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.

A syringe includes a holding portion that accommodates an injection objective substance, a driving portion that applies injection energy, and a nozzle portion that includes a passage for injection, with these portions being loaded into a housing independently, whereby a state where the injection objective substance can be injected is established. The syringe includes a regulating means for regulating a loading position of the holding portion and the driving portion within the housing so that a loading state, where the holding portion and the driving portion are always loaded in the same order into the housing, is established for injection of the injection objective substance. Due to this, it is possible to facilitate injection of injection liquid ideal for various purposes and to improve user's convenience.

This invention pertains to an advanced implantable surgical array system, wherein array elements, composed of hydrogels or organogels, are intricately connected by a flexible thread. These elements are uniquely embedded within the device through a novel method that involves casting the hydrogel or organogel directly around the thread from a liquid/fluid precursor solution, which upon drying or cross-linking, integrates the thread into the array elements without the necessity for traditional threading techniques. The disclosed arrays are versatile, capable of being configured into various structural forms including single particle arrays, chain-like arrays, as well as two-dimensional and three-dimensional matrices. This innovative approach not only facilitates controlled drug delivery over extended periods but also incorporates features to prevent element migration and enables the device to assume expanded or compressed configurations for ease of implantation.
