Definitions
- the claimed invention relates to a centrifuge for processing blood and blood components and of which the function is based on an effective utilisation of blood processing bags of ring type with associated, if required, secondary bags and other accessories.
- the secondary bags and the other accessories are of standard type within the area of technology and together these and the characteristic ring bags that are necessary for the centrifuge, in accordance with the invention, could be joined to the bag intended for various special blood processing purposes.
- This bag set which is completely manufactured of inert plastic material allowing the blood and blood components to be seen, can therefore have different structures and designs depending on which type of blood processing they are intended for, but they are all based on the utilisation of the ring bag as a basic component.
- the intention of the claimed invention is to offer a blood processing centrifuge with its special shape that makes it possible to limit the number of manual handling stages to a minimum, within every type of blood processing operation in which a centrifuging stage is included.
- centrifuges intended for processing blood and blood components and also several types of ring bags intended for using in these centrifuges are to be found described in, for example, WO 87/06857, US-A-5, 114,396, US-A-5,723,050, WO 97/30715, WO 98/35757.
- centrifuges described therein it is primarily those that are included in the two latter-named patent documents that purpose-intended ring bags are utilised combined with standard secondary bags.
- the centrifuge in accordance with the invention, has been equipped with a small number of, for example, three to five supports with a little larger diameter, divided at the same height as the intended position for the ring bag's inner periphery onto which the purpose-made guide holes along the ring bag's inner periphery are located.
- the clamping function limits, through its greater contact area, the load on the ring bag's inner edge and prevents it from slipping over or, in some other way, being released from the supports while the centrifuging is activated.
- the inner lid one or several photocells are advantageously arranged which after centrifuging are used for determining when emptying the ring bag shall be interrupted, in other words, when approaching the interface between the desired and the non-desired component.
- the supports can thus be equipped with built-in clamping instruments in which the different tubes between the ring bag and secondary bags can be arranged and with which the passage through these tubes can be opened and closed.
- clamp valves can, on condition that there is sufficient electric power via the centrifuge rotor, be combined with a cutting and welding function with which the tube which passes the clamp valve in question can be sealed and cut as soon as the connecting function, which it represents, is no longer needed.
- Another occasion when it simplifies how the ring bag is to be placed in the centrifuge is when the used bag set contains a cell trap for which there should suitably exist a preferred space in the centrifuge rotor or on its inner lid.
- a similar cell trap can, for example, be of the type that is described in WO 97/30715, which in principle consists of one on one priorly defined arc in the slightly longer connecting tube in the centrifuge's rotating part.
- a further improvement to the blood processing centrifuge in accordance with the invention, relates to the production of medicinally valuable blood platelet plasma from the concentrate product, which is designated Buffy Coat at blood donor centres.
- the original material which is viscous, is diluted with a standard diluting solution.
- T-Sol An example of a similar standard diluting solution that is used profusely in this area is generally designated T-Sol.
- T-Sol An example of a similar standard diluting solution that is used profusely in this area.
- the Buffy Coat is available in the form of concentrates from previous extractions of red blood cells and plasma from whole blood. Each concentrate batch of Buffy Coat is, as a rule, too small, even after diluting with the relevant diluting solution, to be worth an individual centrifuging.
- the number of bags with the original material that is intended to be included in a centrifuging are connected via separate connecting tubes in each bag set. These connecting tubes are then in turn joined in a multi- way connector to which the diluting solution bag's connecting tube is also connected.
- the latter connecting tube is applied at the same time to a clamp valve on one of the centrifuge rotor's supports while the bags with Buffy Coat are attached to the aforementioned cassette and the bag with the diluting solution is suspended in the intended holder sufficiently high up for the desired amount of diluting solution to be able to be added to each respective Buffy Coat bag.
- the addition of the diluting solution to the Buffy Coat bags is then controlled by the aforementioned clamp valve, which, in turn, is controlled by a control program that is part of the centrifuge's control system, which also selects the time for starting the motor and the length of time it must be operated. It is most suitable to add the diluting solution in several portions with a motor operation between each addition. Resolving the Buffy Coat in the diluting solution is carried out without any manual shaking operation. As the motor operates the cassette with a special forwards and backwards movement we avoid the problem associated with damaging the various tubes. It is only the tube between the ring bag and the final product's storage bag that is not affected by the mixing operation.
- the contents of all the bags are added to the ring bag included in the bag set via a separate connecting tube, which is also connected to the previously named multi- way connector and which, on its way to the ring bag, is placed in the clamp valve on another support by which this connection is controlled.
- a separate connecting tube which is also connected to the previously named multi- way connector and which, on its way to the ring bag, is placed in the clamp valve on another support by which this connection is controlled.
