Disclosed herein is an apparatus for preventing fogging in a head worn apparatus, in accordance with some embodiments. Further, the head worn apparatus covers a portion of a head of a user. Further, the apparatus comprises an elongated body, an attachment mechanism, and a fan assembly. Further, the elongated body extends from a first end of a first portion to a second end of a second portion. Further, the elongated body is curved around an axis perpendicular to the elongated body making the first portion substantially perpendicular to the second portion. Further, the elongated body tapers from the first end towards the second end. Further, the attachment mechanism is configured to be coupled with a portion of the head worn apparatus. Further, the at least one fan assembly is configured for circulating airflow in the head worn apparatus.

Provided is a powered air blower unit for delivering air flow to a user with constant air flow or varying speeds of air flow. The air blower unit may also include a filter for purifying the air.

A snore blocking helmet for comfortably minimizing snore impact on others includes a helmet body having a front portion, a rear portion, a right portion, a left portion, a top portion and a bottom perimeter forming an inside. The front portion has a visor aperture and a plurality of vent apertures extending through to the inside. A visor is rotatably coupled to the helmet body to cover and alternatively uncover the visor aperture. A plurality of fans is coupled within the inside adjacent the plurality of vent apertures. A control housing is coupled through the front portion. A plurality of controls is coupled to the control housing and is in operational communication with the plurality of fans. A power source is coupled to the control housing and is in operational communication each of the plurality of controls and the plurality of fans.

A surgical apparel system including a surgical helmet including a peripheral device and surgical garment. The surgical helmet comprising a face frame, a sensor, and a coupling member at least partially disposed within a recess of the face frame. The surgical garment configured to be at least partially disposed over the surgical helmet to provide a barrier between a medical environment and a wearer, the garment comprising an attachment element configured to removably engage the coupling member of the helmet to couple the garment to the helmet. The sensor positioned and configured to detect when the attachment element is engaged with the coupling member and to transmit a signal a controller related to operation of the peripheral device based on the engagement of the attachment element with the coupling member. The controller coupled to the sensor configured to control the peripheral device based on the signal from the sensor.

A surgical apparel system including a surgical helmet to which a garment may mounted. The surgical helmet includes an electrically powered peripheral device, such as a ventilation assembly, and a headband for removably securing the surgical helmet to the head of a wearer. The headband comprises a rear a portion including opposing ends defining a contact point configured to contact the head of the wearer. The rear portion may also comprise a support member disposed between the opposing ends. The support member may be offset distally from the contact points such that the support member defines a void between the head of the wearer and the headband to allow the hair to collect between the head of the wearer and the support member.

A protective headgear includes two air chambers connected through a fan. Each air chamber has a fabric filter with a large surface area. A frame with a fan compartment and headband engages a person's head and forms a boundary to air flow around the head between the two air chambers. Air flows between the two air chambers primarily through the fan. One air chamber is formed above the head and is at lower pressure than air outside the headgear. Another air chamber is formed around the face and is at higher pressure than air outside the headgear. The fan draws air through a fabric filter to provide filtered air into the air chamber around the face, providing breathing volume and positive pressure protection. Exhaled air dissipates out of the headgear through a fabric filter forming part of the air chamber around the face.

A protective shield features a single-piece transparent dome or shell having a rear opening through which facial and cranial regions of a user's head are received, thereby providing improved coverage over conventional face shields that cover the face only. Inward protrusions at a transitional region between the facial and cranial portions of the shield rest against the forehead to offset the facial portion of the shield forwardly of the user's face to allow airflow, optionally introduced from an external fan via an airflow channel integrally formed in the cranial portion. A flexible connector clip has a J-shaped profile for engaging an out-turned flange around the boundary of the shield s rear opening, to enable clipped connection of a bib or shroud. Support protrusions in an underside of the cranial portion maintain airspace above the head, which is further optimized by a rearwardly sloped incline of the cranial portion.

A necklace-type fan includes: a necklace part which has a curved tube shape, and has a plurality of wind blowing holes formed in a longitudinal direction of the necklace part; a wind generation part which has an interior being in communication with the necklace part, and has a fan installed to pump the wind into the necklace part; and a control unit which adjusts a rotational speed of the fan, wherein the wind introduced through the wind generation part is discharged through the wind blowing holes while being changed in intensity by the control unit.

A personal protection system for providing a sterile barrier around medical/surgical personnel. The system may include a head unit over which surgical garment such as a hood or a toga may be suspended over. The surgical garment may include a sterile material and a shield configured to be disposed in front of the wearers face when disposed over the head unit. The shield may comprise an anti-reflective coating configured to reduce the glare observed by the individual through said shield. The head unit may comprises a light assembly that is disposed on the wearers side of the surgical garment, and an inner surface of said surgical garment may comprise a light reflective material configured to reduce the amount of light emitted from said light assembly that is reflected back toward the individual.

A device enables a wearer to obtain a personal zone of cooling effect. Specifically, a headwear is provided that incorporates a stabilizing and aerating platform to house and support an array of photo-voltaic cells that in turn power strategically placed and positionable personal variable speed fans. The device anticipates and counters the power decreases typically encountered by photo-voltaic cells when operating in elevated temperatures. The present invention, and also provides dual modality of use to provide a smaller photo-voltaic cell array in situations where a sacrifice in power is acceptable relative to a sizing of the device.
