A sterile drug dispensing system, comprising: an air source output device, a handle and a drug dissolving device; the drug dissolving device is detachably mounted on the handle, the handle being connected to the air source output device by means of a power line and an air pipe, being for use in filtering gas and controlling the gas source output device; the gas source output device is used for outputting and extracting gas. A sterile drug dispensing method, which corresponds to the operating steps of the sterile drug dispensing system.

An implantable, gas pressure-operated infusion pump includes a throttle portion, a controllable valve upstream or downstream of the throttle portion, and a controller that controls the opening duration and/or opening frequency of the valve. A method for operating the infusion pump includes determining a standard volume of a standard infusate dispensed by the infusion pump within a pre-determined time period and determining an infusate volume of an infusate, having a different composition than the standard infusate, dispensed by the infusion pump within the pre-determined time period. The method further includes operating the infusion pump together with the infusate at an opening duration and/or opening frequency of the valve that is reduced or increased compared with operating the infusion pump together with the standard infusate in order to dispense a volume of infusate substantially the same as the standard volume.

A wearable drug delivery device includes a housing, a needle assembly at least partially disposed in the housing, and a drive assembly at least partially disposed in the housing and coupled to the needle assembly. The needle assembly includes a needle or cannula and a sterile barrier disposed proximal to the needle or cannula in a first configuration where the sterile barrier is intact. The drive assembly includes a container that contains a medicament to be administered, a first plunger disposed in the container, and a drive mechanism that forces the first plunger to urge the medicament through the container. Upon engaging the drive mechanism, the needle or cannula and the sterile barrier move relative to each other from the first configuration to a second configuration where the needle or cannula breaks the sterile barrier, thereby allowing the medicament to be administered via the needle or cannula.

An automatic fluid injection device having a body fastened to a support for coming into contact with an injection zone, the body containing one or more fluid reservoirs each containing an injection piston; a needle assembly including an injection needle for penetrating into the injection zone; and an injection mechanism. The injection mechanism having an actuator cap containing an expandable material, and a heater mechanism for heating the expandable material, thus causing it to expand so as to move the piston in the reservoir, and thus inject the fluid into the injection zone through the injection needle. The expandable material has thermally expandable microspheres.

Embodiments of the invention provide swallowable devices, preparations and methods for delivering drugs and other therapeutic agents within the GI tract. Particular embodiments provide a swallowable device such as a capsule for delivering drugs into the intestinal wall or other GI lumen. Embodiments also provide various drug preparations that are configured to be contained within the capsule, advanced from the capsule into the intestinal wall and degrade within the wall to release the drug to produce a therapeutic effect. The preparation can be coupled to a delivery mechanism having one or more balloons or other expandable devices which are expandable responsive to a condition in the small intestine or other GI lumen to advance the preparation out of the capsule into the intestinal wall. Embodiments of the invention are particularly useful for the delivery of drugs which are poorly absorbed, tolerated and/or degraded within the GI tract.

A disclosed drip chamber for an intravenous (IV) therapy system includes a container configured to hold an IV fluid, a drop former suspended over the container, and an inlet port disposed above the drop former and configured to receive the IV fluid from a reservoir. The drop former has an upper end, a lower tip, and an outer surface extending between the upper end and the lower tip. The inlet port is coupled to the outer surface to permit the IV fluid to descend down the outer surface.