- FIG. 1 a section through a typical centrifuge, in accordance with the invention
- Fig. 2 the ring bag intended for the centrifuge with the position of the section marked with line I-I, in accordance with Fig. 1 Fig. 3 bag set intended for blood platelet production from Buffy Coat Fig. 4 centrifuge equipped with autopooling
- the centrifuge shown in Fig. 1 has rotor 1, centre chamber 2 where, for example, the final storage bags for the produced products can be located during the centrifuging operation while those connected to the same are filled with the desired component from the centrifuge's ring bag. Furthermore, ring chamber 3 is included for ring bag 4. In the latter the actual centrifuging operation is carried out. Beneath the ring bag and separated from it by a membrane is chamber 5 which can be filled with a hydraulic fluid with the purpose of exposing ring bag 4 to an external pressure for emptying the said ring bag. Centrifuge rotor 1 has furthermore a clockwise rotating lid 6 with the ring bag in which securing function 7 for ring bag 4 is built in. In Fig.
- ring bag 4 is drawn filled with fluid 8, which shall be centrifuged.
- centrifuge rotor 1 there are three built-in supports 9-11. Of these only support 9 is shown on Fig. 1 but how the others internal position relates to this is shown in Fig. 2.
- supports which have a primary function of defining ring bag 4's position in the centrifuge and holding the bags in position during centrifuging guide groove 12 for different connecting tubes for the blood processing set can moreover be arranged.
- the clamping function can be built in on the one hand, which makes them usable as a check valve for regulating the connection between the various parts of the bag sets and, on the other hand, as a welding function with which sealing and cutting of the same tubes can be carried out.
- Support 9 thus presupposes movement in arrow 13's direction and by could therefore function as a clamp valve for the arranged tube in guide groove 12.
- the welding function on the supports requires access to electric power in the centrifuge rotor and, apart from that, requires contact lines between the rotor and centrifuge stand for the different control systems of the centrifuge.
- Ring bag 4 as shown in fig. 2 consists of two sheets of some suitable plastic material joined together along the welded edges 17 and 18. Between the welded edges 17 and 18 the internally open ring chamber is formed, which is utilised during centrifuging. Besides ring welds 17 and 18 some welded points for strengthening around the holes which are intended for locating on supports 9-11. All the ring bags shown on the figures are formed with a central opening, which primarily corresponds to the centre chamber 2 opening. This is to simplify the passage to the centre chamber. On Fig. 2 this opening is designated 19. The ring bag shown in Fig.
- FIG. 2 has an opening for supports 9-11 as well as input and output tubes 20 and 21 attached to the ring bag's top and bottom sides by means of the welded sleeve couplings 24, i.e. securing parts in the form of a short piece of tube with a diagonally arranged flat securing collar which, in turn, is welded to the ring bag's top and bottom sides in which the connecting tubes in turn are secured by welding.
- the input and output tubes can also be secured to each respective welded edge, i.e. weldings 17 and 18 on Fig. 2.
- Fig. 2 On Fig.
- the bag set for producing blood platelets from the Buffy Coat consists of ring bag 22, a bag with diluting solution 23, four connecting tubes 25-28 (the number of connecting tubes can vary but, as a rule, should be between 4 and 6), with each one intended for welding to a bag with Buffy Coat, multi-way connector 29 which, on the one hand, via a tube 30 is connected to the diluting solution bag 23 and, on the other hand, to tube 31 and to ring bag 22. From the latter tube 32 is connected to final storage bag 33.
- tube 30's connection to the diluting solution bag 23 there is blocking switch 45, which when required for starting the addition of diluting solution to the bags with Buffy Coat connected to tubes 25-28 can be opened by bending the tube. Before the blocking switch is opened connecting tube 30 shall be arranged in the guide groove 12 in one of the supports 9-11 that has the clamp valve function that is intended for controlling the addition.
- the figure shows a position with four blood bags containing Buffy Coat 37-40 suspended in cassette 41, which is mounted on the inside of the centrifuge's outer lid.
- Blood bags 37- 40 individual outputs have been connected, by sterile welding, to tube connectors 25-28 and the fluid content of the bags has, via the tubes and connecting tube 31 been transferred over into ring bag 22.
- bags 37 ⁇ 10 have been supplied with washing fluid and diluting solution from diluting solution bag 23 suspended in holder 44.
- Diluting solution bag 23 is suspended sufficiently high above bags 37-40 to allow the diluting solution in sufficient amounts to be added to these bags as soon as blocking switch 45 in tube 30 and clamp valve in support 11, which tube 30 passes, are opened.
- the flushing out of the blood bags can, if required, be carried out in two or several consecutive flushing operations.
- cassette 41 and holder 44 are removed from the centrifuge lid whereby the centrifuge is closed and centrifuging is carried out.
- Final storage bag 33 is located in the centrifuge's centre chamber 45.
- Emptying the ring bag is interrupted by photocell 52 when it is registered that the interface between the desired lighter substance and the darker non-desired concentrate product is starting to approach the outlet through tube 32. After that tube 32 is sealed by sterile welding and sealed in one of the supports 9-11 after which the ring bag with non-desired concentrates of red blood cells, etc., can be rejected.
- an adapted database directly connected to a barcode reader is utilised to make all the processed blood products in the centrifuge, in accordance with the invention, directly traceable at the same time that the database also contains all the required control criteria for feasible blood product processing stages in the centrifuge.
