Device for administering an injectable product

Injection device ( ) for injecting fluid from a fluid container ( ) equipped with a piston ( ), comprising an actuating device ( ) having a rod-shaped driven member ( ) having a structured surface, a control button ( ) being movable in axial direction, and a hollow cylindrical counter component ( ) having a structured internal sleeve and said counter component matching the rod-shaped driven member ( ). When twisting the counter component ( ) in relation to the driven member ( ), the driven member ( ) can be shifted freely in axial direction. This allows the free return of the driving member&mdash;without the need for additional control elements&mdash;only when the patient releases the driven member ( ) by turning it, i.e. by a conscious additional operation.

Injection device for injection of liquid

The invention relates to an injection device for injecting a selectable dose of a liquid substance from an ampoule, located in an ampoule holder, comprising a piston and a sleeve-shaped mechanism holder, mechanically coupled thereto, in the interior of which a longitudinally shiftable shaft is provided which acts on the ampoule.

Injection device

An injection device for injecting a preselectable dose of a liquid substance from an ampoule (,) with a stopper (,) located in an ampoule-holder (,) has a sleeve-shaped mechanism holder (,) mechanically linked to the stopper (,) and containing a sliding rod (,) which acts on the ampoule (,). The sliding rod (,) is surrounded by a sliding sleeve (,) mechanically coupled to the ampoule (,) and closed at its upper end by a lid (,). A dosing sleeve (,) is provided with a stepped member (,) arranged at the upper end of the mechanism holder (,) to preselect the dose of liquid substance to be injected. The dose to be administered can be adjusted by turning the dosing sleeve (,) provided with the stepped member (,).

Injection device for a liquid medicament

An apparatus for controlled delivery of a liquid consists of a delivery unit which comprises a liquid container (3) having at least one movable wall (12) and a liquid outlet which is provided with a flow restriction, and a power unit which comprises a second container (21) which also has at least one movable wall (29) and wherein a vacuum may be established, and a mechanical coupling (31) between the movable wall (12) of the liquid container(3) and the movable wall (29) of the second container (21). The delivery unit and the power unit are connected together coaxially when the apparatus is prepared for delivery, and in this connecting together, the movable wall (29) of the second container is displaced by means of the mechanical coupling (31) such that the vacuum is established. The ambient atmospheric pressure then acts against this vacuum, and this pressure is transmitted by the mechanical coupling (31), which is directly acting on the movable wall (12) of the liquid container (3) such that the liquid is forced out through the outlet (4) and the restriction therein.

Apparatus for controlled delivery of liquids

Glucose measuring device

A sensor is used to detect a substance component in an aqueous solution. This sensor has electrically conducting and mutually insulated electrodes (7) which can be connected to a data-recording device. A sensor membrane array responsive to substance components to be detected includes several individual membranes (2) in rows or row-column arrays mounted on a flat support (1).

Sensor array

A medical inhaler generates an aerosol of pharmaceutically effective medication to be absorbed by the respiratory tract of a patient includes a reservoir (1) of liquid medication, a conveyor (2) to expel the liquid from the reservoir, an atomizing vibrator (3) and a feed line (4) to conduct the liquid between the reservoir and the vibrator. The conveyor and the vibrator can be controlled by a process controller (15) which can include a microprocessor. Discharge of liquid medicine is both coordinated with the vibrator and accurately dosable and achieves optimal atomization of the medicine.

Inhalation device

Injector display

An injection pen apparatus (30) for medicament injection including a medicament cartridge assembly (31) formed to receive and contain a medicament therein. A holding sleeve (34) is provided which is dimensioned to receive the medicament cartridge assembly (31) therein which mates with a solution transfer device (35) including an axially movable displacement rod (36). The injection pen apparatus (30) further includes a coupling mechanism (37) removably coupling the solution transfer device (35) to both a plunger (32) slidably movable in the cartridge (33) and to the holding sleeve (34). A sleeve mounting assembly (40) of the coupling mechanism (37) removably mounts the coupling mechanism to the holding sleeve (34). A locking device (41) is included which is formed and dimensioned to require joining of the displacement rod (36) relative the sleeve mounting assembly (40) after uncoupling of the rod from the plunger (32) and before uncoupling of a remainder of the solution transfer device (35) from the holding sleeve (34).

Injection pen solution transfer apparatus and method

A medication dispensing device comprising a cartridge for containing an injectable product therein and an injector attached to the cartridge. The injector includes a drive mechanism comprising a dosage sleeve having a dosage knob at the proximal end thereof and a threaded rod coupled to the sleeve and axially advanceable into the cartridge upon clockwise rotation of the knob for dialing up a desired dosage to be injected. A ratchet mechanism is disposed in the injector housing and includes a rotatable piece secured to the dosage sleeve for rotation therewith and a locking seat in engagement with the rotatable piece. The ratchet mechanism permits rotational movement of the sleeve in the clockwise direction only. A disengaging mechanism is secured to the housing of the LCD assembly and includes a pin that extends into and engages the rotatable piece of the ratchet mechanism such that axial movement of the pin causes corresponding axial movement of the stationary piece. Upon depressing the outer surface of the disengaging mechanism, the pin and the rotatable piece are moved axially away from the seat sufficiently enough to permit a user to rotate the dosage knob in a counterclockwise direction to accurately dial back an accidental overdose measurement without removing the cartridge from the injector.
