An aqueous preparation containing a protein as an active ingredient which is stable in storage in solution and makes an injection pain reduced is provided. More specifically an aqueous preparation containing a phosphate buffer at a concentration of 1 to 20 mM and a protein as an active ingredient is provided. Further more specifically provided is an aqueous preparation containing a phosphate buffer at a concentration of 1 to 20 mM, human growth hormone as an active ingredient, a poloxamer as a non-ionic surfactant; and phenol as a isotonic agent.

Protein-containing aqueous liquid formulation

A pharmaceutical cartridge holding unit holds a pharmaceutical cartridge and is mounted to a pharmaceutical injection device main body in order to mount the pharmaceutical cartridge to a pharmaceutical injection device. The pharmaceutical cartridge holding unit comprises an outer peripheral cap having a front end side opening and a rear end side opening, and a cartridge cover that is on an inside of the outer peripheral cap and is held in a state of being able to slide forward and backward with respect to the outer peripheral cap. The outer peripheral cap has a guide component configured to guide sliding of the cartridge cover forward and backward, a stopper configured to prevent the cartridge cover from coming loose from the outer peripheral cap, and an engagement component that can engage with the pharmaceutical injection device main body.

Pharmaceutical cartridge holding unit, and pharmaceutical injection device provided therewith

The pharmaceutical injection device includes a pharmaceutical syringe mounting portion () provided within a main body case () and to which a pharmaceutical syringe () is removably mounted, a piston () provided movably with respect to the pharmaceutical syringe () mounted to the pharmaceutical syringe mounting portion (), a drive mechanism () for driving the piston (), a controller () that is electrically connected to the drive mechanism (), a display section () that is connected to the controller (), and an encoder () that is connected to the controller () and detects the amount of the pharmaceutical remaining inside the pharmaceutical syringe (). The controller () displays a warning on the display section () recommending removal of the pharmaceutical syringe () from the pharmaceutical syringe mounting portion () when the presence of a pharmaceutical is detected by the encoder ().

Pharmaceutical injection device

This pharmaceutical injection system is provided with a pharmaceutical injection device, a charging device, a detector, and an alarm section. The pharmaceutical injection device has a main body case and a pharmaceutical syringe mounting portion provided within the main body case and to which a pharmaceutical syringe is removably mounted. The pharmaceutical injection device is placed in the charging device, and the charging device has a charger for charging the pharmaceutical injection device. The detector is provided to the pharmaceutical injection device and/or the charging device and detects whether or not the pharmaceutical syringe has been mounted to the pharmaceutical syringe mounting portion. The alarm section is connected to the detector and emits an alarm when it is detected that the pharmaceutical syringe has been mounted onto the pharmaceutical syringe mounting portion.

Pharmaceutical injection system

This pharmaceutical injection device comprises a main body case () that has an injection needle insertion and retraction opening (); pharmaceutical syringe mounting portion () that is provided within the main body case (); a piston () that is provided movably with respect to a pharmaceutical syringe () that is mounted to the pharmaceutical syringe mounting portion (); a drive mechanism () that drives the piston (); a controller () that is electrically connected to the drive mechanism (); and a display section () that is electrically connected to the controller (). The controller () updates the display content that is displayed on the display section () according to the number of times the drive mechanism () has been driven, and saves this updated display content in a memory (), so that when the drive mechanism () has been driven a specific number of times, the display contents during the various instances of drive that were saved in the memory () are combined.

Disclosed is an injection device for properly dissolving pharmaceutical agents contained in a two-compartment syringe having slidable front and rear walls, and then performing portionwise multiple injections. The injection device comprises a front casing designed to enclose and hold the two-compartment syringe with a double-ended needle attached to the front end of it, a rear casing designed to receive the thus held two-compartment syringe being inserted in the rear-end first manner, and to lock and hold the front casing, a piston rod placed in the rear casing and designed to push from behind and carry forward the slidable rear wall, wherein the piston rod can be pushed forwardly from behind the rear casing, and a spring provided so that, when the front end of the piston rod is moved backward, the spring may be once compressed and then push the piston rod to a forward position again, and forwardly drives the slidable rear wall to abut on the slidable front wall.
