Dry Wash

The unique solution in Orthopaedic Post-Operative blood autotransfusion

When transferring the blood collected from the reservoir to the reinfusion bag, most “no wash devices” allow everything to be transferred (blood shed, FPH, lipids, etc.); others devices are equipped with supernatant separators which ensure that a fixed volume (i.e. 50ml) remains in the reservoir, keeping:

  • The entire lipid layer (in the reservoir);
  • A portion of the supernatant layer (in the reservoir).

The fixed volume might not fully remove the entire supernatant layer, due to patients’ variable exudated volume. Thanks to an electronic sensor, located between the reservoir and reinfusion bag, neither the supernatant nor the lipid layer are transferred to the reinfusion bag.

The blood is reinfused through the 40 μm GOCCIA filter (microaggregate removal > 40 μm: 95%3) in order to minimize risk to the patient (such as pulmonary microembolism caused by circulating microaggregates).

DRY WASH is an innovative system, associated with Ortho P.A.S.
DRY WASH, that can automatically remove the entire supernatant3
layer, eliminating the majority of harmful substances, thus reducing
the likelihood of transfusion reaction.

  • The recovered and subsequently reinfused
    blood remains completely sterile (no contact
    with non-sterile external air).
  • Complete operator protection maintaining of blood sterility if the device overturns or falls.
  • Protection from the recovered blood contaminating the environment.
  • Reinfusion can also be done during the recovery phase.
  • The closed circuit prevents bacterial contamination.
  • Multiple closed circuit reinfusions can be done at the same time.
  • Variable supernatant and lipid layers are automatically held in the reservoir.
  • Protection of multi-use components (suction pump) thanks to the hydrophobic sterilizing filter.
  • Prevents the spread of infective and immunological complications (closed circuit system).
  • The blood is made immediately available for reinfusion.
  • Eliminates the majority of harmful substances.
