Abstract: Injection devices are known for the self administration of a medicament by patients. The medicament is typically contained within a cartridge located within an injection device. It is a problem that injection devices should be small enough to fit into a jacket pocket or a hand bag without difficulty. Concurrently, the injection device must be of a size that enables a piston used to drive a cartridge bung within the cartridge to both to a maximum dispense position within the cartridge and to be fully withdrawn from the cartridge to allow for replacement of the cartridge.

Abstract: A medicament delivery device is disclosed having dose dial means 6,8 to determine a quantity of medicament to be delivered. The medicament delivery device is also provided with selection means to select whether the quantity of medicament to be delivered is determined as a multiple of a first quantum of units or as a multiple of a second quantum of units.

Abstract: A person having diabetes will often be required to take both slow acting and fast acting forms of insulin. It is important to be able to distinguish readily between medicament cartridges containing different medicaments. The present invention enables a user to distinguish readily between medicament cartridges containing different medicaments. A medicament cartridge and adaptor top assembly is provided, the medicament cartridge comprising a cylinder having a bottleneck provided with a flange at a first end, a fluid impermeable membrane covering the first end, a cap beaded under the flange to retain the fluid impermeable membrane in place, and a piston displaceably located within a second end of the cylinder, and the adaptor top comprising a sleeve having a body portion and a tapered portion, the tapered portion being provided with a smaller diameter end, the smaller diameter end being located beneath the cap.

Abstract: An injection device for injection of a medicament from a first medicament cartridge (40) is disclosed. The injection device comprises a drive mechanism (42) for selectively dispensing the medicament from the first medicament cartridge (40), a dial dose mechanism (12, 14) by which a user may determine a required dose of medicament to be dispensed, an electronic control unit for controlling the operation of the drive mechanism (42) in response to the dial dose mechanism (12, 14) and a display panel (10).

Abstract: An injection device (2) having a drive mechanism (42) to expel selectively a dose of medicament from a medicament cartridge (40) through a needle arrangement is disclosed. The injection device (2) also comprises a processor to control the drive mechanism (42), a dispense button (18) to generate a signal to the processor to cause the medicament to be expelled and a priming detector to detect a predetermined orientation of the injection device. When the predetermined orientation is detected the processor will only actuate the drive mechanism (42) to expel a small amount of medicament.

Abstract: Method for measuring friction in a hair sample, comprising: (a) providing a friction member; (b) drawing it through the hair, generating a frictional noise signal; and (c) capturing the signal by a noise sensor. Device suitable for use in said method, comprising comb means having a plurality of tines and a noise sensor arranged to capture frictional noise generated by passage of comb means through the hair. System for assessing the level of damage in a hair sample, comprising: (a) defining hair categories; (b) associating with each category a standard trace representative of the frictional noise signal generated when a standard sample in that category is subjected to said method; (c) assigning the sample to one of the categories; (d) carrying out said method on the sample; (e) visually displaying the frictional noise signal generated as a trace; (f) and comparing the sample's trace with the standard trace associated with the category.
