- Leukocyte depletion has been widely accepted as a method of improving the quality and tolerability of transfusions and has been mandatory in Germany since 2001.
- a significant branch is the depletion in in-line filtration systems, with a reduction of leukocytes is achieved by typically 3 orders of magnitude.
- the use of blood components as part of customized hemotherapy is based on their targeted use to compensate for deficits, such as the lack of volume through volume replacement solutions and the lack of oxygen carriers
- the total hemoglobin in the erythrocyte concentrate which determines the therapeutic dose, depends on the amount of whole blood collected, the physiological content of hemoglobin, and the preparation method.
- the commonly accepted whole blood quantities of 500ml, according to physiological reference values and resulting from the guidelines of the German Medical Association for approval for blood donation, between 62g and 68g total hemoglobin, which by the preparation to SAGM- or PAGGSM-suspended solutions by 10-20%, by the Removal of buffy coat by another 10%, and further reduced by the leukocyte depletion by a few percent.
- a 2006 study found a range of 42g to 68g total hemoglobin per bag of leukocyte-depleted packed red blood cells.
- DE 103 15 484 A1 discloses a system for the automatic filtration of blood products with a weight measuring cell is known, which is intended to measure the weight loss of a whole blood or weight gain of a filtrate. From the time course of the measurement data of the weight measuring cell is a monitoring of the duration of the filtering process, as well as, by comparing with reference curves, an assessment of the state of the filter device and the quality of the filtrate.
- DE 10 2005 040 518 B4 discloses a device for monitoring the filtration of stored blood with a sensor system in the region of the first and / or second supply line for detecting a blood flow through the supply line.
- An evaluation unit connected to the sensor system determines the duration of time required for the stored blood in a container to pass through the filter unit into a collection container.
- a process for producing a leukocyte and erythrocyte poor platelet preparation is described in DE 198 17 328 C2.
- the structure described here comprises an erythrocyte sensor located in front of a leukocyte filter for monitoring an erythrocyte nanoparticle which, if exceeded, destroys the filtration.
- the invention has for its object to provide an alternative device or an alternative method for producing a preferably leucocyte-depleted filtrate from a blood preparation.
- a filtration device with a separation device, a separation device downstream sensor for determining the hemoglobin concentration exiting the separation device fraction, a weighing system for measuring the weight of a fraction-containing collection container, and a computing unit for determining the total hemoglobin from the hemoglobin concentration and solved the weight.
- the separation device is or includes a leukocyte filter from which a leukocyte-depleted filtrate emerges as a fraction.
- This object is on the other hand by the inventive method with the steps of separating a blood sample by means of a separation device in at least two fractions, determining the hemoglobin concentration of the separating device from the fraction, feeding the fraction into a collecting container, measuring the weight of the collecting container together with fraction and Ermitteins of Total hemoglobin from the hemoglobin concentration and the weight solved by means of a computing unit.
- the separation of the blood preparation into at least two fractions is preferably a filtering of the blood preparation with a leukocyte filter so that the fraction leaving the separation device is a leukocyte-depleted filtrate.
- the device and method of the invention offer the advantage of providing a leukocyte-depleted filtrate in which the total hemoglobin of the filtrate is quantified so that a leukocyte-depleted filtrate with quantitated total hemoglobin can be prepared from a blood preparation.
- the invention includes the recognition that the determination of the total hemoglobin of the filtrate is desirable for economical use and targeted dosing of leukocyte-depleted filtrates, in particular packed red blood cells.
- the weighing system can continuously or periodically measure the weight of the collection container and its contents, and the sensor continuously or periodically determines the hemoglobin concentration of the filtrate. To be able to know and evaluate the hemoglobin concentration of the filtrate at any time, the measurement and determination can be carried out continuously. On the other hand, it may also be expedient for computational or economic reasons to periodically measure the weight of the collecting container together with its contents and / or to periodically determine the hemoglobin concentration of the filtrate.
- the arithmetic unit for determining the total hemoglobin on an integrator unit and / or an adding unit, each of which multiplies current values for the hemoglobin concentration with a respective weight gain and adds or integrates the product in terms of a sum sigma.
- the arithmetic unit has an integrator unit and / or the adder unit, which multiplies an average hemoglobin concentration by an increase in weight and adds or integrates the product in the sense of a sum sigma.
- the filtration device further comprises a shut-off means for terminating the filtration upon reaching a desired total hemoglobin.
- shut-off means may be a crimping clamp, a cutting clamp or another shut-off means suitable for terminating the filtration process, which is actuated either automatically by the user or automatically. In the case of manual actuation of the shut-off means, it is necessary to inform the user of the amount of total hemoglobin or of the minimum total amount of total hemoglobin.
- the filtration device therefore comprises a signaling means, for example a display or a sounding means, which is arranged for example on or in the arithmetic unit.
- the disconnection means is operatively connected to the signal means.
- the signaling means is designed to deliver electrical control pulses to the shutdown. The filtration process can be terminated automatically by the shutdown, which significantly increases the user comfort.
- the sensor for determining the hemoglobin concentration is an optical sensor. It has been shown that optical sensors, in particular Laser-optical sensors that can determine the hemoglobin concentration of blood preparations particularly accurately and reliably.
- the filtration device further comprises a supply line, a drain and the blood sample containing the blood supply containing supply tank, supply line, leukocyte filter, discharge and collecting container designed as a closed filtration system and are arranged in such a vertical direction to each other that that filtering blood preparation from the supply container via the supply line in the leukocyte filter, and the filtrate from the leukocyte filter via the discharge into the collecting container, at least due to a gravitational effect passes.
- Closed filtration systems meet the sterility requirements required in the processing of blood preparations and can, for example, be carried out very cost-effectively in PVC.
- the arrangement in said vertical direction allows a purely by gravity driven, and thus simple and inexpensive filtration process.
- the weighing system and the sensor can be fastened to a frame in such a way and the filtration system can be fastened to the frame in such a way that the discharge lies within the detection range of the sensor and the weighing system around supply container, feed line, white blood cell filter and discharge is substantially relieved.
- This has the advantage that filtration systems can be attached to the frame quickly and safely in a reproducible manner, or removed from the frame, and thus consistently good filtration results can be achieved.
