Abstract
A portable body fluid collection device that includes an apparatus for controlling the collection of body fluids and at least one strap associated with the apparatus for controlling the collection of body fluids. 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.
Claims16
An apparatus for controlling the collection of body fluids, the apparatus comprising:
- a collection chamber,
- a tube in fluid communication with the collection chamber,
- a measuring device that measures the amount of fluid flowing through the tube during a predetermined first period of time,
- a valve having an open and a closed state, wherein the valve is normally open and allows body fluids to flow therethrough and to the collection chamber, wherein if during the first period of time a predetermined volume of body fluid passes the measuring device, the valve is closed and the collection chamber ceases collecting fluid, wherein after the first period of time, the valve is opened and a second period of time starts, and wherein the first period of time is equal to the second period of time.
An apparatus for controlling the collection of body fluids, the apparatus comprising:
- a collection chamber, a tube in communication with the collection chamber, a valve, the valve having an open and a closed state, wherein the valve is normally open and allows body fluids to flow into the collection chamber, a flowmeter that measures the amount of fluid flowing through the tube and entering the collection chamber through the valve as a function of time, and a controller that automatically controls the valve, wherein the controller closes the valve when a first amount of fluid enters the collection chamber, wherein the controller reopens the valve after a first period of time has elapsed and a second period of time starts, wherein during the second period of time the controller closes the valve when the first amount of fluid enters the collection chamber, and wherein the controller reopens the valve after the second period of time has elapsed.
A method for draining body fluid from the body so that no more than a preselected amount of body fluid is drained from the body during a preselected period of time, the method comprising the steps of:
- collecting body fluids in a chamber, a tube in communication with the chamber, a valve having an open and a closed state, wherein when the body fluid is being drained, the valve is open so that the body fluids collect in the chamber;
- measuring with a measuring device the fluid collected in the chamber over the preselected period of time to determine whether the amount collected is at or less than the preselected amount,
- if the preselected amount of fluid is collected in the collection chamber before the period of time has elapsed, the valve closes,
- once the preselected time period has elapsed, the process is repeated and the preselected time period recommences.
