A wearable EVD system having a ventricular catheter and transducer supported proximately to a patient's ear by a mount, such as supporting headband or ear clip. An adjustable orifice valve or a spring-loaded needle valve is used to control the amount of CSF that drains into a drip chamber suspended on the patient for periodic measurement and emptying into a similarly located drainage bag, thereby avoiding the need for an IV pole and allowing the patient more mobility without disrupting drainage of CSF.

1. A wearable external ventricular drain system, comprising a ventricular catheter;a head mount adapted to releasably engage a head of a patient;a valve engaged with the head mount to locate the valve in proximity of a ventricle of the patient, the valve having an input interconnected to the ventricular catheter and an output, a fluid passageway connecting the input and the output, a needle seat positioned in the passageway, an adjustable needle having a needle head positioned in the fluid passageway for movement into and out of engagement with the needle seat, a post interconnected at one end to the needle head and to a knob at the opposing end, wherein the post is interconnected to the needle head via a spring and wherein the needle head with the spring is operable to move relative the needle seat to allow a flow of fluid from the input to the output;a drain line interconnected to the output of the valve;a securement strap adapted to engage one of a chest and a shoulder of the patient;a drip chamber fluidly connected to the drain line and engaged with the securement strap, the drip chamber operable to provide a visual measure of a collection of the flow of fluid; anda reservoir interconnected to the drainage tubing downstream of the drip chamber. 2. The system of claim 1, further comprising at least one sensor interconnected to the catheter and the mount. 3. The system of claim 2, wherein the sensor is selected from the group consisting of a pressure transducer, a flow sensor, and a glucose sensor, and combinations thereof. 4. The system of claim 2, wherein the sensor is adapted to wirelessly transmit data to a remotely positioned host. 5. The system of claim 2, wherein the sensor is electrically interconnected to a remotely positioned host and transmits data to the host. 6. The system of claim 1, further comprising a stopcock interconnected to the drip chamber for emptying of the drip chamber. 7. The system of claim 6, further comprising drainage tubing interconnected to the stopcock and in fluid communication with the drip chamber when the stopcock is in an open position. 8. The system of claim 1, further comprising a reservoir interconnected to the drain line, the reservoir engaged with the securement strap. 9. A valve for an external ventricular drain system, comprising: a fluid passageway having an input and an output, the input fluidly connected to a ventricular catheter;a needle seat positioned in the passageway around the input;an adjustable needle having a needle head positioned in the fluid passageway over the input for movement into and out of engagement with the needle seat;a post interconnected at one end to the needle head and to a knob at the opposing end, wherein the post is interconnected to the needle head via a spring;a head mount to locate the valve in proximity of a ventricle of a patient; anda drip chamber fluidly connect to the fluid passageway, the drip chamber coupled to a securement strap adapted to engage one of a chest and a shoulder of the patient, the drip chamber operable to provide a visual measure of a collection of the flow of fluid, and wherein the needle head with the spring is operable to move relative the needle seat to allow a flow of fluid from the input to the output.
