The strap can be worn by a patient to support the weight of the automated body fluid drain control apparatus. The apparatus for controlling the collection of body fluids includes a drainage tube and a fluid collection chamber in fluid communication with the drainage tube. The fluid collection chamber includes a first valve, and the fluid collection chamber is configured such that when a predetermined amount of fluid is collected in the collection chamber before a first predetermined period of time elapses, the collection chamber ceases collecting fluid. ## Claims ### Claim 1 A portable body fluid collection device comprising: an apparatus for controlling the collection of body fluids that includes a drainage tube, and a fluid collection chamber in fluid communication with the drainage tube, wherein the fluid collection chamber includes a first valve, and wherein the fluid collection chamber is configured such that when a predetermined amount of fluid is collected in the collection chamber before a first predetermined period of time elapses, the collection chamber ceases collecting fluid, and at least one strap associated with the apparatus for controlling the collection of body fluids, wherein the strap can be worn by a patient to support the weight of the automated body fluid drain control apparatus. ### Claim 2 (depends on 1) The portable body fluid collection device of claim 1 wherein the apparatus for controlling the collection of body fluids further includes a measuring device that measures the amount of fluid entering the collection chamber through the first valve during the predetermined first period of time, wherein the first valve has an open and a closed state, wherein the first valve is normally open and allows body fluids to flow into the collection chamber, wherein if during the first period of time a predetermined volume of body fluid enters the chamber, the first valve is closed. ### Claim 3 (depends on 2) The portable body fluid collection device of claim 2 wherein the apparatus for controlling the collection of body fluids further includes a second valve having an open and a closed state, wherein the second valve is normally closed so that body fluids collect in the chamber, and wherein the second valve can be opened to empty the collection chamber. ### Claim 4 (depends on 3) The portable body fluid collection device of claim 3 wherein after the first period of time has elapsed, the first valve is opened and the second valve is closed and a second period of time starts, wherein the first period of time is equal to the second period of time. ### Claim 5 (depends on 1) The portable body fluid collection device of claim 1 further comprising a container, wherein the apparatus for controlling the collection of body fluids is disposed in the container, and the strap is connected to the container. ### Claim 6 (depends on 5) The portable body fluid collection device of claim 5 wherein the drainage tube is configured to be inserted into a patient's subarachnoid region at an insertion point, and wherein the container and strap are configured such that when the container is worn by a patient, the first valve is positioned below the insertion point. ### Claim 7 (depends on 6) The portable body fluid collection device of claim 6 wherein the container is vertically adjustable between at least a first and a second position. ### Claim 8 (depends on 7) The portable body fluid collection device of claim 7 wherein the container is a backpack. ### Claim 9 A method of collecting body fluid, the method comprising the steps of: providing an apparatus for controlling the collection of body fluids that includes a drainage tube, and a fluid collection chamber in fluid communication with the drainage tube, wherein the fluid collection chamber includes a first valve, and wherein the fluid collection chamber is configured such that when a predetermined amount of fluid is collected in the collection chamber before a first predetermined period of time elapses, the collection chamber ceases collecting fluid, inserting an end of the drainage tube into a patient's subarachnoid region at an insertion point, securing the apparatus for controlling the collection of body fluids to the patient's body at a first position, wherein in the first position, the first valve is located vertically below the insertion point. ### Claim 10 (depends on 9) The method of claim 9 wherein the apparatus for controlling the collection of body fluids is secured to the patient's body via a strap. ### Claim 11 (depends on 10) The method of claim 10 wherein the strap is connected to a container, and wherein at least a portion of the apparatus for controlling the collection of body fluids is disposed in the container. ### Claim 12 (depends on 11) The method of claim 11 wherein the container is a backpack.
