Sample tubes for absorbing body fluids

The innovation concerns a sample tube for absorbing body fluids with a labeling flag for attaching a marking for the identification of sample and patient »

The increasing number of clinical-chemical examinations in connection with the shortage of skilled personnel forces to do so, if possible seek to increase laboratory capacity through rationalization., i.e. to automate as many examination procedures as possible and to simplify the organization of the laboratory by the fact that the Accruing data are entered into a computer, on the one hand specifies or controls the examination process and, on the other hand, stores the resulting data and according to an entered program processed. There is an increased risk of mix-ups between sample and patient, the best too. a repetition of the examination - force. To avoid this and to accelerate the singing speed of the measurement data at the same time (on-line operation), it requires an accurate, machine-readable Identification of each individual sample.

For this purpose, it is proposed according to the innovation that the flag at the upper edge of the tube-forming retaining ring in such a way that they can be labeled with a machine-readable information pattern Areas d. <Sr flag at right angles to the axis of symmetry of the tube survive to the outside *

It is particularly advantageous if the body of the tubular row with a ring and the flag is a plastic part pressed from one piece.

In a further development of the innovation, it is proposed to arrange a day number assigned to the patient both in encrypted form and in plain text on the flag. Thereby is achieved that at each stage _s of the sample during the run, the sample can be identified by the operator.

Further details of the innovation can be found in the following exemplary embodiment.

In Fig. 1, the samples hung in a transport device * tubes shown in longitudinal view during

Fig. 2 shows the tube in plan.

The tube has a cylindrical body 1 which tapers conically downwards and at its upper edge a retaining ring 2 _S to which the flag 5 is attached. On the underside of the flag _s, which consists of a translucent material ^, a number of circular fields 4 are arranged ^ which can be filled in with opaque color by a labeling device (not shown) corresponding to the patient's day number encoded in binary code. The top of the flag is intended for the application of the day number 5 and the workplace number β in plain text. This enables a quick identification of the tube without prior decryption during the sample run. In order to make full use of the space that can be written on, the unencrypted day number 5 is applied congruently to the encrypted text 4 in a translucent color.

The tube is in the tit shown in FIG shown conveyor belt 7 so hung * that it rests with its ring 2 on the tape »Next to the tape is a photoelectric reading block 8 arranged. The light rays emanating from a light source 9 and bundled by a condenser lens 10 are from a deflection mirror 11 on a with the color of the im Day number in plain text, identically colored filter 12 steered and from the flag 5 depending on the key number inscribed partly let through, partly absorbed. Those let through Rays hit the fields below the tab

photodiodes 13 arranged identically to the flag in the reading block a congruent application of encrypted and unencrypted day number and the use of one with the color of the plain text characters with the same color filter, the plain text characters remain invisible to the photocells because of the equality of the color filter and color and therefore interfere with the removal of the encrypted Text not. The photocells are connected to a computer (not shown) that stores the data relating to the respective day number Stores measurement data and processes it according to the program entered into it.
