A method of reconstituting and administering an injectable fluid distributed to practitioners in dry-form includes receiving a drug or medicine in dry form, selecting a reconstitution concentration for the drug or medicine, reconstituting a desired number of units of the drug or medicine by adding diluent to the dry-form drug or medicine, selecting a syringe having units marked according to the selected reconstitution concentration, drawing up a desired number of drug or medicine units using the selected syringe, and administering a desired number of units according to the unit markings on the selected syringe. Such a syringe includes a barrel, a plunger assembly that has a plunger handle and a piston, a needle, and a needle cap. The syringe includes a visual indicia, representing a first drug concentration contained in the barrel, that is distinguishable from a corresponding visual indicia, on a second syringe, representing a second drug concentration.

A strap attachment system includes a frame member having an opening, a strap, and a tab having a body and an attachment element defined by the body. The tab connects to the strap. A fastener element connects to the tab and is detachably and slidably mountable to the frame member by the opening.

A multi-component binding-strap fastener for binding volumetric objects with a strap tension a strap around the volumetric objects is described. The strap may engage the binding-strap fastener by bending an end of the strap to secure the strap through a plurality of apertures in the binding-strap fastener, by friction, by pressure, by any combination of the foregoing, or other suitable manner. A binding-strap fastener may lock in a closed position using a locking device, such as an over-center mechanism, a retaining clip, or a strap-engaging portion. The A binding-strap fastener has a hinge located thereon between a first end of the binding-strap fastener and a second end of the binding-strap fastener, where the axis of rotation is coincident with the hinge and the axis of rotation is located above the volumetric object.

A strap attachment system includes a frame member having an opening, a strap, and a tab having a body and an attachment element defined by the body. The tab connects to the strap. A fastener element connects to the tab and is detachably and slidably mountable to the frame member by the opening.
