Abstract

The invention provides a subcutaneous infusion device including a delivery tube having a central lumen and a closed first end and an open second end. The device further includes a support base attached adjacent a first end of the delivery tube; and a plurality of needles extending substantially perpendicular to the support base and in communication with the central lumen of the delivery tube. A method for hydrating a patient in accordance with the invention includes pressing a support base against a skin surface of the patient and inserting a plurality of needles into a subcutaneous skin layer responsive to the pressing. The method further includes delivering a saline fluid to the subcutaneous skin layer through the needles via a delivery tube.

Claims (20)

1. A subcutaneous infusion device, comprising:
a flexible delivery tube including a central lumen, a closed first end and an open second end, the flexible delivery tube including a plurality of needle openings;
a flexible planar support base attached adjacent a first end of the delivery tube, the support base having a first side for supporting the flexible delivery tube and a second side; and a plurality of needles each needle having a first portion having a communication end, the first portion disposed within the central lumen of the flexible delivery tube and a second portion having an open end for penetrating skin and delivering fluid from the central lumen to a subcutaneous tissue, the second portion perpendicular to the first portion and extending through one of the plurality of needle openings and extending substantially perpendicular to the support base and in communication with the central lumen of the delivery tube;
wherein the support base includes a plurality of openings, each of the plurality of openings for receiving one of the plurality of needles.
2. The device of claim 1 further comprising a luer fitting attached to the second end of the delivery tube.
3. The device of claim 1 wherein the needles are sized to allow a flow rate of approximately 120 to 200 cc/hr.
4. The device of claim 1 further comprising an adhesive disposed on at least a portion of the second side of the support base.
5. The device of claim 1 wherein a communication end of the needles extend into the central lumen of the delivery tube.
6. The device of claim 1 wherein at least two of the needles are configured in parallel.
7. The device of claim 1 wherein the at least two of the needles are configured in series.
8. The device of claim 6 wherein the flexible planar support base is circular having at least three openings for receiving at least three corresponding needles.
9. The device of claim 6 wherein the flexible planar support base is triangular having at least three openings for receiving at least three corresponding needles.
10. The device of claim 7 wherein the flexible planar support base is an elongated flexible base having at least six openings for receiving six needles.
11. A subcutaneous infusion device, comprising:
a flexible delivery tube including a central lumen, a closed first end and an open second end, the flexible delivery tube including a plurality of needle openings;
a rigid planar support base attached adjacent a first end of the delivery tube, the support base having a first side for supporting the flexible delivery tube and a second side positioned opposite the first side; and a plurality of needles each needle having a first portion having a communication end, the first portion disposed within the central lumen of the flexible delivery tube and a second portion having an open end for penetrating skin and delivering fluid from the central lumen to a subcutaneous tissue, the second portion perpendicular to the first portion and extending through one of the plurality of needle openings and extending substantially perpendicular to the support base and in communication with the central lumen of the delivery tube;
wherein the support base includes a plurality of openings aligned with the plurality of needle openings of the flexible delivery tube, each of the plurality of openings for receiving one of the plurality of needles and wherein the second side includes an adhesive layer for removably attaching the support base to a patient's skin.
12. The device of claim 11 further comprising a luer fitting attached to the second end of the delivery tube.
13. The device of claim 11 wherein the needles are sized to allow a flow rate of approximately 120 to 200 cc/hr.
14. The device of claim 11 further comprising an adhesive disposed on at least a portion of the second side of the support base.
15. The device of claim 11 wherein a communication end of the needles extend into the central lumen of the delivery tube.
16. The device of claim 11 wherein at least two of the needles are configured in parallel.
17. The device of claim 16 wherein the rigid planar support base is circular having at least three openings for receiving at least three corresponding needles.
18. The device of claim 16 wherein the rigid planar support base is triangular having at least three openings for receiving at least three corresponding needles.
19. The device of claim 11 wherein the at least two of the needles are configured in series.
20. The device of claim 11 wherein the rigid planar support base is an elongated rigid base having at least four openings each for receiving one of four needles.
