Autotransfusion system with portable detachable vacuum source

Claim 1

A system for collecting blood and other liquids from the wound of a patient and for reinfusing blood collected into the patient, said system comprising; a collecting means for collecting blood and being adapted to be connected in flow communication with the patient's wound, said collecting means including an outer rigid receptacle and an inner flexible bag, the rigid receptacle and the flexible bag forming an interstitial space therebetween, the flexible bag including a blood inlet port and a blood outlet port held in flow communication with an interior of the flexible bag, the inlet port being adapted for connection to drainage tubing leading to the wound, said outlet port being adapted for connection to a transfer tube; a manually operable portable vacuum source removably connected to said collecting means, the manually operable portable vacuum source being connectable to tubing in flow communication with the interstitial space of the collecting means, such that the manually operable vacuum source, when activated, causes a negative pressure within the interstitial space to cause said collecting bag to expand thereby drawing blood from the wound; a disposable fluid collection bag for connection to an exhaust port of the manually operable portable vacuum source to collect fluid from the manually operable portable vacuum source for disposal; the system being connectable in a first mode wherein the manually operable vacuum source is connectable by said collecting means and is in flow communication with the interstitial space to cause a negative pressure therein; said system being connectable in a second mode wherein said manually operable vacuum source disconnected from the collecting means, the interstitial space being in flow communication with ambient atmosphere and said outlet port adapted for connection to transfusion tubing, the manually operable vacuum source is adapted for direct connection to said drainage tubing and is activated to draw fluid from said wound into the manually operable vacuum source.

Claim 2

A system for collecting blood and other liquids from the wound of a patient and for reinfusing blood collected into the patient, said system comprising; a collecting means for collecting blood and being adapted to be connected in flow communication with the patient's wound, said collecting means including an outer rigid receptacle and an inner flexible bag, the rigid receptacle and the flexible bag forming an interstitial space therebetween, the flexible bag including a blood inlet port and a blood outlet port held in flow communication with an interior of the flexible bag, the inlet port being adapted for connection to drainage tubing leading to the wound, said outlet port being adapted for connection to a transfer tube; a manually operable portable vacuum source removably connected to said collecting means, the manually operable portable vacuum source being connectable to tubing in flow communication with the interstitial space of the collecting means, such that the manually operable vacuum source, when activated, causes a negative pressure within the interstitial space to cause said collecting bag to expand thereby drawing blood from the wound; a disposable fluid collection bag for connection to an exhaust port of the manually operable portable vacuum source to collect fluid from the manually operable portable vacuum source for disposal; the system being connectable in a first mode wherein the manually operable vacuum source is connectable by said collecting means and is in flow communication with the interstitial space to cause a negative pressure therein; said system being connectable in a second mode wherein said manually operable vacuum source disconnected from the collecting means, the interstitial space being in flow communication with ambient atmosphere and said outlet port adapted for connection to transfusion tubing, the manually operable vacuum source is adapted for direct connection to said drainage tubing and is activated to draw fluid from said wound into the manually operable vacuum source.

Claim 3

A system for collecting blood and other liquids from the wound of a patient and for reinfusing blood collected into the patient, said system comprising; a collecting means for collecting blood and being adapted to be connected in flow communication with the patient's wound, said collecting means including an outer rigid receptacle and an inner flexible bag, the rigid receptacle and the flexible bag forming an interstitial space therebetween, the flexible bag including a blood inlet port and a blood outlet port held in flow communication with an interior of the flexible bag, the inlet port being adapted for connection to drainage tubing leading to the wound, said outlet port being adapted for connection to a transfusion tube; a manually operable portable vacuum source removably connected to said collecting means, the manually operable portable vacuum source being connectable to tubing in flow communication with the interstitial space of the collecting means, such that the manually operable vacuum source, when activated, causes a negative pressure within the interstitial space to cause said collecting bag to expand thereby drawing blood from the wound; a cap connected by a strap to the drainage tube and a cap connected by a strap to the inlet port, each strap including fingers which interlock with one another, the fingers interlocking constitute means for coding the straps for proper connection of their respective tubes; the system being connectable in a first mode wherein the manually operable vacuum source is connectable by said collecting means and is in flow communication with the interstitial space to cause a negative pressure therein; said system being connectable in a second mode wherein said manually operable vacuum source disconnected from the collecting means, the interstitial space being in flow communication with ambient atmosphere and said outlet port adapted for connection to transfusion tubing, the manually operable vacuum source is adapted for direct connection to said drainage tubing and is activated to draw fluid from said wound into the manually operable vacuum source.

Claim 4

A system for collecting blood and other liquids from the wound of a patient and for reinfusing blood collected into the patient, said system comprising; a collecting means for collecting blood and being adapted to be connected in flow communication with the patient's wound, said collecting means including an outer rigid receptacle and an inner flexible bag, the rigid receptacle and the flexible bag forming an interstitial space therebetween, the flexible bag including a blood inlet port and a blood outlet port held in flow communication with an interior of the flexible bag, the inlet port being adapted for connection to drainage tubing leading to the wound, said outlet port being adapted for connection to a transfusion tube; a manually operable portable vacuum source removably connected to said collecting means, the manually operable portable vacuum source being connectable to tubing in flow communication with the interstitial space of the collecting means, such that the manually operable vacuum source, when activated, causes a negative pressure within the interstitial space to cause said collecting bag to expand thereby drawing blood from the wound; a cap connected by a strap to the drainage tube and a cap connected by a strap to the inlet port, each strap including fingers which interlock with one another, the fingers interlocking constitute means for coding the straps for proper connection of their respective tubes; the system being connectable in a first mode wherein the manually operable vacuum source is connectable by said collecting means and is in flow communication with the interstitial space to cause a negative pressure therein; said system being connectable in a second mode wherein said manually operable vacuum source disconnected from the collecting means, the interstitial space being in flow communication with ambient atmosphere and said outlet port adapted for connection to transfusion tubing, the manually operable vacuum source is adapted for direct connection to said drainage tubing and is activated to draw fluid from said wound into the manually operable vacuum source.
