Abstract

Systems, methods, and devices for providing subcutaneous hydration are disclosed. A system for providing subcutaneous hydration may include an infusion bag including a hydration fluid, a tubing removably connected to the infusion bag, a squeezable bulb at least partially encompassing the tubing for at least one of flushing and priming the tubing, and a deployment device including an integrated needle which is operative provide subcutaneous hydration through the needle. A deployment device for subcutaneous hydration includes a base may include a needle aperture, a spring-loaded barrel attached the base and including a needle, and a firing mechanism within the barrel for deploying the needle from the barrel and further operative to project the needle through the aperture only when a tent of skin has been raised within the aperture for injection. A method for providing subcutaneous hydration may include steps necessary to operate the systems and devices for subcutaneous hydration.

Claims

1. A deployment device (410, 510) for subcutaneous hydration, comprising:

a base (430, 530) including a needle aperture (433, 533);

a spring-loaded barrel (416, 516) attached to the base (430, 530) at an injection angle of 10 degrees to about 30 degrees, and including a needle (417, 517); and

a firing mechanism (450, 550) within the barrel (416, 516) for deploying the needle (417, 517) from the barrel (416, 516), the mechanism comprising at one actuator (454, 554) attached to the barrel (416, 516) and connected to a spring (455) so as to block a needle slot (452), the at least one actuator (454, 554) being depressed to unblock the needle slot (452) and permit deployment of the needle;

wherein the deployment device (410, 510) further includes at least one wing (440, 540) that attaches to the base (430, 530) for engaging the at least one actuator (454, 554), and

wherein the at least one wing (440, 540) engages the at least one actuator (454, 554) by gripping or pinching the at least one wing (440, 540) against the barrel (416, 516).

2. The deployment device of claim 1, wherein the needle (417, 517) is partially held within the barrel (416, 516) after injection.

3. The deployment device of claim 1, wherein the aperture (433, 533) accommodates needle (417, 517) movement while the needle (417, 517) is at least partially stabilized by the barrel (416, 516).

4. The deployment device (410, 510) of claim 1, wherein the base (430, 530) includes at least one of an antimicrobial material and a waterproof adhesive.

5. The deployment device (410, 510) of claim 1, wherein the barrel (416, 516) at least partially encompasses a tubing (408, 508) operative to provide hydration fluid to the needle (417, 517).

6. The deployment device (410, 510) of claim 1, further including a casing (560) attached to the base (430, 530) which at least partially encompasses the barrel (417, 517).

7. The deployment device (410, 510) of claim 6, wherein the casing (560) includes a slider track (562) for retracting the needle (417, 517) within the spring-loaded barrel (416, 516).

8. A system (100, 400) for providing subcutaneous hydration, comprising:

an infusion bag (102, 402) including a hydration fluid;

a tubing (108, 408) removably attached to the infusion bag (102, 402) and at least partially encompassed by a valve (106, 406); and

a deployment device (110, 410) attached to the tubing (108, 408);

wherein the deployment device (110, 410) comprises;

a base (430, 530) including a needle aperture (433, 533);

a spring-loaded barrel (416, 516) attached to the base (430, 530) at an injection angle of 10 degrees to about 30 degrees, and including a needle (417, 517);

a firing mechanism (450, 550) within the barrel (416, 516) for deploying the needle (417, 517) from the barrel (416, 516), the mechanism comprising at one actuator (454, 554) attached to the barrel (416, 516) and connected to a spring (455) so as to block a needle slot (452), the at least one actuator (454, 554) being depressed to unblock the needle slot (452) and permit deployment of the needle;

wherein the deployment device (110, 510) further includes at least one wing (440, 540) that attaches to the base (430, 530) for engaging the at least one actuator (454, 554), and

wherein the at least one wing (440, 540) engages the at least one actuator (454, 554) by gripping or pinching the at least one wing (440, 540) against the barrel (416, 516).

9. The system (100, 400) of claim 8, further comprising an adhesive base (132) for placement between a subcutaneous region (138) and the deployment device (110, 410).

10. The system (100, 400) of claim 9, wherein the adhesive base (132) includes an emulsion of at least one of prilocaine and lidocaine local anesthetic.

11. The system (100, 400) of claim 8, wherein the valve (106, 406) comprises a squeezable bulb (406) or a roller clamp (106).
