An apparatus, comprising, a cochlear implant electrode array, and an implantable drug reservoir, wherein the apparatus is configured such that the drug reservoir is in fluid communication with the electrode array, and the drug reservoir is at least substantially located in a middle ear space when the cochlear implant electrode array is fully implanted in a recipient.

An infusion pump comprises an elastomeric hemispheric deformable rolling diaphragm, an external rigid housing with internal area no greater than that of the rolling diaphragm exterior, and a rigid cap structure which sealingly fastens the rim of the rolling diaphragm to the rim of the external housing. Thickness of the flexing wall of the diaphragm is tapered from rim to a region on the central axis to provide approximately constant pressure as the pump empties its contents. The rigid housing has an port in its center opposite its rim to allow insertion of fluid to roll the diaphragm inward, and to allow outflow of the stored pressurized fluid as desired. The housing and/or cap structure may have an external belt mounting fixture to facilitate donning the infusion pump for ambulatory users. The simplified design enables low manufacturing cost and hence single-use disposability.

[Problem] The purpose of the present invention is to provide a portable anticancer agent container for preventing exposure and infection to the human body caused by chemical solution leakage that arises during a removal operation of a coupling connector at the time of system cleaning using a cleaning solution. [Solution] Provided is a pressurization-type drug injector having a drug exposure preventive function and having a system cleaning function, the pressurization-type drug injector comprising: a reservoir that has a chemical solution filling opening and a chemical solution discharging opening; a pressurization deformation means that undergoes pressurization and deformation by the injection of a chemical solution and that pushes out the chemical solution by a force caused by restoration of the pressurization and deformation; a flow rate control means that adjusts the flow rate of the chemical solution by resistance; a system cleaning port that includes a cleaning solution injection opening, a chemical solution filling opening, and a liquid discharging opening; and a case that contains therein said reservoir, said pressurization deformation means, and said system cleaning port. The case has openings respectively in the vicinity of the chemical solution filling opening, the system cleaning injection opening, and the chemical solution discharging opening. The chemical solution being filled is filled into the pressurization deformation means from the chemical solution filling opening of the reservoir, and moves from the chemical solution discharging opening of the reservoir to the exterior of the container via the flow rate control means. A cleaning solution is injected from the injection opening of the cleaning port arranged downstream from the flow rate control means, and moves to the exterior of the container. The pressurization-type drug injector having a drug exposure preventive function is characterized in that the periphery of the cleaning port is completely covered by a sterile seal, and thus, the cleaning port injection opening is kept clean until use.

The problem of infusing air into IV tubing and into a patient from a IV fluid bag inside a pressure infusion cuff is solved by collar embodiments that inhibit the air from being forced into the IV tubing. A collar can include one or more curved arms that create a channel in which that part of the fluid bag is protected against being squeezed by a pressure infusion cuff. A collar allows the fluid bag to be squeezed by the pressure infusion cuff until such time that the fluid level is sufficiently reduced that the collar can inhibit further pressure on the fluid bag by the pressure infusion cuff. Also disclosed is a fluid bag and a pressure infusion cuff that are modified to have a collar incorporated therewith.

Fill stations and base stations are provided for personal pump systems. The fill stations may be opened and closed to accept a reservoir and to allow fluid to be introduced into the reservoir for use with personal pump systems. The fill stations may hold the reservoir at a tilt relative to an underlying surface and may discourage overfilling of the reservoir. The filling stations may also include viewing windows having fluid lines marked thereon for indicating volume of fluid within the reservoir.

A system is disclosed. The system includes a reservoir for containing a fluidic medium, the reservoir including a front surface, a resilient cylindrical flexure portion connected to the front surface, the resilient cylindrical flexure portion comprising an accordion-like structure that is able to expand and contract to change an interior volume within the resilient cylindrical flexure portion, a central passageway within the resilient cylindrical flexure, and a collection chamber connected to the central passageway. Also, a system including a reservoir, a plunger head located within the reservoir, a plunger arm connected to the plunger head, a driving shaft connected to the plunger arm, and a motor connected to the driving shaft, the motor controllable to move the drive shaft in a first motion and a second motion so as to move the advance plunger head and retract the plunger head within the reservoir.

A device for dispensing fluid from a flexible bag includes a casing containing a tray for receiving a fluid-filled bag and a pressure applicator movable by an actuator. Movement of the actuator pushes the pressure applicator against the tray by translation or by rotation to compress the bag between the tray and the casing.

A cassette for attachment and use with an infusion pump apparatus. The cassette head having a low profile cassette head for attaching to the infusion pump apparatus and a flexible reservoir attached to the cassette head that can be filled with a fluid to be administered to a patient. The reservoir is enclosed in a flexible cover attached to the cassette. The flexibility of the cover and the reservoir inhibits the cassette head from disengaging from the infusion pump apparatus and allows the infusion pump apparatus to be primed by squeezing or pressing the cover and reservoir.

A fill adapter for filling a reservoir and a related method are disclosed herein. The fill adapter includes a button assembly actuator and a pump chamber plunger actuator hingably attached to the button assembly actuator, wherein the actuation of the button assembly actuator actuates the pump chamber plunger actuator and wherein the pump chamber plunger actuator actuates a pump chamber membrane before the at least one button assembly is actuated.
