Insulin patch pump
A user-wearable patch pump system for delivery of insulin or other medicament can include a pump and an attachment portion that attaches the pump to a user's body. The pump can include a drive unit and a disposable cartridge containing a medicament with the drive unit configured to cause the pump to deliver the medicament in the cartridge to the user. The attachment portion can include a retention frame configured to selectively retain the pump therein and an adhesive patch configured to be attached to the user's body. The pump can be selectively attached to the retention frame and used to deliver medicament through tubing to an infusion site displaced from the pump.
1. A user-wearable infusion pump system, comprising:
a user-wearable pump including a drive unit and a disposable cartridge selectively attachable to the drive unit, the disposable cartridge configured to contain a medicament and the drive unit configured to cause the pump to deliver the medicament to a user, the user-wearable pump defining an outer perimeter of the user-wearable pump;
a retention frame configured to selectively retain the user-wearable pump therein, the retention frame including a bottom surface and an outer rim extending upwardly from an outer perimeter of the bottom surface, wherein the outer rim is configured to at least partially surround the outer perimeter of the user-wearable pump when the user-wearable pump is retained in the retention frame;
tubing configured to extend between the user-wearable pump and an infusion site displaced from a location of the retention frame; and
a button disposed on the outer perimeter of the user-wearable pump, the button configured to selectively cause the drive unit to cause the pump to deliver a predetermined quantity of medicament when the button is pressed and accessible when the user-wearable pump is retained in the retention frame;
wherein the pump is configured to selectively be put into fluid communication with the tubing to selectively deliver the medicament to the infusion site.
2. The system of claim 1 , wherein the pump is slidably received by the retention frame.
3. The system of claim 1 , wherein the tubing is integrally attached to the pump.
4. The system of claim 1 , wherein the tubing is integrally attached to the disposable cartridge.
5. The system of claim 1 , wherein the button is disposed on the drive unit.
6. The system of claim 1 , further comprising an adhesive patch affixed to the retention frame and configured to be adhered to the user.
7. The system of claim 1 , wherein the outer rim is configured to extend around an entire outer perimeter of the user-wearable pump when the user-wearable pump is retained in the retention frame.
8. The system of claim 1 , wherein the outer rim includes a pump retainer extending therefrom, the pump retainer configured to releasably retain the user-wearable pump.
9. The system of claim 8 , wherein the pump retainer comprises a pair of tabs extending from the outer rim configured to selectively engage corresponding recesses on the pump to retain the pump on the retention frame.
10. The system of claim 9 , wherein a first of the pair of tabs comprises a hook portion and a second of the pair of tabs comprises a snap portion, and the pump is configured to be retained within the retention frame by engaging a first recess of the pump with the hook portion and then engaging a second recess of the pump with the snap portion.
11. The system of claim 8 , wherein the pump retainer includes one or more elongate tabs that are slidably received within one or more corresponding elongate recesses in the pump.
12. The system of claim 1 , wherein the button is accessible when the user-wearable pump is retained in the retention frame because the button is disposed above the outer rim of the retention frame.
13. The system of claim 1 , wherein the button is accessible when the user-wearable pump is retained in the retention frame through an opening in the outer rim of the retention frame.
14. A user-wearable infusion pump system, comprising:
a user-wearable pump including a drive unit and a disposable cartridge selectively attachable to the drive unit, the disposable cartridge configured to contain a medicament and the drive unit configured to cause the pump to deliver the medicament in the cartridge to a user, the user-wearable pump defining an outer perimeter of the user-wearable pump;
a retention frame configured to selectively retain the user-wearable pump therein, the retention frame including a bottom surface and an outer rim extending upwardly from an outer perimeter of the bottom surface, wherein the outer rim is configured to at least partially surround the outer perimeter of the user-wearable pump when the user-wearable pump is retained in the retention frame;
tubing configured to extend between the user-wearable pump and an infusion site displaced from a location of the retention frame; and
a button disposed on an outer perimeter of the user-wearable pump, the button configured to selectively cause the drive unit to cause the pump to deliver a predetermined quantity of medicament when the button is pressed and accessible when the user-wearable pump is retained in the retention frame.
15. The system of claim 14 , wherein the tubing is integrally attached to the pump.
16. The system of claim 15 , wherein the tubing is integrally attached to the disposable cartridge.
17. The system of claim 14 , further comprising an adhesive patch affixed to the retention frame and configured to be adhered to the user.
18. The system of claim 14 , wherein the outer rim is configured to extend around an entire outer perimeter of the user-wearable pump when the user-wearable pump is retained in the retention frame.
19. The system of claim 14 , wherein the outer rim includes a pump retainer extending therefrom, the pump retainer configured to releasably retain the user-wearable pump.
20. The system of claim 19 , wherein the pump retainer includes one or more elongate tabs that are slidably received within one or more corresponding elongate recesses in the pump.
21. The system of claim 14 , wherein the button is accessible when the user-wearable pump is retained in the retention frame because the button is disposed above the outer rim of the retention frame.
22. The system of claim 14 , wherein the button is accessible when the user-wearable pump is retained in the retention frame through an opening in the outer rim of the retention frame.
