SKIN SECURABLE INFUSION ASSEMBLY AND METHOD OF USE
First Claim
1. A skin securable infusion assembly, comprising:
- a housing having a skin contacting adhesive layer and supporting an infusion cannula;
an elongate tubular reservoir having a plunger slidably disposed therein, wherein the reservoir is configured to contain a supply of liquid medication between a distal opening of the reservoir and the plunger, wherein the reservoir has an assembled configuration in which the reservoir is supported on the housing; and
an actuation mechanism coupled with the plunger, wherein, in the assembled configuration, an actuation of the actuation mechanism moves the plunger toward the distal opening and forces a portion of the liquid medication through the distal opening and into the infusion cannula.

Abstract
A skin securable infusion assembly includes a housing having a skin contacting adhesive layer and supporting an infusion cannula. An elongate tubular reservoir having a plunger slidably disposed therein is configured to contain a supply of liquid medication between a distal opening of the reservoir and the plunger. The reservoir has an assembled configuration in which the reservoir is supported on the housing. An actuation mechanism is coupled with the plunger and, when the reservoir is in the assembled configuration, an actuation of the actuation mechanism moves the plunger toward the distal opening and forces a portion of the liquid medication through the distal opening and into the infusion cannula.

11. A method of administering a liquid medication using a skin securable infusion assembly, wherein the skin securable infusion assembly includes a housing having a skin contacting adhesive layer and supporting an infusion cannula, an elongate tubular reservoir having a plunger slidably disposed therein, wherein the reservoir is supported on the housing and contains a supply of liquid medication between a distal opening of the reservoir and the plunger, and an actuation mechanism coupled with the plunger, the method comprising steps of:
-
adhering the adhesive layer of the housing to skin of a patient; inserting the infusion cannula beneath the skin; and administering a discrete dosage of the liquid medication to the patient by moving the plunger toward the distal opening using an actuation mechanism coupled with the plunger and forcing the discrete dosage of the liquid medication through the distal opening and into the infusion cannula. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A disposable reservoir for a skin securable infusion assembly, wherein the skin securable infusion assembly includes a housing having a skin contacting adhesive layer and supporting an infusion cannula, the disposable reservoir comprising:
-
an elongate tubular reservoir having a spiral configuration, wherein a distal opening of the reservoir is adapted for mating engagement with the infusion cannula and a proximal opening of the reservoir is adapted for mating engagement with an actuation mechanism; a plunger slidably disposed within the reservoir and movable in response to actuation of the actuation mechanism; and a supply of liquid medication contained within the reservoir between the distal opening of the reservoir and the plunger. - View Dependent Claims (20)
