A mold assembly includes a mold base plate and a mold. The mold base plate has a bottom plate located in a recess. The mold can be inserted into and removed from the recess and is located on top of the bottom plate. The mold has a first section that is separable from a second section. When the first section and the second section are located adjacent to each other in the recess, a plurality of cavities is formed, each cavity for receiving a quantity of a drug and compound mixture when the mold base plate and mold are at a temperature other than room temperature

An injection device includes a dispensing chamber, a plunger, a controller, a memory device resistant to sterilization, and a housing at least partially enclosing the dispensing chamber and the plunger. The dispensing chamber has an inner surface and an outer surface. The inner surface defines a cavity for receiving a quantity of a substance. The plunger is engaged with the inner surface of the dispensing chamber, is capable of sliding in the cavity of the dispensing chamber, and is fluidly sealed to the inner surface of the dispensing chamber. The controller controls the operation of the injection device. The controller reads dosage data from the memory device and operates the injection device to deliver a dosage corresponding to the dosage data.

A mold apparatus includes a container, a temperature control device, a distribution manifold, a plurality of dispensers, a mold, a bottom plate for the mold, and a vacuum chamber. The temperature control device at least partially surrounds the container. The distribution manifold is located downstream from the container. The plurality of dispensers are coupled to the distribution manifold. The mold has a plurality of cavities for receiving a mixture from the plurality of dispensers. The bottom plate is located on a bottom surface of the mold. The vacuum chamber keeps the container, distribution manifold, plurality of dispensers and mold in a vacuum. A drug and compound mixture are brought to a temperature other than room temperature and dispensed into the mold under a vacuum to form pellets.

An ophthalmic injection system has a tip segment attachable to and removable from a limited reuse assembly. The tip segment has a dispensing chamber housing, a plunger, a needle, a temperature control device, a thermal sensor, and a first housing at least partially enclosing the dispensing chamber housing, the temperature control device and the plunger. The limited reuse assembly has an actuator with a shaft, a power source for providing power to the actuator, a controller for controlling the actuator, a mechanical linkage interface, and a second housing at least partially enclosing the power source, the controller, and the actuator. The mechanical linkage interface is coupled to the actuator shaft and has a mating surface on one end. The substance is injected after the temperature of the substance is altered.

An ophthalmic injection system is disclosed. The system has a dispensing member, a plunger, an actuation chamber, a lock mechanism, a lock stop, a port, a source of pressurized gas, and a shaft. The lock mechanism travels in the actuation chamber in an axial direction toward and away from a distal end of the dispensing member. The lock stop is located on the inner surface of the actuation chamber. The lock stop is engageable with the lock mechanism such that when the lock mechanism travels in the axial direction toward the distal end of the dispensing member to a first position located on a distal side of the lock stop, the lock mechanism cannot travel in a reverse direction away from the distal end of the dispensing member to a location on a proximal side of the lock stop.

A dispensing assembly has a dispensing chamber housing, a temperature control device, a thermal sensor, and an interface. The dispensing chamber housing has an inner surface, an outer surface, and a wall thickness. The inner surface partially defines a dispensing chamber for receiving a quantity of a substance. The temperature control device at least partially surrounds the dispensing chamber housing. The temperature control device alters a temperature of a substance in the dispensing chamber. The temperature control device and the thermal sensor are located on a substrate. The substrate is wrapped around an exterior surface of the dispensing chamber housing. The interface is connected to the temperature control device and the thermal sensor. An interface connector is connected to the interface. The distance between the temperature control device and the thermal sensor is approximately equal to the wall thickness of the dispensing chamber housing.
摘要:
The present invention is an ophthalmic injection system with a limited reuse assembly and a tip segment. The tip segment is connectable to and removable from the limited reuse assembly. The tip segment includes a dispensing chamber, a plunger, and a housing. The dispensing chamber holds a quantity of a substance to be injected into an eye. The proximate end of the plunger has a first mechanical linkage interface. The limited reuse assembly of the ophthalmic injection system has a power source, a controller, a motor, a second mechanical linkage interface located on an end of the motor shaft; and a second housing. The first mechanical linkage interface is mateable with the second mechanical linkage interface such that when the tip segment is connected to the limited reuse assembly, the first mechanical linkage interface mates with the second mechanical linkage interface so that motion of the shaft results in motion of the plunger.
摘要:
An injection assembly includes a dispensing chamber housing, a temperature control device, a thermal sensor, a switch, and a controller. The dispensing chamber housing has an inner surface and an outer surface. The inner surface partially defines a dispensing chamber for receiving a quantity of a substance. The temperature control device at least partially surrounds the dispensing chamber housing and alters a temperature of a substance in the dispensing chamber. The thermal sensor is located near the temperature control device and reads a temperature near the temperature control device. The switch is coupled to the temperature control device. The controller controls the temperature control device and the switch such that a first voltage is applied to the temperature control device until the temperature control device reaches a desired temperature, and a second voltage is applied to the temperature control device thereafter to maintain the temperature control device at the desired temperature.

A drug retention cap has a cap section and a drug retention pin. The cap section has a generally dome-shaped top end and a cylindrical portion extending downward from the generally dome-shaped top end. The top end of the cap section is closed, and the bottom end is open. The open bottom end is configured to receive a needle of a drug delivery device. The drug retention pin extends from near the apex of the dome-shaped top end downward toward the open bottom end. The drug retention pin is configured to fit inside a hollow needle.
