Abstract

Embodiments of the present disclosure relate to techniques, processes, devices or systems for pump devices. In one approach, a wearable drug delivery device may include a reservoir configured to store a liquid drug, the reservoir including a housing including an outer wall defining an interior chamber, a sealing member, and a slit through the housing, wherein the sealing member is configured to seal the slit. The wearable drug delivery device may further include a delivery pump device including a drive mechanism coupled to the reservoir for driving the liquid drug out of the reservoir, the drive mechanism including a piston head disposed within the interior chamber of the housing, and a lead screw coupled to a drive nut, wherein the drive nut comprises a blade adjacent the piston head, and wherein the blade is positionable through the slit of the housing.

Claims (39)

1 . A wearable drug delivery device, comprising:

a reservoir configured to store a liquid drug, the reservoir comprising:

a housing including an outer wall defining an interior chamber;

a sealing member; and

a slit through at least a portion of the housing, wherein the sealing member seals the slit; and

a delivery pump device including a drive mechanism coupled to the reservoir for driving the liquid drug out of the reservoir, the drive mechanism comprising:

a piston head disposed within the interior chamber of the housing; and

a lead screw coupled to a drive nut, wherein the drive nut comprises a blade adjacent the piston head, and wherein the blade is within the slit of the housing and configured to move within the slit to cut the sealing member, wherein an entirety of the slit and an entirety of the blade are contained within the reservoir.

2 . The wearable drug delivery device of claim 1 , the housing of the reservoir comprising a core shaft within the interior chamber, wherein the sealing member is formed along an exterior surface of the core shaft, and wherein the lead screw of the drive mechanism extends within an interior of the core shaft.

3 . The wearable drug delivery device of claim 2 , wherein the slit is formed through the core shaft.

4 . The wearable drug delivery device of claim 2 , wherein the piston head includes a first sealing ring extending about an outer surface and a second sealing ring extending about an interior surface, and wherein the second sealing ring is in direct physical contact with the sealing member formed along the exterior surface of the core shaft.

5 . The wearable drug delivery device of claim 1 , wherein the blade of the drive nut extends perpendicular to or radially outward from the lead screw, and wherein the blade of the drive nut is in direct physical contact with an outer face of the piston head.

6 . The wearable drug delivery device of claim 1 , wherein the sealing member is a polyethylene film.

7 . A wearable drug delivery device, comprising:

a reservoir configured to store a liquid drug, the reservoir comprising:

a housing including an outer wall defining an interior chamber;

a sealing member; and

a slit through at least a portion of the housing, wherein the sealing member seals the slit; and

a delivery pump device including a drive mechanism coupled to the reservoir for driving the liquid drug out of the reservoir, the drive mechanism comprising:

a piston head disposed within the interior chamber of the housing; and

a lead screw coupled to a drive nut, wherein the drive nut comprises a blade adjacent the piston head, wherein the blade is within the slit of the housing and configured to move within the slit to cut the sealing member, wherein an entirety of the slit and an entirety of the blade are contained within the reservoir, and wherein the lead screw has external threading engaged with corresponding internal threading of the drive nut, and wherein rotation of the lead screw causes the blade to move axially along the lead screw.

8 . The wearable drug delivery device of claim 7 , the housing of the reservoir comprising a core shaft within the interior chamber, wherein the sealing member is formed along an exterior surface of the core shaft, wherein the lead screw of the drive mechanism extends within an interior of the core shaft, and wherein the slit is formed through the core shaft.

9 . The wearable drug delivery device of claim 8 , wherein the piston head includes a first sealing ring extending about an outer surface and a second sealing ring extending about an interior surface, wherein the second sealing ring is in direct physical contact with the sealing member formed along the exterior surface of the core shaft.

10 . The wearable drug delivery device of claim 7 , wherein the blade of the drive nut extends perpendicular to the lead screw, and wherein the blade of the drive nut is directly adjacent an outer face of the piston head.

11 . A method, comprising:

providing a reservoir configured to store a liquid drug, the reservoir comprising:

a housing including an outer wall defining an interior chamber;

a sealing member; and

a slit through the housing, wherein the sealing member seals the slit;

coupling a drive mechanism of a delivery pump device to the reservoir, the drive mechanism comprising:

a piston head disposed within the interior chamber of the housing; and

a lead screw coupled to a drive nut, wherein the drive nut comprises a blade adjacent the piston head, and wherein the blade is within the slit of the housing and configured to move within the slit to cut the sealing member, wherein an entirety of the slit and an entirety of the blade are contained within the reservoir; and

rotating the lead screw to cause the drive nut to move axially along the lead screw between a first position and a second position to force the liquid drug out of the reservoir.

12 . The method of claim 11 , further comprising:

providing the sealing member along an exterior surface of a core shaft of the housing, wherein the slit is formed through the core shaft; and

cutting through the sealing member with the blade of the drive nut as the drive nut moves between the first position and the second position.

13 . The method of claim 12 , further comprising positioning the lead screw of the drive mechanism within an interior of the core shaft.

14 . The method of claim 12 , further comprising providing a first sealing ring about an outer surface of piston head and providing a second sealing ring about an interior surface of the piston head, wherein the second sealing ring is in direct physical contact with the sealing member formed along the exterior surface of the core shaft.

15 . The method of claim 11 , further comprising positioning the blade of the drive nut in direct physical contact with an outer face of the piston head, wherein the axial movement of the drive nut causes the piston head to move within the interior chamber of the housing.
