Delivery system for delivering medical or pharmaceutical compounds
10576208 · 2020-03-03 ·

A delivery system for delivering medical or pharmaceutical compounds includes a container, a closure element, an attachment element and a penetration element. The container contains the compounds and has a closed container bottom and an open second end. The closure element makes fluid-tight contact with the inner wall of the container. The penetration element has a hollow needle and moves along the longitudinal axis of the container. The penetration element includes a first link motion portion, and the attachment element includes a second link motion portion. One of the link motion portions is a projection, and the other is a guiding groove. As the projection moves in the guiding groove, the hollow needle of the penetration element moves towards the container bottom and penetrates the closure element. The penetration element moves inside the attachment element towards the container bottom based on how the projection travels in the guiding groove.

A production method for producing a transport and transfer receptacle for at least one fluid medium, for example, for at least one sterile liquid is proposed. The method comprises supplying at least one container for receiving the fluid medium. At least one energy unit is supplied. The energy unit effectsfor example, completeemptying of the fluid medium from the container when the transport and transfer receptacle is used. The fluid medium is introduced into the container and the container is closed. The fluid medium is charged with positive pressure, for example, using the energy unit. The positive pressure is maintained until the fluid medium is removed. Furthermore, a transport and transfer receptacle which can be produced according to the production method and which has at least one packaging is proposed.

High Precision Syringe with Removable Pump Unit
20200016331 · 2020-01-16 ·

A digital syringe is used with conventional polymer disposable syringe construction to be practical in the medical environment. Errors associated with the larger volumes of the syringes (which exacerbate minor errors in plunger position) and the flexibility and dimensional variations of the polymer plungers are accommodated by direct measurement of the syringe plunger position rather than indirect measurement of motor position and inference of syringe plunger position. This direct measurement eliminates mechanical tolerances (stack up) in the motor, gear train, and lead screw on plunger movement, an effect exacerbated by flexibility of the plunger and changes in syringe resistance and medicament viscosity, for example, with different medicaments or when the syringe is refrigerated. The digital syringe may be combined with the motor unit to provide additional versatility.

Medical injection system

A medical injection system adapted for a single-handed injection, the medical injection device comprising a gas compartment configured to contain a gas, the gas compartment comprising a piston, a reservoir intended to contain a drug composition, the reservoir having a proximal portion and a distal portion provided with a fluid exit configured to receive an injection needle, wherein the piston can move proximally between a distal position defining a first volume of the gas compartment to a proximal position defining a second volume of the gas compartment smaller than the first volume, and wherein the gas compartment is in gas communication with the reservoir in order to force the drug composition through the fluid exit, when the piston is moved proximally.
