Abstract
A self-contained body mounted pump assembly for continuously administering a therapeutic agent parenterally. The pump has a transparent top through which the contents can be seen and outwardly flaring sides to provide for comfort, stability and other useful features. The pump assembly is driven by a fluid imbibing, preferably osmotic pump and contains its own source of actuating fluid. Means for superimposing a pulse dose on the tonic flow are also described.

8. A pump assembly adapted to be mounted on the body of a subject comprising, in combination:
-
(a) pump housing means, said housing means comprising; (i) internal receptacle means defined by the internal top and side surfaces of said housing; (ii) exterior top and side surfaces; (iii) an exterior bottom surface at the bottom, body proximal end of said exterior side surface; and (iv) passageway means extending through said housing and terminating at one end proximate the internal top surface of said receptacle means and at another end proximate the bottom end of said exterior side surface; (b) an expansible, fluid impermeable membrane disposed within said receptacle means, dividing said receptacle means into upper and lower portions; (c) fluid imbibing pump means in said lower portion, said pump means having outlet means in fluid communicating relationship with said membrane; and (d) sealing means providing a fluid tight seal between said membrane, said fluid imbibing pump means and said housing means, whereby material discharged from said outlet means will be confined between said fluid imbibing pump means and said membrane. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A body mounted pump assembly comprising in combination
(a) a housing having outer top and side walls, said side walls flaring outwardly from said top wall whereby the circumference of the base of said housing is greater than the top of said housing; -
(b) receptacle means, defined within said housing and disposed below said top wall, the side surface of said receptacle means being provided with a circumferential shoulder, dividing said receptacle means into an upper and a lower portion, (c) a fluid imbibing pump disposed in said lower portion of said receptacle with its outlet directed towards said upper portion (d) means for maintaining said fluid imbibing pump in fluid sealing relationship to said shoulder and (e) passageway means extending through said side wall from a point proximate its lower outer end into the upper portion of said receptacle means. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43)

47. A pump assembly adapted to be mounted on the body of the subject said assembly comprising, in combination:
-
(a) internal receptacle means open at the bottom, body proximal, end of said housing, said receptacle being defined by internal top and side surfaces; (b) exterior top and side surfaces, said exterior side surface tapering downwardly from said top surface; (c) an exterior bottom surface at the body proximal end of said exterior side surface, (d) passageway means extending through said housing and terminating at one end proximate the internal top surface of said receptacle means and at another end proximate the body proximal end of said exterior side surface; (e) fluid imbibing pump means within said internal receptacle means said fluid imbibing pump means having an outlet in fluid communication with said passageway means; (f) means for maintaining fluid tight seal between the exterior of said fluid imbibing pump means and the internal surface of said receptacle means; and (g) a source of activating fluid for said fluid imbibing pump said source of said activating fluid being received within said receptacle and in contact with the exterior surface of said fluid imbibing pump means;
whereby said activating fluid may be imbibed into said fluid imbibing pump means and the flud discharged through the outlet of said fluid imbibing pump means will flow out of said pump assembly through said passageway means. - View Dependent Claims (48)
