Abstract: A compound membrane breathing tube for use in spirometric applications is provided. The compound membrane comprises a first sheet and a second sheet of flexible sheeting connected together along the periphery thereof, and each of the sheets has an opening cut therethrough to create a flap. The flap of the first sheet overlaps the flap of the second sheet so as to present a higher relative resistance to airflow through the breathing tube at lower airflows.

Abstract: A wearable tubing safety vest configured to harness medical treatment delivery tubing and/or communication cables. The tubing safety vest comprises a vest component having a body-encompassing component cooperable with a plurality of releasably securable flaps, and an elongate tubing harness configured to releasably receive and retain therethrough at least one of medical treatment delivery tubing and communication cables. The tubing harness may be securely engaged with the vest component or alternatively, at least one hinge component can be interposed the vest component and the tubing harness. The vest component is configured for demountably encircling a mammalian body torso, e.g, a human infant torso, juvenile torso, or an adult torso. The tubing harness may be demountably engaged with the front or with the back of the vest component. The wearble tubing safety vest may be optionally configured for demountable engagement about an animal's torso.

Abstract: Ergonomic syringe systems provide attachments that may be used to allow users to dispense or draw in fluid with increased operator comfort and reduced risk of repetitive strain injuries. The disclosure describes supports for holding syringes that permit one-handed operation, handles that are removably attachable to syringe plungers and hand supports that are removably attachable to syringe barrels.
