    Abstract: A drive mechanism suitable for an injection device includes a housing, a piston rod at least axially movable relative to the housing, and a drive member which is coupled to the housing via a first clutch such that a relative rotation of the drive member about an axis of rotation with respect to the housing is prevented during dose setting and is allowed during dose dispensing. The drive member engages the piston rod such that a rotation of the drive member causes an axial movement of the piston rod. Re-engagement of the first clutch causes rotation of the drive member with respect to the housing in a direction moving the piston rod in the proximal direction.

  • Publication number: 20110178468
    Abstract: A medicinal fluid injector having branch lines to inject a ringer solution together with a treatment solution is provided. If the vein of the patient is clogged, the treatment solution is not injected into the patient, but flows back into the ringer solution, which is injected into the patient through a free fall scheme. If the vein is open, the medicinal fluid is excessively injected at a time, causing fatal accident to the patient. To solve this problem, a check valve is installed in an injection tube to prevent the medicinal fluid or the blood from flowing back into the ringer solution even if pressure difference occurs in the medicinal fluid injector. If the medicinal fluid stagnates, an alarm is generated to notify medical staffs of the emergency, so that medicinal fluid injector is safely used.

  • Patent number: RE41956
    Abstract: A limiting mechanism which prevents the setting of a dose, which exceeds the amount of liquid left in a cartridge of an injection device, is disclosed. The injection device is the type where a dose is set by rotating a dose setting member relative to a driver and away from a fixed stop in the injection device. The dose setting member interfaces the driver such that the dose setting member can be rotated in one direction without rotating the driver. The dose is injected by rotating back the dose setting member which during the backward rotation carries the driver with it. Rotating the driver causes the piston rod to move forward inside the cartridge and expel some of the liquid contained in the cartridge. The driver is provided with a track having a length which is related to the total amount of liquid in the cartridge and which track is engaged by a track follower coupled to the dose setting member to follow rotation of this dose setting member.

  • Patent number: RE43329
    Abstract: A medicament-dispensing system includes a cartridge for housing and actuating an accordion-like vial-dispenser for dispensing a calibrated amount of medicament by means of a single actuation motion which sequentially loads the vial-dispenser and dispenses the loaded medicament. The vial-dispenser has a front bellows portion, a rear bellows portion, an internal piston mechanism, a medicament storage chamber and a dosage cavity. The cartridge has a trigger mechanism which acts in concert with a notched lever and a wedge-shaped arm internally located in the cartridge to sequentially load the dosage cavity with medicament and discharge it. Depression of the trigger mechanism simultaneously extends, by means of the notched lever, the front bellows portion and compresses the rear bellows portion to load the dosage cavity with medicament.
