Abstract
A biomedical haemostatic powder dispenser (1) by which individual doses of powdered medication that are stored in respective chambers of a rotatable carousel (22) are fluidized for delivery to a targeted treatment site (e.g., a wound in order to stop bleeding). In particular, a squeeze handle (7) is activated (i.e., depressed) so as to cause a blast of gas under pressure to be applied from a gas reservoir (30) to a particular one of the powder-filled chambers of the medication carousel so that a single measured dose of medication is entrained and delivered to the patient. At the same time that the squeeze handle is activated, the medication carousel is rotated so that a different powder-filled chamber is moved within a fluid path between the gas reservoir and an outlet nozzle tube (10) of the dispenser and a kit for dispensing a powder.
