Embodiment Construction

[0064] first reference figure 1 , the blood recovery and autologous blood transfusion system according to the present invention comprises the following primary components:

[0065] ·Manually operable peristaltic pump unit 10

[0066] ·Suction rod 20

[0067] ·Blood collection bag 30

[0068] ·Blood processing bag 40

[0069] ·Blood transfer bag 50

[0070] · Anticoagulant container 60

[0071] The above components are connected by suitable conduits of generally conventional form and construction, usually flexible conduits of plastics material fitted with suitable connectors for connection to the respective components.

[0072] In use, the tip of the suction wand 20 is inserted into the blood at the wound site. As described in more detail below, operation of the peristaltic pump unit 10 pumps blood from the wound site to the blood collection bag 30 . The fluid drawn from the wound site is a turbulent blood / air mixture. Before the blood is retransmitted to the patient, a...

Abstract

Apparatus for blood processing comprising a blood collection reservoir (30), a blood collection conduit, a blood transfer conduit, and a manually operable pump unit (10) comprising first and second peristaltic pumps (10A, 10B). The first peristaltic pump is mounted about and acts upon the blood collection conduit. The second peristaltic pump is mounted about and acts upon the blood transfer conduit. The pump unit is provided with an actuator (112) adapted to switch the second peristaltic pump between an operative condition and an inoperative condition: in the operative condition the second peristaltic pump is engaged with the blood transfer conduit to convey blood from the blood collection reservoir while the first peristaltic pump is engaged with the blood collection conduit to convey blood from a wound site to the blood collection reservoir, and in the inoperative condition the second peristaltic pump is disengaged from the blood transfer conduit.

Description

technical field [0001] The present invention relates to an improved device for salvage (salvage, treatment) and autologous transfusion of blood drawn from a wound site. This device has particular utility in severe situations such as when power is unavailable. As such, the device may be useful in military applications including battlefield medical facilities. Background technique [0002] On the battlefield, uncontrolled hemorrhage is the leading cause of death, with two-thirds of these deaths being the result of incompressible (trunk) hemorrhage. In the recent Iraq-Afghanistan conflict, uncontrolled blood loss was the cause of death in 85% of potentially survivable battlefield situations and in 80% of those who died in military treatment facilities. Between 2001 and 2011, 25 percent of the 4,596 combat dead in these war zones likely survived, and 90 percent of the deaths occurred before the wounded reached medical facilities. Of the 4,090 mortally wounded soldiers, 1,391 ...
