Abstract

Described is a housing for a drug infusion pump. Generally, the housing is of a hybrid design having a rigid portion containing the drive mechanism and any desired electronic components, and a pliant portion that improves the adherence of the patch-style infusion device to the body of the patient.

Claims

1. A medical infusion device, comprising:

a rigid housing having a top portion, a base portion, and a cavity;

an inline drive mechanism within the cavity;

a reservoir in fluid communication with the inline drive mechanism;

a fluid outlet port in fluid communication with the inline drive mechanism,

wherein the fluid outlet port extends through the housing;

one or more pliant portions depending from the rigid housing; and

an adhesive patch attached to at least the base portion of the rigid housing.

2. The medical device of claim 1 wherein the reservoir is in fluid communication with the inline drive mechanism via one or more fluid channels.

3. The medical infusion device of claim 1, comprising a receiver mechanism for releasably attaching a cannula or a lineset to the fluid outlet port.

4. The medical infusion device of claim 3, wherein the receiver mechanism comprises one or more finger-press tabs.

5. The medical infusion device of claim 4, wherein the one or more finger-press tabs each are in mechanical communication with at least one catch-tab.

6. The medical infusion device of claim 5, wherein the one or more finger-press tabs each are in mechanical communication with at least one latch-tab.

7. The medical infusion device of claim 6, wherein the receiver mechanism is attached to a cartridge configured to fit in the cavity.

8. The medical infusion device of claim 7, wherein the inline drive mechanism is disposed within the cartridge.

9. The medical infusion device of claim 8, wherein the reservoir is within the cartridge.

10. The medical infusion device of claim 8, wherein at least one of the one or more pliant portions depending from the housing having a cavity therein.

11. The medical infusion device of claim of claim 10, wherein the cavity in the at least one of the one or more pliant portions depending from the housing comprises the reservoir.

12. The medical infusion device of claim 7 wherein the cartridge is releasably secured in the housing by the latch tabs.
