Abstract
The novel safety blood withdrawal device includes as principal components a syringe body (SK) with a cannula holder, a collecting container (AB) which can be pressed into the syringe body, and a continuous tube (R). The collecting container is present in the form of a hollow cylinder (11) with a forwardly fitted, fixed sealing plug (12) of elastic material and with an internally fitted sealing piston (13), which is movable relative to the piston inner wall. The syringe body exhibits at its rear end gripping lugs (21) and at the end face (22) a cannula holder (23). The continuous tube is mounted by means of a closing piece (31) in a closure block (32) to be movable in the direction of the longitudinal axis of the device, the closure block (32) being tightly secured at the front sealing surface (22) and creating a liquid-conducting connection between the interior space of the cannula and the interior cavity (33) of the closure block (32), and the closing piece (31) tightly fixed to the continuous tube, in the event of pressure on the tube in the direction of the tip of the device, creating a liquid-conducting connection between the interior space of the tube and the interior cavity (33), and, in the event of tension on the continuous tube, sealing this connection in a liquid-tight manner. The novel device is used, advantageously as a set, for the withdrawal of blood from humans.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
