A cartridge set including: a plurality of cartridges; a plurality of holders, each of which has an upper end externally fitted to the outer peripheral surface of each of the cartridges, and has a lower end face whose outer diameter is greater than the outer diameter of the outer peripheral surface of the cartridge; a supporting plate that has a plurality of through-holes, each of which has an inner diameter greater than the outer diameter of the outer peripheral surface of the cartridge and has each of the plurality of cartridges inserted therethrough; a storage box that stores the supporting plate therein; and a lid member that blocks an upper end opening of the storage box.

Cartridge set for manufacturing syringe and method for manufacturing dual-chamber type combined container-syringe

A combination container/syringe () provided with an outer cylinder () that forms a cylindrical shape centered on an axial line (O); a front stopper that is inserted into a distal end side of the outer cylinder (); and a cylindrical tip () that is fitted to an outer periphery of the distal end of the outer cylinder via a fitting hole () at a base end side, and that has a bypass chamber () that houses the front stopper at a front side of the fitting hole, in which an inner diameter of the bypass chamber is formed larger than an outer diameter of the front stopper, and a plurality of ribs () that protrude toward an inside in a radial direction and extend in the direction of the axial line to make close contact with the outer peripheral surface of the front stopper that has moved to the inside of the bypass chamber are provided spaced apart in a circumferential direction on the inner peripheral surface () of the bypass chamber. According to this combination container/syringe, it is possible to effectively eliminate air bubbles in a medicinal solution via a medicinal solution flow-through space that is formed over the circumferential direction between the inner peripheral surface of the bypass chamber and the outer peripheral surface of the front stopper.

Combination container/syringe

A device for sealing a vessel, in particular a cartridge () or a test-tube for accommodating a freeze-dried pharmaceutical product (S), wherein the vessel () comprises at its opening end () an opening edge () and an adjoining longitudinal portion () with an evenly formed inner cross section, including a front plunger () to be positioned inside the vessel () at the longitudinal portion (), is characterized in that the front plunger () is configured to be positioned in the vessel () in a sealing state, in which the front plunger () is fully inserted in the vessel (), or in an exchange state, in which the front plunger () is inserted partly in the vessel () and partly protrudes over the opening edge () of the vessel (), wherein the front plunger () comprises sealing means that are configured to seal the inside of the vessel () against the outside when the front plunger () is positioned in the sealing state, and one or more communicating grooves () that are configured to place the inside and outside of the vessel () in communication with each other when the front plunger () is positioned in the exchange state. Furthermore, a method of manufacturing a sealed vessel () is disclosed.

Device for sealing a vessel and method of manufacturing a sealed vessel

A combined container-syringe includes a body that has an outer tube to be filled with a drug solution. A cylindrical tip is attached to a front end portion of the outer tube and to a front end portion of which an injection needle is attached. A cylindrical safety device is attached on an outer circumferential surface of the outer tube in a freely sliding manner. A first retaining member fixes the safety device in a disengageable manner at a first position where the safety device is separated from the injection needle. A second retaining member fixes the safety device at a second position where the safety device covers the injection needle. A biasing member biases the safety device in the direction from the first position to the second position. A latch releasing member releases the engagement by the first retaining member.

Combined container-syringe

A dual chamber combined container-syringe includes: an outer casing having a bypass portion; a hub lure lock; a front stopper; a middle stopper that seals a pharmaceutical preparation together with the front stopper; an end stopper that seals a liquid medicine together with the middle stopper; a finger grip; and a plunger rod that is connected to the end stopper from the rear end side, wherein a female screw portion twisted around an axis is formed on an inner peripheral surface of the finger grip, and a first male screw portion, a tip of which comes into contact with a rear end of the female screw portion and can be screwed into the female portion, and a first guide plate are formed on an outer peripheral surface of the plunger rod when a part of the middle stopper enters the bypass portion.

Dual chamber combined container-syringe

This combined container-syringe comprising a glass cylinder which can be pre-filled with a drug, an cylindrical tip provided at an exterior portion of an anterior end of the syringe, and a finger grip provided at an exterior portion of an posterior end of the syringe, and a drug is pre-filled therein and sealed by a stopper. Furthermore, an impact absorption part is provided around the exterior portion of the cylindrical tip and a diameter of the impact absorption part is greater than an outer diameter of a fitting part to the cylinder of the cylindrical tip.
