EATSET: EMERGENCY AUTO TRANSFUSION SET |
Workshop Demo
Blood Salvage
Seminar Lecturers |
Autotransfusion is an established technique for the collection and subsequent reinfusion
of the patient's own blood. It not only prevents transmission of diseases but also avoids
immunological complications of homologous transfusion. Autotransfusion permits greater
flexibility in the use of blood bank supply.
ADVANTAGES OF AUTOTRANSFUSION
Rapid availability of blood. Does not require any blood storage facilities.
No risk of disease transmission.
No incompatibility of product transfused.
No risk of alloimmunization.
Conserves Blood Banks supply.
SYSTEM DESCRIPTION
EATSET is a system for recovering blood from internal bleeding. Its primary application is
for patients with internal haemorrhage. Such blood can be safely reinfused if processed
within the first 24 hours after haemorrhage. Blood is aspirated into a collection
container and is reinfused by gravity to the patient after a filtration process.
|
FEATURES
The main features of the EATSET are as follows:
Rapid recovery of blood from internal heamorrhage.
Simple to use: can be totally manually operated.
Closed system: no risk of infection transmission. |
 |
|
Cost effective. Main
container can be re-used after sterilisation.
Only filters and tubing lines are discarded after use.
Can be manually operated
Low vacuum
Minimal trauma to red blood cells |

Medical practice being an essential component of our health delivery program, has profound
influence over the effectiveness of our health policies and the attainment of economic and
social development. |

High prices of medical equipment/reagent/drugs needed for effective medical practice is
the major constraint to the development of medical practice in Nigeria.
Thus, with our limited foreign exchange earnings, the sourcing of local materials towards
medical manufacturing becomes a cardinal objective of the import dependent Nigerian
Manufacturing industry. Unlike other industries, the medical industry is a specialized one
requiring a wide range of complex materials used as active ingredients and excipients.
Nigeria is blessed with a high level of natural and human resources.
A quick review of medical equipment revealed that essentially, they are mostly plastic,
rubber steel, glass, cotton and iron which are abundant in Nigeria. The Raw Material
Research and Development Council in pursuance of relying less on imported materials
embarked on the national R & D involving also design and fabrication of machinery.
Also R & D work has been carried out in the area of drugs and pharmaceutical
ingredients. Details will be discussed at the seminar.

Ectopic pregnancy remains a major cause of massive obstetric haemorrhage in early
pregnancy with an increased risk of maternal mortality. |
|
In
1993, there were 113 surgically treated ectopic pregnancies giving an institutional figure
of 0.03 per maternity out of which there were 3 maternal deaths. The vast majority of the
patients presented late with acute collapse due to massive intra-peritoneal haemorrhage
from ruptured ectopic pregnancy.
As soon as the diagnosis was made resuscitative measures were commenced and surgical
treatment carried out but delay due to lack of compatible banked blood amongst other
factors do occur.
The average blood loss was 2750mls.. Auto transfusion aws not carried out and tarnsfusion
of an average of 3 pints of compatible blood was usual. |

Auto-transfusion is an established technique for salvaging patient’s blood. It is
widely used in the western world for elective surgery in period postoperative
interventions. The technology is generally based on sophisticated equipment using
centrifugation, allowing haemoconcentration and cell washing. Nevertheless a much simpler
and more affordable device is missing for emergency situations, especially in developed
countries. |
 |
|
This paper presents a new simple device offering an answer to this problem. Aimed
at emergency autotransfusion , it allows to recover blood from patients having internal
hemorrhage. The system is entirely closed and composed of a reusable collection device
holding a disposal filter, with suction and retransfusion lines connected. Blood suction
from body cavities is performed through a hand held vacuum pump. Its ability to function
without electrical power makes it a system of choice in regions where energy distribution
is lacking or unreliable.
The primary application of this device will be for cases with internal bleeding as found
in accident victims, women with ectopic pregnancies, aneurysmal ruptures, trauma leading
to the collection of blood in body activities. Easy to operate, its modular configuration
establishes the platform for a new generation of simple blood salvage devices.
