A personal protective device (PPE) including a face cover assembly and a bodysuit configured to be worn by a human user. The device protects users against airborne aerosol particles containing viruses or other infectious agents while enabling improved flexibility relative to prior art designs. The device includes a helmet-like” rotating face cover assembly that fits over the user's head and attaches to a collar on the biohazard bodysuit. This rotating face cover assembly has a plurality of different mask sides, each with differing geometries or other properties. The device enables a user to can rotate the cover and select a given mask side that best meets that user's needs. The different mask sides can accommodate different facial geometries, eyewear types, and use cases.

The invention relates to a modular, portable, air purifier device capable of supplying filtered or otherwise conditioned airflow to an individual. More specifically, the present invention provides an air purification system that allows for the remote detection and analysis of local ambient air quality and transmit that information to wirelessly connected devices.

A method of treating a spinal disk according to the present invention can include inserting an alloplastic bulking agent into the spinal disk to treat the defect. The alloplastic bulking agent has a plurality of microparticles and a suspending agent comprising hyaluronic acid. The bulking agent results in at least one of sealing the defect, increasing a pressure of the disk, increasing a height of the disk, improving stability of the disk and improving structural integrity of the disk.

A magnetic quick connect for a fluid delivery system includes a male coupling member and a female coupling member. The male coupling member defines a first outer fluid communication path and includes a first magnetic material. A first inner member is disposed within the first outer fluid communication path and defines a first inner communication path. The female coupling member defines a second outer fluid communication path and includes a second magnetic material. A second inner member is disposed within the second outer fluid communication path and defines a second inner communication path. The male and female coupling members are detachably held together by an attractive force between the first and second magnetic materials such that the first and second outer communication paths are held in fluid communication, and the first and second inner communication paths are held in fluid communication.
