Abstract

An apparatus for treating a hemorrhaging wound and returning blood to the body includes at least one vacuum hose; tubing to return blood to the body; a reservoir to temporarily contain the blood, an ejectable filter between the vacuum hose and the reservoir, a temperature regulator to regulate the temperature in the reservoir; at least one pressure regulator connected to the at least one vacuum hose; a vacuum pump connected to the at least one pressure regulator, and an infusion pump connected to the tubing to return blood to the body. Blood is returned to the body via multi access catheter and/or consistent with present and future rapid infusion procedural methods that could change according to severity of injuries and the need for alternate vascular access points and/or infusion delivery protocols.

Claims (34)

1 . An apparatus to treat a hemorrhaging wound, comprising:

at least one vacuum hose;

at least one IV tubing, catheter, or multi access catheter to return blood to a body;

a reservoir to temporarily contain the blood issuing from the vacuum hose;

an ejectable filter between the vacuum hose and the reservoir;

a temperature regulator to regulate a temperature in the reservoir;

at least one vacuum pump connected to at least one pressure regulator;

3 infusion pumps connected to the IV tubing, the catheter, or the multi access catheter to return blood to the body, each infusion pump having a replaceable heated filter downstream and a separate tubing to return blood to the body.

2 . The apparatus of claim 1 , wherein there are two vacuum hoses.

3 . The apparatus of claim 2 , further comprising a vacuum pump switch connected to each vacuum hose.

4 . The apparatus of claim 1 , further comprising an infusion pump switch connected to each infusion pump.

5 . The apparatus of claim 1 , wherein there are 3 of the IV tubing, the catheter, or the multi access catheter to return blood to the body, with each of the IV tubing, the catheter, or the multi access catheter being attached to a separate infusion pump of the 3 infusion pumps.

6 . The apparatus of claim 1 , wherein the reservoir is a transparent plastic reservoir.

7 . The apparatus of claim 1 , wherein there is a replaceable filter downstream from each vacuum pump.

8 . The apparatus of claim 1 , wherein there is a replaceable filter downstream from each infusion pump.

9 . The apparatus of claim 1 , wherein each replaceable filter is an about 200 micron filter.

10 . The apparatus of claim 1 , wherein the temperature regulator includes a temperature sensor, a heater and a controller.

11 . The apparatus of claim 1 , wherein a blood pressure cuff is in electronic contact with the apparatus.

12 . The apparatus of claim 11 , further including a blood pressure display in communication with the blood pressure cuff.

13 . The apparatus of claim 1 , further comprising a hydrophobic vacuum attachment for treating a chest wound, the hydrophobic vacuum attachment comprising a pillow part attached to a drain part having a vacuum connection point and an air vent.

14 . The apparatus of claim 1 , further comprising an adhesive vacuum attachment, the adhesive vacuum attachment comprising a suction head, an adhesive layer on the suction head, a vacuum connection port on the suction head, and an air vent in communication with the vacuum connection port.

15 . A procedure for treating a hemorrhaging wound, comprising:

providing an apparatus of claim 1 ,

administering a dose of anticoagulant to the apparatus before or during the procedure;

applying a vacuum to vacuum blood from the hemorrhaging wound;

turning on at least one of the infusion pumps;

filling the IV tubing to a tip of an insertion attachment;

expelling blood to clear the IV tubing of any trapped air; and

inserting the IV tubing via a rapid infusion catheter into a vein consistent with blood infusion protocols; and

adjusting millimeters of mercury/flow rate using pump pressure sensitivity sliding dials according to how profuse the hemorrhaging wound is hemorrhaging and apparatus efficiency.

16 . The procedure of claim 15 , further comprising adding additional infusion points.

17 . The procedure of claim 15 , further comprising adjusting the flow rate in accordance with how much the wound is bleeding.

18 . The procedure of claim 17 , wherein the flow rate is from about 2 ml/min to about 2500 ml/min.

19 . The procedure of claim 15 , wherein there are 2 vacuum pumps and 3 infusion pumps.
