Problems solved by technology

This or other measures have the disadvantage that the color emergency coding of the sample vials cannot be as urgent as it is required especially when placed in a common rack with a large number of sample vials that are not marked as emergency so clearly identified
Because the labeled sample vials are just as indistinguishable in the rack as the film caps, since the film caps are only inserted into the fixed stops of the housing and thus provide only a small area of ​​signal function
In addition, sample vials marked with colored film caps are easy to adapt directly for analysis, but the sampling needle inserted into the sample vial must first pass through the film of the cap and, on the other hand, pass through the closure cap The film of the cover
The application of force required for this (since a large resistance has to be overcome) can lead to damage to the membrane cover

Embodiment Construction

[0011] exist figure 1 and 2 , a cylindrical sample tube 1 of a blood collection device is shown on an enlarged scale, in which a gas-tight piston rod 2 with a piston is displaceably arranged. The sample vial 1 is closed at its front end by a screw-on closure cap 3 in the present exemplary embodiment. From this closing cap axially protrudes the cover body 4, which, for locking, passes through a needle or double needle, not shown, with a fixed stop 5 (see figure 2 ) guide sleeve composition. A membrane or plug (not shown) is arranged in the conical dome 6 .

[0012] In order to identify the sample vial 1 as an emergency, a signal color ring 7 , for example of a luminescent color, is inserted on the cover 4 as an identifier. This signaling color ring is likewise produced in one piece by plastic injection molding and has a sleeve end section 8 which is larger in diameter than the cap and a head section 9 which tapers upwards. When inserting the signal color ring 7 onto the c...

Abstract

A specimen tube for receiving bodily fluids, particularly blood, has a sealing cap having a tip with a pierceable membrane, stopper or similar device, at its end. A guide sleeve can be placed on the tip and carries a single or double needle. The tube can also be provided with an emergency indicator that is configured as an emergency signal colored ring surrounding the tip but leaving free access from outside to the pierceable element at the end of the tip.

Description

technical field [0001] The invention relates to a sample vial for containing body fluids, especially blood, with a closure cap having a cover with a pierceable membrane arranged inside the cap for insertion Introducer sleeves for carrying needles and twin needles to the shield, and the sample vials can be equipped with colored emergency markers. Background technique [0002] In the blood collection device known from DE 30 49 503 C, the cap, which closes the collection tube at its front end, has a cylindrical, axially protruding cap. The cover is closed at its front end by a pierceable closure plug / film which rests against the end plate of the cover with a central hole and is edged by the cover at the front end. The flange is fixed. The closure cap is preferably screwed on or inserted onto the sample vial. The tubular guide sleeve carries a double-ended needle with cutting edges on its front end in the holder, the end protruding from the guide sleeve for introduction into ...
