The present invention relates to a drug delivery system, comprising a reservoir from which set doses are apportioned, a dose setting mechanism by which the relative position of two elements is changed by a distance proportional to a set dose, and a push button by activation of which an element is moved a distance corresponding to the distance proportional to the set dose, further comprises a working cylinder having an open end into which a plunger fits, and a closed end at which an inlet and an outlet port connect the space beneath the plunger with an inlet communicating with the reservoir and an outlet communicating with a drug delivery member, respectively. Valves means at the inlet and outlet control the passages from the reservoir to the working cylinder and from the working cylinder to the drug delivery member, respectively. The cylinder with the plunger, and the injection member are independently exchangeable, disposable parts.

The present invention relates to a transfer device for transferring medicament from a medicament container to a syringe with a needle. The transfer device is arranged for transferring accurate dosages of insulin, growth hormone or other medicaments. The accuracy is ensured by the device comprising means for mounting a syringe to the device, the needle piercing a sealing of the device. Opposite the sealing a piston is arranged, said piston being non-releasable engaged with the piston driver during transfer of the medicament. Thereby the piston is not erroneously drawn from the piston driver, which would otherwise lead to incorrect dosing. Furthermore, the device comprises dosing means including the piston driver.

The present invention relates to a medication delivery device comprising a cartridge assembly, a dosing assembly and optionally a needle assembly. The cartridge assembly comprises a cartridge having a stopper adapted to receive a plunger means. Furthermore, the cartridge assembly has one end sealed with a pierceable sealing, said end comprising coupling means for engaging a needle assembly, and another end comprising coupling means for engaging the dosing assembly. At least one of the coupling means of the cartridge assembly is unitarily moulded with the cartridge. The dosing assembly comprises a plunger means and has coupling means for engaging the cartridge assembly. The cartridge assembly and the dosing assembly are coupled together for delivering selected doses of medication. The cartridge is preferably moulded from a plastic material, such as a transparent material, and may be housed in a cartridge housing for protection of the cartridge. The coupling means may be selected from threaded locks, snap locks, hinged locks, or bajonet locks. The medication delivery device is especially suitable for delivering insulin, growth hormone or other medicines.

A cassette for storing and insertion of a solid medicine peg appears as a unit having a first bore (2) which accommodates the medicine peg (3) and has a diameter corresponding to the diameter of this peg (3), a second bore (4) in coaxial extension of the first bore (2) and having a diameter larger than the diameter of the first bore (2), an inserter having a shaft (5) fitting into the first bore (2) and a guiding head (6) in coaxial extension of the shaft (5) fitting into the second bore. The inserter shaft (5) has one end adjacent to the peg (3) and the other connected to the guiding head (6) which projects from the cassette. The head (6) fits into the second bore with a fitting providing a diffusion tight sealing and the distal end of the unit is closed by a membrane diffusion tightly sealing this distal end.

The present invention relates to a method and a system for producing an elongated drug formulation being suitable for being injected through the skin of a patient with-out the use of a needle or a cannula. The drug formulation is produced by compressing a drug granulate in cavity of a system comprising a roller and a surface, wherein the roller roles over the surface thereby comprising the granulate to the formulation.

The present invention relates to a medication delivery device comprising a cartridge assembly, a dosing assembly and optionally a needle assembly. The cartridge assembly comprises a cartridge having a stopper adapted to receive a plunger. Furthermore, the cartridge assembly has one end sealed with a pierce able sealing, said end comprising coupling device for engaging a needle assembly, and another end comprising coupling device for engaging the dosing assembly. The dosing assembly comprises a plunger and has coupling device for engaging the cartridge assembly. The cartridge assembly and the dosing assembly are coupled together for delivering selected doses of medication. The device further comprises mechanism for securing that the plunger abuts on the stopper during use of the device, in particular when the dosing assembly is releasable coupled to the cartridge assembly. The securing mechanism is preferably a mechanism for preventing the cartridge assembly from being inadvertently released from the dosing assembly. The cartridge is preferably molded from a plastic material, such as a transparent material, and may be housed in a cartridge housing for protection of the cartridge. The medication delivery device is especially suitable for delivering insulin, growth hormone or the like medicines.

A sensor package is provided comprising an implantable sensor having an electrode area and an electric contact area, the package comprising a shielding packaging enclosing at least the electrode area of the sensor while exposing the electric contact area. The sensor package fascilitates handling of the implantable sensor and provides for the possibility of sterilising the electric contact area leaving the electrode area protected.
摘要:
The present invention relates to a medical article for containing a pharmaceutical protein preparation comprising at least a first component and a second component, having at least one surface coated with a coating to reduce the friction between the two components and to reduce the protein adsorption to the coating. The coating is a hydrophilic coating whereby the hydrophilicity of the surface of the coating as measured by the water contact angle is below 90°, and the long term static friction forces between the first and the second component are below 14 N. The coatings according to the present invention are especially suited for permanently coating in ternal surfaces of containers equipped with stoppers for storage and administration of liquid protein preparations, such as insulin preparations. The coating is preferably a silicon-containing coating, such as a poly(dialkyl siloxane) oil or copolymer. The invention further relates to a process of producing a component of a medical article coated as described above, comprising adding the coating material to the component material prior to molding and subsequently molding the component from the mixture, or molding the component from the component material and subsequently applying the coating material to the at least one surface of the component, and hydrophilizing the coating material prior to the molding or after the molding. Also the invention relates to a coating as defined above for articles having at least a first component and a second component.
摘要:
A medicaments, container for storing a liquid medicament comprising one or more active medicaments, water and at least one preservative has a preferably cylindrical wall defining an interior space for such liquid medicament. The wall includes at least two opposed portions composed of a polymer material with a thickness of between 0.3 mm and 3 mm, a light transmission at 400 nm of 25% or more measured through the opposed container wall portions when the container is filled with water, using a standard spectrophotometer and air as reference. The polymer wall portions are of a material comprising at least 70% by weight of a linear optionally branched polyolefin material, the olefin monomer being selected from ethylene, propylene, butylene or a mixture thereof The polyolefin material has a crystallinity above 35% by weight, measured by differential scanning calorimetry, by cutting pieces from the container walls and heating them in an aluminum pan from 10.degree. C. to 270.degree. C. at the scanning rate of 10.degree. C./min, recording and integrating the melting endotherms, and using the value of 209 J/g for 100% crystalline polypropylene as a reference.
