Die Erfindung betrifft eine Medikamentenabgabe-Vorrichtung zur Abgabe eines Medikaments innerhalb eines Lebewesens mit einem Gehäuse (2), mit einer innerhalb des Gehäuses (2) angeordneten Medikamenten-Speichereinheit (3) zum Speichern eines Medikaments, wobei die Medikamenten-Speichereinheit (3) zumindest bereichsweise eine flexible Wand (4) aufweist, mit mindestens einer in einer Außenwandung (8) des Gehäuses (2) angeordneten Medikamenten-Abgabeöffnung (16) zur Abgabe des Medikaments (5) und mit einem mit der flexiblen Wand (4) der Medikamenten-Speichereinheit (3) in Kontakt stehendes Quelleelement (6) zum Herausdrücken einer Menge des Medikaments (5) aus der Medikamenten-Speichereinheit (3), wobei ein mit dem Quellelement (6) in Fluidverbindung stehendes Fluid-Speicherelement (12) vorgesehen ist.
摘要:
A system for the metering and delivery of small discrete volumes of liquid, comprised of a minimal number of inexpensive components. Fluid (103) is moved rrom a resrvoir (102) through a displacement chamber (104) by movement of a plunger (112). The plunger (112) is moved from a first limit (105) to a second limit (106) by an acuator comprised of a shape memory alloy (114) ans biasing spring (115). Electrical current is supplied to the shape memory alloy (114) by a control circuit (116) that cycles the movement of the plunger (112).

摘要:
The invention refers to an electrically actuated, needle-free injection device. The main field of application is drug delivery. The device is based on a piezoelectric actuator (11). The device enables controlled, continuous, tuneable drug delivery. The device enables painless injection, personalized and programmable dosage profiles. The device is designed, both to pierce the epidermis for trans-epidermal drug delivery and to deliver controlled amounts of fluid (transdermal, electronic pill and implantable drug delivery). This type of device enables personalized drug delivery and is an enabling component for closed-loop drug delivery systems.

摘要:
An automatic stop valve formed in a container of a medical fluid administration system includes an electrical field that attracts the float (50) and valve seat (70) together to shut off flow from the exit port of the container when the fluid within the container is reduced to a predetermined level. One or both of the float and valve seat creates an electric field that attracts the other, which is made of a non-magnetic dielectric, into engagement. In one embodiment, the valve seat is formed of an electret that creates the electric field attracting the float to it to stop flow. In another embodiment, the float comprises an electret that attracts the float to the dielectric valve seat. In yet another embodiment, both the float and valve seat include electrets of opposite polarity that attract each other into engagement. The lack of magnetic and metallic materials makes the shut off valve suitable for use in an MRI environment.
摘要:
A pressurised metered dose inhaler (1) comprising: a reservoir (2) for containing pressurised product, a valve (9) having an inlet (11) communicating with the reservoir and an outlet (14) through which product is dispensed in use, a piece of magnetisable material (5), an armature (8) extending into proximity with the valve, and an electromagnet (7) surrounding at least a portion of the armature. Wherein the armature is coupled to, or forms part of, the valve such that controlled energisation of the electromagnet causes the armature to be either attracted to or repelled from the piece of magnetisable material one or more times to operate the valve for a controlled time period to effect dispensation of a metered dose of pressurised product from the reservoir through the valve outlet.
