Simplified and/or one-handed use of a patch injector

Abstract

A wearable medical device may be unpacked, prepared, and/or used while being grasped with a single hand position. For example, the device may be removed from a package, primed, and/or adhered to the skin of a user while being grasped with the single hand position. Optionally, the device may be used with a single hand. Optionally, the device includes a delivery interface (for example, including a needle tip and/or a skin contact surface). Optionally, the device includes a protector that preserves sterility of the delivery interface. Optionally, the cover can be removed with a single hand. Optionally, removal of the cover is performed with the same hand position as placement of the device on a delivery site.

We claim: 
     
         1 . A kit for one-handed delivery of a drug to a subject comprising:
 a wearable drug delivery device including an adhesive contact surface configured to adhere the device to a skin of the subject and a grip including opposing gripping surfaces, each of said opposing gripping surfaces being at an angle of between 30 and 150 degrees to said contact surface;   a user interface located between said gripping surfaces; and   a package holding said device, the package having a body and a closure hingedly connected to the body, wherein said adhesive contact surface is facing into, and shielded by, said body and said gripping surfaces are shielded by said closure in a closed state of the package, and wherein opening of the package via removal of said closure exposes said gripping surfaces while said drug delivery device remains at least partially inside the body and said adhesive contact surface remains shielded by said body.   
     
     
         2 . The kit of  claim 1 , wherein said closure is configured for one handed removal from said package and shields said adhesive contact surface. 
     
     
         3 . The kit of  claim 1 , wherein said packaging includes a base configured to sit stably on a flat horizontal surface while said user interface is angled between 10 to 50 degrees of said base. 
     
     
         4 . The kit of  claim 1 , wherein said packaging includes a space for inserting a finger between said package and each of said gripping surfaces. 
     
     
         5 . The kit of  claim 1 , further comprising an orientation indicator visible from outside the package for orienting said delivery device for grasping the grip while the device is still inside the package. 
     
     
         6 . The kit of  claim 1 , wherein said delivery device includes a delivery interface, the kit further comprising a sterility protecting cover, separating between said delivery interface and said grip. 
     
     
         7 . The kit of  claim 6 , wherein said delivery interface includes a sterile needle tip and said protective cover includes a needle cover. 
     
     
         8 . The kit of  claim 7 , wherein said needle tip is concealed behind said adhesive contact surface. 
     
     
         9 . A kit comprising:
 a wearable drug delivery device including a removable grip for holding a device with a palm of a hand facing the device;   an adhesive contact surface on a side of said device opposite said grip, said adhesive contact surface configured to adhere the device to a skin surface of the subject, said grip extending away from the device, when attached thereto, from a side opposite said adhesive contact surface; and   a package holding said device with said adhesive contact surface shielded by said package while said grip is exposed, said package including a guide encouraging a user to hold said grip with a preferred finger.   
     
     
         10 . The kit of  claim 9 , wherein said grip is sized and shaped to be held by a subset of digits of a hand. 
     
     
         11 . The kit of  claim 10 , wherein the wearable drug delivery device further includes a user interface sized and shaped to be controlled by a free digit of said hand while said subset of digits hold said grip. 
     
     
         12 . The kit of  claim 9 , wherein the wearable drug delivery device further includes a priming interface protruding from said skin contact surface.
