Definitions
- the present invention relates to a centrifuge according to the preamble of claim 1 and a method for operating the centrifuge according to the preamble of claim 12.
- a generic centrifuge is known from US 5,328,441.
- the liquid is first drained from the centrifuge drum and then the solid is peeled out of the centrifuge drum by means of a device specially designed for this purpose.
- the solids are collected underneath the centrifuge drum in an undetectable way.
- a centrifuge of the type described above is used in the pharmaceutical sector, for example for the extraction of solids from human blood and or for the production of insulin
- handling appears problematic in view of the increasingly stringent hygiene requirements in recent times.
- manual handling of the solids discharge leads to losses, which reduces the yield of the solids extraction.
- solids are obtained from blood, there is a particularly high level of interest in the loss-free solids extraction.
- the invention aims to provide a centrifuge and a method for operating the centrifuge with which a largely loss-free extraction of solids from a centrifugal material such as blood can be achieved with an increased hygiene standard.
- the invention achieves this aim with regard to the centrifuge by the subject matter of claim 1 and with regard to the method for operating the centrifuge by the subject matter of claim 12.
- the invention is characterized in that a container is provided for collecting part of the constituents released by the centrifuge, in particular the solid, a bag for holding the solids from the centrifuge drum being inserted into the container .
- a container is provided for collecting part of the constituents released by the centrifuge, in particular the solid, a bag for holding the solids from the centrifuge drum being inserted into the container .
- the interior of the bag is preferably connected to the space surrounding the bag via a pressure-equalizing hose and / or pipeline, which preferably opens into the interior of the bag in the vicinity of the axis of rotation of the centrifuge drum.
- a pressure-equalizing hose and / or pipeline which preferably opens into the interior of the bag in the vicinity of the axis of rotation of the centrifuge drum.
- the air surrounding the drum also rotates due to the friction surfaces of the drum. This rotation creates an increase in pressure from the inside (axis of rotation) to the outside due to the centrifugal forces.
- the space in the inner region - that is, in the region of the axis of rotation - is connected to the ambient pressure, an overpressure occurs in the outer region of the interior of the bag.
- the bag is "stretched” and pressed against the surrounding walls, so that it is particularly problem-free Filling the bag is possible.
- the hose or pipeline is preferably guided from the interior of the bag into the space between the exterior of the bag and the inner wall of the container. If the pressure in the container is reduced during spinning in order to carry out the spinning process in a vacuum, the pressure drop created by the rotation of the drum is sufficient to open the bag. The low pressure also facilitates the sterile handling of the centrifuge.
- the hose or pipeline is provided with a shut-off valve.
- the valve is closed in order to prevent the solids from coming into contact with the ambient air when the pressure in the container increases after a spinning process.
- Figure 1 is a schematic, partially sectioned view of a centrifuge according to the invention.
- FIG. 2 shows a partially sectioned view of a further centrifuge according to the invention in the operating position changed compared to FIG. 1 when welding a bag filled with solid matter.
- FIG. 1 shows a centrifuge 1 with a housing 3, on which the drive unit 5 of a centrifuge drum 7 is arranged.
- Lines 9 enable a centrifugal material such as blood to be fed into and removed from the centrifuge drum 7, which is to be separated into the liquid and solid components therein.
- the centrifuge drum 7 projects into a container 11 which is arranged on the underside of the housing 3 and which has a cylindrical container section 13 which is closed at the bottom in a cup-like manner and can be attached to an upper container closure 15 in a pressure-tight manner.
- the container end 15 has a stepped ring 17, on the outer wall of which, when the container 11 is closed, the inner wall of the opening area of the cup-like container section 13 rests, with the stepped ring 17 and the undersidenic container section 13, a sealing ring 19 is arranged.
- the container end 15 is completed by a sealing ring 21 located inside the ring -17 with an inflatable sealing chamber 23 which, when inflated, bears against the inner wall of the stepped ring 17 and by an insert ring 25 for the sealing ring 21 located on the inner wall
- the centrifugal material is produced for the separator drum by a pipeline 26 which runs through the lower wall of the housing 3a.
- the space enclosed by the lower and upper container sections 13, 15 can be evacuated with the aid of a pump (not shown here) so that the actual spinning process can take place under negative pressure.
- a cylindrical jacket 27 which extends to near the bottom of the container section 13, which essentially runs parallel to the outer wall of the container section 13 and is formed with a double wall 27a, 27b, between the A space 29 through which rinsing liquid can flow is formed in the walls 27a and 27b and can be supplied via a feed line 31 and a discharge line (not shown here) can be derived.
- a film-like plastic tube 33 which lies above the sealing ring 21 in a ring-like receiving space 35 and from there down into the container section 13 can be pulled.
- the lower container section 13 is first lowered using a suitable lifting device (not shown here) (see FIG. 2), the plastic tube 33 being pulled downward out of the receiving space 35. Then the plastic tube 33 is underneath the jacket 27 and above the container Section 13 pressed together and welded in two closely adjacent areas, for example line-like (arrows a and b), so that a lower seal for an upper plastic bag a and an upper seal for a lower bag 37b is formed. The two bags 37a and 37b are now separated from each other in the area of arrow c. Furthermore, after the lower bag 37b has been removed from the lower container section 13, the lower container section is raised and passed over the ring 17 in a pressure-tight manner.
- a suitable lifting device not shown here
- the centrifuge drum protruding into the upper bag opening ensuring a pressure drop inside the bag during its rotation. Since the interior of the bag 37a, in which the centrifuge drum rotates, is also connected to the intermediate space 41 between the outer wall of the bag and the inner wall of the container 11 by means of a hose and pipeline 39, near the axis of rotation of the drum, the bag settles when the drum rotates to the walls surrounding it. The solids therefore get into the interior of the bag without any problems during spinning. Damage to the bag is safely avoided.
- the pressure in the container is increased and the lower container section is lowered, whereupon the bag walls are welded and severed, after which a new spinning cycle can be started.
- the solids are obtained sterile and with a very high yield.
- the hose and pipeline 39 can be provided with a shut-off valve 43 in order to close off the solids in the bag 37 against the ambient air.
- the hose and pipe run from the inner wall of the conical section 25b of the insert ring 25 through the housing 3, then through a ring 45 below the housing 3 and through the ring 17 engaging in the ring 45 to the intermediate space 41.
- Container 11 lower container section 13 upper container end 15 stepped ring 17th
