Abstract: A liquid infuser apparatus includes an elastic sleeve mounted on an elongated member and within a collapsible spherical housing to enable it to expand naturally to maintain a constant pressure over the infusion period. A rigid open ended housing into which an infuser may be removeably placed provides a reusable protective housing. Multiple infusers are packaged with a rigid housing in a kit.

Abstract: A cannula support assembly comprises a hub subassembly, which supports the cannula, and a cover subassembly, which attaches to the hub subassembly to sealingly enclose the cannula prior to use and which can be easily removed from and subsequently reattached to the hub subassembly, if desired. Each subassembly is itself preferably fabricated from one or more individually extruded component parts which can be assembled together in a manner lending itself to cost efficient, automated production techniques and which thereby obviates the use of substantially more costly injection molded or compression molded plastic parts. The resulting support assembly is durable, easily attachable to flexible tubing, and readily adaptable to diverse uses, such as a hub and cover for a phlebotomy needle or an inline sampling needle.

Abstract: Described is a stringed instrument construction, particularly a guitar construction, including a seamless, hollow, one piece body portion or sound box molded from a synthetic material. The body can be molded by conventional spin or roto casting techniques. The body portion or sound box is acoustic and can therefore be used for either an electric type instrument or a conventional manual or acoustic type instrument. A neck construction is also described comprising a metal and hardwood laminate which does not allow any significant deflection due to string load.
