A New Powder Blower

Educating the Whistle - Blower

Electric Blower Based Portable Ventilator

When a patient is unable to breathe or maintain their airway they will most likely be ventilated by a bag-valve-mask. We propose to replace the traditional bag-valve-mask with an electric blower ventilator. This handheld feedback controlled device will automatically compensate for mask leak and enable the clinician to deliver computer controlled respiratory rates and tidal volumes. We have buil...

A unique case of valsalva retinopathy in a conch blower

Purpose Valsalva hemorrhagic retinopathy is a form of preretinal hemorrhage that develops after a valsalva maneuver, leading to rupture of the superficial retinal capillaries. Here, we report a case of valsalva retinopathy secondary to blowing a conch, the first case report of its kind. The patient blew conch, which was part of his daily ritual to pray to God as he was a Hindu priest. Observa...

An Investigation of the Volumetric. Efficiency of a Roots Blower

A Substitute of Roots Blower - Monotooth Rotary Compressor

Having builtin compression process, monotooth rotary compressor can reach larger discharge pressure with higher efficiency and lower discharge temperature when compared with Roots blower. So it is a good alternative for Roots blower used in various fields. In order to put this kind of compressor into market as soon as possible, theoretical and experimental study of the monotooth rotary compress...
