Wearable intravenous fluid delivery system
An intravenous (IV) fluid delivery system include an IV bag and a fluid delivery device. The IV bag is made of many fluidic channels that keep the fluid distributed across the bag such that the bag may be easily and comfortably wrapped around the arm and shoulder of a person. At least some of the fluidic channels have a slanted shape to maximize emptying the contents of the IV bag as the fluid is injected to the patient's vein. The system includes a pump that moves the fluid into a tube and a needle that is connected to a person's vein. The processor repeatedly turns the pump on or off to gradually transfer the fluid from the IV bag into the person's vein. The processor controls the delivery of the fluid based on the patient's biometric data and/or hand movements as measured by the fluid delivery device.

8. The wearable intravenous bag of claim 1 , wherein the fluidic channels of at least a subset of the first plurality of fluidic channels are substantially parallel to each other.
9. The wearable intravenous bag of claim 1 , wherein at least a subset of the first plurality of fluidic channels remains substantially parallel to each other after the intravenous bag is bent around the adjacent fluidic channels of the first plurality of fluidic channels.
10. The wearable intravenous bag of claim 1 , wherein the fluidic channels of at least a subset of the second plurality of fluidic channels are substantially parallel to each other.
11. The wearable intravenous bag of claim 1 , wherein at least a subset of the second plurality of fluidic channels remains substantially parallel to each other after the intravenous bag is bent around the adjacent fluidic channels of the second plurality of fluidic channels.
12. The wearable intravenous bag of claim 1 further comprising:
a set of one or more tubes that carries the fluid from the first plurality of fluidic channels to the second plurality of fluidic channels; and
a set of one or more connectors connecting the shoulder section and the arm section;
wherein each tube in the set of tubes passes through a connector in the set of one or more connectors.
13. The wearable intravenous bag of claim 12 , wherein the shoulder section, the arm section, and the set of one or more connectors form a unitary body.
14. The wearable intravenous bag of claim 1 further comprising a pair of slits on the arm section, the pair of slits configured to hold a strap to hold the arm section against the arm of the person.
15. The wearable intravenous bag of claim 1 further comprising one or more pairs of slits, each pair of slits comprising a slit located on the shoulder section and a slit located on the arm section, each pair of slits configured to hold a strap to connect the shoulder section to the arm section.
16. The wearable intravenous bag of claim 1 further comprising a fluid transfer pipe that carries the fluid from the second plurality of fluidic channels to a fluid delivery device.
17. The wearable intravenous bag of claim 1 further comprising an injection port configured to receive a quantity of fluid other than the fluid inside the intravenous bag through one of a Y-set connector, a T-set connector, and a V-set connector.
18. The wearable intravenous bag of claim 1 , wherein the wearable intravenous bag further comprises a connection configured to fluidically connect the wearable intravenous bag to another intravenous bag that is worn by the person.
19. The wearable intravenous bag of claim 1 , wherein the fluid is one or more of a medication, a saline solution, a blood product, and nutrition.
20. The wearable intravenous bag of claim 1 further comprising a tag configured to store parameters comprising an identification of a patient, an identification of contents of the fluid in the wearable intravenous bag, and a fluid delivery schedule.
