摘要:
There is described a water soluble compound having a molecular weight of from about 70,000 to about 2,000,000, and having the formula I,(PS)--X--(HB)--Z IwherePS represents a physiologically acceptable polysaccharide of molecular weight from about 2,000 to about 2,000,000,X represents a covalently bonded chemical bridging group,HB represents a haemoglobin residue, andZ represents an oxygen affinity reduced ligand, containing 2 or more phosphate groups.There is also described haemoglobin linked to an oxygen affinity reducing ligand derived from inositol phosphate, and polymers of such linked haemoglobin.Processes for making the compounds, and their formulation and use as oxygen transporting agents, are also described.
摘要:
There is described a centrifuge provided with a rotor identification system.The rotor identification system includes a rotor (4) having a pair of detectable elements (11, 12), e.g. magnets, spaced by an angular separation characteristic of the rotor (4), detector means (3), e.g. a Hall effect transducer, positioned so as to interact with the detectable elements (11, 12) to generate a signal which is a function of the angular separation and means responsive (20) to the signal to identify the rotor (4).
摘要:
There is described an adjustable dose injection pistol comprising a body assembly (1) including an elongate chamber (8), a piston chamber (3) including a piston (13) slideable in the chamber (8) between filled and discharged positions and means for adjusting (16, 26, 19, 20, 22, 23) one of said positions.The means comprise a selectable plurality of channels (20, 22, 23) included in one of the assemblies (1, 3), the channels (20, 22, 23) being spaced about and parallel to the piston-chamber axis, and an arrestor (19) located on the other assembly (1, 3), the arrestor (19) being selectably engageable with an aligned channel (20, 22, 23) upon movement of said piston (13) between said positions.The channels (20, 22, 23) are preferably located in the piston assembly (3) on a sleeve (16) concentrically mounted with the piston (13) and rotable with respect to the chamber (8).The pistol may be used for the injection of liquids into animals.
摘要:
A device for the administration of powdered inhalation medicament contained initially in a capsule having at least one aperture formed therein, comprising a swirl chamber (1) adapted to receive the medicament capsule; a mouthpiece (2) communicating with the swirl chamber (1) and separated therefrom by a grid (4); at least one air inlet (5) in tangential communication with the swirl chamber (1) whereby air can be drawn through the device via the mouthpiece (2) to cause a swirling air flow through the swirl chamber (1); and a cover member (7), having a continuous substantially planar inner surface, provided on the base of the swirl chamber (1) remote from the mouthpiece (2); said cover (7) being moveable between a first position in which the capsule can be inserted into the swirl chamber (1) and a second position in which the capsule is retained in the swirl chamber (1) and rotates upon air being drawn through the device, thereby dispensing the medicament contained therein.
摘要:
An aerosol inhalation device suitable for use in association with a pressurized medicament container having a valve stem has a spray head adapted to receive the valve stem. The spray head has an outlet orifice of uniform diameter which is provided with a spout to prevent blockage of the spray head. The device is especially useful in the administration of hygroscopic medicaments, for example sodium cromoglycate or nedocromil sodium.
摘要:
A non-pressurized pharmaceutical inhalation composition includes a therapeutically effective amount of a particulate inhalation medicament. The medicament has a mass median diameter in the range 0.01 to 15 .mu.m. A particulate polysaccharide entrapped flavoring agent is included in the composition and has a mass median diameter in the range of 10 to 200 .mu.m. The composition can be used to practice a method for treatment of reversible obstructive airway disease which includes administering the pharmaceutical composition to a patient.
