3. Apparatus as in claim 1, wherein said auxiliary outlet is opposite said blood outlet.
4. Apparatus as in claim 1, further comprising a valve connected to said auxiliary port and pre-connected and sterilized together with said blood purifier.
5. Apparatus as in claim 1, further comprising a multi-way stopcock valve connected to said auxiliary port and pre-connected and sterilized together with said blood purifier.
6. Apparatus as in claim 1, further comprising a multi-way stopcock valve connectable to said auxiliary port and a syringe connectable to said multi-way valve, said valve, syringe, and said blood purifier forming a kit.
7. Apparatus as in claim 1, further comprising a holder, said blood purifier having a longitudinal axis and said holder being configured to support said blood purifier with said longitudinal axis at an angle with respect to the vertical, as defined with respect to the force of gravity.
8. Apparatus as in claim 1, further comprising a gas release component connected to said auxiliary port and pre-connected and sterilized together with said blood purifier, said air release component being configured to permit gas to egress from said header space without permitting blood to egress from said header space.
9. Apparatus as in claim 8, wherein said air release component includes a hydrophobic membrane.
10. A blood treatment apparatus, comprising:
a blood purifier including filter media into which blood comes in contact during use;
said processing element having a header chamber at a position where blood exits a portion of said blood purifier, said header chamber having at least one blood outlet and one auxiliary outlet remote from said at least one blood outlet;
said auxiliary outlet being configured to permit the removal of gas accumulated in said header chamber and addition and removal of medicament.
11. Apparatus as in claim 10, further comprising a valve connected to said auxiliary port and pre-connected and sterilized together with said blood purifier.
12. Apparatus as in claim 10, further comprising a multi-way valve connected to said auxiliary port and pre-connected and sterilized together with said blood purifier.
13. Apparatus as in claim 10, further comprising a syringe connected to said auxiliary port.
14. Apparatus as in claim 10, further comprising a holder configured to orient said blood purifier such that said at least one blood outlet is lower, with respect to a direction of gravity, than said auxiliary outlet.
15. Apparatus as in claim 10, further comprising a gas release component connected to said auxiliary port and pre-connected and sterilized together with said blood purifier, said air release component being configured to permit gas to egress from said header space without permitting blood to egress from said header space.
16. Apparatus as in claim 15, wherein said air release component includes a hydrophobic membrane.
17. A blood treatment apparatus, comprising:
a blood purifier including microtubular filter membranes in a bundle with one end of said bundle terminating in a first manifold at a lower end of said blood purifier and a second end of said bundle terminating in a second manifold, blood flowing in an upward direction through said filter media during use;
said purifier having first and second header chambers forming respective passages where flow divides and coalesces in said first and second manifolds, respectively;
said second header having an outlet where a coalesced flow from said second manifold flows out of said second header;
said purifier being of generally cylindrical construction with a longitudinal axis parallel to said microtubular membranes;
said second header having an auxiliary port having fitted with a gas release membrane to allow any gas bubbles in blood in said second header to flow out of the auxiliary port;
a holder configured to hold said purifier in a preferred orientation in which said longitudinal axis forms an angle with respect to a direction of gravitation force and with said auxiliary port at a highest point of said second header and said outlet being positioned remote from
said port, said highest point being determined with respect to said preferred orientation;
said holder and a body of said purifier having mechanical features that prevent engagement of said purifier in said holder unless said purifier is in said preferred orientation with respect to said holder, thereby ensuring said purifier is used in said preferred orientation;
said holder being fixedly mountable on a blood processing machine or some other base of reference in a fixed orientation.
The claims below are in addition to those above.

7. A method for checking a bore hole, comprising:
introducing the bore hole in a workpiece by laser pulses;
receiving characteristic signals from a region of the bore hole by a sensor;
comparing characteristic signals received within a characteristic time interval following a laser pulse to setpoint values, the characteristic time interval defined as a function of material properties of the workpiece and as a function of process parameters of the laser pulse, the characteristic time interval beginning at an earliest as soon as at least a thin skin of a bore wall has solidified after melting by a preceding laser pulse and ending at a latest as soon as a new laser pulse occurs.
8. The method according to claim 7, wherein the characteristic time interval begins as soon as an entire melted material has solidified, a length of the characteristic time interval selected such that a sufficient quantity of signal data is receivable in the receiving step.
9. The method according to claim 7, wherein the characteristic signals are received in the receiving step by at least one of (a) a CCD camera and (b) a CMOS camera.
10. The method according to claim 7, further comprising emitting at least one of (a) an optical and (b) a thermal measuring signal in a direction of the region of the bore hole starting with the beginning of the characteristic time interval.
11. The method according to claim 10, wherein the measuring signal is emitted in the emitting step by a drilling laser.
