Abstract
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 either through a cannula to an infusion site directly beneath the retention frame or through tubing to an infusion site displaced from the retention frame.
Core Innovation
The invention relates to a user-wearable infusion pump system configured to contain a medicament. A user-wearable infusion pump includes a button disposed on an outer perimeter that selectively initiates a medicament delivery operation when the button is pressed, and the system includes a retention frame configured to selectively retain the user-wearable infusion pump therein.
The retention frame includes a frame base with a first side, an opposing second side, a first end, and an opposing second end defining a frame perimeter shaped to generally match the outer perimeter of the user-wearable infusion pump. A retention wall extends upwardly from the frame base around an entirety of the frame perimeter to contact and limit horizontal movement of the user-wearable infusion pump relative to the retention frame, and a retention member extends inwardly from the frame perimeter to interface with an upwardly facing surface of the user-wearable infusion pump and to limit vertical movement relative to the retention frame.
An opening disposed adjacent the frame perimeter enables access to the button disposed on the outer perimeter when the user-wearable infusion pump is disposed on the frame base. The disclosed system additionally supports medicament delivery flexibility by using either an on-frame cannula infusion site or tubing to a displaced infusion site, and it can include optional remote control using a remote device to control pump operation.
Claims Coverage
The partial document includes two independent claims. Across these independent claims, there are core mechanical-integration features: button accessibility via an opening, horizontal limitation via an upward retention wall, and vertical limitation via an inward retention member.
User-wearable infusion pump with periphery button initiating delivery
A user-wearable infusion pump configured to contain a medicament, including a button disposed on an outer perimeter configured to selectively cause the user-wearable infusion pump to initiate a medicament delivery operation when the button is pressed.
Retention frame perimeter matching outer pump perimeter
A retention frame configured to selectively retain the user-wearable infusion pump therein, the retention frame including a frame base having a first side and an opposing second side and a first end and opposing second end defining a frame perimeter having a shape generally matching the outer perimeter of the user-wearable infusion pump.
Upward retention wall limiting horizontal movement
A retention wall extending upwardly from the frame base around an entirety of the frame perimeter to contact and limit horizontal movement of the user-wearable infusion pump relative to the retention frame.
Inward retention member limiting vertical movement
A retention member extending inwardly from the frame perimeter, the retention member configured to interface with an upwardly facing surface of the user-wearable infusion pump to limit vertical movement of the user-wearable infusion pump relative to the retention frame.
Opening adjacent frame perimeter enabling button access while retained
The button is accessible when the user-wearable infusion pump is retained in the retention frame through an opening disposed adjacent the frame perimeter.
Retention frame configured to enable button access when pump is disposed on frame base
A retention frame for selectively retaining a user-wearable infusion pump, comprising a frame base, a retention wall extending upwardly from the frame base around an entirety of the frame perimeter to contact and limit horizontal movement, and a retention member extending inwardly from the frame perimeter configured to interface with an upwardly facing surface of the user-wearable infusion pump to limit vertical movement, wherein an opening disposed adjacent the frame perimeter is configured to enable access to a button disposed on an outer perimeter of the user-wearable infusion pump when the user-wearable infusion pump is disposed on the frame base.
Overall, the independent-claim coverage centers on a retention-frame integration that constrains both horizontal and vertical movement while preserving user access to a periphery button through an opening adjacent the frame perimeter.
Stated Advantages
Limits horizontal movement of the user-wearable infusion pump relative to the retention frame.
Limits vertical movement of the user-wearable infusion pump relative to the retention frame.
Enables access to the button disposed on the outer perimeter while the user-wearable infusion pump is retained in the retention frame.
Documented Applications
User-wearable infusion pump system for medicament delivery operation using a medicament-containing user-wearable infusion pump retained in a retention frame with button access.
Delivery flexibility for medicament delivery using either an on-frame cannula infusion site or tubing to a displaced infusion site.
Optional remote control of pump operation using a remote device.
