Medical apparatus remote control and method

A device (10) for delivering fluid to a patient including a passageway having a proximal fluid transport tube, a distal fluid transport tube, and a tubular expansion member coupling the fluid transport tubes. A penetrating member (704) is positioned within the expansion member for axial movement between the fluid transport tubes, and has a sharpened distal tip. The device also includes a dispenser (40) for causing fluid from a reservoir (30) to flow to the proximal fluid transport tube, a housing (20) containing the dispenser and the passageway and including an exit port (70) receiving the distal fluid transport tube, and a connecting member secured to the penetrating member. The connecting member is movable by a user from an exterior of the housing and arranged such that movement causes the penetrating member to move between an extended position and a retracted position.

Transcutaneous delivery means

A medicament delivery device (10) has a reservoir within a housing (11) and means for driving medicament from the reservoir. The device is provided with a filling mechanism upon which a medicament container (19) sealed by a penetrable stopper (25) is mounted. The mechanism comprises an internal bore (20) which accommodates an internal rod (21) from which a needle (22) projects. Needle (22) is hollow and is in communication with the reservoir. In order to fill the reservoir, the container (19) is pressed into the bore (20), causing the needle (22) to pierce the stopper (25), the stopper abutting against the rod (21) and acting as a piston to drive medicament from the container (19) as the container (19) is pushed into the bore (20) and moves relative to the stopper (25). Thus, the reservoir can be filled with the sterile medicament which is stable when stored in the container (19), and the filling is easily accomplished without the use of a syringe. A further advantageous feature is provided by a delivery needle which is mounted on the periphery of the lower surface of the housing. This configuration allows the driving means to be located adjacent to the skin, thereby, providing a more stable temperature and more predictable operation of the device.

Medicament delivery device

This invention is an apparatus (10) for accurately infusing fluids into a patient at specific rates over an extended period of time. The apparatus (10) is of a low profile, laminate or layered construction having a stored energy source in the form of a distended membrane (28), which in cooperation with the base (12) of the apparatus (10), defines one or more fluid reservoirs (20), each having a fluid inlet (22) and a fluid outlet (32). The apparatus further includes a novel conformable ullage made of yielding materials which uniquely conform to the shape of the elastomeric membrane (28) as the membrane (28) returns to its less distended configuration. This arrangement will satisfy even the most stringent medicament delivery tolerance requirements, and will elegantly overcome the limitations of materials selection encountered in devices embodying solely a rigid ullage construction. Additionally, in one form of the invention, the apparatus includes a novel fill assembly (302) for controllably filling the reservoirs of the device in the field.

Fluid delivery device with bolus injection site

This invention is a fluid delivery apparatus for continuous basal infusion, together with controlled bolus infusion of injectable medicaments, which embodies a stored energy source (66), such as distensible elastomeric membrane, which cooperates with a base and a conformable ullage to define a fluid reservoir.

Fluid delivery device with conformable ullage and fill assembly

An apparatus (30) for accurately infusing medicinal agents into an ambulatory patient at specific rates over extended periods of time. The apparatus (30) is of a compact, low profile laminate construction and includes an elastic distendable membrane (34), which, in cooperation with a thin planar base (32) defines a fluid chamber (46) having a fluid outlet. Disposed within the fluid chamber (46) is a thin fluid permeable member (66) which precisely controls the rate of fluid flow through the fluid outlet. The apparatus (30) also includes a highly novel fluid flow indicator (104) that provides a readily discernible visual indication of fluid flow through the apparatus (30).

Fluid delivery apparatus and method of making same

An apparatus for accurately infusing fluids into a patient at specific rates over an extended period of time. The apparatus is of a low profile, laminate or layered construction having a stored energy source in the form of a distendable membrane, which, in cooperation with the base of the apparatus, defines one or more fluid reservoirs, each having a fluid inlet and a fluid outlet. The apparatus further includes, a high novel, conformable ullage made of yieldable materials. The conformable ullage uniquely conforms to the shape of elastomeric membrane as the membrane returns to its less distended configuration. Additionally, the infusion cannula of the apparatus is connected to the base in a novel manner which permits expeditious subdermal delivery to the patient via a cannula which extends generally perpendicularly relative to the base. The cannula is connected to the base in a manner such that the pierceable portion of the cannula is free to move relative to the base of the device in response to movements by the patient which cause flexing of the muscle and tissue in the vicinity of the cannula.

Subdermal delivery device

An apparatus for accurately infusing fluids into a patient at specific rates over an extended period of time. The apparatus is of a low profile, laminate or layered construction having a stored energy source in the form of a distendable membrane, which, in cooperation with the base of the apparatus, defines one or more fluid reservoirs, each having a fluid inlet and a fluid outlet. The apparatus further includes, a novel conformable ullage made of yieldable materials. The conformable ullage uniquely conforms to the geometry of elastomeric membrane as the membrane returns to its less distended configuration and in so doing can move between a central chamber and a toroidal chamber formed in the cover of the apparatus. This arrangement will satisfy even the most stringent medicament delivery tolerance requirements and will elegantly overcome the limitations of materials selection encountered in devices embodying solely a rigid ullage construction. Additionally, the infusion cannula of the apparatus is connected to the base in a novel manner which permits expeditious subdermal delivery to the patient via a cannula which extends generally perpendicularly relative to the base.
