze am unteren Theil der Metallhülse A nicht gewünscht wird, kann der Deckel B weggelassen und die Metallhülse A unten verjüngt und daselbst innen wieder etwas kegelig zum unmittelbaren Einstecken des Nadeleinsatzes L hergestellt werden.If it is not desired to dismantle the syringe at the lower part of the metal sleeve A , the cover B can be omitted and the metal sleeve A tapered at the bottom and made somewhat conical on the inside for the immediate insertion of the needle insert L.
Anstatt dafs die Deckel B und D die Hülse A übergreifen, können diese auch in der letzteren liegend, gewünschtenfalls auch als flache Scheiben angeordnet sein.Instead of the covers B and D overlapping the sleeve A , they can also be arranged lying in the latter, if desired also as flat disks.
Ebenso kann man die hakenartigen Ansätze al und a2 anstatt an der Hülse A anYou can also use the hook-like approaches a l and a 2 instead of the sleeve A.
Claims (1)
Eine Ausführungsform der unter 1. dargestellten zerlegbaren Spritze in der Weise, dafs der untere abnehmbare Deckel (B) weggelassen und an seiner Stelle die Metallhülse (A) unten verlängert, verjüngt und im Innern des verjüngten Theils kegelig gestaltet ist.ι. A dismountable syringe of the type protected by patent no. 84901, characterized in that instead of the metal jacket of the main patent which is open at one end, a closed metal jacket (A) is used, in which the syringe barrel (E) by means of two over both ends of the Covered cover (B) and (D), through whose helical strips (b) and (d) running diametrically in a semicircle around the cover with left and right-hand threads in hook-like attachments (a 2 ) and (a 1 ) of the cover (A ) is held and sealed by axial pressure, whereby an outwardly tapered sleeve (B) can also be made slightly conical in its thinner extension (Fig. 9), so that the needle salt (L) of the syringe is simply inserted into this cover ( B) is sealed and held in it.
An embodiment of the dismountable syringe shown under 1. in such a way that the lower removable cover (B) is omitted and in its place the metal sleeve (A) is lengthened, tapered and tapered inside the tapered part.
