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.

The invention relates to a respiratory air purifier device. In order to provide an improved respiratory air purifier device which is able effectively to retain viruses, a respiratory air purifier device 101 is proposed for retention of viruses from respiratory air flowing through the device 101, the latter having an interface 110 designed such that it can be placed by a wearer sealingly onto at least one respiratory opening, a hollow-fibre dialyser 120 as a filter, and a connection piece 130 between the interface 110 and the dialyser 120, wherein interface 110, dialyser 120 and connection piece 130 are configured in such a way as to form an airtight fluid channel which fluidically connects the interface to either only the exterior of the hollow fibres X or only the interior of the hollow fibres I of the hollow-fibre dialyser 120, and wherein the purifier device 101 is designed in such a way that, in at least one flow direction E, A, each flow path pE, pA that runs completely through the purifier device extends through the pores of the hollow-fibre membranes, i.e. transversely with respect to the hollow-fibre membrane, of the hollow-fibre dialyser 120.

An embodiment of a positive pressure loose-fitting head device, such as a hood, helmet or headgear, with exhaustion conduit directing exhaust into user's PPE is shown; there may be an outflow/exhaust drain; there may be a outflow/exhaust tube/conduit under shroud into PPE; there may be connections for add-ons (controls, dampers, valves, diffusers, filters . . . ); there may be an outer shroud and an inner shroud; there may be purified air from power unit; there may be an inflow location.

A face mask that uses a super sticky substance that is sprayed between the 3 material layers of the mask and in its exhaust valve filter to trap and hold particles or microbes when breathing in and out and replicates the body's own sinus defenses in filtering air via cilia hairs and sticky mucus.

A breathable mask includes a main body, a breathing tube, a head strap and a chin strap or support. The breathing tube can be in fluid communication with the interior of the main body. The head strap and a chin strap or support form a three-point fix from a user’s head to the main body of the mask.

A pressure safety device is used with a bag valve mask (BVM) for preventing over-pressurization. The BVM includes a bag assembly having a bag connector for detachably mating to a mask connector on a patient mask. The pressure safety device has a housing with a bag port, a mask fitting, and a flow path from the bag port to the mask fitting. The bag port detachably connects to the bag connector on the BVM, and the mask fitting detachably connects to the mask connector on the BVM. The pressure safety device includes an automatic flow reduction valve located on the flow path in the housing and impedes flow when pressure on a bag connector side of the valve exceeds a maximum threshold value.
